Description

Liquid crystal board

Technical field

The present invention relates to a kind of method and apparatus of parting glass substrate, described glass basis can be used as the glass basis of liquid crystal display device etc., and has formed the rete of deposition at least one surface of this matrix, such as film or rete.The present invention also relates to liquid crystal board, this liquid crystal board is made up of a pair of base unit that links together, be sealed with liquid crystal between the described a pair of base unit, and polarizer slice (polarizer plate) is connected on the outside surface of base unit, the present invention also relates to make the device of a plurality of such liquid crystal boards by parting glass substrate, described glass basis has many to setting adjacent one another are and the glass basis unit that links together, glass basis is sealed with liquid crystal between the unit, and is connected with polarizer slice on two surfaces of this unit.

Background technology

In routine techniques, usually come parting glass substrate by line, specifically, at first utilize vacuum chuck etc. that glass basis is fixed on the work stage of cutting machine, then on a surface of glass basis, utilize outer most edge by superhard material, the wheel cutter of making such as superhard alloy or adamas forms the linear cut that is called as line, this cut comes down to a kind of slight crack (hereinafter also being referred to as slight crack), and then utilize extrusion equipment, exert pressure along line from the opposite side on the glass basis such as extruder or roller, so that established slight crack is along further splitting perpendicular to the surface direction of matrix, until finally making the glass basis division in the line of glass basis.

The angle of producing from reducing cost is considered, nowadays cut into needed size shape by glass baseplate and make liquid crystal display device and other similar display device big specification, formed film on the surface of the glass baseplate of described big specification in advance, such as ELD (for example ITO film), dielectric film and oriented film etc.When being formed with this glass basis of depositional coating (hereinafter also being referred to as deposited film) on cutting it, caused variety of issue is a unthinkable problem during conventional glass basis is rule.For example, the line of deposited film surface has been caused the damage of the deposited film around the line.This makes the film of deposition be scattered with fine particulate form, and can cause unacceptable product quality.Even there be not the opposite side line of deposited film, the result also can contact with the work stage of cutting machine and causes its generation cut or distortion because of the deposited film surface.

The open No.H11-64834 of Japanese patent application has advised the solution of these unfavorable factors, and this application discloses the conventional method that is used for the big specification glass matrix that the surface is formed with deposited film is divided into the bar shaped part with required size.This method attempt by with the glass surface of deposited film surface opposite one side rule overcome above-mentioned unfavorable.

With reference now to Figure 52, and mainly describe this method by the instructions of the open No.H11-64834 of citation Japanese patent application.Be formed with deposited film 102 on the surface of glass basis 101.By utilize the chuck device be not illustrated, such as vacuum chuck equipment, the mode that makes progress with deposited film 102 is fixed on glass basis 101 on the end face as the surface patch 103 of work stage.In surface patch 103, form straight line opening 104 with predetermined interval, thereby can make when the scoring equipment 105 as the slight crack forming device that is used to form line (being slight crack) moves along opening 104 in the line of the bottom surface of glass basis 101.Work simultaneously by puopulsion equipment 106 and positioning equipment 107 pneumatic or that similar type is implemented, thus the precalculated position that glass basis 101 is moved into one by one.The tip of puopulsion equipment 106 has pushes pin 110, and the tip of positioning equipment 107 has register pin 111.Extrusion equipment 109 is from the deposited film surface pressure of the glass basis end face to surface patch 103, thereby makes glass basis 101 location.

How then will describe this method implements.When surface patch 103 is located in " a " position shown in the dot-and-dash line, by not shown conveyer that glass basis 101 is placed on it, and afterwards owing to the positioning signal that responds unshowned opertaing device makes the register pin 111 of positioning equipment 107 tips drop to the surface of surface patch 103 suddenly.Then, 110 extensions of pushing pin of puopulsion equipment 106 tips so that according to the direction shown in the horizontal arrow among the figure surface patch 103 lip-deep glass basiss 101 are moved, contact with register pin 111 until glass basis 101.Make the position that is cut of glass basis aim at thus with opening 104.Afterwards, opertaing device sends instruction is stuck on the surface patch 103 glass basis 101, then extrusion equipment 109 is moved to and will implement the position of line, and the end face of extruding glass basis 101, then utilize scoring equipment 105 on the bottom surface of glass basis 101, to rule.When scoring equipment 105 repeats to rule, off and on it is transferred to another aperture position that forms line from an opening.By using this method, glass basis 101 by the opening 104 that forms in the surface patch 103 by from the bottom surface underscore.At this moment, the power that glass basis 101 is stuck on the surface patch 103 by chuck device is not enough to offset the line load that scoring equipment 105 is produced, and should deficiency need utilize the surface extruding glass basis 101 of extrusion equipment 109 auto-deposition films to compensate.

Above-mentioned conventional line (cutting) method and apparatus mainly is the glass basis that is formed with diaphragm on the big specification glass material in order to cut.But, for being formed with the glass basis of film thereon such as the ITO film, when utilizing conventional extrusion equipment such as the equipment 109 of the gravity-type shown in Figure 52, the load that causes film to be extruded equipment itself for the line load meeting of offsetting from the below damages.

In order further to reduce the cost of liquid crystal display device, attempted forming film, cutting the glass material of big specification after such as polarizer slice and screening glass, rather than these films that as routine techniques, after parting glass substrate, bond again.Normally in making last processing step of liquid crystal cells, polarizer slice is bonded on the outside surface of glass basis up and down.This technology relates to the relative positioning of film and glass basis, and needs extra step, thereby can not reduce cost.

The thickness of deposited film changes along with the change of its type; Film is several μ m or thinner such as the ITO film, and rete is that 10 μ m-0.6mm are thick such as polarizer slice.For being formed with the glass basis of this rete thereon, can not directly on the film of deposited film, rule.When utilizing conventional method and apparatus to carry out above-mentioned line, exist rete can cause and after line, to cut matrix.

On the other hand, under medium or the small size liquid crystal board situation, particularly screen size is about under 5 feet the situation, conventional manufacture method is: the big specification glass matrix that at first will bond together roughly cuts into the bar shaped glass basis, then handle them in a predetermined manner, such as between them, placing liquid crystal and encapsulated liquid crystals, further they are accurately cut into predetermined chip size then, many individual units have been made thus, and then polarizer slice is bonded in each unit, thereby has made many liquid crystal boards.

With reference now to Figure 53, the liquid crystal board that utilizes conventional method to make is described.Among Figure 53, what illustrate is the external view of conventional liquid crystal board, and wherein figure (a) represents its upside, (b) represents its bottom.Liquid crystal board 550 is made up of a pair of base unit 551a and the 551b that bonds together, and is sealed with liquid crystal between them.The end of base unit 551a stretches out from the end of another unit 551b, and the inside surface of extension 551aa is formed with link 553, can drive liquid crystal board thus.And, bondd respectively on the outside surface of base unit 551a and 551b polarizer slice 552a and 552b, thus the viewing area (not shown) covered.When designed liquid crystal board is when being used to be called as the liquid crystal board of rear-projection liquid crystal display device (this device is realized showing by seeing through from the light of light source), the size of polarizer slice 552a and 552b is roughly the same, and they are positioned opposite to each other, and accompany liquid crystal cells 551a and 551b between them.

Above-mentioned conventional method relates to polarizer slice is bonded in each unit one by one, causes making the non-constant of efficient.Even used special-purpose machine for this reason, the influence of static also can limit the bonding speed (each polarizer slice need 8-10 second) usually of polarizer slice.Therefore, in order to satisfy the requirement (as much as possible make liquid crystal board) of market, need on a large amount of machines, handle a large amount of polarizer slices simultaneously to high yield.This has greatly increased the expense of facilities and equipment, and has increased the cost of final products-liquid crystal board thus.

For example, the open No.H6-342139 of Japanese patent application has proposed to avoid the method for this defective, the disclosed method that is used for making liquid crystal board of this application, at first, the polarizer slice that is formed with line of cut (indicating position to be cut) on the precalculated position is connected to plastic substrate, and then cut this plastic substrate, to produce a plurality of liquid crystal boards along line of cut.According to this method, before the cutting matrix, make polarizer slice be bonded in matrix.This helps to reduce in proportion the step of bonding polarizer slice very much.Therefore, may improve manufacturing efficient, and can not increase the expense of facilities and equipment too much.

But this method has following shortcoming.At first, polarizer slice is folded in polyvinyl alcohol (PVA) and forms between the tac layer, or is formed by acrylic resin-coated polyvinyl alcohol (PVA), and this polarizer slice of formation is the film of the about 0.2-0.6mm of thickness.Therefore, when having formed line of cut on the polarizer slice, the unexpected load meeting that is applied thereto makes the part distortion around the line of cut, has finally caused the warpage or the cracking of polarizer slice.Particularly, when being bonded in matrix, the bonding of polarizer slice should make line of cut be positioned on the precalculated position of matrix.This requires to use high-precision machine, and this is unfavorable for reducing the cost of liquid crystal board.

Secondly, when the cutting matrix, polarizer slice also is cut (even the polarizer slice part of position that has formed line of cut is also by separated from one another).Particularly when the glass basis that uses fragility during as matrix, the nature difference of matrix and polarizer slice is very big, therefore, unless SC, the out of position place of glass basis can split, or polarizer slice peels off beyond expectationly.That is to say, be difficult to carry out can not making the cutting of quality reduction.Therefore, this method also leaves some room for improvement.Incidentally, the open No.H6-342139 of Japanese patent application estimates to have used the plastic substrate similar to the polarizer slice material as matrix, and therefore very natural is not have special their method of cutting of considering.

On the other hand, in the conventional liquid crystal board shown in Figure 53, each base unit 551a and 551b all very thin (when forming, being that about 0.4-0.7mm is thick) by glass, therefore, the bad mechanical property of extension 551aa particularly.Therefore, when from a position when another position is carried liquid crystal board or is assemblied in this sheet the liquid crystal display device, extension 551aa may split or be out of shape or angle of breakage.Therefore, need take special care to handle.

And in recent years, polarizer slice itself can provide multiple function, and this sheet is stacked mutually and form by many sheets with various optical properties.The result is at the edge of the polarizer slice that is bonded in base unit, can find burr and analog usually.This makes and is difficult to liquid crystal board is fitted in the liquid crystal display device, perhaps can cause polarizer slice to be peeled off from matrix unexpectedly.Moreover; thereby be placed under the situation about becoming one with it on the outside surface of polarizer slice at removable diaphragm; when from a position when another position is carried liquid crystal board or is assemblied in it liquid crystal display device; this film can be peeled off from polarizer slice unexpectedly, and scratching polarizer slice itself.

Preferred implementation

The method of the included method and apparatus that is used for parting glass substrate of the present invention, liquid crystal board and manufacturing liquid crystal board is at length described one by one below in conjunction with accompanying drawing.When describing the related accompanying drawing of each embodiment, the parts that play same function in the different embodiments utilize identical Reference numeral to represent as far as possible, and the identical content of repeated description not.

At first, will the glass basis cutting method of first embodiment of the invention be described.The glass basis cutting method of Fig. 1-3 expression first embodiment.The mode that the side view of Fig. 1 (a) represents how to remove the deposited film that forms on the glass basis, and (b) be the front elevation of Fig. 1 (a) of obtaining when seeing of the left side from figure (a).Fig. 2 shows the more details of Fig. 1 operation, and Fig. 3 represents how to form slight crack (line) on glass basis.At this moment, deposited film can be the film of any kind, such as being protective finish or transparency electrode class film, or such as be polarizer slice, resin molding or diaphragm class than thick film.

Among Fig. 1, Reference numeral 1 represents to be formed with on it glass basis of deposited film 1a, Reference numeral 2 expressions are as the gear shaver of firmer chisel, it is used to cut, shave off and remove thus the bar shaped part of deposited film 1a, thereby glass basis 1 is exposed, the work stage of Reference numeral 3 expression placements and fixing glass matrix.Shown in Fig. 1 (b), gear shaver 2 has the cross section that opening angle is the forming V-shape basically of θ.Shown in Fig. 1 (a), when gear shaver 2 is mobile from left to right along the direction that is parallel to the glass basis end face, when thereby the blade at gear shaver 2 tips is pressed on the glass basis 1 and contacts (just the glass surface with glass basis 1 contacts) with the bottom surface of deposited film 1a, deposited film 1a is cut, shaves off and is removed with the form of useless bar 1b thus, in Fig. 1 a, this useless bar is removed along the groove that is essentially V-arrangement of blade.The size of employed power when regulating gear shaver 2 and be crushed on the glass basis according to the thickness of deposited film 1a and material.Being typically, be that its pressure is not higher than 1N (newton) for the resin molding of tens μ m for deposited film, such as thickness, and for the thick film of about 0.5mm, its pressure equals tens N.

In Fig. 1 (a), regulate optimum angle alpha between gear shaver 2 and glass basis 1 surface according to the thickness of deposited film 1a and material, and utilize best angle to carry out the excision of deposited film.Normally about 90 ° of angle beta between gear shaver 2 and the blade.But,,, should make that the result of excision is best according to the angle beta that thickness and the material of deposited film 1a are regulated when deposited film 1a is the thick film of tens μ m or for quite thick film or in other cases.

Fig. 2 has represented how to utilize the cutting of gear shaver shown in Figure 12 realization deposited film 1a and shave off in detail.Bend to the shape that opening angle is the forming V-shape basically of θ by having certain thickness sheet shape material material, formed the simplest gear shaver 2 of the form as the V-arrangement firmer chisel shown in Fig. 1 b, and formed as shown in Figure 2 be always the relief angle of γ along blade.

Fig. 3 is illustrated in by gear shaver 2 formed shaving in the groove 5, by when pressing down as the wheel shape of slight crack forming device line cutter 4, makes it move the mode that forms slight crack (line) 5a along shaving trough roller.Line cutter 4 as the slight crack forming device has roller cutter 4a, and its blade is formed by adamas or superhard alloy etc., and it can rotate at back shaft 4b head lamp brush guard pivot.The edge angle of roller cutter 4a can change between about 60 °-140 ° according to the thickness and the material of glass basis.Therefore, the opening angle of the gear shaver 2 shown in Fig. 1 b is that the definite of θ should defer to such principle: should make to the setting of shaving groove 5 moulding and size, when utilizing roller cutter 4a to form line 5a on the surface of glass basis 1, it can not influence deposited film 1a, otherwise can have a negative impact.

The cutting method of Fig. 4 (a) expression second embodiment of the invention.Compare with Fig. 1 of expression first embodiment, the gear shaver 12 of this moment has different cross sectional shapes.Second embodiment shown in Fig. 4 (a) is with the difference of first embodiment: the blade of the gear shaver 12 that contacts with the glass basis surface does not have the V-arrangement opening, but the radius shown in Fig. 4 (a) is the arc opening of R1.The blade that it is characterized in that gear shaver 12 is that second embodiment of arc section has the following advantages.Can obtain wideer width in the bottom of shaving groove 5 as shown in Figure 3, that is to say, wideer than the width that obtains in the exposed region (bar-shaped zone) on the first embodiment glass basis.This causes the blade location of roller cutter 4a to have bigger space.And unlike embodiment 1, pressure does not concentrate on the point of gear shaver 12 blades.This helps to keep the sharp keen of gear shaver 12 blades in the longer time period.As embodiment 1, determine radius R 1 and opening angle according to the edge angle of roller cutter 4a and the thickness of deposited film 1a.Comprising the others that how to form line etc., the working method of second embodiment is identical with first embodiment, therefore no longer this is carried out repetition of explanation.

The cutting method of Fig. 4 (b) expression third embodiment of the invention.In the 3rd embodiment, the feature of second embodiment is further extended.Specifically, at this moment, the cross sectional shape of the blade of gear shaver 22 tips is that the linear segment (this part contacts with the surface of glass basis 1) of L1 and the sloping portion that opening angle is θ 1 (the surperficial 1a of this part cutting deposited film) are formed by width.In the intersection of linear segment and sloping portion, they are linked together by two little radian r2.This helps to obtain the gratifying deposited film cutting of result and shaves off, and helps to prolong the serviceable life of gear shaver 12 blades.Compare with second embodiment, in the 3rd embodiment that the bottom width of shaving groove 5 is determined by L1, the size of groove 5 is shaved in easier setting.In second embodiment, can come to determine rightly the shape and size of blade, L1 and θ 1 value specifically according to the thickness of the edge angle of roller cutter 4a and deposited film 1a.Comprising the others that how to form line etc., the working method of the 3rd embodiment is identical with first embodiment, therefore no longer this is carried out repetition of explanation.

The cutting method of Fig. 5 and 6 expression four embodiment of the invention.The side view of Fig. 5 (a) is illustrated in the 4th embodiment, by the mode of utilizing two plate cutters 32 positioned opposite to each other and 32 ' that the deposited film that forms on the glass basis is cut, and the front elevation that Fig. 5 (b) expression obtains when the direction shown in 5 (a) arrow is seen.In this embodiment, for the blade that makes roller cutter 4a contacts with the glass surface of glass basis 1 when ruling, by on the direction shown in 5 (a) arrow, make two cutters parallel to each other basically of setting move and keep in touch with deposited film 1a, shave groove 5 thereby in deposited film 1a, formed, cut deposited film 1a thus.For example, two cutters 32 that form and 32 ' the sidepiece shape that should have shown in Fig. 5 (a), and these two cutters are configured to have the ε cutting angle, thickness and material according to deposited film come the suitably value of definite this cutting angle, this value for example is the scope at 20-50 °, and when these two cutters are pressed to glass basis, they are moved according to the direction shown in the arrow.Shown in Fig. 5 (b), in the 3rd embodiment, at interval the tiltangle 2 between L2 and two cutters 32 and 32 ' determine should make when on glass basis, ruling, the blade of roller cutter 4a do not influence deposited film 1a.

In the 4th embodiment, even after deposited film 1a is by two flat sheet type cutters 32 and 32 ' cutting, deposited film is the useless bar 1b form shown in Fig. 5 (b), therefore, need to give up bar 1b shaves off and in downstream procedures with it removal.For example, can utilize gear shaver shown in Fig. 4 (b) to implement this and shave off and remove operation, described gear shaver has trapezoidal or C-type cross section and have bottom width L1, and this width equals or is slightly smaller than the width L2 shown in Fig. 5 (b).In the 4th embodiment, in different steps, cut and shave off.But this moment can be than all sharper keen among the embodiment 1-3 to the cutting of deposited film 1a.Therefore, even for the deposited film 1a that thickness is 1-2mm, also can obtain the gratifying cut surface of quality by cutting.And, can buy the cutter that can use common commercially available blade as shown in Figure 6 cheaply.

Fig. 7 represents the cutting method of fifth embodiment of the invention.This embodiment is the further improved form of the 4th embodiment.Specifically, except the cutters 32 that the cutter 42 that utilizes as shown in Figure 7 substitutes as shown in Figure 5, the cutting in this embodiment, shave off all identical with the line mode with the 4th embodiment.Therefore, the left side of Fig. 7 or right side view are identical with Fig. 5 (b), therefore are omitted.In first to fourth embodiment, cutter only can be in one direction, be on the direction that moves of cutter deposited film 1a to be cut, and on the contrary, cutter 42 has sidepiece shape as shown in Figure 7, therefore, can cut along left side and right direction as shown in Figure 7, and need not when changing cut direction, change the setting of cutter.The cutting angle ε 1 of cutter 42 and ε 2 should be so definite, so that the optimum Cutting condition that can provide thickness and material with deposited film 1a to adapt.When cutter 42 is used for when both direction cuts, cutting angle ε 1 and ε 2 are configured to mutually the same usually.Can be according to the mode similar, the bar 1b that on left side and right direction, gives up independently to the 4th embodiment shave off and remove operation.

Fig. 8 represents the cutting method of sixth embodiment of the invention.In this embodiment, used the cutter of forming by blade 52a and retained part 52b 52.The employed any cutter that is used for cutting and shave off deposited film 1a all is applicable to the cutter 52 of this embodiment in first to the 6th above-mentioned embodiment cutting method.Retained part 52b plays the effect of control handle, and when deposited film 1a was cut and shaves off, it can clamping blade 52a.In addition, length by making retained part 52b and cross sectional shape are unified and to be standardized into for example be the square with preliminary dimension, then when utilizing the 52 couples of deposited film 1a of cutter that are fixed in anchor clamps or machine to cut and shave off, can on single anchor clamps or machine, exchange any cutter that uses first to the 5th embodiment.

Preferred retained part 52b is formed by suitable elastic materials, for example Duracon or Delrin resinoid, or is formed such as silicone rubber or nitrile rubber by more flexible rubber, or can made by wood in some cases.By such form, even when the thickness of deposited film to be shaved off or hardness etc. change, the elasticity of retained part 52b can be offset cutting or shave off the change of resistance.In the device of this embodiment technology of use, this can be used as release mechanism.Can by utilize volute spring 77a and 77b (referring to Figure 15 and 17) be used for give gear shaver 52 elasticity, this content will be described in conjunction with the 9th embodiment hereinafter.

In first to the 6th embodiment, the blade that is used to cut and shave off the cutter of deposited film 1a is formed by conventional material, such as by as required and the carbon tool steel or the martensitic stain less steel that harden by thermal treatment etc. form.But, to the material of cutter without limits, as long as it can suitably cut and shave off the deposited film 1a of the different-thickness of being made by various materials.And, in this embodiment employed cutting and the cutter that shaves off deposited film 1a have such as shown in first to the 5th embodiment along the formed cross sectional shape of length that extends.This makes can repeat the grinding and cutting angle, thereby blade can use the longer time.

Fig. 9 represents the cutting method of seventh embodiment of the invention.In the cutting method of this embodiment, in the step upstream before line, according to above-mentioned first to the 6th embodiment in one of identical mode carry out shaving off and removing of deposited film 1a.Specifically, in first to the 6th embodiment, as shown in Figure 3, deposited film 1a is cut, shaves off and is removed, shave groove 5 thereby in deposited film 1a, formed, and then make the scoring equipment edge shave the bottom of groove 5, be the bar-shaped zone rolling of glass basis 1, meanwhile press this zone, to form line 5a.In the 7th embodiment, by with the deposited film facing surfaces on line excised glass basis.

As shown in Figure 9, by unshowned fixed equipment, glass basis 1 is fixed on the work stage 3 such as vacuum chuck.In work stage 3, form the opening 3a that extends, rule on the bottom surface of glass basis 1 to allow scoring equipment.In this embodiment, formed line 5c on the bottom surface of glass basis 1, this line just in time is positioned under the bottom of shaving groove 5 that is formed on the glass basis 1, and the described groove of shaving is formed according to the method for one of embodiment one to six.

In the glass basis cutting step after scribe step, with the surperficial facing surfaces that forms line on exert pressure so that the slight crack that produces in line further becomes is big, separate until glass basis.When line operation is when carrying out on the bottom surface of shaving groove that 1a forms in deposited film, in the cutting step scribe step after, this method must be exerted pressure, and from the surperficial facing surfaces of ruling under parting glass substrate.Therefore, for example when glass basis be placed directly on by line surface (being the deposited film surface) on the marking-off table and by extruder or roller from this surface when this surface applies load, applied pressure can damage and directly be placed on the depositional coating on the work stage or make it distortion in order to cut glass basis.On the contrary, in the cutting method of the 7th embodiment, can apply the pressure that sheet shape extrusion clamp or roller by the shape and size that are suitable for shaving groove 5 produce according to the direction shown in the arrow B, thereby this pressure concentrates on the bottom 1c that shaves groove 1c as shown in Figure 9.This makes line 5c vertically further to extend, thereby has realized cutting.Therefore, need not push or contact deposited film and parting glass substrate is feasible.

The cutting method of Figure 10-13 expression eighth embodiment of the invention.Design this embodiment and be for handle be formed with on it thickness be 0.05mm-2mm usually such as the glass basis of the thicker relatively deposited film of resin the time, realized that before line gratifying deposited film shaves off and remove the result.At this moment, the advantage combination together of first embodiment and the employed gear shaver of second embodiment specifically, is formed the shape of employed blade in first embodiment and second embodiment by the material of circle bar shaped.This makes effective to shaving off of deposited film.

Figure 10 represents the front elevation and the side view of the employed gear shaver 62 of this embodiment.The material of circle bar shaped, be formed as the shape of gear shaver such as superhard alloy or carbon tool steel.Suitably determine the outside diameter d 1 of circle bar material, 5-10mm normally according to thickness of deposited film to be shaved off.As shown in figure 10, symbol F represents the plane retained part that the part by parallel excision circumference d1 obtains.This retained part is as the reference surface that forms other parts, and also plays the effect similar to retained part 52b shown in Figure 8.Determining and should and using its device to adapt with its element of clamping of gear shaver 62 total length L 3 is set equal to 35mm in this embodiment.Shown in the front elevation of Figure 10, formed along length L 4 by the end face of gear shaver 62 that the cross section is essentially V-arrangement and opening angle is the gear shaver of θ n.To go through θ n value later on.According to deposited film material to be shaved off and the definite blade lengths L4 of thickness is 5-10mm, and is set equal to 7mm in this embodiment.The blade groove part that is positioned at " i " shown in this figure part the right is formed as the arc groove of (curve) R3 that has small curve, and the effect of this part is to evict the useless bar 1b that has been shaved off reposefully from.In this embodiment, R3 is set equal to 38mm.Scope according to the curvature R4 of the determined blade bottom with V-arrangement cross section of the size of deposited film material to be shaved off and thickness and line cutter is about 0.5-1mm.In this embodiment, R4 is set equal to 0.5mm.Therefore blade should be designed to shave off and to remove deposited film fully, and is formed as and has two stage tip angle θ 7 and θ 8.In Figure 10 and 13, t1 represents the distance of blade and θ 7 and θ 8 intersections.Can find out this details from the C direction of Figure 12.In this embodiment, t1 is set equal to 0.3mm, and θ 7 is set equal to 30 °, and θ is set equal to 40 ° for 8 °.To equal about 0.3mm so little by t1 is set at, can set less relatively effective tip angle θ 7, promptly equal 30 °, to realize the satisfied performance that shaves off, meanwhile the θ 8 of knife edge part t1 is set at and equals 40 °, have enough physical strengths with the blade of guaranteeing gear shaver 62.

Below content shown in the figure is mainly concentrated in the description of the 8th embodiment.Figure 11 represents that gear shaver 62 is that the deposited film 1a that how will be formed on the glass basis 1 shaves off and removes.Set gear shaver 62 is consistent with the cutting angle of cutting and shaving off with respect to the angle θ 9 of glass basis, according to the material of deposited film and thickness and this definite angle optimum range is 35 °-45 °.In this embodiment, when this angle was set equal to 43 °, excision thickness was the rubber-based deposited film of 1mm and has obtained satisfied result when it is shaved off.When Figure 11 represented to move gear shaver 62 according to the H direction, it was how to cut and shave off deposited film 1a's.The useless bar 1b that is shaved off is evicted from reposefully along the arc groove of G sign among Figure 10.The pressure that gear shaver 62 is vertically pressed to glass basis 1 surface is about 1-40N.Bigger pressure can produce cut on the glass surface below the deposited film, this has adverse influence to line.

Below with reference to Figure 12 the θ n shown in Figure 10 is described, wherein Figure 12 is the front elevation of the amplification of gear shaver 62.The scope of the formed opening angle θ 3 of the determined blade by gear shaver 62 of tip angle according to the line cutter is 50 °-140 °.The opening angle θ 4 that measures in distance blade 3-10mm place is littler 3 °-6 ° than opening angle θ 3.Below with reference to Figure 13 θ 4 purpose and the advantage littler than θ 3 are described.Figure 13 is the cross section of the blade of the gear shaver 62 that obtains along the line m-n shown in Figure 12 sectional view when seeing from above.Under the condition of θ 4, thereby move cutting and when shaving off deposited film 1a, formed angle δ 2 along the K direction when gear shaver 62 with respect to cut direction less than θ 3.The existence of this angle δ 2 has been played and has been increased in the effect that cutting is called as cutting angle in the theory, and makes cutting and shave off the effective of deposited film 1a thus.In experiment, for cutting and shave off for the thick pitch deposition film of 1mm, the cutting of this moment/shave off processability and cut quality all be much better than not exist δ 2 situation, be the situation of θ 4 when equaling θ 3.In this embodiment, for example, when θ 4 is set equal to 80 ° and θ 3 and is set equal to 84 °, θ 4 is than θ 3 little 4 ° the time, the effect of cutting deposited film is best, and as mentioned above, as θ 4 during, obtained almost suitable gratifying cut quality than little 3 °-6 ° scope of θ 3.By the improvement that utilizes 0.5mm or thicker resin or rubber-based deposited film can obviously observe this cut quality, this improvement is by opening angle θ 4 (opening angle of a distance being arranged with the blade of gear shaver) is obtained less than opening angle θ 3 (opening angle at the blade place of gear shaver).

In Figure 10, as shown in the figure, δ 1 expression blade is not orthogonal to the periphery of gear shaver 62, but slopes inwardly a little from top to bottom.This means and make θ 3 cause having produced δ 1 for a short time than θ 4.In Figure 12, on the other hand, the gear shaver 62 of looking from direction C and the cross section of periphery thereof there is shown θ 5 and θ 6.This means: in Figure 10 and 12, for example when θ 3 is set equal to 84 ° and θ 4 and is set equal to 80 °, be set equal to 40 ° even θ 7 is set equal to 30 ° and θ 8, this moment, θ 5 equaled about 22 ° and θ 6 equals about 31 °.

As previously mentioned, by make can heat treated material such as superhard alloy or carbon tool steel moulding and then blade or integral body are heat-treated and make gear shaver 62.The 8th embodiment is characterised in that and is used to shave off the gear shaver shape of deposited film and shave off mode, and utilizes first embodiment or the cited method of the 7th embodiment to shave off step scribe step afterwards.

Then will describe the cutter sweep of the 9th embodiment of the present invention, this device has utilized the cutting method of first to the 8th embodiment.Figure 14 has represented to utilize the cutter sweep front elevation of first to the 8th embodiment cutting method.Reference numeral 66 expression scoring equipments, the bottom of this equipment has line cutter and/or gear shaver.Scoring equipment 66 make line cutter and gear shaver from a side shifting to opposite side, as shown in the figure, when the guide rail 67 that they are formed along the ball slide unit of knowing (ball slide) moves, be pressed to glass basis 1 with predetermined load by the press device of knowing that uses not shown use hydraulic pressure, compressed air pressure or spring etc.In example shown in Figure 14, the part of scoring equipment 66 is fixed on the synchronous belt 65.When unshowned driving arrangement made pulley 64 rotations such as engine, the synchronous belt 65 around pulley 64 had moved needed distance along guide rail 67.In the figure, scoring equipment 66 is subjected to the driving of synchronous belt, still, also can utilize the activated apparatus known, drive this equipment such as ball-screw and engine and its controller of driving.

Chassis 60, work stage 63 and brace table 63a are formed as one.In this work stage 63, be vertically formed suction port (suction hole) in place, with by utilizing not shown fixed equipment, glass basis 1 being fixed on the upper surface of work stage 63 such as vacuum chuck.Above Figure 14 or the bottom surface as can be seen, the effect by the built-in slewing in chassis 60 can make work stage 63 and brace table 63a half-twist.By this figure as can be seen, the movable block 200 of C-shape is 60 upper surface across the chassis, and by using not shown driving arrangement such as engine and unshowned opertaing device, this block at a time can move needed distance forward or backward with respect to chassis 60.As mentioned above, in the cutter sweep of this embodiment, the sliding of scoring equipment 66 moved and the rotation of 90 ° of work stage make can be in X and Y direction, promptly glass basis is rule with grid-like fashion.

Figure 15 has at length drawn the structure of scoring equipment shown in Figure 14 66.Equipment substrate 71 engages with synchronous belt 65 shown in Figure 14 and guide rail 67, makes whole scoring equipment slide.Joint 74 makes equipment substrate 71 be connected with line substrate 75.Utilize bolt that the back side of slave unit substrate 71 packs into the rear section 74b overall fixed of joint 74 in equipment substrate 71.The forward part 74a of joint 74 and rear section 74b and overall fixed can slide up and down by the effect of sliding apparatus in the line substrate 75 of forward part 74a, and this sliding apparatus is such as being that dovetail joint shown in this figure (dovetail joint) or the sliding apparatus known are such as the ball slide unit.Under the unshowned in the drawings helical spring tension force effect, the forward part 74a of joint 74 and overall fixed can upwards be spurred with respect to equipment substrate 71 all the time in the line substrate 75 of forward part 74a.Be fixed in the tension force that the tip of the micron order screw 72 of equipment substrate 71 can stop this to make progress by micron-sized assembling block 73.Micron-sized bolt 72 is used to regulate subtly and suitably sets the upright position of the entire equipment comprise the substrate 75 of rule and shaves off equipment and the upright position of the tip of following scoring equipment with description.

On line substrate 75, be provided with and shave off part 81 and line part 82, they all are L shaped basically, thereby can carry out coaxial rotation around turning axle 83.On line substrate 75, be fixed with back-up block 76, it is used to make regulates bolt 76a and the cooperation of 76b spiral, and the tip of these two bolts all is formed with hook.By these hooks, volute spring 77a and 77b extend to the bolt 78a and the 78b of spring end, and bolt 78a and 78b are threaded into respectively and shave off part 81 and line part 82.In this structure, load all the time has the power that becomes to making described part to rotate around turning axle 83 counterclockwise (looking from the forward right-hand side of Figure 15) with line part 82 to shave off part 81.That is to say, shave off equipment 202 and scoring tool 14 is pressed downward all the time.This is rotated counterclockwise the tip 79a that forms on the tip that is braked bolt 80a and 80b and the braking/extrusion equipment 79 and the institute that contacts between the 79b stops, wherein said braking bolt 80a and 80b cooperate with the upright arm part spiral that shaves off part 81, and described braking/extrusion equipment 79 is fixed in line substrate 75.With the pressure of about 10-20N when pressing down the equipment of shaving off 202, with the pressure of about 1-40N to pressing down scoring tool 14; That is to say, utilize different pressure to pressing down them.Therefore, set the tension force that is used to produce suitable load of volute spring 77a and 77b separately, bolt 76a and 76b will screw in or back-out back-up block 76 comes adjustment of tonicity subtly by regulating.Deposited film surface inspection apparatus 84 is equipped with detector and all-in-one-piece axle extension with it by making the tip, and utilize the electro-detection equipment of knowing, and detect the upright position of the deposited film on the glass basis with electrical signal form by unshowned signal cable such as linear graduation or transformer.The tip 84a that is used to detect the checkout equipment 84 on deposited film surface is formed as the roller of being made by resin or nylon or Teflon (R), and the detection power of this detecting device (sensing force) is low to moderate 0.2N (newton) or lower, thereby can not make the deposited film surface that cut or distortion are arranged.The planimetric map that Figure 16 is the critical piece shown in Figure 15 when shaving off part 81, line part 82, the equipment that shaves off 202, scoring tool 14 as the glass basis exposure device and deposited film surface inspection apparatus 84 and see from above.This figure shows: deposited film surface inspection apparatus 84, shave off the result that equipment 202 and scoring tool 14 be configured to a row and be, when scoring equipment 66 during along a path movement, can shave off deposited film 1a and simultaneously in the upper surface line of glass basis 1.

The operation and the drive manner of the cutter sweep of ninth embodiment of the invention will be described below.Figure 17 represents that the cutter sweep of Figure 14 is in the front elevation under the stand-by state when scoring equipment 66 is positioned at high order end, at this moment, the tip 84a of deposited film surface inspection apparatus 84, shave off equipment 202 and scoring tool 14 and all be positioned at position away from the glass basis upper surface.Under this state, shaving off part 81 makes them owing to the tension force of volute spring 77a and 77b trends towards being rotated counterclockwise around turning axle 83 with the making every effort to promote of 82 loads of part of ruling, but this is rotated counterclockwise the tip that is braked bolt 80a and 80b and stops with the tip 79a of braking/extrusion equipment 79 and the institute that contacts between the 79b, and makes thus and shave off part 81 and line part 82 still is in halted state.The operation of cutter sweep is as follows.At first, scoring equipment 66 responds the first move signals and moves along the direction shown in the arrow M among Figure 17.When shaving off part 81 and move right, the tip 84a of deposited film surface inspection apparatus 84 moves to the surface of glass basis 1 and detects the surface location of deposited film 1a.Then, the Pneumatic component that is provided with in braking/extrusion equipment 79 is extended, and its tip 79a is with the predetermined moving bolt 80 of degree compacting, this degree should make the control that the tip that shaves off equipment 202 is contacted with glass surface be based on the thickness of the deposited film 1a on the glass basis 1, proofreaies and correct according to the testing result of checkout equipment 84.When scoring equipment 66 when distance L shown in Figure 17 5 moves, shave off equipment 202 and begin cutting and shave off deposited film 1a.When scoring equipment 66 had been moved further and has finished distance L 6 shown in Figure 17, the roller cutter 14a of scoring tool 14 tips moved on the glass basis upper surface that deposited film 1a has been shaved off.Making every effort to promote of 82 loads of line part makes himself owing to the tension force of volute spring 77b trends towards being rotated counterclockwise, and makes the tip of roller cutter 14a produce the predetermined pressure of downward effect thus.This pressure can be used for carrying out the line of glass basis 1 upper surface.Figure 18 represents that the equipment that shaves off 202 is that how to shave off deposited film 1a and scoring tool 14 be that the glass basis upper surface of the exposure that how deposited film 1a shaved off is rule.As previously mentioned, the roller cutter 14a of scoring tool 14 tips is formed as the roller as the tip 84a of checkout equipment, and the upright position that does not need to detect the surface location of glass basis as shaving off equipment 202 or regulate roller cutter 14a tip.Therefore, be formed as the roller cutter 14a of roller and, can realize the line of glass basis upper surface simply by mobile simultaneously to pressing down this cutter.Therefore, under state shown in Figure 180, be used to make 82 rotations of line part braking/extrusion equipment 79 tip 79b not in working order.

In Figure 17 and 18, show the example of cleaner 85.This cleaner 85 is flexible pipes of being made by barras or rubber, and can be with scoring equipment 66 crooked moving.The opening of cleaner 85 be positioned at equipment of shaving off 202 and scoring tool 14 near, be used for producing equipment and remove the dust that produces with scratching process shaving off such as Hoover by negative pressure.But, also can utilize malleation to produce equipment such as jet equipment, this depends on the particle size and the grain amount of the dust of generation.Can utilize such as the equipment of removing that places the equipment of shaving off 202 shown in Figure 10 and remove the deposited film 1a that has been shaved off.In order to remove the tiny thing that shaves off, and then the remover of brush shape can be set after shaving off equipment 202.

In Figure 18,, produced to show the signal that finishes scribe step when scoring equipment 66 is moved further when the tip of checkout equipment 84 84a drops to the surface location that is lower than deposited film 1a.At this moment, scoring equipment 66 be moved further the distance passed through than detect tip 84a and shave off distance between equipment 202 tips, be that size L5 shown in Figure 17 is long.Finish shave off step after, under the control of unshowned opertaing device, the tip 79a of braking/extrusion equipment 79 further extends its Pneumatic component in the drawings be moved upward so that shave off equipment 202, thereby away from the surface of glass basis 1.Need control scoring tool 14 according to similar mode.As shaving off equipment, when scoring equipment 66 moved through the detection tip 84a that equals shown in Figure 17 and the distance L 6 between the roller cutter 14a, scoring tool 14 can upwards be removed.But, in scratching process, the tip 79a of braking/extrusion equipment 79 leaves the tip of braking bolt 80b, as long as roller cutter 14a drops to the position that is lower than deposited film 1a upper surface owing to finishing line, under the tension force condition of volute spring 77b, tip 79b just contacts with the tip of braking bolt 80b.Therefore, can be used for like this opening and electrically contact, and thus scoring tool 14 is released on the glass basis so that Pneumatic component extends.A kind of method in back is fairly simple technically.In this manner deposited film 1a is being shaved off and after the line of the surface of the glass basis 1 that deposited film 1a has been shaved off, scoring equipment 66 is retracted the spare space, this moment shaves off equipment 202 and scoring tool 14 is raised, thereby does not influence glass basis.After this, when movable block shown in Figure 14 200 at a time moved up or down needed apart from the time, repeat to shave off and scribe step.The glass basis that is formed with deposited film on it can be cut into the spaced bar shaped part of ideal thus.Then, make work stage shown in Figure 14 63 change 90 °, and carry out similar step and be scribed into latticed form with the glass basis that will be formed with deposited film.

Also can be sharp shave off deposited film with latticed form from the glass basis in such a way and rule thereon with latticed form with deposited film, promptly, according to mode shown in Figure 14, scoring equipment 66 from a side shifting to opposite side, and as shown in figure 14, make movable block 200 backward or move forward.The structure of work stage 63 should make can be as shown in figure 14 backward or move forward.At this moment, the scoring tool that is assemblied in scoring equipment shown in Figure 14 66 bottoms should be configured to integral body with the equipment of shaving off can relative glass basis surface half-twist.Specifically, can adopt and movable equipment shown in Figure 41 410 similar structures, this will have description in the 18 to the 21 embodiment.In movable equipment shown in Figure 41 410, Reference numeral 430 representative is used to cut the combination of two roller cuttves positioned opposite to each other of polarizer slice.By adopting this one-piece construction, make a roller cutter that is used to rule replace two roller cuttves, the equipment that shaves off replaces 460, has therefore increased the possibility of above-mentioned 90 ° of rotations.In addition, by increase can 180 ° of rotations possibility, can remove deposited film and on X and Y direction, all rule.

Shaving off equipment 202 utilizes different speed governing to start and stop to shave off and rule respectively with scoring tool 14.When finish shave off and rule after, scoring equipment 66 returns stand-by state, shaves off equipment 202 and scoring tool 14 need be raised its release, so that it does not contact with glass basis or influences glass basis.Therefore, be arranged at braking/extrusion equipment 79 inside and its extension degree and be subjected to the Pneumatic component of unshowned controller control should be arranged on two different positions independently, thereby start the tip 79b that shaves off tip 79a partly and line part separately with speed governing.In the 9th embodiment, as shown in figure 18, shave off equipment 202 and have the described gear shaver of first embodiment, this gear shaver is fixed in by cutter tackbolt 86 and shaves off part.But employed one of any gear shaver of the cutting method of first to the 8th embodiment all can be used for the cutter sweep of this embodiment.When deposited film 1a was shaved off, the tip that shaves off equipment 202 need accurately be positioned on the surface of glass basis 1.Can be by screwing in or screw out the upright position that one of corresponding braking bolt 80a and 80b suitably set each tip.The upright position, tip that shaves off equipment 202 needs accurately location, and this tip need be positioned on the surface of glass basis 1 in the moment before startup shaves off step.Finally accurately regulate the position of tip by micron-sized bolt 72.After braking bolt 80 being screwed in or screw out, utilize nut 203 to fix it for adjusting.And, in the 9th embodiment, as shown in figure 18, screw in and be formed at the groove that shaves off in the part 81 and fix this equipment by shaving off equipment 202.But the equipment that shaves off is adjustable with respect to the cutting angle on glass basis surface.Specifically, although it is not shown in the drawings, but this can obtain in the following manner, promptly, by the horizontal arm that shaves off part 81 is partly separated so that its to a certain extent with the distance that shaves off equipment 202 than being fixed by loosely with the approaching part in the center of himself, thereby can rotate around turning axle, and after the angle of the gear shaver 202 that shaves off deposited film 1a is adjusted to best angle, provide a mechanism to make this part be clamped by chuck apparatus.

Then, will the cutter sweep of tenth embodiment of the invention be described.In the 9th embodiment, shown in Figure 16 (a), shave off the direction that equipment 202 and scoring tool 14 move along scoring equipment and be configured to a row, so that, can carry out shaving off and ruling of deposited film simultaneously when scoring equipment during along a path movement.In the tenth embodiment, shave off equipment 202 and scoring tool 14 is spaced apart setting, this equals to rule to form interval of bar shaped part at interval.Figure 16 (b) expression shaves off the plan view of the position relation between part 81 ' and the line part 82 ' in this embodiment.When ruling, suppose that scoring equipment moves along the direction shown in 16 (b) arrow, then shaves off the front that part 81 ' need be set at moving direction, so that at first shave off step with formation bar shaped part.By the thickness adjusted with spacer 204 is that certain intervals is regulated the interval between equipment of shaving off 202 and the scoring tool 14, and promptly spacing is rule to form the bar shaped part at this interval.Therefore, the something in common of this embodiment and the 9th embodiment is: all be to carry out shaving off and ruling of deposited film during along a path movement at scoring equipment, but difference is: scoring equipment moves through the length of spacing and arrives and finishes deposited film and shave in the groove that removes, and then rules along this groove.When with predetermined interval the glass basis of big specification being rule, this embodiment need make mobile ratio the 9th embodiment of scoring equipment have more twice.But, compare with the 9th embodiment, at this moment, do not need to extend cutter sweep, and help to make cutter sweep compact on its Width like this along the direction that scoring equipment moves.And, can on the moving direction that shaves off equipment 202, at the rear portion, there be enough space to place the suitable useless thing that shaves off and removes equipment, and this useless influence that shaves off thing that helps to alleviate in scratching process, left in the groove that shaves off.In others, the cutter sweep of this embodiment has and the essentially identical structure of the 9th embodiment, therefore no longer carries out the description of repetition.

Below with reference to Figure 19 the glass basis cutting method and the device of eleventh embodiment of the invention are described.In the 9th embodiment, the checkout equipment that is used to detect electric signal is set at the front of the equipment of shaving off, to detect the upper surface position of deposited film, then by proofread and correct the thickness of deposited film such as the opertaing device of program controlled, and the tip that then will shave off equipment is positioned at the upper surface of glass basis, wherein, the effect of described checkout equipment is when startup shaves off step, and this equipment is accurately positioned in the blade of gear shaver the upper surface of glass basis.But, for 1mm or thicker deposited film 1a, the variation of its thickness and other factors can cause the blade of gear shaver to be positioned in more than the surface of glass basis, cause not shaving off fully deposited film thus, stay deposited film in the bottom of shaving groove, perhaps can cause the tip of the equipment that shaves off to be positioned in below the surface of glass basis, caused the tip of the equipment that shaves off to influence the periphery of glass basis thus, in the worst case, even can damage scoring equipment.Especially at the periphery of glass basis, promptly begin to produce this problem when being shaved off as deposited film 1a.Design the 11 embodiment and overcome this problem.Specifically, along big specification glass matrix periphery to be shaved off gap (part that does not have deposited film) is set, when glass basis was cut, the part that does not form film was dropped.In the method shown in Figure 19 (a), along big specification glass matrix, be the gap that raw-material periphery setting does not have deposited film.Size S is along with the variation of the control ability of the thickness of deposited film and cutter sweep and change, and is set and equals for example 2-10mm.In the method, at first, the tip of the equipment of shaving off is partly contacted with the S that glass basis has the S size, follow mobile scoring equipment.Variation to the control of the blade of gear shaver is offset by size S, so that blade can contact with the glass basis surface safely, and has the space that protection deposits the edge when shaving off deposited film.In the method shown in Figure 19 (b), not the deposited film of at first removing gap S, be that shaving off of deposited film carried out in the tip of the equipment that shaves off of 1-40N but adopted load that downward pressure is arranged.The tip that shaves off equipment begins to carry out shaving off of deposited film from the left side of figure near the marginal point with glass of deposited film, then arrives in the S ' part on surface of glass basis, has marked curvature R5 as shown in the figure simultaneously.In the dash area of this figure, the part deposited film is left over, and therefore when parting glass substrate S ' part abandoned.If supposition Figure 19 (b) is illustrated in the line of Y direction, then thereby it is illustrated in directions X and has shaved off and rule and formed after the groove of shaving out 5, thereby is how to shave off in a similar manner and rule to form waffle-like pattern on the direction that departs from 90 ° in this direction.In this embodiment, when glass basis is scribed ss waffle-like pattern,, all must form gap S or S ' around edge in method (a) with (b).S1 and S2 representative line to be forming the interval of bar-shaped zone, and is set to usually and is equal to each other.

The 11 embodiment not only is applicable to cutting method but also be applicable to cutter sweep.At the scribble method that is used for the glass that deposits film, even shave off by hand under such opposite extreme situations at deposited film, before line and cutting, the edge that also can cause big specification glass matrix is not by the problem that shaves off and deposited film is left over.In the 11 embodiment, thereby the part of deposited film has overcome this problem by forming not along described edge.On the other hand, in the cutter sweep of the 9th embodiment, when startup shaves off step, by utilizing checkout equipment to detect the position on deposited film surface, then proofread and correct the thickness of deposited film and then set the upright position that shaves off the equipment tip, the tip that will shave off equipment then is positioned on the glass surface of glass basis.But, if this moment deposited film variation in thickness when very big, be difficult to obtain satisfied degree of accuracy.According to the method for the 11 embodiment, form not by edge that the part of deposited film also can overcome this problem along glass basis.This has greatly alleviated the design and the structure burden of cutter sweep.

Figure 20 has explained the principle of twelveth embodiment of the invention cutter sweep.In this embodiment, the cutting method of 9 described the 7th embodiments is applicable to this device with reference to the accompanying drawings.In the cutter sweep of this embodiment, shown in Figure 20 (a), in work stage 3, be formed with many negative voltage supply passages of arranging in a suitable manner 209, fixed such as vacuum plant by not shown negative voltage supply equipment to allow glass basis, and also formed the opening 3a that extends at interval off and on corresponding to line, rule at glass basis from the bottom surface of glass basis to allow scoring equipment 4.In the cutter sweep of this embodiment, be used to shave off the tip of the equipment that shaves off of the deposited film 1a that is formed on the glass basis 1 and the tip of scoring equipment 4 and be located in from its moving direction to see it is vertical line, and the two moves together.Therefore, just in time the equipment that shaves off formed shave groove 5 below formed line 5c.In this embodiment, in the glass basis cutting step after scribe step, must cut along the groove 5 of shaving that forms in the deposited film.Therefore, shown in Figure 20 (a), the roller cutter 14a that shaves off equipment 4 tips need be oriented to as mentioned above see from its moving direction and just in time vertically be positioned at the position of shaving under the groove 5, but in forward/backward direction, be that the direction that cutter moves does not need so accurately.The load that need apply about 10N comes the glass basis line, and the size of this value depends on the thickness of glass.Therefore, from the following cutter sweep that glass basis is rule, upwarding pressure that scoring equipment 4 is produced can cause glass basis 1 to be deviate from from the chuck device that work stage 3 is provided with.In order to prevent this problem, in Figure 20 (a), tighten to be connected at the moving direction that shaves off equipment and be provided with balance roller 205 thereafter and come this load of balance.The tip of this balance roller 205 has the free rolling roller, and this roller has and the substantially the same size and dimension of roller cutter 14a that shaves off equipment 4 tips, and this gear is formed such as urethane rubber by soft material.For glass basis 1 stably is fixed on the work stage 3, balance roller 205 just in time is positioned at the rear of the equipment of shaving off, thereby when applying the pressure P 2 that is used for balance line load P 1, it can and then shave off equipment and move.When thereby the surface that utilizes weight load application devices directly load to be put on deposited film strengthens the power of fixing glass matrix, can damage or the scratching diaphragm.On the contrary, in this embodiment, in the time of from the line of the bottom surface of glass basis 101, load has the load balance roller 205 of required pressure to roll along the bottom of shaving groove 5, and this shaves groove 5 is to be formed at groove on the glass basis by shaving off surface that equipment shaves off deposited film.This feasible can being stabilized under the fixing state at glass basis is rule, and does not have the danger of contact, thereby can cut or other infringement not arranged to deposited film 1a.Among Figure 20 (a), omitted the equipment of shaving off.

After line, carry out the cutting of glass (being separated) from applying load under the surperficial facing surfaces, thereby the cut in the line is further expanded with line.Therefore, in the 9th to the 11 embodiment, formed line along the bottom of shaving groove 5, and from deposited film surface facing surfaces under apply load cutting.On the contrary, in the 12 embodiment, when ruling in the glass basis bottom surface, just in time the deposited film on line is shaved off, and shaves groove 5 thereby formed, and its sectional tool has required size and dimension.Then, shown in Figure 20 (b), the line 207 that is formed by resin or metal such as polyurethane is just in time placed to shave groove 5 on the line 5c, and the roller 206 that its tip has the groove that cooperates with this line appropriateness is placed on the line, thereby when the load that applies 50-200N, this roller rolls by this line.Thus can so that this cutter sweep on shaving off glass basis deposited film and glass basis rule and when cutting, glass basis is turned to.The padded coaming that uses during Reference numeral 208 representative cuttings.In this embodiment, splitting of glass can be integrated in the cutter sweep with additional splitting function after the line, this splitting function can be rule and make it and be split, or at first on cutter sweep glass is rule, and then carries out splitting on the splitting machine.In this embodiment, comprise glass basis is fixed in this device all to glass basis shave off with step of cutting in, do not need contact or press the deposited film surface.Can safeguard and keep the quality of deposited film like this.The sheet shape press member that also can utilize its position to cooperate with the bottom of shaving groove 5 substitutes roller 206 and cuts.

Figure 21 and 22 expressions the 13 embodiment of the present invention.This embodiment is characterised in that: to shaving off on step and the scribe step principle of deposited film is independently to carry out, in the scribe step in downstream, form waste part 11c on the deposited film surface, so that glass basis is supported on the waste part 11c of the deposited film surface formation on the protruding 13a that forms on the work stage shown in Figure 22.

Figure 21 represents to shave off deposited film 11a as the form of how product section and waste part being separated, and product section can be used as the product such as liquid crystal display device.Figure 22 is illustrated in shown in Figure 21 shaving off after the deposited film 11a, how shave groove under (directly in position relation shown in Figure 22 being) reverse side of glass basis is rule.

The effect and the further feature of this embodiment are described below with reference to content shown in the drawings.Has the deposited film 11a that is formed at one of its surface with employed identical glass basis 11 in the above-mentioned embodiment.In work stage 3, formed many suction channel 6 with predetermined interval, thereby fixed glass basis 11 such as vacuum plant by negative voltage supply equipment.An edge of the glass basis of representing from A is shaved groove 15 by unshowned gear shaver to form with waste part 11c and the corresponding interval of product section 11d.The generation type of shaving groove 15 is identical with embodiment 1 and 2, therefore this is not repeated in this description.According to the thickness of glass basis and deposited film 11a and the size of determining waste part 11c with physical strength, such as the relevant condition of the size of the size of product section 11d and suction channel 16 shown in Figure 22.The waste part 11c that finally goes out of use should be as much as possible little.But, in the step of parting glass substrate, when by to by the surperficial facing surfaces of line when applying load, if compare with the thickness of glass basis 11, this waste part is too little, then be difficult to cut.When determining the size of waste part, should consider this problem, and notice that its size should be greater than the minimum required size of as shown in figure 22 work stage projection 13a that this will be described below.The size of product section 11d is according to product, determine such as the size of LCD and additional allowance for finish.

Figure 22 is illustrated in shown in Figure 21 shaving off after the step, how glass basis is inverted and is fixed on the work stage 13, is rule thereby will shave off surperficial facing surfaces with quilt.In this embodiment, the work stage 13 that is used to rule is different from work stage shown in Figure 21, and as shown in the figure, alternately is being provided with protruding 13a and depression 13b with the corresponding position of size that shaves off the formed waste part of step and interval.The upper surface of projection 13a is the plane, and supports the deposited film face side of waste part 11c safely from the position that shaves off and remove deposited film 11a shown in Figure 21.At this moment, utilize negative voltage supply equipment commonly used to realize safe support by suction path 16.Under this state, concern that from position shown in Figure 22 the 4 formed line of line cutter just in time are positioned at formed shaving on the groove 15 on the glass basis 11.Carry out in the following manner shaving to rule on the groove 15.For edge A, by using the combination of known checkout equipment and opertaing device, easily the desired location place on the apparent surface who forms the pairing glass basis in position of shaving groove 11a shown in Figure 21 forms line, described known device is such as being the synchronous belt of the equipment of optical sensor, positioning fixture, driving line cutter 4 such as ball-screw or servomotor driving, and opertaing device is such as being digitial controller.Depression 13b helps to stop the deposited film part contact workpiece platform of product section 11d, thereby avoids by scratching or damage.

In this embodiment, on the glass basis surface relative, rule with the deposited film surface.Like this in scribe step, line the time can not be subjected to the influence of deposited film.And, shaved off with the deposited film of line on the surperficial facing surfaces, thereby formed groove in the corresponding position of line.Like this, even the influence of the deposited film that glass basis is not separately also existed.More than according to method this embodiment is described, wherein the first step is carried out the step that shaves off of deposited film, then rules.But, as mentioned above, owing to be easy to control the position of shaving groove 15 of formation, and, therefore, also can at first carry out scribe step shown in Figure 22 by using above-mentioned opertaing device to be easy to control line 15a.

23 pairs of fourteenth embodiment of the invention are described below with reference to the accompanying drawings.Above-mentioned the 3rd embodiment relates to therein on the glass basis that is formed with deposited film on the surface and carries out shaving off and scribe step of deposited film.This embodiment relates to all being formed with the cutting method of the glass basis of deposited film on two surfaces.This embodiment and the 3rd embodiment are that common ground is: glass basis 21 is divided into waste part 21c and product section 21d.Shave off with scribe step in, all used with the corresponding position of the size of these parts be formed with protruding 23a and the depression 23b work stage 23.Carry out shaving off of deposited film by utilizing the work stage 23 that is formed with protruding 23a and depression 23b as shown in figure 23, at first the deposited film to a surface of the glass basis that all is formed with deposited film on two surfaces shaves off, and then is inverted the deposited film that glass basis 21 shaves off the apparent surface.By using above-mentioned opertaing device, be easy to carry out vertical calibration to forming the position that shaves off groove on two surfaces and forming the position of ruling with respect to edge A.In this embodiment, can shave off the deposited film on a surface, and then shave off the deposited film of opposite side, and then carry out the line on a surface, then carry out the line of opposite flank then; Also alternatively, can shave off the deposited film on a surface, and then be rule in this surface, then carry out this two steps then at opposite side.

As mentioned above, in the above-described embodiment, the bar shaped with the deposited film that forms the required width of slight crack partly is removed, and forms incisory slight crack along the bar-shaped zone that is exposed on the glass basis.Cutting method that obtains thus and device can allow the glass basis that is formed with any kind deposited film on it is cut; such deposited film can be the film such as protective finish or transparency electrode; also can be the deposited film that film or thickness such as the polarizer slice class reach 1-2mm such as resin molding or diaphragm, and the influence of the deposited film that this cutting is not existed.Be interpreted as and can implement the present invention according to other any way outside the above-mentioned embodiment of the present invention, and those variations and revise and also to belong to scope of the present invention.

Instructions with the lower part in, liquid crystal board and manufacturing installation thereof will be described with reference to the accompanying drawings.At first, the liquid crystal board of fifteenth embodiment of the invention will be described in detail.The outward appearance of the liquid crystal board of perspective representation the 15 embodiment of Figure 24, figure (a) observes side, and figure (b) is opposition side, and Figure 25 is the vertical cross-section diagram of liquid crystal board.

This liquid crystal board 350 is made up of a pair of base unit 351a and the 351b that link together, and (at this moment, base unit 351a is the TFT matrix, hereinafter will be referred to as " TFT base unit " to be sealed with liquid crystal therebetween; And base unit 351b is the color filter matrix, hereinafter will be referred to as " color filter base unit ").The end of TFT base unit 351a stretches out from the end of color filter base unit 351b, thereby has formed extension 351aa, and has formed the link 353 that can be used for driving liquid crystal board at the inside surface of extension 351aa.Be connected with FPC (flexible print wiring) or COG (chip on glass) on these links 353, when liquid crystal board 350 was introduced into liquid crystal display device, they were accepted electric signal and realize the demonstration of liquid crystal board 350.

Liquid crystal board 350 is designed to can be used for the rear-projection liquid crystal display device, therefore almost all have the polarizer slice 352a of the outside surface that is connected to base unit 351a and 351b and 352b (at this moment at the whole surf zone of this liquid crystal board, polarizer slice 352a and 352b are positioned at the side of TFT base unit 351a, and hereinafter also will be referred to as " TFT side polarizer slice unit "; And polarizer slice unit 352b is positioned at the side of color filter base unit 351b, and hereinafter also will be referred to as " color filter side polarizer slice unit ").From this viewpoint of function of needed polarizer slice 352a and 352b, they just cover the viewing area (not shown) simply; That is to say, only they need be manufactured equally greatly and they are positioned opposite to each other basically, and accompany into base unit 351a between them and 351b gets final product.But in the liquid crystal board 350 of this embodiment, TFT side polarizer slice unit 352a is extended, and makes it cover the outside surface of extension 351aa.Its reason is explained as follows.

When being formed by glass, the base unit 351a and the 351b that constitute liquid crystal board 350 are extremely thin, for example about 0.4-0.7mm.Therefore, when they combine, have double thickness the position, be on the viewing area and physical strength has on every side increased, and the extension 351aa that TFT base unit 351a stretches out separately is because have only itself thickness, so physical strength is lower.On the other hand, the thick about 0.2-0.6mm of TFT side polarizer slice unit 352a, this thickness is used to strengthen extension 351aa.Thereby to be TFT side polarizer slice unit 352a be extended covers the reason of extension 351aa outside surface for this.Increased the physical strength of extension 351aa like this.The result is, when from a position when another position is carried liquid crystal board or is assemblied in this sheet the liquid crystal display device, even collided or drop, extension 351aa also seldom can split or be out of shape or angle of breakage.

By between TFT side polarizer slice unit 352a and extension 351aa, reserving 1mm or littler distance h, being the width (referring to Figure 25) that glass is outwards exposed, can increase the physical strength of extension 351aa satisfactorily.Width like the stationary phase between the edge of the edge of polarizer slice 352a and 352b and base unit 351a and 351b.

And the edge 352aa of polarizer slice 352a and 352b and the moulding of 352ba make it have on the direction of pointing to base unit 351a and 351b thin vertical cross-section more and more.Specifically, by utilizing laser irradiation mechanism 420 or the cutting mechanism 460 that is provided with in the liquid crystal board manufacturing installation, these edges 352aa and 352ba all are formed as to have or curved surface, and this will be described in more detail below.When from a position when another position is carried liquid crystal board or is assemblied in this sheet the liquid crystal display device, can prevent that the edge 352aa of polarizer slice 352a and 352b and 352ba (particularly angle) from being collided by accidental, and prevent from thus to peel off.Under the situation that has formed diaphragm on the outside surface of polarizer slice 352a and 352b and become one with it, said structure stops these films to be peeled off from polarizer slice 352a and 352b.

The preferred configuration of edge 352aa and 352ba is described now.In order to assess the various configurations of edge 352aa and 352ba, the liquid crystal board manufacturing installation 400 of the 18 embodiment that utilization will be described in detail afterwards experimentizes for example, is how to influence base unit 351a and 351b with the change (changing by the cutter with C shape and trapezoid cross section that exchanges shown in Figure 32 (a) and 32 (b)) of the cutting edge shape of the blade 461 of observing cutting mechanism 460.The results are shown in Figure 26.

Relation between pitch angle g at polarizer slice 352a shown in the schematic diagrammatic sketch 25 of Figure 26 and 352b edge (being the ascending angle (rising angle) of the side tool sword of blade 461) and the resulting performance, promptly angle g influences the mode of polarizer slice 352a and 352b and base unit 351a and 351b.For 90-135 ° angle; four following projects need evaluated: the physical strength of extension 351aa, the δ type fragmentation of polarizer slice 352a and 352b, diaphragm peel off and base unit 351a and 351b and polarizer slice 352a and 352b between remaining bounding force.For different pitch angle g scopes, the assessment result of each project is divided into three grades: good specifically, general and poor.As shown in figure 26, when the scope at pitch angle during, good or general performance in all projects, have all been obtained at 90-135 °.Therefore, the preferred configuration of edge 352aa and 352ba is the configuration that surface tilt becomes this angular range.

Be to be noted that the optimum condition of finding is applicable to that edge 352aa and 352ba are formed as the situation when having inclined surface in above-mentioned experiment.Clearly, edge 352aa and 352ba also can be formed as curved surface, as long as their cross section is more and more thinner towards the direction of base unit 351a and 351b.Base unit 351a and 351b also can be formed by other material outside the glass.When make efficient be not override consider problem the time, can be by at first cutting single base unit 351a and 351b and then it being bonded in the polarizer slice that is cut into preliminary dimension bond polarizer slice 352a and 352b.

The liquid crystal board manufacturing installation of the present invention that is applicable to the above-mentioned liquid crystal board 350 of manufacturing is described referring now to accompanying drawing.The manufacture of liquid crystal board 350 will in the end be described in detail.

At first, will the liquid crystal board manufacturing installation of sixteenth embodiment of the invention be described.Figure 27 represents the outward appearance skeleton view of the 16 embodiment liquid crystal board manufacturing installation, and Figure 28 is the enlarged drawing of glass basis major part.As shown in figure 27, liquid crystal board manufacturing installation 400 is made up of stand (bed) (not shown) as work stage in fact, is placed on it the strip glass basis 301 that the surface is bonded with polarizer slice 302 on this stand.The roller cutter 430 that movable equipment 410 has laser irradiation mechanism 420, be used to rule with and go up the range sensor that stretches out 440 of assembling downwards.They move with movable equipment 401.

Laser irradiation mechanism 420 is employed CO2 laser equipments in conventional cut/former, and it launches high-octane laser beam.Roller cutter 430 (will be described below) produces slight crack in glass basis 301, thereby can cut.Roller cutter 430 has the diameter u1 of about 2.5mm, and has about 120-150 ° blade obtuse angle w1 (referring to Figure 29).Come back-up roller flywheel knife 430 by spring on the movable equipment 410 or air cushion, thereby apply predetermined pressure to glass basis 301.Range sensor 440 is the displacements that are used to survey polarizer slice 302 upper surfaces on the glass basis of placing on the stand 301, and is used to make laser irradiation mechanism 420 and roller cutter 430 to keep constant to the distance between polarizer slice 302 upper surfaces.This control can make the focusing of laser irradiation mechanism 420 stable, and the pressure stability that roller cutter 430 is produced.In addition, movable equipment 410 moves with the speed of about 200-500mm/sec, and this speed is the speed that is fit to that moves of roller cutter 430.Needless to say, laser irradiation mechanism 420 is assumed to be to have produced is enough to and the suitable laser output of this speed.

The operation of liquid crystal board manufacturing installation 400 will be described below.As shown in figure 27, movable equipment 401 moves with the direction shown in the arrow D along the border between the unit on the glass basis 301.At this moment, the laser irradiation mechanism 420 to polarizer slice 302 irradiation laser bundles moves in the front of roller cutter 430.Therefore, be melted by polarizer slice 302 parts of laser beam irradiation and by adding heat abstraction, the glass basis at this place is exposed, and formed bar-shaped zone 311 thus.Follow the roller cutter 430 after mobile laser irradiation mechanism 420 to move, and formed the slight crack 312 (hereinafter also being referred to as " line ") (referring to Figure 28) that is used to cut along bar-shaped zone 311.

Formed slight crack 312 along the border between the unit on the glass basis 301 in this manner.Afterwards, when as required load being applied on the glass basis 301, glass basis is easy to along slight crack 312 crackings, thereby has made liquid crystal board.Even do not apply load to glass basis 301, when forming slight crack 312, this slight crack can further expand, thereby makes glass basis 301 crackings.At this moment, glass basis is also along slight crack 312 crackings.In practice, in order to obtain high manufacturing efficient, movable equipment 410 is moved horizontally along all a plurality of borders between the unit, with the above-mentioned liquid crystal board manufacturing installation 400 of repetitive operation, glass basis 301 is inverted, rule at the opposition side of glass basis 301 by use roller cutter 430 then, and follow parting glass substrate 301.Also be bonded at polarizer slice under the situation of opposition side, the operation of above-mentioned liquid crystal board manufacturing installation 400 is also carried out in this side.

As mentioned above, liquid crystal board manufacturing installation 400 is very effective aspect manufacturing high-quality liquid crystal board, because it has stoped the cracking at the out of position place of glass basis 301, even and when processing is bonded with the glass basis 301 of polarizer slice 302, also can avoid the chance of polarizer slice 302 to peel off.

Then, with the 30 liquid crystal board manufacturing installations of describing seventeenth embodiment of the invention with reference to the accompanying drawings.In the figure, utilize the Reference numeral identical to come mark to have same names and play these parts of same function, and omitted being repeated in this description of these parts with Figure 27-29.This also is applicable to the 18 to the 21 following embodiment.The difference of the 17 embodiment and the 16 embodiment is: utilize jet mechanism 450 to replace roller cutter 430.As shown in figure 30, the back in laser irradiation mechanism 420, movable equipment 410 has jet mechanism 450, and this mechanism can be jet to the bar-shaped zone 311 of glass basis 301 by its nozzle 451.Gas by nozzle 451 ejections for example is pressurized air or inert gas (such as nitrogen).

Liquid crystal board manufacturing installation 400 is described identical with the 16 embodiment basically, but the operation that forms line has difference with it.Its difference is as follows.Not only heat and melt polarizer slice 302 and remove its part thus from the laser beam of laser irradiation mechanism 420, and heating simultaneously is exposed to the bar-shaped zone 311 on the glass basis, the result is bar-shaped zone 311 heating.The bar-shaped zone 311 of heat is cooled off apace by the gas of nozzle 451 ejections of the jet mechanism 450 after the laser irradiation mechanism 420.This makes bar-shaped zone 311 shrink and has produced slight crack.In this embodiment, this slight crack is a slight crack 312.

Then will be with reference to the accompanying drawings the 31 and 32 liquid crystal board manufacturing installations of retouching the 18 embodiment of the present invention.The difference of the 18 embodiment and the 16 embodiment is: utilize cutting mechanism 460 to replace laser irradiation mechanism 420.As shown in figure 31, in the front of roller cutter 430, removable unit 410 has cutting mechanism 460, and the cutter 461 of this cutting mechanism 460 stretches out predetermined angle with respect to polarizer slice 302.

The operation of liquid crystal board manufacturing installation 400 is described identical with the 16 embodiment basically, and the operation when still removing part polarizer slice 302 has difference.Its difference is as follows.When moved on the border between the unit of cutting mechanism 460 on glass basis 301, the part of polarizer slice 302 was shaved off by the blade just as firmer chisel, and bar-shaped zone 311 is exposed on the glass basis 301.The useless bar 302a of the polarizer slice 302 that shaves off is discharged from along blade 462.

Utilize this liquid crystal board manufacturing installation 400, can easily form bar-shaped zone 311.In addition, cutting mechanism 460 only needs mechanical mechanism.This makes and is easy to control depth of cut and maintenance.

The cutting edge shape of cutter 461 is described referring now to Figure 32.When cutter has C type cross section shown in Figure 32 (a), can shave off polarizer slice 302 with constant width.This width of bar-shaped zone 311 that helps to be exposed to glass basis 301 is stable.When cutter has ladder type cross section shown in Figure 32 (b), have the identical advantage except having with the cutter in above-mentioned C type cross section, also can make the cutting surface tilt of the polarizer slice of staying on the glass basis 301 302.This makes polarizer slice 302 seldom can peel off.And the frictional resistance that cutter 461 produces on the useless bar 302a of the polarizer slice 302 that is shaved off reduces.This makes that useless bar 302a is more smooth along the discharge of blade 462.

When cutter has semi-circular cross-section shown in Figure 32 (c), except having the advantage identical, further reduced cutter 461 by the frictional resistance that produces on the useless bar 302a that shaves off with above-mentioned cutter.But, be to be noted that the width of bar-shaped zone 311 of exposure is narrower.When cutter has round section shown in Figure 32 (d), except having the advantage identical,, can utilize the whole periphery of blade to cut because the rotating mechanism that is used to make the blade rotation is provided in addition with the cutter of above-mentioned semi-circular cross-section.This helps to prolong the life-span of cutter 461.But, at this moment, also must provide the mechanism that useless bar 302a is discharged in addition.

Then will be with reference to the accompanying drawings the 33 and 36 liquid crystal board manufacturing installations of describing the 19 embodiment of the present invention.The difference of the 19 embodiment and the 18 embodiment is that cutting mechanism 460 has improved configuration.As shown in figure 33, front at roller cutter 430, movable equipment 410 has cutting mechanism 460, and shown in Figure 34-35, this cutting mechanism 460 has the blade 462 and 463 positioned opposite to each other with predetermined space v, they all have blade, and the bottom between blade 462 and 463 is provided with cutter 464.The interval v that the width of cutter 464 equals to be scheduled to, and make the constant interval v of maintenance between blade 462 and 463 thus.Top between blade 462 and 463 is provided with support component 465, and it is the same with cutter 464, has the width identical with predetermined space v.Support component 465 is supported by movable equipment 410.Utilize bolt or rivet with these blades 462,463 and 464 and support component 465 be configured to one so that change.

The operation of liquid crystal board manufacturing installation 400 with above-mentioned configuration is described identical with the 18 embodiment basically, but the operation when removing part polarizer slice 302 has difference.Its difference is as follows.Shown in Figure 33 and 36, when cutting mechanism 460 moves according to the border of direction between its unit of glass basis 301 short sides, the bar-shaped zone of blade 462 and 463 cutting polarizer slices 302.Then, so the bar-shaped zone of the polarizer slice 302 after the cutting is shaved off and is removed along cutter 464 with the form of useless bar 302a from glass basis 301 by cutter 464.Simultaneously, exposed bar-shaped zone on the glass basis 301.

Utilize this cutting mechanism 460 can obtain the advantage identical with the 18 embodiment.In addition, because cutting mechanism 460 is made up of a plurality of cutters, therefore, for example, can change the width of the bar-shaped zone 311 on the glass basis 301 simply by replacing cutter 464.And, after in the cutter one or two denuded, can only change those cutters.That is to say, can easily change the width of bar-shaped zone 311, and reduced the operating cost of cutter effectively.

Then will be with reference to the accompanying drawings the 37 liquid crystal board manufacturing installations of describing the 20 embodiment of the present invention.The difference of the 20 embodiment and the 19 embodiment is: a blade 462 and 463 has improved configuration, thereby reduces the cutting resistance to polarizer slice 302.When blade 462 when 463 all have the single blade identical with the 19 embodiment, when utilizing them to cut thick polarizer slice, can cause high broaching load to be applied on their blade inevitably.In other words,, and can cause polarizer slice 302 in cutting process, to be out of shape like this to the cutting resistance height of polarizer slice 302, and the δ type fragmentation that causes cut end.In order to overcome these problems, in this embodiment, as shown in figure 37, blade 462 ' and 463 ' is provided with a plurality of (among this figure being two) blade, they have more and more littler depth of cut (in the figure, arrow D represents cut direction) in cut direction.This broaching load that causes being applied on the blade reduces, and has reduced the cutting resistance to polarizer slice 302 thus, makes the problems referred to above seldom occur.

Then will 38 and 39 retouch the of the present invention the 20 liquid crystal board manufacturing installation 400 with reference to the accompanying drawings with embodiment.The 20 difference with embodiment and the 19 embodiment is: utilize the roller cutter to replace a blade 462 and 463.As shown in figure 38, in the front of roller cutter 430, movable equipment 410 has cutting mechanism 460, and as shown in figure 39, this cutting mechanism 460 has positioned opposite to each other a pair of with shaft roller cutter 462 and 463 with predetermined space v, rather than the blade 462 and 463 shown in Figure 34 and 35.Utilize this structure can further reduce cutting resistance to polarizer slice 302.At this moment, roller cutter 462 and 463 blade are 30-90 ° acute angles, thereby when the polarizer slice that stays 302 at place, cut edge is peeled off on preventing glass basis, can also guarantee enough depths of cut.Roller cutter 466 and 467 diameter range are 5-10mm, to guarantee its turning axle enough spaces are arranged, and guarantee to have the needed enough peripheral speeds of fly-cutting, and guarantee that roller cutter 466 and 467 self has enough physical strengths.

To carry out the description of complementarity to the common ground of the 18 to the 21 embodiment now.In the liquid crystal board manufacturing installation 400 of the present invention, partly shave off and remove by the bar shaped of blade or roller cutter with polarizer slice 302.Simultaneously, if blade etc. contacts glass basis 301, then the blade of blade etc. can be cracked, or the surface of glass basis 302 can be scratched.This cut is not wish to obtain especially, because it can make glass basis split in undesirable position, and reduces its quality.On the other hand, in fact, between glass basis 301 and polarizer slice 302, exist the extremely thin bonding coat that is used to bond them together.Therefore, the blade of blade etc. is set in the bonding coat at the beginning, so that do not contact glass basis, in addition, in cutting process, detects and controls it by position transducer 440.Also alternatively, can use harder than polarizer slice 302, but than the material of the soft material of glass basis 301 as blade.

The width range of the bar-shaped zone 311 on the glass basis 301 is 1-3mm, preferably 1-2.5mm.This helps to guarantee to have enough useful area on the polarizer slice 302 of each liquid crystal board, and can easily form incisory slight crack 312 and can not reduce quality.Therefore, the size of blade etc. need correspondingly be set.Particularly in the 19 to the 21 embodiment,, be easy to realize this result by the interval v between a blade 462 and 463 or one pair roller cutter 466 and 467 is set in the above-mentioned scope.

And, for discharging smoothly, the useless bar 302a that makes the polarizer slice 302 that is shaved off can not be accumulated on the blade etc., and blades etc. are coated with Teflon (R) or adamas, are bonded at the there to stop useless bar 2a.Can prolong the life-span of blade etc. like this.

Except with the specifically described structure of embodiment, liquid crystal board manufacturing installation of the present invention can have any other structure, and many variations and revise and also belong to claims of the present invention scope required for protection.For example, can utilize the bonding agent of any kind that comprises common acrylic compounds or silicones class that glass basis 301 and polarizer slice 302 are bonded together.Particularly in the 19 to the 21 embodiment, utilize blade 465 that polarizer slice 302 is shaved off, therefore the adhesive type that is shaved off and can provide enough bounding forces is easily used in suggestion, to make qualified product.The suggestion film that laminates of protectiveness that bonds on the surface of polarizer slice 302 because remove this diaphragm afterwards when freighting, also can be removed and be deposited on lip-deep melt granules and cullet (employed glass fine grained during glass-cutting).In the above-described embodiment, movable equipment 410 moves with respect to stand; Also alternatively, this stand is manufactured into and can moves with glass basis placed on it 301.

How describe in detail below with reference to the accompanying drawings utilizes above-mentioned liquid crystal board manufacturing installation 400 to make aforesaid liquid crystal board 350.Figure 40 represents to form the outward appearance skeleton view of the glass basis of liquid crystal board 350.Figure 41 represents to utilize the side view of the liquid crystal board manufacturing installation of glass basis, and Figure 42 represents to utilize the vertical cross-section synoptic diagram of the glass basis after the liquid crystal board manufacturing installation is handled.Figure 43 represents the outward appearance skeleton view of glass basis, and wherein the surperficial cutting position that (b) represents the color filter side is schemed on the surface of figure (a) expression TFT side.At this moment, used the liquid crystal board manufacturing installation (referring to Figure 31) of the 18 embodiment typically, and to have used the blade cross section be the blade 461 of the cutting mechanism 460 of trapezoidal (referring to Figure 32 (b)).

At first, make the glass basis of forming by a pair of TFT matrix 301a that bonds together and color filter matrix 301b, with its raw material as formation liquid crystal board 350.Glass basis 301 has many TFT base unit 51a and the many color filter base unit 51b that is arranged in close proximity to each other with latticed form.Between every couple of TFT base unit 51a and color filter base unit 51b, be sealed with liquid crystal.And, on the outside surface of TFT matrix 301a and color filter matrix 301b, be bonded with TFT side polarizer slice 302a and color filter side polarizer slice 302b respectively, to cover all TFT base unit 51a (Figure 40).On the outside surface of TFT side polarizer slice 302a and color filter side polarizer slice 302b diaphragm is arranged.

Then, glass basis 301 is placed on the stand of liquid crystal board manufacturing installation 400, TFT matrix 301a up at this moment.Then, make movable equipment 410 along border U1, U2 parallel to each other between the contiguous TFT base unit 351a,----(referring to Figure 43), with a direction (direction shown in the arrow D among Figure 31 and 18) one side from the another side that moves to of glass basis 301.The result is that a part of polarizer slice 302a is shaved off by cutter 461, and has exposed bar-shaped zone 311a (referring to Figure 42) on TFT matrix 301a.Afterwards, roller cutter 430 moves along bar-shaped zone 311a, thereby has formed line 312a (referring to Figure 42).

Afterwards, make glass basis 301 translation in surface level, to repeat aforesaid operations along border U2, U3---successively.Then, glass basis 301 is rotated 90 ° in surface level, so that repeat aforesaid operations (referring to Figure 43) along border Q1, the Q2---vertical with border U1, U2,----, thereby has formed line 312b (referring to Figure 43).

Then, glass basis 301 is inverted, on color filter matrix 301b, to repeat aforesaid operations.But the operation of this moment is different with the operation of being carried out on TFT matrix 301a.Specifically, it not only along at above-mentioned border U1, U2,----border V1, V2,----(referring to Figure 43) between the color filter base unit 351b of right opposite carry out, and along with border V1, V2,---parallel and have border W1, the W2----(referring to Figure 43) of preset distance to carry out with it, to form extension 351aa.Therefore, make order that movable equipment 410 replaces with V1, W1, V2, W2----along two kinds of borders, with a direction (direction shown in the arrow D among Figure 31 and 41) one side from the another side that moves to of glass basis 301.

The result is that a part of color filter side polarizer slice 302b is shaved off by blade 461, and alternately exposes bar-shaped zone 311c and 311d (referring to Figure 42) on color filter matrix 301b.Afterwards, roller cutter 430 moves along bar-shaped zone 311c and 311d, thereby has formed line 312c and 312d (referring to Figure 42).

Then, glass basis 301 is rotated 90 ° in surface level, so that repeat aforesaid operations (referring to Figure 43) along border T1, T2,----between the color filter base unit 351b, described border is just in time relative with above-mentioned border Q1, Q2---, thereby has formed line 312e (referring to Figure 43).

Then, on glass basis 301, apply load as required, thereby be cut into the paired product of TFT base unit 351a and color filter base unit 351b along line 312a to 312e.At this moment, the part 354 (shade among Figure 42) of the color filter matrix 301b (comprising color filter side polarizer slice 302b) between line 312d and line 312d is regarded as unwanted part and is removed.Produced extension 351aa among the TFT base unit 351a in the every pair of product.At last, COG or FPC are connected to the link 353 of the inside surface formation of extension 351aa, thereby have produced final product liquid crystal board 350 (referring to Figure 24).

In the liquid crystal board of making thus 350, the TFT side polarizer slice 352a of bonding should almost cover the whole outer surface of the TFT base unit 351a that comprises extension 351aa, and the whole outer surface of the color filter side polarizer slice 352b of the bonding color filter side group body unit 351b that should almost cover.

And, should make the surface that has inclination at its edge 352aa and 352ba place to the cutting of TFT side polarizer slice 352a and color filter side polarizer slice 352b, this inclined surface reflects the angle of elevation of the side edges of blade 461.And the width that TFT base unit 351a and color filter base unit 351b expose in its outer surface edge approximates half of bottom blade width of blade 461.Therefore, by regulating the shape and size of blade 461, available said structure, this structure can be given the desirable physical strength of liquid crystal board and desirable be prevented the ability that polarizer slice is peeled off.

Self-explantoryly be to utilize any other liquid crystal board manufacturing installation 400 except the 18 embodiment and make liquid crystal board 350 by technology same as described above.

Incidentally, when in such a manner the glass basis of big specification being cut into single liquid crystal board, need all carry out above-mentioned cutting operation in horizontal and vertical (X and Y direction).But, can cause following problem to the change of glass basis cutting order.With reference now to Figure 44-48, describes how to cause these problems.At first, as shown in figure 44, when the glass basis 301 that is bonded with polarizer slice 302 by when directions X cuts, movable equipment 410 with cutting mechanism 460 (for example can form this mechanism by blade) is as the glass basis exposing device, then roller cutter 430 shaves off and removes polarizer slice 302 along directions X, meanwhile rules.Then, thus when shaving off polarizer slice 302 and exposing bar-shaped zone 311, formed line (slight crack that forms along cutting) along the center line of bar-shaped zone 311.Then, as shown in figure 45, movable equipment 410 (this equipment have blade 461 and at thereafter roller cutter 430) is meanwhile rule along the Y direction vertical with directions X, according to shaving off and remove polarizer slice 302 with the same mode of directions X.In this cutting method, blade 461 is in the operation of the front of roller cutter 430.This makes that cutting is bonded with the needed time of glass basis of polarizer slice and only the needed time period cardinal principle of glass-cutting sheet is identical.

But, as shown in figure 46, when blade 461 moves along the Y direction vertical with the formed line of directions X before 312, the shoulder normal impact of the slight crack (line 312) that the blade that is pressed in the blade 461 on the bar-shaped zone 311 of glass basis 301 and line form.The result as shown in figure 47, the angle of liquid crystal board, promptly the cross-shaped portion branch between the line splits brokenly, or as shown in Figure 5, the blade 461a of blade 461 can be cracked.The mission life that this has shortened blade 461 has increased operating cost thus, and has also reduced the quality of liquid crystal board.Therefore, when polarizer slice 312 was shaved off and removes, the use-pattern of suggestion blade 461 was that it is the line 312 by forming before not.

The cutting method of avoiding this problem is described below with reference to accompanying drawing 49-51.At first, as shown in figure 49, the roller cutter 430 that is used to rule is retracted, and movable equipment 410 only is pressed in blade 461 on the glass basis 301 when directions X moves.That is to say, when movable equipment 410 for the first time when directions X moves, polarizer slice 302 is shaved off and is removed, thereby has formed bar-shaped zone 311, but does not form line 312 at this bar-shaped zone 311.

Then, as shown in figure 50,, when shaving off polarizer slice 302, rule along the Y direction according to aforementioned manner.That is to say, form bar-shaped zone 311 and line 312.At this moment, not line on the polarizer slice 302 that will be shaved off does not promptly have line on the bar-shaped zone 311 that movable equipment 410 forms for the first time when directions X moves.Therefore, blade 461 can successfully shave off glass basis 301, and can not collide line 312.

At last, shown in Figure 51, recall blade 461 specifically, only make roller cutter 430 along bar-shaped zone 311 operations, described bar-shaped zone 311 is that movable equipment 410 is formed when directions X moves for the first time, so that rule, rule 312 to form, thereby realize cutting along the directions X of glass basis.In such a manner, with at directions X, then in the Y direction and cut at the such order of directions X then, although increased the running time, can greatly prolong the serviceable life of blade, and improve the quality of liquid crystal board.

When allow using the longer time, can at first shave off polarizer slice 302 at X and Y direction, forming bar-shaped zone 311, and then rule at both direction.Also alternatively, the device that shaves off and remove the device of polarizer slice and be used in addition rule can be configured to independently, therefore, these two steps can be carried out independently.
