Description
Technical field
The present invention relates to a kind ofly for example make bonding structure body that pair of workpieces (work) fits and the manufacture method of bonding structure body by sticker.
Background technology
Usually; liquid crystal display is a kind of bonding structure body, by Liquid Crystal Module (module), operation are consisted of with the laminations (laminate) such as protection panel (cover plate (coverpanel)) on contact panel (touch panel), protection surface.As the member (hereinafter referred to as workpiece) of the lamination object of these Liquid Crystal Modules, contact panel, protection panel etc., it then is the housing that group enters liquid crystal display.
For this workpiece is fitted each other, there are the method for utilizing adhesive sheet (sheet) and the method for utilizing the resin sticker.Adhesive sheet is on sheet material (sheet) two sides as matrix, is coated with sticker and pastes peeling paper to form.Compare with sticker, this adhesive sheet is relatively more expensive.And, when using adhesive sheet, the step such as must carry out in advance peeling paper being peeled off.Therefore, because of requirements such as reduction costs, the sticker that usage comparison cheapness and step can be simplified is fitted becomes main flow gradually in recent years.
And the workpiece as protection panel or contact panel is to give lamination in the mode with the display surface region overlapping of Liquid Crystal Module.In this case, if having air layer between each workpiece, then can because extraneous light reflects, cause the observability (visibility) of display surface to descend.In order to tackle this situation, have when fitting each workpiece, utilize sticker to insert (gap (gap)) between each workpiece, thereby form adhesive coating.This adhesive coating has as the distance piece between each workpiece (spacer) and protects the function of workpiece.
In addition, in recent years, the demand of answering picture to maximize, liquid crystal display also constantly maximize.In the situation of large-scale liquid crystal display, the area that consists of the workpiece of this liquid crystal display also can become greatly, therefore deforms easily.Therefore, the protection workpiece in order to absorb distortion, the adhesive coating desired thickness tends to thicken gradually.For example, require gradually the thickness of hundreds of μ m.
Like this, if will guarantee thickness, then the amount of necessary sticker increases.Thus, be supplied at the sticker with necessary amount in the situation of workpiece, sticker can flow, and exposes from workpiece easily.Therefore, consider to use few high viscosity resins that flows as the resin (resin) of sticker.But, even if in this case, if technique (process) conditions such as coating position of sticker are not strictly adjusted the situation that yet can exist sticker to expose from the regulation zone when fitting so.
In order to tackle described situation, have in advance in the periphery of regulation dispensing area, utilize resin to form sealing (seal) mode (with reference to patent documentation 1) of the sealing of dike shape.For example, as shown in figure 20, on workpiece S1, be frame shape coating resin sticker R1, make its sclerosis and form sealing.Afterwards, to the inboard resin sticker R2 that supplies with of sealing, as shown in figure 21, workpiece S2 is fitted.In the sealing mode because there is sealing in periphery, therefore can pass through sealing section, prevent resin sticker R2 when fitting because of mobile exposing of causing.
In addition, in order to eliminate optics diffuse reflection (diffuse reflection), sometimes also can between workpiece, fill refractive index and the few identical material (functional material) of the refringence of workpiece.In this case, packing material is also born the function as the sticker that makes the workpiece adhesion.
And applying method has two kinds: a kind of is the method for fitting in atmosphere, and another kind is the method for fitting in a vacuum.The method of fitting in atmosphere need not exhaust equipment, can realize at an easy rate.But the applying in atmosphere is difficult to realize the not process conditions setting of residual bubble of binding face.These process conditions are such as the coated pattern (pattern) that launches the resin of resin when fitting, laminate pressure, pressure applying method etc. are arranged.On the other hand, in the method for fitting in a vacuum, so long as the environment after the abundant exhaust then there is no gas on every side, therefore can realize with comparalive ease the applying that bubble is less.

Patent documentation 2: Japanese Patent Laid-Open 2008-209510 communique
Patent documentation 3: Japanese Patent Laid-Open 2009-8851 communique
But, on-the-spot in actual production even if fit in a vacuum, because of needs such as production times, be difficult to carry out enough for a long time exhausts.Therefore, can only under the state of residual gas in a way, fit, thereby it is residual to produce bubble.Figure 22 represents the example of this residual bubble A.The occurrence positions of residual bubble A is most inner edge at sealing, corner etc. usually.This is because cause in the path of sticker process when fitting.That is, if sticker diffusion when fitting, then bubble is extruded to the sticker outer rim, thereby arrives the inner edge of sealing.Thus, can there be residual bubble in this inner edge.In addition, sticker is that the inner edge along sealing moves to the corner, and therefore most of bubble coalescence are in the corner.
When this residual bubble A occurs in user's (user) the field range W of liquid crystal display etc., the observability that might hinder picture.Therefore, residual bubble A shown in Figure 22 is preferably outside the field range W that is in user shown in Figure 21.And residual bubble A when being retained in periphery frame (bezel) inboard of the viewing area housing that consists of liquid crystal display, can not have problems especially.
But, the demand of answering picture to maximize, field range W it is desirable to guarantee wide area.Therefore, the viewing area of display device must use as far as possible extensively.That is, it is desirable to, reduce as far as possible the part that causes the viewing area not used because bubble is residual, utilize housing to block the part of residual bubble.
Residual in order to prevent bubble, a kind of method has also been proposed, at sealing the gap is set in advance, flow out resin from the gap during applying, thereby discharge bubble (patent documentation 2, patent documentation 3).But in this method, the resin of outflow can drip from workpiece, makes dirty on every side.This point becomes problem when especially set driving circuit is fitted with the Liquid Crystal Module of substrate around liquid crystal panel.
Summary of the invention

Embodiment
With reference to graphic, specify embodiments of the present invention (hereinafter referred to as embodiment).In addition, the sealing among each figure, sticker, bubble etc. are indicative icons, with the avalanche situation of reality, nowed forming etc. might not be consistent.
[formation]
As shown in Figure 1, present embodiment is a kind of bonding structure body M, by adhesive coating B, a pair of workpiece S1, workpiece S2 is fitted.As workpiece S1, the workpiece S2 of applying object, it is the rectangular flat with tabular surface.Such as the substrate that can consider to use the formation display device, module etc. of workpiece S1, workpiece S2.
As shown in Figure 2, have sealing 3 and sticker filling part 4 on the adhesive coating B.Sealing 3 is to form as follows, that is, around the regulation zone on the tabular surface of workpiece S1, in the mode from the surface elevation of workpiece S1, utilize the resin sticker to form.In the situation of display device, this regulation zone for example is the rectangular area that becomes field range W.Sticker filling part 4 is the parts to the interior potting resin sticker R in zone that sealing 3 surrounds.
Forming enlarged portion 31 on the sealing 3.Observe from the planar side of workpiece S1, enlarged portion 31 is to make the part of the inner edge of sealing 3 enlarge the part that forms to the outside, regulation zone.For example, in Fig. 2, the enlarged portion 31 of rectangle is arranged on 4 angles (corner) of sealing 3.
[effect]
Manufacture method to present embodiment as implied above describes.At first, for workpiece S1, form aforesaid sealing 3.For example, by the serigraphy (screenprint) that utilizes printing equipment, the resin sticker is printed, comprise the sealing 3 of enlarged portion 31 described above with formation.As sticker, for example use ultraviolet hardening resin.
Then, utilize ultraviolet lamp, in atmosphere to the printing after sealing 3 irradiation ultraviolet radiations.Carry out because the oxygen in the atmosphere can hinder sclerosis, so sealing 3 remains temporary transient sclerosis.Whereby, prevent flowing of sealing 3.
Then, as shown in Figure 3, to the zone of sealing 3 inboards of workpiece S1, supply with sticker R.For example, the nozzle of the divider (dispenser) that possesses from the sticker feedway drips as the ultraviolet hardening resin of sticker R.
Then, with respect to workpiece S1 and applying workpiece S2.For example, in laminating apparatus, on the workpiece S1 on the worktable (table), mounting workpiece S2, and make pressing roller (roller) while on workpiece S2, press and move.Whereby, push workpiece S2 with respect to workpiece S1.
At this moment, as shown in Figure 4, because of workpiece S2 to the pressing of sealing 3, sealing section 3 avalanches, and sticker R also pressed, so sticker R is in sealing 3 interior continuous expansions.Then, when sticker R arrives the interior week of sealing 3, further along interior Zhou Liudong, and arrive enlarged portion 31.
As shown in Figure 5, the sticker R that flows to enlarged portion 31 stops in entrance or the inside of enlarged portion 31.In this case, bubble A assembles along the inner edge of sealing 3, gos deep into the inside of enlarged portion 31.Like this, sealing 3 is interior is filled by sticker R, and bubble A is extruded to enlarged portion 31, so can residual bubble A in the field range W.In addition, even if identical workpiece S1, whether in a plurality of enlarged portion 31, sticker R enters which enlarged portion 31, in forms such as entrance stop, and is sometimes identical, sometimes different.
So, in the sealing 3 between workpiece S1 and workpiece S2, just form the sticker filling part 4 of having filled sticker R.Then, sealing 3 and sticker filling part 4 are carried out cure process.For example, in evacuated vacuum chamber, utilize the ultraviolet lamp irradiation ultraviolet radiation.Whereby, finish the bonding structure body M that comprises sealing 3 and the adhesive coating B of sticker filling part 4 through hardening fully.In addition, in the bonding structure body M that finishes, the form of the sticker R of each enlarged portion 31 both can be identical, also can comprise aforesaid different shape.And, irradiation ultraviolet radiation in a vacuum when hardening fully, also can be in atmosphere irradiation ultraviolet radiation.After the applying because the part of sticker contact atmosphere is less, even if therefore in atmosphere irradiation ultraviolet radiation also can harden.
[effect]
According to present embodiment as implied above, can prevent that sticker R from overflowing outside workpiece S1, and bubble A can be expelled to outside the field range W.Therefore, it is interior without the residual bonding structure body M of bubble to make field range W, and yields is improved.
And, by forming enlarged portion 31, the discharge position of guaranteeing in advance sticker R and bubble A.Therefore, even if cause that because sticker R is deteriorated viscosity changes, the molten process conditions such as gas flow variation of depositing change, also can absorb amount of flow change, bubble A that these variations cause and increase etc.
In addition, sealing 3 is to utilize printing and uniformly formation, so can effectively make.For example, the time that is used to form sealing 3 significantly shortens, because of this time shorten, so that the execution of other steps can not be restricted in.
[other embodiments]
The present invention is not limited to aforesaid embodiment.For example, form as follows also is contained in the present invention.
(1) position of enlarged portion, shape, quantity etc. are not limited to the illustration of described embodiment.For example, as shown in Figure 6, can form a plurality of rectangle enlarged portion 31 at sealing 3.As shown in Figure 7, can form at sealing 3 a plurality of enlarged portion 31 of triangular waveform.As shown in Figure 8, a plurality of enlarged portion 31 that can the forming curves waveform.
If a plurality of enlarged portion 31 are set in this way, then be difficult to assemble a plurality of bubble A, the size that enters the bubble A of each enlarged portion 31 diminishes.Therefore, bubble A incorporates sticker easily, thereby the evanescence that becomes.Therefore, the production time can be shortened.By guaranteeing standing time, also can promote the disappearance of bubble A after fitting.
In the situation that a plurality of enlarged portion 31 are set, also can adopt the position that makes the easy shape of assembling of bubble and be arranged on the easy gathering of bubble.For example, as shown in Figure 9, can be in four corners of sealing 3 and the centre on limit, the enlarged portion 31 of forming curves shape.Whereby, can reduce the residual of bubble.
And shown in Figure 10 (a), Figure 10 (b), the zone in the enlarged portion 31 also can form field range W side and become the narrower narrow width part 31a of width, becomes the wider wide width part 31b of width with field range W opposition side.That is to say that the end of narrow width part 31a is communicated in the zone corresponding to field range W, the other end of narrow width part 31a is communicated in wide width part 31b.At this moment, can pass through narrow width part 31a, suppress the situation that sticker R flows into each enlarged portion 31 in a large number, and bubble A is expelled to enlarged portion 31.Whereby, can save the quantity delivered of sticker R.And, also tail off to the inequality of the influx of each enlarged portion 31, therefore can also reduce the inequality of coating thickness.In addition, in the excessive situation of the amount of sticker R, sticker R can flow into wide width part 31b from narrow width part 31a, thereby prevents from spilling.
(2) the formation method of sealing is not limited to serigraphy.For example, can also pass through the methods such as impact transfer printing, laser transfer, form sealing.When utilizing transfer printing to form sealing, also can all and uniformly form sealing for workpiece.
And, can also utilize divider, ink gun (the ink jet head) coating resin of supplying with resin material, form sealing.Whereby, can suitably select the formation pattern of various sealings to be used.From viewpoints such as optical characteristics or material contaminations (contamination), resin it is desirable to use identical from sticker filling part kind but the different persons of viscosity, but is not limited thereto.
By repeatedly forming (printing, transfer printing, coating etc.) sealing, can also guarantee height.At this moment, when forming sealing, by carry out cure process at every turn or every stipulated number, can suppress levelling (leveling) at every turn.
(3) the formation method of enlarged portion also can variety of methods.For example, as shown in figure 11, when forming sealing 3, the resin discharge rate of partial adjustment divider produces the wide and narrow of width.Whereby, can be made as enlarged portion 31 in the position that the width of sealing 3 is narrower.
And, as shown in figure 12, by coating resin, form after the narrower sealing 3 of width wide cut on the narrower sealing 3 of this width and coating resin by phased manner can be made as enlarged portion 31 in the position that width is narrower whereby.As shown in figure 13, only outstanding to the inside by making the wide cut part, can also save required space (space), the outside.In addition, also can pass through printing, transfer printing, and form the sealing 3 of the shape of Figure 11～Figure 13.In the situation of printing, transfer printing, both can form uniformly, also can by dually print overlappingly, transfer printing forms.
In addition, can also be after forming sealing, a part of removing sealing, and form enlarged portion.For example, as shown in figure 14, by the part of sealing 3 inner edges is removed, can form enlarged portion 31.As one of method of removing, such as Figure 15, shown in Figure 16, the nozzle N that consideration will be connected in vacuum source is inserted into the inner edge of sealing 3, the suction remove portion.This nozzle N is forming notch part h at the leading section of insert-seal section 3, therefore aspirates the space-time air-capacitor and easily flows into from notch part h, thereby aspirate easily.In addition, even if forming by a part of removing sealing 3 in the situation of enlarged portion 31, shown in Figure 17 (a), Figure 17 (b), also can form enlarged portion 31 in the mode that comprises narrow width part 31a and wide width part 31b.
In addition, as removing utensil, removing device and also consider other forms.Also can pass through the combination of glass pipette (spuit), scraper, contact pin, pocket knife, pin etc. or these article, and a part of removing sealing.The member of removing the contact workpiece S1 such as utensil it is desirable to can be to the material of workpiece S1 injury.For example, consider resin utensil or applied the utensil of resin.As an example of resin, for example consider teflon (polytetrafluoroethylene, PTFE) etc.
(4) sticker also is not limited to ad hoc approach to the supply method in the sealing.For example, as shown in figure 18, also can utilize the divider of multitube (multiple string), sticker R is coated with into a plurality of wire.At this moment, width, the interval of coating line that can also be by adjusting sticker R make the position, corresponding with enlarged portion 31 of easy generation bubble.For example, consider the position that the bubble between the coating line of sticker R produces easily, be coated with sticker R in enlarged portion 31 corresponding modes.Whereby, the displacement that bubble enters to enlarged portion 31 shortens, thereby can shorten the production time (tact time).And, diminish owing to be gathered in the bubble of each enlarged portion 31, so evanescence.
In addition, can variety of methods, as utilize the method for cylinder coating sticker, the method for utilizing squeegee (squeegee) coating, spin coating method etc.In addition, sticker can be used the sticker identical or different with sealing.
(5) kind of sealing, the employed sticker of sticker filling part is not limited to ultraviolet hardening resin.Can use the resin of all kinds, as utilize other electromagnetic waves and resin of hardening, thermoset resin (thermoset resin) etc.At this moment, according to the resin kind, the method for cure process considers to use the whole bag of tricks such as irradiation electromagnetic wave, changing temperature (heating, cooling), air-supply.Processing when therefore, sealing temporarily being hardened is also according to resin and difference.In addition, the temporary transient sclerosis of sealing is not to carry out.
(6) shape of the line of sealing formation and unrestricted.Can be that square, circular, oval, other polygons, curve are circular.For example, as shown in figure 19, exist at workpiece S1 in the situation of the regional Z that should not be coated with sticker, the mode that also can avoid this zone Z forms sealing 3.
And the position that forms sealing is not limited to the line of periphery of the supply area of regulation sticker.For example, also can be the line of stipulating the contour of supply area at the edge of circle or round disk (disk).Interior contour when also comprising the inboard and having empty band.
