Description

The manufacturing installation of adhesive coating device, display device component and manufacture method

Technical field

The present invention relates to a kind of adhesive coating device, the manufacturing installation of display device component and the manufacture method of display device component that following technology is improved, this technology be the pair of workpieces that such as forms display unit to fit and on workpiece the technology of coating adhesive.

Background technology

Generally speaking; with liquid crystal display or organic electroluminescent (Electroluminescence; EL) display is the flat display unit (flat-panel monitor (flat panel display)) of representative, is the groups such as the protection panel (skin plate (cover panel)) on the touch panel (touch panel) of display floater, operation optionally and protection surface, backlight and light guide plate thereof entered in the framework of flat-panel monitor and form.

(hereinafter referred to as the workpiece) laminations such as these display floaters, touch panel, protection panel, backlight and light guide plate thereof group enter in the framework of flat-panel monitor.Each workpiece individually or with the state group of lamination in advance enters.Such as, also use is configured to the component that lamination on protective cover has the composite panel of touch panel sometimes.

In addition, display floater also use group sometimes enter to have the display floater of the function of touch panel.So, there is various form as workpiece, but below, have the workpiece lamination of more than 2 to be called display device component the workpiece lamination forming display unit.

When being provided with gap between each workpiece at lamination being this display device component, the visibility of the display surface of display can be caused to reduce because of reflected ambient light.In order to tackle this, by by each workpiece via adhesive layer laminating and lamination comes between each workpiece of landfill gap.

Have in the lamination of this workpiece and use adhesive sheet to carry out the method for fitting and use the aqueous binder with mobility to carry out the method for fitting.Adhesive sheet price comparison compared with adhesive is high, and needs the steps such as the stripping of peeling paper.Therefore, from considerations such as the requirements of cost cutting in recent years, use the laminating of adhesive to become main flow.

In addition, sometimes this adhesive layer is required as each workpiece between fender to protect the function of workpiece.And then, in addition, make the area of workpiece also become large because of display maximization etc., thus workpiece is easy to produce distortion.Therefore, protecting workpiece to absorb distortion, having the tendency that the thickness of adhesive layer requirement is increased.Such as require that adhesive layer is hundreds of micron (μm) thickness.

If use aqueous binder to guarantee the thickness of this adhesive layer, then required amount of binder increases.Thus, be coated on the adhesive flow on workpiece and be easy to expose from workpiece.Thus, workpiece surperficial coating adhesive and harden (with reference to patent document 1) in the mode being coated with shape not avalanche temporarily.

Namely, one side from slit (slit) type nozzle by ultraviolet (ultraviolet, UV) adhesive of hardening resin is coated on the coated face of workpiece, and one side makes nozzle and workpiece relative movement, coating adhesive on the whole coated face of workpiece thus.Now, utilize irradiation portion to irradiate UV light near the nozzle after following near nozzle, make adhesive harden thus temporarily and suppress flowing.

After being just coated with described adhesive, there is the situation of the surface configuration instability of adhesive.If as so the binding face of adhesive shape unsure state under to fit workpiece, then having the edge of the adhesive of laminating to enter to depending on recognizing region etc. is not the possibility of desired state.In addition, after coating, produce because of the avalanche caused by bending at adhesive surface along with the process of time.If fitted with the state that there is this avalanche at binding face, then cannot knoobbling or depression and produce hole completely.

In addition, general protection panel has window portion and frame portion.Window portion is the visual region recognizing the viewing area of display floater.Frame portion is the low part of the transmitance of the visible ray that the mode of the size and shape dividing exit window portion is formed.In recent years, even if to be of a size of the requirement that also will reduce on an equal basis the size of display floater self high in the viewing area of display floater.In this situation, as Suo Shi Figure 19 (A), the window portion region C1 being fitted in the protection panel H on display floater I via adhesive R becomes large, and frame portion region C2 becomes very narrow.Thus, require that the position of adhesive R end and shape have high accuracy to become the mode of the state of the degree shown in Figure 19 (A).

Such as, when observing the end of adhesive R from window portion region C1 as shown in such as Figure 19 (B), viewing area can be hindered.The end of adhesive R becomes the R shape with radian to a certain degree, therefore must to overlook down the mode coating adhesive R inside window portion region C1 not observing this R-portion.If there is R-portion inside window portion region C1, then the position corresponding to the dotted portion shown in the hollow arrow in figure looks like doublet sometimes under overlooking.Therefore, this R-portion must be made minimum.Certainly, the state that only R-portion is present in inside window portion region C1 also becomes problem.

In addition; even if make the end of adhesive R not be overlapped in viewing area; as as Suo Shi Figure 19 (C), when adhesive R is exposed in the edge of display floater I or protection panel H, also likely harmful effect is brought to other components, mostly therefore be the situation of not allowing.

And then adhesive R just starts flowing after just coating, and therefore end shape passes through along with the time and changes.Such as, adhesive R after coating, along with the time through and produce avalanche caused by bending on its surface with the binding face of protection panel H.If fitted under the state that there is this avalanche, then as Suo Shi Figure 19 (D), cannot knoobbling or depression and produce hole G completely.

Detailed description of the invention

With reference to graphic, embodiments of the present invention (hereinafter referred to as embodiment) are specifically described.

[formation]

First, referring to figs. 1 through Fig. 9, the formation of present embodiment is described.

[workpiece]

In present embodiment; the workpiece S1, the workpiece S2 that become laminating object are the component forming display device component, form the laminate of display device component by panel (skin plate (cover panel)) will be protected to fit on a display panel via adhesive R.This device is the manufacturing installation of the display device component of the laminate manufacturing this display device component.

[manufacturing installation of display device component]

As shown in Figure 1, the manufacturing installation 100 of display device component has adhesive coating device 1, laminating apparatus 2, curing system 3 and carrying device 4.In addition, the manufacturing installation 100 of display device component possesses control device 7.Control device 7 carries out the conveyance SECO etc. of the action control of the device forming each portion and workpiece S1, workpiece S2.

Carrying device 4 comprises the driving mechanism of conveying unit and this conveying unit workpiece S1, workpiece S2 transported to each portion.As conveying unit, such as, consider rotating disk (turntable), conveyer (conveyor) etc., as long as but be the device that can transport workpiece S1, workpiece S2 between described each device, then also can be any device.

Workpiece S1, workpiece S2 move into the manufacturing installation 100 to display device component by loader (loader) 5, and utilize carrying device 4 to transport.Adhesive coating device 1, laminating apparatus 2 and curing system 3 is configured with along carrying device 4.Workpiece S1, workpiece S2 are picked from carrying device 4 by not shown pickup device, and move into mouth via not shown and carry out moving into and taking out of to each device.The step of the following detailed description in each device and manufacture display device component L, and take out of display device component L by emptier (unloader) 6 from the manufacturing installation 100 of display device component.

[adhesive coating device]

Adhesive coating device 1 as shown in Figure 2 as there is support portion 12, coating part 10 and irradiation portion 11.

[support portion]

Workpiece S1 in the adhesive coating device 1 of 12 pairs, support portion supports to make the supine mode of coating.This support portion 12 has microscope carrier (stage) 12a and driving mechanism 12b.Microscope carrier 12a is the flat platform of mounting workpiece S1.Driving mechanism 12b is the mechanism that microscope carrier 12a is reciprocated in the horizontal direction.As driving mechanism 12b, such as, consider the ball screw rotated by drive source.But, as long as the device for placed workpiece S1 can be made to reciprocate in the horizontal direction, then also can be any device.Driving mechanism 12b is made microscope carrier 12a start, stops speed that is mobile and movement to be controlled by control device 7.

[coating part]

Coating part 10 is such as having the slit coater of slit, and the adhesive R be accommodated in storage tank T is supplied to workpiece S1 via circulation path and pipe arrangement and the valve regulating quantity delivered by it by pumping out.

Slit is opening that is parallel with the coated face of workpiece S1 and that slenderly extend on the direction that the relative movement direction with workpiece S1 is orthogonal, and the length of its long side direction and the width of workpiece S1 are equal or be slightly shorter than the width of workpiece S1.As shown in Figure 3, the fore-end of coating part 10 forms nozzle (gap nozzle), this nozzle with the position of workpiece S1 subtend on possess described slit.

And then, coating part 10 is provided with shielding portion 10a.Shielding portion 10a is that the energy covered from irradiation portion 11 prevents this energy exposure to the component of the adhesive R of spray nozzle front end.This shielding portion 10a such as can be set to the tabular component of the side, irradiation portion 11 being arranged on coating part 10.In addition, according to coating part 10 and the distance in irradiation portion 11, the exposure intensity, direction of illumination, range of exposures etc. in irradiation portion 11 different, also there is the situation that the impact of irradiation energy on the adhesive R of spray nozzle front end is little, in this situation, also shielding portion 10a can not be set.

In addition, coating part 10 is such as arranged in the mode be elevated on the direction orthogonal with the coated face of workpiece S1 by not shown driving mechanism.Adhesive R controls to regulate by the Valve controlling of control device 7 and pump from the spray volume of nozzle.In addition, the shape of the adhesive R after just ejection depends on relative moving speed and space (clearance) of the spouting velocity of adhesive R, viscosity and temperature, coated face and coating part 10.In addition, the shape of the adhesive R after coating changes as following.

In addition, as long as adhesive R is the resin by hardening from external irradiation energy.Such as can consider ultraviolet (UV) hardening resin or thermosetting resin.In present embodiment, ultraviolet (UV) hardening resin is used to be described.The viscosity of the adhesive R used also is not particularly limited.But as the viscosity that the necessity utilizing interim sclerosis to suppress to flow is high, setting 2,000 cps ~ tens thousand of cps, is preferably 2,000 cps ~ 5,000 cps that ratio of viscosities is lower.

[irradiation portion]

Irradiation portion 11 is handling part adhesive R being irradiated to the energy being used for interim sclerosis.This irradiation portion 11 as shown in Figure 4 as there is the irradiation source 11a of multiple irradiation energy.In this irradiation portion 11, such as on parallel with the coated face of workpiece S1 and orthogonal with the relative movement direction of the workpiece S1 shown in the hollow arrow in figure direction, be equally spaced configured with multiple light emitting diode (light emitting diode with workpiece S1 subtend, or the irradiation source 11a such as laser diode (laserdiode, LD) LED).Such as, when adhesive R is UV hardening resin, irradiation source 11a is set to the irradiation source exporting UV (ultraviolet) light, the UV illumination from irradiation source 11a is incident upon the adhesive R be coated on workpiece S1.In addition, when adhesive R is thermosetting resin, the heat energy of self-heat power irradiates in irradiation portion 11.Irradiation portion 11 in this situation such as can be set to the irradiation portion exporting Ir (infrared ray).In addition, in Fig. 4, become 2 row, but also can be 1 row, also can be more than 3 row, be not particularly limited.In addition, irradiation source 11a also can touch or link each other, and this configuration also can with the configuration of sawtooth (staggered (zigzag)) state.

The mode that the irradiation in irradiation portion 11 becomes interim hardening state with adhesive R is carried out.Interim sclerosis refers to the state not reaching and harden completely.Such as, adhesive R is made to form interim hardening state by irradiating the energy of the required little energy that hardens more completely.This is by irradiating with weak intensity or making with short irradiation adhesive R be interim hardening state.In addition, in certain UV hardening resin, when irradiating UV in an atmosphere, the interim hardening state of the type that the sclerosis becoming the surface of adhesive R because oxygen suppresses (oxygen inhibition) etc. is no longer in progress.

The unlatching (ON) of the energy exposure in irradiation portion 11, close (OFF), the intensity of irradiation energy controlled by control device 7.In addition, irradiation portion 11 is configured to the variable spaced with coating part 10.Such as, as shown in Figure 2, be placed through position changing unit and shift mechanism 11x makes irradiation portion 11 dynamic relative to the variable spaced in the horizontal direction of coating part 10.This shift mechanism 11x is set to the changeable state, the state with the movement independently of irradiation portion on the relative movement direction of workpiece S1 11 and coating part 10 that interval in the horizontal direction of irradiation portion 11 and coating part 10 are fixed as desired distance.As shift mechanism 11x, such as, consider the ball screw rotated by drive source.Shift mechanism 11x is made irradiation portion 11 start, stops speed that is mobile and movement to be controlled by control device 7.

In addition, as long as shift mechanism 11x is the device that irradiation portion 11 can be made to reciprocate in the horizontal direction, then also can be any device.Function with coating part 10 movement independently such as also can not be set in shift mechanism 11x, and the mode being only in desired position with irradiation portion 11 and coating part 10 fixes the interval of irradiation portion 11 and coating part 10.That is, if preset the acceleration and deceleration of relative movement, constant speed, then the interval of irradiation portion 11 and coating part 10 can also be determined in the mode can carrying out irradiating in desired irradiation sequential.Therefore, with the configuration irradiation portion 11, interval determined as so.Therefore, such as, as shift mechanism 11x, also can be set to and coating part 10 can be made to slide in as the elongated hole of installing hole mobile and screw etc. can be utilized to be fixed on the formation of desired position.Also can be set to any one by being arranged in multiple installing hole and the shift mechanism 11x of the position of coating part 10 can be changed.Also can be set to and can be arranged on slide block slidably and movingly and stop part by multiple position determines the shift mechanism 11x of fixed position.When being set to this formation, can according to variations in temperature the position of inching coating part 10.

And then in present embodiment, the irradiation sequential of the 11 pairs of adhesive R irradiation energies in irradiation portion is controlled by control device 7.This irradiation sequential is the nowed forming of the following adhesive R based on inventor's probe gained, and be set in adhesive R surface and the binding face of workpiece S2 becomes smooth the 1st sequential and binding face produces between the 2nd sequential of avalanche.

(nowed forming of adhesive)

Inventor distinguishes the following phenomenon of generation after carrying out probe to the flowing of adhesive R.When adhesive R is plane being coated on workpiece S1, the shape of the adhesive R end of this coating changed along with the time.That is, be coated with as rectangular-shaped at adhesive R, its end i.e. 4 limit shapes change from during coating.Now, mainly be contacted with workpiece S1 coated portion subtend adhesive R face side, namely become the change in shape of the upper surface side of binding face.This change is from after just coating and restrain in the set time.Time before this convergence can change according to the state of adhesive R (shape etc. after viscosity, thickness, just coating).

More specifically, when the nozzle and workpiece S1 that make the coating part 10 of ejection adhesive R relatively move and workpiece S1 surface coating adhesive R, after firm coating, namely adhesive R be just contacted with the surface, top of the coating of the adhesive R behind workpiece S1 surface, as Suo Shi Fig. 5 (a) with the contact portion of workpiece S1 and adhesive R for anchoring section (anchor) and produce and also delayed the large curved surface r1 of semi-steep radius of curvature by the direction tractive to coating part 10 movement.Meanwhile, namely surface tension plays a role towards the direction of top outer rim in direction, top to adhesive R.Along with coating part 10 away from and tensile force dies down, the substitute is surface tension strongly to play a role, as as Suo Shi Fig. 5 (b), the bight radius of curvature of the edge, cross section on surface become minimum close to approximate right angle before adhesive R flow, in adhesive R surface, produce the tabular surface r2 almost parallel with workpiece S1 surface with the binding face of another workpiece S2.The time point producing this tabular surface r2 is the 1st sequential.

Thereafter, along with time process, as Suo Shi Fig. 5 (c), surface tension makes the adhesive R of corners of cross section and then produces the height protuberance r3 different with tabular surface r2 to the medial movement contrary from the direction towards outer rim.Now, the situation producing depression in a part is also had.The state of at least one of protuberance, depression is had to be called avalanche by producing in adhesive R as so.The time point producing this avalanche is the 2nd sequential.After the 2nd sequential, avalanche also restrains after survival for the time being.

On the other hand, in the terminal of coating, along with coating part 10 rises after stopping ejection adhesive R, as as Suo Shi Fig. 6 (a), adhesive R is elongated, thereafter as Suo Shi Fig. 6 (b), the adhesive R of workpiece S1 side and coating part 10 side disconnects, and therefore produces outstanding r4 in the bight, edge of this adhesive R.This outstanding r4 as Suo Shi Fig. 6 (c) along with the time pass through, absorbed by gravity or surface tension etc. by the adhesive R of workpiece S1 side and disappear, in adhesive R surface, therefore producing the tabular surface r5 almost parallel with workpiece S1 surface with the binding face of another workpiece S2.The time point producing this tabular surface r5 is also the 1st sequential.Thereafter, along with time process, produce the height avalanche different with tabular surface r5 in the same manner from Fig. 5 (c).The time point producing this avalanche is also the 2nd sequential.

In addition, even if at the top from coating to edge, the i.e. side parallel with coating direction of the midway of terminal, also produce the change identical with Fig. 5 (a) ~ Fig. 5 (c).But as following, according to being moved caused extended state or the position relationship with coating direction by coating part 10, and change in the sequential different from top.

According to the above, the 1st sequential at top and the interval of the 2nd sequential, the 1st sequential of terminal and the 1st sequential of the interval of the 2nd sequential and side and the interval of the 2nd sequential may not be consistent.In addition, at top or the side of coating, also have and start to be coated with the situation roughly side by side producing tabular surface.In this situation, at top or side, the 1st sequential becomes and starts sequential roughly simultaneously with coating.

If hardened early than the 1st sequential temporarily, then shape is fixed on the large curved surface r1 state of radius of curvature, is therefore easy to produce the doublet shown in Figure 19 (B) or the line caused by the bight, edge observing adhesive R.If interim sclerosis is later than the 2nd sequential, then shape is fixed on the state producing avalanche, is easy to produce hole B as therefore as Suo Shi Figure 19 (D).

1st sequential, the 2nd sequential become front end and the rear end of the time of allowing as the sequential starting each portion of adhesive R to irradiate.As long as to the minimum time that the irradiation time in each portion of the adhesive R shape that is adhesive R is fixed.This depends on the state of the interim sclerosis produced by irradiating.Such as, comparatively ideal is that at least interim hardening ratio becomes 20%.This flows because of laminate pressure when fitting at the following adhesive R that is related to, thus exposes as Suo Shi Figure 19 (C).

Above situation especially has influence on the 2nd sequential becoming the rear end irradiating sequential.That is, the 2nd sequential is produce the critical point before avalanche, if therefore irradiated in the 2nd sequential, then likely cannot maintain described interim hardening ratio.In this situation, set irradiation sequential in the 2nd sequential a little earlier.

(irradiating the setting form of sequential)

Irradiation sequential between 1st sequential of present embodiment and the 2nd sequential is from during the edge of adhesive R generation tabular surface r2, tabular surface r5 are to producing avalanche in this edge as such as Suo Shi Fig. 5 (b), Fig. 6 (c).To generation avalanche, refer to that avalanche maintains the state that can not cause in the permissible range of hole.

The setting of this irradiation sequential realizes by following form.

(1) irradiation portion is to the time of advent of irradiated site

First, irradiation portion 11 sets to the time of advent of the adhesive R completing coating in the mode become between described 1st sequential and the 2nd sequential.Namely, set the interval in coating part 10 and irradiation portion 11 as follows and make coating part 10 and irradiation portion 11 poor to the generation time time of advent at same position, namely irradiation portion 11 is to the location, adhesive R position for being undertaken irradiating by irradiation portion 11, time from being coated with the adhesive R-portion for carrying out this irradiation to described irradiation portion 11 locates, namely irradiation portion 11 became between the 1st sequential and the 2nd sequential to the time of advent of adhesive R.Poor by this time of advent, if arrival while irradiation energy, then can produce irradiation time difference.Said interval also comprises irradiation portion 11 and moves independently with coating part 10 and the form that changes herein.

Set by this interval and irradiation portion 11 starts when arriving the top of coating to irradiate, thus proceed irradiation thereafter, adhesive R can be made thus temporarily to harden with flat condition.In this situation, by setting the interval in irradiation portion 11 and coating part 10, also can need not irradiate continuously in the irradiation in irradiation portion 11 that nearby temporarily stops of the terminal of coating as following.

(2) setting of stipulated time

The time of setting from the coating of adhesive R till irradiation portion 11 is irradiated the top of coating and top irradiate sequential, irradiate sequential with the time at the end of the coating of adhesive R to irradiation portion 11 is irradiated the terminal be coated with and terminal.In addition, refer to when coating starts that the adhesive R such as sprayed from coating part 10 is attached to the time point of relative movement coating part 10 on workpiece.The time point that such as coating part 10 terminates the ejection of adhesive R and coating part 10 and starts to rise is referred at the end of coating.

(3) top be coated with and the timing settings of terminal

Such as, 1st sequential at the top of the coating of adhesive R is set to following sequential, namely in this sequential, returning to its curved Deformation Curvature by the movement of coating part 10 end face that the adhesive R of surf deform occurs in cross section by pullling is minimum state and planarized.On the other hand, 1st sequential of the terminal of the coating of adhesive R is set to following sequential, namely in this sequential, by the disconnection of the adhesive R of the workpiece S1 side caused by the movement by the coating part 10 and adhesive R of coating part 10 side, and the ledge that the adhesive R in workpiece S1 side is produced disappears.In addition, the 2nd sequential of the top of the coating of adhesive R and terminal is set to the sequential producing avalanche in edge.

(4) corresponding with the viscosity of adhesive timing settings

In addition, according to the difference of the viscosity of adhesive R, in Fig. 5 (a) ~ Fig. 5 (c) and Fig. 6 (a) ~ Fig. 6 (c), the pace of change of illustrative adhesive R is different.That is, the viscosity of adhesive R is higher, and flowing becomes slower, and therefore change is slow, and viscosity is lower, and flowing becomes faster, and therefore change is fast.Therefore, the viscosity of adhesive R is higher, make the 1st sequential and the 2nd sequential slower, the viscosity of adhesive R is lower, makes the 1st sequential and the 2nd sequential more early.

(test)

The viscosity of described adhesive R depends on kind or the temperature of adhesive R.And then the coating thickness of adhesive R also impacts the flowing of adhesive R.This coating thickness or initial coating shape also affect by the spray volume of adhesive or the translational speed of coating part 10.Therefore, described 1st sequential and the 2nd sequential can carry out testing according to the kind of the adhesive preset, temperature, coating thickness, coating operating state etc. and determine.

Such as, in order to determine that the test example of the 2nd sequential is described.First, use the base board for display device of 10 inch dimension as workpiece S1, and use gap nozzle as coating part 10.With gap nozzle 5 seconds roughly whole surperficial coating adhesive R to this substrate.When being coated with coating thickness 200 μm at normal temperatures by the adhesive of viscosity 2500cps, its edge started avalanche in 1 second ~ 2 seconds.2nd sequential is by observing this avalanche state and measuring the time and obtain.When such as after top, terminal, side are all set to coating 2 seconds of the time starting this avalanche, the 2nd sequential becomes 2 seconds that start at from coating.For the 1st sequential, also by observing the shape of adhesive R from coating starts at top, and terminal observe after coating terminates adhesive R disconnect after shape and measure the time and obtain.

In addition, also can obtain viscosity, coating thickness, temperature, coating operating state and the binding face planarized time according to described result of the test or start the relational expression of time of avalanche, and control based on this relational expression.

[effect]

Except with reference to except described Fig. 1 ~ Fig. 9, also with reference to the time diagram of Figure 10, the state transition diagram of Figure 11 (a) ~ Figure 11 (d) and Figure 12 (a) ~ Figure 12 (d) and being described the effect of the present embodiment with above formation.In addition, the position and size etc. in microscope carrier 12a, the workpiece S1 of Figure 11 (a) ~ Figure 11 (d) and Figure 12 (a) ~ Figure 12 (d), workpiece S2, coating part 10, irradiation portion 11 be only for illustration of the performance of expedient property.

(summary)

First, as shown in Figure 2, immediately below coating part 10 with irradiation portion 11, the microscope carrier 12a being placed with workpiece S1 by driving mechanism 12b in the horizontal direction (in figure shown in arrow from right to left) mobile.Coating part 10 and the relative movement of irradiation portion 11 relative to microscope carrier 12a are equivalent with the relative movement relative to workpiece S1.

The coating of adhesive R from the end, one side (being left end in figure) of workpiece S1, and terminates in the end (being right-hand member in figure) of subtend therewith.The side, top this coating started is set to coating upstream side, and the end side that coating terminates is set to coating downstream.And, as shown in Figure 3, being configured in the irradiation portion 11 of the coating upstream side of coating part 10, making adhesive R be interim hardening state (being hachure part in figure) by irradiating the coated portion immediately below it in order to the energy such as UV light hardened temporarily.

(time diagram)

Next, the action sequence of time diagram to each portion of adhesive coating device 1 with reference to Figure 10 is described.The transverse axis of Figure 10 is the time.The translational speed that (a) on the longitudinal axis of Figure 10 is microscope carrier 12a, b () is the spray volume of the adhesive R from coating part 10, c () is the height of coating part 10, (d) is for irradiation portion 11 is to ON, OFF of the irradiation of adhesive R and exposure intensity.In addition, represent the 1st sequential of side, described top with T1, represent the 2nd sequential of side, described top with T2, represent the 1st sequential of end side with T1', and represent the 2nd sequential of end side with T2'.Below, (a) ~ (d) is described in detail.

The translational speed of (a) microscope carrier

Time point TA represent start coating.Represent that the movement of microscope carrier 12a becomes the time of constant speed from time point TB to time point TC.This constant speed is coated on the fixed speed on workpiece S1 with uniform thickness for adhesive R when the spray volume of the adhesive R of the time per unit of coating part 10 is fixed amount.In addition, this constant speed is coating part 10 and the relative moving speed of microscope carrier 12a, different according to the viscosity, spray volume, desired coating thickness etc. of adhesive R.

The speed of microscope carrier 12a is accelerated from time point TA, and reaches constant speed at time point TB.Microscope carrier 12a maintains the state of constant speed, and reduces speed now from the time point TC nearby of the time point TD of coating end, and temporarily stops at time point TD.This be as following in order to the adhesive R completing coating is disconnected from the adhesive R of nozzle side by the rising of coating part 10.Suppressing the variation before the 1st sequential to stably carry out the disconnection of adhesive R, preferably stopping.But, there is situation about easily disconnecting according to the viscosity of adhesive R etc., in this situation, also can not stop and maintaining constant speed or disconnecting under the state of movement of slowing down.Thereafter, microscope carrier 12a with make coating part 10 from microscope carrier 12a keep out of the way and mode that irradiation portion 11 comes the terminal of the coating of adhesive R from time point TE again mobile, slow down after the short time accelerates and also stop at time point TF.

B () is from the spray volume of the adhesive of coating part

The nozzle ejection adhesive R from coating part 10 is started at time point TA.Coating part 10 corresponding to the acceleration of microscope carrier 12a, and becomes fixing mode with the coating weight of the per unit area of workpiece S1 and increases spray volume from time point TA.From time point TB to time point TC, because microscope carrier 12a maintains constant speed, therefore the spray volume of coating part 10 is also fixing.Thus, the coating weight of the per unit area of workpiece S1 becomes fixing.Coating part 10 becomes fixing mode corresponding to the deceleration of microscope carrier 12a with the coating weight of the per unit area of workpiece S1 and reduces spray volume from time point TC.Then, ejection is stopped at time point TD.When spraying stopping, when making pump and supply, contrary earthquake is done, and can prevent adhesive R drip thus.

Described spray volume all determines in the mode becoming desired fixing coating thickness from time point TA to time point TD.That is, even if microscope carrier 12a acceleration and deceleration, also spray volume is changed in the mode becoming the coating thickness identical with the interval of constant speed.

In addition, (b) in Figure 10 represents the change from the spray volume of the adhesive R of coating part 10, and the Control timing sequence of the pump that may not stop with the supply and supplying for adhesive R and valve etc. is consistent.That is, owing to producing time lag (time lag) in the Control timing sequence of pump and valve etc. and the change of resultant spray volume and sequential thereof, therefore consider this time lag and become the mode control pump and valve etc. of (b) with spray volume.In addition, the mobile beginning of microscope carrier 12a is set to time point TA with the ejection of adhesive R, and the adhesive R of ejection spread all between the spray nozzle front end and workpiece S1 of coating part 10 with the extremely short time.Therefore, there is slight deviation in the mobile sequential that starts to microscope carrier 12a from ejection.

The height of (c) coating part

Coating part 10 is in the height (standby height) of the position of readiness left from workpiece S1 in an initial condition.In order to start coating adhesive R, coating part 10 must to workpiece S1 close to and drop to can from nozzle to the height (coating height) of the position coating desired by workpiece S1.

That is, before time point TA, the decline till coating part 10 starts from standby height to coating height.And the time point TA that coating part 10 arrives coating height starts to spray adhesive R.In addition, Tu10Zhong, the sequential arriving coating height is identical with time point TA, as long as but before time point TA then no problem.

When stopping at time point TD microscope carrier 12a, coating part 10 is positioned at the terminal location of the workpiece S1 becoming coating terminal.As described in adhesive R spray volume control described in as, ejection also with stopping side by side terminating.Then, coating part 10 rises to standby height.Thus, the adhesive R of workpiece S1 side and the adhesive R of nozzle side disconnects.Standby height be set to make adhesive R so as disconnect needed for sufficient height.In addition, the sequential of each action of described explanation is an example.The knee-action of coating part 10 may not be consistent with the sequential of microscope carrier 12a movement with the sequential of spray action.

The irradiation in (d) irradiation portion

After the translational speed at time point TB microscope carrier 12a becomes constant speed, start the top irradiation energy utilizing irradiation portion 11 to the adhesive R be coated on workpiece S1.This irradiation starts sequential and irradiates sequential according to the top preset.As long as it is between the 1st sequential T1 and the 2nd sequential T2 that this top irradiates sequential, non-essential be time point TB after, from the consideration of the amount of the irradiation energy of per unit area uniform viewpoint, after preferred time point TB.

Irradiate sequential at this top, as Suo Shi Fig. 5 (b), the binding face of adhesive R becomes tabular surface r2, hardens in this condition temporarily.Irradiation portion 11 by the movement of microscope carrier 12a identically with coating part with workpiece S1 relative movement.Therefore, irradiation portion 11 one side along with the movement of workpiece S1 relative to coating adhesive R relative movement irradiation energy.Then, irradiation portion 11 temporarily stops irradiating at the time point TD that the movement of microscope carrier 12a and the coating of coating part 10 terminate.

The mode of coming the coating terminal of adhesive R at microscope carrier 12a with irradiation portion 11 starts the time point TE of movement again, and irradiation portion 11 starts to irradiate.When microscope carrier 12a the short time accelerate after slow down and when stopping at time point TF, irradiation portion 11 stop irradiation.

So, irradiation portion 11 temporarily stops the reason of irradiating to be as follows.When coating part 10 carries out in the terminal be coated with the action disconnecting adhesive R, irradiation portion 11 stops at above its adhesive R nearby.If continue in this condition to irradiate, then the quantitative change of the irradiation energy of the per unit area of the adhesive R immediately below irradiation portion 11 obtains superfluous, thus likely becomes the interim hardening ratio (more than 80%) being not suitable for fitting.Thus, temporarily irradiation is stopped to prevent superfluous irradiation with the stopping side by side irradiation portion 11 of microscope carrier 12a.So, carry out state for what control interim sclerosis effectively, preferably temporarily stop irradiating.But, according to exposure intensity or dwell time, also there is the situation that the amount of irradiation energy is not superfluous, in this situation, also can stop irradiating, also can weaken exposure intensity and deal with.And then, also make irradiation portion 11 continue mobile to coating direction by shift mechanism 11x and avoid a position cover.

So, the sequential again starting to irradiate after irradiating temporarily stopping is the sequential of the energy terminal of the coating of adhesive R being irradiated to interim sclerosis, according to the terminal irradiation sequential preset.As long as it is between the 1st sequential T1' and the 2nd sequential T2' that this terminal irradiates sequential.Irradiate sequential in this terminal, as Suo Shi Fig. 6 (c), become tabular surface r5 with the binding face of other workpiece, harden in this condition temporarily.

In addition, as described, when not making the irradiation in irradiation portion 11 temporarily stop, making irradiation portion 11 relative to the microscope carrier 12a stopped and coating part 10 relative movement by shift mechanism 11x.That is, irradiation portion 11 does not stop irradiating and starts mobile thus close to coating part 10.During this period, can to continue to irradiate close to the speed of constant speed near terminal by continuing to irradiate.Thereafter, if after the 1st sequential T1' irradiation portion 11 incoming terminal, then irradiation portion 11 also can not stop before incoming terminal and continue irradiate.In addition, irradiation portion 11 also can nearby stop in terminal and temporarily stop irradiating before the 1st sequential T1' arrives, and again moved after the 1st sequential T1' arrives and start to irradiate.In the process of irradiation portion 11 movement as so, comparatively ideal is maintain constant speed, but acceleration during mobile beginning and the deceleration before stopping are required.In addition, also can slow down in the mode of incoming terminal after the 1st sequential T1'.

(application step)

Secondly, be described with reference to Figure 11 (a) ~ application step of Figure 11 (d), Figure 12 (a) ~ Figure 12 (d) to the present embodiment according to described time diagram.In addition, (1) that below illustrates ~ (8) correspond respectively to Figure 11 (a) ~ Figure 11 (d) and Figure 12 (a) ~ Figure 12 (d).

(1) move to coating starting position by microscope carrier 12a, the ejiction opening being in the coating part 10 of standby height is positioned directly over the coating top of workpiece S1.And coating part 10 starts highly to decline to coating.

(2) when arriving coating height at coating part 10 and after stopping, when starting to spray adhesive R from coating part 10, adhesive R being supplied to workpiece S1.Spread all over to this workpiece S1 as adhesive R and be coated with after between height, microscope carrier 12a starts to move to coating direction, therefore starts to workpiece S1 surface coating adhesive R (Figure 10: time point TA).Microscope carrier 12a accelerates from this time point TA, and coating part 10 slowly increases the spray volume of adhesive R.

(3) at time point TB, microscope carrier 12a stops accelerating and becoming fixing constant speed, and the spray volume of the adhesive R of coating part 10 also stops increasing and becoming fixing.That is, in this condition, coating part 10 and irradiation portion 11 become constant speed relative to the relative moving speed of microscope carrier 12a, workpiece S1 and adhesive R.Irradiate instruction unit 72 from coating start i.e. microscope carrier 12a start mobile the counting of time started, and make irradiation portion 11 start to irradiate (Figure 10: time point TC) when becoming top and irradiating sequential.

In addition, the time from the movement of microscope carrier 12a to reaching constant speed can be known according to the setting etc. of the driving mechanism 12b of microscope carrier 12a.Therefore, as long as the mode of coming the top of coating with irradiation portion 11 after microscope carrier 12a becomes constant speed in advance based on this time sets the interval in coating part 10 and irradiation portion 11.Thus, the irradiation of irradiation portion 11 to adhesive R can be carried out from the top of coating with constant speed.

But the irradiation to the top of coating is as above irradiated sequential by top and is determined.Therefore, can irradiate for top the interval that the mode of irradiating top between the 1st sequential T1 of sequential and the 2nd sequential T2 sets coating part 10 and irradiation portion 11 to irradiate portion 11.Therefore, as long as the interval that can start to irradiate with constant speed is the interval irradiating sequential irradiation at top.Such as, or shift mechanism 11x can be utilized to set the interval in coating part 10 and irradiation portion 11 when designing.

When the inferior change top of the situation of the kind changing adhesive R irradiates sequential, as long as suitably change the interval of irradiation portion 11 and coating part 10.And then, also can not adjust the position in irradiation portion 11, but pass through the time that adjustment starts to irradiate and the top irradiation sequential adjusted for adhesive R.Therefore, the irradiation of irradiating sequential at top is realized by ON, OFF sequential of coating part 10 and the interval in irradiation portion 11, the irradiation in irradiation portion 11 or both combining.If set to irradiate the mode of coming top in sequential irradiation portion 11 at top, then irradiation portion 11 also can start to irradiate before arrival top.Such as, irradiation portion 11 also can start to irradiate by the time point shown in Figure 11 (b).In this situation, as long as only utilize the interval in coating part 10 and irradiation portion 11 to irradiate sequential to adjust top.

The amount homogenising of the irradiation energy of the adhesive R to per unit area can be made by irradiating with constant speed.But, also make the amount homogenising of irradiation energy by changing exposure intensity according to speed.In addition, according to degree or the viscosity of adhesive R, the degree of required interim sclerosis of speed, even if make exposure intensity fix and change speed, the amount uniformity of the irradiation energy of certain degree also can be maintained or be in permissible uneven scope.Therefore, also can start to irradiate with constant speed.

(4) microscope carrier 12a (Figure 10: time point TC) from the terminal that coating part 10 is about to the coating arriving workpiece S1 reduces speed now.Along with this deceleration, coating part 10 slowly reduces the spray volume of adhesive R.

(5) time directly over the terminal that coating part 10 arrives the coating of workpiece S1, microscope carrier 12a temporarily stops, and irradiates portion 11 also temporarily stopping irradiation and mobile (Figure 10: time point TD).Now, coating part 10 stops ejection adhesive R.

(6), under the state that microscope carrier 12a stops relative to coating part 10 as so, coating part 10 rises and stops at standby height.Because coating part 10 has stopped ejection adhesive R, the arbitrary time point during therefore before coating part 10 arrives standby height, the adhesive R of workpiece S1 side and the adhesive R of nozzle side disconnects.

(7) after the sequential that adhesive R disconnects effectively, microscope carrier 12a starts mobile (Figure 10: time point TE) again.The displacement of microscope carrier 12a is at least irradiate the distance that portion 11 can arrive the terminal of coating.The translational speed of microscope carrier 12a during this period changes deceleration into after the short time accelerates.Irradiate the counting that instruction unit 72 rises the time started from coating part 10, and make when becoming terminal and irradiating sequential irradiation portion 11 start to irradiate.As long as it is between the 1st sequential T1' and the 2nd sequential T2' that this terminal irradiates sequential, also non-essential is time point TE, but considers from the uniform viewpoint of the amount of irradiation energy, is preferably time point TE.In addition, the sequential that adhesive R disconnects effectively can confirm by testing thus set in advance.

(8) stop and the time point of the terminal of irradiation portion 11 arrival coating at microscope carrier 12a, irradiation portion 11 stops irradiating (Figure 10: time point TF).In addition, the non-essential a succession of coating action completed to workpiece S1 be positioned at the state in the terminal of coating in irradiation portion 11 under.Microscope carrier 12a also can irradiation portion 11 by above the terminal of coating and mobile before keeping out of the way above workpiece S1 after stop.Therefore, also can stop irradiating at the time point of irradiation portion 11 incoming terminal, also simultaneously can irradiate one side and pass through terminal.

In addition, as shown in the one-dot chain line of Figure 10 (d), exposure intensity instruction unit 73 makes the exposure intensity in irradiation portion 11 slowly reduce along with the translational speed reduction of microscope carrier 12a, by making the exposure intensity in irradiation portion 11 be elevated (change) along with the translational speed of microscope carrier 12a in short time lifting (change), the homogenising of the amount of irradiation energy also can be realized.

In addition, irradiation portion 11 and coating part 10 also can be made from time point TD to move independently.Such as, from time point TD, irradiation portion 11 starts to move to coating direction, and accelerates its speed.If make the deceleration of microscope carrier 12a identical with the absolute value of the acceleration in irradiation portion 11, then irradiation portion 11 maintains constant speed relative to the relative movement of workpiece S1.Therefore, even if because coating terminates, the relative moving speed of workpiece S1 and coating part 10 changes, the relative moving speed being coated on adhesive R on workpiece S1 and irradiation portion 11 also maintains constant speed, thus is maintained the amount of the irradiation energy of the per unit area of adhesive R.Thus, the interim hardening state of adhesive R also maintains with identical before this.In this situation, as long as irradiation portion 11 arrives the timing settings of the terminal of coating between the 1st sequential T1' and the 2nd sequential T1'.In addition, as mentioned above, irradiation portion 11 also can stop and irradiating also stopping at the time point of the terminal arriving coating, also can stop after passing through terminal and stop irradiating.

(laminating step)

As described, the workpiece S1 being coated with adhesive R to be taken out of from coating part 10 by not shown pickup device and utilizes carrying device 4 to transport, and moves into laminating apparatus 2.Herein, workpiece S2 also moves into laminating apparatus 2.As Suo Shi Fig. 7 (A), lower side panel 22 supports mounting workpiece S1 onboard.Epipleural 23 carrys out holding workpiece S2 by maintaining body.As long as the conveyance sequential of workpiece S1 and workpiece S2, carrying out adjusting in the mode of the 2-in-1 stream of laminating apparatus, is not limited to a sequential.

Such as, workpiece S2 and workpiece S1 is moved into the manufacturing installation 100 to display device component simultaneously, but this workpiece S2 also can be moved into laminating apparatus 2 by apparatus for coating 1 in advance.Then workpiece S2 is standby in laminating apparatus 2 during utilizing apparatus for coating 1 couple of workpiece S1 coating adhesive R.Or workpiece S2 also the sequential after workpiece S1 can move into manufacturing installation 100 to display device component, and moving into laminating apparatus 2 with the sequential utilizing apparatus for coating 1 to complete the workpiece S1 of coating identical.As long as take into account time that the coating to workpiece S1 spends and workpiece S2 does not produce the loss time to the moving into the spent time of laminating apparatus 2.

When having moved into workpiece S1, workpiece S2, chamber 21 has declined and has made inner airtightly then to reduce pressure, and under reduced pressure atmosphere, as Suo Shi Fig. 7 (B), is pressed by the workpiece S2 remaining on epipleural 23 fit to the workpiece S1 being supported in lower side panel 22.Laminating workpiece S1 and workpiece S2 and the laminate S10 that formed is taken out of from laminating apparatus 2 by not shown pickup device, and utilize carrying device 4 to transport and move into curing system 3.

(cure step)

As Suo Shi Fig. 8 (A), the laminate S10 utilizing carrying device 4 to transport is positioned on the microscope carrier 31 of curing system 3.Then, as Suo Shi Fig. 8 (B), illumination unit 33 irradiate make adhesive R harden completely required amount energy and complete the sclerosis of adhesive R.

In addition, the manufacturing installation 100 of display device component also can carry out other steps between the front and back of apparatus for coating 1, laminating apparatus 2 and curing system 3 or these.Therefore, the manufacturing installation 100 of display device component also can possess such as in the leading portion of apparatus for coating 1 or the leading portion shooting workpiece S1 of laminating apparatus 2, the outward appearance of workpiece S2 and carry out the position alignment portion of position alignment or the laminate S10 completed carried out to package bundle (taping) unit etc. of bale packing.In addition, also can possess at the back segment of laminating apparatus 2 position alignment portion that the workpiece S1 produced during laminating and the skew of workpiece S2 are revised or guarantee to utilize atmospheric pressure to pressurize to the hole that binding face produces and make it the standby unit etc. of the stand-by time disappeared.

In addition, also the mechanism that workpiece S1 is overturn can be set at carrying device 4, apparatus for coating 1 or laminating apparatus 2, make the workpiece S1 being coated with adhesive R overturn and remain on the epipleural 23 of laminating apparatus 2.In this situation, workpiece S2 can be positioned on lower side panel 22 and fit.Certainly, workpiece S2 also can be made to overturn and remain on the epipleural 23 of laminating apparatus 2.

[effect]

(1) according to above present embodiment, after coating adhesive R, harden to producing avalanche at this from generation tabular surface temporarily, therefore can with bending all without or be that the shape of adhesive R is fixed by state in permissible range.That is, the adhesive R of coating can be defined as suitable shape.Therefore, can fit with other workpiece under the state maintaining tabular surface.In addition, suppress by hardening temporarily because pressure during laminating causes adhesive R by situation about extruding to periphery.

In addition, the present invention can utilize following simple constitution realization, and the sequential mode become between the 1st sequential and the 2nd sequential namely arriving irradiation position with irradiation portion 11 sets the interval of irradiation portion 11 and coating part 10.In addition, irradiate sequential and irradiates sequential as long as preset the suitable top obtained by test etc. in advance with terminal, therefore control formation also becomes simple.

Consider following situation, namely do not carry out the SECO of present embodiment, but before starting coating, such as irradiation energy from the front irradiation portion 11 of the time point TA of Figure 10,11 1, irradiation portion irradiation energy one side is by the top of coating.In this situation, when irradiation portion 11 passes through the top of coating, be not limited to through the 1st sequential T1 shown in Figure 10.Therefore, likely before top is not yet planarized, by interim sclerosis, shape is fixed.In present embodiment, harden after the 1st sequential T1, therefore shape can not be fixed before planarized temporarily.In addition, when the top not setting present embodiment irradiates sequential, according to the configuration space of coating part 10 with irradiation portion 11, the situation just starting irradiation energy in microscope carrier 12a accelerates also is had.In this situation, the amount of the irradiation energy of the per unit area of adhesive R likely becomes uneven.In present embodiment, owing to being constant speed with the relative movement of microscope carrier 12a, the mode therefore by starting irradiation energy with irradiation portion 11 carries out setting and can make the amount homogenising of irradiation energy.But as above-mentioned or following, for the energy exposure in acceleration, also realize the homogenising of the amount of irradiation energy by making irradiation portion 11 and coating part 10 move independently or to adjust exposure intensity.

The viscosity of adhesive R is higher, make the 1st sequential and the 2nd sequential slower, the viscosity of adhesive R is lower, makes the 1st sequential and the 2nd sequential more early, can set the suitable sequential corresponding with viscosity thus.That is, when low viscous adhesive R, adhesive R is easy to flowing, but can solid shape rapidly by interim sclerosis.

On the other hand, when full-bodied adhesive R, the top of coating should than hardening earlier temporarily, and in the terminal of coating, the time that adhesive R on, the ledge of generation is remaining is long.Therefore, when merely irradiating top with terminal in identical sequential, fix under the state that the ledge that can produce on adhesive R in the terminal of coating is remaining.In present embodiment, before the 1st sequential that ledge disappears, wait for interim sclerosis, therefore top, terminal all can evenly be fitted.

And then, such as, when once irradiating being carried out to workpiece entirety after coating is completed to workpiece entirety and adhesive is hardened on the whole temporarily, expend time in till being applied to interim sclerosis, therefore coating top, terminal and midway, with the time through and produce change in shape respectively.In present embodiment, at top, terminal and midway the moment change coating shape, even if all can harden with suitable shape at arbitrary site, arbitrary sequence temporarily, therefore at each position can not with the time through and produce change in shape.In addition, owing to need not arrange the position of interim sclerosis in addition, therefore device can not maximize.

(2) when being such as coated with by moving of microscope carrier 12a side as present embodiment, with to the coating part 10 of lifting be coated with in the formation that the irradiation portion 11 that carries out acceleration and deceleration action in direction drives independently and then group enters compared with the situation of the formation being coated with direction movement, can formation be simplified.

(3) if use the nozzle with slit carrying out spraying from the ejiction opening of linearity as coating part 10 as present embodiment, then can easily make the thickness on the direction orthogonal with being coated with direction even, and then, utilize the mobile planar coating carried out that thickness also can be made even.

(4) coating part 10, irradiation portion 11 are maintained at constant speed all the time relative to the relative velocity of the adhesive R be coated on workpiece S1.Therefore, the amount of the irradiation energy of the per unit area of adhesive R is become fixing, therefore can not produce the uneven of interim hardening state.Thus, can prevent adhesive R from flowing, and resiliency and cohesive can be maintained, strain when therefore there is not laminating etc. and uniform adhesive layer can be formed, also can not damage cohesive in addition.And then coating part 10 makes the coating weight of adhesive R change according to the relative velocity with workpiece S1, therefore can carry out the coating of uniform thickness.

[other embodiments]

As described, adhesive shape behind the top being just coated on coating and terminal just starts to change, and produces the phenomenon of avalanche after producing par, also can produce in the edge parallel with coating direction and side.But at this side, the phenomenon of change in shape is carried out soon than top sometimes after coating.Such as there is the fireballing situation of state being changed to Fig. 5 (b), Fig. 5 (c) from Fig. 5 (a), or be changed to the fireballing situation of state of Fig. 6 (b), Fig. 6 (c) from Fig. 6 (a).

Especially, as shown in figure 13, in the terminal of coating, in the process that adhesive R is stretched, side is first separated, and middle body is finally separated.According to the above, the 2nd sequential of the side of the terminal be such as coated with also can set early than the 2nd sequential of the middle body of this terminal.

The power causing the adhesive R of the top of coating, side, terminal to change has following characteristics.

(top)

Coating part 10 one side, from the relative movement of slit ejection adhesive R one side, contacts (coating) adhesive R in workpiece S1 surface thus and is stretched by coating direction.In addition, the surface tension to the direction, top towards outer rim at top plays a role.That is, the tensile force played a role in the direction of coating part 10 relative movement is with to make tabular surface produce the capillary direction of avalanche contrary.

(side)

Described coating direction and side end face towards direction become roughly orthogonal direction, the tensile force being therefore coated with direction and the surface tension towards outer rim stagger and roughly 90 to spend.Therefore, the degree that tensile force and surface tension are cancelled out each other weakens, in the surface tension played a role towards the side direction of outer rim of side than playing a role more strongly at top.

(terminal)

Coating part 10 stops in the coating direction, and the tensile force therefore produced with the relative movement of described coating part 10 does not play a role.Coating part 10 influences each other with the surface tension intricately produced on adhesive R surface at the tensile force that direction of action applies to disconnect adhesive R.And, after adhesive R disconnects, be only applied with surface tension, but the state of change is subject to the impact producing protuberance at central portion.(with reference to Fig. 6 (a) ~ Fig. 6 (c), Figure 13).

According to the above, the 1st sequential, the 2nd sequential at side the earliest, be secondly at top, the sidepiece of terminal, be finally entreat portion in the terminal.

For realizing described various sequential, also following formation can be set to.

(1) segmentation forms irradiation portion and changes irradiation sequential

As shown in figure 14, irradiation portion 11 segmentation is configured to the irradiation portion 11A of middle body and the irradiation portion 11B of two side ends, with a part of multiple irradiation source 11a to coating position the time of advent generation time difference mode, irradiation portion 11A and irradiation portion 11B can be independently set movably.Thus, the irradiation sequential of irradiation sequential early than middle body of the side parallel with the coating direction of adhesive R is made.

(2) the irradiation sequential of multiple irradiation source is changed

As shown in figure 15, in irradiation portion 11, multiple irradiation source 11a being set along coating direction, by changing the irradiation sequential of multiple irradiation source 11a, and making the irradiation sequential of irradiation sequential early than middle body of the side parallel with the coating direction of adhesive R.If be set to this formation, then according to the change shape of adhesive R, irradiation sequential can be changed to various form.In addition, for the irradiation source 11a of Figure 15, open circles is irradiating state, and filled circles is non-irradiated state.And then, as shown in figure 16, by making the allocation position of the irradiation source 11a of side from middle body to the skew of coating direction, and the irradiation sequential of irradiation sequential early than middle body of side can be made.

As long as top irradiates sequential and terminal irradiation sequential is respectively between the 1st sequential and the 2nd sequential.1st sequential at top and the interval of the 2nd sequential, the 1st sequential of terminal and the interval of the 2nd sequential and then top irradiate sequential and terminal irradiate which time point that sequential is respectively between the 1st sequential and the 2nd sequential need not be consistent.Become between the 1st sequential at top and the 2nd sequential as long as sequential is irradiated with top in the interval in coating part 10 and irradiation portion 11, and the mode that terminal irradiates sequential to be become between the 1st sequential of terminal and the 2nd sequential sets.But also can change the interval of irradiation portion 11 and coating part 10 and the arrival sequential adjusted to terminal in coating.Such as, as shown in figure 16, in moving with constant speed, also make terminal irradiate sequential close to the 2nd sequential T2' by slowly moving in coating direction, and make by slowly moving in direction in contrast to this terminal irradiate sequential close to the 1st sequential T1'.So, by comprising the irradiation SECO to side in the irradiation SECO at top and terminal, and meticulousr shape can be defined as.

As long as adhesive R is coated with the planar needed for laminating.Such as, also can be coated with in the mode of the whole one side spreading all over workpiece S1, also can there is the region being not applied at a part.In addition, adhesive R both can arrive and also can not arrive workpiece S1 edge.Also can there is adhesive R arrive a part for workpiece S1 edge and do not arrive the part of other parts.

That is, as long as adhesive R is at least coated on the area of visual field of display unit in a planar.Such as in there is drive circuit portion at the viewing area sidepiece of display floater, not at driving circuit section coating adhesive R, but in viewing area jointlessly in planar coating adhesive.

In addition, as ejection adhesive R nozzle and to enumerate gap nozzle be that example is described, but coating part 10 is not limited to gap nozzle.Such as, also can replace gap nozzle and be set to by coating part 10 arranging the multiinjector of multiple needle-like nozzle, be multiple striated coating adhesive R by this multiinjector.Even if the adhesive R of coating extends and integration thus to become planar also identical with the coating of gap nozzle each other in multiple striated, thus planar coating can be carried out.Such as, as shown in figure 18, the adhesive R from coating part 10 be multiple striated coating, and each striped adhesive R flow and after integration, by making it interim sclerosis from irradiation portion 11 irradiation energy.

In this situation, such as, in the part except the edge on four limits that rectangular planar is coated with, namely on central portion, before the adhesive R integration of striated, the irradiation being ready to use in interim sclerosis such as to need.That is, in this situation, the 1st sequential of central portion is different from edge.Therefore, in the application's embodiment, except top, terminal, side, also the irradiation sequential of carrying out interim sclerosis irradiation is started to central portion setting.Thus, multi-jet coating also can be defined as suitable shape.

As long as the workpiece S1, the workpiece S2 that become laminating object are the component becoming laminate of formation display unit and are that planar coating adhesive R fits at one side, then its size, shape, material etc. are not limit.As long as that is, for by comprising the display floater of Polarizer etc., the touch panel, the protection panel on protection surface, the light guide plate of flat backlight or backlight etc. these at least two kinds of operation is fitted and is formed display device component.As display unit, also extensively can comprise liquid crystal display, organic el display etc. and there is the flat work of laminating and display unit that is current or that may utilize in the future.

In addition, pair of workpieces S1 bonded to each other, workpiece S2 can be 1, also can be the laminate of multi-disc.Also to can be on the laminate that display floater, drive circuit, printed base plate are fitted so laminating touch panel, protection panel or composite panel etc.That is, as display device component, the lamination number of the workpiece of lamination is not limited to certain number.

The workpiece S1 of coating adhesive R both can be the display floater of display unit or had comprised the laminate of display floater, also can be the protection panel (composite panel) protected panel, touch panel or comprise touch panel.But the strain comprising the display floater of Polarizer or colored filter etc. is large, and the individual difference of this strain is also large.As only protected should diminishing of simple constitutor as panel, only touch panel or these composite panel, coating adhesive R equably can be easy to.In addition, also require to suppress adhesive R flowing when fitting the light guide plate etc. of flat backlight or backlight and prevent hole.That is, backlight or light guide plate also can be regarded as workpiece S1, workpiece S2.Adhesive R also can be coated in any one in laminate, backlight, light guide plate, but in this situation, is preferably coated on the backlight of simple formation, light guide plate side.

In addition, also can on fitted workpiece S1, both workpiece S2 coating adhesive R.When to workpiece S1, both workpiece S2 coating adhesive R, the adhesive R be coated in one both only can be made to harden temporarily, the adhesive R be coated on both also can be made temporarily to harden.When to both coating adhesive R, both apparatus for coating can be set respectively, also workpiece S1, both workpiece S2 sequentially can be fed in 1 apparatus for coating.

Be not by microscope carrier 12a, workpiece S1 side is moved, but make coating part 10 and side, irradiation portion 11 move to be coated with yet.In this situation, when coating part 10 accelerates and when slowing down, slow down by irradiation portion 11 independently with coating part 10 and accelerate, also identical can maintain constant speed with described.

Irradiation portion 11 as described in as illustration, also make the amount of the irradiation energy of the per unit area of adhesive R be fixing by making exposure intensity change.That is, when coating part 10 accelerates with the relative moving speed of workpiece S1, the amount of irradiation energy is slowly increased, makes when relative moving speed is fixing the amount of irradiation energy be fixing, and when relative moving speed slows down, the amount of irradiation energy is slowly reduced.Thus, evenly need not maintain the relative moving speed of irradiation portion relative to workpiece S1 to make irradiation energy, and irradiation portion 11 can independently need not be formed movably relative to coating part 10, therefore can form by simplification device further.

The change of the amount of this irradiation energy not only makes luminescence (output) Strength Changes of each irradiation source 11a in irradiation portion 11 realize by exposure intensity instruction unit 73, the number change of the irradiation source 11a also irradiated by the carrying out made in multiple irradiation source 11a realizes.Such as, presence or absence or luminescence (output) intensity of the luminescence (output) of the multiple irradiation source 11a be configured on the long side direction in irradiation portion 11 is controlled.In addition, also by being set to utilize elevating mechanism to be elevated irradiation portion 11, and the exposure intensity, irradiating width etc. that utilize exposure intensity instruction unit 73 to control its lifting and adjust irradiation portion realize.

The formation in irradiation portion 11 is not limited to the formation being arranged with multiple irradiation source 11a.Also by utilizing fiber guides, from the light of the irradiation source 11a independently formed separately with microscope carrier 12a, the front end of this optical fiber is configured to irradiation portion 11.In addition, irradiation portion 11 also can possess the optical component making it to irradiate in the wire parallel with the slit of coating part 10.As optical component, such as, collector lens, slit etc. can be applied.Exposure intensity, except the intensity by adjustment irradiation source 11a adjusts, also adjusts by this optical component.Irradiating widths etc. also adjust by this optical component.In addition, the shielding portion such as shutter (shutter), mask optionally changing range of exposures can also be possessed.

Also irradiation portion 11 can be set to the device of point-like irradiation energy, and this irradiation portion 11 is set to carries out by sweep mechanism the formation that scans along parallel with the slit of coating part 10 (with orthogonal direction, coating direction) or the direction that is similar to this.In this situation, also by irradiation timing settings is maintained tabular surface between described 1st sequential and the 2nd sequential.

In addition, as described in as illustration, also make irradiation energy be fixing by making exposure intensity change.That is, when coating part 10 accelerates with the relative movement of workpiece S1, the exposure intensity in irradiation portion 11 is increased, and at relative moving speed for making exposure intensity be fixing time fixing, when relative movement is slowed down, exposure intensity is reduced.Thus, the irradiation energy of the per unit area on irradiated site also can be made to be fixing.And then, also by making multiple irradiation source 11a replace making irradiation portion 11 move in coating direction sequentially luminescence.Thus, the simplification of mechanism can be realized.

As long as make being spaced apart of irradiation portion 11 and coating part 10 produce tabular surface at the binding face of adhesive R and the interval irradiated can be started before producing avalanche, then also continuation can continue to irradiate when not making irradiation temporarily stop.When not being strict with the homogenising of irradiation energy, irradiate sequential and terminal irradiate sequential as long as can set top as described, then the control of coating part 10, microscope carrier 12a is not limited to the form of described speeds control, spray volume control.

The support of workpiece S1 on the microscope carrier 12a of the adhesive coating device 1 or all maintaining body that in the future may utilize current by vacuum chuck, electrostatic chuck, mechanical chuck, bonding chuck etc. and make it stabilisation.Also can and use multiple maintaining body.

The kind of the adhesive R used is not limited to uv-hardening resin.Generally by the resin irradiating electromagnetic wave or heat and sclerosis, but all adhesives that are current or that may utilize in the future can be used and be the adhesive hardened by irradiation energy.In this situation, according to the kind of adhesive, irradiation portion can be changed to the irradiation unit, heater, drying device etc. of various infrared ray, radioactive ray etc.
