Description

Subsequent agent supply device and adhesive supply method

The present invention relates to, for example, an adhesive supply device and an adhesive supply method obtained by modifying a technique in which a pair of workpieces constituting a display device are bonded together, and an adhesive is supplied to a workpiece.

In general, a liquid crystal display (module), a touch panel for operation, and a protective panel (cover panel) for protecting a surface are laminated to form a liquid crystal display (display). . The liquid crystal module, the touch panel, the protective panel, and the like (hereinafter referred to as a workpiece) are frames that are incorporated in the liquid crystal display.

In order to bond the above-mentioned workpieces, a method of using a sheet and a method of using a resin adhesive have been known. Next, the sheet is higher in price than the adhesive, and a step of peeling off the paper or the like is required. Therefore, according to the demand for cost reduction in recent years, etc., the sticking using the adhesive agent is the mainstream.

Further, when the air layer enters between the stacked workpieces, the visibility of the display surface of the liquid crystal is lowered by the external light reflection. In order to cope with the above, when the workpieces are bonded together, the gaps between the workpieces (gap) are filled by an adhesive to form an adhesive layer.

The above-mentioned adhesive layer functions as a spacer between the workpieces and protects the workpiece. Moreover, the size of the workpiece is also increased due to the increase in size of the liquid crystal display, and the deformation is likely to occur. Therefore, in order to Absorbing and protecting the workpiece, there is a tendency for the thickness of the layer to increase. For example, a thickness of several hundred micrometers (μm) is required.

To ensure the above thickness, the amount of the necessary adhesive will increase. As a result, the adhesive supplied to the workpiece flows, so that it is easy to overflow from the workpiece. Therefore, a method of using a resin having a low viscosity and a high viscosity is considered. However, even in the above case, if the process conditions such as the application position of the adhesive are not closely adjusted, there is a case where the adhesive overflows from the predetermined region when the bonding is performed.

In order to cope with this, there is a seal method in which a seal is formed on a predetermined outer circumference of a coating region by a high-viscosity resin or a pseudo-curing resin (see Patent Document 1). The adhesive of the resin is applied to the workpiece in a frame shape, and the adhesive is pseudo-hardened, whereby a seal is formed, and an adhesive of the resin is filled to the inside to bond the workpiece. In the sealing method described above, since the seal is present on the outer circumference, it is possible to prevent the overflow due to the flow of the adhesive at the time of bonding.

However, there is a possibility that a boundary remains between the seal formed by the above sealing method and the adhesive filled in the inside. For example, in a display device such as a liquid crystal display, if the boundary between the first cured seal and the internal adhesive enters the field of view of the user, the visibility of the screen is hindered. However, according to the requirements of the enlargement of the screen, The requirement for miniaturization of the member itself makes it difficult to sufficiently secure the space for the seal outside the field of view of the workpiece.

Further, for example, if the adhesion of the adhesive of the sealing member is excessively promoted, the adhesive may lose cushioning or adhesion. As a result, when the bonding is performed, there is a possibility that the upper and lower workpieces do not match, and the uniformity of the thickness of the bonding is impaired.

The present invention has been made to solve the above problems of the prior art, and an object of the present invention is to provide an adhesive supply device and an adhesive supply method which are capable of preventing the adhesive supply device and the adhesive supply method. The flow of the agent then ensures a uniform fit thickness.

In order to achieve the above object, the present invention is an adhesive supply device that supplies an adhesive to at least one of a pair of workpieces constituting a display device, the adhesive supply device including: a supply portion to face In a form of spreading, the adhesive is supplied to one surface of the workpiece, and the dummy hardening portion is subjected to false hardening by a part or all of the supplied adhesive in accordance with the supply by the supply unit.

In the invention as described above, the adhesive is supplied to one side of the workpiece in a planar manner, and the adhesive is pseudo-hardened. Therefore, the flow of the adhesive is suppressed, and the coating shape can be prevented from being aliased. Or it may prevent the above-mentioned adhesive from overflowing toward the outside of the workpiece. Further, since the above-mentioned adhesive is pseudo-hardened during the supply process, the process time (tact time) can be shortened. Moreover, the cushioning property and adhesiveness of the adhesive are maintained by the pseudo hardening. Therefore, there is no problem with the adhesion at the time of bonding, and a uniform fit can be ensured. thickness. Moreover, since there is no boundary in the adhesive, the visibility of the field of view in the display device is not impaired. Moreover, it is not necessary to separately prepare and supply the adhesive for forming the seal and the adhesive for internal filling after the unit for the seal is provided, so that the process time can be shortened and the cost can be saved.

In another aspect, the pseudo-hardening processing unit is provided to be movable together with the supply unit.

In the above-described embodiment, the pseudo-hardening treatment portion is moved together with the supply portion, whereby the pseudo-hardening can be performed in accordance with the supply of the adhesive.

In another aspect, the pseudo-hardening processing unit is provided to be movable independently of the supply unit.

In the above-described form, it is possible to move by being independent of the supply portion, and the desired range can be pseudo-hardened. Further, the pseudo hardening can be performed according to an appropriate timing according to the dispersion of the supplied adhesive.

In another aspect, the adhesive agent is an adhesive that is cured by irradiation with electromagnetic waves, and the pseudo-curing treatment unit includes an irradiation unit that irradiates electromagnetic waves to the adhesive.

In the above-described form, the pseudo hardening can be easily performed by the irradiation of the irradiation portion.

In another aspect, the adhesive agent is an ultraviolet curable resin, and the irradiation unit includes an ultraviolet irradiation device that irradiates ultraviolet rays to the adhesive in the atmosphere.

In the above-described form, ultraviolet rays are irradiated to the atmosphere, whereby the pseudo-hardening can be easily achieved by oxygen suppression or the like.

In other forms, the irradiation range of the electromagnetic wave is variably set.

In the above-described form, only the desired region can be pseudo-hardened by changing the irradiation range.

Furthermore, it is also possible to grasp the above-described respective aspects as an invention of the adhesive supply method.

As described above, according to the present invention, it is possible to provide an adhesive supply device and an adhesive supply method which can prevent the flow of the adhesive and ensure a uniform bonding thickness.

The embodiment (hereinafter referred to as an embodiment) of the present invention will be specifically described with reference to the drawings.

[A. Composition]

First, the configuration of the adhesive supply device (hereinafter referred to as the present device) of the present embodiment will be described. As shown in FIGS. 1(A) to 1(B) and FIGS. 2(A) to 2(B), the device includes an adhesive supply unit 1, a bonding unit 2, and the like. The workpieces S1 and S2 to be bonded together are, for example, a workpiece constituting a display device such as a touch panel of a liquid crystal display and a protective panel. Further, the workpiece S1 is provided to be movable between the adhesive supply unit 1 and the bonding unit 2 by the conveying unit 3.

As the adhesive used in the present embodiment, for example, an ultraviolet (UV) curing resin can be considered. The adhesive supply unit 1 includes a supply unit 10, a pseudo-hardening unit 11, and the like. For example, the supply department 10 includes a dispenser that drops the adhesive R accommodated in the tank T to the workpiece S1 via a pipe. For example, the dispenser is configured to be movable by a scanning device (not shown).

For example, the pseudo-hardening treatment unit 11 includes an irradiation unit that irradiates UV light from a UV light source (not shown) to the adhesive R via an optical fiber. Furthermore, the illuminating unit itself can also be used as a light source.

For example, the irradiation unit includes an optical member that is irradiated in a dot shape or a thin line shape. For example, a condensing lens, a slit, or the like can be applied as the optical member. In addition to adjusting the intensity of the illumination by adjusting the intensity of the light source, the illumination intensity can also be adjusted by the optical member described above. The irradiation aperture, the irradiation width, and the like can also be adjusted by the optical member.

The irradiation unit is irradiated in the atmosphere to cause the curing of the adhesive R to be pseudo-hardened by oxygen inhibition or the like (a state in which an unhardened portion such as semi-hardening remains is widely included).

The hardening treatment unit 11 is attached to the supply unit 10, for example, and is movable in the supply direction of the adhesive R as the supply unit 10 moves. Further, the pseudo-hardening processing unit 11 is provided to be movable in a direction orthogonal to the moving direction (supply direction) of the supply unit 10 by a scanner (not shown). The pseudo-hardening treatment unit 11 is provided so as to be movable up and down by the scanner or the elevating mechanism, and the irradiation intensity, the irradiation aperture, the irradiation width, and the like of the irradiation unit can be adjusted by the above-described raising and lowering.

As shown in FIGS. 2(A) and 2(B), the bonding unit 2 includes a bonding apparatus 20 that bonds the workpiece S2 to the adhesive R of the workpiece S1. For example, the bonding device 20 includes a vacuum chamber 21, a pressing device 22, and the like.

The vacuum chamber 21 is a chamber that covers the periphery of the workpieces S1 and S2 to be bonded, and seals a portion between the workpieces S1 and S2 to form a vacuum chamber. A vacuum pump (not shown) as a vacuum source (pressure reducing device) is connected to the vacuum chamber 21 via a pipe. Further, the vacuum chamber 21 is provided to be movable up and down by an elevating mechanism (not shown).

The pressing device 22 is a device that presses the workpiece S2, thereby bonding the workpiece S2 to the workpiece S1. For example, the pressing device 22 includes a holding portion that holds the workpiece S2, an elevating mechanism that moves the holding portion up and down, and the like.

The transport unit 3 includes a transport device 30 that transports the workpiece S1 from the adhesive supply unit 1 toward the bonding unit 2 . As the conveying device 30, for example, a turntable, a conveyor, and the like, and a drive mechanism thereof can be considered. However, any device may be used as long as it can transport the workpiece between the above parts. The conveyance device 30 conveys the workpiece S1 in a state of being placed on the placing unit 31.

[B. Function]

The operation of this embodiment having the above configuration will be described with reference to Fig. 1 (A) and Figs. 1(B) to 5 . Further, the positions and angles of the pseudo-hardening portion 11 in FIGS. 3(A) and 3(B) are merely simple displays for explaining the action.

First, as shown in FIG. 1(A) and FIG. 1(B), the conveying device 30 is From the previous step, the workpiece S1 placed on the placing portion 31 is transferred to the adhesive supply unit 1. In the adhesive supply unit 1, as shown in FIGS. 1(A) and 3(A), the supply unit 10 is a surface in which the adhesive R is supplied to the workpiece S1 in a planar manner.

For example, as shown in FIG. 4, the adhesive R is supplied (coated, dripped) from the nozzle of the dispenser to the workpiece S1. The dispenser is moved by the scanning device, whereby the supply of the adhesive R is started so as to extend over a wide area of the workpiece S1.

Further, the adhesive R may be applied as long as it is in the desired planar shape. For example, the coating may be applied over the entire surface of the workpiece, or a portion of the uncoated region may be present. Further, even when the coating is performed "over the whole", it is not always necessary to completely reach the edge of the surface. Even if there is a portion where the adhesive does not slightly reach the edge, it may be referred to as an adhesive throughout the whole.

For example, as in the side of the workpiece S2 of Fig. 5 described below, even if the adhesive R does not slightly reach the edge of the surface, it is included in the concept of "overall". That is, for example, even in the end portion of the adhesive R supplied to the workpiece S1, the state of the relationship between the edge of the workpiece S2 of FIG. 5 and the end of the adhesive R may be referred to as "overall".

The pseudo-hardening treatment portion 11 that moves together with the supply unit 10 is to gradually irradiate the UV light to the adhesive R from the irradiation portion. For example, the pseudo-hardening treatment unit 11 moves toward the application direction simultaneously with the supply unit 10, and reciprocates in a direction orthogonal to the application direction by the scanning device. Thereby, as shown in FIG. 1(B), FIG. 3(B), and FIG. 4, UV light is used. The entire surface of the applied adhesive R is gradually irradiated.

Since the UV light is irradiated in the atmosphere, the progress of the hardening is slowed by oxygen suppression or the like, and the pseudo-hardened portion H in an appropriate pseudo-hardened state can be obtained. In this manner, the entire adhesive R is supplied to the end portion of the workpiece S1, and the entire supplied adhesive R is set as the dummy hardened portion H.

Then, the transport device 30 transports the workpiece S1 to which the adhesive R is supplied to the bonding unit 2. In the bonding unit 2, as shown in FIG. 2(A), the workpiece S2 is held by the pressing device 22, and the vacuum chamber 21 is lowered to seal the periphery of the workpieces S1 and S2. Next, the pressure reducing pump is operated, whereby the pressure reduction (exhaust) in the vacuum chamber 21 is started.

After the evacuation is completed, the pressing device 22 is lowered, whereby the workpiece S2 is pressed against the workpiece S1 (Fig. 2(B)). At this time, since the entire adhesive R becomes the pseudo-hardened portion H, the flow caused by the pressing is suppressed, and on the other hand, the entire adhesive R maintains the cushioning property. Therefore, the strain or the like at the time of bonding is absorbed, so that the uniformity of the thickness of the bonding can be achieved. Further, since the dummy hardened portion H maintains the adhesion of the surface, there is no problem with the adhesion of the workpiece S2.

Then, the vacuum is broken by the opening of the exhaust path or the like, and the vacuum chamber 21 is raised, whereby the bonded workpieces S1 and S2 are in the atmosphere. Further, the transport device 30 carries the workpieces S1 and S2 from the bonding unit 2 to the next step. For example, the conveying device 30 moves the workpieces S1 and S2 to the curing portion, which is used to cure the adhesive R by the irradiation of UV light.

[C. Effect]

According to the embodiment as described above, the following effects can be obtained. fruit. In other words, the adhesive R is supplied so that one surface of the workpiece S1 is dispersed in a planar manner, and the adhesive R is formed into the pseudo hardened portion H. Therefore, the flow of the adhesive R can be prevented. Moreover, since the pseudo-hardened portion H is formed with the supply of the adhesive R, the process time can be shortened as compared with the case where the hardening treatment is performed after the coating is completed. Further, since the pseudo-hardened portion H maintains the cushioning property, strain or the like at the time of bonding is absorbed, and a uniform adhesive layer can be formed.

After the same adhesive R is supplied to the entire surface, the entire surface is set as the dummy hardened portion H. Therefore, for example, as shown in FIG. 5, the boundary does not remain in the visual field range W of the user, and the screen is not present. The visibility of the image has an impact. It is not necessary to separately prepare and supply an adhesive for sealing and an adhesive for internal filling, and therefore, in this respect, the process time can be shortened and cost can be saved.

Further, for example, generally, when vacuum bonding is performed, there is a case where the speed of evacuation is lowered due to the outgas generated by the unhardened adhesive R. However, in the present embodiment, since the adhesive R is set as the pseudo-hardened portion H, generation of the escape gas can be suppressed, and the speed of evacuation can be prevented from being lowered.

[D. Other embodiments]

The present invention is not limited to the embodiments described above. For example, the dummy hardening processing unit 11 is provided so as to be movable independently of the supply unit 10 by the scanning device, whereby the application and the false curing of the adhesive R can be alternately performed.

For example, as shown in FIG. 6(A), the supply unit 10 moves by a predetermined amount and will After the application agent R is applied to the workpiece S1, it is temporarily stopped. Then, as shown in FIG. 6(B), the irradiation portion of the pseudo-hardening treatment portion 11 is irradiated with the applied adhesive R while moving the UV light, whereby the adhesive R is set as the pseudo-hardened portion H. .

Next, as shown in FIG. 6(C), the supply unit 10 is moved by a predetermined amount, and after the application agent R is applied to the workpiece S1, it is temporarily stopped. Then, as shown in FIG. 6(D), the irradiation portion of the pseudo-hardening treatment portion 11 is irradiated with the applied adhesive R while moving, and the adhesive R is set as the pseudo-hardened portion H. .

The above steps are repeated, whereby the adhesive R can be supplied to the workpiece S1, and the pseudo hardened portion H can be formed. Thereby, the adhesive R can be pseudo-hardened in the following state, which means that the dispersion of the adhesive R is stabilized to some extent after the supply of the adhesive R.

Further, as shown in FIG. 7(A), FIG. 7(B), and FIG. 8(A) to FIG. 8(D), it is conceivable to use the following bar-shaped irradiation unit in the pseudo-hardening processing unit 11 The long-shaped irradiation portion is irradiated with UV light in a line shape. In FIGS. 7(A) and 7(B), similarly to FIGS. 3(A) and 3(B), the pseudo-hardening treatment unit 11 moves together with the supply unit 10 and emits UV light. Thereby, the driving portion can be reduced, and the application and the pseudo hardening of the adhesive R can be performed at high speed.

8(A) to 8(D) are examples in which the long-shaped irradiation device, that is, the pseudo-hardening processing portion 11, is provided by the scanning device so as to be independent of the supply portion. 10 ways to move. According to this aspect, similarly to FIGS. 6(A) to 6(D), it is possible to alternately Coating and pseudo hardening are carried out. Even in this case, irradiation of UV light for pseudo hardening can be performed at high speed.

Further, as shown in FIGS. 6(A) to 6(D) and FIGS. 8(A) to 8(D), the pseudo-hardening processing unit 11 is provided so as to be movable independently of the supply unit 10. At the time, or when the interval between the pseudo-hardening treatment portion 11 and the supply portion 10 is increased, there is a time difference between the coating and the pseudo-hardening. For example, the supply unit 10 continuously supplies (continuously) the adhesive R, and the adhesive R is continuously (continuously) pseudo-hardened by the pseudo-hardening treatment portion 11, and the supply of the adhesive R is continuously provided. The time difference from the start of the pseudo hardening of the pseudo-hardening treatment portion 11 is started, whereby the adhesive R can be pseudo-hardened after the adhesive R is sufficiently dispersed in a planar shape.

Further, as shown in FIGS. 9(A), 9(B) to 12(A) and 12(B), the pseudo-hardened portion H can be formed in a part of the adhesive R to prevent the flow of the adhesive R. For example, FIG. 9(A) and FIG. 9(B) are forms in which an adhesive is supplied by the supply unit 10, and a plurality of (may be single) pseudo-hardening treatment portions 11 are provided along the adhesive. The edge of the coated region of R moves and emits UV light. Thereby, the edge of the coating region can be made into a frame-shaped pseudo-hardened portion to prevent the flow.

Further, there is also a form in which the long-shaped pseudo-hardening treatment portion 11 is used. For example, as shown in FIG. 10(A), the irradiation range of the UV light of the pseudo-hardening treatment portion 11 is performed so as to extend the entire width of the application region around the start end and the end end of the application region of the adhesive R. set up. As shown in FIG. 10(B), the setting between the start end and the end end is performed only by irradiating both ends of the application region.

It is possible to control the irradiation region as described above by controlling whether or not a plurality of light sources arranged in the longitudinal direction of the strip emit light or whether the illuminating portion emits light. Further, the irradiation region as described above may be changed by providing a shielding portion such as a shutter or a mask, and the shielding portion may selectively change the irradiation range. Thereby, the edge of the application region of the adhesive R can be made into a frame-shaped pseudo-hardened portion H to prevent the flow.

Further, the dummy hardened portion H does not necessarily have to be formed in a frame shape. As shown in FIGS. 11(A) to 11(D), even if it is formed on the edge of at least a part of the application region of the adhesive R, the effect of preventing the flow can be obtained.

As a result, the region in which the pseudo-hardened portion H is formed by the irradiation of electromagnetic waves can be set to a very narrow range. Thereby, the boundary between the pseudo hardened portion H and the uncured portion can be made outside the field of view W shown in FIG.

Further, as shown in FIG. 12(A) and FIG. 12(B), the pseudo-hardened portion H may be formed in a plurality of lines, a plurality of dots, or the like in the application region. This can be achieved in such a manner that the irradiation is performed every time the irradiation portion of the pseudo-hardening processing portion 11 of FIG. 4 moves, or the elongated irradiation portion of FIGS. 7(A) and 7(B) is used. The timing of illumination or shading is controlled. Even in this case, only a part of the same adhesive which is simultaneously supplied in a planar shape is pseudo-hardened, so that a boundary which can be seen is hardly left.

The form of the pseudo-hardening may be pseudo-hardened into a specific shape such as a square, a circle, an ellipse, another polygon, and a curved circle, or may be pseudo-hardened discretely. The area of false hardening does not necessarily constitute a closed area area. As described above, it may be linear, or may be curved or curved.

In the present invention, "false hardening is performed along with the supply by the supply unit", and at least the period from the start of the supply of the adhesive to the end of the supply (during the supply) is started. Just handle it. The adhesive may be supplied to one surface of the workpiece in a planar manner, and the adhesive may be supplied to the entire surface of the workpiece or may be supplied to a part of one surface of the workpiece.

In addition, the configuration and supply method of the supply portion of the adhesive may be applied so as to extend over one surface of the workpiece in a planar manner. When the supply unit is scanned and applied in a line shape, it is freely moved in any manner, for example, moving up and down, moving forward and backward, and moving rotationally. As shown in FIG. 13, the supply part 10 may apply the adhesive agent R in a plurality of lines. In this case, a plurality of independent dispensers can also be connected. Further, various devices such as a device for coating by a roller, a device for coating by a squeegee, and a device for performing spin coating can be applied.

The type of the adhesive to be used is not limited to the ultraviolet curable resin. Generally, a resin which is hardened by electromagnetic waves or heat irradiation is applied, and all of the adhesives which can be used now or in the future can be applied. In this case, the pseudo-hardening treatment unit is changed to an irradiation device, a heating device, a drying device, or the like depending on the type of the adhesive.

Further, all the methods and devices that can be used currently or in the future can be applied to the bonding unit and the transport unit. For example, regarding the bonding portion, the structure in which the workpiece is held may be, for example, a mechanical chuck or a static electricity. Any configuration of chucks, vacuum chucks, and adhesive chucks. The space for vacuum bonding may be a structure in which the lower member is lifted and lowered to be closed and opened, or a structure in which only the passage of the workpiece is opened and closed. Further, a vacuum bonding device is not necessarily used, and a device for bonding in the atmosphere may be used.

The conveying device may be, for example, any structure such as a turntable, a conveyor belt, a feeding mechanism, or the like. For example, a susceptor or the like may be used as the mounting portion. However, any material or shape may be used as long as it functions as a support that can support the workpiece. It is not limited to support in the horizontal direction. The method of transferring the workpiece is not limited to the case of being placed on the placing portion. It can also be placed directly on the mobile station. Furthermore, it is also possible for the worker to use a manual operation to move the workpiece.

In addition, the workpiece to be bonded is a workpiece that forms a display device like a cover panel and a liquid crystal module, and the adhesive is applied to one surface and bonded to each other, regardless of the size or shape of the workpiece. And materials, etc. Not only can it be applied to the case where the adhesive is supplied to one workpiece, but it can also be applied to the case where the adhesive is supplied to two workpieces. In this case, when the adhesive is supplied to the two workpieces, only the adhesive of one workpiece may be pseudo-hardened, and the adhesive of both workpieces may be pseudo-hardened.
