Description
Technical Field
The present invention relates to an adhesive sheet sticking apparatus and a sticking method for sticking various adhesive sheets such as a polarizing plate to a substrate such as a liquid crystal panel.
Background
Conventionally, a device in which a polarizing plate is attached to a liquid crystal panel is known. When the polarizing plate is attached to a liquid crystal panel, it is necessary to prevent wrinkles or air bubbles from being mixed in accordance with recent demands for higher definition of a liquid crystal display (for example, patent document 1).
Patent document 1 discloses a film sticking apparatus that holds a polarizing film (corresponding to a polarizing plate, hereinafter referred to as a polarizing plate) on the outer peripheral surface of an annular absorbent sheet that is stretched between a plurality of rollers, and presses and adheres the polarizing plate to a liquid crystal panel via the absorbent sheet while moving the absorbent sheet.
According to the device of patent document 1, when the polarizing plate is attached to the liquid crystal panel, the absorption force of the absorption sheet in the traveling direction is not so strong and the polarizing plate has flexibility, and therefore the polarizing plate is not damaged by friction with the absorption sheet. In addition, when the polarizing plate is attached to the liquid crystal panel, the polarizing plate is held on the absorbent sheet until just before the attachment, and therefore, bubbles can be prevented from being mixed and wrinkles can be prevented from being generated.
Also, a sticking device is known which holds both ends of a holding sheet (corresponding to the adsorption sheet) having a predetermined length in advance, holds a polarizing plate on the holding sheet, and holds one end of the holding sheet so as to be controllable at a predetermined angle (for example, patent document 2).
In the device of patent document 2, as in patent document 1, the polarizing plate is held until the substrate is to be bonded, and therefore, bubbles and wrinkles can be prevented. In addition, since the polarizing plate can be held at a predetermined angle when the polarizing plate is attached to the liquid crystal panel, air bubbles can be prevented from being mixed.

Problems to be solved by the invention
However, in the device of patent document 1, the absorption sheet holding the polarizing plate is formed in a ring shape. Therefore, there are problems as follows: when a plurality of polarizing plates are attached to a liquid crystal panel, the absorption sheet is stretched, and the holding position of the polarizing plates becomes unstable, which lowers the attachment accuracy.
In addition, there are problems as follows: since the adsorption sheet is elongated, the adsorption sheet is wrinkled when the polarizing plate is adsorbed, and defective adhesion occurs. In addition, there are problems as follows: since the suction sheet stretches, the tension of the suction sheet changes, which affects the bonding accuracy, or the adjustment of the apparatus becomes complicated because the tension needs to be adjusted.
Moreover, there are problems as follows: when the suction sheet is manufactured, it is necessary to manufacture the circumferential length of the suction sheet with high accuracy, and it takes time to adjust the circumferential length for forming the ring shape, or it takes cost to form the ring shape from the beginning. In addition, there are problems as follows: when the suction sheet is replaced, it is necessary to pass the suction sheet through all the guide rollers (guide rollers), and it takes time to replace the suction sheet.
In addition, there are problems as follows: if dust or dirt adheres to the adsorption sheet, the holding force of the adsorption sheet is reduced, and the polarizing plate cannot be stably adsorbed and held, resulting in poor adhesion.
The device of patent document 2 uses a holding piece having a predetermined length, and has the following problems as in the device of patent document 1: if dust or dirt adheres to the holding sheet, the holding force is reduced, and poor adhesion occurs.

According to the first holding mechanism 53 and the second holding mechanism 65, when the supply roller unit 54 and the recovery roller unit 66 are replaced, the supply roller unit 54 can be easily attached to and detached from the first holding mechanism 53, and the recovery roller unit 67 can be easily attached to and detached from the second holding mechanism 65.
The above description is of the adhesive sheet joining apparatus 6 of the present invention and the liquid crystal panel manufacturing apparatus 1 to which the adhesive sheet joining apparatus 6 is applied. Next, the operation of attaching the adhesive sheet S to the substrate P by the adhesive sheet attaching device 6 using the liquid crystal panel manufacturing apparatus 1 will be described below with reference to fig. 1, 4(a) to 4 (g).
As shown in fig. 1 and 4(a), the adhesive sheet S is taken out one by one from the adhesive sheet supply section 17 by the carrier 8a, and the adhesive sheet S with the separator 16 temporarily attached to both surfaces thereof is carried to the peeling table 10. The release tape 11 is wound around the release table 10 so that the adhesive surface is an upper surface, and the adhesive sheet S is placed on the release tape 11.
Next, as shown in fig. 4(b), the adhesive sheet sticking apparatus 6 moves onto the adhesive sheet S. After the adhesive sheet sticking device 6 faces the adhesive sheet S, the roller frame 73 is positioned at the front end portion (right side in the drawing) of the peeling table 10. Next, the roller frame 73 is lowered, the application roller 51 is pressed against the front end portion of the adhesive sheet S via the holding sheet 13, and the application roller 51 is rolled toward the rear end portion (left side in the figure) of the adhesive sheet S, whereby the separator 16 of the adhesive sheet S is applied to the release tape 11. Further, as the separator 16 is attached to the release tape 11, the holding sheet 13 is pressed against the separator 16 on the front surface side of the adhesive sheet S, whereby the adhesive sheet S is held by the holding sheet 13.
Next, as shown in fig. 4 c, the peeling table 10 is retracted (in the left direction in the figure), and the peeling tape 11 is wound around an appropriate recovery roll (not shown), whereby the separator 16 temporarily attached to the adhesive sheet S is peeled.
As shown in fig. 4(d), the adhesive sheet S from which the separator 16 has been peeled off is held by the holding sheet 13 having adhesiveness.
Simultaneously with the holding operation of holding the adhesive sheet S on the holding sheet 13, as shown in fig. 1, a substrate P is conveyed from the previous step by the supply conveyor 3, rotated by 90 ° by an appropriate mechanism, and then placed on the substrate supply portion B of the index table 5 a. The substrate P is positioned on the index table 5a by an appropriate positioning mechanism.
Next, the operation of attaching the adhesive sheet S to the substrate P will be described with reference to fig. 4(e) to 4 (g).
When the substrate P positioned on the index table 5a is positioned at the bonding section C as shown in fig. 1, the adhesive sheet bonding apparatus 6 moves onto the substrate P so that the adhesive sheet S held by the holding sheet 13 is positioned opposite to the substrate P as shown in fig. 4 (e).
As shown in fig. 4(f), the joining roller 51 is lowered to press the adhesive sheet S to one end of the substrate P via the holding sheet 13.
Next, as shown in fig. 4 g, the joining roller 51 moves integrally with the peeling roller 52 toward the other end side (in the right direction in the figure), whereby the adhesive sheet S is joined to the substrate P and the adhesive sheet S is separated from the holding sheet 13.
Every time a predetermined number of adhesive sheets S are attached to the substrate P, the tape pressing member 60 is released from pressing, a predetermined amount of the holding sheet 13 is fed out from the supply roller 55, and the holding sheet 13 is wound around the recovery roller 67. The holding piece 13 is fed out and wound up automatically or manually.
Next, as shown in fig. 1, after the index table 5a is rotated by 90 °, the substrate P to which the adhesive sheet S has been attached is positioned in the substrate discharge section D, the substrate P is taken out by an appropriate carrier (not shown), and is inverted vertically by an appropriate inversion mechanism (not shown), and the substrate P inverted vertically is conveyed to the substrate supply section B of the index table 5B on the downstream side.
The adhesive sheet S is attached to the back surface side of the substrate P on the downstream-side index table 5b, but the explanation thereof is omitted because the same mechanism as that on the upstream side is used.
The substrate P having the adhesive sheets S bonded to both surfaces thereof is positioned in the substrate discharge section D by the index table 5b rotating 90 °, and is placed on the discharge conveyor 4 by an appropriate conveyance mechanism (not shown) and conveyed to the next step.
The above is an embodiment of the adhesive sheet sticking apparatus of the present invention, and next, an adhesive sheet sticking apparatus of a second embodiment of the present invention will be described below with reference to fig. 5, 6, and 9. The same reference numerals are used for the same components as those in the first embodiment.
The bonding operation of the bonding sheet bonding apparatus 6 according to the second embodiment for bonding the bonding sheet S to the substrate P is similar to that of the first embodiment, and relates to an exchange unit and an exchange method for the holding sheet 13.
Fig. 5 is a plan view of the adhesive sheet sticking apparatus 6 to which the replacing unit 74 as the holding member of the holding sheet 13 is attached according to the second embodiment, and fig. 6 is a front view. Fig. 9 is a perspective view showing a state in which the replacement unit 74 is removed from the adhesive sheet sticking apparatus 6, and the supply roller unit 54 and the recovery roller unit 66 are removed (for convenience of explanation, they are drawn upside down).
The replacement unit 74 includes two holding plates 70, a supply roller unit 54 held at one end side between the two holding plates 70, a recovery roller unit 66 also held at the other end side between the two holding plates 70, engaging members 71, 72 provided at both ends of the holding plates 70, and the like.
As shown in fig. 6 and 9, the holding plate 70 is provided with an opening 70a, an opening 70b, and a relief hole 70c for reducing the weight or preventing interference. The supply roller unit 54 and the recovery roller unit 66 are held by the two holding plates 70 by the engaging members 71 and 72.
The engaging member 71 includes an engaging pin that protrudes or retracts in the outer circumferential direction of the shaft, and the engaging pin protrudes or retracts from the shaft by rotating the handle. After the shaft of the engaging member 71 is inserted into the engaging hole 57a (see fig. 9) of the supply roller unit 54, the engaging pin protruding by turning the handle is engaged with an engaging portion (not shown) in the engaging hole 57a, and the support frame 57 is fixed to the holding plate 70. At this time, the supply roller shaft portion protruding from the support frame 57 is retracted to the retraction hole 70c, and does not interfere with the holding plate 70.
The supply roller unit 54 can be attached to or detached from the holding plate 70 by turning the handle of the engaging member 71 to the left or right.
The engaging member 72 has the same configuration as the engaging member 71, and therefore, detailed description thereof is omitted, but the engaging pin is engaged with the engaging hole 68a of the support frame 68 of the recovery roller unit 66 by rotating the handle. Further, similarly to the above, the stopper 87 is also engaged with the engaging hole 87a of the holding plate 70, thereby suppressing the rotation of the support frame 68. The recovery roller shaft portion protruding from the support frame 68 is retracted to the opening 70b, and does not interfere with the holding plate 70.
The recovery roller unit 66 can be attached to or detached from the holding plate 70 by turning the handle of the engaging member 72 to the left or right.
The above is the configuration of the adhesive sheet sticking apparatus according to the second embodiment of the present invention, and next, the operation of replacing the holding sheet of the adhesive sheet sticking apparatus according to the second embodiment will be described below with reference to fig. 7(a) to 11.
Fig. 7(a) shows a state where the adhesive sheet sticking apparatus 6 has run out of the holding sheet 13. The supply roller unit 54 holding the supply roller 55 that becomes empty is disengaged from the first holding mechanism 53, and the peeling roller 52 is removed from the roller frame 73. Further, the recovery roller unit 66 holding the recovery roller 67 around which the used holding sheet 13 is wound is separated from the second holding mechanism 65. Further, by releasing the engagement of the ball plunger (for example, pulling out the ball plunger), the supply roller unit 54 can be easily disengaged from the first holding mechanism 53, and the recovery roller unit 66 can be easily disengaged from the second holding mechanism 65.
Next, a method of forming the replacement unit 74 will be described with reference to fig. 8(a) to 11.
First, as shown in fig. 8(a), the supply roller 55 of the holding sheet 13 is mounted and shaft-supported on the support frame 57 of the supply roller unit 54. At this time, the tip end portion of the holding piece 13 is inserted into the opening of the support frame 57 and is supported by the support frame 57 in a state where the tip end is slightly pulled out. As shown in fig. 8(b), the recovery roller 67 of the holding sheet 13 is mounted on and axially supported by the recovery roller unit 66.
As shown in fig. 9 (which is drawn in a vertically reversed manner for convenience of explanation), two holding plates 70 are disposed to face each other with a gap therebetween, and the supply roller unit 54 and the recovery roller unit 66 are disposed at both longitudinal ends of the two holding plates 70 between the two holding plates 70.
Next, the supply roller unit 54 and the recovery roller unit 66 are engaged with the one-side holding plate 70 in the arrow direction. At this time, the stopper 86 provided to the supply roller unit 54 is fitted into the engagement hole 86a of the holding plate 70. Further, the shaft protruding portion of the supply roller 55 is fitted into the escape hole 70c to prevent interference. The engaging member 71 of the holding plate 70 is fitted into the engaging hole 57a of the support frame 57. The stopper 87 of the recovery roller unit 66 is fitted into the engagement hole 87a of the holding plate 70, similarly to the supply roller unit 54. The engaging member 72 of the holding plate 70 is fitted into the engaging hole 68a of the support frame 68.
As shown in fig. 10 (which is depicted as being inverted vertically for convenience), first, the handles of the engaging members 71 and 72 provided on the holding plates 70 are turned, whereby the two holding plates 70 are fixed to the supply roller unit 54 and the recovery roller unit 66. Next, the holding sheet 13 is pulled out from the supply roller 55, and the tip end of the holding sheet 13 is connected to the recovery roller 67 by an appropriate method, thereby forming the replacement unit 74.
As shown in fig. 7(b) and 11, the replacing unit 74 is disposed so that the upper surface faces the adhesive sheet sticking apparatus 6. Next, the replacement unit 74 is raised, and thereby the ball plunger of the first holding mechanism 53 is engaged with the engagement hole 57b of the supply roller unit 54. The ball plunger of the second holding mechanism 65 engages with the engaging hole 68b of the recovery roller unit 66.
Fig. 7(c) shows a state where the replacing unit 74 is attached to the adhesive sheet sticking apparatus 6.
Next, as shown in fig. 7(d), the two holding plates 70 of the replacement unit 74 are removed. The two holding plates 70 are removed by rotating the respective handles of the engaging members 71 and 72 in the direction opposite to the mounting direction. By rotating the handle in the reverse direction, the engagement pins of the engagement members 71 and 72 are released, and the two holding plates 70 can be easily removed. After the two holding plates 70 are removed, the peeling roller 52 is attached to the roller frame 73, and thereby the replacement of the supply roller 55 and the recovery roller 67 is completed.
The above is the configuration of the second embodiment of the present invention, but the present invention is not limited to the above configuration and can be modified as appropriate.
As another embodiment, the supply roller unit 54 and the recovery roller unit 66 may be directly attached to the first holding mechanism 53 and the second holding mechanism 65, respectively, without using the holding plate 70 of the second embodiment. In this case, the supply roller unit 54 and the recovery roller unit 66 in fig. 7(a) are removed and the peeling roller 52 is removed, similarly to the second embodiment.
Then, the supply roller unit 54 that supports the new supply roller 55 by a shaft is attached to the first holding mechanism 53, and the recovery roller unit 66 that supports the empty recovery roller 67 by a shaft is attached to the second holding mechanism 65. Then, the holding sheet 13 may be led from the supply roller 55 to the recovery roller 67, and the peeling roller 52 may be attached. Before being mounted on the adhesive sheet sticking apparatus 6, the holding sheet may be wound around the supply roller 55 to the recovery roller 67, and the supply roller unit 54 and the recovery roller unit 66 may be mounted on the first holding mechanism 53 and the second holding mechanism 65.
The present invention has been described in terms of the process of attaching the polarizing plate to the liquid crystal panel, but can be applied to the case of attaching an adhesive sheet to various substrates or plate-like members. The substrate may be not only rectangular but may also be formed in various shapes such as a polygon, a circle, and an ellipse.
Various resins, rubbers, and the like can be used for the holding sheet, and various holding sheets can be used as long as they have flexibility, can hold the adhesive sheet with an appropriate holding force, and can be detached from the adhesive sheet. The adhesive sheet can be held by the holding sheet by various holding forces such as adhesive force and adsorption force due to porosity. The replacement unit is not limited to the disclosed shape or mechanism, and various replacement units can be used as long as the supply roller or the recovery roller can be detachably held.
