Description

Method for producing laminate

The present invention relates to a method for producing a laminate.

There has been disclosed a bonding method in which a display panel such as a liquid crystal display is adsorbed on a curved plate and the curved plate is pressed against the object to be bonded in such a state to thereby adhere the display panel to the object to be bonded (for example, Patent Document 1).

Japanese Laid-Open Patent Publication No. 2016-42120

Fig. 14 is a view for explaining a conventional method of producing a laminated body. In short, Fig. 14 is a view for explaining the conjugation method related to Patent Document 1. When the large display panel 1 is to be adhered to the workpiece 5 in accordance with the bonding method related to Patent Document 1, the display panel 1 is curved on the side of the attraction surface side and the adhesion surface side of the display panel 1 that are attracted to the curved plate 6 There is a possibility that the displacement of the display panel 1 due to the difference in curvature becomes large. In addition, when the large-sized display panel 1 is bonded to the workpiece 5, there is a possibility that workability such as alignment is deteriorated.

The first main surface (for example, the adsorption surface) 2 of the display panel 1 and the second main surface (e.g., the adsorption surface) of the display panel 1 are curved in a bow- In the second main surface (for example, the concave surface) 3 of the panel 1, there is a difference in curvature and a difference in size. This difference may cause (1) breakage of the display panel 1, and (2) deterioration of the visibility of the display image of the display panel 1.

For example, when the display panel 1 is a liquid crystal display panel, if the entire liquid crystal display panel is curved in an arcuate shape, there is a difference in curvature between the TFT (thin film transistor) substrate and the CF There is a difference. As a result, the sealing layer for sealing the liquid crystal between the TFT substrate and the CF substrate may be broken.

The sealing layer adheres the TFT substrate and the CF substrate to the outer periphery of the liquid crystal display panel. The TFT substrate and the CF substrate may not be bonded at the central portion of the liquid crystal display panel. Therefore, when the sealing layer is not broken, the gap (also referred to as a " liquid crystal cell gap ") between the TFT substrate and the CF substrate may be deviated so that the difference between the sizes of the TFT substrate and the CF substrate is absorbed. Specifically, the liquid crystal cell gap at the central portion of the liquid crystal display panel may be larger than the liquid crystal cell gap at the outer peripheral portion of the liquid crystal display panel. The deviation of the liquid crystal cell gap lowers the visibility of the display image.

Further, a stress is generated due to the difference in size between the TFT substrate and the CF substrate, and a substrate (e.g., glass substrate) for forming TFTs and TFTs, a substrate (for example, a glass substrate) for forming CFs and CFs Of course, it can be broken. In addition to the liquid crystal display panel, for example, in an organic EL display panel or a plasma display panel, stress may be generated and breakage may occur.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings. In the drawings, the same constituent parts are denoted by the same reference numerals, and redundant explanations may be omitted.

[First Embodiment]

1 is a side view of a laminate manufacturing apparatus 100 according to the first embodiment. 2 is a top view of the apparatus 100 for producing a laminate according to the first embodiment. 3 is a sectional view taken along line A-A in Fig.

1 to 3, the manufacturing apparatus 100 has a support 30, an attracting plate 40, a laminator 50, a slide pick-up 60, and a fixed pick-up 70.

The support 30 is a substantially rectangular plate-like member. As the base 30, for example, a resin material such as polyvinyl chloride, or a metal material such as aluminum can be used. On the base 30, a transparent substrate 10 as a first plate member is placed. An adhesive layer 11 for bonding to the display panel 20 as the second plate member is formed on the surface of the transparent substrate 10 opposite to the base 30. The material of the adhesive layer 11 is not limited as long as the transparent substrate 10 and the display panel 20 can be bonded to each other. The adhesive layer 11 may be formed on the surface of the display panel 20 to be bonded to the transparent substrate 10.

The transparent substrate 10 is, for example, an inorganic glass plate such as soda lime glass, aluminosilicate glass, aluminoborosilicate glass or alkali-free glass, or an organic glass plate such as polycarbonate resin or acrylic resin. The transparent substrate 10 may be a laminated glass in which a plurality of glass plates are bonded.

At one end of the support 30, a positioning member 32 for aligning the position of the suction plate 40 with respect to the support 30 is formed. 1, the positioning member 32 is formed in an L shape as viewed from the side, and one end of the suction plate 40 is in contact with the positioning member 32. As shown in Fig.

The adsorption plate (40) has a first adsorption plate (41) and a second adsorption plate (42). The first adsorption plate 41 and the second adsorption plate 42 are rectangular flat plate members formed of a resin material such as polyvinyl chloride. The adsorption sheet is adhered to both surfaces of the second adsorption plate 42, and one surface is adsorbed to the first adsorption plate 41. The display panel 20 is attracted to the other surface of the second adsorption plate 42.

The display panel 20 is, for example, a liquid crystal display panel, and has a deflecting plate, an orientation layer, a pair of glass plates functioning as electrodes, liquid crystal sealed between a pair of glass plates, and the like. The display panel 20 may be, for example, an organic EL display panel, a plasma display panel, or the like. In addition, the second plate-shaped member to be bonded to the transparent substrate 10 as the first plate member is not limited to the display panel.

An abutment member 43 is formed at one end of the first adsorption plate 41 so as to abut the positioning member 32 of the receiver 30. The suction plate 40 is fixed in a state in which the abutment member 43 is abutted against the positioning member 32 of the support 30 to thereby determine the position with respect to the support 30. The adsorption plate 40 is positioned as described above and is arranged to face the receiver 30 so that the display panel 20 is on the transparent substrate 10 side.

A support plate 31 is formed between the end of the second adsorption plate 42 on the positioning member 32 side and the transparent substrate 10. The auxiliary base plate 31 is a plate-like member having the same thickness as the total thickness of the display panel 20 and the adhesive layer 11 so that when the end portion of the display panel 20 is bonded to the transparent substrate 10 when bonding in the laminator 50, So that it is prevented from being damaged. It is preferable to form a backing plate 33 between the other end of the second adsorption plate 42 and the transparent substrate 10. The backing plate 33 is the same member as the base plate 31. It is possible to prevent the end portion of the display panel 20 from being pressed and damaged by the pressing roller 51 when the display panel 20 passes through the laminator 50 by forming the backing plate 33. [ The auxiliary base plate 31 and the rear main plate 33 may be fixed to either the transparent substrate 10 or the second adsorption plate 42. [

The second adsorption plate (42) is smaller in length and width than the first adsorption plate (41). Therefore, even in a state in which the adsorption plate 40 is pressed toward the receiver 30 and the display panel 20 is bonded to the transparent substrate 10, between the first adsorption plate 41 and the transparent substrate 10, A space is formed outside the second adsorption plate 42. The transparent substrate 10 and the display panel 20 can be bonded to each other without containing the printed substrate formed on the display panel 20 and damaging the printed substrate. In addition, even if the printed circuit board is taken out of the suction plate 40, damage can be prevented.

The laminator 50 has a pressure roller 51 and a driving roller 52. [ The laminator 50 presses the adsorption plate 40 toward the support 30 between the pressurizing roller 51 and the drive roller 52 to press the transparent substrate 10 and the display panel 20 against the adhesive layer 11, Respectively.

The pressure roller 51 is elastically supported toward the driving roller 52 so as to press the suction plate 40 toward the support 30. The drive roller 52 carries the support 30 and the suction plate 40 which are rotationally driven and inserted between the pressure roller 51 and the suction roller 40 in the direction of arrow A1 shown in Fig. The pressure roller 51 is rotatably formed and is driven by the support 30 and the suction plate 40 conveyed to the drive roller 52 by the frictional force between the pressure roller 51 and the first suction plate 41, do.

The laminator 50 may move relative to the receiver 30 and the suction plate 40 as long as the laminator 50 and the receiver 30 and the suction plate 40 are movable relative to each other. If the display panel 20 can be pressed onto the transparent substrate 10 via the suction plate 40 while the relative movement is performed with respect to the pedestal 30 and the suction plate 40, May be configured differently.

The slide pick-up 60 is fixed at a position which is a predetermined distance from the laminator 50 toward the advancing direction (the direction opposite to the arrow A1 direction), and the transparent substrate 10 and the display panel 20 The adsorption plate 40 is held at a predetermined interval.

The slide pickup 60 has a slide plate 61 and a slide pad 62. The slide plate 61 is formed by holding a plurality of slide pads 62 and fixed at a predetermined distance from the laminator 50 toward the advancing direction of the lap 50 and a predetermined height from the pedestal 30 . The slide plate 61 is fixed to the casing of the laminator 50, for example. The slide pad 62 adsorbs and holds the adsorption plate 40 by, for example, vacuum adsorption. The slide pad 62 holds the adsorption plate 40 while sliding on the surface of the adsorption plate 40 which is coated with fluorine on the adsorption surface and is conveyed by the laminator 50, for example.

If the slide pick-up 60 can be held in the width direction (the direction orthogonal to the conveying direction of the laminator 50) by holding the suction plate 40 from the side not in contact with the display panel 20, The present invention is not limited to the configuration exemplified in the embodiment.

The fixed pick-up 70 holds the attracting plate 40 so that a predetermined gap is formed between the transparent substrate 10 and the display panel 20 and is held together with the attracting plate 40 conveyed by the laminator 50 Move.

The fixed pick-up 70 has a holding plate 71, a suction pad 72, and a leg 73. The holding plate 71 holds a plurality of adsorption pads 72. The adsorption pad 72 adsorbs and holds the adsorption plate 40 by, for example, vacuum adsorption. The legs 73 are formed at both ends of the holding plate 71. One end of the leg 73 is fixed to the holding plate 71, and the other end is abutted against the support 30. The fixed pick-up 70 holds the attracting plate 40 by the attracting pad 72 and the attracting plate 40 which is carried by the laminator 50 so that the legs 73 come into contact with the receiver 30 Move together. The fixed pick-up 70 moves together with the attracting plate 40 as described above and is detached from the attracting plate 40 in the vicinity of the slide pick-up 60. The fixed pick-up 70 is not limited to the configuration exemplified in the present embodiment as long as it can be held from the side not in contact with the display panel 20 of the attracting plate 40 and can be held in the width direction.

The slide pick-up 60 and the fixed pick-up 70 are configured such that the transparent substrate 10 and the display panel 20 are spaced apart from each other by a predetermined distance or more from the laminator 50 toward the advancing direction of the co- The adsorption plate 40 is held to form the adsorbing plate 40. The number of the slide pick-up 60 and the arrangement of the fixed pick-up 70 or the like is set such that the suction plate 40 is parallel to the transparent substrate 10 and the support 30, It is preferable that the slide pick-up 60 is formed in the vicinity of the center of the advancing direction of the joining of the display panel 20, though it is not limited to the configuration exemplified in this embodiment. As a result, unintended deformation of the display panel 20 due to gravity can be suppressed, and unintended contact between the display panel 20 and the adhesive layer 11 can be suppressed.

As described above, when the suction plate 40 held by the slide pick-up 60 and the fixed pick-up 70 is inserted into the laminator 50 together with the receiver 30, the suction plate 40 is deformed into an S shape . More specifically, as shown in Fig. 1, the suction plate 40 is disposed between the laminator 50 and the slide pick-up 60 at two points of the curved portion a and the curved portion b together with the display panel 20 Curved.

The front end portion 20c of the display panel 20 and the rear end portion 20d of the display panel 20 are parallel or oblique (parallel in Fig. 1). Here, " forward " means forward of the proceeding direction of the concatenation, and " backward " means forward of the proceeding direction of the concatenation. A first curve portion 20a and a second curve portion 20b are formed between the front end portion 20c and the rear end portion 20d. The first bend section 20a and the second bend section 20b are formed in a mating area described later. The first bend section 20a and the second bend section 20b are curved in opposite directions to each other. In other words, the center of curvature of the first bend section 20a and the center of curvature of the second bend section 20b are formed on the opposite sides with the display panel 20 therebetween.

In this specification, a flat front end portion 20c, a flat rear end portion 20d, and a first curved portion 20a and a second curved portion 20b curved in opposite directions between the front end portion 20c and the rear end portion 20d, 20b are referred to as S shapes. The magnitude of the curvature of the first bend section 20a and the magnitude of the bend of the second bend section 20b are not particularly limited, but are preferably the same.

The first main surface (for example, the adsorption surface) of the display panel 20 is deformed in the S-shaped manner, unlike the case where the entire display panel 20 is curved like an arrow, And the size of the second main surface (for example, the concave surface) of the display panel 20 can be reduced. As a result, at least one of (1) breakage of the display panel 20 and (2) deterioration of the visibility of the display image of the display panel 20 can be suppressed.

For example, when the display panel 20 is a liquid crystal display panel, a difference in size between the TFT substrate and the CF substrate can be suppressed. As a result, breakage of the sealing layer for sealing liquid crystal between the TFT substrate and the CF substrate can be suppressed. In addition, when the sealing layer is not broken, deviation of the liquid crystal cell gap between the TFT substrate and the CF substrate can be suppressed, and deterioration of the visibility of the display image can be suppressed.

It is also possible to suppress breakage of the sealing layer as well as damage to the substrate on which the TFT, the TFT (for example, the glass substrate), CF and CF are formed (for example, the glass substrate). It is also possible to suppress breakage of a display panel other than the liquid crystal display panel (for example, an organic EL display panel or a plasma display panel).

It is preferable that the radius of curvature of the curved display panel 20 and the curved portion of the suction plate 40 in the curved portion a and the curved portion b is set as large as possible so that the display panel 20 is not damaged. For example, when the interval between the laminator 50 and the slide pick-up 60 is 250 mm and the interval between the display panel 20 and the transparent substrate 10 at the position of the slide pick-up 60 is 3 mm, a and the curved portion b can be set to about 5200 mm.

As described above, according to the manufacturing apparatus 100 of the first embodiment, bending of the display panel 20 adsorbed and held by the attracting plate 40 is suppressed, and the display panel 20 is prevented from being damaged, (10). ≪ / RTI >

Next, a method of manufacturing the laminate according to the first embodiment will be described. Fig. 4 is a view for explaining a method of manufacturing a laminate according to the first embodiment. Fig. 4 (A) is a view showing a state at the time when the display panel and the transparent substrate are started to be connected. Fig. 4B is a view showing a state in which the display panel and the transparent substrate are being bonded. 4 (C) is a view showing a state at the time of completion of the bonding of the display panel and the transparent substrate. 4 shows a state in which the transparent substrate 10 and the display panel 20 are laminated in the manufacturing apparatus 100 to produce a laminate.

First, as shown in Fig. 4 (A), a receiver 30 on which a transparent substrate 10 is placed and an adsorption plate 40 for adsorbing and holding the display panel 20 are arranged to face each other. The attracting plate 40 is supported by the slide pick-up 60 and the fixed pick-up 70 so as to form a predetermined gap between the transparent substrate 10 and the display panel 20. The receiver 30 and the suction plate 40 disposed opposite to each other are inserted between the pressure roller 51 and the drive roller 52 of the laminator 50 and are moved in the direction of the arrow A1 in Fig. Lt; / RTI > In the laminator 50, the suction plate 40 is pressed toward the support 30 by the pressure roller 51. [ The adsorption plate 40 is deformed into an S shape.

Next, as shown in Fig. 4 (B), the driving roller 52 of the laminator 50 is rotated to transport the receiving plate 30 and the attracting plate 40 in the direction of the arrow A1. In the laminator 50, the pressure roller 51 presses the adsorption plate 40 toward the support 30, so that the display panel 20 is bonded to the transparent substrate 10 via the adhesive layer 11. Between the transparent substrate 10 and the display panel 20, a connection wire is formed. The bonding wires are the boundaries between the bonding region where the transparent substrate 10 and the display panel 20 are bonded to each other via the adhesive layer 11 and the non-bonding region which is not yet bonded. When the drive roller 52 rotates to convey the receiver 30 and the suction plate 40, the connection wires are advanced in the direction opposite to the direction of the arrow A1 so that the transparent substrate 10 and the display panel 20 are connected to one end side To the other end side.

When the drive roller 52 rotates to transport the receiver 30 and the suction plate 40, the slide pick-up 60 fixedly formed is supported by the receiver 30 and the suction plate 40 together with the laminator 50. [ Lt; / RTI > The fixed pick-up 70 for supporting the attracting plate 40 is carried along with the receiver 30 and the attracting plate 40 and is sequentially detached from the vicinity of the slide pick-up 60.

The slide pick-up 60 and the fixed pick-up 70 form a predetermined gap between the transparent substrate 10 and the display panel 20 at a predetermined distance or more from the fused wire toward the advancing direction of the co- And the attracting plate 40 is supported so that the transparent substrate 10 and the display panel 20 are parallel to each other.

Subsequently, as shown in Fig. 4 (C), when the driving roller 52 rotates to convey the receiving plate 30 and the attracting plate 40, the pressing roller 51 presses the display panel 20 on the transparent substrate 10 so that the display panel 20 is bonded to the transparent substrate 10 with the adhesive layer 11 interposed therebetween. When the entire surface of the display panel 20 is bonded to the transparent substrate 10 by the nip wire reaching the end of the display panel 20 and the display panel 20 is stacked on the transparent substrate via the adhesive layer 11 A laminate is obtained. After the entire support 30 and the suction plate 40 have passed between the pressure roller 51 and the drive roller 52 and the suction plate 40 is detached from the display panel 20, And the display panel 20 can be obtained.

As described above, according to the first embodiment, the display panel 20 can be bonded to the transparent substrate 10 without significantly curving. The support 30 on which the transparent substrate 10 is placed and the attracting plate 40 on which the display panel 20 is attracted are disposed to face each other so that the gap between the pressing roller 51 of the laminator 50 and the driving roller 52 The display panel 20 can be easily attached to the transparent substrate 10 by passing. As described above, according to the first embodiment, it is possible to manufacture a laminate in which the display panel 20 is laminated on the transparent substrate 10 by being easily bonded to the transparent substrate 10 without damaging the display panel 20 have.

[Second Embodiment]

Next, a second embodiment will be described with reference to the drawings. The description of the same components as those of the previously described embodiment is omitted.

5 is a side view of the apparatus 200 for producing a laminate according to the second embodiment. 6 is a top view of the apparatus 200 for producing a laminate according to the second embodiment. 7 is a sectional view taken along the line B-B in Fig.

5 to 7, the manufacturing apparatus 200 has a support 30, an attracting plate 40, a laminator 50, a support balloon 80, and a fixed pick-up 90. On the base 30, a transparent substrate 10 is placed. Further, the display panel 20 is adsorbed on the adsorption plate 40.

The supporting balloon 80 is formed between the transparent substrate 10 and the first adsorption plate 41 and is provided with a suction plate 40 so as to form a predetermined gap between the transparent substrate 10 and the display panel 20 . The supporting balloon 80 is formed of a resin material such as stretchable rubber having a thickness of 1 mm, for example, in the form of a bag, and air is injected into the balloon 80 at a predetermined pressure. 6 and 7, the support balloon 80 is formed at both end portions in the width direction perpendicular to the conveying direction of the support 30 and the attraction plate 40 by the laminator 50 have.

The supporting balloon 80 is compressed between the pressing roller 51 and the driving roller 52 in the laminator 50. The supporting balloon 80 is contracted to a thickness that is not affected by the pressing of the pressing roller 51 in the laminator 50 to adhere the display panel 20 to the transparent substrate 10, The adhesion between the transparent substrate 10 and the display panel 20 can be maintained even after passing through the transparent substrate 10. The supporting balloon 80 is transparent at a predetermined distance or more from the conjugate wire toward the advancing direction of the cohesion (opposite to the direction of arrow A2) in the sub-area of the transparent substrate 10 and the display panel 20 The first adsorption plate 41 is supported so as to form a predetermined gap between the substrate 10 and the display panel 20.

The display panel 20 adsorbed to the adsorption plate 40 and the adsorption plate 40 is deformed into an S shape as shown in Fig. 5 by being supported by the support balloon 80 as described above. In addition, the attracting plate 40 is supported so that the transparent substrate 10 and the display panel 20 are parallel to each other at a predetermined interval at a predetermined distance or more from the conjugate wire toward the proceeding direction in the non-overlap region.

The fixed pick-up 90 has a holding plate 91 and a suction pad 92. The holding plate 91 holds a plurality of adsorption pads 92. The adsorption pad 92 adsorbs and holds the adsorption plate 40 by, for example, vacuum adsorption. Adsorption pads (92) are attached to both ends in the width direction of the adsorption plate (40) and at the center in the width direction. 7, the fixed pickup 90 is supported by the supporting balloon 80 via the adsorption plate 40 at both end portions in the width direction, and the adsorption pad 92 at the center in the widthwise direction is supported by the supporting balloon 80, Thereby adsorbing and holding the adsorption plate 40. Therefore, the fixed pickup 90 can suppress the sideways center portion of the suction plate 40 from being sagged than both end portions in the width direction, and the contact between the display panel 20 and the adhesive layer 11 on the transparent substrate 10 . The fixed pickup 90 moves together with the suction plate 40 carried by the laminator 50 and is detached from the suction plate 40 at a predetermined position close to the laminator 50. [

The fixed pickup 90 is also capable of holding the attracting plate 40 to prevent the display panel 20 and the transparent substrate 10 from coming into contact with each other by bending the attracting plate 40 in the width direction, The present invention is not limited to the configuration exemplified in this embodiment. The compression member that is supported by the suction plate 40 and is compressed by the laminator 50 may be, for example, a sponge formed of a resin material.

As described above, according to the manufacturing apparatus 200 in the second embodiment, bending of the display panel 20 held by the suction plate 40 is suppressed, (20) without damaging the transparent substrate (10).

The attracting plate 40 is supported by the supporting balloon 80 and the plurality of fixed pickups 90 so as to form a predetermined gap between the transparent substrate 10 and the display panel 20. The pedestal 30 and the suction plate 40 are inserted between the pressure roller 51 and the driving roller 52 of the laminator 50 and conveyed in the direction of arrow A2 in Fig. In the laminator 50, the suction plate 40 is pressed toward the support 30 by the pressure roller 51. [ The adsorption plate 40 is deformed into an S shape.

8 (B), the driving roller 52 of the laminator 50 is rotated to transport the receiver 30 and the suction plate 40 in the direction of arrow A2. In the laminator 50, the pressure roller 51 presses the adsorption plate 40 toward the support 30 so that the support balloon 80 is compressed so that the display panel 20 is sandwiched between the transparent substrate (10). When the drive roller 52 rotates to convey the receiver 30 and the attracting plate 40, the conjugate electric wire is advanced in the direction opposite to the direction of the arrow A2 so that the transparent substrate 10 and the display panel 20 are moved to the one end side To the other end side. The fixed pick-up 90 holding the adsorption plate 40 is transported together with the receiver 30 and the adsorption plate 40 and sequentially detached from the vicinity of the laminator 50.

[Third embodiment]

Next, a third embodiment will be described with reference to the drawings. The description of the same components as those of the previously described embodiment is omitted.

9 is a side view of the apparatus 300 for producing a laminate according to the third embodiment.

9, the manufacturing apparatus 300 has a support 30, an attracting plate 40, a laminator 50, a fixed pick-up 90, and a support block 95. As shown in Fig. On the base 30, a transparent substrate 10 is placed. Further, the display panel 20 is adsorbed on the adsorption plate 40.

The support block 95 is formed between the transparent substrate 10 and the first adsorption plate 41 and is provided with a suction plate 40 so as to form a predetermined gap between the transparent substrate 10 and the display panel 20 . The support block 95 is formed at both end portions in the width direction perpendicular to the conveying direction of the support 30 and the suction plate 40 by the laminator 50. [ The support block 95 is fixed and formed together with the laminator 50 and moves relative to the support 30 and the attracting plate 40 conveyed by the laminator 50. [

The slidable surface of the support plate 95 on the side of the suction plate 40 is an inclined surface inclined with respect to the slid surface on the side of the transparent substrate 10 and is inclined in the S- As shown in Fig. The adsorption plate 40 whose both end portions in the width direction are supported by the inclined surface of the support block 95 is deformed into the S shape along the inclined surface of the support block 95 as shown in Fig. The attracting plate 40 is located at a predetermined distance or more from the conjugate wire toward the proceeding direction of the cohesion (the direction opposite to the direction of the arrow A3) in the subjacent area of the transparent substrate 10 and the display panel 20, The transparent substrate 10 and the display panel 20 are supported so as to be parallel to each other at regular intervals.

The fixed pick-up 90 has a holding plate 91 and a suction pad 92 and sucks and holds the suction plate 40. The fixed pick-up 90 prevents the central portion of the adsorption plate 40 from bending in the width direction. The fixed pickup 90 moves together with the suction plate 40 carried by the laminator 50 and is detached from the suction plate 40 at a predetermined position close to the laminator 50. [

The manufacturing apparatus 300 according to the third embodiment suppresses the bending of the display panel 20 held by the suction plate 40 so that the display panel 20 Can be bonded to the transparent substrate 10 without damaging the transparent substrate 10.

Next, a method of manufacturing the laminate according to the third embodiment will be described. 10 is a view for explaining a method of manufacturing a laminate according to the third embodiment. 10 (A) is a view showing the state at the time when the display panel and the transparent substrate are started to be bonded. 10B is a diagram showing a state during the fusion of the display panel and the transparent substrate. 10 (C) is a view showing the state at the time of ending the bonding of the display panel and the transparent substrate. 10 shows a state in which the transparent substrate 10 and the display panel 20 are laminated in the manufacturing apparatus 300 to produce a laminated body.

First, as shown in Fig. 10 (A), a support 30 having a transparent substrate 10 is sandwiched by a support block 95, and an adsorption plate 40 for adsorbing and holding the display panel 20, . The attracting plate 40 is supported by the support block 95 and the plurality of fixed pickups 90 to form a predetermined gap between the transparent substrate 10 and the display panel 20. [ The support 30 and the suction plate 40 are inserted between the pressure roller 51 and the drive roller 52 of the laminator 50 and conveyed in the direction of arrow A3 in Fig. In the laminator 50, the suction plate 40 is pressed toward the support 30 by the pressure roller 51. [ The adsorption plate 40 is deformed into an S shape.

Next, as shown in Fig. 10 (B), the driving roller 52 of the laminator 50 is rotated to transport the receiver 30 and the attracting plate 40 in the direction of arrow A3. In the laminator 50, the pressure roller 51 presses the adsorption plate 40 toward the support 30, so that the display panel 20 is bonded to the transparent substrate 10 via the adhesive layer 11. When the drive roller 52 rotates to convey the receiver 30 and the attracting plate 40, the conjugate electric wire is advanced in the direction opposite to the direction of the arrow A3 so that the transparent substrate 10 and the display panel 20 are connected to one end side To the other end side. The support block 95 supporting the adsorption plate 40 is fixed together with the laminator 50 and moves relative to the receiver 30 and the adsorption plate 40. The fixed pick-up 90 holding the adsorption plate 40 moves together with the receiver 30 and the adsorption plate 40 and is sequentially detached from the vicinity of the laminator 50. [

The transparent substrate 10 and the display panel 20 form a predetermined gap between the support block 95 and the fixed pickup 90 at a predetermined distance or more from the fused wire in the overlapped area, 10 and the display panel 20 are parallel to each other.

10 (C), when the driving roller 52 rotates to convey the receiving plate 30 and the attracting plate 40, the pressing roller 51 presses the display panel 20 against the transparent substrate 10 so that the display panel 20 is bonded to the transparent substrate 10 with the adhesive layer 11 interposed therebetween. When the entire surface of the display panel 20 is bonded to the transparent substrate 10 by the nip wire reaching the end of the display panel 20 and the display panel 20 is stacked on the transparent substrate via the adhesive layer 11 A laminate is obtained. After the entire support 30 and the suction plate 40 have passed between the pressure roller 51 and the drive roller 52 and the suction plate 40 is detached from the display panel 20, And the display panel 20 can be obtained.

As described above, according to the third embodiment, the display panel 20 is easily bonded to the transparent substrate 10 without breakage, and the laminated body in which the display panel 20 is laminated on the transparent substrate 10 Can be manufactured.

[Fourth Embodiment]

Next, a fourth embodiment will be described with reference to the drawings. The description of the same components as those of the previously described embodiment is omitted.

11 is a side view of the apparatus 400 for producing a laminate according to the fourth embodiment.

11, the manufacturing apparatus 400 has a support 30, an attracting plate 40, a laminator 50, a fixed pick-up 90, and a support member 98. As shown in Fig. In the manufacturing apparatus 400 according to the fourth embodiment, the receiver 30 and the suction plate 40 are inserted into the laminator 50 in a state in which they are suspended from the positioning member 32 side. In the base 30, for example, a suction sheet is formed on the surface of the suction plate 40, and the transparent substrate 10 is absorbed. Further, the display panel 20 is adsorbed on the adsorption plate 40.

The support member 98 is formed between the transparent substrate 10 and the first attracting plate 41 and forms a predetermined gap between the transparent substrate 10 and the display panel 20. The support member 98 is formed at both end portions in the width direction of the support 30 and the suction plate 40, respectively. The support member 98 is fixed with the laminator 50 and moves relative to the support 30 and the attracting plate 40 conveyed by the laminator 50. [ The support member 98 may be formed in a roller shape, for example.

The adsorption plate 40 is deformed into an S shape. Below the support member 98, the support 30 and the suction plate 40 are parallel to each other by gravity, and the gap between the transparent substrate 10 and the display panel 20 is maintained constant. By thus resembling the support 30 and the suction plate 40, the center of the suction plate 40 in the width direction is curved due to the gravity at the lower side of the support member 98, And the interval between the transparent substrate 10 and the display panel 20 is kept constant. Therefore, there is no need to form a pick-up or the like for holding the adsorption plate 40, and a simpler configuration can be achieved.

The supporting member 98 is disposed at a predetermined distance from the front end of the transparent substrate 10 and the display panel 20 below the laminator 50 toward the advancing direction of the cohesion The shape or the like is not limited as long as a predetermined gap can be formed between the transparent substrate 10 and the display panel 20. [

The manufacturing apparatus 400 according to the fourth embodiment suppresses bending of the display panel 20 adsorbed and held on the adsorption plate 40 in the same manner as in the first to third embodiments, Can be bonded to the transparent substrate 10 without damaging the transparent substrate 10.

Next, a method of manufacturing the laminate according to the fourth embodiment will be described. Fig. 12 is a view for explaining a method of manufacturing a laminate according to the fourth embodiment. 12 (A) is a view showing a state at the time when the display panel and the transparent substrate are started to be bonded. Fig. 12B is a diagram showing a state in which the display panel and the transparent substrate are being bonded. Fig. Fig. 12C is a view showing a state at the time of ending the bonding of the display panel and the transparent substrate. Fig. 12 shows a state in which the transparent substrate 10 and the display panel 20 are laminated in the manufacturing apparatus 400 to produce a laminated body.

First, as shown in Fig. 12 (A), a support 30 for sandwiching a support member 98 therebetween and for holding and holding the transparent substrate 10, and an adsorption plate 40 are disposed opposite to each other.

A predetermined gap is formed between the transparent substrate 10 and the display panel 20 by the support member 98. [ The pedestal 30 and the suction plate 40 are inserted between the pressure roller 51 and the driving roller 52 of the laminator 50 and conveyed in the direction of the arrow A4 in Fig. In the laminator 50, the suction plate 40 is pressed toward the support 30 by the pressure roller 51. [ The adsorption plate 40 is deformed into an S shape.

Next, as shown in Fig. 12 (B), the driving roller 52 of the laminator 50 is rotated to transport the receiver 30 and the attracting plate 40 in the direction of arrow A4. In the laminator 50, the pressure roller 51 presses the adsorption plate 40 toward the support 30, so that the display panel 20 is bonded to the transparent substrate 10 via the adhesive layer 11. When the drive roller 52 rotates to convey the receiver 30 and the suction plate 40, the connection wires are advanced in the direction opposite to the direction of the arrow A4 so that the transparent substrate 10 and the display panel 20 are connected to one end side To the other end side. The support member 98 is fixed together with the laminator 50 and moves relative to the support 30 and the suction plate 40.

The transparent substrate 10 and the display panel 20 are supported by the supporting member 98 and the gravity at a distance not less than a predetermined distance from the connection wire in the overlapping area between the transparent substrate 10 and the display panel 20, (20).

Subsequently, as shown in Fig. 12 (C), when the driving roller 52 rotates to convey the receiving plate 30 and the attracting plate 40, the pressing roller 51 presses the display panel 20 on the transparent substrate 10 so that the display panel 20 is bonded to the transparent substrate 10 with the adhesive layer 11 interposed therebetween. When the entire surface of the display panel 20 is bonded to the transparent substrate 10 by the nip wire reaching the end of the display panel 20 and the display panel 20 is stacked on the transparent substrate via the adhesive layer 11 A laminate is obtained. After the entire support 30 and the suction plate 40 have passed between the pressure roller 51 and the drive roller 52 and the suction plate 40 is detached from the display panel 20, And the display panel 20 can be obtained.

As described above, according to the fourth embodiment, the display panel 20 is easily attached to the transparent substrate 10 without damaging the display panel 20, A laminated laminate can be produced.

The laminator 50 and the support member 98 are arranged in such a manner that the laminator 50 and the suction plate 40 are moved upward by the laminator 50 and the suction plate 40, Or may be configured to move downward.

[Fifth Embodiment]

Next, a fifth embodiment will be described with reference to Fig. Fig. 13 is a view for explaining a method of manufacturing a laminate according to the fifth embodiment. 13 (A) is a view showing a state at the time of starting the bonding of the display panel and the transparent substrate. Fig. 13B is a view showing a state in which the display panel and the transparent substrate are being bonded. Fig. 13 (C) is a view showing the state at the time of ending the bonding of the display panel and the transparent substrate. The difference between the fifth embodiment and the first to fourth embodiments will be mainly described below.

In the first embodiment, a fixed pick-up 70 is formed at the front end of the attracting plate 40. The fixed pick-up 70 holds the front end of the adsorption plate 40 parallel to the transparent substrate 10 at regular intervals and is detached from the front end of the adsorption plate 40 during the conjugation. The fixed pickup 90 of the second to third embodiments has the same role as the fixed pickup 70 of the first embodiment.

On the other hand, in the fifth embodiment, the movable pickup 75 is formed at the front end of the suction plate 40. The movable pickup 75 holds the front end of the attracting plate 40 parallel to the transparent substrate 10 from the start of the concatenation to the end of the concatenation. The movable pickup 75 gradually approaches the transparent substrate 10 at least immediately before the end of the coupling and gradually reduces the interval between the transparent substrate 10 and the front end of the display panel 20 to zero.

The abutment member 43 shown in Fig. 13 abuts against the transparent substrate 10, instead of abutting against the positioning member 32 of the support 30 shown in Fig. In this case, the base 30 is unnecessary. In the first to fourth embodiments, the abutment member 43 abuts on the transparent substrate 10 instead of abutting against the positioning member 32 of the support 30, similarly to the present embodiment, .

The abutment member 43 is formed at the rear end (upper end in Fig. 13) of the adsorption plate 40 to keep the rear end of the adsorption plate 40 flat. The abutting member 43 is fixed to the transparent substrate 10 to keep the rear end portion of the suction plate 40 parallel to the transparent substrate 10. The same is true in the first to fourth embodiments.

The abutment member 43 may have an adjusting mechanism for adjusting the position of the adsorption plate 40 with respect to the transparent substrate 10 in a state in which the abutment member 43 is fixed to the transparent substrate 10. [ In the first to fourth embodiments, the abutment member 43 is fixed to the transparent substrate 10, and the position of the suction plate 40 relative to the transparent substrate 10 May be provided.

The movable pickup 75 is formed at the front end (lower end in Fig. 13) of the adsorption plate 40 to keep the front end of the adsorption plate 40 flat. The movable pickup 75 approaches the transparent substrate 10 while keeping the front end of the suction plate 40 and the transparent substrate 10 in parallel.

The movable pickup 75 is freely movable along the guide 76. The guide 76 is formed in a bar shape and inserted into the through hole of the movable pickup 75. A plurality of guides 76 may be formed to stabilize the posture of the movable pickup 75.

The movable pickup 75 may be elastically supported in a direction away from the transparent substrate 10 by a spring (not shown). At both ends of the guide 76, a stopper 77 is formed so that the movable pickup 75 is not detached from the guide 76.

13A, the abutment member 43 and the guide 76 are fixed to the transparent substrate 10 at the time of starting the adhesion, and the abutting member 43 and the guide 76 are fixed to the suction plate 40 and the suction plate 40 The adsorbed display panel 20 is deformed into an S shape.

Subsequently, as shown in Fig. 13 (B), while the adsorption plate 40 and the display panel 20 are pressed toward the transparent substrate 10 by the pressure roller 51, the pressure roller 51 is moved forward The display panel 20 and the transparent substrate 10 are moved forward. As a result, the movable pickup 75 gradually approaches the transparent substrate 10 against the elastic force of the spring, and the interval between the transparent substrate 10 and the front end of the display panel 20 gradually narrows.

13 (C), the pressing roller 51 is further moved forward to move the bonding wires further forward so that the distance between the transparent substrate 10 and the front end portion of the display panel 20 becomes By zeroing, the fusion is completed. The adsorption plate 40 is detached from the display panel 20 while the abutment member 43 and the guide 76 are removed from the transparent substrate 10.

Incidentally, in the present embodiment, the transparent substrate 10 is vertically and flatly supported as in the fourth embodiment. For example, when the transparent substrate 10 is a glass window, the transparent substrate 10 is vertically and flatly supported by the window frame. It is possible to suppress unintentional deformation of the display panel 20 that is adhered to the transparent substrate 10 due to gravity by vertically and evenly supporting the transparent substrate 10 and the display panel 20 and the adhesive layer 11 Can be suppressed.

In this specification, the term " vertical " means a slope of 15 DEG or less with respect to the vertical direction.

The support 30 is not formed on the side opposite to the attraction plate 40 with respect to the transparent substrate 10 in the present embodiment. However, the support 30 may be formed similarly to the fourth embodiment. By supporting the transparent substrate 10 by the support 30, deformation of the transparent substrate 10 pressed by the pressure roller 51 can be suppressed. By suppressing the deformation of the transparent substrate 10, the transparent substrate 10 and the display panel 20 can be uniformly bonded.

An auxiliary roller may be formed on the opposite side of the pressing roller 51 with respect to the transparent substrate 10 in order to suppress deformation of the transparent substrate 10 pressed by the pressing roller 51. [ The auxiliary roller and the pressure roller (51) sandwich the transparent substrate (10) to suppress the deformation of the transparent substrate (10). By suppressing the deformation of the transparent substrate 10, the transparent substrate 10 and the display panel 20 can be uniformly bonded.

The auxiliary roller rotates relative to the transparent substrate 10 while relatively moving in the advancing direction of the cohesion. The auxiliary roller may be rotated by relatively moving the auxiliary roller relative to the transparent substrate 10 in the advancing direction of the jig, and the auxiliary roller may be rotated to relatively move the auxiliary roller relative to the transparent substrate 10 in the advancing direction of the jig do. Further, the pressure roller 51 rotates relative to the transparent substrate 10 while moving relatively in the advancing direction of the cohesion, like the auxiliary roller.

The auxiliary roller and the bearing 30 may be used either singly or in combination. When both the auxiliary roller and the support 30 are used, the support 30 may be formed between the auxiliary roller and the transparent substrate 10.

In the present embodiment, by using the movable pickup 75, as the pressing roller 51 moves relative to the transparent substrate 10 in the advancing direction of the stacking, the front end of the display panel 20 and the transparent The interval between the substrates 10 is gradually reduced to zero. Since the interval between the front end of the display panel 20 and the transparent substrate 10 can be gradually reduced immediately before the end of the adhesion, the bonding can be performed smoothly.

The movable pickup 75 may be used together with the support balloon 80 of the second embodiment, the support block 95 of the third embodiment, or the support member 98 of the fourth embodiment .

The visibility of the display panel was confirmed by using the laminate manufactured by the manufacturing method of the first to fifth embodiments and the laminate manufactured by the conventional manufacturing method (the manufacturing method shown in Fig. 14). As a result, in the laminate produced by the conventional manufacturing method, occurrence of display unevenness on the elliptical phase was confirmed. On the other hand, in the layered product produced by the production methods of the first to fifth embodiments, almost no display irregularity was observed, and visibility was good.

Although the method of manufacturing the laminate related to the embodiment has been described above, the present invention is not limited to the above-described embodiments, and various modifications and improvements are possible within the scope of the present invention.

In the first to fifth embodiments, the first plate member is a transparent substrate and the second plate member is a display panel. The present invention is not limited to this embodiment, and the first plate member may be a display panel, the second plate member may be a transparent face member, and the first plate member and the second plate member may be transparent face members.

In the first to fourth embodiments, the transparent substrate 10, the display panel 20, the receiver 30, and the suction plate 40 are moved in a direction opposite to the advancing direction of the cohesion. . For example, in the first to fourth embodiments, the laminator 50 may be moved in the advancing direction of the cohesion.

In the first to fourth embodiments, the drive roller 52 that is rotationally driven by a rotation motor is used, but the present invention is not limited to this. For example, instead of the drive roller 52, a driven roller may be used. The driven roller is freely rotatable and is driven to rotate by the support 30 by the frictional force with the support 30.
