Although the structure which specifically consists of a conveyance roller as liquid crystal panel conveyance means is illustrated by patent document 1, there is also a mention about the structure which has a suction plate etc. FIG.

Japanese Patent No. 5911035 (Patent Document 2) discloses a method of bonding an optical film to a relatively small size optical display panel such as a smartphone or a small tablet. According to the method described in Patent Document 2, a plurality of optical display cells are arranged vertically and horizontally on a base material to form a cell aggregate mother board, and an optical film sheet is used as an optical display cell on the cell aggregate mother board. After lamination, the optical film sheet is cut to a size corresponding to the individual optical cells.

A conventional RTP system is applied to the application of a film to a relatively rigid panel such as a liquid crystal display panel having a glass substrate on both sides as described in Patent Document 1 It is. However, there is another field of film application where the technology of the RTP system can be applied, and the application can take advantage of the RTP system such as improvement of production efficiency. For example, there exists an application which affixes a resin film like a polarizing film on the fixed form panel which consists of quarter retardation film cut out by predetermined shape and a predetermined dimension. In this case, the 1⁄4 retardation film may be bonded to the polarizing film as a laminate with the 1⁄2 retardation film. Moreover, the film laminated body which bonded together the brightness improvement film to the polarizing film is also used universally, and in manufacture of such a film laminated body, one side of a polarizing film and a brightness improvement film is made into a predetermined shape and a predetermined dimension. It is considered to be advantageous from the viewpoint of improvement in productivity if it is possible to form a formed shaped panel and to attach the other of the polarizing film and the brightness enhancement film to this shaped panel by the RTP system.

Furthermore, in the manufacture of organic EL display devices, which has been remarkably spread in recent years, an organic EL (Organic LED, commonly known as "OLED") display panel has a thin film transistor (TFT) layer and a light emitting layer of an organic material formed on a glass substrate. The upper surface protective film in the form of a resin film is laminated on the light emitting layer. Next, the glass substrate is peeled off, and a resin film-like lower surface protective film is attached to the TFT layer exposed as a result of the peeling. Also in this case, it is advantageous to apply the RTP system to the process of bonding the lower surface protective film which is a resin film to the laminate of the TFT layer, the light emitting layer and the upper surface protective film from the viewpoint of productivity improvement. is there.

However, in any of the above-described cases, the panel to which the resin film is bonded is flexible, and the structure using the conveyance roller described in Patent Document 1 is flexible without causing problems such as positional deviation. Panels can not be passed between lamination rollers to perform lamination. Patent Document 2 shows a configuration in which a cell assembly mother board is placed on a bonding suction holding plate and passed to a bonding station while holding the cell assembly mother board by a suction force. By adopting the configuration shown in Patent Document 2, it is considered possible to bond a resin film to a flexible panel.

However, in the RTP system disclosed in Patent Document 2, the suction suction holding plate for bonding on which the cell assembly mother board is mounted is moved from the first surface inspection station disposed upstream of the bonding station to the bonding station. Configured to be sent to a second surface inspection station disposed downstream of the laminating station, the laminating suction and holding board on which the assembled cell assembly mother board is placed. There is. For this reason, the bonding suction holder must move along a long transport path, and a complicated and expensive suction for applying suction to the bonding suction holder across the entire long transport path. It will be necessary to provide a mechanism. Further, in the RTP system described in Patent Document 2, since the distance of the conveyance path to which the suction and holding board for lamination is moved is long, another conveyance in which the cell aggregate mother board after lamination is disposed on the downstream side It is not possible to return the suction suction holding board for bonding that has been emptied by reprinting on the disc to the upstream side by the same route, and it becomes necessary to provide a return path for an empty suction holding board separately. It requires a large installation space.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view schematically showing the entirety of a resin film bonding system according to an embodiment of the present invention for bonding a resin film to a fixed panel. Although this embodiment is a specific example in the case of using an optical film as a resin film, the resin film in the present invention is not limited to the optical film provided with optical characteristics, and is formed of other resin materials. Film can also be included.

The resin film bonding system 1 shown in FIG. 1 uses a roll 10 of a long strip-like resin film laminate 11. In the present embodiment, as shown in FIG. 2, the resin film laminate 11 comprises a long strip-like carrier film 11 a and an optical film 11 c laminated on the carrier film 11 a via the pressure-sensitive adhesive layer 11 b. . The carrier film 11a can be formed of, for example, a resin material such as PET. The width direction dimension of the resin film laminate 11 is a predetermined dimension corresponding to the width direction dimension or the length direction dimension of the fixed panel to which the sheet of the optical film 11c is attached as will be described later by the resin film attachment system of this embodiment. is there.

As the optical film 11c, typically, a polarizing film can be mentioned, but for example, a resin film having other optical properties such as a 1⁄4 wavelength or 1⁄2 wavelength retardation film or a brightness enhancement film It can also be done. When a polarizing film is used as the optical film 11 c, it is preferable that the absorption axis of the polarizing film be oriented in the longitudinal direction of the resin film laminate 11. The adhesive force of the pressure-sensitive adhesive layer 11b is adjusted so that the adhesive force to the carrier film 11a is smaller than the adhesive force to the optical film. As described above, the resin film in the present invention includes a film made of a resin material other than an optical film, and as an example of a resin film other than such an optical film, a protective film to be bonded to a polarizing film or other films And a protective film usually referred to as a lower surface protective film, which is bonded to the TFT layer of the organic EL display panel.

The resin film bonding system 1 includes a roll support unit 20 and a bonding station 30. The roll 10 of the resin film laminate 11 is rotatably supported by a support shaft 21 provided on the roll support unit 20. The bonding station 30 is provided with a fixed panel feed mechanism 40 for feeding a rectangular shaped fixed panel 31 having a long side dimension and a short side dimension to the bonding unit 32. In the affixing station 30, an affixing roller mechanism 34 having an affixing roller 33 is provided in the affixing unit 32, and a wedge-shaped peeling member 35 is disposed at a position close to the affixing roller mechanism 34.

The resin film laminate 11 fed from the roll 10 rotatably supported by the support shaft 21 passes through the incision forming portion 22 and passes through the dancer roller mechanism 23 to the position where the peeling member 35 is disposed by the guide rolls 24 and 25. Led to

The incision forming portion 22 includes an incision blade 22 a and a pedestal 22 b disposed so as to face the incision blade 22 a with the resin film laminated body 11 drawn from the roll 10 interposed therebetween. The incision forming portion 22 is configured to form, in the width direction of the resin film laminate 11, an incision 11e having a depth that extends from the side of the optical film 11c to the interface between the adhesive layer 11b and the carrier film 11a. It is done. The formation of the incision 11e is performed by stopping the feeding of the resin film laminate 11 in the incision forming portion 22. That is, the feeding of the resin film laminate 11 is intermittently stopped in the incision forming portion 22 and the incision is performed in the stopped state, and as a result, the resin film laminate 11 has a plurality of incisions 11 e. Are formed at predetermined intervals in the longitudinal direction. When the resin film laminate 11 has a predetermined width corresponding to the short side dimension of the fixed panel 31, the predetermined interval of the cuts 11 e in the width direction formed in the resin film laminate 11 is a length of the fixed panel 31. It shall correspond to the side dimensions. As a result of this incision 11e, as shown in FIG. 2, in the resin film laminate 11, a rectangular adhesive comprising an optical film 11c and an adhesive layer 11b between two incisions 11e adjacent in the longitudinal direction. The agent layer-attached sheet 11d is formed.

As shown in FIGS. 1 and 2, the resin film laminate 11 guided to the position of the peeling member 35 is folded back at an acute angle at the leading end edge of the peeling member 35. At this time, the film sheet 11d with a pressure-sensitive adhesive layer formed in a rectangular shape and including the optical film 11c and the pressure-sensitive adhesive layer 11b formed on the resin film laminate 11 is peeled off from the carrier film 11a. Led to the side. The carrier film 11 a from which the pressure-sensitive adhesive layer-attached film sheet 11 d is peeled off is guided by the guide roll 26 and wound up by the winding drive shaft 27. The winding drive shaft 27 is driven at a predetermined speed, and the feed of the resin film laminate 11 is determined by the winding speed. On the other hand, since the resin film laminated body 11 is intermittently stopped in the incision forming part 22, a feed speed difference is generated. A dancer roller mechanism 23 is provided to compensate for this feed speed difference.

As shown in FIGS. 1 and 2, the fixed panel feeding mechanism 40 includes a suction holding member 41, and the fixed panel 31 is shown by an arrow A in FIG. 1 in a state of being suction held on the upper surface of the suction holding member 41. In the direction, it is sent through the sticking part 32. The feed of the fixed panel 31 by the adsorption holding member 41 is synchronized with the feed of the resin film laminate 11, and the fixed end of the adhesive-layer-attached resin film sheet 11d peeled off by the peeling member 35 is sent to the attaching part 32 It is controlled to be aligned with the tip of the panel 31. In the affixing unit 32, the affixing roller mechanism 34 operates, and the affixing roller 33 presses the adhesive-layer-attached resin film sheet 11d against the fixed panel 31 on the suction holding member 41 to perform the affixing.

The fixed panel transfer line 50 is disposed on the upstream side as viewed in the feed movement direction of the suction holding member 41, and the fixed panel 31 is sent to a position close to the fixed panel mounting position 42 by the transfer line 50. The fixed panel 31 sent to a position close to the fixed panel mounting position 42 by the fixed panel transfer line 50 is transferred onto the suction holding member 41 positioned at the fixed panel mounting position 42 above the fixed panel mounting position 42. A shaped panel mounting mechanism 60 is provided for In addition, the attaching station 30 is provided with a resin film sheet attached fixed panel taking out position 43 for taking out the resin film sheet attached shaped panel 31a to which the resin film sheet 11d has been attached, and adjacent to the downstream side of the taking out position 43 Then, the resin film sheet-attached fixed panel delivery line 51 is disposed. Above this delivery line 51, a panel transfer mechanism 70 for transferring the resin film sheet attached fixed panel 31a to the resin film sheet attached fixed panel delivery line 51 from the resin film sheet attached fixed panel take-out position 43 is disposed. Ru.

4 and 5 show details of the fixed panel feed mechanism 40. FIG. FIG. 4 is a side view of the fixed panel feed mechanism 40, and FIG. 5 is an end view seen in the arrow V-V direction of FIG. As shown, the fixed panel feed mechanism 40 has two guide rails 45 disposed on the base 44 in parallel with the direction shown by the arrow A in FIG. The suction holding member 41 is in the form of a rectangular flat plate, and includes four support legs 46 extending vertically downward. The lower end of the support leg 46 is coupled to the lower support plate 47. On the lower surface of the lower support plate 47, a sliding member 48 engaged with the guide rails 45 on the base 44 and slidably moved along the guide rails 45 is fixed. A total of four sliding members 48 are provided, two for each of the pair of guide rails 45.

The fixed panel feed mechanism 40 includes a suction holding member drive mechanism 80. The suction holding member drive mechanism 80 includes a drive screw 81 disposed between the pair of guide rails 45 and extending parallel to the guide rails 45. The drive screw 81 is supported on a base 44 so as to be rotatable about its longitudinal axis. On the lower support plate 47, a nut member 82 screwed to the drive screw 81 is fixed. The nut member 82 and the drive screw 81 form a ball-screw mechanism which is in low friction engagement with each other through a number of balls disposed in the nut member 82. The end of the drive screw 81 is coupled to a servomotor 84 via a reduction gear 83 and reversibly driven to rotate by the servomotor 84. As a result of this reversible rotational driving, the suction holding member 41 is driven in the feed direction shown by the arrow A and in the opposite return direction. That is, as a result of the drive screw 81 of the suction holding member drive mechanism 80 being reversibly rotated in the normal direction and reverse direction, the suction holding member 41 moves the bonding station 30 from the fixed panel mounting position 42 which is the forward end. The forward path to the resin film sheet attached fixed panel taking out position 43 is moved in the direction of arrow A in FIG. Then, the suction holding member 41 is moved along the return path in the return direction opposite to the arrow A, with the resin film sheet shaped fixed panel taking-out position 43 as a folded end. The return path is the same path as the forward path, and the suction holding member 41 is returned through the bonding station 30 to the fixed panel mounting position 42 which is the forward end on the forward path side.

The suction holding member 41 is in the form of a suction plate for holding the fixed panel 31 transferred onto the suction holding member 41 by the fixed panel mounting mechanism 60 by means of the suction force so as not to be displaced. It is preferable that the suction holding member 41 formed of a suction plate be sized so as to cover the entire surface of the fixed-shaped panel 31 to be held by suction. 6A and 6B show an embodiment of the suction holding member 41. FIG. As shown in FIG. 6A, the suction holding member 41 arranges a plurality of rectangular suction plates 41a in a rectangular frame member 41c, and places a partition member 41b between two adjacent suction plates 41a. It is the structure provided. The frame member 41c is integrally formed with the bottom plate 41d, and a suction port 41e is formed on the bottom plate 41d at a position corresponding to each of the plurality of suction plate pieces 41a. Each suction port 41e is connected to a collecting pipe 41h via a branch pipe 41g having a valve 41f, and the collecting pipe 41h is connected to a suction source P such as a vacuum pump.

By providing the branch pipe 41g having the partition member 41b and the valve 41f, it is possible to appropriately control the opening and closing of the valve 41f to select the suction plate 41a on which the suction force acts, thereby forming a large shaped panel corresponding to the dimensions of the frame member 41c. Not only 31 but also fixed shaped panels 31 with medium and small dimensions can be reliably suctioned and held. However, the suction plate 41a can also be configured as a single plate of a size corresponding to the size of the frame member 41c. The suction plate 41a can be formed of a porous material. Examples of porous materials can include porous films of porous ceramics or high molecular weight resins. As an example of porous ceramics that can be used in the present embodiment, there are fine diameter porous ceramics NPP-3D manufactured by Japan Tungsten Co., Ltd. Further, as the porous resin film, there is a high molecular weight polyethylene porous film "Sunmap LC-T" manufactured by Nitto Denko Corporation. In addition, in the present embodiment, a porous plate in which fine through holes are formed on the entire surface can also be used. When a perforated plate is used, the diameter of the through hole is preferably 3 mm or less, and the distance between the holes is preferably 30 mm or less. If the hole diameter is larger than 3 mm, a mark of the hole may remain in the fixed panel 31 held by the suction holding member 41. In addition, if the spacing between the holes is too large, a sufficient suction force can not be obtained and the holding may be uncertain.

Referring to FIG. 4, a branch pipe 41 g and a collecting pipe 41 h are shown below the suction holding member 41. The fixed panel feeding mechanism 40 further includes a hose-incorporated flexible belt 49 for applying a suction negative pressure to the collecting pipe 41 h. The hose built-in flexible belt 49 has a structure in which a hollow hose 49b is embedded in a belt base 49a made of a flexible material such as rubber, and the belt base 49a has one end on the base 44 and the other end. Are fixed to the lower support plate 47 supporting the suction holding member 41, respectively. The collecting pipe 41h communicated with the suction plate 41a via the branch pipe 41g and the suction port 41e is fixed at the end fixed to the lower support plate 47 of the hose built-in flexible belt 49, that is, at the movable end. The hose is connected to the end of a hollow hose 49 b embedded in a flexible belt 49. On the other hand, the end fixed to the base 44 of the hose built-in flexible belt 49, that is, the fixed end is connected to the suction source P by a connection hose 41j. In the fixed panel mounting position 42 shown in FIG. 4, the belt base 49 a of the hose built-in flexible belt 49 is in a state of being folded back at a substantially central position in the length direction.
