(The problem to be solved by the invention)

The conventional RTP system is described in Patent Document 1, and is suitable for a panel with relatively high rigidity such as a liquid crystal display panel with glass substrates on both sides. However, there is also another field of film bonding that can apply RTP system technology and can utilize the advantages of the RTP system such as increased productivity through this application. For example, there is an application for pasting a resin film like a polarizing film on a shaped panel made of a 1/4 retardation film cut into a predetermined shape and a predetermined size. In this case, the 1/4 retardation film may be bonded to the polarizing film as a laminate with the 1/2 retardation film. In addition, film laminates in which a brightness enhancement film is attached to a polarizing film are also commonly used. In the production of the film laminate as shown above, if one of the polarizing film and the brightness enhancement film can be formed into a predetermined shape And a fixed-shaped panel of a predetermined size, and on this fixed-shaped panel, the other side of the polarizing film and the brightness enhancement film bonded by the RTP system is considered to be advantageous from the viewpoint of productivity improvement.

In addition, in the manufacture of organic EL display devices, which have been extremely popular in recent years, organic EL (Organic LED, commonly referred to as "OLED") display panels are formed on a glass substrate with a thin film transistor (TFT) layer, and organic materials emit light. Layer, a resin film-like top surface protective film is laminated on the light-emitting layer. Next, the glass substrate is peeled off, and a resin film-like underside protective film is bonded to the TFT layer exposed as a result of the peeling. In this case, the RTP system is applied to the process of bonding the underside protective film as a resin film to a laminate composed of the TFT layer, the light-emitting layer, and the upper protective film. It is also from the viewpoint of productivity improvement. favorable.

However, in any of the above cases, the resin film-laminated panel is flexible. In the structure using the transport roller described in Patent Document 1, there will be no problems such as positional deviation, and the flexibility cannot be changed. The sex panel is connected between the bonding rollers for bonding. Patent Document 2 discloses a structure in which a unit assembly mother board is placed on a suction and holding plate for bonding, and the unit assembly mother board is held by suction while leading to a bonding station. If the structure shown in this patent document 2 is adopted, it is considered that bonding to the resin film of a flexible panel can be performed.

However, the RTP system disclosed in Patent Document 2 is composed of a first surface inspection station arranged on the upstream side of the bonding station with a suction and holding plate for bonding on which the unit assembly mother board is placed. It is transported to the bonding station, and the suction and holding tray for bonding on which the unit assembly mother board has been placed is placed, and it is also sent to the second surface inspection, which is arranged on the downstream side of the bonding station. stand. Therefore, the lamination suction and holding disk system must move along the long conveying path, and it is necessary to provide a complicated and expensive suction mechanism for applying attractive force to the lamination suction and holding disk throughout the entire long conveying path. In addition, in the RTP system described in Patent Document 2, since the distance of the conveyance path for moving the lamination suction and holding disk is long, it is impossible to reprint the unit assembly mother board that has been pasted on the back flow side. The suction and holding disk for bonding that has become empty is returned to the upstream side on the same path by other conveying disks, and a return path for the empty suction and holding disk must be provided separately, and a wide setting for the bonding device must be provided space.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a side view schematically showing the entire resin film sticking system of one embodiment of the present invention for sticking a resin film on a shaped panel. The present embodiment is a specific example when an optical film is used as a resin film. However, the resin film in the present invention is not limited to an optical film having optical properties, and may include films formed of other resin materials.

The resin film sticking system 1 shown in FIG. 1 uses the roll 10 of the resin film laminated body 11 of a long strip shape. In this embodiment, the resin film laminate 11 is composed of a long tape-shaped carrier film 11a, and an optical film 11c laminated on the carrier film 11a through an adhesive layer 11b, as shown in FIG. The carrier film 11a can be formed of a resin material such as PET. The width direction size of the resin film laminate 11 is a predetermined size corresponding to the width direction size or the length direction size of the shaped panel on which the sheet of the optical film 11c is pasted by the resin film bonding system of this embodiment as described later.

The optical film 11c typically includes a polarizing film, but it can also be formed as a resin film having other optical properties such as a quarter-wavelength or half-wavelength retardation film or a brightness enhancement film. If a polarizing film is used as the optical film 11c, it is preferable that the absorption axis of the polarizing film is aligned with the longitudinal direction of the resin film laminate 11. The adhesive layer 11b adjusts the adhesive force in such a way that the adhesive force to the carrier film 11a is lower than the adhesive force to the optical film. As described above, the resin film in the present invention includes films made of resin materials other than optical films, but as an example of resin films other than optical films as shown above, examples include: other films bonded to polarizing films The protective film that is attached to the TFT layer of the organic EL display panel is usually called the protective film of the following protective film.

The resin film sticking system 1 is provided with a roller support part 20 and a sticking station 30.

The cut forming portion 22 is configured to form a cut 11e in the width direction of the resin film laminate 11 from the side of the optical film 11c to the depth of the interface between the adhesive layer 11b and the carrier film 11a. The formation of the cut 11e is performed by stopping the feeding of the resin film laminate 11 in the cut forming portion 22. That is, the feeding of the resin film laminate 11 is intermittently stopped at the cut formation portion 22, and the cutting is performed in the stopped state. As a result, the resin film laminate 11 is adjusted in the longitudinal direction of the laminate 11 A plurality of cuts 11e are formed at predetermined intervals. The predetermined interval of the cut 11e formed in the width direction of the resin film laminate 11, if the resin film laminate 11 has a predetermined width corresponding to the short side dimension of the shaped panel 31, is formed to correspond to the long side of the shaped panel 31 Size. As a result of the cut 11e, in the resin film laminate 11, as shown in FIG. 2, between the two adjacent cuts 11e in the longitudinal direction, a rectangular shaped adhesive including the optical film 11c and the adhesive layer 11b is formed.剂层的片11d.

As shown in FIGS. 1 and 2, the resin film laminate 11 guided to the position of the peeling member 35 is folded back into an acute angle at the leading edge of the peeling member 35. At this time, the rectangular adhesive layer-attached film sheet 11d including the optical film 11c and the adhesive layer 11b formed on the resin film laminate 11 is peeled off from the carrier film 11a and guided under the adhesive roller 33 side. The carrier film 11 a from which the adhesive layer-attached film sheet 11 d is peeled off is guided by the guide roller 26 and wound by the winding drive shaft 27. The winding drive shaft 27 is driven at a predetermined speed, and the feeding of the resin film laminate 11 is determined according to the winding speed. On the other hand, in the cut formation portion 22, the resin film laminate 11 is intermittently stopped, so a difference in the feed speed occurs. The tension roller mechanism 23 is provided to compensate for this difference in feed speed.

As shown in Figures 1 and 2, the shaped panel feeding mechanism 40 is provided with a suction and holding member 41, and the shaped panel 31 is sucked and held on the upper surface of the suction and holding member 41, as shown in FIG. 1 by the arrow The direction indicated by number A is conveyed through the sticking part 32. The feeding of the shaped panel 31 by the suction and holding member 41 is synchronized with the feeding of the resin film laminate 11, so that the tip of the resin film sheet 11d with the adhesive layer peeled off by the peeling member 35 is opposed to The front end of the shaped panel 31 sent to the sticking part 32 is controlled in a position-integrated manner. In the sticking part 32, the sticking roller mechanism 34 operates, and the sticking roller 33 presses the resin film sheet 11d with the adhesive layer against the shaped panel 31 on the suction holding member 41 to stick it.

Viewed in the feed movement direction of the suction holding member 41, a fixed-shaped panel conveying line 50 is arranged on the upstream side, and the fixed-shaped panel 31 is conveyed by the conveying line 50 to a position close to the fixed-shaped panel loading position 42. Above the fixed-shaped panel loading position 42, there is provided a fixed panel 31 for transferring the fixed-shaped panel 31 sent to a position close to the fixed-shaped panel loading position 42 by the fixed-shaped panel transfer line 50 on the suction holding member 41 located at the fixed-shaped panel loading position 42 Shaped panel loading mechanism 60. In addition, the pasting station 30 is provided with a resin film sheet removal position 43 for removing the resin film sheet 11d and the resin film sheet-attached configuration panel 31a, which is adjacent to the downstream side of the removal position 43, and is arranged A plastic film sheet-attached shaped panel delivery line 51. Above the delivery line 51 is a panel transfer mechanism 70 for transferring the resin film sheet-attached stereotype panel 31a to the resin film sheet-attached stereotype panel delivery line 51 from the resin film sheet-attached stereotype panel take-out position 43.

The details of the shaped panel feeding mechanism 40 are shown in FIGS. 4 and 5. Fig. 4 is a side view of the shaped panel feeding mechanism 40, and Fig. 5 is an end view as viewed in the direction of arrow V-V in Fig. 4. As shown in the figure, the shaped panel feeding mechanism 40 is provided on the base 44 with two guide rails 45 arranged in parallel with the direction indicated by the arrow A in FIG. 1. The suction holding member 41 is in the form of a rectangular flat plate, and is provided with four supporting legs 46 extending vertically downward. The lower end of the supporting leg 46 is connected to the lower supporting plate 47. On the lower surface of the lower support plate 47, a sliding member 48 that is fastened to a guide rail 45 on the base 44 and slidably moves along the guide rail 45 is fixed. There are two sliding members 48 for each of the pair of guide rails 45, for a total of four.

The shaped panel feeding mechanism 40 includes a suction and holding member driving mechanism 80. The suction and holding member driving mechanism 80 is arranged between a pair of guide rails 45 and is provided with a driving screw 81 extending parallel to the guide rail 45. The drive screw 81 is rotatably supported on the base 44 about its longitudinal axis. A nut member 82 screwed on the driving screw 81 is fixed to the lower support plate 47. The nut member 82 and the drive screw 81 form a ball/screw mechanism that engages with each other with low friction through a large number of balls arranged in the nut member 82. The end of the driving screw 81 is coupled to a servo motor 84 through a speed reducer 83, and the servo motor 84 is reversibly driven to rotate. As a result of this reversible rotational drive, the suction holding member 41 is driven in the feeding direction indicated by the arrow A and the opposite return direction thereof. That is, as a result of the drive screw 81 of the suction and holding member drive mechanism 80 being reversibly rotationally driven in the forward and reverse directions, the suction and holding member 41 is in the direction of arrow A in FIG. The fixed-shaped panel loading position 42 passes through the pasting station 30 and moves forward to the fixed-shaped panel removal position 43 with a resin film sheet. Next, the suction holding member 41 moves along the return path in the return direction opposite to the arrow A, with the plastic film sheet-attached shaped panel taking-out position 43 as the turn-back end. The return path is the same path as the forward road, and the suction holding member 41 is returned to the fixed-shaped panel mounting position 42 which is the beginning end of the forward road through the sticking station 30.

The suction holding member 41 is in the form of a suction plate in which the shaped panel 31 reproduced on the suction holding member 41 by the shaped panel loading mechanism 60 is sucked by suction and held without positional deviation. The suction holding member 41 composed of the suction plate is preferably formed to have a size that can cover the entire surface of the shaped panel 31 to be sucked and held. An embodiment of the suction holding member 41 is shown in Fig. 6 (a) (b).

The frame member 41c is formed integrally with the bottom plate 41d, and the bottom plate 41d has suction ports 41e formed at positions corresponding to each of the plurality of suction plate pieces 41a. Each suction port 41e is connected to a collection pipe 41h through a branch pipe 41g having a valve 41f, and the collection pipe 41h is connected to a suction source P like a vacuum pump.

By providing the partition member 41b and the branch pipe 41g with the valve 41f, only the suction plate 41a that appropriately controls the opening and closing of the valve 41f to act on the suction force is selected, not only the shaped panel 31 corresponding to the size of the frame member 41c, but also The size and small size of the shaped panel 31 can also be reliably sucked and maintained. However, the suction plate 41a may be formed in a single piece structure corresponding to the size of the frame member 41c. The adsorption plate 41a can be formed of a porous material. Examples of porous materials include porous ceramics or porous films of high molecular weight resins. As an example of the porous ceramics that can be used in this embodiment, there is a micro-diameter porous ceramic NPP-3D manufactured by Japan Tungsten Co., Ltd. In addition, as for the porous resin film, there is a high-molecular-weight polyethylene porous film "SUNMAP LC-T" manufactured by Nitto Denko Corporation. In addition, in this embodiment, a perforated plate having fine through holes formed on the entire surface can also be used. If a porous plate is used, the diameter of the through holes is preferably 3mm or less, and the spacing of the holes is preferably 30mm or less. If the hole diameter is larger than 3 mm, there is a possibility that traces of holes remain in the shaped panel 31 held by the suction holding member 41. In addition, if the interval of the holes is too large, sufficient attractive force cannot be obtained, and there is a risk of maintaining uncertainty.
