Then, by processing the image taken by this camera, it is inspected whether or not the foreign matter is mixed on the OLED sheet 111.

<8. Sticking device>
The sticking apparatus will be described. A sticking apparatus can use a well-known apparatus, for example, a fixing part which fixes a polarizing sheet laminated body, a moving mechanism which moves this fixing part, a protective sheet from the polarizing sheet laminated body 12 fixed to the fixing part And a peeling portion for peeling 122. A pressure-sensitive adhesive sheet is disposed on the lower surface of the fixing portion, and the polarizing sheet laminate 12 attached to the pressure-sensitive adhesive sheet is conveyed by the moving mechanism onto the support device 3 at the attachment position. Then, the moving mechanism is operated to attach the polarizing sheet 121 to the OLED sheet 111. Moreover, the 2nd conveying apparatus (illustration omitted) which conveys the OLED sheet 111 with which the polarizing sheet 121 was stuck is provided.

<9. Operation of sticking system>
Next, the operation of the sticking system configured as described above will be described. First, the rotation member is driven to arrange the four supporting devices at the arrangement position, the peeling position, the inspection position, and the sticking position, respectively.

<9-1. Processing at the placement position>
First, the OLED sheet laminate 11 is placed on the support device 3 placed at the placement position. This point will be described with reference to FIGS. 8A and 8B. First, the rotational positions of the delivery roll 321 and the take-up roll 333 are fixed. As a result, the support sheet 34 is held in a tensioned state between the delivery roll 321 and the take-up roll 333. Next, the drive unit 36 is driven to engage the engagement member 362 with the connection member 358 of the movement unit 35. In this state, the movable portion 361 is moved radially inward to move the moving unit 35 to the first position. Next, the first transport device is driven. The OLED sheet laminate 11 is adsorbed on the lower surface of the adsorption member 51 of the first transport device, and the adsorption member 51 is moved by the moving mechanism and positioned on the support device 3. Here, for convenience of description, the radially inward edge of the OLED sheet laminate 11 disposed in the support device 3 is referred to as a first edge 115, and the radially outward edge is a second edge. It shall call 116. That is, the OLED sheet laminate 11 is formed in a rectangular shape having the first end 115 and the second end 116 at both ends in the radial direction.

  Then, as shown in FIG. 8A, in the adsorption member 51, the first edge 115 of the rectangular OLED sheet laminate 11 is parallel to the axial center of the moving roller 354 of the moving unit 35 on the supporting device 3. And, it is positioned so as to be located near the top of the moving roller 354. Next, the adsorbing member is moved downward to a position where the OLED sheet laminate 11 substantially contacts the support sheet 34 stretched around the moving roller 354. Subsequently, the drive unit 36 is driven to move the moving unit 35 radially outward. As a result, the moving roller 354 and the first driven roller 355 move radially outward, and accordingly, the support sheet 34 is pressed radially outward by the moving roller 355, and the horizontal portion of the support sheet 34 is radially moved. It will extend outward. On the other hand, in the support sheet 34, the portion between the second driven roller 355 and the third driven roller 331 becomes shorter. Therefore, in the support sheet 34, the length between the feed roll 321 and the take-up roll 333 does not change. Thus, the lower surface of the OLED sheet laminate 11 is sequentially bonded from the first edge 115 to the second edge 116 to the horizontal portion of the radially extending support sheet 34. Further, since the support sheet 34 is pressed from below against the OLED sheet laminate 11 by the moving roller 354, the adhesive layer of the support sheet 34 is firmly adhered to the OLED sheet laminate 11.

  Thus, in the process of moving the moving unit 35 from the first position to the second position, the support sheet 34 is bonded to the OLED sheet laminate 11 sequentially from the radially inward to the outward. Then, as shown in FIG. 8B, when the moving unit 35 moves to the second position, the OLED sheet laminate 11 is placed on the support sheet 34 from the first edge 115 to the entire second edge 116. Be glued. Further, the support plate 353 moves radially outward together with the moving roller 354, and when the moving unit 35 moves to the second position, the support plate 353 is disposed immediately below the OLED sheet laminate 11. Next, the pressing tool 312 of the main body 31 is driven to push up the pressing member 313 upward, and fixed to the fixing tool 357 of the moving unit 35. Thus, the moving unit 35 is fixed at the second position. Subsequently, the engagement member 362 of the drive unit 36 is driven downward to separate the engagement member 362 from the connection member 358. The drive unit 36 is thereby separated from the support device 3. Thereafter, the suction of air by the suction member is stopped, and the suction member is separated from the support device 3. The OLED sheet laminate 11 is disposed on the support device 3 by the above-described steps.

  When the moving unit 35 returns to the first position, it operates from the state of FIG. 8B to the state of FIG. 8A. At this time, the first driven roller 355 presses the support sheet 34 inward in the radial direction, whereby the portion between the second driven roller 355 and the third driven roller 331 in the support sheet 34 becomes long, and the moving roller The length of the horizontal portion between 354 and the second driven roller 322 is shortened.

  In addition, the adhesive layer of the support sheet 34 is reduced in adhesive strength when the OLED sheet laminate 11 is attached many times, so that the take-up roll 333 is driven at an appropriate timing when the OLED sheet laminate 11 is not disposed. And take up the support sheet 34. That is, when the take-up roll 333 is driven and the support sheet 34 is taken up, a new support sheet 34 is delivered from the delivery roll 321, so that the horizontal portion where the OLED sheet laminate 11 is disposed has new adhesion. Layers appear. Therefore, it is possible to prevent peeling of the OLED sheet laminate 11 due to the decrease in the adhesive force.

<9-2. Processing at the peeling position>
Next, the rotation member 21 is rotated to move the supporting device 3 on which the OLED sheet is disposed to the peeling position. Here, the moving mechanism of the peeling device is driven to bond the bonding member 42 to the first corner of the protective sheet 112 as shown in FIG. Next, the movement mechanism is moved to move the adhesive member 42 together with the protective sheet 112 in the direction S to the second corner. Thereby, the protective sheet 112 is peeled off from the OLED sheet 111.

<9-3. Processing at inspection position>
Subsequently, the rotation member 21 is rotated, the protective sheet 112 is peeled off, and the supporting device 3 on which the exposed OLED sheet 111 is disposed is moved to the inspection position. Then, the camera is moved on the OLED sheet 111 for photographing, and the image processing is performed to inspect the inclusion of foreign matter. If contamination of foreign matter is confirmed, the OLED sheet 111 is discarded.

<9-4. Processing at sticking position>
And when mixing of a foreign material is not confirmed, rotation member 21 is rotated and support device 3 is moved to a sticking position. Then, the protective sheet 122 on the lower side of the polarizing sheet laminate 12 is peeled off from the polarizing sheet laminate 12 fixed to the lower surface of the fixing part by the peeling part. Next, the moving mechanism places the polarizing sheet 121 on the OLED sheet 111 with the polarizing sheet 121 exposed downward, and affixes the polarizing sheet 121 on the top surface of the OLED sheet 111. Thereafter, the OLED sheet 111 to which the polarizing sheet 121 is attached is moved from the support device 3 to another process by the second transport device.

<10. Feature>
As described above, according to the support device 3 according to the present embodiment, the following effects can be obtained. First, the OLED sheet laminate 11 is supported on the support sheet 34 by the adhesive layer over the entire surface. Therefore, the OLED sheet laminate 11 is firmly fixed on the support sheet 34 until it is attached to the support device 3 at the arrangement position and then the polarizing sheet 121 is attached at the attachment position. Therefore, it is possible to prevent peeling, warping, and the like of the OLED sheet laminate 11.

  In particular, since the thickness of the OLED sheet laminate 11 is small, for example, in a conventional device that supports the laminate by negative pressure, air holes may cause dents in the laminate, or in portions without air holes. It may not be fixed sufficiently. On the other hand, in the supporting device according to the present embodiment, since the entire surface of the OLED sheet laminate 11 is supported by the adhesive layer of the flat supporting sheet 34, it is possible to prevent the formation of dents and the like. Since the entire surface of the OLED sheet laminate 11 can be fixed uniformly, the occurrence of warpage can also be prevented. Furthermore, even if the shape of the OLED sheet laminate 11 changes, it can be firmly fixed.

  Further, in the supporting device 3, while moving the moving roller 354 in the radial direction, the supporting sheet 34 is bonded in order from the first edge to the second edge of the OLED sheet laminate 11. Therefore, air can be prevented from mixing between the OLED sheet laminate 11 and the support sheet 34. Therefore, the entire surface of the thin OLED sheet laminate 11 can be fixed to the support sheet 34 uniformly.

  A supporting plate 353 is attached to the moving unit 35, and when the moving unit 35 moves to the second position, the supporting plate 353 is moved immediately below the OLED sheet laminate 11. Therefore, since the OLED sheet laminate 11 is supported not only by the support sheet 34 but also by the support plate 353, deformation occurs even when the OLED sheet 111 is pressed from above when the polarizing sheet 121 is attached to the OLED sheet 111. As a result, the polarizing sheet 121 can be appropriately attached to the OLED sheet 111.

<11. Modified example>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, A various change is possible unless it deviates from the meaning. The following modifications can be combined as appropriate.

<11-1>
Although the sticking system which sticks the polarizing sheet 121 to the OLED sheet 111 was demonstrated in the said embodiment, a sticking system can be changed suitably. For example, the peeling device, the inspection device, and the sticking device described in the above embodiments are merely examples, and other devices having similar functions can also be used. Moreover, although the peeling apparatus and the test | inspection apparatus are provided, it is not necessary to provide these. For example, if the protective sheet has been removed in advance, the peeling device is unnecessary. Furthermore, in addition to affixing the polarizing sheet 121 to the OLED sheet 111, it can be used to affix other sheets.

Although the example which applied the support apparatus of this invention to the sticking system was shown in the said embodiment, the use of this support apparatus is not limited to this. That is, it can apply suitably to the use which supports a thin sheet. Thus, the support device of the present invention can be used to place other thin sheets, not limited to the OLED sheet 111.

<11-3>
The configuration of the holding mechanisms 32 and 33 is not particularly limited as long as the longitudinal ends of the support sheet 34 can be supported. Therefore, the number, position, etc. of the rollers can be changed as appropriate. Alternatively, the delivery roll 321 may be provided in the second holding mechanism 33, and the take-up roll 333 may be provided in the first holding mechanism 32. In addition, the delivery roll 321 and the take-up roll 333 may not be provided, and only the both ends of the support sheet 34 may be fixed. In that case, for example, the support sheet 34 itself is replaced. be able to.

<11-4>
The operation start position and the operation end position of the moving roller 354 when arranging the OLED sheet 111 are not particularly limited, and can be appropriately changed according to the type, size, and the like of the OLED sheet 111.

<11-5>
The configuration of the moving unit 35 is not particularly limited as long as at least the moving roller 354 can move in the radial direction. Therefore, the moving unit 35 can be configured by only the moving roller 354, and the fixing tool 357, the support plate 353, and the first driven roller 355 are not necessarily required. For example, the support plate 353 is not necessarily required if only the OLED sheet 111 is supported, without another sheet material application process. The drive unit 36 for moving the moving unit 35 is provided below the support device 3, but may be disposed at any position as long as the moving unit 35 can be moved.

<11-6>
In the above embodiment, the movable sheet 354 is configured to rotate while pressing the support sheet 34 radially outward by the movement roller 354. However, instead of the movement roller 354, a plate-like member is used, and the support sheet 34 is Can also be pressed. At this time, for example, it is preferable that the end face of the plate-like member is formed in a circular arc shape in cross section, and the support sheet 34 smoothly moves on the end face of the plate-like member. Similarly, since the first driven roller 355 plays a role of pressing the support sheet 34 radially inward, this can also be replaced by a plate-like member. In addition to the plate-like members, various members can be used as long as the support sheet 34 can be pressed and the support sheet 34 can be moved smoothly.

<11-7>
In the above embodiment, the support device 3 and the sticking unit are disposed such that the adhesive layer of the support sheet 34 faces upward, but the orientation of the arrangement is not particularly limited. For example, the support device 3 and the sticking unit may be arranged such that the adhesive layer extends in the vertical direction, or the adhesive layer faces downward.
