    Referring to FIG. 1, the third alignment device 17 inverts the front and back surfaces of the second single-sided bonding panel P12 with the display surface side of the liquid crystal panel P as the upper surface, and the backlight side of the liquid crystal panel P as the upper surface. In addition, the same alignment as that of the first and second alignment devices 11 and 14 is performed. That is, the third alignment device 17 is based on the inspection data in the optical axis direction stored in the control device 20 and the imaging data of the camera C, and the component width direction of the second single-sided bonding panel P12 with respect to the third bonding device 18. And positioning in the rotation direction. In this state, the second single-sided bonding panel P <b> 12 is introduced into the bonding position of the third bonding device 18.

    The 3rd bonding apparatus 18 is the lower surface of the 2nd single-sided bonding panel P12 conveyed above with respect to the upper surface of the elongate 3rd optical member sheet | seat F3 (optical member sheet | seat) introduced into the bonding position. (The display surface side of the liquid crystal panel P) is bonded. The 3rd bonding apparatus 18 conveys the 3rd optical member sheet | seat F3 along the longitudinal direction, unwinding the 3rd optical member sheet | seat F3 from the 3rd original fabric roll R3 which wound the 3rd optical member sheet | seat F3. The conveying apparatus 18a and the pinching roll 18b which bonds the lower surface of the 2nd single-sided bonding panel P12 which the roller conveyor 5 conveys to the upper surface of the 3rd optical member sheet | seat F3 which the conveying apparatus 18a conveys are provided.

    The transport device 18a includes a roll holding unit 18c that holds the third original roll R3 around which the third optical member sheet F3 is wound, and that feeds the third optical member sheet F3 along its longitudinal direction, and a pressure roll 18b. And a third recovery part 18d that recovers an excess portion of the third optical member sheet F3 that has passed through the third cutting device 19 located on the downstream side of the panel conveyance.

    The pinching roll 18b has a pair of pasting rollers arranged with their axial directions parallel to each other. A predetermined gap is formed between the pair of bonding rollers, and the gap is the bonding position of the third bonding device 18. In the gap, the second single-sided bonding panel P12 and the third optical member sheet F3 are overlapped and introduced. These 2nd single-sided bonding panels P12 and the 3rd optical member sheet | seat F3 are sent out to a panel conveyance downstream, being pinched between the said bonding rollers. Thereby, the 3rd bonding sheet | seat F23 which bonded the several 2nd single-sided bonding panel P12 continuously on the upper surface of the elongate 3rd optical member sheet | seat F3 is formed.

    The 3rd cutting device 19 is located in a panel conveyance downstream rather than the pinching roll 18b, and cut | disconnects the 3rd optical member sheet | seat F3. The 3rd cutting device 19 is a laser processing machine similar to the 2nd cutting device 16, and the 3rd optical member sheet | seat F3 is followed along the outer periphery of the bonding surface of the 3rd optical member sheet | seat F3 and liquid crystal panel P ( For example, along the outer peripheral edge of the liquid crystal panel P, it is cut endlessly.

    By the cutting | disconnection of the 3rd cutting device 19, the double-sided bonding panel P13 (the optical member bonding body, the 2nd optical member bonding body) by which the 3rd optical member F13 was bonded to the lower surface of the 2nd single-sided bonding panel P12 is formed. (See FIG. 8). Moreover, the double-sided bonding panel P13 and the excess part of the 3rd optical member sheet | seat F3 which a part (3rd optical member F13) corresponding to a bonding surface is cut off, and remain in a frame shape are isolate | separated at this time. A plurality of surplus portions of the third optical member sheet F3 are connected to form a ladder like the surplus portions of the second optical member sheet F2 (see FIG. 2), and the surplus portions are wound around the third recovery portion 18d.

    After the double-sided bonding panel P13 is inspected for defects (such as poor bonding) through a defect inspection device (not shown), it is transported to the downstream process and subjected to other processes.

    Here, in general, a long optical film (corresponding to each optical member sheet F1, F2, F3) is manufactured by uniaxially stretching a resin film dyed with a dichroic dye, and the direction of the optical axis of the optical film Generally coincides with the stretching direction of the resin film. However, the optical axis of the optical film is not uniform throughout the optical film, but varies slightly in the width direction of the optical film.

For this reason, when bonding a some optical display component to the optical film in the width direction, it is desirable to align an optical display component according to the optical axis direction of an optical film.
This is effective in that the variation in the optical axis of each optical display device is suppressed and the color and contrast are enhanced.

    An optical film as a polarizing film is dyed with, for example, iodine or a dichroic dye in order to block light other than light that vibrates in one direction. In addition, a peeling film and a protective film may be further laminated | stacked on the optical film.

    The inspection device for inspecting the optical axis direction of the optical film is disposed at a position near the other surface of the front and back surfaces of the optical film, and a light source disposed at a position near one of the front and back surfaces of the optical film. And an analyzer disposed on the opposite side of the light source. The analyzer receives the light irradiated from the light source and transmitted through the optical film, and detects the optical axis of the optical film by detecting the intensity of this light. The analyzer can be moved in the width direction of the optical film, for example, and the optical axis can be inspected at an arbitrary position in the width direction of the optical film (a position selected according to use conditions).

    In the case of this embodiment, the inspection data in the optical axis direction of each optical member sheet F1, F2, F3 obtained by the inspection apparatus is associated with the longitudinal direction position and the width direction position of each optical member sheet F1, F2, F3. And stored in the memory of the control device 20. After this inspection, the optical member sheets F1, F2, and F3 are wound up to form the original rolls R1, R2, and R3, respectively. Hereinafter, the optical member sheets F1, F2, and F3 are collectively referred to as the optical member sheet FX, the liquid crystal panel P that is bonded to the optical member sheets F1, F2, and F3, and the single-sided bonding panels P11 and P12 are collectively referred to as the optical display member PX. There are things to do.

    Here, the polarizer film constituting the optical member sheet FX is formed by, for example, uniaxially stretching a PVA film dyed with a dichroic dye, but the PVA film has uneven thickness or dichroism when stretched. Due to uneven coloring of the dye, etc., there is a tendency that a difference in the optical axis direction occurs between the inner side in the width direction and the outer side in the width direction of the optical member sheet FX.

    Therefore, in the present embodiment, based on the inspection data of the in-plane distribution of the optical axis in each part of the optical member sheet FX stored in advance in the control device 20, the alignment of the optical display component PX to be bonded to these is performed. The optical display component PX is bonded to the optical member sheet FX.

    Specifically, for example, the optical axis having the maximum angle and the minimum optical axis with respect to a predetermined reference axis (longitudinal axis or the like) is found in the plane of the portion where the optical display component PX is bonded to the optical member sheet FX. The optical display component PX is aligned on the basis of the axis that bisects the angle formed by these optical axes as an average optical axis of the part.

    Accordingly, even when the optical display component PX is bonded to a different position in the width direction of the optical member sheet FX, the variation in the optical axis direction of the optical member sheet FX with respect to the reference position of the optical display component PX can be suppressed. The tolerance can be approximately 0 ° (allowable tolerance is ± 0.25 °).

    Note that the optical axis direction may be detected while the optical member sheet FX is unwound, and the optical display component PX may be aligned based on the detection data. The various alignment methods described above are not limited to the case where the optical axis direction of the optical member sheet FX is 0 ° and 90 °, and the optical axis direction is set to an arbitrary angle (an angle corresponding to the purpose of the optical display component). It is also applicable when

    FIG. 3 shows an example in which three optical display components PX are aligned and bonded to an optical member sheet FX having a relatively wide width in the width direction. The present invention is not limited to the example shown in FIG. 3, and a configuration in which two or less or four or more optical display components PX are aligned and bonded in the width direction of the optical member sheet FX may be employed, and may be relatively wide. A configuration may be adopted in which a plurality of narrow optical member sheets FX are arranged in the width direction and the optical display component PX is bonded to each of them.

    Referring to FIG. 4, the liquid crystal panel P includes a rectangular first substrate P1 made of, for example, a TFT substrate, a second rectangular substrate P2 disposed opposite to the first substrate P1, and a first substrate P1. And a liquid crystal layer P3 sealed between the second substrate P2. For convenience of illustration, hatching of each layer in the cross-sectional view may be omitted.

    Referring to FIGS. 6 and 7, the first substrate P1 has three sides of the outer periphery of the first substrate P1 along the corresponding three sides of the second substrate P2, and the remaining one side of the outer periphery is the second substrate. It protrudes outside the corresponding side of P2. Thereby, the electrical component attachment part P5 which protrudes outside the 2nd board | substrate P2 is provided in the said one side of the 1st board | substrate P1.

    With reference to FIG.5 and FIG.7, the 2nd cutting device 16 is the bonding surface of the laminated body of the 2nd optical member sheet | seat F2 and the sheet piece F1S, and the liquid crystal panel P which were detected with the detection apparatus mentioned later. The first and second optical member sheets F1 and F2 are cut along the outer peripheral edge. FIG. 5 shows an imaging device 43 constituting the detection device. Moreover, the 3rd cutting device 19 cut | disconnects the 3rd optical member sheet | seat F3 along the outer periphery of the bonding surface of the 3rd optical member sheet | seat F3 and liquid crystal panel P detected by the detection apparatus mentioned later.

Laser cutting is done.

  The detection of the outer peripheral edge of the bonding surface and the cutting by the cutting device are performed in detail as follows.

  FIG. 17 is a schematic diagram of the first detection device 41 that detects the outer periphery of the bonding surface. In FIG. 17, for convenience, the side of the liquid crystal panel P on which the sheet piece F1S is bonded is the upper side, and the configuration of the first detection device 41 is shown upside down.

  The 1st detection apparatus 41 with which the film bonding system 1 of this embodiment is provided is the bonding surface (henceforth 1st bonding surface SA1) of the liquid crystal panel P and the sheet piece F1S in the 2nd bonding sheet | seat F22.

And a control unit 45 that performs an operation for this purpose.

  Such a first detection device 41 is provided on the upstream side of the panel conveyance of the second cutting device 16 in FIG. 1, and is provided between the pinching roll 15 b and the second cutting device 16.

  The imaging device 43 is fixedly arranged inside the first bonding surface SA1 with respect to the outer peripheral edge ED, and the normal line of the first bonding surface SA1 and the normal line of the imaging surface 43a of the imaging device 43 are arranged. , And an angle θ (hereinafter referred to as an inclination angle θ of the imaging device 43). The imaging device 43 takes an image of the outer peripheral edge ED from the side where the sheet piece F1S is bonded in the second bonding sheet F22 with the imaging surface 43a facing the outer peripheral edge ED.

  The inclination angle θ of the imaging device 43 is preferably set so that the outer peripheral edge of the first substrate P1 that forms the first bonding surface SA1 can be reliably imaged. For example, when the liquid crystal panel P is formed by so-called multiple chamfering, in which the mother panel is divided into a plurality of liquid crystal panels, the liquid crystal panel P is shifted to the outer peripheral edge of the first substrate P1 and the second substrate P2 constituting the liquid crystal panel P May occur, and the end surface of the second substrate P2 may be displaced outward from the end surface of the first substrate P1. In such a case, the inclination angle θ of the imaging device 43 is preferably set so that the outer periphery of the second substrate P2 does not enter the imaging field of the imaging device 43.

  In such a case, the inclination angle θ of the imaging device 43 is a distance H between the first bonding surface SA1 and the center of the imaging surface 43a of the imaging device 43 (hereinafter referred to as the height H of the imaging device 43). It is preferable to set so that it may fit. For example, when the height H of the imaging device 43 is 50 mm or more and 100 mm or less, the inclination angle θ of the imaging device 43 is preferably set to an angle in the range of 5 ° or more and 20 ° or less. However, when the deviation amount is empirically known, the height H of the imaging device 43 and the inclination angle θ of the imaging device 43 can be obtained based on the deviation amount. In the present embodiment, the height H of the imaging device 43 is set to 78 mm, and the inclination angle θ of the imaging device 43 is set to 10 °.

  The inclination angle θ of the imaging device 43 may be 0 °. FIG. 18 is a schematic diagram illustrating a modification of the detection device 41, and is an example in the case where the inclination angle θ of the imaging device 43 is 0 °. Also in FIG. 18, for convenience, the side of the liquid crystal panel P on which the sheet piece F1S is bonded is the upper side, and the configuration of the first detection device 41 is shown upside down. As shown in FIG. 18, each of the imaging device 43 and the illumination light source 44 may be disposed at a position overlapping the outer peripheral edge ED along the normal direction of the first bonding surface SA1.

  A distance H1 between the first bonding surface SA1 and the center of the imaging surface 43a of the imaging device 43 (hereinafter referred to as a height H1 of the imaging device 43) detects the outer peripheral edge ED of the first bonding surface SA1. It is preferable to set the position at an easy position. For example, the height H1 of the imaging device 43 is preferably set in a range of 50 mm or more and 150 mm or less.

  The illumination light source 44 is fixed and arranged on the side opposite to the side where the sheet piece F1S in the second bonding sheet F22 is bonded. The illumination light source 44 is arrange | positioned with the attitude | position which inclined outside the 1st bonding surface SA1 rather than the outer periphery ED with respect to the normal line direction of 1st bonding surface SA1. In the present embodiment, the optical axis of the illumination light source 44 and the normal line of the imaging surface 43a of the imaging device 43 are parallel.

  In addition, the illumination light source 44 may be arrange | positioned at the side (namely, the same side as the imaging device 43) by which the sheet piece F1S in the 2nd bonding sheet | seat F22 was bonded.

  Further, if the outer peripheral edge ED imaged by the imaging device 43 is illuminated by the illumination light emitted from the illumination light source 44, the optical axis of the illumination light source 44 and the normal line of the imaging surface 43a of the imaging device 43 intersect. It may be.

  FIG. 19 is a plan view showing a position where the outer peripheral edge of the bonding surface is detected. An inspection area CA is set on the conveyance path of the second bonding sheet F22 shown in FIG. Inspection area | region CA is set in the position corresponding to the outer periphery ED of 1st bonding surface SA1 in liquid crystal panel P conveyed. In FIG. 19, inspection area | region CA is set to four places corresponding to the four corners of 1st bonding surface SA1 of planar view rectangle, and the corner | angular part of 1st bonding surface SA1 is detected as outer periphery ED. It is the composition to do. In FIG. 19, the hook-shaped part corresponding to a corner | angular part is shown as outer periphery ED among the outer periphery of 1st bonding surface SA1.

  The first detection device 41 in FIG. 17 detects the outer peripheral edge ED in the four inspection areas CA. Specifically, the imaging device 43 and the illumination light source 44 are arranged in each inspection area CA, and the first detection device 41 has a corner portion of the first bonding surface SA1 for each liquid crystal panel P to be transported. And the outer peripheral edge ED is detected based on the imaging data. Data of the detected outer peripheral edge ED is stored in the control unit 45 shown in FIG.

  In addition, if the outer periphery of 1st bonding surface SA1 is detectable, the setting position of test | inspection area | region CA is not restricted to this. For example, each inspection area | region CA may be arrange | positioned in the position corresponding to a part (for example, center part of each side) of each edge | side of 1st bonding surface SA1. In this case, each side (four sides) of the first bonding surface SA1 is detected as an outer peripheral edge.

  In addition, the imaging device 43 and the illumination light source 44 are not limited to the configuration arranged in each inspection area CA, but are configured to be able to move along a movement path that is set along the outer peripheral edge ED of the first bonding surface SA1. It may be. In this case, it is only necessary that one imaging device 43 and one illumination light source 44 are provided.

  The cutting positions of the sheet piece F1S and the second optical member sheet F2 by the second cutting device 16 are adjusted based on the detection result of the outer peripheral edge ED of the first bonding surface SA1. The control unit 45 shown in FIG. 14 has the first optical member F11 on the outside of the liquid crystal panel P (the outside of the first bonding surface SA1) based on the stored data of the outer peripheral edge ED of the first bonding surface SA1. The cut positions of the sheet piece F1S and the second optical member sheet F2 are determined so as not to protrude. The second cutting device 16 cuts the sheet piece F1S and the second optical member sheet F2 at the cutting position determined by the control unit 45.

  Returning to FIG. 1, the second cutting device 16 is provided on the downstream side of the panel conveyance with respect to the first detection device 41. The 2nd cutting device 16 detected the part corresponding to 1st bonding surface SA1 among the sheet piece F1S and 2nd optical member sheet | seat F2 which were bonded by liquid crystal panel P, and the excess part of the outer side. The first optical member F11 and the second optical member F12 (see FIG. 8) having a size corresponding to the first bonding surface SA1 are cut out along the outer peripheral edge ED. Thereby, the 2nd single-sided bonding panel P12 by which the 1st and 2nd optical members F11 and F12 were piled up and bonded on the upper surface of liquid crystal panel P is formed.

  Here, “the portion corresponding to the first bonding surface SA1” means that the outer shape of the liquid crystal panel P is equal to or larger than the size of the display area of the opposing liquid crystal panel P in the sheet piece F1S and the second optical member sheet F2. It is a region that is equal to or smaller than the size of the contour shape in plan view and that avoids functional parts such as electrical component mounting portions in the liquid crystal panel P.

  In the present embodiment, the surplus portion is laser-cut along the outer peripheral edge of the liquid crystal panel P at three sides excluding the functional portion in the liquid crystal panel P having a rectangular shape in plan view, and the liquid crystal panel P at one side corresponding to the functional portion. It is possible to adopt a configuration in which the surplus portion is laser-cut at a position that appropriately enters the display region P4 side from the outer peripheral edge. For example, when the first substrate P1 is a TFT substrate, it is possible to adopt a configuration in which a cut is made at a position shifted from the outer peripheral edge of the liquid crystal panel P to the display region P4 side by a predetermined amount so as to exclude the functional portion on one side corresponding to the functional portion.

  FIG. 20 is a schematic diagram of the second detection device 42 that detects the outer peripheral edge of the bonding surface. 20, for the sake of convenience, the side of the liquid crystal panel P on which the third optical member sheet F3 is bonded is the upper side, and the configuration of the second detection device 42 is shown upside down. The 2nd detection apparatus 42 with which the film bonding system 1 of this embodiment is provided is the bonding surface (henceforth, 2nd bonding surface SA2) of liquid crystal panel P and the 3rd optical member sheet | seat F3 in the 3rd bonding sheet | seat F23. The imaging device 43 that captures an image of the outer peripheral edge ED, the illumination light source 44 that illuminates the outer peripheral edge ED, and the image captured by the imaging device 43 are stored, and the outer peripheral edge ED is based on the image. And a control unit 45 that performs a calculation for detecting. The second detection device 42 has the same configuration as the first detection device 41 described above.

  Such a second detection device 42 is provided on the upstream side of the panel conveyance of the third cutting device 19 in FIG. 1, and is provided between the pinching roll 18 b and the third cutting device 19. The 2nd detection apparatus 42 detects the outer periphery ED of 2nd bonding surface SA2 similarly to the above-mentioned 1st detection apparatus 41 in the test | inspection area | region set on the conveyance path | route of the 3rd bonding sheet | seat F23.

  The cutting position of the third optical member sheet F3 by the third cutting device 19 is adjusted based on the detection result of the outer peripheral edge ED of the second bonding surface SA2. The control unit 45 shown in FIG. 17 has the third optical member F13 on the outside of the liquid crystal panel P (the outside of the second bonding surface SA2) based on the stored data of the outer peripheral edge ED of the second bonding surface SA2. The cut position of the third optical member sheet F3 is determined so as not to protrude. The third cutting device 19 cuts the third optical member sheet F3 at the cutting position determined by the control unit 45.

  The 3rd cutting device 19 uses the part corresponding to 2nd bonding surface SA2 among the 3rd optical member sheets F3 bonded by liquid crystal panel P, and the excess part of the outer side to the detected outer periphery ED. The third optical member F13 (see FIG. 8) having a size corresponding to the second bonding surface SA2 is cut out. Thereby, the double-sided bonding panel P13 by which the 3rd optical member F13 was bonded by the upper surface of the 2nd single-sided bonding panel P12 is formed.

  Here, “the part corresponding to the second bonding surface SA2” means that the outer shape of the liquid crystal panel P (contour in plan view) is not less than the size of the display area of the liquid crystal panel P facing the third optical member sheet F3. It is an area that is equal to or less than the size of the shape) and that avoids a functional part such as an electric component mounting portion in the liquid crystal panel P.

    As shown in FIG. 10, when the resin optical member sheet FX is laser-cut alone, the cut end t of the optical member sheet FX may be swollen or wavy due to thermal deformation. For this reason, when the optical member sheet FX after laser cutting is bonded to the optical display component PX, poor bonding such as air mixing and distortion is likely to occur in the optical member sheet FX.

    On the other hand, as shown in FIG. 9, in this embodiment in which the optical member sheet FX is laser-cut after the optical member sheet FX is bonded to the liquid crystal panel P, the cut end t of the optical member sheet FX is the glass surface of the liquid crystal panel P. Is backed up. For this reason, since the swelling of the cut end t of the optical member sheet FX, undulation or the like does not occur, and the optical member sheet FX is bonded to the liquid crystal panel P, the bonding failure cannot occur.

    The deflection width (tolerance) of the cutting line of the laser processing machine is smaller than that of the cutting blade. Therefore, in this embodiment, the width of the frame portion G is larger than that in the case of cutting the optical member sheet FX using the cutting blade. The liquid crystal panel P can be reduced in size and / or the display area P4 can be increased in size. Such an optical member sheet is effective for application to a high-function mobile device that requires an enlargement of the display screen while the size of the housing is limited, such as a recent smartphone or tablet terminal.

    In addition, when the optical member sheet FX is cut into a sheet piece aligned with the display region P4 of the liquid crystal panel P and then bonded to the liquid crystal panel P, the dimensional tolerances of the sheet piece and the liquid crystal panel P, and their relative bonding Since the positional dimensional tolerances overlap, it is difficult to reduce the width of the frame portion G of the liquid crystal panel P (it is difficult to enlarge the display area).

    On the other hand, when the optical member sheet FX is bonded to the liquid crystal panel P and then cut in accordance with the display region P4, only the runout tolerance of the cutting line needs to be considered, and the width tolerance of the frame portion G can be reduced. (± 0.1 mm or less). Also in this respect, the width of the frame part G of the liquid crystal panel P can be reduced (the display area can be enlarged).

    Further, by cutting the optical member sheet FX with a laser instead of a blade, the cutting force is not input to the liquid crystal panel P, and it becomes difficult for cracks and chips to occur at the edge of the substrate of the liquid crystal panel P, such as a heat cycle. The durability against is improved. Similarly, since there is no contact with the liquid crystal panel P, there is little damage to the electrical component mounting portion P5.

    As shown in FIG. 6, when laser cutting the optical member sheet FX (third optical member sheet F3 in FIG. 6), for example, a laser cut start point pt1 is set on the extension of one long side of the display area P4, and this First, the cutting of the one long side is started from the starting point pt1. The end point pt2 of the laser cut is set at a position where the laser goes around the display area P4 and reaches the extension of the short side on the start point side of the display area P4. The start point pt1 and the end point pt2 are set so as to be able to withstand the tension when the optical member sheet FX is wound, leaving a predetermined connection allowance in the surplus portion of the optical member sheet FX.

    As described above, the optical display device production system in the above embodiment is a film bonding system that forms a part of the optical display device production system in which the optical members F11, F12, and F13 are bonded to the liquid crystal panel P. 1, the plurality of liquid crystal panels P transported on the roller conveyor 5 has a strip shape having a width larger than the width of the display region P4 of the liquid crystal panel P in the component width direction orthogonal to the transport direction of the liquid crystal panel P. While unwinding the optical member sheets F1, F2, and F3 from the raw fabric rolls R1, R2, and R3, a plurality of the liquid crystal panels P are bonded to the optical member sheets F1, F2, and F3 to bond sheets F21 and F22. , F23 forming bonding devices 12, 15, 18 and the bonding sheets F22, F23, for each of the plurality of liquid crystal panels P, the light In the detection devices 41 and 42 for detecting the outer peripheral edge of the bonding surface between the member sheet and the liquid crystal panel P, and the bonding sheets F22 and F23, a portion corresponding to the bonding surface of the optical member sheet, and The outer excess part is cut along the outer peripheral edge of the bonding surface, and the optical members F11, F12, and F13 having a size corresponding to the bonding surface are appropriately cut out from the optical member sheet, Cutting devices 16 and 19 for cutting out the single-sided bonding panels P12 and P13 appropriately including the optical members F11, F12, and F13 overlapping the single liquid crystal panel P and the liquid crystal panel P from the bonding sheets F22 and F23.
