As a result, the separator holding unit 19a unwinds the third optical member sheet body F3S in the conveying direction of the third optical member sheet body F3S, and the separator recovery unit 19e becomes a single separator sheet SS via the knife edge 19d. Wind up.

    When the third optical member sheet body F3S is unwound by a predetermined length, the cutting device 19c has a width orthogonal to the longitudinal direction (unwinding direction) of the third optical member sheet body F3S. The separator sheet SS is cut over the entire width in the direction (that is, only the third optical member sheet F3 is cut). The cutting device 19c adjusts the advancing / retreating position of the cutting blade so that the separator sheet SS is not broken by the tension acting during the conveyance of the third optical member sheet body F3S.

In the third optical member sheet body F3S after the cutting, a cut line that extends over the entire width in the width direction of the third optical member sheet body F3S is formed.
Here, in the vicinity of the tip end portion of the knife edge 19d and in the vicinity of the bonding position of the third bonding device 18, the upstream side of the panel conveyance is cut at the downstream side in the unwinding direction of the third optical member F13. A first detection camera 22 for detecting the end is provided. The detection information of the first detection camera 22 is sent to the control device 20. For example, when the first detection camera 22 detects the downstream end of the third optical member F13, the control device 20 temporarily stops the transport device 19. Then, when the 1st detection camera 22 detects the downstream end of the 2nd single-sided bonding panel P12, the control apparatus 20 drives the conveying apparatus 19, and the 2nd single-sided bonding panel P12, the 3rd optical member F13, Can be synchronized and introduced into the bonding position of the third bonding apparatus 18.

    On the other hand, the third optical member F13 is similarly wound on the upstream side in the unwinding direction from the first detection camera 22 and downstream of the cutting device 19c by one third optical member F13 in the unwinding direction. A second detection camera 23 (detection unit) that detects a cut end on the downstream side in the ejection direction is provided. Detection information of the second detection camera 23 is also sent to the control device 20. The control device 20 unwinds the third optical member sheet F3 by the cutting device 19c, for example, and the second detection camera 23 detects the cut end (the cut line on the most upstream side of the third optical member sheet F3). At that time, the conveying device 19 is temporarily stopped. At this time, the third optical member sheet F3 is cut by the cutting device 19c. That is, the detection position by the second detection camera 23 (corresponding to the optical axis extension position of the second detection camera 23 in the third optical member sheet F3) and the cut position by the cutting device 19c (of the cutting device 19c in the third optical member sheet F3). (Corresponding to the cutting blade advance / retreat position) along the sheet conveyance path corresponds to the length of the third optical member F13.

    For example, when the third optical member F13 to be bonded to the liquid crystal panel P of the same size is cut out, the cut lines are formed at equal intervals in the longitudinal direction of the third optical member sheet body F3S. The third optical member sheet F3 is divided into a plurality of sections in the longitudinal direction by a plurality of cut lines, and the sections sandwiched between a pair of cut lines adjacent in the longitudinal direction in the third optical member sheet F3 are respectively third optical members. The member is F13. In the present embodiment, the length of the third optical member F13 is not less than the entire length of the display region P4 and not more than the entire length of the liquid crystal panel P.

    The cutting device 19c is movable along the sheet conveyance path of the third optical member sheet body F3S. By this movement, the distance along the sheet conveyance path between the detection position by the second detection camera 23 and the cutting position by the cutting device 19c varies. The movement of the cutting device 19c is controlled by the control device 20. For example, when the third optical member sheet F3 is unwound by the cutting device 19c after the third optical member sheet F3 is cut, the cut end is moved from a predetermined position. In the case of deviation, this deviation is corrected by the movement of the cutting device 19c.

    It is also possible to cope with the cutting of the third optical member F13 having a different length by the movement of the cutting device 19c. In addition, the correction and the length change of the third optical member F13 may be performed by moving at least one of the cutting device 19c and the second detection camera 23 in the sheet conveyance direction. Further, the cutting device 19c and the second detection camera 23 are close to each other. However, in order to prevent the vibration of the second detection camera 23 accompanying the movement of the cutting device 19c or the like, it is preferable to support them with separate frames.

    The knife edge 19d is disposed below the roller conveyor 5 and extends over at least the entire width in the width direction of the third optical member sheet body F3S. The knife edge 19d is wound at an acute angle so as to be in sliding contact with the separator sheet SS side of the third optical member sheet body F3S after the half cut.

    The third optical member sheet body F3S separates the third optical member F13 from the separator sheet SS when it is folded at an acute angle by the knife edge 19d. The knife edge 19d is disposed close to the panel conveyance downstream side of the pinching roll 21. The third optical member F13 separated from the separator sheet SS by the knife edge 19d is introduced between the pair of bonding rollers of the pinching roll 21 while overlapping the lower surface of the liquid crystal panel P conveyed by the roller conveyor 5.

The pinching roll 21 has a pair of laminating 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 F13 are introduced overlapping each other. These 2nd single-sided bonding panels P12 and the 3rd optical member F13 are sent out to a panel conveyance downstream, being pinched between the said bonding rollers. Thereby, the double-sided bonding panel P13 which bonded the 3rd optical member F13 to the 2nd single-sided bonding panel P12 is formed (refer FIG. 7).

    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 component 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 FIG. 6, 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 other one side of the outer periphery corresponds to the second substrate P2. Bulge outward from one side. 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.

    Referring to FIG. 5, the second cutting device 16 detects the outer peripheral edge of the bonding surface between the laminated body of the second optical member sheet F2 and the sheet piece F1S and the liquid crystal panel P with a detection device described later. Meanwhile, the first and second optical member sheets F1 and F2 are cut along the outer peripheral edge of the bonding surface. FIG. 5 shows an imaging device 43 constituting the detection device. Outside the display region P4, a frame portion G having a predetermined width for arranging a sealant or the like for joining the first and second substrates P1 and P2 is provided. The frame is cut by the second cutting device 16 within the width of the frame portion G. Laser cut is made.

  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. 18 is a schematic diagram of a detection device 41 that detects the outer peripheral edge of the bonding surface. 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 detection device 41 is shown upside down.

  As shown in FIG. 18, the detection apparatus 41 with which the film bonding system 1 of this embodiment is provided is the image of the outer periphery ED of the bonding surface SA of the liquid crystal panel P and the sheet piece F1S in the second bonding sheet F22. An imaging device 43 that captures the image, an illumination light source 44 that illuminates the outer peripheral edge ED, storage of an image captured by the imaging device 43, and a control unit 45 that performs calculations for detecting the outer peripheral edge ED based on the image, Have

  Such a 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 bonding surface SA with respect to the outer peripheral edge ED, and the normal of the bonding surface SA and the normal of the imaging surface 43a of the imaging device 43 are at an angle θ ( Hereinafter, the posture is inclined so as to form 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 bonding surface SA 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 adapted to the distance H between the bonding surface SA 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 as follows. 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. 19 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. 19, for the sake of convenience, the side of the liquid crystal panel P to which the sheet piece F1S is bonded is the upper side, and the configuration of the detection device 41 is shown upside down. As illustrated in FIG. 19, 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 bonding surface SA.

  A distance H1 between the bonding surface SA 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) is set at a position where the outer peripheral edge ED of the bonding surface SA can be easily detected. It is preferred that 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 bonding surface SA rather than the outer periphery ED with respect to the normal line direction of the bonding surface SA. 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. 20 is a plan view showing a position for detecting the outer peripheral edge of the bonding surface. An inspection area CA is set on the conveyance path of the second bonding sheet F22 shown in FIG. The inspection area CA is set at a position corresponding to the outer peripheral edge ED of the bonding surface SA in the transported liquid crystal panel P. In FIG. 20, inspection area | region CA is set to four places corresponding to four corner | angular parts of bonding surface SA of a planar view rectangle, and becomes a structure which detects the corner | angular part of bonding surface SA as outer periphery ED. ing. In FIG. 20, the hook-shaped part corresponding to a corner | angular part is shown as the outer periphery ED among the outer periphery of bonding surface SA.

  18 detects the outer peripheral edge ED in the four inspection areas CA. Specifically, an imaging device 43 and an illumination light source 44 are arranged in each inspection area CA, and the detection device 41 images a corner of the bonding surface SA for each liquid crystal panel P to be transported, 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 bonding surface SA is detectable, the setting position of 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 of each side (for example, center part of each side) of bonding surface SA. In this case, each side (four sides) of the bonding surface SA is detected as an outer peripheral edge.

  Further, 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 set along the outer peripheral edge ED of the bonding surface SA. 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 bonding surface SA. The control unit 45 shown in FIG. 18 has a size that the first optical member F11 does not protrude outside the liquid crystal panel P (outside the bonding surface SA) based on the stored data of the outer peripheral edge ED of the bonding surface SA. Then, the cutting positions of the sheet piece F1S and the second optical member sheet F2 are determined. 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 transport with respect to the detection device 41. The 2nd cutting device 16 is the outer periphery which detected the part corresponding to bonding surface SA among the sheet piece F1S bonded by liquid crystal panel P, and the 2nd optical member sheet | seat F2, and the excess part of the outer side. The first optical member F11 and the second optical member F12 (see FIG. 7) having a size corresponding to the bonding surface SA are cut out along the 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 “part corresponding to the bonding surface SA” means that the outer shape of the liquid crystal panel P (plan view) 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. Is a region that is equal to or less than the size of the contour shape of the liquid crystal panel P and that avoids a functional portion such as an electrical component mounting portion 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.

  As shown in FIG. 9, 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 waved 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. 8, 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.

  When the optical member sheet FX is cut on the liquid crystal panel P, the deflection width (tolerance) of the cutting line of the laser processing machine is smaller than the deflection width of the cutting line of the cutting blade. Therefore, in the present embodiment, it is possible to reduce the width of the frame portion G as compared with the case where the optical member sheet FX is cut using a cutting blade, and the liquid crystal panel P can be reduced in size and / or the display area P4. Can be made larger. 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.

  Here, 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 transported to another line and bonded to the liquid crystal panel P, the dimensional tolerances of the sheet piece and the liquid crystal panel P respectively. In addition, since the dimensional tolerances of these relative bonding positions 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 on the liquid crystal panel P with a laser instead of a blade, the cutting force is not input to the liquid crystal panel P, and cracks and chips are hardly generated at the edge of the substrate of the liquid crystal panel P. Thus, durability against heat cycle and the like 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.

  Moreover, the 3rd bonding apparatus 18 cuts the strip | belt-shaped 3rd optical member sheet | seat F3 which has the width | variety corresponding to the display area P4 to predetermined length, and forms the 3rd optical member F13. The 3rd bonding apparatus 18 is bonded to the 2nd single-sided bonding panel P12 within the line which performs the said cut, conveying this 3rd optical member F13 with separator sheet SS. For this reason, compared with the case where the polarizing plate processed according to the display area P4 is conveyed to another line, the influence of the dimensional variation of the 3rd optical member F13 and bonding variation is suppressed.

  As shown in FIG. 6, when laser cutting the optical member sheet FX (second optical member sheet F2 in FIG. 6), for example, a laser cut start point pt1 is set on the extension of one long side of the display region 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, for a plurality of optical display components PX conveyed on the roller conveyor 5, a strip shape having a width larger than the width of the display region P <b> 4 of the liquid crystal panel P in the component width direction orthogonal to the conveyance direction of the optical display components PX. While the optical member sheets F1 and F2 are unwound from the original fabric rolls R1 and R2, the first optical member sheet F1 and the second optical member sheet F2 and the first surface of the plurality of liquid crystal panels P (one of the front surface and the back surface). In the bonding apparatus 12 and 15 and the 2nd bonding sheet | seat F22 which are bonded together in order and set it as the 2nd bonding sheet | seat F22, for every some liquid crystal panel P, In the detection apparatus 41 which detects the outer periphery ED of the bonding surface SA of the laminated body of the two optical optical member sheet F2 and the sheet piece F1S and the liquid crystal panel P, and the second bonding sheet F22, the second optical member sheet A portion corresponding to the bonding surface SA of the laminate of F2 and the sheet piece F1S and an excessive portion Y outside thereof are separated along the outer peripheral edge ED, and the second optical member sheet F2 and the sheet piece F1S are separated. By cutting out the optical members F11 and F12 having a size corresponding to the bonding surface SA from the laminated body, the single liquid crystal panel P and the optical member F11 overlapping therewith from the second bonding sheet F22, For the 2nd cutting device 16 which cuts out the 2nd single-sided bonding panel P12 containing F12, and the said 2nd single-sided bonding panel P12 conveyed on the roller conveyor 5, the said component A strip-shaped third optical member sheet F3 having a width corresponding to the display area P4 in the direction is unwound together with the separator sheet SS from the third raw roll R3, and the third optical member sheet F3 is moved to the display area P4. Each time the third optical member sheet F3 is unwound by a corresponding length, a cut along the width direction is performed to obtain a third optical member F13 having a size corresponding to the display region P4, and then the separator sheet SS is used as a carrier. The third optical member F13 is transported as the second surface of the liquid crystal panel P in the second single-sided bonding panel P12 (the surface opposite to the first surface, the surface, and the third optical member F13). And a third bonding device 18 for bonding to the other surface of the back surface.

According to this configuration, the third optical member F13 is formed by cutting the band-shaped third optical member sheet F3 having a width corresponding to the display region P4 into a predetermined length. The third optical member F13 is bonded to the liquid crystal panel P in the line for performing the cut while conveying the separator sheet SS unwound together with the optical member sheet F3 as a carrier. For this reason, compared with the case where the polarizing plate processed according to the display region P4 is conveyed to another line, the dimensional variation and the bonding variation of the third optical member F13 are suppressed, and the frame portion G around the display region P4 is reduced. By reducing the size, the display area can be enlarged and the device can be downsized.
Moreover, by combining the cut of the optical member sheets F1 and F2 after bonding to the liquid crystal panel P and the bonding of the third optical member sheet F3 after half-cut leaving the separator sheet SS, Reduction and reduction of tact time can be achieved.

  Further, in the production system for the optical display device, the third bonding device 18 cuts the third optical member sheet F3 together with the separator sheet SS and the third optical member sheet F3. The third optical member F13 in the unwinding direction of the third optical member sheet F3 than the cutting device 19c that forms the third optical member F13 and the cutting position for cutting the third optical member sheet F3. A second detection camera 23 for detecting a cut line formed by the cut on the third optical member sheet F3 at a position spaced downstream by a distance corresponding to one; the downstream from the cut position; When the cut line is detected at a detection position separated by a distance corresponding to one third optical member F13, the cut is performed according to the position of the cut line. And a control unit 20 for adjusting the distance between the detection position and location.

  According to this configuration, the third optical member F13 is unwound in the unwinding direction of the third optical member F13 by the second detection camera 23 that is located downstream from the cutting position of the third optical member sheet F3 by one third optical member F13. When the edge is detected, the third optical member sheet F3 can be cut by the cutting device 19c, and the third optical member F13 having a specified length can be obtained. Even if an error occurs in the unwinding amount of the third optical member sheet F3, the error can be corrected (absorbed) by the relative movement of the cutting device 19c based on the detection information of the second detection camera 23. For this reason, the precision of the length of the 3rd optical member F13 can be ensured, and it can respond also to cutting out of the 3rd optical member F13 from which length differs.

The liquid crystal panel P and the first optical member sheet F1 are overlapped and introduced into the gap. The liquid crystal panel P and the first optical member sheet F1 are sent out to the downstream side of the panel conveyance while being pressed between the bonding rollers. Thereby, the 1st bonding sheet | seat F21 which bonded together the liquid crystal panel P on the lower surface of the elongate 1st optical member sheet | seat F1 at predetermined intervals is formed.

    The 1st cutting device 113 is located in a panel conveyance downstream rather than pf collection | recovery part 112d. 4 and 5 together, the first cutting device 113 cuts the first optical member sheet F1 of the first bonding sheet F21 and is larger than the display area P4 (in this embodiment, from the liquid crystal panel P).

By the said cutting | disconnection, the 1st single-sided bonding panel P11 by which the said sheet piece F1S larger than the display area P4 was bonded on the upper surface of liquid crystal panel P is formed.

  In the sheet piece F1S, the size of the portion that protrudes outside the liquid crystal panel P (the size of the surplus portion of the sheet piece F1S) is appropriately set according to the size of the liquid crystal panel P. For example, when the sheet piece F1S is applied to a medium-sized liquid crystal panel P of 5 to 10 inches, the distance between one side of the sheet piece F1S and one side of the liquid crystal panel P is 2 mm on each side of the sheet piece F1S. Set to a length in the range of ~ 5 mm.

    Referring to FIG. 13, for example, the second alignment device 114 holds the first single-sided bonding panel P11 on the roller conveyor 105 and rotates it by 90 ° around the vertical axis. Thereby, the first single-sided bonding panel P11 that has been transported substantially parallel to the short side of the display region P4 changes direction so as to be transported substantially parallel to the long side of the display region P4. In addition, the said rotation is made | formed when the optical axis direction of the other optical member sheet | seat bonded to liquid crystal panel P is arrange | positioned at right angle with respect to the optical axis direction of the 1st optical member sheet | seat F1.

    The second alignment device 114 performs the same alignment as the first alignment device 111. That is, the second alignment device 114 is based on the inspection data in the optical axis direction stored in the control device 120 and the imaging data of the camera C, and the component width direction of the first single-sided bonding panel P11 with respect to the second bonding device 115. And positioning in the rotation direction. In this state, the first single-sided bonding panel P11 is introduced into the bonding position of the second bonding device 115.

    The 2nd bonding apparatus 115 is the upper surface (of liquid crystal panel P of the 1st single-sided bonding panel P11 conveyed below the lower surface of the elongate 2nd optical member sheet | seat F2 introduce | transduced into the bonding position. Paste the backlight side. That is, in the 1st single-sided bonding panel P11, the 1st single-sided bonding panel P11 and the 1st single-sided bonding panel P11 so that the sheet piece F1S bonded to the backlight side of liquid crystal panel P and the 2nd optical member sheet | seat F2 may contact.

And a second recovery part 115d that recovers an excess portion of the second optical member sheet F2 that has passed through the second cutting device 116 located on the downstream side of the panel conveyance from the pinching roll 115b. The conveying device 115a is a bonding position in the second bonding device 115, and the second optical member sheet so that the bonding surface of the second optical member sheet F2 bonded to the first single-sided bonding panel P11 faces downward. The conveyance path of F2 is set.

    The pinching roll 115b has a pair of laminating rollers arranged in parallel with each other in the axial direction. A predetermined gap is formed between the pair of bonding rollers, and the gap is the bonding position of the second bonding apparatus 115. The first single-sided bonding panel P11 and the second optical member sheet F2 are overlapped and introduced into the gap. These 1st single-sided bonding panels P11 and the 2nd optical member sheet | seat F2 are sent out to a panel conveyance downstream, being pinched between the said bonding rollers. Thereby, the 2nd bonding sheet | seat F22 which bonded the several 1st single-sided bonding panel P11 continuously on the lower surface of the elongate 2nd optical member sheet | seat F2 is formed, keeping predetermined space | interval.

    The 2nd cutting device 116 is located in the panel conveyance downstream rather than the pinching roll 115b. 14 and 5 together, the second cutting device 116 includes the second optical member sheet F2 and the sheet piece F1S of the first optical member sheet F1 of the first single-sided bonding panel P11 bonded to the lower surface thereof. Disconnect at the same time. The second cutting device 116 has the same configuration as the second cutting device 16 of the first embodiment. By using the second cutting device 116, the accuracy in the optical axis direction of each of the optical member sheets F1 and F2 is increased, the displacement in the optical axis direction between the optical member sheets F1 and F2 is eliminated, and the first cutting device 113 is used. The cutting at is simplified.

    By the cutting | disconnection of the 2nd cutting device 116, the 1st and 2nd optical member F11, F12 overlapped and bonded on the upper surface of liquid crystal panel P (refer FIG. 7), and the 2nd single-sided bonding panel P12 is formed. Moreover, the 2nd single-sided bonding panel P12 and the part (each optical member F11, F12) corresponding to the bonding surface are cut off, and the excess part of each optical member sheet | seat F1, F2 which remains in frame shape is isolate | separated. The A plurality of surplus portions of the second optical member sheet F2 are connected in a ladder shape (see FIG. 14), and the surplus portions are wound around the second collection portion 115d together with the surplus portions of the first optical member sheet F1.

    Referring to FIG. 13, the third alignment device 117 reverses the surface and the back surface of the second single-sided bonding panel P12 with the backlight side of the liquid crystal panel P as the upper surface, and the display surface side of the liquid crystal panel P as the upper surface. At the same time, alignment similar to that of the first and second alignment devices 111 and 114 is performed. That is, the third alignment device 117 is based on the inspection data in the optical axis direction stored in the control device 120 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 118. And positioning in the rotation direction. In this state, the second single-sided bonding panel P12 is introduced into the bonding position of the third bonding device 118.

    As shown in FIG.13 and FIG.16, the 3rd bonding apparatus 118 is the 3rd optical member sheet | seat F3 and separator from the 3rd original fabric roll R3 which wound the 3rd optical member sheet | seat F3 with separator sheet SS which overlaps this. A transport device 119 that transports the sheet SS while unwinding and feeds the third optical member F13 from the third optical member sheet F3 to the bonding position, and a third transport device 119 cuts out from the third optical member sheet F3. The pressure roller 121 is bonded to the upper surface (the display surface side of the liquid crystal panel P) of the second single-sided bonding panel P12 that the roller conveyor 105 conveys the lower surface of the optical member F13.

    The transport device 119 continuously transports the plurality of third optical members F13 using the separator sheet SS as a carrier, similarly to the transport device 19 of the first embodiment. The transport device 119 holds the third original fabric roll R3 and rolls out the third optical member sheet F3S from the third original fabric roll R3 along the longitudinal direction of the third optical member sheet F3S. 119a (unwinding part) and the third optical member sheet F3S unwound from the third original fabric roll R3 are guided to the bonding position of the third bonding apparatus 118 along the predetermined sheet conveying path. Single or plural (only one is shown in the figure) guide rollers 119b for winding the separator sheet SS side of the optical member sheet body F3S, and a half that leaves the separator sheet SS on the third optical member sheet body F3S on the sheet conveyance path A cutting device 119c (cut portion) that performs cutting and a separator sheet SS side of the third optical member sheet F3S that has been half-cut are wound around an acute angle to set the A knife edge 119d for supplying the third optical member F13 to the bonding position while separating the third optical member F13 from the separator sheet SS, and a separator collecting unit 119e for winding up the separator sheet SS that has become independent through the knife edge 119d; Have

    The roll holding unit 119a positioned at the start point of the transport device 119 and the separator collection unit 119e positioned at the end point of the transport device 119 are driven in synchronization with each other, for example. As a result, the separator holding unit 119e unwinds the third optical member sheet body F3S in the conveying direction of the third optical member sheet body F3S, and the separator recovery unit 119e becomes a single separator sheet SS via the knife edge 119d. Wind up.

    When the third optical member sheet body F3S is unwound by a predetermined length, the cutting device 119c has a width orthogonal to the longitudinal direction (unwinding direction) of the third optical member sheet body F3S. The separator sheet SS is cut over the entire width in the direction (that is, only the third optical member sheet F3 is cut). The cutting device 119c adjusts the advancing / retreating position of the cutting blade so that the separator sheet SS is not broken by the tension acting during the conveyance of the third optical member sheet body F3S.

In the third optical member sheet body F3S after the cutting, a cut line that extends over the entire width in the width direction of the third optical member sheet body F3S is formed.
Here, in the vicinity of the front end of the knife edge 119d and in the vicinity of the bonding position of the third bonding apparatus 118, the upstream side of the panel conveyance is cut downstream in the unwinding direction of the third optical member F13 at the position. A first detection camera 122 for detecting the end is provided. Detection information of the first detection camera 122 is sent to the control device 120. For example, when the first detection camera 122 detects the downstream end of the third optical member F13, the control device 120 temporarily stops the transport device 119.
Then, when the 1st detection camera 122 detects the downstream end of the 2nd single-sided bonding panel P12, the control apparatus 120 drives the conveying apparatus 119, 2nd single-sided bonding panel P12, the 3rd optical member F13, Can be synchronized and introduced into the bonding position of the third bonding apparatus 118.

On the other hand, the third optical member F13 is similarly wound on the upstream side of the first detection camera 122 in the unwinding direction and downstream of the cutting device 119c by one third optical member F13. A second detection camera 123 that detects a cut end on the downstream side in the ejection direction is provided.
Detection information of the second detection camera 123 is also sent to the control device 120. For example, after the third optical member sheet F3 is cut by the cutting device 119c, the control device 120 unwinds the third optical member sheet F3, and the second detection camera 123 detects the cut end (the cut line on the most upstream side of the third optical member sheet F3). At this point, the transfer device 119 is temporarily stopped. At this time, the third optical member sheet F3 is cut by the cutting device 119c. That is, the detection position by the second detection camera 123 (corresponding to the optical axis extension position of the second detection camera 123 in the third optical member sheet F3) and the cut position by the cutting device 119c (of the cutting device 119c in the third optical member sheet F3). (Corresponding to the cutting blade advance / retreat position) along the sheet conveyance path corresponds to the length of the third optical member F13.

    The cutting device 119c is movable along the sheet conveyance path of the third optical member sheet body F3S. By this movement, the distance along the sheet conveyance path between the detection position by the second detection camera 123 and the cutting position by the cutting device 119c varies. The movement of the cutting device 119c is controlled by the control device 120. For example, when the third optical member sheet F3 is unwound by one piece after the third optical member sheet F3 is cut by the cutting device 119c, the cut end is moved from a predetermined position. In the case of deviation, this deviation is corrected by the movement of the cutting device 119c.

    Note that it is possible to cope with the cutting of the third optical member F13 having a different length by the movement of the cutting device 119c. In addition, the correction or the length change of the third optical member F13 may be performed by moving at least one of the cutting device 119c and the second detection camera 123 in the sheet conveyance direction. Moreover, although the cutting device 119c and the second detection camera 123 are close to each other, in order to prevent vibration of the second detection camera 123 accompanying the movement of the cutting device 119c, it is preferable to support them with separate frames.

    The knife edge 119d is disposed above the roller conveyor 105 and extends at least over the entire width in the width direction of the third optical member sheet body F3S. The knife edge 119d is wound at an acute angle so as to be in sliding contact with the separator sheet SS side of the third optical member sheet body F3S after the half cut.

    The third optical member sheet body F3S separates the third optical member F13 from the separator sheet SS when it is folded at an acute angle by the knife edge 119d. The knife edge 119d is disposed close to the panel conveyance downstream side of the pinching roll 121. The third optical member F13 separated from the separator sheet SS by the knife edge 119d is introduced between the pair of bonding rollers of the pinching roll 121 while overlapping the upper surface of the liquid crystal panel P conveyed by the roller conveyor 105.

    The pinching roll 121 has a pair of laminating rollers arranged with their axial directions parallel to each other. A predetermined gap is formed between the pair of bonding rollers, and the inside of this gap is the bonding position of the third bonding device 118. In the gap, the second single-sided bonding panel P12 and the third optical member F13 are introduced overlapping each other. These 2nd single-sided bonding panels P12 and the 3rd optical member F13 are sent out to a panel conveyance downstream, being pinched between the said bonding rollers. Thereby, the double-sided bonding panel P13 which bonded the 3rd optical member F13 to the 2nd single-sided bonding panel P12 is formed (refer FIG. 7).

    Similar to the transport device 19 of the first embodiment, the double-sided bonding panel P13 is transported to a downstream process after being inspected for defects (such as poor bonding) through a defect inspection device (not shown). Processing is done.

    Similarly to the control device 20 of the first embodiment described above, 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 device is each optical member sheet. The data are stored in the memory of the control device 120 in association with the longitudinal position and the width direction position of F1, F2, and F3. Moreover, similarly to 1st embodiment mentioned above, each optical member sheet | seat F1, F2, F3 is wound up after test | inspection, and each original fabric roll R1, R2, R3 is formed, respectively.

    In the present embodiment, similar to the control device 20 of the first 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 120, the optical display to be bonded to them. After aligning the component PX, the optical display component PX is bonded to the optical member sheet FX. Thereby, the same effect as the first embodiment can be obtained.

    FIG. 15 shows an example in which three optical display components PX are aligned and bonded to a relatively wide optical member sheet FX in the width direction. However, the present invention is not limited thereto, and two or less or four or more optical displays are displayed. It is a configuration in which the parts PX are arranged and bonded in the width direction of the optical member sheet FX, or a plurality of relatively narrow optical member sheets FX are arranged in the width direction and the optical display components PX are bonded to each of them. May be.

Referring to FIG. 5, the second cutting device 116 is along the outer peripheral edge ED (see FIG. 20) of the bonding surface SA of the laminated body of the second optical member sheet F2 and the sheet piece F1S and the liquid crystal panel P. Then, the first and second optical member sheets F1 and F2 are cut. Outside the display area P4, a frame portion G having a predetermined width for arranging a sealant or the like for bonding the first and second substrates P1 and P2 is provided. The frame is cut by the second cutting device 116 within the width of the frame portion G. Laser cut is made.
By using such a cutting device, the same effect as the first embodiment can be obtained (see FIGS. 8 and 9).

  Moreover, in the 3rd bonding apparatus 118, the strip | belt-shaped 3rd optical member sheet | seat F3 which has a width | variety corresponding to the display area P4 is cut into predetermined length, and the 3rd optical member F13 is formed. The 3rd bonding apparatus 118 is bonded to the 2nd single-sided bonding panel P12 within the line which performs the said cut, conveying this 3rd optical member F13 with separator sheet SS. For this reason, compared with the case where the polarizing plate processed according to the display area P4 is conveyed to another line, the influence of the dimensional variation of the 3rd optical member F13 and bonding variation is suppressed.

  As shown in FIG. 6, when laser cutting the optical member sheet FX (second optical member sheet F2 in FIG. 6), for example, a laser cut start point pt1 is set on the extension of one long side of the display region 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. 101, a plurality of optical display components PX conveyed on the roller conveyor 105 have a strip shape having a width larger than the width of the display area P4 of the liquid crystal panel P in the component width direction orthogonal to the conveyance direction of the optical display components PX. The optical member sheets F1 and F2 are unwound from the original rolls R1 and R2, and the second optical member sheet F2 and the first surfaces of the plurality of liquid crystal panels P are sequentially bonded to the first optical member sheet F1. In the bonding apparatus 112,115 used as the bonding sheet F22 and the second bonding sheet F22, for each of the plurality of liquid crystal panels P, the second optical optical member sheet is used. The second optical member sheet F2 and the sheet piece in the detection device 41 for detecting the outer peripheral edge ED of the bonding surface SA of the laminated body of the core F2 and the sheet piece F1S and the liquid crystal panel P, and the second bonding sheet F22. From the laminate of the second optical member sheet F2 and the sheet piece F1S, the portion corresponding to the bonding surface SA of the laminate with F1S and the excess portion Y outside thereof are cut along the outer peripheral edge ED. By cutting out the optical members F11 and F12 having a size corresponding to the bonding surface SA, the first liquid crystal panel P and the optical members F11 and F12 that overlap the single liquid crystal panel P from the second bonding sheet F22.

A strip-shaped third optical member sheet F3 having a width corresponding to the display region P4 is unwound together with the separator sheet SS from the third raw roll R3, and the third optical member sheet F3 has a length corresponding to the display region P4. Now, every time the third optical member sheet F3 is unwound, it is cut along the width direction to form a third optical member F13 having a size corresponding to the display region P4, and then a plurality of separator sheets SS are used as carriers. A third bonding device 118 for bonding the third optical member F13 to the second surface of the liquid crystal panel P in the second single-sided bonding panel P12 while conveying the third optical member F13; At the bonding position between the member sheets F1 and F2 and the optical display component PX, the bonding surfaces of the optical member sheets F1 and F2 bonded to the optical display component PX face downward.

The third bonding device 118 conveys the third optical member sheet F3 such that the bonding surface of the member sheet F3 with the second single-sided bonding panel P12 faces downward.

According to this configuration, the third optical member F13 is formed by cutting the band-shaped third optical member sheet F3 having a width corresponding to the display region P4 into a predetermined length. The third optical member sheet F3 is bonded to the liquid crystal panel P in the line for performing the cutting while the separator sheet SS unwound together with the optical member sheet F3 is conveyed as a carrier.
For this reason, compared with the case where the polarizing plate processed according to the display region P4 is conveyed to another line, the dimensional variation and the bonding variation of the third optical member F13 are suppressed, and the frame portion G around the display region P4 is reduced. By reducing the size, the display area can be enlarged and the device can be downsized.

Thereby, since the optical member of a desired size can be cut off regardless of the individual difference in the size of the liquid crystal panel P or the laminate, the quality variation due to the individual difference in the size of the liquid crystal panel P or the laminate is eliminated. The frame portion around the display area can be reduced to enlarge the display area and downsize the device.

  The optical display device production system includes the third alignment device 117 that reverses the front and back surfaces of the second single-sided bonding panel P12 conveyed on the roller conveyor 105, so that the optical display component PX The optical member sheet FX can be easily bonded to both the front surface and the back surface from above.

According to the position of the cut line when the cut line is detected at a detection position separated by a distance corresponding to one third optical member F13. And a control unit 120 for adjusting the distance between the detection position and the cutting position.

  According to this configuration, the third optical member F13 is unwound in the unwinding direction of the third optical member F13 by the second detection camera 123 that is located downstream from the cutting position of the third optical member sheet F3 by one third optical member F13. When the end is detected, the third optical member sheet F3 can be cut by the cutting device 119c, and the third optical member F13 having a specified length can be obtained. Even if an error occurs in the unwinding amount of the third optical member sheet F3, the error can be corrected (absorbed) by the relative movement of the cutting device 119c based on the detection information of the second detection camera 123. For this reason, the precision of the length of the 3rd optical member F13 can be ensured, and it can respond also to cutting out of the 3rd optical member F13 from which length differs.

  Here, the production method of the optical display device in the above embodiment is such that the liquid crystal panel P is aligned in the component width direction orthogonal to the conveyance direction of the optical display component PX with respect to the plurality of optical display components PX conveyed on the roller conveyor 105.
