A fitting device 13. In the present embodiment, the third transport device 61 is not accompanied by an operation of swirling the liquid crystal panel P when the liquid crystal panel P is transported. In other words, in the secondary conveyor 7, the liquid crystal panel P that has been transported in the direction in which the long side of the display region P4 is transported is conveyed to the first bonding apparatus 13 (the bonding stage 41 (refer to the fifth FIG.)) is also formed to maintain the direction in which the long side is along the transport direction.

The liquid crystal panel P performs the first optical component F11 by the first bonding device 13 The fit on the display side. The first bonding apparatus 13 sets the first width corresponding to the short side of the display area P4 so that one end side of the short side of the display area P4 faces the other end side or the other end side toward the one end side.

The liquid crystal panel P performs peeling of the surface protective film F4a of the first optical member F11 in the first film peeling device 21.

The liquid crystal panel P on which the surface protective film F4a has been peeled off is carried by the third transfer device 61 to the first bonding position 7b of the secondary conveyor 7. At this time, the third conveying device 61 reverses the front and back of the liquid crystal panel P, releases the suction at the first bonding position 7b, and delivers the liquid crystal panel P to the secondary conveyor 7. However, the third transport device 61 reverses the front and back of the liquid crystal panel P, but does not perform the operation of swirling the liquid crystal panel P.

The situation in the direction of the transport direction.

The fourth transfer device 62 holds the liquid crystal panel P and transports it freely in the vertical direction and the horizontal direction. For example, the fourth transfer device 62 transports the liquid crystal panel P held by the adsorption in a horizontal state by the second bonding position 7c of the secondary conveyor 7, and releases the liquid crystal panel P to the second by releasing the adsorption. Bonding device 15.

In the present embodiment, the fourth transport device 62 is not accompanied by an operation of swirling the liquid crystal panel P when the liquid crystal panel P is transported. In other words, in the secondary conveyor 7, the liquid crystal panel P that has been transported in the direction in which the long side of the display region P4 is transported in the direction of the transport direction is formed so as to hold the long side along the aforementioned The direction of the transport direction.

In the liquid crystal panel P, the second optical member F12 is bonded to the backlight side by the second bonding apparatus 15.

The second bonding apparatus 15 has a wide width corresponding to the long side of the display region P4 so that one end side of the display region P4 faces the other end side or the other end side faces one end side. The two optical members F12 are attached to the backlight side of the liquid crystal panel P. That is, the second bonding apparatus 15 constitutes the other side bonding apparatus described in the patent application.

The liquid crystal panel P to which the second optical member F12 is bonded is carried by the second bonding device 15 to the second film peeling device 22 by the fourth transfer device 62. The liquid crystal panel P is attached to the second film peeling device 22, and the surface protective film F4a of the second optical member F12 is peeled off.

The liquid crystal panel P on which the surface protective film F4a has been peeled off is carried by the fourth transfer device 62 to the second bonding position 7c of the secondary conveyor 7. At this time, since the fourth conveyance device 62 does not perform the operation of rotating the liquid crystal panel P, the liquid crystal panel P is also formed to maintain the direction of the long side along the conveyance direction after being transferred to the second bonding position 7c again.

The fifth transport device 63 holds the liquid crystal panel P and transports it freely in the vertical direction and the horizontal direction. The fifth transporting device 63 transports the liquid crystal panel P held by the suction to the third bonding position 7d of the secondary conveyor 7 while being horizontally held, and releases the liquid crystal panel P to the third by releasing the adsorption. Bonding device 18.

In the present embodiment, the fifth transport device 63 is not accompanied by an operation of swirling the liquid crystal panel P when the liquid crystal panel P is transported. In other words, in the secondary conveyor 7, the liquid crystal panel P that has been transported in the direction in which the long side of the display region P4 is transported in the direction of the transport direction is formed so as to hold the long side along the aforementioned The direction of the transport direction.

The liquid crystal panel P is bonded to the third optical member F13 on the backlight side by the third bonding apparatus 18.

The third bonding device 18 is oriented from one end side of the long side of the display area P4 The wide third optical member F13 corresponding to the long side of the display region P4 is bonded to the backlight side of the liquid crystal panel P so that the other end side or the other end side faces the one end side. That is, the third bonding apparatus 18 constitutes the other side bonding apparatus described in the patent application. That is, in the present embodiment, the second bonding device 15 and the third bonding device 18 are provided as the other surface side bonding device.

The liquid crystal panel P to which the third optical member F13 is bonded is carried by the third bonding device 18 to the third film peeling device 23 by the fifth transfer device 63. The liquid crystal panel P is attached to the third film peeling device 23, and the surface protective film F4a of the third optical member F13 is peeled off.

The liquid crystal panel P on which the surface protective film F4a has been peeled off is carried into the third bonding position 7d of the secondary conveyor 7 by the fifth conveying device 63. At this time, since the fifth conveyance device 63 does not perform the operation of rotating the liquid crystal panel P, the liquid crystal panel P also maintains the direction in which the long side is along the conveyance direction after being transferred to the third bonding position 7d again.

The secondary conveyor 7 is a position on the downstream side in the conveyance direction of the third bonding position 7d as a bonding inspection position 7e (refer to FIG. 5). At the bonding inspection position 7e, inspection of the workpiece (liquid crystal panel P) to which the film has been bonded is inspected by the inspection device 19 (whether the position of the optical member F1X is appropriate (whether the positional deviation is within the tolerance range) or the like ). The workpiece that is determined to be not suitable for the position of the optical member F1X with respect to the liquid crystal panel P is discharged to the outside of the system by a discarding means (not shown).

The secondary conveyor 7 sets the position on the downstream side in the conveyance direction of the bonding inspection position 7e as the end position 7f (refer FIG. 5). At the end position 7f, the liquid crystal panel P is carried out by the second conveyance device 9 for the carry-out conveyor 6.

The second conveying device 9 holds the liquid crystal panel P held by, for example, adsorption. In the horizontal state, the substrate carrying-out position 6a is conveyed to the carry-out conveyor 6, and the suction is released at this position, and the liquid crystal panel P is transferred to the carry-out conveyor 6. The bonding process by the film bonding system 1 is completed above.

The first bonding device 13 will be described in detail below with reference to the sixth and seventh drawings. The sixth drawing is a schematic side view of the first bonding apparatus 13. The second bonding device 15 and the third bonding device 18 have the same configuration, and detailed description thereof will be omitted.

The first bonding apparatus 13 performs bonding of the sheet piece (first optical member F11) of the bonding sheet F5 cut into a predetermined size in the first optical member sheet F1 on the upper surface of the liquid crystal panel P.

As shown in FIG. 6, the first bonding apparatus 13 is provided with a first optical component sheet while unwinding the first optical component sheet F1 by the material roll R1 around which the first optical component sheet F1 is wound. The sheet conveying device 31 that conveys the material F1 along the longitudinal direction thereof; and the sheet conveying device 31 holds the sheet piece of the bonding sheet F5 cut out by the first optical member sheet F1 (the first optical member F11) And the sheet piece is bonded to the bonding part 40 of the upper surface of the liquid crystal panel P.

In the sheet conveying device 31, the separator sheet F3a is used as a carrier to convey the bonding sheet F5, and has a raw material roll R1 in which the strip-shaped first optical member sheet F1 is wound, and the first optical member sheet is held. a unwinding portion 31a that is fed along its longitudinal direction; a cutting device 31b that performs half-cutting on the first optical member sheet F1 unwound by the raw material roll R1; and a first optical member that has been subjected to half-cutting When the sheet F1 is bonded to the sheet F5, the knife edge 31c of the spacer sheet F3a is pressed upward; the winding portion 31d of the spacer roll R2 around which the spacer sheet F3a is wound; and the support The lower sheet stage 33 of the first optical member sheet F1.

The sheet conveying device 31 has a winding along a predetermined conveying path The plurality of guide rollers GR1, GR2, GR3 of the first optical member sheet F1; and the pressing roller GR4. The first optical member sheet F1 has a width in a horizontal direction (sheet width direction) orthogonal to the conveyance direction, and has a width corresponding to the display region P4 of the liquid crystal panel P (in the present embodiment, it corresponds to the display region P4). The length of the short side is equal to the width.

The unwinding unit 31a located at the starting point of the sheet conveying device 31 and the winding unit 31d located at the end of the sheet conveying device 31 are driven in synchronization with each other, for example. Thereby, the unwinding unit 31a feeds the separator sheet F3a passing through the blade 31c by the winding unit 31d while feeding the first optical member sheet F1 in the conveyance direction. Hereinafter, the upstream side in the conveyance direction of the first optical member sheet F1 (the separator sheet F3a) in the sheet conveying device 31 is referred to as the sheet conveyance upstream side and the conveyance direction downstream side is referred to as a sheet conveyance downstream side.

The cutting device 31b is each longer in the longitudinal direction orthogonal to the sheet width direction of the first optical member sheet F1, and corresponds to the length of the display region P4 (in the present embodiment, it corresponds to the length of the display region P4). When the side length is sent in the same length, that is, a part of the thickness direction of the first optical member sheet F1 is cut (half-cut) over the entire width along the sheet width direction.

The cutting device 31b is a method in which the first optical member sheet F1 (the separator sheet F3a) is not broken by the tension applied during the conveyance of the first optical member sheet F1 (remaining in a predetermined thickness) In the manner of the spacer sheet F3a, the advance and retreat positions of the cutting edge are adjusted, and the half cut is performed until the interface between the adhesive layer F2a and the spacer sheet F3a. Among them, a laser device that replaces the cutting blade can also be used.

The first optical member sheet F1 after the half-cut is cut in the thickness direction thereof by the optical member body F1a and the surface protective film F4a, thereby forming the first optical member sheet F1. The full-width cut line of the sheet in the wide direction. The first optical member sheet F1 is divided into a section having a length corresponding to the length of the long side of the display region P4 by the slit line in the longitudinal direction. This division becomes one sheet piece (first optical member F11) of the bonding sheet F5, respectively.

The blade 31c is located above the first optical member sheet F1 which is conveyed substantially horizontally from the left side to the right side of the sixth drawing, and extends at least over the entire width of the first optical member sheet F1 in the sheet width direction. The blade 31c can advance and retreat along the conveying direction of the first optical member sheet F1, and presses the upper side of the spacer sheet F3a separated by the half-cut first optical member sheet F1.

The bonding unit 40 includes a bonding stage 41 that holds the liquid crystal panel P at the time of bonding, a bonding cylinder 32, and a driving device 42 that drives the bonding cylinder 32 to rotate or move. The driving device 42 is electrically connected to the control device 25, and the driving device 42 can control the driving of the driving device 42.

The bonding stage 41 is for holding the liquid crystal panel P to which the bonding sheet F5 is bonded. The bonding stage 41 holds the liquid crystal panel P by, for example, adsorption.

The bonding cylinder 32 has a cylindrical holding surface 32a that is parallel to the sheet width direction. The holding surface 32a has, for example, a weaker adhesion force than the bonding surface (adhesive layer F2a) of the bonding sheet F5, and the surface protective film F4a of the bonding sheet F5 can be attached and peeled off.

The seventh drawing is a view for explaining the attaching action of the bonded sheet F5 to the bonding cylinder 32.

The unwinding unit 31a and the winding unit 31d temporarily stop the driving at the timing when the end portion 31e of the sheet conveying downstream side of the sheet F5 reaches the standby position of the bonding cylinder 32.

The driving device 42 is as shown in FIG. 7A, and if the sheet of the bonded sheet F5 is conveyed, When the end portion 31e on the side of the swim reaches the lower side of the bonding cylinder 32, the bonding cylinder 32 is lowered by a predetermined amount. Thereby, the bonding cylinder 32 holding surface 32a is in contact with the bonding sheet F5, and the edge part 31e of the bonding sheet F5 is adhered to the holding surface 32a.

In the present embodiment, the first detection camera 34 that detects the leading end of the sheet conveyance downstream side of the sheet piece of the bonded sheet F5 in the portion is provided below the tip end portion of the blade 31c. The first detecting camera 34 images the end portion 31e of the bonded sheet F5 through the through hole 33a provided in the sheet stage 33. The detection information of the first detecting camera 34 is sent to the control device 25. The control device 25 temporarily stops the sheet conveying device 31 when, for example, the first detecting camera 34 detects the end portion 31e.

When the first detecting camera 34 detects the downstream end of the bonded sheet F5 and temporarily stops the sheet conveying device 31, the control device 25 performs cutting of the bonded sheet F5 by the cutting device 31b. That is, along the detection position obtained by the first detection camera 34 (the optical axis extension position of the first detection camera 34) and the cutting position obtained by the cutting device 31b (the cutting edge of the cutting device 31b advances and retreats) The distance of the sheet conveyance path between the positions is equivalent to the length of the sheet piece to which the sheet F5 is bonded.

The cutting device 31b is movable along the sheet conveying path by which the sheet conveyance between the detection position obtained by the first detecting camera 34 and the cutting position obtained by the cutting device 31b is carried out. The distance of the path will change. The movement of the cutting device 31b is controlled by the control device 25. For example, after the cutting of the bonded sheet F5 by the cutting device 31b, the sheet of the sheet F5 is unwound one by one. At this time, if the cut end is shifted by the predetermined reference position, the offset is corrected by the movement of the cutting device 31b. However, it is also possible to correspond to the cutting of the bonded sheet F5 having a different length by the movement of the cutting device 31b.

The first detecting camera 34 also detects the defective mark printed on the bonded sheet F5. The aforementioned defect mark is a defect portion found in the first optical member sheet F1 at the time of manufacture of the raw material roll R1, and is marked by inkjet or the like from the side of the surface protective film F4a.

Here, the disadvantage of the optical member sheet FX is that, for example, a portion of a foreign matter formed of at least one of a solid, a liquid, and a gas exists inside the optical member sheet FX, or exists on the surface of the optical member sheet FX. A portion that is uneven or damaged, a portion that becomes a bright spot due to deformation of the optical member sheet FX, or a bias of a material.

In the above, the bonded sheet F5 in which the defective mark is detected is attached to the bonding cylinder 32, and is not attached to the liquid crystal panel P to move to the disposal position (discarded position) avoiding the bonding stage 41. ) and stacked on scrap sheets and the like. Alternatively, the step of discarding the bonded sheet F5 with a minimum width when the defective mark is detected may be used.

After the bonded sheet F5 is cut, the driving device 42 is rotated in the direction (counterclockwise rotation direction) of the bonded sheet F5 that is wound and adhered to the holding surface 32a as shown in FIG. The cylinder 32 moves along the transport upstream side (the left direction in the seventh B diagram). As described above, the bonding sheet 32 is rotated while the bonding sheet F5 is being fed, whereby the entire sheet sheet to which the sheet F5 is bonded is attached to the holding surface 32a.

Here, the winding portion 31d (see FIG. 6) is a method in which the spacer sheet F3a is not broken when the bonded sheet F5 is attached to the bonding cylinder 32, and the bonding cylinder 32 is attached. The drive is synchronously driven to rotate in a direction in which the spacer sheet F3a is unwound (counterclockwise rotation). The separator sheet F3a is formed in a state of being released from the upstream side of the conveyance. The bonding cylinder 32 continues the above-described rotation and movement in order to wind up the bonding sheet F5 adhered to the holding surface 32a. Thereby, the bonding sheet F5 is attached to the portion to be bonded to the bonding cylinder 32 (holding surface 32a) (end) The near portion of the portion 31e) is loosened, and is formed in a state of having a curved portion F3a1 that is curved upward toward the sheet stage 33.

In order to prevent the spacer sheet F3a from floating up, the blade edge 31c is brought closer to the bonding cylinder 32 side from the standby position in synchronization with the timing of unwinding the spacer sheet F3a, as shown in FIG. The portion abuts against the spacer sheet F3a.

The winding portion 31d is rotationally driven in the direction (clockwise rotation) of the winding separator sheet F3a at the timing when the tip end portion of the blade 31c abuts against the spacer sheet F3a. At this time, the bonding cylinder 32 continues the above-described rotation and movement in order to wind up the bonding sheet F5 adhered to the holding surface 32a.

Thereby, the bonding sheet F5 is wound up along the circumferential direction of the holding surface 32a of the bonding cylinder 32. While the bonded sheet F5 is wound by the bonding cylinder 32, the separator sheet F3a is wound by the winding portion 31d. At this time, the spacer sheet F3a is formed in a state of being pressed upward by the blade 31c.

Thereby, a force for peeling off both of the bonded sheet F5 and the separator sheet F3a is generated, and the separator sheet F3a can be peeled off from the bonded sheet F5. The curved portion F3a1 gradually becomes smaller and eventually disappears. In this manner, the surface protective film F4a (the surface opposite to the bonding surface) of the sheet piece of the bonded sheet F5 is sequentially attached to the holding surface 32a of the bonding cylinder 32. At this time, the adhesive layer F2a (the bonding surface with the liquid crystal panel P) of the bonding sheet F5 is a downward direction.

The driving device 42 is driven by rotating the bonding cylinder 32 by a predetermined amount until the portion where the slit line is formed is attached to the holding surface 32a, and as shown in FIG. 7D, the bonding cylinder 32 is moved upward. the amount. At this time, the sheet conveying device 31 stops the feeding operation of the spacer sheet F3a. Further, the blade 31c is returned to the aforementioned standby position.

The bonded sheet F5 moves to the upper side together with the bonding cylinder 32 in accordance with the movement of the bonding cylinder 32. At this time, the bonding sheet F5 is formed in a state in which it is completely separated by the separator sheet F3a and is bonded to the holding surface 32a. The bonding cylinder 32 to which the bonding sheet F5 is attached to the holding surface 32a is moved to the bonding stage 41, and the bonding sheet F5 attached to the bonding cylinder 32 is attached as will be described later. In the liquid crystal panel P.

In the present embodiment, when the bonding cylinder 32 to which the bonding sheet F5 is attached is moved by the sheet stage 33 to the bonding stage 41, the bonding sheet attached to the holding surface 32a is attached. The four corner portions of F5 are respectively imaged by the second detecting camera 35 as an imaging device. The detection information of each of the second detecting cameras 35 is sent to the control device 25. The control device 25 confirms the arrangement position of the bonded sheet F5 with respect to the bonding cylinder 32 based on, for example, the image data of each of the second detecting cameras 35. The control device 25 causes the bonding stage 41 to be aligned in the direction orthogonal to the rotation axis of the bonding cylinder 32 by the driving device (not shown) based on the imaging data of each of the second detecting cameras 35. The rotation axes of the cylinders 32 are respectively moved in parallel directions, or the bonding stage 41 is rotated in the horizontal plane by a rotating device (not shown), and the liquid crystal panel held by the bonding stage 41 is adjusted for adjustment. P is aligned with the relative bonding position of the bonding sheet F5 held by the bonding cylinder 32.

Further, in the present embodiment, the first bonding apparatus 13 is provided with a pair of third detecting cameras 36 for aligning the liquid crystal panel P in the horizontal direction above the bonding stage 41 as the bonding position. (Refer to Figure 5, Figure 6, and Figure 9).

The eighth drawing is a view for explaining the adjustment of the bonding position by the first bonding device 13.

In the eighth drawing, the drawing of the right side is attached to the arrangement position of the bonding sheet F5 of the bonding cylinder 32, and the drawing of the left stage is held by the liquid crystal panel P of the bonding stage 41. Match The explanatory diagram of the position is attached, and the drawing of the lower stage is an explanatory view of the adjustment amount of the stage 41.

In the eighth diagram, for the sake of convenience, one of the four second detecting cameras 35 is displayed as a second detecting camera 35.

As shown in the right part of the eighth figure, the corner of the bonded sheet F5 attached to the holding surface 32a is imaged by the second detecting camera 35.

In the following description, the detection positions (the optical axis extension positions of the two second detection cameras 35) obtained by the two second detection cameras 35 arranged along the rotation direction of the bonding cylinder 32 will be along. The distance in the circumferential direction of the bonding cylinder 32 between them is referred to as the inter-camera distance Lc. The inter-camera distance Lc is approximately equal to the length of the sheet piece of the above-mentioned bonded sheet F5.

For example, when the bonded sheet F5 moves at the inter-camera distance Lc with the rotation of the bonding cylinder 32, the position of the corner portion of the bonded sheet F5 is moved from the starting point Ep1 to the end point Ep2. The detection information of the second detection camera 35 (the position information of the start point Ep1 and the end point Ep2) is sent to the control device 25. The control device 25 is a distance Le between the start point Ep1 and the end point Ep2 in the direction parallel to the rotation axis of the bonding cylinder 32, as shown in the lower stage of the eighth drawing. The start point/end point deviation Le) is calculated as the correction angle α (tan α=Le/Lc).

As shown in the left part of the eighth drawing, the third detection camera 36, which will be described later, images the corner portion of the liquid crystal panel P held by the bonding stage 41. For example, the mark Pm is attached to each corner portion of the liquid crystal panel P (for example, three marks Pm1, Pm2, and Pm3 in the present embodiment). The detection information of the third detecting camera 36 (the position information of the first mark Pm1, the second mark Pm2, and the third mark Pm3) is sent to the control device 25. The control device 25 performs drive control of the bonding stage 41 based on the detection information of the third detecting camera 36, and performs alignment of the liquid crystal panel P held by the bonding stage 41. The control device 25 drives and controls the rotating device 45 according to the correction angle α to make the fit The stage 41 is rotated by an angle α in the horizontal plane. Thereby, alignment of the liquid crystal panel P with respect to the bonding cylinder 32 is performed.

The ninth drawing is a view for explaining a step of bonding the liquid crystal panel P to the sheet F5 by the bonding cylinder 32.

As shown in FIG. 9A, the control device 25 moves the bonding cylinder 32 to a predetermined position above the bonding stage 41. The control device 25 is attached so that the front end portion of the bonded sheet F5 attached to the holding surface 32a and the end portion of the liquid crystal panel P held by the bonding stage 41 are superposed on a plane. The alignment of the combined cylinder 32 with the bonding stage 41.

In the control device 25, the bonding cylinder 32 is lowered, and the front end portion of the bonding sheet F5 attached to the holding surface 32a is pressed against the end portion of the liquid crystal panel P from above. The bonding cylinder 32 is lowered so that the bonding sheet F5 is pressed against the liquid crystal panel P. At this time, the bonding sheet 32 presses the bonding sheet F5 held by the holding surface 32a on the liquid crystal panel P and rotates it, thereby bonding the bonding sheet F5 to the liquid crystal panel P.

As shown in FIG. BB, the control device 25 moves the bonding stage 41 in a direction orthogonal to the rotation axis of the bonding cylinder 32 with the rotation of the bonding cylinder 32 at the time of bonding. . In the present embodiment, the bonding cylinder 32 is rotated about the left side, and the bonding stage 41 is moved in the right direction of the paper surface. In addition, the bonding cylinder 32 may be moved to the left side of the paper surface while the bonding cylinder 32 is not rotated while the bonding stage 41 is being moved.

For example, the rotational driving of the bonding cylinder 32 is performed in synchronization with the movement operation of the liquid crystal panel P by the bonding stage 41. Thereby, generation of friction between the bonded sheet F5 and the liquid crystal panel P can be suppressed. Therefore, the bonding sheet F5 can be bonded to the liquid crystal panel P with a suppressed offset.

The bonding cylinder 32 has, for example, a bonding surface (adhesive layer) than the bonding sheet F5. F2a) is a weaker adhesion force, and the surface protective film F4a of the bonded sheet F5 can be attached and peeled off repeatedly. Therefore, the bonded sheet F5 which is pressed against the liquid crystal panel P on the side of the adhesive layer F2a is held by the holding surface 32a. The film is peeled off and bonded to the liquid crystal panel P side. In the present embodiment, the liquid crystal panel P is bonded to the bonded sheet F5 in the short-side direction of the display region P4 by the first bonding apparatus 13.

In the same manner, the bonding process of the bonding sheet F5 to the liquid crystal panel P is repeated in the same manner by repeating the operations of the eighth and ninth drawings.

In the second bonding apparatus 15, similarly, a pair of fourth detecting cameras 37 for aligning the liquid crystal panel P in the horizontal direction are provided above the bonding stage 41 as a bonding position ( Refer to the fifth figure). Each of the third detecting cameras 36 captures the left corners of the left side in the fifth drawing of the glass substrate (first substrate P1) of the liquid crystal panel P, for example, and each of the fourth detecting cameras 37 pairs the glass of the liquid crystal panel P, for example. The two corners on the left side in the fifth figure in the substrate are respectively imaged.

Further, in the third bonding apparatus 18, a pair of fifth detecting cameras 38 for performing alignment in the horizontal direction of the liquid crystal panel P are provided above the bonding stage 41 as a bonding position. Refer to the fifth figure). Each of the fifth detecting cameras 38 captures the two corner portions on the left side in the fifth drawing of the glass substrate of the liquid crystal panel P, for example. The detection information of each of the detection cameras 34 to 38 is sent to the control device 25. Among them, a sensor that replaces each of the detection cameras 34 to 38 can also be used.

As described above, the bonding stage 41 of each of the bonding apparatuses 13, 15, and 18 is driven and controlled by the control unit 25 based on the detection information of each of the detecting cameras 34 to 38. Thereby, the alignment of the liquid crystal panel P with respect to the bonding cylinder 32 in each bonding position is performed.

For the liquid crystal panel P, the bonded sheet is bonded by the aligned bonding cylinder 32 In this way, F5 suppresses the unevenness of the bonding of the optical member F1X, and the accuracy with respect to the optical axis direction of the optical member F1X of the liquid crystal panel P is improved, and the color and contrast of the optical display device are improved.

In the film bonding system 1 of the above-described embodiment, the first bonding apparatus 13 sets the sheet conveying direction or the bonding circle along the sheet conveying device 31 along the panel conveying direction of the secondary conveyor 7. The direction of movement of the barrel 32 (refer to the fifth figure). On the other hand, the second bonding apparatus 15 and the third bonding apparatus 18 are set along the sheet conveying direction in the sheet conveying apparatus 31 in the direction orthogonal to the panel conveying direction of the secondary conveyor 7, or The moving direction of the cylinder 32 is bonded (refer to the fifth drawing).

Here, the first cutting device 51 and the second cutting device 52 are, for example, CO ₂ laser cutters. However, the configuration of the first and second cutting devices 51 and 52 is not limited thereto, and other cutting means such as a cutting blade may be used.

The first cutting device 51 and the second cutting device 52 cut the sheet piece FXm bonded to the liquid crystal panel P into an endless shape along the outer peripheral edge of the display region P4. The first cutting device 51 and the second cutting device 52 are connected to the same laser output device 53. By the first cutting device 51, the second cutting device 52, and the laser output device 53, the remaining portion that is disposed outside the portion facing the display region P4 is separated from the sheet piece FXm to form a The cutting means of the optical member sheet FX of the size corresponding to the display region P4. The laser output required for cutting each of the sheet pieces F1m, F2m, and F3m is not so large, so that the high-output laser light outputted by the laser output device 53 can be divided into two to be supplied to the first cut. The breaking device 51 and the second cutting device 52.

In the present embodiment, the second sheet piece F2m and the third sheet piece F3m are bonded to the liquid crystal panel P, and then collectively cut, whereby the positional deviation of the second optical member F12 and the third optical member F13 is eliminated.

Further, the cutting process of the second sheet piece F2m and the third sheet piece F3m is also simplified.

The remaining liquid crystal panel P is cut by the second cutting device 52 and delivered to the second cutting and transporting position 7h of the secondary conveyor 7 by the seventh conveying device 65. The seventh conveying device 65 does not perform a turning operation for swirling the panel at the time of conveyance. Therefore, in the secondary conveyor 7 The liquid crystal panel P conveyed in the direction in which the long side of the display region P4 is conveyed in the direction of the conveyance direction is also formed so as to maintain the direction of the long side along the conveyance direction after being transferred to the second cutting and conveying position 7h again.

The liquid crystal panel P that has been transferred to the second cutting and transporting position 7h is transported by the secondary conveyor 7 to the bonding inspection position 7e downstream of the second cutting delivery position 7h in the transport direction.

At the bonding inspection position 7e, inspection of the workpiece (liquid crystal panel P) to which the film has been bonded is inspected by the inspection device 19 (whether the position of the sheet piece FXm is appropriate (whether the positional deviation is within the tolerance range) or the like ). The workpiece determined to be not the position of the optical member F1X with respect to the liquid crystal panel P is discharged to the outside of the system by a discarding means (not shown).

The liquid crystal panel P that has been transferred to the carry-out conveyor 6 is transported in a direction orthogonal to the transport direction of the sub-conveyor 7 while being placed on the rack 6c, and is carried out to the external device. .

This is accomplished by the bonding process of the film bonding system 2 as described above.

Hereinafter, a bonding process of the liquid crystal panel P by the bonding sheet F5 by the first bonding apparatus 13 will be described as an example. Here, the description of the bonding process by the second and third bonding apparatuses 15 and 18 having the same configuration as that of the first bonding apparatus 13 will be omitted.

In the first embodiment, the first bonding apparatus 13 cuts out a sheet piece (first sheet piece F1m) of the bonding sheet F5 larger than the display region P4 of the liquid crystal panel P by the first optical member sheet F1. The bonding cylinder 32 is attached to the holding surface 32a by rotating it. The first bonding apparatus 13 rotates the bonding cylinder 32 on the liquid crystal panel P on the bonding stage 41, thereby bonding the sheet sheets (first sheet sheets F1m) to which the sheet F5 is bonded. .

The bonding stage 41 is driven and controlled by the control device 25 based on the detection information of each of the detecting cameras 34 to 38. Thereby, the alignment of the liquid crystal panel P with respect to the bonding cylinder 32 is performed in each bonding position.

In the liquid crystal panel P, the bonded sheet F5 (sheet sheet FXm) is bonded to the aligned bonding cylinder 32, thereby suppressing uneven bonding of the sheet sheet FXm, and the sheet with respect to the liquid crystal panel P The accuracy of the optical axis direction of the material sheet FXm is improved, and the color and contrast of the optical display device are improved.

Here, the polarizing film constituting the optical member sheet FX is formed by stretching a PVA film (polyvinyl alcohol film) dyed with a dichroic dye, for example, but the thickness of the PVA film during stretching is uneven or two. The dyeing of the coloring matter is uneven, and unevenness in the optical axis direction may occur in the plane of the optical member sheet FX.

Therefore, in the present embodiment, the control device 25 determines the liquid crystal panel based on the inspection data distributed in the surface of the optical axis in each portion of the sheet piece FXm sheet sheet FXm of the memory device 24 (see FIG. 10). The bonding position (relative bonding position) of P with respect to the sheet piece FXm. Next, each of the bonding apparatuses 13, 15, and 18 is attached to the bonding position, and the liquid crystal panel P is aligned with the sheet piece FXm cut out by the optical member sheet FX, and the sheet piece FXm is bonded to the liquid crystal panel. P.

The method of determining the bonding position (relative bonding position) of the sheet piece FXm with respect to the liquid crystal panel P is as shown in FIG.

First, as shown in FIG. 12A, the plurality of inspection points CP are set in the wide direction of the optical member sheet FX, and the direction of the optical axis of the optical member sheet FX is detected at each inspection point CP. The timing of detecting the optical axis may be a period in which the raw material roll R1 is manufactured, or may be a period from the unwinding of the optical sheet FX by the raw material roll R1 to half cut. Optical component sheet FX optical axis direction data and light The position of the member sheet FX (the position in the longitudinal direction of the optical member sheet FX and the position in the wide direction) is stored in association with the memory device 24 (see FIG. 11).

In the control device 25, the data of the optical axis of each of the inspection points CP (inspection data of the in-plane distribution of the optical axis) is acquired by the memory device 24 (see the eleventh drawing), and the optical component piece of the portion where the sheet piece FXm is cut out is detected. The direction of the average optical axis of the material FX (the area defined by the slit line CL).

For example, as shown in FIG. 12B, the angle (offset angle) between the direction of the optical axis and the edge line EL of the optical sheet FX is detected for each inspection point CP, and the largest angle among the aforementioned offset angles is maximized (maximum angle When the offset angle is set to θ max and the minimum angle (minimum offset angle) is θ min , the average value of the maximum offset angle θ max and the minimum offset angle θ min is θ mid (=(θ max + θ Min)/2) is detected as the average offset angle. Next, the direction in which the average offset angle θ mid is formed is detected as the direction of the average optical axis of the optical sheet FXm with respect to the side line EL of the optical sheet FXm. In the above-described offset angle, for example, the direction in which the side line EL of the sheet piece FXm is rotated to the left is made positive, and the direction in which the right turn is made negative is calculated.

Next, the direction of the average optical axis of the optical member sheet FX detected by the above method determines the sheet piece so as to form a desired angle with respect to the long side or the short side of the display area P4 of the liquid crystal panel P. The position where the FXm is attached to the liquid crystal panel P (relatively attached position). For example, when the direction of the optical axis of the optical member F1X is set to a direction of 90° with respect to the long side or the short side of the display region P4 according to the design specification, the direction of the average optical axis of the optical member sheet FX is relative to the display. The long side or the short side of the region P4 is formed at 90°, and the sheet piece FXm is bonded to the liquid crystal panel P.

The cutting devices 51 and 52 detect a liquid crystal panel by means of a detecting means such as a camera. The outer peripheral edge of the display region P4 of P is cut into an endless shape along the outer peripheral edge of the display region P4 by the sheet piece FXm bonded to the liquid crystal panel P. The outer periphery of the display region P4 is detected by imaging an end portion of the liquid crystal panel P, an alignment mark provided on the liquid crystal panel P, or an outermost edge of a black matrix provided in the display region P4. On the outer side of the display region P4, a predetermined wide frame portion G (see the third drawing) in which a sealant for bonding the first and second substrates of the liquid crystal panel P is disposed is provided, and within the width of the frame portion G, The cutting of the sheet piece FXm by the cutting devices 51 and 52 is performed.

Here, the method of detecting the direction of the average optical axis in the plane of the optical member sheet FX is not limited to the above method. For example, one or a plurality of checkpoints CP are selected from among a plurality of checkpoints CP (refer to FIG. 12A) set in the wide direction of the optical component sheet FX, and optical is detected for each selected checkpoint CP. The direction of the axis is at an angle (offset angle) to the edge line EL of the optical member sheet FX. Next, the average value of the offset angles of the optical axis directions of the selected one or more checkpoints CP may be detected as an average offset angle, and the edge line EL of the opposite optical component sheet FX may be detected to form the aforementioned average shift. The direction of the angle serves as the direction of the average optical axis of the optical member sheet FX.

As described above, the film bonding system 2 of the present embodiment is formed by bonding the optical member F1X to the liquid crystal panel P, and includes a plurality of the liquid crystal panels that are transported on the production line along a predetermined transport direction. P, while the first optical member sheet F1 having a wider width than the short side of the display region P4 of the liquid crystal panel P is unwound from the material roll R1, the first optical member sheet F1 is made larger than the aforementioned After the long side of the display region P4 is cut into a longer length and formed into the sheet piece F1m, the sheet piece F1m is bonded to the first bonding device 13 on the one side of the liquid crystal panel P; a plurality of second or third optical sheets having a wider width than the long side of the display region P4 of the liquid crystal panel P, the plurality of liquid crystal panels P being transported thereon The component sheets F2 and F3 are unwound from the material roll R1, and the second or third optical member sheets F2 and F3 are cut into a sheet length by a length longer than the short side of the display region P4. After F2m and F3m, the sheet sheets F2m and F3m are bonded to the second or third bonding apparatuses 15 and 18 on the other side of the liquid crystal panel P; and the sheet bonded to the liquid crystal panel P The material piece F1m and the sheet pieces F2m and F3m are separated from each other on the outer side of the portion facing the display region P4, and the optical members F1X, F2X, and F3X having the size corresponding to the display region P4 are formed. The cutting devices 51 and 52 and the liquid crystal panel P are in the direction of the transport direction when the first bonding apparatus 13 is bonded to the first sheet piece F1m, and in the second or third bonding apparatus 15 and 18 When the second or third sheet pieces F2m and F3m are bonded to each other, the direction with respect to the conveyance direction is the same.

According to this configuration, similarly to the first embodiment, in the present embodiment, the sheet FXm attached by the first bonding apparatus 13, the second bonding apparatus 15, and the third bonding apparatus 18 is also attached. In time, it is not necessary to change the direction of the liquid crystal panel P, so that there is no need for a swing mechanism for swirling the liquid crystal panel P, which simplifies the device configuration.

Further, the optical member F1X can be accurately placed in the vicinity of the display region P4, and the frame portion G outside the display region P4 can be narrowed (see FIG. 3) to achieve enlargement of the display region and downsizing of the device.

Further, in the film bonding system 2, the first cutting device 51 and the second cutting device 52 are laser cutters, and the first cutting device 51 and the second cutting device 52 are the same laser output device 53. The lasers outputted by the laser output device 53 may be branched and supplied to the first cutting device 51 and the second cutting device 52.
