The layer sheet conveying device 31 has a take-up portion 31a for holding a strip-shaped first optical component The roll drum R1 of the layer F1, and the first optical component layer F1 is wound up along the longitudinal direction thereof; the cutting device 31b applies a half cut to the first optical component layer F1 unwound from the roll drum R1; 31c, the first optical component layer F1 after the half cut is wound at an acute angle to separate the bonding layer sheet F5 from the separation layer sheet F3a; and the winding portion 31d is kept alone after being wound up through the blade edge 31c. The separation roller R2 of the layer F3a is separated.

Further, although omitted from the drawings, the layer sheet conveying device 31 has a plurality of guide rollers that wind the first optical module layer F1 along a specific conveyance path. The first optical module layer F1 has the same width as the display region P4 of the liquid crystal panel P (corresponding to the short side length of the display region P4 in the present embodiment) in the horizontal direction (ply width direction) perpendicular to the conveyance direction. .

The winding portion 31a located at the beginning of the layer conveying device 31 and the winding portion 31d at the end of the layer conveying device 31 are, for example, driven in synchronization with each other. Thereby, the unwinding portion 31a continuously winds up the first optical component layer F1 in the conveyance direction, and the winding portion 31d winds up the separation layer sheet F3a that has passed through the blade edge 31c. In the layer conveyance device 31, the upstream side in the conveyance direction of the first optical module layer F1 (separation layer sheet F3a) is referred to as the layer conveyance upstream side, and the downstream side in the conveyance direction is referred to as the sheet conveyance downstream side.

Each time the cutting device 31b winds the first optical component layer F1 up to the length of the display region P4 in the longitudinal direction perpendicular to the width direction of the layer (corresponding to the length of the long side of the display region P4 in the present embodiment) At the time of length, one part of the thickness direction of the first optical component layer F1 is cut across the entire width in the width direction of the layer (half-cut).

The cutting device 31b transmits the tension in the first optical component layer F1, and does not cause the first optical component layer F1 (the separation layer F3a) to be broken (the separation layer F3a having a specific thickness remains), and the cutting is performed. The front and rear positions of the broken blade are half cut, which is deep to the vicinity of the interface between the adhesive layer F2a and the separation layer F3a. Alternatively, a laser device can be used instead of cutting the blade.

In the half-cut first optical component layer F1, the optical module body F1a and the surface protective film F4a are cut in the thickness direction thereof to form a transverse line across the entire width of the first optical component layer F1 in the layer width direction. The first optical component layer F1 is divided into sections having a length corresponding to the long side of the display region P4 in the longitudinal direction by the transverse line. The partitions are each one of the plies (first optical component F11) of the ply F5.

The blade 31c is located below the first optical component layer F1 which is conveyed slightly horizontally from the left side to the right side of FIG. 6, and is formed to extend at least across the entire width of the first optical component layer F1 in the layer width direction. The blade 31c is in sliding contact with the side of the separation layer F3a of the first optical component layer F1 after the half cutting, and is wound around the acute angle.

The blade 31c is such that the first optical component layer F1 is wound at its acute angle at its acute angle. When the first optical component layer F1 is folded back at an acute front end of the blade 31c, the separation layer F3a is peeled off from the bonding layer F5. At this time, the adhesive layer F2a of the bonding layer sheet F5 (the bonding surface with the liquid crystal panel P) faces downward. Immediately above the front end portion of the blade 31c is a separation layer peeling position 31e, and the arc-shaped holding surface 32a of the bonding head 32 comes into contact with the front end portion of the blade edge 31c from above, so that the surface protective film of the layer of the laminated layer sheet F5 is adhered F4a (the opposite side to the facing surface) is adhered to the holding surface 32a of the fitting head 32.

The bonding head 32 is parallel to the width direction of the layer, and has a convex arc-shaped holding surface 32a below. The holding surface 32a has a weaker adhesive force than the bonding surface (adhesive layer F2a) of the bonding layer sheet F5, for example, and the surface protective film F4a of the bonding layer sheet F5 can be repeatedly adhered and peeled off.

The bonding head 32 is attached to the blade 31c, and has an axis along the width direction of the layer as a center, is parallel to the longitudinal direction, and is inclined to move along the curved surface of the holding surface 32a. When the bonding layer sheet F5 is adhered and adhered, and the bonding layer sheet F5 which is adhered and adhered is bonded to the liquid crystal panel P, the labeling is appropriately performed. The tilt of the head 32 moves.

The bonding head 32 is attached to the blade at the curved end side of the holding surface 32a from above with the holding surface 32a facing downward and the curved end side of the holding surface 32a (the right side of FIG. 6) being the lower side. The front end portion of 31c is adhered to the front end portion of the bonding layer sheet F5 at the separation layer peeling position 31e to the holding surface 32a. Thereafter, the bonding layer sheet F5 is continuously unwound and the bonding head 32 is tilted and moved, whereby the layer of the bonding layer sheet F5 is entirely adhered to the holding surface 32a.

The bonding head 32 can perform a lifting operation of a specific distance above the separation layer peeling position 31e and the first bonding position 11c, and can appropriately move between the separation layer peeling position 31e and the first bonding position 11c. The bonding head 32 is coupled to the driving device 33, and can be driven during the lifting, the moving, and the tilting movement.

When the bonding layer sheet F5 is adhered to the holding surface 32a, the bonding head 32 is detached from the driving device 33, for example, after the end portion of the bonding layer sheet F5 is adhered to the holding surface 32a. From this state, the tilting movement is passively accompanied by the unwinding of the bonding layer sheet F5. When the bonding head 32 is tilted to move until the bonding layer F5 is entirely adhered to the holding surface 32a, the tilting movement is locked in the inclined state by, for example, engagement with the driving device 33, and in this state, the tilting movement is performed. Moves over a fitting position 11c.

When the bonding layer 32 is adhered to the liquid crystal panel P, the bonding head 32 is actively tilted by, for example, the driving device 33, and the bonding layer F5 is attached along the bending of the holding surface 32a. Attached to the upper side of the liquid crystal panel P to be surely bonded.

Below the end portion before the blade 31c, a first detecting camera 34 is provided which detects the edge portion on the downstream side of the layer transporting of the layer sheet of the layer F5 at the portion. The detection data of the first detection camera 34 is transmitted to the control device 25. Control device 25 is, for example, first detecting camera 34 When the timing of the downstream end of the bonding layer sheet F5 is detected, the layer sheet conveying device 31 is temporarily stopped, and thereafter, the bonding head 32 is lowered to adhere the front end portion of the bonding layer sheet F5 to the holding surface 32a.

When the first detecting camera 34 detects the downstream side end of the bonding layer sheet F5 and temporarily stops the layer sheet conveying device 31, the control device 25 performs cutting of the bonding layer sheet F5 by the cutting device 31b. That is, along the detection position of the first detection camera 34 (the optical axis extension position of the first detection camera 34) and the cutting position along the cutting device 31b (the advance and retraction position of the cutting blade of the cutting device 31b) The distance of the layer transport route corresponds to the length of the layer of the laminated layer F5.

The cutting device 31b is movable along the layer transport path, and the distance between the detection position of the first detecting camera 34 and the cutting conveyance path between the cutting positions of the cutting device 31b is changed by the movement. The movement of the cutting device 31b is controlled by the control device 25, and when the bonding layer sheet F5 is cut by, for example, the cutting device 31b, the distance of the layer of the laminated layer sheet F5 is rolled up, and when it is cut, In the case where there is a deviation between the broken end and the specific reference position, the deviation is corrected by the movement of the cutting device 31b. Further, the cutting of the bonding layer sheet F5 having a different length may be performed by the movement of the cutting device 31b.

The first detecting camera 34 (detecting unit) can also detect the defect mark printed on the bonding layer sheet F5. This defect mark is marked by inkjet or the like from the side of the surface protective film F4a when the defect roll is found in the first optical component layer F1 at the time of manufacture of the roll reel R1. The bonding layer sheet F5 on which the defect mark is detected does not adhere to the liquid crystal panel P after being adhered to the bonding head 32, but moves to a discarding position avoiding the first bonding position 11c, and is overlapped and attached to the waste layer. Pieces and so on. Further, when the defect mark is detected, a step of cutting the defect of the bonding layer sheet F5 with a minimum width and discarding it may be designed.

When the bonding layer sheet F5 moves from the separation layer peeling position 31e toward the first bonding position 11c, it adheres to the both corners of the bonding layer sheet F5 of the holding surface 32a (for example, the proximal end portion of the front end portion) The two corners are each photographed by a pair of second detecting cameras 35. The detection data of each of the second detecting cameras 35 is transmitted to the control device 25. The control device 25 confirms the horizontal direction of the bonding layer sheet F5 with respect to the bonding head 32 (the direction in which the bonding head 32 moves and its vertical direction and the direction of rotation of the vertical axis center), for example, based on the imaging data of each of the second detecting cameras 35. position. In the case where the relative positions of the bonding head 32 and the bonding layer sheet F5 are different, the bonding head 32 performs position alignment by using the position of the bonding layer sheet F5 as a specific reference position.

At the first bonding position 11c of the first rotary machine tool 11, one of the position detection alignments for performing the horizontal alignment of the liquid crystal panel P on the first bonding position 11c is performed. At the second bonding position 11d of the second rotary machine tool 16, a pair of fourth detection cameras 37 for performing positional alignment in the horizontal direction on the second bonding position 11d of the same liquid crystal panel P are provided. Each of the third detecting cameras 36 captures, for example, the two corner portions on the left side in the fifth drawing of the glass substrate (first substrate P1) of the liquid crystal panel P. Each of the fourth detecting cameras 37 captures, for example, the two corners on the left side in the fifth drawing of the glass substrate of the liquid crystal panel P.

At the third bonding position 16c of the second rotary machine tool 16, a pair of fifth detection cameras 38 for performing positional alignment in the horizontal direction on the third bonding position 16c of the liquid crystal panel P are provided. Each of the fifth detecting cameras 38 captures, for example, the two corner portions on the left side in the fifth drawing of the glass substrate of the liquid crystal panel P. The detection data of each of the detection cameras (the first detection camera 34 to the fifth detection camera 38) is transmitted to the control device 25. Alternatively, a sensor may be used instead of each of the detecting cameras (the first detecting camera 34 to the fifth detecting camera 38).

A position alignment table 39 on which the liquid crystal panel P is placed and whose positional alignment in the horizontal direction can be performed is provided on each of the rotary machine tools (the first rotary machine tool 11 and the second rotary machine tool 16). The position calibration table 39 is based on the detection of each of the detection cameras (the first detection camera 34 to the fifth detection camera 38). The data is driven and controlled by the control device 25. Thereby, the liquid crystal panel P of the respective bonding positions (the first bonding position 11c, the second bonding position 11d, and the third bonding position 16c) of the first rotary table machine 11 and the second rotary machine tool 16 can be performed.
