The first optical component F11 and the second optical component F12 are sized in the display area P4.

The cutting device 15 detects the display area P4 of the liquid crystal panel P by a detecting tool such as a camera. The outer peripheral edge is bonded to the layer FXm of the liquid crystal panel P along the outer periphery of the display region P4 so as not to be cut off (uninterruptedly) at the end of the layer FXm. The outer periphery of the display region P4 is detected by photographing the end portion of the liquid crystal panel P, the alignment mark provided on the liquid crystal panel P, or the outermost edge of the black matrix provided in the display region P4. A frame portion G (refer to FIG. 3) having a specific width is provided on the outer side of the display region P4, and is used to provide a sealant or the like for bonding the first substrate P1 and the second substrate P2 of the liquid crystal panel P. The cutting piece 15 is cut (cut line: WCL) by the cutting device 15 in the width of the frame portion G.

In the above embodiment, a carbon dioxide (CO ₂ ) laser cutter is used as an example of the cutting device 15, but the cutting device 15 is not limited to a carbon dioxide (CO ₂ ) laser cutting machine. As the cutting device 15, other members or devices having a cutting function such as a cutting blade can also be used.

Hereinafter, the first recovery device 30 will be described. The second recovery device 40 also has the same structure.

Fig. 5 is a schematic structural view of a first recovery device 30 relating to the first embodiment of the present invention. Fig. 6 is a plan view showing the first recovery device 30 according to the first embodiment of the present invention, in the case where the remaining portion Y is peeled off and recovered.

As shown in Fig. 5 and Fig. 6, the first recovery device 30 includes a peeling roller 36, and the outer peripheral surface 36s is wound around the remaining portion Y to rotate, and the adsorption stage 31 sucks the liquid crystal panel P to cause the liquid crystal panel P. The long side and the short side of the peeling roller 36 are inclined with respect to the rotary shaft 36a of the peeling roller 36, and the liquid crystal panel P is relatively moved in the vertical direction of the rotary shaft 36a of the peeling roller 36; and the feed roller 38 holds a part of the remaining portion Y. The rotation of the peeling roller 36, the movement of the suction table 31, and the clamping of the remaining portion Y by the feed roller 38 are all controlled by the control device.

As shown in Fig. 6, the remaining portion Y is formed into a rectangular frame shape in plan view. Further, in Fig. 6, the symbol Y1 is the long side portion along the long side of the liquid crystal panel P in the remaining portion Y, and the symbol Y2 is the short side portion along the short side of the liquid crystal panel P in the remaining portion Y, and the symbol Ye remains. A corner portion in which the end portion of the long side portion Y1 and the end portion of the short side portion Y2 in the portion Y overlap. The symbol θ1 is an angle formed by the long side of the liquid crystal panel P and the rotation axis 36a of the peeling roller 36, and the symbol θ2 is an angle formed by the short side of the liquid crystal panel P and the rotation axis 36a of the peeling roller 36.

In the present embodiment, the adsorption stage 31 is controlled by the control device so that the long side and the short side of the liquid crystal panel P are inclined at an angle of 45° with respect to the rotary shaft 36a of the peeling roller 36 (θ1=θ2=45°). The liquid crystal panel P is relatively moved in the vertical direction of the rotary shaft 36a of the peeling roller 36.

The peeling roller 36 is disposed in parallel with the vertical direction of the panel conveying direction. As number 5 As shown in the figure, the peeling roller 36 houses a clamp unit 37 that mechanically fixes (clamps) the corner portion Ye of the remaining portion Y. The peeling roller 36 is rotated in a state where the corner portion Ye of the remaining portion Y is fixed by the gripper unit 37 in accordance with the control of the control device to wind up the remaining portion Y.

The gripper unit 37 includes a grip portion 37a that fixes the corner portion Ye of the remaining portion Y, and a piston-cylinder mechanism 37b that is coupled to the grip portion 37a.

The nip portion 37a is exposed from the opening portion 36h which is a part of the detaching drum 36. The nip portion 37a is located below the peeling roller 36 in the initial state before the corner portion Ye of the remaining portion Y is fixed, and is in an open state in which the corner portion Ye of the remaining portion Y can be fixed.

The piston-cylinder mechanism 37b is slidably held by the nip portion 37a. The piston-cylinder mechanism 37b is adjusted between an open state before the corner portion Ye of the remaining portion Y is fixed by the nip portion 37a and a closed state when the corner portion Ye of the remaining portion Y is fixed.

The adsorption stage 31 sucks and holds the liquid crystal panel P from the lower side of the liquid crystal panel P by, for example, gas attraction (in the following description, it means that the second optical component bonding body PA2 is included).

The adsorption stage 31 includes a table main body 32 that is movable in the panel transport direction, a table portion 33 that can support the table main body 32 to move up and down, and a bottom portion for adsorbing the lower side of the liquid crystal panel P (display area P4). The inner suction pad 34 supported by the table portion 33 and the outer suction pad 35 supported by the table portion 33 for adsorbing the lower surface of the liquid crystal panel P outside (the electronic component mounting portion or the like).

The machine main body 32 is moved between a lower position of the first cutting device 15A and a lower position of the first rotating device 18 as shown in FIG. 1 by the control of the control device.

The liquid crystal panel P includes a bottom plate portion P6 (corresponding to the first substrate P1) composed of, for example, a thin film transistor (TFT) substrate, and a facing plate portion P7 disposed opposite to the bottom plate portion P6. . The opposing plate portion P7 includes a smaller substrate facing the bottom plate portion P6 (corresponding to the first The two substrates P2) and the liquid crystal layer P3 enclosed between the substrates. In the first recovery device 30, the liquid crystal panel P is disposed such that the surface facing the backlight side (the side of the bottom plate portion P6) faces upward.

The inner suction pad 34 of the table portion 33 is attracted to the lower side surface of the thick plate portion P8 including the opposing plate portion P7 in the liquid crystal panel P. The suction disk 35 on the outer side of the table portion 33 is attracted to the lower surface of the thin plate portion P9 mainly including the bottom plate portion P6 on the outer side of the thick plate portion P8 of the liquid crystal panel P. The lower side surface of the thick plate portion P8 is connected to the lower side surface of the thin plate portion P9 in a stepped shape, and the outer suction pad 35 is in contact with the slightly perpendicular step surface between the plates, thereby determining the position of the liquid crystal panel P with respect to the adsorption stage 31. Further, the display region P4 of the liquid crystal panel P is formed in the outer shape of the thick plate portion P8.

The adsorption stage 31 is configured to peel a part of the remaining portion Y under the peeling roller 36 by relative displacement under the control of the control device in a state where the corner portion Ye of the remaining portion Y is fixed by the gripper unit 37.

The feed roller 38 is controlled by the control device, and after the adsorption table 31 is relatively displaced under the peeling roller 36, a part of the remaining portion Y is clamped, and the same direction is taken toward the remaining portion Y of the peeling roller 36. The remaining portion Y is sent out in a tangential direction to the direction of rotation of the drum 38a in the nip portion of the drum 38.

The stage portion 33 is controlled by the control device, and when the table portion 33 is at the lowered position, each of the suction pads (the inner suction pad 34 and the outer suction plate 35) is attracted to the lower side surface of the corresponding portion of the liquid crystal panel P. From this state, the table portion 33 is displaced to the raised position, so that the table portion 33 rises integrally with the liquid crystal panel P that has been adsorbed.

Next, the action of the first recovery device 30 will be described.

7A to 9C are explanatory views showing the action of the first recovery device 30 relating to the first embodiment of the present invention. In addition, in the drawings 7A to 9C, for the sake of convenience of illustration, The moving direction of the adsorption stage 31 displayed is opposite to the direction in which the panel is conveyed as shown in Fig. 1.

First, as shown in Fig. 7A, when the table portion 33 is at the lowered position, the suction table 31 moves the corner portion Ye of the remaining portion Y below the nip portion 37a of the peeling roller 36.

In the present embodiment, as shown in FIG. 6, the long side and the short side of the liquid crystal panel P are inclined at an angle of 45° with respect to the rotary shaft 36a of the peeling roller 36 by the movement of the adsorption stage 31, and the liquid crystal is allowed to be liquid. The panel P moves in the vertical direction of the rotary shaft 36a of the peeling roller 36. Thereby, the long side portion Y1 and the short side portion Y2 of the remaining portion Y are uniformly peeled off.

However, in the present embodiment, the adsorption table 31 is moved without moving the peeling roller 36 by the control of the control device, but the method of relative movement is not limited to this method. For example, the method of moving the adsorption stage 31, moving only the separation roller 36, or moving the adsorption stage 31 and the separation roller 36 to move the adsorption stage 31 and the separation roller 36 can be applied to the present invention.

Next, as shown in Fig. 7B, the land portion 33 is raised, and the corner portion Ye of the remaining portion Y is brought close to the nip portion 37a. For example, the corner portion Ye of the remaining portion Y is moved into the opening portion of the grip portion 37a.

Next, as shown in Fig. 8A, the piston-cylinder mechanism 37b fixes the corner portion Ye of the remaining portion Y by the nip portion 37a by sliding the nip portion 37a.

Next, as shown in FIG. 8B, in a state where the corner portion Ye of the remaining portion Y is fixed by the nip portion 37a, the land portion 33 is lowered, and a part of the remaining portion Y is peeled off. Thereby, the corner portion Ye of the remaining portion Y is lifted by the nip portion 37a.

As shown in Fig. 6, the contact area of the corner portion Ye of the remaining portion Y with the liquid crystal panel P is smaller than the contact area of the long side portion Y1 of the remaining portion Y with the liquid crystal panel P, or the shorter side portion of the remaining portion Y. The contact area of Y2 with the liquid crystal panel P is smaller.

In the case where the remaining portion Y is peeled off from the long side portion Y1 or the short side portion Y2 of the remaining portion Y, since the contact area with the liquid crystal panel P must have a strong load carrying capacity, the force can be excessively applied to the remaining portion Y. A part of the remaining portion Y is torn to interrupt the recovery of the remaining portion Y.

On the other hand, in the present embodiment, since the remaining portion Y is peeled off from the corner portion Ye of the remaining portion Y, peeling can be reduced as compared with the case of peeling off from the long side portion Y1 or the short side portion Y2 of the remaining portion Y. The load at the time makes the peeling easy.

Next, as shown in Fig. 8C, after the corner portion Ye of the remaining portion Y is lifted by the nip portion 37a, the feed roller 38 grips a part of the remaining portion Y. By clamping a part of the remaining portion Y, the peeling position of the remaining portion Y can be restricted.

Here, between the peeling drum 36 and the feed roller 38, a power transmission mechanism 39 that transmits the turning force of the peeling roller 36 to the feed roller 38 is disposed. The power transmission mechanism 39 includes a first gear 39a that is assembled to the peeling drum 36, and a second gear 39b that is assembled to the first gear 39a and the drum 38a of the feed roller 38. Thereby, the rotation of the peeling roller 36 is synchronized, and the first gear 39a, the second gear 39b, and the feed roller 38 are rotated.

By the rotation of the peeling roller 36, it is used to peel off from the liquid crystal panel P and wind up the remaining portion Y. Specifically, a part of the remaining portion Y is sandwiched by the feed roller 38, and the corner portion Ye of the remaining portion Y is fixed by the nip portion 37a, and the remaining portion Y is taken up by the rotation peeling roller 36. The feed roller 38 synchronizes the rotation of the peeling roller 36 by the power transmission mechanism 39, and sends the remaining portion Y in the same direction in the winding direction of the remaining portion Y of the peeling roller 36.

As shown in Fig. 9A, when the peeling roller 36 is further rotated, the remaining portion of the remaining portion Y which is not peeled off (the long side portion Y1 and the short side portion Y2 of the remaining portion Y) are conveyed from the panel. The side of the swim gradually peeled off.

At this time, the adsorption stage 31 is such that the long side and the short side of the liquid crystal panel P are inclined with respect to the rotary shaft 36a of the peeling roller 36, and the liquid crystal panel P is oriented in the vertical direction of the rotary shaft 36a of the peeling roller 36 (Fig. 9A). Move in the direction of the arrow). The suction stage 31 synchronizes the rotation of the peeling roller 36 and moves in this direction. In this manner, the rotation of the peeling roller 36 is synchronized, and the first gear 39a, the second gear 39b, and the feed roller 38 are rotated, and the suction table 31 is moved in this direction.

Next, as shown in Fig. 9B, the adsorption stage 31 is further moved in this direction away from the peeling roller 36. On the other hand, by the rotation of the peeling roller 36, the remaining portion Y wound up to the peeling roller 36 is released from the state of being nipped by the feed roller 38. Then, the remaining portion Y is restored from the wound state to a straight line in the side view by its own elastic force.

Further, as shown in Fig. 9C, the grip portion 37a is opened by the control of the control device for discarding the remaining portion Y to the recovery tank 50 disposed below.

Further, after the recovery of the remaining portion Y, for example, the adsorption stage 31 returns to the original position, and the stage portion 33 is lowered to a certain extent. Hereinafter, after the adsorption stage 31 adsorbs the liquid crystal panel P on the upstream side, the same processing is repeated.

As described above, according to the film bonding system 1 of the first embodiment of the present invention, after the layer sheet FXm larger than the display area P4 is bonded to the liquid crystal panel P, the remaining portion Y of the layer sheet FXm is cut, whereby An optical component corresponding to the size of the display region P4 is formed on the surface of the liquid crystal panel P. Thereby, the optical component can better ensure the accuracy of the optical component when it is disposed in the display region P4, and can reduce the frame portion outside the display region P4 to achieve the expansion of the display region and the miniaturization of the device.

Further, when the remaining portion Y cut from the layer sheet FXm is recovered, peeling is performed from the corner portion Ye of the remaining portion Y, and since the contact area is small, peeling can be performed with a weak force, and the remaining portion can be suppressed. A part of the remaining portion Y is torn, and the remaining portion Y can be continuously recovered without breaking without interrupting the recovery of the remaining portion Y.

Further, the adsorption stage 31 causes the long side and the short side of the liquid crystal panel P to be inclined with respect to the rotary shaft 36a of the peeling roller 36, and the liquid crystal panel P is oriented in the vertical direction of the rotary shaft 36a of the peeling roller 36 (the arrow direction of FIG. 9A). The movement is performed, so that when the remaining portion Y is peeled off, the additional force applied to the peeling portion can be suppressed. Therefore, the remaining portion Y of the frame shape as a whole can be peeled off from the liquid crystal panel P.

Further, since the feed roller 38 synchronizes the rotation of the peeling roller 36, the entire remaining portion Y of the frame shape can be smoothly peeled off from the liquid crystal panel P.

Further, in the adsorption stage 31, the long side and the short side of the liquid crystal panel P are inclined at an angle of 45° with respect to the rotary shaft 36a of the peeling roller 36, and the liquid crystal panel P is moved in the vertical direction of the rotary shaft 36a of the peeling roller 36. The long side portion Y1 and the short side portion Y2 of the remaining portion Y can be uniformly peeled off. Therefore, the entire remaining portion Y of the frame shape can be smoothly peeled off from the liquid crystal panel P.

Further, in the present embodiment, a mechanical jig that fixes the corner portion Ye of the remaining portion Y by mechanical force is used as the gripper unit 37, but the fixing method (clamping method) is not limited thereto. For example, a vacuum chuck can also be used to vacuum attract the corner portion Ye of the remaining portion Y.

Further, in the present embodiment, an example in which the remaining portion Y is peeled off and recovered from the corner portion Ye by the recovery device has been described, but the present invention is not limited to this method.

For example, as shown in Fig. 10, the recovery device can peel and recover the remaining portion Y from a portion CP of the short side portion Y2. In this case, the adsorption stage 31 is controlled by the control device so that the long side of the liquid crystal panel P is perpendicular to the rotary shaft 36a of the peeling roller 36 ( θ 3 = 90°), and the liquid crystal panel P is along the peeling roller 36. The vertical direction of the rotary shaft 36a is relatively moved. Further, a part CP of the short side portion Y2 of the remaining portion Y is fixed by the nip portion 37a (refer to Fig. 5). Hereinafter, the remaining portion Y is peeled and recovered by the same operation as in the embodiment.

The foregoing structure can also be applied to the present invention.

Further, the recovery device can peel and recover the remaining portion Y from a portion of the long side portion Y1. That is, the recovery device can fix the remaining portion Y and perform peeling recovery from the optical assembly.

However, the present invention is not limited to the above embodiment. For example, the remaining portion Y is not limited to a frame shape in which the plan view is a rectangle, and the plan view may have various shapes such as an L shape.

Further, although the case where the polarizing film is bonded to the liquid crystal panel has been described, the optical member is not limited to being bonded to the liquid crystal panel as an optical display member, and for the liquid crystal panel, for example, organic electroluminescence (OEL, Organic) is also applied. Electro-Luminescence panel. The polarizing film is not limited to being bonded to the polarizing film as an optical component, and for the polarizing film, for example, an antireflection film, a light diffusing film, or the like is also used.

In the above embodiment of the present invention, the front surface of the liquid crystal panel P is the first surface, and the reverse surface is the second surface. However, the front surface of the liquid crystal panel P may be the second surface, and the reverse side is the first surface. surface.

Heretofore, a preferred embodiment of the present invention has been described with reference to the accompanying drawings, and the present invention is not limited to the embodiments.
