Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal panel folding apparatus formed by bonding two glass sheets. 2. Description of the Related Art As a conventional technique for dividing a large liquid crystal panel into product sizes, cutting lines for ear dropping, large splitting and small splitting are formed on the front and back surfaces of the liquid crystal panel. In addition, a cutting line for dropping the ears, a cutting line for large and small splits is made on the back of the liquid crystal panel, and the liquid crystal panel, in which each cutting line on the front surface is split in advance, is transported (sent) to the split position. In addition, the sheet is split while applying an impact on the cutting line by a splitting member such as a bar or a roll of the splitting device (the cut is made to penetrate the cutting line to be cut). However, since a suction table called a stage (a structure in which the mounting surface or the stacking surface of the liquid crystal panel and the inside of the suction box communicate with each other through a myriad of small holes) is used for the transfer means of the liquid crystal panel, the suction table is mounted on the suction table. The entire surface of the liquid crystal panel is strongly supported by suction. In such a situation, when the liquid crystal panel is split, the liquid crystal panel on the upstream side of the split line (next split liquid crystal panel) and the liquid crystal panel on the downstream side (folded liquid crystal panel, that is, large and small split liquid crystal panels) are used. Since there is no flexibility to allow movement at the part where the panel is separated from the panel, a scorching phenomenon (a strong processing force on the cut surfaces due to the division) occurs in the divided section, and there is a defect There was also a problem that the liquid crystal panel was damaged due to the formation of defective parts and a small piece remaining on the table. [0005] In particular, as shown in FIG. 8, when a terminal portion is formed at two edges sandwiching one corner of the liquid crystal panel on the CF side of the liquid crystal panel (to a product size), along the large and small cutting lines. An end forming cutting line is inserted, and the terminal forming cutting line is cut by a cutting device. [0006] In this case, the cutting line for forming the terminal portion is split, and then the cutting line for the large split and the small split is split. [0007] At this time, when the bending is applied on the cutting line of the large and small portions, the bent portion of the terminal portion is also bent and the broken portion of the terminal portion is squeezed again. Cause The cause of the AR surface side defect is also that the AR surface is reversely warped when the CF surface is divided after the AR surface is divided, and the AR surface disconnection is increased. [0009] When the CF surface is cut, it is completely cut. At that time, the liquid crystal panel extends in the width direction simultaneously with the division. [0010] In this case, since the suction of the liquid crystal panel is too strong for the support, the center is pressed down, and the squeezing of the divided section is further promoted. In addition, since the divided liquid crystal panels of large and small parts (product size) remain sucked on the suction table, there is also a problem that the liquid crystal panels cannot be immediately transferred to the next process or taken down after the division. Was. In view of the above, the present invention is intended to prevent the occurrence of a defect in the divided edge and to immediately transfer or take off the divided liquid crystal panel to the next step. [0013] In order to solve the above-mentioned problems, the present invention provides a push-up bar material which is raised and lowered by a suitable lifting means, and which is located immediately above the bar material and has a suitable lifting and lowering means. A first splitting device composed of a splitting member for applying a splitting force in accordance with the descent by the means, a dropping line on the front and back surfaces, a cutting line for large and small products, and a cutting line for forming a terminal portion only on the back surface. Each of the cutting lines on the front surface has been cleaved, and the rear surface of each of the liquid crystal panels has a lug, a terminal portion, and a large cutting line. 1 transporting means, a second transporting device for receiving and transporting the large liquid crystal panel split by the first folding device, and receiving and transferring the large liquid crystal panel unloaded by the second transporting device. Swivel provided to swivel Device, a third transfer device provided to receive and discharge the opposite end of the large liquid crystal panel turned by the turning device in the unloading direction, and a large liquid crystal panel transferred by the third transfer device And a second splitting device having the same configuration as the first splitting device provided so as to cut off each of the ear droppings, the terminal portion formation and the small cutting line. Embodiments of the present invention will be described with reference to the accompanying drawings. In the embodiment of the present invention, as shown in FIGS. 1 to 8, both sides (front and back) of a liquid crystal panel A formed by bonding two sheets of glass are cut in advance by a cutting cutter. 1, a large cutting line 2 and a small cutting line 3 of the product size are inserted (sscribed). In the liquid crystal panel a having a product size (according to the small size), an edge dividing cutting line 4 for dividing (for forming a terminal portion) two edges sandwiching one corner of the CF surface. There is (slive) there. Then, the cutting line 1, the large cutting line 2, and the small cutting line 3 on the AR surface of the liquid crystal panel A are cut in advance by a splitting machine (folding device). ) A cutting line 1 on the AR side of the liquid crystal panel A in the transfer direction, a major cutting line 2 intersecting the conveying direction, a cutting line 1 on the opposite side to the conveying direction, and an edge crossing the conveying direction. The dividing line 4 is split by the first splitting device B. In the case of the first folding device B, in the case shown in the drawing, the lower surface of the divided portion is raised by the push-up bar member 12 which rises by the extension of the cylinder 11, and the dividing force (addition force) is applied to the divided portion by the descending action of the cylinder 13. (By pressure or impact) and a dividing member 14 such as a bar or a roll. It should be noted that the cylinders 11 and 13 may be moved up and down by cams or cranks. Also, the first cutting device B has an ear drop cutting line 1,
The liquid crystal panel A is transported by the first transport device C so as to sequentially reach the large cutting line 2, the ear dropping cutting line 1, and the middle edge cutting line 4. The first transporting device C is a box-shaped air having a center for floating the supplied liquid crystal panel A by blowing air upward in the case shown in the figure and an infinite number of ejection holes on the top walls on both side sides of the center. A table 15, a guide rail 16 juxtaposed between the center and the side air table 15, and a slider 17 which is restrained by the guide rail 16 so as not to rotate and runs in the front-rear direction.
And a male screw 20 which is screwed into the screw hole 18 of the slider 17 and is driven at a fixed position by a motor 19 of numerical control, and both sides of the opposite edge of the liquid crystal panel A in the feeding direction ( A suction hose (not shown) is connected to a suction hose 21 (not shown) so as to suck the lower surface of FIG.

The liquid crystal panel A, which has been cut (by penetrating the cutting line), first receives the first transfer device C such that the cutout line 1 reaches the cutting line 1 by the first splitting device B as shown in FIG. (By numerical control). Next, the bar material 12 is raised by the extension action of the cylinder 11 to push up the lower surface of the liquid crystal panel A, and then the cutting member 14 is impacted by the separating member 14 by the action of the cylinder 13 on the cutting line 1 of the upper surface of the liquid crystal panel A. Or pressurizing force. Then, the ear drop cutting line 1 penetrates and breaks, and is divided. The separated ear edge falls downward. Of course,
Glass powder and the like accompanying the separation also fall and do not remain on the transport path. In addition, since there is no holding means such as suction before and after the dividing portion by the first folding device B, there is no squeak in the dividing section, and there is no defect in the dividing section edge (such as a clam-like drop). Next, as shown in FIG. 6, the first transporting device C is operated to feed the edge breaking line 4 to the first folding device B, and the edge breaking line 4 is sent by the first folding device B as described above. Break the wire by penetrating the disconnection 4. The fragments corresponding to the splitting fall, and the terminal portions P are formed on the liquid crystal panel A as shown in FIG. Thereafter, the first cutting device B is divided into two large cutting lines 2.
After the liquid crystal panel A is transported by the first transporting device C so as to reach (shown in FIG. 7), the liquid crystal panel A is divided by the first folding device B while penetrating the large cutting line 2. As described above, the edge cutting line 4, the large cutting line 2, and the ear dropping cutting line 1 are cut and sequentially cut while being penetrated by the first cutting device B. The large liquid crystal panel A ', which has been split and sequentially divided, is received by the second transport device E and transported while being sucked by the suction cup 24, and also by the turning device D as shown in FIGS. Turn 90 degrees. Then, the swiveled large liquid crystal panel A 'is sucked by the suction cup 29 of the third transfer device G to receive the load, and the suction of the suction pad 27 is released. When the cutting line 1 of the large liquid crystal panel A 'reaches the second folding device F by the third transport device G, the cutting line 1 is cut off in the same manner as the first folding device B described above. And divide it into pieces. The separated ear edge falls. Next, the third transporting device G causes the second folding device F
At the edge, the perimeter-divided line 4 is permeated by the second dividing device F, and is divided. The divided pieces that fall due to the division fall. After that, the small cutting line 3 is added to the second folding device F.
Is reached, the small cutting line 3 is penetrated by the second splitting device F and split, and the small liquid crystal panel a of the product size separated by the split is received by the suction cup 32 and carried out. As described above, the divided liquid crystal panel a is obtained by dividing the edge dividing cutting line 4, the small cutting line 3, and the ear dropping cutting line 1 while penetrating the second cutting device F. . At the time of the above-mentioned splitting, as in the case of the splitting by the first splitting device B, there is no squeak at the edge of the divided section, and the loss is eliminated. As described above, according to the liquid crystal panel splitting device of the present invention, the liquid crystal panel and the liquid crystal panel at the splitting and splitting portion by the penetration of each cutting line by the first and second splitting devices are provided. Since there is no support means such as suction of the large liquid crystal panel, there is no squeal in the cross section due to the split. For this reason, it is possible to eliminate the defect of the divided section and eliminate the occurrence of defective products. Further, since the divided small liquid crystal panel does not remain on the suction table as in the prior art, the small liquid crystal panel can be carried out, that is, taken down immediately after the division. Further, since unnecessary parts, such as ear edges and glass powder, do not remain in the fold portions (by the push-up bar member and the dividing member) of the first and second fold devices, the first and second fold devices can be smoothly divided. In addition, the liquid crystal panel is transported and unloaded, and the panel surface is not damaged.
