SUMMERY OF THE UTILITY MODEL

[ problems to be solved by the invention ]

In the division system of patent document 1 (see fig. 6 and 7), as the cylinder extends, the dividing member such as a bar or a roller is lowered to the divided portion (on the scribe line), and a dividing force (pressurizing force or impact force) acts on the dividing member to divide the bar or the roller.

Further, according to the division method of patent document 2 (see fig. 6, 7, and 8), the bar material is divided while being pressed against the scribe lines of the divided portions, as in the method of patent document 1.

In this way, stress due to the pressure or impact force of the divided member such as a bar or a roller is forcibly divided, so that a beautiful divided surface cannot be obtained, and the divided surface is scratched or broken due to scratching, which causes defective products. That is, a corner defect may occur on the product side.

The reason for this is the effect of impact stress. Therefore, the utility model discloses a mode does: the clamping claw clamps the end material to the position near the cutting line of the end material part, and the clamping part twists and divides the end material part, thereby avoiding the above disadvantages, especially the effect on the long end material of the dividing edge.

Detailed Description

The following describes embodiments of the present invention with reference to the attached drawings. As shown in fig. 4, the substrate a for dividing each edge member according to the embodiment of the present invention uses an organic EL substrate or the like in addition to a known single plate and a liquid crystal substrate, and for example, there is a substrate having a glass plate at the lower side and a multilayer film laminated on the lower glass plate, and a cut line B having a shape corresponding to the upper surface of the multilayer film is cut on the lower surface of the glass plate.

Further, a half cut line B 'is cut at each corner portion of the cutting line B, and the half cut line B' is provided to facilitate the cutting of each edge member C from the cutting line B toward the edge of the substrate a.

As is known, the substrate a is a rectangular substrate obtained by cutting lines in the X direction and the Y direction on both sides of a large panel, dividing the cut lines, and dividing the substrate into a plurality of pieces.

As shown in fig. 1 to 3, the table D receives the substrate a thereon (at the time of transfer or supply by hand or the like).

As shown in fig. 1 and 3, in the table D, as a means for moving in the front-rear direction, a slider 3 provided on the lower surface of a seat 2 is slidably engaged with rails 1 arranged in the front-rear direction, a drive shaft 5 is a rotating device attached to the seat 2, and is reversibly driven at 45 °, 90 °, and 180 ° with the operation of a motor 4, and the upper end of the drive shaft 5 is attached to the center of the lower surface of the table D, thereby rotating the table D.

Of course, the substrate A placed on the table D is supported on the table D by the suction holding device E.

As shown in fig. 1, as the suction holding device E, a hollow box is used as the table D, the inside of the box is sucked, and the substrate a placed on (accompanied by supply to) the table D is sucked and held on the top wall of the table D by providing numerous small holes 6 in the top wall of the table D.

As shown in fig. 3, a male screw 7 is rotatably provided at a fixed position parallel to the rail 1, a female screw 8 provided on the lower surface of the table D is screwed to the male screw 7, and the male screw 7 is driven reversibly by a motor 9, so that the table D can be slid in the front-rear direction of fig. 1 to adjust the position of the table D (the front-rear direction of fig. 1).

Further, the double-wrist robot arm F, F is disposed on the left and right outside one edge of the table D (on the front side of the one side of the parallel long edge shown in fig. 1), and the base on the tip side thereof is stationary.

The fixed positions of the distal end base portions of the two articulated robot arms F, F are attached to both end portions of the horizontal beam 11 of the illustrated gantry 10 and hung.

The reason why the hanging system is adopted is that the both robot arms F, F do not obstruct the supply of the substrate a onto the table D and the taking up of the substrate a after the end member C is divided, but the installation system is not limited.

The table D is provided with a notch 12 at its edge, which is fitted into the front end jaw G of the robot arm F, F, so that the jaw G does not collide with the edge of the table D when the jaw G is turned and swung.

Thus, when the end material C to be divided by the substrate A is clamped by the clamping jaw G, the collision between the front end edge of the clamping jaw G and the edge of the table D can be avoided, and the clamping operation can be smoothly carried out.

Next, when the end members C at the respective edges of the substrate a are divided, the table D is rotated by 180 ° to exchange the two parallel sides, or the table is rotated by 90 ° to exchange the long side and the short side, and the end members C at the respective sides are divided as shown in fig. 4 to 6. The divided end material C is collected in a box (not shown). In the figure, 16 is a mounting substrate.

In addition, when the end material dividing apparatus for the special-shaped substrate is used for processing and a notch portion recessed inward is provided at the edge of the processed special-shaped substrate, the end material dividing apparatus of the present invention may be provided with a device disclosed in japanese utility model registration No. 3215843, and the notch portion may be provided by first operating the inner side of the scribe line subjected to the pretreatment with a preceding folding and cutting device and then operating the following folding and cutting device.
