Description

  The present invention relates to a device that cuts off an end material of a deformed substrate used in, for example, an in-vehicle display panel.

  As is well known, an organic EL substrate has been used as a display substrate such as an in-vehicle display panel in addition to a liquid crystal substrate. After scribing a deformed cutting line on the substrate, an outer peripheral portion of the cutting line is obtained. The odd-shaped substrate is obtained by dividing the end material (removing the material along with the division) (see, for example, Patent Documents 1 and 2 as the above-mentioned end material dividing method).

Japanese Patent No. 3759450 Japanese Patent No. 4907104

  By the way, according to the dividing method of Patent Document 1 (see FIGS. 6 and 7), the dividing force (pressing force and impact force) applied to the dividing member such as a bar material and a roll that descends to the divided portion (on the scribe line) as the cylinder extends. It is designed to divide by acting.

  Further, according to the dividing method of Patent Document 2 (see FIGS. 6, 7, and 8), similarly to the method of Patent Document 1, the dividing bar material is divided while being pressed onto the scribe line that is the dividing portion.

  According to the above-mentioned method, since it is forcibly divided by the stress due to the applied pressure or impact force of the dividing member such as a bar material or roll, a beautiful divided section cannot be obtained, and the divided section is crushed or cracked due to galling. Will cause defective products. That is, chipping can be performed on the product side.

The factor is that the impact stress is applied.
In view of this, the present invention is to eliminate the above-mentioned various inconveniences by grasping to the vicinity of the cutting line of the end material portion with a clamping claw and twisting the grasped portion to divide it. This is because it has an effect on the division of the long end material of the edge.

  In order to solve the above-described problems, the present invention is directed to a table for receiving a supply substrate on an upper surface, suction holding means provided to support the supply substrate on the table, and a turn provided to turn the table. Means, a pair of left and right robot arms arranged with the base supported on the left and right in front of one long side edge of the table, and the edge of the cutting by the gripping claw of the tip of the robot arm on the edge of the table A configuration comprising a notch portion provided so as to avoid a collision between the grip claw and the edge of the table is adopted.

  As described above, according to the odd-shaped substrate end material cutting apparatus according to the present invention, the substrate placed on the table is sucked and held by the suction holding means, and the edges of the both ends of the end material on the long side edge of the holding substrate are held. After holding by the chuck of the double-arm robot arm and holding the center part of the long edge edge by the center gripping claw, the robot arm chuck is twisted and swung, and the center gripping claw is twisted by the swinging means. Swing and cut off the end material at the part of the scribe line. In addition to the above, turn the table about 45 °, and double the short side of one end facing diagonally forward and the other side facing diagonally backward. The arm is gripped by the gripping claws of the robot arm and divided, and the table is turned by the turning means so that the end material of the short edge ends in the front-rear direction. Torsional rocking by rocking means The remaining short-side end material is repositioned by the turning means, and the center-holding claw is torsionally swung via the swinging means, and the remaining long-side end material is divided by the gripping claws of the front and rear robot arms. And the torsional rocking by the rocking means of the center gripping claw.

  For this reason, the edge material on each side can be divided very efficiently by changing the position of the edge of the board as the table turns as well as the robot arm chuck and center gripping claw, or one of them. There are specific effects that are possible.

And when the end material is divided by the chuck or center gripping claw of the robot arm, the torsion by the chuck or center gripping claw does not hinder the torsional division of the end material in the notch provided on the edge of the table. The torsional cutting of the end material can be performed smoothly, the edge of the cutting can be free of cracks, cracks can be eliminated, and there can be no cross-sections resulting in defective products. In the set, the support side of the terminal is provided independently at the left and right sides of the edge of the board, so the operating range of the left and right robot arms is (extremely) large, and the gripping position of the end material Even if there is, there is also a peculiar effect that division work becomes possible without any trouble.

  Of course, in addition to turning 45 °, the table can be turned 90 ° or 180 ° to change the position (grip position) of each edge.

It is a top view which divides and processes the end material of this device. It is the top view which changed the holding position of the end material. It is a side view same as the above. It is a top view of the board | substrate before parting a scrap. It is the top view which divided | segmented the end material of the long side edge of a board | substrate. It is the top view which divided | segmented the end material of the short edge of a board | substrate.

Next, an embodiment of the invention will be described with reference to the accompanying drawings.
As shown in FIG. 4, the substrate A for dividing the end material on each side of the embodiment of the present invention uses an organic EL substrate in addition to a well-known single plate and a liquid crystal substrate. Is formed by laminating a multilayer film on the lower glass plate, and a deformed cutting line B matching the lower surface of the glass plate and the upper surface of the multilayer film is scribed.

  Note that, at each corner portion of the cutting line B, a semi-cut line B ′ that makes it easy to divide the end material C on each side from the cutting line B toward the periphery of the substrate A is scribed.

  As is well known, the substrate A described above scribes a rectangular substrate by scribing X- and Y-direction cutting lines on both sides of a large panel, and dividing the cutting lines into single pieces. It has gained.

  D shown in FIGS. 1, 2 and 3 is a table for receiving the substrate A described above on the upper surface (supplied during transfer or by hand).

  As shown in FIGS. 1 and 3, the table D slidably engages a slider 3 provided on the lower surface of the seating material 2 with a rail 1 parallel in the front-rear direction as a travel means in the front-rear direction. The upper end of the drive shaft 5 that is reversibly driven at 45 °, 90 °, and 180 ° is attached to the center of the lower surface of the table D in accordance with the operation of the motor 4 as the turning means installed on the seat member 2, and the table D is rotated. It is supposed to let you.

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

  As the suction holding means E, as shown in FIG. 1, a hollow box is used for the table D, the inside of the box is sucked, and countless small holes 6 are provided on the top wall of the table D. The substrate A placed on the table D (with supply) is sucked and held on the top wall of the table D.

  As shown in FIG. 3, a male screw 7 that freely rotates at a fixed position parallel to the rail 1 is provided, and a female screw 8 provided on the lower surface of the table D is screwed into the male screw 7. By reversibly driving the male screw 7, the table D can be slid in the front-rear direction in FIG. 1 to adjust the position of the table D (front-rear direction in FIG. 1).

  Further, on the left and right sides of one side of the table D (on the front side of one side of the parallel long side shown in FIG. 1), robot arms F and F having a fixed base on the end side are arranged. It is.

  As the stationary type of the end bases of both the articulated robot arms F, F, a suspension system is used by installing them at both ends of the horizontal beam 11 of the illustrated portal frame 10.

  The reason for adopting this suspension method is that both the robot arms F and F are not obstructed as the substrate A is supplied onto the table D and the substrate A is taken up after the end material C is divided. The installation method is not limited.

  Further, the gripping claws G of the robot arms F and F are inserted into the edges of the table D so that the gripping claws G avoid a collision with the edges of the table D and the gripping claws G are twisted and swung. A notch 12 is provided to eliminate the collision between the table D and the gripping claws G.

  Then, when the end material C to be divided of the substrate A by the gripping claws G is clamped, a collision with the front edge of the gripping claws G against the edge of the table D can be avoided and a smooth gripping operation can be performed.

Then, when dividing the end material C at each edge of the substrate A, the table D is rotated by 180 ° so that two parallel sides are interchanged, and the table D is rotated by 90 ° so that the long side and the short side are interchanged. From FIG. 6, the edge material C of each side is divided.
The divided end material C is collected in a box (not shown).
In the figure, 16 is an installation base.
