Description

Falling-off preventing device for end material cutting

Technical Field

The utility model relates to a surely draw when the outside end material is cut apart around the dysmorphism of base plate cuts line, the end material prevents device that drops.

Background

As is well known, in order to obtain a shaped substrate, a large panel (substrate) is individually divided into a size slightly larger than the size of a product, and a cutting line of the shaped substrate is cut on the individually divided substrate.

By dividing the outer side of the cutting line (end material) of the scribed substrate, a special-shaped substrate is formed.

When the cutting line is cut, a half-cut line which is easy to divide the end material of each side is cut at each corner of the substrate, and the half-cut line is from the special-shaped cutting line of the substrate to the edge of the substrate.

Next, the end materials on both sides of the substrate are gripped by the gripping jaws at the front ends of the robot arms, and the end materials are divided by dividing the irregular cutting lines together with the half-cut lines in accordance with the twisting action of the gripping jaws (see patent document 1).

Detailed Description

Next, an embodiment of the present invention will be described with reference to fig. 1 and 2 of the drawings.

The utility model discloses a drop preventing device when end material is cut apart is the processing as shown in figure 1 rectangle form base plate A person, this base plate A uses well-known veneer, liquid crystal base plate, and organic EL base plate etc. for example there is the downside to be the glass board and the multilayer film person of layerding on this glass board etc. for the processing of base plate A, is cutting apart the square form (showing rectangle form in the drawing) single check of big piece base plate in-process product size (as is known, this single division is cut the cutting line of drawing X direction and Y direction at the top and bottom, cuts apart this cutting line of cutting, borrows this multi-disc base plate A who obtains single division).

As shown in fig. 1, a special-shaped cutting line B is cut along the entire periphery (one round is bypassed) of the substrate a, and then, when the special-shaped cutting line B is cut, a half-cutting line C is cut between the edge of the substrate a and the special-shaped cutting line B at each corner of the substrate a (two lines are parallel at each corner in the figure).

As shown in fig. 3 and 5, a table 1 that rotates on a plane by a rotating device D is provided, and a substrate a placed on the table 1 is sucked and held by a suction holding device E provided on the table 1.

As shown in fig. 3 and 5, the rotating device D is provided with a motor M to mount the upper end of the rotating shaft 25 at the center of the lower surface of the table 1. As shown in fig. 6 and 7, the suction holding device E sucks the inside of the table 1 through a connection hose by providing a plurality of small holes 2 on the top wall of the hollow table 1, thereby sucking and holding the substrate a on the top wall of the table 1.

The edges of the table 1 are sized so as not to protrude significantly from the edges of the substrate a.

As shown in fig. 3, 6, and 7, the robot arms 3 are disposed so as to be positioned outside the side of the substrate a, and the front ends of the robot arms 3 are provided with grippers 4 for gripping the upper and lower surfaces of the substrate a.
