Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a glass plate scoring device for scoring a glass plate for cutting.

<Prior Art> In recent years, with the development of electronic equipment, glass plates have come to be widely used as one of the electronic components of liquid crystal displays and the like. Liquid crystals have specific molecular arrangements that can be controlled by voltage to convert optical changes into visual information.

For this reason, glass substrates used in liquid crystal displays cannot be used as products if there are scratches or chips on the edges, so a protective film may be attached to the surface of the glass substrate. be.

On the other hand, glass substrates are produced by cutting a large original plate into a predetermined size by an operation called multi-piece cutting, and after processing such as chamfering, the product is made into a product. When cutting multiple pieces, cutting lines are formed in a grid pattern on one side of the original glass plate, and the original plate is broken along the grid lines to obtain glass substrates.

A conventional incision making device will be explained based on FIGS. 10 and 11. FIG. 10 shows a plan view of a conventional incision making device, and FIG. 11 shows a side view thereof.

The creasing device 1 is provided with a vacuum table 2, and a first creasing tool 3 and a second creasing tool 4 are provided on the vacuum table 2 so as to be driven in horizontal directions perpendicular to each other. A glass plate 5 is positioned and fixed on the vacuum table 2.

In the above-mentioned creasing device 1, after positioning and fixing the glass plate 5 on the vacuum table 2, the first creasing tool 3 is moved (X
direction) to make a score in the X direction on the surface of the glass plate 5. After returning the first scoring tool 3 to its original position, move the second scoring tool 4 (in the Y direction) to score the surface of the glass plate 5 in the Y direction. return to its original position.

In this way, square-shaped creasing is performed on the surface of the glass plate 5 by the creasing machine [1].

By the way, in cases where protective films are pasted on both the front and back sides of the glass plate, make cuts in the film on the back side of the glass plate that are the same as the squares on the front side so that the film can be broken with the film still attached. There are cases.

In this case, two of the above-mentioned creasing machines M1 are arranged side by side, and a reversing machine is arranged between the two creasing machines M1 to make the creasing on the front and back surfaces of the glass plate 5.

The glass plate 5 on which the score has been made is sent to an adjacent table and broken along the cut score.

<HWIi to be solved by the invention> In the conventional creasing device 1, positioning of the glass plate 5,
A reciprocating motion of the creasing tool 3 and a reciprocating motion of the second creasing tool 4 are performed to create creasing on one glass plate 5. For this reason, it took a long time to perform high-speed processing. It is conceivable to increase the speed by arranging a large number of creasing devices 1 in parallel, but in this case, a large amount of space is required.
