Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for cutting a glass substrate, and more particularly, to a jig for cutting a glass substrate serving as a base of a fluorescent display tube into individual pieces.

[0002]

2. Description of the Related Art Conventionally, when cutting a glass substrate of this kind, as shown in FIG. 3, it is a manual operation, and the glass substrate 1 is held with both hands and the scribed surface is turned down.
The glass substrates 1 were bent and cut with both hands around the cutting position to obtain individual glass substrates 1 ', 1'.

[0003]

Since the above-mentioned conventional glass substrate is cut by hand, it is very difficult to cut a glass substrate having a large thickness (3 mm or more).

Further, since the cutting is performed with the sense of both hands, there is a problem that the cut surface of the glass substrate does not have a right angle, and a predetermined accuracy cannot be ensured. In terms of safety, there is also a risk of cutting the finger because the end of the glass substrate is held by the finger.

An object of the present invention is to provide a glass substrate cutting jig for mechanically cutting a glass substrate.

[0006]

In order to achieve the above object, a glass substrate cutting jig according to the present invention provides a glass substrate cutting jig having a pair of glass substrate receivers, a clamp unit, and a cutting unit. a tool, receives glass substrate forming the said pair is provided at positions symmetrical about the axis, which rotates around the shaft, the clamp unit, the scribe line is at the center of the shaft Clamps the ends of the glass substrates aligned between the pair of glass substrate receivers on the respective glass substrate receivers,
The cutting unit includes a support block, and the support block.
Each glass base is rotatably supported by support pins at the left and right ends of the
Raises and lowers the bearing and the support block that contact the lower surface of the plate
And a bending and cutting mechanism having an air cylinder .

[0007]

The scribe line 1a of the glass substrate 1 is placed on a pair of glass substrate receivers 2, 2 symmetrical about the axis 8 with respect to the axis 8.
, The both ends of the glass substrate 1 are clamped, and the glass substrate 1 is bent and cut along the scribe line 1a by rotating the pair of glass substrate receivers 2 and 2 around the axis 8 in opposite directions. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention.

(Embodiment 1) FIG. 1A is a front view showing Embodiment 1 of the present invention, and FIG. 1B is a side view thereof. In FIG. 1, a shaft 8 is horizontally mounted on a support 7 of a base 9. A pair of glass substrate receivers 2 and 2
Are pivotally supported at symmetric positions. Each glass substrate receiver 2 is provided with a clamp unit 5 for clamping the glass substrate 1 between itself and the glass substrate 2 by driving the air cylinder 4. Also, on the front of the shaft 8,
A registration marker 3 is provided.

A cutting unit 6 is provided on the base 9 so as to be able to move up and down. The cutting unit 6 includes a support block 11 and support pins 1 at left and right ends of the support block 11.
2 has a bearing 13 rotatably supported on the lower surface of each glass substrate receiver 2 and an air cylinder 10 for moving the support block 11 up and down.

The alignment marker 3 and the glass substrate 1 shown in FIG.
Scribe line (cutting position) on the back of
The glass substrate 1 is set on the left and right glass substrate receivers 2 and 2 while matching with 1a. Thereafter, the right and left ends of the glass substrate 1 are clamped from above by a clamp unit 5 driven by an air cylinder 4.

In this state, the left and right symmetrical glass substrate receivers 2 and 2 about the axis 8 as the center of rotation are circularly moved upward from the horizontal position by the cutting unit 6 with the axis 8 as a reference, and the glass substrate 1 is moved along the scribe line 1a. Cut along. The circular motion is
An air cylinder 10 provided below the glass substrate receiver 2 drives the glass substrate receiver 2 upward through a support block 11, support pins 12, and bearings 13 for smooth sliding.

After the cutting of the glass substrate 1 is completed, the glass substrate receiver 2 is lowered to the original horizontal position, and the clamp unit 5
Releases the glass substrate 1.

(Embodiment 2) FIG. 2 is a front view showing Embodiment 2 of the present invention. The present embodiment shows an example in which a glass plate 1 with a multi-sided horizontal direction as shown in FIG. 4 is cut continuously. The glass substrate 1 with the multi-lateral direction is set on the supply conveyor 15 driven by the motor 14, transported by the supply conveyor 15, and stopped by the stopper 16 set so that the cutting position matches the alignment marker 3. The cutting operation is performed in the same manner as in the first embodiment.

Next, after the stopper 16 is released, the cut glass substrate (left end piece) is discharged from the discharge conveyor 1 driven by the motor 17.
Emitted at 8. The right end piece of the uncut glass substrate is
After moving to the position of the stopper 16 again by the supply conveyor 15, the above-mentioned cutting operation is repeated, and the horizontal multi-faceted glass substrate 1 is sequentially cut into individual glass substrates 1 '.

[0016]

As described above, according to the present invention, the glass substrate can be cut by machining without manual operation, and the safety can be improved.
