Description

[Detailed description of the invention] The present invention relates to a glass plate insertion device for inserting a rectangular glass plate into a cassette, for example, a glass substrate insertion device for cassette unit processing useful in the pre-manufacturing of liquid crystal display elements. be.

In the manufacturing process of liquid crystal display elements, most of the transportation, processing, and processing of glass substrates is performed in units of cassettes that can accommodate a large number of stacked glass substrates.

In the manufacturing process, some operations, such as cleaning the glass substrate, are performed by placing the glass substrate in a cassette, but operations such as screen printing on the glass substrate are performed by removing the glass substrate from the cassette.

Therefore, during the manufacturing process of a liquid crystal display element, the process of removing the glass substrate from the cassette, processing it, and then putting it back into the cassette is repeated several times.

The thickness of the glass substrate used for liquid crystal display elements is usually 0.3
Since glass substrates as thin as ~0.7 mm are used, sufficient consideration must be taken when handling glass substrates in the manufacturing process of liquid crystal display elements.

When the cassette that stores the glass plate is made of a resin molded product, the shrinkage rate of the cassette is not constant, and even if the cassette is simply moved at a constant pitch relative to the glass that is being transferred to a fixed position, the glass plate of the cassette will shrink. There is a drawback that the height of the storage groove and the height of the glass plate cannot be matched, resulting in damage to the glass plate.

For this reason, conventionally about 5% of the glass was damaged.

SUMMARY OF THE INVENTION An object of the present invention is to provide a glass plate insertion device that eliminates the drawbacks of the prior art described above, reduces damage to glass substrates, and reduces downtime of an automatic machine.

In order to achieve the above object, the present invention is characterized in that a part of the guide mechanism that positions the glass plate when inserting the glass plate into the cassette positions and holds the cassette at the same time as the glass plate.

An embodiment of the present invention will be described below with reference to the drawings.

Figures 1, 2, 3 and 3 show an embodiment of the present invention, and when the button is pressed in the figure, the cassette 1 is placed on a lifting mechanism (not shown) and the glass plate 2 is A groove 1' for supporting the glass plate 2 and a structure 1'' for positioning the cassette 1 are formed on both sides of the cassette 10, which rises one pitch each time it is moved.

The movable rail 3 is provided on the outside of the fixed rail 4 provided to face the cassette 1, and moves the glass plate 2 placed on the fixed rail 4 toward the cassette 1 at a predetermined pitch by rectangular movement. #It is something to be transferred.

The small rail 5 is attached to the movable rail 3 so as to be located inside the fixed rail 4, and is used to transfer the glass plate transferred on the fixed rail 4 to the tip of the fixed rail 4.

The pushing plate 9 is supported by the supporting plate 8 fixed between the small rails 50 and moves in the same direction as the movable rail 3 to push the glass plate 2 at the tip of the fixed rail 4 into the cassette 1.

The guide piece 7 is slidably supported by the fixed rail 4 and fixed plates 10 installed on both sides of the cassette 1.
It is configured to slide by the operation of a cylinder 6 fixed to.

One end of the guide piece 7 guides the groove 1'' of the cassette 1, and the other end guides the glass plate 2.

The operation of the glass plate insertion device having the above configuration will be explained with reference to FIG.

In FIG. 3, the steps proceed in the order 81g.

a First, a lifting mechanism (not shown) is operated to position the cassette 1 in the vertical direction.

The glass substrate 2 has been placed on the fixed rail 4 after the process before inserting it into the cassette 1.

b Next, as the movable rail 3 rises, the glass plate 2
is placed on the small rail 5 and rises to a certain height O.

C Subsequently, the movable rail 3 moves forward in the direction of the cassette 1, and the glass plate 2 is also carried in the direction of the cassette 1.

d The movable rail 3 is lowered and the glass plate 2 is moved to the fixed rail 4.
placed near the tip of the

Then, the cylinder 6 operates, and the guide surface 7 of the guide piece 7
' to position the glass plate 2, and at the same time, engage the guide 7'' with the groove 1' of the cassette 1 to remove the cassette 1.
positioning.

Another glass plate 2', which has undergone the previous process, is then supplied on the fixed rail 4 to the position where the glass plate 2 was originally placed, similarly to the glass plate 2 described above.

e The movable rail 3 moves backward in the direction away from the cassette 1 and returns to the position of step a.

f As in the previous step, the movable rail 3 rises again, and the glass plate 2' is placed on the small rail 5 and rises to a certain height.

g As in step C, the movable rail 3 moves forward in the direction of the cassette 1 and the glass plate 2' is carried toward the cassette 1. At the same time, the push plate 9 moves the glass plate 2' that has already been positioned by the guide 7' in step d. Push plate 2 and cassette 1
into groove 1'.

The process continues to step d below.

By repeating these steps, the glass plates are sequentially inserted into the cassette 1.

As described above, according to the present invention, since the handling cassette and the glass plate are simultaneously positioned by the guide piece, the glass plate can be inserted into the cassette securely, and damage to the glass plate can be prevented. It can be reduced to 0.4% or less, which is extremely effective for streamlining the manufacturing process of liquid crystal display panels, for example.
