Description

TECHNICAL FIELD [0001] The present invention relates to an upper movable tempered glass manufacturing apparatus,

The present invention relates to an upper movable tempered glass manufacturing apparatus, and more particularly to an upper movable tempered glass manufacturing apparatus for etching a glass substrate using an etching liquid.

Tempered glass used for a mobile phone, a PDA, a monitor, a building, and various industrial glasses is advantageous in that it has thin scratches and has excellent transparency. However, in order to produce a tempered glass having excellent hardness and strength, a tempering process of glass is required.

In general, glass strengthening is divided into physical strengthening and chemical strengthening. In the physical strengthening, the glass is heated to a temperature between about 550 ° C. and 700 ° C., and quenched to strengthen the internal strength. It is mainly used for manufacturing. However, such physical strengthening can not be applied to a thin sheet glass which can not sufficiently provide a temperature difference between the glass surface layer and the center layer. In the case of a glass having a small thermal expansion coefficient, strengthening is difficult. There is a disadvantage that the portion does not have a uniform temperature difference. Also, since the work is performed at a relatively high temperature, deformation of the glass may occur.

On the other hand, the chemical strengthening is to strengthen the glass by substituting the potassium ion of the sodium ion and the potassium nitrate solution in the glass by immersing the thin plate glass in the potassium nitrate solution of about 450 ° C. for 3 hours or more to mainly strengthen the thin thin plate glass . Chemical strengthening can be applied to both thin sheet glass and complicated shaped glass by strengthening the glass through ion exchange, and there is no risk of deformation during processing. In addition, it has advantages of high precision, superior physical strength in terms of strength, and cutting after reinforcement.

Such a chemical strengthening process generally involves heating the glass to be tempered at a temperature between about 300 and 450 DEG C and immersing the heated glass in molten potassium nitrate at a temperature of about 380 DEG C or higher for a period of time to compress By forming the stress layer, the glass can be strengthened.

According to the conventional tempered glass manufacturing apparatus, since the high temperature potassium nitrate salt is opened to the atmosphere in the course of drawing or drawing the glass substrate into the high temperature potassium nitrate salt, heat loss occurs and the thermal efficiency is lowered, .

The process for manufacturing the tempered glass of the upper movable tempered glass manufacturing apparatus according to an embodiment of the present invention is as follows.

The treatment solution (which may be a potassium nitrate solution according to one embodiment of the present invention) in the bath chamber 100 is heated to the heat treatment temperature and the injection port 110 is closed by the slide plate 300 . The upper transfer chamber 200 is moved from the upper right side of the bath chamber 100 to the upper transfer position of the cassette 600 by driving the upper transfer chamber motor 230. After the upper transfer chamber 200 is stopped, the upper and lower transfer members 400 are lowered to the hooking position of the cassette 600 by the upper transfer unit 400.

The cassette 600 is loaded on the cassette transfer unit 700 and the cassette 600 is transferred to the upper and lower transfer positions by driving the cassette transfer motor 710. [ The cassette 600 is moved and stopped until it is hooked on the hook 520 and the cassette 600 is lifted together with the upper transfer body 500 and transferred into the upper transfer chamber 200.

The upper transfer chamber 200 is moved to a position directly above the bass chamber 100 or into the insertion position and the slide plate 300 is moved by driving the slide plate motor 340 to open the injection port 110. Accordingly, the bath chamber 100 and the upper transfer chamber 200 are opposed to each other, and the inside is allowed to pass therethrough. As the upper and lower transfer bodies 500 are lowered, the cassette 600 is immersed in the processing solution to heat the glass substrate.

Further, the glass substrate withdrawing process after the completion of the heat treatment can proceed in the reverse order of the above process.

4, the inside of the upper transfer chamber 200 is exposed to high temperature by the treatment solution, and the connection portion 421 between the upper feeding shaft 420 and the gear portion 411 is also exposed to high temperature. Therefore, it is preferable that the connection portion 421 is made of a material resistant to high temperature and having a sufficient thickness.

According to the conventional tempered glass manufacturing apparatus, thermal deformation occurs when the apparatus is exposed to a high-temperature treatment solution, so that breakage of the apparatus is caused and operation failure of the apparatus occurs. In addition, when the glass substrate is heat-treated, the treatment solution is opened to the outside atmosphere, which causes a large heat loss. Further, since the cassette must be inserted from the upper part of the chamber containing the potassium nitrate salt, the operation position of the cassette is high, and accordingly, movement and loading of the cassette are very inconvenient.

However, in the upper movable tempered glass manufacturing apparatus according to the present invention, the slide plate 300 is not thermally deformed even when exposed to a high temperature by applying a thermal deformation preventing structure to the slide plate 300. In addition, it is possible to prevent the high temperature treatment solution from being exposed to the atmosphere, thereby minimizing heat loss. Further, the cassette 600 can be loaded at a low position very close to the ground, and can be automatically transferred to the processing solution, so that the operation is very convenient.

As described above, the technical ideas described in the embodiments of the present invention can be implemented independently of each other, or can be implemented in combination with each other. While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not to be limited to the details thereof and that various changes and modifications will be apparent to those skilled in the art. Various modifications and variations are possible within the scope of the appended claims.
