Problems solved by technology

In the existing production process, the method of controlling the shape of the glass plate is mainly solved by adjusting the distribution of the glass processing temperature and reducing the shaking of the glass plate, but when the shape of the glass plate changes due to external factors, the above method cannot quickly change the The shape is restored, and the production can only be interrupted until the shape of the glass plate is restored, and then the production can be continued

Embodiment Construction

[0020] The present invention is described in further detail below in conjunction with accompanying drawing:

[0021] The invention provides a device for adjusting the shape of a glass plate, such as figure 1 As shown, the overflow down-draw forming equipment 1 is included, and the glass sheet outlet of the overflow down-draw forming equipment 1 is provided with a deflector 2, and a traction roller 3 is arranged under the deflector 2, and the forming of the glass plate is under the traction roller 3. In the area, a fork device 7 is arranged on the surface of the glass plate, and the fork device 7 wants to exert an opposite force on the glass plate relative to the existing shape; the fork device 7 is a U-shaped structure, and the U-shaped structure is in contact with the surface of the glass plate The part has a certain radian; the shifting fork device 7 is connected with the rotating shaft 8, and the shifting fork device 7 can perform an arc-shaped reciprocating motion around t...

Abstract

The invention discloses a device for adjusting the shape of a glass plate. The device comprises a flow guide plate, wherein the lower part of the flow guide plate is connected with a traction roller; the upper part of the flow guide plate is arranged below a glass plate flowing-out hole of overflowing and pulling-down molding equipment; a shifting fork device is arranged below the traction roller; the shifting fork device is in contact with a glass plate surface; an acting force, which is opposite to an existing shape, is applied to the glass plate through the shifting fork device; a cutting device is arranged below the shifting fork device. In a production process of a liquid crystal glass substrate, the deformed glass plate can be rapidly recovered, so that the production continuity of the glass plate is realized and the production quality is improved.

Description

technical field [0001] The invention belongs to the technical field of glass substrate manufacturing and relates to a device for adjusting the shape of a glass plate. Background technique [0002] Substrate glass used for flat panel display technology, the thickness of the glass plate is 0.3-1.4mm, it is one of the key components of flat panel display, in the process of producing substrate glass, it is very important that the shape of the glass should be consistent. [0003] At present, in the process of producing glass substrates for displays, the surface of the glass plate produced by overflow down-drawing is only in contact with air, so it has good plane smoothness. Therefore, many enterprises adopt overflow down-drawing method. In the process of the method, the glass sheet overflows from the overflow brick, and the glass sheet is stretched to the required thickness by the traction roller, and then cut into the glass sheet required by the user through the cutting machine....
