A glass substrate integrated overflow forming control device

Abstract

The invention discloses a glass substrate integrated overflow forming control device. A drainage baffle is arranged on the outside of both ends of the overflow brick body, so that during the forming process of the glass substrate, the glass substrate is fixedly arranged at both ends of the overflow brick body. The drainage baffle prevents the glass liquid from extending along the two ends of the overflow brick body, thereby ensuring the accuracy of the glass substrate production size. The structure is simple, and it does not need to be supported by the cooling and holding mechanism. By setting the lower end of the drainage baffle, it can rotate relative to the drainage baffle The guide angle plate is driven by the transmission screw to drive the slider to move, so that the rotation angle of the guide angle plate can be changed to realize the change of the width of the glass substrate. This device is beneficial to the production of glass substrates of different sizes. The overflow device does not need to re-open the mold to design the drainage angle of the drainage baffle. The device has a simple structure, is easy to operate, reduces costs, ensures the production fluctuation and molding quality of the glass substrate, and ensures a more stable production.

Description

technical field [0001] The invention relates to the technical field of substrate glass manufacturing, in particular to an integrated overflow forming control device for a glass substrate. Background technique [0002] The substrate glass used in the production of flat panel displays such as TFT-LCD (Thin Film Transistor Display) and PDP (Plasma Display Panel) is manufactured by overflow down-drawing. In the forming process, molten glass melted by a glass melting furnace is supplied to Melt overflow down-draw molding device to manufacture. The overflow down-draw method is a kind of substrate glass production technology. The molten glass overflows through the top of the overflow tank and flows down from the outer surfaces of both sides of the overflow tank respectively, and meets at the bottom of the tank, cooling the clamping mechanism at both ends. Under the traction of the glass, the molten glass then enters the glass forming area of ​​the substrate. The overflow down-dra...

AI Technical Summary

Problems solved by technology

The change of plate width will cause the following problems: (1) limit the utilization rate of glass; (2) the fluctuation of side plate weight (the decrease of plate width or useful plate width will lead to the increase of side plate weight); (3) the change of plate thickness (thickness change will cause stress problem)
