Production technology preventing deformation of tempered glass in hot shaping

Abstract

The invention discloses a production technology preventing deformation of tempered glass in hot shaping. The technological process comprises the following steps: preparing a glass substrate, and drawing a CAD engineering drawing by analyzing and designing the required figure; by referring to the drawing, sequentially performing practical mould making, mould positioning and on-substrate positioning; after the glass substrate is qualified according to quality inspection, performing on-substrate positioning processing of the glass substrate; heating, and performing constant-temperature setting; finally, cooling to obtain basic hot bending glass; by referring to the finished product inspection diagram, performing quality inspection on the basic hot bending glass; if the basic hot bending glassis qualified, continuing the processing; putting the qualified basic hot bending glass into a shaping jig to fix the shape; in cooperation with temperature regulation, automatically calibrating the hot-bent tempered glass flat, to obtain a finished product of hot bending tempered glass; and packaging the flat finished product of hot bending tempered glass for storage. According to the productiontechnology disclosed by the invention, the tempered glass is shaped by use of a precision mould, the glass surface blistering is avoided, and the tempered glass has the advantages of stable shaping, rare deformation and the like.

Description

technical field [0001] The invention relates to the field of inorganic non-metallic material processing, in particular to a production process for heat shaping and non-deformation of tempered glass. Background technique [0002] At present, there have been many material innovations for the protection of mobile phone screens in the market, but there is still a certain range of vacancies for the protection of 3D curved screens, which seriously hinders the development of 3D curved mobile phone film. Facing such market vacancies and pressures, it is urgent to solve the above problem of curved protective film. [0003] The research on 3D curved screen protection in the domestic mobile phone screen accessories industry is basically blank, and the current international research in this field is also in its initial stage. The current organic soft protective films such as PET / PE are still mainstream products in the market, but with the continuous updating of products, people have hi...
