Problems solved by technology

Due to the tensile stress inside the strengthened glass, the edge of the strengthened glass is jagged after physical cutting, the glass strength is reduced, and the glass is easy to break. At the same time, because the cut glass is easy to break, the operator dare not use force to operate quickly, resulting in low production efficiency.

Abstract

The invention provides a method for cutting tempered glass. The method comprises the following steps of: coating photoresist on two surfaces of the tempered glass, and performing exposure and developing on the photoresist on one surface, so that a first cutting area is formed on the surface of the tempered glass; cutting a first groove on the surface of the tempered glass along the first cutting area; soaking the tempered glass in a hydrofluoric acid solution, and performing chemical cutting along the first groove; and removing the residual photoresist. According to the method, the tempered glass is cut by using the hydrofluoric acid solution, and the edge of the tempered glass is smoothed, so that the compressive strength on the edge of the tempered glass is improved, the breakage rate of the cut tempered glass is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a cutting process of glass, in particular to a cutting method of strengthened glass. Background technique [0002] After the glass is strengthened, uniform compressive stress is formed on the surface of the glass, and tensile stress is formed inside, so that the bending and impact strength of the glass can be improved. Due to the tensile stress inside the strengthened glass, the edge of the strengthened glass is jagged after physical cutting, the glass strength is reduced, and the glass is easy to break. At the same time, because the cut glass is easy to break, the operator dare not use force to operate quickly, resulting in low production efficiency. . Contents of the invention [0003] Based on this, it is necessary to provide a cutting method of strengthened glass with high compressive strength after cutting and high production efficiency. [0004] A method for cutting tempered glass, comprising the steps of: [0005] C...
