A method for enhancing the mechanical strength of glass

Abstract

Provided is a method for enhancing the mechanical strength of glass. The glass comprises a top surface, a bottom surface, and at least one side surface. The method comprises: forming protection layers on the top surface and the bottom surface, wherein the protection layers expose an area which is on the top surface and which is close to the side surface and an area which is on the bottom surface and which is close to the side surface; etching the side surface of the glass and one side surface of each protection layer; and removing the protection layers. In the method for enhancing the glass mechanical strength of glass, the side surface of the glass is made flat by etching the glass. Stress concentration does not occur when the side surface of the glass undergoes collision so that the mechanical strength of the glass is enhanced.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a method for improving the mechanical strength of glass. Background technique [0002] At present, many industries, such as the liquid crystal display industry, need to use glass as a substrate, and complete the manufacture of electronic products by forming components on the substrate, such as thin film transistors. [0003] For the sake of convenience and cost considerations in the process, usually a large-sized glass is produced first, and then the large-sized glass is cut into a plurality of small and medium-sized glasses in an appropriate way, such as by laser, according to the demand. [0004] see figure 1 , figure 1 It is a side view of the glass 10 after cutting. The side surface 100 of the glass 10 is a cut surface, which presents the microstructure as shown in the figure, that is, the side surface 100 is not a flat surface, but protrudes up and down and concave in the mi...

Problems solved by technology

[0005] Since the junction of the upper surface 102 and the side surface 100, and the junction of the lower surface 104 and the side surface 100 are very sharp, so in the subsequent process, such as a thinning process, stress concentration will occur when encountering a collision, so that the glass 10 Cracks or missing corners occur, and even cause the glass 10 to break, which leads to poor production yield of the glass 10

[0006] In addition, when glass 10 is used to make electronic products, such as the screen of a handheld device, the mechanical strength of the side surface 100 is fragile, resulting in poor quality of the electronic product.

[0007] Therefore, there is indeed a need to propose a solution to the problem that the mechanical strength of the side surface of the above-mentioned glass is fragile after cutting
