Description

Technical Field

[0001] The utility model belongs to the field of ultra-thin flexible glass production, and specifically relates to an ultra-thin flexible glass micro-etching device. Background Art

[0002] Ultra-thin flexible glass has the characteristics of ultra-thinness, wear resistance, good light transmittance, high strength, bendability, and good resilience. In order to improve the surface strength of the current ultra-thin flexible glass cover, potassium nitrate in a high-temperature molten state is often used for sodium-potassium ion replacement to achieve the purpose of chemical tempering. However, due to the increase in product stress after tempering and product expansion, micro-cracks on the surface of the product are caused, resulting in a significant decrease in the impact resistance of the glass surface. The in-plane micro-etching technology can effectively passivate the cracks and edge collapse in the glass surface, but the etching liquid residual on the surface of the ultra-thin flexible glass when the basket is lifted can easily cause uneven acid etching on the product surface, affecting the product yield.

[0003] To solve the above problems, patent document CN114436547A discloses a method for manufacturing and processing flexible glass products, comprising the following steps: step 1: attaching a glass raw material to a carrier plate I through an adhesive composition to fix the glass raw material to the carrier plate I; step 2: chemically etching and thinning the fixed glass raw material and the carrier plate I and / or physically grinding and polishing the fixed glass raw material and the carrier plate I to thin the glass raw material to a specified thickness and remove its surface appearance defects to obtain a flexible glass fixed by the carrier plate I; step 3: laminating one or more pieces of flexible glass fixed by the carrier plate I with the carrier plate II through an adhesive composition, and then cutting and CNC forming to obtain a flexible glass I fixed by the carrier plate II; step 4: separating the carrier plate I, the carrier plate II and the flexible glass fixed by the carrier plate II through ultraviolet light irradiation and / or heat treatment to obtain a flexible glass I; step 5: tempering the flexible glass I in step 4 to obtain a flexible glass product, but this application cannot solve the above problems.
