[0002] With the development of the ultra-thin glass and flexible foldable markets, the advantages of non-uniform thickness ultra-thin grooved glass cover plates have gradually emerged in the folding screen mobile phone industry, and the demand for products has gradually increased. At the same time, the production and processing technology of non-uniform thickness ultra-thin grooved glass cover plates has also become the focus of industry attention. The improvement of product quality and production efficiency will be the most important link in the development of this product. In the previous production process of non-uniform thickness ultra-thin grooved glass, the groove etching process section is to immerse the product grooved area into the etching liquid through the upper and lower clamps. The tooling plays a fixed role in the grooved glass and realizes the corresponding function in the groove etching machine. The existing ultra-thin grooved glass etching process is to clamp the glass on the existing tooling, put the tooling as a whole into the acid etching tank, and etch the glass at a certain rate to meet the dimensional process requirements. The existing tooling process has the following shortcomings and undesirable conditions that are difficult to improve: 1. The thickness of the glass currently produced is mostly 30-40μm, and the glass is brittle and easy to bend at this thickness. 1. When the tooling is working in the acid tank, in order to promote the flow of acid, the tooling will be thrown, but this action will cause the flow direction and movement of the acid in the tank to be irregular, resulting in different etching rates and poor glass appearance and uneven plate thickness; 2. The area of ​​the product that requires a groove only accounts for about 5% of the product, but in the actual etching process, the tooling and the glass need to be put into the acid tank as a whole, which requires a lot of etching liquid, resulting in waste. The repeated use of etching liquid causes changes in the conditions before and after etching, making it difficult to ensure product quality.
