Description

Technical Field

[0001] The utility model belongs to the technical field of acid etching, and specifically relates to a supporting device for glass acid etching. Background Art

[0002] The current market demand is for mass production of LCD panels. During the thinning production process, the substrate is placed in an acid etching tool for etching. Because the tool has a fixing device that needs to bear the weight of the glass, special tooling and fixtures are needed to assist. Tooling and fixtures have become an indispensable part of acid etching production. Suitable tooling can greatly improve production efficiency, while avoiding the occurrence of acid etching defects, reducing pressure on subsequent processes, and improving the quality of the thinning and acid etching process.

[0003] The patent number is 201820835924.7, and a public specification published on December 4, 2018 discloses a bottom support device for spraying thinned glass for TFT substrates, which is applied to the technical field of parts and components of auxiliary equipment for the production of thin-film transistor liquid crystal displays. A plurality of grooves arranged at intervals are arranged on the support body of the bottom support device for spraying thinned glass for TFT substrates. One side of each groove is arranged to extend to the side position I of the support body, and the other side of each groove is arranged to extend to the side position II of the support body. The support body is a structure made of acid-resistant material. The bottom support device for spraying thinned glass for TFT substrates described in the utility model can reliably limit the load-bearing thinned glass laminate, avoid depressions and sharp edges during etching, reduce the risk of damage, reduce costs, and improve product quality.

[0004] In the above-mentioned prior art, the function of supporting the thinned glass laminate is limited by the groove portion provided on the supporting body. However, due to the large width of the supporting device, the flow of the acid is blocked during the flow process, which causes the acid etching rate of the acid in the device accessories to deviate, and ultimately leads to poor acid etching. The device of the utility model is designed with an opening on the original basis, so that the acid can flow more smoothly in the acid etching tool accessories, the flow direction will not change, and the difference in all acid etching rates is small, which can avoid poor acid etching and is beneficial to the improvement of the yield in the production process. Utility Model Content

[0005] The utility model aims to provide a glass acid etching supporting device which is convenient for acid liquid to flow.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a support device for glass acid etching, including a support seat, the glass is placed on the top surface of the support seat, the support seat is provided with a flow hole, the flow hole is located below the glass, and a flow groove connected to the flow hole is provided on one side of the support seat.

[0007] The supporting seat is a strip-shaped ivory plate.

[0008] The flow hole passes through the support seat.

[0009] The flow hole is vertical.

[0010] The flow holes are evenly arranged along the support seat.

[0011] The support seat is provided with mounting holes which penetrate through the two end portions of the support seat.

[0012] The technical effect of the utility model is as follows: a flow hole penetrating the support seat is provided on the support seat, and a flow groove is opened at the bottom of the support seat, and the number of acid etching inserts is consistent, so that there is a cavity at the bottom of each piece of glass, which is convenient for the flow of acid, and the acid flows more smoothly in the acid etching tooling accessories, and the flow direction does not change. The difference in all acid etching rates is small, which can avoid the occurrence of poor acid etching and is beneficial to the improvement of the yield in the production process.
