Description

Technical Field

[0001] The utility model relates to the technical field of fixtures for glass etching machines, and specifically relates to a glass sheet fixture for a glass etching machine. Background Art

[0002] A glass etching machine completes the etching process of glass by spraying a chemical solution onto the glass. Before the etching process, each small glass sheet needs to be vertically fixed in each basket on the moving platform. Several fixtures are required in the basket to hold the glass sheet. During the etching process, the moving platform will move back and forth. In order to keep each glass sheet basically in a vertical state, the two clamping arms of the fixture are respectively clamped on the surface of the glass sheet. The clamping arms are in surface contact with the glass sheet, having a large contact area, which will affect the etching quality. Especially at the contact position between the clamping arm and the glass sheet, the chemical solution cannot fully etch the glass sheet, resulting in a larger thickness. Therefore, it is necessary to make improvements.

[0003] As shown in the glass sheet fixture of a glass etching machine disclosed in the publication number CN 207313436 U, it has an installation part. Two clamping arms extend from one side of the installation part. The distance between the two clamping arms gradually increases from the inside to the outside. Several elastic spines are formed on the inner side surface of each clamping arm. The spines are arranged at intervals, and each spine is inclined towards the connecting part of the two clamping arms. The structure of the utility model is simple. The contact between the clamping arm and the glass sheet is point contact and flexible contact. The contact area between the clamping arm and the glass sheet is extremely small. During the glass etching process, the chemical solution can fully contact the contact position between the glass sheet and the clamping arm, enabling it to be fully etched. After the etching process, the thickness of each area of the glass sheet is very uniform, improving the glass etching quality. Summary of the Utility Model
