Protection mechanism in glass etching device

Abstract

The invention relates to a protection mechanism in a glass etching device. The protection mechanism comprises a spacer bar and an O-shaped ring on the spacer bar, and two upwards slant centres are symmetrically arranged on the surface of the O-shaped ring. The protection mechanism is suitable for glass etching.

Description

technical field [0001] The invention relates to the field of protection mechanisms in glass etching devices, in particular to a protection mechanism in glass etching devices. Background technique [0002] In glass etching, glass is etched neatly in glass baskets. When the size of the glass is relatively large, the glass and the glass are easy to collide with each other, causing the glass to be scratched and resulting in defects after etching. The traditional way is to place spacer 1 between glass and glass, the structure of spacer 1 is as follows figure 1 As shown, an O-ring 2 is sheathed on the spacer rod 1, so as to avoid glass-to-glass contact. However, because the area of ​​the O-ring 2 in contact with the glass is relatively large, uneven etching is likely to occur at the contact portion with the glass. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a protection mechanism in a glass etching device that d...
