Description

Technical Field

[0001] The invention belongs to the field of glass substrate detection, and in particular relates to a tool for detecting the roughness of a glass substrate. Background Art

[0002] The edges of glass substrates are sharp and irregular after cutting. Edge grinding can make the geometric shape and tolerance of the glass meet the requirements. Generally, the edge grinding of glass needs to be ground by coarse, medium and fine grinding wheels first, and then the edge is ground into a frosted surface by a diamond edge grinding wheel. Some also need to be polished with a polishing wheel. If the end surface roughness of the edge of the glass substrate is poor, the edge of the glass substrate will not be smooth enough, and there may be small dark cracks, causing the glass substrate to break. At present, the evaluation method for the end surface roughness of glass substrates is mainly contact probe measurement, and detection is carried out in conjunction with clamping tooling. However, the current clamping tooling has low operating efficiency. How to effectively improve the clamping and detection efficiency has become a technical problem that needs to be solved urgently.
