Description

Technical Field

[0001] The invention belongs to the field of glass substrate detection, and in particular relates to a glass substrate surface roughness measuring instrument. 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 roughness of the end surface of the glass substrate is mainly the probe measurement of the roughness sensor, and the detection is carried out in conjunction with the clamping tooling. However, when the glass substrate is fixed, the posture of the surface to be measured cannot be guaranteed to be uniform, so the posture of the roughness sensor needs to be adjusted. How to make the posture adjustment of the roughness sensor applicable to any scenario has become a technical problem that needs to be solved urgently. Summary of the invention
