Description

Semi-automatic glass polisher and glass polishing method

Technical Field

The invention relates to the technical field of glass processing equipment, in particular to a semi-automatic glass grinding machine and a glass grinding method.

Background

The TFT-LCD thinning is generally carried out by adopting a chemical thinning method at present, and for the TFT-LCD with the size of more than G5.5, one cutting is generally required before thinning. Glass chips generated by cutting generate invisible fine defects on the surface of a product under a common fluorescent lamp in the later logistics process, the defects can preferentially react with etching acid liquor in the thinning process, and the defects can be further amplified after being corroded. In order to improve the TFT-LCD thinning appearance yield, the amplified defects are required to be repaired by polishing. These appearance defects vary in degree of damage, and also in position, size of the formed defect, and depth after the completion of thinning. The existing single-side polishing machine cannot meet the polishing requirement of a single-point/local range, so that the surface defects with different apparent sizes and uneven distribution cannot be completely removed by one-time polishing.
