Abstract

The invention relates to a glass edge defect detection method which comprises the following steps: placing glass in parallel, and spacing two adjacent pieces of glass by adopting a spacer to form a glass stacking column; conveying the glass stacking column to a darkroom, wherein light irradiates one side of the glass stacking column and penetrates through the glass stacking column; and observing the glass stacking column from the side, away from the light irradiation end, of the glass stacking column, determining whether defects exist or not, if the defects exist, the position of the glass with the defects is determined according to the glass stacking column, and if the defects do not exist, detecting the glass to be qualified. The method for detecting the glass edge defects can effectively detect the glass edge defects, cannot miss small-size defects, improves the product quality, and is very convenient to operate.

Description

technical field [0001] The present disclosure relates to the technical field of glass detection, and in particular, to a detection method for glass edge defects. Background technique [0002] Glass needs to be cut and ground during processing. When the production line is abnormal, edge defects such as cut pieces, micro-cracks, undergrinding, and burnt edges are prone to occur, and such defects need to be inspected. [0003] At present, direct detection with human eyes is used, but due to the small size of such defects, it is difficult to find, and it is easy to miss detection, resulting in product quality problems. Contents of the invention [0004] The purpose of the present disclosure is to provide a detection method for glass edge defects, which can effectively detect glass edge defects without missing small-sized defects, improves product quality, and is very convenient to operate. [0005] In order to achieve the above purpose, the present disclosure provides a metho...
