Glass coating surface defect on-line detection device and defect classification and identification method

Abstract

The invention provides a glass coating surface defect online detection device and a defect classification and identification method, and belongs to the technical field of glass detection. The glass coating surface defect online detection device comprises a line light source module, an imaging module and a terminal data processing module connected with the output end of the imaging module, the width of light emitted by the line light source module is not larger than the thickness of glass, the light emitted by the line light source module forms reflected light after being reflected by the glass, and the terminal data processing module is connected with the output end of the imaging module. The imaging module can receive reflected light reflected by the coated surface of the upper surface of the glass, the reflected light of the lower surface of the glass is arranged outside the receiving range of the imaging module, and the output end of the imaging module judges whether the coated surface of the glass has defects or not according to whether the imaging module can receive the reflected light of the coated surface or not. The device and the method have the beneficial effects that distinguishing detection of a coated surface and a non-coated surface and detection, identification and classification of defects of the coated surface glass are optically solved.

Description

technical field [0001] The invention relates to a glass detection technology structure, in particular to an on-line detection device for glass coating surface defects, and a method for online detection, classification and identification of glass coating surface defects based on the online detection device for glass coating surface defects. Background technique [0002] With the increasing application of glass, the performance requirements of glass are getting higher and higher. In order to meet the performance requirements of special glass, coated glass is more and more widely used. The performance index of coated glass depends not only on the influence of the material of the glass itself, but also on the quality of the coating. Glass has two surfaces. We call the glass surface that needs to be coated as the coated surface, and the other side that does not need coating is called the non-coated surface. Whether the coated surface is flat or not is not only a defect in the mat...
