Abstract

The invention discloses an optical detection imaging system. The system adopts a multi-angle combined light source to perform high-precision and full-automatic detection on cover plate glass, particularly on cover plate glass of a mobile phone. The multi-angle combined light source is designed for the diversity of appearance defects of the cover plate glass of the mobile phone. An angle, a position and a wavelength of each light source in the combined light source are all optional to adapt to different defect detections; each light source in the combined light source can be subjected to strobing control by a strobing controller. The system realizes a design with a high integration degree through the strobing of the light source, is compact and stable in layout structure and convenient to adjust, and can be used for full-automatic detection for the appearance of the cover plate glass.

Description

technical field [0001] The present invention relates to an imaging system for the appearance detection of cover glass (CG, Cover Glass), more particularly, it is an imaging system aimed at the appearance quality of cover glass, especially mobile phone cover glass (whether it contains scratches, edge chipping or not). , point defects, etc.) optical inspection imaging system for high-efficiency, fully automatic inspection. Background technique [0002] At present, most of the cover glass commonly used in the market, especially the mobile phone cover glass, is inspected manually. In a dark room and dust-free environment, human eyes can judge whether the appearance of the mobile phone cover glass is qualified under specific lighting conditions. Manual detection has certain advantages, because the human eye is currently the most sophisticated optical imaging system in the world, and it has great flexibility. However, manual detection also has great disadvantages, such as low dete...
