Description

TECHNICAL FIELD

[0001] The application relates to a visual detection device, in particular to a coated and uncoated CG glass detection device. BACKGROUND

[0002] CG glass will produce defects (scratches, edge collapse, etc.) in the production and processing process. After processing, the front and back surfaces and the 2.5D surface of each piece of CG glass need to be detected. At present, the detection is mainly manual detection or single machine equipment detection for the detection of one of the surfaces, or only for the detection of coated CG. If automatic detection is to be realized, an important prerequisite is to realize high-speed transmission of CG glass, no secondary pollution during transmission, compatibility of coated and uncoated CG, integrated detection of front and back surfaces and 2.5D surface, adjustability of the visual module, difficulty of switching between different products.

[0003] At present, CG glass detection mainly relies on manual detection and single machine equipment detection. Automatic detection equipment can only detect coated CG glass, and there is no automatic detection equipment that can detect both coated and uncoated CG glass on the market. Manual detection is slow, generally 2 pieces / 30 seconds, and multiple people are needed to detect. The slow speed means high cost, and there is inevitable dirt during transmission. The detection standard is different due to different personal standards. Single machine detection equipment needs multiple machines, occupies more space, and needs manual transmission. Detection generally needs 2 pieces / 10 seconds, and it is not easy to change the configuration when the customer's demand changes. Most of the automatic detection equipment on the market only detects coated CG glass. When uncoated CG glass is detected, it is easy to cause secondary pollution, the yield is unstable and low. In summary, there is a lack of a detection device for coated and uncoated CG glass on the market, which has higher cleanliness, more consistent detection standard, faster switching and is suitable for coated and uncoated CG glass.
