Problems solved by technology
[0003] At present, most sensors for deviation correction, defect detection, and size detection are set independently, and it is often necessary to provide a backlight source on the other surface of the sheet to be detected relative to the sensor. At the same time, after the sensor and the backlight source are installed separately, the power supply needs to be set separately. wires, which makes the surface defect detection device not only troublesome to disassemble and assemble, but also its wiring is more troublesome, and there are potential problems of interference with other equipment in the installation position and electrical safety

The application discloses a deviation correction, defect and size detection sensor, which is used for deviation correction and detection of surface defects and dimensions of sheet materials. The deflection correction, defect and size detection sensors include a first installation part, a second installation part and a connection part connecting the first installation part and the second installation part. The first installation part and the second installation part are arranged symmetrically, and the connection part is connected to the same side end of the first installation part and the second installation part, forming a C-shaped structure. A first linear image acquisition device is provided on the inner surface of the first installation part close to the second installation part along the length direction relatively close to or away from the connecting part. A first linear light source corresponding to the first linear image acquisition device is disposed on the inner surface of the second installation part. When the sheet passes between the first installation part and the second installation part, the surface defect and size of the sheet can be detected simultaneously, the detection efficiency is high, and the use is convenient.
Description
technical field [0001] The invention relates to the technical field of detection equipment, in particular to a deviation correction, defect and size detection sensor, which is used for deviation correction and detection of surface defects and dimensions of a sheet. Background technique [0002] In the design of machine vision systems, surface defect detection devices based on line-scan cameras have broad application space in battery separators, textiles, papermaking, 3C electronics, and automobiles. With the development of society, customers are no longer only satisfied with the improvement of detection accuracy, but also put forward related requirements for the flexibility and convenience of the detection device. [0003] At present, most sensors for deviation correction, defect detection, and size detection are set independently, and it is often necessary to provide a backlight light source on the other surface of the sheet to be detected opposite to the sensor. At the sam...
