[0002] Optical lenses are essential components in machine vision systems, which directly affect the quality of imaging and the implementation and effect of algorithms. Optical lenses can be divided into short-focus lenses, medium-focus lenses, and long-focus lenses based on focal length; wide-angle, standard, and telephoto lenses based on field of view; and fixed-aperture fixed-focus lenses, manual-aperture fixed-focus lenses, automatic-aperture fixed-focus lenses, manual-zoom lenses, automatic-zoom lenses, automatic-aperture electric-zoom lenses, and electric three-variable (aperture, focal length, and focus are all variable) lenses based on structure. During the production process of the lens barrel, the burrs on the surface of the lens barrel need to be polished to ensure its smoothness and facilitate the subsequent installation and use of lenses. The existing optical lens barrel deburring device cannot grind lens barrels of different diameters during the grinding process of the lens barrel.

[0044] The left and right ends of the placing table 101 are provided with blowers. When the blower provided on the placing table 101 is started, the debris generated after the polishing part 124 polishes the surface of the lens barrel can be blown into the waste chip groove 120, so that the waste chip groove 120 can collect the debris.

[0045] Further optimization is performed, a buffer layer is provided on the side of the fixing plate 111 that contacts the inner wall of the lens barrel. The buffer layer is made of rubber material, and the fixing plate 111 can avoid damaging the inner wall of the lens barrel when contacting the inner wall of the lens barrel by providing the buffer layer, and the friction force generated when the fixing plate 111 and the inner wall of the lens barrel move relative to each other after the buffer layer is provided is increased, which can further improve the fixing effect of the fixing plate 111 on the lens barrel.
