[0002] As we all know, optical lenses are indispensable 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. Optical industrial lenses are widely used in positioning and detecting objects with extremely high reflectivity, such as metal, glass, film, and wafers.

[0003] The existing optical lens assembly positioning device has poor positioning effect and low applicability. Due to the diverse sizes of optical lenses, the positioning components of the device are not easy to adjust in size and cannot be well adapted to optical lenses of different sizes, which leads to easy deviation when assembling the optical lens.
