Description

Technical Field

[0001] The present invention relates to the technical field of lens detection, and in particular to a conveniently adjustable lens processing detection device and method. Background Art

[0002] Optical lenses are usually made of one or more optical materials, such as glass, plastic, crystal, etc., and are manufactured and processed using specific processing techniques.

[0003] The preparation process of optical lenses is as follows: raw material preparation, the raw materials of optical lenses are mainly quartz, glass and plastic, etc.; preparation of glass blanks, the glass melting method is to add high-purity raw materials into the furnace for melting, and then pour the molten glass into the mold and wait for it to cool and solidify; processing and forming, putting the glass blank into the processing machine, and processing the glass blank into the required shape and size through processing methods such as rotation, cutting and grinding; grinding and polishing, putting the processed glass blank into the grinding machine for grinding and polishing process; coating, putting the optical lens into the vacuum coating machine, and through the process of heating and evaporation, one or more layers of thin film are coated on the surface of the lens; detection, checking the optical quality, edge clarity and size of the lens to ensure that the lens meets the specifications.

[0004] Optical lenses can be divided into plane lenses, spherical lenses, prisms, cylindrical lenses, etc. according to their shapes. Existing optical lenses are widely used in optical equipment in various fields, such as telescopes, microscopes, cameras, lasers, robots, etc.

[0005] When existing optical lenses are used in optical equipment in various fields, they are not all of a flat and regular lens structure. The lenses may be provided with convex mirrors or concave mirrors according to the application scenarios. The existing optical lens thickness detection devices cannot perform universal thickness detection on regular or irregular optical lenses. Firstly, the existing optical lens thickness detection devices cannot clamp and fix irregular optical lenses well. Secondly, the thickness of the part of the optical lens covered by the clamping component cannot be detected. Therefore, the existing optical lens thickness detection devices cannot perform thickness detection on all positions of regular or irregular optical lenses, which causes detection limitations.

[0006] At the same time, the existing optical lens thickness detection device can usually only clamp one optical lens, and then perform a thickness detection process. After the thickness detection process is completed, the optical lens is removed, the next optical lens is installed and clamped, and then the thickness detection process is performed, and this cycle continues. This will also result in low detection efficiency, the detection process cannot be continuous, and it cannot adapt to the industrial requirements of large-scale optical lens detection, which also causes detection limitations.
