Problems solved by technology

[0004] Based on the existing small-diameter optical lens surface scratch detection, the optical magnifying glass is generally used for magnifying observation. When the optical magnifying glass is moved by this observation method, the line of sight needs to be fixed on the lens, which is likely to cause visual fatigue. At the same time, the detection It is inconvenient to locate each scratch point during the process, resulting in the inability to accurately find the scratch point and repair it after detection. This invention proposes a small-diameter optical lens surface scratch detection device

Abstract

The invention belongs to the technical field of optical lens detection, and particularly relates to a small-diameter optical lens surface scratch detection device. In allusion to the problems that magnification observation is generally carried out through an optical magnifier in the existing small-diameter optical lens surface scratch detection, visual fatigue is easily caused due to the fact that the line of sight needs to stare fixedly at the lens when an optical magnifying lens is moved in the observation mode, and meanwhile, the scratch points cannot be accurately found after detection tobe repaired because positioning of each scratch point is inconvenient in the detection process, the invention proposes the following scheme: the device comprises a bottom plate and an air blowing cylinder. According to the invention, water-absorbing tissue, an air blowing cylinder and an air pump are arranged; when scratch detection is carried out, the optical lens is placed on a vacuum sucker, then the water-absorbing tissue covers the optical lens, then external air is guided into the air blowing cylinder through the air pump, the water-absorbing tissue is compressed through the air outletholes and completely attached to the outer wall of the optical lens, and thus scratches on the optical lens stand out.

Description

technical field [0001] The invention relates to the technical field of optical lens inspection, in particular to a device for detecting scratches on the surface of small-diameter optical lenses. Background technique [0002] The glass originally used to make lenses was ordinary window glass or bumps on wine bottles, shaped like a "crown", from which the name of crown glass or crown glass came from; the glass at that time was extremely uneven and foamy; except In addition to the crown glass, there is another kind of flint glass that contains more lead; around 1790, the Frenchman Pierre-Louis Junard discovered that stirring the glass paste can make glass with a uniform texture; in the production process of small-diameter optical lenses In the process, it is necessary to detect surface scratches by sampling, so a scratch detection device is required. [0003] When detecting scratches on the surface of existing small-diameter optical lenses, the optical magnifying glass is gene...
