Description

Optical lens replacement device for intelligent vacuum evaporation coating monitoring system

Technical Field

The utility model relates to the technical field of optical lenses, in particular to an optical lens replacement device of an intelligent monitoring system for vacuum evaporation coating.

Background

The optical glass is prepared by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and the like according to a specific formula, melting the mixture in a platinum crucible at high temperature, uniformly stirring the mixture by using ultrasonic waves, and removing bubbles; then slowly cooling for a long time to avoid the generation of internal stress of the glass block. The cooled glass block must be measured by optical instruments to verify that the purity, transparency, uniformity, refractive index and dispersion are in specification. The qualified glass blocks are heated and forged to form optical lens blanks, and then the blanks are subjected to a series of optical cold processing, coating, gluing, assembling and the like to finally form qualified products in all aspects such as optical indexes and the like, namely the finally produced optical lenses; then, a plurality of lenses are combined with the die at the optical designed position, and finally, a group of qualified optical lenses is formed. In conventional optical systems, the lens is well defined, i.e. the position in the optical system in which it is located is fixed, and the final optical product is a fixed whole.

The existing optical products are all fixed and integral, such as an industrial camera module, a photographic module, a monitoring camera module, a mobile phone lens, a special environment lens and the like. In the optical industry, most of lens assembly is manually assembled, and when products are assembled and applied to various environments, a certain lens in the lens needs to be replaced after being damaged, and the lens is manually removed, disassembled and replaced. In an optical system, the most vulnerable is the outermost lens, i.e. the lens exposed to the outside in direct contact with the environment throughout the optical system. However, the requirement on the bearing capacity of the outermost lens in the optical system is very high, and in many optical systems, the lens is a plane mirror and only plays an anti-environmental role such as anti-pollution. However, in natural or industrial environments, the lens replacement process is not generally performed, but the entire product, such as a camera, is directly replaced. In a relatively severe environment, the lifetime of the optical lens is very short, especially the last lens. In such a severe environment, the cost of optical lens input is relatively high. In a general environment, the entire optical lens needs to be replaced if the last lens is lost.

The external lens of the optical system in the vacuum evaporation equipment is easy to be dirty and difficult to replace, the external lens of the camera monitoring system in the vacuum evaporation coating process can be influenced by evaporation matters in the production process, and the camera monitoring system is seriously influenced by pollutants on evaporation. Because the production process is in a high vacuum state and cannot be replaced manually, the camera monitoring system cannot meet the working requirement of whole-course real-time monitoring; meanwhile, operations such as optical axis adjustment and focal length calibration of lens installation are complex, when an optical lens is replaced in a precise optical system, complex debugging is needed to ensure the accuracy of the optical system, wherein the optical axis adjustment and focal length calibration usually require manual disassembly of a lens assembly, detection and correction are performed in an externally-lapped optical path, the operation is complex, and the accuracy of the optical system is easy to be reduced due to disassembly and assembly deviation.
