Description

Technical Field

[0001] The utility model relates to the technical field of lens placement racks, in particular to a lens placement rack for vacuum coating of optical lenses. Background Art

[0002] Optical glass is made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasound to remove bubbles; then slowly cooled for a long time to prevent the glass block from generating internal stress. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion rate meet the specifications. Qualified glass blocks are heated and forged to form optical lens blanks. After a series of rough grinding, fine grinding and polishing, the optical lens blanks need to be coated. At present, the coating of optical lenses Film operation is a process of placing a lens placement rack in a vacuum coating machine, and under vacuum conditions, evaporating a layer or multiple layers of film on the lens substrate from the evaporation source upwards. During this process, the optical lens needs to be placed on the placement rack. Since traditional placement racks require a support frame to support the optical lens, there will always be a support frame blocking the optical lens, affecting the coating quality of the vacuum coating machine on the optical lens, and traditional placement racks will fix the optical lens through devices such as blocks or clamps to prevent the movement of the optical lens, but the operation of these devices is very troublesome, affecting the coating efficiency of the vacuum coating machine on the optical lens.

[0003] A lens placement rack for vacuum coating of optical lenses disclosed in the Chinese utility model patent application disclosure CN218203040U has the advantages of improving the coating quality of optical lenses by vacuum coating machines and being very convenient to operate. However, the lens placement rack for vacuum coating of optical lenses still has disadvantages: First, during actual use, the horn mouth of the lens placement rack for vacuum coating of optical lenses is perpendicular to the ground, so when the lenses are removed, a large number of lenses may slide off and cause damage; Second, the lens placement rack for vacuum coating of optical lenses uses a horn mouth to adsorb the optical lenses, and an electromagnet to disassemble the optical lenses. During actual use, the service life of this adsorption and disassembly method is short. As the use time increases, the disassembly mechanism may fail to achieve the expected effect due to the reduction of the internal spring effectiveness. Utility Model Content
