Description

Technical Field

[0001] The utility model relates to the field of optical glass processing equipment, in particular to a clamping device for double-sided vacuum coating of large-size optical glass. Background Art

[0002] Large-size optical glass refers to optical glass with larger sizes, which is usually used to manufacture high-end equipment, such as large telescopes, satellite communications, lasers, etc. Its characteristics include large size, high precision requirements, stable physical properties, high mechanical strength, long production cycle and high cost. The manufacture of large-size optical glass requires high-precision technology and equipment to ensure its quality and stability. In the existing process of processing large-size optical glass, large-size optical glass needs to be double-sided vacuum coated.

[0003] The existing equipment for double-sided vacuum coating of large-sized optical glass generally includes a coating tank, a heating component, and a heating assembly. The large-sized optical glass to be coated is placed in the coating tank, and the coating tank is then evacuated by an external vacuum device. After the vacuum is completed, the heating assembly heats the internal placement box, and a target material is arranged inside the placement box. The target material is separated into atomic groups by the heating assembly, and the atomic groups are transported to the coating tank through a pipeline, and fall on the double-sided large-sized optical glass to form a film layer. After the film layer is formed, the coating work for the large-sized optical glass is completed, and the large-sized optical glass with the newly formed film layer is Glass is not easy to come into contact with water, and the air in the coating tank has a certain temperature. It is very easy to form water droplets after contacting with the outside air, and come into contact with the quartz crystal resonator that has just formed a film layer. To avoid this situation, a heater is set on one side of the coating tank to heat the air entering the coating tank, so as to reduce the formation of water droplets in the coating tank. Then, when the temperature in the coating tank is completely lowered, the large-size optical glass can be taken out. However, in the existing coating process, the large-size optical glass is directly placed inside the coating tank.
