Description

Technical Field

[0001] The present invention relates to the technical field of lens processing, and in particular to a vacuum coating machine for dustproof lens processing and a use method thereof. Background Art

[0002] An optical lens is a transparent material with one or more curved surfaces made of optical materials such as glass or resin, which can refract light along a specific path to form an image. It is widely used in various scenarios that require imaging processing, such as telescopes, cameras, optical processing equipment, and correction of human eye refractive errors. In order to achieve better imaging effects and excellent performance during the use of optical lenses, the operation of covering the surface of the optical lens with a single layer or multiple layers of optical film of a certain thickness by physical and chemical methods is called coating. During coating, the optical lens to be coated is placed in a coating machine. The liquid coating target in the coating machine is evaporated in the form of atomic groups or ions under a heated vacuum state, and settles on the surface of the optical lens to form a thin film through the film forming process.

[0003] In a vacuum coating machine, in order to achieve a high vacuum degree for coating, the gas inside the coating box needs to be extracted. This process is called vacuum extraction and is usually completed by a vacuum pump. When the coating box needs to be opened, the outside air needs to be reintroduced first. This process is called deflation, which is usually done by opening the air valve. During the deflation process, some dust and impurities in the outside air will be introduced into the coating box, which will affect the coating effect and result in a low product qualification rate. Summary of the invention
