Description

Door catch mechanism of vacuum coating machine

Technical Field

The utility model relates to a vacuum coating technical field, especially vacuum coating machine's knocker mechanism.

Background

Vacuum coating is a technique of producing a thin film material by a physical or chemical method, and atoms of the material are extracted from a heating source in a vacuum chamber to hit the surface of an object to be coated. The technology can be used for producing optical lenses, such as navigation telescope lenses and the like; and other functional films, record aluminizing, decorative coating, material surface modification and the like, such as imitation gold coating of watch shells and coating of mechanical cutters, so that the processing hardness is changed. Vacuum coating has three forms, namely evaporation coating, sputtering coating, ion coating and pure ion coating.

The existing vacuum coating equipment generally comprises a chamber body, wherein a door plate is arranged in the chamber body, and when the vacuum coating equipment works, the door plate needs to be ensured to be reliably closed, so that a door catch mechanism is often needed. However, most of the existing door latch mechanisms are closed manually, and the closing force is not large, so that the door latch mechanism is not closed tightly. However, some door latch mechanisms are locked by a cylinder, but due to an unreasonable structure, closing operation is not smooth, and locking force for closing is insufficient.
