Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a vacuum coating clamp. Background Art

[0002] Vacuum coating machine mainly refers to a type of coating that needs to be carried out under a higher vacuum degree. There are many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition and many other types. The main idea is to divide it into two types: evaporation and sputtering. Evaporation coating generally heats the target material to evaporate the surface components in the form of atomic groups or ions, and precipitates on the surface of the substrate to form a thin film. For sputtering coating, it can be simply understood as bombarding the target material with electrons or high-energy lasers, and sputtering the surface components in the form of atomic groups or ions, and finally depositing on the surface of the substrate, undergoing a film-forming process, and finally forming a thin film.

When clamping workpieces of different specifications, the corresponding fixture needs to be replaced frequently, which is very inconvenient. At the same time, the contact area with the coating surface of the workpiece such as the can is large, which affects the coating effect and has certain limitations when used. Utility Model Content

The whole process has many steps and low efficiency, which reduces the cleanliness of the coating on the workpiece surface. In this regard, the utility model adopts an automatic flipping device, in which a gear is fixed on the surface of the connecting rod. The cylinder is turned on to drive the piston rod to move, and the piston rod drives the slider to move in the first slide groove, so that the tooth groove at the bottom of the slider drives the gear to rotate, thereby driving the connecting rod to rotate and flipping the fixture to achieve the purpose of automatic flipping.
