Description

Technical Field

[0001] The utility model relates to the technical field of vacuum coating machines, in particular to a workpiece rotating mechanism of a vacuum coating machine. Background Art

[0002] Vacuum coating refers to coating under a relatively high vacuum degree. There are many types of coating, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, etc. The main idea is to divide it into evaporation and sputtering.

[0003] For evaporation coating, the target material is generally heated to evaporate the surface components in the form of atomic groups or ions, and settle on the surface of the substrate (or workpiece), forming a thin film through the film forming process. The thickness uniformity and component uniformity mainly depend on: the lattice matching degree between the workpiece material and the target material; the workpiece surface temperature; the target evaporation power and rate; the coating vacuum degree; the coating time and thickness. After adjusting the workpiece coating temperature and vacuum degree, as well as the target evaporation conditions, it is necessary to continuously convert the coating workpiece position according to the specific requirements of the workpiece through a reasonably set transmission mechanism to ensure the workpiece coating quality, which is especially important for large workpieces such as automobile wheels.
