Manufacturing method of cam drive feeding mechanism

The utility model relates to the technical field of vacuum coating, specifically a cam drive feeding mechanism.

Background technique:

2. As we all know, as long as a layer of film is coated on the surface of certain materials, the material can have many new and good physical and chemical properties. Vacuum coating is to evaporate or evaporate metals, alloys or compounds in a vacuum. Sputtering to make it solidify and deposit on the coated object (called substrate, substrate or base).

3. The current vacuum coating machine is equipped with a crucible assembly, and the sio2 ring in the feeding assembly is fed into the crucible assembly during operation, so it is necessary to set up a corresponding feeding mechanism to send the sio2 ring into the crucible mechanism.

4. Although the current feeding mechanism can feed materials, it needs to be equipped with a corresponding driving mechanism and corresponding program control to ensure that the sio2 ring is stably fed in with the rotation of the crucible assembly, the structure is complicated, and the cost is high.
