Description

[0001] The utility model relates to the technical field of vacuum coating machines, in particular to a feeding position adjusting device of a coating machine. Background Art

[0002] Vacuum coating machine refers to a type of coating that needs to be carried out under a high vacuum degree. Generally, the film material is heated to evaporate the surface components in the form of atomic groups or ions, and settle on the surface of the substrate to form a thin film through the film forming process. When the vacuum coating machine is coating, the working environment inside the coating machine is a vacuum filling environment. Therefore, the working environment is different from the normal pressure environment, and the working form is relatively special.

[0003] However, when performing coating operations, existing coating machines need to continuously supply coating raw materials into the coating machine. When the coating raw materials are exhausted, the coating machine operation needs to be stopped and the coating machine needs to be adjusted to be in a normal pressure state. Then the coating material is replaced, and then the coating operation continues. It is necessary to stop the machine regularly and replace the raw materials through manual labor, which is time-consuming and labor-intensive, thus affecting the efficiency of coating.
