[0002] Vacuum coating is a coating technology that uses physical methods in a vacuum environment to vaporize the surface of the material source into gaseous atoms, molecules or partially ionize them into ions, and deposits them on the surface of the substrate through low-pressure gas. It is mainly divided into evaporation deposition coating and sputtering deposition coating.

[0003] The existing vacuum coating machine drives several brackets to rotate through a planetary structure. The outer side of the bracket is used to install a connecting frame connected to the product to be coated. Different connecting frames need to be configured for different products. The connecting frame and the bracket are fixed with screws. When replacing the connecting frame, it is necessary to disassemble and assemble the connecting frame one by one in the coating machine. The operating space is narrow and cannot be prepared in advance. It can only be replaced in the coating machine, which is time-consuming and cannot meet the usage requirements.

[0026] Rotate the upper end plate, use the upper bolt to pass through the upper through hole and connect it with the upper nut, limit the hanging rod, and rotate the hanging rod to cooperate with the circular groove. Then push the upper thrust bearing to the upper sinking platform, move the upper sleeve, and the upper support plate outside the upper sleeve abuts against the upper thrust ball bearing. Use the upper tightening bolt to tighten the hanging rod to achieve relative fixation of the upper sleeve and the hanging rod, and complete the upper end installation.
