Description

Technical Field

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

[0002] Vacuum coating is a process that creates thin film materials using physical or chemical methods. Within a vacuum chamber, atoms of the material are separated from a heat source and then impinge upon the surface of the object being coated. This technology can be used to produce optical lenses, such as those for nautical telescopes, as well as other functional thin films, aluminum plating for records, decorative coatings, and surface modification, such as imitation gold plating for watch cases, and coating machine tools to modify machining hardness. There are three types of vacuum coating: evaporation, sputtering, ion plating, and pure ion plating.

[0003] By using vacuum coating technology on the surface of stainless steel plates, the surface properties of stainless steel plates can be improved. When coating stainless steel plates, existing vacuum coating machines basically bend the stainless steel plates and cover them on a rotating rack, and then place the rotating rack in a vacuum container to complete the coating process. During this process, in order to ensure uniform coating, the rotating rack can rotate relative to the vacuum chamber.

[0004] The patent application number CN202321071533.X discloses a vacuum coating rotating frame, which relates to the field of vacuum coating technology and includes a rotating platform, wherein the rotating platform includes a rotating base and an adjustment ring, wherein the rotating base is annular, the adjustment ring is arranged on the inner wall of the rotating base, and the adjustment ring and the rotating base are coaxially distributed; a rotating assembly, wherein the rotating assembly includes a cam splitter, a rotating table, a support rod and an adjustment swivel, wherein the rotating table is arranged on the top of the cam splitter, the support rods are evenly distributed on the top of the rotating table, and the adjustment swivel is arranged on the top of the support rod; a supporting assembly, wherein the supporting assembly includes a supporting table, a stabilizing plate, a power motor and a limiting ring, and the supporting table is evenly circumferentially arranged on the outside of the adjustment swivel. The design of the rotating frame is convenient and practical, can improve the efficiency and quality of vacuum coating processing, and has important application value and promotion significance.

[0005] However, after research, it was found that the above patent still has the following problems: in the above structure, the motor drives the workpiece to be coated to rotate at a uniform speed, and then completes the subsequent uniform coating. However, after the coating is completed, although the rotation of the workpiece to be coated can be stopped by turning off the motor, and then the material can be taken out, the time from the output shaft of the motor being turned off to stopping the rotation is still relatively long, thereby increasing the time for taking out the material and reducing the processing efficiency.

[0006] Based on this, this solution proposes a vacuum coating machine coating workpiece rotating rack. Utility Model Content
