Description

Technical Field

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

[0002] Vacuum coating is a technology that produces thin film materials by physical methods. In a vacuum chamber, the atoms of the material are separated from the heating source and hit the surface of the object to be plated. In the production process of silica crystal mirrors, in order to improve the efficiency of coating, vacuum coating is required. In addition, in order to perform double-sided coating during the coating process, the silica crystal mirror needs to be flipped using a flipping mechanism during the coating process.

[0003] For example, the utility model with application number 202120507844.0 discloses an automatic flipping mechanism for an optical coating machine. The acceleration gear and the reduction gear are set to facilitate the flipping of the adjustment device, and the small flipping angle can be adjusted to make the flipping angle more precise. The three sets of clamps can clamp the object to be coated at three points at the same time. The structure is simple and can facilitate the precise adjustment of the rotation angle, thereby improving the processing quality and making the clamping more stable.

[0004] Similar to the above applications, there are still some shortcomings.

[0005] During use, only the vertical surface can be flipped to adjust the coating surface, and the horizontal rotation of the coating object cannot be controlled during the coating process, which easily leads to uneven coating.

[0006] Therefore, a vacuum coating flipping mechanism is designed to optimize the above problems.

[0007] Based on this, this scheme proposes a rotating mechanism for a vacuum coating machine. Utility Model Content
