Metal mesh cage film-plating clamping device

Abstract

The invention relates to a metal mesh cage film-plating clamping device, and belongs to the technical field of a vacuum film-plating device. The device is a planetary cylinder-type clamp composed of multiple mesh cages or multiple groups of mesh cages which are arranged side by side along a circumferential direction, each one of the mesh cages is cylindrical or multi-prismatic-type cylindrical, each one of the mesh cages is installed on a horizontal-rotation planetary rotating stand mechanism or on a horizontal-rotation planetary rotating stand mechanism with a two-process self-rotation mechanism by support shafts at two ends of the mesh cage, each one of the mesh cages realizes horizontal revolution once and horizontal autoroatation once or realizes horizontal revolution twice and horizontal autoroatation twice, the size and shape of the mesh cage match the shape and size of a workpiece to be plated with a film so that the workpiece can freely roll in the mesh cage under the gravity, and the length of the mesh cages matches the length of an uniform section of a film-plating zone of a film-plating machine. The metal mesh cage film-plating clamping device has the characteristics of workpiece assembling and unassembling operation convenience and no damage in workpiece film plating, and can be used for film plating processes on a lot of small and medium sized workpieces.

Description

technical field [0001] The invention belongs to the technical field of vacuum coating equipment, in particular to a metal mesh cage coating clamping device for vacuum coating. Background technique [0002] For large quantities of small-sized workpieces, cage barrel plating is generally used in traditional electroplating. That is, it avoids the clamping of a single workpiece, which is time-consuming and laborious; it also avoids the contact points with missing plating on the workpiece. This method is widely used and mature. A similar cage barrel plating method can also be used for vacuum coating. [0003] However, when the size of the workpiece to be plated is relatively large, for example, the size of the workpiece reaches more than 15mm, a large number of workpieces move and roll in the cage, and the workpieces at high places will roll down under the action of gravity, and frequently collide with the workpieces below. Damage the fragile corners and edges of the workpiece....

[0003] However, when the size of the workpiece to be plated is relatively large, for example, the size of the workpiece reaches more than 15mm, a large number of workpieces move and roll in the cage, and the workpieces at high places will roll down under the action of gravity, and frequently collide with the workpieces below. Damage the fragile corners and edges of the workpiece. In addition, the same size cage is used for workpieces of different sizes. Larger size workpieces are more prone to collision damage of workpieces in large size cages.
