Vacuum coating sample table

Abstract

The invention relates to a vacuum coating sample stage, which is designed to ensure uniform coating of all sides of the same sample and uniform coating of samples in different positions of conventional like products. The vacuum coating sample stage is characterized in that a power system of the vacuum coating sample stage comprises a power input shaft, a coupling device, a dynamic sealing device and a motor, wherein the power input shaft and a main shaft of the motor are connected with a central shaft of the dynamic sealing device through the coupling device and fixed on the outer side of a vacuum cavity; a planet gear system comprises a sun gear component and a planet gear component, as well as a planet carrier; the planet gear component comprises a planet gear axle, a gland, a shaft guide sleeve, a bearing, a bearing retaining ring and a planet gear, as well as a gear limiting stop; the sun gear component is fixed on the inner side of the vacuum cavity; the shaft guide sleeve of theplanet gear component is fixed on the planet carrier through the gland; the planet gear of the planet gear component is meshed with a second sun gear of the sun gear component; the sample stage is fixed at the top end of the planet gear axle; and an arc source target material is arranged on the outer side of the vacuum cavity.

Description

technical field [0001] The invention relates to the technical field of vacuum coating in mechanical transmission engineering, in particular to a vacuum coating sample table. Background technique [0002] As an environment-friendly green surface protection technology, vacuum coating is more and more favored by enterprises. Compared with traditional electroplating, chemical plating and other technologies, the key advantage of vacuum coating lies in zero emission and zero pollution during the coating process, but the cost of coating equipment is high, low efficiency, poor uniformity, and it is difficult to achieve industrialization. Common coating samples are fixed on a stationary sample stage and deposited onto the sample surface by target sputtering. For multiple samples at different positions, it is difficult to ensure consistent sample film thickness, especially when depositing multilayer films on different targets. Sex is worse. In order to improve the uniformity, many m...
