A vacuum coating machine

Abstract

The invention provides a vacuum coating machine, belongs to the technical field of machinery, and solves the problem of low production capacity of a conventional vacuum coating machine. The vacuum coating machine comprises a vacuum cover and a vacuum system used for keeping the inside of the vacuum cover in a vacuum state, wherein an umbrella frame and a steaming source are arranged in the vacuum cover; the umbrella frame comprises a rotary plate capable of circumferentially rotating and a plurality of workpiece frames; the workpiece frames are connected with the rotary plate through the first rotary shafts of the workpiece frames respectively and are distributed in an umbrella shape in the circumferential direction of the rotary plate. The vacuum coating machine also comprises a drive mechanism capable of rotating around the central lines of the first rotary shafts while driving the workpiece frames to rotate in the circumferential direction of the rotary plate. According to the vacuum coating machine, a structure that the workpiece frames are distributed in the umbrella shape in the circumferential direction of the rotary plate is adopted, so that the space occupied by the umbrella frame is reduced and the receptor area of the workpiece frames to steaming materials is enlarged; the front and rear surfaces of the workpiece frames are all capable of loading workpieces to be coated, so that the loading quantity of the workpiece frames is increased. The vacuum coating machine is higher in production capacity and better in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a vacuum coating machine. Background technique [0002] With the development of science and technology, the performance of display screens of electronic equipment is continuously improved, and touch screens controlled by direct touch of human hands appear. During actual use, the display screen is easily contaminated with external dust and other dirt, and the touch screen is more likely to leave fingerprints or scratches after being touched. In order to improve the wear resistance and dirt resistance of the display screen, a layer of high wear resistance and anti-fingerprint coating is usually applied on the surface of the display screen by means of vacuum coating. [0003] Vacuum coating is a technology that separates the atoms of the material in the vacuum chamber from the heating source and hits them on the surface of the object to be plated, thereby forming a thin film. The e...

Problems solved by technology

However, the problems of the workpiece three-dimensional rotating bracket of the vacuum coating machine with this structure are: 1. There is still a large space not fully utilized when the rotating bracket revolves, and the production capacity of the workpiece coating can be further improved; 2. The direction of the rotation axis of the rotating bracket The distances between multiple workpieces and the evaporation source are different. The workpieces close to the evaporation source block the workpieces far away from the evaporation source, and the evaporation source needs to provide more coating materials; 3. Whether it is revolution, rotation, or rotation, position the workpiece on the rotating shaft , resulting in different degrees of shaking of the rotating shaft during the rotation process, thereby reducing the uniformity of the film on the surface of the plated workpiece
