Abstract

The invention discloses a vacuum coating high-speed constant coiling tension apparatus and a control method thereof, and relates to the technical field of film manufacturing technologies. A monitoring device and a control device are arranged on a traditional coating machine, and a system runs a vapor deposition drum linear speed control technology, a vapor deposition drum acceleration process ramp function curve design technology and a coating device constant coiling tension control technology, so fully-automatic process control of uncoiling, vapor deposition and rolling of a film substrate is realized, thereby the problems of large labor intensity, low coating efficiency and low product quality induced by artificial setting of the tension and speed control of film substrates in the prior art and real-time adjustment of the tension and the speed in the coating process by experience are solved, real-time control of the tension and the speed of the system is realized, the production efficiency and the quality of a coating layer are improved, the labor intensity is reduced, and the automatic level of the system is improved.

Description

technical field [0001] The invention relates to the technical field of vacuum coating device control, in particular to a vacuum coating high-speed constant winding tension equipment and a control method. Background technique [0002] With the continuous development of the capacitor film production and manufacturing process, the coating treatment plays an important role in the capacitor film production process. [0003] In the coating process, the vacuum coating device is a commonly used equipment in the coating production line, mainly to coat the film substrate produced by the film drawing line in a vacuum environment. After the coating treatment, the coating thickness, pressure resistance parameters, shrinkage rate, wetting tension, roughness, physical and mechanical properties and other indicators of the film can meet the requirements. Therefore, in the production process of the capacitor film, the coating is an essential process. One of them plays a very important role i...
