Metal film evaporation equipment for film capacitor processing

Abstract

The invention relates to capacitor processing equipment, and provides metal thin film evaporation equipment for processing a thin film capacitor. The equipment aims to solve the problems that when a traditional evaporation device is used for evaporation of a thin film, an evaporation source is uniformly heated, the evaporation thickness is not uniform, layering is not uniform, the evaporation efficiency is low and the production efficiency of the thin film capacitor is affected. The equipment comprises an outer box, a plurality of supporting legs arranged at the lower end of the outer box anda box door arranged on the front wall of the outer box, and a vacuumizing machine is arranged at the upper end of the outer box. A vacuumizing pipe is arranged at the input end of the vacuumizing machine, and the lower end of the vacuumizing pipe extends to the lower part of an inner cavity of the outer box. A thin film roll is arranged in the inner cavity of the outer box, and a thin film is wound on the thin film roll. The other end of the thin film sequentially passes through a cleaning assembly, two steering rollers and a cooling assembly and is wound on a film winding roller. The equipment is especially suitable for high-efficiency evaporation processing of the metallized thin film, and has relatively high commercial prospects.

Description

technical field [0001] The invention relates to the technical field of capacitor processing equipment, in particular to metal film evaporation equipment for film capacitor processing. Background technique [0002] Metallized film is used as the core group material in film capacitors, including ordinary metallized film and metallized safety film. Evaporation is a method of heating the material in a vacuum environment to vaporize it and deposit it on the substrate to obtain a thin film material , also known as vacuum evaporation or vacuum coating. [0003] The existing film capacitors need to vapor-deposit the internal film to form a metallized film during processing, so as to ensure that the characteristics of the film meet the production requirements of the film capacitor. The uneven heating of the evaporation source will lead to inconsistent thickness and uneven layer of evaporation, which will cause safety and quality problems of film capacitors. On the other hand, the ev...
