Abstract

The invention relates to the technical field of metallized film evaporation, in particular to an efficient evaporation device for a metallized film. An evaporation chamber is arranged on a workbench, a vacuum system is externally connected with the evaporation chamber, a conveying mechanism for conveying a film base material and an isolation mechanism for shielding an area, which does not need to be coated, of the film base material are arranged in the evaporation chamber, the isolation mechanism is located below the conveying mechanism, and a lower tungsten filament assembly and an upper tungsten filament assembly are arranged in the evaporation chamber. By using the efficient evaporation device for the metallized film, evaporation metal scraps are placed in a cavity formed by the lower tungsten filament assembly and the upper tungsten filament assembly, internal metal materials roll due to the rotating lower tungsten filament assembly and the rotating upper tungsten filament assembly, and the evaporation metal scraps make full contact with the heating tungsten filaments, so that the metal melting rate is increased, and then the evaporation efficiency is improved; and the upper tungsten filament assembly is controlled to be rotationally opened or closed through an angle adjusting mechanism, and the heating and evaporation requirements of evaporated metal are met.

Description

technical field [0001] The invention relates to the technical field of vapor deposition of metallized films, in particular to a high-efficiency vapor deposition device for metallized films. Background technique [0002] A capacitor is a device that holds charges and consists of two conductors that are close to each other with a layer of non-conductive insulating medium in between. Film capacitor is a kind of capacitor, which is a capacitor with excellent performance. It has the characteristics of non-polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), and small dielectric loss. It is widely used in analog circuits. [0003] A common film capacitor is made by winding metal foils such as aluminum as electrodes and overlapping plastic films. However, there is another manufacturing method for film capacitors, called metallized film, which is made by vacuum-evaporating a thin layer of metal on a plastic film as an electrode. [...
