Metal spraying equipment for metallized film capacitor

Abstract

Metal spraying equipment of a metallized film capacitor comprises a protective cover, a conveying mechanism, a left upper lifting mechanism, a left lower pressing mechanism, an upper metal spraying mechanism, a right lower pressing mechanism, a right upper lifting mechanism, a lower metal spraying mechanism and an ash removing mechanism, and the protective cover is used for forming a dust-free metal spraying environment; and the ash removing mechanism is installed at the inlet end of the protective cover, and the ash removing mechanism is used for removing ash on the surface, needing metal spraying, of a capacitor core. According to the invention, the capacitor core is fixed and moved, and the two sides of the capacitor core are subjected to metal spraying in a vertical simultaneous metal spraying manner, so that the processing efficiency is improved, the metal spraying uniformity is ensured, and the metal spraying surface is not damaged; in addition, a relatively sealed environment is adopted, interference of an external environment is reduced, the capacitor core is moved before metal spraying, meanwhile, ash removal is carried out on the capacitor core, the adhesive force of sprayed materials during metal spraying is improved, and the quality of the capacitor is improved.

Description

technical field [0001] The invention belongs to the technical field of capacitor processing, in particular to gold-spraying equipment for metallized film capacitors. Background technique [0002] Metallized film capacitor is one of the most widely used capacitors. It uses organic plastic film as the medium, metallized film as the electrode, and is made by winding. The film used in metallized film capacitors has polyethylene , polypropylene, polycarbonate, etc.; metallized film capacitors are usually deposited on the surface of polyester film with a metal film instead of metal foil as electrodes during production, because the thickness of the metallized film layer is much smaller than the thickness of the metal foil , so the volume after winding is much smaller than that of metal foil capacitors. At the same time, metallized film capacitors are highly reliable, so they are widely used. [0003] Gold spraying is an important step in the production of metallized film capacitor...

AI Technical Summary

Problems solved by technology

[0003] Gold spraying is an important step in the production of metallized film capacitors. The effect of gold spraying directly affects the quality of capacitors. Most of the existing gold spraying methods are gold spraying when the capacitor core moves through the bottom of the spray gun. Due to the Both sides need to be sprayed with gold, so it is necessary to turn over the capacitor core and pass it through the spray gun again.
