Fast impregnation method for capacitor core package and device thereof

Abstract

The invention discloses a fast impregnation method for a capacitor core package. The method comprises the following steps of putting the core package required to be impregnated into an impregnation tank, and sealing the impregnation tank; opening a liquid storing barrel, pouring the impregnation liquid into the liquid storing barrel; vacuumizing the impregnation tank through a vacuum constant pressure device; during vacuumizing, extracting moisture and air in the core package of the capacitor at the same time; injecting the impregnation liquid from the liquid storing barrel in the impregnation tank in a vacuum state; immersing the core package of the capacitor in the impregnation liquid, fast penetrating the impregnation liquid in the core package of the capacitor to be impregnated by the vacuum state in the impregnation tank, keeping the vacuum state in the impregnation tank; releasing the vacuum state in the impregnation tank instantaneously to be normal atmosphere, and penetrating the impregnation liquid in the core package of the capacitor to be impregnated by the atmospheric pressure. The invention further discloses a device for implementing the method. The method and device provided by the invention has the advantages of short impregnation time, high efficiency, good impregnation quality and low energy consumption.

Description

technical field

[0001] The invention relates to the field of production and manufacture of capacitors, supercapacitors and aluminum ion batteries, in particular to a rapid impregnation method for capacitor core packs and a device for implementing the method. Background technique

[0002] Core packs are one of the main components in capacitors, supercapacitors and aluminum-ion batteries. Consists of positive foil, negative foil, paper and guide pins or foil strip staples. Previously the core of the capacitor contained the dipping method was. Put the core package into the container containing the impregnation liquid and soak for a long time, so that the impregnation liquid penetrates into the positive foil, negative foil and paper, and penetrates into every part of the entire core package. Such soaking method has low production efficiency, inconsistent impregnation effect and unstable quality. After soaking, the liquid on the surface of the core package is dried by a drier,...
