Abstract

A method of manufacturing a solid aluminum electrolytic capacitor comprises the following steps: (1) core package winding; (2) core package fixing: fixing a positive or negative guide pin of a core package to a fixed bar and placing the core package on a material rack; (3) formation; (4) formation drying: setting the vacuum drying temperature at 150-200 DEG C, and drying the core package for 5-6 minutes in a vacuum environment; (5) impregnation; and (6) polymerization. The step of impregnation includes the following sub-steps: [1] pretreatment agent impregnating; [2] drying I: setting the drying temperature at 60-80 DEG C, and performing drying for 5-6 minutes in a vacuum environment; [3] monomer impregnating; [4] drying II: putting the core package treated in step (3) in a vacuum drying oven, setting the drying temperature at 60-80 DEG C, and drying the core package for 5-6 minutes in a vacuum environment; and [5] oxidant impregnating. The efficiency of capacitor production is high, and produced capacitors are of good quality.

Description

technical field [0001] The invention relates to a manufacturing method of a solid aluminum electrolytic capacitor and processing equipment thereof, in particular to a manufacturing method of a solid aluminum electrolytic capacitor and a vacuum drying oven used therein. Background technique [0002] In the existing production process of solid aluminum electrolytic capacitors, there are three places that need to be dried, namely, after the formation and cleaning, after impregnating the pretreatment agent and after impregnating the monomer. These three drying processes are all dried in a blast oven. The first two The first drying takes 100 minutes, the third drying takes 30 minutes, and takes a total of 230 minutes, which takes a long time, consumes a lot of energy, and has low efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a fast-drying solid aluminum ele...
