Abstract

The invention relates to a manufacturing method for an aluminum electrolytic capacitor. The manufacturing method comprises the processes of cutting, riveting and coiling, impregnating, assembling and aging, wherein the aging process comprises the steps of carrying out normal-temperature aging on the assembled product, and gradually increasing voltage through multiple sections of voltage-boosting processes which are implemented at intervals in time sequence; carrying out high-temperature aging, and gradually increasing temperature through multiple sections of temperature-increasing processes which are implemented at intervals in time sequence, wherein damaged oxide films generated in the processes of cutting, riveting and coiling and the like can be repaired by the normal-temperature aging process; the oxide films can be subjected to crystal form conversion and can be stabilized by the high-temperature aging process; the stability of the product in the voltage-boosting process can be improved by the normal-temperature aging process; the condition of protrusion or explosion of the product caused by one-time direct temperature increasing can be avoided due to the high-temperature aging process; and the performance of the product can be detected in time after each section of the temperature-increasing process is completed so as to detect unqualified products in each stage in advance in order to improve the process.

Description

technical field [0001] The invention relates to the technical field of aluminum electrolytic capacitors, in particular to a manufacturing method of aluminum electrolytic capacitors. Background technique [0002] Aluminum electrolytic capacitor is a general-purpose electrolytic capacitor made of aluminum material with good electrical performance, wide application range and high reliability. The production process of traditional aluminum electrolytic capacitors usually includes cutting, nailing, impregnation, aging, sorting, assembly, packaging and other processes, so the manufacturing process determines the quality of aluminum electrolytic capacitors. [0003] However, due to the limitations of the manufacturing process, the traditional aluminum electrolytic capacitors have many limitations in use, unstable performance, and easy to cause defects. Contents of the invention [0004] Based on this, it is necessary to provide a method for manufacturing an aluminum electrolytic...
