Abstract

The invention relates to an aging method applied to processing an aluminum electrolytic capacitor and a device thereof, and provides a preprocessing method of an aluminum electrolytic capacitor before aging and a device thereof. Before aging, a charging process of the aluminum electrolytic capacitor is carried out; the current loaded to the two electrodes of the capacitor is DC current or pulse current, the current value is 30A to 150A; the voltage value is 6.3V to 120V; in the current and voltage, the burr and raw edge produced in material cutting and nail coiling processes of the aluminum electrolytic capacitor can be burned. The device of the invention consists of an anode contact (1), an isolation insulation board (2), a cathode contact (3), a sliding seat (4) of the anode and cathode contacts and a fixed power source (5). When in charge, the device can straighten the bent anode and cathode lines, thereby being conducive to aging and clipping of the capacitor. Therefore, aging speed can be increased and aging efficiency can be improved.

Description

technical field

[0001] The invention relates to a capacitor processing method and equipment, in particular to an aging method and device for processing aluminum electrolytic capacitors. Background technique

[0002] Aging is an important process in the production of aluminum electrolytic capacitors. It refers to artificially imitating the stress conditions such as temperature, voltage, and current that aluminum electrolytic capacitors receive in actual use, and applying these stress conditions to capacitors according to their quality levels. Products with quality risks are allowed to expire early to ensure product reliability. As far as the current production process is concerned, aluminum electrolytic capacitors do not undergo any treatment before aging, which may cause those capacitors that can be completely compensated for by pretreatment as long as they are slightly flawed to be invalid due to aging.
