Background

In the production process of the soldering lug capacitor, a plurality of complex manufacturing procedures are required, so that oxide films on the surfaces of internal electrode foils (particularly positive electrode foils) are damaged to different degrees, and therefore, the damaged electrode foil oxide films can be repaired by aging the capacitor, namely applying a rated aging voltage and aging for a certain time in a constant high-temperature environment.

Due to the characteristics of large volume, high capacity and the like, the soldering lug capacitor is mainly aged manually at present, the capacitor extension socket frame, the extension socket frame are put into an oven, the extension socket frame is electrified, the electrical parameters are set, and the aging time is set, all the procedures need to be finished manually, the production efficiency is low, the aging effect is poor, a large number of defective products are caused by human factors, and unnecessary loss is caused. The other extreme failure mode is that burrs are generated when the electrode foil is subjected to edge cutting, electrolyte or electrolytic paper contains impurities, so that the burrs and the tips of the electrode foil discharge to generate an implosion phenomenon in the charging process of the capacitor, the explosion is generated due to the bad effect, and a shell is cracked to cause fire; if the internal explosion occurs, the housing bulges or the appearance has no obvious change, and the general detection means can not detect the explosion, so that the explosion can be regarded as qualified products to flow into the client, which causes serious quality problems and great loss to the client.
