Description

Technical Field

[0001] The utility model belongs to the field of aging equipment for electronic devices, and in particular relates to a full-automatic static aging equipment for capacitors and lithium batteries. Background Art

[0002] Capacitors and lithium batteries have electrode foil inside. During the production process, they have to go through many complex production processes, which will cause the internal electrode foil, especially the oxide film on the surface of the positive electrode foil, to be damaged to varying degrees. Therefore, the capacitor needs to be aged, that is, the rated aging voltage is applied and aged for a certain period of time in a constant high temperature environment to repair the damaged electrode foil oxide film. Large-diameter capacitors and lithium batteries are currently mostly aged manually due to their large size and high capacity. Workers need to insert capacitors and lithium batteries into special loading racks, put special loading racks into ovens, power on special loading racks, set electrical parameters, and set aging time. These processes need to be completed manually, with low production efficiency, and there are many defective products caused by human factors. These situations bring unnecessary losses to capacitor and lithium battery manufacturers.

[0003] The current aging equipment includes dynamic aging equipment and static aging equipment. In dynamic aging equipment, the loading mechanism inserts capacitors and lithium batteries into a bar frame equipped with a special fixture. After chain conveying, the manipulator grabs the entire bar frame and puts it on the conveying chain of the tunnel furnace. Conductive devices are installed at both ends of the bar frame to connect to each fixture. The bar frame makes intermittent movements in the tunnel furnace. Since it uses contact brush power supply, continuous power supply cannot be achieved. Static aging equipment relies on manual insertion of capacitors and lithium batteries into special fixtures, but manual operation is not only inefficient, but also prone to problems such as loose clamping of aging materials and reverse insertion of electrodes.
