Description
Technical Field
[0001] This utility model belongs to the field of metal surface treatment technology, and specifically relates to an automatic coating device in the soft nickel plating process. Background Technology
[0002] The busbar is used to electrically connect battery cells, enabling series and parallel connections. It also performs voltage and temperature sampling, playing a crucial role in battery safety. Busbars in new energy vehicle battery packs and energy storage battery systems, made of copper or aluminum, are classified into rigid busbars, flexible busbars, and flexible-rigid overlap busbars based on their processing methods. The term "busbar" is derived from the English word "bar," a borrowed English word in Chaozhou dialect. It refers to the connection method for battery modules and copper busbar components. A flexible busbar, typically made of copper or aluminum, possesses good flexibility and conductivity. It primarily achieves electrical connections between battery cells through welding or bolting, supporting series and parallel cell connections, and simultaneously performing voltage and temperature sampling, playing a vital role in battery safety.
[0003] However, PVC panels need to have good corrosion resistance and electroplating properties, so a nickel plating process is required. Most existing nickel plating devices use electroplating to coat metal parts with nickel. During the recycling process, metal particles and impurities are generated in the electroplating solution of existing nickel plating devices, and sometimes they stick to the surface of the metal parts. At the same time, most existing electroplating nickel plating devices use a nickel sheet connected to the positive electrode and a metal part connected to the negative electrode for electroplating nickel, resulting in uneven nickel plating thickness. To address this, we propose an automatic coating device for the nickel plating process of PVC panels. Utility Model Content
