Description

Technical Field

[0001] The utility model relates to the technical field of dip molding equipment, in particular to an automatic dip molding equipment for a busbar of a new energy battery. Background Technique

[0002] The busbar of a new energy battery is a conductive structure used to transmit electric energy in an electric vehicle. It is usually designed to be flat and made of a metal with high electrical conductivity such as copper or aluminum. It not only is responsible for transmitting electric energy from the battery pack to the motor or other electrical equipment, but also plays multiple roles such as current collection, distribution, electrical connection, and thermal management. During the production process of the busbar of a new energy battery, dip molding equipment is needed to perform dip molding treatment on the busbar;

[0003] For example, the authorized patent with the publication number of CN208853143U (a copper bar dip molding device): includes a dip molding barrel and two rotors arranged opposite to each other.
