Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to a double-end bending device for copper busbars. Background Technology

[0002] Copper busbars are important conductive connectors in new energy battery modules, typically used for electrical connections between battery cells and between battery cells and busbars. To adapt to specific installation spaces or meet specific electrical connection paths, the two ends of the copper busbar often need to be precisely bent to form a pre-set structure that meets assembly requirements.

[0003] Currently, the processing benchmarks, clamping positions, and bending dies for copper busbars requiring precise bending at both ends are all designed for copper busbars of fixed length. During production, when the length of the copper busbar changes, in order to ensure the accuracy of the bending position and angle at both ends, it is often necessary to replace the clamping components or bending dies of corresponding specifications. This results in poor adaptability, long switching times for equipment specifications, and impacts production cycle time. Utility Model Content

This provides a highly adaptable copper busbar bending device, thereby avoiding the need to replace the entire device due to changes in the length of the copper busbar, and significantly improving the adaptability and production efficiency of the device.

[0037] In one embodiment, the first bending mechanism 20 includes a first positioning component 21 and a punch 22, wherein: the punch 22 is connected to the first positioning component 21, and the first positioning component 21 is configured to be positioned at a first end of the copper busbar along a first horizontal direction and a second horizontal direction.
