Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to a copper busbar shaping mechanism. Background Technology

[0002] As a key structural component in new energy batteries, copper busbars are mainly used for electrical connections between terminals, busbars, and battery modules. To improve the insulation and mechanical protection performance of copper busbars, an insulating heat-shrink sleeve is usually fitted over them. After the heat-shrink sleeve is fitted, it is heated by a heating device to shrink and fit tightly against a predetermined position on the surface of the copper busbar body, thus meeting the insulation and protection requirements.

[0003] After the copper busbar is bonded to the heat shrink sleeve, it needs to be bent and shaped according to the requirements of the installation space or connection method to form the preset structural shape. However, during the shaping process, the copper busbar will generate large mechanical stress at the bending part. If the friction and support force acting on the heat shrink sleeve are insufficient, the heat shrink sleeve may shift along the surface of the copper busbar body, causing its insulation position to be misaligned, which in turn affects the electrical performance and safety.

[0034] Specifically, the fixed module 21 is fixedly mounted on the boss 27 by the threaded assembly 28, and the boss 27 is mounted on the base 10 by the threaded assembly 28, so that the fixed module 21 and the corresponding moving module are kept on the same horizontal plane.

[0044] The combination of air source 70 and air blowing pipe 71 assists in cooling the copper busbar and heat shrink sleeve during the bending process, which helps the heat shrink sleeve to be quickly shaped and improves the product processing quality.

[0045] The working principle of the above-mentioned copper busbar shaping mechanism is as follows: S1, the positioning post 62 passes through the positioning hole to position the first end of the copper busbar at the first pressure plate 40, and the first driving assembly 30 drives the second pressure plate 50 to approach the pressure bearing surface 41 so that the copper busbar body and heat shrink sleeve at the preset position are pressed against the pressure bearing surface 41 through the pressure application surface.
