Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a copper busbar welding tool for new energy vehicles. Background Art

[0002] The copper busbar flexible connector is a flexible conductive device for new energy vehicle power batteries. It utilizes the elasticity of a flexible expansion joint to provide protection, preventing switches or busbars from breaking due to short circuits or thermal expansion and contraction. It is also unrestricted in terms of assembly angle. The copper busbar flexible connector is easy to install and highly flexible. Its fast heat dissipation and excellent conductivity make it a popular electrical conductor for lithium-ion battery modules in new energy vehicles. Power batteries consist of multiple cells stacked in series. To increase driving range, new energy electric vehicles require a large number of lithium-ion battery modules. Each module is composed of several battery boxes, resulting in a complex spatial arrangement. To adapt to different working environments, the flexible connector is made of copper foil. Multiple sheets of copper foil are neatly stacked according to the settings, and a polymer diffusion welder is used to weld the overlapping surfaces at both ends of the flexible connector to secure the multiple layers of copper foil.

[0003] For example, the automobile copper busbar welding tool with publication number CN219648924U includes: a base, a slide rail mounted on the upper end of the base, two second vertical rods mounted on the upper end of the slide rail, the middle portions of the two second vertical rods are rotatably connected to a first threaded rod, the exteriors of the two first threaded rods are threadedly connected to first threaded blocks at intervals, two clamps are mounted on the side walls of the two second vertical rods, one end of the two clamps is fixedly connected to the side walls of the two first threaded blocks respectively, two first vertical rods are mounted on the upper end of the base, a cross bar is mounted on the side walls of the two first vertical rods, two mounting plates are mounted on the lower end of the cross bar at intervals, the side walls of the two mounting plates are rotatably connected to a rotating rod, and a welding head is mounted on the exterior of the rotating rod. Through the above structure, the copper busbar remains stable after being clamped to avoid slipping, and the angle of the welding head can be adjusted, thereby ensuring the quality of copper busbar welding.

[0004] The above technical solution has some problems in practical application. During the welding process of the copper busbar, the unwelded part may be deformed due to its own elasticity and other factors, resulting in loose welding in the subsequent welding, affecting the welding quality.

[0005] Therefore, it is necessary to invent a copper busbar welding tool for new energy vehicles to solve the above problems. Utility Model Content
