Description

Technical Field

[0001] The present invention relates to the technical field of new energy motor controller production, in particular to new energy motor controller copper busbar laser welding equipment. Background Art

[0002] During the production process of new energy motor controllers, it is necessary to first weld an L-shaped IGBT-capacitor connecting copper busbar on the assembled semi-finished controller, and then load the L-shaped IGBT-three-phase copper busbar on the IGBT-capacitor connecting copper busbar. The horizontal part of the IGBT-three-phase copper busbar is welded to the horizontal part of the IGBT-capacitor connecting copper busbar, and the vertical part of the IGBT-three-phase copper busbar is welded to the vertical part of the IGBT-capacitor connecting copper busbar.

[0003] The existing GBT-capacitor connection copper busbar welding and IGBT-three-phase copper busbar welding are mostly semi-automatic welding with a low degree of automation, resulting in low welding efficiency. In addition, when welding the IGBT-capacitor connection copper busbar, the IGBT-capacitor connection copper busbar needs to be pressed on the new energy motor controller for welding. When welding the IGBT-three-phase copper busbar, the IGBT-three-phase copper busbar needs to be pressed on the IGBT-capacitor connection copper busbar for welding. The welding process of the copper busbar requires high pressing force. If the force is too great, it is easy to cause damage to the copper busbar. If the force is too light, it is easy to cause cold welding, which affects the normal use of the new energy motor controller and reduces the welding qualification rate of the copper busbar of the new energy motor controller. Summary of the Invention
