Description

Technical Field

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

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

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