Background

At present, with the rapid development of the new energy automobile industry, the driving motor for the new energy automobile gets more and more attention, and the permanent magnet motor is widely applied to the new energy automobile due to the advantages of high power density, high torque density, high efficiency and the like.

The centralized winding is used as a common form of a permanent magnet motor stator, and has the advantage of simple manufacturing process. And the coils after winding are uniformly pressed on the stator core, and all leads are connected with the distribution ring. The distribution ring needs to weld three-phase soft copper bars as an input interface of current and an assembly interface of a customer. The three phases of the stator all need to be welded, and the angle of a welding spot needs to be accurately adjusted during welding.

The existing welding of the distribution ring and the three-phase soft copper plate is mainly in a resistance welding mode, and the resistance welding has the characteristics of high energy utilization rate, environmental protection, relatively low cost and the like. However, the resistance welding electrode and the connecting conductor are bulky and are not easy to move, so that the positioning of the workpiece is a problem which is difficult to solve in the resistance welding process.

In the industry, a three-axis servo limiting mechanism is also mostly adopted to realize the positioning of the stator three-phase soft copper bar. However, the three-axis servo mechanism has high cost, a complex equipment structure, high debugging difficulty and difficulty in large-scale popularization.
