Description

Automatic welding system for winding terminals in stator Technical Field The application relates to the technical field of motor production equipment, in particular to an automatic welding system for winding terminals in a stator. Background The stator is used as a core electromagnetic component of a motor (such as a new energy automobile driving motor, an industrial servo motor, a high-efficiency household appliance motor and the like), and can generate an alternating magnetic field to drive the rotor to rotate in the operation process of the motor, so that the high-efficiency conversion of electric energy and mechanical energy is completed. As shown in fig. 1, the stator 1 includes a plurality of winding terminals 11, where the winding terminals 11 are terminals of windings 12 and are distributed in a circumferential array on an end surface of the stator 1. In practical application, adjacent winding terminals 11 need to be electrically conducted through welding to complete phase sequence connection and loop construction of windings 12, so that normal operation of the motor is guaranteed. For example, in the schematic structural diagram shown in fig. 1, it is necessary to weld two adjacent winding terminals 11 in the red frame. The welding quality of the winding terminals 11 has an important influence on the electrical performance, mechanical strength and long-term operation stability of the stator 1. Currently, the welding of the winding terminals 11 is mainly accomplished by semi-automatic welding. In this manner, the stator 1 is usually fed manually, and then adjacent winding terminals 11 in the stator 1 are welded one by a programmable welding device (such as a welding gun). However, since the interval between the adjacent winding terminals 11 in the stator 1 is small and the terminal arrays are densely distributed, a feeding position deviation error easily occurs in the manual feeding process, and thus, problems such as welding position deviation, uneven welding seams, cold joint or missing welding are caused. These defects not only can lead to the reduction of the electrical conduction performance of the stator 1, but also can cause potential safety hazards such as local overheating, short circuit and the like, and seriously affect the overall performance and the operation reliability of the stator 1.
