摘　　要：针对逆变交流电阻焊设备在焊接新能源汽车电机定子时,存在的焊接精度不稳定、焊接后产品一致性差等问题,设计一种智能化焊接监控系统。该系统以西门子PLC为控制核心,包括硬件监控电路和控制软件。系统采用基于端子厚度为主、焊接时间为辅的方案提高焊接精度和一致性;采用基于MODBUS总线与焊接电源通讯,智能记录焊接数据。实测结果证明了该系统可提高焊接精度与焊接一致性,并实现了电机焊接的可追溯性,提高了生产车间的智能化程度。There are problems such as unstable welding precision and poor product consistency for the inverter AC resistance welding equipment to weld the new energy vehicle motor stator.In order to solve those problems,an intelligent welding monitoring system was designed.The system used Siemens PLC as the control core,including hardware monitoring circuits and control software.It adopted the scheme based on the terminal thickness and the welding time as the supplement to improve the welding precision and consistency.The MODBUS bus was used to communicate with the welding power source to intelligently record the welding data.The measured results show that the system can improve the welding precision and welding consistency,and realize the traceability of the motor welding which improves the intelligence of the production workshop.
