Welding control system and control method thereof

Abstract

The invention discloses a welding control system and a control method thereof, the first image acquisition module, the second image acquisition module, the first welding workbench clamping sensor, the second welding workbench clamping sensor, the welding workbench distance The sensor and the welding table moving motor control button are respectively connected to the input port of the PLC; the welding detection camera is connected to the weld image processing module, and then the weld image processing module is connected to the input port of the PLC; one end of the welding robot control system is connected to the PLC , the other end is connected to the main body of the robot; the first contactor coil, the second contactor coil, the third contactor coil and the fourth contactor coil are connected to the output end of the PLC. The control system can automatically identify the workpiece type, thereby automatically selecting the processing program, and can automatically detect the welding quality. The control method of the control system can reduce processing time and reduce the standby time of the welding torch.

Description

technical field [0001] The invention relates to a welding control system and a control method thereof. Background technique [0002] Welding robots are commonly used in automobile production lines to replace manual welding, which can save a lot of manpower and can work 24 hours a day. However, the commonly used welding robot control system still has certain defects in practice. When welding different workpieces, it is necessary to manually select the welding program. The detection of weld quality is affected by human factors, and the control process is single, which will make the welding torch stand by. state, waste of welding time and other issues. Contents of the invention [0003] The purpose of the present invention is to: aim at the above existing problems, provide a welding control system and its control method, the control system can automatically identify the type of workpiece, thereby automatically select the welding program, can automatically detect the welding ...
