摘　　要：研制了一种基于PLC和光学传感器的经济型角焊缝跟踪系统,利用探杆接触被焊角焊缝的边,而光学传感器测量探杆的伸缩,并将信号传递给PLC,通过程序运算跟踪角焊缝的边变化方向和速度,并控制X、Y方向的伺服电机进行补偿,从而保证焊枪的运动轨迹。An economic fillet weld tracking system is developed in this paper applied by PLC and optical sensors.In this system , the edge of fillet weld is set to contact with probe rod.When the probe rod is running, the telescopic state of the probe rod is measured and send to PLC by optical sensors.The PLC calculated the direction and speed of the fillet weld and controll the running of servo motor in X,Y direction based on the program in the PLC, therefore the quality of tracking of fillet weld is assured.
