摘要
针对埋弧焊多道焊的焊缝跟踪以及焊枪高度跟踪问题,设计了一种二维跟踪系统。焊缝跟踪采用视频摄像传感器作为检测元件,实时检测坡口的棱边,视频信号经处理后送入主要由单片机构成的偏差计算与处理电路,驱动焊缝纠偏轴电机进行焊缝的实时纠偏。焊枪高度跟踪采用高度位移传感器,实时检测工件高度,检测信号经A/D转换、单片机偏差计算,驱动焊枪高度轴电机进行焊枪高度的实时纠偏。
Regarding to submerged arc weld multi-pass weld track and height of weld gun,two-dimension track system is designed.Weld track system adopts video camera sensor as inspection item to inspect bevel timely,and video signal processed is transmitted into bias calculation and process circuit made of single PC and then weld mis-alignment correction motor shall be driven to correct weld alignment timely.Height track system of weld gun adopts height displacements sensor to time inspect the height of work part,and inspected signal after A/D transferred and signal PC bias calculation is used to drive axis motor to adjust height of weld gun.
