针对钢管防腐涂层厚度不足的问题，研究开发了一种直焊缝涂层厚度补偿装置。该装置利用PLC驱动1台步进电机做定距运动，步进电机通过超越离合器与涂层牵引辊联动，通过牵引辊与涂层膜片之间产生的相对运动改变涂层张力，再使用激光视觉传感器识别焊缝，实现自动补偿，最终达到提高焊缝涂层厚度的目的。通过实际涂覆生产运行，焊缝涂层厚度质量良好，完全达到设计要求。

According to insufficient anticorrosion coating thickness, the coating thickness compensation device for longitudinal weld was developed. The device drives a stepping motor to conduct distance movement by using PLC, the stepping motor realized linkage with coating traction roller through overrunning clutch. The coating tension was changed by relative movement between traction roller and the coating film, and then the weld was identified by the laser vision sensor. It realized automatic compensation, ultimately achieved the goal of improving the coating thickness of weld. Through actual coating production operation, the quality of weld coating thickness is good, and can fully meet the design requirements.
