激光寻位技术在商用车仪表板横梁焊接上的应用

Application of Laser Position Identification Technology in Welding of Commercial Vehicle’s Instrument Panel Cross Beam

某仪表板横梁采用自动化焊接,为消除焊缝位置偏移对焊接质量的影响,需要探究焊缝跟踪的控制方法及应用。研究和对比了几种常用焊缝跟踪的控制方式,将激光寻位技术在某商用车仪表板横梁自动焊接上实现应用,从方案设计、系统架构、工作过程、使用效果等方面进行了阐述。经实际生产验证,激光寻位技术有效实现了对焊缝的跟踪定位,通过反馈和纠正焊接机器人运动轨迹,提高了仪表板横梁焊接精度,为提升驾驶室内饰装配质量提供了有力保证。

A cross beam of instrument cluster was welded automatically.In order to eliminate the influence of weld seam position deviation on welding quality,it is necessary to explore the control method and application of weld seam tracking.Several common control methods of welding seam tracking were studied and compared,laser position identification technology was applied in the automatic welding of commercial vehicle’s instrument panel cross beam.The scheme design,system architecture,working process,using effect and other aspects were expounded in detail.Through the verification of the actual production,the laser position identification technology effectively realized the tracking and positioning of the welding seam.By giving feedback and correcting the movement trajectory of the welding robot,it improved the welding accuracy of the instrument panel cross beam,and provided strong guarantee for improving the assembly quality of the cab interior.
