薄板激光焊机激光梁位置伺服系统

摘要

介绍了冷轧薄板生产线LW21L激光焊机激光梁位置伺服控制系统的相关工艺和控制方法.该位置伺服系统采用SIMODRIVE 611U变频、1FK7交流同步伺服电机和旋转编码器等电器.根据焊接工艺需要伺服系统的定位方式设置为手动控制和自动控制两种,定位系统设置为相对位置定位系统和绝对位置定位系统.采用PROFIBUS通信,保证了参数的快速、准确传递.该系统实现了切割光头和焊接光头的精确定位以及速度的闭环控制.%Technological process of servo system and control system for laser beam of LW21L type laser welder in cold rolled plate production line were introduced. Siemens SIMODR1VE 611U inverter, 1FK7 ac synchronous servo motor and revolving encoder were adopted in the control system. Manual localization way for the servo control system was set as manual control and automatic control, positioning system was set as relative positioning system and absolute positioning system according to the welding process. PROFIBUS was adopted to communicate,to ensure the parameters of the rapid and accurate transfer. This system realizes the cutting baldheaded and welding baldheaded of accurate location and speed closed-loop control.
