基于西门子PLC的激光焊接装备控制系统设计

Design of laser welding equipment control system based on SIEMENS PLC

目前国内激光焊接设备普遍采用基于嵌入式板卡的控制方法,具有稳定性低、多轴联动效果较差等缺点。设计了基于西门子PLC的高稳定性、高精度的标准激光焊接设备控制系统,突破了任意平面插补曲线的编译和导入等关键技术,实现任意两轴间的直线和圆弧插补运动控制,具备任意曲线文件导入解析以及G代码在线编译功能,满足装备加工需求。

At present,domestic laser welding equipment generally uses embedded board-based control methods,which have the disadvantages of low stability and poor multi-axis linkage effects. This paper designs a standard laser welding equipment control system based on Siemens PLC with high stability and high accuracy. It breaks through key technologies such as the compilation and import of arbitrary plane interpolation curves,realizes linear and circular interpolation motion control between any two axes,and has the functions of importing and analyzing arbitrary curve files and G code online compilation to meet the equipment processing requirements.
