焊接工艺参数化编程的设计与应用

Design and Application of Parametric Programming of Welding Craft

传统的工业机器人在焊接领域的应用主要是根据示教编程器对焊接参数、路径的点位进行手动依次示教而完成的,在面对一些规则但轨迹具有重复性的焊接模型时,传统手动示教效率较低、操作繁琐。针对一种仿α梁盒的焊接应用,结合自主研发的焊接工艺包,设计一套可用于规则模型焊接的可视化参数编程模块,该模块可根据导入模型的关键参数,生成模型样本,通过在样本中选取焊接路径点,生成可直接用于焊接的机器人程序;其中,焊接工艺的相关参数可结合实际通过焊接工艺包进行修改;过渡点可在机器人程序中自由增加;焊接执行中的工作状态可通过模块界面获取并进行监控。该设计可以提高焊接工艺在工作现场的应用效率,简化功能使用的复杂程度,同时保持较高的程序编辑自由度。

The application of traditional industrial robots in the welding field is mainly completed by manually teaching the weld⁃ing parameters and path according to the teach pendent.Traditional teaching program is low efficiency and complex operation when dealing with some regular but repetitive welding models.A visualization programming module which could be used for regular welding was designed.This module was applied forαbeam box welding combined with the independently developed welding craft.This module could generate model samples according to the key parameters of the imported model.By selecting welding path points in the samples,a robot program that could be directly used for welding was generated.The welding parameters could be changed in welding craft.The transition point can be freely modified in the robot program.The welding status could be monitored by user interface.The design can improve the application efficiency of the welding craft in the work filed,simplify the complexity of the function,and provide a high lev⁃el of freedom in program editing.
