前言:
点焊机器人是大众标准中最常使用的基准工艺控制,它涉及到焊接控制,轨迹补偿控制,铣削夹紧控制,电极测量控制.还有虚拟轴软件控制,下面我会一一道来.
基础知识:
机器人使用气伺服焊钳要完成的工作:焊接,更换电极帽,铣削,开关水站RIP
点焊任务应在车辆坐标系(Base)中编程。
对于WPS机器人,电极与带有新E形帽的金属板之间的距离必须为3 mm,入射角必须为90度。SZ在关闭时不得滑动,在焊接时不得引起分流。
焊接点的坐标必须通过示教功能确定。
降压时不能使用示教功能。开口尺寸的计算方法如下:标准开口尺寸SZ +板材厚度+凸台高度。
对于带有补偿系统的焊枪,补偿值以二进制形式传输到焊枪,并且必须在每个焊接点进行编程。夹紧补偿的值应这样确定,使固定电极平缓地放在组件上。夹具补偿的值取决于夹具的类型和焊枪在焊接点的位置。

可以在每个焊接点调用该技术包。通过该调用,一方面根据盖的磨损将TCP临时更改为–X,另一方面根据参数P3“偏移”的值将TCP更改为–X。通过参数P4“距离”,可以选择指定在点PLC处理之后在循环中执行的提升值。这样可以去除以前使用过的组件上的磨痕
中间点或距离大于固定E臂的3mm 焊接点在单步MSTEP模式下编程,无TCP移位且无参数4,因此可以检查或更改固定E臂的编程距离。在单步GO操作中,使用TCP移位和参数4。
