白车身四门两盖滚边技术机器人程序及工艺优化方法研究

The Research on Robot Program and Process Optimization Methods of Roller Hemming Technology of Body-in-white Anbauteile

机器人滚边技术在现代白车身四门两盖制造工艺中被广泛使用,而滚边设备损耗、设备自身设计缺陷以及产品零件尺寸更改等因素造成滚边质量的缺陷日益增多[1],从而影响到整车尺寸的匹配和表面质量.通过改变机器人携带滚轮的位置,可以控制零件接触法兰的受力轨迹;通过对滚边程序指令OFFSET的编辑,可以使程序指令更改更加简便和灵活;通过VW USER功能块,可以实时监控并反馈补偿量,自动调节机器人滚轮的施力位置.机器人程序具有简单、直观、柔性的特点,对其中一个或多个不同参数的综合运用,使其相互补偿、相互影响,从而实现对缺陷的改进和优化.

The technology of robot roller hemming has been widely used in the manufacturing process of body-in-white anbauteile.While,depletion and design defects of the roller hemming equipment,part dimension changes and other factors cause more roller hemming quality defects,thereby affecting the vehicle size matching and surface quality.Through changing the roller position with the robot,we can control the force trajectory of the part contacting flange.Through editing the offset command of robot,we can make the program more simple and flexible to change.Through the VW USER function block,it can monitor and feedback compensation in real time,then automatically adjust force position of roller.Robot program has the characteristics of simplicity,intuition,flexibility,and the application of one or several different parameters can play the role of mutual compensation,mutual influence,then to achieve the improvement and optimization of defects.
