Research on Centering Location Technology in Automatic Electromagnetic Riveting Based on Industrial Intelligent Camera

针对手工电磁铆接存在的对中性问题,设计了基于工业智能相机的三坐标电磁铆接托架系统,利用工业智能相机对铆接孔进行拍照,并经过图像处理快速计算出孔位中心坐标,最终根据坐标变换转化到装配坐标系中。详细阐述了三坐标铆接托架系统组成、工作原理、控制系统的硬件与软件设计。通过西门子Smart PLC的运动控制功能实现三坐标定位控制,通过WinCC触摸屏建立人机交互界面。进行实际的实施过程,试验结果验证了其系统的定位功能及对中精度的有效性。

Aiming at the neutral problem of manual electromagnetic riveting,a three-coordinate electromagnetic riveting bracket system based on industrial intelligent camera is designed.The riveting holes are photographed by using industrial intelligent camera,and the center coordinates of the holes are rapidly calculated by image processing,finally the result is converted into the assembly coordinate system according to the coordinate transformation.In this paper,the composition,working principle,hardware and software design of the three-coordinate riveting bracket system are described in detail.Siemens smart200PLC motion control function can achieve three coordinate positioning control,and human-computer interaction interface is established by WinCC touch screen.With the actual implementation process,experimental results verify the effectiveness of the positioning function and alignment accuracy of the system.
