基于PLC位控单元的点焊控制系统设计

System design for controlling spot welding based on PLC position control unit

点焊在工业领域中应用的非常广泛。针对点焊过程中从一个焊点到另一个焊点的快速、精确地运行控制,这里利用PLC位控单元的控制系统,用步进电机驱动点焊电极,经过实际应用,实现了对点焊焊点位置的高效、准确和精密控制。

Spot welding technology has been USed widely in various industry fie lds.The rapid and accurate control for the spot welding process from one site to another is very important.with the application of PLC position control unit in the electrode motion process driven by stepping motor the effective,accurate an d precise control for welding sites has been realized.
