摘要：本文主要介绍了由视觉传感器、传送带及机械手构成的分拣系统和可编程序控制器与位置控制单元构成的控制系统,实现对工件表面的检测及对次品工件的剔除操作。视觉传感器实施工件检测,配置位置控制单元的参数实现机械手各轴的精确定位,运用脉冲指令控制传送带的运动节拍,调用移位寄存器指令实现检测与剔除信号的衔接,编写梯形图控制程序,实现了机械手对次品的抓取及剔除操作。经过实践证明,该控制系统结构简单,编程简便,性价比高,具有应用价值。
The measure system composed of visual sensor, conveyer and robot hand is mainly introduced in this paper, PLC with its PCU is used to control flow for surface measure and inferior product removing. The visual sensor is used to measure product, pa- rameter of PCU is set to realize position precision control for five-freedom robot hand. And the pulse instruction is applied to control work time of conveyer. Furthermore,the ladder chart with SFT is programmed to transmit measure signal and remove inferior product operation. It has been proved practically that the control system has a simple structure, reliable operation, easy aceess for modification and valuable application.
