The work aims to improve the stacking operating system of the industrial robot and achieve the convenient operation control and visual monitoring of the working state of the industrial robot with the touch screen of Mitsubishi GS2110-WTBD. Mitsubishi GS2110-WTBD touch screen and PLC used serial communication. PLC and industrial robots used Ethernet communication to achieve information interaction. The external control button and sensor were connected to the QX40 module, the QY10 module was connected to the industrial robot controller I/O interface, and the Mitsubishi Q series PLC controlled the Mitsubishi QD75P1N positioning module to drive the feeding. The programming of PLC and robot made the robot cooperate with the material supply driver, and could realize the precise capture or placement of dynamic objects. Touch-screen design could achieve the selection of different stacking functions and the monitoring of working state. The operating system can make a single industrial robot flexibly applied to the changing control line, and it can be widely used in the control of the stacking industrial robot.
