Abstract: The winding machine is a special equipment which can exclusively wound muliti-turn potentiometer winding continuously. Using the PLC as the main control machine, the touch screen as user interface, step motor, servo motor drive of the winding machine system was introduced in the article. The principle, classification of touch screen and the control style of touch screen human-machine interface was also described in detail. The human-machine interface design of touch screen was completed. The control system, working principle of servo motor and the selection of servo motor and its driving machine was also introduced in the article. Finally made the servo motor control system based on touch screen and PLC come true. The research purpose of the subject is to design a low-cost, high-speed, reliable servo system of winding machine to replace the original system, the article provide the control program, the selection of main components and cost accounting of the entire system. This article completed the application design of the touch screen and the control program design of PLC servo motor, basically realized the target of the design as required.
