摘要：This article introduces the automatic control process of solenoid valve production line with PLC control and touch screen user interface. The production line can produce four types of solenoid valves. There are numerous steps in the production process to ensure the quality of the products, e.gimage error detection and Helium leak detection. The control process uses the Siemens S7-300 as the control core, in conjunction with the Siemens touch screen TP 177B as the human machine interface to achieve the real-time control for the production line. The system control structure, hardware components, software design, as well as the process of automatic control are articulated in this article. The production line runs with consistent stability, the man-machine interface is user friendly, and all the processes have a high level of automation
