Abstract: [Objective] To solve the problems of low efficiency, high labor intensity, and low safety in traditional manual marking production. [Method] A control system for an automatic marking machine for agricultural machinery parts based on PLC was designed. It mainly consists of a frame, a desktop high-precision stamping machine, a pushing cylinder, a pressing cylinder, a direct vibration feeder, a vibrating disc feeder, an electrical control box, etc. It has automatic loading, marking, unloading, and production counting functions, and can monitor components and production processes through a touch screen. At the same time, prototype assembly, debugging, and trial production were carried out in the factory, and the time consumption and yield rate of manual marking and automatic marking were compared. [Result] The manual marking cycle time is 10.59 seconds per piece, and the yield rate is 98.3%. The automatic marking cycle is 2.02 seconds per piece, and the yield rate is 96.6%. This proves that the system can improve production efficiency and automation level, and ensure a high yield rate. [Conclusion] This study can provide practical technical references and practical models for promoting the intelligent upgrading of production lines and building a high reliability automation system in the agricultural machinery and equipment manufacturing industry, better meeting the objective needs of production automation in the industry.
