Abstract
With the deepening of Industry 4.0, the application of automation technology in modern manufacturing is becoming increasingly widespread, and the design of automated assembly production lines based on programmable logic controllers (PLCs) has become a key approach to enhancing production efficiency and flexibility. This study aims to design an efficient and reliable automated assembly production line system to meet the current demands of manufacturing for high precision, high speed, and flexible production. To achieve this, a modular design concept was adopted, integrating PLC control technology with sensor networks to develop a comprehensive automated assembly solution. Specifically, by analyzing typical assembly process flows, critical control points were identified, and precise control of each production line segment was realized through ladder diagram programming. Meanwhile, a human-machine interface (HMI) was introduced to optimize operational experience, and the system's stability and maintainability were enhanced through fault diagnosis algorithms. Experimental results indicate that the production line can significantly improve assembly efficiency, reduce the need for manual intervention, and demonstrate strong adaptability, enabling rapid switching between different product types. Additionally, this study innovatively proposes a dynamic scheduling mechanism based on real-time data feedback, effectively addressing bottleneck issues in multi-station collaborative operations and providing valuable reference for the design of similar production lines.
