AI Technical Summary

Technical Problem

Existing composite material molding production lines suffer from insufficient equipment scheduling flexibility, are unable to adapt to dynamic and irregular cycle characteristics, have low equipment utilization, high production scheduling delays, and poor coordination among various processes, resulting in low production efficiency and material waste.

Method used

A PLC-based collaborative control system is adopted, which realizes full-process motion learning and automated mold switching through the collaborative control of the master station arbitration PLC and the production line slave station PLC, dynamically schedules equipment utilization, and adopts a global IO address mapping and permission isolation mechanism to ensure the efficiency of equipment collaborative response and mold switching.

Benefits of technology

This has resulted in improved equipment utilization, significantly increased mold switching efficiency, enhanced production process stability, reduced equipment response delay, and a substantial increase in production efficiency, achieving closed-loop control throughout the entire process and consistent product quality.

Abstract

This invention discloses a PLC-based collaborative control system for composite material molding production lines, belonging to the field of automated composite material molding technology. It includes a production line execution unit and a PLC collaborative control unit. The production line execution unit includes a front-end production line, which interfaces with shared equipment via a transfer module. The master station arbitration PLC, production line slave PLCs, and shared equipment are connected via a communication unit. The PLC collaborative control unit incorporates an automatic mold switching control module and a native PLC-based full-process motion learning unit. The master station arbitration PLC also performs global scheduling, global clock synchronization, global IO address mapping planning, mold switching, and motion learning. The production line slave PLCs communicate with each production line individually. This PLC-based collaborative control system for composite material molding production lines can achieve motion learning, automated mold switching, and dynamic collaborative control throughout the entire process from raw materials to finished products, adaptively matching the dynamic characteristics of the production line.
