This project, based on Industry 4.0 principles, has developed an intelligent adhesive application and assembly system. Its core unit comprises three six-axis collaborative robotic arms, dual flexible vibratory feeders, and high-precision vision modules. The system employs dual robotic arms to precisely pick ring-shaped valve discs and irregular valve bodies from the vibratory feeders, achieving dynamic positioning and posture correction. The third robotic arm, equipped with a custom gripper, performs high-precision assembly of the valve disc onto the body after adhesive application (tolerance ±0.02mm). Featuring a modular design, the system enables multi-machine coordination via an industrial IoT platform, supporting rapid changeovers and compatibility with multiple product specifications. Production efficiency has increased by 300% compared to traditional lines, with a stable yield rate exceeding 99.5%. It finds extensive application in high-end manufacturing sectors such as automotive components and precision instruments.
