A fully automated assembly system for the hardware industry, uses high-precision servo drive and pneumatic actuation technology to achieve high-speed assembly of complex hardware parts. It integrates multi-station processes such as laser welding, riveting, and automatic lock screw tightening, combined with visual positioning technology to ensure high-precision assembly. The modular design supports multi-specification product production across multiple stations. Through robotic automatic loading/unloading and integration with intelligent logistics systems, it realizes full-process unmanned operation. A special dust-proof protection structure adapts to metalworking environments, and equipped with in-line inspection modules, significantly improving production efficiency and quality stability. The system has quick changeover capability, suitable for large-scale hardware manufacturing scenarios.
