The LQAT260102 is a dual-station automatic welding machine designed for the high-volume industrial production of gas spring cylinder fittings. It supports the production of various cylinder barrels and threaded fittings in multiple specifications; equipped with a roller-type cylinder barrel feeding system and multiple vibrating bowl fitting loading systems, it enables automatic cylinder barrel loading, multi-stage cleaning and blow-off of both inner and outer surfaces, and performs error-proofing checks on fittings and rejects mixed batches, while seamlessly integrating with welding machines and palletizing transfer carts; Equipped with an EPSON robotic handling system, a Guangzhou Henglong energy-storage welding unit, HBM pressure detection, Keyence displacement monitoring, and IFM cooling water monitoring, the system enables real-time monitoring and storage of all welding process parameters. Its modular recipe management design supports importing process recipes from Excel and rapid changeovers, with the capability to expand to include a CCD inspection station in the future. Multi-level permission-based human-machine interaction and a comprehensive data management system enable production statistics, defect classification statistics, and process data traceability; the Chinese and English operating interfaces make equipment operation more convenient. Comprehensive safety protection and text-based fault alarms guide maintenance, while meeting the equipment capability requirement of CMK ≥ 1.67 to ensure stable, automated batch production.
