Guoyu Intelligent provides core execution support for the ultrasonic welding and punching composite station of automotive bumpers. For large and complex bumper assemblies, high-rigidity planar positioning locking fixtures and large-span pallets are configured to ensure absolute stability of multi-curved parts during transfer. Paired with overhead suspended follow-up modules, it achieves precise coordination between ultrasonic welding heads and punching units, effectively avoiding acoustic transmission loss on irregular curved surfaces and secondary punching deviations, ensuring dense and void-free weld seams. The entire solution significantly improves the continuous cycle time and finished product yield of interior and exterior part welding and punching lines.
