Products Description
This advanced Ultrasonic Torque Welding Machine is specifically designed for positive electrode welding of 4680 and 4695 battery cells. Incorporating multiple patented technologies, the system features an innovative combined equipment configuration and a sophisticated torsional energy exchange mechanism. The machine represents a cutting-edge active welding solution with integrated torsion fabric technology for swellers, offering enhanced performance and precision in battery manufacturing processes.
Principle overview:
The transducer converts electrical energy into mechanical energy of the corresponding frequency and applies it to the interface of the metal sheet to be welded, so that the joint of the metal sheet generates heat instantaneously, and then activates the molecules in the metal lattice, so that the molecules in the joint of the metal sheet penetrate each other and weld together.
Equipment description (including operation flow or process flow)
Process: manual (automatic) feeding – ultrasonic probe welding (cell with fixed tooling) – manual (automatic) blanking. (can be controlled by automatic wire). Beat: 3-5 seconds/piece.
