Vibration anaysis in robotic ultrasonic welding for battery assembly

Abstract

We present an industrial robotic system that demonstrates the capability to perform the ultrasonic welding of metal tabs on battery cells on the electric vehicles. We investigate the robotic ultrasonic welding by performing robotic welding of the battery module tab of general or/and specific configuration, collecting and analyzing vibration data at various locations of interest on the robot and workpiece, and finally identifying the technical challenges, demonstrate, or propose feasible solutions.
