Vibration analysis in robotic ultrasonic welding for battery assembly

Abstract

This paper presents the vibration analysis of a robotic system, which performs ultrasonic welding of metal tabs on rechargeable batteries commonly used for hybrid or electric vehicles. A robotic battery-welding cell was set up, battery tab welding was performed and the vibration data was collected by using accelerometers and LVDT sensors. The data was analyzed and we learned if/how the vibration affected the robot arm and the battery object under various welding configurations.
