CATL’s emphasis on state-of-the-art technology extends even to the fastening tools on its assembly lines. From a fastening standpoint, EV batteries pose several challenges. One is high-mix production. Tools must be able to quickly switch between assembly lines. Tools must accommodate a relatively large torque range and be adaptable to diverse tightening requirements.

Desoutter has worked with CATL from the early stages of its development, helping the company to establish robust tightening standards and improve existing tightening processes. Desoutter supplied CATL with a variety of fastening technologies, including the CONNECT platform, Nexonar positioning system, ERS electric screwdrivers, CVI3 controller, and automatic screw feeders.

Desoutter’s Nexonar 3D spatial positioning system uses infrared sensors to accurately monitor and locate fastening tools or the position of an operator’s hands in critical assembly processes to within 1 millimeter. Nexonar ensures that all screws are tightened in the right place, in the intended sequence, and with the appropriate parameters. The system can be retrofit to existing tools. It is able to detect pitch, roll and yaw of the tool. Several hundred trackers can be monitored simultaneously in real-time and with no latency. It can also be used to ensure as accurate part picking, placement and fulfillment in kitting operations.
