Quick Changers, also called tool changers, allow end-of-arm tooling or end effectors to be quickly and accurately mounted to a robot arm. Quick Changers have two separate sides. One side is attached to the robot arm—the other side to the EOAT. The EOAT mounts to the robot by connecting the two sides together. Some models, such as the SENVEX Quick Changer, automatically connect multiple ports including air, vacuum and electric. Others require air, vacuum and electric to be manually connected.
