Abstract: A multi-tasking end effector system includes a base frame connected to a robot arm of a robot. A first shaft is rotatably supported on the base frame. A first pin-wheel assembly is rotatably mounted to the shaft at a first end of the base frame. Multiple first die assemblies are mounted to the first pin-wheel assembly. A second pin-wheel assembly is rotatably mounted to the shaft at a second end of the base frame. Multiple second die assemblies are mounted to the second pin-wheel assembly and individually oriented in mirror image configuration to one of the multiple first die assemblies. An index motor rotates the first shaft and co-rotates paired and mirror image die assemblies. First and second tab-bending actuators mounted to the base frame are operated to bend opposed cell tabs of a battery cell positioned between the first and second pin-wheel assemblies.
