This technology is a gripper device mounted on the end of a robot arm, capable of selectively performing gripping tasks and switch-pressing operations. It features a rotatable pressing bar inside the gripper jaw and utilizes surface contact between a polygonal end and an elastic member (leaf spring) to stably lock the rotation position or switch the rotation state semi-automatically.
In remote working environments, the need to repeatedly swap robot grippers to perform different tasks—such as operating instrument panel switches, controlling valves, or grasping objects—has historically led to reduced operational efficiency and increased costs.
This technology incorporates a gripper button unit (pressing bar) rotatably mounted on the gripper jaw, designed to rotate and lock in 90-degree increments using a polygonal chamfered section at one end of the bar and an elastic member. By limiting the rotation angle via a stopper and a rotation-blocking unit, the structure allows the pressing bar to be retracted during gripping and extended for switch operation. Applicable to logistics picking, service robots, and manufacturing automation, this robot gripper enables the performance of diverse tasks without tool changes, thereby improving the efficiency of remote maintenance operations and ultimately increasing human resource efficiency.
This invention was developed with support from the Ministry of Knowledge Economy for the development of remote operation service engines and force-feedback remote-controlled robot system technologies for remote tasks.
