APPARATUS FOR WRIST JOINT AND ROBOT BY USING THE SAME

摘要

A wrist joint apparatus and a robot using the same are provided to prevent driving units for motion of two-degree of freedom from being exposed outwardly from a joint. A wrist joint apparatus(100) includes a wrist body(110), a multi-axis joint(120), a rotating unit(130), and a driving unit(140). The wrist body is mounted on a robot arm. The multi-axis joint is coupled onto one surface of the wrist body in such a manner that the multi-axis joint is rotatable in a vertical direction with respect to the wrist body. The rotating unit is coupled to one side of the multi-axis joint in such a manner that the rotating unit is rotatable in a horizontal direction with respect to the multi-axis joint. The rotating unit is equipped with a robot hand device. The driving unit is mounted on the wrist body, and rotates the multi-axis joint in a vertical direction with respect to the wrist body and rotates the rotating unit in a horizontal direction with respect to the multi-axis joint.
