Abstract: PURPOSE: A slip ring device mounted to a rotary shaft of a main motor in a robot arm, and a test machine having the same are provided to be stably operated without the limit of the rotary angle of the robot arm because a signal line is not exposed to the outside. CONSTITUTION: A slip ring device(10) mounted to a rotary shaft of a main motor in a robot arm comprises a frame, firs and second covers(30,60), a rotary ring(40), a insulating ring(50), a pin block(80). The first and second covers and the insulating ring are made of non conductors. The first cover is rotatably installed in the frame, and connected to a rotary shaft of a main motor. The rotary ring is made of conductors. The rotary ring contacts with the first cover, and is stacked along the direction of the rotary shaft. The rotary ring is fixed to the first cover. The insulating ring is stacked on the opposite side to the first cover and fixed to the rotary ring. The second cover is stacked on the opposite side to the rotary ring, and fixed to the insulating ring. The pin block contacts with the rotary ring to be slid, and fixed to the frame.
