PURPOSE:To improve the safety of the laser robot by providing conduits for a laser optical path disposed to a 1st robot arm to the center of relative rotation of the 1st and 2nd robot arms and forming and disposing a wiring cable in a spiral state to the outer periphery thereof. CONSTITUTION:The 1st robot arm 26 is mounted to the peak part of a column 24 and the 2nd robot arm 28 which can swivel horizontally is disposed to the front end 26a thereof. The laser light passes the inside of a hollow stationary shaft 54 erected from the arm 26 into the arm 28 and arrives at a laser output part 34 by passing the conduits 50, 52, 90 and reflecting mirrors 84, 86, 88, 94. Further, the cable 41 enters an inlet 58a and is spirally wound around the outer peripheral surface of the hollow shaft 54, by which the cable is wired to a motor MZ in the 2nd arm 28. The laser optical path is built into the robot machine body and further the required wiring is executed without generating tension and excess force on the cable 41 and, therefore, the safety of the laser robot is improved. |
