<p>A laser robot is equipped with a swing arm (16) mounted to a swivel post (14) implanted to a robot foundation portion (12), a laser emission device (20) provided on the tip of the robot arm (16), and a driving motor (Mv) for driving the swing operation of the robot arm (16) through a precision transmission device (30, 32, 34) placed between the swivel post and the robot arm. The robot comprises a heat removing device which includes a bracket member (26) and an annularly recessed fluid circuit (50) formed in the bracket. The bracket has one end in contact with the end surface of the driving motor on its output shaft side and the other end in contact with the precision transmission mechanism. The heat removing device is located at the joint portion between the precision transmission mechanism (30, 32, 34) and the driving motor (Mv). Cooling water is supplied to the recessed fluid circuit (50) from a cooling water supply source (70) for supplying cooling water to a laser beam conduit of the robot arm (16) so as to cool the bracket member (26). The bracket member (26) thus cooled absorbs and removes the heat of the driving motor (Mv) and prevents heat transfer to the precision transmission mechanism (30, 32, 34). <IMAGE></p> |
