Title:
INDUSTRIAL ROBOT
Document Type and Number:
WIPO Patent Application WO/2014/024690
Kind Code:
A1
Abstract:
The present invention provides an industrial robot that is disposed and used in a vacuum state, wherein driving motors that are disposed in the atmosphere of the inside of an arm and are for driving a hand and the arm can be efficiently cooled. An industrial robot (1) is provided with the following: a motor (46) for pivoting a second arm unit (24) with respect to a first arm unit (23); a motor (47) for pivoting a hand (13) with respect to the second arm unit (24); a deceleration mechanism (48) for decelerating the rotation of the motor (46) and performing transmission to the second arm unit (24); and a deceleration mechanism (49) for decelerating the rotation of the motor (47) and performing transmission to the hand (13). The hand (13) and an arm (14) are disposed in a vacuum state. The deceleration mechanisms (48, 49) are disposed on the same axis so that the pivotal center of the second arm unit (24) with respect to the first arm unit (23) and the axial center of the deceleration mechanisms (48, 49) coincide. An internal space (45) of the first arm unit (23) that is formed hollow is at atmospheric pressure. Provided in the internal space (45) are the motors (46, 47) and the deceleration mechanisms (48, 49).
