Abstract:
PROBLEM TO BE SOLVED: To provide a power feed system for an industrial robot with less radiation of electro-magnetic wave and sufficient cooling of an electronic part by shortening the wiring of a power cable. SOLUTION: The robot device includes the industrial robot provided with a plurality of driving means (1) for driving an operation mechanism of a robot; and a control device for controlling and driving a driving means of the industrial robot. An electric driving motor (2) and a deceleration device (3) exist in each driving means (1). Each control device includes a rectifier (6) and a driving device (7) provided for each driving motor (2) and at least one driving device (7) related to the driving means (1) is arranged on the robot adjacent to the driving means.

Abstract:
PROBLEM TO BE SOLVED: To provide a user with various kinds of tools, especially a tool holder capable of applying a spot welding gun to the tool holder. SOLUTION: An industrial robot comprises a plurality of robot arms 4, 5 which are movable in relation to each other and support a tool holder 6a. The tool holder 6a comprises an output shaft journal 8 to which a turning disc 7 is attached. To cause electrical insulation between a tool applied to the tool holder and the robot, an insulating layer is arranged between the turning disc 7 and the shaft journal 8.

Abstract:
The invention relates to a joint comprising a male unit (12) and a female unit (15, 16). The external surface of the male unit (12) is of complementary shape to the internal surface of the female unit (15, 16). The units cooperate and have shapes allowing rotational movement in at least one degree of freedom of the male unit within the female unit. The female unit (15, 16) comprises two socket parts (15, 16). According to the invention biasing means (21 ) is provided for biasing each of the socket parts (15, 16) towards the male unit (12).
Abstract:
The invention relates to a drive unit 1 comprising an electric rotating actuator with a stator 7 and a rotor 6. The drive unit further comprises a speed reducer 5. The speed reducer 5 comprises a wave generator 20 and a flex spline 22. The stator 7, the rotor 6, the wave generator 20 and the flex spline 22 are designed with an centre opening and are all arranged integrated in a common housing 1a such that a tubular passage 31, 59, 82a is provided for through the common housing 1a.
Abstract:
The present invention concerns an industrial robot (1) comprising an upper arm (2) that can be rotated around a first axis (A), a wrist (6) supported by the upper arm that can be rotated around a second axis (B), a hollow turning device (3, 30) supported by the wrist that can be rotated around a third axis (C) that at its front end comprises a turning disk (8, 33) for attachment of a tool, at least one supply line (K) that runs along the upper arm, that the turning device (3, 30) comprises a collar section (10, 36) with a conical envelope surface (12, 45) attached to the turning disk (8, 33), through which at least one opening (14,40) is arranged for the reception of supply lines (K) that pass through the turning device, whereby the opening has an axial extension along a normal (16) perpendicular to the envelope surface (12), where the supply lines are arranged to run through the opening in a direction that has a component parallel to the third axis (C), which opening is arranged to control in a transverse direction and allow in a longitudinal direction displacement of the supply lines. The present invention relates also to a turning device for supply lines in an industrial robot with a robot arm that can be rotated, a method for drawing supply lines, use of the turning device in an industrial robot with a robot arm that can be rotated and use of the industrial robot or the turning device in a welding process.
Abstract:
A robot arm for an industrial robot. The robot arm includes a wrist housing, a wrist, and a turn disc. The wrist is rotatably connected to the wrist housing and the turn disc is rotatably connected to the wrist. A first motor drives the wrist and a second motor drives the turn disc. A first driving rope transmits the motor rotation to the wrist, and a second driving rope transmits the motor rotation to the drive pulley.
