Abstract
A permanent magnet brake system consists of a first body with an active area and a second body with an active area. Between the first and the second active area is a fluid. The fluid activates with a magnetic field when the brake is activated.
Claims19
An industrial robot (1) including a manipulator (2) and a control system (3), which manipulator comprises a first robot part (4) and a second robot part (5) arranged displaceable relative to each other and a drive means (6) that brings about the movement between the robot parts characterised in that the driving means (6) comprises a brake system (7) regulatably arranged in collaboration with the control system (3), which braking system comprises a first body (11) with a first surface (24) and a second body (12) with a second surface (25) and that a medium (22) is arranged between the first surface (24) and the second surface (25), which medium transfers a force (F) between the bodies when in an active condition and that the braking system (7) comprises a magnetic arrangement (10) comprising at least one permanent magnet (18).
Industrial robot according to any one of the preceding claims, characterised in that the medium (22) comprises a fluid.
Industrial robot according to any one of the preceding claims, characterised in that the medium (22) is a MR-fluid.
Industrial robot according to any one of the preceding claims, characterised in that the first surface (24) and the second surface (25) are arranged to be parallel to each other.
A method for manufacturing an industrial robot (1) including a manipulator (2) and a control system (3), which manipulator comprises a first robot part (4) and a second robot part (5) arranged displaceable relative to each other and a drive means (6) that brings about the movement between the robot parts (4), (5) characterised in that the driving means (6) is caused to comprise a brake system (7) regulatably arranged in collaboration with the control system (3), that the brake system (7) is caused to comprise a first body (11) with a first surface (24) and a second body (12) with a second surface (25), and that a medium (22) is placed between the surfaces (24), (25), which medium is caused to be activated to transfer a force (F) between the bodies and that the braking system (7) is caused to comprise a magnetic device (10) comprising at least one permanent magnet (18).
A method for an industrial robot (1) including a manipulator (2) and a control system (3), which manipulator (2) comprises a first robot part (4) and a second robot part (5) arranged displaceable relative to each other and a drive means (6) that brings about the movement between the robot parts (4), (5), characterised in that the driving means (6) comprises a brake system (7) regulatably arranged in collaboration with the control system (3), that the brake system (7) comprises a first body (11) and a second body (12) and a medium (22) that combines the bodies (11), (12), that the medium (22) is activated by an magnetic field (A, B) generated by at least one permanent magnet (18) comprised in the brake system (7) whereby a force is transferred between the bodies such that the movements of the robot (1) are regulatably braked and brought to stop.
The use of a medium (22) that in an active condition transfers a force (F) in a brake system (7), the brake system (7) comprising at least one permanent magnet (18), in an industrial robot (1) in order to brake dynamically the movements of the robot and in order to hold a load stationary.
