Document Type and Number:
Japanese Patent JP7340129
Kind Code:
B2
Abstract:
In a robot (1) for gripping and/or holding objects (2), in particular workpieces, tools or carrier parts, the robot comprising:at least one robot arm (3, 4, 5) which is supported on a support frame (19) and is movable in space in at least one translational and/or rotational degree of freedom,a gripping and/or holding device (6), on which the respective object (2) is supported in a positionally oriented manner and/or held in a rotational arrangement,at least one electric motor (9) provided in the gripping and/or holding device (6), by means of which a torque and/or a clamping force is generated which acts on the object (2), anda drive shaft (24) mounted in the robot arm (5), which is coupled in a driving manner to the gripping and/or holding device (6), preferably in such a way that the gripping and/or holding device (6) rotates about its own longitudinal axis (6′),the gripping and/or holding device (6) arranged at the free end of the robot arm (5) should be freely movable in space, so that rotation about its own longitudinal axis (6′) can be carried out as often and as quickly as desired.This is achieved in that an interface (31) is provided between a free end (10) of the robot arm (5) at the end and the gripping and/or holding device (6), which interface (31) is bridged by a coupler (25) fixed in a non-rotating arrangement to the robot arm (5) and by a flange (11) adapted thereto, which flange (11) is connected in a non-rotating arrangement to the gripping and/or holding device (6) and the drive shaft (24), in that a first inductively operated transceiver (12) is provided in the coupler (25), which transceiver (12) is connected to a power source (15) via an electrical line (14) fed to the robot arm (5), in that a second inductively operated transceiver (13) is provided in the flange (11), which is connected to the electric motor (9) in the gripping and/or holding device (6) via electrical lines (14), and in that an air gap (21) is provided between the coupler (25) and the flange (11) as a component of the interface (31).
