    • The invention relates to a robot holder for fixing a fluid-cooled joining tool (6) rotatably about a longitudinal axis (L) on a robot arm (2) of a joining robot with a stator (3) that can be fixed on the robot arm (2) and a rotor (4), which comprises a connection for the joining tool (6) and can be rotated about the stator (3), wherein a feed-through (13) for a joining medium, particularly a welding or soldering wire, runs inside the robot holder through the stator and the rotor. For the even more flexible use of such automated joining tools operating with a joining medium on robots, it is desirable to enable for a rotation of the joining tool that is less limited in the angular range, preferably by a range of at least 360° and even more up to rotatability that is delimited by robot parameters but otherwise free, and to create an accordingly adapted passage for cooling fluid. According to the invention, the robot holder comprises in the stator (3) and in the rotor (4) at least one fluid line designed as bore (8a, 8b, 9a, 9b) for a cooling fluid feed and the cooling fluid return, wherein between the stator (3) and the rotor (4) at least one sealed annular chamber (10, 11) is formed for the cooling fluid feed and the cooling fluid return, the respectively associated fluid lines of the stator (3) and the rotor (4) for a fluid passage ending in said annular chamber. The invention further relates to a joining robot comprising a novel robot holder.
