Abstract
Method for producing a screw connection using a robot (10) in which at least two screw elements are screwed together via respective threads, by rotating a first screw element, held at least indirectly on a terminal axis (24) of the robot (10), relative to the second screw element while bringing the threads into engagement, wherein a screwing torque acting on the terminal axis (24) is detected by means of a sensor assigned to the terminal axis (24), where The screw-in torque acting on the terminal axis (24) is monitored by means of a second sensor assigned to one of the terminal axis (24) of the robot (10) and provided in addition to the first sensor. characterized by the fact that as the first sensor is a first torque sensor integrated into the robot (10) and / or as the second sensor is a second torque sensor integrated into the robot (10). and in which a first signal provided by the first sensor and characterizing the screw-in torque detected by the first sensor is transmitted via a first signal line and a second signal provided by the second sensor and characterizing the screw-in torque detected by the second sensor is transmitted via a second signal line provided in addition to the first signal line to an evaluation unit.
