Abstract
Abstract With this device for an automatic mounting of connector shells (5) and electric conductors, in each case, a connector shell (5) is mounted, with the aid of an industrial robot (1), onto both contact parts (8.1, 8.2) of an electrical conductor at the end of a cable-processing line. Each end of the electric conductors is gripped by the first double gripper (11) of an additional transfer module (40) and, in a mounting position (32), is transferred to a stationary gripper (20). Before this transfer, if the electric conductor is gripped by the first double gripper (11) alone, then the conductor shells are mounted onto the contact parts and the mounting force is tested. After the stationary gripper (20) takes over the electric conductor, the first double gripper carries out a reverse cycle motion into a transfer position (30) in order to grip a new electric conductor. At the same time, after the mounting pressure has been checked, the robot gripper of the industrial robot (1) mounts the connector shell (5) completely onto the contact part (8.1, 8.2) and the perfect mounting is determined by a checking of the withdrawal pressure. The electric conductor (8), equipped with the connector shell (5), is placed by a separating motion of the robot gripper (3) of the industrial robot (1) under the fixed separator element (18).
