  • Patent number: 11926382
    Abstract: An assembly system is provided for automotive lamps and an operation method thereof. The assembly system includes two kinds of functional robots and many functional stations, and it uses the functional robots to transfer workpieces between the various functional stations to realize automatic gluing, fastening and whole lamp performance testing, etc., thereby reducing the amount of manual intervention and improving process integration. Further, the assembly system may provide an assembly system with a two-sided assembly line operating simultaneously, which greatly improves the working efficiency of thereof.

  • Publication number: 20230294224
    Abstract: A device is provided for the automated production of screw connections, and includes an articulated robot with an output element and an end link. The output element is arranged on the end link so as to be rotatable around an effector axis (wE). A screwdriver tool is provided, and can be rotated around the effector axis (wE) by the output element. At least one gear may also be provided, where the gear has a direct operative connection to the output element and the screwdriver tool and is set up for transmission of a rotary speed between the output element and the screwdriver tool.

  • Publication number: 20230271332
    Abstract: An apparatus for the automated production of screw connections, having an articulated-arm robot and an effector, which is accommodated on an output element of an end member of the articulated-arm robot so as to be rotatable about an effector axis. The effector is in the form of a screwdriving tool, wherein the apparatus has a mouthpiece for providing a screw, the mouthpiece being accommodated on the end member by means of a linear guide and being movable along the effector axis between a feeding position and at least one screwing position.

  • Patent number: 11707846
    Abstract: A first robot for handling at least one first workpiece in a first processing operation of the apparatus, a second robot cooperating with the first robot for processing the at least one first workpiece in the first processing operation, and at least one first workpiece holder for holding the at least one first workpiece during the first processing operation. In order to improve robot-assisted processing of workpieces which differ from one another, the first robot handles at least one second workpiece and the second robot processes the at least one second workpiece in a second processing operation of the apparatus. The first robot or the second robot in order, in a changeover operation of the apparatus, to replace the at least one first workpiece holder automatically by at least one second workpiece holder for holding the at least one second workpiece during the second processing operation.
