Publication number: 20250109832Abstract: The invention relates to a headlight with a light source unit and a lens arrangement which is arranged at a predetermined distance from the light source unit for generating a predetermined light image, with a printed circuit board to which the light source unit is electrically contacted, and with a holding device for holding the lens arrangement on a body which is firmly connected to the printed circuit board. A distance adjustment device includes an actuating element which moves in the direction of an optical axis and which engages the light source unit and the printed circuit board, an actuator which can be brought into operative interconnection with the actuating element for adjusting the same, and a control device for controlling the actuator such that the actuating element is moved by in the direction of the optical axis until the currently generated light image corresponds to a predetermined light image.Type: ApplicationFiled: September 30, 2024Publication date: April 3, 2025Inventors: Ingo Engler, Ludger-Josef Grüne, Miguel Lebrato-Rastrojo, Thomas Albert Röbbecke

Patent number: 12202087Abstract: 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.Type: GrantFiled: May 24, 2023Date of Patent: January 21, 2025Assignee: Hella GmbH & Co. KGaAInventors: Daniel Ammann, Ingo Engler, Ludger-Josef Gruene, Frank Jagow, Miguel Lebrato-Rastrojo, Matthias Mattenklotz, Thomas Albert Roebbecke

Publication number: 20240342844Abstract: A device for automated production of screw connections includes an industrial robot with an output member rotatable about an effector axis (W) relative to an end member. A screwing unit is at least indirectly connected to the output member and rotatable by the output member about the effector axis (W). A screwing tool, a protective sleeve, and a preload spring are also included. The screwing tool is: accommodated at least in sections inside the protective sleeve; torque-proof connected with the protective sleeve; and axially displaceable along the effector axis (W) relative to the protective sleeve between a screwing position and a safety position. The screwing tool is biased in the screwing position by the preload spring.Type: ApplicationFiled: April 22, 2024Publication date: October 17, 2024Inventors: Ingo Engler, Frank Jagow, Ludger-Josef Grüne, Miguel Lebrato-Rastrojo, Thomas Albert Röbbecke

Publication number: 20240308152Abstract: A method of setting up a joining device for joining a cover lens to a housing of a vehicle lighting device. The joining device features a mounting fixture and a robot with a suction head, The method features at least the following steps: inserting a housing into the mounting fixture and a cover lens into the suction head; transferring the suction head to an initial joining pose; joining the cover lens to the housing with the suction head in the initial joining pose; measuring the pose of the cover lens relative to a reference-point system, which comprises reference points on the surface of the housing and/or the cover lens; determining a set of translations and/or rotations, which transfer the cover lens to an optimal pose with minimal deviations from a target pose; and correcting the initial joining pose of the suction head with the determined set of translations and/or rotations.Type: ApplicationFiled: April 5, 2024Publication date: September 19, 2024Applicants: HELLA GmbH & Co.

Patent number: 11926382Abstract: 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.Type: GrantFiled: March 19, 2021Date of Patent: March 12, 2024Assignee: Hella GmbH & Co.

Patent number: 11707846Abstract: 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.Type: GrantFiled: March 15, 2021Date of Patent: July 25, 2023Assignee: Hella GmbH & Co.
