  • Patent number: 11364588
    Abstract: A method for cleaning using solid carbon dioxide is provided. Adhesive surfaces of the vehicle components are cleaned automatically in an assembly line including several work stations. The adhesive surfaces of the vehicle components may be adhesive surfaces of coated or painted vehicle components. The vehicle components may be composed of a metal alloy such as a steel or aluminum alloy, and/or composed of a fiber composite material such as carbon-fiber-reinforced plastic. The adhesive surfaces of the vehicle components may be cleaned with specifically adapted cleaning parameters.
    Type: Grant

    Assignee: Bayerische Motoren Werke Aktiengesellschaft
    Inventors: Bernd Held, Lukas Langgaertner
  • Patent number: 11161219
    Abstract: A device for cleaning adhesive surfaces of vehicle components using solid carbon dioxide is provided. The device may be used for automated cleaning in an assembly line with a plurality of work stations. The device includes a chamber-type cleaning area for vehicle components, a blasting device with a jet nozzle for emitting solid carbon dioxide onto the vehicle components, a transport device for transporting the vehicle components through the cleaning chamber, and a charge discharge device for discharging an electrostatic charge from the vehicle components in order to structurally and/or functionally improve the device.
