Definitions

  • the invention relates to a nozzle device according to one of claims 1 to 18 and a method according to one of claims 19 or 20 for dispensing a preferably viscous, in particular highly viscous, dispensing medium onto a component, preferably for dispensing the dispensing medium onto two side faces and optionally one end face of a fold ( e.g. standing seam), an edge or a transition seam of the component.
  • the component is preferably a motor vehicle component (e.g. a motor vehicle body component), but can also be e.g. B. a component of a commercial vehicle (e.g. a commercial vehicle body component), a component of an aircraft, a window (e.g. a window pane) or a facade component.
  • standing seams (z. B. component edges), as z. B. occur in the sill area or on the side members of a motor vehicle, sealed by means of conventional, robot-guided flat jet nozzles (also called flat stream nozzles) made of hard metal.
  • the standing seam is sealed with PVC (PVC: polyvinyl chloride) from at least one and possibly also from both sides.
  • PVC polyvinyl chloride
  • a robot program is usually created in such a way that the lower edge of the spray jet emitted from the nozzle passes a few millimeters below the standing seam and thus on the standing seam is applied over (“missed").
  • the PVC material that is applied to one side of the standing seam wraps itself around the seam edge to a certain extent and thus seals the lower, corrosion-prone side of the standing seam.
  • the requirements for a conventional PVC seam are usually 15 mm to 25 mm seam width and 1.5 mm to 2.5 mm seam height. So that this can be achieved with a structurally limited nozzle, the slot opening of the conventional flat jet nozzle is convex so that the jet width of the spray jet increases towards the standing seam and thus towards the delivery side.
  • a particular disadvantage of the prior art described above is that part of the released PVC material is "shot past" the standing seam as a result of the process. This has the consequence that the robot guiding the flat jet nozzle and / or the application cell in which the method is carried out is soiled, and thus an increased cleaning effort arises.
  • the application can usually not be set differently due to component tolerances that are usually found in motor vehicle bodies.
  • the component tolerances also mean that the standing seam has to be applied from both sides.
  • Joined sheet metal edges z. B. differ in length from body to body.
  • An object of the invention is to provide a way to deliver a z. B. viscous release medium on at least two side surfaces of a component, preferably z. B. to create a fold, an edge or a transition seam of the component, by means of which the required amount of the delivery medium can be reduced.
