Definitions

  • the invention relates to a coating method and a printing device for use in such a method.
  • the writing EP 3693617 A1 of Boeing Co. discloses a method for microtexturing a substrate surface, comprising: printing the substrate surface with a masking agent to define exposed surface zones on the substrate surface, forming a microtexture on the substrate surface by removing material from the exposed surface zones, and removing the masking agent from the substrate surface.
  • the invention is based on the object of improving painting processes for components, preferably with a view to further automation.
  • step 1.1 the component is or will be provided with a substrate.
  • step 1.1 a further layer is applied to the component material or to the substrate.
  • the masking agent printed in step 1.2 be a liquid film-forming masking agent.
  • the masking agent is preferably a spray film liquid, a printing ink, or a liquid mold release agent.
  • the masking film is formed by evaporating solvent from the masking agent or by activating the masking agent by heating or by irradiation, preferably by irradiation with (UV) light.
  • the masking film is preferably removed by mechanical peeling. It is preferred that in step 1.6 the masking film is weakened, for example by cutting or lasering. It is preferred that in step 1.6 the masking film is Compressed air is removed, preferably blown away. It is preferred that in step 1.6 the masking film is removed by means of a suction device, preferably by suction. It is preferred that the mechanical removal is carried out by a gripping device. It is preferred that the masking film has a starting point for removal, wherein the starting point is formed by a strip element embedded in the masking film, for example an adhesive strip, wherein in Step 1.6 the starting point is mechanically detected to begin removal.
  • step 1.6 the masking film is removed by means of brushing, rubbing, erasing, water jet and/or high pressure cleaner.
  • One idea of the invention is to apply the masking agent or masking film to the component using an inkjet process. This can be a fully automated process, eliminating the need for manual masking of the component before painting. Inkjet processes for printing three-dimensional objects are known as such (e.g., Heidelberger Druckmaschinen Omnifire).
  • the process proposed here represents a new application for inkjet printing, using the applied material as a masking film for subsequent coating.
  • the masking film printed in this way can be easily removed after coating.
  • the printing ink can, for example, be a UV ink that cures into a finished masking film upon exposure to UV light.
  • a spray film liquid as a masking agent, provided it has approximately the same viscosity as functional printing inks.
  • a liquid mold release agent such as that used in the production of fiber composite components in a mold, could be printed as a masking agent.
  • the mold release agent preferably has a similar viscosity to the functional printing ink.
  • top coat (clear coat or the like) can assist the removal of the masking agent.
  • the ideas described here enable a printable masking film that can eliminate manual work on the component.
  • Printing preferably enables precise and targeted dosing on the component, reducing waste and improving the quality of the result.
  • printing enables full automation of the masking process, ultimately allowing the entire painting process to be automated. Overall, this also reduces the overall painting process time.
  • Fig. 1 shows schematically a painting process with the steps S10 to S18.
  • an aircraft component 10 is provided.
  • the aircraft component 10 can, for example, be a component arranged on the outside of an aircraft.
  • the aircraft component 10 can be painted for the first time or treated for repainting.
  • the aircraft component 10 can undergo pretreatment (e.g., cleaning, sanding, and the like).
  • a first paint system can be applied to the aircraft component as a substrate 12.
  • the paint system can contain various layers, for example, adhesion promoters, primers, or other functional layers (e.g., corrosion and/or erosion protection).
  • a further layer 14 can also be applied to the substrate 12.
  • Application can be carried out in the usual way by rolling, brushing, or spraying.
  • a liquid film-forming masking agent 16 is printed.
  • the printing is performed using an inkjet print head.
  • the masking agent 16 can be a spray film liquid, a functional printing ink, or a mold release agent.
  • the masking agent 16 forms a closed masking film 18 by evaporating the solvent from the masking agent 16. It is also possible that the masking agent 16 only forms the masking film 18 upon activation, for example, by UV light or heat. The masking film 18 lies against the surface or adheres only minimally to the surface, but does not form a bond. This results in good removability of the masking film 18 from the underlying layer.
  • topcoats can be applied as coating agents 20 in a manner known per se. These can preferably be color-imparting, for example, to create a desired logo.
  • a topcoat layer 22 (usually a clear coat) is additionally applied to the coating agent 20. The coating agent 20 and/or the topcoat layer 22 can assist in the removal of the masking film 18 in the further process.
  • the masking film 18 is mechanically removed, for example peeled off, thereby exposing the masked surface area 24.
  • Fig. 2 and Fig. 3 schematically shows a printing device 26 that can be used for the method described above.
  • the printing device 26 comprises a robot arm 28, to the end of which a print head 30 is attached.
  • the print head 30 is designed as an inkjet print head 32 and, depending on the type of ink, can have an activation unit 34 for activating or curing the printed functional printing ink.
  • the printing device 26 further has a reservoir 36 containing the functional printing ink or the masking agent 16.
  • the print head 30 follows a predetermined masking path 38 on the aircraft component 10 to mask the surface area 24, for example, in an elliptical shape. Due to the targeted application, the surface area 24 is sharply masked, resulting in a clear contour after removal.
  • the pressure device 26 can comprise a masking film removal device.
  • the masking film removal device can grasp the masking film 18 and mechanically remove it from the aircraft component 10.
  • the masking film removal device can be a laser, a knife, a compressed air nozzle, a gripper, a suction cup, a suction tube, a Device for a water jet or high-pressure water jet, a brush and/or a rubbing or erasing device.
  • Fig. 4 is a photograph of a peel test performed by the applicant.
  • the masking film 18 was applied to a white base coat layer 42 and subsequently covered with a clear coat.
  • the masking film 18 was then successfully peeled off the base coat layer 42 manually between two predetermined separation lines 44.
