Definitions

  • the invention relates to a method and an apparatus for Repair of small paint defects in paint layers according to the generic term of claim 1 or with respect to the device according to Preamble of claim 11 as it relates to the method from the generic DE 196 46 956.2 emerges as known.
  • the object of the invention is the underlying repair method to improve in that the repair a has higher quality.
  • the task is inventively in a method with the Method steps of claim 1 or with respect to the device solved with the features of claim 11.
  • Figure 1 is a section of a curved powder coating 1 of a substrate.
  • the substrate can, for example, be made of metal, Plastic and / or fiber-reinforced plastic manufactured be.
  • the powder coating layer 1 can despite different precautionary errors such as included Grains of dust occur.
  • To repair a buggy This will be done within a very limited framework, in particular set and hardened powder coating layer 1 with a recess 2 provided in the present embodiment is cylindrical.
  • the maximum Depth of the powder coating layer 1 is made in the recess 2 In the present case, the fault, for example the grain of dust eliminated.
  • the recess 2 is cutting and in this case in particular using asymmetrical milling - i.e. the cutting of the Milling cutters do not run through the center of the milling Surface or grinding introduced into the powder coating layer 1.
  • the recess 2 can also be drilled and / or sawn and / or burned out and / or punched out by laser and / or be ground. With all types of insertion the recess 2 in the powder coating layer 1, care must be taken that the recess 2 in terms of its area or width and also in terms of their depth with precisely defined dimensions as well as with a predetermined edge contour in the powder coating layer 1 is introduced.
  • the one which is at least partially crosslinked before being introduced into the recess 2 Packing body 3 corresponds to the volume of the recess 2 dimensioned and coherent in the sense of a monolith; i.e. the diameter of the monolithically related Packing body 3 corresponds approximately to the width of the recess 2 and the layer thickness of the packing 3 is approximately the depth of the Recess.
  • this exact dimensioning in can be realized in a simple manner in that the filler body 3 molded from a previously made paint film, in particular is punched out. With at least some effect powder coatings this lacquer film is used to maintain the desired optical properties expediently by electrostatic spraying produced.
  • a pressure body 4 is created, which is expedient protrudes beyond the edges of the recess 2 and further conveniently flat to the edges of the recess 2 on the Visible side 5 of the powder coating layer 1 is applied.
  • the filler 3 is the outside of the recess 2 arranged powder coating layer 1 connected.
  • connection is preferably made by an adhesive layer (not shown), either on the packing 3 or already before the filling body 3 is introduced into the recess 2 the corresponding walls of the packing 3 arranged becomes.
  • the filler introduced into the recess 2 3 and possibly also the adhesive layer heated and / or for Brought reaction.
  • heating and / or by reaction hardens in particular the packing 3 and possibly also the Adhesive layer.
  • a pressure on the filler body 3 exercised. Since the surface of the Pressure body 4 - ie the contact surface 6 - expediently is as smooth as possible, results from this pressure also a good surface of the hardened packing 3.
  • the reaction is preferably carried out by UV radiation and / or electromagnetic, especially IR radiation, and / or hotter Air introduced and / or maintained.
  • electromagnetic radiation especially IR radiation, and / or hotter Air introduced and / or maintained.
  • the pressure body 4 expediently in the area has its contact surface 6 on the packing 3 pores, through which the resulting gas is discharged.
  • the contact surface 6, in a special version also the entire pressure body 4 made of so-called nanoparticles be made.
  • the connection of the filling element 3 and / or the curing of the packing 3 by means of electromagnetic, initiated IR radiation in particular, it is expedient the size of the nanoparticles is smaller than the wavelength to choose the radiation in question.
  • filler 3 depending on the material used during curing can have a volume shrinkage, it is also favorable to Filling body 3 to be provided with a volume that is approximately the volume the recess 2 plus that which occurs during hardening Volume shrinkage of the packing 3 corresponds.
  • a powder coating layer 1 is shown in the area a faulty place of the particularly tied and hardened powder coating layer 1 with a truncated cone Recess 2 is provided.
  • the cone of the recess 2 joins the substrate.
  • the cutout 2 introduced into the powder coating layer 1 becomes simultaneous the error, for example a grain of dust, is eliminated.
  • the frustoconical recess 2 is included arranged packing 3 and arranged above the packing 3 Repair device shown.
  • the packing 3 is made of powder coating and / or a precursor of the powder coating manufactured and shaped in particular plate-like.
  • the edges of the packing 3 are in terms of their geometric dimensions and also with regard to their course, for example when they are introduced the recess 2 is not necessarily round, but may also be kidney-shaped, for example, the edges of the recess 2 adjusted.
  • the filler 3 is ejected from the covering lacquer film and inserted directly into the recess 2 when ejecting and / or is pressed in.
  • the packing 3 arranged in the recess 2 is connected to the powder coating layer 1 arranged outside the recess 2 connected by the measures listed above.
  • the connection takes place through a direct connection of the material of the packing 3 with the surrounding material of the powder coating layer 1.
  • the connection of the filler 3 with the powder coating layer 1 does not have to run along the entire common area but can be limited to individual common subareas be. In the case of fillers formed from fragments 8 3 at the same time the fragments 8 in the same Way connected.
  • the repair device is used for connecting and / or curing 9 on the powder coating layer 1 and on the visible side 5 of the packing 3 created.
  • the repair device 9 is designed in the manner of a pressure bell and has on it an end region on the pressure body 4, which is axially movable is. With such a design of the repair device 9 the pressing during connection or the curing of the packing 3 in a simple manner be made by the pressure inside the repair device 9 increases and thus the pressure body 4 in the direction the powder coating layer 1 and thus the packing 3 expressed becomes.
  • the contact surface 6 of the pressure body 4 is also advantageous if the pressure body 4 at least in the area of the contact surface 6 at least to a small extent elastic and / or flexible is because it is then easier on curved surfaces Can adapt or nestle to them.
  • a radiation source 10 can be arranged with which the connection and / or the curing of the packing 3 can be carried out can.
