Method and device for coating the surface of an interior component for motor vehicles
To provide a method for coating the surface of an interior component for motor vehicles which can be carried out in a cost-effective and simple way it is proposed that the interior component is positioned at a distance from a molded part in the region of its surface to be coated, so that a gap is formed between the surface to be coated and the molded part, that the interior component is braced with the molded part, the gap is filled with a liquid surface coating material and said material is cured by exposure to UV radiation. Also proposed are a device for carrying out the method and an interior component which is produced by using the method.
1. A device for coating the surface of an interior component for motor vehicles, comprising:
a molded part adapted for holding the interior component at a distance from a wall of the molded part in a region of a surface to be coated of the interior component, thereby forming a gap between the surface to be coated and the wall; and
a clamping device for bracing of the interior component with the molded part, said clamping device comprising a pivotable clamping lever comprising clamping pins which project in a direction of the molded part, free ends of the clamping pins being placed against a rear side of the interior component which faces away from said gap;
wherein:
during coating, the gap between the surface to be coated and the wall is filed with a liquid surface coating material; and
said material is cured by exposure to ultraviolet radiation.
2. The device as claimed in claim 1 , wherein the clamping device further comprising a frame supporting the molded part.
3. The device as claimed in claim 1 , wherein the molded part is formed such that it is transparent to ultraviolet radiation.
4. The device as claimed in claim 3 , wherein the molded part comprises a supporting element which is transparent to ultraviolet radiation and can be mechanically loaded.
5. The device as claimed in claim 4 , wherein the supporting element is produced from UV-radiation-transparent plastics or glass material.
6. The device as claimed in claim 4 , wherein the supporting element is produced from quartz glass.
7. The device as claimed in claim 1 , wherein the molded part has a UV-radiation-transparent mold which substantially corresponds to a shape of the surface to be coated.
8. The device as claimed in claim 7 , wherein the mold is produced from silicone.
9. The device as claimed in claim 1 , further comprising a sealing element surrounding the interior component in a circumferential direction in the region of the surface to be coated.
10. The device as claimed in claim 9 , wherein the sealing element is connected in one piece to the molded part.
11. The device as claimed in claim 1 , wherein the molded part forms a receptacle for forming the gap, onto which the interior component can be placed.
12. The device as claimed in claim 1 , further comprising at least one spacing element, which can be positioned between the molded part and the region of the surface to be coated of the interior component.
13. The device as claimed in claim 12 , wherein the at least one spacing element is produced from silicone or from polished metal.
