Abstract

In a method for treating the surface of objects, in particular vehicle bodies, the object is provided with a functional pattern by means of a coating process.

First claim

The invention claimed is:

1. A method for surface-treating vehicle bodies or parts thereof comprising:
providing a vehicle body or parts thereof with a functional pattern by means of a coating procedure,
wherein the functional pattern is provided in the course of a painting process in which the vehicle body or parts thereof is coated in one or more steps in a coating chamber and the vehicle body or a parts thereof is provided with the functional pattern by means of a pattern application device that is movably guided by a robot; and
further wherein the functional pattern is imprinted on a printing surface of the vehicle body or parts thereof, which is a surface region of the vehicle body or parts thereof which, during the coating process for the coating or after its completion, is located externally and is available for printing.

2. The method according to claim 1 , wherein the functional pattern is integrated in the coating of the vehicle body or parts thereof or is applied externally on the coating of the vehicle body or parts thereof.

3. The method according to claim 1 , wherein the printing surface is formed on the surface of a material wall of the vehicle body or parts thereof or a layer of a coating material.

4. The method according to claim 1 , wherein the functional pattern is a custom pattern, an information pattern or a technical pattern.

5. The method according to claim 1 , wherein the functional pattern is formed as a relief pattern.

6. The method according to claim 1 , wherein the application device controlled by the robot is a multi-axis print robot having a print head.

7. The method according to claim 1 , wherein the robot further guides a paint application device in addition to the pattern application device, the robot carrying an exchangeable head having the paint application device and the pattern application device.

8. A method for surface-treating vehicle bodies or parts thereof comprising:
providing a vehicle body or parts thereof with a functional pattern by means of a coating procedure,
wherein the functional pattern is provided in the course of a painting process in which the vehicle body or parts thereof is coated in one or more steps in a coating chamber and the vehicle body or a parts thereof is provided with the functional pattern by means of a pattern application device that is movably guided by a robot; and
further wherein the functional pattern is formed as a relief pattern.

9. The method according to claim 8 , wherein the functional pattern is integrated in the coating of the vehicle body or parts thereof or is applied externally on the coating of the vehicle body or parts thereof.

10. The method according to claim 8 , wherein the functional pattern is imprinted on a printing surface of the vehicle body or parts thereof, which is a surface region of the vehicle body or parts thereof which, during the coating process for the coating or after its completion, is located externally and is available for printing, wherein the printing surface is formed on the surface of a material wall of the vehicle body or parts thereof or a layer of a coating material.

11. The method according to claim 8 , wherein the functional pattern is a custom pattern, an information pattern or a technical pattern.

12. The method according to claim 8 , wherein the application device controlled by the robot is a multi-axis print robot having a print head.

13. The method according to claim 8 , wherein the robot further guides a paint application device in addition to the pattern application device, the robot carrying an exchangeable head having the paint application device and the pattern application device.

14. A method for surface-treating vehicle bodies or parts thereof comprising:
providing a vehicle body or parts thereof with a functional pattern by means of a coating procedure,
wherein the functional pattern is provided in the course of a painting process in which the vehicle body or parts thereof is coated in one or more steps in a coating chamber and the vehicle body or a parts thereof is provided with the functional pattern by means of a pattern application device that is movably guided by a robot; and
further wherein the application device controlled by the robot is a multi-axis print robot having a print head.

15. The method according to claim 14 , wherein the functional pattern is integrated in the coating of the vehicle body or parts thereof or is applied externally on the coating of the vehicle body or parts thereof.

16. The method according to claim 14 , wherein the functional pattern is imprinted on a printing surface of the vehicle body or parts thereof, which is a surface region of the vehicle body or parts thereof which, during the coating process for the coating or after its completion, is located externally and is available for printing, wherein the printing surface is formed on the surface of a material wall of the vehicle body or parts thereof or a layer of a coating material.

17. The method according to claim 14 , wherein the functional pattern is a custom pattern, an information pattern or a technical pattern.

18. The method according to claim 14 , wherein the robot further guides a paint application device in addition to the pattern application device, the robot carrying an exchangeable head having the paint application device and the pattern application device.

19. A method for surface-treating vehicle bodies or parts thereof comprising:
providing a vehicle body or parts thereof with a functional pattern by means of a coating procedure,
wherein the functional pattern is provided in the course of a painting process in which the vehicle body or parts thereof is coated in one or more steps in a coating chamber and the vehicle body or a parts thereof is provided with the functional pattern by means of a pattern application device that is movably guided by a robot; and
further wherein the robot further guides a paint application device in addition to the pattern application device, the robot carrying an exchangeable head having the paint application device and the pattern application device.

20. The method according to claim 19 , wherein the functional pattern is integrated in the coating of the vehicle body or parts thereof or is applied externally on the coating of the vehicle body or parts thereof.

21. The method according to claim 19 , wherein the functional pattern is imprinted on a printing surface of the vehicle body or parts thereof, which is a surface region of the vehicle body or parts thereof which, during the coating process for the coating or after its completion, is located externally and is available for printing, wherein the printing surface is formed on the surface of a material wall of the vehicle body or parts thereof or a layer of a coating material.

22. The method according to claim 19 , wherein the functional pattern is a custom pattern, an information pattern or a technical pattern.
