Method for operation of six-axle-robot for coating/printing two or three dimensional curved work-pieces, involves utilizing trajectory deviation between travel paths as correction signal for controlling print head matrices

摘要

The method involves fixing a work-piece (10) or a print head arrangement (13) at a rotating head (6) of a coating-and printing device, which is designed as a multi-axle-robot (1). The work-pieces move along a real trajectory (11) and a target trajectory (12) relative to the print head arrangement in a controlled manner. Trajectory deviation between the real trajectory and the target trajectory is utilized in real time as a correction signal for controlling print head matrices (14-17) of the print head arrangement. Corrected pixel-matrices are printed on the work-pieces. An independent claim is also included for a device for operation of a coating-and/or printing device.
