Method for achieving one-time automatic spraying of colored paint multi-color gradient vehicle body robot

The invention relates to a method for realizing one-time automatic spraying of a colored paint multi-color gradient vehicle body robot, which comprises the following steps: color selection: a color replacement module is arranged in the robot, so that the color can be changed at any time, and a proper color is selected according to the color requirement of each part of a vehicle body; carrying out a wet distribution and wet matching experiment; the spraying range of each color is designed, specifically, the spraying range of each color is defined according to the spraying color requirement of each part of the vehicle body; a profiling track is compiled, specifically, a vehicle body spraying track is compiled, and the spraying track of each robot is compiled according to the range; track off-line simulation is carried out; vehicle model parameter configuration; carrying out online spraying simulation; spraying of the real vehicle is completed; baking is conducted after spraying is completed; modifying after bak
