Description

technical field

[0001] The invention relates to a method for automatically optimizing the trajectory of a spray gun of a spraying robot, which is an off-line programming method for a robot when performing a spraying operation on a workpiece whose surface is a complex curved surface. Background technique

[0002] The spraying effect of the spraying robot is related to many factors such as the surface shape of the object and the parameters of the spray gun. For products such as automobiles, electrical appliances and furniture, the spraying effect on the surface has a considerable impact on the quality. In the automatic spraying operation, the manipulator of the spraying robot moves back and forth around the surface of the workpiece to be painted, and the selection of appropriate trajectory and other process parameters can save production costs and correspondingly reduce the total amount of paint discharged into the spray shop environment. amount and reduce environmental pollu...
