Optimization method for thickness uniformity of irregular planes and polygonal coating layers by electrostatic spraying robot

Abstract

The invention discloses an optimization method for the thickness uniformity of irregular planes and polygonal coating layers by an electrostatic spraying robot. Firstly, a spraying gun trajectory mathematical model is built; then, a space distribution model of paint, a translation schematic diagram of a static-state distribution model and a section thickness chart of a translation model are built;according to comparison with data obtained by a double-variable Cauchy distribution model, a double-variable Gaussian distribution model and an offline experience, a traditional elliptical double-beta model is finally built; and finally, the spraying joint is performed for multiple times of spraying, that is, the thickness uniformity of paint films is improved through selection of a gap d betweentravels.

Description

technical field

[0001] The invention relates to a method for spraying irregular polygons by a spraying robot, which is mainly aimed at optimizing the uniformity of coating thickness. Background technique

[0002] Electrostatic spraying is a new technology based on the combination of traditional spraying and electrostatic effect. Applying electrostatic spraying technology to spraying robots has the best economic benefits and is widely used in domestic and foreign automobile coating production lines. It not only improves the quality of products Quality and output, but also to ensure personal safety, improve working conditions, reduce labor intensity, reduce production costs and reduce environmental pollution. In the robot spraying process, the uniformity of the coating thickness on the surface of the workpiece directly affects the spraying quality of the workpiece. If the uniformity does not meet the target, re-painting may be required, which will not only cause waste of paint...
