Embodiment 1

[0043] A kind of intelligent robot spraying method based on spraying system, comprises the following steps:

[0044] 1) Obtain the three-dimensional model of the workpiece to be sprayed;

[0045] 2) Generate the corresponding initial spraying trajectory according to the three-dimensional model of the workpiece to be sprayed;

[0046] 3) Optimize the relevant parameters of the robot according to the initial spraying trajectory;

[0047] 4) Set the coordinate system on the robot so that the spraying trajectory coordinate system on the three-dimensional model of the workpiece to be sprayed is consistent with the coordinate system of the spray gun to generate the final spraying trajectory;

[0048] 5) The final spraying trajectory is transmitted to the robot controller, and the controller controls the spraying robot to complete the automatic spraying operation requirements according to the processing results.

[0049] In the preferred version of this embodiment, the method also ...

Embodiment 2

[0065] This embodiment should be understood as at least including all the features of any one of the foregoing embodiments, and is further described on the basis of it:

Abstract

The invention provides an intelligent robot spraying method based on a spraying system. A machine is adjusted through a spraying process library instead of a machine adjustment process library; for different workpieces to be sprayed, a spraying trajectory program can be automatically identified and generated; and an optimal spraying parameter and an optimal spraying trajectory are selected according to the built spraying process library. Compared with traditional spraying, after applying the method provided by the invention, the spraying quality and the spraying efficiency of workpieces are improved, meanwhile, the dosage of a spraying coating is relatively reduced, and for a determined spraying trajectory, trajectory optimization is carried out on relevant parameters such as the sprayingspeed and the spraying flow of a spraying robot by adopting the spraying uniformity as an optimal object, so that the spraying quality can achieve the best effect.

Description

technical field [0001] The invention relates to the field of spraying, in particular to an intelligent robot spraying method based on a spraying system. Background technique [0002] The competition in the field of industrial spray production is becoming increasingly fierce, with increasing demands on the level of automation, optimization and quality of the paint. The introduction of industrial robot spraying system will be more environmentally friendly, energy-saving, healthy and safe, and will greatly reduce costs. The robot path plays a decisive role in the uniformity of spray thickness, which in turn strongly affects the quality of its products. [0003] The generation method of the robot spraying path is generally completed by the debugger after the 3D drawing of the workpiece to be sprayed and the on-site teaching and programming many times. This method is complicated to operate, requires high professional skills for the operator, and has poor flexibility. After the ...
