Intelligent spraying robot system and spraying method thereof

Abstract

The invention provides an intelligent spraying robot system and a spraying method thereof. The intelligent spraying robot system comprises a scanning modeling unit, an offline programming unit, a driving control unit, a robot body, and a thickness detection unit. The scanning modeling unit performs three-dimensional scanning and modeling on a workpiece to obtain model data; the offline programming unit generates a spraying track according to the model data; the driving control unit drives a spray gun on the robot body to move according to the spraying track and conduct spraying operation on the workpiece; the thickness detection unit detects coating thickness data and feeds back the coating thickness data to the driving control unit; and the driving control unit calibrates spraying process parameters according to the detection data. According to the intelligent spraying robot system, the spraying track is generated through three-dimensional scanning modeling, the intelligent spraying robot system is suitable for the spraying of various workpieces, and the precision of the spraying track is high; and a spraying process parameter error calibration mechanism is introduced through coating thickness detection, so that spraying quality problems caused by spraying track errors, spraying process parameter errors and other errors are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent spraying, in particular to an intelligent spraying robot system and a spraying method thereof. Background technique [0002] The use of spraying robots in the spraying industry can avoid artificial long-term exposure to toxic and harmful production environments. The spraying robot uses the manual teaching method or the off-line programming method to generate the spraying trajectory, and commands the robot to carry out the spraying operation according to the spraying trajectory. The manual teaching spraying robot sprays after manual teaching. Workpieces with different appearances need at least one manual teaching respectively. The efficiency of spraying is low, and the spraying quality is limited by the spraying level of the teaching workers. If it is large, the spraying quality is not high; at the same time, considering the slight fluctuation of the spraying process parameters or the error of...

Problems solved by technology

The manual teaching spraying robot sprays after manual teaching. Workpieces with different appearances need at least one manual teaching respectively. The efficiency of spraying is low, and the spraying quality is limited by the spraying level of the teaching workers. If it is large, the spraying quality is not high; at the same time, considering the slight fluctuation of the spraying process parameters or the error of the spraying track itself, if the spraying operation is still carried out according to the preset spraying process parameters, the quality of the coating formed by spraying is as follows: If the thickness and surface smoothness of the coating cannot be effectively controlled, the spraying quality of this spraying is not high, and it may need to be reworked or even discarded. The spraying efficiency is relatively low and the cost is wasted
