Abstract

The invention discloses an automatic abrasive blasting supplementing paint-removing method for aviation parts. The automatic abrasive blasting supplementing paint-removing method comprises the following steps that aviation parts after being subjected to abrasive blasting paint removing are subjected to real-time three-dimensional scanning by a robot with a three-dimensional visual sensor, and RGBDinformation is obtained; an industrial computer calculates color differences in the RGBD information and depth information of point cloud information with the color differences; D-H parameters and linkage coordinate system relations of the robot are put in robot paths by the industrial computer; the robot paths in the point cloud information with the color differences are connected by the industrial computer to form a whole robot run program; the whole robot run program is transmitted to an industrial robot by the industrial computer, and abrasive blasting paint removing of the portions, which are subjected to incomplete paint removing, of the aviation parts is carried out by the industrial robot according to the paths. According to the automatic abrasive blasting supplementing paint-removing method for the aviation parts, modeling and color recognition of workpieces after an abrasive blasting treatment are carried out through a RGBH three-dimensional sensor, the accuracy of judgmentis improved, and manual misjudgment is avoided.

Description

technical field [0001] The invention relates to the field of surface treatment of parts, in particular to a paint removal method for automatic respraying of aviation parts. Background technique [0002] In the current repair process of aviation parts, the method of sandblasting and paint removal by robots is usually used to remove the paint layer on the surface. However, due to the inhomogeneity of the paint layer of aviation parts, during the process of sandblasting and paint removal, some unremoved paint layers will remain on the surface of aviation parts, which greatly affects the quality of parts. Contents of the invention [0003] A kind of paint removal method for automatic repainting of aviation parts provided by the embodiment of the present invention comprises the following steps: [0004] S1: The robot carries a 3D vision sensor to perform real-time 3D scanning of the aviation parts after sandblasting and paint removal to obtain RGBD information; [0005] S2: T...
