[0002] At present, for the coating operations of large-scale and complex structural workpieces such as the outer surface of aircraft, the inner surface of aircraft pipelines, and the outer surface of ships, most manufacturing companies use manual spraying. This spraying method has low coating efficiency and difficult coating quality. Guaranteed, and toxic paint mist seriously endangers human health
However, the current commercially available general-purpose six-degree-of-freedom spraying robot has a small working range, a large structural size, and low flexibility, and it is difficult to meet the spraying requirements of large-scale, complex curved surfaces, and narrow spaces.

The invention provides a seven-degree-of-freedom spraying robot which comprises a spraying gun and a robot body. The spraying gun is arranged at one end of the spraying robot body; the robot body comprises a base, a joint assembly, a connecting assembly for connecting between the joint assembly, and a spraying gun lengthening rod structure; the joint assembly comprises a first joint structure, a second joint structure and a third joint structure; the connecting assembly comprises a first connecting arm structure, a second connecting arm structure and a third connecting arm structure; the base,the first joint structure, the first connecting arm structure, the second joint structure, the second connecting arm structure, the third joint structure, the third connecting arm structure and the spraying gun lengthening rod structure are sequentially connected; and the other end of the base is fixed onto an external device. The seven-degree-of-freedom spraying robot provided by the invention adopts a modular design so as to be freely assembled into a multi-degree-of-freedom long arm structure, is large in working range, and can meet the requirement on spraying the outer surfaces of large-sized workpieces such as airplanes and ships.
Description
technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a seven-degree-of-freedom spraying robot. Background technique [0002] At present, for the coating operations of large-scale and complex structural workpieces such as the outer surface of aircraft, the inner surface of aircraft pipelines, and the outer surface of ships, most manufacturing companies use manual spraying. This spraying method has low coating efficiency and difficult coating quality. Guaranteed, and toxic paint mist seriously endangers human health. However, the current commercially available general-purpose six-degree-of-freedom spraying robot has a small working range, a large structural size, and low flexibility, and it is difficult to meet the spraying requirements of large-scale, complex curved surfaces, and narrow spaces. Contents of the invention [0003] In view of this, the present invention aims to propose a seven-degree-of-freedom spraying r...
