High-flexibility six-degree-of-freedom spraying robot

Abstract

The invention discloses a high-flexibility six-degree-of-freedom spraying robot. A base assembly serves as a basis of a spraying robot, and the lower end of the base assembly is fixed on the ground ora workbench through screws; a head port of a waist joint assembly can be connected to an upper port of the base assembly by rotating along the horizontal plane; a head port of a large-arm joint assembly can be connected to a tail port of the waist joint assembly by rotating along the vertical plane; a head port of a small-arm joint assembly can be connected to a tail port of the large-arm joint assembly by rotating along the vertical plane; a head end of a three-degree-of-freedom hollow wrist is fixed on a tail end of the small-arm joint assembly, and a tail end of the three-degree-of-freedomhollow wrist is fixedly connected with an electrostatic spinning cup spray gun; and the base assembly, the waist joint assembly, the large-arm joint assembly and the small-arm joint assembly are hollow structures and jointly form a sealing cavity of the spraying robot, an internal wiring pipe is arranged in the sealing cavity, and a first external wiring pipe is arranged on the outer side of thespraying robot. According to the invention, the motion flexibility and flexibility are good, and the application range of the spraying task can be wide.

Description

Problems solved by technology

However, the same three-degree-of-freedom offset wrist is used in the above-mentioned solutions, and the configuration is relatively simple, and the flexibility of the robot is not high; moreover, the spraying robot has no installation space for spraying system components such as gear pumps, color-changing valves, and valve islands. And the structure, the paint pipe and air pipe are connected to the spray gun through a long distance, which is not conducive to improving the response speed of the spray system, and the paint waste is serious when changing colors
