DESIGN OF A PAINTING ROBOT WITH HOLLOW NON-SPHERICAL WRIST

Abstract

Painting robot is one of the key systems for automobile manufacturing, thus its structural design and safety check have significant value in industrial circles. To facilitate the layout of pipeline and reduce the bending of pipe, a painting robot with hollow non-spherical wrist is presented in this paper. Based on the overall structure scheme of the painting robot, the transmission path in the hollow non-spherical wrist is analyzed, and the transmission ratio of each kinematic pair is calculated. Then, the 3D model of the painting robot is established using Solid Works, and the safety check of main arm and forearm is done using Ansys. The research of the painting robot with hollow non-spherical wrist will lay good foundation in further research of painting robot.
