Abstract: A flexible-rope-driven hybrid spray painting robot mechanism includes a static platform framework, a flexible-rope-guided pulley train, flexible transmission ropes, a moving platform, and drive mechanisms. A moving platform casing is driven by eight flexible ropes in parallel, to realize three degrees of freedom of translation thereof. A spray gun is connected in series to the moving platform casing via a universal joint cross, and is driven by four flexible ropes in parallel, to realize two degrees of freedom of rotation thereof. Beneficial technical effect of the present invention: The flexible ropes are used in parallel to control three degrees of freedom of translation and two degrees of freedom of rotation of the end spray gun, achieving advantages of a small movement inertia and flexible movement. Electric drive devices are placed together in a bottom layer of the static platform framework and are isolated from a spraying space.
