The invention aims to provide an omni-directional intelligent furniture paint spraying robot. The omni-directional intelligent furniture paint spraying robot comprises an XYZ three-axis translational motion mechanism, a Y-axis rotating mechanism, a spraying gun, a supporting framework mechanism and the like; a Z-axis moving mechanism is mounted in a sliding way of a vehicle body through a sliding block on a Z-axis mounting plate, linear motion along a Z axis can be achieved through driving by screws and nuts, a Y-axis moving mechanism is mounted on the Z-axis mounting plate through a Y-axis mounting plate, linear motion along a Y axis can be achieved through driving by gears and racks, an X-axis moving mechanism is mounted on the Y-axis mounting plate through two polish rods, linear motion along an X axis can be achieved through driving by gears and racks, the Y-axis rotating mechanism is mounted on an X-axis sliding block through bolts, and rotating along the Y axis can be achieved through driving by a steering engine. By means of the omni-directional intelligent furniture paint spraying robot, space four-degrees-of-freedom movement of the spraying gun of the robot can be entirely achieved, omni-directional paint spraying can be performed on whole furniture, and defects that common paint spraying machines can only spray paint on panel plane furniture by fixed production lines, and the like can be overcome.
