The invention discloses a parallel-connection sorting robot provided with a double movable platform structure. The parallel-connection sorting robot comprises a stationary platform, a movable platform component and four branch chains, wherein the four branch chains are connected between the stationary platform and the movable platform component. Four driving devices are mounted on the stationary platform and arranged in a circumferentially-symmetrical manner. The movable platform component is composed of an upper movable platform, a lower movable platform, sliding guide rails, a motion conversion mechanism and a tail end actuator. Rotation of the four driving devices is controlled, and three movement freedom degrees and one rotation freedom degree of the tail end actuator can be achieved. The parallel-connection sorting robot provided with the double movable platform structure has the beneficial effects of being compact in structure, flexible in motion, easy to control, good in rigidity and stability and the like.
