The invention relates to the field of storage battery manufacturing, and discloses an energy storage battery automatic rotating device. A rotating assembly and a transmission assembly are arranged onthe base, the transmission assembly is located above the rotating assembly, a servo motor is fixed to a base in the rotating assembly, an output shaft of the servo motor is connected with the rotary shaft, crossed rotary blocks coaxially sleeve and are fixed to the rotary shaft, transmission shafts in the transmission assembly are located above the crossed rotary blocks and perpendicularly arranged on the rotary shaft, each crossed rotary block is located between every transmission shafts, and the top of the crossed rotary block is higher than the plane where each transmission shaft is located; an inlet rail and an outlet rail are perpendicular to the transmission shafts and are located on opposite side positions of the two ends of each transmission shaft. The device has the advantages that a storage battery can be automatically rotated, the rotating action is stable, the impact on the side face of the storage battery at the moment the battery is rotated and placed up side down, the quality of the battery is not influenced, the rotation efficiency is higher, and labor force is saved.
