The invention relates to an electric robot control system for paper pile dismounting. The system comprises a paper pile dismounting station, a board dismounting station and a pallet dismounting station; the paper pile dismounting station comprises a robot unit, a pile dismounting unit, a board collecting unit, a cardboard collecting unit and a pallet collecting unit; and the robot unit comprises a gripper, a coordinate photoelectric pile detecting unit and a front and back side identification detecting unit. All motions in paper pile dismounting are provided, and the paper pile can be dismounted automatically. The external structure of the cardboard can be identified to select a grabbing direction; the front and back sides of the cardboard are distinguished by colors to determine whether to overturn the cardboard; the board and a separator plate which are laid on the paper pile during feeding can be absorbed; the residual empty pallet after paper pile dismounting can be grabbed; and workers need not to climb up to carry out dismounting, and the labor intensity is reduced greatly.
