A servo stacking machine used on a for an aluminum ingot continuous castcontinuous casting production line for aluminum ingots comprises a movable mechanism and a lifting mechanism, wherein after aluminum ingot layers on a layer conveyor are well arranged, a servo motor (8) acts to drive a lifting mechanism (13) and a clamp (34) to drop to a layer whole-column station; the clamp (34) acts to clamp the whole layer of aluminum ingots; the servo motor (8) acts again to drive the lifting mechanism (13) and the clamp (34) to rise to an initial height; then a servo motor (25) acts to drive the movable mechanism to leftward move to right above a stacking station (44); and then the servo motor (8) acts again to drive the lifting mechanism (13), the clamp (34) and the aluminum ingot layer to drop. After the aluminum ingot layer is contacted with the stacking station (44), a transmission device (35) acts, and the clamp (34) is opened to place the aluminum ingots on the stacking station (44); next, the servo motor (8) acts, the lifting mechanism (13) rises to the initial height, the servo motor (25) acts to drive the clamp (34) to return the initial position, and a first layer of stacking is completed; and for a second layer of stacking, after a servo motor (33) acts to drive the clamp (34) and the second layer of aluminum ingots to rotate for 90 degrees, the second layer of aluminum ingots is placed on a first layer of aluminum ingots, and the stacking of the first layer of aluminum ingots is completed.
