Abstract: An automatic high-speed stacking machine is disclosed, including a loading unit, a precision positioning unit, a stacking unit, a grabbing unit and a feeding unit. The feeding unit includes a platen configured to place silicon steel sheet stack; a material warehouse configured to store the platen containing the silicon steel sheet stack. An area of a side of the material warehouse is defined as a reclaiming area, and an area of a side of the loading unit is defined as a loading area. A skip car moving back and forth between the reclaiming area and the loading area is configured to take out and send the platen containing the silicon steel sheet stack from the material warehouse to the loading area, or send an empty platen back to the material warehouse.
