The invention discloses an automatic identification plate overturning device for composite floor production, and belongs to the field of floor processing equipment. The automatic identification plateturnover device includes an integrated frame, an automatic identification plate turnover mechanism, a floor conveying mechanism, an air pressure driving mechanism and a control system, the plate overturning mechanism is rotatably connected in the inner part of the integrated frame, the air pressure driving mechanism and the automatic identification plate overturning mechanism are connected, and the start and stop of the automatic identification plate overturning mechanism and the air pressure driving mechanism are controlled through the control system. According to the automatic identificationplate overturning device for the composite floor production, the automatic identification plate overturning device for the composite floor production can be matched with a feeding mechanical hand containing an air pressure hoisting device, front and reverse placement of wood floors can be automatically identified, composite floors placed on reverse side are automatically identified, thus plate overturning is conducted on the composite floors, artificial identification on plate overturning operation is not needed, the large amount of the manpower resources is saved, design is smart and reasonable, and work is safe and reliable.
