The invention belongs to the technical field of automatic material separation, and particularly relates to an intelligent production material separator used for rapidly separating paperboard piles from trays. The separator comprises a feeding conveying table, a lifting table and a discharging conveying table. The lifting table has a high position state and a lower position state. When the liftingtable is in the high position, a table top, used for holding the paperboard piles and the trays, of the lifting table and the conveying face of the feeding conveying table are located on the same plane; when the lifting table is in the low position, the table top of the lifting table is lower than the conveying face of the discharging conveying table, and the vertical distance between the table top of the lifting table and the conveying face of the discharging conveying table is equal to the height of the trays; and a gap allowing a paper pushing baffle to be put in in the vertical direction exists between the lifting table and the feeding conveying table. The intelligent production material separator has the advantages of being high in automation degree and operation reliability, compactin structure and easy, convenient and rapid to operate, and the on-line separation operation of the paperboard piles and the trays can be achieved efficiently.
