The invention discloses an automatic lamination production line for plates. The automatic lamination production line for plates comprises a first drum-type conveying line, a second drum-type conveying line arranged right above the first drum-type conveying line by virtue of a top plate, a nozzle unit which is arranged on the second drum-type conveying line and used for spraying a binder towards the plates on the first drum-type conveying line, a baffle unit which is arranged at the discharge end of the second drum-type conveying line and under the first drum-type conveying line, a supporting unit arranged close to the discharge end of the first drum-type conveying line and a down-pressing unit, wherein the supporting unit is arranged under the first drum-type conveying line, the down-pressing unit is arranged right above the first drum-type conveying line by virtue of the top plate, and the supporting unit and the down-pressing unit are matched each other to complete lamination of the plates. The automatic lamination production line for plates has the advantages that labor intensity of workers can be reduced and plate lamination working efficiency and lamination quality are effectively improved.
