The invention discloses a production process of a unipolar plate used for a fuel battery. Through a continuous stamping die, a raw material can be continuously subjected to punching, hole turning ribpressing, side cutting and puncturing, rough forming, fine forming and separating in the punching process, the raw material can be continuously punched and formed, time discontinuity of stamping of the single procedure can be avoided, the production efficiency of the unipolar plate can be improved, and meanwhile, the unipolar plate finished product consistency can be improved; a mechanical arm isused in multiple stations for grabbing, ultrasonic cleaning, laser coding, visual detecting, and reciprocated framing are sequentially carried out, manual participation of the unipolar plate from theraw material to framing is not needed, manual cost is greatly reduced, the product production quality and the product yield can be improved, through the mechanical arm, the defective products output through visual detection are conveyed to an NG worktable, disqualified products are removed, the inferior-quality unipolar plate can be prevented from entering the follow-up processing procedure, resource waste is reduced, and the yield of finished products is increased.
