The invention discloses a multi-station reinforcing sheet laminating device for flexible circuit board production, which comprises a fixing support, and is characterized in that a welding bottom plateis fixedly connected between two side walls of the bottom end of the fixing support, a workbench is arranged at the upper end of the welding bottom plate, a plurality of sliding grooves are evenly formed in the surface, which is away from the welding bottom plate, of the workbench, a first sliding block is slidably connected in each sliding groove, the upper end of the first sliding block is fixedly connected with a first connecting rod, and a movable carrier plate is arranged above the workbench. According to the invention, the movable carrier plate is arranged and is matched with an electric sucker, so that the reinforcing sheet can be fed, the manual feeding is avoided, the manual labor time is saved, and the production cost of the factory is reduced. Meanwhile, compaction rollers aredriven down by a single-track servo electric cylinder, and the laminating effect of the reinforcing sheet can be increased under the movement of the movable carrier plate. The mechanism adopted in thedesign is simple, high in efficiency and easy to repair and maintain, the workload of workers can be reduced, and the laminating operation efficiency is greatly improved.
