Reel-to-reel hot rolling forming device for fine structures of polymer thin film products

The invention relates to a reel-to-reel hot rolling forming device for fine structures of polymer thin film products. The device is characterized by comprising a frame, an unwinding module, a preheating module, a forming/shape-preserving module, a tensioning force adjusting module and a winding module, wherein the frame is mechanically connected with the preheating module, the forming/shape-preserving module and the tensioning force adjusting module; the tensioning force adjusting module is connected with the forming/shape-preserving module; being unwound by the unwinding module, a to-be-processed thin film substrate is heated by the preheating module, then enters into the forming/shape-preserving module for hot pressing and cooling formation, is imprinted, and is finally wound around the winding module. Compared with the prior art, the reel-to-reel hot rolling forming device has the advantages that the joint degree between the substrate and a mould during shape preserving and cooling processes is enhanced; the microstructure resilience on the surface of a thin film is reduced; the forming precision is improved; and suitability for mass production of large-area thin film devices is achieved.
