Reel-to-reel multifunctional printing equipment used for printing electronics and application thereof

The invention discloses reel-to-reel multifunctional printing equipment used for printing electronics and application thereof. The reel-to-reel multifunctional printing equipment comprises a cleaning unit, a corona treatment unit, a deviation rectifying unit, a micro gravure printing unit, a slit coating unit, a drying unit, a silk-screen printing unit and a composite unit. The micro gravure printing unit, the slit coating unit, the silk-screen printing unit and the composite unit in the reel-to-reel multifunctional printing equipment can be managed in a modularized mode, can work independently, and can also be connected in series to work simultaneously for printing and manufacturing multi-layer functional films. The reel-to-reel multifunctional printing equipment is suitable for being used for manufacturing the functional films and photoelectric devices through solution-method printing and processing, and particularly suitable for being used for manufacturing flexible electronic devices based on semiconductor films, wherein the flexible electronic devices comprise organic solar cells, organic light-emitting diodes, organic field effect transistors and the like.
