[ background of the utility model ]

The flexible wiring board is also called as an FPC board or a flexible board. An electronic product with a mobile phone/a computer as a terminal has an internal flexible circuit board which is one of the main core parts of the electronic product. To meet the design requirements of small and high density mounting, reduce assembly processes and reinforcement, a flex is required to provide superior electrical performance and signal transmission for the device. In order to meet the requirements of electrical performance and signal transmission, the flexible board is manufactured by using copper foil as a base material through various processes. However, the flexible board using copper foil as the substrate is easy to have electrostatic breakdown phenomenon during the manufacturing and using processes. In order to prevent the flexible board from being defective due to electrostatic breakdown, it is a common practice to attach protective films (which have insulating properties) to both sides of the flexible board. In the prior art, during the design and production process of the protective film, since some specific areas of the flexible board cannot be covered, the protective film is required to be punched to form a larger opening in the specific area. When roll stock protective film is rolled after punching, such protective films with large openings may cross each other in the opening area, resulting in wrinkles and even tears. Therefore, it is necessary to research a winding mechanism for a flexible board coating film and a coating device having the winding mechanism.
