  • Patent number: 12120828
    Abstract: A reel mechanism and a winding device for a flexible copper clad laminate includes a rotating roller, a winding belt wound on the rotating roller for winding the flexible copper clad laminate, first and second limit structures arranged one side of the winding belt away from the rotating roller. A space between the first limit structures and the second limit structures accommodates the flexible copper clad laminate. When the winding belt is wound with multiple layers outside the rotating roller, adjacent layers of the winding belt are spaced apart by the first and second limit structures. Since a protruding height of the first limit structures is equal to a protruding height of the second limit structures, and intervals between adjacent layers of a composite coil formed by the winding belt and the flexible copper clad laminate are equal, which avoids adhesion and copper foil surface oxidation.
