Abstract
A micro-lens array fabrication apparatus includes a first roller, a second roller, a molding member, and a cooling member. The first roller and the second roller revolve cooperatively to position portions of a substrate on the molding member while maintaining a tension on the substrate. The molding member includes a shaft and two caps connected to opposites ends of the shaft. The shaft defines a through hole and rows of molding holes in a lateral surface thereof, and forms heaters in the though hole. The heaters heat up the substrate till molten, and the air is driven to blow the molten substrate into the molding holes and form a row of micro-lens structures on the currently positioned portion of the substrate.
