Impregnation device for fiber prepreg and method thereof

An impregnation device for a fiber prepreg, comprising:

• a film layer separator, comprising:
• a first roller;
• a film layer receiver disposed over the first roller;
• and
• a second roller disposed between the film layer receiver and the first roller in a vertical direction, and a separation angle between a direction of the first roller facing the film layer receiver and a direction of the first roller facing the second roller being greater than 0°;
• a resin film provider disposed over the first roller, and when projected vertically on a horizontal plane where the first roller is located, the resin film provider and the film layer receiver being respectively located at opposite sides of the first roller, wherein the horizontal plane where the first roller is located is perpendicular to the vertical direction;
• a fiber provider disposed beneath the film layer separator;
• a hot pressing processor disposed beneath the film layer separator in the vertical direction;
• and
• a thermal barrier disposed between the film layer separator and the hot pressing processor in the vertical direction, wherein the thermal barrier comprises an insulating material and is arc-shaped, and a concave shape of the thermal barrier only faces the hot pressing processor to converge heat at a side of the hot pressing processor.
