The utility model discloses a fully automatic vacuum rewinding machine. The fully automatic vacuum rewinding machine comprises a case which is internally provided with a vacuum box, and is characterized in that a vacuum sealing door, a vacuum system and an automatic control box are arranged on the outer part of the case; the vacuum box is internally provided with at least two power drive rollers, multiple unpowered driven rollers and a heater. The fully automatic vacuum rewinding machine breaks through the technical bottleneck of traditional vacuum drying, so that a material coil can be subjected to vacuum drying in an unfolding state; therefore, drying consistence of the material is not only ensured, equipment floor space, electric energy consumption and labor cost are also reduced efficiently, and the purpose of saving energy comprehensively is realized. As automatic control is adopted, heating time is shortened efficiently and production efficiency is improved greatly. The demands on drying the battery material coil can be satisfied only by taking time which is about 1/15 of the original time for one-time drying and using the electric energy consumption which is only 1/10 of the original electric energy consumption.
