    摘要: The present disclosure provides a method, device, and system for manufacturing a composite metal foil. The device includes: a first-time double-sided coating module and a second-time double-sided coating module that are arranged at an interval, where the first-time double-sided coating module includes: a first vapor deposition column and a second vapor deposition column that are arranged oppositely, and an unwinding roller, a first evaporation source, a first set of over rollers, a second evaporation source, and a second set of over rollers that are arranged sequentially from bottom to top on opposite surfaces of the first vapor deposition column and the second vapor deposition column; and the second-time double-sided coating module includes: a third vapor deposition column, and a first set of cooling rollers, a third evaporation source, a second set of cooling rollers, a fourth evaporation source, and a winding roller that are arranged sequentially from top to bottom on the third vapor deposition column. The sequential arrangement of the two evaporation sources and corresponding rollers from bottom to top on the opposite surfaces of the first vapor deposition column and the second vapor deposition column allows first-time double-sided coating, and the sequential arrangement of the two evaporation sources and corresponding rollers from top to bottom on the third vapor deposition column allows second-time double-sided coating, which can improve the site utilization and the film production efficiency.
