The utility model relates to a device for coating a PET (polyethylene terephthalate) film with a copper layer, which comprises a vacuum box and an evaporation mechanism, an unwinding roller and a winding roller are mounted on the inner side wall of the vacuum box, and a first guide roller and a second guide roller are further mounted on the inner side wall of the vacuum box. The first guide roller and the second guide roller are located on the upper side of the unwinding roller and the upper side of the winding roller respectively, and a PET film sequentially passes through the first guide roller and the second guide roller from the unwinding roller and then returns to the winding roller. The evaporation mechanism comprises a first evaporation piece and a second evaporation piece which are located on the two sides of the PET film correspondingly, and the first evaporation piece and the second evaporation piece are installed at the output end of a first telescopic mechanism and the output end of a second teles
