摘要： Provided is a roll-to-roll copper foil laminating device. The device comprises a dry film holder shaft, a copper foil holder shaft, and a dry film roll connected to the dry film holder shaft; an outer surface of the copper foil frame shaft is wound with a copper foil roll. Before the dry film roll contacts a diffuser roller, the dry film roll goes through an EPC correction structure and remain in a state of active bonding; the distance from the dry film roll to the diffuser roller is 1.5 times a distance from the copper foil roll to the diffuser roller; a rotation axis of the dry film holder shaft and a rotation axis of the copper foil holder shaft move synchronously with an outer spin column.
