In the present embodiment, the lateral driving member 24 is a driving cylinder; the tail end of the driving cylinder is fixedly connected with the protective film pickup piece 23 and drives the protective film pickup piece 23 to transversely reciprocate; in other embodiments, a higher precision transverse module or cylinder may be used.

When picking up the protective film 8, each of the lateral driving members 24 drives the corresponding protective film pickup pieces 23 to approach each other, reducing the distance between the protective film pickup pieces 23; when attaching the protective film 8, each of the lateral driving members 24 drives the corresponding protective film pickup pieces 23 away from each other, increasing the distance between the protective film pickup pieces 23; thus, in this embodiment, five transverse driving members 24 are required, which is costly and complicated to control.

In order to make the distance adjustment between the protective film pickups 23 more stable, a first lateral guide rail may be mounted on the first mounting plate 22, on which the protective film pickups 23 are mounted, along which the protective film pickups 23 reciprocate laterally under the drive of the corresponding lateral driving members 24.

Further, a linkage part 3 is arranged between the protective film pickup pieces 23, and a transverse driving part 24 is fixedly connected with the protective film pickup pieces 23 at the right end and drives the protective film pickup pieces 23 to move leftwards and transversely, and drives other protective film pickup pieces 23 to move leftwards and transversely together through the linkage part 3, so that the distance between the protective film pickup pieces 23 is adjusted.

Specifically, when the protective film 8 is picked up, the transverse driving component 24 drives the protective film pickup pieces 23 to move leftwards and transversely, and drives other protective film pickup pieces 23 to move leftwards and transversely together through the linkage component 3, so that the protective film pickup pieces 23 are mutually close to each other, and the distance between the protective film pickup pieces 23 is reduced; the transverse driving part 24 drives the protective film pickup pieces 23 to move transversely to the right, and drives other protective film pickup pieces 23 to move transversely to the right together through the linkage part 3, so that the protective film pickup pieces 23 are far away from each other, and the distance between the protective film pickup pieces 23 is increased.

Further, when the protective film pickup 23 is lowered to two, the linking member 3 may not be used; one of the protective film pickup pieces 23 is fixed on the U-shaped mounting plate so as not to be movable; the other protective film pickup 23 reciprocates laterally by the drive of the lateral drive member 24, thereby adjusting the distance between the two protective film pickup 23.
