ROLL REPLACING DEVICE

The application relates to a coil replacing device. Material tapes output by a first unreeling assembly and a second unreeling assembly can be alternately used as a working materials tape and a spare materials tape. When the unreeling of the working material tape by the first unreeling assembly is about to be finished, a first cutting assembly cuts off the working material tape fixed by a fixing mechanism and a first positioning assembly, and by moving the fixing mechanism relative to the first positioning assembly in a first direction, the spare material tape unreeled by the second unreeling assembly can be aligned with the working material tape fixed by the first positioning assembly. Then, a swing assembly drives an adhesive attaching driver to swing from an adhesive preparation position to an adhesive attaching position, and an adhesive attaching mechanism drives two suction plates to be folded, so that adhesive pieces can be attached to the aligned spare material tape and working material tape, thus connecting the spare material tape with the working material tape to form a new working material tape, and a new reel can be loaded onto the first unreeling assembly to serve as a spare material tape. In this way, the coil replacing device can realize automatic coil replacing, and coil replacing efficiency is high.
