Abstract
This application relates to a winding and unwinding apparatus and a preparation system of electrode plate. The apparatus includes supports, a rotating shaft, a rotating turret, and a power assembly. The rotating shaft is rotatably disposed on the support. The rotating turret is disposed on the rotating shaft and capable of rotating along with the rotating shaft so as to switch between at least two target operation positions. The power assembly includes a first power source and a magnetic powder clutch. The rotating shaft and the first power source are in transmission connection with each other via the magnetic powder clutch. The magnetic powder clutch is configured to control the rotating shaft to remain stationary when the rotating turret is hovering at each target operation position.
