Abstract
This application provides a winding and unwinding device and a battery production system. The winding and unwinding device includes a turret, a driver, and a magnetic powder clutch. The turret includes a rotation shaft and at least one winding shaft, the rotation shaft being parallel to the winding shaft. A drive shaft of the magnetic powder clutch is connected to the driver and a driven shaft of the magnetic powder clutch is connected to the rotation shaft of the turret, such that the driver drives the rotation shaft of the turret to rotate. In this application, with the magnetic powder clutch disposed between the turret and the driver, after the turret rotates to a predetermined position, the rotation of the turret can be stopped without the need to cut off the power supply, ensuring the normal operation of the driver when the turret stops rotation, thus avoiding damage to the driver.
