The invention discloses a separation mechanism used for separating multiple stacked sheet-type magnetic conduction work-pieces. The separation mechanism comprises a magnet component and a support component arranged near the magnet component, wherein the magnet component comprises a holding part and at least a magnet fixed and contained in the holding part; the support component comprises a support part and a support rod fixed on the support part; the inner magnetic field direction of at least a magnet is parallel with the extension direction of the support rod; the holding part and the support rod are arranged at a preset distance to enable the multiple magnetic conduction work-pieces to slide sequentially along the two ends of the support rod under the action of the magnetic field of at least one magnet and further separate from each other.
