[0032] Moreover, the positioning convex part 220 can also avoid the position deviation of the material sheet 400 when the material sheet stacking device collides or shakes during operation.

[0033] In the scheme, the material sheet 400 is a magnetic material sheet 400 made of material that can be suctioned by the magnetic part 210, for example but not limited to the material itself having ferromagnetic property, the material containing ferromagnetic component, the material adding magnetic additive or containing magnetic particles.

[0034] In the embodiment, further, the material taking structure 200 comprises an inner core 230, an outer cylinder 240 and a magnetic driving structure 250, the outer cylinder 240 is rotationally arranged on the mounting base 100, the alignment driving structure 300 is drivingly connected with the outer cylinder 240, the outer cylinder 240 has a material taking wall 241, the magnetic member 210 is arranged on the inner core 230, the inner core 230 is slidingly arranged in the outer cylinder 240 along the axial direction of the outer cylinder 240, and the magnetic driving structure 250 is drivingly connected with the inner core 230 to drive the inner core 230 to slide towards the direction close to or away from the material taking wall 241. It can be understood that the magnetic driving structure 250 drives the outer cylinder 240 to rotate so that the positioning protrusion 220 is aligned with the positioning hole of the material sheet 400, the magnetic driving structure 250 drives the inner core 230 to slide towards the direction close to the material taking wall 241, so that the magnetic member 210 is close to the material sheet 400, thereby attracting the material sheet 400 to the material taking wall 241, at this time, the positioning protrusion 220 is arranged in the positioning hole, finally, the material sheet stacking device is moved to the material placing position, so that the material sheet 400 is aligned with the material placing position, the magnetic driving structure 250 drives the inner core 230 to move away from the material taking wall 241, that is, the magnetic member 210 moves away from the material sheet 400, thereby demagnetizing the material sheet 400, the material sheet 400 slides along the positioning protrusion and falls on the material placing position, thereby realizing the coaxial stacking of the plurality of material sheets 400. Of course, the present scheme is not limited to this, and in other embodiments, the material taking structure 200 can also comprise a material taking shaft, the positioning protrusion 220 is arranged on the end face of the material taking shaft, and the magnetic member 210 is configured as an electromagnet, the electromagnet is arranged on the material taking shaft, when it is needed to attract the material sheet 400, the power supply of the electromagnet is connected to magnetize and charge the electromagnet, so that the material sheet 400 can be attracted to the end face of the material taking shaft, at this time, the positioning protrusion 220 is arranged in the positioning hole of the material sheet 400. When it is needed to place the material sheet 400 on the material taking wall 241 to the material placing position, the power supply is disconnected to demagnetize the electromagnet, so that the material sheet 400 slides to the material placing position.

[0035] Further, in the embodiment, the outer cylinder 240 is rotationally arranged on the mounting base 100 through a bearing, because the bearing can reduce the friction between the outer cylinder 240 and the mounting base 100, thereby reducing the energy loss and improving the mechanical efficiency.

Specifically, the alignment drive structure 300 drives the outer cylinder 240 to rotate, so that the avoiding through hole is aligned with the positioning hole of the material sheet 400. Since the circumferential limiting structure 260 is arranged between the outer cylinder 240 and the inner core 230, the inner core 230 will also rotate synchronously at this time, and the positioning protrusion 220 will also be aligned with the avoiding through hole and the positioning hole of the material sheet 400. Then, the outer cylinder 240 is driven to abut against the material sheet 400, and the magnetic drive structure 250 is controlled to drive the inner core 230 to move towards the direction close to the material taking wall 241, so that the positioning protrusion 220 is sequentially inserted into the avoiding through hole and the positioning hole of the material sheet 400, and the material sheet 400 is also attracted to the material taking wall 241. Aligning the avoiding through hole with the positioning hole of the material sheet 400 first, and then sequentially inserting the positioning protrusion 220 into the avoiding through hole and the positioning hole of the material sheet 400, can avoid interference between the positioning protrusion 220 and the material sheet 400.
