[0038] In the embodiment, the workpiece is a pole piece 100, and in other embodiments, the workpiece can also be other structures that need to be die cut.

[0039] The conveying mechanism 40 comprises a support roller 42 and a conveying piece 41 for supporting the die-cut polar piece 100. The support roller 42 is rotationally arranged on the rack 30 and is used to support the conveying piece 41 to ensure the supporting and conveying effect on the polar piece 100.

[0040] It should be noted that the die-cut mechanism 20 and the conveying mechanism 40 are common structures of the die-cut device, and will not be specifically introduced in the embodiment.
