[0002] Lithium batteries are batteries that use lithium metal or lithium alloy as anode materials and non-aqueous electrolyte solutions. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] The existing lithium battery pole piece chamfering device, when performing chamfering processing on the lithium battery pole piece, mostly needs to use a slitting machine to cut the battery pole piece to size, and then place the cut battery pole piece on the chamfering device for chamfering processing, which makes the processing procedure more complicated and the processing efficiency is relatively low. For this reason, we propose a lithium battery pole piece chamfering device. Utility Model Content

Corner knives 9 are fixedly provided at both ends of the knife 8. The corner knife 9 is a herringbone structure. The end faces of the corner knife 9 and the cross-cutting knife 8 are both triangular structures. The distance between the end points of the corner knives 9 at both ends of the cross-cutting knife 8 is the same as the width of the lithium battery pole piece. The cross-cutting knife 8 at the bottom of the knife holder 6 can cut the lithium battery pole piece, and the corner knives 9 at both ends of the cross-cutting knife 8 can chamfer the cut lithium battery pole piece, so that chamfering can be performed when the lithium battery pole piece is cut, reducing the complexity of the processing procedure and improving the processing efficiency of the lithium battery pole piece.

[0022] like Figure 1 and Figure 2As shown, detectors 10 are fixedly provided on the top of the two mounting plates 1, guide assemblies are installed on the top of the two mounting plates 1, a frame 11 is fixedly provided between the two mounting plates 1, a motor 12 is fixedly provided at the bottom of the frame 11, a ball screw 13 is fixedly provided at the output end of the motor 12, the end of the ball screw 13 is connected to the guide assembly, a slider 15 is threadedly connected to the circumferential outer wall of the ball screw 13, a placement plate 14 is fixedly provided on the top of the slider 15, the placement plate 14 is connected to the guide assembly, and the outer wall of the placement plate 14 is a symmetrical structure with two adjustment assemblies installed.
