Round corner cutting device for lithium battery pole piece

Abstract

The invention discloses a round corner cutting device for a lithium battery pole piece. The round corner cutting device for the lithium battery pole piece comprises a support body (1), an upper cutting die (2) and a lower cutting die (3). The upper cutting die (2) is slidably installed on the support body (1) and correspondingly located above the lower cutting die (3). The lower cutting die (3) isarranged at the inner bottom of the support body (1). The upper cutting die (2) is provided with an upper cutting knife (4). The lower cutting die (3) is provided with a cutting knife positioning groove (6) and a cutting table (9) corresponding to the upper cutting knife (4). The cutting table (9) is arranged at the groove edge of the cutting knife positioning groove (6). According to the round corner cutting device for the lithium battery pole piece, during the cutting process of the lithium battery pole piece, the cutter forming force is effectively reduced, the cutter service life is prolonged, cutter sideslipping is prevented, cutting burrs are reduced, and the problem of incomplete cutting is solved, a plurality of combined cutting mechanisms can be simultaneously used for synchronous cutting, and the cutting efficiency of the lithium battery pole piece is effectively improved.

Description

technical field [0001] The invention relates to the field of battery pole piece cutting equipment, in particular to a lithium battery pole piece fillet cutting device.

The large-scale application of lithium batteries in rapidly growing consumer electronics and other electronic products ha...

AI Technical Summary

Problems solved by technology

The efficiency of manual cutting with scissors is low and cannot meet the needs of industrial production

However, if the existing lithium battery pole piece fillet cutting device is used for cutting, the cutting knives all adopt parallel knife edges, which is easy to cause the problem that the cutting tool forming force is too large and the tool life is short; and the cutting tool and the cutting table cannot be completed. Effective alignment, and at the same time, the cutting tool and the cutting table cannot be effectively bonded during the cutting process, which is likely to cause problems such as side slipping of the tool, burrs generated by cutting, and continuous cutting, which seriously affects the pass rate of the product and is not conducive to the improvement of lithium battery production efficiency.
