Utility model content
The purpose of this utility model is, the pole piece shaped device that provides a kind of lithium ion battery to use.The utility model perfection has solved the problem that cannot align with pole piece cutting die upper edge in the coating portion upper edge of pole piece collector, has improved widely the accuracy of pole piece punching press, has finally reduced defect rate; Meanwhile, the utility model has improved the production efficiency of pole piece widely, is applicable to industrial mass production.
The technical solution of the utility model: the pole piece shaped device that a kind of lithium ion battery is used, comprise cutting die mainboard, cutting die mainboard is provided with one group of pole piece cutting die, and the both sides of pole piece cutting die are respectively provided with cornerite, the inboard of cornerite is provided with side groove, and aligns with the upper edge of pole piece cutting die in the lower edge of cornerite.
Above-mentioned device, the width of described cornerite is identical with the metal portion width of pole piece collector.
Aforesaid device, described cornerite comprises fixed block, the inner side of fixed block is provided with side groove; Align with the upper edge of pole piece cutting die in the lower edge of fixed block; The top of described fixed block is provided with sliding shoe, and the inner side of sliding shoe is provided with side blind slot, side groove and side blind slot composition side groove; Side groove inner side at fixed block is provided with chute, is provided with the slide rail matching with chute in the side of sliding shoe; And on fixed block, be provided with a bolt, bolt props up the slide rail of sliding shoe through fixed block upper strata.
Compared with prior art, the utility model respectively arranges a cornerite in the both sides of pole piece cutting die, the inboard of cornerite is provided with side groove, and align with the upper edge of pole piece cutting die in the lower edge of cornerite, in the time of punching press, the two ends of pole piece collector are put in the side groove of two cornerites, how the width of cornerite is identical with the metal portion width of pole piece collector, align with the lower edge of cornerite in the coating portion upper edge of pole piece, restarts stamping knife and carry out the punch forming of pole piece.The utility model perfection has solved the problem that cannot align with pole piece cutting die upper edge in the coating portion upper edge of pole piece collector, has improved widely the accuracy of pole piece punching press, has finally reduced defect rate; Meanwhile, the utility model has improved the production efficiency of pole piece widely, is applicable to industrial mass production.Further, when pole piece collector metal portion's width and cornerite width are when inconsistent, or when the pole piece collector of processing different metal portion width, applicant has also done improvement to cornerite, the utility model is by slip sliding shoe, regulate the width of side groove, mate the metal portion width of different pole piece.
