Abstract
A method for processing Li cell Al cover is to punch several raws regular arranged through holes on a panel Al plate then to punch a slightly sunk stepped surface at every through hole of the Al plate possitive to put the Al plate into an injectino machine after cleaning to inject an insulation plate at each through hole once to put in a rivet on each insulation plate and an electrode plate under it after taking out the Al plate to be riveted to do the surface process, each through hole corresponds to the finished product Al cover, which can process several raws Al covers at the same time.
Description
Technical field: the present invention relates to a kind of method of making the Aluminum cover of lithium battery.
Background technology: the Aluminum cover of lithium battery is used to be welded on the top of battery container, and the electrode slice on the Aluminum cover then needs to separate by insulating trip with Aluminum cover itself and just can constitute electrode and use.When making Aluminum cover now, generally all direct blanking punched after the aluminium flake punching is the semi-finished product of small pieces, and insulating trip then is after making well in addition, respectively adorns on the semi-finished product positive and negative of small pieces by hand and takes a slice insulating trip, going up rivet and electrode slice then, is finished product with the blocks of riveted of semi-finished product again.The mode efficient that this dress is piecewise taken production is low, makes cost very high, because the size of Aluminum cover is less, manual dress is taken the insulating trip inconvenience, and positioning accuracy is lower, influences rate of finished products.And the insulating trip on the Aluminum cover adopts positive and negative that the separate form of a slice is respectively arranged, and the insulated enclosure performance reliability is reduced, and may influence the functional reliability of lithium battery.
Summary of the invention: the present invention is that to solve the efficient of producing Aluminum cover now low, and the problem that cost is high provides a kind of and produces efficiently, the manufacture method of lithium battery Aluminum cover easily.
Manufacturing step of the present invention is followed successively by:
(a) be ready to the satisfactory tabular aluminium flake of dimensions, go out the regularly arranged through hole of plurality of rows on aluminium flake, the number of permutations of through hole is determined according to the size specification of aluminium flake and the Aluminum cover specification quantitative requirement of final finished;
(b) all stamp out the step surface of depression slightly in each through hole in aluminium flake front, to the punching press correction once more of each through hole, clean aluminium flake more then;
(c) aluminium flake is put into injection molding machine, insulating trip in the injection moulding in each through hole after the taking-up aluminium flake removes injection molding channel and tailing;
(d) in each through hole of aluminium flake, promptly each insulating trip above put into rivet, then put a slice electrode slice below, then each rivet of riveted and electrode slice;
(e) aluminium flake is blanking punched, the Aluminum cover of the corresponding final finished of each through hole;
(f) Aluminum cover that punching press is dropped out cleans the surface treatment of light, obtains qualified final finished.
Be unit with the aluminium flake during injection moulding of the present invention, can disposable insulating trip in all through hole injection mouldings on the aluminium flake be need not to adorn piecewise to take that production efficiency is very high, and the injection moulding positioning accuracy is better, material use is abundant, and insulating trip is an integral type, and insulated enclosure is good.
Other production stage of the present invention, as riveted process etc. all is to be unit with the aluminium flake, also be that the plurality of rows Aluminum cover is operated manufacturing simultaneously, production efficiency significantly improves, and cost can significantly reduce, and the properties of product of production are reliable, in actual production, if the employing dedicated manufacturing equipment, the size of aluminium flake can be quite big, and efficient is more increased like this.
Further specify the present invention below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the front view of aluminium flake;
Fig. 2 is the front view of Aluminum cover;
Fig. 3 is the A-A cutaway view of Fig. 2.
Embodiment: when making, the present invention produces as follows successively,
(a) go out the regularly arranged through hole of plurality of rows 2 on tabular aluminium flake 1, the number of permutations of through hole 2 is determined according to the size specification of aluminium flake 1 and the Aluminum cover 6 specification quantitative requirements of final finished, general through hole 2 more than a slice aluminium flake 1 upper punch four rows;
(b) all stamp out the step surface of depression slightly at each through hole 2 place in aluminium flake 1 front, to each through hole 2 punching press correction once more, clean aluminium flake 1 more then;
(c) aluminium flake 1 is put into injection molding machine, insulating trip 3 in each injection moulding in through hole 2 places after the taking-up aluminium flake 1 removes injection molding channel and tailing, generally also recyclable utilization again;
(d) at each through hole 2 place of aluminium flake 1, promptly each insulating trip 3 above put into rivet 4, then put a slice electrode slice 5 below, then each rivet 4 of riveted and electrode slice 5;
(e) aluminium flake 1 is carried out blanking punched, the Aluminum cover 6 of each through hole 2 corresponding final finished;
(f) Aluminum cover 6 that punching press is dropped out cleans the surface treatment of light, obtains qualified final finished.
During manufacturing, each through hole 2 on the aluminium flake 1 is used to wear rivet 4, electrode slice 5 and aluminium flake 1 behind the riveted, i.e. and the electrode that Aluminum cover 6 insulation of final finished separate as lithium battery uses.Insulating trip 3 on the Aluminum cover 6 that the present invention produces is an integral type, and the step surface at each through hole 2 place then makes the insulating trip 3 of injection moulding in conjunction with reliable, and insulating trip 3 is extruded distortion after preventing riveted.In the reality, except that stamping out the step surface in aluminium flake 1 front, can also also stamp out the step surface of depression slightly as required at each through hole 2 place of aluminium flake 1 reverse side, the combination of insulating trip 3 and Aluminum cover 6 is more reliable like this, and insulated enclosure is better.
The manufacture of lithium battery has multiple, many lithium batteries are annotated electrolyte after all being welded on Aluminum cover on the battery container again, can before blanking, in aluminium flake 1, go out earlier plurality of rows and through hole 2 liquid injection hole 7 one to one when producing like this, promptly have liquid injection hole 7 on the Aluminum cover 6 behind the blanking.
