Embodiment
Combine accompanying drawing that the present invention is done further explain through embodiment below.
Please refer to Fig. 1, the electric core apparatus for baking of the flexible-packed battery of this execution mode comprises baking machine, electric core anchor clamps 10 and forcing press 20; Wherein, Baking machine is used for the electric core of accomplishing preliminary filling is toasted, thereby discharges the inner unnecessary gas that produces in the preliminary filling process, and electric core anchor clamps 10 are used for the electric core that one or more is to be baked and clamp; Make pole piece in the electric core receive certain restraining force and be difficult in bake process, deforming, forcing press 20 is used to electric core anchor clamps 10 clamping force is provided.
Particularly, electric core anchor clamps 10 comprise top board 11, base plate 12, pressing plate 13, at least one locking member 17 and at least one guide part 14.
Top board 11 all is positioned at base plate 1 top with pressing plate 13, and the gap that is formed for placing electric core between pressing plate 13 and the base plate 12.Guide part 14 can be parts such as guide pillar, guide rail, and bearing of trend and top board 11, base plate 12 are vertical with pressing plate 13.The bottom of guide part 14 is fixed on the base plate 12, and the top is fixedly connected with top board 11, and pressing plate 13 forms moving sets with guide part 14 and can move up and down along guide part 14, thus away from or near base plate 12.Pressing plate 13 can compress the electric core that is placed between pressing plate 13 and the base plate 12 during near base plate 12.When guide part 14 is guide pillar, also be provided with on the pressing plate 13 and be used for the through hole that guide pillar passes, preferably, guide part 14 has four, and lays respectively at four bights of electric core anchor clamps, so that pressing plate 13 moves up and down along guide part 14 reposefully.
Locking member 17 matches with top board 11, and preferred locking member 17 can adopt lock-screw, and quantity is decided according to concrete needs.When pressing plate 13 is pressed on electric core between pressing plate 13 and the base plate 12; Locking member 17 passes the screw on the top board 11 and is mated; Thereby utilize its end only to prop up the upper surface of pressing plate 13, thereby lock the distance between pressing plate 13 and the base plate 12, avoid electric core loosening.For simplified structure and keep the dynamics balance, preferably screw is arranged on the central authorities of top board 11, and adopts a lock-screw to prop up the middle part of pressing plate 13 downwards.Forcing press 20 can be the forcing press 20 that hydraulic pressure or air pressure drive, and comprises at least one pressure head 21, and this pressure head 21 may extend to pressing plate 13 tops, and pushes pressing plate 13 downwards it is moved and progressively near base plate 12 along guide part 14.Preferably, forcing press 20 has two pressure heads 21, is respectively applied for the both sides of pushing pressing plate 12, can make pressing plate 13 even stressed and uniform motion, avoids unbalance stress and the crushing pole piece.
Difference according to electric core size specification; Can toast one or more electric core during each the baking; When toasting a plurality of electric core simultaneously, electric core anchor clamps 10 also comprise at least one dividing plate 16, and these dividing plates 16 are arranged between pressing plate 13 and the base plate 12 and stacked distribution; The gap that is used to place electric core between pressing plate 13 and the base plate 12 is divided into multilayer, all can places one or more electric core on each dividing plate 16.These dividing plates 16 also form moving sets with guide part 14, and when under the pushing effect of pressing plate 13 at forcing press 20 during progressively near base plate 12, these dividing plates 16 are also received the motive force of pressing plate 13 and from top to bottom successively progressively near base plate 12, up to all electric cores are compressed.
Parts such as the top board 11 of this execution mode, base plate 12, pressing plate 13, guide part 14 and dividing plate 16 all adopt resistant to elevated temperatures metal to make; Yet; Clamp in the process of electric core, because metal lacks flexibility, forcing press 20 maybe be owing to being difficult to the control dynamics or the excessive pole piece that breaks of exerting oneself in compressing the process of electric core; For fear of this situation, electric core anchor clamps 10 can comprise that also at least one is used to fill up the super gasket 15 of front, reverse side or the positive and negative put at electric core.These super gaskets 15 have certain elasticity, can be to stressed the play cushioning effect of electric core in compaction process, thus effectively protect pole piece.The material of super gasket 15 can adopt to have and siloxane compound or silastic material, and size can be slightly less than the area of dividing plate 16 or base plate 12, so that be applicable to the electric core of all size.Each place electric core before, can be at first on base plate 12 and each dividing plate 16, place a super gasket 15, be placed on electric core on the super gasket 15 after, above each electric core, place a super gasket 15 more again, begin to utilize forcing press 20 to clamp electric core again.
As shown in Figure 2, the electric core baking method of a kind of flexible-packed battery of present embodiment may further comprise the steps:
Step S201: the electric core of the flexible-packed battery behind the preliminary filling is placed between the base plate 12 and pressing plate 13 of baking anchor clamps; When toasting a plurality of electric core simultaneously; Also have a plurality of dividing plates 16 between base plate 12 and the pressing plate 13, therefore can a plurality of electric cores be placed on the different dividing plate 16.
Step S202: electric core just and/or reverse side be encased inside super gasket 15 so that protect electric core.Certainly also can before step S201, at first on base plate 12 and each dividing plate 16, place a super gasket 15.
Step S203: utilize the pressure head 21 of forcing press 20 to push pressing plate 13 downwards, make it move and electric core is clamped between pressing plate 13 and the base plate 12 along the guide part 14 that is fixed on the base plate 12.
Step S204: utilize the distance between locking member 17 locking pressing plates 13 and the base plate 12 to avoid electric core to unclamp; Soon lock-screw passes the screw on the top board 11 from top to down and screws; Make the bottom of its lock-screw tightly prop up the upper surface of pressing plate 13, remove the pressure head 21 of forcing press 20 then.
Step S205: will toast anchor clamps 10 and insert in the baking machine together with electric core and toast.
Step S206: baking finishes, and will toast the electric core of anchor clamps 10 connections and take out baking machine together, subsequent handling such as then seals.
Flexible-packed battery of the present invention can be the flexible packing lithium ion battery of plastic-aluminum shell or the flexible-packed battery of other types.When the electric core after utilizing electric core anchor clamps of the present invention and electric core apparatus for baking to preliminary filling toasts; Because electric core itself receives external force constraint; Can effectively avoid electric core in receiving thermal process, to deform and pole piece generation fold; Therefore significantly improved the evenness of electric core, made it keep good surface appearance and performance.
Above content is to combine concrete execution mode to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
