Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings.
Seeing Fig. 1 to Fig. 4, a kind of lug protection zone blanking method encapsulating battery of the present invention, this blanking method comprises the steps:
S1., the aluminum plastic film stamping out base wells 11 and capping pit 12 carries out local cut, can be covered on above base wells 11 after making capping pit 12 bending；
S2. put in battery core mould 16 to base wells 11；
S3. forward upset capping pit 12, makes capping pit 12 be covered on above base wells 11；
S4. the front end at capping pit 12 and base wells 11 is punched out lug protection zone 13
S5. reverse flip capping pit 12, opens base wells 11；
S6. from base wells 11, take out battery core mould 16.
When described aluminum plastic film is after punching mechanism stamps out base wells 11 and capping pit 12; put in battery core mould 16 to base wells 11; it is emphasized that at this: owing to the effect of battery core mould 16 is only intended to support base wells 11 and capping pit 12; so; battery core mould 16 as herein described is not provided with positive and negative lug; meanwhile, to facilitate the follow-up stamping-out carrying out lug protection zone 13；Then capping pit 12 is covered on base wells 11, in general, in the step of S3, forward upset capping pit 12, making capping pit 12 be covered on base wells 11, the capping pit 12 of this step can align one by one with base wells 11, consequently facilitating in subsequent packaging procedures, align, negative electrode lug seals, it is to avoid the head of positive and negative lug is exposed to outside；Then; the base wells 11 putting into battery core mould 16 continues to move along; when moving to blanking mechanism; stamping-out lug protection zone, leading section 13 to capping pit 12 and base wells 11; due under the supporting role of battery core mould 16; the inside of base wells 11 and capping pit 12 is filled; so that in blanking process; base wells 11 and capping pit 12 will not deform; finally, battery core mould 16 is taken out, additionally; battery core 14 as herein described, in addition to having special instruction, each means the true battery core of one of required assembly as battery assembling molding.
Between the step of S1 and S2, also include bending step: between the base wells 11 and capping pit 12 of aluminum plastic film, carry out bending；The purpose of this bending step is: one, follow-up cut lug protection zone 13 time, can quickly capping pit 12 be covered in base wells 11, save flip-flop transition；Two, after capping pit 12 is sold off, it is also possible to be substantially reduced the width of streamline, space is saved.
After automatic stamping molding, need that strip carries out local to cut to form turnover capping pit 12 and base wells 11, owing to have employed the mode that directly cuts, meanwhile, in follow-up Forging Process, the strip not cutting part is easily caused extension tear under the effect of bending power or tilting force or destroys by the cutting line after cutting, cause defective products, in order to reduce the generation of defective products, before S1 step, on aluminum plastic film, stamping-out stops cut hole 15；The effect of described only cut hole 15 is: when entering bending step or S3 step, cut hole 15 till the terminating point that cutting tool cuts, so, during follow-up cutting, only cut hole 15 can be good at avoiding cutting line, by the effect of external force, strip formation is extended tear or destruction, thus improves yields.
In S1 step, described local cuts and refers to cut two sides 17 of capping pit 12；So that capping pit 12 can overturn bending and cover with base wells 11.
In order to improve manufacture efficiency further, in S2 step, described battery core mould 16 is put in base wells 11 by mechanical hand；
Meanwhile, in S6 step, described battery core mould 16 takes out battery core mould 16 by mechanical hand from base wells 11.In order to realize putting into battery core mould 16 to base wells 11 before stamping-out lug protection zone 13 simultaneously, and after stamping-out lug protection zone 13, battery core mould 16 is taken out from base wells 11, this manufacture method employs draw off gear 2, this draw off gear 2 includes mechanism rack 21, it is provided with synchronous motor 22 in mechanism rack 21 and synchronizes wheel 23, synchronous motor 22 is by Timing Belt 24 and the connection of Tong Bu wheel 23, Timing Belt 24 is provided with the first mechanical hand 25 and the second mechanical hand 26, battery core mould 16 was put in molding before stamping-out lug protection zone 13 by described first mechanical hand 25, then, Timing Belt 24 drives the first mechanical hand 25 to move right, battery core mould 16 after completing stamping-out lug protection zone 13 takes out；It is to be noted that while battery core mould 16 put into by above-mentioned first mechanical hand 25, battery core mould 16 is taken out by the second mechanical hand 26 immediately, while first mechanical hand 25 moves right, Timing Belt 24 also drives the second mechanical hand 26 to be moved to the left, the battery core mould 16 of taking-up is moved to the left side, while the first mechanical hand 25 takes out battery core mould 16, second mechanical hand 26 is put in battery core mould 16 to contoured pocket, interactive gearing picks and places, from above-mentioned, prior art needs the work that two mechanical hands are respectively completed, the work that is placed and taken out can be solved by this draw off gear 2 simultaneously, compared with prior art, this draw off gear 2 has simple in construction, the advantage that folding and unfolding efficiency is high and cost-effective.
In S3 step, described forward upset capping pit 12 refers to utilize switching mechanism that capping pit 12 forward is overturn 90 ~ 120 degree；In S5 step, described reverse flip capping pit 12 refers to utilize switching mechanism by capping pit 12 reverse flip 90 ~ 120 degree, the angle of the upset of above-mentioned forward or reverse flip is according in bending step, the bending angle of capping pit 12 is adapted, when the bending angle of capping pit 12 is 90 degree, the angle of the upset of its forward or reverse flip is 90 degree, the horizontal space minimum that whole strip is shared when moving, but its longitudinal space takies at most, easily affect the space of mechanical hand；When the bending angle of capping pit 12 is 120 degree, the angle of the upset of its forward or reverse flip is 120 degree, although less to the longitudinal space taking mechanical hand, but horizontal space shared when whole strip moves is maximum；In the present embodiment, it it is 100 degree as preferred angle, i.e., in bending step, the bending angle to capping pit 12 is 100 degree, now, when strip moves, horizontal space is moderate, its capping pit 12 tilted, the longitudinal space also taken is the most relatively mild, and beneficially robot movement picks and places battery core mould 16.
When battery core mould 16 is put in base wells 11 by mechanical hand; between the step of S2 and S3; also include rolling step; after base wells 11 put into by battery core mould 16, rolling wheel is set and battery core mould 16 is depressed into the inside bottom surface of base wells 11, under the effect of rolling wheel; battery core mould 16 is pressed into base wells 11 further; make base wells 11 be filled up completely with, it is to avoid leaving space, thus protect support effect.
Above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the thought of the present invention, the most all will change, and this specification content should not be construed as limitation of the present invention.
