Embodiment
Set forth the several different most preferred embodiment of the utility model below with reference to the accompanying drawings, wherein in different figure, identical label represents identical parts.
As shown in figures 2-3, the utility model provides a kind of packaging system 1 of flexible packing lithium ion electric core 3, comprises encapsulation end socket 10 and a blend stop 20.Encapsulation end socket 10 comprises upper cover 12 and a bottom head 14, and upper cover 12 is equipped with mutually engageable tooth 16 with the opposite face of bottom head 14.As shown in the figure, upper cover 12 is roughly T-shaped, and bottom head 14 is roughly in inverted T-shaped, and when upper cover 12 engages with bottom head 14, the shape of cross section of encapsulation end socket 10 is in " work " font.Particularly, bottom head 14 is in inverted T-shaped, namely both sides respectively have a step surface 142, on blend stop 20 step surface 142 located therein, and blend stop 20 is adjustable with the lateral separation of encapsulation end socket 10, flexible packing lithium ion electric core 3 is placed on blend stop 20, adjustment blend stop 20 and the distance encapsulating the distance of end socket 10 and the film airbag mouth 32 distance packaged end socket 10 of adjustable flexible packing lithium ion electric core 3.
Concrete operations are: be placed in by flexible packing lithium ion electric core 3 on blend stop 20, the distance of adjustment blend stop 20 distance packaged end socket 10, the film airbag mouth 32 of flexible packing lithium ion electric core 3 is made to be placed between the tooth 16 of upper cover 12 and bottom head 14, then upper cover 12 and bottom head 14 is closed as shown in Figure 3, can hermetically sealed film airbag mouth 32 under certain pressure, temperature, time effect.Preferably, the distance that film airbag mouth 32 stretches out encapsulation end socket 10 is 0 ~ 0.2mm, and in other words, the distance at positional distance film airbag mouth 32 edge of encapsulation end socket 10 diaphragm seal airbag mouth 32 is 0 ~ 0.2mm.Due to the miscellaneous part of packaging system 1, and pressure, temperature, time that the utility model relates to be prior art, do not repeat them here.
The concrete shape of encapsulation end socket 10 is also not limited to as mentioned above, as shown in Figures 4 and 5, bottom head 14 is substantially L-shaped, and upper cover 12 is roughly in inverted L shape, when upper cover 12 and bottom head 14 engage, the shape of cross section of encapsulation end socket 10 is the rectangle of a side openings.Certainly, the encapsulation end socket 10 of other shapes of energy encapsulating film airbag mouth 32 is also applicable to the utility model.
Upper cover 12 is equipped with mutually engageable tooth 16 with the opposite face of bottom head 14, Fig. 2 ~ 5 illustrate jagged tooth 16, in other embodiments, the tooth 16 of upper cover 12 or bottom head 14 also can in rectangle as shown in Figure 6 or waveform as described in Figure 7, as long as upper cover 12 is engageable with bottom head 14, the tooth of other shapes is also applicable to the utility model.
Because upper cover 12 of the present utility model can engage each other with bottom head 14, therefore dislocation is less likely to occur, the flatness requirement of upper cover 12 and bottom head 14 is also reduced simultaneously, make the fusion adhesive strength of film airbag mouth 32 larger, its adhesive strength average out to 35.0N, the air pressure size produced in subsequent technique such as to change into, cure much larger than flexible packing lithium ion battery, achieve flexible packing lithium ion battery without leakage, without bulging, improve the qualification rate of flexible packing lithium ion battery.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
