The main edge contraction area 15 in two tops is respectively distributed to one of two major opposing side areas of coverage 12 away from bottom footprint 11
Side, and separated by the 6th folding line section 10c1 with the major opposing side area of coverage 12, the narrow edge contraction area 16 in four tops is respectively distributed to four
The individual narrow side area of coverage 13 passes through the 7th folding line section 10c2 and narrow 13 points of the side area of coverage away from the side for cutting folding region 14
Every the main edge contraction area 15 in adjacent top is then separated with the narrow edge contraction area 16 in top by the 5th folding line section 10b3.
In the present embodiment, dielectric film 1 can along the first crease line 10a, the second crease line 10b, the 3rd crease line 10c with
And first oblique crease line 142 folded, so as to wrap up battery core.
The process of the parcel battery core of the dielectric film 1 in above-mentioned two embodiment is described in detail below.
As shown in figure 3, the battery core 2 in the present embodiment is consistent with common core strueture, with bottom surface 20, major opposing side 21,
Narrow side 22 and top surface 23.Meanwhile, bottom footprint 11 and bottom surface 20, the major opposing side area of coverage 12 and master on dielectric film 1
Face 21 is basically identical or slightly larger.
Parcel when, the first step is that the bottom surface of battery core 2 is placed on the bottom footprint 11 of dielectric film 1, afterwards along point
Every the major opposing side area of coverage 12 Yu bottom footprint 11 the first crease line 10a by the major opposing side area of coverage 12 and the narrow side area of coverage
13 are folded up, and first folding line section 10a1 of the major opposing side area of coverage 12 along the first crease line 10a can cover battery core after turning up
Major opposing side 21, now the narrow side area of coverage 13 also along the second folding line section 10a2 be folded up so that the global sections of dielectric film 1
Take the shape of the letter U.For the dielectric film 1 in second embodiment, the now main edge contraction area 15 in top and the narrow edge contraction area 16 in top
Height will exceed top surface 23 (referring to Fig. 4).
Generally, size of the narrow edge contraction area 16 in the main edge contraction area 15 in top and top along Y-direction is 3~5mm,
Size after folding beyond top surface 23 is more suitable.
Second step is respectively to fold the four narrow side area of coverage 13 along the second crease line 10b towards narrow side 22, and
Wrap up narrow side 22.For the dielectric film 1 in second embodiment, the main edge contraction area 15 in top and top are narrow in the process
Edge contraction area 16 can also be folded along the second crease line 10b the 5th folding line section 10b3, and with the major opposing side each connected
The area of coverage 12 or the narrow side area of coverage 13 are moved to the corresponding side of top surface 23 of battery core 2.
Due to being that the two narrow side area of coverage 13 wraps up one narrow side 22, therefore the narrow side area of coverage 13 is in narrow side 22
The size of width (i.e. the thickness direction of battery core 2) need not be consistent with narrow side 22, it is only necessary to ensure that two narrow sides are covered
Cover region 13 can collectively cover narrow side 22.In this case, the narrow side area of coverage 13 and cut folding region 14 on
Size in X direction may be in the range of 1/2~1 with ratio of the bottom fold area along Y-direction size.According to ratio not
Together, change occurs in the alternate covering scope of the two narrow side area of coverage 13.
When being folded to each narrow side area of coverage 13, due to the presence of otch 140, in cutting folding region 14
And it is possible to the second folding line section along the first crease line 10a with the folded portion 144 that the narrow side area of coverage 13 is connected
The oblique crease lines 142 of 10a2 and first are synchronous to be folded, and this is partially covered on cutting folding region 14 and is located at two otch
(referring to Fig. 5) on region 146 between 140 and two the first oblique crease lines.
After the folding of whole four narrow side areas of coverage 13 is completed, cut in folding region 14 in addition to region 146,
Other parts have been folded on the region 146 (referring to Fig. 6).
As depicted in figs. 1 and 2, distance of the otch 140 away from the first adjacent crease line 10a to folded portion 144 in Y
Size on direction, the i.e. width of folded portion 144 can produce influence, generally, and otch 140 is away from adjacent first
Crease line 10a distance is maintained in the range of 1~10mm, in order to fold.
Meanwhile, the spacing between two otch 140 in same cutting folding region 14 can influence area 146 and cutting
Folding region 14 and ratio, that is, the folded portion 144 folded with the narrow side area of coverage 13 relative size.According to not
Spacing between same technique, two otch 140 can be in 1/3~1 model with the ratio of the cutting folding region 14 along the size of Y-direction
It is adjusted in enclosing.In most preferred scheme, distance of the otch 140 away from the first adjacent crease line 10a and the otch
140 distances away from bottom footprint 11 are equal, now the first oblique crease line 142 will simultaneously with the first crease line 10a and the
Two crease line 10b are in 45 ° of angles, that is, the position in angular bisector.
Certainly, in order that the package structure of the two narrow side 22 of battery core 2 is consistent, the otch in two cutting folding regions 14
140 is preferably symmetrical relative to X-direction and Y-direction.
3rd step is to cut threeth folding line section 10b1 of the folding region 14 along the second crease line 10b by two to be folded up, and is made
It draws the outside for overlaying the narrow side area of coverage 13 in, forms structure shown in Fig. 7.For the dielectric film 1 in one embodiment,
So far just complete to fold, form final use state, but for the dielectric film 1 in second embodiment, will also carry out following
Step：
4th step is that the 6th folding line section 10c1 by the main edge contraction area 15 in top along the 3rd crease line 10c is bent downwards,
The 7th folding line section 10c2 by the narrow edge contraction area 16 in top along the 3rd crease line 10c is bent downwards simultaneously, so as to cover top surface
23 periphery (referring to Fig. 8).
In encapsulation process, in order to prevent interference, can by the main edge contraction area 15 in top and the narrow edge contraction area 16 in top it
Between the 5th folding line section 10b3 severings so that the main edge contraction area 15 in top and the narrow edge contraction area 16 in top are separate, mutually not
Influence.But the program can increase processing step.
More preferred scheme is set between the adjacent narrow edge contraction area 16 in the main edge contraction area 15 in top and top
Second oblique crease line 150, the second oblique crease line 150 extends to dielectric film 1 along X side by the summit for closing on bottom footprint 11
To the side of extension, dielectric film 1 can fold (referring to Fig. 7) along the second oblique crease line 150, so as to avoid the main side folding in top
It is folded to interfere between area 15 and the narrow edge contraction area 16 in top.
Under normal circumstances, the size of the main edge contraction area 15 in top in X direction can be much larger than the narrow edge contraction area 16 in top along X
The size in direction, therefore the narrow edge contraction area 16 in top should not carry out the folding of too many number of times.In this case, the second oblique folding
Trace line 150 is preferably located in the main edge contraction area 15 in top.So far the folding encapsulation process of dielectric film 1 is completed, use state is formed
(referring to Fig. 2).
It should be noted that the first crease line 10a, the second crease line 10b, the 3rd crease line among the embodiment of the present application
10c, the first oblique crease line 150 of oblique crease line 142 and second can the just delineations in advance before barrier film is folded
It is good, the entity state such as forming tag line or weak area, however, it is also possible to not carried out before folding to barrier film any
The processing of form, and respective folded is carried out according to imaginary crease line only in folding process, and ultimately form the use state.
Top paster 3 is sticked at the top of battery core 2 afterwards, whole insulation package structures of battery core 2 are completed (referring to Fig. 3).
The dielectric film 1 that the embodiment of the present application is provided is in bottom when under use state and only includes one layer of bottom footprint
11, therefore not only thickness is relatively low, while also more smooth.
The preferred embodiment of the application is the foregoing is only, the application is not limited to, for the skill of this area
For art personnel, the application can have various modifications and variations, any modification, equivalent substitution and improvements made based on the application
Deng should be included within the protection domain of the application.
