Description
Technical field
This utility model belongs to a kind of lamination flexible packing lithium ion battery method for packing field, is more particularly to a kind of lamination
Flexible package lithium cell.
Background technology
Laminating machine " Z " font lamination techniques, last barrier film cut off, respectively reserve in the both sides of battery core a segment distance unnecessary every
Film;During rubberizing, barrier film loses money instead of making money volt to battery core edge surface folding, and length can exceed that battery core another side, general rubberizing 3 are translated in side
Road;During encapsulation, what battery core was placed in aluminum plastic film rushes in hole, is packaged, and through closedtop, side seal, two envelope processes, forms the electricity sealed
Pond entity.
When laminating machine barrier film cuts off, due to the restriction of machine construction, barrier film cannot realize cut-out concordant with battery core, or two
The distance grown is reduced on limit simultaneously;During rubberizing, adhesive tape pastes 3 roads, but will not align patch with two ends;During encapsulation, battery two ends
Barrier film is easy to turn up, or barrier film is sucked out when two envelopes, causes edge sealing bad, the most directly leaks gas.
Utility model content
1, the purpose of this utility model.
The problem that this utility model is bad in order to improve barrier film edge sealing during lithium battery encapsulation, and propose a kind of lamination
Flexible package lithium cell.
2, the technical scheme that this utility model is used.
The lamination flexible package lithium cell that the utility model proposes, including battery core, barrier film, adhesive tape, aluminum plastic film;Barrier film relative to
The diaphragm length that battery core width both sides have more respectively is different, is divided into barrier film minor face and the long limit of barrier film;Short slab and the long limit of barrier film are suitable
Gesture lodges in the side of battery core, and outer symmetrical Continuous pressing device for stereo-pattern is fixed, by aluminum plastic film outer enclosure.
In order to prevent barrier film from turning up when encapsulating, described barrier film minor face is less than 5mm beyond the length of battery core.
Further improving the packaging effect of barrier film, the long limit of described barrier film exceeds the length thickness more than battery core of battery core
Degree.
Further improving the packaging effect of barrier film, described adhesive tape is four adhesive tapes.
3, the beneficial effects of the utility model.
This utility model, by designing the structure of barrier film and adhesive tape, eliminates the situation that barrier film is enclosed in edge sealing, improves
The qualification rate of product.

Detailed description of the invention
Embodiment 1
The lamination flexible package lithium cell that the utility model proposes, including battery core, barrier film, adhesive tape, aluminum plastic film;Barrier film relative to
The diaphragm length that battery core width both sides have more respectively is different, is divided into barrier film minor face and the long limit of barrier film, and barrier film minor face is beyond battery core
Length is less than 5mm, and the long limit of barrier film exceeds the length thickness more than battery core of battery core;Lodging is taken advantage of a situation at electricity in the minor face of barrier film and long limit
The side of core, outer symmetrical is pasted four adhesive tapes and is fixed, by aluminum plastic film outer enclosure.
Carry out integrated regulation for edge sealing problem, including adjusting the position of laminating machine cutting knife, make what electric core membrane cut off to stay
Limit change, back gauge of staying accomplish less than 5mm;The distance of regulation end socket distance battery core is at 2-3mm;Being located proximate to of rubberizing
The two ends of battery core, quantity increasing is increased to 4;Corresponding two edge sealing in side that barrier film stays limit little are placed;
Including: the battery core that lamination completes cuts off (Fig. 1 and Fig. 2) through barrier film, takes off, then carry out battery core from lamination stacking table
Tape (Fig. 3 and Fig. 4), carries out subsequent operation after fixing for battery core every layer;Through the encapsulation of 2 times (Fig. 5) operation, seal and formed
Battery.
Embodiment 2
Battery core (2) is pulled out by mechanical hand (3) from lamination stacking table (1), and cutting knife (5) cuts off the barrier film (4) involved, and battery core both sides are divided
The diaphragm length that do not has more is different, has dividing of minor face (4-1) and long limit (4-2);
Barrier film is taken advantage of a situation, and folding is the most symmetrical pastes 4 adhesive tapes (6-1,6-4), and outside belt and barrier film have position relationship;Closedtop and
During side seal, battery core is placed in aluminum plastic film (7) by minor face and long limit rule;Side seal end socket (8) and two envelope end sockets (9) have with battery core
Position relationship.
Embodiment 3
The present embodiment is the further optimization to embodiment 2.
Barrier film minor face is less than 5mm;Two ends adhesive tape to barrier film distance less than 5mm;The long limit of barrier film minor face correspondence aluminum plastic film;End socket
The distance on limit is cheated at 2-3mm to aluminum plastic film punching;The hole of punching in advance of aluminum plastic film, cheats deep about 5mm.
The present invention, by simple design, eliminates the situation that barrier film is enclosed in edge sealing, improves the qualification rate of product.
Claims (4)
1. a lamination flexible package lithium cell, it is characterised in that: include battery core (2), barrier film (4), adhesive tape (6), aluminum plastic film (7);
Barrier film is different relative to the diaphragm length that battery core width both sides have more respectively, is divided into barrier film minor face (4-1) and the long limit of barrier film (4-
2);Taking advantage of a situation and lodge in the side of battery core (2) in the short slab of barrier film and long limit, outer symmetrical Continuous pressing device for stereo-pattern (6) is fixed, and passes through aluminum plastic film
(7) outer enclosure.
Lamination flexible package lithium cell the most according to claim 1, it is characterised in that: described barrier film minor face (4-1) exceeds
