Description

A kind of lamination flexible package lithium cell
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.
