Abstract
The utility model discloses an aluminum-plastic film packaging structure for an outer package of a polymer battery, which can prevent the phenomenon that the bottom corners are cracked because an air bag is bent in the production process. The aluminum-plastic film packaging structure comprises an aluminum-plastic film air bag, wherein a pole group is positioned in the aluminum-plastic film air bag; and the lateral side of the pole group is provided with an air bag packaging region. The aluminum-plastic film packaging structure is characterized in that: a notch is formed in the air bag packaging region of an aluminum-plastic film. Due to the adoption of the aluminum-plastic film packaging structure for the outer package of the polymer battery, the root of the battery cannot be bent even if the air bag is repeatedly bent, so that the phenomenon that the bottom corners are cracked is prevented. The aluminum-plastic film packaging structure for the outer package of the polymer battery is simple and practical and is convenient to operate. The defective rate of products can be greatly reduced by slightly changing the structure, the cost is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of lithium ion battery production process equipment, and the aluminum plastic film encapsulating structure is used in especially a kind of polymer battery external packing.
Background technology
Polymer Li-ion battery is a kind of as lithium ion battery, has the advantages that volume is little, in light weight, performance is high, safe and reliable, and application is extremely extensive, comprises mobile phone, bluetooth earphone, MP3, DVD, notebook computer etc., and the market development prospect is unlimited.
What the polymer battery external packing was used is aluminum plastic film.As shown in Figure 1, for being put into wherein, utmost point group encapsulates, need aluminum plastic film 1 is carried out punching press, go out a concave surface 2, the edge 3 of concave surface 2 is in situation about being stretched like this, this position aluminum plastic film strength reduction.Like Fig. 2, shown in 3, the polymer battery external packing with the aluminum plastic film encapsulating structure in, utmost point group is positioned at the airbag 4 of aluminum plastic film, 3 places encapsulate it on the edge of.Produce and circular flow in can a take side of airbag 4 because plastic-aluminum is membranous soft, can be folded into battery bottom, i.e. 3 positions, edge, the bad phenomenon that after repeatedly bending, just can cause the base angle to be split.
The utility model content
The technical problem that the utility model will solve provides and a kind ofly can overcome in the production process because the aluminum plastic film encapsulating structure is used in the polymer battery external packing of the situation that the base angle that the bending airbag causes is split.
For addressing the above problem; The aluminum plastic film encapsulating structure is used in a kind of polymer battery external packing of the utility model, comprises the aluminum plastic film airbag, and utmost point group is positioned at the aluminum plastic film airbag; The side edge of utmost point group is the airbag encapsulation region, it is characterized in that: said aluminum plastic film offers otch in the airbag encapsulation region.
Said otch is positioned at the centre position of airbag encapsulation region.
Adopt the polymer battery external packing of the utility model structure to use the aluminum plastic film encapsulating structure,, also can not fold to the battery root position, thereby stopped the appearance that phenomenon is split at the base angle even repeatedly bend airbag.The aluminum plastic film encapsulating structure is used in the polymer battery external packing of the utility model, and is simple and practical, easy to operate, just can greatly reduce the defect rate of product with minimum structural change, practiced thrift cost, improved productivity effect.

Embodiment
In order to make those skilled in the art person understand the utility model technical scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and execution mode.
Like Fig. 4, shown in 5; The aluminum plastic film encapsulating structure is used in the polymer battery external packing of the utility model, comprises aluminum plastic film airbag 4, and utmost point group is positioned at aluminum plastic film airbag 4; The side edge of utmost point group is an airbag encapsulation region 5, and said aluminum plastic film offers otch 6 in airbag encapsulation region 5.
Said otch 6 is positioned at the centre position of airbag encapsulation region 5.
Adopt the polymer battery external packing of the utility model structure to use the aluminum plastic film encapsulating structure,, also can not fold to the battery root position, thereby stopped the appearance that phenomenon is split at the base angle even repeatedly bend airbag.The aluminum plastic film encapsulating structure is used in the polymer battery external packing of the utility model, and is simple and practical, easy to operate, just can greatly reduce the defect rate of product with minimum structural change, practiced thrift cost, improved productivity effect.
