Abstract
The utility model provides a battery aluminium-plastic film with a doubling sink mark. The battery aluminium-plastic film is provided with two grooves for packaging batteries; a spacing distance is left between two grooves; and the doubling sink mark is arranged in the middle of the spacing distance. In the battery aluminium-plastic film, the doubling sink mark is arranged in the middle between the two grooves of the battery aluminium-plastic film, middle folding can be carried out accurately according to the doubling sink mark, and the two grooves can not generate the dislocation phenomenon, so that the production efficiency and the qualification rate of products are improved, the processing procedure is very simple, and the practicability is stronger.
Description
Technical field
The utility model relates to battery and makes field, a kind of specifically battery aluminum plastic film with doubling indenture.
Background technology
Plastic-aluminum packaging film generally is applied to columniform polymer Li-ion battery, and along with the increase of battery capacity, the diameter of battery is also increasing.Therefore, also more and more stricter for the requirement of aluminum plastic film moulding, in the process of aluminum plastic film moulding, must draw back certain distance ability moulding between the groove of two packaged batteries, still, this kind technological requirement has caused very big puzzlement to follow-up manufacturing procedure.See also Fig. 1, be the structural representation of battery aluminum plastic film of the prior art.The groove 20 of two packaged batteries on the aluminum plastic film 10 segment distance of being separated by, following process operation need two grooves 20 are carried out doubling, and in the doubling process, two grooves 20 are easy to dislocation, and cause aluminum plastic film 10 encapsulation wrinkling, occur that gas rises, the phenomenon of leakage.
The utility model content
At above the deficiencies in the prior art and defective, the purpose of this utility model is to provide a kind of battery aluminum plastic film with doubling indenture.
The purpose of this utility model is achieved by the following technical solution:
A kind of battery aluminum plastic film with doubling indenture, this battery aluminum plastic film is provided with the groove of two packaged batteries, and two grooves have a spacing distance, and the middle part of described spacing distance is provided with the doubling indenture.
As optimal technical scheme of the present utility model, the cross section of described doubling indenture is triangular in shape.
As optimal technical scheme of the present utility model, the quantity of described doubling indenture is one.
Compared with prior art, the utility model is provided with a doubling indenture in the middle part of two grooves of battery aluminum plastic film, doubling in can dividing accurately according to this doubling indenture, two grooves inconsistent phenomenon can not occur, improved the qualification rate of production efficiency and product, and manufacturing procedure is very simple, has stronger practicality.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the structural representation of battery aluminum plastic film of the prior art.
Fig. 2 is the structural representation that the utlity model has the battery aluminum plastic film of doubling indenture.
Fig. 3 is the enlarged diagram of a-quadrant among Fig. 2.
Embodiment
See also 2 and Fig. 3, be respectively the enlarged diagram of a-quadrant among the structural representation of the battery aluminum plastic film that the utlity model has the doubling indenture and Fig. 2.This battery aluminum plastic film 101 with doubling indenture is provided with the groove 102 of two packaged batteries, this two groove 102 has a spacing distance, doubling indenture 103 is positioned at the middle part of this spacing distance, and the cross section of this doubling indenture 103 is triangular in shape, and its quantity is one.
This battery aluminum plastic film 101 with doubling indenture is in the doubling process, doubling in can dividing accurately according to doubling indenture 103, two grooves 102 inconsistent phenomenon can not occur, have improved the qualification rate of production efficiency and product, and manufacturing procedure is very simple, has stronger practicality.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
