Description

A kind of cutting tool of polymer Li-ion battery
Technical field
The utility model relates to the battery technology field, particularly relates to a kind of cutting tool of polymer Li-ion battery.
Background technology
At present, lithium ion battery have specific energy high, recycle often, the advantage such as memory time is long, not only on portable electric appts, be used widely such as mobile phone, DV and laptop computer, and be widely used in the big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool.
Wherein, for the polymer soft bag lithium ionic cell, it is as a kind of novel lithium ion battery, have the advantages such as voltage is high, specific energy is high, good cycle, compare traditional lithium-ion battery with steel shell, polymer soft bag lithium ionic cell outward appearance is more flexible, uses more extensive in the various digital products such as notebook, mobile phone, digital camera, bluetooth earphone, portable media player.
At present, polymer Li-ion battery adopts a kind of special aluminum-plastic packaging film to substitute original steel casing as the encapsulating material of battery.Polymer Li-ion battery for guaranteeing packaging effect, uses higher temperature and pressure in the process of top encapsulation.Because the lug position is different from the suffered lateral pull of the housing of battery both sides, under HTHP, the deformation quantity of housing is different, cause battery container both sides shell length will be longer than the lug position, and the battery pole ear design itself has surplus to exist, for satisfying the dimensional requirement of digital product, need to cut unnecessary housing and lug.
Current, in order to cut unnecessary housing, be generally the battery production employee and use the scissors manual pruning, size, precision can't guarantee, the uniformity of product is poor, production efficiency is low, and scissors is more sharp, the employee is in operating process, and the risk that battery container is scratched, scratches is higher.In addition, in order to cut unnecessary battery pole ear, by adopting horizontal linear type cutter, after process cut, the drift angle of battery pole ear was more sharp-pointed, easily causes battery container to stab.
The utility model content
In view of this, the purpose of this utility model provides a kind of cutting tool of polymer Li-ion battery, it can make things convenient for, efficiently battery pole ear and the battery container of redundance be cut, improve and cut operating efficiency, guarantee the uniformity of the lithium ion battery of producing, be conducive to reduce the production cost of polymer Li-ion battery, improve the market competitiveness of polymer Li-ion battery, be of great practical significance.
For this reason, the utility model provides a kind of cutting tool of polymer Li-ion battery, comprises two battery pole ear cutting tools, has the recessed edge of a knife of arc on the described battery pole ear cutting tool.
Wherein, the left end of described battery pole ear cutting tool or right-hand member have the described edge of a knife.
Wherein, the described edge of a knife is the U-shaped edge of a knife.
Wherein, also comprise two housing cutting tools.
Wherein, described housing cutting tool is the linear pattern cutter that transverse horizontal distributes, and left end or the right-hand member of described housing cutting tool have blade.
The technical scheme that is provided by above the utility model as seen, compared with prior art, the utility model provides a kind of cutting tool of polymer Li-ion battery, it can make things convenient for, efficiently battery pole ear and the battery container of redundance be cut, raising cuts operating efficiency, guarantees the uniformity of the lithium ion battery of producing, and is conducive to reduce the production cost of polymer Li-ion battery, improve the market competitiveness of polymer Li-ion battery, be of great practical significance.
