Abstract
The utility model provides an exempt from a formula aluminium and change nickel electrode lug, glue and protect and glue including aluminium strip, nickel strap, utmost point ear, it overlaps connecting portion to form through the welding mode between aluminium strip and the nickel strap, is the length of overlapping connecting portion 1 3mm, cladding surface about the aluminium strip is glued to utmost point ear, the protection is glued through hot pressing or is pasted mode cladding surface about overlapping connecting portion, be it 0.1 to overlap the connecting portion lower extreme distance gluey apart from utmost point ear 1mm, is the length that the protection was glued 2 4mm, is the thickness that the protection was glued 30 mu m 80 mu m, is the protection glued one end and is 0.1 to the gluey distance that corresponds the end of utmost point ear 1mm. The utility model discloses direct using after producing, need not fold and to paste this twice bottleneck process of double faced adhesive tape below aluminium utmost point ear aluminium utmost point ear again, the cost of both having used manpower sparingly improves production efficiency again, can reduce effectively that warp or the rupture leads to the direct condemned phenomenon emergence of battery because of utmost point ear, is showing the reduction defective rate.
Description
Technical field
This utility model is related to lithium ion battery production technical field, particularly to a kind of folding-free aluminium-to-nickel lug.
Background technology
Need in polymer Li-ion battery manufacture process to use a kind of aluminium pole ears, to aluminium pole ears exposed junction before PACK
One nickel sheet of switching is beneficial to welding.But due to aluminum soft material itself, lug thickness of thin, and its folding strength is not also high, typically
Repeat to bend and be just easy to that fracture occurs for 5 times about.Automaticity plus lithium ion battery manufacturing process is generally relatively low, handss
Work operation is many, so aluminium strip is easy to bend in process of production, leads to aluminium pole ears deformation and rupture.For bluetooth
The baby batteries such as battery, aluminium pole ears fracture fraction defective up to 5%-10%, the larger battery of volume, aluminium pole ears fracture ratio can
Reach 0.5-1%, lead to finished battery directly to be scrapped, cause cost to raise the wasting of resources.
Traditional aluminium-to-nickel lug reaches client after producing and also needs to aluminium pole ears be folded and in aluminum
This two procedures of double faced adhesive tape are pasted, presently this two procedures is difficult to realize automation mechanized operation, becomes operation bottleneck below lug,
It is typically only possible by substantial amounts of manual operation to solve, thus increased the human cost of client, its low production efficiency.
And the Laser Welding aluminium-to-nickel lug (welding nickel sheet in advance in the exposed junction of aluminium pole ears) developed in recent years can only help
Battery operation reduces aluminium-to-nickel operation, and cannot thoroughly solve the problems, such as aluminium pole ears deformation or rupture, and there is still a need for electricity
Pond carries out rolling over lug and patch double faced adhesive tape operation below lug, and this two operations of battery production make production efficiency low, hold
The phenomenon easily deforming or rupturing.
Utility model content
This utility model is directed to the disappearance of prior art presence, provides a kind of folding-free aluminium-to-nickel lug, it is produced
After can directly using need not again aluminium strip be folded and below aluminium strip paste this two procedures of double faced adhesive tape, both save manpower become
This, improve production efficiency again, and it can prevent lug deformation or fracture, and effectively reduces because of lug deformation or fractures and lead to battery
The phenomenon that cost is directly scrapped occurs, and significantly reduces fraction defective.
For achieving the above object, this utility model is using as purgation technical scheme：
A kind of folding-free aluminium-to-nickel lug, including aluminium strip, nickel strap, tab and Protection glue, between described aluminium strip and nickel strap
Overlapping connecting portion is formed by welding manner, the length of described overlap connecting portion is 1-3mm, and described tab is coated on aluminium strip
Lower surface, described Protection glue is coated on overlapping connecting portion upper and lower surface by hot pressing or bonding method, under described overlap connecting portion
End is 0.1-1mm apart from the distance of tab, and the length of described Protection glue is 2-4mm, and the thickness of described Protection glue is 30 μm -80
μm, the distance of one end to the tab corresponding end of described Protection glue is 0.1-1mm.
As a kind of preferred version, the material of described Protection glue is one of PE, PP, CPP, PET and PVC.
This utility model compared with prior art, has advantages below and advantage, specifically, the aluminium strip of this lug and nickel
Between band, overlapping connecting portion is formed by welding manner, described Protection glue is coated on overlapping connecting portion by hot pressing or bonding way
Upper and lower surface, so can effectively prevent aluminium strip from deformation in battery core manufacture process and the rear course of processing or rupturing, effectively
Reduce because of lug deformation or the phenomenon generation leading to battery cost directly to be scrapped that fractures, significantly reduce fraction defective；On the other hand this
The lug that sample is produced can directly use, and client need not be folded to aluminium strip again and paste this twice of double faced adhesive tape below aluminium strip
Operation, saves substantial amounts of human cost；Due to being folded to aluminium strip and being pasted this two bottleneck operations of double faced adhesive tape below aluminium strip
Can directly save, so the production cycle of battery can shorten 0.5-1 days, improve production efficiency.
For more clearly illustrating architectural feature of the present utility model, technological means and its specific purposes being reached and work(
Can, come with specific embodiment below in conjunction with the accompanying drawings this utility model is described in further detail：
Brief description

Specific embodiment
As shown in Figure 1, 2, a kind of folding-free aluminium-to-nickel lug, including aluminium strip 1, nickel strap 2, tab 3 and Protection glue 4, institute
State, between aluminium strip 1 and nickel strap 2, overlapping connecting portion 5 formed by welding manner, length L1 of described overlap connecting portion 5 is 1-3mm,
Described tab 3 is coated on aluminium strip 1 upper and lower surface, and described Protection glue 4 is coated on following table on overlapping connecting portion 5 by hot pressing mode
Face, described overlap connecting portion 5 lower end is 0.1-1mm apart from tab 3 apart from M1, and length L2 of described Protection glue 4 is 2-
4mm, the thickness of described Protection glue 4 is 30 μm -80 μm, and one end of described Protection glue 4 to tab 3 corresponding end apart from M2 is
0.1-1mm.The material of described Protection glue 4 is one of PE, PP, CPP, PET and PVC.It should be noted that described Protection glue 4
It is not limited by hot pressing mode and be coated on overlapping connecting portion 5 upper and lower surface it is also possible to overlapping connection is coated on by bonding method
Portion 5 upper and lower surface.
The above, be only preferred embodiment of the present utility model, not in order to limit this utility model, thus every
