Abstract
The utility model provides a kind of simple structure, is easy to the automatic pelleter of battery to assemble the aluminium-to-nickel lug of battery core, including spaced aluminium strip and nickel strap, and aluminium strip two ends are welded with nickel strap；Aluminium strip one end is provided with tab, and the tab stretches out from two sides of aluminium strip；Aluminium strip is provided with and Protection glue is additionally provided with one end of tab, and Protection glue is covered in aluminium strip nickel strap weld, and simultaneously aluminium coating with being left white part between nickel strap weld and tab.When the finished product for being applied to battery using aluminium-to-nickel lug of the present utility model is assembled, tension, anti-folding and the shear strength that part is left white on aluminium-to-nickel lug can be strengthened, solve the problems, such as that lug pierces through aluminum plastic film, reduce the phenomenon of lug broken belt when automatic pelleter is produced, so as to improve production efficiency, the scrappage of battery core is reduced.
Description
Technical field
The utility model is related to lithium battery pole ear, more particularly to a kind of aluminium-to-nickel lug.
Background technology
The material of the positive pole ear of soft-packaged polymer lithium ion battery is typically fine aluminium.Battery needs when assembling is processed
The both positive and negative polarity of battery is connected with other electron component by way of welding, but can not be straight by the positive pole ear that fine aluminium is made
Tap into row scolding tin.Existing technique is typically to weld one section of nickel strap in the exit of cell positive pole ear, then is carried out by nickel strap
Soldering, this technique is referred to as the positive pole ear aluminium-to-nickel technique of soft-packaged polymer lithium ion battery.
The basic mode of the positive pole ear aluminium-to-nickel technology of existing soft-packaged polymer lithium ion battery is：Aluminium pole ears exist
In manufacturing process, nickel strap is soldered to by positive pole ear by laser-beam welding machine by lug manufactory, and by positive pole ear from beginning to end
It is connected with laser spot welding, produces aluminium-to-nickel lug；But, aluminium-to-nickel lug is mainly the automatic system for being applied to lithium battery electric core
Piece machine carries out automated production, easily occurs problems with process of production：
1. the speed of service of automatic pelleter is fast, and production efficiency is high, but due to aluminium-to-nickel lug aluminium nickel overlapping part to pole
Ear glue be left white part after by the roller group of automatic pelleter discharge mechanism and aligning gear, to being left white part（Material
It is fine aluminium）There is tensile strength requirement higher；
2. battery core in pack operations, it is necessary to by lug reflexed to battery core package position and fixed, it is therefore an objective to it is convenient to install
Protection board and by tab welding to protect plate electrode on.After reflexed, the laser spot welding position of lug can touch electricity to lug
The aluminum plastic film of core, if laser spot welding position is jagged, it is possible to can pierce through aluminum plastic film, causes battery core to be scrapped.Meanwhile, pole
Ear, it is necessary to adjust the position of lug repeatedly, is then left white the anti-folding at position and anti-in reflexed and welding protection plate to lug
Cutting intensity has requirement higher.
Utility model content
To solve the above problems, the utility model provides a kind of simple structure, is easy to the automatic pelleter assembling battery core of battery
Aluminium-to-nickel lug, including spaced aluminium strip and nickel strap, aluminium strip two ends are welded with nickel strap；Aluminium strip one end is provided with tab,
The tab stretches out from two sides of aluminium strip；Aluminium strip is provided with and Protection glue is additionally provided with one end of tab, Protection glue
Be covered in aluminium strip nickel strap weld, and simultaneously aluminium coating with being left white part between nickel strap weld and tab.
Preferably, the Protection glue includes being covered each by the upper glue layer and lower glue layer in aluminium strip two sides.
Preferably, the width of the aluminium strip is 1.5 ~ 10mm, and thickness is 0.1 ~ 0.2mm.
Preferably, the width of the Protection glue is 3 ~ 8mm, and thickness is 0.08~0.1mm.
Therefore, when the finished product for being applied to battery using aluminium-to-nickel lug of the present utility model is assembled, aluminium-to-nickel can be strengthened
Tension, anti-folding and the shear strength of part are left white on lug, solve the problems, such as that lug pierces through aluminum plastic film, reduce automatic film-making
The phenomenon of lug broken belt, so as to improve production efficiency, reduces the scrappage of battery core when machine is produced.
Brief description of the drawings
The aluminium-to-nickel lug embodiment schematic diagram that Fig. 1 is provided for the utility model.
Fig. 2 is the sectional view of aluminium-to-nickel lug embodiment in Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing.
Aluminium-to-nickel lug, including spaced aluminium strip 1 as shown in Figure 1, 2 and nickel strap 2, the width of aluminium strip 1 is 6mm, thick
It is 0.2mm to spend；Welded with nickel strap 2 at the two ends of aluminium strip 1；The one end of aluminium strip 1 is provided with tab 3, tab 3 from two sides of aluminium strip 1 to
Outer extension；Aluminium strip 1 is provided with and Protection glue 4 is additionally provided with one end of tab 3, and Protection glue 4 is covered in aluminium strip nickel strap weld 5,
The width of Protection glue 4 is 8mm, thickness 0.1mm.And simultaneously aluminium coating with being left white part between nickel strap weld 5 and tab 3
6.Protection glue 4 includes being covered each by the upper glue layer 41 and lower glue layer 42 in the two sides of aluminium strip 1, and the tension that part 6 is left white to strengthen resists
Folding and shearing strength.
Although being carried out with reference to embodiments above to description of the present utility model, it is familiar with the art
Personnel many replacements, modifications and variations can be carried out according to above-mentioned content, be obvious.Therefore, it is all such
Substitute, improve and change and be included in the spirit and scope of appended claims.
