Description
Technical field
This utility model is related to cell art, more particularly to a kind of extreme ear structure.
Background technology
The positive pole ear of flexible package polymer battery is generally made using fine aluminium piece, therefore is also called aluminium pole ears.But aluminum pole
Ear can not directly carry out scolding tin when adding protection board or being connected with other electron component.Reason is that aluminum is very active, surface
Oxide layer once remove, new alumina layer can be generated again at once.Existing technique is typically in the extraction of battery aluminium pole ears
One section of nickel strap of end welding, then soldering is carried out by nickel strap, this technique is referred to as the positive pole ear aluminum of flexible package polymer battery and turns
Nickel technique.
Existing aluminium-to-nickel technique has two kinds of basic modes, the first be aluminium pole ears in the fabrication process, by lug manufacture
Nickel strap is soldered to aluminium pole ears by laser-beam welding machine by factory, produces single aluminium-to-nickel lug；Second is aluminium pole ears in pole
Ear maker does not carry out aluminium-to-nickel technique, is directly produced into the aluminium pole ears of single or rolling, and cell manufacturer adopts this kind of lug
After producing into battery core, then aluminium-to-nickel technique is carried out by ultrasonic welding machine or laser-beam welding machine.But two ways is present
Defect：In the mode of the first aluminium-to-nickel, cell manufacturer need to put into substantial amounts of people's force-summing device and carry out lug and battery core pole piece
Welding；In the mode of second aluminium-to-nickel, though rolling aluminium pole ears can carry out lug and battery core using the automatic pelleter of battery
The welding of pole piece, so as to realize automated production, but after battery core is made, needing also exist for putting into substantial amounts of people's force-summing device carries out aluminum
Turn nickel technique, not only inefficiency, and easily occur lug fracture when the welding sequence of aluminium-to-nickel is carried out or bore a hole, cause
Battery core is scrapped.
Therefore, prior art existing defects, need to improve.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of extreme ear structure.
The technical solution of the utility model is as follows：This utility model provides a kind of extreme ear structure, including：First aluminium strip,
Two aluminium strips and nickel strap, first aluminium strip are arranged to U-type groove with the nickel strap connection end, and second aluminium strip is connected with the nickel strap
Connect end and be arranged to U-type groove, described nickel strap one end is embedded in the U-type groove of the first aluminium strip, and the other end is embedded in the U-shaped of the second aluminium strip
In groove, first aluminium strip and second aluminium strip are compounded with tab, and two tabs are close to the nickel strap
Two ends.
The nickel strap two ends are corner.
The nickel strap two ends are fillet.
The position that first aluminium strip and the second aluminium strip are connected with the nickel strap is equipped with reinforcing strip.
The recess of extrusion molding is also formed with the position that first aluminium strip is connected with the nickel strap with the second aluminium strip.
The extreme ear structure provided using such scheme, this utility model, by laser welding, ultrasonic bonding, electric resistance welding
The mode such as connect to couple together to form a kind of extreme ear structure by aluminium strip and nickel strap, the lug of the structure causes battery to assemble in finished product
Cheng Zhong, eliminates aluminium-to-nickel operation, so aluminium strip not there is a problem of causing lug to rupture due to aluminium-to-nickel operation yet.Exist simultaneously
The extreme ear structure can be wound into lug coiled strip in battery production, by the automatic pelleter of battery by lug coiled strip continuous cutting-off be
Single lug, is applied to the automated production of pole piece making, greatly improves the production efficiency of battery, reduces and produce into
This, and improve the qualification rate of finished product.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Fig. 1 to Fig. 4 is referred to, this utility model provides a kind of extreme ear structure, including：First aluminium strip 1,2 and of the second aluminium strip
Nickel strap 3.First aluminium strip 1 is arranged to U-type groove with 3 connection end of the nickel strap, and second aluminium strip 2 is connected with the nickel strap 3
End is arranged to U-type groove, and 3 one end of the nickel strap is embedded in the U-type groove of the first aluminium strip 1, and the other end is embedded in the U of the second aluminium strip 2
In type groove, using the structure, after welding, nickel strap 3 is contacted with the first aluminium strip 1, the second aluminium strip 2 more preferably, is connected more firm.It is described
First aluminium strip 1 and second aluminium strip 2 are compounded with tab 4, two ends of two tabs 4 close to the nickel strap 3,
Tab 4 is MODIFIED PP, and the purpose of compound tab 4 is to make the MODIFIED PP on lug encapsulate work in battery core with plastic-aluminum film inner layer PP
