Description
Technical field
The utility model relates to lithium battery pole ear, particularly relates to a kind of aluminium-to-nickel lug.
Background technology
The material normally fine aluminium of the positive pole ear of soft-packaged polymer lithium ion battery.Battery needs when processing assembling to be connected with other electron component by the both positive and negative polarity of battery by the mode of welding, but the positive pole ear be made up of fine aluminium directly can not carry out scolding tin.Existing technique normally welds one section of nickel strap at the exit of cell positive pole ear, then carries out soldering by nickel strap, and this technique is called as the positive pole ear aluminium-to-nickel technique of soft-packaged polymer lithium ion battery.
The positive pole ear aluminium-to-nickel technology of existing soft-packaged polymer lithium ion battery has two kinds of basic modes, one be aluminium pole ears in the fabrication process, by lug, nickel strap is soldered to positive pole ear by laser-beam welding machine by manufactory, produces single aluminium-to-nickel lug; Another kind is that aluminium pole ears does not carry out aluminium-to-nickel technique in lug manufactory, is directly produced into aluminium pole ears that is single or disc type, after cell manufacturer adopts this kind of lug to be produced into battery core, then carries out aluminium-to-nickel technique by metal ultrasonic bonding machine or laser-beam welding machine.But the mode of front a kind of aluminium-to-nickel causes cell manufacturer in battery core manufacturing process need drop into a large amount of people's force-summing devices carrying out welding of lug and battery core pole piece.In the mode of rear a kind of aluminium-to-nickel, disc type aluminium pole ears can use the automatic pelleter of battery to carry out welding of lug and battery core pole piece, thus realize automated production, but after battery core is made, need to drop into a large amount of people's force-summing devices and carry out aluminium-to-nickel technique, not only inefficiency, and easily cause battery core to scrap when carrying out the welding sequence of aluminium-to-nickel.
Utility model content
For solving the problem, the utility model provides that a kind of structure is simple, production efficiency is high, is convenient to the disc type aluminium-to-nickel lug of battery automatic pelleter assembling battery core.
A kind of disc type aluminium-to-nickel lug, comprises multi-disc aluminium strip and multi-disc nickel strap.Aluminium strip and nickel strap interval are arranged, adjacent aluminium strip and the lapping ends of nickel strap.Every sheet aluminium strip is fixed with tab on the position of one of them end, and tab stretches out from a side of aluminium strip.
Further, the width of aluminium strip is 1.5 ~ 10mm, and thickness is 0.1 ~ 0.2mm.
Further, the width of tab is 4 ~ 8mm, and thickness is 0.1mm.
Be connected by nickel strap between multiple aluminium pole ears of disc type aluminium-to-nickel lug of the present utility model, in the production process of battery, by automatic pelleter, disc type aluminium-to-nickel lug can be cut to single aluminium-to-nickel lug, thus realize automated production aluminium-to-nickel lug being applied to battery pole piece making.Therefore, when disc type aluminium-to-nickel lug of the present utility model is applied to the finished product assembling of battery, eliminates aluminium-to-nickel operation, and the automatic assembling of battery can be realized, thus save a large amount of human costs and production cost, also reduce the scrappage of battery core simultaneously.Therefore, disc type aluminium-to-nickel extreme ear structure of the present utility model is simple, production efficiency is high, be convenient to battery automatic pelleter assembling battery core.

Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the utility model disc type aluminium-to-nickel lug is described in further detail.
As depicted in figs. 1 and 2, in a preferred embodiment, disc type aluminium-to-nickel lug of the present utility model comprises multi-disc aluminium strip 1 and multi-disc nickel strap 3.Aluminium strip 1 and nickel strap 3 interval are arranged, adjacent aluminium strip 1 and the lapping ends of nickel strap 3.Every sheet aluminium strip is fixed with tab 2 on the position of one of them end, and tab 2 stretches out from a side of aluminium strip.
Lug manufactory can adopt following methods when manufacturing disc type aluminium-to-nickel lug:
Step 1: be first arranged at intervals with multiple tab 2 with equidistant on the aluminium strip of strip, position apart from each tab 2 one predeterminable range adopt the mode of laser welding or ultrasonic bonding to be welded on aluminium strip by one section of nickel strap 3, wherein the welding position of nickel strap and aluminium strip is the two ends of nickel strap, and the quantity of solder joint 4 is formulated according to the width of lug and technological requirement intensity.
Step 2: the aluminium strip overlapped in section with aluminium pole ears by the nickel strap welded by precision mould cutting machine is excised.Off-position as shown in Figure 2.
Step 3: precision mould cutting machine repeats step 2, until all aluminium strips overlapped with nickel strap are all cut, thus, formation multi-disc aluminium strip and multi-disc nickel strap interval are arranged, namely be connected by the nickel strap of welding between multiple aluminium level ear, thus made collapsible disc type aluminium-to-nickel lug.
Wherein, the width of nickel strap can be not identical with the width of aluminium strip.The length of nickel strap and aluminium strip can be formulated according to the actual requirements.The width of aluminium strip is 1.5 ~ 10mm, and thickness is 0.1 ~ 0.2mm.The width of tab is 4 ~ 8mm, and thickness is 0.1mm.
As shown in Figures 3 to 5, in the present embodiment, aluminium-to-nickel lug nickel strap of comprising aluminium strip, being arranged on the tab on aluminium strip and welding with aluminium strip on the position near tab.Specify to take the center of tab as the center of an aluminium-to-nickel lug hereinafter, the one end being welded with nickel strap is called the front end of tab; One end of welding nickel strap is called the rear end of tab.In the production process of battery, realize above-mentioned disc type aluminium-to-nickel lug to be cut into multiple single aluminium-to-nickel lug by the following method, and assemble with battery pole piece:
Steps A: in nickel strap 3 one end away from tab 2, adopts automatic pelleter to excise a part of aluminium strip, and the aluminium strip of excision comprises aluminium strip and nickel strap welding position.Thus, make to reserve one section of nickel strap 31 for scolding tin in the front end of tab 2.
Step B: the predeterminated position between tab 2 and the nickel strap of next aluminium pole ears, automatic pelleter is adopted to excise one section of aluminium strip, make to reserve one section of aluminium strip 11 for being connected with the pole piece 5 of battery in the rear end of tab 2, form an aluminium-to-nickel lug thus, be supplied to the assembling of battery pole piece.
Step C: repeat steps A and B by automatic pelleter, disc type aluminium-to-nickel lug is cut into multiple single aluminium-to-nickel lug, and is supplied to the assembling of battery pole piece, realize automated production.
Disc type aluminium-to-nickel lug of the present utility model, make in the production process of soft-packaged polymer lithium ion battery, automated production can be realized, solve in prior art the problem needing a large amount of cost of labor of input and equipment to carry out aluminium-to-nickel technique, thus improve the production efficiency of battery, not only reduce cost of labor, production cost, and reduce the scrappage of battery core.
