Abstract
The invention discloses a method for manufacturing a positive electrode lug of a soft package lithium ion battery. The method comprises: making an aluminum strip and a nickel strip form an overlap area, and placing the overlap area in the welding zone of a laser machine; starting the laser machine to weld the overlap area of the aluminum strip and the nickel strip within the welding zone uniformly; slitting the welded aluminum-nickel strip vertically according to a needed specification by a slitting machine; subjecting the slit product to oil removing cleaning, surface protection and drying so as to obtain an aluminum-nickel strip welded body; pasting an electrode lug sealant to the welding joints of the aluminum-nickel strip welded body, thus obtaining a positive electrode lug. The method of the invention first welds the overlap area of an aluminum strip and a nickel strip uniformly by lasers, then conducts slitting through a slitting machine and pastes an electrode lug sealant to the welding joints of an aluminum-nickel strip welded body, thus not only enhancing the production efficiency of the positive electrode lug of a soft package lithium ion battery, but also improving the binding degree of a nickel sheet and an aluminum sheet. Further, by utilizing a laser welding machine for uniform welding, the method provided in the invention can reduce the occurrence of false welding or overwelding.
Description
Technical field
The present invention relates to electronic technology field, relate in particular to a kind of manufacture method of Soft Roll lithium ionic cell positive pole ear.
Background technology
Along with of a large amount of uses of Soft Roll lithium ion battery as a kind of novel lithium battery, to as the battery pole ear (following abbreviation " lug ") of the critical piece of Soft Roll lithium ion battery require increasingly high.
Lug is divided into both positive and negative polarity two parts, and the positive pole ear main material is made by the fine aluminium sheet, and the negative lug main material is made by pure nickel sheet (or copper sheet, nickel plating copper sheet).In normal environment, the aluminium flake of positive pole ear is scolding tin directly, thereby positive pole ear needs could to use by scolding tin behind the nickel of the commentaries on classics weldering earlier sheet.
Traditional Soft Roll lithium ion battery the manufacture craft of positive pole ear in, be through at topical nickel galvanization on the aluminium flake or be welded to the nickel sheet on the positive pole ear with ultrasonic bonding.Topical nickel galvanization complex process cost is higher, and ultrasonic welding process causes rosin joint easily or crosses weldering at the weld of nickel sheet and aluminium flake, and the efficient of producing positive pole ear is low.Therefore need to seek a kind of method that can replace above-mentioned positive pole ear production technology.
Summary of the invention
To the weak point that exists in the above-mentioned technology; The present invention provides a kind of manufacture method of Soft Roll lithium ionic cell positive pole ear; Can improve the production efficiency of Soft Roll lithium ionic cell positive pole ear and the conjugation of nickel sheet and aluminium flake, the generation that reduces rosin joint or cross the situation of welding.
For realizing above-mentioned purpose, the present invention provides a kind of manufacture method of Soft Roll lithium ionic cell positive pole ear, may further comprise the steps:
Make aluminium strip and nickel strap have the overlay region, and said overlay region is placed in the laser machine weld zone;
Starting the laser machine evenly welds the overlay region of aluminium strip in the weld zone and nickel strap;
Pass through the banding machine vertical itemize of specification as required to the good aluminium nickel strap of welding;
The product that said itemize is good obtains aluminium nickel strap welding body through oil removing cleaning, surface protection, oven dry;
Lug fluid sealant in the welded joint pressing of said aluminium nickel strap welding body obtains positive pole ear.
Wherein, make before aluminium strip and nickel strap have the step of overlay region, also comprise an end of aluminium strip and nickel strap respectively clamping to feeding machine, and pass through the step of locating clip clamping to the collecting machine to the other end of aluminium strip and nickel strap respectively.
Wherein, in the welded joint pressing of said aluminium nickel strap welding body, after the step of lug fluid sealant, also comprise the step of the aluminium nickel strap welding body of lug fluid sealant in the said pressing of finishing of cutting edge.
The invention has the beneficial effects as follows: compared with prior art; The manufacture method of Soft Roll lithium ionic cell positive pole ear provided by the invention; The aluminium strip and the nickel strap that at first will have an overlay region through laser evenly weld; Then through the banding machine itemize and in pressing on the joint portion of aluminium nickel strap welding body the lug fluid sealant, not only can improve the production efficiency of Soft Roll lithium ionic cell positive pole ear like this, and can improve the conjugation of nickel sheet and aluminium flake.Further, the present invention utilizes the even welding of laser-beam welding machine can also reduce rosin joint or crosses the situation of welding and takes place.

Embodiment
In order more clearly to explain the present invention, the present invention is done to describe further below in conjunction with accompanying drawing.
See also Fig. 1-Fig. 5, the present invention provides a kind of manufacture method of Soft Roll lithium ionic cell positive pole ear, may further comprise the steps:
Step 101: make aluminium strip and nickel strap have the overlay region, and the overlay region is placed in the laser machine weld zone;
Step 102: start the laser machine overlay region with aluminium strip in the weld zone and nickel strap as shown in Figure 3 and evenly weld;
Step 103: specification such as Fig. 4 carry out vertical itemize as required through banding machine the good aluminium nickel strap of welding;
Step 104: the product that itemize is good obtains aluminium nickel strap welding body through oil removing cleaning, surface protection, oven dry;
Step 105: lug fluid sealant in the welded joint pressing of aluminium nickel strap welding body obtains positive pole ear as depicted in figs. 1 and 2.
Situation compared to prior art; The manufacture method of Soft Roll lithium ionic cell positive pole ear provided by the invention; The aluminium strip and the nickel strap that at first will have an overlay region through laser evenly weld; Then through the banding machine itemize and in pressing on the joint portion of aluminium nickel strap welding body the lug fluid sealant, not only can improve the production efficiency of Soft Roll lithium ionic cell positive pole ear like this, and can improve the conjugation of nickel sheet and aluminium flake.Further, the present invention utilizes the even welding of laser-beam welding machine can also reduce rosin joint or crosses the situation of welding and takes place.
In another embodiment, make before aluminium strip and nickel strap have the step of overlay region, also comprise an end of aluminium strip and nickel strap respectively clamping to feeding machine, and pass through the step of locating clip clamping to the collecting machine to the other end of aluminium strip and nickel strap respectively.Adopt feeding machine and collecting machine to come transmitting-receiving aluminium strip and nickel strap automatically, realize automated production, can significantly improve production efficiency, reduce manual work intensity.
