Description
Technical field
The present invention relates to a kind of lithium ion battery production method, especially a kind of flexible packing lithium ion battery two spells core lug bending method.
Background technology
The mode that current flexible packing lithium ion battery two core splicing, welding, lug bending are taked, it is substantially and first welds the mode cutting last bending again, it is reserved long that splicing used two core lugs, Soft Roll are combined lug welding ends, cause waste of material, this welding manner is combined lug welding ends and is difficult to location front, welding could bend after need to cutting out, can not directly bend, and bending difficulty is big, after bending, lug easily protrudes, affect battery outward appearance after encapsulation, puncture aluminum plastic film time serious and cause battery to scrap.
Summary of the invention
The invention provides a kind of flexible packing lithium ion battery two reducing bending difficulty and material cost and spell core lug bending method.
The flexible packing lithium ion battery two realizing the object of the invention spells core lug bending method, comprises the steps:
(1) two core splicing: the two of flexible packing lithium ion battery core are closed up alignment, fixes with lithium ion battery special adhesive tape；Two lugs of the first core keep vertically, two lugs of the second core being against battery diaphragm, towards the lug bending 90 ° of the first core, and being close to the lug of the first core；After bending, the lug of the first core and the lug of the second core are combined into reserved lug；
(2) Soft Roll be combined lug with splicing core weld: with supersonic welder customize two Soft Rolls be combined the weld part of lug respectively at two reserved tab weldings；
(3) lug bending: postwelding Soft Roll is combined lug and reserved lug together againsts battery diaphragm to same direction curved 90 °, is then combined, Soft Roll, 90 °, the film lower edge that lug is combined lug along weld part top and Soft Roll and turns up；After twice bending, Soft Roll is combined lug and keeps vertical, and finally patch lithium ion battery special adhesive tape is fixed Soft Roll and is combined lug.
Described step (3) is combined, Soft Roll, the film lower edge 1mm gap location 90 ° that lug is combined lug along weld part top and Soft Roll and turns up.
The flexible packing lithium ion battery two of the present invention spells having the beneficial effect that of core lug bending method:
1, the flexible packing lithium ion battery two of the present invention spells core lug bending method, uses the mode that the reserved lug of first welding bends again, it is easy to welding location, it is easy to bending；
2, after bending, lug will not be protruding, provides convenient for following process；
3, the welding ends material that the lug of two core and Soft Roll are combined lug is short, saves material cost；
4, directly bend after welding, it is not necessary to cut, reduce one procedure, improve productivity ratio and processing cost.

Detailed description of the invention
The flexible packing lithium ion battery two of the present invention spells core lug bending method, comprises the steps:
(1) as it is shown in figure 1, two core are spliced: the two of flexible packing lithium ion battery core are closed up alignment, fix with lithium ion battery special adhesive tape 6；Two lugs 3 of the first core 1 keep vertical, and two lugs 4 of the second core 2 are against battery diaphragm 5, towards lug 3 90-degree bent of the first core 1, and are close to the lug 3 of the first core 1；After bending, the lug 3 of the first core 1 and the lug 4 of the second core 2 are combined into reserved lug；
(2) as shown in Figure 2,4, Soft Roll be combined lug 7 with splicing core weld: with supersonic welder customize two Soft Rolls be combined the weld part 71 of lug 7 respectively at two reserved tab weldings；
(3) as shown in Figure 2,3, lug bending: postwelding Soft Roll is combined lug 7 and reserved lug together againsts battery diaphragm to same direction curved 90 °, is then combined the 1mm gap location 90 ° of lower edge 8 of the film 72 that lug 7 is combined lug along weld part top 9 and Soft Roll Soft Roll and turns up；After twice bending, Soft Roll is combined lug 7 and keeps vertical, and finally patch lithium ion battery special adhesive tape is fixed Soft Roll and is combined lug 7.
Embodiment described above is only to be described the preferred embodiment of the present invention; not the scope of the present invention is defined; under design spirit premise without departing from the present invention; various deformation that technical solution of the present invention is made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present invention determines.
Claims (2)
1. flexible packing lithium ion battery two spells a core lug bending method, comprises the steps:
(1) two core splicing: the two of flexible packing lithium ion battery core are closed up alignment, fixes with lithium ion battery special adhesive tape；Two lugs of the first core keep vertically, two lugs of the second core being against battery diaphragm, towards the lug bending 90 ° of the first core, and being close to the lug of the first core；After bending, the lug of the first core and the lug of the second core are combined into reserved lug；
