Abstract
The utility model provides an conjuncted utmost point ear, includes anodal ear strap and negative pole ear strap, and a anodal ear strap and a negative pole ear strap constitute a utmost point ear group, and anodal ear strap and negative pole ear strap are arranged side by side according to the interval of design requirement, and a plurality of utmost point ear group aligns the row according to the both ends of utmost point ear strap, and the centre is connected into conjuncted combination utmost point ear finished product area by a long utmost point ear adhesive tape. When the lithium battery packaging structure is used, one pole lug group is used for one lithium battery, and the pole lug adhesive tapes are shared by the positive pole lug and the negative pole lug, so that the distance between the positive pole lug and the negative pole lug is ensured in the previous process of lithium battery packaging, the later packaging process is reduced, the difficulty in locating the pole lug in the packaging process is reduced, and the occurrence of the packaging quality problem caused by overlapping of the pole lug adhesive is reduced. And the method provides guarantee for the production of high-quality lithium batteries.
Description
Technical Field
The utility model relates to a lithium battery technology, especially a conjuncted utmost point ear.
Background
The positive and negative electrode tabs of the conventional flexible-package lithium battery are split, namely the positive electrode tabs and the negative electrode tabs are respectively arranged in different packaging discs. When the positive lug is produced, the positive lug or the negative lug can only be produced on one lug forming machine at the same time and cannot be produced simultaneously due to different materials of the positive lug and the negative lug. For the positive and negative electrode lugs with the metal bandwidth less than 2mm, the top seal width of the lithium battery is very small, the positioning difficulty of the center distance of the positive and negative electrode lugs is very high during top seal, and the most serious quality problems of poor lithium battery packaging or liquid leakage or swelling are easily caused by the overlapping of lug glue at the middle parts of the positive and negative electrode lugs.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to prior art not enough, has provided a conjuncted utmost point ear of convenient location equipment.
The to-be-solved technical problem of the utility model is realized through following technical scheme, an conjuncted utmost point ear, including anodal ear strap and negative pole ear strap, its characteristics are: a positive lug metal belt and a negative lug metal belt form a lug group, the positive lug metal belt and the negative lug metal belt are arranged side by side according to the interval of the design requirement, a plurality of lug groups are arranged in a line by aligning the two ends of the lug metal belt, and the middle part of the lug group is connected into a conjoined combined lug finished product belt by a long lug adhesive tape.
The to-be-solved technical problem of the utility model can also be further realized through following technical scheme, and the interval between the adjacent utmost point ear group equals.
The to-be-solved technical problem of the utility model can also be realized through following technical scheme, utmost point ear adhesive tape combine hot melt to link together and constitute by the adhesive tape that sets up at utmost point ear strap tow sides.
Compared with the prior art, the utility model, constitute conjuncted combination utmost point ear finished product area by utmost point ear adhesive tape connection by positive negative pole ear group, utmost point ear group uses a lithium cell when using, and its utmost point ear adhesive tape is positive negative pole ear sharing, and the interval between the positive negative pole ear has just been guaranteed to the preceding one process of lithium cell encapsulation like this, has reduced later stage packaging process, has reduced the degree of difficulty of utmost point ear location in the packaging process, has reduced utmost point ear and has glued the appearance of overlapping the encapsulation quality problem that causes. And the method provides guarantee for the production of high-quality lithium batteries.

Fig. 1 is a schematic view of the present invention.
Detailed Description
The following further describes particular embodiments of the present invention to facilitate further understanding of the present invention by those skilled in the art, and does not constitute a limitation to the right thereof.
The utility model provides an conjuncted utmost point ear, includes anodal ear strap and negative pole ear strap, and a anodal ear strap and a negative pole ear strap constitute a utmost point ear group, and anodal ear strap and negative pole ear strap are arranged side by side according to the interval of design requirement, and a plurality of utmost point ear group aligns the row according to the both ends of utmost point ear strap, and the centre is connected into conjuncted combination utmost point ear finished product area by a long utmost point ear adhesive tape.
The spacing between adjacent pole ear groups is equal.
The tab adhesive tape 2 is formed by combining and hot-melting adhesive tapes arranged on the front surface and the back surface of the tab metal belt 1.
The utility model discloses a conjuncted utmost point ear mainly used positive pole ear strap width less than or equal to 2mm, use under the very little condition of width of lithium cell top seal.
The metal band of the positive electrode tab is generally an aluminum band, and the metal band of the negative electrode tab is generally a nickel band or a copper nickel plating band. The thickness of the positive electrode lug metal strip and the negative electrode lug metal strip is 20-60 mu m.
Claims (3)
1. The utility model provides an conjuncted utmost point ear, includes anodal ear strap and negative pole ear strap, its characterized in that: a positive lug metal belt and a negative lug metal belt form a lug group, the positive lug metal belt and the negative lug metal belt are arranged side by side at intervals, a plurality of lug groups are aligned at two ends of the lug metal belts and are connected into a conjoined combined lug finished product belt by a long lug adhesive tape in the middle.
