Description
Technical field
This utility model is related to a kind of welding equipment, is exactly a kind of boiling hot hole pin of lithium battery production.
Background technology
In Production Process of Lithium Battery, after electrode winding is completed, in order to meet the needs to cathode of lithium battery weld job,
Generally require to carry out scalding hole weld job for lithium battery pole piece by special bore hole, by lithium battery pole piece center
Barrier film and electrode of lithium cell core electrode surface soldered, provide good operating condition for cathode of lithium battery weld job, but
Find in actual work, currently due to due to used boiling hot hole pin device structure, after carrying out scalding hole operation, barrier film is past
Occur toward can not effectively carry out being welded and fixed, be welded and fixed the phenomenons such as not in place and membrane surface is impaired, so as to cause lithium electricity
The product quality of the work efficiency of pond negative pole weld job and lithium battery, meanwhile, current boiling hot hole pin is often also tied for integral type
Structure, it is poor using motility, it is impossible to according to using needing flexibly to be controlled to scalding hole operation, can not to enter to scalding hole pin local
Row part replacement, using extremely inconvenience, and equipment fault repair rate is relatively low, therefore is directed to this phenomenon, in the urgent need to
A kind of new lithium battery production is developed with hole pin is scalded, to meet actually used needs.
The content of the invention
For not enough present on prior art, this utility model offer a kind of lithium battery production boiling hot hole pin, the practicality
New structure is simple, flexible and convenient to use, on the one hand with good use motility and part replacement ability, on the other hand
Effectively the barrier film inside lithium cell core can be positioned, it is to avoid the electrode of lithium cell welding caused because barrier film rebounds is unstable existing
As occurring.
To achieve these goals, this utility model is by the following technical solutions realizing：
A kind of production of lithium battery with scalding hole pin, including syringe needle, shank and connection ring, by connecting between described syringe needle, shank
Connect ring to be connected with each other, syringe needle, shank and connection ring are coaxially distributed, needle length is 13 millimeters, and syringe needle is conical structure,
Shank is cylindrical structure, sets connecting cavity in shank, and the uniform open-work of outer surface, wherein connecting cavity are coaxially distributed with shank, open-work
Connect with connecting cavity, and open-work axis and connecting cavity vertical distribution, open-work is distributed in the shape of a spiral around shank axis, before connection ring
End face diameter is identical with syringe needle end diameter, and rear end face diameter is identical with shank diameter, between connection ring front end face and rear end face is
Arc surface structure.
Further, described shank end sets adpting flange.
Further, it is threaded connection between described connection ring and syringe needle, shank.
This utility model simple structure, it is flexible and convenient to use, on the one hand with good use motility and parts more
Transducing power, on the other hand effectively can position to the barrier film inside lithium cell core, it is to avoid the lithium electricity caused because barrier film rebounds
Pond electrode welding shakiness phenomenon occurs.
