Abstract
A kind of lithium ion battery tab welding positioning fixture, manufactured for lithium ion battery.Positive pole ear groove, negative lug groove, battery core groove are distributed with fixture carrier；Battery core groove is located at fixture carrier side, and positive pole ear groove and negative lug groove are located at fixture carrier opposite side；Positive pole ear groove, negative lug groove are made up of lug glue groove position and lug metal part groove position.The correspondence position that the battery core of lithium ion battery and positive pole ear, negative lug are respectively positioned at fixture carrier by the utility model carries out positioning welding, the size of each groove position of fixture can be adjusted according to different process design criterias, it is simple in construction, it is easy to operation, labor intensity can effectively be reduced, production efficiency and lithium ion battery cell tab welding precision are increased substantially, ensures lug location consistency, lifts the welding quality of lithium ion battery.
Description
Technical field
Technical field of lithium-ion battery is the utility model is related to, is specifically that one kind is folded for flexible packing lithium ion battery
In blade technolgy, battery pole ear positioning fixture for welding.
Background technology
At present, lithium ion battery manufacture industry, especially with flexible-packed battery lamination process manufacturer to electricity
All it is to use manual positioning operation when core carries out tab welding, high to operating personnel's technical requirements, labor intensity is big, there is one
Fixed potential safety hazard, and lug position disunity after welding, cause product appearance inconsistent, have had a strong impact on product quality.
The content of the invention
For overcome the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of lithium ion cell polar ear weldering
Positioning fixture is connect, to improve the welding quality of lithium ion battery cell lug.
For achieving the above object, be distributed with fixture carrier of the present utility model positive pole ear groove, negative lug groove,
Battery core groove.
The battery core groove is located at the side of fixture carrier, and positive pole ear groove and negative lug groove are located at the another of fixture carrier
Side.
The positive pole ear groove, negative lug groove are made up of lug glue groove position and lug metal part groove position.
The positive pole ear groove, the position of negative lug groove and lithium ionic cell positive pole ear, negative lug are relative to lithium
The position consistency of ion battery battery core, positive pole ear groove, negative lug groove are vertical with fixture carrier width direction, positive pole ear
Groove, the lug metal part groove bit width of negative lug groove are consistent with the width of lithium ionic cell positive pole ear, negative lug, pole
The width and length of ear glue groove position are consistent with lithium ionic cell positive pole ear, the tab width of negative lug and length, depth
For 1mm-2mm；Battery core groove is that groove, battery core well width and depth and lithium ion battery cell are supporting.
The utility model is compared with prior art, fixed respectively by the battery core of lithium ion battery and positive pole ear, negative lug
Position carries out positioning welding in the correspondence position of fixture carrier, can adjust each groove position of fixture according to different process design criterias
Size, it is simple in construction, it is easy to operation, labor intensity can be effectively reduced, increases substantially production efficiency and lithium ion battery cell
Tab welding precision, ensure lug location consistency, lift the welding quality of lithium ion battery.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 rearview.
Embodiment
As shown in Figure 1 and Figure 2, positive pole ear groove 1, negative lug groove 2, electricity are distributed with fixture carrier 3 of the present utility model
Core groove 4；The battery core groove 4 is located at the side of fixture carrier 3, and positive pole ear groove and negative lug 2 are located at the another of fixture carrier 3
Side；The positive pole ear groove 1, negative lug groove 2 are made up of lug glue groove position 5 and lug metal part groove position 6；The positive pole pole
Ear slot 1, position and the lithium ionic cell positive pole ear of negative lug groove 2, negative lug relative to lithium ion battery cell position
Put unanimously, positive pole ear groove 1, negative lug groove 2 are vertical with the width of fixture carrier 3, positive pole ear groove 1, negative lug groove 2
The width of lug metal part groove position 6 it is consistent with the width of lithium ionic cell positive pole ear, negative lug, lug glue groove position 5
Width and length are consistent with lithium ionic cell positive pole ear, the tab width of negative lug and length, depth 1mm-2mm；
Battery core groove 4 is groove, the width of battery core groove 4 and depth width and depth design according to lithium ion battery.
During welding, the battery core of lithium ion battery is positioned in the battery core groove 4 of fixture carrier 3, and ensures cell polar ear end
Barrier film edge is concordant with the side of battery core groove 4, and positive pole ear groove 1 aligns with battery core anode ear position, negative lug groove 2 and battery core negative pole
Ear position is alignd, and first positive pole ear is placed in positive pole ear groove 1, now anode ear tab outer edge and cell polar ear end barrier film
Concordantly, battery core, positioning fixture for welding, positive pole ear are clutched with hand and carries out positive pole ear welding with bonding machine, then with same
Method carries out negative lug welding.
