Tool.
Background technique
Battery core principal length, width, tab position, the tab length, gel of prior art polymer Li-ion battery
The inspection of higher size needs two procedures to test tool completion using two kinds.Battery core used at present, which is tested to have, examines main body long
Spend function, it usually needs the inspection tooling of additional production battery core principal length.Needing to expend two manpowers in process could complete
Battery core items dimension control.
Factory reduces human cost to improve working efficiency, the overall dimension for needing only to need a people that battery core can be completed
The tool of inspection.
Utility model content
The utility model is in order to overcome the shortcomings in the prior art, to provide a kind of detection polymer lithium ion battery cell each portion
Size tests tool, realizes the rulers such as polymer lithium ion battery cell principal length, width, tab position, tab length, gel height
Very little inspection only needs a people can be completed.
The utility model to achieve the above object, is achieved through the following technical solutions, a kind of detection polymer Li-ion electricity
Each portion's size of core tests tool, including tests tool ontology, it is characterized in that: the tool ontology of testing is equipped with battery core groove, battery core groove top
Portion is equipped with step unit, and step unit lower bottom part sideline and groove lower edge line, which are constituted, examines battery core principal length upper distance limit L,
Groove two sides sideline, which is constituted, examines battery core width upper distance limit H, and step unit top is equipped with the positive and negative tab being parallel to each other
Detection slot, positive and negative tab detection slot position are corresponding with the positive and negative tab position of tested battery core.
The positive and negative tab detection slot depth M is greater than tested battery core back boss 11.
The positive and negative tab detection slot bottom is equipped with gel groove E.
The battery core depth of groove is greater than tested battery core thickness, and battery core groove quadrangle, which is equipped with, guarantees four side geometric accuracy of groove
Fabrication hole.
The utility model has the advantages that compared with prior art, the utility model battery core dimension control tooling can be achieved at the same time to battery core
Principal length and cell polar ear position, tab length, gel be high, the inspection of battery core overall length and battery core width.With original tooling
It compares, saves human cost, improve production efficiency.

Specific embodiment
In conjunction with the preferred embodiment, to according to specific embodiment provided by the utility model, details are as follows: being detailed in attached
Figure present embodiments provides a kind of detection polymer lithium ion battery cell each portion's size and tests tool, including tests tool ontology, described to test tool
Ontology is equipped with battery core groove, and battery core groove top is equipped with step unit, step unit lower bottom part sideline and groove lower edge line
It constitutes and examines battery core principal length upper distance limit L, L to examine battery core principal length 10, groove two sides sideline, which is constituted, examines electricity
Core width upper distance limit H, step unit top are equipped with the positive and negative tab detection slot being parallel to each other, positive and negative tab detection slot position
Set it is corresponding with the positive and negative tab position of tested battery core, for detecting tab width 3.The positive and negative tab detection slot depth M is greater than
Tested battery core back boss 11.The positive and negative tab detection slot bottom is equipped with gel groove E, to detect gel width 4.
The battery core depth of groove is greater than tested battery core thickness 9, and battery core groove quadrangle is equipped with the technique for guaranteeing four side geometric accuracy of groove
Hole 4-R1.5, it is therefore an objective to guarantee the verticality on four side of battery core groove.
Table 1 is that each section test position of the utility model identifies
The course of work
Battery core dimension control tooling, battery core reverse side is put into upwards and tests tool, according to battery core specific requirement with tooling side of the positive electrode
Or whether the positioning of cathode side, observation battery core items size are qualified.Existing battery core is tested into tool and body check tooling merges, according to
The utility model design rule combination battery core specific size requires to design and produce dedicated to test tool.
Step unit depth M should be greater than battery core back boss 11, so that battery core forward position 12 can place in parallel with reality step
Now to battery core without glue overall length 7, tab position 1,2, tab length 5, battery core width 6, battery core overall length containing glue 8, tab width 3 and
The inspection of gel width 4, while M should be no more than 0.5mm, i.e. 11 < M < 11+0.5mm greater than the amount of back boss 11, so that
Step height is consistent with battery core dell (thickness at 9-11- closedtop tab), guarantees effective inspection to battery core principal length.
Step described in the present embodiment is not laterally fully taking up groove, two sides stay there are two with test tool ontology and be integrated
2mm wide surplus, groove depth is consistent with main body groove depth K, be equal to battery core upper thickness limit, for examining battery core two sides
Length.
Since practical battery core is not regular cuboid, physical length, width etc. should take full-size, the length of each part
Degree, width 100% should be able to all be detected simultaneously.
Distance H is limited at left and right sides of tooling to examine battery core width, while can select side of the positive electrode or cathode as needed
Side positions battery core, to examine tab position etc..
It is above-mentioned referring to embodiment to this it is a kind of detection each portion's size of polymer lithium ion battery cell test tool carry out in detail retouch
It states, is illustrative without being restrictive, several embodiments can be enumerated according to limited range, therefore do not departing from this
Change and modification under utility model general plotting should belong within the protection scope of the utility model.
