Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in figure 1, a kind of detecting system of lithium ion battery cell welding quality, including casing 1 and case lid 2, this two
Person is assembled into seal cavity, is provided with and gas injection apparatus 4 and trachea 5 that source of the gas 6 connect is dried；Setting in described casing 1
There is quantitative liquid 7, this liquid 7 typically adopts water, the battery core that the amount of this liquid 7 puts into enough was covered completely.Gas injects
Device 4 is air gun.
Wherein, described casing 1 is additionally provided with air bleeding valve 8.For discharging the gas in casing 1.Also may be used by air bleeding valve 8
To connect with a gas collector, it is recovered to that source of the gas 6 is dried is recycled after exsiccator 9 is dried.
Wherein, described casing 1 is provided with barometer.Pressure in measurement casing 1.
Wherein, also include placing the rack for cleaning 3 of battery core, described rack for cleaning 3 is provided with the shelf of v font, makes battery core be in v word
Shape arrangement is placed.
A kind of detection method of lithium ion battery cell welding quality, in the matting after battery liquid-filling sealing, bag
Include following steps:
Step 1, injects liquid 7 in casing 1, and the injection rate of described liquid 7 is the 1/2 ~ 3/4 of casing 1 height, according to electricity
The amount of core is determining it is necessary to ensure that liquid 7 covered battery core completely；
Step 2, rack for cleaning 3 is immersed in casing 1 together with battery core, and battery core was covered completely by described liquid 7, then by case
Body 1 seals；
Step 3, is filled with dry gas into casing 1, till making the pressure in casing 1 reach 0.1 ~ 10mpa, and stands
15 ~ 30min, preferably 20min；
Step 4, to casing 1 aerofluxuss and take out battery core, observing whether battery core is heaved, if heaved, being failure welding, no
It is then that welding is qualified.Wherein, in described step 4, dried up in 3min after battery core is taken out.The described operation drying up is included just
Step dries up and dries up completely, and tentatively drying up is using air gun, the just face of battery core tentatively to be dried up, and drying up completely is to use to blow
Dry machine dries up to battery core.Battery core surface must be the noresidue globule, and could circulate lower operation.
Wherein, the water temperature of described liquid 7 is 30 ~ 45 DEG C.Suitable water temperature can enable the battery core of failure welding produce
Heave and be conducive to battery core surface clean.
Wherein, in rack for cleaning 3, leave the space of 1-3mm between the often row battery core placed.Make liquid 7 abundant
Soak and act on each battery core, the battery core of fully induction failure welding is heaved.
Detection process is also matting simultaneously, is being accomplished by afterwards changing using 3 ~ 5 times in liquid 7.And
After battery core dries up, in 20 minutes must secondary cleaning finish it is ensured that battery core soak time not long it is ensured that not seeping water.
Above embodiment simply indicates that rather than limits this utility model, thus all according to this utility model patent application
Equivalence changes or modification that method described in scope is done, are all included in this utility model patent claim.
