Mouth.The flowing structure band containing flowing water, fixed plate and lifting fixed hurdle, the cell fixing device gassiness pumping adnexa and fixation
Case, the fixed case connect air pump absorber.The battery filters hole between the mesuring battary and fixed case.
Further the leak-checking apparatus includes elevating mechanism, asepwirator pump and the component that leaks hunting, and the elevating mechanism connects institute
The component that leaks hunting is stated, leak hunting component mouth containing skin, tracheae, the first valve, the second valve and air pressure detector, and leak-checking apparatus, which is used, judges electricity
Whether whether the principle detection battery of gas leakage has leakage in pond.
Further, the refill mechanism can fix a battery every time.Refill mechanism fixed hurdle containing lifting, transmission
Band, lifting fixed hurdle release a battery every time, ibid the also next battery in column.
Further, the asepwirator pump draws a small amount of gas of quota every time, the air pressure in battery is less than atmospheric gas pressure,
When the air pressure in battery is low or when vacuum, air pressure detector can show that an index comes out, if air pressure in battery
Identical with atmospheric gas pressure, this explanation battery has gas leakage to enter.
Further, after first valve is closed, second valve is opened, and makes the air pressure detector connection electricity
Pond, the second valve coordinate operation of leaking hunting by opening and closing operations.
Further, the console is connected with air pressure detector, and the console determines whether to detect from air pressure
The signal of instrument, when there is signal, booster air pump absorber takes away battery.
Further, behind elevating mechanism alignment battery liquid-filling hole, skin mouth seals battery liquid-filling hole and reached the skin mouth
To sealing effectiveness.
Further, skin mouth uses toughening rubber material, and diameter is more than liquid injection port, less than the narrow side of mesuring battary, realization pair
The effect of battery port sealing.
Further, the elevating mechanism control leak-checking apparatus moves up and down, and realizes the down alignment function for starting to leak hunting
And terminate the disengaging action after leaking hunting.
Brief description of the drawings
Fig. 1 is the automatic leak-checking apparatus structural representation of lithium ion battery of the utility model embodiment.
Embodiment
The utility model is described in detail below with reference to specific embodiments and the drawings.
Referring to Fig. 1, a kind of automatic leak-checking apparatus 100 of lithium ion battery is shown, containing leak-checking apparatus 20, console 80, stream
Water dispenser structure 50, cell fixing device 40 and battery filtering hole 60, the console 80 connect leak-checking apparatus 20, the leak-checking apparatus
20 include elevating mechanism 28, asepwirator pump 21 and the component 29 that leaks hunting, and the elevating mechanism 28 connects the component 29 that leaks hunting, group of leaking hunting
The mouth containing skin of part 29 24, tracheae 23, the first valve 22, the second valve 27 and air pressure detector 26.First valve 22 connects institute
Asepwirator pump 21 is stated, the second valve 27 connection air pressure detector 26, the tracheae 23 connects skin mouth 24, and the flowing structure 50 is containing stream
Water band 51, fixed plate 52 and lifting fixed hurdle 70, the gassiness pumping adnexa 41 of cell fixing device 40 and fixed case 40 are described
Fixed case 40 connects air pump absorber 41.The battery filters hole 60 between the mesuring battary 30 and fixed case 40.
Further, mesuring battary 30 is transmitted to position to be measured by flowing water band 51, lifting fixed hurdle 70, which is fallen, stops electricity
Pond makes mesuring battary 30 stop moving ahead, while following flowing water band 51 also stops moving ahead, and air pump absorber 41 is close to battery and inhales
Attached firmly battery, while also fixed battery, the elevating mechanism 28 in leak-checking apparatus 20 puts down side leakage component 29, makes side leakage group
The liquid injection port 31 on skin mouth alignment mesuring battary 30 on part 29, now opens aspiration pump 21, when aspiration pump 21 is extracted in battery
A certain amount of air scoop, mesuring battary air pressure inside is relatively low, now closes the first valve 22, opens the second valve 27, makes gas
Press detector 26 to connect mesuring battary 30, when air pressure detector 26 detects that battery air-pressure is less than air pressure, then show
Battery will not leak, if detecting that battery air-pressure is equal to air pressure, illustrate that air has been leaked into battery, this
When air pressure detector 26 send a signal to console 80, can booster air pump absorption after console 20 receives signal
10 centimeters of 41 back shrinkage of device, its battery adsorbed can be in the top in battery filtering hole 60, and air pump absorber 41 unclamps absorption
Power, unqualified battery is allowed to fall into battery filtering hole 60.
Further, when air pressure detector 26 detects that air pressure is less than atmospheric gas pressure in mesuring battary, or keep stable
State when, can determine whether battery No leakage, rear lifting mechanism 28 side leakage component 29 is risen, lifting fixed hurdle 70 also rise,
