Electrolyte is put into liquid storage mechanism, and liquid storage mechanism is connected to mechanism for filling liquid, and mechanism for filling liquid fixed by the first positioner, and mechanism for filling liquid is connected to li battery shell, and li battery shell fixed by the second positioner.Open mechanism for filling liquid, electrolyte can be expelled in lithium battery, and the operations such as battery carries out vacuumizing in vacuum tank, pressure release, electrolyte can be evenly distributed in battery, prevents from occurring in battery bubble, thus ensure that the useful life of battery.
Accompanying drawing explanation
Fig. 1 is a kind of overall structure schematic diagram of lithium battery priming device.
Embodiment
As shown in Figure 1, a kind of lithium battery priming device, comprises liquid storage mechanism 1, is positioned at the mechanism for filling liquid 2 below liquid storage mechanism 1, the first positioner 3 fixing mechanism for filling liquid 2 and the second positioner 4 be positioned at below the first positioner 3.Electrolyte is put into liquid storage mechanism 1, liquid storage mechanism 1 is connected to mechanism for filling liquid 2, and mechanism for filling liquid 2 fixed by the first positioner 3, and mechanism for filling liquid 2 is connected to li battery shell, and li battery shell fixed by the second positioner 4.Open mechanism for filling liquid 2, electrolyte can be expelled in lithium battery, and the operations such as battery carries out vacuumizing in vacuum tank, pressure release, electrolyte can be evenly distributed in battery, prevents from occurring in battery bubble, thus ensure that the useful life of battery.
Described liquid storage mechanism 1 comprises fluid reservoir 5, and fluid reservoir 5 is by being connected with mechanism for filling liquid 2 communicating pipe 6, and communicating pipe 6 is provided with valve 7.Open valve 7, electrolyte can by being injected in mechanism for filling liquid 2 communicating pipe 6, for being expelled in battery.The injection-tube 9 that described mechanism for filling liquid 2 comprises fluid reservoir 8 and is positioned at below fluid reservoir 8.Fluid reservoir 8 plays the effect temporarily stored, and can receive the electrolyte flowed out from fluid reservoir 5, can inject electrolyte by injection-tube 9 to battery.
Described first positioner 3 comprises and is positioned at the guide rail I 10 below fluid reservoir 8, the support bar 11 being positioned at guide rail I 10 both sides and the baffle plate I 12 perpendicular with guide rail I 10, be provided with slot I 13 in the middle of described guide rail I 10, baffle plate I 12 fixes fluid reservoir 8 through slot I 13.Fluid reservoir 8 is positioned on guide rail I 10, fluid reservoir 8 can adjust the position of putting along guide rail I 10, baffle plate I 12 can fix fluid reservoir 8 with coordinating of slot I 13, be convenient to mechanism for filling liquid 2 and the corresponding good position of lithium battery, thus ensure that the uniformity of the electrolyte in lithium battery, ensure that the useful life of lithium battery.
Described second positioner 4 comprises base plate 14, is fixed on the guide rail II 15 of the base plate 14 and baffle plate II 16 perpendicular with guide rail II15, slot II 17 is provided with in the middle of described guide rail II 15, baffle plate II 16 is movably connected on guide rail II 15 through slot II17, and guide rail II 15 and guide rail I 10 are perpendicular.Second positioner is used for fixing lithium battery, lithium battery can move along guide rail II 15, makes lithium battery good position corresponding to mechanism for filling liquid 2, speed during guarantee electrolyte inflow battery and stability, prevent from occurring bubble in battery, extend the useful life of lithium battery.
During use, electrolyte is put into liquid storage mechanism 1, liquid storage mechanism 1 is connected to mechanism for filling liquid 2, and mechanism for filling liquid 2 fixed by the first positioner 3, and mechanism for filling liquid 2 is connected to li battery shell, and li battery shell fixed by the second positioner 4.Open mechanism for filling liquid 2, electrolyte can be expelled in lithium battery, and the operations such as battery carries out vacuumizing in vacuum tank, pressure release, electrolyte can be evenly distributed in battery, prevents from occurring in battery bubble, thus ensure that the useful life of battery.
