Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
As shown in Figure 1 and Figure 2, for this utility model one preferred embodiment, this battery core priming device includes operating platform 1 He
Movably for placing the seal closure 2 of battery core 6, seal closure 2 is located on described operating platform 1, seal closure 2 or operating platform 1
On be equipped with and add pressure valve 21 and vacuum air valve 11.
Battery core 6 and reservoir container 7 are put into seal closure 2, and then seal closure 2 seals up, and vacuum air valve 21 starts to take out very
Sky, keeps certain time, then opens and add pressure valve 11, pressurizes a period of time, and so circulation is carried out, and can be battery core 6 injection process
Negative and positive pressure reciprocation cycle is provided, accelerates the seepage velocity of electrolyte, improve fluid injection efficiency, shorten the fluid injection time.
Specifically, operating platform 1 being additionally provided with fixed mount 3, fixed mount 3 is crossed on outside seal closure 2, and fixed mount 3 sets
There is driving motor 4, drive motor 4 to be connected with seal closure 2 by connecting shaft 5, and drive it to move up and down.As it is shown on figure 3, operation
Platform 1 is provided with movable clamp groove 12, and seal closure 2 lower end is provided with the card article 22 matched with movable clamp groove 12, increases sealing effectiveness.
Seal closure 2 is in rectangular structure, and card article 22 is located at seal closure 2 side wall lower ends.Movable clamp groove 12 is square setting.Movable clamp groove 12
Being provided with sealing plate 13 on inwall, sealing plate 13 can use silica gel material, and elastic packing increases sealing.In the present embodiment,
Adding pressure valve 11 and be positioned at seal closure 2 top, vacuum air valve 21 is positioned on operating platform 1.It is embedded with heater strip on seal closure 2 sidewall
23。
