Description
Technical field:
The utility model is a kind of device that is applicable to column lithium ion battery filling electrolyte.
Background technology:
At present, the mode of column lithium ion battery filling electrolyte is had two kinds, a kind of is artificial filling, and the problem of existence is that production effect is low, easily takes place to leak to annotate phenomenon; Another kind is to adopt the filling of electrolyte automatic filling machine, but because its complex structure costs an arm and a leg, also can't once finish fluid injection, is not generally promoted.
Summary of the invention:
The purpose of this utility model provide a kind of simple in structure, price is low, can once finish the cylinder type lithium ion battery electrolytic solution automatic filling machine of fluid injection.Technical solution of the present utility model is, it includes an electrolyte container and a liquid injection pipe, it is characterized in that: the electrolyte container bottom is communicated with on the inlet of an ELECTROMAGNETIC VACUUM rotary valve, the liquid injection pipe upper end is communicated with on the liquid outlet of ELECTROMAGNETIC VACUUM rotary valve, in valve body, a liquid injecting mouth is installed downwards around liquid injection pipe, be provided with sealing ring between liquid injecting mouth and the valve body, in the liquid injecting mouth lower end lower seal is installed, side at storage liquid mouth is provided with unidirectional valve, a vacuum tube is installed in the lower seal centre bore, be interconnected between vacuum tube and the unidirectional valve, the lower end of unidirectional valve and liquid injection pipe is installed in the centre bore of lower seal side by side by vacuum tube respectively.The utlity model has simple in structurely, easy to operate, can once finish electrolyte filling, help improving automaticity and reduce production costs.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Describe embodiment in conjunction with the accompanying drawings in detail.The utility model is to be communicated with on the inlet of an ELECTROMAGNETIC VACUUM rotary valve 6 in the bottom of an electrolyte container 5, the upper end of liquid injection pipe 9 is communicated with on the liquid outlet of ELECTROMAGNETIC VACUUM rotation, on the liquid injection pipe of the bottom of valve body 4, in valve body, a liquid injecting mouth 2 is installed downwards around liquid injection pipe, be provided with sealing ring 3 between liquid injecting mouth and the valve body, a lower seal 1 is installed in the liquid injecting mouth lower end, side at liquid injecting mouth is provided with unidirectional valve 7, a vacuum tube 8 is installed in the lower seal centre bore, be interconnected between unidirectional valve and the vacuum tube, liquid injection pipe and unidirectional valve and lower end are installed in the centre bore of lower seal side by side by vacuum tube respectively.During work, by topping-up pump electrolyte is joined in the electrolyte container, simultaneously unidirectional valve is connected on the vacuum pump, and the sealing of liquid injection pipe and vacuum tube is installed on the battery by lower seal, start vacuum pump then, earlier, open the ELECTROMAGNETIC VACUUM rotary valve again, utilize in the battery negative pressure with the disposable injection battery of electrolyte by topping-up pump with after being evacuated in the battery.
