Description
Technical field
The utility model relates to a kind of lithium ion battery fluid injection shower nozzle.
Background technology
At present, in the lithium ion battery assembling process, the general method that adopts of fluid injection is that a conduit connects a liquid injection hole, inject the electrolyte into electric in-core portion by pressure control, this mode is less applicable to size, the battery that the electrolyte demand is low, but for larger-size electrokinetic cell, the military products battery, because the big capacity height of volume, require the electrolyte of injection also much more than baby battery, adopt single liquid injection hole fluid injection speed slow, efficient is low, and electrolyte hoards at inside battery after injecting along single position, needs very long infiltrating time, influences the fabrication cycle of battery.
The utility model content
The purpose of this utility model is to provide a kind of lithium ion battery fluid injection shower nozzle, is intended to solve that present macrocell fluid injection speed is slow, efficient is low, the technical problem of time and effort consuming.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of lithium ion battery fluid injection shower nozzle comprises a fluid injection nozzle body, is provided with many liquid injection pipes in described fluid injection nozzle body.
Described fluid injection nozzle body has a plurality of fixing threaded holes that run through, the upper end of described every liquid injection pipe has corresponding screw, and described every liquid injection pipe is installed on described running through in the fixing threaded hole and disassembled being installed on the described fluid injection nozzle body by the attaching nut.
Be provided with one for the screw that is connected with automatic fluid injection equipment in described fluid injection nozzle body.
Described liquid injection pipe is 8.
Compare with original technology, the beneficial effects of the utility model are: inject in the time of by many liquid injection pipes, thereby can realize the injection of electrolyte fast, efficiently, uniformly, significantly promote production efficiency.
Description of drawings
Fig. 1 provides a kind of perspective view of lithium ion battery fluid injection shower nozzle for the utility model;
Fig. 2 is the end view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 provides the structural representation of another kind of lithium ion battery fluid injection shower nozzle for the utility model;
Fig. 5 provides the structural representation of another lithium ion battery fluid injection shower nozzle for the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in Fig. 1 ~ 3, a kind of lithium ion battery fluid injection shower nozzle comprises a straight tube shape fluid injection nozzle body 1, is provided with many liquid injection pipes 2 in described straight tube shape fluid injection nozzle body 1.This kind lithium ion battery fluid injection shower nozzle can satisfy the fluid injection requirement of flexible packing lithium ion battery.
Further, described straight tube shape fluid injection nozzle body 1 has a plurality of fixing threaded holes 5 that run through, the upper end of described every liquid injection pipe 2 has corresponding screw, and described every liquid injection pipe 2 is installed on described run through in the fixing threaded hole 5 and disassembled being installed on the described fluid injection nozzle body 1 by attaching nut 3.The detachability of many liquid injection pipes makes things convenient for the replacing of liquid injection pipe and installs and uses
Further, be provided with one for the screw 4 that is connected with automatic fluid injection equipment in described straight tube shape fluid injection nozzle body 1.
More excellent, described liquid injection pipe 2 is 8.
Referring to shown in Figure 4, a kind of lithium ion battery fluid injection shower nozzle, the structure of this lithium ion battery fluid injection shower nozzle except the structure of fluid injection nozzle body with previous embodiment is different, other structure is all identical, referring to shown in Figure 4, the fluid injection nozzle body of this lithium ion battery fluid injection shower nozzle is a discoid fluid injection sprayer body 6, and this kind lithium ion battery fluid injection shower nozzle can satisfy the fluid injection requirement of circular appearance battery.Referring to shown in Figure 5, the figure shows the structure of the another lithium ion battery fluid injection shower nozzle that the utility model embodiment provides, different with aforesaid lithium ion battery fluid injection shower nozzle is, its fluid injection nozzle body is a square body fluid injection sprayer body 7, the fluid injection requirement of this kind lithium ion battery fluid injection shower nozzle square appearance battery.
Be assembled into example with 20Ah flexible packaging power battery, adopt common fluid injection shower nozzle and the straight type fluid injection shower nozzle of flexible package macrocell that is applicable to described in the utility model to carry out fluid injection respectively, the fluid injection coefficient is 4.2g/Ah, and following table 1 is 20 battery liquid-filling correction datas:
Table 1
As can be seen, two kinds of fluid injection shower nozzle reservoir quantity difference are little, but adopt common shower nozzle fluid injection, finish an electric battery liquid-filling and need hydrojet 7 times, each hydrojet needs the time interval, finishes the primary cell fluid injection and takes 65 seconds altogether, adopt new type nozzle only to need 1 time, 5s can finish.
Be example with this model battery, use 1 day main liquid equipment of common fluid injection shower nozzle can finish 150 battery liquid-fillings aborning, if adopt novel fluid injection shower nozzle, can finish 900 in one day, efficient can promote Secondly, adopt this shower nozzle electrolyte to inject along each layer of utmost point group pole piece uniformly, to a certain degree can reduce infiltrating time, shorten the battery fabrication cycle.
When needs are used for the differently sized batteries fluid injection, only need suitably increase and decrease shower nozzle quantity, can achieve the goal.When being required to be rectangular cell, circular batteries fluid injection, correspondingly choose with it supporting fluid injection shower nozzle, can realize the effect that above-mentioned straight type shower nozzle reaches on flexible-packed battery.
Thereby, to compare with original technology, the utility model injects by many liquid injection pipes the time, thereby can realize the injection of electrolyte fast, efficiently, uniformly, significantly promotes production efficiency.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
