Description
Technical field
The utility model relates to lithium ion battery fluid injection machine field, more particularly, relates to the applicator roller and the last liquid systems of lithium ion battery fluid injection machine.
Background technology
Generally, lithium ion battery fluid injection machine uses semi-automatic and full-automatic fluid injection mode, realize the fluid injection of battery, but the last liquid systems of these fluid injection machines is imperfection all, exist when annotating many batteries simultaneously, do not point out and then cause defectives such as not having operation after reservoir quantity instability and electrolyte storage device electrolyte use up, be difficult to improve the efficient of automatic filling machine and the stability of reservoir quantity.The last liquid systems of existing fluid injection machine mainly contains two kinds: 1) be made of electrolyte tank, fluid reservoir, last fluid valve, topping-up pump, distributor and fluid injection syringe needle etc.; 2) constitute by pressure control device, electrolyte tank, fluid reservoir, topping-up pump, distributor and fluid injection syringe needle etc.First kind of structure needs to open liquid on the valve by hand, can not realize going up automatically liquid; Second kind of structure is by fill the nitrogen of certain pressure intensity to electrolyte tank, and by liquid on the nitrogen pressure, but this structure is not controlled the pressure of nitrogen, can not in time find after electrolyte uses up, and can cause some battery not have fluid injection.These two kinds of structures all can not realize the automatic control of electrolyte, and can not solve the assignment problem of electrolyte, the main liquid measure less stable of electrolyte.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of automatic applicator roller of lithium ion battery fluid injection machine that can guarantee that reservoir quantity is stable is provided.
The automatic applicator roller of the utility model lithium ion battery fluid injection machine, be achieved by following technical proposals, the air delivering pipeline that micromanometer is set is connected with electrolyte tank by the fast interface of gas circuit, infusion pipeline is connected with electrolyte tank by the fast interface in liquid road, it is characterized in that, the described infusion pipeline other end connects fluid reservoir, and the fluid reservoir bottom is provided with lower valve, and the fluid reservoir top is provided with valve; The U type connecting tube that the setting of fluid reservoir sidewall is communicated with the fluid reservoir sidewall, U type connecting tube middle part is provided with liquid level sensor; The fluid reservoir top connects priming device, and described priming device is made of the fluid injection pipeline that connects topping-up pump and filling head successively, and an end of fluid injection pipeline connects the fluid reservoir top.
Fluid reservoir described in the utility model top connects at least two priming devices.Connecting tube of described U type and fluid reservoir parallel sidewalls partly are the transparent body.
The utlity model has following beneficial effect:
1) nitrogen pressure of coming computing system to provide by the liquid level difference of calculating from the electrolyte fluid reservoir to topping-up pump, accurately control the pressure of nitrogen by the micromanometer of Kpa level, utilize the conductibility principle of liquid pressure to realize the automatic supply of electrolyte again, and how much electrolyte, system's how much electrolyte of supply have been realized using.
2) be communicated with the electrolyte of electrolyte tank by the transparent pipeline that law of connected vessels is set in the fluid reservoir position, and the method for liquid level inductive pick-up is set in transparent position, realize equipment alarm after the electrolyte in the electrolyte tank uses up and out of service, solved in the automatic assembly line village also system and can not detect the difficult problem that electrolyte also is, realized the mistake proofing of equipment.
3) this device can be applied to adopt the fluid injection machine and the relevant liquid injection system of the circle of quantitative fluid injection technology, square, plastic flexible package and multiple lithium ion batteries such as polymer battery.Common applicator roller can not realize going up automatically functions such as liquid or blade face warning, need manually to go up the liquid level of liquid or artificial visual electrolyte by the folding of valve, can not realize mistake proofing on the one hand, avoid occurring not having the loss that causes of operation continuously of equipment under the situation of electrolyte, on the other hand, the artificial liquid of going up also needs the operator to pay close attention to the operating position of electrolyte constantly, can't adopt in automatic assembly line or automatic fluid injection system.And adopt this liquid systems of going up automatically, can thoroughly address the above problem.
4) this apparatus structure is simple, cost is low, easy realization, can guarantee the stability of liquid injection system, can the simple mechanism combination the automatic upward liquid of liquid injection system and the automatic warning function that electrolyte is finished using have been realized, can apply to preferably on the automatic equipment, realize the intellectuality of liquid systems on the equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the air delivering pipeline 2 that micromanometer 3 is set is connected with electrolyte tank 9 by the fast interface 5 of gas circuit, and infusion pipeline 1 is connected with electrolyte tank 9 by the fast interface 7 in liquid road, and the infusion pipeline other end connects fluid reservoir, the fluid reservoir bottom is provided with lower valve 10, and the fluid reservoir top is provided with valve 15; The U type connecting tube 12 that the setting of fluid reservoir sidewall is communicated with the fluid reservoir sidewall, U type connecting tube middle part is provided with liquid level sensor 13; The fluid reservoir top connects priming device, and described priming device is made of the fluid injection pipeline 18 that connects topping-up pump 17 and filling head 16 successively, and an end of fluid injection pipeline connects the fluid reservoir top.Use at the same time under the situation of a plurality of topping-up pumps (Haibar pump) fluid injection, can use the priming device of many covers, this example adopts the device of 3 Haibar pumps.
The utility model is the micromanometer of (0-0.2) Mpa by using SMC AR-2000 type range, the pressure of control electrolyte bucket gas port input, because the accurate pressure of control input end, on the one hand, can make electrolyte go up fluid reservoir automatically, enter into the interface of topping-up pump (Haibar pump) again by fluid reservoir, on the other hand, because the pressure of pressure is little, can the precision of Haibar pump not impacted, this has also just solved the liquid problem that goes up automatically of electrolyte.Secondly, liquid level induction system by the tank connected law of connected vessels of liquid storage, can respond to the liquid level of electrolyte, when electrolyte level was lower than sensing station, illustrating did not have electrolyte yet in the electrolysis bucket, equipment alarm, out of service, remind the workman to change the electrolyte bucket, the connection type that the electrolyte bucket uses is inserted soon, plug is convenient, and the electrolysis bucket is easy to change.Once more, this installs all direct fluids in the fluid reservoir of all topping-up pumps (Haibar pump), has so also solved by same electrolysis tube fluid, divides the electrolyte inequality to cause the reservoir quantity problem of unstable by distributor again.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection range of the present utility model.
