The electrolyte filling head also comprises a sealing head, wherein the sealing head is a hollow cone of which the bottom surface faces the base. The electrolyte filling head can be used for realizing the electrolyte filling and packaging of the battery on one station.
Description
Technical field
The utility model relates to a kind of battery electrolytic solution filling head, belongs to battery manufacture field.
Background technology
In traditional battery electrolyte filling process, just by a fluid injection syringe needle directly to the enter filling of electrolyte of battery, whole process is easy to make battery entrained air or dust, and comparatively advanced suction type fluid injection, whole equipment is comparatively complicated, technological requirement is also higher, be not suitable for small lot, produce cheaply, when the battery of the electrolyte of simultaneously having annotated leaves work top, also can there is secondary pollution in the electrolyte of its inside, sneak into the materials such as dust in workshop.
Utility model content
The technical problems to be solved in the utility model is: overcome fluid injection in prior art and easily sneak into the technical problem of hole gas and dust, a kind of good airproof performance is provided, can realize the one step completed novel filling head of fluid injection encapsulation.
The utility model solves the technical scheme that its technical problem adopts:
A kind of battery electrolytic solution filling head, described filling head comprises base and pushing block, and the middle part of described base is fixed with fluid injection pin, and the central part of described base is also provided with liquid injection pipe connecting hole, and described liquid injection pipe connecting hole is communicated with fluid injection pin;
Described pushing block is socketed on fluid injection pin, described pushing block annular array arrangement on the end of one end of base has some piston rods, position at the corresponding piston rod of described base is provided with some piston holes, described piston rod is inserted in piston hole, on one end of fluid injection pin, be provided with at least one force pipe connecting hole dorsad at base, described force pipe connecting hole is communicated with each piston hole, and described pushing block is provided with a seal head on one end of piston rod dorsad and promotes end face;
Described filling head also comprises seal head, and described seal head is hollow cone body, and wherein the bottom surface of cone is towards base.
As further innovation of the present utility model, at the axis top of described seal head to being provided with some straight-line grooves that are positioned on seal head inwall between middle part.
The beneficial effects of the utility model are as follows:
1, the utility model is by integrating mechanism for filling liquid and seal head delivery device, seal head not only can be in fluid injection process, realize the sealing of whole battery cavities, simultaneously after filling, pass through pushing mechanism, seal head is pressed in battery liquid-filling hole, can realizes electrolyte filling and the encapsulation of a station battery.
2, the utility model arranges straight-line groove on seal head, can improve sealing and the compressibility of seal head, ensures that seal head is pressed into seal and the stability behind battery liquid-filling hole.
?
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the generalized section of seal head.
In figure: 1, base; 2, pushing block; 3, force pipe connecting hole; 4, piston rod; 5, fluid injection pin; 6 seal heads.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the utility model is the head for injecting electrolytic solution that a kind of battery is used, and the utility model, than traditional mechanism for filling liquid, has added the top-pressure mechanism of a seal head on fluid injection pin, and integrate, realized battery liquid-filling and the sealing of a station;
The utility model mainly comprises base 1 and pushing block 2, be vertically installed with a fluid injection pin 5 at the central part of base 1, fluid injection pin 5 is communicated with the liquid injection pipe connecting hole that is arranged on base 1 bottom, while is at the periphery of fluid injection pin 5, some piston holes are processed, pushing block 2 leads by fluid injection pin 5, be socketed on fluid injection pin 5, be provided with some piston rods 4 at pushing block 2 towards the corresponding piston hole in one end of base 1, piston rod 4 is inserted in piston hole, also be provided with two force pipe connecting holes 3 that are communicated with piston hole in the bottom of base 1, by Bonding pressure source on force pipe connecting hole 3, piston rod is pushed,
Be provided with a promotion end face corresponding with seal head 6 bottom surfaces in one end of base dorsad at pushing block 2, the conical block rubber that seal head 6 is hollow, in fluid injection, mobile filling head is to battery liquid-filling hole, and the space between fluid injection pin and liquid injection hole has been filled up at seal head 6 tips now, then after fluid injection completes, pushing block 2 moves, seal head 6 is pressed in liquid injection hole, realizes sealing, just can not there is not leakage or pollution in battery like this in the process shifting.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
