Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
Fig. 1 ~ Fig. 6 is please referred to, the embodiment of the present invention includes:
It is a kind of can simultaneously when vacuumizing fluid injection structure, including the automatic vacuum mechanism for filling liquid being installed on rack backplate.
Wherein, the back side of rack backplate 1 is equipped with the sliding rail 11 being arranged along the vertical direction, installs and is provided with cooperation sliding rail 11 on grillage 2
Guide groove.Rack backplate 1 and installation grillage 2 are separately fixed on the piston rod and cylinder body of third cylinder 3, therefore pass through third gas
Cylinder 3 realizes rack backplate 1 and installs the vertical sliding between grillage 2.
Automatic vacuum mechanism for filling liquid includes two fluid injection cup groups being set side by side, and each fluid injection cup group includes being fixed on machine
On frame backplate: upper cup body 4, lower cup body 5.Sealing bar 21 is provided in upper cup body 4, the upper end of sealing bar 21 is connected to the first gas
Cylinder 6, the first cylinder 6 push 21 vertical displacement of sealing bar.Therefore, sealing bar 21 can be floated up and down in the axial direction to realize upper cup body
The on-off of outlet.Upper cup body outlet float be cased with one stretched out with Pneumatic pressure power after dock lower cup body buffering mouth 7, buffer mouth
7 are installed by one piece of fixed plate 8, and the second cylinder 9 that fixed plate 8 is stretched vertically by one pushes.Specific structure are as follows: in rack
One bracket 10 is installed, bracket 10 is set between upper cup body 4 and lower cup body 5 on backplate.Cooperated on bracket 10 by guide sleeve 12
There is the guide rod 13 of vertical sliding, 13 lower end of guide rod passes through the installation buffering mouth 7 of fixed plate 8.Second cylinder 9 is fixed over the mount 10,
The second cylinder 9 pushes and pulls fixed plate 8 vertically simultaneously.
It further include one and the check valve 14 that connect of buffering mouth 7 on lower cup body 5, buffering that mouth 7 docks with check valve 14 can be with
Realize the connection of two ontologies.The siphon bend component of a connection lower cup body outlet, lower cup body outlet are provided in lower cup body 5
Upper setting liquid injecting mouth 15.The siphon bend includes: the company that the suction side 16, one for being higher than lower cup body outlet is higher than suction side
Logical portion, can be injected the electrolyte into battery using siphon principle while control raffinate overflow.Siphon bend component includes one
Siphon bend also may include four siphon bends.If siphon bend group selects a siphon bend, i.e. 16 He of suction side
One outlet side 17, therefore the siphon bend is in the arrangement of falling U-shaped.It is then four suction sides 16 according to four siphon bends, one
A outlet side 17 is docked between suction side 16 and outlet side 17 by an interconnecting part.Using 4 pipe structures, rainbow is improved
The reaction speed of suction accelerates fluid injection efficiency, and makes to reduce residual, more advantage in cup.
The inner bottom surface of lower cup body offers the recessed of cooperation suction side in the conical surface shape 18 turned round on internal bottom surface
Fall into area 19, the bottom surface holding flow clearance of suction side and depressed area 19, the circulation fluid injection that such electrolyte can continue to battery
It is interior, while fluid injection flow velocity can also be stablized.
It is additionally provided on rack backplate 1 and arranges the pneumoelectric junction box 20 set for route and tracheae.
Based on above structure, the working principle of the invention:
(1) entire evacuation priming device is fixed on vertically on installation grillage 1；
(2) evacuation priming device is whole pushes under the effect of third cylinder 3；
(3) liquid injecting mouth 15 of lower cup body 5 acts on battery, buffering mouth 7 be connected to two cup bodies, by the movement of sealing bar 21 come
It is connected to evacuated path or fluid injection path, after fluid injection and is stood；
(4) then third cylinder 3 lifts, and meets raffinate mechanism and starts to connect raffinate and clean.
In conclusion automatic vacuum mechanism for filling liquid push after, before formal fluid injection to battery vacuum-pumping or fluid injection after
It vacuumizes or can carry out simultaneously；It, can be after the completion of fluid injection due to the syphon structure in automatic vacuum mechanism for filling liquid lower cup body
Ascent stage guarantees that not infused liquid in cup will not flow out from rim of a cup, keeps lower section cleaning.Since cup body is that separate pressing plate is matched entirely
Setting can take out respectively, in batches without influencing other stations, accelerate maintenance efficiency when failure, all cup bodies can individually take out
Maintenance, installing and dismounting are easy.Raffinate function is connect since automatic vacuum mechanism for filling liquid lower cup body special construction simplifies, is reduced
Cost, improves utilization rate of equipment and installations, accelerates the fluid injection deadline.Installing overpressure buffer when cylinder declines additional can avoid weighing wounded
Battery improves battery yield, and avoids electrolytic corrosion equipment, reduces maintenance cost.
