Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clear, complete description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, belongs to the protection scope of the utility model.

In the description of the utility model, it is to be understood that "front", "rear" in term, " vertical ", "left", "right", The orientation or positional relationship of the instructions such as "upper", "lower" is to be based on the orientation or positional relationship shown in the drawings, merely for convenience to retouch It states the utility model and simplifies description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with Specific orientation construction and operation, therefore should not be understood as limiting the present invention.

As shown in Figure 1 to Figure 2, a kind of battery liquid-filling device, including pedestal 2, the fixed frame 1 above pedestal 2, fluid injection Needle 11, vacuum device and fixation kit 3, battery liquid-filling, which is divided into three steps, to carry out, i.e., the fixation of battery to be injected, wait infuse Solution battery vacuumizes and fluid injection.

The fixation of battery to be injected: the first push plate 313 battery to be injected being placed in the concave plate 319 of fixation kit 3 Position between third push plate 310 starts rotating electric machine 304 at that time and feed screw nut 303 is driven to rotate, then drives screw rod 308 movements, with the advance of screw rod 308, the second push plate 302 set on 308 end of screw rod pushes third push plate 310 towards concave 319 inner part of plate is mobile, as the mobile intercell that can treat of third push plate 310 generates a pressure, at that time, battery to be injected The first push plate 313 can be squeezed, the first push plate 313 is caused to move back, until the first limit plate 320 of 316 end of first connecting rod setting supports Firmly until the side plate of L-type pedestal 314, the extruding force of intercell formation is treated in the first push plate 313 with third push plate 310, make to Intercell is firmly fixed on this.

Vacuumize: the operation vacuumized after battery to be injected is fixed installs an infrared emission in support platform 5 Device 7 is equipped with one first infrared receiving device 17 and one second infrared receiving device 18 on movable rod 19, works as infrared emission When device 7 is aligned with the second infrared receiving device 18, the inductor in the second infrared receiving device 18 is transferred signals to At stepper motor 16,19 stop motion of movable rod, simultaneously cylinder 3 equally receives signal, and piston rod 4 stretches out, support Platform 5, which rises to, facilitates vacuum device to treat intercell progress vacuum pumping；The vacuum device includes being fixed on Aspiration pump 8 on movable rod 19, the pump-line 10 being connect with the aspiration pump 8 and the pressure set on 8 avris of aspiration pump Meter 9, aspiration pump 8 are extracted out the air of inside battery to be injected by pump-line 10 after starting, and pressure gauge 9 treats intercell Interior pressure measures, according to the atmospheric pressure value of the big minor adjustment aspiration pump 8 of pressure.

Fluid injection: after battery vacuum-pumping to be injected, the movement of next step, i.e. fluid injection are carried out.16 control activity of stepper motor Connecting rod 19 is mobile, until infrared launcher 7 is aligned with the first infrared receiving device 17, stepper motor receives the first infrared receiver The signal stop motion that device 17 occurs, while topping-up pump 14 takes out the electrolyte 12 in liquid storing barrel 13 along liquid injecting pipeline 15 Out, it is filled into inside injection needle 11, the liquid injection port that injection needle 11 passes through battery to be injected treats intercell and carries out fluid injection.

In addition, first push plate 313 is equipped with the first rubber pad 312, the second rubber pad is fixed in third push plate 310 311, prevent the first push plate 313 and 310 quality of third push plate damage battery really up to the mark；The first bullet is arranged on first connecting rod 316 Spring 318, on the one hand plays the role of buffering, on the other hand limits the distance of the retrogressing of first connecting rod 316；Set on second connecting rod Second spring 309 on 317 equally plays the role of buffering, and the second push plate 302 is when pushing third push plate 311 to advance, and second The third limit plate 305 of 317 end of connecting rod setting squeezes second spring 309 and slowly moves ahead, since the elastic force of second spring 309 is made With forward speed is limited, effect of inertia is avoided to damage battery.

In addition, the second limit plate 307 of 308 end of screw rod setting is movable forward in sliding slot 306 with screw rod 308, when second Limit plate 307 contacts on 319 munnion of concave plate that rotating electric machine 304 stops operating, can be big according to the size of practical battery to be injected The length of small setting screw rod 308, prevents excessive extruding force from treating damage caused by intercell.

In addition, the topping-up pump 14 is electric precise topping-up pump.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
