When the circular lithium cell of new energy automobile need be annotated liquid operation when making the workman, can use this kind to annotate liquid equipment, at first the lithium cell of waiting to annotate liquid is put rear side on transmission device 2, start transmission device 2 afterwards, control transmission device 2 and drive the lithium cell and convey forward and close transmission device 2 behind the mechanism 3 below of pushing down, the lithium cell cooperates with mechanism 3 of pushing down, mechanism 3 cooperates with annotating liquid mechanism 4 of pushing down, make the electrolyte in annotating liquid mechanism 4 pour into the lithium cell into through mechanism 3 of pushing down, accomplish and open transmission device 2 once more after annotating the liquid, the lithium cell continues conveying forward, make things convenient for people to unload, close transmission device 2 at last.

The manufacturing worker feeds the lithium cell of liquid to transport belt 23 rear side to waiting to annotate, start servo motor 26 after that, servo motor 26 output shaft drives pivot 21 through second belt pulley 24 and flat belt 25, first belt pulley 22 and transport belt 23 rotate, thereby the realization will wait to annotate the effect of liquid lithium cell forward conveying to pushing down mechanism 3 below, close servo motor 26 this moment and annotate liquid, it finishes the back and starts servo motor 26 again to annotate liquid, make the lithium cell that annotates liquid and accomplish convey forward and unload, and the next lithium cell of annotating liquid conveys forward to pushing down mechanism 3 below simultaneously, so repeatedly can realize the automatic material of passing of lithium cell and the effect of conveniently unloading.

When the lithium battery is conveyed to the position below the shunt pressing plate 33, the lithium battery is contacted with the pressing rod 35, so that the pressing rod 35 drives the ejector rod 39 and the first sliding rod 37 to slide outwards, the second spring 36 is stretched, the third spring 38 is compressed, the pressing rod 35 is matched with the first wedge-shaped block 34, the telescopic rod 31 and the first spring 32 in the stretching state are reset to drive the shunt pressing plate 33 and the first wedge-shaped block 34 to move downwards, the shunt pressing plate 33 drives the shunt needle tube on the shunt pressing plate to be downwards inserted into a liquid inlet tube corresponding to the lithium battery below, at the moment, the liquid injection mechanism 4 is opened, electrolyte in the liquid injection mechanism 4 is injected into the lithium battery in a shunt mode through the needle tube on the shunt pressing plate 33, the effect of pressing liquid injection is achieved, after the lithium battery is injected, the lithium battery is continuously conveyed forwards and is not contacted with the pressing rod 35 any more, the second spring 36 and the, the push rod 39 makes the first wedge block 34 and the shunt pressure plate 33 move upwards, the telescopic rod 31 and the first spring 32 are stretched, and at the moment, the liquid injection mechanism 4 is closed, and liquid injection is stopped.

The reposition of redundant personnel clamp plate 33 reciprocates and drives liquid storage pot 41, first hose 42, first fixed block 43, liquid baffle 45, second slide bar 46 and fourth spring 47 whole reciprocate, when liquid baffle 45 moves down, second wedge 44 and the cooperation of liquid baffle 45 make liquid baffle 45 and second slide bar 46 outwards slide when moving down, fourth spring 47 is stretched, the opening on liquid baffle 45 at this moment corresponds with the export on the first hose 42, electrolyte in the liquid storage pot 41 flows to reposition of redundant personnel clamp plate 33 through first hose 42, realize dividing the effect of flowing liquid, when liquid baffle 45 moves up, the opening on liquid baffle 45 does not correspond with the export on the first hose 42, the electrolyte export is stopped up, thereby stop annotating the liquid.

The manufacturing worker puts into material frame 51 with a plurality of lithium cell stacks of treating annotating liquid, the lithium cell of bottom falls on striker plate 52, when ejector pin 39 outwards moves, ejector pin 39 drives connecting rod 53 outwards movement, thereby drive striker plate 52 along the outside slip of dead lever 54, fifth spring 55 is stretched, the lithium cell descends in proper order, the lithium cell of bottom falls on transportation belt 23, when ejector pin 39 inwards moves, fifth spring 55 resets and drives striker plate 52 and connecting rod 53 inwards move, striker plate 52 blocks the remaining lithium cell in top, so realize the effect of lithium cell automatic feeding.

In order to avoid the possible adverse effect of chemical gas generated during the liquid injection of the lithium battery on a human body, the chemical gas needs to be treated, the cylinder 64 is started, the cylinder 64 reciprocates back and forth, when the cylinder 64 extends to drive the connecting block 65 and the piston rod 63 to move forwards, the chemical gas is pumped into the piston cylinder 61 in a single direction through the air pumping pipe 62, when the cylinder 64 shortens, the gas in the piston cylinder 61 is pushed out through a small hole formed in the outer side of the piston cylinder 61, people uniformly collect and filter the pushed gas, and the air pumping can be stopped by closing the cylinder 64.

The gas in the piston cylinder 61 is pushed into the carbon containing cylinder 73 through the gas inlet pipe 75 and the second fixing block 76, part of the gas enters the carbon containing cylinder 73 through the mixing box 71, the second hose 77 and the connecting pipe 72, the activated carbon in the carbon containing cylinder 73 adsorbs and filters the gas, after the gas is filtered, the sliding plate 74 is opened, the filtered gas is discharged into the air, and then the sliding plate 74 is closed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
