[0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. Electrolyte is the medium used in chemical batteries, electrolytic capacitors, etc., which provides ions for their normal operation. There are many advantages to using electrolyte as the cathode. First, the contact area between the liquid and the medium is large, which helps to increase the capacitance. Secondly, electrolytic capacitors made with electrolyte can withstand high temperatures, so they can pass wave soldering, and they are also relatively strong in pressure resistance.

[0003] During the processing of lithium batteries, electrolyte needs to be added to the inside of the battery with electrodes. However, the amount of electrolyte added is quantitative. If it is added manually, there is a possibility of over- or under-filling, which will make the battery unqualified. In addition, manual filling is slow and the work efficiency is low.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lithium battery processing and electrolyte filling device, comprising: a bracket, on which a liquid inlet mechanism, a quantitative mechanism, a liquid discharge pipe and a pushing part are arranged, and the electrolyte introduced by the liquid inlet mechanism is quantitatively measured by the quantitative mechanism, and the electrolyte is accurately filled in cooperation with the pushing part and the liquid discharge pipe.

[0006] Furthermore, the liquid inlet mechanism comprises an electrolyte box, the electrolyte box is fixedly mounted on the top of the bracket, and a liquid inlet pipe is installed below the electrolyte box.

[0007] Furthermore, the quantitative mechanism comprises a weighing cylinder, which is slidably arranged in the bracket. Two quantitative tanks are arranged in the weighing cylinder, and the quantitative tanks are connected to liquid guide nozzles through springs.

[0008] Furthermore, a plunger is arranged in the liquid guiding nozzle, the top end of the plunger is slidably arranged in the liquid outlet of the quantitative tank, and a liquid passing hole is provided at the lower end of the plunger.

[0009] Furthermore, two drainage holes are provided in the bracket, the drainage pipeline includes a drainage main pipe and a drainage auxiliary pipe, and the two drainage holes are respectively connected to the drainage main pipe and the drainage auxiliary pipe.

[0010] Furthermore, a weighing part is arranged between the two drainage holes.

[0011] Furthermore, one side of the pushing portion is fixedly connected to the weighing cylinder, and the pushing portion drives the weighing cylinder to perform reciprocating motion.

[0012] In the above technical solution, the utility model provides a lithium battery processing electrolyte filling device with the beneficial effects:

[0013] The utility model introduces electrolyte into the quantitative mechanism through the liquid inlet mechanism, accurately weighs and quantifies the electrolyte through the quantitative mechanism, and cooperates with the pushing part and the liquid discharge pipe to realize accurate filling, that is, the electrolyte in the electrolyte box is introduced into the quantitative tank through the liquid inlet pipe, and the weighing part weighs the increasing electrolyte. When the weight of the weighing cylinder as a whole reaches the set value, the pushing part pushes the weighing cylinder to make the quantitative tank connected with one of the liquid discharge holes, discharges the electrolyte and fills it into the battery. At this time, the other quantitative tank slides under the liquid inlet pipe, and the liquid inlet pipe continues the next round of filling. The pushing part continuously pushes the quantitative tank that meets the conditions to the top of the liquid discharge hole to discharge the electrolyte and fill it into the battery, thereby realizing accurate and fast electrolyte filling of the battery, greatly improving efficiency.

[0023] Please refer to 1-3, a lithium battery processing and electrolyte filling device, including: a bracket 1, on which a liquid inlet mechanism, a quantitative mechanism, a liquid discharge pipe and a pushing part 5 are arranged. The electrolyte introduced by the liquid inlet mechanism is quantitatively measured by the quantitative mechanism, and is precisely filled in cooperation with the pushing part 5 and the liquid discharge pipe.

[0024] Specifically, the utility model introduces the electrolyte into the quantitative mechanism through the liquid inlet mechanism, accurately weighs and quantifies the electrolyte through the quantitative mechanism, and cooperates with the pushing part 5 and the discharge pipe to achieve precise filling, that is, the electrolyte in the electrolyte box 2 is introduced into the quantitative tank 10 through the liquid inlet pipe 3, and the weighing part 8 weighs the increasing electrolyte. When the overall weight of the weighing cylinder 7 reaches the set value, the pushing part 5 pushes the weighing cylinder 7 to make the quantitative tank 10 connected with one of the discharge holes 4, and the electrolyte is discharged and filled into the battery. At this time, the other quantitative tank 10 slides under the liquid inlet pipe 3, and the liquid inlet pipe 3 continues the next round of filling. The pushing part 5 continuously pushes the quantitative tank 10 that meets the conditions to the top of the discharge hole 4 to discharge the electrolyte and fill it into the battery, thereby realizing accurate and rapid electrolyte filling of the battery, greatly improving efficiency.

[0025] In another embodiment of the present invention, reference Figures 1 to 3, a lithium battery processing electrolyte filling device, comprising: a bracket 1, the bracket 1 is provided with a liquid inlet mechanism, a quantitative mechanism, a liquid discharge pipe and a push part 5, the electrolyte introduced by the liquid inlet mechanism is quantitatively measured by the quantitative mechanism, and the electrolyte is accurately filled in cooperation with the push part 5 and the liquid discharge pipe, the liquid inlet mechanism comprises an electrolyte tank 2, the electrolyte tank 2 is fixedly installed on the top of the bracket 1, and a liquid inlet pipe 3 is installed below the electrolyte tank 2, the quantitative mechanism comprises a weighing cylinder 7, the weighing cylinder 7 is slidably arranged in the bracket 1, and two quantitative tanks 10 are arranged in the weighing cylinder 7, the quantitative tank 10 is fixedly connected to the weighing cylinder 7, the quantitative tank 10 is connected to a liquid guide nozzle 9 through a spring 11, the spring 11 is sleeved outside the quantitative tank 10, and one end is fixed The bracket 1 is fixedly connected to the quantitative tank 10, and the other end is fixedly connected to the liquid guide nozzle 9. A plunger 12 is arranged in the liquid guide nozzle 9. The top end of the plunger 12 is slidably arranged in the liquid outlet of the quantitative tank 10, and a liquid hole 121 is arranged at the lower end of the plunger 12. Two drainage holes 4 are arranged in the bracket 1. The drainage holes 4 are located directly below the weighing cylinder 7. The drainage pipeline includes a drainage main pipe 61 and a drainage auxiliary pipe 62. The two drainage holes 4 are respectively connected to the drainage main pipe 61 and the drainage auxiliary pipe 62. A weighing part 8 is arranged in the middle of the two drainage holes 4. One side of the pushing part 5 is fixedly connected to the weighing cylinder 7. The pushing part 5 drives the weighing cylinder 7 to do reciprocating motion, and the electrolyte is introduced into one of the quantitative tanks 10 through the liquid inlet pipe 3. The weighing part 8 weighs the continuously added electrolyte. When the total weight of the weighing cylinder 7 reaches the specified index, the pushing part 5 pushes the weighing cylinder 7 to slide, so that the quantitative tank 10 is connected with a drainage hole 4. At this time, the lower end of the plunger 12 loses contact, and the liquid guide nozzle 9 slides downward under the elastic force of the spring 11. The upper end of the plunger 12 no longer blocks the liquid outlet of the quantitative tank 10. The electrolyte in the quantitative tank 10 will be discharged into the battery to be filled through the drainage auxiliary pipe 62.

The liquid inlet pipe 3 also has a self-locking device, which includes a liquid guide nozzle 9, a quantitative tank 10, a spring 11, and a plunger 12. During the sliding process, when the liquid inlet pipe 3 passes between the two quantitative tanks 10, the liquid guide nozzle 9 is abutted, thereby overcoming the elastic force of the spring 11 and sliding upward, and the plunger 12 blocks the discharge port of the quantitative tank 10, and the electrolyte will not flow out. After the liquid inlet pipe 3 enters the other quantitative tank 10, the liquid guide nozzle 9 slides downward under the elastic force of the spring 11, so that the liquid inlet pipe 3 and the quantitative tank 10 are connected. In the above device, the size of the outlet of the quantitative tank 10, the outlet of the liquid guide nozzle 9 and the discharge pipe are all larger than the outlet size of the liquid inlet pipe 3, so when the weight of the weighing cylinder 7 reaches the maximum value, the electrolyte in one of the quantitative tanks 10 has been drained, ensuring the accuracy of the electrolyte quantification.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
