Description

Technical Field

[0001] This utility model relates to the field of electrolyte filling technology, and in particular to a sodium-ion battery electrolyte filling mechanism. Background Technology

[0002] Sodium-ion batteries are rechargeable batteries that rely primarily on the movement of sodium ions between the positive and negative electrodes to function, similar to lithium-ion batteries. The electrolyte is an important discharge material in sodium-ion batteries, and it needs to be filled during the manufacturing process.

[0003] In existing technologies, most methods involve using a filling mechanism to fill sodium-ion batteries with electrolyte. The sodium-ion battery is placed directly below the outlet tube for filling. Typically, an outlet head is installed at the bottom of the outlet tube by bolts or screws. While this installation method is secure, it makes it inconvenient to replace the outlet head if it becomes blocked or damaged, reducing the processing efficiency of sodium-ion batteries. Furthermore, the outlet tube and outlet head are usually at a fixed height, which cannot be adjusted, making it easy for electrolyte to splash out of the sodium-ion battery, resulting in waste.

A positioning block 13 is fixedly installed on the outer surface of each of the three liquid outlet pipes 10.

[0032] To facilitate the replacement of the dispensing head 11, the inner walls of the three dispensing heads 11 are provided with positioning grooves.

[0033] To adjust the height of the liquid outlet head 11, drive blocks 17 are fixedly installed at both ends of the liquid storage compartment 9. Two mounting brackets 18 are fixedly installed on the upper surface of the workbench 1. A servo motor 19 is fixedly installed on the lower surface of the workbench 1. A threaded rod 20 is fixedly installed at the output end of the servo motor 19. The threaded rod 20 passes through the lower surface of the workbench 1 and extends to the upper surface of the workbench 1. The top end of the threaded rod 20 is rotatably connected to the inner wall of the top end of one mounting bracket 18.

[0034] By configuring a workbench 1, a storage tank 2, an inlet pipe 3, a pump 4, a suction pipe 5, a through pipe 6, a valve 7, an extension pipe 8, a storage compartment 9, an outlet pipe 10, an outlet head 11, a connecting pipe 12, a positioning block 13, a fixing plate 14, a limit rod 15, a tension spring 16, a drive block 17, a mounting bracket 18, a servo motor 19, a threaded rod 20, a sliding rod 21, and a limit block 22, the device enables quick and convenient replacement of the outlet head 11. This improves the installation method of the outlet head 11 in existing devices, allowing for rapid replacement of the outlet head 11 when it becomes blocked or damaged, thus increasing the processing efficiency of sodium-ion batteries. Furthermore, the height of the outlet pipe 10 and the outlet head 11 can be adjusted to prevent electrolyte from splashing out of the sodium-ion battery and avoid waste.

[0035] The upper surface of the workbench 1 is provided with a fixing component, which includes a fixing block 23 and an electric telescopic rod 24. Both the fixing block 23 and the electric telescopic rod 24 are fixedly installed on the upper surface of the workbench 1. A pressure block 25 is fixedly installed at the output end of the electric telescopic rod 24. A slider 26 is fixedly installed on the lower surface of the pressure block 25. A sliding groove is opened on the upper surface of the workbench 1. The slider 26 is slidably connected to the inner wall of the sliding groove. Three placement slots 27 are opened on the side opposite to the fixing block 23 and the pressure block 25. Rubber buffer sheets 28 are fixedly installed on the inner walls of the six placement slots 27.

[0036] The sodium-ion battery is fixed by means of a fixed block 23, an electric telescopic rod 24, a pressure block 25, a slider 26, a placement groove 27, and a rubber buffer sheet 28. The sodium-ion battery is fixed by clamping it with the fixed block 23 and the pressure block 25, which improves the stability of the sodium-ion battery and prevents it from shifting or shaking during the electrolyte filling process. It also further prevents the electrolyte from splashing out of the sodium-ion battery.

[0037] Working principle: When filling the sodium-ion batteries with electrolyte using the filling mechanism, the electrolyte is first added to the storage tank 2 through the inlet pipe 3. Then, three sodium-ion batteries are placed on the upper surface of the workbench 1, ensuring that all three batteries are inside the placement slots 27 on the fixed block 23. Next, the electric telescopic rod 24 is activated, causing it to extend and push the pressure block 25 towards the fixed block 23. The slider 26 slides inside the groove. When the placement slots 27 on the fixed block 23 contact the sodium-ion batteries, The rubber buffer sheet 28 is tightly attached to the outer wall of the sodium-ion battery. Then, the electric telescopic rod 24 is controlled to stop extending. At this time, the three sodium-ion batteries are clamped and fixed by the fixing block 23 and the pressure block 25 through the placement groove 27. At this time, the three sodium-ion batteries are directly below the three liquid outlets 11. Then, the valve 7 is opened and the liquid pump 4 is started. The liquid pump 4 draws the electrolyte from the storage tank 2 through the liquid pumping pipe 5 and delivers it to the storage compartment 9 through the liquid passage pipe 6 and the extension pipe 8. Then, the electrolyte is filled into the sodium-ion battery through the liquid outlet pipe 10 and the liquid outlet 11.

[0038] When replacing the liquid outlet head 11, first pull the limiting rod 15 to stretch and deform the tension spring 16, and at the same time, let the limiting rod 15 slide out of the limiting hole to release the fixation of the liquid outlet head 11. Then pull the liquid outlet head 11 down so that the liquid outlet head 11 slides down on the outer surface of the liquid outlet pipe 10, the positioning block 13 slides inside the positioning groove, and the connecting pipe 12 slides to the outside of the liquid outlet pipe 10. When the liquid outlet head 11 is separated from the liquid outlet pipe 10, the connecting pipe 12 slides out from the inside of the liquid outlet pipe 10. Then take out the new liquid outlet head 11 and reverse the above operation to complete the replacement of the liquid outlet head 11.

[0039] When adjusting the height of the liquid outlet pipe 10 and the liquid outlet head 11, the servo motor 19 is started, causing the servo motor 19 to drive the threaded rod 20 to rotate. When the threaded rod 20 rotates, under the action of the driving block 17 and the sliding rod 21, the liquid storage cell 9 rises or falls, and at the same time, the extension tube 8 slides up or down inside the liquid passage pipe 6. The limiting block 22 slides inside the limiting groove. At the same time, the liquid storage cell 9 drives the liquid outlet pipe 10 and the liquid outlet head 11 to rise or fall. When the liquid outlet pipe 10 and the liquid outlet head 11 reach the appropriate height, the servo motor 19 is turned off, so that the liquid outlet pipe 10 and the liquid outlet head 11 stop moving, thus completing the adjustment of the height of the liquid outlet pipe 10 and the liquid outlet head 11. Since a sealing ring is fixedly installed on the inner wall at the bottom of the liquid passage pipe 6, and the sealing ring is also sleeved on the outer surface of the extension tube 8, the sealing between the liquid passage pipe 6 and the extension tube 8 can be guaranteed, preventing the electrolyte from leaking from the gap between the liquid passage pipe 6 and the extension tube 8.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
