One side of the top of the base is fixedly connected to the bottom of a lifting plate. A lifting roller is fixedly installed inside the lifting plate. A first motor is fixedly installed at the bottom of the front of the lifting plate, and the output end of the first motor is connected to the drive shaft of the lifting roller. The top of one side of the lifting plate is fixedly connected to one side of a top plate. Several quantitative dripping devices are fixedly installed at the bottom of the top plate through several connecting columns. Moving wheels are fixedly installed at the corners of the bottom of the base. This device quantitatively drips the electrolyte. Several internal stirring devices facilitate the uniform mixing of the electrolyte and injected additives, resulting in high electrolyte quality. The quantitative dripping devices are easy to install and clean, and have high cleaning efficiency. It can drip the electrolyte onto multiple lithium-ion batteries. However, this patent still has the following problems in actual use:

Similar to the existing injection method, it is necessary to manually observe the electrolyte scale, which is not conducive to continuous production and is quite inconvenient.

[0005] A device for adding button battery electrolyte in a quantitative manner is proposed to solve the problems mentioned above. Utility Model Content

At this time, it is necessary to manually observe the comparison between the electrolyte level and the scale of the metering tube in real time, so as to control the opening and closing of the second valve in time, thereby achieving quantitative electrolyte injection. This is the same as the existing injection method, which requires manual observation of the electrolyte scale, which is not conducive to continuous production and is quite inconvenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a button battery electrolyte addition device that can add a quantitative amount of electrolyte, including a processing table, on which a robotic arm is rotatably mounted, and an installation head is rotatably mounted at the output end of the robotic arm;

A driven wheel is fixedly connected to the outside of the threaded sleeve. An extension plate is fixedly connected to the outside of the adjusting tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This button battery electrolyte adding device, which can add a fixed amount of liquid each time, by vertically changing the height of the limiting plate, ensures that the amount of liquid injected into the cavity below the compression plate is fixed each time. Finally, when the electric pusher pushes the compression plate downward to expel the liquid, the amount expelled each time is fixed, avoiding the need for manual observation each time liquid is added, thus simplifying operation. The specific details are as follows:

[0017] 1. By rotating the shaft, the drive wheel drives the driven wheel to rotate via a belt, causing the threaded tube to move vertically. This, in turn, changes the height of the limiting plate vertically. As a result, each time the electric actuator retracts, the limiting plate prevents the electric actuator from moving the compression plate upward. This ensures that the amount of liquid injected into the cavity below the compression plate is constant each time. Finally, when the electric actuator pushes the compression plate downward to expel liquid, the amount expelled is always constant, avoiding the need for manual observation each time liquid is added, thus simplifying operation.

[0018] 2. The support spring will push the upper sealing plate to fit against the lower sealing plate, preventing liquid from leaking out under gravity. Attached Figure Description

[0027] The mounting head 102 is provided with a metering component 2, which includes an electric actuator 201 fixedly mounted on the top of the mounting head 102. An adjusting tube 202 is fixedly connected to the bottom of the mounting head 102, and a liquid storage tube 203 is fixedly connected to the bottom of the adjusting tube 202.

The threaded tube 205 can also pass through the top of the adjusting tube 202 and extend into the inside of the mounting head 102, and the threaded tube 205 extends into the inside of the liquid storage tube 203.

[0028] The piston rod of the electric actuator 201 passes through the threaded tube 205 and is fixedly connected to the compression plate 207.

A pair of fixing plates 208 are fixedly connected inside the regulating tube 202. The fixing plates 208 are rotatably connected to the outside of the threaded sleeve 209. The rectangular liquid storage tube 203 and the limiting plate 206 can prevent the threaded tube 205 from rotating.

[0030] A serrated block 213 is fixedly connected to the bottom of the extension plate 211. A locking block 216 is engaged with the bottom of the serrated block 213. A rotating shaft 212 is fixedly connected to the middle of the locking block 216. The rotating shaft 212 passes through the middle of the serrated block 213. The rotating shaft 212 can slide and rotate within the extension plate 211.

[0031] The locking block 216 is externally rotatably connected to a rotating ring 217. A pull spring 218 is fixedly connected between the top surface of the rotating ring 217 and the bottom surface of the extension plate 211. The pull spring 218 pulls the locking block 216 to engage with the serrated block 213.

[0032] A through groove is provided on the side of the regulating pipe 202, through which the belt 215 passes. A vertical scale 204 is provided on the outside of the liquid storage pipe 203, and a liquid supply pipe is fixedly installed on one side of the bottom of the liquid storage pipe 203. The vertical scale 204 is aligned with the bottom surface of the limiting plate 206 at a height that represents the volume of liquid that can be contained in the cavity below when the compression plate 207 is in contact with the limiting plate 206 at this time. The belt 215 can move up and down slightly within the through groove. The liquid supply pipe can automatically supply liquid through a valve, which is existing technology.

[0035] Working principle: Before using this button battery electrolyte adding device that can add a precise amount of electrolyte, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, by rotating the shaft 212, the drive wheel 214 drives the driven wheel 210 to rotate via the belt 215, thereby causing the threaded tube 205 to move vertically, which in turn causes the height of the limiting plate 206 to change vertically. With the help of the vertical scale 204, the size of the cavity below the compression plate 207 is confirmed when the compression plate 207 is attached to the limiting plate 206. Then, each time the electric actuator 201 retracts, the limiting plate 206 will prevent the electric actuator 201 from moving the compression plate 207 upward, thereby ensuring that the amount of liquid injected into the cavity below the compression plate 207 is fixed each time. Finally, when the electric actuator 201 pushes the compression plate 207 downward to expel the liquid, the amount expelled each time is fixed, avoiding the need for manual observation each time liquid is added, and making the operation easier.

[0036] When liquid is supplied through the supply pipe, the support spring 304 pushes the upper sealing plate 302 to fit against the lower sealing plate 303 to prevent liquid from leaking out under gravity. When the compression plate 207 descends, the hydraulic pressure squeezes the upper sealing plate 302 to rotate downward, thereby causing the liquid to flow out from between the upper sealing plate 302 and the lower sealing plate 303.

[0037] Under normal conditions, pulling the spring 218 will cause the locking block 216 to engage with the serrated block 213, thus preventing the rotating shaft 212 from rotating freely, and consequently locking the position of the limiting plate 206.

[0038] Although the present invention 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 invention should be included within the protection scope of the present invention.
