Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically a zinc-ion battery liquid injection machine. Background Technology

[0002] Electrolyte, as a core component of zinc-ion batteries, plays a decisive role in battery performance. It not only serves as the medium for zinc ion transport between the positive and negative electrodes but also directly affects the battery's charge-discharge efficiency, cycle life, and safety. In the manufacturing process of zinc-ion batteries, the electrolyte filling process is a crucial step.

[0003] Chinese patent CN221994677U discloses a lithium battery filling machine. This patent features an active roller and a driven roller on the front surface of a workbench, with a conveyor belt on their surfaces. A first motor drives the active roller to rotate, facilitating the automatic delivery of lithium batteries and improving production efficiency. Furthermore, a second motor is installed at the top of the storage tank, with a rotating shaft and stirring blades at its output end, facilitating the stirring of the electrolyte and preventing coagulation and precipitation. This design is highly practical.

[0004] However, during the liquid injection process, when the injection nozzle is removed from the lithium battery after injection, electrolyte may remain at the tip of the nozzle. When the residual electrolyte drips onto the conveyor belt, it not only pollutes the production environment, but also easily damages the conveyor belt due to the corrosive nature of the electrolyte, affecting its service life. Utility Model Content

[0005] The purpose of this invention is to provide a zinc-ion battery filling machine that effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A zinc-ion battery filling machine includes a U-shaped frame. A drive plate is disposed on the lower side of the U-shaped frame, and an electric push rod is mounted on the lower surface of the drive plate. A horizontal tube is mounted on the telescopic end of the electric push rod, and multiple filling nozzles are arranged along the length of the lower surface of the horizontal tube. A receiving box is mounted below the filling nozzles via a transmission mechanism. The transmission mechanism can retract the receiving box when the horizontal tube descends and extend the receiving box directly below the filling nozzles when they rise to their reset position. A translation mechanism is disposed between the two side walls of the U-shaped frame, which can drive the drive plate to move horizontally.

[0008] Furthermore, the transmission mechanism includes a hanging plate mounted on the lower surface of the drive plate. A first guide rod is transversely inserted through the interior of the hanging plate, and one end of the first guide rod is connected to the receiving box. A connecting plate is mounted on the other end of the first guide rod, and a second guide rod is mounted on the outer surface of the connecting plate. The end of the second guide rod transversely extends to the other side of the hanging plate and is fitted with a pressing end. A pressing plate is mounted on the outer surface of the telescopic end of the electric push rod, and the pressing plate and the pressing end are in a pressing fit. A spring is sleeved on the outer surface of the first guide rod, and the two ends of the spring abut against the hanging plate and the receiving box, respectively.

[0009] Furthermore, the translation mechanism includes a limiting rod installed between the inner walls on both sides of the U-shaped frame, and a drive plate slidably installed on the limiting rod. A threaded rod is rotatably installed between the inner walls on both sides of the U-shaped frame, and the drive plate is installed on the threaded rod. A servo motor is installed on the outer surface of the U-shaped frame, and the output shaft of the servo motor is connected to the threaded rod.

[0010] Furthermore, a drain pipe is installed on the outer surface of the receiving box, and a valve is installed on the drain pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a zinc-ion battery filling machine, including a U-shaped frame 1. A drive plate 101 is arranged on the lower side of the U-shaped frame 1. An electric push rod 102 is installed on the lower surface of the drive plate 101. A horizontal tube 103 is installed at the telescopic end of the electric push rod 102. Multiple filling nozzles 104 are arranged along the length of the lower surface of the horizontal tube 103. A receiving box 105 is installed below the filling nozzles 104 through a transmission mechanism 2. The transmission mechanism 2 can drive the receiving box 105 to retract when the horizontal tube 103 descends, and drive the receiving box 105 to extend directly below the filling nozzles 104 when they rise and reset. A translation mechanism 3 is arranged between the two side walls of the U-shaped frame 1. The translation mechanism 3 can drive the drive plate 101 to move horizontally.

[0023] In use, the U-shaped frame 1 is installed above the conveyor belt (not shown in the figure), and the batteries are placed on the tray for conveying. When the conveyor belt conveys the tray to the bottom of the injection nozzle 104, it stops. Then, the electric push rod 102 drives the horizontal tube 103 to descend, and multiple injection nozzles 104 are simultaneously inserted into the inside of a row of batteries for liquid injection. During the descent of the injection nozzle 104, the transmission mechanism 2 drives the receiving box 105 to retract and move out from directly below the injection nozzle 104, thus avoiding obstruction of the injection nozzle 104. After the injection nozzle 104 has finished injecting, the electric push rod 102 drives it to rise. When the injection nozzle 104 rises above the receiving box 105, the transmission mechanism 2 drives the receiving box 105 to reset and extend back to the bottom of the injection nozzle 104. When electrolyte drips from the injection nozzle 104, the receiving box 105 can catch it, thus preventing electrolyte from dripping randomly and polluting the production environment and corroding the conveyor belt.

[0024] After the electrolyte filling of one row of batteries is completed, the translation mechanism 3 drives the filling nozzle 104 to move laterally, and fills each row of batteries on the tray with electrolyte in turn. During the lateral movement of the filling nozzle 104, the receiving box 105 can always be directly below the filling nozzle 104 to ensure the receiving of electrolyte.

[0025] Preferably, the transmission mechanism 2 includes a hanging plate 206 mounted on the lower surface of the drive plate 101. A first guide rod 201 is transversely arranged inside the hanging plate 206, and one end of the first guide rod 201 is connected to the receiving box 105. A connecting plate 202 is mounted on the other end of the first guide rod 201. A second guide rod 203 is mounted on the outer surface of the connecting plate 202. The end of the second guide rod 203 transversely extends to the other side of the hanging plate 206 and is fitted with a pressing end 204. A pressing plate 205 is mounted on the outer surface of the telescopic end of the electric push rod 102, and the pressing plate 205 and the pressing end 204 are press-fitted together. A spring 207 is sleeved on the outer surface of the first guide rod 201, and the two ends of the spring 207 abut against the hanging plate 206 and the receiving box 105, respectively.

[0026] When the electric push rod 102 drives the injection nozzle 104 to descend, the telescopic end of the electric push rod 102 drives the extrusion plate 205 to descend synchronously. When the extrusion plate 205 descends, its inclined surface squeezes the extrusion end 204, which in turn pushes the extrusion end 204 to drive the second guide rod 203 to move laterally. The second guide rod 203 drives the receiving box 105 to move laterally and compress the spring 207 through the connecting plate 202 and the first guide rod 201, so that the extrusion plate 205 moves out from directly below the injection nozzle 104. At this time, the receiving box 105 will not obstruct the bottom of the injection nozzle 104, allowing it to descend normally for injection.

[0027] After the electrolyte injection is completed, the electric push rod 102 drives the injection nozzle 104 to rise. When the injection nozzle 104 moves above the receiving box 105, the inclined surface of the extrusion plate 205 contacts the extrusion end 204. At this time, the compressed spring 207 releases its elastic force, thus pushing the receiving box 105 to reset and extend it back to directly below the injection nozzle 104 to collect the electrolyte.

[0028] Furthermore, the entire operation requires no additional driving source, which not only saves costs but also has a low failure rate, ensuring stable contact with the electrolyte.

[0029] Preferably, the translation mechanism 3 includes a limiting rod 301 installed between the inner walls of both sides of the U-shaped frame 1, and a drive plate 101 is slidably installed on the limiting rod 301. A threaded rod 302 is rotatably installed between the inner walls of both sides of the U-shaped frame 1, and the drive plate 101 is installed on the threaded rod 302. A servo motor 303 is installed on the outer surface of the U-shaped frame 1, and the output shaft of the servo motor 303 is connected to the threaded rod 302.

[0030] When the servo motor 303 is started, it drives the threaded rod 302 to rotate. Since the limiting rod 301 limits the drive plate 101, the drive plate 101 can move along the length of the threaded rod 302 under the action of the threaded connection, and achieve the purpose of driving the injection nozzle 104 to move laterally.

[0031] Preferably, a drain pipe 4 is installed on the outer surface of the receiving box 105, and a valve 401 is installed on the drain pipe 4.

[0032] After a certain amount of electrolyte is collected inside the receiving box 105, the valve 401 can be opened to discharge it.

[0033] Preferably, linear bearings 5 ​​are installed on both sides of the drive plate 101, and guide posts 501 are installed on both sides of the outer surface of the horizontal tube 103, and the guide posts 501 are slidably installed in the linear bearings 5.

[0034] When the extrusion plate 205 extrudes the extrusion end 204, the telescopic end of the electric push rod 102 will be subjected to a lateral force. Therefore, by setting the linear bearing 5 and the guide post 501, the limiting effect on the telescopic end of the electric push rod 102 can be strengthened, the lateral force it is subjected to can be reduced, and the performance and service life of the electric push rod 102 can be guaranteed.

[0035] Preferably, a liquid storage tank 6 is installed on the top of the U-shaped frame 1, a pump body 601 is installed on the outer surface of the liquid storage tank 6, a hose 602 is connected to the output end of the pump body 601, and the end of the hose 602 is connected to the horizontal pipe 103.

[0036] The electrolyte in the storage tank 6 is drawn out by the pump body 601 and injected into the horizontal tube 103 through the hose 602 to achieve the purpose of liquid supply. The hose 602 is made of flexible material and can adapt to changes in the position of the horizontal tube 103.

[0037] Preferably, a liquid level sensor is installed inside the liquid storage tank 6, and a replenishment pipe 603 is connected to the top of the liquid storage tank 6.

[0038] When the level sensor detects that the electrolyte level in the storage tank 6 has dropped to a certain level, it can automatically supply electrolyte through the external liquid supply device using the replenishment pipe 603, ensuring the continuity of production and reducing manual intervention.
