Description

Technical Field

[0001] This invention relates to a battery recycling device, and more particularly to a precision-guided battery draining device. Background Technology

[0002] Lithium batteries, as a major carrier of new energy, are composed of copper and aluminum foil, nickel, cobalt, lithium manganese oxide salts, graphite, electrolyte, separator paper, etc. Most batteries contain a variety of toxic, corrosive or flammable organic solvents (such as carbonates) and electrolyte salts (such as lithium hexafluorophosphate) in their electrolyte. If the battery leaks or ruptures during subsequent crushing and dismantling, these liquids will directly endanger the health of operators (irritate the skin and eyes, inhale harmful volatile gases) and cause environmental pollution. Therefore, the electrolyte of existing batteries is treated before recycling.

[0003] Traditional equipment typically extracts electrolyte from batteries by squeezing it during the casing cutting process. However, this method yields a limited amount of electrolyte, and because subsequent casing-core separation is required, excessive squeezing force cannot be used to completely deform the casing. Therefore, existing equipment uses a pumping method to extract the electrolyte, which increases the discharge volume. However, this method is less effective when the battery is laid flat. Furthermore, standing the batteries upright not only delays the production schedule but also makes it difficult to ensure the stability of the batteries during the pumping process.

[0004] Therefore, this case aims to provide a precise-guided battery draining device that can turn the battery vertically at the feeding position so that the battery can drain in a vertical state. Multiple stations can be operated simultaneously, and a vacuum draining method is used at the battery's explosion-proof valve position to make it easier to drain the electrolyte during the pumping stage.

[0014] As a further improvement, the liquid discharge limiting bracket includes a platform transverse plate that slides along the liquid discharge platform. The upper end of the platform transverse plate is connected to a platform longitudinal plate. Two opposing platform longitudinal plates clamp the two sides of the battery. A liquid discharge platform guide rail is provided on the liquid discharge platform. A limiting bracket sliding block is provided at the bottom of the platform transverse plate.

When the sliding block swing push rod moves, the platform transverse plate moves accordingly.

[0015] As a further improvement, the discharge pipe includes a vacuum connection pipe connected to a vacuum device. The vacuum connection pipe is connected to a pipeline drive structure.

A linkage plate is connected to the output end of the pumping motor, and the linkage plate is penetrated by the vacuum connection pipe.

[0016] The beneficial effects of this invention are: Existing technologies have limited effectiveness in draining electrolyte when batteries are laid flat. Standing batteries upright not only delays the process but also makes it difficult to ensure stability during electrolyte extraction. Therefore, this invention utilizes a steering and positioning component to automate the entire process. A robotic arm loads batteries onto a steering table, which then pushes them into a steering tilting mechanism. The tilting mechanism holds the batteries and guides them along a steering guide until they are upright. The next station's gripping structure then transports the batteries to the electrolyte extraction position, enabling vertical battery loading and providing a better foundation for the extraction process. Simultaneously, the electrolyte loading and unloading structure moves to the battery position. The upper end clamps the battery, at which point an unloaded draining platform is pushed out by the corresponding platform position moving part, placing the battery on the draining limiting frame. The draining limiting structure clamps and fixes both sides of the battery through the draining limiting frame, ensuring that the battery position is determined. Then, the platform position moving part retracts to its original position, the battery piercing structure moves down, fixing the top surface of the battery. Finally, the lower draining structure rises, causing the lower draining structure to pierce into the battery's explosion-proof valve. Then, the vacuum equipment is activated to evacuate the inside of the battery. At this time, the electrolyte gradually flows out through the explosion-proof valve under the action of gravity and vacuum, thus allowing the battery to drain the electrolyte in a longitudinal state under multiple forces. The electrolyte is drained more thoroughly, and no manual intervention is required throughout the process.

[0017] During the battery loading process, since the platform position moving part can push the draining platform to the middle position, the draining and loading structure only needs to move along a straight line. Therefore, the draining fully enclosed screw module of the present invention moves along the draining robot guide rail, picks up the battery through the draining transfer gripper, and moves it to the corresponding row of the draining platform. After the draining platform is pushed out, the battery can be loaded.

[0018] During the vacuum extraction process, if the battery casing only has one extraction port (explosion-proof valve), the vacuum extraction effect is poor. Therefore, in addition to applying pressure to the top of the battery through the battery puncture structure, this invention also sets a top puncture nail on the pressure relief plate. As the pressure relief plate presses the top of the battery casing, the top puncture nail punctures the battery casing, thereby forming a certain gap at the top of the battery. When a vacuum suction force is generated at the bottom of the battery, it can help to extract the electrolyte better.

[0019] During loading, the battery is loaded via a steering table drive. Since the battery has just been discharged and still has a certain temperature, the steering table drive is located inside the steering table. Through the cooperation of the table guide frame and the table sliding motor, the extended sliding motor frame can move the battery to one side of the steering flipping component, thus achieving automatic loading.

[0020] During the flipping process of the steering component, it is necessary to support and fix the battery, so a fixed fulcrum is required. Therefore, the steering fixing guide of the present invention is provided with an inner guide, one end of which is a bearing and the other end is a rotating roller, so that the steering component is sleeved on the outside of the rotating roller, thereby using the inner guide as a fulcrum to realize the battery changing from the horizontal to the vertical direction.

[0021] During the battery flipping process, since the battery changes at least 90 degrees, the angle change of the entire steering flipping component is relatively large. Therefore, both ends of the steering flipping push rod of the present invention are hinged by hinge seats, which makes the angle change of the flipping seat more flexible.

[0022] After the flip stand is successfully flipped, the stability of the battery also needs to be considered. The battery changes from a horizontal to a vertical position, and it changes from one fixed support surface to three fixed support surfaces. Therefore, on the premise that the flip stand already has a fixed support function, it is also necessary to set up a first clamping member and a second clamping member to form a U-shaped fixed structure for limiting and fixing.

[0023] Due to the different specifications of the batteries, some batteries are too tall during the bottom support process, making them unable to be stably supported. Therefore, the bottom support plate of the first clamping member of the present invention can change the distance between itself and the flipping seat by adjusting the support push rod and the side extension frame, thereby supporting batteries with higher height and wider width and improving the adaptability of the present invention.

[0024] During the battery flipping process, although it is restricted in three directions, there is still a certain probability that it will slide out from the side. Therefore, the present invention also provides a side guide component on the other side of the turning fixed guide, so as to limit the side direction in real time during the battery flipping process, prevent the battery from sliding out from the side position, and reduce the frequency of manual intervention.

[0025] The liquid discharge device is actually not just one set. In order to facilitate the feeding of the liquid discharge device, the present invention connects the liquid discharge platform with the platform position moving part. The liquid discharge platform moving motor on the platform position moving part pushes the entire liquid discharge platform to a fixed position. After the trolley feeds the liquid, it retracts to the original position, thereby achieving the effect of centered feeding and segmented liquid discharge.

[0026] In the process of clamping the battery, it is not just fixed by a narrow plate. In this invention, whether the battery is large or small, it is clamped and fixed by a full-length platform longitudinal sliding plate, so as to ensure the clamping effect.

[0027] In order to maintain the accuracy of its movement trajectory and the stability after clamping the battery, the present invention sets a platform transverse plate at the lower end of the platform longitudinal plate during the process of the platform longitudinal plate moving towards the battery. The platform transverse plate cooperates with the liquid discharge platform guide rail through the limiting frame sliding block, so that the platform transverse plate can drive the platform longitudinal plate to move laterally under the action of external power, thereby clamping or releasing the battery.

[0028] In accordance with safety principles, the power source for the platform transverse plate is not located on the surface of the platform transverse plate. In this invention, the liquid discharge limiting drive structure is located at the lower end of the liquid discharge platform, and the medium connecting it to the platform transverse plate is a sliding block swing rod that passes through a short groove. One sliding block swing push rod can connect two sliding block swing rods, so that the movement of two platform transverse plates can be realized by one sliding block swing push rod. Under the premise that the platform transverse plate moves along the liquid discharge platform guide rail, the movement of the battery becomes more controllable and safe.

[0029] Once the battery is secured, electrolyte extraction can begin. To improve the efficiency and safety of electrolyte discharge during extraction, this invention places the plunger of the leakage platform at the bottom of the battery explosion-proof valve. After the explosion-proof valve is punctured by the plunger, the electrolyte flows downward through the leakage platform. The leakage platform is connected to a separate discharge pipe to prevent it from flowing into the vacuum equipment.

[0030] Since the battery is pumped vertically, there may be some electrolyte deposits at the bottom of the battery. When the explosion-proof valve is initially punctured, a large amount of electrolyte will gush out. At this time, the leakage platform cannot absorb all of it at once, which may lead to electrolyte overflow. Therefore, the present invention also provides a suction cup at the top of the vacuum connection tube. On the one hand, the suction cup can improve the fit between the discharge tube and the battery to ensure the sealing during vacuuming. On the other hand, the suction cup can catch the leaked electrolyte to prevent electrolyte leakage.

[0031] When the vacuum connecting tube is used with the battery, it cannot rely solely on the weight of the battery itself. If the weight of some small batteries is insufficient, gaps may appear between the vacuum connecting tube and the battery, thus affecting the liquid extraction effect. Therefore, this invention sets the vacuum connecting tube on a pipeline driving structure, which drives the vacuum connecting tube to move up and down, making the vacuum connecting tube and the battery fit more tightly.

Detailed Implementation

[0047] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0048] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating that the purpose, technical solution, and advantages of the method are clearer. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] Reference Figures 1 to 13 As shown, a precision-guided battery draining device includes: a draining cabinet 54, with several support arms inside the draining cabinet 54, a draining gantry 56 on each support arm, a draining loading structure 57 on the draining gantry 56, and several battery puncture structures 58 arranged in the same row of the draining loading structure 57; it also includes a battery steering and positioning structure and a battery draining device; the battery steering and positioning structure includes: a steering worktable 40, with a steering worktable drive 41 on the steering worktable 40, the steering worktable drive 41 pushing the battery to the steering position; a steering positioning assembly 42, including a steering fixing guide 421 that fits against the end of the steering worktable 40, a steering flipping member 422 movably mounted on the inner side of the steering fixing guide 421, and a steering clamping member 423 on the steering flipping member 422; when the steering worktable drive 41 pushes the battery to the steering flipping member 422, the battery is drained through the steering clamping member 423. The holding member 423 clamps the battery and allows the turning and flipping member 422 to move along the turning and fixing guide member 421 until the battery is in a vertical position; the battery draining device includes: a draining platform 50, which is connected to a platform position moving member 51, which moves the draining platform 50 to the middle of the draining cabinet 54; a draining limiting structure 52, which includes a draining limiting bracket 521 disposed on the draining platform 50, the draining limiting bracket 521 being connected to a draining cabinet 54. Driven by the limiting drive structure 522, after the liquid discharge feeding structure 57 moves the battery to the liquid discharge platform 50, the liquid discharge limiting drive structure 522 drives the liquid discharge limiting frame 521 to clamp and fix the battery; the lower liquid discharge structure 53 has at least one hole on the liquid discharge platform 50, and the lower liquid discharge structure 53 includes a liquid discharge pipe 531 disposed in the hole. The liquid discharge pipe 531 is driven by a pipeline drive structure 532, and the pipeline drive structure 532 is fixed to the bottom of the liquid discharge platform 50.

[0050] Existing technologies have limited effectiveness in draining electrolyte when batteries are laid flat. Standing batteries upright not only delays the process but also makes it difficult to ensure stability during electrolyte extraction. Therefore, this invention utilizes a steering and positioning component to automate the entire process. A robotic arm loads batteries onto a steering table, which then pushes them into a steering tilting mechanism. A steering clamp holds the batteries, guiding them along a steering guide until they are vertical. The next station's gripping structure then transports the batteries to the electrolyte extraction position, enabling vertical battery loading and providing a better foundation for the extraction operation. Simultaneously, the electrolyte loading and unloading structure 57 moves to the top of the batteries... The battery is clamped up, and at this time, an unloaded draining platform 50 is pushed out by the corresponding platform position moving part 51, so that the battery is placed on the draining limiting frame 521. The draining limiting structure clamps and fixes the two sides of the battery through the draining limiting frame to ensure that the battery position is determined. Then, the platform position moving part 51 retracts to its original position, the battery piercing structure 58 moves down and fixes the top surface of the battery. Finally, the lower draining structure is raised so that the lower draining structure is inserted into the battery's explosion-proof valve. Then, the vacuum equipment is activated to evacuate the inside of the battery. At this time, the electrolyte is gradually discharged through the explosion-proof valve under the action of gravity and vacuum. Thus, the electrolyte is discharged from the battery in a longitudinal state under multiple forces, making the electrolyte discharge more thorough. No manual intervention is required throughout the process.

[0051] During the battery loading process, since the platform position moving part 51 can push the draining platform 50 to the middle position, the draining loading structure 57 only needs to move along a straight line. Therefore, the draining loading structure 57 in this embodiment includes a draining robot guide rail 571 fixed on the draining gantry frame 56. A draining fully enclosed screw module 572 is slidably connected to the draining robot guide rail 571. A draining transfer gripper 573 is locked on the draining fully enclosed screw module 572. The draining fully enclosed screw module 572 moves along the draining robot guide rail 571, and the draining transfer gripper 573 picks up the battery and moves it to the column of the draining platform 50 at the corresponding position. After the draining platform 50 is pushed out, the battery can be loaded.

[0052] During vacuum extraction, if the battery casing only has one extraction port (explosion-proof valve), the vacuum extraction effect is poor. Therefore, in this embodiment, the battery puncture structure 58 is set at the upper end of the battery draining device and corresponds to it. The battery puncture structure 58 includes a puncture motor 581 set on the draining gantry 56. The lower end of the puncture motor 581 is connected to a draining pressure plate 582. A top puncture nail 583 is connected to the draining pressure plate 582. During the process of applying pressure to the top of the battery through the battery puncture structure 58, the top puncture nail 583 is also set on the draining pressure plate 582. As the draining pressure plate 582 presses the top shell of the battery, the top puncture nail 583 will puncture the battery casing, thereby forming a certain gap at the upper end of the battery. When a vacuum suction force is generated at the lower end of the battery, it can help to extract the electrolyte better.

[0053] Existing technologies have limited effectiveness in draining electrolyte when batteries are laid flat during the electrolyte extraction process. However, standing the batteries upright one by one would significantly delay the process. Therefore, this embodiment utilizes a fully automated steering and positioning component 42. A robotic arm loads the batteries onto the steering worktable 40, and the steering worktable drive 41 pushes the batteries into the steering flipping component 422. The steering clamping component 423 holds the batteries in place, and the steering flipping component 422 moves along the steering fixing guide 421 until the batteries are in an upright position. Then, the next station's gripping structure transports the batteries to the position of the electrolyte extraction structure. This allows for vertical loading of the batteries, providing a better operational foundation for the electrolyte extraction operation.

[0054] During loading, the battery is loaded via the steering table drive 41. Since the battery has just been discharged and still has a certain temperature, the steering table 40 in this embodiment has a horizontal groove 400 on its upper surface. The steering table drive 41 includes a table guide 411 disposed inside the steering table 40. A table sliding motor 412 is disposed inside the table guide 411, and a sliding motor extension 413 is disposed on the top of the table sliding motor 412. The sliding motor extension 413 passes through the horizontal groove 400. The steering table drive 41 is disposed inside the steering table 40. Through the cooperation of the table guide 411 and the table sliding motor 412, the extended sliding motor extension 413 can move the battery to one side of the steering flipper 422, thereby achieving automatic loading.

[0055] During the rotation of the steering and flipping component 422, it needs to support and fix the battery, so it requires a fixed fulcrum. Therefore, the steering fixing guide component 421 in this embodiment includes a guide mounting frame 4211 connected to the steering worktable 40. The lower end of the guide mounting frame 4211 is provided with a power mechanism mounting plate 4212. The inner side of the guide mounting frame 4211 is provided with an inner guide component 4213. The steering and flipping component 422 rotates along the inner guide component 4213. The steering fixing guide component 421 is provided with an inner guide component 4213. One end of the inner guide component 4213 is a bearing, and the other end is a rotating roller. The steering and flipping component 422 is sleeved on the outside of the rotating roller, so that the battery changes from horizontal to vertical with the inner guide component 4213 as the fulcrum.

[0056] During the battery flipping process, since the battery changes at least 90 degrees, the angle change of the entire steering flipping component 422 is relatively large. Therefore, in this embodiment, the steering flipping component 422 includes a first hinge seat 4221 connected to the lower power mechanism mounting plate 4212. A steering flipping push rod 4222 is mounted on the first hinge seat 4221. A second hinge seat 4223 is connected to the top of the steering flipping push rod 4222. The second hinge seat 4223 is connected to a flipping seat 4224. The steering clamping component 423 is disposed on the flipping seat 4224. Both ends of the steering flipping push rod 4222 are hinged through the hinge seats, thereby making the angle change of the flipping seat 4224 more flexible.

[0057] After the flip seat 4224 is successfully flipped, the stability of the battery also needs to be considered. The battery changes from a horizontal to a vertical position, and it changes from one fixed support surface to three fixed support surfaces. Therefore, under the premise that the flip seat 4224 already has a fixed support function, the steering clamp 423 of this embodiment includes a first clamp 4231 disposed in the flip seat 4224 and extending to the side of the flip seat 4224. A second clamp 4232 is disposed on the side of the first clamp 4231 away from the flip seat 4224. The first clamp 4231 and the second clamp 4232 are used to form a U-shaped fixed structure for limiting and fixing.

[0058] Due to the different specifications of the batteries, some batteries are too tall during the bottom support process, making them unstable to be supported. Therefore, the first clamping member 4231 in this embodiment includes a support push rod 42311 disposed inside the flip base 4224. A side extension frame 42312 is connected to the output end of the support push rod 42311. A bottom support plate 42313 is locked in the middle section of the side extension frame 42312. The bottom support plate 42313 of the first clamping member 4231 can change the distance between itself and the flip base 4224 by adjusting the support push rod 42311 and the side extension frame 42312, thereby supporting batteries with higher height and wider width and improving the adaptability of the present invention.

[0059] The second clamping member 4232 uses a normal clamping method. Specifically, the second clamping member 4232 includes a lateral clamping motor 42321 that is locked to the outer side of the base plate 42313. A side clamping plate 42322 is provided on the output end of the lateral clamping motor 42321. The side clamping plate 42322, the base plate 42313, and the upper plate of the flip seat 4224 form a U-shaped structure that limits the battery. The difference from the prior art is that it is set on the base plate 42313 and changes with the position adjustment of the base plate 42313 itself.

[0060] During the battery flipping process, although it is restricted in three directions, there is still a certain probability that it will slide out from the side. Therefore, in this embodiment, a side guide component 43 is provided on the side of the steering fixing guide 421 away from the steering flipping component 422. The side guide component 43 includes a side adjustment push rod 431 disposed on the side of the steering fixing guide 421. A double-ended mounting base 432 is provided at the top of the side adjustment push rod 431. A side adjustment motor 433 is provided at both ends of the double-ended mounting base 432. An elongated limiting rod 434 is provided on the output end of the side adjustment motor 433. By also providing a side guide component 43 on the other side of the steering fixing guide 421, the side direction can be limited in real time during the battery flipping process, preventing the battery from sliding out from the side and reducing the frequency of manual intervention.

[0061] The effect of draining electrolyte is limited when the battery is laid flat. However, if the batteries are stood upright one by one, it will not only delay the construction period, but also make it difficult to ensure the stability of the battery during the electrolyte extraction process. Therefore, in this embodiment, after the battery is in place, the two sides of the battery are first clamped and fixed by the electrolyte draining limit structure 52 and the electrolyte draining limit frame 521 to ensure that the battery position is determined. Then, the top is pressed and punched. Finally, the lower electrolyte draining structure 53 is raised so that the lower electrolyte draining structure 53 is inserted into the battery's explosion-proof valve. Then, the vacuum equipment is started to evacuate the battery. At this time, the electrolyte is gradually discharged through the explosion-proof valve under the action of gravity and vacuum. Thus, the electrolyte is discharged from the battery in a vertical state under multiple forces, and the electrolyte is discharged more thoroughly.

[0062] In the entire battery draining production line, there is actually more than one set of draining devices. In order to facilitate the feeding of draining devices, the platform position moving part 51 in this embodiment includes a remote fixing part 511. A draining platform moving motor 512 is fixed on the remote fixing part 511. A proximal fixing part 513 is locked on the output end of the draining platform moving motor 512. The top of the proximal fixing part 513 is connected to the lower end of the draining platform 50, connecting the draining platform 50 to the platform position moving part 51. The draining platform moving motor 512 on the platform position moving part 51 pushes the entire draining platform 50 to a fixed position. After the trolley feeds the material, it retracts to the original position, thereby achieving the effect of centered feeding and segmented draining.

[0063] During the battery clamping process, it is not simply fixed by a narrow plate. In this embodiment, the drain limiting frame 521 includes a platform transverse plate 5211 that slides along the drain platform 50. The upper end of the platform transverse plate 5211 is connected to a platform longitudinal plate 5212. The two opposing platform longitudinal plates 5212 clamp the two sides of the battery. Whether the battery is large or small, it is clamped and fixed by the entire platform longitudinal plate 5212, thereby ensuring the clamping effect.

[0064] During the process of the platform longitudinal plate 5212 moving towards the battery, in order to maintain the accuracy of its movement trajectory and the stability after clamping the battery, the liquid discharge platform 50 in this embodiment is provided with a liquid discharge platform guide rail 500, and a limiting frame sliding block 5213 is provided at the bottom of the platform transverse plate 5211. The limiting frame sliding block 5213 slides with the liquid discharge platform guide rail 500. The platform transverse plate 5211 is provided at the lower end of the platform longitudinal plate 5212, and the platform transverse plate 5211 cooperates with the liquid discharge platform guide rail 500 through the limiting frame sliding block 5213, so that the platform transverse plate 5211 can drive the platform longitudinal plate 5212 to move laterally under the action of external power, thereby clamping or releasing the battery.

[0065] In accordance with safety principles, the power source for the platform transverse plate 5211 is not located on its surface. In this embodiment, the surface of the liquid discharge platform 50 is provided with several short grooves 510. The liquid discharge limiting drive structure 522 includes a sliding block swing push rod 5221 located below the short grooves 510. Two sliding block swing rods 5222 are hinged to the top of the sliding block swing push rod 5221. The two sliding block swing rods 5222 are connected to the side of the platform transverse plate 5211. When the sliding block swing push rod 5221... During operation, the platform transverse plate 5211 moves accordingly, setting the liquid discharge limiting drive structure 522 at the lower end of the liquid discharge platform 50. The medium connecting it to the platform transverse plate 5211 is a sliding block swing rod 5222 that passes through the short groove 510. One sliding block swing push rod 5221 can connect two sliding block swing rods 5222, so that the movement of two platform transverse plates 5211 can be realized by one sliding block swing push rod 5221. Under the premise that the platform transverse plate 5211 moves along the liquid discharge platform guide rail 500, the movement of the battery becomes more controllable and safe.

[0066] Once the battery is secured, electrolyte extraction can begin. To improve the efficiency and safety of electrolyte discharge during extraction, the discharge pipe 531 in this embodiment includes a vacuum connection pipe 5311 connected to a vacuum device. The vacuum connection pipe 5311 is connected to the pipeline drive structure 532. A drain platform 5312 is provided at the top of the vacuum connection pipe 5311, and a pin 5313 is provided at the top of the drain platform 5312. The pin 5313 of the drain platform 5312 is positioned below the battery explosion-proof valve. After the explosion-proof valve is punctured by the pin 5313, the electrolyte flows downward through the drain platform 5312. The drain platform 5312 is connected to a separate discharge pipeline to prevent it from flowing into the vacuum device.

[0067] Since the battery is pumped in a vertical position, there may be some electrolyte deposits at the bottom of the battery. When the explosion-proof valve is initially punctured, a large amount of electrolyte will gush out. At this time, the leakage platform 5312 cannot absorb all of it at once, which may lead to electrolyte overflow. Therefore, the diameter of the leakage platform 5312 in this embodiment is smaller than that of the vacuum connecting tube 5311. A suction cup 5314 is provided on the outer edge of the vacuum connecting tube 5311, and a suction cup 5314 is also provided on the top of the vacuum connecting tube 5311. On the one hand, the suction cup 5314 can improve the fit between the discharge tube 531 and the battery to ensure the sealing during vacuuming. On the other hand, the suction cup 5314 can catch the leaked electrolyte and prevent electrolyte leakage.

[0068] When the vacuum connecting tube 5311 is fitted with the battery, it cannot rely solely on the weight of the battery itself. If the weight of some small batteries is insufficient, gaps may appear in the fit between the vacuum connecting tube 5311 and the battery, thus affecting the liquid extraction effect. Therefore, the pipeline drive structure 532 in this embodiment includes a liquid extraction platform connecting plate 5321 connected to the liquid extraction platform 50. A liquid extraction start-stop motor 5322 is fixed on the liquid extraction platform connecting plate 5321. A linkage plate 5323 is connected to the output end of the liquid extraction start-stop motor 5322. The linkage plate 5323 is penetrated by the vacuum connecting tube 5311, which sets the vacuum connecting tube 5311 onto the pipeline drive structure 532. The pipeline drive structure 532 drives the vacuum connecting tube 5311 to move up and down, making the fit between the vacuum connecting tube 5311 and the battery tighter.

[0069] To improve the strength of the platform transverse plate 5211 and the platform longitudinal plate 5212, and to prevent insufficient pressure when clamping batteries of larger specifications, the platform transverse plate 5211 and the platform longitudinal plate 5212 are connected by a triangular rib plate 5214 to form a triangular structure for support.

[0070] During the liquid extraction process, it is necessary to ensure that the battery is in the work position. Therefore, the platform transverse plate 5211 in this embodiment is equipped with a sensor, which can be an infrared sensor or other proximity sensor. The top fixing action and liquid extraction action will only be performed when the battery is detected to be in place.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
