[0001] This invention belongs to the field of battery processing technology, and particularly relates to a battery vacuum liquid suction device and its control method. Background Technology

[0002] With the continuous development of digital technology and the gradual popularization of digital products, the number of high-current, high-power electrical appliances powered by batteries is increasing, placing higher demands on battery performance, particularly the need to maintain excellent and durable performance under heavy loads. Research shows that the performance degradation of alkaline dry batteries after discharge under heavy loads or after storage is largely due to the reduction or drying of the electrolyte in the battery. Current battery electrolyte absorption devices mainly involve absorbing electrolyte in the battery storage tray at atmospheric pressure or using a vacuum chamber. However, existing vacuum chambers often suffer from manufacturing difficulties and transportation inconveniences. Therefore, there is an urgent need for a flexible, convenient, and well-sealed battery vacuum electrolyte absorption device and its control method. Summary of the Invention

[0009] In the aforementioned battery vacuum liquid suction device, a baffle adapted to the groove is installed on one side of the movable side plate. When the battery is in the loading and unloading state, the baffle engages with the groove.

[0010] In the aforementioned battery vacuum liquid suction device, the bottom of the liquid suction section is connected to a vacuum assembly for evacuating the liquid suction section and a vacuum release assembly for releasing the vacuum. The bottom of the liquid suction section is also connected to a vacuum gauge for detecting the vacuum level information of the liquid suction section.

[0016] S4: The real-time vacuum level monitored by the vacuum gauge is sent to the controller, and the controller determines whether the real-time vacuum level has reached the preset vacuum level. If yes, proceed to step S5; otherwise, continue evacuating.

[0017] S5: The controller stops the vacuum assembly from pumping vacuum and keeps the containment cavity in a vacuum state for a preset time.

[0018] S6: The controller determines whether the cavity has reached the preset vacuum state time. If yes, proceed to step S7; otherwise, continue to maintain the vacuum state.

[0019] S7: The vacuum release component is controlled by the controller to release the vacuum in the containment cavity until the internal and external air pressures are equal;

[0020] S8: The vacuum chamber is opened by the vertical lifting and lowering movement of the movable plate, and the battery that has completed liquid aspiration is output to the next process.

[0021] The present invention also aims to provide a control method for a battery vacuum shroud liquid aspiration device, comprising the following steps:

[0022] S1: The vacuum cover is opened by the vertical lifting and lowering movement of the movable plate, and the liquid-absorbing battery is input into the liquid-absorbing part;

[0023] S2: Close the vacuum chamber by the vertical lifting and lowering movement of the movable plate;

[0024] S3: The vacuum assembly is controlled by the controller to evacuate the containment cavity within a preset time.

[0025] S4: Stop the vacuum assembly from working, and use the controller to control the vacuum release assembly to release the vacuum in the containment cavity until the internal and external atmospheric pressures are equal;

[0026] S5: Repeat steps S3-S4, and determine the number of executions through the controller. If the number of executions reaches the preset number, proceed to step S6; otherwise, continue execution.

[0027] S6: Control the vacuum assembly and deactivate the vacuum assembly to stop working via the controller;

[0028] S7: The vacuum chamber is opened by the vertical lifting and lowering movement of the movable plate, and the battery that has completed liquid aspiration is output to the next process.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention provides a battery vacuum liquid absorption device, which makes the structure of the entire vacuum cover flexible and versatile by setting at least one movable plate on the vacuum cover. Even when the vacuum cover is large in volume, it can still achieve a complete sealing function. At the same time, the movable plate and the fixed plate of the vacuum cover are designed separately, which facilitates processing, saves production costs, avoids deformation, and provides a good sealing effect, greatly improving the liquid absorption efficiency of the battery, thereby improving the production quality and service life of the battery.

[0031] 2. The sliding plate drives the movable side plate to move vertically upward along the sliding track and then moves towards the liquid absorption part, so that the movable side plates around the perimeter close to the center, which further improves the sealing effect of the vacuum cover and greatly improves the vacuum liquid absorption efficiency of the battery.

[0032] 3. Through the combined use of vacuum gauges, vacuum components, and de-vacuuming components, this battery vacuum liquid suction device can achieve intelligent vacuum control, monitor the vacuum level in real time, and adjust the vacuuming action according to the real-time vacuum level. The control is precise, and the vacuuming and de-vacuuming actions can be performed automatically and repeatedly according to production needs, without manual operation and supervision. This greatly improves the automation level of battery processing and the efficiency of battery liquid suction, and ensures the stability of battery liquid suction.

[0033] 4. By setting the first side plate and the second side plate relative to each other and setting the first side plate and the second side plate to be movably connected to the bottom plate and move up and down along the bottom plate, it is possible not only to control the vacuum cover to be in a closed or open state, flexibly realizing the liquid absorption and transportation of the battery, but also to control the automatic loading and unloading of the battery. The feeding to discharging is a linear movement, which greatly improves the battery transportation efficiency and significantly enhances the battery production efficiency.

[0034] 5. By setting a baffle flush with the groove on the movable side plate, the batteries can be loaded and unloaded smoothly, avoiding the batteries from being bumped or not transported smoothly due to the presence of the groove. The simple structure can ensure the smooth and efficient battery processing, and the whole device is highly practical.

[0035] 6. The movable top plate allows the vacuum cover to adapt to batteries of different heights. Only the movable top plates of different heights need to be manufactured to meet the working requirements of various batteries, which greatly improves the practicality of this device.

Detailed Implementation

[0046] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0048] like Figures 1 to 9 As shown, the present invention provides a battery vacuum liquid aspiration device, comprising: a base plate 100 for placing a battery tray, a vacuum cover 200 covering the base plate 100, and a receiving cavity 260 for vacuum liquid aspiration of the battery formed between the vacuum cover 200 and the base plate 100, wherein the vacuum cover 200 includes a side plate and a top plate connected to each other, and at least one side plate or the top plate is configured as a movable plate 210, and the opening or closing of the vacuum cover 200 is controlled by the vertical movement of the movable plate 210.

[0049] When the movable plate 210 is multi-faceted, the movable plate 210 includes a movable top plate 230 and at least one movable side plate 220, or multiple movable side plates 220.

[0050] The present invention provides a battery vacuum liquid suction device, which includes a vacuum cover 200 on a base plate 100 and at least one movable plate 210 on the vacuum cover 200. The movable plate 210 can move up and down in the vertical direction, and the opening or closing of the vacuum cover 200 is controlled by the up and down movement of the movable plate 210.

[0051] The movable plate 210 can be any side plate or top plate. When the movable plate 210 is a movable side plate 220, the opening or closing of the vacuum chamber 200 is controlled by the lifting and lowering movement of the movable side plate 220. In the initial state, the vacuum chamber 200 is open, and the battery to be absorbed is transported into the vacuum chamber 200. Then the movable side plate 220 rises until the vacuum chamber 200 is in a closed state. After the absorption is completed, the movable side plate 220 descends, the battery is output, and the processing of the next batch of batteries continues.

[0052] When the movable plate 210 is a movable top plate 230, the opening or closing of the vacuum cover 200 is controlled by the lifting and lowering movement of the movable top plate 230. In the initial state, the vacuum cover 200 is open, and the battery to be absorbed is transported into the vacuum cover 200. Then the movable top plate 230 is lowered to the connection point with the side plate of the vacuum cover 200, and the vacuum cover 200 is closed. After the absorption of liquid is completed, the movable top plate 230 is raised, the battery is output, and the processing of the next batch of batteries continues.

[0053] When the movable plate 210 consists of two movable side plates 220, these two movable side plates 220 can be arranged adjacently or oppositely. The other two side plates are fixed side plates 250. In the initial state, the vacuum cover 200 is in the open state, and the battery enters from the open position of the vacuum cover 200. The two movable side plates 220 rise until the vacuum cover 200 is in the closed state. After the battery absorbs liquid, the two movable side plates 220 descend, and the battery is output from the movable side plates 220 to continue the processing of the next batch of batteries.

[0054] When the movable plate 210 consists of a movable side plate 220 and a movable top plate 230, in the initial state, the vacuum cover 200 is in the open state, and the battery enters from the open part of the vacuum cover 200. The movable side plate 220 rises while the top plate descends until the vacuum cover 200 is in the closed state. After the battery absorbs liquid, the movable side plate 220 descends while the top plate rises, and the battery is output from the movable side plate 220 to continue the processing of the next batch of batteries.

[0055] When the movable plate 210 consists of two movable side plates 220 and one movable top plate 230, the two movable side plates 220 can be arranged adjacently or oppositely, while the other two side plates are fixed side plates 250. In the initial state, the vacuum cover 200 is in the open state, and the battery enters from the opening of the vacuum cover 200. The two movable side plates 220 rise while the movable top plate 230 descends until the vacuum cover 200 is in the closed state. After the battery absorbs liquid, the two movable side plates 220 descend while the movable top plate 230 rises, and the battery is output from the movable side plates 220 to continue the processing of the next batch of batteries.

[0056] When the movable plate 210 is a three-sided movable side plate 220, the other side plate is a fixed side plate 250. In the initial state, the vacuum cover 200 is in the open state, and the battery enters from the opening of the vacuum cover 200. The three-sided movable side plate 220 rises until the vacuum cover 200 is in the closed state. After the battery absorbs liquid, the three-sided movable side plate 220 descends, and the battery is output from the movable side plate 220 to continue the processing of the next batch of batteries.

[0057] Most existing vacuum shields 200 are one-piece designs, which achieve sealing and liquid absorption of the battery by raising and lowering the entire vacuum shield 200. However, one-piece vacuum shields 200 usually need to be cast or welded as a whole. When the vacuum shield 200 is large, it often greatly increases the processing difficulty and processing cost. At the same time, the large vacuum shield 200 is very easy to deform during production and transportation, resulting in poor sealing effect and affecting the liquid absorption efficiency of the battery. In addition, the one-piece vacuum shield 200 is heavy and not convenient for hoisting and use. In this embodiment, by providing at least one movable plate 210 on the vacuum cover 200, the structure of the entire vacuum cover 200 becomes flexible and versatile. Even when the vacuum cover 200 is large, it can still achieve a complete sealing function. At the same time, the movable plate 210 and the fixed plate of the vacuum cover 200 are designed separately, which facilitates processing, saves production costs, avoids deformation, and provides a good sealing effect. In addition, the weight of the entire vacuum cover 200 is distributed to each plate, which facilitates transportation and hoisting, greatly improves the installation efficiency of the vacuum cover 200 and the liquid absorption efficiency of the battery, thereby improving the production quality and service life of the battery.

[0058] Preferably, such as Figures 1 to 9 As shown, the base plate 100 has a groove 110 for the movable side plate 220 to move in the vertical direction. The opening or closing of the vacuum hood 200 is controlled by the lifting and lowering movement of the movable side plate 220 within the groove 110.

[0059] More preferably, the bottom plate 100 is provided with a liquid absorption part 130 located in the receiving cavity 260 in the middle, wherein the movable side plate 220 moves along the liquid absorption part 130 when it moves vertically upward in the groove 110, or the movable side plate 220 moves along the liquid absorption part 130 after it moves vertically upward in the groove 110.

[0060] In this embodiment, when the movable plate 210 is the movable side plate 220, the base plate 100 is provided with a groove 110 for the movable side plate 220 to move up and down. In the initial position, the movable side plate 220 is located below the base plate 100. When it is necessary to close the vacuum cover 200, the movable side plate 220 rises and moves towards the liquid absorption part 130 during the rising process. That is, the movable side plate 220 moves up and closes at the same time, or the movable side plate 220 moves upward first and then closes along the liquid absorption part 130, so that the movable side plate 220 can further abut against the base plate 100 and control the vacuum cover 200 to achieve a seal. After the liquid absorption is completed, the movable side plate 220 descends and moves away from the liquid absorption part 130, controlling the vacuum cover 200 to be fully open, which facilitates the loading and unloading of batteries.

[0061] Preferably, such as Figures 1 to 9 As shown, a sliding assembly 300 is installed at the bottom of the base plate 100. The sliding assembly 300 includes a sliding plate 310 and a sliding track 320. The sliding plate 310 is connected to the movable side plate 220. The movement of the sliding plate 310 within the sliding track 320 controls the movable side plate 220 to move vertically upward and then move along the path close to the liquid absorption part 130.

[0062] More preferably, a movable cylinder is connected to the sliding component 300, and the movement of the sliding component 300 is controlled by the movable cylinder.

[0063] In this embodiment, the sliding assembly 300 is installed on the movable side plate 220. Each movable side plate 220 has a sliding assembly 300 installed on both sides. The sliding assembly 300 is also connected to a movable cylinder. The sliding assembly 300 includes a sliding plate 310 and an L-shaped sliding track 320. The sliding track 320 includes a vertical part 321 and a horizontal part 322. When the movable side plate 220 needs to move upward, the movable cylinder controls the sliding plate 310 to drive the movable side plate 220 to move upward along the vertical part 321 first, and then move along the horizontal part 322 toward the liquid absorption part 130. This achieves the effect of the movable side plates 220 closing towards the center, further improving the sealing effect of the vacuum cover 200 and greatly improving the battery vacuum liquid absorption efficiency.

[0064] Preferably, such as Figures 1 to 9 As shown, a baffle 221 adapted to the groove 110 is installed on one side of the movable side plate 220. When the battery is in the loading and unloading state, the baffle 221 is engaged with the groove 110.

[0065] In this embodiment, the width of the groove 110 is greater than the width of the movable side plate 220, which facilitates the free movement of the movable side plate 220 within the groove 110. One end of the movable side plate 220 is provided with a baffle 221 corresponding to the groove 110. Before each operation, the end of the movable side plate 220 with the baffle 221 engages with the base plate 100, i.e., engages with the groove 110, making the base plate 100 flat and seamless. Similarly, after the liquid absorption is completed, the baffle 221 will continue to retract to the engagement point with the groove 110, i.e., the baffle 221 is flush with the base plate 100, so that the batteries can be loaded and unloaded smoothly, avoiding the batteries from being bumped or hindered in transportation due to the presence of the groove 110. The simple structure can ensure the smooth and efficient operation of the battery processing, and the entire device is highly practical.

[0066] Preferably, such as Figures 1 to 9 As shown, the movable side panel 220 includes two side panels arranged opposite to each other.

[0067] More preferably, the base plate 100 includes a feeding section 120, a liquid absorption section 130 and a discharging section 140 arranged sequentially, wherein a first side plate 222 is provided at the connection between the feeding section 120 and the liquid absorption section 130, and a second side plate 223 is provided at the connection between the liquid absorption section 130 and the discharging section 140.

[0068] In this embodiment, the battery moves along the base plate 100, which is sequentially provided with a feeding section 120, a liquid absorption section 130, and a discharging section 140. The battery is fed into the liquid absorption section 130 through the feeding section 120 and discharged through the discharging section 140 after liquid absorption is completed. In this embodiment, two movable side plates 220 are arranged opposite to each other on the vacuum chamber 200, namely a first side plate 222 and a second side plate 223. The first side plate 222 and the second side plate 223 control the feeding and discharging of the battery, respectively. The opening and closing of the vacuum chamber 200 is controlled by the lifting and lowering movement of the first side plate 222 and the second side plate 223 on the base plate 100. Initially, the vacuum chamber 200 is open, and the battery is fed into the liquid absorption section 130 by the feeding section 120. Then, the first side plate 222 and the second side plate 223 move upward until the vacuum chamber 200 is closed. After the battery has absorbed the liquid, the first side plate 222 and the second side plate 223 move downward, the vacuum chamber 200 opens, and the battery is fed from the liquid absorption section 130 to the discharge section 140 for discharge. In this embodiment, the first side plate 222 and the second side plate 223 are two movable side plates 220 oppositely arranged on the vacuum chamber 200. By setting the first side plate 222 and the second side plate 223 to be movably engaged with the base plate 100 and to move up and down along the base plate 100, it is possible not only to control the vacuum chamber 200 to be in a closed or open state, flexibly realizing the liquid absorption and transportation of the battery, but also to control the automatic loading and unloading of the battery. The feeding to discharge is a linear movement, resulting in high battery transportation efficiency and greatly improving battery production efficiency.

[0069] Preferably, such as Figures 1 to 9 As shown, when the movable plate 210 includes the movable top plate 230, the opening or closing of the vacuum hood 200 is controlled by the vertical lifting and lowering movement of the movable top plate 230.

[0070] In this embodiment, the movable plate 210 can also be a movable top plate 230. The movable top plate 230 is driven to move vertically up and down by an external cylinder (not shown in the figure). The movable top plate 230 can be used alone as the movable plate 210 to close and open the vacuum cover 200. Preferably, the vacuum cover 200 is closed or opened by a combination of the movable top plate 230 and the movable side plate 220. In actual operation, the movable side plate 220 is used to close the vacuum cover 200 in the horizontal direction, and the movable top plate 230 is used to close the vacuum cover 200 in the vertical direction. While working independently, they also work together. The arrangement of multiple movable plates 210 makes the entire vacuum cover 200 mechanism flexible and versatile, highly operable, and greatly reduces the processing difficulty of the vacuum cover 200. Only each movable plate 210 needs to be processed separately, and then the movable side plate 220 can be controlled by an external power source to perform sealing cooperation. Furthermore, the movable top plate 230 allows the vacuum cover 200 to accommodate batteries of different heights. Only the movable top plate 230 of varying heights needs to be fabricated to meet the operational requirements of various batteries, greatly enhancing the practicality of the device. Additionally, the power sources for each movable side plate 220 and the movable top plate 230 are independent of each other. This independent power source ensures that the movement of each movable plate 210 does not interfere with each other, allowing for independent movement to the connection points, and the movement process is flexible and adjustable.

[0071] Preferably, such as Figures 1 to 9 As shown, the bottom of the liquid suction section 130 is connected to a vacuum assembly 400 for evacuating the liquid suction section 130 and a vacuum release assembly 500 for releasing the vacuum. The bottom of the liquid suction section 130 is also connected to a vacuum gauge 510 for detecting the vacuum level information of the liquid suction section 130. The vacuum assembly 400 and the vacuum release assembly 500 perform evacuation and vacuum release based on the vacuum level information obtained by the vacuum gauge 510.

[0072] In this embodiment, a vacuum gauge 510, a vacuum assembly 400, and a vacuum release assembly 500 are also connected to the bottom of the base plate 100. The vacuum gauge 510, vacuum assembly 400, and vacuum release assembly 500 are all controlled by a controller (not shown in the figure). The vacuum gauge 510, vacuum assembly 400, and vacuum release assembly 500 are all connected to the receiving cavity 260. The vacuum assembly 400 includes an inlet end 410 and an outlet end 420. A solenoid valve and a ball valve are connected between the inlet end 410 and the outlet end 420. The inlet end 410 is connected to the receiving cavity 260, and the outlet end 420 is connected to an external vacuum pump. The controller controls the opening and closing of the solenoid valve, which in turn controls the opening and closing of the ball valve, ultimately controlling whether the vacuum assembly 400 evacuates the receiving cavity 260. During the working period, the vacuum pump is always in working condition. The evacuation of the receiving cavity 260 is controlled by controlling the opening and closing of the vacuum assembly 400. The vacuum release assembly 500 also includes a solenoid valve and a ball valve. After a preset vacuum time is reached, the controller controls the opening and closing of the solenoid valve, which in turn controls the opening and closing of the ball valve, ultimately releasing the vacuum from the containment cavity 260. Specifically, when the battery to be absorbed is transported into the absorption section 130, the movable side plate 220 or the movable top plate 230 moves up and down, causing the vacuum cover 200 to be in a closed state. The controller controls the vacuum assembly 400 to start working, evacuating the containment cavity 260. At the same time, the vacuum gauge 510 monitors the real-time vacuum level in the containment cavity 260. When the real-time vacuum level reaches the preset vacuum level, the controller controls the vacuum assembly 400 to close, stopping the evacuation. Then, the vacuum state is maintained for a preset time. After the preset vacuum state time is reached, the controller controls the vacuum release assembly 500 to start working, releasing the vacuum from the containment cavity 260 until the internal and external atmospheric pressures are equal. Then, the vacuum cover 200 is opened by the movement of the movable side plate 220 or the movable top plate 230, and the battery after absorption is output to the next process. Existing vacuum liquid aspiration devices mostly employ a timed vacuuming method, where a vacuum pump evacuates the receiving cavity 260 for a fixed period, stopping the vacuuming process after the set time. Similarly, the vacuum is released after a certain time. This method of vacuuming is extremely inaccurate in controlling the vacuum level within the receiving cavity 260, making it impossible to know the true vacuum level and adjust the vacuum level according to actual production needs. It is extremely inconvenient to use and affects the battery liquid aspiration efficiency, leading to unstable or substandard battery liquid aspiration efficiency. In this embodiment, however, through the coordinated use of the vacuum gauge 510, vacuum assembly 400, and vacuum release assembly 500, the battery vacuum liquid aspiration device can achieve intelligent vacuum control. It monitors the vacuum level in real time and adjusts the vacuuming action based on the real-time vacuum level, providing precise control. It can automatically and repeatedly perform vacuuming and vacuum release actions according to production needs, without manual operation or supervision, greatly improving the automation level of battery processing and battery liquid aspiration efficiency, and ensuring the stability of battery liquid aspiration.

[0073] Preferably, such as Figures 1 to 9 As shown, the vacuum hood 200 includes a fixed side plate 250, on which a limiting step 251 for limiting the movable side plate 220 and a limiting surface 252 for limiting the movable top plate 230 are provided.

[0074] In this embodiment, the vacuum chamber 200 also includes a fixed side plate 250. The fixed side plate 250 allows batteries to be loaded and unloaded along a fixed route, controlling the loading and unloading direction of the batteries and preventing deviations in the battery transport route from affecting production efficiency and processing quality. Additionally, the fixed side plate 250 is provided with a limiting step 251. The movable side plate 220 stops moving when it rises to engage with the limiting step 251, ensuring the relative position between the movable side plate 220 and the movable top plate 230. This ensures the sealing of the vacuum chamber 200 while preventing interference between the movable side plate 220 and the movable top plate 230, which could lead to poor assembly of the vacuum chamber 200. Furthermore, the fixed side plate 250 is also provided with a limiting surface 252 for limiting the movable top plate 230. When the movable top plate 230 descends, it stops descending when it contacts the limiting surface 252, allowing for precise positioning of the movement trajectory of the movable top plate 230, ensuring accuracy and reliability.

[0075] Preferably, such as Figures 1 to 9 As shown, a sealing strip 240 is installed at the connection between the movable side plate 220 and the movable top plate 230.

[0076] More preferably, the movable side plate 220 is provided with a limiting block 224 that engages with the base plate 100.

[0077] In this embodiment, a sealing strip 240 is provided at the connection between the movable side plate 220 and the movable top plate 230. The sealing strip 240 further ensures the sealing performance of the vacuum cover 200, so that the vacuum cover 200 can maintain a vacuum state after air is extracted, thereby improving the liquid absorption efficiency of the battery and ensuring the battery processing quality. In addition, a limit block 224 is also provided on the movable side plate 220. The movable side plate 220 stops rising when it reaches the limit block 224 and engages with the bottom plate 100. This can control the movement process of the movable side plate 220 and ensure the stability and accuracy of its movement.

[0078] The working principle of the battery vacuum liquid suction device provided by the present invention is as follows: In the initial state, the first side plate 222 and the second side plate 223 are located below the bottom plate 100 and are engaged with the bottom plate 100 through the baffle 221. The movable top plate 230 is opened, and the entire vacuum cover 200 is in an open state. At this time, batteries are fed in, and a certain number of batteries enter the liquid suction section 130 from the feeding section 120. After all the batteries have entered the liquid suction section 130, the first side plate 222 and the second side plate 223 rise along the groove 110 under the action of the movable cylinder and the sliding assembly 300, and move towards the liquid suction section 130. The movable top plate 230 also descends to the connection point with the first side plate 222 and the second side plate 223 under the action of the external cylinder. The combined action ensures that the vacuum chamber 200 is sealed. The controller controls the vacuum component 400 to start working, evacuating the containment cavity 260. Simultaneously, the vacuum gauge 510 monitors the real-time vacuum level inside the containment cavity 260. When the real-time vacuum level reaches the preset vacuum level, the controller controls the vacuum component 400 to shut down and stop evacuating. The vacuum state is then maintained for a preset time. After the preset vacuum state time is reached, the controller controls the vacuum release component 500 to start working, releasing the vacuum in the containment cavity 260 until the internal and external atmospheric pressures are equal. Then, the movable top plate 230 rises, and the movable side plate 220 descends to be flush with the bottom plate 100, opening the vacuum chamber 200. The next batch of batteries is pushed into the vacuum chamber 200, while the batteries that have completed liquid absorption are pushed out to the discharge section 140 for discharge, thus achieving reciprocating motion.
