Description

Technical Field

[0001] The invention relates to the technical field of battery manufacturing, in particular to a quantitative acid extraction device for a lead-acid battery. Background Art

[0002] In the process of manufacturing batteries, once the battery pack is placed in the battery slot and the battery cover is installed, the next step is the acidification process. During this process, a certain amount of acid needs to be injected into the battery in excess of the normal level to ensure that the active materials inside the battery can fully react chemically and activate the battery. After the formation process is completed, in order to optimize the battery performance and avoid corrosion or damage caused by excessive acid, the excess acid in the battery must be sucked out.

[0003] Acid formation is one of the key steps in battery manufacturing. It not only affects the initial performance of the battery, but also determines the long-term reliability and safety of the battery. Injecting excess acid helps to ensure that the acid is evenly distributed between the battery plates and between the plate grids, which is a prerequisite for the full reaction of the active substances inside the battery. However, once the formation process is completed, if there is excess acid remaining inside the battery, it may cause the battery to self-discharge faster, and may corrode the battery structure in the long term, affecting its performance and life. For this reason, battery manufacturers use special acid suction equipment to remove this excess acid. This step requires precise control to ensure that the right amount of acid is sucked out of each battery cell to avoid affecting the performance of the battery due to insufficient acid inside.

[0004] Lead-acid batteries used in electric vehicles are generally four or five batteries connected in series. Any battery in the battery will affect the consistency of the entire battery pack. However, each battery is composed of six cells connected in series. The saturation of each cell directly affects the consistency of the entire battery pack, causing a single battery in the entire battery pack to lag behind, affecting the service life of the entire battery pack. Therefore, it is necessary to ensure that the acid content of each cell of the battery is consistent during the acid extraction process.

[0005] Existing acid extraction devices all focus on whether they can completely extract the residual acid inside the battery. For example, the Chinese utility patent with the authorization announcement number: CN202020438576.7 discloses "a battery acid extraction device", including multiple single-cell acid extraction tubes with one end deep into the battery during use, and also including a holding tube, one end of the holding tube is provided with a connector for an external air extraction device, and the holding tube is provided with a plurality of inner cavities connected to the holding tube. The buffer sleeve is provided with a connecting tube at one end, and one end of the connecting tube is connected to the holding tube, and the other end extends into the inner cavity of the buffer sleeve. The inner cavity of the buffer sleeve is provided with an active tube that can slide along the inner cavity of the buffer sleeve, and one end of the active tube is connected to the connecting tube through a hose, and the other end is provided with the single-cell acid extraction tube. When the internal structure of the battery is uneven, the utility model can automatically correct the insertion depth to ensure that the residual acid inside the single cell is completely extracted. However, it is impossible to accurately control the amount of residual acid in the single cell, that is, it is impossible to ensure the consistency of the battery. Summary of the invention

[0006] In response to the problem that the acid extraction device in the prior art mentioned in the background technology cannot accurately control the amount of residual acid in a single cell, that is, it cannot ensure the consistency of the battery, the present application provides a quantitative acid extraction device for a lead-acid battery, which adopts a deformable base and a telescopic rod to achieve the high storage of the mobile phone holder, while ensuring that the charging function can be operated in both the storage state and the unfolded state, so as to facilitate users to carry and use it outdoors.

[0007] In order to achieve the above-mentioned purpose, a quantitative acid extraction device for a lead-acid battery is disclosed, comprising a single-cell acid extraction tube corresponding to each single-cell battery of the lead-acid battery, wherein the single-cell acid extraction tube is provided with a control unit; wherein a signal transmission body is sleeved on the single-cell acid extraction tube, and the position of the signal transmission body is set according to the liquid level height of the remaining acid; wherein a buoy is movably provided on the single-cell acid extraction tube, and when the buoy touches the signal transmission body, the control unit blocks the single-cell acid extraction tube.

[0008] The single-cell acid extraction tube is equipped with a signal transmission body and a float, which can adjust its position according to the liquid level of the remaining acid. When the float touches the signal transmission body, the control unit automatically blocks the single-cell acid extraction tube, thereby stopping the acid extraction operation. This automated control process optimizes the acid management in lead-acid batteries, ensuring that the acid extraction work makes the acid content in each cell of the battery consistent by accurately controlling the acid content in each cell. This automated device significantly improves the efficiency and accuracy of the operation, reduces the possibility of human error, and thus achieves higher economic benefits and work efficiency.

[0009] Furthermore, the control unit includes a housing and a sealing plate arranged in the housing, and a brake device connected to the sealing plate is arranged on the housing, and the brake device controls the sealing plate to rotate in the housing. The sealing plate can rotate in the housing to adjust the open or closed state of the single-grid acid extraction tube. The design of the brake device allows the acid extraction process to be accurately controlled. When the set acid amount is reached, the brake device will quickly act on the sealing plate to achieve the immediate closure of the single-grid acid extraction tube to prevent excessive acid extraction. This solution can accurately control the acid extraction process and ensure the safety and repeatability of the treatment process. This mechanized and automated control greatly reduces the complexity of operation and human errors, not only simplifies the equipment structure, but also improves the accuracy and response speed of operation through automatic control technology, and improves the overall reliability and efficiency of the system.

[0010] Preferably, the braking device includes a circulation gear and a blocking gear, and a sealing ring is provided on the inner wall of the control unit housing at the position of the sealing plate under the blocking gear. When the sealing plate is turned to the blocking gear, the sealing ring can effectively close the acid extraction channel and prevent the acid from continuing to flow out, thereby accurately controlling the acid amount to a preset safety level. The application of the sealing ring ensures that there is no leakage during the acid extraction process and improves the safety of the system; by automatically switching the circulation and blocking gears, the operation is more convenient and the error rate is low, which significantly improves the service life and maintenance efficiency of the equipment. Not only does it enhance the practicability of the equipment, but it also improves the accuracy and convenience of the operation through automation, effectively solving the error and leakage problems that are prone to occur in traditional manual adjustment.

[0011] Preferably, the braking device comprises a micro motor; a rotating shaft is arranged in the middle of the sealing plate, and the micro motor is connected to the rotating shaft; when the buoy does not touch the signal transmission body, the braking device is in the circulation gear. The micro motor can accurately control the position of the sealing plate, thereby realizing the rapid switching of the switch state of the single-cell acid extraction tube. When the buoy does not touch the signal transmission body, the braking device remains in the circulation gear, allowing the acid to flow; once the buoy triggers the signal transmission body, the micro motor drives the sealing plate to turn to the blocking gear, and immediately stops the flow of acid. This effectively avoids the damage that may be caused by excessive extraction of battery acid. This automated and electric control system significantly improves the reliability and efficiency of operation. The use of a micro motor to automatically switch the position of the sealing plate simplifies the mechanical complexity, while improving the overall response speed and operation accuracy of the system.

[0012] Preferably, the signal transmission body includes a clamp and a sensor arranged on the clamp, and the sensor is arranged on the side of the clamp close to the buoy. The sensor is located on the side of the clamp close to the buoy, and can accurately detect the position of the buoy and the change of the acid level, thereby triggering the closing of the single-cell acid extraction tube. The precise configuration of the sensor enables the entire system to respond more sensitively to the change of the acid level, adjust the acid extraction process in real time, and ensure that the amount of acid in each cell is maintained in the optimal state. This solution achieves more detailed control and monitoring through sensors, thereby improving the accuracy and reliability of the entire system. The application of sensor layout and real-time monitoring technology not only improves the accuracy of operation, but also enables the equipment to automatically adapt to various working environments and conditions. Even when the internal structure of the battery is uneven, quantitative acid extraction can be carried out by inserting the single-cell acid extraction tube into the bottom of the single-cell battery, which enhances the versatility and practicality of the equipment.

[0013] Furthermore, it includes a fixed frame, on which a plurality of single-cell acid extraction tubes are arranged in parallel, and the single-cell acid extraction tubes on the fixed frame can synchronously perform quantitative acid extraction of the lead-acid battery. Normally, a 12-volt lead-acid battery is composed of 6 2-volt single cells connected in series. This is because the voltage of each single cell is about 2 volts when fully charged, and six single cells connected in series can provide a voltage of about 12 volts, which is the standard voltage of most electric vehicle electrical systems. Therefore, the key to this solution is to achieve the coordinated work of multiple single-cell acid extraction tubes, thereby improving the working efficiency of the entire system, especially in the entire lead-acid battery, it can ensure the consistency of the acid amount of all single cells. Compared with the operation of a single single-cell acid extraction tube, this synchronous operation significantly reduces working time and labor intensity, and improves overall work efficiency and safety. This not only optimizes the workflow, but also improves the stability and reliability of the equipment through integrated design.

[0014] Preferably, the single-cell acid extraction tubes placed on the fixed frame have the same specifications, and the control unit arranged on each single-cell acid extraction tube operates independently. Each single-cell acid extraction tube can operate independently, and while keeping the overall operation synchronized, it can also accurately control a single battery cell. This independent but unified control strategy helps to solve the problem of inconsistent battery performance that may be caused by cell differences in the battery pack. It can ensure that the processing effect of each unit remains consistent when performing large-scale battery acid extraction operations, while being able to make independent adjustments for specific batteries, so that large battery packs can be managed and maintained more effectively, and the overall performance and life of the battery pack are improved. Combining the standardization of single-cell acid extraction tubes with the independent operation of the control unit not only improves the flexibility and adaptability of the system, but also enhances the processing capability of the equipment when facing complex or unevenly aged battery packs, thereby ensuring efficient and balanced maintenance operations.

[0015] Preferably, the fixing frame includes two fixing plates arranged in parallel, the two fixing plates are provided with corresponding through holes, a connector is provided between the two fixing plates, and the two fixing plates are relatively fixed. This solution enhances the stability of the fixing frame and the alignment accuracy of the single-cell acid extraction tube, ensures the accuracy and safety during the operation, and is used for maintaining and operating multi-unit lead-acid batteries. By optimizing the design of the fixing frame, not only the durability of the entire device is enhanced, but also the consistency and repeatability of the operation are guaranteed.

[0016] Therefore, the present invention has the following beneficial effects:

[0017] (1) Precise control of acid volume: This device automatically monitors and adjusts the acid volume in a single cell to ensure uniform acid volume in each battery cell, thereby optimizing the performance and consistency of the entire battery pack, improving battery efficiency and power output stability.

[0018] (2) Automated operation improves safety and efficiency: The automated control system replaces manual monitoring and adjustment, which reduces human errors and improves the safety and efficiency of operations. The automated acid extraction process reduces the labor intensity of operators and improves the speed and accuracy of maintenance operations.

[0019] (3) Extending battery life: By maintaining the acid content of each battery cell at an optimal level, damage caused by overcharging and discharging of the battery and imbalance of acid content is effectively prevented, thereby significantly extending the battery life and overall economic benefits.

[0020] (4) Enhanced system adaptability and scalability: The design of the device takes into account the scalability of the system. For example, a temperature monitoring module and remote control function can be added to enhance the system's adaptability to different operating environments and provide possibilities for future technology upgrades and functional expansion.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] like Figure 1 , 2 As shown in Figure 4, a quantitative acid extraction device for a lead-acid battery comprises a single-cell acid extraction tube 9 corresponding to each single cell of the lead-acid battery, and a control unit 1 is arranged on the single-cell acid extraction tube 9; wherein, a signal transmission body 6 is sleeved on the single-cell acid extraction tube 9, and the position of the signal transmission body 6 is set according to the liquid level of the remaining acid; wherein, a buoy 8 is movably arranged on the single-cell acid extraction tube 9, and when the buoy 8 touches the signal transmission body 6, the control unit 1 blocks the single-cell acid extraction tube 9. The single-cell acid extraction tube 9 is equipped with a signal transmission body 6 and a buoy 8, and can adjust its position according to the liquid level of the remaining acid. When the buoy 8 touches the signal transmission body 6, the control unit 1 automatically blocks the single-cell acid extraction tube 9, thereby stopping the acid extraction operation. This automated control process optimizes the acid management in the lead-acid battery, and ensures that the acid extraction work makes the acid amount in each single cell of the battery consistent by accurately controlling the acid amount in each single cell. This automated device significantly improves the efficiency and accuracy of the operation, reduces the possibility of human error, and thus achieves higher economic benefits and work efficiency.

[0032] like Figure 3 , 5 As shown, the control unit 1 includes a housing 3 and a sealing plate 5 disposed in the housing 3. The housing 3 is provided with a brake device 2 connected to the sealing plate 5. The brake device 2 controls the sealing plate 5 to rotate in the housing 3. The brake device 2 includes a flow gear and a blocking gear. A sealing ring 4 is provided on the inner wall of the housing 3 of the control unit 1 at a position corresponding to the sealing plate 5 under the blocking gear. The brake device 2 includes a micro motor; a rotating shaft 51 is provided in the middle of the sealing plate 5, and the micro motor is connected to the rotating shaft 51; when the buoy 8 does not touch the signal transmission body 6, the brake device 2 is in the flow gear.

[0033] The sealing plate 5 can rotate in the housing 3 to adjust the open or closed state of the single-grid acid extraction tube 9. The design of the brake device 2 allows the acid extraction process to be precisely controlled. When the set amount of acid is reached, the brake device 2 will quickly act on the sealing plate 5 to achieve the immediate closure of the single-grid acid extraction tube 9 to prevent excessive acid extraction. This solution can accurately control the acid extraction process and ensure the safety and repeatability of the treatment process. This mechanized and automated control greatly reduces the complexity of operation and human errors, not only simplifies the equipment structure, but also improves the accuracy and response speed of operation through automatic control technology, and improves the overall reliability and efficiency of the system. When the sealing plate 5 is turned to the blocking position, that is, the horizontal horizontal state, the sealing ring 4 can effectively close the acid extraction channel and prevent the acid from continuing to flow out, thereby accurately controlling the acid amount to a preset safety level. The application of the sealing ring 4 ensures that there is no leakage during the acid extraction process and improves the safety of the system; by automatically switching the circulation and blocking positions, the operation is more convenient and the error rate is low, which significantly improves the service life and maintenance efficiency of the equipment. It not only enhances the practicability of the equipment, but also improves the accuracy and convenience of operation through automation, effectively solving the error and leakage problems that are easy to occur in traditional manual adjustment. The micro motor can accurately control the position of the sealing plate 5, thereby realizing the rapid switching of the switch state of the single-grid acid extraction tube 9. When the buoy 8 does not touch the signal transmission body 6, the brake device 2 remains in the flow gear, allowing the acid to flow; once the buoy 8 triggers the signal transmission body 6, the micro motor drives the sealing plate 5 to turn to the blocking gear, and immediately stops the flow of acid. This effectively avoids the damage that may be caused by excessive extraction of battery acid. This automated and electric control system significantly improves the reliability and efficiency of operation. The use of a micro motor to automatically switch the position of the sealing plate 5 simplifies the mechanical complexity and improves the overall response speed and operation accuracy of the system.

[0034] The signal transmission body 6 includes a clamp 7 and a sensor 61 arranged on the clamp 7. The sensor 61 is arranged on the side of the clamp 7 close to the buoy 8. The sensor 61 is fixed on the single-cell acid extraction tube 9 through the clamp 7. The sensor 61 is located on the side of the clamp 7 close to the buoy 8, and can accurately detect the position of the buoy 8 and the change of the acid liquid level, thereby triggering the closing of the single-cell acid extraction tube 9. The precise configuration of the sensor 61 enables the entire system to respond more sensitively to the change of the acid liquid level, adjust the acid extraction process in real time, and ensure that the amount of acid in each cell is maintained in the optimal state. This solution achieves more detailed control and monitoring through the sensor 61, thereby improving the accuracy and reliability of the entire system. The application of the sensor 61 layout and real-time monitoring technology not only improves the accuracy of the operation, but also enables the equipment to automatically adapt to various working environments and conditions. Even when the internal structure of the battery is uneven, quantitative acid extraction can be performed by inserting the single-cell acid extraction tube 9 to the bottom of the single-cell battery, thereby enhancing the versatility and practicality of the equipment.

[0035] like Figure 6 , 7 As shown, in this embodiment, six single-cell acid extraction tubes 9 are arranged in parallel on the fixing frame 10, and the single-cell acid extraction tubes 9 on the fixing frame 10 can simultaneously perform quantitative acid extraction of the lead-acid battery. The single-cell acid extraction tubes 9 placed on the fixing frame 10 have the same specifications, and the control unit 1 set on each single-cell acid extraction tube 9 operates independently. The fixing frame 10 includes two fixed plates 11 arranged in parallel, and the two fixed plates 11 are correspondingly provided with through holes 12. A connector 13 is arranged between the two fixed plates 11. The two fixed plates 11 are relatively fixed, and the two fixed plates and the connector can be disassembled and assembled at will, which is convenient for cleaning or storage.

[0036] Normally, a twelve-volt lead-acid battery is composed of six two-volt single cells connected in series. This is because the voltage of each single cell is about two volts when fully charged, and six single cells connected in series can provide a voltage of about twelve volts, which is the standard voltage of most electric vehicle electrical systems. Therefore, the key to this solution is to achieve the coordinated work of multiple single-cell acid extraction tubes 9, improve the working efficiency of the entire system, especially in the entire lead-acid battery, to ensure the consistency of the acid content of all single cells. Compared with the operation of a single single-cell acid extraction tube 9, this synchronous operation significantly reduces working time and labor intensity, and improves overall work efficiency and safety. This not only optimizes the workflow, but also improves the stability and reliability of the equipment through an integrated design. Each single-cell acid extraction tube 9 can operate independently, while keeping the overall operation synchronized, it can also accurately control a single battery cell. This independent but unified control strategy helps to solve the problem of inconsistent battery performance that may be caused by cell differences in the battery pack. It can ensure that the processing effect of each unit is consistent when performing large-scale battery acid extraction operations, and at the same time, it can be adjusted independently for specific batteries, so that large battery packs can be managed and maintained more effectively, and the overall performance and life of the battery pack can be improved. Combining the standardization of the single-cell acid extraction pipe 9 with the independent operation of the control unit 1 not only improves the flexibility and adaptability of the system, but also enhances the equipment's ability to handle complex or unevenly aged battery packs, thereby ensuring efficient and balanced maintenance operations. By optimizing the design of the fixing frame 10, not only is the durability of the entire device enhanced, but the consistency and repeatability of the operation are also guaranteed.

[0037] The quantitative acid extraction device of the lead-acid battery disclosed in this embodiment is intended to solve the problem of inconsistent acid content between battery cells in the prior art, which often leads to reduced performance and shortened service life of the battery pack. In applications such as electric vehicles, the lead-acid battery is composed of a plurality of cells connected in series, and the uneven acid content between the cells can seriously affect the performance and life of the entire battery pack. Therefore, the present invention provides a device that can accurately control the acid content of each cell, and by ensuring the uniformity of the acid content of each cell, the operating efficiency and life of the entire battery pack are improved.

[0038] The core components of the quantitative acid extraction device include a control unit 1, a signal transmission component, and an acid extraction device. The specific operation is to monitor and adjust the working state of the acid extraction device through the signal transmission component through the instructions of the control unit 1. The acid extraction device directly extracts the residual acid through the single-cell acid extraction tube 9 set in each battery cell, wherein the operation of each single-cell acid extraction tube 9 is independently controlled by the control unit 1, ensuring the accuracy and reliability of the operation. In the specific implementation of the acid extraction operation, the single-cell acid extraction tube 9 is installed above the filter mesh of the battery cell, and the residual acid located above the filter mesh can be extracted under the action of negative pressure. The fixing device is used to calibrate and fix the position of the single-cell acid extraction tube 9 to ensure stability and repeatability during the acid extraction process. A buoy 8 is installed on the top of the single-cell acid extraction tube 9, and the design of the buoy 8 allows it to float up and down according to the change of the liquid level. A signal transmission device is provided on the buoy 8. Once the buoy 8 reaches the set acid liquid level, it will touch the signal transmission device and trigger the signal transmitted to the control unit 1.

[0039] After receiving the signal, the control unit 1 instructs the brake device 2 to start. The brake device 2 is composed of a signal receiver and a rotating motor. After receiving the signal, the rotating motor is driven to adjust the state of the sealing device. The state of the sealing device changes from open to closed. At the same time, the sealing ring 4 will also be completely closed, thereby blocking the acid extraction process. The accuracy of this series of operations ensures that the residual acid in each cell is maintained at an optimal level, thereby ensuring the consistency and performance of the battery pack.

[0040] In this solution, the signal transmission body 6 and the buoy 8 are used in combination, and their interaction ensures the timeliness and accuracy of the acid extraction operation. By setting the interaction threshold between the buoy 8 and the signal transmission body 6, the device can dynamically adjust the acid extraction operation according to the actual acid consumption, ensuring that the acid amount of each single cell is always maintained at the set state.

[0041] In this embodiment, in the application of lead-acid batteries, especially the battery pack used in electric vehicles, the performance and life of each battery play a decisive role in the reliability and efficiency of the entire battery pack. Each battery is usually composed of a plurality of cells connected in series. The uneven performance of a single cell will lead to a decrease in the performance of the entire battery, thereby affecting the service life and efficiency of the entire battery pack. In order to solve this problem, the present invention provides a quantitative acid extraction device for lead-acid batteries, which can accurately control and adjust the amount of residual acid in each cell, so as to ensure the uniformity between battery cells and the performance consistency of the entire battery pack.

[0042] The operation and use method of the quantitative acid extraction device is as follows: first, a single-cell acid extraction tube 9 is installed in each cell of the lead-acid storage battery. These single-cell acid extraction tubes 9 directly contact the filter mesh of the battery cell, and extract the residual acid on the upper part of the filter mesh by the negative pressure principle. In order to ensure the fixation and stability of the single-cell acid extraction tube 9, a fixing device is used to calibrate and lock the position of the single-cell acid extraction tube 9 to ensure the continuity and reliability of the acid extraction process.

[0043] In the middle of the single-cell acid extraction tube 9, a buoy 8 with a larger ring than the single-cell acid extraction tube 9 is installed, so that the buoy 8 can float up and down in the acid solution, and the change of its position can accurately reflect the height of the acid solution level. In order to limit the specific height of acid extraction, a snap device is provided, which is used to fix the signal transmission device, and the buoy 8 is located above the fixed signal transmission device. When the residual acid inside the battery is extracted to a height lower than the set limit, the buoy 8 will drop and touch the signal transmission device. At this time, the signal transmission device will be activated and send a signal to the brake device 2, which is composed of a signal receiver and a rotating motor. After receiving the signal, the rotating motor will start and drive the closing device to adjust from an open state to a closed state. At the same time, the sealing ring 4 is completely closed with the closing device, thereby effectively blocking the acid extraction and ensuring that the amount of acid in each single cell is accurately controlled at an optimal level. During the operation, it is particularly important to pay attention to the accuracy and timeliness of signal transmission. Any delayed or erroneous signal may cause the acid solution to be over-extracted or not extracted in time, which will directly affect the performance and life of the battery. Therefore, the signal transmission device and its connection and response speed with the control unit 1 are the key to the design of the entire system, and 5G technology can be used to ensure responsiveness. In addition, the mechanical components of the entire device, including the sensitivity of the buoy 8, the response speed of the brake device 2, and the sealing effect of the closure device, must all guarantee high standards and high performance to ensure efficient and reliable operation.

[0044] It is worth noting that the quantitative acid extraction device disclosed in this embodiment can be used not only for lead-acid batteries of electric vehicles, but also for any occasions that require precise battery management. For example, in the uninterruptible power supply (UPS) system of the data center, solar energy storage system and other occasions, the consistency of the battery is also critical. Through this device, the management efficiency and service life of the battery can be greatly improved, the maintenance cost can be reduced, and the overall reliability and safety of the system can be improved.

[0045] Traditional battery maintenance methods often rely on manual inspection and adjustment. However, this solution uses an automated control system to not only improve accuracy and efficiency, but also solves problems that are difficult to overcome through manual operation through technical means.

[0046] Taking into account the continuous progress of battery technology and automatic control technology, the present invention can be further expanded, such as introducing intelligent algorithms to predict and optimize the acid extraction process, or remotely monitoring and controlling the acid extraction operation through wireless communication technology. These optimizations and expansions will further enhance the functions and application scope of the system, making it more in line with the needs of modern battery applications.
