Description

Technical Field

[0001] This utility model relates to the technical field of lead-acid battery processing, and in particular to a vacuum pumping component for adding acid to lead-acid batteries. Background Technology

[0002] Lead-acid batteries are devices that directly convert chemical energy into electrical energy. They are designed for rechargeability, achieving recharging through a reversible chemical reaction. They are a type of battery, belonging to the category of secondary batteries. Their working principle is as follows: during charging, external electrical energy regenerates the internal active materials, storing electrical energy as chemical energy. When discharging is needed, the chemical energy is converted back into electrical energy for output. After the power source is removed, it returns to its pre-discharge state, forming a chemical battery. Rechargeable batteries can be repeatedly charged and discharged; a battery is a battery pack composed of one or more individual cells.

[0003] In the manufacturing process of lead-acid batteries, the acid-adding operation is a crucial step in ensuring battery quality. Acid-adding machines are commonly used for this process. These machines are employed to inject electrolyte into the batteries and are a key component of battery manufacturing.

[0004] In order to ensure good acid addition effect, existing acid adding machines require vacuuming of the battery to be added. However, the vacuuming effect of existing acid adding machines is poor and the functional integration is low, which leads to low production efficiency and poor production effect. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of poor vacuuming effect in the existing technology during acid addition process, and provides a vacuuming component for adding acid to lead-acid batteries with good vacuuming effect.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a vacuum assembly for adding acid to a lead-acid battery, comprising a frame, wherein the frame is equipped with:

[0007] An acid-adding assembly is provided with a plurality of acid-adding cups. The upper end of each acid-adding cup is connected to an acid quantity control assembly, and the lower end of each acid-adding cup is connected to an acid-adding hose. The lower end of the acid-adding assembly is provided with a longitudinally movable acid-adding nozzle assembly, which is connected to the acid-adding hose. The acid-adding assembly is provided with an acid discharge opening and closing mechanism that can open and close the acid-adding hose.

[0008] The vacuum pipeline is connected to an external vacuum pump and a vacuum hose. The vacuum hose is connected to the upper end of the acid addition cup. The vacuum assembly is equipped with a vacuum opening and closing mechanism that allows the vacuum hose to be opened and closed.

[0009] This vacuuming assembly includes an acid-adding component located below the acid quantity control component. The acid quantity control component regulates the amount of acid added each time. An acid-adding cup is installed within the acid-adding component. The upper end of the acid-adding cup is connected to the acid quantity control component via a connecting hose, and the lower end of the acid-adding cup is connected to an acid-adding nozzle assembly via another connecting hose. The acid-adding assembly includes an acid-discharge opening and closing mechanism that controls the opening and closing of the acid-adding hose, thereby controlling the addition of acid from the acid-adding cup to the battery through the acid-adding nozzle assembly. During vacuuming operations, the acid-adding hose is closed. This vacuuming assembly also includes a vacuum line connected to a vacuum pump. A vacuum hose is connected to the middle of the vacuum line and is connected to the upper end of the acid-adding cup. This vacuuming assembly also includes a vacuum opening and closing mechanism for the vacuum hose. During the acid-adding operation, the battery is first transported to the acid-adding point via a conveyor line. The acid-adding nozzle assembly can move longitudinally, and its downward movement connects the acid-adding nozzle assembly to the battery. Then, acid is added quantitatively into the acid quantity control assembly. After the acid-adding is completed, the vacuum assembly evacuates the internal acid storage chamber of the battery to ensure that the acid is quantitatively added during the acid-adding process, and that the acid is evenly distributed after entering the battery, thus achieving precise addition and improving the acid-adding efficiency and effect.

[0010] Preferably, the acid release opening and closing mechanism includes a fixed plate mounted on a frame, an acid release pressure plate mounted on the outer side of the fixed plate, an acid release cylinder connected to the fixed plate, and an acid release rod connected to the telescopic end of the acid release cylinder passing through the fixed plate and the acid release pressure plate. The acid addition hose is placed between the acid release pressure plate and the acid release rod. Specifically, the fixed plate in the acid release opening and closing mechanism, the acid release pressure plate on the outer side of the fixed plate, the acid release cylinder on the fixed plate, and the acid release rod connected to the telescopic end of the acid release cylinder, allow the acid release cylinder to move the acid release rod towards the acid release pressure plate. Simultaneously, the acid addition hose is inserted between the corresponding acid release pressure plate and the acid release rod. The movement of the acid release rod controls the opening and closing of the acid addition hose. This structural design enables automated control of acid addition, improves the efficiency of acid addition operations, and can be used in conjunction with vacuum pipelines and vacuum hoses to complete vacuuming operations, ensuring good vacuuming results.

[0011] Preferably, the acid filling nozzle assembly includes a support plate mounted on the frame, a drive nut connected to the support plate, an mounting plate at the lower end of the support plate, a drive motor connected to the mounting plate, a drive screw connected to the rotating end of the drive motor, the drive screw being connected to the drive nut, and a plurality of filling nozzles connected to the lower end of the mounting plate, the filling nozzles being connected to the acid filling hose. The acid filling nozzle assembly includes a support plate mounted on a frame. A drive nut is installed on the support plate, and a mounting plate is located at its lower end. The mounting plate is connected to a drive motor, the rotating end of which is connected to a drive screw. The drive screw is connected to the drive nut. Rotation of the drive motor causes the drive screw to rotate, resulting in relative movement between the drive screw and the drive nut. This, in turn, causes the mounting plate to move vertically. Several filling nozzles are located at the lower end of the mounting plate, their arrangement corresponding to the battery's acid filling port. These nozzles are connected to acid filling hoses. This structure enables vertical movement of the acid filling nozzle assembly, automating the acid filling operation and improving efficiency. The nozzles are tightly connected to the battery's acid filling port, preventing leakage during vacuuming and improving the vacuuming effect. The shared path for acid filling and vacuuming simplifies the structure and makes operation convenient.

[0012] Preferably, the support plate is connected to a guide seat, and the mounting plate is connected to a guide rod, with the guide rod sleeved on top of the guide seat. Specifically, two guide seats are installed on the support plate, positioned on either side of the drive nut. Simultaneously, the mounting plate is connected to a guide rod, which sleeves on the guide seat. The guide rod and guide seat provide guidance, ensuring stable vertical movement of the mounting plate.

[0013] Preferably, a positioning block is connected to the bottom surface of the mounting plate. The bottom of the positioning block has a U-shaped groove, and the inner wall of the groove has a guide slope. Specifically, the positioning block, with its U-shaped groove, is mounted on the bottom surface of the mounting plate. This groove allows the acid-adding nozzle assembly to engage with the battery as it moves downwards, ensuring battery stability during acid addition and preventing tipping. This guarantees acid addition stability, thus ensuring the effectiveness and efficiency of acid addition. Simultaneously, the guide slope on the inner wall of the groove facilitates the insertion of the battery into the groove, improving the connection between the acid-adding nozzle assembly and the battery, facilitating subsequent acid addition operations, and increasing the efficiency of the acid addition process.

[0014] Preferably, the vacuum hose is connected to a vacuum manifold at its end, and the vacuum manifold is equipped with several vacuum nozzles. These vacuum nozzles communicate with the top of the acid-adding cup, and the lower end of the vacuum manifold is connected to an air inlet hose. The vacuum manifold, with its several vacuum nozzles communicating with the top of the acid-adding cup, and the air inlet hose at its lower end, ensures pressure balance in the acid-adding cup. This allows for the addition of acid from the cup to the battery after vacuuming, ensuring all acid is added and guaranteeing the effective acid-adding process.

[0015] Preferably, the vacuum opening and closing mechanism includes several sets of connecting plates mounted on the frame. Each connecting plate is connected to a mounting column, and each mounting column is connected to a telescopic cylinder. The telescopic end of each telescopic cylinder is connected to a vacuum rod. The vacuum hose and the air inlet hose are respectively positioned between the corresponding vacuum rod and the connecting plate. The connecting plates are mounted on the frame and have mounting columns for mounting the telescopic cylinders. Each telescopic cylinder has a corresponding vacuum pipe. The vacuum hose passes between one set of vacuum rods and the connecting plate, and the air inlet hose passes between the other set of vacuum rods and the connecting plate. The telescopic movement of the cylinders moves the vacuum rods, thus controlling the opening and closing of the vacuum hose and the air inlet hose. This allows for control of the vacuuming and acid-adding operations, ensuring that the acid is evenly distributed in the battery during acid addition, guaranteeing the acid-adding effect and improving efficiency.

[0016] The beneficial effects of this utility model are: the vacuuming assembly integrates an acid-adding assembly, which allows for vacuuming before acid addition, and enables vacuuming and acid addition to share the same pipeline, facilitating pipeline layout. At the same time, it can ensure the effectiveness of vacuuming and acid addition, and improve production and processing efficiency and results. Attached Figure Description

The mounting columns 58 are connected to telescopic cylinders 59. The telescopic end of the telescopic cylinders 59 is connected to a vacuum pressure rod 60. The vacuum hose 51 and the air inlet hose 56 are respectively placed between the corresponding vacuum pressure rod 60 and the connecting plate 57.

[0034] The working principle of this utility model is as follows: Figure 1-6 As shown, this vacuuming assembly includes an acid-adding component located below the acid quantity control component. The acid quantity control component controls the amount of acid added each time. An acid-adding cup is installed within the acid-adding component. The upper end of the acid-adding cup is connected to the acid quantity control component via a connecting hose, and the lower end of the acid-adding cup is connected to an acid-adding nozzle assembly via an acid-adding hose. The acid-adding component includes an acid-discharging opening and closing mechanism that controls the opening and closing of the acid-adding hose, thereby controlling the addition of acid from the acid-adding cup to the battery through the acid-adding nozzle assembly. During vacuuming operations, the acid-adding hose is in a closed state. This vacuuming assembly also includes a vacuum pipeline connected to a vacuum pump. A vacuum hose is connected to the middle of the vacuum pipeline and is connected to the upper end of the acid-adding cup. This vacuuming assembly also includes a vacuum opening and closing mechanism for the vacuum hose. During the acid-adding operation, the battery is first transported to the acid-adding point via a conveyor line. The acid-adding nozzle assembly can move longitudinally, and its downward movement connects the acid-adding nozzle assembly to the battery. Then, acid is added quantitatively into the acid quantity control assembly. After the acid-adding is completed, the vacuum assembly evacuates the internal acid storage chamber of the battery to ensure that the acid is quantitatively added during the acid-adding process, and that the acid is evenly distributed after entering the battery, thus achieving precise addition and improving the acid-adding efficiency and effect.

[0035] The acid discharging opening and closing mechanism includes a fixed plate with an acid discharging pressure plate on its outer side. An acid discharging cylinder is mounted on the fixed plate, and an acid discharging rod is connected to the telescopic end of the cylinder. The cylinder can move the rod towards the pressure plate. Simultaneously, an acid-adding hose is inserted between the pressure plate and the rod. The movement of the rod controls the opening and closing of the hose. This design enables automated control of acid discharging, improving operational efficiency. It can also be used with vacuum lines and hoses to perform vacuuming operations, ensuring a good vacuuming effect.

[0036] The acid filling nozzle assembly includes a support plate mounted on a frame. A drive nut is installed on the support plate, and a mounting plate is located at its lower end. The mounting plate is connected to a drive motor, the rotating end of which is connected to a drive screw. The drive screw is connected to the drive nut. Rotation of the drive motor causes the drive screw to rotate, resulting in relative movement between the drive screw and the drive nut. This, in turn, causes the mounting plate to move vertically. Several filling nozzles are located at the lower end of the mounting plate, their arrangement corresponding to the battery's acid filling port. These nozzles are connected to acid filling hoses. This structure enables vertical movement of the acid filling nozzle assembly, automating the acid filling operation and improving efficiency. The nozzles are tightly connected to the battery's acid filling port, preventing leakage during vacuuming and improving the vacuuming effect. The shared path for acid filling and vacuuming simplifies the structure and makes operation convenient.

[0037] Two guide seats are installed on the support plate and arranged on both sides of the drive nut. At the same time, the mounting plate is connected to a guide rod, which is sleeved with the guide seat. The guide rod and the guide seat can play a guiding role to ensure the vertical movement of the mounting plate is stable.

[0038] The mounting plate includes a connecting positioning block with a U-shaped slot on its bottom surface. This slot engages with the battery when the acid filling nozzle assembly moves downwards, ensuring battery stability during acid filling and preventing tipping. This stability guarantees the effectiveness and efficiency of acid filling. Furthermore, the guide slope on the inner wall of the slot facilitates battery insertion, improving the connection between the acid filling nozzle assembly and the battery, thus simplifying subsequent acid filling operations and increasing efficiency.

[0039] The vacuum hose is connected to a vacuum tube at one end, which has several vacuum nozzles connected to the top of the acid filling cup. At the same time, an air inlet hose is connected to the lower end of the vacuum tube. The air inlet hose ensures the air pressure balance in the acid filling cup and is used to add the acid in the acid filling cup into the battery after vacuuming, ensuring that all the acid in the acid filling cup is added to the battery and ensuring the acid adding effect.

[0040] The vacuum opening and closing mechanism includes several sets of connecting plates mounted on the frame. Each connecting plate is connected to several mounting columns for mounting telescopic cylinders. The telescopic ends of these cylinders are connected to vacuum rods. Each pair of telescopic cylinders corresponds to one vacuum hose. A vacuum hose passes between one set of vacuum rods and the connecting plates, while an air inlet hose passes between the other set of vacuum rods and the connecting plates. The telescopic movement of the cylinders moves the vacuum rods, thus controlling the opening and closing of the vacuum hoses and air inlet hoses. This controls the vacuuming and acid-adding operations, ensuring that the acid is evenly distributed throughout the battery during acid addition, guaranteeing the acid-adding effect and improving efficiency.

[0041] The working steps of this component are as follows: The drive motor 434 in the acid filling nozzle assembly 43 drives the drive screw 436 to rotate. After engaging with the drive nut 432, the mounting plate moves downward. The slot 439 at the bottom of the positioning block 438 on the mounting plate locks the battery, allowing the filling nozzle 437 to be inserted into the battery, completing the matching installation of the acid filling nozzle assembly 43. Simultaneously, the connecting hose between the acid level control component and the acid filling cup is closed, the vacuum pump starts, the air inlet hose 56 is closed by the vacuum opening and closing mechanism 53, and the vacuum hose 51 is open. At the same time, the acid filling hose 41 is closed by the acid discharging opening and closing mechanism 42. In this state, the vacuuming assembly 5 can create a vacuum inside the battery. This structure ensures good vacuuming effect and is simple and convenient to operate.
