Description

Technical Field

[0001] This application relates to the field of lead-acid batteries, and more particularly to a centralized negative pressure extraction device for lead-acid batteries. Background Technology

[0002] Lead-acid batteries are rechargeable DC power supplies that use lead and its oxides as electrodes and sulfuric acid solution as electrolyte. Due to their advantages of low cost, high safety, and strong starting performance, lead-acid batteries still hold an irreplaceable position in starting power supplies and low-to-mid-range energy storage. However, their disadvantages, such as low energy density, short cycle life, and heavy weight, are gradually squeezing them out of the high-end market, such as new energy vehicles and high-end energy storage, by lithium batteries. The future development direction of lead-acid batteries will focus on improving processes, such as lead-carbon batteries, to enhance cycle life and energy density, while simultaneously strengthening recycling technology to reduce lead pollution.

[0003] In actual production, batteries need to be filled with acid, but currently the batteries on the production line are on trays, which makes it impossible to perform negative pressure collection. This interferes with the normal operation of the production process and makes it difficult to meet the high requirements of continuous operation in the workshop. To address this issue, we propose a centralized negative pressure collection device for lead-acid batteries. Utility Model Content

[0005] This application provides a centralized negative pressure extraction device for lead-acid batteries, including a frame, a roller conveyor installed on the inner bottom wall of the frame, a set of trays above the roller conveyor, each tray containing a set of batteries, a sealing cover inside the frame, a first cylinder installed on the upper surface of the frame, a negative pressure pipe above the frame, a T-junction pipe connected to the top of the negative pressure pipe, a box connected to the bottom of the frame, a drive wheel inside the box, a motor inside the box, a second cylinder connected to the inner side wall of the box, and a plug plate connected to the top of the second cylinder.

[0006] Furthermore, the bottom end of the negative pressure tube is connected to the upper surface of the sealing cover.

[0007] Furthermore, the outer surface of the motor is connected to the inner wall of the housing, and the output end of the motor is connected to the back of the drive wheel.

[0008] Furthermore, the drive wheel is connected to the roller via a chain drive.

[0009] Furthermore, the bottom end of the first cylinder is connected to the upper surface of the sealing cover.

[0010] Furthermore, two sets of linear bearings are embedded in the upper surface of the frame, and a positioning rod is slidably connected to the inner wall of each linear bearing. The bottom end of each positioning rod is connected to the upper surface of the sealing cover.

[0011] Furthermore, an inspection panel is installed on the front of the enclosure.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The technical solution provided in this application has at least the following technical effects or advantages: By using a battery design with a tray on the production line, the negative pressure extraction process can be completed directly in the existing production process without the need to separately disassemble the tray. This avoids interference with the production process, meets the high requirements of continuous operation in the workshop, and improves overall production efficiency. Through efficient and stable centralized negative pressure extraction, the process effect after adding acid to the battery can be improved, which indirectly supports the improvement of lead-acid battery processes and is in line with the future development direction of lead-acid batteries. At the same time, it reduces potential problems in subsequent production links. Attached Figure Description

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example

[0016] Please see Figure 1-4In this utility model, a centralized negative pressure extraction device for lead-acid batteries includes a frame 11, a roller conveyor 2 installed on the inner bottom wall of the frame 11, a set of trays 3 above the roller conveyor 2, a set of batteries 12 inside each tray 3, a sealing cover 9 inside the frame 11, a first cylinder 6 installed on the upper surface of the frame 11, a negative pressure pipe 4 above the frame 11, a three-way pipe 5 connected to the top of the negative pressure pipe 4, a box 1 connected to the bottom surface of the frame 11, a drive wheel 15 inside the box 1, a motor 16 inside the box 1, a second cylinder 13 connected to the inner side wall of the box 1, and a plug plate 14 connected to the top of the second cylinder 13. Example

[0017] The bottom end of the negative pressure pipe 4 is connected to the upper surface of the sealing cover 9. The connection between the negative pressure pipe 4 and the sealing cover 9 facilitates the achievement of negative pressure inside the sealing cover 9. The outer surface of the motor 16 is connected to the inner wall of the housing 1, and the output end of the motor 16 is connected to the back of the drive wheel 15. The motor 16 facilitates the rotation of the drive wheel 15. The drive wheel 15 is connected to the roller conveyor 2 via a chain. The cooperation between the drive wheel 15 and the chain facilitates the movement of the roller conveyor 2.

[0018] The bottom end of the first cylinder 6 is connected to the upper surface of the sealing cover 9. The first cylinder 6 facilitates the movement of the sealing cover 9. Two sets of linear bearings 8 are embedded on the upper surface of the frame 11. Each linear bearing 8 has a positioning rod 7 slidably connected to its inner wall. The bottom end of each positioning rod 7 is connected to the upper surface of the sealing cover 9. Through the cooperation of the positioning rod 7 and the linear bearing 8, the sealing cover 9 is ensured to descend accurately and completely seal the tray 3, avoiding negative pressure leakage. A maintenance plate 10 is installed on the front of the box 1. Through the design of the maintenance plate 10, it can be quickly opened to inspect and maintain internal components such as the motor 16 and drive wheel 15, reducing equipment failure rate and maintenance costs.

[0019] The working principle of this application is: Start the motor 16 inside the box 1. The output of the motor 16 drives the drive wheel 15 to rotate. The drive wheel 15 drives the roller line 2 on the bottom wall of the frame 11 through chain transmission. The roller line 2 transports the tray 3 carrying the battery 12 to the bottom of the sealing cover 9. Then the second cylinder 13 on the inner side wall of the box 1 drives the insert plate 14 to rise and position the tray 3 to prevent the tray 3 from shifting in subsequent operations. Then, control the first cylinder 6 on the upper surface of the frame 11. The first cylinder 6 pushes the sealing cover 9 to move downward. During the movement of the sealing cover 9, the positioning rod 7 connected to it slides along the inner wall of the linear bearing 8 on the frame 11 to ensure that the sealing cover 9 descends vertically until the sealing cover 9 completely covers the tray 3 and the battery 12. An elastic sealing strip is installed in the annular groove on the frame 11. The frame 11 presses directly on the sealing strip to form a sealed space. The negative pressure is transmitted to the sealed space through the negative pressure pipe 4 above the frame 11. The three-way pipe 5 at the top of the negative pressure pipe 4 has two outlets. One outlet is connected to the negative pressure equipment and equipped with an electronic valve a. The other outlet is connected to an electronic valve b. After the negative pressure is drawn, valve a is closed and valve b is opened to quickly restore normal pressure. After the normal pressure is restored, the first cylinder 6 drives the sealing cover 9 to rise and reset, and the second cylinder 13 drives the insert plate 14 to fall and reset. The roller line 2 continues to run, transporting the processed tray 3 to the next process, while receiving new trays 3 to be processed, and entering the next work cycle.
