Technical Field

[0001] This utility model belongs to the field of storage battery production technology, and in particular relates to a protective agent application device for storage battery terminals. Background Technology

[0002] In the production of lead-acid batteries, sulfuric acid is encountered during the processes of adding acid, transferring batteries, placing them on shelves, and removing them from shelves. Furthermore, the batteries are exposed to acid mist for extended periods during charging, which can easily lead to corrosion of the battery terminals by sulfuric acid. Therefore, a protective agent must be applied to the battery terminals before adding acid to prevent corrosion.

[0003] In existing production operations, terminal protectant is usually applied manually. The protectant is applied to the battery terminals using an applicator. Since there are two battery terminals, each battery requires two applications to complete the application. This manual operation is not only labor-intensive but also has low overall application efficiency, which affects overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a protective agent application device for battery terminals. The upper end of the oil injection pipe is connected to the inside of the oil storage box. By pressing the pressing plate, the oil injection pipe is moved down, and the protective agent is applied to the battery terminals using a brush head. This solves the problem of low efficiency and impact on overall production efficiency caused by manual application.

[0028] Example 1

[0029] Please see Figure 1 and 2 As shown, this utility model is a protective agent application device for battery terminals, including a fixed bracket 1, which can be welded from plates and is fixed to the workbench by bolts.

[0030] The fixed bracket 1 is connected to a positioning plate 101, which has a U-shaped structure and is used to position the battery. The positioning plate 101 can be made of nylon. The fixed bracket 1 is fixedly connected to two guide sleeves 102. A connecting rod 103 that mates with the guide sleeves 102 is fixedly connected to the side wall of the positioning plate 101. The side wall of the guide sleeves 102 has threaded holes for screws to fix the connecting rod 103, which facilitates flexible disassembly and adjustment of the position of the positioning plate 101.

[0031] like Figure 3 and 4 As shown, the fixed bracket 1 is connected to the oil storage box 2 by screws. Two connecting pipes 201 are fixedly connected to the bottom wall of the oil storage box 2. The connecting pipes 201 communicate with the inside of the oil storage box 2, and the connecting pipes 201 are movably fitted with the oil injection pipe 3.

[0032] Specifically, the connecting pipe 201 is welded and fixed to the oil reservoir 2, or a threaded hole is opened on the bottom wall of the oil reservoir 2, and the connecting pipe 201 is connected by thread. A sealing ring is installed between the inner wall of the connecting pipe 201 and the oil injection pipe 3 to prevent the protective agent from leaking.

[0033] Connecting ears 202 are welded to both sides of the oil storage box 2. The connecting ears 202 are located on opposite sides of the oil storage box 2, and guide rods 401 are movably inserted through both connecting ears 202. A pressing plate 4 is fixedly connected to the upper end of the two guide rods 401. A spring 402 is sleeved on the guide rod 401, and the spring 402 is located between the connecting ears 202 and the pressing plate 4. When the pressing plate 4 is pressed, the spring 402 is compressed. After the pressing plate 4 is released, it moves upward and resets under the action of the spring 402.

[0034] The upper end of the oil injection pipe 3 is connected to the inside of the oil reservoir 2, allowing the protective agent inside the oil reservoir 2 to flow into the oil injection pipe 3. The lower end of the oil injection pipe 3 is connected to a brush head 301. The brush head 301 can be made of materials in the existing technology, or sponge, etc. The lower surface of the brush head 301 can be provided with countersunk holes that are compatible with the terminals, so that the coating on the terminal surface can be more thorough.

[0035] like Figures 5-8 As shown, two oil injection pipes 3 are fixedly connected to a connecting plate 302, and the connecting plate 302 is connected to the guide rod 401. The battery 5 is inserted into the positioning plate 101. After being positioned by the positioning plate 101, pressing the pressing plate 4 removes the constraint of the guide rod 401 from the connecting plate 302, causing the connecting plate 302 and the oil injection pipes 3 to move downwards. This allows the brush head 301 to apply protective agent to the battery terminals. The installation positions of the two oil injection pipes 3 are set according to the spacing of the battery terminals, so that pressing the pressing plate 4 once can complete the application of protective agent to both terminals on one battery, thus effectively improving the application efficiency.

[0036] Example 2

[0037] like Figure 4 , 7 As shown in Figure 8, based on Embodiment 1, the pressing plate 4 is fixedly connected to a piston rod 403 that cooperates with the oil injection pipe 3. The guide rod 401 is movably inserted between the guide rod 401 and the connecting plate 302, and the guide rod 401 is fixedly connected to a limiting block 404 located below the connecting plate 302. The limiting block 404 can be a fixing ring, so that when the pressing plate 4 moves upward, it can drive the connecting plate 302 through the limiting block 404, thereby driving the two oil injection pipes 3 to move upward and reset.

[0038] Meanwhile, an oil inlet 303 is provided on the side wall at the upper end of the oil injection pipe 3, and when the oil injection pipe 3 is at its highest point, the lower side of the oil inlet 303 is not higher than the inner bottom wall of the oil storage box 2, so that the protective agent in the oil storage box 2 can always be automatically filled into the oil injection pipe 3.

[0039] After the battery 5 is positioned, pressing the pressing plate 4 causes the guide rod 401 to move downwards, and the connecting plate 302 loses the support of the limiting block 404, causing the two oil injection pipes 3 to move downwards. When the brush head 301 comes into contact with the battery terminal, the oil injection pipe 3 can no longer move downwards. At this time, the pressing plate 4 continues to move downwards, and the piston column 403 moves downwards and inserts into the oil injection pipe 3, thereby squeezing the protective agent in the oil injection pipe 3 out of the brush head 301, ensuring that there is sufficient protective agent on the brush head 301, improving the reliability of the coating, and making the coating of the protective agent on the terminal surface more thorough.

[0040] Preferably, the lower end of the guide rod 401 has a stepped shaft structure, with the smaller diameter section interlocking with the connecting plate 302. When the pressing plate 4 is pressed, the stepped surface of the guide rod 401 presses down on the connecting plate 302, thereby providing a certain downward pulling force to the oil injection pipe 3, which in turn improves the contact effect between the brush head 301 and the battery terminal, further ensuring that the coating on the terminal surface is more thorough and reliable.
