Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and particularly relates to a lead-acid battery charging and forming negative pressure pumping device. Background Technique

[0002] After the power lead-acid battery is assembled, the battery is internally formed through repeated charging and discharging to transform the internal plate composition so as to meet the user's usage requirements. Currently, the atmospheric pressure forming mode is adopted, and the forming efficiency is low. The forming time is 54 - 72 hours, seriously affecting the production efficiency.

[0003] The negative pressure charging and forming process can improve the forming efficiency to a certain extent. For example, Chinese Utility Model CN216213980U discloses an acid adding pot structure for a storage battery. By opening a through port at the upper end of the partition plate, each single cell cavity is made to communicate, so that the pressure in each single cell cavity in the acid adding pot is balanced during vacuum pumping, which is beneficial to improving the overall acid adding efficiency. By setting the acid filling port on the pot cover as an ellipse, the positioning convenience between the acid filling machine and the pot cover is improved, which is beneficial to improving the acid filling efficiency and thus improving the overall production efficiency.

[0004] However, in the above-mentioned prior art, it is not convenient to accurately pump negative pressure for a single acid adding pot, resulting in poor flexibility and adaptability in production use. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a lead-acid battery charging and forming negative pressure pumping device. By covering the acid adding pot cover with a cover plate tooling and connecting it to the negative pressure pumping device through a tubular interface, negative pressure is pumped for the acid adding pot, solving the problems of inconvenient accurate negative pressure pumping for a single acid adding pot and poor flexibility and adaptability in use in the prior art.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a lead-acid battery charging and forming negative pressure pumping device, including a cover plate tooling that cooperates with the acid adding pot cover. The cover plate tooling has a surrounding edge that encloses the outside of the acid adding pot cover. A sunken groove is provided on the lower surface of the cover plate tooling, and a sealing ring is connected and arranged around the sunken groove. A tubular interface is provided on the upper surface of the cover plate tooling, and the tubular interface is communicated with the sunken groove for connecting the acid filling ports of the acid adding pot cover through the sunken groove to realize simultaneous negative pressure pumping for each single cell cavity of the acid adding pot.

[0008] As a preferred technical solution of the utility model, a plurality of baffles are arranged on the inner wall of the tubular interface to block the electrolyte carried out during negative pressure pumping.

[0009] As a preferred technical solution of the utility model, the baffles are arranged up and down and staggered with each other.

[0010] As a preferred technical solution of the utility model, a sealing strip is installed on the inner wall of the surrounding edge to achieve sealing between the surrounding edge and the acid adding pot cover.

[0011] As a preferred technical solution of the utility model, the top wall of the sink is provided with reinforcing ribs.

[0012] As a preferred technical solution of the utility model, the reinforcing ribs are arranged in a criss-cross pattern.

[0013] The utility model has the following beneficial effects:

[0026] Embodiment 1

[0027] Please refer to Figure 1 and 2 As shown, the present invention is a lead-acid battery charging and forming negative pressure pumping device, including a cover plate tooling 1 that cooperates with the acid adding pot cover body 5, that is, the cover plate tooling 1 covers the acid adding pot cover body 5.

[0028] Specifically, as Figures 3 to 5 shown, the cover plate tooling 1 has a perimeter edge 101 surrounding the outside of the acid adding pot cover body 5. The lower surface of the cover plate tooling 1 is provided with a sunk groove 102 and is connected with a sealing ring 2 arranged around the sunk groove 102. Among them, the top wall of the sunk groove 102 is provided with reinforcing ribs 105, and the reinforcing ribs 105 are arranged in a crisscross pattern, so that the structural strength of the cover plate tooling 1 is improved, and the situation that the cover plate tooling 1 deforms during negative pressure pumping is avoided.

[0029] The upper surface of the cover plate tooling 1 is provided with a tubular interface 103, and the tubular interface 103 is communicated with the sunk groove 102. The tubular interface 103 is connected to the negative pressure pumping device through a pipeline, and is used to make the respective acid filling ports of the acid adding pot cover body 5 communicate through the sunk groove 102, so as to synchronously pump negative pressure on the respective single-cell cavities of the acid adding pot 4, thereby realizing accurate negative pressure pumping on the acid adding pot 4.

[0030] In addition, multiple cover plate toolings 1 are connected to a main pipeline through pipelines to synchronously pump negative pressure on multiple acid adding pots 4, improving the overall negative pressure pumping efficiency.

Specifically, taking two of the two baffles 104 as an example, the two baffles 104 are arranged up and down and staggered with each other, so that when the negative pressure is drawn, the electrolyte is prevented from being brought out directly.

[0033] At the same time, a sealing strip 3 is installed on the inner wall of the surrounding edge 101 to achieve sealing between the surrounding edge 101 and the acid adding pot cover 5, thereby further improving the overall sealing between the cover plate tooling 1 and the acid adding pot cover 5 and ensuring reliability when pumping negative pressure.
