High-precision lead-acid battery acid and liquid supplementing device

Abstract

The invention discloses a high-precision lead-acid battery acid and liquid supplementing device. The high-precision lead-acid battery acid and liquid supplementing device comprises a vacuumizing device and a plurality of liquid supplementing units, wherein the plurality of liquid supplementing units are sequentially connected through a positioning plate; every liquid supplementing unit is composed of a housing and a quantitative pumping and filling injector fixed inside the housing through a positioning structure, the housing is open at the lower end and closed at the upper end, a liquid storage chamber is formed between the positioning structure and the closed end of the housing, both ends of the quantitative pumping and filling injector are open at both ends, and the upper end of the quantitative pumping and filling injector extends into the liquid storage chamber; the vacuumizing device is communicated with the liquid storage chamber of every supplementing unit through a pipeline module. The high-precision lead-acid battery acid and liquid supplementing device pumps sulfuric acid electrolyte into the quantitative pumping and filling injector of every liquid supplementing unit through atmospheric pressure, and the overflow part of the sulfuric acid electrolyte can flow into the liquid storage chambers; due to the facts that the quantitative pumping and filling injectors are basically the same in volume and small in diameter, during a liquid supplementing process, acid liquid can completely and rapidly flow out and avoid hanging. Therefore, the high-precision lead-acid battery acid and liquid supplementing device can improve the production efficiency of storage batteries and is applicable to high-precision acid and liquid supplementation.

Description

technical field [0001] The invention relates to a device for quantitatively adding sulfuric acid electrolyte in the manufacturing process of lead-acid batteries. Background technique [0002] Lead-acid batteries are the most commonly used secondary chemical power sources. They are widely used in industrial production and people's daily life, and play an important role in many fields such as automobile starting, power batteries, communication base stations, and photovoltaic systems. [0003] In the production process of lead-acid batteries, acid is added after the battery plates are assembled into the primary battery. Adding acid is an important production process and process link. The amount of sulfuric acid electrolyte added to each battery cell will directly affect the performance of the entire battery. The uniformity between the cells of the battery is very important. The traditional sulfuric acid electrolyte addition process generally adopts a "measuring cup" quantitati...

AI Technical Summary

Problems solved by technology

The traditional sulfuric acid electrolyte addition process generally adopts a "measuring cup" quantitative liquid addition device, the diameter of the measuring cup is large, and the accuracy of liquid addition is relatively low, thereby reducing the accuracy of the total acid content of the sulfuric acid electrolyte in each cell in the battery; In the production process of chemical formation, especially internal chemical formation, it is necessary to use the process of supplementing acid to make the total amount of sulfuric acid meet the requirements for the use of lead-acid batteries. However, the existing process of supplementing acid is basically manual operation, and the workload is heavy.
