Encapsulation method of improved lead-acid storage battery upper cover

Abstract

The invention discloses an encapsulation method of an improved lead-acid storage battery upper cover. The encapsulation method comprises following steps: step a, the improved lead-acid storage battery upper cover is prepared, wherein the inside of a lead-acid storage battery is provided with cells; the cells are provided with bridging lead columns (3), and probe holes (1) are arranged at positions on the improved lead-acid storage battery upper cover, which are corresponding to the bridging lead columns (3); step b, probes (2) are prepared; step c, a front cover plate of the improved lead-acid storage battery upper cover is provided with an insulating block; step d, glue pouring is performed; and step e, the probes (2) are inserted into the probe holes, and glue encapsulating is performed. The encapsulation method is capable of realizing detection on voltage or internal resistance of the cells inside; the probes with a small diameter are used as measuring carrier of cell voltage; improvement on the bridging lead columns is not necessary; improvement on traditional upper covers is less; normal glue encapsulating operation is capable of realizing sealing of the probe holes; technological operation is simplified; occurrence rate of acid leakage of a leading-out terminal is reduced; and battery reliability is increased.

Description

Technical field [0001] The invention relates to a battery production technology, in particular to a method for packaging the upper cover of a lead-acid battery. Background technique [0002] Lead-acid batteries with a capacity that is not particularly large (capacity less than 200Ah) generally consist of 3 cells, 4 cells, and 6 cells in series to form a battery combination with a nominal voltage of 6V, 8V, and 12V. Because this kind of battery pack only has positive and negative lead-out methods at both ends, and all the monomers in the middle do not have any lead-out carriers inside the battery, it can only measure the voltage or internal resistance of the entire battery pack, but cannot The monomer is measured. Therefore, the disadvantage is that the internal monomers cannot be measured and the performance of the individual monomers in the entire battery cannot be reflected very effectively. [0003] In view of the above-mentioned shortcomings in the traditional design methods ...

AI Technical Summary

Problems solved by technology

Its advantage is that no new parts are introduced, and the lead-out poles are thicker, which can withstand a larger equalization current; but at the same time, the problem it brings is that the number of seals in the process increases. Taking 12V batteries as an example, traditional batteries Only the positive and negative terminals need to be sealed, and the number of seals is 2. In addition to the positive and negative terminals of the battery made in this way, the other 5 bridging terminals still need to be sealed, and the number of seals reaches 7, which greatly increases The workload and glue consumption are reduced, and the more seals are used at the same time, the greater the risk of battery acid leakage, which will have an adverse effect on the reliability of the battery.
