A manufacturing process of internalized storage battery

Abstract

The invention discloses a production process of an inner formation storage battery, and belongs to the field of a lead-acid storage battery, and solves the easily occurring welding quality problem of a bus-bar and a lug. The process comprises the following steps of loading a plate group into an assembling box, arranging a lug, cutting and brushing the lug, dipping soldering flux, cast welding, inspecting and qualification and down-conversion, wherein the cast welding flow is carried out by adopting a cast welding machine. The cast welding flow comprises the following steps of (1) heating a lead pot; (2) loading a mold and preheating the mold; (3) scraping the lead liquid; (4) cast welding the plate group; (5) cooling the plate group through water; (6) cooling the plate group collectively through water and air; (7) cooling the plate group through the air; (8) loading the mold and preheating the mold again; and (9) loading the plate group into a tank. The production process is suitable for the cast welding of the inner formation storage battery with positive grid alloy being lead calcium tin aluminum or lead calcium alloy series grid.

Description

technical field

[0001] The invention relates to the field of lead-acid storage batteries, in particular to a manufacturing process for internalized storage batteries. Background technique

[0002] In the lead-acid battery industry, the national policy encourages the adoption of advanced internal synthesis technology and gradually restricts the production mode of external synthesis. In China, internal synthesis production technology has been paid more and more attention, and has attracted more and more attention from people. Internalization into welding is a very critical process. The traditional lead-acid battery welding process is manual welding with oxyacetylene. The traditional manual welding is usually to put the packaged pole group into the pole group box first, then snap the tabs into the comb board, and then shape and press them with clip strips. , and then place the cast parts at the position of the busbar parts, weld them with an oxyacetylene torch, remove the comb...
