Tank formation manufacturing technology for storage batteries

Abstract

The invention discloses a tank formation manufacturing technology for storage batteries,relates to the field of lead-acid storage battery production and solves the problem of the poor welding quality between bus-bars and electrode tabs. The manufacturing technology comprises the technological processes of feeding of plate packs in an assembly box, electrode tab arrangement, cutting and brushing of electrode tabs, dipping of flux, cast-welding, inspection and discharging after qualification. The cast-welding process is performed through a cast-welding machine and comprises the following steps: 1) heating of a lead pan; 2) preheating of a lower die; 3) scrapping of molten lead; 4) electrode tab cast-welding; 5) water cooling; 6) water vapor mixing cooling; 7) gas cooling; 8) secondary preheating of the lower die; and 9) feeding of the electrode tabs in battery containers. The manufacturing technology is used for cast-welding of lead-acid storage battery grids.

Description

technical field [0001] The invention relates to the field of lead-acid storage batteries, in particular to an externalized storage battery manufacturing process. Background technique [0002] 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 plate, and put the welded electrode group into the battery slot. The welding quality is greatly affected by the experience and skills of the personnel, and it is easy to cause the separator to be burned, the surface of the bus bar to be uneven, with lead slag and burrs; the thickness of the lug welding, false welding, and tab welding is difficult to reach the thickness of the bus bar .

AI Technical Summary

Problems solved by technology

This semi-automatic casting and welding method is labor-intensive, the time and temperature of casting and welding are not easy to control, and quality problems such as false welding of tabs are prone to occur.

In recent years, casting and welding machines have also been used for automatic casting and welding, but there are often quality problems such as low casting and welding pass rate, uneven busbars or even holes, and false welding of tabs.
