Embodiment Construction

[0012] Follow the steps below:

[0013] 1. First, according to the structure and size of the battery bus bar, make a toothed bus bar fixture with the inner cavity consistent with the bus bar, and one side with a tooth groove; the fixture is equipped with an electric heating device around it;

[0014] 2. Put the battery plate perpendicular to the ground according to the width direction, and put the tabs on the same side into the tooth grooves of the bus bar fixture in turn;

[0015] 3. Use the quantitative lead supply pump to inject the molten lead in the lead melting pot into the bus bar fixture, immerse the tabs in the lead liquid, and keep the fixture at 360-380 0 C, to maintain the fluidity of molten lead;

[0016] 4. Hold a 1000W heating rod and insert it into the lead liquid, and perform fusion welding on each tab in turn;

[0017] 5. After the jig is cooled and removed, the bus bar is cast and welded with the pole plate, and then the same jig is used for the next set o...

Abstract

The invention disclose a casting and welding method of a lead-acid storage battery busbar, which comprises the steps of: sequentially placing a battery pole plate and pole lugs on the same side in tooth sockets of a busbar clamp according to a width direction vertical to the ground; injecting molten lead in a lead melting pot into the busbar clamp, and insulating; and sequentially melting and welding the pole lugs by using a heating rod. According to the invention, when the busbar is welded, the welding and melting depth and the bonding area can be ensured, pseudo welding and over welding are not caused, and the short circuiting of the molten lead can be avoided, therefore, the welding quality of the lead-acid storage battery is ensured, the electric property of the battery is improved, and the service life of the lead-acid storage battery is prolonged.

Description

technical field [0001] The invention relates to a method for manufacturing a lead-acid storage battery, in particular to a method for casting and welding busbars of a lead-acid storage battery. Background technique [0002] The lead-acid battery bus bar connects the tabs on the battery plate to conduct electricity. There are generally two ways to weld the existing collector. One is that the height direction of the plate is perpendicular to the ground, and the upper part of the plate lug is manually welded with combustible gas. The other is that the height direction of the plate is perpendicular to the ground. The tabs are cast-welded with equipment at the bottom. The existing manual welding is limited by the level of operators and gas pressure. During the welding process, it is inevitable that some internal short-circuits, or even virtual welding and over-welding will be caused by insufficient melting depth or welding lead, which will seriously reduce the electrical perform...
