Problems solved by technology

The manufacturing method of power lead-acid battery pole group is mainly manual welding, which has a low degree of automation. Due to manual operation, the welding quality of the pole group is poor, and the welding process is easy to produce lead beans. These manual welding The disadvantages have seriously affected the quality of lead-acid batteries. At the same time, as the national environmental protection requirements continue to increase, traditional manual welding can no longer meet environmental protection requirements. In order to adapt to national policies and improve the welding quality of lead-acid batteries, automatic casting welding is used. The method of line production of lead-acid batteries for traction has become the best choice
[0003] Since domestic automatic casting and welding wires are mainly used for the production of small electrode groups of plate-type lead-acid batteries, the thickness of the positive plate and the negative plate lug is the same, while the thickness of the positive plate and negative plate lug of the tubular power lead-acid battery is different, and the existing There are separators enclosing the tubular positive plate, and the size of the pole group is relatively large. It is still blank to use cast welding wires for the production of large power lead-acid battery pole groups.

Abstract

The invention relates to a large power lead-acid storage battery plate group manufacturing method and a lead-acid storage battery plate group, and belongs to the technical field of storage batteries. The method comprises polar plate treatment, positive plate encapsulation, polar plate matching and cast welding, and specifically comprises the following steps: cutting and polishing plate lugs of a positive plate, a negative plate and a side plate, and cleaning frames of the side plate and the negative plate; the front plate is fed into the partition plate sleeve, and the bottom of the partition plate sleeve and the front plate plastic sealing bottom are sealed after packaging is completed; stacking is carried out after the plates are stacked and assembled into plate groups, the plate groups are conveyed to a cast-weld clamp to be clamped, and the plate groups and the tabs are arranged; after the copper core is preheated, the copper core is loaded into a cast-weld mold, lead alloy liquid is injected into the cast-weld mold, the mold is opened after the cast-weld mold is automatically cooled, and cast-weld of the plate group is completed; the lead-acid storage battery plate group is manufactured by the manufacturing method of the large power lead-acid storage battery plate group; automatic production of large power lead-acid storage battery pole groups can be achieved, the production efficiency is improved, the battery quality is improved, and the environment-friendly requirement is met.

Description

technical field [0001] The invention relates to a method for manufacturing a large power lead-acid battery pole group and the lead-acid battery pole group, belonging to the technical field of storage batteries. Background technique [0002] At present, lead-acid batteries for traction as DC power supplies are mainly used in forklifts, trucks, underground mining locomotives and other equipment, and are widely used in airports, stations, ports, docks, industrial and mining enterprises and other fields. The manufacturing method of power lead-acid battery pole group is mainly manual welding, which has a low degree of automation. Due to manual operation, the welding quality of the pole group is poor, and lead beans are easy to be produced during the welding process.
