Welding device and welding method for bus-bar of lead-acid storage battery

Abstract

The invention discloses a welding device and a welding method for a bus-bar of a lead-acid storage battery. The characteristic that fusion welding through flame heating is full and thorough, so that inevitable quality problems of a cast-welding mode of fault welding, false welding, skip welding and the like are avoided, and the welding method and the welding device have the advantages of low production cost, simple operation, convenient maintenance, reliable welding quality and the like. On the basis, by adopting the welding device, automatic operation can be realized; the production efficiency is 10 times higher than that of manual welding operation; and welding quality and reliability are further improved.

Description

technical field [0001] The invention relates to the technical field of lead-acid battery busbar welding, in particular to a lead-acid battery busbar welding device and method. Background technique [0002] Lead-acid batteries have played an indispensable and important role in various economic fields such as transportation, communication, electric power, military affairs, navigation and aviation. Lead-acid batteries have developed into the battery products with the largest output in the world, accounting for 50% of the total battery industry and 70% of rechargeable batteries. Even the most developed countries and regions in the world, such as Europe, America and Japan, still have a large Production and use of lead-acid batteries. [0003] A lead-acid battery usually includes a battery case, a battery cover, and an electrode group inside the battery case. The electrode group is the core component of a lead-acid battery. It includes several overlapping positive and negative pl...

AI Technical Summary

Problems solved by technology

Compared with manual casting and welding, it can be seen that the production efficiency of automatic casting and welding is higher, but the quality of busbar casting and welding is related to the thickness of tabs, alloy types, mold temperature, lead temperature, welding time, cooling time, tin immersion, and tab cutting brush. The effect and the use of flux are closely related. There are many process parameters that need to be controlled. Errors in any link will cause quality problems in casting and welding. If the time is too short and the pretreatment is not in place, it will lead to false welding, false welding and missing welding of the tabs; correspondingly, the structure of this automatic casting welding machine is also relatively complicated. The fixtures, molds, casting liquid, cutting brush ears, These consumables and wearing parts of the heating tube will increase the cost and greatly increase the energy consumption
