Problems solved by technology

Although this invention replaces manual flame welding, it still uses a high-temperature furnace to melt lead and heat the mold to weld the tabs. The production process also cannot solve the environmental pollution of lead smoke and lead dust and the generation of lead slag, which is not a green production technology.

Embodiment 1

[0032] Embodiment one, such as figure 1 and figure 2 As shown, the tab of the pole group is provided with a circular through hole, the cold splice is a toothed cylindrical rod 8, the cold splice runs through the through hole on the tab, and the toothed part of the cold splice is pressed into the hole of the tab. through hole. Preferably, as figure 1 As shown, one end of the cold splice is tapered so that the cold splice can be inserted into the through hole of the tab. After the cold splice and the tab are installed in place, as shown in figure 2 As shown, the busbar 7 is formed by cutting off the redundant parts of the cold splicing parts.

Embodiment 2

[0033] Embodiment two, such as image 3 As shown, there is a V-shaped groove on the top of the tab of the pole group, and the cold splice is a V-shaped rod. The V-shaped rod is pressed into the V-shaped groove to realize the fitting of the cold splice and the tab, and then cut The redundant parts of the cold splicing parts constitute the bus bar 7 .

Embodiment 3

[0034] Embodiment three, such as Figure 4 and Figure 5 As shown, the cold splicing piece is a U-shaped bar. There are clip teeth on both sides of the groove of the U-shaped bar. The groove of the U-shaped bar wraps around the top of the tab, and the clip teeth are embedded in the side of the tab.

Abstract

The invention discloses a welding-free storage battery busbar structure and a manufacturing process thereof and relates to the field of lead-acid storage batteries. The welding-free storage battery busbar structure comprises a pole group and a cold splicing piece. The cold splicing piece is made of metal with the resistivity higher than that of lead; a tab of the pole group is provided with a through hole or an open groove; and the cold splicing piece is embedded into the through hole of the tab or is extruded and embedded to the groove of the tab to form a busbar. Or, the cold splicing pieceis provided with a through hole or an open groove; the tab is embedded into the through hole of the cold splicing piece or extruded and embedded to the groove of the tab to form the busbar; and the busbar is sealed by glue after being formed. According to the invention, the high-conductivity metal of which the resistivity is higher than that of lead is taken as the busbar of the lead-acid storagebattery instead of lead and lead-based alloy, so that gravimetric specific energy of the lead-acid storage battery is improved, and the material cost of the lead-acid storage battery is reduced; and amechanical extrusion and embedding connection mode is adopted to replace a hot melting manufacturing mode, so that clean production is achieved, and lead pollution in the traditional production process is avoided.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a welding-free battery bus bar structure and a manufacturing process. Background technique [0002] Most lead-acid batteries use 12V as a battery, and the interior is composed of 6 monomers. Each cell has a positive and negative plate group. The positive and negative plate groups need to be welded together in parallel. The current collectors are collectively referred to as busbars. In order to ensure the service life of lead-acid batteries and high-rate discharge characteristics, the commonly used busbar alloys are mainly welded by lead-tin alloys through hot melting. Because of the high resistivity of lead, the busbars Row design often consumes more lead to ensure the cross-sectional area. [0003] In the early days of the traditional lead-acid battery busbar, the packaged electrode groups were welded (welded) together with lead and lead alloys to form clusters and form curre...
