Busbar cast welding device for lead-acid storage battery

Abstract

The invention discloses a busbar cast welding device for a lead-acid storage battery, comprising a lead smelting furnace, a demouldng and box-feeding machine and a workpiece conveyor, wherein the workpiece conveyor is a rotary conveyor, a turntable of the workpiece conveyor is uniformly provided with four lifting frames respectively provided with a busbar cast welding mold with a cooling jacket, four working stations are arranged around the turntable, the lead smelting furnace is positioned on the first working station, and the demoulding and box-feeding machine is positioned on the fourth working station. The cast welding device disclosed by the invention has a compact and reasonable integral structure, and workpieces are conveyed by adopting a 3600 rotary conveyor for four-working station operation, wherein the second and the third working stations are vacant and serve as cooling intervals after busbars are subjected to cast welding; and meanwhile, a cooling water feeding device of a mold jacket on each lifting frame of the rotary conveyor is skillfully designed, thereby efficiently cooling the busbar subjected to cast welding in the mold with cooling water, changing the traditional air cooling mode with high energy consumption and numerous and complex equipment, greatly shortening cooling time, decreasing turnover molds, improving production efficiency and reducing production cost.

Description

Technical field [0001] The invention relates to a casting and welding device for connecting a bus plate of battery metal plates. Background technique [0002] Lead-acid batteries usually have a pole group composed of several positive plates and several negative plates. The positive plate tabs and the negative plate tabs in the pole group are respectively connected by a busbar, and then lead to the positive and negative terminals. In the manufacture of lead-acid batteries, the traditional method of connecting the electrode plate and the bus plate is manual welding. This method is time-consuming, labor-intensive, low-efficiency, unreliable, and the operating environment is highly polluted, which seriously harms human health. For this reason, some companies have developed special casting and welding devices for pole plates and busbars. For example: Patent No. CN200720149023.4 "Small Dense Casting Welding Machine", which includes a shaping machine, a headset, a lead melting furnace,...

AI Technical Summary

Problems solved by technology

The above-mentioned patents have realized the mechanization or semi-mechanization of casting and welding of the pole plate and the manifold, effectively solving the problems of high labor intensity, low work efficiency and large environmental pollution of the original manual welding.

However, there are still problems in both of which need to further improve work efficiency, reduce energy consumption and production costs. For example, the former has problems such as slow air cooling speed, high energy consumption, many turnover molds, and high production costs; the latter has problems such as casting Welding to demolding only takes one station, that is, only rotates 90°, so the cooling time is insufficient, and it is necessary to wait for cooling at the demoulding station, which affects work efficiency and output
