Lead-acid battery electrode group welding process

Abstract

The invention discloses a lead-acid battery pole group welding technology. After a pole group is conveyed to a pole group arranging area, a lug positioning structure positions lugs, and posts and lead bridges are placed; a pole group welding module reciprocating driving unit makes a pole group welding module in the pole group arranging area move to a pole group welding area as a whole, meanwhile, another pole group welding module originally located in a pole group welding area is moved to the pole group arranging area under driving of another pole group welding module reciprocating driving unit, and the pole group welding module reaching the pole group arranging area completes pole group arranging work; after the pole group welding module reaches the pole group welding area, a three-axis numerical control mechanism and a fire gun nozzle start to work. At the time, the pole group welding module in the pole group arranging area completes arranging movement, and the two pole group welding modules exchange positions under driving of the pole group welding module reciprocating driving unit. The heating fusion welding principle is adopted, production cost is low, production efficiency is high, and welding quality can be controlled more easily.

Description

technical field [0001] The invention relates to a lead-acid battery manufacturing technology. Background technique [0002] The existing lead-acid battery commonly used cast welding method, the Chinese invention patent No. 201110003663.5 disclosed on May 4, 2011 a battery pole group cast welding machine, including a gap divider, the gap divider is provided with a rotating Workbench, the rotary table is provided with four pole group fixtures, the four pole group fixtures are evenly distributed at intervals of 90 degrees around the rotation axis of the rotary table, and the top of the rotary table corresponds to the four pole group fixtures There are four manipulator mechanisms, and a casting and welding mold is set under each manipulator mechanism, in which the pole group input mechanism is provided on the side of the first pole group fixture, and the lead furnace is installed under the second pole group fixture for the pole group For welding, a cooling device is provided un...

AI Technical Summary

Problems solved by technology

Due to the complex casting and welding process, the structure of the casting and welding machine is also relatively complicated, and the consumables and easy-to-use parts such as jigs, molds, casting liquid, cutting brush ears, and heating pipes used in casting and welding will increase the cost and greatly increase the energy consumption. Increase; practice has proved that the quality of cast welding is related to mold material, mold temperature, lead liquid temperature, welding time, cooling time, the effect of cutting brush ears, and the use of flux, so the quality is not stable and difficult to guarantee
