Problems solved by technology

[0002] In the welding of the conductive end of the lead-acid battery, most of the modern technologies are cast welding, and it is heated and melted with a high-flow flame gun. For lead with a low melting point, there are many problems: not only Lead vapor is produced, polluting the air environment and causing harm to the human body; moreover, the conductive terminals and the electrode plates are not completely melted together, and even air gaps and oxide films are generated, which greatly increase the internal resistance of the battery

Abstract

The invention discloses a welding device for the connection end of a lead-acid storage battery, which comprises a friction welding machine, an electrode plate assembly box, a welding jig and a lifting transmission device. The lifting conveying device is arranged inside the bracket and at the lower part of the electrode plate assembly box, the two sides of the welding fixture are provided with guide rails for conveying the electrode plate assembly box, and the friction welding machine is arranged outside the bracket. The invention adopts the welding method of friction stir welding to well control the heat input in the welding process, only heat the welding part to the plastic state to carry out welding, and lead vapor will not be generated, the production environment is improved, and the battery capacity is reduced. Increase internal resistance and increase battery life, while realizing automated production.

Description

technical field [0001] The invention relates to the technical field of storage battery welding, in particular to a welding device for connecting ends of lead-acid storage batteries. Background technique [0002] In the welding of the conductive ends of lead-acid batteries, most of the modern technologies are cast welding, and the flame gun with high air flow is used for heating and melting. For lead with a low melting point, there are many problems: not only Lead vapor is generated, polluting the air environment and causing harm to the human body; moreover, the conductive terminals and the electrode plates are not completely melted together, and even air gaps and oxide films are generated, which greatly increase the internal resistance of the battery. [0003] Therefore, it is necessary to improve the welding process of the conductive end of the battery, improve the production environment, reduce the internal resistance of the battery, increase the service life of the batter...
