Solder-wire-free high-frequency automatic welding method for storage battery connecting piece

Abstract

The invention discloses a solder-wire-free high-frequency automatic welding method for a storage battery connecting piece. The connecting piece is sleeved by a battery binding post exposed out of the head end of a storage battery, the storage battery is fed to a soldering flux adding station through a conveying mechanism of a high-frequency automatic welding machine, a soldering flux adding mechanism applies a soldering flux on the head end of the battery binding post and the connecting piece, a workpiece moving mechanism enables the storage battery to be moved to a station to be welded, and a welding mechanism descends to enable a welding coil to be located above the head end of the battery binding post. A high-frequency power supply generator of the welding mechanism takes the effect, the welding coil connected with the high-frequency power supply generator produces an induced magnetic field, an energy-gathered core placed in the welding coil gathers the high-frequency magnetic field at the head end to enable the head end of the battery binding post body to produce high temperature and be rapidly molten into molten lead, the molten lead flows down, cools down to be welded with the connecting piece, and then the storage battery is sent out through the conveying mechanism. The welding method enables the welding quality and machining efficiency to be high, does not need solder wire materials, saves the cost, saves manpower and material resources and creates great economic benefit.

Description

technical field [0001] The invention relates to a high-frequency automatic welding method for battery connecting pieces without welding wire, and belongs to the field of battery connecting piece welding methods. Background technique [0002] The lead-out end of the pole group of the battery is the battery terminal. After passing through the hole provided on the upper cover of the battery installation box, the connecting piece used to connect to the external power supply is placed on the battery terminal, and then Use electric soldering iron and solder wire to act on the battery terminal, so as to weld the battery terminal and the connecting piece together. There are several deficiencies in this welding process: the worker holds an electric soldering iron for welding, and the welding quality depends entirely on the worker's automatic welding method.

Problems solved by technology

There are several deficiencies in this welding process: the worker holds an electric soldering iron for welding, and the welding quality depends entirely on the worker's automatic welding method. The quality of welding fluctuates greatly, and the welding quality is difficult to guarantee; It is necessary to use solder wire for welding, which increases the economic expenditure of the enterprise; in addition, manual welding produces a large amount of harmful gas, which causes serious injury to the welder's body; the production efficiency is low, and the welding time for each battery with 2 welding points is about 10S
