Description

Battery end melting processing device

This creation is a battery end melting processing device, which involves battery production and processing technology. It aims to allow the soldering iron tip of the processing device to be immersed in the hot-melt tin liquid to isolate the air, preheat and adhere to the hot-melt tin liquid. The terminals of the battery and the poles or two adjacent bridges are welded to form an electrical connection, which improves the yield of battery conduction.

As shown in the first and second figures, a general storage battery 1 includes a plurality of battery pole groups 100 and a accommodating box 200. The accommodating box 200 is divided into a plurality of accommodating spaces 201 by partitions arranged at a plurality of intervals. A set of battery pole groups 100 is placed in the containing space 201, and each containing space 201 is filled with acid solution, thereby generating a chemical reaction with the battery pole group 100 to achieve the effect of electric energy conversion.

Each battery pole group 100 includes a plurality of positive and negative plates arranged at intervals, and a bridge 101 arranged above the plurality of positive and negative plates. After welding or welding two oppositely arranged bridges 101, the plurality of battery electrode groups can be made 100 electrical joints. In the plural battery pole groups 100, in addition to the bridge 101, the two battery pole groups 100 are respectively provided with a pole 102, and the top of each pole 102 can be welded to a terminal 103 located outside the accommodating box 200, After the two terminals 103 are electrically connected to the external power supply, the multiple battery pole groups 100 can be charged through the two terminals 103, the positive and negative poles 102 and the bridge 101.

In the above structure, the quality of welding will affect the conductivity of the battery. The current automatic welding method is to use a welding gun to heat the solder, and then use the molten solder to weld the terminals 103 and the pole 102, and the bridge 101 to each other to achieve electrical Splice. However, after soldering, tin beads will remain on the surface of the soldering iron tip of the welding gun, which will affect the quality of the next welding. Therefore, there is an air nozzle on the automatic machine. The air nozzle can blow high-speed air to remove the tin beads on the soldering iron tip. Facilitate the next welding operation.

However, blowing and removing the tin beads with a gas nozzle will not only cause the tin beads to fall off, but also cause the temperature of the soldering iron tip to drop. The soldering iron tip needs to be heated again to increase the temperature to the temperature that can fuse the solder before the soldering operation can continue. Automated processes that affect welding.

Furthermore, due to the choice of material, the surface of the soldering iron tip is prone to generate oxides, which makes the soldering iron tip less likely to be stained with molten tin. Therefore, the soldering iron tip needs to be coated with a thin layer of solder after use to reduce the chance of oxidation of the soldering iron tip. Welding is easier to succeed, but at present, in the welding process, there is no better automatic anti-oxidation step for the soldering iron tip, which shows that there is still room for improvement in the welding process.

In view of this, the creator has accumulated many years of research and practical experience in related fields, and specially created a battery end melting processing device to improve the automatic soldering process. The air nozzle is used to remove the tin beads, which causes the temperature of the soldering iron tip to drop. The problem of automatic manufacturing process and easy oxidation of the soldering iron tip.
