The lead-acid battery has become one of the most widely used chemical batteries, which is currently used by low, low-cost, low capacity, simple capacity, simple performance, reliable and adaptability. Lead-acid battery pack production includes a plate weighing group, a packaged plate, a polar welding, a polar group, a polar plate test, and other multiple steps, with a polar welding is a key step in the lead-acid battery assembly process, It directly affects the quality and performance of lead-acid batteries.The lead-acid battery assembly pole welding refers to the process of forming a plate and the separator assembly, and the process of forming a bus bar is integrated, and the positive electrode group can be formed after welding the positive group welding. Negative group. Therefore, the lead-acid battery assembly requires polar welding, no durable welding, fake welding, no lead. The polar welding can be divided into two methods of gas welding and casting welding.
The gas welding is a method of melting the welding and electrodes using the high temperature produced by combustible gas mixing with oxygen mixed with oxygen. When the lead-acid battery pole is welded, the weldment is a pole and a pole column, and the electrode is a preformed alloy member for a lead-based alloy. The flammable gas is mainly acetylene gas and oxygen mixed combustion. The flame produced is called oxygen flame. Methods of gas welding with oxygen flames are called oxygen flame welding. The oxygen flame is generally achieved by a torch, and the gas welding process is a flame that is discharged from the torch. The welding of the solder is heated to the melting state and form a molten pool, and then fuse the welding to the welding rod to fill the welding. One.
The quality of the battery pole is mainly depends primarily on the temperature of the lead liquid pool, casting and mold. With the intelligent PID temperature controller with parameters self-checking, the temperature of the casting welding is PID control, and the control accuracy is always maintained within ¡À 2 ¡ã C, ensuring the quality of the polarized casting process; using PLC control technology, casting Co-control control of the cylinders and motors of the welder during the working process of the welding machine, and automate production of lead-acid battery packs.
