Basic Welding Process of Polymer Battery

The welding and processing method of polymer battery is mainly one of the methods used in a battery production line. It can not be one of the general welding methods for a certain type of battery, so that new employees can quickly make qualified batteries according to the basic welding method of polymer lithium battery. This situation will be encountered in the process of new employees' induction training. If there is practical field operation, it must be completed first For trial use, the factory will give a certain opportunity to test the wrong tin.

In the welding method of polymer battery, it is pointed out that the operator should check whether the battery combination is correct after getting the model of polymer battery, and confirm again that the PCB lead wire is welded correctly. According to different battery models, the battery house should weld the two ends of the connecting wire on the welding point of PCB and the combination battery according to the method shown in the left figure, and pay attention to the red and black lines; during welding, pay attention not to short circuit, polymer battery In general, the PCB welding points shall be free of burr, faulty welding, cold welding and other defects; the static ring shall be worn, Prepare the processed PCB, assembled battery, tin wire and soldering iron; check whether the welding point is firm and free of bad phenomena such as faulty welding, burr, too large tin package, etc., and flow down the process after confirming that it is OK to ensure that the tin package of polymer battery model is smooth and the tin tip, faulty welding, cold welding, etc. are bad; the tin must be wrapped with the wire core, but the tin water cannot be got on the insulation rubber of the lead wire.

Key points of basic welding method for polymer lithium battery: first, check whether the electronic components on the PCB are damaged, whether there is black barley on the back, whether the leads are damaged, scalded, and whether the welding method is even with tin, OK, then weld 1007 / 24 × 17, × 25, × 17, and × 40 mm red and black leads on the V4, V3, V2, and b-welding points of the PCB; then weld the red and black leads on the other plug of the battery model on the PCB For the P + and p-welding points of the lithium polymer battery, the welding method prompts you to pay attention to the plug lead not to be welded reversely. Specifically, we do the battery welding method or see the sample plate. After the polymer battery model is welded, pay attention to check that the welding points are free of burr, faulty welding, cold welding, scald, reverse welding and other defects. Confirm that OK flows to the next process.

Most of the welding methods of each polymer battery are the same, for example, the soldering processing and welding of a single polymer battery are basically the same, but there are great differences in many parallel and multi string soldering connection methods, including the sampling line connection line, etc., which can not be welded wrongly, otherwise it is easy to cause danger.
