Why is plasma cleaning needed during laser welding of power battery cells?
2022-03-11
Power battery packs require frequent charging and discharging, so the reliability of their products is highly demanded. They must discharge stably and ensure that the welding wires are not corroded or fall off. This is especially important for battery systems used in vehicles, where the reliability of battery welding quality needs more attention. Today, we are discussing the plasma cleaning system, which is actually a cleaning process for the welding components before battery welding, increasing the adhesion of the weld and making it more solid and reliable. Therefore, we can summarize the application of plasma cleaning in battery module welding into three key reasons!
1. When automating the assembly and welding of power battery modules, it is necessary to clean the cells, especially after handling the cell edge sealing or tab leveling. Plasma cleaning can remove organic substances and small particles, improving the reliability of laser welding.
2. The welding of the positive and negative tabs requires cleanliness. The tabs are metal strips that lead the positive and negative poles from the cell. In simple terms, the ears of the battery's positive and negative poles are the contact points during charging and discharging. Whether this contact point is clean will affect the reliability and durability of the electrical connection.
3. Plasma cleaning is needed when assembling the module end plates and side welding. It not only prevents dust and small particles from entering the battery module but also improves the reliability of the laser seam welding between the side plates and end plates.
The laser cleaning machine plays a refined processing role in module assembly. Although it seems to have a minor effect, it can often lead to quality and safety issues for the entire battery module. Therefore, as a manufacturer of laser welding production equipment for power battery modules, it is essential to provide users with reasonable technical support and configurations for these details. One should not obtain user orders by lowering the Price while neglecting quality assurance. Users should also not overlook the performance value of the equipment itself due to high prices.
