Application of contact angle measuring instrument in new energy industry

2022-04-18

Nowadays, new energy vehicles are rapidly emerging around the world, and the quality of lithium batteries is becoming more and more stringent. Therefore, in order to ensure the quality of lithium batteries, advanced testing technology is required in the production process; There will be contaminants such as oil stains, fingerprints, dust, etc. If the surface of the parts is not thoroughly cleaned before welding, the hydrocarbons in the oil stains will be separated during welding, causing porosity defects and splashing during the welding process. In addition to the characteristics of the material itself, it is also related to the poor surface cleanliness, which is also one of the main reasons for welding quality problems. Therefore, plasma cleaners and contact angle measuring instruments are usually used for processing and testing. .

Lithium batteries with large capacity have high requirements for welding process, so before the welding process of electrodes, Pack shells and circuit boards, Sindin's precision plasma cleaning machine can be used to clean the surface cleanliness.

Then, the contact angle of the surface is measured by Sindin's precision contact angle measuring instrument to judge the cleaning effect, so as to effectively avoid defects such as pores, cracks, explosions, desoldering, and virtual welding in welding, and also efficiently assist the production department to stabilize The cleaning quality of the substrate, the optimization and improvement of the production process of lithium batteries, improve the work efficiency and reduce the defect rate.
