[0002] The rapid development of new energy batteries has driven the replacement of pouch batteries with steel-cased consumer batteries, giving them higher performance, higher density, and higher safety. In the new energy consumer battery sub-sector, due to the huge market capacity and increased production volume of this emerging industry, the demand for this component has risen sharply. To improve safety and production efficiency, helium testing is essential throughout the entire production process.
[0003] However, existing technologies for inspecting steel-cased battery covers fall short of expectations, particularly in ensuring product yield and controlling safety risks. Specifically, most equipment currently on the market for inspecting the welding quality of steel-cased battery covers suffers from significant deficiencies in accuracy and reliability, and its limited testing structure makes it difficult to ensure that every inspected product meets high-quality standards. This not only impacts production efficiency but also leads to a high defect rate, increasing production costs for companies.
[0004] Because defects are not detected in a timely and accurate manner, the manufactured battery products may have safety hazards such as leakage and short circuits during use, which greatly increases safety risks and poses a huge threat to the life and property safety of users.
[0005] Therefore, the above situation urgently needs to be addressed. Utility Model Content
