In the “TWh era” of the new energy vehicle industry, power battery manufacturers face an unprecedented dual challenge: ensuring extreme product safety while pursuing peak production efficiency. As the first line of defense in battery packaging, the sealing integrity of the power battery cover plate determines whether a cell will suffer from electrolyte leakage or thermal runaway.
So, how do leading Tier-1 factories maintain high-speed output of ≥12PPM (12 pieces per minute) without compromising on detection sensitivity? The answer lies in the deep integration of the automatic vacuum box helium leak detection system.
Automation Integration: Eliminating Production Bottlenecks
Traditional leak testing methods often rely on manual operation, which is not only slow but also prone to human error. The system developed by Anhui Bowei utilizes a dual-station parallel detection scheme, allowing for a seamless coordination between loading, unloading, and the testing process.
By integrating advanced PLC control and optional robotic manipulator loading and unloading, the entire cycle—from vacuum pumping and helium injection to leak analysis and gas recovery—is fully automated. This configuration eliminates “inspection bottlenecks” and is a critical component for scaling up lithium battery production lines efficiently.
1×10^-9 Pa·m3/s Precision: Redefining Safety Standards
For power batteries, microscopic pores or cracks can evolve into catastrophic failures under long-term vibration. This system employs helium mass spectrometry leak detection technology, achieving a minimum detectable leak rate of 1×10^-9 Pa·m3/s.
As a tracer gas, helium is inert, safe, and possesses a low molecular weight with high permeability. Compared to traditional water bubble tests or pressure decay methods, vacuum box helium leak testing is several orders of magnitude more accurate and qualifies as non-destructive testing (NDT), ensuring every cover plate meets stringent international quality control requirements.
Efficiency Meets Economy: Lowering Long-term Operational Costs
When procurement managers evaluate the vacuum box helium leak detector cost, the initial investment is only part of the equation. The true advantage of the Bowei system is its highly efficient helium recovery system. By recycling expensive helium gas, it significantly reduces the cost per tested component.
Furthermore, a high-speed beat of ≥12PPM means more qualified products are produced in the same timeframe, reducing the scrap rate and the risk of costly post-market recalls.
Conclusion
As the industry pushes for higher energy density and longer cycle lives, high-efficiency leak detection equipment has become a core competitive advantage. Investing in an automatic battery cover plate leak detection system is not just a technical upgrade—it is a strategic investment in brand reliability and manufacturing excellence.
