Post processing line

Weigh and test the total weight of the battery, mark and remove defective products. Qualified products are laser marked with production date, batch, barcode and other information on the battery casing, with permanent and clear markings for easy traceability throughout the entire process.

By simulating high current discharge conditions and monitoring real-time parameters such as voltage and current, it is an important testing equipment for detecting the high current discharge performance of lead-acid batteries before leaving the factory.

Wash the surface of the finished battery with water and dry it with hot air to remove residual acid and make the appearance clean and beautiful.

Perform secondary airtightness testing on the battery after heat sealing the small cover, double check the sealing quality, mark and remove defective products.

Heat seal the battery cover (exhaust valve cover) with the battery cover to prevent acid mist leakage and ensure sealing.

Online detection of battery acid level height, automatic judgment of whether it is qualified, and automatic marking or removal of non-conforming products.

Accurately adjust the electrolyte level inside the battery to the standard height, ensuring that the liquid level of each individual cell is consistent.

Inject the electrolyte accurately according to the set amount, and optional vacuum acid addition process can fully immerse the electrolyte into the micropores of the electrode plate to ensure battery capacity.

The excess electrolyte inside the battery after formation is drained and recycled to reduce acid consumption and minimize environmental treatment costs. This process is suitable for secondary acid addition techniques.
