Assembly line

Wrap and package the positive and negative electrode plates with separator paper (PE or AGM separator) to prevent short circuits between the positive and negative electrodes, which is a key pre assembly process on the assembly line

Connecting the pole group and busbar through casting welding process, with firm welding and low resistance, is the core equipment of battery assembly.

Perform high-voltage insulation testing on the electrode group after casting and welding to ensure that there is no short circuit hazard inside the electrode group and improve the safety performance of the battery.

Connect the pole groups between adjacent cells through wall welding to form a series circuit, and the welding quality directly affects the internal resistance of the battery.

Online detection of battery internal resistance, rapid screening of defective products, ensuring that the internal resistance of each battery meets the standard.

By heating with a hot plate, the battery cover is heat sealed and bonded to the battery compartment, ensuring reliable sealing and preventing battery leakage.

The battery terminals and poles are fixed by high-temperature welding, which has good conductivity, high connection strength, and strong durability.

Perform air tightness testing on the battery after heat sealing the large cover to ensure that the seal is qualified and eliminate the risk of leakage.

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.

Laser marking of production date, batch, barcode and other information on the battery casing, with permanent and clear markings for easy traceability throughout the entire process.
