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.

The core equipment for grinding lead ball into lead powder adopts ball milling process, with stable production capacity and uniform particle size, which is the first process of polar plate production.

Pour the lead alloy molten liquid into the plate grid, adopt high-precision mould and automatic temperature control system, the plate grid has good weight consistency and high production efficiency.

The auxiliary materials of lead powder, acid and water are mixed according to a certain proportion, which is easy to operate and low in maintenance cost, and suitable for small and medium-sized production.

Apply the lead paste on the grid surface continuously and evenly, with accurate and controllable paste amount.
