Electrode Fabrication Machine

Electrode Fabrication Machine

Electrode fabrication machines are divided into positive electrode fabrication and negative electrode fabrication machines. Both involve placing rolled electrodes, tabs, and adhesive tape onto the equipment, and then performing welding, tab cutting, adhesive application, and finally rewinding or cutting into sheets. The main processes include electrode unwinding, tab unwinding, tab feeding and cutting, tab feeding and welding, electrode adhesive application, and rewinding or cutting. They are available in 2/4/6/8-stage adhesive application machines based on the number of adhesive application stations.

Industry Challenges

Insufficient System Stability:
Insufficient equipment intelligence, overall machine uptime around 90%.

Insufficient Adhesive Application Accuracy:
Adhesive application accuracy is greater than ±0.5mm during constant speed operation; greater than ±1mm during acceleration/deceleration.

High Cost Pressure:
Primarily uses Japanese main control units, with multiple brands involved, resulting in high overall system cost.

Solution Features

Higher System Stability:
By adding an automatic tape-feeding program and motion memory after manual/automatic switching, rapid recovery from anomalies is achieved. Relying on product stability, the average uptime of the entire machine is currently greater than 98%.

Superior Adhesive Application Accuracy:
Adhesive application accuracy is ≤±0.2mm during both constant speed and high/low speed switching.

One-Stop Service:
Customized 6-channel probe servo drive for the lithium battery industry, resulting in a more cost-effective and efficient system.

Value Realized

Uptime is increased by over 10% through program optimization.

Adhesive application accuracy is improved from ±0.5mm to ±0.2mm, a 60% improvement.

Cost is reduced by over 30% compared to foreign brands.
