Lithium battery & semiconductor precision equipment project

I. Project Overview

A South Korean manufacturer of new energy and semiconductor equipment required precision drive units for machinery used in lithium-ion battery winding, electrode coating, wafer inspection, and packaging platforms. Operating in a cleanroom environment, the equipment demanded micron-level positioning accuracy and continuous 24/7 precision motion; all critical motion axes utilized our company's ultra-Precision Planetary Gearboxes.

II. Project Challenges

1. Standard gearboxes exhibited excessive backlash; switching between forward and reverse rotation caused transmission play, leading to fluctuations in electrode tension and wafer alignment errors, which directly impacted the yield rates of battery cells and chips.

2. Under high-speed, high-frequency start-stop conditions, insufficient gearbox rigidity caused micro-vibrations, resulting in minute scratches on films and wafers and a high risk of scrapping high-end products.

3. Cleanroom standards strictly limit grease volatilization and particle shedding; traditional lubrication methods tended to release trace volatile compounds, compromising the cleanroom's cleanliness rating.

4. During prolonged precision operation, standard gearboxes experienced significant temperature rises and accuracy degradation over time, necessitating frequent equipment recalibration.

III. Solution

1. Ultra-precision, zero-backlash Planetary Gearboxes featuring ultra-high torsional rigidity eliminated transmission play during directional changes, stabilizing electrode tension and wafer alignment accuracy.

2. Gear manufacturing processes designed for low vibration and low heat generation suppressed micro-jitter during high-speed motion, preventing scratches on precision materials.

3. Specialized long-life cleanroom grease—characterized by low volatility and zero particle shedding—met cleanroom production standards and ensured no contamination of precision components.

IV. Optimized heat dissipation design kept temperature rise under control during continuous operation and minimized accuracy degradation over long-term use, thereby reducing the need for repeated equipment recalibration. IV. Project Value

1. Transmission backlash and vibration issues are thoroughly resolved; yield rates for core lithium-ion battery and semiconductor products are steadily increasing, while material waste costs for high-end components are reduced.

2. Clean-room compatible design meets cleanroom standards, eliminating the need for additional isolation or protective structures and simplifying the overall equipment design.

3. Excellent temperature rise control ensures stable precision during long-term continuous production; the frequency of equipment downtime for recalibration is significantly reduced, effectively boosting equipment utilization rates.

4. Meets high-end precision standards for the lithium-ion battery and semiconductor industries, helping customers supply equipment to leading South Korean new energy and chip manufacturing plants and expand into high-end overseas markets.
