The new energy revolution is fueled by the power and reliability of lithium-ion batteries. As the demand for electric vehicles (EVs) and energy storage systems soars, battery manufacturers face immense pressure to enhance production efficiency, precision, and above all, the consistent quality of every cell. At the heart of this high-stakes manufacturing process lies advanced machinery requiring drives of exceptional accuracy, durability, and stability.
A leading manufacturer of battery electrode coating and calendering equipment was grappling with significant challenges. Their machinery, critical for producing uniform anodes and cathodes, suffered from inconsistent tension control, slight speed variations in rollers, and unplanned downtime due to drive system maintenance. These issues directly impacted electrode coating homogeneity and sheet density, leading to minute defects that compromised battery capacity, lifecycle, and overall performance—an unacceptable risk for their EV OEM clients.
Recognizing that the drive system was the key to unlocking higher quality, they partnered with us. Our engineering team conducted a thorough analysis and deployed a tailored motion solution centered on our PX Series Precision Planetary Reducers and PTN Series Hollow Rotary Platforms.
The Integrated Solution & Its Impact:
1. Superior Tension and Speed Control in Coating Lines: Our PX Planetary Reducers were integrated into the coating and drying sections. Their high torsional stiffness and minimal backlash ensured perfectly synchronized and smooth rotation of the guide rollers. This eliminated minute speed fluctuations, enabling precise control of the thin electrode foil's tension throughout the process. The result was an exceptionally uniform coating application, a critical factor for maximizing energy density and preventing hot spots.
2. High-Precision Positioning in Calendering & Slitting: The PTN Hollow Rotary Platforms were installed in winding and indexing stations. Their hollow-shaft design allowed for seamless integration of electrical cabling and vacuum systems for material handling, simplifying machine design and reducing maintenance. Combined with high positional accuracy and zero backlash, the PTN platforms ensured flawless winding alignment and precise slitting of electrodes, drastically reducing material waste and edge defects.
3. Unmatched Reliability for 24/7 Operation: Lithium battery production runs continuously. The robust design of both the PX and PTN series, built for high load capacity and operational stability, ensured unwavering performance under constant load cycles. Their low maintenance requirements and minimal acoustic noise contributed to higher overall equipment effectiveness (OEE) and a better factory environment.
Results Delivered:
By adopting our PX Reducers and PTN Hollow Platforms, the equipment manufacturer achieved a transformative upgrade:
