SMARTWIN Encoders Empower New Energy Manufacturing: From Micron-level Alignment to Zero Downtime

SMARTWIN Encoders Empower New Energy Manufacturing: From Micron-level Alignment to Zero Downtime

In core new energy processes including lithium battery electrode stacking, high-speed PV series welding and motor stator-rotor assembly, production equipment needs to achieve micron-level positioning within short strokes, along with frequent start-stop and reversing movements hundreds of times per minute. Although traditional optical encoders feature high precision, they are highly susceptible to dust, oil contamination and temperature fluctuations. Carbon powder in electrode coating workshops and high-temperature radiation near PV welding machines easily cause signal fluctuation or even complete encoder failure. Incorrect position feedback will lead to defective products at the least, and full production line shutdown at worst, causing tens of thousands of yuan in losses per minute for new energy manufacturers. In addition, new energy production lines operate 7/24 non-stop, which requires encoders to support absolute position memory and eliminate tedious homing procedures after power failure. These stringent requirements drive the industry to adopt smarter encoder solutions. SMARTWIN Intelligent Equipment deeply integrates linear motors with high pollution-resistant absolute encoders, delivering motion feedback solutions featured with dust resistance, power-off position memory and consistent micron-level precision for new energy equipment.

The encoders adopted by SMARTWIN adopt non-contact reluctance and inductive sensing principles together with specialized sealing structure, reaching protection grade up to IP67 and even IP69K. It maintains stable position signal output even when the encoder reading head is covered with thin graphite dust generated during lithium battery electrode cutting. Unlike glass linear scales, it suffers no precision drift caused by thermal expansion or micro-cracks under high temperature and vibration of photovoltaic string welding equipment. Equipped with multi-turn absolute position function, it permanently stores motor position data after power failure. After temporary power outage or routine maintenance, the equipment can resume production directly without homing, saving 5 to 10 minutes of reset time each downtime, which brings prominent benefits to lithium battery winding workshops with frequent start-stop operations. In terms of precision, its resolution reaches 1μm or even 0.1μm. Matched with SMARTWIN high thrust density linear motors, it keeps electrode alignment error of battery stacking machines far better than the mainstream industry standard of ±5μm. Furthermore, via high-speed real-time communication protocols including BiSS, SSI and EtherCAT, the encoders synchronously transmit multi-dimensional data such as position, speed, temperature and vibration to upper-level AI systems, laying solid data foundation for predictive maintenance and automatic process optimization of lithium battery manufacturing equipment.

By deeply integrating linear motors and encoders, SMARTWIN Intelligent Equipment not only solves the long-standing drawbacks of traditional encoders such as vulnerability to dust, vibration and power outage, but also equips domestic new energy equipment with core component advantages in high-speed and high-precision manufacturing. In the future, high-performance encoders are expected to become standard configurations for lithium battery, photovoltaic and energy storage equipment. As a professional system solution provider, SMARTWIN is steadily underpinning the efficiency revolution of green intelligent manufacturing.
