New energy lithium battery BMS-Insulating Reliability for Every BMS

• Full in-line automation: Automatic lifter → Automatic feeding conveyor → Conformal coating machine → Sealing inspection conveyor → UV curing oven → Automatic flipping machine → Conformal coating machine → Sealing inspection conveyor → UV curing oven → Automatic lifter
• Lower rotary track design: Dual-layer track (upper production, lower return) optimizes workshop space and material flow efficiency
• Double-side conformal coating: Flipping machine enables top & bottom PCB coating, ideal for high-density BMS boards with components on both sides
• High-precision conformal coating: ±0.02mm repeatability via servo + ball screw drive, precisely avoiding connectors, high-voltage terminals and sensitive BMS components
• UV curing system: Dual UV curing ovens for fast, deep cross-linking, forming a durable coating resistant to high temperature, humidity, vibration and electrical corrosion
• Flexible PCB handling: Electric rail width adjustment (50–450mm), fits various BMS PCB sizes (power battery BMS, energy storage BMS modules)
• Multi-mode coating: Dot/line/curve/area spraying, eliminates shadow effect for uniform edge coverage on complex BMS PCBs
• SMEMA compatible: Standard SMEMA interface for seamless integration with SMT assembly lines
• 24/7 production stability: Industrial-grade design for mass manufacturing of new energy BMS components

This New Energy Lithium Battery BMS Automatic Conformal Coating Line is a tailor-made solution for new energy manufacturers, addressing the high-reliability and safety demands of power battery BMS, energy storage BMS and other lithium battery management system PCBs.

The entire line integrates automatic lifting, feeding, conformal coating, sealing inspection, UV curing, automatic flipping, secondary conformal coating, secondary sealing inspection, secondary UV curing and unloading modules, with a lower rotary track for material return, realizing a closed-loop automated double-side coating production flow. The core conformal coating machine adopts a high-precision servo + ball screw drive system with ±0.02mm repeatability, which accurately applies protective coating only to the required areas of BMS PCBs, avoiding high-voltage terminals, communication interfaces and sensitive control components—effectively reducing material waste and eliminating the need for manual masking.

The automatic flipping machine is a key highlight for double-side BMS PCBs: it safely flips the PCB 180° after the first coating and curing pass, enabling precise coating of the bottom side components. Dual sealing inspection conveyors detect coating integrity, pinholes and leakage after each coating pass, ensuring the coating fully isolates high-voltage circuits and prevents short circuits or electrical corrosion in harsh new energy operating environments (high temperature, humidity, strong vibration, electrical corrosion). Dual UV curing ovens provide fast, deep cross-linking, quickly solidifying the coating to form a dense protective layer that withstands long-term thermal stress, mechanical vibration and extreme environmental corrosion, extending the service life of BMS systems and meeting international safety standards for new energy lithium battery products.

With a standard SMEMA interface, the line can be seamlessly connected to existing SMT production lines. The compact layout (L9740mm × W1350mm) and lower rotary track design optimize workshop space utilization, while the flexible programming (manual teaching + mouse-keyboard input) supports quick product changeovers for multi-type BMS production. This solution not only improves production efficiency by over 300% compared with manual coating, but also reduces the defective rate to below 0.1%, helping manufacturers meet the reliability and safety requirements of global new energy markets.
