Automatic Conformal Coating Line for Photovoltaic Inverter & Energy Storage PCBs with Sealing Inspection & IR Curing

Quick Details:

• Full in-line automation: Automatic feeding conveyor → Conformal coating machine → Sealing inspection conveyor → IR curing oven → Inspection & collection conveyor
• High-precision conformal coating: ±0.02mm repeatability via servo + ball screw drive, precisely avoiding PV inverter/energy storage PCB connectors, high-voltage terminals and sensitive components
• IR curing system: Uniform infrared curing for strong coating adhesion, resistant to high temperature, humidity, salt fog and electrical corrosion in outdoor PV/energy storage scenarios
• Flexible PCB handling: Electric rail width adjustment (50–450mm), fits various PV inverter/energy storage PCB sizes (on-grid/off-grid inverters, BMS boards, energy storage modules)
• Multi-mode coating: Dot/line/curve/area spraying, eliminates shadow effect for uniform edge coverage on high-density power PCBs
• SMEMA compatible: Standard SMEMA interface for seamless integration with SMT assembly lines (pick-and-place, reflow oven, AOI)
• Built-in inspection & collection: Final inspection and automatic collection station for quality control and finished product sorting
• 24/7 production stability: Industrial-grade design for mass manufacturing of PV inverter & energy storage components

This Photovoltaic Inverter & Energy Storage Automatic Conformal Coating Line is a tailor-made solution for renewable energy manufacturers, addressing the high-reliability and safety demands of on-grid/off-grid PV inverters, battery management systems (BMS), energy storage modules and other power electronics PCBs.

The entire line integrates automatic feeding, conformal coating, sealing inspection, infrared curing and final inspection/collection modules, realizing a fully automated production flow from loading to unloading. 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 PV/energy storage PCBs, avoiding high-voltage terminals, communication interfaces and sensitive control components—effectively reducing material waste and eliminating the need for manual masking.

The infrared curing oven provides uniform and stable heating, quickly solidifying the coating to form a dense protective layer that withstands long-term thermal stress, electrical corrosion and extreme weather conditions, extending the service life of PV inverters and energy storage systems and meeting international standards for renewable energy equipment reliability.

With a standard SMEMA interface, the line can be seamlessly connected to existing SMT production lines. The compact layout (L6760mm × W1350mm) optimizes workshop space, while the flexible programming (manual teaching + mouse-keyboard input) supports quick product changeovers for multi-type PV/energy storage 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 renewable energy markets.
