Charging pile - Durable Protection for Enduring Performance

Automatic Conformal Coating Line for EV Charging Pile PCBs with Sealing Inspection & IR Curing

Quick Details:

• Full in-line automation: Automatic Lifter → Auto feeding conveyor → Conformal coating machine → Sealing inspection conveyor → IR curing oven → Automatic Lifter
• High-precision conformal coating: ±0.02mm repeatability via servo + ball screw drive, precisely avoiding charging pile PCB connectors, high-voltage components and sensitive areas
• IR curing system: Uniform infrared curing for strong coating adhesion, resistant to high temperature, humidity and electrical corrosion in EV charging scenarios
• Lower rotary track: Dual-layer track design (upper production, lower return) to optimize workshop space and improve material flow efficiency
• SMEMA compatible: Standard SMEMA interface for seamless integration with SMT assembly lines (pick-and-place, reflow oven, AOI)
• Flexible PCB handling: Electric rail width adjustment (50–450mm), fits various charging pile PCB sizes (DC fast charging, AC slow charging boards)
• Multi-mode coating: Dot/line/curve/area spraying, eliminates shadow effect for uniform edge coverage on high-density power PCBs
• 24/7 production stability: Industrial-grade design for mass manufacturing of EV charging pile components

This Charging Pile Automatic Conformal Coating Line is a tailor-made solution for electric vehicle charging pile manufacturers, addressing the high-reliability and safety demands of DC fast-charging, AC slow-charging and on-board charging PCBs.

The entire line integrates automatic lifting, feeding, conformal coating, sealing inspection, infrared curing and unloading modules, with a lower rotary track for material return, realizing a closed-loop automated 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 charging pile PCBs, avoiding high-voltage terminals, communication interfaces and sensitive electronic 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 high temperature, humidity, dust and electrical corrosion, extending the service life of charging piles and meeting national standards for EV charging equipment reliability.

With a standard SMEMA interface, the line can be seamlessly connected to existing SMT production lines. The dual-layer track design (upper production, lower return) optimizes workshop space utilization, while the flexible programming (manual teaching + mouse-keyboard input) supports quick product changeovers for multi-type charging pile 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 safety and reliability requirements of global EV charging markets.
