Product Description
Advanced DIP AOI Inspection System
The IST AI-4026 is a reliable inline AOI optical inspection solution designed specifically for PCBA plug-in assemblies prior to THT soldering. It integrates a high-precision color camera for real-time image capture and CNN deep learning algorithms for intelligent defect identification. The system accurately detects wrong components, missing parts, reverse polarity, misalignment and other common DIP process defects. Powered by deep learning technology, it resolves long-standing industry pain points of traditional inspection solutions, such as lengthy programming cycles and high false defect rates.
This AOI system integrates seamlessly into existing production lines with adjustable height and width settings, and supports full remote debugging. It accommodates PCBs up to 520×380mm and connects to MES systems for automatic report generation and production data synchronization. Overall, this PCB AOI inspection equipment effectively lifts production yield and maintains stable, uninterrupted operation for SMT and DIP manufacturing facilities.
Core Features
High-Precision Defect Detection
The AI-4026 optical inspection machine applies deep learning technology to achieve one-click component and joint recognition. Trained on massive industrial data sets, it drastically cuts setup time and reduces false alarm rates. The CNN visual algorithm simulates human visual judgment logic to adapt to diverse PCB types and component materials, making it ideal for fast, accurate pre-soldering quality inspection in high-mix production environments.
Efficient DIP Line Integration
This AOI optical inspection system supports both online and offline setup without halting production flow. Full programming for a new board takes only 10–20 minutes, and on-site debugging can be completed in 10–15 minutes. One-click program switching and file recall greatly accelerate product changeover. It automatically identifies resistors, capacitors, diodes, sockets and other standard through-hole components, with clear visual and audible alarm prompts for detected defects, perfectly matching fast-paced DIP production rhythms.
User-Friendly Operation
Built exclusively for plug-in component inspection, the AI-4026 optical inspection system features fuzzy recognition for color-ring components and polarity verification. It effectively filters out silk screen interference and accurately detects black components on black PCB substrates. The same-color detection technology ensures reliable identification of missing or reversed components even under low-contrast conditions. Its excellent generalization capability adapts to various component material types, minimizing missed detection in daily PCB AOI inspection tasks.
