Smart Buffer Pro | Automatic OK/NG PCB Buffer & Sorter for AOI Inspection Lines
Automatically separate & buffer OK/NG boards after AOI. PLC-controlled, touch screen buffer machine receives AOI signals, prevents jams, and integrates seamlessly into your SMT line. Reduce manual handling.
SHIHAO'S SmartBuffer Pro, the intelligent solution for automating post-AOI PCB handling. Installed directly after your AOI (Automated Optical Inspection) system, this robust buffer machine automatically receives inspection signals, physically separates OK (good) boards from NG (bad/reject) boards, and stores them in designated buffers—all without manual intervention. By eliminating this bottleneck, it increases line throughput, prevents mixed boards, and paves the way for a fully automated SMT line.
Automatic OK/NG Sorting: Directly interfaces with your AOI system. Upon receiving a signal, it automatically routes boards to the correct OK buffer or NG buffer, ensuring perfect separation and traceability.
Smart & Reliable Control: Powered by an industrial PLC and managed via a user-friendly LED true-color touch screen. This ensures stable operation, easy recipe setup, and clear status visualization.
Jam-Proof Operation: Features a patented anti-jamming and fool-proof mechanical structure. This prevents board damage and costly line stoppages, even when handling thin, flexible, or irregular PCBs.
Seamless Line Integration: Designed for direct online docking. With standard I/O signal interfaces, it connects effortlessly to your AOI, conveyors, and downstream equipment, creating a continuous flow.
Robust Industrial Design: Built with heavy-duty materials and precision components for 24/7 reliability in demanding factory environments, ensuring long-term stability and low maintenance.
It Solves These Critical Production Challenges
Eliminates Manual Sorting: Removes the need for an operator to watch the AOI screen and physically remove NG boards, saving labor and reducing human error.
Prevents Mix-Ups: Ensures NG boards are never accidentally mixed with OK boards, protecting your quality and preventing field failures.
Increases Line Uptime (OEE): Provides a buffer zone. If the downstream process is briefly paused, OK boards can be temporarily stored, allowing the AOI and upstream processes to continue running.
Enables Traceability: By physically separating boards based on the AOI result, it simplifies tracking and logging of defect rates.
Protects PCBs: The gentle handling and jam-proof design prevent scratches, bumps, or damage to assembled boards during the critical post-inspection phase.
