Do you still need operators to manually separate NG and OK PCBs after AOI inspection?

In modern electronics manufacturing, production efficiency and quality control have become increasingly important. After PCB inspection by AOI machines, many factories still rely on operators to manually identify, collect, and separate defective and qualified boards.

This traditional method not only increases labor costs but also creates risks of incorrect sorting, missed handling, and reduced production efficiency.

How can manufacturers automatically separate NG and OK PCBs while keeping the SMT production line running smoothly?

The answer is the 825NGOK Dual Lane Automatic PCB NG OK Sorting Unloader, developed by Shenzhen Shengdian Electronic Equipment Co., Ltd.

This intelligent PCB handling solution is designed to connect with AOI inspection systems and automatically sort PCBs according to inspection results, helping electronics manufacturers achieve higher efficiency, lower labor dependence, and more stable production.

Automatic NG OK PCB Sorting After AOI Inspection

The 825NGOK automatic PCB unloader can directly connect with AOI inspection equipment through SMEMA communication signals.

After AOI inspection, the system automatically receives the inspection result and identifies whether the PCB is a qualified board (OK) or defective board (NG).

When an OK signal is received, the PCB is automatically transferred into the OK magazine.

When an NG signal is received, the PCB is automatically transferred into the NG magazine.

This process eliminates manual sorting operations and ensures accurate classification of PCBs during production.

With automatic NG and OK separation, manufacturers can improve production consistency while reducing human operation errors.

Dual Lane Design for Higher SMT Production Efficiency

Unlike traditional single-lane PCB unloaders, the 825NGOK features a dual-lane structure.

Each lane can independently receive AOI signals and complete PCB identification, transfer, and sorting operations.

The dual-lane design allows the equipment to better match high-speed SMT production requirements, helping factories increase throughput and improve overall line efficiency.

For EMS manufacturers and PCB assembly factories, stable PCB handling after inspection is an important part of maintaining continuous production.

Smart Control System with Easy Operation

The 825NGOK PCB sorting machine is equipped with a reliable PLC control system and touchscreen operation interface.

Operators can easily monitor machine status through the display, making daily operation more convenient and efficient.

The equipment also provides automatic fault diagnosis and alarm functions, helping operators quickly identify abnormal conditions and reduce machine downtime.

Simple operation and easy maintenance make the equipment suitable for long-term industrial production environments.

Flexible Design for Different PCB Production Requirements

Different PCB products may have different thicknesses, sizes, and component heights.

The 825NGOK supports adjustable magazine lifting distance according to PCB thickness and component height requirements, allowing the equipment to adapt to various production applications.

The push mechanism uses a stepper motor system. The pushing speed, force, and travel distance can be adjusted through the touchscreen, helping protect PCBs during transportation.

Reliable Structure for Long-Term SMT Operation

For continuous factory production, equipment stability is essential.

The 825NGOK automatic PCB unloader adopts a strong mechanical structure combined with industrial-grade components to ensure reliable operation.

The conveyor system uses anti-static belts and seamless guide rails to provide smooth PCB transportation and reduce the risk of board jamming.

The lifting system uses a high-precision servo motor and precision ball screw structure, ensuring stable lifting movement and accurate positioning.
