SMT PCB Reject Conveyor for Automated Production Lines

The SMT PCB reject conveyor is designed to separate and temporarily store defective PCBs in automated SMT production lines. It is typically installed behind AOI or SPI inspection equipment. The conveyor distinguishes NG and OK boards through its dual-line identification system.

When an NG board arrives, the lifting mechanism raises it into the storage position. The unit can store up to 10 rejected PCBs. Meanwhile, qualified OK boards pass directly to the next machine. This process helps operators manage defective boards without interrupting the normal transfer of accepted PCBs.

Key Features of the SMT PCB Reject Conveyor

1. Automatic NG Board Storage

The conveyor uses a lifting mechanism to store rejected PCBs. It can hold up to 10 NG boards, providing temporary storage after inspection. Operators can retrieve defective boards for further checking and rework.

2. Direct Transfer for OK Boards

Qualified PCBs pass through the conveyor and move directly to the downstream machine. This design supports continuous board transfer and reduces unnecessary handling.

3. Dual-Line NG/OK Identification

The dual-line identification system distinguishes NG and OK boards. It helps operators identify rejected boards and manage PCB flow after AOI or SPI inspection.

4. Stable PLC Control System

A microcomputer PLC control system manages the conveyor's operating process. The system supports stable and reliable equipment operation.

5. Touchscreen Operation and Fault Diagnosis

The touchscreen provides a convenient human-machine interface. Operators can monitor equipment status and interact with the control system. The automatic fault diagnosis function helps identify equipment problems.

6. Multiple Alarm and Prompt Functions

The conveyor features sound and light alarms, together with touchscreen prompts. These functions notify operators when attention or intervention is required.

7. Stepper Motor Transmission

A stepper motor drives the conveyor transmission system. This configuration supports controlled PCB movement during inspection and board handling.

8. Durable Industrial Structure

The equipment uses a sheet-metal exterior and an aluminum-profile frame. Its surface receives spray treatment, with a wavy white finish for a clean industrial appearance.

Applications

The SMT PCB reject conveyor is suitable for automated SMT production lines, especially for installation behind:

• AOI inspection machines: Separates rejected boards after automated optical inspection.

• SPI inspection machines: Supports NG board storage and OK board transfer after solder paste inspection.

• SMT PCB handling systems: Helps manage PCB flow between inspection and downstream processes.
