Buffer Conveyor

Also known as an NG Buffer or NG/OK Sorting Buffer, this equipment is positioned after single-rail inspection machines. It manages board flow by buffering NG (No-Good) boards and passing OK boards straight through, or serves as a general buffer behind high-speed production lines. Custom sizes are available to match various application scenarios, and the machine is primarily composed of a transmission guide rail, a lifting buffer unit, and electrical controls.

Machine Features & Technical Advantages

Precision Guide Rails & Synchronous Belt: The conveyor guide rails are precision-machined, driven by high-strength synchronous belts and stepper motors, ensuring high operational stability and accurate positioning.
Automated Lifting Buffer Unit: The lifting buffer mechanism features precision-machined parts powered by a stepper motor with automated control, making operation and debugging easy.
Three Versatile Operating Modes: Supports three operational modes to suit different production needs: NG Buffer Mode, Standard Buffer Mode, and Pass-Through (Direct) Mode.
Modular & Customizable Design: Machine dimensions and specifications can be tailored to meet your specific production line layout and buffering requirements.
