III. Core Features

1. Sheet metal enclosed body with high-strength aluminum alloy integrated structure, good protection, dustproof and impact resistant, stable and durable operation.

2. Integrates NG/OK sorting, board material buffering, and straight-through operation modes, enhancing production line flexibility.

3. Equipped with a PLC intelligent control system, ensuring smooth board feeding and minimizing jamming, suitable for continuous mass production over extended periods.

4. Supports FIFO (First-In, First-Out) and LIFO (Last-In, First-Out) material handling logic, adapting to different production scheduling needs.

5. High-definition touchscreen operation with built-in automatic fault diagnosis, simple human-machine interaction, reducing manual maintenance costs.

6. Buffer lifting step distance can be freely set according to board thickness, compatible with various PCB thicknesses.

7. Hand-cranked screw width adjustment mechanism ensures precise adjustment and stable alignment without deviation.

8. Multi-channel audible and visual alarms + pop-up prompts provide real-time fault feedback, reducing downtime losses.

9. Standard SMEMA communication interface, compatible with upstream and downstream equipment such as AOI, SPI, reflow soldering, and pick-and-place machines for rapid network setup.

IV. Applicable Scenarios

SMT Placement Line: Placed after the pick-and-place machine and reflow soldering, it buffers PCB boards, balances the cycle time of each process, and solves problems such as board blockage and current interruption.

Semiconductor Manufacturing Process: Provides temporary buffering of wafer chips between photolithography, etching, and packaging processes, ensuring smooth process transitions.

Back-end Inspection Station: Equipped with SPI solder paste inspection and AOI optical inspection equipment, it receives inspection signals and automatically sorts and stores NG/OK boards, reducing manual sorting.
