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.
