How It Works
The PCB Cooling Buffer Conveyor operates with the coordination of PLC system, air cooling module and layered lifting buffer mechanism.
- Cooling Principle: Silent upper-lower convection fans build circulating air channels to continuously dissipate heat from PCBs after reflow, rapidly cooling hot boards down to safe temperature for inspection, avoiding component damage and false test results caused by high temperature.
- Buffering Principle: Lifting storage compartments hold PCBs in layers to match the tact time between reflow oven and downstream equipment like AOI and ICT. It automatically stores PCBs when downstream machines run slowly or stop for maintenance, and feeds boards sequentially when downstream equipment is idle to balance process difference and prevent line blockage.
- Conveying Control Principle: Electric adjustable conveyor rails cooperate with automatic transfer mechanism, linked with upstream and downstream machines via SMEMA signals for fully automatic board in/out, and audio-visual alarms will be activated under abnormal conditions.
Application Process
- Hot PCBs discharged from reflow oven are conveyed into the buffer machine through connecting rails.
- Upper and lower convection fans start to force air cooling, rapidly lowering PCB temperature to the standard inspection range.
- Lifting mechanism stores cooled PCBs in separate layers and automatically counts buffered boards.
- When downstream AOI / ICT equipment is ready, the machine feeds PCBs layer by layer to the next process.
- If downstream machines stop for maintenance, the Large Capacity PCB Buffer Machine keeps storing boards to avoid blockage and shutdown of the upstream reflow oven.
- The whole process is automatically controlled by PLC. Audio and visual alarms will trigger to alert operators for faults such as no board, full buffer or board jamming.
