XS610 0.6M NG‑OK Buffer
XS610 0.6M NG‑OK Buffer is SMT NG‑OK buffer machine. It automatically sorts and stores OK & NG PCBs, balances line tact time. Compact frame supports easy line connection to boost SMT production efficiency.
- Automatically distinguish and temporarily‑store OK qualified PCBs and NG defective PCBs.
- Coordinate speed difference between upstream and downstream equipment, balance process tact time.
- Absorb line fluctuation, prevent PCB stacking & board blocking to ensure continuous production.
- Connect with AOI, SPI and other inspection machines for SMT in‑line production.
- Automatically release buffered PCBs according to line status without manual operation.

Why choose this product?
Why choose the XS610 0.6M Fully‑Automatic PCB Buffer? The XS610 0.6M Fully‑Automatic PCB Buffer is a practical SMT peripheral equipment. Featuring compact structure and small footprint, the XS610 0.6M Fully‑Automatic PCB Buffer realizes sorting and buffering for OK/NG PCBs. It comes with adjustable speed for convenient production line docking. The reinforced frame ensures stable operation of the XS610 0.6M Fully‑Automatic PCB Buffer, which can effectively reduce board jamming and cut production downtime to optimize SMT line throughput.

How It Works
- Receive OK / NG inspection signal from upstream AOI / SPI equipment.
- Sensor detects incoming PCB and reads board judgment result.
- According to signals, store OK boards and NG boards into corresponding buffer slots separately.
- XS610 PCB Buffer performs stacked PCB temporary storage to absorb SMT line tact‑time fluctuation.
- Automatically output PCBs to downstream machine when rear‑end is idle.
- Mechanism resets after discharging and waits for next incoming PCB.
Application Process
- Power‑on the XS610 PCB Buffer, configure parameters, and connect upstream & downstream inspection machines.
- Receive PCB OK / NG judgment signal transmitted from AOI / SPI.
- Upstream feeds PCB into XS610 0.6M NG‑OK Buffer, sensor detects PCB arrival.
- Send PCB to corresponding slot for stacked temporary storage based on OK/NG signal.
- Automatically release buffered PCBs for downstream transfer when downstream is idle.
- Upon operation completion, XS610 PCB Buffer resets, awaits next PCB feed and keeps cyclic working.

Requirements
- Use rated power supply; supply voltage must satisfy XS610 SMT NG‑OK Buffer specifications.
- Install on flat and firm ground, keep environment dry and low‑dust.
- Size and weight of processed PCBs shall be within allowable range of XS610 0.6M NG‑OK Buffer.
- Complete correct wiring for OK‑NG signal communication with upstream AOI/SPI.
- Adjust machine height to align transport height of upstream and downstream SMT equipment.
- Overload operation prohibited; inspect transmission mechanism regularly for maintenance.
What It Is Used For
XS610 SMT NG‑OK Buffer is applied to various PCBA boards on SMT lines. It automatically sorts and buffers OK qualified and NG defective boards from AOI/SPI, supporting PCB substrates for consumer electronics, industrial control and home appliances.
