OK/NG PCB Unloader for Automated Pass-Fail Sorting
Automatic end-of-line sorting that sends qualified boards and rejected boards into separate collection paths based on AOI or inspection signals. It removes manual sorting and keeps traceability cleaner at line exit.
| Sorting Logic | Automatic OK / NG separation |
| Input Signal | AOI / inspection pass-fail signal |
| PCB Size | 50 × 50 – 460 × 460 mm |
| Collection Lanes | 2 lanes / 2 magazines |
| Interface | SMEMA compatible |
Technical Specifications
| Sorting Method | Automatic OK / NG routing based on upstream signal |
| Input Signal | SMEMA / digital I/O from AOI or other inspection system |
| PCB Width Range | 50 – 460 mm |
| PCB Length Range | 50 – 460 mm |
| Collection Lanes | 2 lanes for OK and NG boards |
| Magazine / Collection Logic | Separate collection paths to avoid mixing qualified and defective boards |
| Interface Standard | SMEMA |
| Power Supply | 220V / 50Hz |
| Air Supply | 0.5 MPa |
Optional Configuration
| Signal Interface | Customized I/O wiring and signal logic for AOI, SPI, or customer-specific inspection systems |
| Lane / Magazine Setup | Different OK and NG collection arrangements based on defect-handling process |
| Alarm & Indication | Tower light, buzzer alarm, and full-magazine alert output |
| Line Direction | Left-to-right or right-to-left conveyor direction for integration with the full SMT line |
Who This Unloader Fits Best
Inline AOI Lines
Best for lines that already generate pass/fail signals and need automatic separation before finished-board collection.
Quality-Critical Production
Useful where mixing good and defective boards would create rework risk, traceability issues, or manual sorting waste.
Compared with Standard Unloaders
Choose this model when you need quality-based separation, not just simple end-of-line collection.
Compared with OK/NG Buffer
An OK/NG buffer sorts boards mid-line; this unloader performs the separation at the line end for final collection.
