PCB Buffer & Unloader for SMT assembly
The GW-ULF Series is an intelligent board sorting system installed at the end of SMT production lines, specifically designed to interface with AOI (Automated Optical Inspection) equipment. It automatically segregates inspected PCBs based on test results, streamlining quality control workflows.
Key Features:
- Smart Sorting Logic: Directly stores “OK” (pass) boards while holding “NG” (fail) boards for further determination or rework
- Round Belt Transport: Gentle handling ensures no damage to sensitive components during sorting
- Ultra-Low Power Consumption: Max 100 VA power requirement – highly energy-efficient
- Consistent Height Profile: Standard 1200mm height across all models for uniform line integration
- Extended Capacity Options: GW-ULFH250 offers enhanced magazine capacity (180kg) for high-volume operations requiring frequent changeovers
- Flexible Flow Direction: Optional left-to-right or right-to-left configuration adapts to various line layouts
