Machines Integrated
  • Laser Scribing and Cleaving
    The Solar Cell Sorter incorporates the QSV module for laser scribing and cleaving, providing a streamlined solution for cleaving half-cut cells post Top Light Inspection (TLI). The module features a conveyor and theta aligner, ensuring a precise cut and subsequent realignment for optimum angles.
  • Cell Loader (QCL)
    The high-speed Cell Loader module is designed to efficiently unload solar cells from cassettes, minimizing breakage and maximizing production efficiency. The module includes a buffer station for seamless cassette changeovers, a flipper for changing cell orientation, and conveyors for smooth cell transport. The DM Reader ensures essential traceability for quality control.
  • Multi Tester (QTT)
    The QTT module features a main transportation line with a walking beam and output conveyor. Solar cells are positioned and aligned by the VA aligner, then tested at various stations including the Hot Spot Infrared Tester (HST), Laser Profiler (LP) for metal line profile measurement, Single Flash IV Tester (IVT), and Photoluminescence (PL) for microcrack and solder pads defects inspection.
  • Full-Fledged AOI Module (QSV)
    Our advanced AOI module is designed for precise surface cosmetic inspection, covering Shallow Angle Sunnyside Area Scan Inspection (SASAI), Rear Vision (RV), Dark Field Inspection (DFI), and Front Vision (FV). This includes 2D color area and line scan for front side inspection, line scan for rear side inspection, and 3D dark field line scan for embossed metallization defects on the rear side.
  • Link Module (QLM)
    The QLM module accurately places interleaf paper on the sunny side of solar cells and separates them into two sorters. A 4-head pick-and-place robot handles incoming cells, with an alarm indicating when interleaf paper needs refilling. The interleaf bin is automatically indexed out for operator refilling.
  • First & Second Sorter (QFS & QSS)
    The delta robot swiftly picks up cells and places them in the correct bin as they reach the pickup position. A user-friendly touch screen interface facilitates bin selection for indexing out, ensuring efficient and organized sorting.
