AI quality inspection system for fast and accurate detection of defects occurring in solar cell and module manufacturing processes

AOI Inspector

Overview
A solar AOI (Automated Optical Inspection) Inspector is an equipment that automatically inspects wire spacing and dimensional accuracy of solar cells • modules, as well as various appearance and shape defects.
It is a part where it is possible to detect even unstructured defects through self-made AI SW by TWIM and has been applied toward production processes of solar module in North America.
Introduction Effects
  • Quality improvement and prevention of defect leakage
  • Preventing downstream processing and reduction of disposal cost through defect detection
  • Possible to do final quality inspection at the lamination pre- and post-process stages and FQC stage, including evaluation of cell and string alignment and spacing, as well as detection of foreign matter, scratches, and glass breakage
  • Prevention of factors causing power generation loss in advance (improvement of electricity output)
Application Examples
  • Company H: Adaption of solar module to factories
Application Fields
  • Applicable to next-generation solar cell technogy areas and various panel types including Solar Cell · Solar Module · BIPV · TOPCon · HJT · Perovskite · EOL Inspection etc.
