Solar wafer counter

The utility model provides a solar wafer counter, belonging to the technical field of wafer counting detection and relating to an instrument for fast and accurate counting of wafers and on-line detection of marginal physical defects in the production process of solar wafers. The solar counter consists of a monochromatic light source, a data processing center, a display screen, a data transmission module, a data output module, a dual cameral, and the like. The solar counter specifically adopts a dual monochromatic camera distinguishing technology, conducts gray analysis to wafers, and samples gray peaks and troughs to reach the purpose of counting. The solar counter can replace artificial counting and conventional estimation algorithm, can help solar cell production units to effectively count production, shipment quantity and quality control of solar cells, therefore increasing production efficiency and controllability.
