A visual selection method and system for photovoltaic quartz sand

Abstract

The application discloses a kind of visual selection methods and systems of photovoltaic quartz sand, it is related to the field of visual selection, including single-granulation feed arrangement module, for by vibration feeding, guiding alignment mechanism, photovoltaic quartz sand material is continuously transported at uniform speed, material is converted into single-particle discrete, equidistant ordered stable arrangement state;Capture module is used for the multispectral image acquisition of the boundary coincidence of the transport path of single-particle arrangement photovoltaic quartz sand material, obtains the multi-dimensional optical imaging original data of material surface layer and subsurface;The application synchronously collects the multi-dimensional optical data of material surface layer and subsurface by multispectral imaging, effectively captures the subtle impurity information that traditional detection mode is difficult to find, can accurately identify Al, Fe, Ca, Ti, Na, K and other multiple trace impurity elements, makes efficient shunt collection of qualified and unqualified material, effectively improves the precision, efficiency and stability of photovoltaic quartz sand selection.
