The original grain color separator also applies the visual inspection system
Color separator by using optical equipment according to the material color is different color particles in the difference of granular material points high-tech photoelectric integration of the mechanical equipment automatically. Taihe working principle of the photoelectric color separator is selected objects from the top of the machine into the hopper into the machine, through the vibration of the vibration device materials uniform will be assigned to the object selected materials along the material trough manger speed down to reach the separation chamber. The separation chamber of CCD sensor to obtain the material color and shape information. The CCD camera sends the information to the FPGA + DSP architecture processor, processor through efficient image processing algorithm to distinguish between normal material defects in the material, and then by controlling the high frequency electromagnetic valve gear will be defective material into the cavity by waste material, the normal finished materials continue to fall into the hopper of cavity, so as to achieve the aim of eliminating defective material.
Today humans have intelligent visual separation technology and its principle is similar to the human eye visual judgment, so called intelligent visual separation technology. When choosing lighting source generally measured normal material and defective material according to the spectral curve features (the reflected light and transmitted light, excitation fluorescence, etc.) or a similar combination design of normal material and defective material detection sorting spectral lines to strive to maximize contrast. Thus more thoroughly the material defects in sorting out. Intelligent color separator is widely used more optimization algorithm will provide customers with better color effect, in order to meet the people are more stringent requirements for products, win more and more high-end market for processing enterprises.
