Quartz sand color sorter is an intelligent device that uses optical
recognition technology to automatically identify and remove impurities in quartz
sand. One of its core components is the light source system. The stability and
brightness of the light source are directly related to the color selection
accuracy and sorting effect, so light source attenuation is one of the key
factors affecting equipment performance.
Firstly, the color sorter irradiates quartz sand particles with light of a
specific wavelength, and the reflected light signal is captured and analyzed by
a camera system. If the light source attenuates, the illumination intensity
decreases, the image contrast weakens, resulting in abnormal camera recognition
and reduced color selection accuracy. Manifested as an increase in impurity
removal or incorrect removal rate of good products.
Secondly, light source attenuation can cause system calibration deviation.
When setting up the color sorter for the first time, parameters such as
background light and recognition threshold will be configured based on the
intensity of the light source. Once the light source ages, the original
parameters will no longer be suitable for the current actual lighting
environment, which will affect the accuracy of software judgment and lead to
fluctuations in sorting results.
Thirdly, some color sorting machines use LED, halogen lamps, or cold light
sources, which have limited light source lifespan. After long-term operation,
the brightness of the light source decreases or the color temperature drifts,
especially in multi-channel color selection. Different channel light sources
have inconsistent attenuation, which can lead to color difference judgment
errors and affect the uniformity and consistency of color selection.
In addition, light source attenuation may also lead to a decrease in
equipment operating efficiency. To compensate for the insufficient intensity of
the light source, operators may be forced to increase sensitivity or lower the
rejection threshold, thereby affecting the overall yield and recovery rate,
increasing the loss of good products, and reducing economic benefits.
Therefore, it is crucial to regularly inspect and replace the light source of
the color sorter. It is recommended to regularly replace the light source
according to the service life provided by the equipment manufacturer to maintain
the stability of the recognition system. For high-frequency quartz sand
production lines, a light source attenuation monitoring function should be
installed to ensure long-term stable and reliable color selection effects.
In summary, the attenuation of the light source of the quartz sand color
sorter will significantly affect the recognition accuracy, color selection
efficiency, and product quality. Production enterprises need to attach great
importance to the maintenance and management of the light source to ensure the
long-term efficient operation of the equipment.
