Four Principles of Light Source Selection for Plastic Color Sorter
The optics of plastic color sorter consists of feeding system, optical system, sorting system and electronic control system, for example, the five basic systems of plastic color sorter mentioned above. Each system is composed of many components, and the light source is an indispensable part of the optical system. It is related to the ability to distinguish qualified and defective products, and affects the effective removal of different colors and particles in the plastic color sorter.
1. The spectral energy distribution characteristics of the light source shall meet the requirements of the measured object and be compatible with the spectral response of the receiver. If necessary, add filters to remove unwanted radiation. Through proper matching, better results can be obtained with small energy. This is not only a problem of energy conservation, but also an unnecessary interference caused by excess energy.
2. Photometric characteristics. The polar coordinate distribution of light source brightness and light intensity shall also be selected according to the use requirements and the performance of the receiver. Generally, stronger light will help improve the signal-to-noise ratio and the processing of electronic control systems.
3. Shape, dimensions and structural dimensions of the light-emitting surface. The proper shape of the light-emitting surface can make full use of its light energy to make the measured object glow uniformly. The size of the light-emitting surface and the structure size of the light source will affect the structure size of the machine, which can be selected according to the overall layout of the machine, and can be customized to the manufacturer as required.
4. Other factors: whether the power supply system of the light source is complex, whether cooling is required during use, service life, convenience of replacement and economy should be taken into account.
