Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the infrared material separation device embodiment of the utility model.
Fig. 2 is that two kinds of stones are at the reflectivity spectral of near infrared band.
In Fig. 1,1-vibra feeder, 2-hopper, 3-infrared camera, 4-infrared light supply, 5-nozzle, 6-substandard goods sub-material chamber, 7-certified products sub-material chamber.
The specific embodiment
An infrared material separation device, its illuminating lamp and camera are comprised of infrared light supply 4 and infrared camera 3 respectively.
Infrared light supply adopts infrared LED or Halogen lamp LED.
Infrared material separation device as shown in Figure 1, material is under the effect of vibra feeder 1, along down landing of hopper 2.Arrived in separatory vessel, illuminator and imaging system are started working, infrared light supply 4 is infrared LED(or Halogen lamp LEDs), the irradiation sending is on material, through reflection or transmission, by infrared camera 3, received, infrared camera 3 is added with infrared fileter above, only allows effective light transmission, the interference of other optical signals of filtering.After infrared camera 3 collects image, signal and data handling system are started working, and according to the difference of the optical property of material, image information also has corresponding difference, and system judges whether information meets default separation condition, if so, exports executive signal.The position of having arrived sub-material mouth, solenoid-driven nozzle 5 is started working, and non-defective unit directly falls into certified products sub-material chamber 7, and substandard products are blown in substandard goods sub-material chamber 6 by nozzle 5, thereby realize material sorting.
Whole separation system operates realization by operating personnel by touch-screen by human-computer interaction interface.
The present embodiment utilizes near infrared light as light source, can select infrared LED lamp or Halogen lamp LED, and wherein LED lamp monochromaticjty is better, light stability, the feature such as brightness is adjustable, long service life.And the spectral region of Halogen lamp LED is very wide, and product is ripe, and alternative leeway is large, and price is low.
The present embodiment has been used infrared camera, and nearly infrared signal converts picture signal to.
According to above-mentioned two kinds of different light sources, select, the present embodiment has two kinds of structure patterns, and a kind of is the collocation that adopts LED light source and infrared camera, and another kind is to adopt Halogen lamp LED and infrared camera collocation.
For the first situation, because the spectral width of LED usually only has tens nanometers, therefore energy comparison is concentrated, be applicable to processing two kinds of materials and in certain little spectral region, there is the situation of notable difference, as shown in Figure 2, two kinds of stones are obviously more much larger than its all band in the reflectivity difference of 1400nm left and right, therefore, if select the LED of 1400nm wave band left and right, can separate preferably these two kinds of materials.The advantages such as under this pattern, energy of light source can be fully utilized, and has therefore brought energy consumption low, and heat is little, in addition, also have the distinctive life-span of LED long, and brightness is adjustable, brightness stability etc. advantage.But this pattern is also restricted, the wavelength that is mainly LED product is not to have at whole infrared band, and existing product mainly concentrates on some separated wave bands.This has just caused the sorting of many materials cannot find the light source matching.Therefore, we have designed the pattern that adopts Halogen lamp LED simultaneously.
Halogen lamp LED is because its spectrum can easily cover infrared very wide scope, therefore, as long as the infrared signature peak of material falls within the scope of this, Halogen lamp LED is exactly effective lighting source, in order to improve signal to noise ratio, reduces the impact of the outer light energy of characteristic peak, at this moment, before the camera lens of infrared camera, infrared fileter is housed, the efficient light (characteristic peak of corresponding spectrum) that only allowing needs sees through, and has avoided the interference of other light to signal; The installation of optical filter is the collar of having used convenient disassembly, can change different types of optical filter; Infrared camera is used the detectors such as InGaAs, PbS.The problems such as adopt the weak point of Halogen lamp LED to be that the Energy distribution of light is wide, useful usually only has 1/10th even still less, in order to obtain enough strong signal, needs higher power, causes caloric value high, and efficiency is low.
When material complicated, can adopt a plurality of infrared cameras, each camera is joined the form of different band pass filter, detects a plurality of different characteristic peak of material, and then by the combination of these characteristic peaks, realizes the detection of complex materials.
No matter be to adopt the mode of operation of LED or the mode of operation of Halogen lamp LED, can by electric current, regulate the brightness of background and front light, easy to use, precise control.Also can adopt other mode to adjust background light intensity, for example, adopt the signal of the background board reflecting background lamp of rotation, by different reflection angles, adjust catoptrical intensity, realize thus the adjusting of camera background signal intensity.
Above-described the utility model embodiment, does not form the restriction to the utility model protection domain.Any modification of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present utility model.
