Traditional photoelectricity material separation device adopts visible light source and detector, obtains material to be selected at the spectral information of visible light wave range, has realized the sorting of a large amount of materials, such as agricultural product, marine product, plastics and ore etc.But under many circumstances,, the sorting objects for the treatment of that many materials are different has identical or close visible light characteristic, namely has same or analogous color and brightness, makes traditional photoelectricity material separation device be difficult to carry out sorting.
But under the irradiation of near infrared light, these colors are identical or similar, the material that material is different usually can have complicated near infrared spectrum structure, so the signal of near infrared detector there will be larger difference mostly.Then according to these difference, drive executing agency the material of unlike material separately.Therefore, with near infrared ray, as the material separation device of light source, for this type of material, embodied the unexistent powerful sorting capability of material separation device in the past.The production fields such as agricultural byproducts and industrial goods can be widely applied to, but heterochromatic material can not be effectively rejected.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of while can be with the compound material separation device of visible ray and/or infrared light identification material, as the useful of existing photoelectricity material separation device, supplement, effectively close the but material that infrared spectrum differs greatly of identification colors.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of visible ray and the compound screening installation of infrared material, comprise visible illumination system and Visible imaging system, visible illumination system comprises visible light source, Visible imaging system comprises gray scale camera or colored RGB camera, also comprises infrared illumination system and infrared imaging system; Infrared illumination system comprises infrared light supply; Infrared imaging system comprises infrared camera; Infrared light supply is in a side of visible light source, and infrared camera is arranged on a side of Visible Light Camera, before the camera lens of infrared camera, infrared fileter is housed.
As preferably, infrared light supply is infrared LED lamp.
As preferably, infrared light supply is Halogen lamp LED.
The beneficial effects of the utility model are:
Visible light source and infrared light supply are used as lighting source simultaneously, those heterochromatic materials so both can have been rejected, also can reject those at visible ray hypostome look same or similar, but because of the different material of material difference infrared spectrum, sorting function has obtained very large reinforcement, has expanded the sorting scope of material.
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 utility model visible ray and the compound screening installation embodiment of infrared material.
In figure, 1-vibra feeder, 2-hopper, 3-infrared light supply, 4-visible light source, 5-Visible Light Camera, 6-infrared camera, 7-nozzle, 8-substandard goods sub-material chamber, 9-certified products sub-material chamber.
The specific embodiment
A kind of visible near-infrared compound screening installation of Fig. 1, its illuminator is equipped with visible light source 4 and infrared light supply 3 simultaneously, and correspondingly, its imaging system is equipped with Visible Light Camera 5 and infrared camera 6 simultaneously.
Infrared light supply 3 is infrared LED lamp.In addition, infrared light supply can also be used Halogen lamp LED.
Because the present embodiment is to take visible ray system as main, therefore 4 visible light sources to be installed, and because of limited space, 2 infrared LED lamps can only to be installed as infrared light supply, infrared LED lamp is arranged on the side top of visible light source.
Visible Light Camera 5 is gray scale camera, also can use colored RGB camera.
Identical for the position of seeing with Visible Light Camera, infrared camera 6 is arranged on to a side of Visible Light Camera 5.
Because the infrared spectrum width of infrared LED usually only has tens nanometers, therefore energy comparison is concentrated, be applicable to processing two kinds of materials and in certain narrow infrared range of spectrum, there is the situation of notable difference, for example, certain two kinds of stone is obviously more much larger than its all band in the reflectivity difference of 1400nm left and right, therefore,, if select the infrared 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.
According to the selection of different light source and camera, the present embodiment can have following four kinds of structure patterns:
(1) collocation of visible LED, gray scale camera and infrared LED light source, infrared camera;
(2) collocation of visible LED, colored RGB camera and infrared LED light source, infrared camera;
(3) collocation of visible LED, gray scale camera and Halogen lamp LED, infrared camera;
(4) collocation of visible LED, colored RGB camera and Halogen lamp LED, infrared camera.
In above-mentioned pattern, for material that need only just can sorting by different gray scales, can preference pattern (1) or (3), be conducive to like this reduce construction cost.
The course of work:
Material, under the effect of vibra feeder 1, along down landing of hopper 2, has arrived in separatory vessel.Illuminator and imaging system are started working, and visible light source 4 is general with visible LED, infrared light supply 3 have Halogen lamp LED or two kinds of infrared LEDs optional, visible light source 4 and infrared light supply 3 are simultaneously luminous.Irradiation enters respectively in infrared camera 6 and Visible Light Camera 5 through reflection or transmission on material.Before infrared camera, be added with infrared fileter, only allow effective light transmission, the interference of other optical signals of filtering.After Visible Light Camera and infrared camera collect image, signal and data handling system are started working, according to the difference of the optical property of material, image information also has corresponding difference, system judges whether information meets default separation condition, if so, exports executive signal.Arrived the position of sub-material mouth, foreign body eliminating executive system (magnetic valve and nozzle 7) is started working, and non-defective unit falls into certified products sub-material chamber 9, and substandard products, by solenoid-driven nozzle 7, are blown in substandard goods sub-material chamber 8, thereby realize material sorting.Whole separation system operates realization by operating personnel by touch-screen by human-computer interaction interface.
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.
