Abstract
A light path structure of detection analyzer is composed of a light source plate, a lens seat, a detection disk and a photocell detection assembly. It is characterized in that on the light source plate are mounted eight LED lamps arranged in arrays; and stable light source with uniform wavelength and energy is generated by the LED lamps, converged through the lens, absorbed by the detection liquid of the detection disk, and detected by the photocell detection assembly to realize photoelectric signal conversion. Corresponding to the movement of the walking plate of the detection disk, the photocell detection assembly can detect eight-hole detection liquids for twelve times at twelve position signals, namely detecting ninety-six detection liquids at one time, so as to realize mass detection. The invention has simple structure, low cost, simple and convenient wavelength change, and high scalability.

Technical field
The utility model relates to check and analysis instrument light path system, specifically is a kind of light channel structure of check and analysis appearance.
Background technology
Present various food security series detector one-time detection quantity basically is merely several, and detection speed is slow, and automaticity is low; Be not suitable for mass detection; Its main cause is that its light channel structure only has 1 or 2 passages, aspect light source, does not have the semiconductor light emitting source of High Accuracy Control wavelength, and does not have light source eyeglass seat secondary condensation; Generally do not have array way and expand fast, it has limited the quantity of disposable detection.And along with food security improves in the requirement aspect the rapid batch screening, this just needs a kind of check and analysis appearance of new type light line structure to realize.
Summary of the invention
The purpose of the utility model provides a kind of light channel structure of check and analysis appearance, and the detection liquid that it can carry out a plurality of passages simultaneously detects, and has satisfied the needs of batch detection and fast detecting.
The technical scheme that the utility model is taked is: a kind of light channel structure of check and analysis appearance; Comprise that light source board, eyeglass seat, detection dish and photoelectric cell detection components constitute, it is characterized in that being equipped with on the said light source board eight LED lamps, produce the stabilized light source of wavelength and energy coincidence by the LED lamp by arrayed; See through eyeglass seat optically focused; Detection liquid through the detection dish absorbs, and is detected by the photoelectric cell detection components again, realizes the photosignal conversion.
The specific wavelength of said LED lamp is the light of penetrating between 445nm～455nm.
Said light source board and eyeglass seat are fastened together.
Said photoelectric cell detection components once detects the detection liquid of eight passages simultaneously.
The characteristics and the beneficial effect of the utility model are:
1) adopts lower powered eight LED lamps that can produce the specific wavelength core; Form light channel structure with eyeglass seat, detection dish and photoelectric cell detection components; The limp of corresponding detection dish is moved, and the photoelectric cell detection components can detect the detection liquid in eight holes of ten secondaries at 12 position signalling places; Be 96 liquid to be detected of disposable detection, realized mass detection.Its light channel structure is simple, and cost is low, and the wavelength change is simple, convenient, and expansion is strong.
2) scope of application is extensive.The utility model can be widely used in the detecting instrument of various directed safety detection classes, comprising: food safety detection appearance, pesticide residue rapid detector; The detection of veterinary drugs in food appearance, fowl poultry safety rapid diagnosis analysis appearance, animal epidemic rapid diagnosis analysis appearance; The antibiotic residue tacheometer, the residual quick detector of biotoxin, aquatic products drug residue detection instrument; The residual quick detector of zoohormone; The comprehensive quick diagnosis appearance of bee product safety, the comprehensive tacheometer of meat safety, the comprehensive fast detecting appearance of dairy products safety etc.

Label is represented respectively among the figure: 1 light source board, and 2-eyeglass seat, the 3-LED lamp, 4-detection dish, 5-photoelectric cell detection components, 6-detects liquid.
Embodiment
Like Fig. 1, shown in Figure 2; The check and analysis appearance light channel structure of the utility model comprises that mainly light source board 1, eyeglass seat 2, detection dish 4 and photoelectric cell detection components 5 constitute, on light source board 1, be equipped with eight by arrayed, can produce the LED lamp 3 of specific wavelength core, LED lamp 3 provides fixed voltage by mu balanced circuit; Make LED lamp 3 produce the stabilized light source of wavelength and energy coincidence; The LED lamp source sees through eyeglass seat 2 optically focused, through detection liquid 6 absorptions of detection dish 4, is once detected the detection liquid of eight passages more simultaneously by photoelectric cell detection components 5; The realization photosignal is changed, and obtains quantitative, the qualitative results such as concentration of each test item after treatment.
It is the light of penetrating between 445nm～455nm that present embodiment adopts the specific wavelength of LED lamp 3.
Fig. 3 illustrates the utility model light source assembly structure, and it is made up of light source board 1 and eyeglass seat 2, and eight LED lamps 3 are pressed the arrayed device on light source board 1; In the eyeglass seat 2 plano-convex lens is installed; The plano-convex lens direction makes progress, and light source board 1 is fastened together with eyeglass seat 2, has guaranteed accurate positioning.
In the practical application: when the eight bundle light time that 4 motions of detection dish produce through LED lamp 3; Eight bundle light simultaneously eight of the same row of irradiating and detecting dishes 4 detect liquid 6, and the detection and location device detects emission light, eyeglass seat 2 lens, detect liquid 6 is on the same axis, and this moment, feedback information was to center dies; Center dies is sent instruction lets photoelectric cell detection components 5 receive through detecting the light signal after liquid 6 absorbs; The inductive energy size is carried out opto-electronic conversion, realizes the detection to the survey material concentration.During detection, 4 limp campaigns completion is coiled in detection, and photoelectric cell detection components 5 can detect the detection liquid in eight holes of ten secondaries at 12 position signalling places, and 96 liquid to be detected of promptly disposable detection have been realized mass detection.
With eight fixing LED lamps 3 of light source board 1,, can directly carry out conversion in the utility model, promptly be transformed to the LED lamp that another kind can produce specific wavelength on request and get final product eight LED lamps 3 in the light time that detectable requires to adopt other a kind of wavelength.
