Description
Technical field
The present invention relates to a kind of colloidal gold test paper card analyser, particularly a kind of detection darkroom of colloidal gold test paper card analyser.
Background technology
At present, chemical pollutant ubiquity in food and environment, traditional food chemical pollutant adopts colloid gold test paper Site Detection, its testing result is mainly by range estimation, cannot data analysis, greatly, testing result lacks objectivity for deviation ratio and human factor variation, so be badly in need of the analytical equipment working out antigen concentration on energy accurate quantitative analysis Test paper card.
In order to strengthen sensitivity and the reliability of analytical equipment, it has higher requirement to image acquisition light path system.
Summary of the invention
The invention provides a kind of detection darkroom of colloidal gold test paper card analyser, comprise closed lucifuge box, illuminating lamp plate, camera lens, described illuminating lamp plate has two, be individually fixed in the inner both sides near bottom of lucifuge box, on illuminating lamp plate top, lucifuge plate is set, lucifuge plate middle part is provided with optical filter, for converging and diverging light, described camera lens is connected with lucifuge box front end is airtight, for gathering the image information in colloidal gold test paper card colour developing district, one sidewall of described lucifuge box is provided with sidewall opening, for inserting colloidal gold test paper card.
Described illuminating lamp plate, adjustable both sides being fixed on the inner close bottom of lucifuge box, be connected with lamp plate knob by lamp plate web member, lamp plate knob inside has angle and the luminous intensity of variable resistor adjustable illuminating lamp plate.
Described detection darkroom also comprises level crossing, and described level crossing is arranged on plane mirror holder and is fixed on inside, lucifuge box front end, each one of camera lens both sides, and plane mirror holder is connected with level crossing rotary knob, and it is outside that level crossing rotary knob is arranged at lucifuge box back.
Described lucifuge box is made up of black PVC or PE material.
Described level crossing and lucifuge plate are 45° angle.
Described illuminating lamp plate is that the LED of the emerald green coloured light of 525nm forms by 6 wavelength.
The detection darkroom of colloidal gold test paper card analyser of the present invention, stray light can be filtered, and strengthen the intensity of light source, be conducive to camera photosensitive unit and obtain effective light signal, illuminating lamp plate is set to angle with analyser and intensity of illumination is adjustable, and add the level crossing of adjustable-angle, the stability of intensity of illumination and symmetry all can be made to strengthen.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in more detail, but be not used for limiting the present invention.
The detection darkroom of colloidal gold test paper card analyser, comprise closed lucifuge box 1, the illuminating lamp plate 5 of light emitting diode composition, camera lens 2, described illuminating lamp plate 5 has two, be individually fixed in the inner both sides near bottom of lucifuge box 1, on illuminating lamp plate 5 top, lucifuge plate 12 is set, lucifuge plate middle part is provided with optical filter 9, for filtering veiling glare, described camera lens 2 is connected with lucifuge box 1 front end is airtight, to develop the color the image information in district for gathering colloidal gold test paper card 10, one sidewall of described lucifuge box 1 is provided with sidewall opening 11, for inserting colloidal gold test paper card 10.
Described closed lucifuge box 1 is made up of black PVC or PE material, form the environment of a relative closure, extraneous light can not enter, effectively to amass wealth by heavy taxation internal light source, in black, wall energy effectively absorbs target area unwanted reflected light line simultaneously, avoid light multiple reflections to enter optically focused camera lens, make the target area usable reflection light of colloidal gold test paper card evenly more stable.
Described illuminating lamp plate 5, can be arranged to adjustable both sides being fixed on the inner close bottom of lucifuge box 1, be connected with lamp plate knob 7 by lamp plate web member 6, lamp plate knob 7 inside has angle and the luminous intensity of variable resistor adjustable illuminating lamp plate 5.
Illuminating lamp plate is that the LED of the emerald green coloured light of 525nm forms by 6 wavelength, by the LED illumination lamp of warm white, positive white, yellow, yellow green, emerald green different colours, testing standard card gradient data result, find when different colours illumination, the gray scale of standard card reads value magnitude of size, and gradient disparities is obvious, wherein emerald green illumination test, gap between area color and chromogenic line is the most obvious, the standard card data gradient span of the different colours depth is large, therefore selects emerald green coloured light as lighting source.
The detection darkroom of colloidal gold test paper card analyser can also comprise level crossing 3, described level crossing 3 is arranged on plane mirror holder 4 and is fixed on inside, lucifuge box 1 front end, each one of camera lens 2 both sides, plane mirror holder 4 is connected with level crossing rotary knob 8, it is outside that level crossing rotary knob 8 is arranged at lucifuge box 1 back, the light that level crossing can collect reflectance-transmittance optical filter is set, plays the effect strengthening light, be more conducive to camera photosensitive unit and obtain effective light signal.Verified by many experiments, show that the effect of the enhancing light efficiency played is best when both sides level crossing 5 is 45 ° with lucifuge plate 12.
