Embodiment

Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the utility model do, but embodiment of the present utility model is not limited thereto.

Shown in Fig. 1～4, color sensor 1 is welded on the central authorities of circuit board 5, and links to each other with circuit in the circuit board 5, is used to receive color signal.Optical path component 4 also is fixed on the face of circuit board 5 by screw, is used for the light that tested sample reflects is converged and filters the light of part wavelength, only keeps to detect the required wavelength coverage of sample.

Described optical path component 4 is made of shell 9, convex lens 10, spacer ring 11, optical filter 12 and trim ring 13.Shell 9 is for having the right cylinder of through hole, and convex lens 10, spacer ring 11, optical filter 12 and trim ring 13 all are placed on the inside of shell 9.Wherein, convex lens 10 are placed on the bottom of shell 9, and keep certain height with the end face of shell 9 bottoms.Spacer ring 11 is placed on the surface of convex lens 10, and optical filter 11 then is placed on the surface of this spacer ring 11, so that optical filter 11 does not directly contact with convex lens 10.Trim ring 13 is placed on the outermost end of shell 9, i.e. the top of shell 9.Because trim ring 13 self is provided with external thread, and the inwall of shell 9 is provided with internal thread, thus trim ring 13 by with shell 9 on internal thread mesh, thereby make convex lens 10, spacer ring 11, optical filter 12 linking together and can not be scattered tightly.

Color sensor 1 is arranged on the inside of shell 9, so that the necessary wavelength that the good receiving light path assembly 4 of color sensor 1 energy is reflected.Because convex lens 10 maintain certain height with the bottom end face of shell 9, so color sensor 1 can not contact with convex lens 10.

Circuit board 5 also divides other to be fixed with 6, two white LED light sources 2 of a base in the both sides of optical path component 4 and is separately fixed at above two bases 6, and link to each other, so that can provide electric energy for white LED light source 2 with circuit board 5.In order to guarantee to detect effect, each base 6 will be located on the same line with the white LED light source 2 that is fixed on this base, and each base 6 and the line that is fixed on the white LED light source 2 on this base, promptly the plane of the center line of base 6 and circuit board 5 is also in an angle; Simultaneously described two bases 6 also are located on the same line with optical path component 4.Because this angle is with the distance of white LED light source 2 with color sensor 1, and color sensor 1 is different with the distance of tested sample, so the span of this angle is 0 °～90 °.

In order to provide electric energy, on circuit board 5, also be provided with power input mouth 7, so that link to each other with external power source by this power input mouth 7 for described color sensor device 1 and white LED light source 2.Simultaneously, on circuit board 5, also be provided with control port 8, so that the signal that is collected is uploaded to system by this control port 8.

As shown in Figure 5, when using the utility model and detect, only tested sample 3 need be placed on optical path component 4 under get final product.Because color sensor 1 is the inside that is fixed on optical path component 4, thus tested sample 3 just be placed on color sensor 1 under, be convenient to color sensor 1 and receive the signal that tested sample reflects.The collection face of optical path component 4 (being the end face of optical path component 4) parallels with the tested surface of tested sample 3, and keeps certain height.This can make suitable adjustment highly according to specific circumstances, to guarantee collection effect.

When detecting, tested sample 3 arrives after the test position, and two White LED light sources 2 are switched on, and send the very strong cool white light of brightness.When cool white light is radiated on the test sample book 3, tested sample 3 reflects into light into light path assembly 4, through optical path component 4 light that reflects is converged and filters and be sent to color sensor 1 behind the light of part wavelength and carry out signals collecting, and the signal that is collected is uploaded to system by color sensor 1, calculate for systematic analysis.

As mentioned above, just can realize the utility model preferably.
