The specific embodiment
The present invention is a kind of line illuminator that is applied to the tunable optical on the checkout equipment; The particularly a kind of means that can utilize light source to regulate and control highlight the detection target of thing to be detected; Or flaw on the thing to be detected or problem such as dirty highlighted, to satisfy the various demands that detect on judging.
Fig. 1 and Fig. 2 are that the line illuminator that discloses tunable optical of the present invention is applied to stereogram and side view on the checkout equipment; As shown in the figure, have on the checkout equipment and use a detection platform 2 of putting, and on detection platform 2, set a detection zone 21, and a CIS 22 is set above detection zone, in order to the image of picked-up detection zone 21 for thing 1 to be detected.
3 of the line illuminators of tunable optical of the present invention are arranged on the detection zone 21 of detection platform 1, required lighting source when CIS 22 picked-up thing 1 image to be detected to be provided.The line illuminator 3 of this tunable optical includes and is the multi-thread type light source 31 of circular arc arch distributed and arranged in detection zone 21 tops, in order to thing to be detected 1 throw light on the detection zone 21; An and light adjusting controller 32 that can carry out the brightness of illumination regulation and control to this linear light sources 31 with wired or wireless mode.Wherein the quantity that is provided with of this linear light sources 31 is regardless of, can be according to actual required number of configured and the light source pattern of deciding, and for example fluorescent tube or the LED lamp bar that constituted by many LED lamp.
Wherein,, be circular arc arch distributed and arranged, so can provide comprehensive and not have the radiation source at dead angle detection zone 21 in these detection zone 21 tops owing to be arranged in that this multi-thread type light source 31 of (or on thing to be detected 1) is the center with detection zone 21 on the detection zone 21; Light adjusting controller 32 then is to carry out the adjustment of luminous intensity respectively to individual other linear light sources 31.
See also shown in Figure 3; More specifically, light adjusting controller 32 includes a plurality of current control devices 321, in order to be electrically connected with different linear light sources 31 respectively; Thus; Specific linear light sources 31 can reach the luminous intensity that this linear light sources 31 of control is launched by the size of connected current control device 321 adjustment electric current outputs, obtains by bright to dark intensity variation.
See also another enforcement illustration that Fig. 4 takes off, mainly between thing 1 to be detected and this multi-thread type light source 31, further be provided with a smooth diffuser 4, use so that the light that throws from this multi-thread type light source 31 evenly spreads back directive thing 1 to be detected.Wherein, This light diffuser 4 is cover bodies that section is the circular arc arch; This light diffuser 4 is smooth dispersive mediums; Because this light diffuser 4 is set between thing 1 to be detected and this multi-thread type light source 31, let the light of linear light sources 21 directive light diffuser 4 when seeing through this light diffuser 4, produce diffusion, make that the light that projects on the thing 1 to be detected is even and soft.
In addition; Please consult Fig. 1 and Fig. 2 again; The line illuminator of tunable optical of the present invention more can further comprise a light compensating apparatus 5; This light compensating apparatus 5 can provide with this CIS 22 detection sides to an identical axis light (in figure shown in the dotted line), increase light source from these CIS 22 directions.More particularly, this light compensating apparatus 5 can a linear light sources 51 and 52 compositions of a spectroscope.Spectroscope 52 is arranged in the path of these CIS 22 picked-up images; After the light that this linear light sources produced is reflected; Form be incident in together on the thing 1 to be detected and with this CIS 22 detection sides to identical radiation source, increase light source from CIS 22 directions.Wherein, aforesaid linear light sources 51 comprises but is not limited to fluorescent tube or the LED lamp bar that is made up of many LED lamp.
As shown in Figure 3; Wherein, Also has a current control device 322 in the light adjusting controller 32 to be electrically connected, in order to do making linear light sources 51 also can reach the luminous intensity that this linear light sources 51 of control is launched by the size of current control device 322 adjustment electric current outputs with this linear light sources 51.
Can know that in sum all linear light sources of being taken off among the present invention (comprising the linear light sources 51 in the light compensating apparatus 5) all can be adjusted luminous intensity individually, in order to produce direction light at any angle; When its purpose is to be applied on the checkout equipment; Can be according to material, shape, concave-convex surface state or the degree of reflection of thing to be detected itself; By specific linear light sources is implemented brightness control; Reach the detection target that highlights thing to be detected, or flaw on the thing to be detected or problem such as dirty are highlighted, to satisfy the various demands that detect on judging.
For instance, have a boss on the thing for example to be detected, then directional light can make the place backlight of boss produce shade, just can utilize this shade by this, carries out the lug boss bit position or the discriminating of rising height; Hence one can see that, and the line illuminator of tunable optical of the present invention promptly can be used for differentiating thing to be detected of unlike material, shape, concavo-convex, degree of reflection etc.
The above is merely preferred embodiment of the present invention, is not to be used for limiting the scope that the present invention implements, and the equalization of doing according to claim of the present invention such as changes and modifies, and is all claim of the present invention and contains.
