Detailed description of the invention
By describing technology contents of the present utility model in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
The design of the utility model most critical is: adopt the filter of rotary type to carry the optical filter of different colours, thus change the lighting effect of light source irradiation on measured object, analysed and compared and the defect that finds it to exist according to being passed easily through by comparison after lower successively by camera.
Refer to Fig. 1 and Fig. 2, a kind of light-source structure of visual quality checkout equipment, comprises light source 10, filter 20 and drive unit 30; Described filter 20 is provided with the different optical filter 21 of many groups; Described drive unit 30 is connected with filter 20, and drive unit 30 rotates for driving filter 20; Described light source 10 is fixed on above the track of the circular trace of optical filter 21 formation of rotating with filter 20.
From foregoing description, the beneficial effects of the utility model are: relative to the product only configuring single light source, this programme is when carrying out visual quality and detecting to product, the light that light source sends produces the lighting effect of different colours continuously under the effect of the optical filter rotated on measured object, camera is by taking the photo that can obtain under different light effect continuously, be conducive to the different photos of detection system to measured object like this to analyse and compare, thus the fault location of measured object can be found more accurately; Meanwhile, relative to arranging multiple light source and compare to the scheme that each light source configures separately the optical filtering of a different colours simultaneously, this programme significantly can reduce equipment cost.
Further, as shown in Figure 2, many group optical filters 21 connect into and are arranged in annularly on filter 20.
Seen from the above description, the optical filter being arranged to ring-type is continuously conducive to most generating continuous print lighting effect, is conducive to the continuous candid photograph of camera.The length (circumferential length) of single group optical filter and the rotating speed (linear velocity) of filter, camera take pictures interrelated between frequency, such as optical filter length 50mm, the linear velocity of filter at optical filter place are 1500mm/min, then when the shutter of camera is set to 2s/ time, 1 photo is taken under the lighting effect that can produce at same optical filter, when the shutter of camera is set to 1s/ time, under the lighting effect that can produce at same optical filter, take 2 photos.
Further, consult Fig. 3, also comprise light source track 40 and mobile assembly 50; Described light source track 40 is arc track, the position of the center of circle residing for measured object 100 of light source track 40; Described mobile assembly 50 is located on light source track 40, and light source 10, filter 20 and drive unit 30 are arranged on mobile assembly 50.
Seen from the above description, the position of mobile light source can be facilitated by arranging light source track and mobile assembly, thus carry out vertical irradiation to the different surfaces of the comparatively complicated measured object of profile, and then the different surfaces making camera can photograph measured object is in the picture under the state accepting light source vertical irradiation.And the center of circle of light source track is set as measured object position, be in order to ensure no matter moving which position that assembly moves to light source track, light source is all equal with the distance of measured object, avoids light and shade to change and causes detecting misalignment.
Further, described mobile assembly comprises running part and installation portion, and described running part is for be connected on described light source track and to walk on light source track, and described installation portion is for installing described light source, filter and drive unit.
Seen from the above description, running part moves the automatic walking of assembly by certain control realization, thus avoids by manually adjusting comparatively to mobile assembly, causes using the problem of comparatively inconvenience.
Further, described light source track 40 is provided with many groups, and described mobile assembly 50 and described light source 10, filter 20 and drive unit 30 are also provided with many groups matchingly with it.
In the diagram, light source track 40 is provided with two groups, until measured object 100 be transferred band 300 be sent to detect station 400 time, two groups of cameras 200 of coupling and light source 10, filter 20 and drive unit 30 collaborative work, by 45 of both sides before and after measured object degree of oblique shootings carried out under different colored light sources.
Seen from the above description, can carry out vertical irradiation to the more different surfaces of the comparatively complicated measured object of profile further by multiple sets of light sources track, and then the different surfaces making camera can photograph measured object is in the picture under the state accepting light source vertical irradiation.
Please refer to Fig. 1 to Fig. 4, embodiment one of the present utility model is: a kind of light-source structure of visual quality checkout equipment, comprises light source 10, filter 20, drive unit 30, light source track 40 and mobile assembly 50.
Drive unit 30 is connected with filter 20, and drive unit 30 can be a kind of small-sized motor, and filter 20 can be directly installed in the rotating shaft of this motor, and driven by motor filter 20 rotates.Filter 20 is provided with organizes different optical filters 21 more, and many group optical filters 21 connect into and are arranged on filter 20 annularly, and light source 10 is fixed on above the track of the circular trace of optical filter 21 formation of rotating with filter 20.
Light source track 40 is arc track, the position of the center of circle residing for measured object 100 of light source track 40; Mobile assembly 50 comprises running part and installation portion, and running part to be used for being connected on light source track 40 and to walk on light source track 40, and installation portion is for installing light source 10, filter 20 and drive unit 30.
In the present embodiment, light source track 40 is provided with two groups, and mobile assembly 50 and light source 10, filter 20 and drive unit 30 are also provided with two groups matchingly with it.
In actual use, camera 200 needs the detection faces be taken to be located at measured object 100 according to measured object 100 to advance the outside of track, and light projector is carried out to measured object 100 in the somewhere that light source 10 is fixed on light source track 40 by mobile assembly 50; When measured object 100 enters test point, filter 20 rotates under the drive of drive unit 30, thus the light making light source 10 be incident upon on measured object 100 by optical filter 21 converts different colors continuously, and the shooting that after each conversion, camera 200 all can carry out at least one times to measured object 100.Finally, imaging under the illumination of different colours is delivered to industrial computer after being detected program reading and is judged, blemish under different light has and different presents precision, such as certain under ruddiness and unconspicuous defect clearly can be identified by industrial computer under blue light, so can improve the degree of accuracy of identification.
In sum, the light that the light source of the light-source structure of the visual quality checkout equipment that the utility model provides sends produces the lighting effect of different colours continuously under the effect of the optical filter rotated on measured object, also under different angles, light projector can be carried out to measured object, camera, by taking the photo that can obtain under different light effect, different angles continuously, is conducive to the fault location finding measured object more accurately like this; Meanwhile, the cost of this programme is also lower.
