Among the figure: upper flange 1, attachment screw 2, briquetting 3, optical fibre ring illumination head 4, screw 5, transparent light corn 6, reflective taper 7, anti-fall screw 8, lower flange 9, anti-sliding sleeve 10, column type connector 11, anti-fall briquetting 12, bolt 13, circular port 14.Bolt 13 is coupling bolts of 9 of anti-fall briquetting 12 and lower flanges.
Embodiment
As shown in Figure 1, the present invention includes upper flange 1, lower flange 9, column type connector 11, optical fibre ring illumination head 4, transparent light corn 6 and reflective taper 7, its annexation is: upper flange 1 is connected with column type connector 11 by attachment screw 2; Briquetting 3 by screw retention on upper flange 1; Lower flange 9 is connected with column type connector 11 by screw thread; Optical fibre ring illumination head 4 is fixed on the column type connector 11 by screw 5; Transparent light corn 6 is placed on the lower flange 9, the inwall clearance fit of transparent light corn 6 tops and optical fibre ring illumination head 4, and the top of reflective taper 7 and column type connector 11 clearance fit, the lower end is connected with lower flange 9 by anti-fall briquetting 12 and bolt 13.Anti-fall screw 8 is fixed on the column type connector 11 by being threaded; Lower flange 9 is connected with column type connector 11 by screw thread; Anti-fall briquetting 12 is fixed on the lower flange 9 by bolt 13, utilizes this briquetting that reflective taper 7 is connected with lower flange 9.The periphery of lower flange 9 is provided with anti-sliding sleeve 10, and this anti-sliding sleeve is made by rubber.
It was as follows originally to work: pass through the reflection of reflective taper 7 after the refraction change angle of light by transparent light corn 6 by 4 emissions of optical fibre ring illumination head again, the diffuse light that forms multiple angles at last shines the end face of PCB drill bit by the circular port on the lower flange 9 14, obtains to satisfy image and detects the illumination that requires.By regulating being threaded between lower flange 9 and the column type connector 11, lower flange 9 is moved up and down, move up and down along the axle center of column type connector 11 thereby drive reflective taper 7 and transparent light corn 6, reach the effect of the angle of adjusting emergent ray.Anti-fall screw 8 is to be used for preventing lower flange 9, emission light cone 7 and 6 tenesmus of transmission light cone, can also control the moving range of reflective taper 7, transmission light cone 6 and lower flange 9 simultaneously by its length that is screwed into.
By Fig. 2,3,4,5 as can be known, do not reach the requirement of detection with the image of axis light and ring light illumination acquisition, the image that obtains with annulus fluorescent pipe illumination is owing to can not carry out the adjusting of light intensity, and there is bigger distortion in the image of acquisition, is difficult to satisfy accuracy requirement with this image measurement.In the lighting device of design voluntarily, the light that sends from the optical fibre ring cold light source is after the inside surface reflection of reflective taper, form uniform diffuse reflection, again after the sword face reflection via little brill, most light enters CCD, therefore the image definition height that obtains, distortion are little, can satisfy the needs of measurement.Experiment by reality shows: adopt apparatus of the present invention can obtain to be out of shape the PCB image little, high-quality, that sharpness is high as lighting system, thereby the detection that makes the PCB drill bit becomes automatic image by artificial sampling observation to be detected and becomes possibility, to the quality that improves product, reduce cost and enhanced productivity important practical value.
