The width of described vice-belt is the 1/3 of main belt width.The width design of vice-belt is avoided wide, is that laser instrument is unable to reach large-area optimal illumination effect, and CCD camera cannot photograph optimal angle, causes the inaccurate of late detection result in order to avoid the width of main belt and pair conveyer belt composition is wide.
Described CCD camera is between workpiece sensing localizer and laser instrument, and laser instrument, CCD camera and workpiece sensing localizer are arranged in order from main belt porch, and are positioned on straight line.Laser instrument is positioned at main belt porch, it is possible to preferably illuminate the object entered, and object is taken clear photograph by convenient CCD camera below, improves the precision automatically identified further.
Described CCD camera can any rotation.According to the difference of entrance conveyer belt object space, by the positioning scenarios of workpiece sensing localizer, adjust the shooting angle of CCD camera, obtain optimal shooting picture, in order to the later stage can quickly realize automatically identifying.
Described workpiece sensing localizer can any rotation.Fast and easy location testee.
Compared with prior art, the beneficial effects of the utility model are:
1, for various sizes of detection object, conveyer belt can be adjusted according to the width of object, makes part be positioned on optimal path and moves and carry out vision-based detection, thus improves the requirement automatically identifying different size object degree of accuracy.
2, using laser instrument in this programme is light source, even if life-time service also will not produce decay compared with LED light source, light source is more stable, the veiling glare around laser beam is filtered by pinhole filter, avoid the veiling glare impact on testing result, beam expanding lens and collimating mirror make laser beam become directional light the checked metal sheet surface of angle of incidence Uniform Illumination with 45 degree simultaneously, so that CCD camera can photograph clear photograph be transferred to image pick-up card, metal surface detection is carried out for the later stage, this detection avoids the scuffing to metal surface, also avoid the extraneous veiling glare impact on measurement result, final testing result is accurately and guarantee fund's metal surface intact.
