Description
Technical field
The utility model is related to machine visual detection device field, specially a kind of machine vision checks equipment.
Background technology
Machine vision checks that equipment can carry out currency or coin the grade of non-artificial defect recognition, classification and defect
The detections such as quantization, to eliminate the subjectivity and consistency of artificial detection.Traditional machine vision checks that the LED light source of equipment is universal
Optically focused is carried out using single cylindrical lens, LED particle is typically that axially meridian arranges with certain spacing, LED
Grain center is vertical with dioptric meridian, and the light emitting angle of LED lamp bead itself is larger (generally at 120 °) in addition, and cylindrical lens is axial
Meridian direction does not have refractive power for the light that LED particle issues, and is by each LED so in axial meridian direction
The light for all directions that particle issues overlaps out；And in dioptric meridian direction, there is dioptric effect to light, therefore
What is come out after cylindrical lenses is a highlighted light belt.It is more in disorder in axial meridian direction radiation direction, do not have
Consistency, it is unfavorable for surface defects detection.And traditional machine vision checks that equipment is each using annular light source or the right and left
One light source is tiltedly beaten, line scan camera
Sensor orientation is parallel with the light belt of light source and perpendicular to shooting target surface.Two light sources are same in actual use
What Shi Kaiqi was persistently lighted, and it is more in disorder in axial meridian direction radiation direction, do not have consistency, in addition most of
Defect is smaller, and crease area is essentially the same with the imaging gray value of near zone, is unable to reach the contrast needed for detection.Therefore
Most folding line, cut, protrusion, recess can not be all imaged on camera on shooting target surface.Therefore the utility model will solve
The technical issues of be to provide a kind of efficient machine vision and check equipment.
Utility model content
The purpose of this utility model is to provide a kind of machine vision to check equipment, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides the following technical solutions：A kind of machine vision inspection equipment, including machine
The bottom of frame, left cabinet, right cabinet and control cabinet, the rack is provided with non-slip mat, and the left cabinet and right cabinet distinguish position
In the left and right ends of rack, the control cabinet is located at the intermediate position of left cabinet and right cabinet, is provided with out in the left cabinet
Winding up roller is provided with wind-up roll in the right cabinet, and first light source, second light source, first camera, second camera and labelling machine are all pacified
In the control cabinet in rack, the first camera is mounted on the right side of unwinding roll, and the second camera is mounted on wind-up roll
Left side, the first light source and second light source be mounted on the intermediate position of first camera and second camera, and first camera with
The both sides of the region of camera lens face first light source and the second light source irradiation of second camera, the unwinding roll and wind-up roll are equipped with
Guide roller, respectively the first guide roller, the second guide roller and third guide roller, the labelling machine are mounted on the first guide roller and the
Between two guide rollers, fax unit is additionally provided on the left of the rack, and image processing unit is additionally provided on the right side of rack.
Further, the centre of the first camera and second camera is equipped with stroboscopic controller.
Further, the first light source, second light source, first camera, second camera and stroboscopic controller are electrical connected.
Further, the first light source and second light source are unidirectional strip source.
Further, the angle of the first light source and second light source and target surface is 20 ° to 60.
Compared with prior art, the utility model has the beneficial effects that：The utility model uses two one direction skew rays
The sunny side in source and defect, therefore the light for being reflected into camera is more, obtained gray value of image is higher, and the back carries light side
To, it is less by light irradiation, it is relatively low to obtain gray value of image；Since blemish surface is rough, sunny side reflection light is also each
A direction is all existing, but back reflection light cannot be introduced into camera lens, even without reflection light, therefore back gray value
Or it is far below sunny side.Defect area is because having negative and positive two sides, defect also just to be displayed.Therefore picture contrast obtain into
One step improves, and can greatly improve defect detection rate.In addition the utility model overcomes subjectivity existing for personnel's visual detection
By force, the high disadvantages such as low with detection efficiency of False Rate, accelerate detection speed, improve production efficiency, reduce production cost, real
Show and detection quality has been timely feedbacked, the producer can have been made to find the problems in production process in time, the ginseng of adjustment production in time
Number, to improve yield rate and quality；In addition, by the way that stroboscopic controller is arranged, the output signal of camera can be effectively adjusted.
