Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched
The embodiment stated is only the utility model part of the embodiment, rather than whole embodiments.Based in the utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of the utility model protection.
Fig. 1 shows the shape and structure figure of magnetic shoe in the utility model.As illustrated, the surface of magnetic shoe includes：Intrados,
Extrados, two end faces, two sides face.The radian of magnetic shoe is larger, and internal and external cambered surface, end face, side Mian Deng surfaces are more, while defect
Also it is more.The defects of magnetic shoe, includes dorsal fissure, chink, side are split, interior burst check, end face is split, angle collapses, it is scarce to collapse, sticking to mould, mill is askew, it is complete not grind,
The number of drawbacks of impurity and salient point etc. ten, different defects and different surfaces need different polishing modes, thus need multiple stations
Detected.Wherein, it is due to a shallower polishing trace of uneven formation of polishing during magnetic shoe grinding to grind askew defect
Mark, it is not easily distinguishable with furvous magnetic shoe background, thus needs individually to take phase system.Other defect is then needed according to magnetic shoe not
Carry out taking phase with surface.
According to side face and defect kind, the magnetic shoe defects detection provided by the utility model based on machine vision takes phase system
It is divided into following module：The askew detection of intrados/extrados mill takes phase module, and the detection of 1/2 extrados other defect takes phase module,
The detection of intrados other defect takes phase module, and planar defect detection in side takes phase module and plate defectses to detect and take phase module.Fig. 2 shows
The general structure schematic diagram that magnetic shoe defects detection of the utility model based on machine vision takes phase system is gone out.Wherein, based on machine
The magnetic shoe defects detection of device vision take phase system include the askew detection of intrados/extrados mill take phase module 01,1/2 extrados other
Defects detection takes phase module 02, the detection of intrados other defect to take phase module 03, the detection of side planar defect to take phase module 04 and end
Planar defect detection takes phase module 05.
Further, because intrados and extrados are arcwall face, thus it is used take phase system structure it is identical, only point
Different station.It is a shallower vestige to grind askew defect, and position is not fixed, thus the askew detection of magnetic shoe intrados/extrados mill takes
Phase module uses the red strip source that wavelength is longer, reflectivity is higher.Cause light with lacking light source adjustment angle during detection
Sunken surface is at an angle.In order to cover whole magnetic shoe, it is necessary to 2 red bar light polishings above the side of magnetic shoe inner-outer cambered surface.

Frame 4, is fixed on crossbeam, unclamps trip bolt, can adjust light source along this direction along cross beam movement.Camera is fixed on magnetic shoe
Surface and take phase for shooting.
Magnetic shoe intrados/extrados mill is askew to be detected and takes the phase process that takes of phase module to be：Two bar radiants are adjusted to close
Right position, which is put, makes magnetic shoe be located at source region center, adjusts light-source angle so that two strip sources illuminate respectively when opening respectively
1/2 arc length of magnetic shoe.A strip source is first turned on, closes another, carries out taking phase for the first time, if defect exists
The region that this light source illuminates, then mill askew defect part in this region is dimmed, and background is brightened, and defect is effectively distinguished with background.Together
Reason, turns off this light source, opens another strip source, taken phase for the second time, if defect in the region that this light source illuminates,
This region askew defect part of mill is dimmed, and background is brightened, and defect is effectively distinguished with background.It can be obtained after being taken phase twice
Complete internal and external cambered surface picture.
Fig. 4 shows that the detection of the extrados other defect of magnetic shoe 1/2 takes the light source position schematic diagram of phase module.Due to extrados
Radian is big, and the depth of field is big, and once taking mutually can not realize preferable effect.Therefore using phase is taken twice, take every time outside phase half
Cambered surface, thus select two 1/2 extrados detection stations.The detection of the extrados other defect of magnetic shoe 1/2 takes the light source of phase module to take
With the blue dome light of 1 highlighted homogeneous soft, the uniform light distribution for sending light source, curved surfaces out-of-flatness is effectively eliminated
The interference of formation, light center and camera center line are in 1/4 circular arc normal direction.2 white bars light in the extrados of magnetic shoe 1/2 two
