Specific embodiment
As shown in Figure 1 to Figure 3, embodiment one：
A kind of optical system for the detection of side of the object image information described in the utility model, including whirligig 1,
Light source assembly 2, mirror assembly, camera 4 and pedestal 5 for gathering the side image information of workpiece 100.
The whirligig 1 has the rotation base station 11 that can be rotated around vertical rotation centerline.The workpiece 100 is put
It is put on rotation base station 11, the rotation base station 11 can drive workpiece 100 to be located at rotation in workpiece 100 and vertically extending around one
Turn center line（Rotate the rotation centerline of base station 11）Rotation.
The light source assembly 2 is placed in the periphery of workpiece 100 and can form the light beam impinged upon on workpiece 100.The workpiece 100
Diffusing reflection is formed under the irradiation of light beam.The mirror assembly includes being placed in the speculum 3 in the outside of workpiece 100, the reflection
Mirror 3 can at least receive in the surface diffusing reflection of workpiece 100 light beam for projecting and the incident beam not blocked by workpiece 100
Plant light beam and reflect away it.The camera 4 obtains the light beam of the reflection of speculum 3 so as to form workpiece 100 by camera lens 41
Side image information.The camera lens 41 of the camera 4 is located in the light path of the reflected beams of speculum 3, when workpiece 100 rotates
When, the camera 4 can be by the image information of multiple compartment of terrain shooting, collecting to the side of workpiece 100 multiple visual angle.
Specifically, the light source assembly 2 includes backlight 21 and coaxial light source 22.The backlight 21 and coaxial light source
22 are area source.The optical system also includes the pedestal 5 for installing backlight 21 and speculum 3.The rotation base station
11 are located at the lower section of pedestal 5.The front side portion of the pedestal 5 offers U-shaped breach 51.The rotation base station 11 can be from breach 51
Place is into pedestal 5 and holding workpiece 100 makes workpiece 100 expose in the upper surface of pedestal 5,3 points of the backlight 21 and speculum
It is located on the upper surface of pedestal 5 of the left and right sides of workpiece 100.The backlight 21 and speculum 3 can be moved left and right on pedestal 5
Spacing between the two is adjusted, so spacing can be adjusted according to the workpiece size for being detected, improve the applicability of optical system.
Backlight 21 is detachably accepted on pedestal 5, in such manner, it is possible to the size according to workpiece 100 changes backlight 21, further
The applicability of optical system is improve, a tractor serves several purposes is realized.
The speculum 3 is 45 ° of speculums.The camera 4 is located at the top of speculum 3, the court of camera lens 41 of the camera 4
Under, the scope of the reflected beams of region overlay speculum 3 that the camera 4 can shoot.So, camera 4 can photograph reflection
The side image information of the workpiece 100 of the reflection of mirror 3.Certainly, speculum can also be the speculum of other angles, such as 30 ° anti-
Mirror, 69 ° of speculums are penetrated, like this, the position of camera 4 is accomplished by adjustment, will not in the surface of speculum 4, and can incline
Tiltedly set, the camera lens 41 of camera 4 is directed at the reflecting surface of speculum 4.This set can be according in the system having
Mechanical structure, locus determine.
As shown in figure 3, the backlight 21 and speculum 3 set up separately in the left and right sides of the workpiece 100.The backlight
21 generation incident beams are radiated at the surface of workpiece 100, and the workpiece 100 can block the incident light of the generation of part backlight 21
Beam, the speculum 3 can receive the portions incident light beam that is not blocked by workpiece 100 and by reflection enter the camera lens of camera 4
In 41.Due to the setting of backlight 21, the workpiece 100 for being directed towards the direction of speculum 4 of the shooting, collecting of the camera 4, and the party
Illuminated by backlight 21 to the edge contour due to only having workpiece 100, thus the camera 4 only can shooting, collecting to the work
The side profile image information of part 100.
As depicted in figs. 1 and 2, the coaxial light source 22 is located between camera 4 and speculum 3, i.e., positioned at the upper of speculum 3
Side.The incident beam that the coaxial light source 22 is produced is radiated on speculum 3 straight down, and the reflection of reflected mirror 3 impinges upon described
The surface of workpiece 100, the surface of the workpiece 100 forms diffusing reflection, and it is unrestrained anti-that the speculum 3 can receive the surface of workpiece 100
The light beam of injection and by reflection inject camera 4 through coaxial light source 22 camera lens 41 in, because coaxial light source 22 is by direction
The surface of workpiece 100 of the side of speculum 4 is irradiated to completely, thus the camera 4 can shooting, collecting to the side of the workpiece 100
Portion's surfacial pattern information, the i.e. graphic design of the side surfaces of workpiece 100, the image information of three-dimensional structure can be by the institutes of camera 4
Photograph.
Camera 4 can all gather the side image information of a week of workpiece 100 during workpiece 100 rotates
Arrive.So, the side image information of the various visual angles of workpiece 100 can just be spliced reduction, and camera 4 is capable of the workpiece of shooting, collecting
The image information of 100 side surfaces is perfect in detail enough.
Certainly, optical system described in the utility model can also only set a backlight 21 for detecting side as needed
Profile image information, or a coaxial light source 22 is only set for detecting the surfacial pattern information of workpiece 100, this can basis
The design parameter for being actually needed the side image information of the workpiece 100 of detection is defined, and this set can be in the inspection for realizing needing
Production cost is reduced on the basis of brake.
As shown in Figs. 4-6, embodiment two：
Embodiment two is on the basis of embodiment one, will to be changed into admittedly for installing the pedestal 5 of backlight 21 and speculum 3
Determine frame 6.
Specifically, the optical system also includes the fixed mount 6 for installing backlight 21 and speculum 3.It is described solid
Determine the plate that frame 6 is L-type, the second plate 62 that its first plate 61 and vertical direction for including horizontal direction extension extend.Institute
The side that the second plate 62 is located at the bottom of the first plate 61 is stated, the present embodiment is arranged on the right side of the bottom of the first plate 61.It is described
The bottom that backlight 21 is arranged on the first plate 61 keeps left position.The speculum 3 is arranged on the inner side of the second plate 62.It is described
The position of correspondence speculum 3 offers the through hole 63 of up/down perforation on first plate 61, and the light beam of the reflection of the speculum 3 can
Via through holes 63 are projected.The rotation base station 11 is located at the lower section of backlight 21 and speculum 3, and the rotation base station 11 can be held
The workpiece 100 moves forward and backward position in the space between backlight 21 and speculum 3.The backlight 21 and speculum 3
Adjustment spacing between the two can be moved left and right on fixed mount 6.In such manner, it is possible to adapt to the streamline detection of workpiece 100.That is edge
Space between backlight 21 and speculum 3, can set the connecting gear of continuous productive process, circulate from front to back, constantly by work
Detected in the feeding optical system of part 100.
As described above, we are illustrated fully according to objective of the present utility model, but the utility model not limits to
In above-described embodiment and implementation.The practitioner of correlative technology field can be in the scope of technological thought of the present utility model license
Inside carry out different changes and implementation.
