Below by described in introducing respectively.
Front end feed zone enters disc platform 1 oil can 2 material loading automatically, and described disc platform 1 center is provided with drive motor, drives disc platform 1 to be moved to discharging end fixed card slot 27 by material loading end fixed card slot 21, completes the robotization transmission of material.
Described disc platform 1 is provided with the mini-roundabout of multiple station, i.e. fixed card slot (21,22,23,24,25,26,27), charging oil can 2 is placed in above mini-roundabout, each mini-roundabout along disc platform 1 sense of rotation respectively through feed position, High Rotation Speed retarder location 22P, backlight bright field position 23P, top light details in a play not acted out on stage, but told through dialogues position 24P, polarisation details in a play not acted out on stage, but told through dialogues position 25P and lower material level 27.The control of disc platform 1 and the motion of above-mentioned mini-roundabout and each station is controlled by industrial computer 5.
Namely around electric machine rotational axis 221 High Rotation Speed after mini-roundabout 22 charging, rotate to be single turning to, emergent stopping after arrival backlight bright field detecting unit.Then entry of backlight bright field position 23P.
The pick-up unit of backlight bright field position 23P by being placed in inner side, disc platform 1 central shaft side, exiting parallel large area first backlight 43 and the camera lens 331 faced outside oil can 2 and the first high speed camera 33 form.Described first high speed camera 33 frame per second is higher, and the motion of disc platform 1 can be ignored the impact of adopting figure.The center line of camera lens 331 is vertical with the first backlight 43 surface, and arranges along the rotation center line of disc platform 1 and mini-roundabout 23, and is positioned at oil can 2 centre position.
It is motionless that first backlight 43 and the first high speed camera 33 are fixed on this station, due to emergent stopping, oil can 2 no longer rotates, but the oil in it is still along its original sense of rotation direction High Rotation Speed, after arrival station 23P, signal is sent to high speed camera 33 continuous acquisition multiple image, preferably more than two width by industrial computer 5.Because opaque impurity is motion under the drive of oil, therefore occur in the picture detecting opaque impurity after several figure subtract each other by the moving image that appearance in static bright background is black.
The fixed card slot 24 of inside cell is just liked in top light details in a play not acted out on stage, but told through dialogues, top light details in a play not acted out on stage, but told through dialogues position 24P is made up of the camera lens be placed in outside exiting parallel large area second backlight 441 at top, the shadow shield 44 being placed in inner side and oil can 2 and the second high speed camera 34, second backlight 441 be placed in oil can 2 top and and fixed card slot 24 be arranged in parallel, camera lens optical axis is arranged along the rotation center line of disc platform 1 and mini-roundabout 24, and is positioned at oil can 2 centre position.Shadow shield 44, in order to block the parasitic light of other stations, reduces interference.It is motionless that second backlight 441 and the second high speed camera 34 are fixed on this station, due to emergent stopping, oil can 2 no longer rotates, but the oil in it is still along original direction High Rotation Speed, after oil can 2 arrives this station 24P, send signal to high speed camera continuous acquisition multiple image by industrial computer 5, because transparent impurity is random motion under the drive of oil, therefore occur in the picture occurring bright moving image in static black background, after several figure subtract each other, detect transparent impurity.
The fixed card slot 25 of polarisation dark field detection unit, polarisation details in a play not acted out on stage, but told through dialogues position 25P is by exiting parallel large area the 3rd backlight 45 being placed in inner side, for (disc platform 1 central shaft side, polarized backlight source, be made up of parallel 3rd backlight 45 and polaroid 451) and the analyzer that faces outside oil can 2 and third high speed camera 35 form, the polarization direction in described polarized backlight source becomes to be arranged vertically with checking bias slice device polarization direction, the center line of camera lens is vertical with light source surface, and the rotation center line of disc platform 1 and mini-roundabout 25 is arranged, and be positioned at oil can 2 centre position.It is motionless that light source camera lens and camera are fixed on this station, due to emergent stopping, oil can no longer rotates, but the oil in it is still along along original direction High Rotation Speed, after arriving this station 25P, signal is sent to high speed camera 35 continuous acquisition multiple image by industrial computer 5, because impurity is random motion under the drive of oil, its athletic meeting changes the polarization direction of incident light, therefore occur in the picture appearance in static dark background bright moving image, detect Polarization-Sensitive all kinds of impurity after several figure subtract each other, that measures as backlight bright field position 23P and top light details in a play not acted out on stage, but told through dialogues position 24P supplements, effective reduction loss.
Described transparent color and luster degree detects fixed card slot 26, and detecting position 26P is by the exiting parallel pointolite 46 being placed in inner side and the optically focused mechanism 361 faced outside oil can, and optical fiber and spectroanalysis instrument 36 form.The center line of light source 46 and camera lens 361 is arranged along the rotation center line of disc platform 1 and fixed card slot 26, and is positioned at oil can centre position.It is motionless that pointolite, optically focused mechanism and spectrometer are fixed on this station.Described parallel pointolite is made up of the good white light of colour rendering and collimation mechanism, described optically focused mechanism 361 assembles the source of parallel light through oil can, and make to enter optical fiber, then spectrometer 36 is entered, described spectrometer provides the intensity data of white light through each spectrum after edible oil inside kettle 2, computer-internal stores the spectrum intensity data of all kinds of standard oil, and after contrast, draw this oil can cast of oil and transmitance data, rotating disk 22 enters unloading position 27P subsequently.
Generally enter after discharge end 27P reject and sort out end, for the oil can containing impurity is rejected, while oil can according to color and luster and transmitance Data classification, not in the description scope of this patent, no longer describe in detail.
So far mini-roundabout 22 drives the oil can 2 it filling oil to complete motion detection process from feed end to discharge end.Other mini-roundabouts 21,23,24,25,26,27 complete above-mentioned same process, rotate back and forth, realize automatic production line and detect.
