Be provided with the water that prevents bottle bottom band between described Polarizer and the optical grade PMMA and enter polaroid, damage the O-ring seal of polaroid.
Described location triggered sensor is that photoelectric type position triggers sensor.
The utlity model has following advantage:
Because this device has adopted high stroboscopic light source in the bottle end and a pair of polarizing appliance and high speed camera to realize the collection of high speed image, transparent foreign matter at the bottom of can discovery bottle clearly in image, and adopt high-velocity electrons shutter and the uniform stroboscopic light source of high brightness, preferably resolve defectives such as smear that the dynamic image collection exists is fuzzy, generation brightness is even, contrast is high quality image clearly, has reduced follow-up image processing time and bottle and has rejected error rate.In addition because the setting of polarisation filter, utilize polarisation of light characteristic and Polarizer that the light vibration of different directions is had and select the performance that absorbs, by regulating the angle of two polarizing appliances, can obtain the transparent foreign matter image of high-contrast.The dazzle on smooth glass surface can also be eliminated or weaken to polarisation filter on the camera lens simultaneously, shows the details and the feature of transparent foreign matter better.Again owing to adopt the strobe mode illumination so can obtain 20 times the brightness that normal bright mode is thrown light on, thus the brightness that has improved light source, and increased serviceable life of light source, eliminate the interference of ambient light.
Adopt the polishing gimmick of back lighting, like this according to the shape facility of bottle and detect content, the edge contour of measured object can be sketched the contours of clearly, because in image, the place that measured object blocked is a black, unscreened place is a white, forms in white and black image that is easy to image analysis.
Since adopt the stroboscopic controller to control the flicker of led light source, and synchronous with the exposure time maintenance of high speed camera, can obtain the motion video of " solidifying " no smear, for guaranteeing clear being very helpful of transparent foreign matter imaging.
Description of drawings
Fig. 1 is the pick-up unit structural representation that the utility model is used for the transparent foreign matter of high-speed cruising glass empty bottle.
Embodiment
Below in conjunction with accompanying drawing the pick-up unit that the utility model is used for the transparent foreign matter of high-speed cruising glass empty bottle is further described:
As shown in Figure 1, the utility model is used for the pick-up unit of the transparent foreign matter of high-speed cruising glass empty bottle, comprise the clamping and conveying device 10 that glass empty bottle 5 is transported to inspection positions, be successively set on the high stroboscopic light source 8 in the bottle end on the empty bottle axial direction of empty bottle inspection positions, Polarizer 7, optical-grade transparent glass (as organic clear glass PMMA) 6, and high stroboscopic light source 8 direction of illuminations and the high speed camera 2 of camera lens 3 is installed at the bottom of being arranged on bottle, on camera lens 3, be provided with polarisation filter 4, this device comprises that also empty bottle 5 arrives the location triggered sensor 9 and the Programmable Logic Controller 1 of inspection positions, Programmable Logic Controller 1 is responsible for receiving position and is triggered the signal that sensor is sent, send synchronizing signal to bottle at the bottom of high stroboscopic light source 8 and high speed camera 2, trigger that high speed camera 2 is gathered image and high stroboscopic light source 8 glimmers.Location triggered sensor 9 triggers sensor for photoelectric type position.Also be provided with the rotation circle of adjusting best transparent foreign matter imaging effect by the angle between adjusting and the Polarizer 7 on the camera lens 3.Because led light source is compared with conventional light source, has following long service life, the brightness height, response speed is fast, and advantages such as shape freedom are so the high stroboscopic light source 8 in the bottle end is high stroboscopic LCD backlight.On high stroboscopic light source 8 at the bottom of the bottle, also be provided with the flicker of control LCD and keep synchronous stroboscopic controller with the exposure time of high speed camera.For the water that prevents bottle bottom band enters polaroid, damage polaroid, between Polarizer 7 and optical grade PMMA6, be provided with O-ring seal 11.
