Such as Fig. 1, this utility model embodiment provides the image collector of a kind of electronic plane glass defect detection
Putting, this device includes being arranged at the source of parallel light 02 above tested electronic plane glass 01, by directional light
The directional light that source 02 sends invests the spectroscope 03 of electronic plane glass 01, is arranged at electronic plane glass 01
Top and the linear light sorurce 04 of oblique illumination electronic plane glass 01, be arranged at below electronic plane glass 01
Backlight 05, be arranged at the reflection light and thoroughly for receiving electronic plane glass 01 above spectroscope 03
Penetrate the camera lens 06 of light, and be connected to gather the camera 07 of image with camera lens 06.Specifically, spectroscope
03 has reflection and the dual-use function of transmission, and its splitting ratio can be designed as 50:50, light splitting by the present embodiment
Directional light can be reflexed to electronic plane glass 01 by mirror 03, and is reflected by electronic plane glass 01 and thoroughly
The light penetrated is transmitted through camera lens 06 for imaging.The linear light of the exportable certain rising angle of linear light sorurce 04,
This linear light oblique illumination electronic plane glass 01.The exportable directional light of backlight 05 or linear light form
Backlight, this backlight is difficult to, through electronic plane glass 01, then may pass through in non-printed areas at printing zone
Electronic plane glass 01.Camera lens 06 is arranged at the top of spectroscope 03, by electronic plane glass 01 upwards
Reflection and the light of transmission are collected by this camera lens 06, and are sent to camera 07 for imaging, and then pass through institute
The defect of the digital image analysis electronic plane glass 01 as being arrived by collected by camera become.
Its operation principle of defects detection example in detail below by way of concrete:
Such as Fig. 2, directional light is used to detect, when directional light is vertical or near normal irradiates electronic plane glass
During glass 01, flawless part generation direct reflection, directional light upwards can be reflected, and through light splitting
Mirror 03 enters camera lens 06 and camera 07, forms brighter background, defective (such as foreign body or print bad)
Place then there is diffuse-reflectance, upwards reflect little light and enter camera 07, form dark defect, therefore,
The image of camera 07 shooting is the dark defect in brighter background.
Such as Fig. 3, use linear light to detect, when linear light oblique illumination electronic plane glass 01, press
According to principle of reflection, flawless part by incident illumination inclined reflection, and then can will not enter camera 07, imaging
Time be presented as relatively dark background, the part of defective (such as foreign body or print bad) then can be due to diffuse-reflectance
And reflect a part of light and enter camera 07, form brighter defect, therefore, the image of camera 07 shooting is
Compared with the brighter defect on dark background.
Such as Fig. 4, backlight is used to detect, when linear light or directional light upwards irradiate electronic plane glass
When 01, for there being the region of printed patterns, flawless fractional transmission is less, and backlight cannot be introduced into camera 07,
Forming relatively dark background, the part of defective (as pattern lacks) then can enter camera 07 by transmission light, be formed
Compared with the brighter defect on dark background.Such as Fig. 5, for the region of non-printing pattern, flawless part is whole
Or major part transmission, backlight enters camera 07 and forms brighter background, and the part of defective (such as foreign body) is then
Will not transmission or few transmission, the image of camera 07 shooting is the dark defect in brighter background.
Visible by drawbacks described above detection example, the image collecting device of the present embodiment is by directional light, linear
Light and backlight, as illumination light, are shot the image of electronic plane glass 01, can detect difference by camera 07
The defect of type so that the defects detection efficiency of electronic plane glass 01 and effect are greatly improved.And should
Image collecting device is simple for structure, it is simple to manipulation, is suitable for the application in industry.
