The scientific and technological industry of coming in is flourishing day by day, therefore 3C Product is is all researched and developed design towards the direction of miniaturization at present, and as mobile phone, PDA or its screen glass of other computer peripheral product are in manufacture process, more or less all can there be some flaws to produce (as scratch, dust or stain etc.), therefore before dispatching from the factory, must carry out a comprehensive QC trace routine, and the mode that is used to detect glass at present is directly to judge flaw on glass with naked eyes by the QC personnel, and judge detection method with this kind, not only degree of accuracy is limited, more can be after work a period of time, the fatigue that causes eyes is with uncomfortable, and the work efficiency when causing detecting reduces and causes erroneous judgement easily.

The utility model content

Technical problem underlying to be solved in the utility model is, overcomes the above-mentioned defective that prior art exists, and a kind of glass detector is provided, and it can judge glass flaws accurately, the work efficiency when detecting so as to improving, and effectively reduce False Rate.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of glass detector, it is to utilize the light source irradiation mode to detect a glass pieces, it is characterized in that: this glass detector has a detection platform, offer an opening on this detection platform, this opening below is extended with a dark hole, one light-emitting device is to be made of in the annular arrangement mode several light-emitting components, and this light-emitting device is to be arranged in this opening, and in order to produce an annular light source to shine on this glass pieces, one image acquisition unit be in order to acquisition through the postradiation glass pieces image of this annular light source, and this image acquisition unit institute picked image is shown through a screen.

Aforesaid glass detector, wherein the inner edge in dark hole is dark shape.

Aforesaid glass detector, wherein light-emitting device is to be a hollow frame shaped, described each light-emitting component is a framework inner edge of being located at light-emitting device in regular turn.

Aforesaid glass detector, wherein the apical margin end face of light-emitting device and this working face trim mutually, so that several light-emitting components of this light-emitting device are positioned at the inboard periphery of this opening.

Aforesaid glass detector, wherein each light-emitting component shines towards the glass pieces direction according to a predetermined angular respectively.

Aforesaid glass detector, wherein image acquisition unit is a CCD/COMS digital camera camera lens.

Aforesaid glass detector, wherein image acquisition unit is the opening top that correspondence is located at this detection platform, this glass pieces is then on the opening of this detection platform and between this image acquisition unit.

Aforesaid glass detector, wherein the outer peripheral edges of image acquisition unit more can be socketed with a light shield.

And shine on the flaw of glass pieces and when producing shade, be to be the dark hole effect of black by background when this annular light source, so that institute's picked image shade contrasts more obviously, and help the image testing.

The beneficial effects of the utility model are, it can judge glass flaws accurately, the work efficiency when detecting so as to improving, and effectively reduce False Rate.

Embodiment

At first please cooperate and consult Fig. 1 to Fig. 3, be the selected example structure of the utility model shown in the figure.

A kind of glass detector provided by the utility model, it is to utilize the mode of a light source irradiation in a glass pieces 10, to detect the flaw situation on glass pieces surface, and this glass detector mainly is made of a detection platform 11, a light-emitting device 21, an image acquisition unit 31 and a screen 41, wherein:

This detection platform 11, it has a working face 12, and offers an opening 14 on this working face 12, and these opening 14 belows are extended with the dark hole 16 that an inner edge is dark shape (as black);

This light-emitting device 21, be to be a hollow frame shaped, its inner rim is provided with several light-emitting components 22 in regular turn, this light-emitting device 21 is in order in the opening 14 that is located in this detection platform 11, and the apical margin end face of this light-emitting device 21 is to trim mutually with this working face 12, so that several light-emitting components 22 of this light-emitting device 21 are positioned at the inboard periphery of this opening 14, and this each light-emitting component 22 is respectively according to a predetermined angular and towards glass pieces 10 directions irradiations, and forms an annular light source;

This image acquisition unit 31, it is a CCD/COMS digital camera camera lens, and this image acquisition unit 31 and a screen 41 link mutually, these image acquisition unit 31 correspondences are located at opening 14 tops of this detection platform 11, this glass pieces 10 is then on the opening 14 of this detection platform and between this image acquisition unit 31, this image acquisition unit 31 can be in order to acquisition through postradiation glass pieces 10 images of this annular light source whereby, and 31 picked image of this image acquisition unit are to be passed on this screen 41 to be shown again.

The utility model of forming by above-mentioned member is when this annular light source shines in glass pieces 1

On 0 the flaw and when producing shade, by background is dark hole 16 effects of black, and must make 31 picked image shade contrasts of this image acquisition unit more obvious, and via also scalable its shown image of this screen 41, therefore the testing staff is by the shown image of this screen 41, can quite easily judge the flaw on the glass workpiece 10,, and and then promote work efficiency when detecting with the degree of accuracy of effective lifting glass workpiece 10 when detecting.
