Abstract
The invention discloses an apparent defect detection method, which can rapidly detect the apparent defect of touch screen protective glass and is suitable for batch flow detection application on production lines, for the touch screen protective glass. The detection method replaces original manual detection mode, is high in detection speed, uniform in detection standards, low in omission ratio, lower in the labor intensity of operating personnel, and higher in the overall detection efficiency and quality of touch screen protective glass, adopts automatic optical visual detection, and can effectively solve problems of manual detection.
Description
Technical field
The present invention relates to a kind of glass appearance defect inspection method, particularly a kind of touch screen protective glass appearance defect inspection method.
Background technology
Touch screen protective glass is through the ultra-thin glass meeting touch-screen industry requirement of chemical tempering process.Along with American apple company releases iPhone mobile phone and iPad panel computer, greatly facilitate the commercialization of touch-screen, meanwhile the sector is all the more made clear the specification of touch screen protective glass and test stone and strictly.
The technological process of production of touch screen protective glass comprises: sawing sheet, CNC, plain grinding, acierage, silk-screen and baking etc.In these machining processes, than being easier to produce that surface tear, edge collapse limit, dirty, Sha Bian, embossing, watermark, button foreign material, button are bitten, the open defect such as IR foreign material and ink foreign material.These defects can affect serviceable life and the outward appearance sensory effects of touch screen protective glass, therefore need to be checked out by the sample with bad defect, to improve the end product quality that dispatches from the factory in the technological process of production.
At present, most of touch screen protective glass production manufacturer adopts artificial visual viewing method to detect product appearance defect.Adopt manual detection mode to there is a lot of problem, such as detection speed is lower, eye fatigue, examination criteria are difficult to unification, loss is high.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of open defect that can detect touch screen protective glass fast, being applicable to producing batch flowing water on line and detecting the touch screen protective glass appearance defect inspection method of application.
The present invention in order to the technical scheme solving its technical matters and adopt is: a kind of touch screen protective glass appearance defect inspection method, comprises the following steps:
1) be placed on a sample delivery device by tested glass sample, described sample delivery device can drive sample to do rectilinear motion on guide rail, and the top of sample delivery device is provided with two lighting sources, and a photographing camera;
2) mobile example conveying device, is sent to successively by the glass sample be placed on sample support frame below the photographing camera of front;
3) front photographing camera completes the seizure to glass sample surface image, and view data is sent to computing machine;
4) finally complete image procossing by computer program and analyze the defect information of sample.
As a further improvement on the present invention, above and below described sample delivery device, be equipped with at least two lighting sources, and some transversely arranged photographing camera.
The invention has the beneficial effects as follows: touch screen protective glass appearance defect inspection method of the present invention instead of original manual detection mode; its detection speed is fast, examination criteria is consistent, loss is low; also reduce the labour intensity of operating personnel; improve whole detection efficiency and the quality of touch screen protective glass; this detection method adopts automated optical vision-based detection, can effectively improve manual detection Problems existing.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the inventive method;
Indicate in figure: 1-sample delivery device; 2-guide rail; 3-lighting source; 4-photographing camera.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
Fig. 1 shows a kind of embodiment that glass appearance defect inspection method is protected in inventive touch screen protection, comprises the following steps:
1) be placed on by tested glass sample on a sample delivery device 1, described sample delivery device 1 can drive sample to do rectilinear motion on guide rail 2, and the top of sample delivery device 1 is provided with two lighting sources 3, and a photographing camera 4;
2) mobile example conveying device 1, is sent to successively by the glass sample be placed on sample support frame below front photographing camera 4;
3) front photographing camera 4 completes the seizure to glass sample surface image, and view data is sent to computing machine;
4) finally complete image procossing by computer program and analyze the defect information of sample.
