Description
本發明係關於一種玻璃檢測系統及其方法，尤其是一種能夠同時縮短檢測時間，且對玻璃之表面及斷面的切割處進行檢測的檢測系統及其方法。 The present invention relates to a glass detecting system and method thereof, and more particularly to a detecting system and method for simultaneously detecting a cutting time of a surface and a section of a glass, which can simultaneously shorten the detecting time.
玻璃經過切割及裂片後，若其表面或斷面產生毛邊、缺口或刮傷等缺陷時，將會使玻璃的精密度或強度受到影響，進而造成後續使用上的風險，為此，必須檢測其表面及斷面的切割處以確定沒有上述缺陷產生。 After the glass has been cut and lobed, if the surface or section has defects such as burrs, nicks or scratches, the precision or strength of the glass will be affected, which will cause subsequent risks. For this reason, it must be tested. The cut of the surface and section to determine that no such defects have occurred.
習知玻璃檢測技術，係以一種自動對焦(AutoFocus)的雷射檢測器對玻璃進行檢測，同時使用二雷射檢測器進行檢測時，會互相造成干擾而影響檢測的精確度，因此，只能依序或反序對玻璃之表面及斷面的切割處先後進行檢測，進而拉長整體的檢測時間。此外，雷射檢測器亦有可能因為玻璃厚度的太薄，而導致無法對玻璃之斷面的切割處進行檢測，具有檢測失敗之問題存在。 The conventional glass detection technology detects the glass with an autofocus laser detector. When using the two laser detectors, it will cause interference to each other and affect the accuracy of the detection. Therefore, only The surface of the glass and the cut of the section are inspected sequentially or in reverse order, thereby lengthening the overall inspection time. In addition, the laser detector may also be incapable of detecting the cut portion of the glass section because the thickness of the glass is too thin, and there is a problem that the detection fails.
此外，另一習知玻璃檢測技術，係以二鏡頭同時對玻璃之表面及斷面的切割處以連拍的方式進行檢測，惟當二鏡頭各自的焦點無法精準的位於一景深時，則會造成拍攝出的檢測影像具有模糊不清之問題，進而影響後續玻璃檢測準確性，而為了提升玻璃檢測準確性，則必須增加鏡頭拍攝的檢測影像數量，反而拉長整體的檢測時間。 In addition, another conventional glass detection technique uses a two-lens simultaneous detection of the surface of the glass and the cutting of the section in a continuous shooting manner, but when the respective focal points of the two lenses cannot be accurately located at a depth of field, The detected image is blurred, which affects the accuracy of subsequent glass detection. In order to improve the accuracy of glass detection, the number of detected images captured by the lens must be increased, and the overall detection time is extended.
有鑑於此，習知玻璃檢測技術確實仍有可以改良之必要。 In view of this, the conventional glass detection technology still has the need to be improved.
為解決上述問題，本發明係提供一種玻璃檢測系統及其方法，能夠縮短檢測時間，且同時對玻璃之表面及斷面的切割處進行檢測。 In order to solve the above problems, the present invention provides a glass detecting system and method thereof, which can shorten the detecting time and simultaneously detect the cut surface of the glass surface and the cross section.
