Glass film defect detection method, device and system

The invention relates to a glass film defect detection method, device and system. The glass film defect detection method comprises the following steps: based on a projectable film, obtaining a laser array penetrating through the surface of the film; the laser array at least comprises a column of linearly arranged lasers; receiving the laser penetrating through the surface of the film, and obtaining the intensity of the laser penetrating through the surface of the film; based on all the obtained intensities of the laser array, obtaining a judgment result of the film defect; wherein the judgment result of the film defect comprises an opaque flaw result, a hole result and an edge defect result; according to the glass film defect detection method, device and system, the process is simple, use is flexible, online nondestructive detection of the defects of the film is facilitated, the preparation cost is low, and the film is convenient to detect and verify while being processed. 本发明涉及一种玻璃薄膜缺陷检测方法、装置及其系统。该玻璃薄膜缺陷检测方法
