Abstract

The invention discloses a mobile phone curved glass typical defect online detection device and method. The online detection device comprises a work-piece transmission device, wherein the work-piece transmission device comprises a transmission guide rail, a plurality of transparent objective tables, a motion control card and a motor, and a rotating table; a plane part detection device, a curve edgedetection device and a R angle part detection device for forming three stations are orderly arranged along a transmission direction of the work-piece transmission device; the online detection methodperforms previous training learning on the background and scratch, burning, edge breakage, pit and like typical defect sample images through a convolutional neural network, and original images collected at three stations are divided into multiple sub-images consistent with the size of the training sample, the segmented sub-images are quickly identified, thereby judging whether the original imageshave defects or judging the defect variety. The scratch, burning, edge breakage, pit and like typical defect sample images can be online detected in real time, and the detection device has the features of being fast, efficient, precise and stable.

Description

technical field [0001] The invention relates to the field of automatic detection, in particular to an on-line detection device and method for typical defects of curved surface glass of mobile phones. Background technique [0002] In recent years, with the rapid development of Internet technology, smartphones, as the largest Internet terminal device, integrate Internet access, entertainment, and office work, and are favored by more and more consumers. While gradually improving functions and performance, major mobile phone manufacturers have begun to use curved glass with better texture and grip as mobile phone screens or mobile phone back shells. The glass back shell is good for the heat dissipation of the mobile phone, and will not inhibit the signal of the mobile phone, which is more conducive to the arrival of the 5G era and the realization of the wireless charging function. However, the use of curved glass design on mobile phones is still a bold attempt and innovation, b...
