Online detection device for glass screens

Abstract

The invention discloses an online detection device for glass screens. The online detection device comprises a roller conveying device, a square enclosing frame, an adjustable beam frame, a plurality of high-frequency line scanning cameras, an A-seam light-emitting stroboscopic lamp, a B-seam light-emitting stroboscopic lamp, a pattern recognition system and a controller, wherein the roller conveying device is erected on a rectangular frame-shaped chassis; the square enclosing frame is erected above the roller conveying device by a side bracket; the adjustable beam frame is erected at the top surface of the enclosing frame; the high-frequency line scanning cameras are connected with the adjustable beam frame and are distributed in a linear array; the A-seam light-emitting stroboscopic lamp and the B-seam light-emitting stroboscopic lamp are distributed and erected between the whole bottom surface of the high-frequency line scanning camera array and the whole top surface of the roller conveying device at interval from front to rear; the pattern-signal output end of the high-frequency line scanning cameras is connected with the input end of the pattern recognition system; and the whole focusing line of the high-frequency line scanning camera array, the light-gathering line of the A-seam light-emitting stroboscopic lamp and the light-gathering line of the B-seam light-emitting stroboscopic lamp are converged into a light-gathering alignment line. The online detection device disclosed by the invention has the advantages of high automation degree, high detection efficiency and more objective and comprehensive grating.

Description

technical field [0001] The invention belongs to the technical field of detection and relates to an online detection device for a glass screen. Background technique [0002] The glass screens used in displays, etc. need to be inspected to determine whether there are cracks, bubbles, sundries and other defects inside. In traditional technology, visual inspection is generally carried out manually in the assembly line with the help of optical instruments, etc., and the product is graded according to the visual inspection. Grading and replaying, but the efficiency of manual detection is low, the workload is heavy and it is easy to miss detection, there will inevitably be subjective bias in the rating, and the use effect is not ideal. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an on-line inspection device for glass screens with a high degree of automation, high detection efficiency, relatively more ob...
