System and method for online automatically detecting defects on glass surface of touch screen

Abstract

The invention discloses a system and a method for online automatically detecting defects on a glass surface of a touch screen. The system comprises a driving part, an imaging part and a screening part, wherein the driving part is used for sending touch screen glass to the imaging part; the imaging part is used for detecting if the glass surface of the touch screen has defects; the screening part is used for removing the touch screen glass having defects; the driving part comprises three driving units; the three driving units are fixedly connected with a bottom fixing plate; each driving unit comprises a bottom fixing plate, a servo motor, a driving shaft, a magnetic transmission gear driving wheel, a magnetic transmission gear driven wheel and a driven shaft; and the imaging part and the screening part are respectively arranged on the middle and last driving units. The system provided by the invention has the advantages of high detection precision, high efficiency and capability of quantitative recognition. Non-contact magnetic gear pairs serve as the driving media, so that the system provided by the invention has non-contact, noiseless, vibration-free and pollution-free characteristics and are fit for the detection process for the touch screen glass in a dust-free environment.

Description

technical field [0001] The invention belongs to the field of machine vision detection, and relates to an online automatic detection system and method for glass surface defects of a touch screen. Background technique [0002] Touch screen glass components are widely used in various production fields of the national economy, in daily work and public life, such as display screens, mobile phone panels, ipads, various industrial and household glass panels, etc. When there are scratches, chipping and other defects on the surface of the glass component panel of the touch screen, it will greatly affect the functional quality index and aesthetics of the product. The assembly line operation in industrial production is very important for improving the quality of products and realizing the transformation and upgrading of enterprises. [0003] The traditional detection method for touch screen glass components is mainly the visual method. Workers place the surface of the touch screen gla...

AI Technical Summary

Problems solved by technology

The visual method is greatly affected by the proficiency of the inspected person and is highly subjective, and long-term inspection will cause human eye fatigue, resulting in misjudgment and missed inspection of defects

At the same time, the detection speed of the visual method is slow, the missed detection rate is high, and the reliability is poor. There is no way to realize the assembly line detection of the entire production process.

A large number of workers need to be recruited and trained, and the labor cost is high, which is contrary to the country's national policy of developing labor-intensive industries into technological innovation
