Glass color detection device and method

Abstract

The invention discloses a glass color detection device and method. According to the device, an image acquisition device is fixed on a first supporting frame, a mounting box is rectangular and providedwith an opening, the mounting box is fixed to a second supporting frame, a light source is fixed above the mounting box and the image acquisition device, the output end of the image acquisition device is connected with the input end of the image processing system, and the image processing system is used for obtaining an R value, a G value and a B value of a picture acquired by the image acquisition device. During detection, the glass is cut into glass with the same size; the inner wall of the mounting box is set as a white background; then the glass is inserted into the mounting box in a front-back fit mode in the thickness direction, and the glass is photographed by the image acquisition device; and then the R value, the G value and the B value are obtained and respectively compared withset standards, if the R value, the G value and the B value are greater than or equal to the numerical standards, the glass meets color requirements, and if at least one numerical value is less than the numerical standard, the glass does not meet the color requirements.

Description

technical field [0001] The invention belongs to the technical field of cover glass detection, in particular to a glass color detection device and method. Background technique [0002] In the era of continuous innovation of touch display technology, cover glass is widely used as a screen protection material for electronic products with touch and display functions. It has high light transmittance and strong scratch resistance, and has gradually become a An indispensable raw material for mobile terminal electronic products such as tablets and touch notebooks. In the production process of cover glass, the inspection items of cover glass are constantly being established and improved, and the color inspection item of cover glass is an important item for monitoring product quality. Cover glass generally does not allow color fluctuations. [0003] At present, there are two main ways to detect the color of the cover glass. The first method is carried out by visual inspection.

Problems solved by technology

[0003] At present, there are two main ways to detect the color of the cover glass. The first method is carried out by visual inspection. Since there are many factors that affect visual observation, such as the color of the personnel themselves Perceptual differences, ability experience, emotions, observation environment, etc., cause large differences in glass color observation results, rough test results, poor accuracy, and cannot really play a role in monitoring product color quality

The other is to use special instruments for detection. Due to the high economic cost of professional instruments, especially for enterprises with multiple production lines and large demand, the economic cost is too high
