Anti-interference screen appearance optical detection device and detection method

Abstract

The invention relates to an anti-interference screen appearance optical detection device and a detection method, which belong to the technical field of screen detection. The anti-interference screen appearance optical detection device comprises a frame body, a linear light source, an image acquisition part and an annular light source, wherein the linear light source is connected to the frame body,and the irradiation end of the linear light source faces the screen; the image acquisition part is connected to the frame body, the image acquisition part is located vertically above the linear lightsource, and the acquisition end of the image acquisition part faces vertically downwards; and the annular light source is connected to the frame body, and the output end of the annular light source faces the screen. According to the anti-interference screen appearance optical detection device, detection interference of dust can be removed, whether a screen has defects or not can be accurately detected, and meanwhile, the detection accuracy and the working efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of screen detection, and in particular relates to an anti-jamming screen appearance optical detection device and detection method. Background technique [0002] The screen is a high-precision optical component. After the screen is produced, the appearance of the screen needs to be inspected to avoid problems such as display defects. [0003] At present, the traditional detection method is to use manual preliminary identification under LED lights to determine the type and location of defects, and at the same time, manual re-inspection is required for re-judgment. [0004] However, due to the limitations of the physical conditions of the human eye and the subjectivity of human emotions, it is difficult to achieve high standards in terms of speed and accuracy, and it is difficult to guarantee accuracy. Moreover, manual inspection takes a long time, and it is difficult to improve work efficiency. This has caus...

[0003] At present, the traditional detection method is to use manual preliminary identification under the LED light to determine the type and location of the defect, and at the same time, manual re-inspection is required for re-judgment

[0004] However, due to the limitations of the physical conditions of the human eye and the subjectivity of human emotions, it is difficult to achieve high standards in terms of speed and accuracy, and it is difficult to guarantee accuracy.

Moreover, manual inspection takes a long time, and it is difficult to improve work efficiency.

This leads to problems such as low accuracy and low work efficiency.

[0005] In addition, during the screen appearance inspection, due to the insufficient cleanliness of the workshop, there is inevitably some dust on the inspection site, which will interfere with the inspection results and seriously affect the inspection of the screen appearance.
