Backlight AOI automatic detection system based on LCD display screen

Abstract

The invention provides a backlight AOI automatic detection system based on an LCD display screen, and belongs to the technical field of LCD display screen detection. The backlight AOI automatic detection system based on the LCD display screen comprises a conveying assembly and a detection assembly. The cleaning roller is started to clean dust on the LCD display screen backlight module, so that the situation that the rear-section detection misinformation is caused by foreign matters is prevented, the jacking part falls off, detection is performed through the optical detection part, pictures are recorded, an alarm is given if the pictures are not good, the LCD display screen backlight module falls off, and the LCD display screen backlight module is transferred to the non-finished product translation part; and unqualified products are transferred to the side conveyor through the unqualified product translation piece, and qualified products are continuously transferred through the main conveyor, so that the problems that dust needs to be manually cleaned and the overall detection efficiency and the productivity are relatively low in LCD screen backlight AOI automatic detection in related technologies are effectively improved.

Description

technical field [0001] The invention relates to the field of LCD display screen detection, in particular to an AOI automatic detection system based on the LCD display screen backlight. Background technique [0002] The LCD display itself does not emit light, which requires the backlight module to provide a light source, so the quality of the backlight directly affects the look and feel of the display. Bright spots, foreign objects, scratches, dark spots, and white shadows often appear during the production process of the backlight. At present, the LCD display module production line is constantly expanding and upgrading, and the requirements for work efficiency are getting higher and higher, the quality requirements for products are also getting higher and higher, and there are higher requirements for backlight, more High brightness, uniformity, and some subtle defects that are difficult to detect with the naked eye need to be detected by modern scientific instruments instead...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the above deficiencies, the present invention provides an AOI automatic detection system based on LCD display backlight, which aims to improve the problems in the related art that the automatic detection of LCD display backlight AOI requires manual cleaning of dust and the overall detection efficiency and production capacity are low.
