Abstract

The invention relates to the field of detection of a backlight screen and particularly relates to visual inspection equipment of the backlight screen. The visual inspection equipment comprises a conveying device and further comprises a first detection unit, a film tearing device and a second detection unit; the first detection unit, the film tearing device and the second detection unit are arranged beside the conveying device; each of the first detection unit and the second detection unit comprises an intelligent lightening device and a camera. Compared with the prior art, the visual inspection equipment of the backlight screen has high detection speed and high detection efficiency and is unlikely to interfere by the outer environment; and the possibility of missed detection and wrong detection is low, the stability is good, manual detection can be replaced and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of backlight screen detection, in particular to a backlight screen visual detection device. Background technique [0002] Display screens have been widely used in mobile communications, smart homes, automotive instruments, and industrial equipment. In the display screen, the light source for the display screen is the backlight screen located at the bottom of the display screen. The quality of the backlight screen directly determines the quality of the display screen. quality. Therefore, the quality inspection link of the backlight screen is extremely critical in its production process. [0003] At present, manufacturers of backlight screens all use manual inspection methods for the quality inspection of backlight screen products, and there are many problems in manual inspection. First, the number of products is huge, and the light source of the backlight screen is turned on and off for a long time, which will cause ...
