Description

Technical Field

[0001] The utility model relates to the technical field of backlight-free liquid crystal screen detection, in particular to a backlight-free liquid crystal screen rapid detection device. Background Art

[0002] A non-backlit LCD screen is an LCD screen that can display images without a backlight source. It usually uses reflective or transmissive technology to utilize the ambient light to display images without the need for an additional backlight source. This type of LCD screen can display clear images outdoors and in well-lit environments, and it saves power. Non-backlit LCD screens are often used in some e-book readers and small display screen devices. There are at least the following disadvantages in the existing non-backlit LCD screen detection process: the existing non-backlit LCD screens are often manually handheld with a strong flashlight, and then the non-backlit LCD screen is illuminated, and then the non-backlit LCD screen fault is detected by manually observing whether there is a signal image display. The detection process is cumbersome, and it is not convenient to perform batch detection of non-backlit LCD screens, which affects the detection efficiency. Therefore, we have introduced a non-backlit LCD screen rapid detection device. Utility Model Content

The conveyor belt 51 is located below the camera 64 and the strong light source 63. The card slot 54 can limit the LCD screen to prevent the LCD screen from shaking and displacing during transportation.

[0026] It should be noted that the utility model is a fast detection device for a non-backlit LCD screen. During use, the motor 4 is started by an external control system to start running, driving the active shaft 41 to rotate, and the active shaft 41 works in conjunction with the driven shaft 8 to drive the conveyor belt 51 to rotate. The conveyor belt 51 places the LCD screen to be detected on the No. 2 lifting piece 53 and the No. 1 lifting piece 52.

When the LCD screen moves to the lower part of the camera 64 and the strong light source 63, the strong light source 63 is started. The strong light source 63 will emit strong light to illuminate the LCD screen. The camera 64 will record the irradiated area, and the camera 64 will transmit the captured image signal to the display screen 7, so that the inspector can clearly see the irradiated position and image of the LCD screen on the display screen 7. The display screen 7 is the output device of the system. It will display the image captured by the camera 64 in real time. The inspector can judge whether the display screen has a display signal by checking whether the display screen has a display signal. After the inspection is completed, the inspector can start the motor 4 again through the external control system to make the conveyor belt 51 continue to rotate, thereby driving the next LCD screen into the inspection area, making the entire inspection process faster and more efficient.
