Description

Technical Field

[0001] The utility model relates to the field of liquid crystal display screen fixing equipment, in particular to a liquid crystal display screen fixing mechanism. Background Art

[0002] At present, after the production of existing LCD screens is completed, they are generally tested again before installation to avoid affecting the quality of the LCD screen after installation, which may cause the product to need to be reworked or scrapped. Existing testing equipment generally requires the LCD screen to be positioned by a fixture before testing. However, although the fixture can position the LCD screen, it cannot fix the LCD screen, causing the LCD screen to shake or vibrate in the positioning groove due to the operation of the table or equipment, causing damage to the LCD screen, which seriously affects the testing effect, quality and efficiency of the LCD screen.

[0003] The Chinese utility model patent with announcement number CN212905799U, announced on April 6, 2021, discloses a fixture for adsorbing and fixing a liquid crystal display screen. The invention adsorbs and fixes the liquid crystal display screen in the display screen positioning groove through air holes to reduce the shaking of the liquid crystal display screen in the display screen positioning groove. However, in the invention, the liquid crystal display screen still needs to be manually prevented from being in the display screen positioning groove, and the liquid crystal display screen needs to be manually removed after inspection, and the degree of intelligence is relatively low.
