[0002] Tempered glass is a common protective film that can increase the hardness and wear resistance of the LCD screen to prevent scratches and damage.

[0003] The existing LCD screen tempered film coating device usually requires the LCD screen to be placed in the operating area first, and the LCD screen is limited, and then the tempered film is attached to the surface of the LCD screen to complete the coating operation. However, the existing device requires the operator to tear off the protective layer on the tempered film in advance, thereby exposing the colloid on the tempered film, which is more troublesome to operate.
