The flipping mechanism 5 includes two fixed plates 51, a protective sleeve 52, a flipping motor 53, a gear 54, two rotating rollers 55, and a gear ring 56.

[0022] The working principle of this LCD display manufacturing device will be explained in detail below.

[0023] like Figure 1-5 As shown, in the LCD display manufacturing process, the device is first connected to an external power source. Based on the size of the LCD display, the control panel 9 starts the stepper motor 81. The output shaft of the stepper motor 81 drives the lead screw 82 to rotate, first securing the left end of the LCD display into the left U-shaped clamp 64. Then, the moving block 83 moves the right U-shaped clamp 64 horizontally to the left, causing the right U-shaped clamp 64 to engage at the edge of the LCD display, ensuring the edge of the LCD display is tightly against the chassis with multiple upper and lower connection holes 652. Finally, the control panel 9 starts the vacuum pump 61, utilizing vacuum... Pump 61 draws air from the connection hole 652, creating an internal negative pressure, which in turn creates a pressure difference with the external atmospheric pressure. The suction force generated by this pressure difference can firmly adhere to the surface of the LCD screen, thus facilitating the installation of electronic components such as glass sheets onto the LCD screen substrate. When installing the LCD screen, the flip motor 53 can be started via the control panel 9. The output shaft of the flip motor 53 drives the gear 54 to rotate, and in conjunction with the gear ring 56, the rectangular frame 3 is rotated 180 degrees via the rotating roller 55 through gear transmission, further facilitating the installation of the screen on the LCD screen.
