[0015] The present invention provides a liquid crystal screen conveying device with an anti-deviating function. It has the following beneficial effects:

[0016] (1) This invention uses a motor to drive the roller to rotate, and the roller drives the reciprocating screw to rotate. The reciprocating screw rotates to push the clamp to position the LCD screen, thereby preventing the LCD screen from shifting and affecting subsequent processing, thereby ensuring production efficiency. When the bracket moves, it will drive the air cylinder to move. The movement of the air cylinder will squeeze the movable rod, and the air in the air cylinder will be sprayed out through the nozzle, which can clean the dust on the conveyor belt and prevent the dust from sticking to the LCD screen, thereby improving the protection of the LCD screen. After the B clamp contacts the LCD screen, the LCD screen will push the B clamp. The movement of the B clamp will drive the impact rod to move. The movement of the impact rod will hit the nozzle. After the nozzle is hit, the nozzle will vibrate, so that the nozzle can spray to more areas, further improving the protection effect.

[0017] (2) In the present invention, the LCD screen contacts the push plate B, which is pushed to drive the push rod to move. The movement of the push rod will push one end of the alignment rod to move. After one end of the alignment rod is pushed, the support rod rotates and the other end of the alignment rod moves toward the LCD screen. When the LCD screen is placed vertically on the conveyor belt, it will be pushed by the alignment rod to rotate the LCD screen horizontally. This prevents the LCD screen from being placed vertically on the conveyor belt and affecting subsequent processing, thereby ensuring production efficiency.

[0018] (3) The invention connects an electrostatic brush to a positioning rod so that the electrostatic brush can sweep away static electricity on the LCD screen, thereby preventing static electricity from damaging electrical components in the LCD screen and improving the protection effect on the LCD screen. The LCD screen contacts the push plate B, which drives the push rod to move. The movement of the push rod squeezes the liquid in the hydraulic cylinder to move. The squeezed liquid pushes the hydraulic rod to move. The movement of the hydraulic rod drives the gear to rotate. The rotation of the gear pushes the conductive rod to move. The movement of the conductive rod contacts the positioning rod, and the static electricity on the electrostatic brush is released by grounding the conductive rod. This prevents the LCD screen from rotating and rubbing against the conveyor belt to generate static electricity when the LCD screen is corrected, thereby further improving the protection effect on the LCD screen.
