[0026] Both the feeding conveying structure and the discharging conveying structure include a conveying roller group 8 arranged on the large frame 1, and both the feeding conveying structure and the discharging conveying structure include a conveying guide rail 9 arranged on the large frame 1, the conveying guide rail 9 is arranged along the X-axis direction, and a conveying frame that can move along the X-axis direction is arranged on the conveying guide rail 9, and a conveying frame is provided with a conveying lifting cylinder, and the piston part of the conveying lifting cylinder is provided with a U-shaped conveying fork 10 that can be lifted and lowered therewith, and the opening of the U-shaped conveying fork 10 is arranged toward the friction platform 14, and a group of conveying suction cups 11 are arranged at the front ends of the two arms of the U-shaped conveying fork 10; the width of the U-shaped conveying fork 10 is smaller than the spacing between the conveying roller group 8 and the discharging conveying roller group.

By adjusting the angle of the wool wheel positioning frame 5, the angle of the friction wool wheel 15 relative to the glass is achieved, thereby adjusting the friction orientation angle of the glass.

[0029] Working principle: After the LCD glass to be oriented by friction is transported to the designated position by the conveying roller group 8 in the feeding conveying structure, the position can be located by the sensing device; if steering is required, the glass turntable 12 rises, and the turntable suction cup 13 on it absorbs the LCD glass and rises to the top of the conveying roller group 8, and then the glass turntable 12 drives the LCD glass on it to rotate to the set angle, and the U-shaped conveying fork in the feeding and handling structure rises, and the conveying suction cup 11 on it absorbs the LCD glass on the conveying roller group 8 and runs to the top of the conveying roller group 8, and then the conveying frame moves in the X-axis direction to the top of the friction platform 14 through the conveying guide rail 9; the feeding and handling is completed;

[0030] After the feeding and handling is completed, the friction suction cup 4 on the friction platform 14 rises to absorb the glass on the U-shaped handling fork 10, and then the U-shaped handling fork 10 returns to its original position, and then the friction suction cup 4 descends until the LCD glass is flat on the friction platform 14; after the friction platform 14 detects that the LCD glass is in place, the friction platform 14 moves along the friction guide rail 2, and starts to rub when it contacts the friction wool wheel 15; at the beginning of the work, the direction and height of the friction wool wheel 15 can be adjusted to adjust the pressing amount and the friction direction; after the LCD glass on the friction platform 14 is completely rubbed, it will be separated from the friction wool wheel 15 in the discharge direction; the friction orientation of the glass is completed;
