step two: then the adjusting component (212) drives the third gear (213) to rotate, the third gear (213) is matched with the fourth gear (214) to drive the second lead screw (215) to rotate, the second lead screw (215) drives the two connecting blocks (216) to move oppositely, the two connecting blocks (216) drive the two positioning components (217) to move oppositely, the distance between the two positioning components (217) is adjusted to be matched with the width of the LCD screen, then the positioning components (217) drive the positioning plates (218) to move horizontally, and then the four positioning plates (218) position two sides of the LCD screen to complete the fixation of the LCD screen;
step three: the method comprises the following steps that a subsequent LCD screen is placed on a conveying belt (102), a conveying assembly (103) drives a conveying roller (101) to rotate, the conveying roller (101) drives the conveying belt (102) to rotate, the subsequent LCD screen is conveyed to the position below a first LCD screen, the subsequent LCD screen is fixed on a fixing device in sequence by repeating the first step and the second step, a plurality of LCD screens are fixed in sequence from top to bottom, when the position of the LCD screen needs to be adjusted in the horizontal direction, two rotating frames (225) move to the two sides of the corresponding LCD screen, an adjusting belt (227) on each rotating frame (225) is in contact with the side edge of the LCD screen, then a positioning plate (218) cancels contact with the side edge of the LCD screen, an adjusting assembly (228) drives an adjusting wheel (226) to rotate, the two adjusting wheels (226) drive an adjusting belt (227) to rotate, the adjusting belt (227) drives the LCD screen to move in the horizontal direction, when the position of the LCD screen needs to be adjusted in the longitudinal direction, a rotating assembly (223) drives a lateral moving assembly (224) to rotate 90 degrees, and then the adjusting belt (227) drives the adjusting belt (225) to move the side edge of the LCD screen to contact with the side edge of the LCD screen, and the LCD screen, the adjusting belt (225), and the adjusting belt (225) does not contact with the side edge of the LCD screen, and the adjusting belt (225) to adjust the LCD screen, and the adjusting belt (225);
step four: during detection, the lifting assembly (201) drives the first gear (202) to rotate, the first gear (202) is matched with the second gear (203) to drive the first lead screw (204) to rotate, the first lead screw (204) drives the two adjusting blocks (205) to move oppositely, the adjusting blocks (205) are matched with the rotary rod (206) to jack up the lifting blocks (207), the lifting blocks (207) drive the lifting frame (208) to ascend, the lifting frame (208) drives the LCD to ascend through the turnover frame (210), the turnover assembly (209) drives the turnover frame (210) to overturn, further drives the LCD to overturn, the angle of the LCD is adjusted, after the detection of the LCD at the top is completed, the lifting frame (208) descends to an initial position, the two rotary frames (225) move to the two sides of the LCD at the top, then the adjusting belts (227) on the rotary frames (225) are in contact with the sides of the LCD, the adjusting belts (227) drive the LCD to move in the horizontal direction, the corresponding positioning plates (218) cancel the clamping of the LCD at the top, the LCD at the top is conveyed out of the LCD horizontally, and the LCD below can be detected.
