[0002] Liquid crystal display, or "LCD" for short, is a flat-panel display device that uses the optical properties of liquid crystal materials to change under the action of an electric field to display images. It was introduced in the late 1970s and can be divided into three categories: twisted nematic, super twisted nematic, and color film. Liquid crystal displays have the advantages of pure flat-panel display, low power consumption, and no radiation. They are widely used in the display field of electronic equipment such as computers, televisions, and oscilloscopes. The principle is to use electric current to stimulate liquid crystal molecules to generate points, lines, and surfaces in conjunction with the back light tube to form a picture.

[0003] In the prior art, a cutting device for LCD display production with patent announcement number CN214081559U is disclosed. The above patent delivers the display to the bottom of the cutting machine through a conveyor and a feeding shaft. At the same time, an electric push rod pushes a fixed suction cup to be placed on the display to prevent the display from shifting during cutting. The display is cut while being fixed. However, the following deficiencies still exist in actual use: from a practical point of view, the device can only be fixed by adsorption of the suction cup, and the display can be prevented from shifting during cutting. The fixing stability is not enough, and the position of the display can only be judged manually, which has a certain error.

The shaft 601, the slider 602 and the fixed plate 603 threadedly connected to the outer surface of the driving shaft 601 will move relatively, thereby fixing the LCD display screen in the middle position of the upper end of the base 1, so as to facilitate the subsequent cutting, and limit the position of the LCD display screen during cutting, thereby improving the practicality of the anti-deviated cutting device for LCD display screen production, and through the fixed handle 606, the rotation of the driving shaft 601 is facilitated, and through the rubber pad 604, not only can the friction force be increased to facilitate the movement of the LCD display screen, but also it has a certain protection and buffering effect.

[0026] This solution has the following working process: first, the LCD display screen is slowly passed through the rotating shaft 401 and the rolling shaft 701, and the cutting position of the LCD display screen is exactly located at the upper end of the cutting blade 5, and then the symmetrical active shaft 601 is rotated, and the symmetrical slider 602 and the fixed plate 603 threadedly connected to the outer surface of the symmetrical active shaft 601 will move relatively, thereby fixing the LCD display screen, and at the same time, the spring 404 of the limiting device 4 squeezes the rotating shaft 401, and the rotating shaft 401 squeezes the upper end of the LCD display screen, and the rolling shaft 701 of the rolling device 7 squeezes the lower end of the LCD display screen, so that the LCD display screen is fixed to a certain extent, but has a certain elasticity, and then the servo motor 2 is turned on, and the output end of the servo motor 2 drives the cutting blade 5 to cut.
