Description

Technical Field

[0001] The utility model relates to the technical field of display screen cutting, in particular to a liquid crystal display screen cutting device. Background Art

[0002] A liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces that cooperate with the back light tubes to form a picture. In the LCD screen production process, a whole large screen substrate is usually cut into several LCD screens of preset sizes. Since the LCD screen is a brittle material, the reliability of the LCD screen cutting device is required to be high during the cutting process.

[0003] The prior art discloses a device for cutting the edge of a liquid crystal display screen with the publication number of cN218969098U. In view of the existing method, the liquid crystal screen needs to be manually clamped each time it is cut, and manual adjustment is also required when the liquid crystal screen needs to be cut, which is inconvenient in production. There is no structure on the device to collect dust during the cutting process, which easily causes dust splashing. The following scheme is now proposed, which includes a workbench, a moving rod and a cutting plate. A fixing and cutting mechanism and a collecting component are arranged on the device, so that the liquid crystal screen is clamped during the cutting process, ensuring that the liquid crystal screen is not easy to move during the processing process, reducing material loss, and allowing the device to adapt to the cutting of liquid crystal screens of different sizes, ensuring that the device is more practical, and no manual adjustment is required, which greatly facilitates the cutting process, saves time, and can ensure the cleanliness of the workshop and the personal safety of the workers.

[0004] However, the cutting assembly of the above-mentioned LCD screen cutting device can only move horizontally during cutting, and cannot be adjusted forward and backward or in other directions, resulting in the device being able to cut at only a certain angle, poor adaptability, and poor effect during use, which needs to be improved.
