Description

Technical Field

[0001] The invention relates to the technical field of display screen production, in particular to a sealing device for an LCD liquid crystal display screen. Background Art

[0002] Liquid crystal display, abbreviated as LCD in English, is a type of flat display. The liquid crystal display uses a liquid crystal solution in two polarized materials, so that when the current passes through the liquid, the crystals are rearranged to achieve the purpose of imaging. When the LCD screen is produced, it needs to be sealed, so a corresponding LCD screen sealing device is needed. After searching, the Chinese patent publication number CN111013939A discloses a small piece of liquid crystal screen automatic sealing glue dispensing machine, including a base, a horizontal guide rail is installed on the base, a lifting guide rail is embedded vertically and movably in the horizontal guide rail, a longitudinal guide rail is embedded movably in the lifting guide rail, and a mounting seat is embedded movably at the bottom of the longitudinal guide rail, and a horizontal drive mechanism, a lifting mechanism and a longitudinal drive mechanism are installed on the horizontal guide rail, the lifting guide rail and the longitudinal guide rail respectively. This technical solution controls the three-dimensional multi-point automatic and precise glue dispensing of the glue dispensing machine through a servo control system. Although the glue dispensing efficiency is high, the display screen needs to be placed in the LCD screen fixing plate for fixing when in use, which is not only inconvenient to fix display screens of different sizes, but also requires repeated removal and placement operations, thereby reducing work efficiency.

[0003] The Chinese patent publication number CN221765876U discloses a sealing device for an LCD liquid crystal display screen. The utility model provides such a sealing device for an LCD liquid crystal display screen, including a placement plate, a mounting foot, a first slide rail, a motor, a screw, a first slider, a second slide rail, a second slider, a material guide frame and a material delivery pipe. A plurality of mounting feet are installed on the placement plate, a first slide rail is fixedly connected to the placement plate, and a motor is installed on the placement plate. This technical solution positions the material guide frame on a horizontal line by turning off the motor, stopping the movement of the first slider, and enabling the material guide frame to move smoothly. Although the LED sealing glue can be accurately applied to the LCD liquid crystal display screen, only one side of the display screen can be sealed at a time during use, resulting in low work efficiency. In addition, the display screen needs to slide on the placement plate, which is easy to cause wear on the surface of the display screen, thereby affecting the quality of the product.
