A guiding device for sticking LCD protective film

Abstract

The invention discloses a guiding device for laminating a liquid crystal screen protective film, which includes a processing table, a translation groove is opened on the top of the processing table, and the inner wall of the translation groove is rotatably connected with two horizontal rail bars set in parallel, wherein The surface of a horizontal rail rod is provided with a screw part, the left side of the processing table is fixedly installed with a stepping motor, and the output end of the stepping motor is fixedly connected with the screw part, and the threaded part is installed on the screw part. U-shaped adjustment seat. The guiding device for pasting the protective film of the LCD screen, if the protective film of the LCD screen is pulled during the winding process, the sliding frequency of the sealing magnetic plug in the limit chute will decrease, and then the limit chute will move toward the magnetic movement groove per unit time. The air intake volume inside is much smaller than the outflow volume of the exhaust pipe per unit time, and the conductive slide plate is in contact with the two conductive blocks a, so that the pulling of the LCD screen protective film is released, and the LCD screen protective film returns to normal winding State, to ensure the yield and quality of the LCD screen protective film.

Description

technical field [0001] The invention relates to the technical field of liquid crystal screen lamination, in particular to a guiding device for laminating a liquid crystal screen protective film. Background technique [0002] The liquid crystal screen is based on the liquid crystal material as the basic component. The liquid crystal material is filled between two parallel plates, and the arrangement of the molecules inside the liquid crystal material is changed by voltage, so as to achieve the purpose of shading and transmitting light to display different shades and staggered Consistent images, and as long as a three-color filter layer is added between the two flat plates, a color image can be displayed. [0003] After the LCD screen is produced, it needs to be covered with a protective film on its surface, and the LCD screen protective film needs to be rolled and stored before being pasted on the LCD screen. The finished product of the screen protective film has a poor effe...

Problems solved by technology

[0003] After the production of the LCD screen is completed, a protective film needs to be pasted on its surface, and the LCD screen protective film needs to be rolled and stored before being pasted on the LCD screen. The winding effect of the screen protective film is poor, and the LCD screen protective film is easy to be damaged during winding
