[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, a film pasting device for liquid crystal display production is proposed in this embodiment, including a rectangular frame 2, a triangular seat 3 and a bottom plate 13, the rectangular frame 2 is placed above the bottom plate 13, the rectangular frame 2 and the bottom plate 13 are fixedly connected to one side of the triangular seat 3, a space for placing the display screen 1 is reserved between the rectangular frame 2 and the triangular seat 3, and the side of the triangular seat 3 facing the display screen 1 is a horizontal plane 14; when pasting the film, the dust on the surface of the display screen 1 is cleaned in advance, and then water is sprayed on the surface of the display screen 1 to ensure that the film and the display screen 1 are firmly adsorbed, and after the initial attachment is completed, the triangular seat 3 is pressed against both sides of the display screen 1, and the two ends of the display screen 1 are inserted between the rectangular frame 2 and the bottom plate 13.

[0020] A guide plate 4 is provided inside the rectangular frame 2, and both ends of the guide plate 4 are fixedly connected to the rectangular frame 2. The guide plate 4 is perpendicular to the horizontal plane 14. A slider 5 is sleeved outside the guide plate 4, and the slider 5 is slidably connected to the guide plate 4. A scraper 10 for removing bubbles on the surface of the display screen 1 is provided below the slider 5, and a lifting member is provided between the scraper 10 and the slider 5. The scraper 10 is controlled to fall by the lifting member, and the scraper 10 will contact the surface of the display screen 1, and the slider 5 will be pulled toward the triangular seat 3. When the slider 5 slides along the guide plate 4, the scraper 10 will also scrape along the surface of the display screen 1 to both sides of the display screen 1, and quickly squeeze out the bubble liquid between the protective film and the display screen 1, thereby ensuring the quality of the film, saving time and effort.

[0021] In order to prevent the protective film from being scratched due to excessive force when the scraper 10 slides on the surface of the display screen 1, a roller groove 16 is provided at the lower end of the scraper 10, and a rubber roller 17 is installed in the roller groove 16. Both ends of the rubber roller 17 are fixedly connected to the groove wall of the roller groove 16. The rubber roller 17 is arranged at the lower end of the scraper 10, and can contact the protective film on the display screen 1 one step before the scraper 10 falls. The rubber roller 17 is retractable, and can effectively scrape away the bubbles and liquid between the protective film and the display screen 1 without damaging the protective film.

[0022] About the lifting member: The lifting member includes a grip plate 9, which is fixedly connected to the lower end of the slider 5. Adjustment blocks 11 are provided at both ends of the grip plate 9. Adjustment bolts 12 are mounted on the adjustment blocks 11. The adjustment bolts 12 pass through the adjustment blocks 11 and are fixedly connected to the upper end of the scraper 10. The height of the scraper 10 is controlled by the adjustment bolts 12. When scraping the bubbles between the protective film and the display screen 1, the adjustment bolts 12 at both ends of the grip plate 9 are rotated at the same time. When the adjustment bolts 12 are screwed downward, the scraper 10 is pushed so that the scraper 10 contacts the film material on the display screen 1. The height of the scraper 10 is conveniently controlled.

[0023] It should be noted that the distance between the two adjusting blocks 11 is greater than the length of the diagonal of the rectangular frame 2. In this way, when the adjusting block 11 is pulled, the adjusting bolt 12 assembled on the adjusting block 11 will not conflict with the corner of the rectangular frame 2.

[0024] In order to prevent the display screen 1 from deflecting between the rectangular frame 2 and the bottom plate 13, which would affect the attachment of the protective film, two positioning seats 6 are provided at one end of the rectangular frame 2 away from the triangular seat 3. The two positioning seats 6 are fixedly connected to the two sides of the rectangular frame 2. A tension bolt 7 is mounted on the positioning seat 6. The tension bolt 7 passes through the positioning seat 6 and is rotatably connected to a rubber pressure cap 8 provided below the positioning seat 6. The tension bolt 7 is threadedly connected to the positioning seat 6. When attaching the film, the display screen 1 is attached to one side of the triangular seat 3, the tension bolt 7 is rotated, and the tension bolt 7 is screwed downward. The rubber pressure cap 8 connected to the lower end of the tension bolt 7 will fall and contact the display screen 1, and the rubber pressure cap 8 fixes the display screen 1. The use of the rubber pressure cap 8 as a limiter can ensure that the display screen 1 is stable when attaching the film, and will not cause damage to the display screen 1.

[0025] In the preferred embodiment, a rubber pad 15 is provided on the upper end of the bottom plate 13, and a plurality of dot-shaped protrusions are arranged on the surface of the rubber pad 15. The rubber pad 15 provided on the upper end of the bottom plate 13 can play an anti-slip role, improve the stability of the display screen 1 when applying the film, and protect the display screen 1.

[0026] Working principle: When applying the film, clean the dust on the surface of the display screen 1 in advance, then spray water on the surface of the display screen 1 to ensure that the film and the display screen 1 are firmly adsorbed. After completing the initial attachment, place the triangular seat 3 against the two sides of the display screen 1, and insert the two ends of the display screen 1 between the rectangular frame 2 and the bottom plate 13. Turn the tension bolt 7 and screw the tension bolt 7 downward. The rubber pressure cap 8 connected to the lower end of the tension bolt 7 will fall and contact the display screen 1, and the rubber pressure cap 8 will fix the display screen 1. At the same time, turn the adjustment bolts 12 at both ends of the grip plate 9. When the adjustment bolts 12 are screwed downward, the scraper 10 will be pushed to make the scraper 10 contact the film material on the display screen 1. Pull the slider 5 toward the triangular seat 3. When the slider 5 slides along the guide plate 4, the scraper 10 will also scrape along the surface of the display screen 1 to the two sides of the display screen 1, and quickly squeeze out the bubble liquid between the protective film and the display screen 1. The strength of the scraper 10 is adjustable, which is easy to operate and saves manpower and material resources.
