Description

Technical Field

[0001] The utility model relates to the technical field of display screen processing devices, in particular to a display screen film pasting device. Background Art

[0002] In today's electronic devices, display screens are key components for information output, and their quality and performance directly impact the user experience. Widely used in a variety of electronic products, including mobile phones, computers, and televisions, these displays offer high resolution and excellent color reproduction, providing users with clear, vivid images and text.

[0003] In order to protect the display screen from scratches, wear and fingerprints, a protective film is usually applied to its surface. This protective film can not only effectively extend the service life of the display screen, but also maintain its good display effect.

[0004] However, the traditional film laminating machines used in the display screen application process have numerous drawbacks. Due to the lack of an effective tensioning mechanism, the protective film is prone to wrinkling during the application process, which results in partial overlap of the film when the pressure rollers are applying the film. This overlap not only affects the flatness and aesthetics of the film, but can also lead to uneven adhesion, thereby reducing the film's protective effect and service life. Furthermore, traditional film laminating machines can experience unstable clamping when clamping the display screen, affecting the precision and quality of the film application. To address these issues, the present utility model provides a novel display screen laminating device. Utility Model Content

[0027] The working principle of the display screen film laminating device of the present invention is as follows: The display screen film laminating device realizes accurate and efficient film laminating on the display screen through the coordinated action of various components. First, the base is adjusted to a horizontal state through the leveling mechanism to ensure a smooth film laminating process, the display screen to be laminating is placed in the groove of the display screen placement platform, and is stably clamped by the clamping component. Then, the protective film is placed on the display screen, and the lifting mechanism adjusts the height of the carrier plate so that the film pressing roller assembly contacts the protective film and presses the protective film tightly against the display screen. At the same time, the film tensioning mechanism presses the tensioning rod downward through the spring so that the universal ball contacts and tensions the protective film to avoid wrinkles on the protective film. The horizontal driving mechanism drives the film pressing roller assembly to move in the horizontal direction, thereby evenly pressing the protective film against the display screen. The film tensioning mechanism is located in front of the movement of the film pressing roller assembly, flattening the protective film in advance to prevent wrinkles and overlaps.

[0028] In this embodiment, as a preferred technical solution, the clamping assembly includes an adjusting bolt 12 threadedly connected to the inner wall of the groove 3, and the adjusting bolt 12 extends into the groove 3 and is rotatably provided with a clamping plate 13 at one end, and a guide rod 14 is fixed on the side of the clamping plate 13. The guide rod 14 passes through the groove 3 and is slidably connected to the groove 3, and a rubber pad 15 is fixed on the side of the clamping plate 13 that contacts the display screen.
