Description

Technical Field

[0001] The utility model relates to the technical field of film applicators, in particular to a side flip cover type dust-free film applicator. Background Art

[0002] The film applicator is an auxiliary tool used to apply tempered film to mobile phones and other devices more conveniently and accurately; it usually has the following features and functions: Precise positioning: helps ensure that the tempered film can be accurately attached to the screen to avoid problems such as crooked attachment or bubbles. Easy operation: makes the film application process relatively easy, even non-professionals can complete the film application well. Protective effect: during the film application process, it can protect the screen to a certain extent and prevent accidental scratches or damage; different types of film applicators may have different designs, but the purpose is to improve the efficiency and effect of film application.

[0003] An existing flip-top film applicator, i.e., a film applicator box, such as the film applicator tool and film applicator assembly described in the utility model patent authorization announcement number CN216509363U, adopts a film applicator box, which includes a base assembly and a face shell, and the base assembly includes a bottom shell and a positioning seat, and the face shell and the bottom shell are rotatably connected. This design can eliminate the trouble of assembling the base assembly and the face shell, and a snap connection is adopted on one side of the movable edge of the bottom shell and the face shell, so that the base assembly and the face shell can be fixedly covered. In addition, the inventor also proposed a dust-removing film applicator with a bracket and a dust-proof protective film described in the utility model patent authorization announcement number CN216103163U; similarly, a base and flip-top structure with a rotatable connection is disclosed;

[0004] The main purpose of this type of film applicator with a flip cover structure is to position the product to be filmed and the protective film on the base and the flip cover respectively, so that after the screen of the product to be filmed is cleaned, the protective film and the screen of the product to be filmed can be directly positioned and matched by closing the cover, thereby completing the film application operation more quickly and efficiently;

[0005] However, the existing film applicators are generally made of plastic materials, which will produce certain deformation. If this deformation is overcome by thickening the material, the cost of the film applicator will be increased. The film applicator made of plastic materials adopts a structure in which one side is flipped and the other side is positioned. There will be a certain tolerance at the rotation position, and the flip connection position of the film box is generally set on the short side, and the flip cover is prone to deformation, which may cause the protective film to slightly shift from the product to be applied. This slight shift is allowed for straight tempered films, but the inventors found that when this type of film applicator is applied to the auxiliary film of curved tempered films, since there will be a curved structure between the tempered film and the screen of the product to be applied, its slight position shift may cause inaccurate positioning of the curved surface, resulting in uneven local force between the attached curved tempered film and the product to be applied. After a little use, degumming will occur due to insufficient local force, resulting in bubbles between the curved tempered film and the screen of the product to be applied. In this regard, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0044] Taking the curved tempered film as an example, before leaving the factory, the corresponding curved tempered film will be attached to the upper protection sheet 30, and the drawstring 40 will be connected to the release film of the curved tempered film. The release film of the curved tempered film can also be set to be an integrated structure with the drawstring 40;

[0045] When in use, the screen 1 to be pasted is positioned on the base 10 through the positioning groove 11, and then the flip cover 20 is directly covered. The curved tempered film will be positioned above the screen 1 to be pasted, and the release film on the curved tempered film is torn off in reverse by pulling the pull tape 40 first. The pull tape 40 extends out of the base 10 and the flip cover 20 along the clearance hole 23. The user can pull the pull tape 40 after covering. The operation is convenient and simple. This operation method can tear off the release film during the gap fitting between the curved tempered film and the screen 1 to be pasted, thereby achieving a dust-free film tearing operation, so that there is basically no dust attached between the curved tempered film and the screen 1 to be pasted. After the film tearing is completed, the curved tempered film is pressed down with the help of the film pressing structure 22, so that the curved tempered film can be accurately attached to the screen 1 to be pasted.
