Description

Technical Field

[0001] The utility model relates to the technical field of tempered films, in particular to a UV tempered film for assisting in absorbing edge overflow glue. Background Art

[0002] With the development of mobile phone screens towards micro-curved screen structures, in order to bring a better user experience, the prior art uses UV tempered films to solve the problem that traditional tempered films cannot be fully attached to micro-curved screen mobile phones. The UV tempered film utilizes post-curing UV glue. First, the UV glue is attached to the mobile phone screen, and then through a tempered film of corresponding size, the UV glue completely penetrates between the tempered film and the mobile phone screen in a covering manner. Finally, a specially equipped UV lamp is used for baking and curing the glue to complete the operation of attaching the tempered film to the mobile phone screen. This method solves to a certain extent the problems of poor adhesion, air bubbles and loose adhesion of traditional tempered films, because the UV glue can fill the gap between the tempered film and the mobile phone screen when in a liquid state. However, if the existing UV tempered film does not use a corresponding auxiliary film applicator during the attachment process, there will be a serious problem of overflow glue. The UV glue will overflow from the edge of the tempered film and then penetrate into the side of the mobile phone, hindering the structures such as buttons or holes on the side of the mobile phone. This not only affects the appearance of the mobile phone, but in severe cases, it will also cause damage to the buttons or holes, making the mobile phone unable to be used normally.

[0003] Therefore, how to solve the problem of overflow glue during the attachment of the existing UV tempered film has become an urgent technical problem to be solved, so as to ensure that the purpose of restricting the overflow of UV glue can be achieved without using an auxiliary film applicator, thus not affecting the normal function and appearance of the mobile phone.

[0023] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , in the embodiment of the present utility model, a UV tempered film for assisting in absorbing edge overflow glue includes a curved tempered film main body 10 and a release film 20 attached to the curved tempered film main body 10. The periphery of the curved tempered film main body 10 is a curved surface structure that bends downward. Glue-absorbing strips 30 are attached to the peripheries of the release film 20, and the glue-absorbing strips 30 extend beyond the edge of the release film 20 and are lower than the lower end of the curved tempered film main body 10. When in use, the UV glue is attached to the mobile phone screen, and the curved tempered film main body 10 is positioned to cover the mobile phone screen. Since the glue-absorbing strips 30 attached to the peripheries of the release film 20 extend beyond the edge of the release film 20 and are lower than the lower end of the curved tempered film main body 10, when the UV glue is in a liquid state and gradually completely penetrates between the curved tempered film main body 10 and the mobile phone screen, some of the UV glue will overflow from its edge, and the glue-absorbing strips 30 can timely absorb the about-to-overflow UV glue, thereby preventing the UV glue from overflowing from the edge of the curved tempered film main body 10 and then penetrating into the side of the mobile phone.

[0025] With this setting, the problem of glue overflow during the bonding process of the existing UV tempered film can be effectively solved, ensuring that the purpose of restricting the overflow of UV glue can be achieved without using an auxiliary film applicator, avoiding the obstruction of the structure such as the side buttons or holes of the mobile phone caused by glue overflow, and thus ensuring that the normal functions of the mobile phone are not affected; this operation no longer requires the assistance of an auxiliary film applicator, simplifies the film application operation process, improves the convenience and efficiency of film application, enables users to complete the film application process more easily, and enhances the user experience. In addition, it can also make the UV tempered film more stable and reliable during the attachment process, reduce the risk of film application failure caused by glue overflow, improve the practicality and applicability of the UV tempered film, and meet the needs of users for high-quality mobile phone films.

[0026] Please refer to Figure 5 , in the embodiment of the present invention, it is further proposed that double-sided tapes 40 are respectively attached to the periphery of the release film 20, and the glue absorption strip 30 is attached to the double-sided tape 40. The glue absorption strip 30 is firmly attached to the periphery of the release film 20 through the double-sided tape 40. During the film application process, even affected by the flowing impact of the liquid UV glue and possible external slight touches, etc., it can maintain a stable position, ensuring that it can accurately and timely absorb the UV glue that is about to overflow, effectively preventing the glue overflow problem caused by the displacement of the glue absorption strip 30, and further improving the stability and reliability of the film application process.

[0027] Please refer to Figure 5 , in the embodiment of the present invention, it is further proposed that the cross-section of the glue absorption strip 30 is a flat structure with a curvature, which can adapt to the curved surface structure formed by the edge of the release film 20 due to the curved tempered film main body 10, thus ensuring the firm attachment of the glue absorption strip 30. The lower edge of the glue absorption strip 30 is spaced apart from the curved tempered film main body 10 through the double-sided tape 40 and the release film 20. During film application, the distance of this interval can prevent the glue absorption strip 30 from deforming to the position between the curved tempered film main body 10 and the mobile phone screen, thereby preventing the absorption of the UV glue that bonds the edge of the curved tempered film to the mobile phone screen, and avoiding the problem of gaps existing between the edge of the curved tempered film main body 10 and the mobile phone screen.

[0028] Please refer to Figures 1-3, in the embodiment of the present utility model, it is further proposed that there are four glue-absorbing strips 30, and the four glue-absorbing strips 30 are distributed on the four sides of the release film 20, and adjacent two glue-absorbing strips 30 are arranged at intervals. The release film 20 is provided with a tear-off part 50 at the position of the interval between adjacent two glue-absorbing strips 30. Generally, there are no structures such as buttons or holes at the corner positions of the mobile phone. Therefore, the glue-absorbing strip 30 is not provided at this position, and the tear-off part 50 is further extended, which is convenient for tearing off the release film 20 and the glue-absorbing strip 30 after the curved tempered glass film is cured and adhered to the mobile phone screen with UV glue. Among them, an adhesive patch 60 is also attached to the lower end of the tear-off part 50, and a release sheet 70 is attached to the lower part of the adhesive patch 60. The tear-off part 50 can be attached to the side of the mobile phone through the adhesive patch 60, so as to achieve the purpose of positioning the main body 10 of the curved tempered glass film. During operation, first tear off the release sheets 70 on the two tear-off parts 50 on one side of the release film 20, and then position the position between the main body 10 of the curved tempered glass film and the mobile phone screen by attaching the adhesive patch 60 to the side of the mobile phone. After positioning, turn over the main body 10 of the curved tempered glass film from the mobile phone screen along the side of the attached adhesive patch 60. After turning it over, drop the UV glue, and finally turn the main body 10 of the curved tempered glass film over again to cover the mobile phone screen, so that the UV glue can perform operations such as penetration and curing. Until the UV glue is cured, tear off the release film 20 by pinching the two tear-off parts 50 on the other side to complete the film pasting operation of the main body 10 of the curved tempered glass film. Therefore, by providing the adhesive patch 60 at the lower end of the tear-off part 50 and attaching the tear-off part 50 to the side of the mobile phone through the adhesive patch 60, the position between the main body 10 of the curved tempered glass film and the mobile phone screen can be accurately positioned. This design avoids repeated adjustments caused by inaccurate positions during the film pasting process, improves the efficiency and accuracy of film pasting, and ensures a more perfect fit after film pasting. In addition, the tear-off part 50 has a transition section 51 and an expansion section 52 that expands and extends along the end of the transition section 51, and the adhesive patch 60 is attached to the lower end of the expansion section 52.

[0029] In the embodiment of the present utility model, it is further proposed that the glue-absorbing strip 30 is made of a hard water-absorbing cotton material. Making the glue-absorbing strip 30 of a hard water-absorbing cotton material, the hard water-absorbing cotton has good water absorption and glue absorption properties; during the bonding process of the UV tempered glass film, it can quickly absorb the about-to-spill UV glue and effectively prevent the problem of glue overflow; its Shore hardness is preferably between 40 degrees and 60 degrees, which not only ensures a certain hardness, can maintain a stable shape during the film pasting process and will not easily deform, ensuring the accuracy of the glue-absorbing position; but also has a certain softness, can better fit the release film 20 and the edge of the mobile phone screen, and fully play the role of glue absorption.

[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
