Abstract
Description
Technical Field
[0001] The utility model relates to a film sticking jig, in particular to a jig for pulling out a release film without affecting the positioning of a protective sticker, thereby ensuring accurate sticking. Background Art
[0002] Nowadays, screen protectors for electronic devices such as smartphones, tablets, or laptops usually have a release film on their adhesive surface, and an adhesive layer between the screen protector and the release film. After the release film is torn off, the screen protector with the adhesive layer exposed can be pasted on the screen. Since the screen protector needs to be accurately aligned with the phone screen and the hole position when pasting the screen protector, the screen protector can be paired with an auxiliary film pasting jig to help users paste the screen protector by themselves. With the evolution of the design of the auxiliary film pasting jig, such as Figure 1 , Figure 2 As shown, the protective film 11 installed on the auxiliary film jig 10 has a release film 12 that is longer than the protective film 11, and the release film 12 includes a fitting portion 13, a turning portion 14, and an extension portion 15; the fitting portion 13 is bonded to the adhesive layer 111 of the protective film 11, the turning portion 14 is between the fitting portion 13 and the extension portion 15, the turning portion 14 is folded back and connected to the extension portion 15, so that the extension portion 15 overlaps with the fitting portion 13, and the extension portion 15 is longer than the protective film 11 and exposes the outer edge of the auxiliary film jig 10. When in use, the protective film 11 on the auxiliary film jig 10 is aligned with the screen 2 of the mobile phone 1, and the auxiliary film jig 10 is covered on the mobile phone 1, so that the edge of the mobile phone 1 is limited by the auxiliary film jig 10, and the protective film 11 is accurately corresponding to the screen 2, and the extension portion 15 is interposed between the screen 2 and the fitting portion 13, and the extension portion 15 protruding from the auxiliary film jig 10 is pulled, and the fitting portion 13 is bent, folded, pulled and gradually separated from the protective film 11, and the fitting portion 13 is folded and torn off to generate static electricity to remove dust on the screen, and at the same time, the protective film 11 is attached to the screen 2. However, since a reverse curvature arc 131 is generated when the bonding portion 13 is bent and folded, different qualities of the release film 12 will cause the reverse curvature arc 131 to have different curvature radii. The curvature radius of the reverse curvature arc 131 will lift up the auxiliary film fixture 10 combined with the protective film 11 to make it separate from the edge of the mobile phone 1. In this way, as the release film 12 is gradually pulled away and the reverse curvature arc 131 is moved away, the auxiliary film fixture 10 that falls down is prone to position deviation, causing the position of the protective film 11 to be skewed and inaccurate when it is bonded to the screen 2. The unstable bonding makes the exhaust unsatisfactory and generates bubbles, so it is difficult to be practical. Utility Model Content

[0019] The composition, function and effect of the above embodiment are described in detail as follows: Figures 3 to 5 As shown, the film fixture 20 of the present invention is made of, including but not limited to, plastic materials; the protective film 31 is made of, including but not limited to, scratch-resistant and wear-resistant tempered glass or plastic sheet materials; the release film 32 is a film sheet made of, including but not limited to, plastic materials, and the fitting portion 321, the turning portion 322 and the extension portion 323 are integrally formed or formed by bonding multiple pieces.
[0020] When the protective film 31 is to be attached to the screen 2 of the mobile phone 1, the upper cover plate 22, the positioning sheet 30, the protective film 31 and the release film 32 of the film attachment fixture 20 are first removed from the base 21 at the same time. The user then places the mobile phone 1 in the positioning space 23 of the base 21 with the screen 2 facing upward. In general, a camera lens 3 is protruding from the bottom of the mobile phone 1, and the lens hole 212 can provide a space for accommodating the camera lens 3. In this way, the mobile phone 1 can be placed horizontally in the positioning space 23. Next, the upper cover plate 22, the positioning sheet 30, the protective film 31 and the release film 32 are combined into one, and the cover positioning hole 222 of the upper cover plate 22 is fitted on the cover positioning column 213 of the base 21, so that the upper cover plate 22 is firmly covered and positioned on the base 21, and the protective film 31 is exactly corresponding to the top of the screen 2 of the mobile phone 1. The user then pulls the extension portion 323 of the outer edge of the film sticking fixture 20 with a finger. At this time, the sticking portion 321 is bent and folded from the turning portion 322 to be gradually separated from the protective film 31, and the sticking portion 321 is bent and folded to produce a reverse bending arc portion 324 (such as Figure 5 As shown in FIG. 2 , the curvature radius of the reverse curvature portion 324 can prop up the elastic movable plate 24, but the upper cover plate 22 can still be firmly positioned on the base 21. In other words, the position of the protective sticker 31 positioned on the upper cover plate 22 does not change, and the protective sticker 31 can still accurately correspond to the position of the screen 2. As the release film 32 is gradually pulled away, the reverse curvature portion 324 gradually moves away from the front end of the protective sticker 31. The protective sticker 31 will use the reverse curvature portion 324 as a fulcrum to make its front end fall close to the screen 2 of the mobile phone 1. At the same time, the elastic movable plate 24 held up by the reverse curved portion 324 elastically returns to its original shape as the reverse curved portion 324 moves away. In this way, the protective sticker 31 is elastically pressed by the elastic movable plate 24 to adhere to the screen 2 from the front end. When the release film 32 is completely pulled away from the protective sticker 31 and begins to diffuse and adhere to other parts of the screen 2 and cover the protective sticker 31, the protective sticker 31 can be accurately adhered to the screen 2, thereby achieving the effect of precise fitting and easy gas discharge without easily generating bubbles.
[0021] It is worth mentioning that after the film sticking jig 20 is pasted, the protective film 31 is no longer available on the upper cover 22. The utility model allows users to purchase the integrated upper cover 22, positioning sheet 30, protective film 31 and release film 32 for replacement. In this way, the base 21 of the utility model can be reused, thereby saving resources, reducing waste and protecting the earth's environment.
[0022] The above-described embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in the technical field on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the claims.
