Description

Technical Field

[0001] The invention relates to the field of mobile phone film pasting, and in particular to an auxiliary film pasting tool and an auxiliary film pasting method. Background Art

[0002] When a mobile phone screen is scratched or broken, the cost of replacing it is often hundreds or even thousands of yuan, so people have developed mobile phone protective films to be applied to the mobile phone screen to protect the screen from scratches. When applying the film to the mobile phone, the protective film needs to be aligned with the mobile phone screen, and during the application process, it is necessary to ensure that there are no bubbles between the protective film and the screen, otherwise it will affect the vision and the protective film will easily fall off. Therefore, it is difficult for inexperienced users to apply the film by themselves, and usually they seek professional help to apply the film, which not only wastes time but also costs labor costs, which brings inconvenience to consumers.

[0003] For this purpose, the inventor has invented an integrated film applicator and has applied for a Chinese patent with the application number 201920498593.7. This integrated film applicator includes a frame for accommodating and fixing a mobile phone, the frame having a first end corresponding to the mobile phone screen and a second end corresponding to the back of the mobile phone, the first end having an inward convex plate at the periphery, the convex plates forming a protective film accommodating space, the top of the convex plate forming a film fixing portion, and the protective film is fixed in cooperation with the adhesive portion on the protective sheet of the protective film (referred to as a patch in this application), and the thickness of the convex plate matches the thickness of the film body. The protective film accommodating space on the integrated film applicator is an open space. When the mounting is unsuccessful, the film body can be removed from the screen, fixed back to the protective film accommodating space on the integrated film applicator by a patch, and then the film can be applied again, that is, the film can be applied repeatedly conveniently. However, because the patch is a very thin soft film with an adhesive layer, it is difficult to manually align the adhesive portion around the patch with the film applicator so that the patch is supported on the top of the protective film accommodating space. For this reason, the inventor further designed an auxiliary film applicator tool. Summary of the invention

DETAILED DESCRIPTION

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] The auxiliary film sticking tool involved in this application is used to assist in completing the protective film 60 (see Fig.12 ) and film applicator 50 (see Fig.12 ) assembly.

[0037] Please refer to Figure 1 , Figure 2 The auxiliary film pasting tool includes a substrate 10 and a patch positioning ring 20. The top of the substrate 10 has a receiving cavity 12 for accommodating the film pasting device 50, and an annular groove structure 11 with an opening facing upward is arranged around the bottom edge of the receiving cavity 12. The patch positioning ring 20 is movably installed in the annular groove structure 11, and an elastic member 30 is arranged at the bottom of the patch positioning ring 20. When there is no external force, the top of the patch positioning ring 20 protrudes from the bottom of the receiving cavity 12 and extends into the receiving cavity 12 (such as Figure 2 When the patch positioning ring 20 is subjected to pressure, the top of the patch positioning ring 20 retracts into the annular groove structure 11 (as shown in FIG. Fig. 9 status shown).

[0038] The elastic member 30 can be made of silicone, metal spring, spring, etc.

[0039] As a preferred embodiment, the elastic member 30 is a plurality of springs, and a plurality of blind holes 13 are arranged at intervals at the bottom of the annular groove structure 11 (see Figure 1 ), one end of the plurality of springs is fixed in the plurality of blind holes 13, and the other end of the plurality of springs abuts against the bottom of the patch positioning ring 20. Using multiple springs as the elastic member 30 and distributing them at equal intervals, on the one hand, has better elasticity, and on the other hand, facilitates the smoother movement of the patch positioning ring 20. However, the disadvantage is that the installation is more troublesome due to the small size of the spring. It is also possible to use a silicone column instead of a spring, but the elasticity is relatively poor.

[0040] The patch in the present application is used as a connector to connect the protective film 60 and the film applicator 50 .

[0041] Figure 3 and Figure 4 A structure of a patch 40 is shown. Figure 3 , Figure 4 The patch 40 includes a film attachment area 42 for attaching a protective film and a bonding portion 41 arranged around the film attachment area 42 for bonding a film applicator. The bonding portion 41 and the film attachment area 42 are provided with a first adhesive layer 44. The first adhesive layer 44 is covered with a release layer 45. The release layer 45 is used to protect the first adhesive layer 44. The release layer 45 needs to be removed before use.

[0042] Further, the release layer 45 includes a first release sheet 452 and a second release sheet 451, wherein the first release sheet 452 is opposite to the film attachment area 42, and the second release sheet 451 is opposite to the bonding portion 41. In this way, the second release sheet 451 can be removed first to assemble the patch 40 with the film applicator 50, and then the first release sheet 452 can be removed to assemble the protective film 60. This can prevent the film attachment area 42 from sticking to the film applicator 50 or a person's hand when assembling the patch 40 with the film applicator 50.

[0043] In order to further facilitate film application, it is preferred that the adhesive force of the first adhesive layer 44 is smaller than the adhesive force of the adhesive layer on the protective film 60 .

[0044] like Figure 3 As shown, a lug 43 is further provided on one side of the patch 40. The lug 43 is provided for hand grasping, so as to facilitate the separation of the patch 40 from the film applicator 50 and the protective film 60 after assembly.

[0045] Figure 5 The structure of a film applicator 50 is shown in FIG. Figure 5 The film applicator 50 includes a frame 51 for accommodating and fixing the mobile phone, wherein the frame 51 has a first end corresponding to the mobile phone screen and a second end corresponding to the back of the mobile phone. Figure 5 The first end is the upper end, the second end is the lower end, the first end has an inward convex plate 53 on its periphery, the convex plates 53 form a protective film accommodating space 54, the top of the convex plate 53 forms a patch fixing portion, and cooperates with the adhesive portion 41 on the patch 40 to fix the patch 40 to the top of the protective film accommodating space 54 (such as Fig.10 The thickness of the convex plate 53 matches the thickness of the protective film 60 to ensure that the protective film 60 is bonded to the patch 40 (as shown in FIG. Fig.12 As shown in the figure, the bottom of the protective film 60 is in the same plane as the bottom of the convex plate 53, so that after the mobile phone is placed in the mobile phone accommodating cavity 55, the protective film 60 is attached to the screen.

[0046] like Figure 5As shown, the top of the convex plate 53 is lower than the top of the frame 51, forming a step 52, so that the patch 40 is fixed to the film applicator 50 (as shown in FIG. Fig.10 As shown in the figure, the top of the frame 51 is flush with or slightly lower than the top of the frame 51. In this way, the patch 40 will not be lifted by mistake.

[0047] Combine the following Figures 6 to 12 Describe the method of using the above-mentioned tools to assist in film application.

[0048] First, remove the second release sheet 451 on the patch 40, and install the patch 40 into the accommodating cavity 12 on the auxiliary film-applying tool with the help of the patch positioning ring 20. Specifically, Figure 6 As shown, one end of the patch 40 is pressed against the inner side of the patch positioning ring 20 and the patch 40 is slowly placed into the accommodating cavity 12 on the film sticking tool. Figure 7 As shown, this can ensure that the position of the patch 40 is accurate.

[0049] Next, if Figure 8 As shown, the film applicator 50 is placed into the accommodating cavity 12 with the top facing downward, and the film applicator 50 is pressed downward. The film applicator 50 pushes the patch positioning ring 20 to move downward and retract into the annular groove structure 11. The top of the convex plate 53 on the film applicator 50 ( Fig. 9 The lower part in the middle) is bonded to the bonding portion 41 on the patch 40, such as Fig. 9 As shown, at this time, the elastic member 30 is compressed and stores energy.

[0050] Then take out the film applicator 50, as shown in FIG. Fig.10 As shown in FIG. 1 , the patch 40 has been installed on the film applicator 50. Then, the first release sheet 452 on the patch 40 is removed. Then, the protective film 60 is installed into the protective film receiving space 54 on the film applicator 50. Fig.11 As shown, one end of the protective film 60 is pressed against the side wall of the protective film accommodating space 54 (i.e., the inner end of the convex plate 53), and the protective film 60 is slowly placed into the protective film accommodating space 54, and the protective film 60 is bonded to the patch 40, as shown in FIG. Fig.12 As shown, the assembly of the protective film 60 and the film applicator 50 is now completed.

[0051] It can be seen that, with the aid of the auxiliary film sticking tool, the patch 40 can be quickly and easily supported on the top of the protective film accommodating space 54 on the film sticking device 50, so that the assembly of the protective film 60 and the film sticking device 50 is simple and convenient.
