Description

Technical Field

[0001] The utility model relates to the film sticking field technology, in particular to a film sticking device. Background Art

[0002] Almost everyone has an electronic device (such as mobile phones, tablets, and watches). The screens of electronic devices are easily scratched during use, and because the service life of electronic devices is relatively long, it is not cost-effective to replace the screens of electronic devices many times after the screens are scratched. Therefore, protective films that are much cheaper than electronic device screens have become essential accessories for users. Now a certain number of consumers prefer to purchase protective film components and apply the protective films themselves, but in the previous film application solutions, after the release film of the protective film component is pulled open, the protective film as a whole will contact the screen of the electronic device. Due to operational reasons or the uneven placement of the electronic device, after the protective film as a whole contacts the screen of the electronic device, some parts will not be fully in contact and bubbles will be formed, resulting in film application failure, and the film needs to be reapplied. The protective film generally needs to be applied once, and it cannot be used again after it is peeled off.

[0003] For this reason, various film pasting devices are now available on the market, which can well complete the film pasting of electronic devices. The main structure of these film pasting devices usually includes a pasting aid and a protective film assembly; the pasting aid has a positioning cavity for positioning the electronic device; the protective film assembly is arranged in the positioning cavity. When pasting the film, the electronic device is placed in the positioning cavity, and after alignment, the release film of the protective film assembly is torn off and pulled out, so that the adhesive surface of the protective film of the protective film assembly fits the screen surface of the electronic device.

[0004] In the prior art, in order to allow the gas between the protective film and the electronic device screen to be discharged during film application, a pre-pressing elastic member is usually provided on the film application aid to play a pre-pressing role during film application. Since the film application aid is usually an injection molded part, and the injection molded part is prone to deformation and unevenness, when the pre-pressing elastic member is attached to the film application aid, the pre-pressing elastic member will also be uneven. Therefore, when the pre-pressing elastic member is pressed, the pre-pressing force will be uneven, resulting in irregular exhaust and affecting the quality of film application. Therefore, it is necessary to improve the current film application device. Utility Model Content

[0005] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a film pasting device, which can effectively solve the problem of uneven exhaust when pasting films in the prior art film pasting devices.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A film pasting device includes an assisting pasting device and a protective film assembly; the assisting pasting device has a positioning cavity for positioning an electronic device; the protective film assembly is arranged in the positioning cavity, and a pre-pressing elastic member is fixedly attached to one side of the protective film assembly facing the inner bottom surface of the positioning cavity.

[0008] As a preferred solution, the pre-pressing elastic member is located at the middle position of the protective film assembly and extends horizontally or longitudinally.

[0009] As a preferred solution, the pre-pressing elastic member is located at one end position in the longitudinal direction of the protective film assembly and extends horizontally.

[0010] As a preferred solution, the protective film assembly includes a protective film, a release film, and a positioning film.

The release film has a pulling part that extends out of the assisting pasting device from the end; the positioning film is fixedly attached to the other side of the protective film, and one end of the positioning film cooperates with the assisting pasting device for positioning.

[0011] As a preferred solution, the pre-pressing elastic member is fixedly attached to the side of the positioning film facing away from the protective film.

[0012] As a preferred solution, an avoidance position is provided on the positioning film, and the pre-pressing elastic member is located in the avoidance position and is fixedly attached to the protective film.

[0013] As a preferred solution, the inner bottom surface of the positioning cavity is a fully enclosed surface, or a window is opened on the bottom plate of the film pasting device. The window communicates with the positioning cavity. The setting of the window facilitates the user to observe the extrusion and bubble discharge conditions. The pre-pressing elastic member is arranged in a dislocation manner with the window.

[0014] As a preferred solution, there is one window, and the window is located at one end position in the longitudinal direction of the assisting pasting device, or extends from one end to the other end in the longitudinal direction of the assisting pasting device, facilitating the user to observe the extrusion and bubble discharge conditions.

[0040] Please refer to Figures 1 to 13 as shown, which shows the specific structure of the preferred embodiment of the present utility model, including an applicator 10 and a protective film assembly 20.

[0041] The applicator 10 has a positioning cavity 101 for positioning the electronic device 30. The applicator 10 can have various structural forms: such as Figure 5 as shown, the bottom plate of the applicator 10 can be fully enclosed, that is to say, the inner bottom surface of the positioning cavity 101 is a fully enclosed surface. As Figures 6 to 8 as shown, a window 102 can be opened on the bottom plate of the applicator 10. Specifically: as Figure 6 as shown, there can be one window 102, which extends from one longitudinal end of the applicator 10 to the other longitudinal end, and the window 102 is rectangular, facilitating the user to observe the extrusion and bubble discharge conditions. As Figure 7 as shown, the window 102 is located at one longitudinal end position of the applicator 10, and the window 102 is square, facilitating the user to observe the extrusion and bubble discharge conditions. As Figure 8 as shown, there can be two windows 102, and the two windows 102 are separated from each other and are respectively located at the two longitudinal end positions of the applicator 10, facilitating the user to observe the extrusion and bubble discharge conditions. And, the applicator 10 can be an integrally injection-molded structure. Of course, as Figure 9 as shown, the applicator 10 is an applicator in the form of a packaging shell, which can include an upper shell 11 and a lower shell 12 that are spliced up and down. The positioning cavity 101 is located on the lower shell 12, and the upper shell 11 and the lower shell 12 form a packaging shell to better save costs.

[0042] The protective film assembly 20 is disposed in the positioning cavity 101. A pre-pressing elastic member 40 is fixedly attached to the protective film assembly 20. When the protective film assembly 20 is disposed on the applicator 10, the elastic pre-pressing member 40 is disposed offset from the window 102 on the applicator 10 so that the bottom plate of the applicator 10 presses against the pre-pressing elastic member 40. The pre-pressing elastic member 40 faces the inner bottom surface of the positioning cavity 101 (i.e., the inner bottom surface of the bottom plate). Since the protective film assembly 20 is flat, it can effectively ensure the flatness of the pre-pressing elastic member 40. And when pressing, even if the applicator 10 is not flat, the pre-pressing elastic member 40, being a foam, can absorb a part of the unevenness and exhaust air more regularly, thereby ensuring the uniformity of film application.

[0043] Specifically, the protective film assembly 20 includes a protective film 21, a release film 22, and a positioning film 23. The release film 22 is fixedly attached to one side of the protective film 21. The release film 22 has a pulling portion 201 that extends out of the applicator 10 from the end of the upper shell 11. During use, the release film 22 is pulled out by pulling the pulling portion, so that the release film 22 is separated from the protective film 21 to facilitate better film application. One side of the positioning film 23 is fixedly attached to the other side of the protective film 21. One end of the positioning film 23 cooperates with the applicator 10 for positioning, so that the protective film 21 is accurately placed in the positioning cavity 101. The pre-pressing elastic member 40 is fixedly attached to the side of the positioning film 23 facing away from the release film 22. Of course, an avoidance position (not shown in the figure) may be provided on the positioning film 23, and the pre-pressing elastic member 40 is placed in the avoidance position and fixedly attached to the protective film 21, which is not limited thereto.

[0044] In addition, the pre-pressing elastic member 40 can be arranged in various ways. For example, Figure 10 as shown, the pre-pressing elastic member 40 can be located at the middle position of the protective film assembly 20 and extend longitudinally. As Figure 11 shown, the pre-pressing elastic member 40 can be located at the middle position of the protective film assembly 20 and extend transversely. As Figure 12 shown, the pre-pressing elastic member 40 can be located at one end position in the longitudinal direction of the protective film assembly 20 and extend transversely. As Figure 13 shown, the pre-pressing elastic member 40 can also be located at the other end position in the longitudinal direction of the protective film assembly 20 and extend transversely. The setting position of the pre-pressing elastic member 40 is not limited. Different setting positions of the pre-pressing elastic member 40 can achieve different exhaust effects. In addition, the pre-pressing elastic member 40 is strip-shaped, and the pre-pressing elastic member 40 is made of foam material, which is not limited thereto.

[0045] The usage method of this embodiment is described in detail as follows:

[0046] In the initial state, the protective film assembly 20 and the preloading elastic member 40 are located in the positioning cavity 101. The preloading elastic member 40 is fixedly attached to the protective film assembly 20 and contacts the inner bottom surface of the positioning cavity 101. When applying the film, the screen of the electronic device 30 is placed downward so that the electronic device 30 is placed into the positioning cavity 101. After alignment, by pulling the pulling part 201 outward, the release film 22 is torn and pulled out, so that the adhesive surface of the protective film 21 is attached to the screen surface of the electronic device 30. Then, by pressing the electronic device 30 or the film applicator 10, the air bubbles appearing between the protective film 21 and the screen surface are squeezed and eliminated by the preloading elastic member 40.

[0047] The design focus of the present utility model is that by fixedly attaching the preloading elastic member to the protective film assembly, since the protective film assembly is flat, the flatness of the preloading elastic member can be effectively ensured. And when pressing, even if the film applicator is not flat, the preloading elastic member can absorb a part of the unevenness, realizing more regular exhaust, thereby ensuring the uniformity of film application and greatly improving the film application quality of the electronic device.

[0048] The technical principle of the present utility model has been described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present utility model and cannot be construed in any way as a limitation on the protection scope of the present utility model. Based on the explanations herein, those skilled in the art can think of other specific embodiments of the present utility model without creative labor, and these embodiments will fall within the protection scope of the present utility model.
