If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0043] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0044] Reference Figure 1 , Figure 4 , Figure 5 and Fig. 9 As shown, a film sticking device 1000 of an embodiment of the present invention is used to assist manual application of a film to the screen of an electronic device 2000 (such as a mobile phone, a tablet, etc.). It is understandable that the film sticking device 1000 of this embodiment can be used to apply a film to the back panel of the electronic device 2000 in addition to applying a film to the screen of the electronic device 2000, and is not specifically limited here.

[0045] Reference Figure 1 and Figure 2 As shown, a film sticking device 1000 of an embodiment of the present invention includes a mounting frame 100, a protective film 200 and a positioning structure 300. The mounting frame 100 includes a panel 110 and a panel 120, and the panel 120 is connected to the outer periphery of the panel 110. It should be noted that the panel 120 can be configured to be connected to the entire outer periphery of the panel 110, or to be connected to a portion of the outer periphery of the panel 110. For example, the panel 120 includes a plurality of sections of plate bodies respectively connected to the outer periphery of the panel 110, and the plurality of sections of plate bodies are arranged at intervals. The panel 110 and the panel 120 form a positioning cavity (not shown in the figure) of the mounting frame 100, and the positioning cavity is open at one end away from the panel 110, for the electronic device 2000 to be loaded into the positioning cavity and positioned in the positioning cavity. The positioning of the electronic device 2000 is mainly achieved by the panel 120 and the side wall of the electronic device 2000.

[0046] Reference Figure 2As shown, the panel 110 is provided with a mounting groove 111 communicating with the positioning cavity, and the mounting groove 111 can be arranged to extend along the length direction or the width direction of the mounting frame 100. The protective film 200 is located in the positioning cavity, and the positioning structure 300 is positioned and connected with the protective film 200 through the mounting groove 111, so that the protective film 200 is positioned on the mounting frame 100. In order to ensure the stability of the connection between the positioning structure 300 and the protective film 200, the protective film 200 is overlapped with at least part of the mounting groove 111.

[0047] It is understandable that after the mounting frame 100 and the electronic device 2000 are positioned, the protective film 200 and the screen of the electronic device 2000 can be accurately aligned, thereby improving the accuracy of the film application of the electronic device 2000. The positioning structure 300 is detachably connected to the panel 110, and the positioning structure 300 can be arranged on the outer wall of the mounting frame 100 or in the mounting groove 111, so as to facilitate disassembly. After the user disassembles the positioning structure 300 from the panel 110, the protective film 200 can be separated from the mounting frame 100, so that the protective film 200 is released on the screen of the electronic device 2000. Moreover, the user can press the protective film 200 through the mounting groove 111 to attach the protective film 200 to the screen of the electronic device 2000, which is simple to operate and improves the quality and efficiency of film application.

[0048] As another embodiment, the protective film 200 may not use the positioning structure 300, so as to be positioned on the panel 110 or the enclosure 120, or positioned on the panel 110 and the enclosure 120 at the same time. For example, the protective film 200 may be fixed to the inner side of the panel 110 (the side facing the positioning cavity) by bonding, or a groove for positioning is provided on the panel 110, or a groove for positioning is provided on the enclosure 120, and the structure is positioned on the panel 110 or the enclosure 120 by means of snap connection or the like. It should be noted that in the film pasting device 1000 of this embodiment, the user presses the protective film 200 through the mounting groove 111 to attach the protective film 200 to the screen of the electronic device 2000 and separate it from the mounting frame 100, so that the protective film 200 is released from the screen of the electronic device 2000, which is simple to operate and improves the quality and efficiency of film pasting. Therefore, the film pasting device 1000 of this embodiment can also achieve precise alignment between the screen of the electronic device 2000 and the protective film 200 during the film pasting process.

[0049] In addition, the positioning method of the protective film 200 may also be a combination of the above-mentioned various embodiments, or a combination of two of the embodiments, which is not specifically limited here.

[0050] Reference Figure 1 and Figure 2As shown, the film sticking device 1000 of the embodiment of the present invention further includes a scraper card 400. The scraper card 400 may be a sheet structure, a bent structure or a block structure. The scraper card 400 is detachably connected to the mounting frame 100. It is understood that the scraper card 400 may be connected to the mounting frame 100 by bonding, clamping, etc. Moreover, the scraper card 400 may be combined with the mounting frame 100 as an integral structure, or may be arranged on the outer wall of the mounting frame 100. The scraper card 400 is used to assist in pushing the protective film 200 to be attached to the screen of the electronic device 2000, and / or to remove the bubbles or air edges between the protective film 200 and the screen of the electronic device 2000. After the user attaches the protective film 200 to the electronic device 2000 and separates the mounting frame 100 from the electronic device 2000, the bubbles or air edges between the protective film 200 and the screen of the electronic device 2000 may be removed by pushing the scraper card 400, which makes the operation more convenient and efficient, reduces the difficulty of sticking the film, further improves the quality of sticking the film, and enhances the user's operating experience.

[0051] It can be understood that the panel 110 is provided with a first notch 112, and the first notch 112 is formed on the outer periphery of the panel 110, which can be understood as being formed by cutting a portion of the outer periphery of the panel 110 inward. The first notch 112 can be connected to the mounting groove 111 or not. The first notch 112 is located at one end of the panel 110 along the length direction or the width direction of the mounting frame 100. The scraper card 400 is adapted to the shape of the first notch 112, and the scraper card 400 can be detachably installed in the first notch 112, that is, installed at one end of the length direction or the width direction of the mounting frame 100, which is more convenient to use. The scraper card 400 and the mounting frame 100 form an integrated structure, making the appearance of the film-applying device 1000 more beautiful. Moreover, the design of the first notch 112 facilitates the user to separate the mounting frame 100 from the electronic device 2000, thereby improving the film-applying efficiency and reducing the wear of the mounting frame 100 on the electronic device 2000.

[0052] Reference Figure 2 and Figure 3As shown, it can be understood that the scraper card 400 is tightly connected with the first notch 112, so that the installation frame 100 can ensure the accuracy when used to position the electronic device 2000. The scraper card 400 is installed in the first notch 112, which can save materials and reduce the production cost of the film sticking device 100 while ensuring the function of the installation frame 100. It is also convenient to fix the scraper card 400 to the installation frame 100, and it is also convenient to package the scraper card 400 and the installation frame 100. For example, when the scraper card 400 and the installation frame 100 can be made into a structure similar to a knock-out hole in the production process, so that when the installation frame 100 is used to position the electronic device 2000, the connection between the scraper card 400 and the installation frame 100 is stable, and the scraper card 400 is also easy to separate from the installation frame 100 when in use. In addition, the first notch 112 is provided in the installation frame 100 to facilitate the separation of the installation frame 100 from the electronic device 2000, thereby improving the efficiency of film sticking.

[0053] It is understandable that the protective film 200 generally includes a film with glue adhered to one side, a release layer attached to the adhesive surface of the film, and a protective layer attached to the other side of the film. The protective film 200 may also include only the film and the release layer. Therefore, the positioning structure 300 is generally connected to the protective layer or the film, and the connection method may be a method such as bonding that is convenient for users to separate. The film application operation of the film application device 1000 of this embodiment may include the following steps:

[0054] Step 1: Clean the screen of the electronic device 2000;

[0055] Step 2: Remove the release layer;

[0056] Step 3: Insert the film sticking device 1000 into the electronic device 2000;

[0057] Step 4: Remove the positioning structure 300 from the installation frame 100;

[0058] Step 5: Slide on the protective film 200 corresponding to the installation groove 111 to attach the protective film 200 to the screen of the electronic device 2000;

[0059] Step 6: Remove the installation frame 100 from the electronic device 2000;

[0060] Step 7: Remove the scraper card 400 from the mounting frame 100;

[0061] Step 8: Use a scraper card 400 to remove air bubbles or air edges between the protective film 200 and the electronic device 2000.

[0062] It is understandable that the order of the above steps can be adjusted appropriately according to the needs of the actual product. For example, step 6 can be interchanged with step 7 or performed simultaneously. In addition, the above steps can also be adjusted appropriately according to the specific structure of the film sticking device 1000. For another example, when the film sticking structure does not have a positioning structure 300, step 4 can be to press the protective film 200 through the mounting groove 111 so that the protective film 200 is attached to the screen of the electronic device 2000, or directly skip step 4 (that is, step 4 is not performed).

[0063] Reference Figure 1 and Figure 2 As shown, it can be understood that the positioning structure 300 is a positioning bar 310, and the positioning bar 310 includes a connecting portion 311 and a supporting portion 312. The connecting portion 311 is accommodated in the mounting groove 111, and the connecting portion 311 is bonded and fixed to the protective film 200, or other detachable connection methods are adopted, which are not specifically limited here. The supporting portion 312 is located at both ends of the connecting portion 311, and the supporting portion 312 abuts against the panel 110, so that the positioning bar 310 can be supported on the panel 110. The positioning bar 310 is detachably connected to the panel 110, and only one of the supporting portions 312 needs to be separated from the panel 110, which makes disassembly more convenient. It can be understood that the positioning bar 310 is elastic, which further improves the convenience of disassembly.

[0064] Reference Figure 2 As shown, it can be understood that the mounting groove 111 is extended along the length direction of the panel 110, so that the size of the mounting groove 111 can be effectively increased when the size of the mounting frame 100 is the same. It can be understood that the longer the length of the mounting groove 111, the more stable the connection between the positioning bar 310 and the protective film 200, so that the positioning accuracy of the protective film 200 is higher. Moreover, increasing the size of the mounting groove 111 can increase the stroke of the user pressing the protective film 200 through the mounting groove 111, which is more conducive to attaching the protective film 200 to the screen of the electronic device 2000, and improving the quality and efficiency of the film.

[0065] Reference Figure 3 and Figure 4 As shown, it can be understood that a positioning groove 113 is provided at one end of the panel 110 facing the positioning cavity. The positioning groove 113 can be formed by a partial structure of the panel 110 being recessed inward. The shape and size of the positioning groove 113 match the shape and size of the protective film 200. The protective film 200 is accommodated in the positioning groove 113. The positioning groove 113 has a positioning effect on the protective film 200, thereby improving the positioning accuracy of the protective film 200, thereby improving the effect and accuracy of the film sticking.

[0066] Reference Figure 2 and Figure 3As shown, it can be understood that a third groove 114 is provided at one end of the panel 110 facing the positioning cavity, and the third groove 114 is located at the periphery of a portion of the positioning groove 113, and the third groove 114 is connected to the positioning groove 113. The provision of the third groove 114 reduces the limiting length of the positioning groove 113 on the protective film 200, and facilitates the installation frame 100 to smoothly separate from the protective film 200 during the film application process, thereby avoiding the situation where the protective film 200 is taken out together with the installation frame 100, resulting in the scrapping of the protective film 200. Moreover, the third groove 114 can facilitate the assembly worker to adjust the position of the protective film 200 and the positioning groove 113, and also facilitate the assembly worker to take the protective film 200 out of the positioning groove 113.

[0067] Reference Figure 2 , Figure 3 and Figure 4 As shown, it can be understood that the enclosure 120 is provided with an avoidance groove 121 for avoiding the protruding part of the electronic device 2000, so that the film sticking device 1000 can be suitable for different electronic devices 2000, and the protruding part of the electronic device 2000 will not cause the installation frame 100 and the electronic device 2000 to be misaligned, thereby causing the problem of inaccurate alignment between the protective film 200 and the screen of the electronic device 2000.

[0068] Reference Figure 1 and Figure 2 As shown, it can be understood that the first notch 112 is spaced apart from the mounting groove 111 to ensure the structural strength of the mounting frame 100. The scraper card 400 is located at one end of the mounting frame 100 along the length direction, and the position arrangement of the scraper card 400 is more reasonable. While ensuring the structural strength of the mounting frame 100, it is easier to remove the scraper card 400 from the mounting frame 100.

[0069] Reference Figure 5 and Figure 6As shown, in another embodiment of the film sticking device 1000 of the present invention, the installation frame 100 includes a panel 110 and a surrounding plate 120, and the panel 110 is provided with a mounting groove 111 and a first notch 112. It can be understood that two side walls of the first notch 112 are provided with a first ridge 115, and correspondingly, the side walls of the scraper card 400 that cooperate with the first ridge 115 are both provided with a first groove 410, and the first groove 410 cooperates with the first ridge 115 to guide the scraper card 400 to be installed in the first notch 112, and to guide the scraper card 400 to be removed from the first notch 112 outward, so that the connection between the scraper card 400 and the installation frame 100 is more stable; and the stability and smoothness of the installation and removal of the scraper card 400 and the installation frame 100 are improved, thereby improving the user experience. It is further explained that the side wall of the first notch 112 away from the opening is provided with a first ridge 115, and correspondingly, one end of the scraper card 400 along the direction of introduction into the first notch 112 is provided with a first groove 410 that cooperates with the first ridge 115, which can further improve the connection stability between the scraper card 400 and the mounting frame 100. It is understandable that the above effect can be achieved by providing at least one side wall of the first notch 112 with a first ridge 115 and the corresponding side wall of the scraper card 400 with a first groove 410 that connects and cooperates with the first ridge 115.

[0070] It should be noted that, as another embodiment, at least one side wall of the first notch 112 may be provided with a first groove 410 , and correspondingly, the side wall of the scraper card 400 is provided with a first ridge 115 that cooperates with the first groove 410 .

[0071] Reference Figure 6 , Figure 7 and Figure 8 As shown, it can be understood that the enclosure 120 is provided with a second notch 122 connected to the first notch 112. The scraper card 400 includes a first plate 420 and a second plate 430 connected to each other, and there is an angle between the first plate 420 and the second plate 430. After the scraper card 400 is installed on the installation frame 100, the first plate 420 covers the first notch 112, and the second plate 430 covers the second notch 122. The scraper card 400 and the installation frame 100 are enclosed to form a positioning cavity, so that the electronic device 2000 can be better positioned in the positioning cavity. Specifically, the first plate 420 is provided with a first groove 410, and the side wall of the first notch 112 is provided with a first convex strip 115, so as to achieve a stable connection between the scraper card 400 and the installation frame 100.

[0072] It is understood that the scratch card 400 includes a first plate 420 and a second plate 430 connected to each other, and there is an angle between the first plate 420 and the second plate 430. A connecting surface 440 is provided on the outer side of the connection between the first plate 420 and the second plate 430. The connecting surface 440 is used to contact the surface of the protective film 200, so as to facilitate manual gripping of the first plate 420 or the second plate 430 and push the operation, so that the protective film 200 is attached to the screen of the electronic device 2000, and at the same time, the bubbles or air edges between the protective film 200 and the screen of the electronic device 2000 are scraped away. It is understood that the connecting surface 440 is provided with a fiber cloth layer (not shown in the figure), and the fiber cloth layer can be bonded to the connecting surface 440, and the fiber cloth layer is in contact with the surface of the protective film 200, which can reduce the wear on the surface of the protective film 200 and improve the film sticking effect. The size of the first plate 420 is longer than that of the second plate 430, which improves the feel of manual grip.

[0073] It is understandable that the first plate 420 is provided with a first limiting structure 421, and the first limiting structure 421 can be an inwardly recessed structure, so as to facilitate manual pushing of the first limiting structure 421 to drive the first plate 420 to move out of the first notch 112, thereby allowing the scraper card 400 to be easily detached from the mounting frame 100.
