Description

Technical Field

[0001] The present application relates to the field of film sticking tools, and in particular to a film sticking device and a film sticking kit for electronic display screens. Background Art

[0002] In order to protect the screens of terminal devices such as mobile phones and tablets, users usually stick a layer of film on the flat surface of the terminal device (device to be filmed) to prevent the touch screen from being scratched. During the filming process, in order to pursue the flatness of the lines and not to generate bubbles, so that the appearance of the terminal device remains beautiful, a film applicator is usually used to assist the user in accurate positioning and filming, so that the filming effect can be improved. The existing film applicator usually sets a limiting part at one end of the shell, and connects and limits the positioning release layer of the protective film through the limiting part, so that the protective film is fixed above the electronic display screen of the device to be filmed, and then the tearing release layer of the protective film is pulled open to expose the film layer (the film to be actually attached to the screen surface), and then the protective film can be pressed to attach the film layer to the screen surface. However, the current limiting part directly adopts the form of a boss, and the holes on the positioning release layer are directly sleeved on the boss. In the process of pulling the tearing release layer, the protective film is easily deformed by the external force, which easily causes the holes in the positioning release layer to slide off the limiting part, causing the filming process to fail.

[0003] Therefore, the prior art still needs to be improved and developed. Utility Model Content

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0036] With the increasing attention paid to the environment, more and more products are manufactured using fully degradable materials. Since paper is fully degradable, it is considered possible to directly use a paper film applicator shell. However, in the process of using the pulp pressure process to make the limit part, it is impossible to process a limit part structure similar to an inverted buckle, and only the form of a boss can be used. The resulting hook action of the boss is unstable, and the hooked object is easy to slide off the boss, making it impossible to firmly position some functional parts (such as the positioning release layer of the protective film). In order to prevent the protective film from falling off due to external force when the film applicator pulls out the release layer during the film applicator process, the present application proposes the following embodiments.

[0037] Embodiment 1

[0038] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment proposes a film applicator for an electronic display screen, which is used to apply film to the screen of the device to be filmed. The device to be filmed in this embodiment can be various mobile terminals, such as mobile phones 10, tablet computers, e-books, smart watches and other electronic devices. To facilitate the structural description of this embodiment, the mobile phone 10 is used as an example for explanation. The long side direction of the mobile phone 10 is the length direction, the short side direction is the width direction, and the thickness direction is the up-down direction. Figure 2 , Figure 3 , Figure 5 As shown, the film applicator for electronic display screen is used to adhere the protective film 400 to the screen of the mobile phone 10. The protective film 400 mainly includes: a film layer 410, a positioning release layer 420 and a tearing release layer 430. The film layer 410 (the film to be actually attached to the screen surface) is used to be attached to the surface of the mobile phone 10, so as to protect the screen of the mobile phone 10; the positioning release layer 420 can be detachably arranged on one side of the film layer 410, and the positioning release layer 420 is used to be connected to the film applicator for electronic display screen. The tearing release layer 430 is arranged on the side of the film layer 410 away from the positioning release layer 420 and facing the mobile phone 10. When in use, the positioning release layer 420 and the tearing release layer 430 are both pulled away from the film layer 410, and only the film layer 410 is adhered to the screen surface of the mobile phone 10.

[0039] like Figure 1 , Figure 2 , Figure 3As shown, the film applicator for electronic display screens of this embodiment mainly includes: a housing 100, a first limiting portion 200 and a sleeve pressing member 300. A receiving chamber 110 is provided in the housing 100 and is used to accommodate and limit the position of the mobile phone 10 to be filmed. For the convenience of structural description, the housing 100 adopts a rectangular structure matching the outline of the mobile phone 10 in the horizontal direction, and the two ends of the housing 100 in the length direction are respectively opposite front and rear ends. The middle of the housing 100 is concave downward to form the receiving chamber 110, and the receiving chamber 110 is open upward to form a film-applying opening. The receiving chamber 110 is also set to a rectangular shape, which is easy to place the mobile phone 10 to be filmed. In order to facilitate the limiting of the mobile phone 10, corresponding limiting strips are protruded on the inner walls around the receiving chamber 110, and the surface of the limiting strips is abutted against the side of the mobile phone 10, so that the mobile phone 10 is stably fixed in the receiving chamber 110. The first limiting portion 200 is located at one end of the shell 100 in the length direction, and is used to connect and limit the protective film 400 so that the protective film 400 is located above the electronic display screen of the device to be film-applied. In the specific structure, the first limiting portion 200 is set at the middle position of the front end of the shell 100 and protrudes from the upper surface of the shell 100. When applying the film, it is necessary to tear off the tear-off layer 430 first, and the tear-off layer 430 is slowly torn from the front to the back direction. Therefore, the first limiting portion 200 is located on the shell 100. One end of the tear-off layer 430 is first separated. The sleeve pressing piece 300 can be detachably arranged on the first limiting portion 200, and is used to prevent the protective film 400 from falling off from the upper end of the first limiting portion 200. The sleeve pressing piece 300 can adopt a variety of structures, and can be connected to the shell 100 or set separately. When in use, it is directly connected to the first limiting portion 200 and covers or sleeves on the upper end of the first limiting portion 200, so that the protective film 400 is located below the sleeve pressing piece 300, and the sleeve pressing piece 300 will not be dragged by the protective film 400 and easily separated from the first limiting portion 200.

[0040] The film applicator for the electronic display screen of this embodiment places the mobile phone 10 to be film-applied in the accommodating cavity 110 so that the mobile phone 10 does not move at the predetermined position of the housing 100, connects the positioning release layer 420 of the protective film 400 to the first limiting portion 200 at the front end, and limits the protective film 400 through the first limiting portion 200 so that the protective film 400 is located above the screen of the mobile phone 10. In this way, both the mobile phone 10 and the protective film 400 are limited, so that the protective film 400 is aligned with the screen of the mobile phone 10, and then the film is applied, which ensures the accuracy of the film application process. When applying the film, the sleeve pressing piece 300 is first separated from the first limiting portion 200 to expose the first limiting portion 200, so that the protective film 400 can be smoothly covered on the first limiting portion 200, so that the protective film 400 can be limited and limited with the electronic display screen. Then the sleeve pressing member 300 is installed on the upper end of the first limiting portion 200, so as to seal the upper end of the first limiting portion 200. In the process of tearing off the release layer, the protective film 400 will not be separated from the upper end of the first limiting portion 200, thereby improving the success rate of film application. In particular, the problem that the first limiting portion 200 can only be processed into a boss during the processing of paper materials, which causes the protective film 400 to easily slide off the boss, can be effectively solved.

[0041] like Figure 2 , Figure 3 , Figure 4 As shown in the specific structure, the sleeve pressing member 300 in this embodiment includes a pressing plate 310, and a docking groove 320 is formed on the surface of the pressing plate 310. The docking groove 320 is used to be sleeved on the first limiting part 200, so that the protective film 400 sleeved on the first limiting part 200 is located below the pressing plate 310. In the specific structure, the pressing plate 310 adopts a waist-shaped plate or a square block, and the length and width of the plate are both larger than the length and width of the first limiting part 200. Therefore, after being connected to the first limiting part 200, it can protrude from the side of the first limiting part 200 to block the protective film 400 sleeved on the first limiting part 200. The inner wall of the concave docking groove 320 abuts against the outer wall of the first limiting part 200, and the docking groove 320 is tightly fitted in the process of sleeved on the first limiting part 200, so that the pressing plate 310 is not easy to fall off from the first limiting part 200 through the docking groove 320.

[0042] like Figure 2 , Figure 3 , Figure 4As shown, the depth of the docking groove 320 in this embodiment is slightly smaller than the height of the first limiting portion 200, so that after the docking groove 320 is completely sleeved on the first limiting portion 200, the pressing plate 310 can be smoothly pressed on the protective film 400, so that in the process of pulling and tearing the release layer 430, the front end of the protective film 400 is pressed by the pressing plate 310 in the up and down directions, thereby fixing the protective film 400, effectively preventing the protective film 400 from falling off due to force when the release film is pulled out during the film pasting process.

[0043] It is easy to imagine that the docking groove 320 can be replaced by an opening, but the docking groove 320 has a large contact area with the first limiting portion 200, and a large connection force is generated by squeezing, so it will not be pushed open by the protective film 400. The opening is not as stable as the docking groove 320.

[0044] like Figure 1 , Figure 3 , Figure 4 As shown, further, the sleeve pressing piece 300 of this embodiment is connected to the housing 100, so that the user can directly apply the film when the film applicator is in use, which is convenient for the film application process. If the sleeve pressing piece 300 is set separately, firstly, the sleeve pressing piece 300 needs to be found everywhere, and secondly, the sleeve pressing piece 300 is easy to be ignored and the use of the sleeve pressing piece 300 is not understood. Therefore, the structure in which the sleeve pressing piece 300 is connected to the housing 100 makes the film application process more convenient.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown in the specific structure, one end of the sleeve pressing member 300 is connected to a folding member 330, and the other end of the folding member 330 is connected to the housing 100. The sleeve pressing member 300 is sleeved on or detached from the first limiting portion 200 by bending the folding member 330. The folding member 330 is connected to the front end outer wall of the housing 100, so that after the sleeve pressing member 300 is detached from the first limiting portion 200, the sleeve pressing member 300 is kept away from the vicinity of the first limiting portion 200, and will not affect the sleeve of the positioning release layer 420 of the protective film 400 on the first limiting portion 200.

[0046] like Figure 2 , Figure 3 , Figure 4As shown, further, the folding member 330 in this embodiment includes a flip plate 331, and a folding line 332 is provided at the connection between the flip plate 331 and the sleeve pressing member 300 and the connection with the shell 100, and the folding line 332 is extended along the width direction. The folding line 332 is conducive to the bending and deformation of the flip plate 331, thereby avoiding the flip plate 331 from breaking. There are various structural forms of the folding line 332, such as directly using a material reduction groove to make the material at the connection thinner, which is conducive to deformation. In another structure, the folding line 332 is formed by a plurality of strip seams arranged at intervals at the connection. In this way, while ensuring the connection stability of the flip plate 331, flexible bending is achieved, so that the flip plate 331 is not easy to break at the connection.

[0047] like Figure 1 , Figure 2 , Figure 3 As shown, further, the first limiting portion 200 in this embodiment includes a first waist-shaped boss 210, and the first waist-shaped boss 210 extends a predetermined length in the width direction. The first waist-shaped boss 210 corresponds to the front end pull hole 421 of the positioning release layer 420 connected to the protective film 400, and the shape of the pull hole 421 matches the outer contour of the first waist-shaped boss 210. When the positioning release layer 420 is connected to the first waist-shaped boss 210, the position of the protective film 400 in the front and rear directions of the housing 100 is roughly fixed, and the position in the left and right directions is limited, so that the approximate positioning can be achieved.

[0048] like Figure 2 , Figure 3 , Figure 4 As shown, further, a first pad 211 is provided on the upper surface of the shell 100 in this embodiment, and a first waist-shaped boss 210 is protrudingly arranged on the upper surface of the first pad 211; the first pad 211 is used to lift the protective film 400 so as to form a tearing gap between the protective film 400 and the electronic display screen. The upper surface of the first pad 211 is used to limit the front end of the protective film 400 in the upper and lower directions of the shell 100, so that a tearing gap 150 can be formed below the protective film 400, and the tearing gap 150 provides space for the tear-off layer 430 to fall off, so that the front end of the tear-off layer 430 is first separated from the film layer 410 and then bent toward the electronic display screen, and the bent tear-off layer 430 is slowly pulled out toward the rear, and during the pulling process, the bent tear-off layer 430 contacts the electronic display screen below and can take away dust.

[0049] like Figure 1 , Figure 2 , Figure 3As shown, further, a second limiting portion 220 is provided at one end of the housing 100 opposite to the first limiting portion 200 in the length direction; the second limiting portion 220 and the first limiting portion 200 are respectively used to connect the two ends of the protective film 400 in the length direction to limit the protective film 400. The second limiting portion 220 includes: at least two second waist-shaped bosses 221, at least two second waist-shaped bosses 221 are arranged at intervals along the width direction, and the second waist-shaped bosses 221 are extended along the length direction. In the specific structure, a pull hole 421 is provided on one end of the positioning release layer 420 of the protective film 400, through which the first waist-shaped boss 210 can be hung. The waist-shaped structure of the first waist-shaped boss 210 can limit the front end of the protective film 400 in the width direction, so that the protective film 400 can be aligned with the mobile phone 10 below in the width direction, and the pull hole 421 and the first waist-shaped boss 210 are matched and set. When the two are connected in place, they can be aligned with the mobile phone 10 after pressing in the length direction, so that the film can be attached. The function of the second waist-shaped boss 221 can be similar to that of the first waist-shaped boss 210. The rear end of the positioning release layer 420 of the protective film 400 is sleeved and limited, and the limiting hole 422 at the other end of the protective film 400 is inserted into the second waist-shaped boss 221, so that the first waist-shaped boss 210 and the second waist-shaped boss 221 prevent the protective film 400 from moving in the width direction, so as to achieve more stable limiting.

[0050] like Figure 1 , Figure 2 , Figure 3 As shown, further, the two ends of the shell 100 in the length direction respectively form a concave first end groove surface 120 and a concave second end groove surface 130. The first pad 211 is located on the first end groove surface 120, and at least two second waist-shaped bosses 221 are both located on the second end groove surface 130, and are respectively located on both sides of the terminal accommodating cavity 110. In this way, the concave first end groove surface 120 and the concave second end groove surface 130 form a side baffle structure on the left and right sides of the shell 100. During the film application process, the protective film 400 is located on the inner side of the side baffle structure on both sides, which plays a certain alignment role.

[0051] like Figure 1 As shown, a push-out hole 140 penetrating the housing 100 is provided at the bottom of the terminal housing cavity 110, and the push-out hole 140 is waist-shaped. When the film is applied and the mobile phone 10 needs to be taken out of the housing 100, the mobile phone 10 can be pushed directly from the push-out hole 140, so that the mobile phone 10 can be pushed out of the housing 100, making it easier to take out the mobile phone 10.

[0052] The shell 100 of the film applicator of this embodiment can be made of paper materials, such as a pulp molded shell, or other plastic materials, such as a blister shell.

[0053] Embodiment 2

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, this embodiment also proposes a film sticking kit, which includes a film sticking device for an electronic display screen and a protective film 400 as described above. The protective film 400 in this embodiment specifically includes: a film sticking layer 410, a positioning release layer 420, and a tear-off release layer 430. The film sticking layer 410 is used to be attached to the surface of the mobile phone 10, so as to protect the screen of the mobile phone 10; the positioning release layer 420 can be detachably arranged on one side of the film sticking layer 410, and the positioning release layer 420 is used to be connected to the film sticking device. A pull hole 421 is arranged on one end of the length direction of the positioning release layer 420, and a limiting hole 422 is arranged on the other end; the pull hole 421 can be sleeved on the first waist-shaped boss 210; the limiting hole 422 is used to be sleeved on the second waist-shaped boss 221 for limiting. The tear-off release layer 430 is arranged on the side of the film sticking layer 410 away from the positioning release layer 420, and faces the mobile phone 10.

[0055] like Figure 2 , Figure 3 , Figure 5 As shown, when in use, the mobile phone 10 is first placed in the accommodating cavity 110 for limiting, the pulling hole 421 of the positioning release layer 420 is sleeved on the first waist-shaped boss 210, and the limiting hole 422 of the positioning release layer 420 is sleeved on the second waist-shaped boss 221, so that the protective film 400 is limited on the housing 100. Then the sleeve pressing piece 300 is installed on the first waist-shaped boss 210, and the positioning release layer 420 of the protective film 400 can be pressed by the pressing plate 310, so that in the process of pulling and tearing the release layer 430, the front end of the positioning release layer 420 is pressed by the pressing plate 310 in the up and down direction. After the tear-off layer 430 is pulled out, the film layer 410 is exposed, and the protective film 400 is pressed from above the positioning release layer 420 so that the film layer 410 is adhered to the screen of the mobile phone 10. Then the sleeve pressing piece 300 is removed, and the positioning release layer 420 is torn off to complete the film application.

[0056] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
