[0043] Embodiment one

[0044] As shown in Figure 1 , Figure 4 , the embodiment provides a dustproof cover film-pulling type film applicator for applying a film to a screen of a mobile terminal. The mobile terminal in the embodiment can be a mobile phone 10, and can also be an electronic device such as a tablet computer, an electronic book, a smart watch, etc. For the convenience of structural description of the embodiment, the length direction of the mobile phone 10 is taken as the length direction, the short side direction is taken as the width direction, and the thickness direction is taken as the up-down direction. The parts of the film applicator in the embodiment are described in the above direction. As shown in Figure 3 , Figure 4 , the dustproof cover film-pulling type film applicator adheres a protective film 20 to the screen of the mobile phone 10. The protective film 20 mainly includes a film layer 24, a positioning release layer 21, and a tearing release layer 25. The film layer 24 is used to be attached to the surface of the mobile phone 10, thereby protecting the screen of the mobile phone 10. The positioning release layer 21 is detachably arranged on one side of the film layer 24, and is used to be connected to the film shell. The tearing release layer 25 is arranged on the side of the film layer 24 away from the positioning release layer 21, and faces the mobile phone 10. In use, the positioning release layer 21 and the tearing release layer 25 are pulled away from the film layer 24, and only the film layer 24 is adhered to the surface of the screen of the mobile phone 10.

[0045] As shown in Figure 1 , Figure 2 , the embodiment provides a dustproof cover film-pulling type film applicator, which mainly includes a film shell 100 and a dustproof cover 200. As shown in Figure 2 , Figure 4As shown, the film pasting shell 100 adopts a rectangular structure matched with the mobile phone 10 to be pasted with film, and thus has a length direction, with one end being a front end and the other end being a rear end. The film pasting shell 100 is used to limit the mobile phone 10 to be pasted with film and connect and limit the protective film 20. The dust cover 200 has a length direction, and the two ends of the length direction are respectively provided with a film pressing part 210 and a connecting part 230. The film pressing part 210 can be located at the front end of the dust cover 200, and the connecting part 230 can be located at the rear end of the dust cover 200. The film pressing part 210 is movably arranged on the film pasting shell 100, and the connecting part 230 is used to connect the tear-off release layer 25 of the protective film 20. As shown in Figure 3 、 Figure 5 、 Figure 6 As shown, the tear-off release layer 25 is dragged to separate from the protective film 20 by moving the dust cover 200 in the first direction, and the protective film 20 is pressed onto the mobile phone 10 by driving the film pressing part 210 to move in the first direction. Since the film pressing part 210 drags the protective film 20 downward in the direction from front to rear, when the dust cover 200 is capped on the film pasting shell 100, the film pressing part 210 is located outside the front end of the tear-off release layer 25 of the protective film 20. Thus, when the dust cover 200 is pulled, the tear-off release layer 25 is first torn from the protective film 20 to expose the lower surface (adhesion surface) of the film pasting layer 24 of the protective film 20, and then the film pressing part 210 is pressed onto the film pasting layer 24 of the protective film 20 in the process of continuous movement.

[0046] As shown in Figure 2 、 Figure 3 、 Figure 5 As shown, the dust cover film pasting type film pasting device of the embodiment is used to limit the mobile phone 10 to be pasted with film and the protective film 20 by installing them in the film pasting shell 100, so that the protective film 20 is located above the mobile phone 10. The dust cover 200 is capped, the connecting part 230 at the rear end of the dust cover 200 is used to connect the tear-off release layer 25 of the protective film 20, and the film pressing part 210 at the front end of the dust cover 200 is pressed on the protective film 20. Then the dust cover 200 is pulled in the length direction from front to rear, so that the dust cover 200 drives the connecting part 230 and the film pressing part 210 to move synchronously from front to rear. The connecting part 230 drags the tear-off release layer 25 to separate from the protective film 20, so that the adhesion surface of the protective film 20 is exposed and faces the mobile phone 10. At the same time, the film pressing part 210 is driven to move in the first direction to press the exposed adhesion surface of the protective film 20 onto the mobile phone 10. When the dust cover 200 is pulled to the rear end of the film pasting shell 100, not only the process of tearing the tear-off release layer 25 is completed, but also the process of pressing the protective film 20 to be adhered to the mobile phone 10 is completed synchronously. Moreover, the dust cover 200 opens the film pasting shell 100 to complete the uncapping process. Thus, the film pasting operation is simplified, and the user can use it more conveniently.

[0047] As shown in Figure 3 、 Figure 4 、 Figure 5 ,Figure 6 As shown, further, the connecting portion 230 of the embodiment specifically comprises a hook 231 extending perpendicularly to the inner surface of the dust cover 200 by a predetermined length. In the specific structure, when the dust cover 200 is capped on the film pasting shell 100, the inner surface of the downward surface of the dust cover 200, the hook 231 extends downward by a predetermined length, and the hook of the hook 231 faces away from the film pressing portion 210 (towards the back side). Accordingly, the tear-away release layer 25 is provided with a hanging hole 26 for being sleeved on the hook 231, so as to connect the tear-away release layer 25 to the dust cover 200. The hook 231 facing the back side is more easily hooked into the hanging hole 26, thereby connecting the tear-away release layer 25 to the dust cover 200.

[0048] In another structure (not shown in the figure), the connecting portion can also be a winding rod, and a film passing gap is provided between the winding rod and the dust cover, and the tear-away release layer is wound on the winding rod through the film passing gap, so as to achieve the fixing.

[0049] As shown in Figure 1 , Figure 2 Further, the film pressing portion 210 of the embodiment specifically comprises a support frame 211 and a film pressing piece 220. The support frame 211 is fixedly arranged on the dust cover 200, and the film pressing piece 220 is arranged on the support frame 211 to press the protective film 20 through the movement of the dust cover 200. In the specific structure, the support frame 211 can be integrally formed with the dust cover 200, or can be a separate structure and detachably assembled with the dust cover 200. The support frame 211 mainly provides a mounting position for the film pressing piece 220, so that the film pressing piece 220 can be stably connected to the front end of the dust cover 200.

[0050] Further, the film pressing piece 220 of the embodiment can include various forms, of which the first form can be a roller 221 rotatably arranged on the support frame 211. When the film pressing portion 210 moves along the length direction to press the film, the roller 221 rotates and presses the protective film 20 downward, so as to bond the film pasting layer 24 of the protective film 20 to the screen of the mobile phone 10. The second form of the film pressing piece 220 can be a pressing block fixedly arranged on the support frame 211. When the film pressing portion 210 moves along the length direction to press the film, the pressing block slides and presses the protective film 20 downward, so as to bond the film pasting layer 24 of the protective film 20 to the screen of the mobile phone 10. It should be noted that the support frame 211 can be provided with a plurality of different mounting positions, and different film pressing pieces 220 can be selected according to the type of film pasting or the thickness of the mobile phone 10, so as to have strong universality and save production cost.

[0051] As shown in Figure 1 , Figure 2 , Figure 4As shown, further, the protective film shell 100 of the present embodiment specifically comprises: a shell 110, an elastic member 130, a first limiting portion 140, and a second limiting portion 150. The shell 110 is provided with a receiving cavity 120 for receiving and limiting a mobile terminal to be pasted with a protective film. The film pressing portion 210 is movably connected to the shell 110 along a first direction. The elastic member 130 is located at one end of the length direction of the receiving cavity 120. One end of the elastic member 130 is connected to the shell 110, and the other end is movably arranged. The elastic member 130 is provided with the first limiting portion 140. The second limiting portion 150 is arranged at the other end of the length direction of the shell 110. The first limiting portion 140 and the second limiting portion 150 are respectively connected to the positioning release layer 21 of the protective film 20. The elastic member 130 supports the protective film 20 to be connected and limited on the shell 110 and spaced apart from the mobile phone 10 by a predetermined distance in the up-down direction. In the specific structure, the opening of the receiving cavity 120 faces upward. The elastic member 130 is located at one side of the length direction of the receiving cavity 120. One end of the elastic member 130 movably suspends towards the center of the receiving cavity 120, so that the elastic member 130 has a certain resilience after being extruded by the film pressing portion 210. The movable end of the elastic member 130 extends towards the center of the receiving cavity 120 and can move downward under extrusion and rebound upward after being released. The first limiting portion 140 on the elastic member 130 is arranged outside the length direction of the mobile phone 10. The first limiting portion 140 and the elastic member 130 can be integrally formed by injection molding. The elastic member 130 and the shell 110 can be integrally formed by injection molding. The second limiting portion 150 is integrally formed at the other end of the length direction of the shell 110. The two ends of the positioning release layer 21 of the protective film 20 are connected by the first limiting portion 140 and the second limiting portion 150, so that the protective film 20 is positioned above the supporting limiting portion and spaced apart from the mobile phone 10 by a predetermined distance. After the positioning release layer 21 of the protective film 20 is connected to the first limiting portion 140 and the second limiting portion 150, the entire protective film 20 is located above the screen of the mobile phone 10. Then, the tear release layer 25 of the protective film 20 is torn away from the pasting layer 24. The tear release layer 25 contacts the screen of the mobile phone 10 during the tearing process, thereby dusting the screen of the mobile phone 10. After the tear release layer 25 is torn away, the pasting layer 24 and the positioning release layer 21 are still located above the screen under the support of the movable end of the elastic member 130, thereby avoiding the pasting layer 24 from prematurely contacting the screen. The elastic member 130 is also pressed downward by the film pressing portion 210 during movement, thereby enabling the pasting layer 24 of the protective film 20 to be bonded to the screen of the mobile phone 10 below. During the rebounding process of the elastic member 130, the positioning release layer 21 is torn away from the pasting layer 24, thereby facilitating the user to finally remove the positioning release layer 21 from the pasting layer 24.

[0052] AsFigure 2 、 Figure 4 Further, as shown in FIG. 1, the support limiting part is integrally formed with the shell 110, and is distributed around the accommodating inner cavity 120 and forms a limiting area. A limiting step is formed on the side of the support limiting part facing the limiting area, and abuts against the back and the length-width direction side of the mobile phone 10, thereby limiting the mobile phone 10 to be pasted with the protective film.

[0053] As shown in FIG. 1, the dust cover 200 is arranged on the length direction side of the shell 110, and is connected with the shell 110 in a detachable manner. Figure 2 、 Figure 4 Further, as shown in FIG. 1, the two length direction side inner walls of the shell 110 are provided with a guide groove 160, and the dust cover 200 is matched with the guide groove 160 to move along the length direction. In one mode (not shown in the drawing), the dust cover 200 can be connected to the pasting film shell 100 in a detachable manner, that is, when the mobile phone 10 and the protective film 20 need to be installed, the dust cover 200 is opened to separate the dust cover 200 from the pasting film shell 100, and after the mobile phone 10 and the protective film 20 are installed in the shell 110, the dust cover 200 is again opened on the pasting film shell 100. Then the dust cover 200 can be embedded in the guide groove 160 through the guide column 213 to slide in the front-back direction.

[0054] As shown in FIG. 1, the dust cover 200 can be in the form of a flip cover, specifically: the dust cover 200 is reversibly arranged at one end of the length direction of the shell 110 through the film pressing part 210, so as to have a side flip state and a film pressing state. In the side flip state, the film pressing part 220 is flipped to the outside of the length direction of the elastic part 130 to avoid the first limiting part 140; in the film pressing state, the film pressing part 220 is flipped above the elastic part 130 and can move along the length direction to press the protective film 20. In the use process, only flipping is needed to convert the side flip state and the film pressing state, and the operation is more simple and the use is more convenient. Figure 2 、 Figure 3 As shown in FIG. 1, the dust cover 200 can be in the form of a flip cover, specifically: the dust cover 200 is reversibly arranged at one end of the length direction of the shell 110 through the film pressing part 210, so as to have a side flip state and a film pressing state.
