[0040] Embodiment 1:

[0041] like Figure 1 and Figure 2 As shown, a mobile terminal film-sticking device provided in an embodiment of the present application is now described. The mobile terminal film-sticking device is used to stick the protective film 4 on the screen of the mobile terminal 6. The protective film 4 includes a protective adhesive film (not shown in the figure) and a release film (not shown in the figure) stacked. The protective adhesive film and the release film are the same size. The release film can be torn off so that the protective adhesive film can be adhered to the screen to protect the screen. In this embodiment, the protective film 4 can be a soft film, a tempered film or a 3D film. When the protective film 4 is a soft film, the protective film 4 is automatically cut according to the model of the mobile terminal 6 by a film cutting machine, so that the protective adhesive film and the release film are both one piece, which solves the problem of thin lines in the prior art due to two release films on the protective adhesive film.

[0042] Specifically, the mobile terminal film pasting device includes a base 1, a positioning adhesive sheet 3, a rolling member ( Figure 1-3The base 1 is provided with a placement groove 111 for positioning the mobile terminal 6, and the positioning adhesive sheet 3 is used to adhere the release film to the screen of the mobile terminal 6 so that the protective adhesive film is aligned with the screen. The first rotating film assembly 2 is used to separate the protective film 4 and the positioning adhesive sheet 3 aligned with the screen from the screen and adhere them to the first rotating film assembly 2. After the release film is torn off, the first rotating film assembly 2 is closed, and the protective adhesive film is aligned with the screen again. Under the action of the rolling member rolling the first rotating film assembly 2, the protective adhesive film is aligned and attached to the screen.

[0043] In this embodiment, the positioning adhesive sheet 3 is a double-sided adhesive sheet, which is mainly used to align the protective film 4 with the screen, so that the protective film 4 and the screen are still in an aligned state after the protective film 4 is transferred to the first rotating film assembly 2, ensuring the accuracy of the film; the roller is used to apply a uniform roller pressure to the protective film 4 to ensure that no bubbles appear during the process of the protective film 4 being attached to the screen. The positioning adhesive sheet 3 is a transparent sheet structure.

[0044] A mobile terminal film pasting device provided in an embodiment of the present application realizes the positioning of a protective film 4 and a screen through a first rotating film assembly 2 and a positioning adhesive sheet 3. Compared with the prior art, there is no need to adjust while pasting the film, and it has the advantages of simple operation, precise positioning, high film pasting efficiency and good film pasting effect.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, a sticky silicone pad 112 is provided at the bottom of the placement groove 111, and the silicone pad 112 is used to stick the mobile terminal 6, and has a positioning effect on the mobile terminal 6 to prevent the mobile terminal 6 from shifting during the film application process. At this time, the mobile terminal 6 can be placed at any position in the placement groove 111 at will.

[0046] Specifically, in this embodiment, the size of the placement slot 111 is larger than the size of the mobile terminal 6, so that the mobile terminal film-applying device of the present application can apply films to mobile terminals 6 of different models, thereby improving practicality and market competitiveness, and the mobile terminal 6 can be placed in contact with the adjacent two side walls of the placement slot 111. In other embodiments, the size of the placement slot 111 matches the size of the mobile terminal 6.

[0047] like Figure 1 and Figure 3As shown, in this embodiment, the first rotating film assembly 2 includes a first clamping member 22 rotatably disposed on one end of the base 1, and a first positioning film tearing sheet 21 clamped at one end by the first clamping member 22. A first positioning column 113 is provided at one end of the base 1 away from the first clamping member 22, and a first positioning hole 212 sleeved with the first positioning column 113 is provided at one end of the first positioning film tearing sheet 21 away from the first clamping member 22. Specifically, the first clamping member 22 includes a rotating sheet 221 rotatably disposed on the base 1 and a clamping sheet 222 detachably connected to the rotating sheet 221, and one end of the first positioning film tearing sheet 21 is clamped by the rotating sheet 221 and the clamping sheet 222. The rotating piece 221 and the clamping piece 222 are detachably connected, so that the first positioning tearing film piece 21 can be replaced. The first positioning tearing film piece 21 is provided with a first adhesive area 211, and the first adhesive area 211 is used to adhere to the non-adhesive surface of the protective adhesive film. When the first adhesive area 211 on the first positioning tearing film piece 21 is not sticky enough, the first positioning tearing film piece 21 can be replaced. The first positioning tearing film piece 21 is a transparent sheet structure.

[0048] Specifically, Figure 2 and Figure 3 As shown, the rotating piece 221 is provided with a stud 2211 with a threaded hole, the clamping piece 222 is provided with a first through hole 2221 sleeved with the stud 2211, the first positioning tearing film piece 21 is provided with a second through hole 213 sleeved with the stud 2211, and the stud 2211 is screwed with a screw to press the clamping piece 222. The rotating piece 221 and the clamping piece 222 are detachably connected by screws, which has the advantage of convenient disassembly and assembly. The second through hole 213 is sleeved on the stud 2211 to prevent the first positioning tearing film piece 21 from being separated from the first clamping piece 22.

[0049] In this embodiment, two installation columns 114 with installation holes are arranged at intervals on the base 1, and a hollow column 2212 with a through hole is provided on the rotating piece 221. An elastic connecting rod is passed through the hollow column 2212, and both ends of the elastic connecting rod are respectively inserted into the installation holes of the two installation columns 114, thereby realizing the rotation setting of the rotating piece 221.

[0050] like Figure 2 As shown, in this embodiment, the first adhesive area 211 on the first positioning tear film sheet 21 is arranged on the side facing the base 1, and the first adhesive area 211 is used to adhere to the non-adhesive surface of the protective adhesive film, and the adhesive surface of the protective adhesive film is used to stick the film to the screen, and the viscosity of the first adhesive area 211 is less than that of the protective adhesive film. In this way, when the protective adhesive film is adhered to the screen, the protective adhesive film will not be separated from the screen when the first positioning tear film sheet 21 is separated from the protective adhesive film, thereby ensuring the film sticking effect.

[0051] like Figure 2As shown, in this embodiment, the size of the positioning adhesive sheet 3 is smaller than the size of the protective film 4, and the viscosity of the positioning adhesive sheet 3 is smaller than the viscosity of the first positioning tear film sheet 21 and smaller than the viscosity of the isolation film and the protective adhesive film, so that the first positioning tear film sheet 21 can smoothly take the positioning adhesive sheet 3 away from the screen to achieve the positioning transfer of the protective film 4. The area of ​​the first adhesive area 211 is larger than the area of ​​the protective film 4 and smaller than the area of ​​the first positioning tear film sheet 21.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, the function of the first positioning column 113 and the first positioning hole 212 is to ensure that the protective film 44 on the first positioning tear film sheet 21 is aligned with the screen when the first positioning tear film sheet 21 is closed. In this embodiment, the first positioning tear film sheet 21 is a PET film with a thickness of 0.5-2mm. When the first positioning tear film sheet 21 is closed, there is a spacing between the first positioning tear film sheet 21 and the screen, and the spacing is 1-3mm. The spacing is used to ensure that the protective adhesive film will not fit with the screen when it is not subjected to the roller pressure of the roller pressing member 7, thereby effectively preventing the generation of bubbles. In this embodiment, the placement groove 111 is a rectangular groove, and the first positioning columns 113 are provided at both ends of the placement groove 111 in the length direction. Correspondingly, the first positioning tear film sheet 21 is provided with one-to-one corresponding first positioning holes 212.

[0053] like Figure 2 As shown, in this embodiment, the base 1 includes an upper shell 11 and a lower shell 12 which are rotatably connected, a placement groove 111, a first clamping member 22 and a first positioning column 113 are all arranged on the upper shell 11, and a receiving groove is arranged in the lower shell 12 for placing the rolling member.

[0054] Specifically, a plurality of partition plates 121 are provided in the receiving groove to divide the receiving groove into a plurality of partition grooves 122. In addition to being used to place the roller pressing member, each partition groove 122 is also used to place different auxiliary tools, such as a scraper, an adhesive sheet, cleaning cotton and a cleaning cloth. In this embodiment, the roller pressing member includes a T-shaped handle and a roller shaft rotatably arranged on the T-shaped handle, and a rubber sleeve is provided on the surface of the roller shaft.

[0055] Embodiment 2:

[0056] The main differences between this embodiment and the first embodiment are that the second rotating diaphragm assembly 5 and the first rotating diaphragm assembly 2 have different structures, and the structures of the rolling member 7 and the base 1 are different.

[0057] Specifically, Figure 4 , Figure 5 and Figure 7As shown, the second rotating film assembly 5 includes a frame shell 51 that is rotatably disposed on one end of the base 1 and can cover the base 1, a second positioning film tearing sheet 52 that is sleeved on the frame shell 51, and a second clamping member 53 that clamps one end of the second positioning film tearing sheet 52. A plurality of second positioning posts 511 are provided on the side of the frame shell 51 facing the base 1, and a second positioning hole 522 that is sleeved with the second positioning post 511 is provided on the second positioning film tearing sheet 52.

[0058] Specifically, Figure 5 and Figure 6 As shown, the second positioning posts 511 are distributed at both ends of the placement slot 111 in the length direction, and the second positioning tear film sheet 52 is provided with second positioning holes 522 corresponding to the second positioning posts 511. During installation, the second positioning tear film sheet 52 is firstly sleeved on the second positioning posts 511, and then clamped and fixed by the second clamping member 53.

[0059] like Figure 7 As shown, a second adhesive region 521 is provided on the side of the second positioning tear film sheet 52 facing the base 1, the adhesive area of ​​the second adhesive region 521 is larger than the area of ​​the protective film 4, the viscosity of the second adhesive region 521 is smaller than the viscosity of the protective adhesive film and the release film, and the viscosity of the second adhesive region 521 is greater than the viscosity of the positioning adhesive sheet 3. A release film is provided on the second positioning tear film sheet 52 or the second adhesive region 521 for safe storage when the second positioning tear film sheet 52 is not in use.

[0060] like Figure 5 As shown, in this embodiment, when the frame shell 51 and the base 1 are covered, the number of the second positioning posts 511 distributed at both ends of the placement groove 111 in the length direction is inconsistent, and the second positioning holes 522 at both ends of the second positioning tear film sheet 52 correspond to the second positioning posts 511 one by one. The inconsistent number of the second positioning posts 511 at both ends is used to prevent fooling. Specifically, three second positioning posts 511 are provided on one end of the frame shell 51, and two second positioning posts 511 are provided on the other end. Among them, the spacing between two adjacent second positioning posts 511 in the three second positioning posts 511 on the same end is inconsistent, which ensures that the second positioning tear film sheet 52 is uniquely sleeved on the second positioning post 511 through the second positioning hole 522, thereby improving the installation efficiency. The base 1 is provided with a plug-in hole 18 for each second positioning post 511 to be inserted, and the function of the plug-in hole 18 is to prevent the second positioning tear film sheet 52 from being separated from the second positioning post 511.

[0061] like Figure 5As shown, in this embodiment, the adjacent two side walls in the placement groove 111 are positioning walls 13, and a corner of the mobile terminal 6 is placed in the placement groove 111 in contact with the positioning wall 13. At this time, the mobile terminal film pasting device can be used to paste a special protective film, which includes a positioning film, a protective adhesive film and a release film that are sequentially pasted together. The positioning film is provided with a third positioning hole, and the third positioning hole is used to be sleeved with the second positioning column 511, so as to achieve the positioning alignment of the protective adhesive film and the screen. In this embodiment, the placement groove 111 includes a left side wall, a right side wall, an upper side wall and a lower side wall, wherein the lower left wall composed of the left side wall and the lower side wall is the positioning wall 13, and the lower left corner of the mobile terminal 6 is placed in contact with the positioning wall 13 in the placement groove 111 with the screen facing up. In other embodiments, the upper left wall, the upper right wall or the lower right wall of the placement groove 111 is the positioning wall 13.

[0062] like Figure 5 As shown, in this embodiment, a clearance groove 14 is provided on the positioning wall 13. Specifically, a clearance groove 14 is provided on the left side wall of the placement groove 111. The setting of the clearance groove 14 is used to avoid air for some mobile terminals 6 with buttons on the left side, ensuring that the mobile terminal 6 fits tightly with the positioning wall 13, so as to be applicable to more mobile terminals 6. The buttons may be switch buttons and volume buttons.

[0063] In this embodiment, when the frame shell 51 is covered with the base 1, there is a gap between the protective film 4 and the screen of the mobile terminal 6. The setting of this gap is used to prevent the protective adhesive film from being attached to the screen when it is not rolled by the rolling member 7, so as to prevent the generation of bubbles. The gap is 1-3mm. At present, the thickness of the mobile terminal 6 is generally 8-11mm, and the thickness difference is within this gap, so it can be applied to most mobile terminals 6. Of course, for some particularly thick or thin mobile terminals 6, the gap can be adjusted by adding or reducing the silicone pad 112.

[0064] like Figure 5 As shown, in this embodiment, the base 1 is provided with a strip-shaped card slot 15, and a strip-shaped card block 512 that can be inserted into the strip-shaped card slot 15 is provided on one side of the frame shell 51 close to the base 1, and a plurality of positioning slots 16 distributed at intervals are provided on the base 11, and a positioning block 513 that is plugged into the corresponding positioning slots 16 is provided on the frame shell 51. Two strip-shaped card slots 15 are provided in parallel and are located on the left and right sides of the placement slot 111, and four positioning slots 16 are provided. In this embodiment, the strip-shaped card slot 15, the strip-shaped card block 512, the positioning slot 16 and the positioning block 513 are all used to ensure the accuracy of the frame shell 51 and the base 11 covering each other, to prevent position deviation after the frame shell 51 and the base 1 are covered, and to ensure the accuracy of the rolling of the film by the rolling member 7.

[0065] like Figure 5As shown, in this embodiment, the base 1 is provided with a take-out slot 17 which connects the bar-shaped card slot 15 and the placement slot 111. The function of the take-out slot 17 is to facilitate taking out the mobile terminal 6 after the film is applied.

[0066] like Figure 5 As shown, in this embodiment, the base 1 and the frame shell 51 are hinged by two hinges 8, and the hinges 8 are metal hinges 8. The hinges 8 are fixed to the base 1 and the frame shell 51 by screws. The base 1 and the frame shell 51 are both made of plastic parts, which is convenient for reducing weight and mass production.

[0067] Specifically, Figure 5 and Figure 6 As shown, the second clamping member 53 includes a rotating block 531 rotatably arranged on the frame shell 51, a first magnet 532 arranged on the rotating block 531, and a second magnet 533 arranged on the frame shell 51 and attracted to the first magnet 532. The first magnet 532 and the second magnet 533 are attracted to each other and fit together to clamp the second positioning tearing film sheet 52. The rotating block 531 is used to facilitate the separation of the first magnet 532 and the second magnet 533, so that the second positioning tearing film sheet 52 can be detachably installed.

[0068] Specifically, Figure 8 and Fig. 9 As shown, the rolling member 7 is slidably disposed on the frame shell 51, and the rolling member 7 includes two guide rails 71 spaced apart on the frame shell 51, mounting seats 72 slidably disposed on each guide rail 71, rollers 73 rotatably disposed on the mounting seats 72 at both ends, and an operating handle 74 connecting the two mounting seats 72, and the rollers 73 are used to roll the second positioning tearing film sheet 52 so that the protective adhesive film is attached to the screen of the mobile terminal 6. Specifically, the middle part of the frame shell 51 is a rectangular frame hole, and the two guide rails 71 are disposed on the left and right sides of the rectangular frame hole, and the rollers 73 slide in the rectangular frame hole to roll the second positioning tearing film sheet 52 for film attachment. Among them, the mounting seat 72 is a plastic part, and the mounting seat 72 is mounted on the guide rail 71 through a metal ring 76. The two ends of the roller 73 are rotatably mounted on the mounting seat 72 through bearings 75. A silicone sleeve is provided on the roller 73. The operating handle 74 is used for the film-sticking operator to hold and push the roller 73 to roll the film to ensure that the protective adhesive film is gradually attached to the screen in an inclined manner during film sticking, thereby avoiding the generation of bubbles.
