[0053] Before introducing the film pasting method, the film pasting device of the present invention is first introduced. The film pasting device is used for pasting the film of the membrane assembly.

[0054] Figure 6 The exploded structure diagram of the membrane assembly provided by the embodiment of the present invention is illustrated as follows: Figure 6 As shown, the membrane assembly 40 includes a positioning membrane 41, a protective membrane 42, a dust removal membrane 43 and a pull strip 44, wherein the positioning membrane 41, the protective membrane 42, and the dust removal membrane 43 are sequentially attached, and the pull strip 44 is connected to one end of the dust removal membrane 43 or is integrally formed.

[0055] Figure 1 One of the three-dimensional structural schematic diagrams of the film sticking device provided by an embodiment of the present invention is illustrated. Figure 2 The second schematic diagram of the three-dimensional structure of the film sticking device provided by the embodiment of the present invention is illustrated. Figure 1 and Figure 2 As shown, the film sticking device includes a frame 10, and a first side of the frame 10 has a positioning cavity 11, the positioning cavity 11 is used to accommodate the electronic device 50, and plays a positioning role for the electronic device 50, to prevent the electronic device 50 and the frame 10 from moving relative to each other during the film sticking process, resulting in the misalignment of the applied protective film 42. The size and shape of the positioning cavity 11 are adapted to the size and shape of the electronic device 50. The frame 10 is a rectangular frame, of course, the specific shape of the frame 10 is not limited thereto, and is specifically determined according to the shape of the electronic device 50.

[0056] The second side of the frame 10 is provided with a hollow portion connected to the positioning cavity 11, and the hollow portion is used to make the positioning film 41 extend from the positioning cavity 11 to the second side of the frame 10, thereby realizing the bending installation of the film assembly 40. The hollow portion is provided with a pressing shaft 12 fixedly connected to the frame 10, and the pressing shaft 12 is used to bend the film assembly 40 to the side close to the electronic device 50; the first end of the second side of the frame 10 is provided with a first positioning component 20 for positioning and cooperating with the first end of the positioning film 41; the second end of the second side of the frame 10 is provided with a second positioning component 30 for positioning and cooperating with the second end of the positioning film 41; the positioning film 41 is positioned by the cooperation of the first positioning component 20 and the second positioning component 30, so as to prevent the relative movement of the film assembly 40 and the frame 10 during the film application process, resulting in the misalignment of the applied protective film 42. The frame 10 is provided with a strip hole 19 for the dust removal film 43 and the pull strip 44 to pass through, and the strip hole 19 extends along the width direction of the frame 10.

[0057] When the membrane assembly 40 is fixed in place, pull the pull strip 44 by hand, and the pull strip 44 drives the dust removal film 43 to separate from the protective film 42, and approaches the strip hole 19 along the gap between the protective film 42 and the electronic device 50. Finally, the dust removal film 43 and the pull strip 44 are pulled out of the positioning cavity 11 through the strip hole 19.

[0058] It should be noted that the electronic device 50 in the present invention can be a tablet computer, a mobile phone, an iPad or other electronic devices.

[0059] The film sticking device provided by the embodiment of the present invention arranges the first positioning component 20 and the second positioning component 30 on the second side of the frame 10, and arranges a pressing shaft 12 in the hollow part. After the film component 40 is installed in place, due to the existence of the pressing shaft 12, the film component 40 will bend to the side close to the electronic device 50. During the film sticking process, the bent part first fits with the screen of the electronic device. Under the adsorption force of the protective film 42, the area where the film component 40 fits with the screen of the electronic device gradually expands from the middle to both sides, and finally the film sticking is achieved. During this process, the air between the film component 40 and the screen of the electronic device is evacuated to prevent the formation of bubbles, thereby improving the film sticking effect.

[0060] In the embodiment of the present invention, the frame 10 is made of plastic to reduce the weight of the frame 10. Of course, the frame 10 may also be made of aluminum alloy or other materials. The edges of the frame 10 are rounded to improve the comfort of the user when using the film sticking device.

[0061] In an embodiment of the present invention, Figure 3 The third schematic diagram of the three-dimensional structure of the film sticking device provided by the embodiment of the present invention is illustrated. Figure 3 As shown, the frame 10 includes two long frames and two short frames, and the two long frames cooperate with the two short frames to enclose a positioning cavity 11. The two short frames are respectively referred to as a first short frame and a second short frame, wherein the first short frame is located at the first end of the frame 10, the second short frame is located at the second end of the frame 10, and the strip hole 19 is located at the second short frame, and the strip hole 19 extends along the width direction of the frame 10. The width of the strip hole 19 is greater than or equal to the width of the dust removal film 43, and the height of the strip hole 19 is greater than or equal to the thickness of the dust removal film 43, so that the dust removal film 43 can be pulled out of the positioning cavity 11 by the pull rod 44 through the strip hole 19.

[0062] In an embodiment of the present invention, the first positioning assembly 20 is located at the first short frame, and the first positioning assembly 20 includes at least one first positioning column 21. Specifically, in this embodiment, the first positioning assembly 20 includes two first positioning columns 21, and the two first positioning columns 21 are arranged at intervals along the width direction of the frame 10. The two first positioning columns 21 are arranged at intervals, which can prevent the positioning film 41 from rotating relative to the first positioning column 21 during the positioning process, thereby causing the protective film 42 to be misaligned. The first end of the positioning film 41 is provided with at least one positioning hole, and the number of positioning holes at the first end of the positioning film 41 is the same as the number of the first positioning columns 21, and the position of the first positioning column 21 corresponds to the position of the positioning hole at the first end of the positioning film 41. In another embodiment, the first positioning assembly 20 includes one first positioning column 21. In this case, the first positioning column 21 is a strip positioning column, and the first positioning column 21 extends along the width direction of the frame 10. The use of a strip positioning column can also prevent the first positioning column 21 and the positioning hole at the first end of the positioning film 41 from rotating relative to each other during the positioning and matching process, thereby improving the stability of the film assembly 40. Of course, the number of the first positioning posts 21 is not limited thereto, and may also be three, four or more.

[0063] Furthermore, in order to prevent the first positioning column 21 and the positioning hole at the first end of the positioning membrane 41 from rotating relative to each other during the positioning and matching process, the cross-sectional shape of the first positioning column 21 is the same as that of the positioning hole, and both are non-circular.

[0064] Furthermore, for the same model of membrane assembly 40, the shapes of the positioning holes provided on the positioning membrane 41 may be different due to different manufacturers. In order to adapt to the positioning holes of different positioning membranes 41, the first positioning column 21 is detachably connected to the frame 10. Specifically, the frame 10 is provided with jacks, the number of which is the same as the number of the first positioning columns 21, and the first positioning columns 21 are inserted into the corresponding jacks. When in use, by replacing the first positioning columns 21 with different cross-sectional shapes, the membrane assemblies 40 of different manufacturers can be adapted. Of course, the detachable connection relationship between the first positioning column 21 and the frame 10 is not limited to a plug-in connection, and can also be a screw connection or other detachable connection methods.

[0065] In an embodiment of the present invention, Figure 1 As shown, the second positioning assembly 30 is located at the second short frame, and the second positioning assembly 30 includes at least one second positioning column 31. Specifically, in this embodiment, the second positioning assembly 30 includes two second positioning columns 31, and the two second positioning columns 31 are arranged at intervals along the width direction of the frame 10. The two second positioning columns 31 are arranged at intervals, which can prevent the positioning film 41 and the second positioning columns 31 from rotating relative to each other, thereby causing the protective film 42 to be misaligned. The second end of the positioning film 41 is provided with at least one positioning hole, and the number of positioning holes at the second end of the positioning film 41 is the same as the number of second positioning columns 31, and the position of the second positioning column 31 corresponds to the position of the positioning hole at the second end of the positioning film 41. In another embodiment, the second positioning assembly 30 includes one second positioning column 31. In this case, the second positioning column 31 is a strip positioning column, and the second positioning column 31 extends along the width direction of the frame 10. The use of a strip positioning column can also prevent the second positioning column 31 and the positioning hole at the second end of the positioning film 41 from rotating relative to each other during the positioning and matching process, thereby improving the stability of the film assembly 40. Of course, the number of the first positioning posts 21 is not limited thereto, and may also be three, four or more.

[0066] Furthermore, in order to prevent the second positioning column 31 and the positioning hole at the second end of the positioning membrane 41 from rotating relative to each other during the positioning and matching process, the cross-sectional shape of the second positioning column 31 is the same as that of the positioning hole, and both are non-circular.

[0067] Further, in order to adapt to the positioning holes of different positioning films 41, the second positioning column 31 is detachably connected to the frame 10. Specifically, the frame 10 is provided with jacks, the number of which is the same as the number of the second positioning columns 31, and the second positioning columns 31 are inserted into the corresponding jacks. When in use, by replacing the second positioning columns 31 with different cross-sectional shapes, the membrane assemblies 40 of different manufacturers can be adapted. Of course, the detachable connection relationship between the second positioning column 31 and the frame 10 is not limited to a plug-in connection, and can also be a screw connection or other detachable connection methods.

[0068] In the embodiment of the present invention, the first positioning assembly 20 includes two first positioning posts 21, and the second positioning assembly 30 includes two second positioning posts 31, and the cross-sectional shapes of the two first positioning posts 21 are different. During the installation of the membrane assembly 40, if the membrane assembly 40 is placed incorrectly, the two positioning holes at the first end of the positioning membrane 41 cannot be positioned and matched with the two first positioning posts 21 due to the different cross-sectional shapes of the two first positioning posts 21. Similarly, when the cross-sectional shapes of the two second positioning posts 31 are different, the two positioning holes at the second end of the positioning membrane 41 cannot be positioned and matched with the two second positioning posts 31. Only after the membrane assembly 40 is accurately placed in place can the positioning posts be positioned and matched with the corresponding positioning holes.

[0069] In the embodiment of the present invention, the first end of the second side of the frame 10 is provided with a first limiting groove 13, and the first positioning column 21 is located in the first limiting groove 13. Specifically, the first positioning column 21 is located at the bottom wall of the first limiting groove 13. The first limiting groove 13 is used to limit the first end of the positioning film 41 to prevent the positioning film 41 from moving along the width direction of the frame 10. Through the cooperation of the first limiting groove 13 and the first positioning column 21, the positioning film 41 can be limited from multiple directions, which can effectively prevent the positioning film 41 from moving, and improve the stability of the film assembly 40 during the film application process.

[0070] In an embodiment of the present invention, Figure 1 As shown, a second limiting groove 14 is provided at the second end of the second side of the frame 10, and a second positioning column 31 is located in the second limiting groove 14. Specifically, the second positioning column 31 is located at the bottom wall of the second limiting groove 14. The second limiting groove 14 is used to limit the second end of the positioning film 41 to prevent the positioning film 41 from moving along the width direction of the frame 10. The second limiting groove 14 cooperates with the second positioning column 31 to limit the positioning film 41 from multiple directions, effectively preventing the positioning film 41 from moving, and further improving the stability of the film assembly 40 during the film application process.

[0071] In an embodiment of the present invention, the pressing shaft 12 is arranged along the width direction of the frame 10, and the pressing shaft 12 has a contact portion for abutting against the positioning film 41 on the side facing the positioning cavity 11, and the contact portion is used to contact the membrane assembly 40 so that the membrane assembly 40 is bent toward the side close to the electronic device 50. The distance between at least one of the bottom wall of the first limiting groove 13 and the bottom wall of the second limiting groove 14 and the plane where the contact portion is located is greater than or equal to 0.1 cm, and less than or equal to 1.5 cm. It should be noted here that when the contact portion is provided with an elastic pressure strip, the distance here refers to the distance between the elastic pressure strip facing the electronic device and the bottom wall of the limiting groove is greater than or equal to 0.1 cm, and less than or equal to 1.5 cm. The size of the above distance determines the degree of bending of the film assembly 40. When the distance is greater than 1.5 cm, the film assembly 40 will bend too much, causing the protective film 42 to separate from the dust removal film 43, causing dust in the air to enter the protective film, and even causing the protective film to dry, making it impossible to implement normal film sticking; when the distance is less than 0.1 cm, the protective film 42 will not be able to expel air well during the bonding process of the electronic device screen, resulting in poor film sticking effect.

[0072] In the embodiment of the present invention, the contact portion is provided with an elastic strip extending along the length direction of the pressing shaft 12. The elastic strip is made of sponge, rubber, silicone or other flexible materials, and the elastic strip is used to contact the membrane assembly 40 to avoid wear on the membrane assembly 40.

[0073] In an embodiment of the present invention, Figure 2 As shown, the contact portion is provided with a groove 15, and the elastic pressure strip is embedded in the groove 15. In order to ensure that the elastic pressure strip is in good contact with the membrane assembly 40, the elastic pressure strip protrudes relative to the edge of the groove 15.

[0074] In an embodiment of the present invention, a third limiting groove 16 is provided at the first end of the second side of the frame 10, and specifically, the third limiting groove 16 is located at the first short frame. The third limiting groove 16 is located at the side of the first limiting groove 13 close to the pressing shaft 12, the first limiting groove 13 is connected to the third limiting groove 16, and a step is formed between the first limiting groove 13 and the third limiting groove 16. The third limiting groove 16 is used to limit the first end of the dust removal film 43. After the film assembly 40 is installed in place, the first end of the dust removal film 43 abuts against the third limiting groove 16. The dust removal film 43 is limited by the third limiting groove 16, which further improves the stability of the film assembly 40 and prevents the protective film 42 from shifting during the film application process.

[0075] In the embodiment of the present invention, a plurality of positioning protrusions 17 are arranged at intervals on the side wall of the positioning cavity 11. After the electronic device 50 is inserted into the positioning cavity 11, the positioning protrusions 17 abut against the electronic device 50, so that there is a gap between the electronic device 50 and the inner wall of the positioning cavity 11, which facilitates the removal of the electronic device 50 after the film is applied.

[0076] In an embodiment of the present invention, a flexible coating is provided on the surface of the positioning protrusion 17. Specifically, the flexible coating can be applied to the surface of the positioning protrusion 17. The flexible coating can prevent the positioning protrusion 17 from directly contacting the electronic device housing and causing scratches on the housing surface. The material of the flexible coating is rubber or silicone.

[0077] In the embodiment of the present invention, the pressing shaft 12 divides the hollow portion into two openings 18 , and the widths of the two openings 18 are both greater than the width of the positioning film 41 , so as to facilitate the film assembly 40 to extend out of the positioning cavity 11 through the openings 18 .

[0078] In an embodiment of the present invention, Figure 4 The schematic diagram of the main structure of the film sticking device provided by the embodiment of the present invention with the film assembly installed is illustrated. Figure 5 is along Figure 4 The side view section structure diagram made by the section line AA in the figure is as follows: Figure 4 and Figure 5 As shown, the pressure shaft 12 is connected to the middle of the long frame, and the pressure shaft 12 is perpendicular to the long frame. The position of the pressure shaft 12 determines the position where the film assembly 40 bends. By setting the pressure shaft 12 in the middle of the frame 10, the middle of the protective film 42 can be attached to the electronic device screen, and the area where the film assembly 40 attaches to the electronic device screen gradually expands from the middle to both sides. Of course, the pressure shaft 12 and the long frame may not be perpendicular, and the pressure shaft 12 and the long frame form an acute angle, and the acute angle is greater than 45°.

[0079] In the embodiment of the present invention, the pressure shaft 12 is an elastic pressure shaft, that is, the pressure shaft 12 is made of elastic material. After the pull strip 44 is pulled out, the pressure shaft can be pressed by hand to make the film assembly 40 easier to bend and more convenient to fit with the electronic device screen.

[0080] Combine the following Figure 7-Figure 10 The film attaching method according to the embodiment of the present invention is described.

[0081] Figure 8 One of the flowcharts provided by the embodiment of the present invention is illustrated, such as Figure 8 As shown, the film pasting method is based on the film pasting device in the above embodiment to paste the film, the film pasting device includes a frame 10, and the frame 10 is provided with a first positioning component 20, a second positioning component 30 and a pressing shaft 12; the film pasting method includes:

[0082] Step S100, positioning the film assembly 40 by the first positioning assembly 20 and the second positioning assembly 30, so that the film assembly 40 is bent toward a side close to the electronic device 50 under the action of the pressing shaft 12;

[0083] Since the first positioning component 20 and the second positioning component 30 are both located on the second side of the frame 10, the side of the pressing shaft 12 facing the positioning cavity 11 protrudes relative to the first positioning component 20 and the second positioning component 30. Therefore, after the membrane assembly 40 is installed in place, the membrane assembly 40 is bent toward the side close to the electronic device 50 under the action of the pressing shaft 12, that is, the middle part of the membrane assembly 40 is arched toward the side facing the screen of the electronic device.

[0084] Step S200, installing the electronic device 50 into the positioning cavity 11 of the frame 10;

[0085] In step S300, the dust removal film 43 is moved to the outside of the positioning cavity 11 by using the pull strip 44 so that the middle of the protective film 42 fits with the electronic device screen; under the adsorption force of the protective film 42, the fitting area between the protective film 42 and the electronic device screen spreads to the surroundings.

[0086] After removing the dust removal film 43, the middle part of the protective film 42 fits with the screen of the electronic device. Since the protective film 42 itself has adsorption force, after the middle part of the protective film 42 fits with the screen of the electronic device, under the action of the adsorption force and the elastic force of the protective film 42, the protective film 42 in other areas approaches the screen of the electronic device under the action of the adsorption force, thereby achieving the spreading of the bonding area between the protective film 42 and the screen of the electronic device to the surrounding areas, and finally the protective film 42 is completely bonded to the screen of the electronic device.

[0087] It should be noted that the protective film 42 in this embodiment is a tempered film, but it can also be other types of protective films.

[0088] The film pasting method provided by the embodiment of the present invention positions the film assembly 40 by using the first positioning component 20 and the second positioning component 30, and bends the film assembly 40 to the side close to the electronic device 50 by the pressing shaft 12; when the dust removal film 43 is moved to the outside of the positioning cavity 11, the bent part of the protective film 42 first fits with the screen of the electronic device, and under the adsorption force of the protective film 42, the area where the film assembly 40 fits with the screen of the electronic device gradually expands from the middle to both sides, and finally the film pasting is achieved. In this process, the air between the film assembly 40 and the screen of the electronic device is evacuated to prevent the formation of bubbles, thereby improving the film pasting effect.

[0089] In an embodiment of the present invention, after the step of moving the dust removal film 43 to the outside of the positioning cavity 11 by using the pull rod 44, the film attaching method further includes:

[0090] In step S400 , pressure is applied to the membrane assembly 40 via the pressure shaft 12 .

[0091] For the protective film 42 with insufficient adsorption force, the pressing shaft 12 can be pressed by hand to bend the pressing shaft 12 toward the electronic device screen. During this process, the pressing shaft 12 squeezes the side of the positioning film 41 away from the protective film 42, so that the side of the protective film 42 away from the positioning film 41 fits with the electronic device screen.

[0092] Furthermore, in the process of applying pressure to the film assembly 40 through the pressing shaft 12, it is necessary to ensure that the pressure applied to each part of the film assembly 40 is equal, so that the width of the protective film 42 is first the same as the width of the bonding area of ​​the electronic device screen, and in the subsequent process of bonding the protective film 42 to the electronic device screen by relying on the adsorption force, the bonding rate at any point along the width direction of the protective film 42 is the same, and the rhythm of air discharge at any point is the same, which effectively prevents different air discharge rates in different areas, causing part of the air to be trapped between the protective film 42 and the electronic device screen to form bubbles.

[0093] In an embodiment of the present invention, the steps of positioning the membrane assembly 40 by the first positioning assembly 20 and the second positioning assembly 30 include:

[0094] Step S110, positioning the positioning hole at the first end of the positioning film 41 and the first positioning assembly 20;

[0095] Step S120 , positioning the positioning hole at the second end of the positioning film 41 and the second positioning assembly 30 .

[0096] By positioning the film assembly 40 through two sets of positioning components, it is possible to prevent the film assembly 40 from moving during the film application process, thereby preventing the protective film 42 from being misaligned with the electronic device screen, thereby improving the film application effect.

[0097] In an embodiment of the present invention, before the step of installing the electronic device 50 into the positioning cavity 11 of the frame 10, the film attaching method further includes:

[0098] One end of the pull bar 44 away from the first positioning assembly 20 extends out from the bar-shaped hole 19 .

[0099] The purpose of extending the end of the pull bar 44 away from the first positioning component 20 from the strip hole 19 is to facilitate the subsequent manual pulling of the pull bar 44. Of course, the above step can also be performed simultaneously with the step of installing the electronic device 50 into the positioning cavity 11 of the frame 10.

[0100] It should be noted that the location of the strip hole 19 determines the direction in which the pull-out strip 44 is pulled out. In this embodiment, the strip hole 19 is located in the second short frame, so the pull-out direction of the pull-out strip 44 is the direction away from the first short frame, that is, Figure 4 When the strip hole 19 is located in one of the long frames, the pulling direction of the pull bar 44 is away from the other long frame, that is, Figure 4 In the upward direction or the downward direction.

[0101] Fig. 9 The second flowchart provided by the embodiment of the present invention is illustrated below. Fig. 9 A specific embodiment of the present invention is described as follows. Fig. 9 As shown, the film pasting method includes the following steps:

[0102] Step S100, positioning the film assembly 40 by the first positioning assembly 20 and the second positioning assembly 30, so that the film assembly 40 is bent toward a side close to the electronic device 50 under the action of the pressing shaft 12;

[0103] Step S200, installing the electronic device 50 into the positioning cavity 11 of the frame 10;

[0104] Step S300, using the pull bar 44 to move the dust removal film 43 to the outside of the positioning cavity 11, so that the middle of the protective film 42 is in contact with the electronic device screen; under the adsorption force of the protective film 42, the contact area between the protective film 42 and the electronic device screen spreads to the surroundings;

[0105] In step S400 , pressure is applied to the membrane assembly 40 via the pressure shaft 12 .

[0106] In one embodiment of the present invention, Figure 1 As shown, the first positioning component 20 includes two first positioning columns 21. Therefore, in the process of performing the step of positioning and matching the positioning hole at the first end of the positioning membrane 41 with the first positioning component 20, it is only necessary to sleeve the first positioning column 21 into the positioning hole at the first end of the positioning membrane 41. Compared with the simple positioning method of clamping with a clamp, the positioning step is simplified.

[0107] In an embodiment of the present invention, Figure 7 The exploded structure diagram of the film sticking device provided by another embodiment of the present invention is illustrated as follows: Figure 7 As shown, the first positioning assembly 20 includes a pressure rod 22, and at least one first positioning column 21 is arranged in the middle of the pressure rod 22; the first end of the pressure rod 22 is hinged to the first end of the second side of the frame 10, specifically, the first end of the pressure rod 22 is hinged to the first short frame. Two first positioning columns 21 are arranged at intervals in the middle of the pressure rod 22, and the two first positioning columns 21 are arranged at intervals along the length direction of the pressure rod 22, and the positions of the first positioning columns 21 correspond to the positions of the positioning holes at the first end of the positioning film 41. A second latch 26 is arranged at the second end of the pressure rod 22, and a second slot 27 is arranged at the first end of the second side of the frame 10, that is, the first short frame is provided with a second slot 27; the second latch 26 is connected by a snap connection with the second slot 27. A positioning blind hole 23 is arranged at the first end of the second side of the frame 10, and the position of the positioning blind hole 23 corresponds to the position of the first positioning column 21.

[0108] The step of positioning the positioning hole at the first end of the positioning film 41 and the first positioning assembly 20 comprises:

[0109] Step S111, separating the second end of the pressing rod 22 from the frame 10;

[0110] Specifically, the second end of the pressing rod 22 is pulled manually to separate the second latching tongue 26 from the second latching groove 27 , thereby separating the second end of the pressing rod 22 from the frame 10 .

[0111] Step S112, placing the first end of the positioning film 41 into the first limiting groove 13 for limiting;

[0112] After the first end of the positioning film 41 is placed in the first limiting groove 13, since the first limiting groove 13 limits the first end of the positioning film 41, the position of the first positioning column 21 will correspond one-to-one to the position of the positioning hole at the first end of the positioning film 41, and there is no need to manually adjust the position of the positioning film 41.

[0113] Step S113 , pressing the second end of the pressing rod 22 to insert the first positioning column 21 into the corresponding positioning hole, and making the second end of the pressing rod 22 engage with the frame 10 .

[0114] After pressing the second end of the pressure rod 22, the second latch tongue 26 is connected with the second latch groove 27. At this time, the first positioning column 21 is inserted into the corresponding positioning hole, and part of the first positioning column 21 is embedded in the positioning blind hole 23, so as to realize the positioning of the first end of the positioning membrane 41.

[0115] In an embodiment of the present invention, the step of moving the dust removal film 43 to the outside of the positioning cavity 11 by using the pull rod 44 includes:

[0116] Step S310, pulling the end of the pull bar 44 away from the first positioning assembly 20 to move in a direction away from the frame 10 at a first rate, so that the end of the pull bar 44 close to the first positioning assembly 20 passes between the pressing shaft 12 and the screen of the electronic device;

[0117] Since the distance between the pressing shaft 12 and the electronic device screen is very small, in order to ensure that the connection between the pull rod 44 and the dust removal film 43 passes smoothly between the dust removal film 43 corresponding to the pressing shaft 12 and the electronic device screen, the pull rod 44 needs to be pulled at a relatively low speed. Figure 4As shown, in the area on the left side of the pressing shaft 12, the end of the pull bar 44 away from the first positioning assembly 20 is pulled to the right at a first rate, and the left side of the dust removal film 43 moves to the right at the same rate until the connection between the pull bar 44 and the dust removal film 43 passes through the pressing shaft 12. Since the connection between the pull bar 44 and the dust removal film 43 is connected by bonding, passing through the pressing shaft 12 at a lower rate can avoid the connection between the pull bar 44 and the dust removal film 43 from being separated, and can also avoid deformation of the protective film 42 at the connection with the electronic device screen, thereby ensuring the flatness of the protective film 42.

[0118] Step S320, pulling the end of the pull bar 44 away from the first positioning assembly 20 at a second rate to move away from the frame 10, so as to drive the dust removal film 43 to move to the outside of the positioning cavity 11 through the strip hole 19, wherein the second rate is greater than the first rate.

[0119] After the connection between the pull rod 44 and the dust removal film 43 passes through the pressing shaft 12 , the pull rod 44 is pulled at a relatively high speed due to no obstruction, so that the dust removal film 43 moves quickly to the outside of the positioning cavity 11 .

[0120] It should be noted that, in order to prevent the dust removal film 43 from being deflected during removal, the moving direction of the pull bar 44 is perpendicular to the width direction of the dust removal film 43 .

[0121] In an embodiment of the present invention, before the step of positioning the film assembly 40 by the first positioning assembly 20 and the second positioning assembly 30, the film attaching method further includes:

[0122] Step S90, cleaning the screen of the electronic device.

[0123] By cleaning the electronic device screen, dust, bacteria and other fine particles on the electronic device screen can be eliminated, and bubbles caused by the presence of fine particles in subsequent film application can be avoided, ensuring that the protective film 42 can be effectively attached to the electronic device screen, thereby improving the film application effect.

[0124] Fig.10 The third flowchart provided by the embodiment of the present invention is illustrated below. Fig.10 A specific embodiment of the present invention is described as follows. Fig.10 As shown, the film pasting method includes:

[0125] Step S90, cleaning the screen of the electronic device;

[0126] Step S100, positioning the film assembly 40 by the first positioning assembly 20 and the second positioning assembly 30, so that the film assembly 40 is bent toward a side close to the electronic device 50 under the action of the pressing shaft 12;

[0127] Step S200, installing the electronic device 50 into the positioning cavity 11 of the frame 10;

[0128] Step S300, using the pull bar 44 to move the dust removal film 43 to the outside of the positioning cavity 11, so that the middle of the protective film 42 is in contact with the electronic device screen; under the adsorption force of the protective film 42, the contact area between the protective film 42 and the electronic device screen spreads to the surroundings;

[0129] In step S400 , pressure is applied to the membrane assembly 40 via the pressure shaft 12 .

[0130] In an embodiment of the present invention, the step of cleaning the screen of an electronic device includes:

[0131] Step S91, wiping the screen of the electronic device with a cleaning cotton with a cleaning agent;

[0132] The screen of the electronic device is wiped with a cleaning cotton with a cleaning agent, and the cleaning agent can dissolve the dirt on the screen of the electronic device, thereby enhancing the cleaning effect. In this embodiment, the cleaning agent is alcohol, and of course, it can also be a cleaning agent with the same function.

[0133] Step S92, wiping the screen of the electronic device with dry cleaning cotton.

[0134] Using dry cleaning cotton to wipe the screen of an electronic device can not only remove residual detergent on the screen of the electronic device to prevent the detergent from damaging the screen due to staying on the screen surface for a long time; it can also perform secondary cleaning on the remaining fine particles to further enhance the cleaning effect.

[0135] In an embodiment of the present invention, after the step of wiping the screen of the electronic device with dry cleaning cotton, the step of cleaning the screen of the electronic device further includes:

[0136] Step S93, using a sticky dust removal sticker to absorb dust on the screen of the electronic device.

[0137] Using sticky dust removal stickers to absorb dust on the screen of electronic devices can avoid bubbles caused by the presence of dust in subsequent film application.
