The following describes the film sticking device according to the embodiment of the utility model in conjunction with FIGS. 1 to 7 .

The film pasting device of the present invention includes a frame 10 and a limiting assembly 60. The film pasting device of this embodiment is used for pasting films on a film assembly 40. As shown in FIG. 7 , the film assembly 40 includes a positioning film 41, a protective film 42, a dust removal film 43 and a pull strip 44, wherein the positioning film 41, the protective film 42 and the dust removal film 43 are sequentially pasted, and the pull strip 44 is connected to one end of the dust removal film 43 or is integrally formed.

As shown in FIGS. 1 and 2 , the first side of the frame 10 has a positioning cavity 11, which is used to accommodate the electronic device 50 and to position the electronic device 50, so as to prevent the electronic device 50 and the frame 10 from moving relative to each other during the film application process, thereby causing the applied protective film 42 to be misaligned. The size and shape of the positioning cavity 11 are adapted to the size and shape of the electronic device 50. In this embodiment, the frame 10 is a rectangular frame, but of course, the shape of the frame 10 is not limited thereto, and is specifically determined according to the shape of the electronic device 50.

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 allow the positioning film 41 to 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 first end of the second side of the frame 10 is provided with a first positioning assembly 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 assembly 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 assembly 20 and the second positioning assembly 30 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. As shown in FIG. 4 , the frame 10 is provided with a strip hole 12 for the dust removal film 43 and the pull strip 44 to pass through, and the strip hole 12 extends along the width direction of the frame 10.

The limiting assembly 60 is disposed in the hollow portion, and the limiting assembly 60 has a working portion 62 , and the working portion 62 is used to bend the membrane assembly 40 toward a side close to the electronic device 50 .

After the film assembly 40 is fixed in place, the pull strip 44 is pulled 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 12 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 12, and then the part of the film assembly 40 that cooperates with the working part 62 is bent toward the side close to the electronic device 50 through the working part 62. Under the elastic action of the protective film 42, the area where the film assembly 40 is attached to the screen of the electronic device 50 gradually expands to both sides, and finally the film is attached.

It should be noted that the electronic device 50 in the present invention may be a tablet computer, a mobile phone or other electronic devices.

The film sticking device provided by the embodiment of the utility model arranges the first positioning component 20 and the second positioning component 30 on the second side of the frame 10, and arranges a limiting component 60 in the hollow part. After the film component 40 is installed in place, the film component 40 is pressed by the working part 62 of the limiting component 60, so that the film component 40 is bent toward the side close to the electronic device 50 and fits with the screen of the electronic device 50, and the air in the fitting area is discharged. Under the elastic action of the protective film 42, the area where the film component 40 and the screen of the electronic device 50 are fitted gradually expands toward the edge. In this process, the air between the film component 40 and the screen of the electronic device 50 is automatically driven away to prevent the formation of bubbles, thereby improving the film sticking effect.

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 can 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.

In the embodiment of the utility model, the frame 10 includes two long frames and two short frames, and the two long frames cooperate with the two short frames to enclose the positioning cavity 11. The two short frames are respectively referred to as the first short frame and the 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 12 is located at the second short frame, and the strip hole 12 extends along the width direction of the frame 10. The width of the strip hole 12 is greater than or equal to the width of the dust removal film 43, and the thickness of the strip hole 12 is greater than or equal to the thickness of the dust removal film 43.

In one embodiment of the utility model, as shown in Figures 1 to 3, the limiting assembly 60 includes a pressing shaft 63, which is located in the hollow part and fixedly connected to the frame 10. A working hole 631 is opened on the pressing shaft 63, and the working hole 631 extends along the width direction of the frame 10. The working hole 631 forms a working part 62. The finger presses the film assembly 40 through the working hole 631 and can move in the working hole 631 along the width direction of the frame 10, so that the film assembly 40 is bent toward the side close to the electronic device 50. The bent part during the film pasting process first fits with the screen of the electronic device 50. Under the elastic action of the protective film 42, the area where the film assembly 40 and the screen of the electronic device 50 are pasted gradually expands from the middle to both sides, so that the air between the film assembly 40 and the screen of the electronic device 50 is driven away, and finally the film pasting is achieved.

In an embodiment of the present utility model, as shown in FIG. 3 , the cross section of the working hole 631 may be a long strip, and the length direction of the working hole 631 extends along the width direction of the frame 10 ; of course, as shown in FIG. 5 , the working hole 631 may also be a rectangle.

In an embodiment of the utility model, the side of the pressing shaft 63 facing the positioning cavity 11 has an elastic strip 64, and the elastic strip 64 is made of sponge, rubber, silicone or other flexible materials. The elastic strip 64 is in contact with the membrane assembly 40 to avoid wear on the membrane assembly 40.

In another embodiment of the utility model, as shown in FIG6 , the limit assembly 60 includes at least one limit member 61 connected to the long frame. In this embodiment, the limit assembly 60 includes two limit members 61, the first ends of the two limit members 61 are connected to the middle parts of the two long frames one by one, the second ends of the two limit members 61 are arranged opposite to each other, and there is a distance between the second ends of the two limit members 61, so that a working portion 62 is formed between the second ends of the two limit members 61, and when the film assembly 40 is fixed in place and the dust removal film 43 and the pull strip 44 are pulled out of the positioning cavity 11 through the strip hole 12, the finger presses the protective film 42 through the working portion 62 between the two limit members 61, so that the protective film 42 bends to the side close to the electronic device 50, and under the elastic action of the protective film 42, the film assembly 40 fits the screen of the electronic device 50. It should be noted that when the limiting assembly 60 includes a pressing shaft 63, the middle portion of the pressing shaft 63 can be cut off so that the remaining portion serves as two limiting members 61, and the cut-off portion is hollowed out to form a working portion 62, which can reduce costs.

In an embodiment of the present utility model, the limiting assembly 60 also includes an elastic strip arranged between the second ends of the two limiting members 61, and the elastic strip is located on the side facing the positioning cavity 11, and contacts the membrane assembly 40 through the elastic strip 64 to avoid wear on the membrane assembly 40.

In an embodiment of the utility model, the first positioning assembly 20 is located in 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.

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.

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.

In an embodiment of the utility model, the second positioning assembly 30 is located in 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.

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.

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.

In the embodiment of the utility model, 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. In the process of installing 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.

In the embodiment of the utility model, 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.

In the embodiment of the utility model, the second end of the second side of the frame 10 is provided with a second limiting groove 14, and the 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. Through the cooperation of the second limiting groove 14 and the second positioning column 31, the positioning film 41 can be limited 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.

In an embodiment of the utility model, 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 on the side of the first limiting groove 13 close to the pressing shaft 63, 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.

In an embodiment of the present utility model, as shown in FIG5 , a plurality of positioning protrusions 17 are provided 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.

In the embodiment of the present invention, the surface of the positioning protrusion 17 is provided with a flexible coating. 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 housing of the electronic device 50, causing scratches on the housing surface. The material of the flexible coating is rubber or silicone.

In an embodiment of the present invention, as shown in FIG. 3 , the pressing shaft 63 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 .

In the embodiment of the utility model, the pressure shaft 63 is connected to the middle of the long frame, and the pressure shaft 63 is perpendicular to the long frame. The position of the pressure shaft 63 determines the position where the film assembly 40 bends. By setting the pressure shaft 63 in the middle of the frame 10, the middle of the protective film 42 can be first attached to the screen of the electronic device 50, and the area where the film assembly 40 and the screen of the electronic device 50 are attached gradually expands from the middle to both sides. Of course, the pressure shaft 63 and the long frame may not be perpendicular, and the pressure shaft 63 and the long frame are at an acute angle, and the acute angle is greater than 45°.

In the embodiment of the utility model, the pressing shaft 63 is an elastic pressing shaft, that is, the pressing shaft 63 is made of elastic material. After the pull strip 44 is pulled out, the film assembly 40 can be pressed by passing a finger through the working hole 631 to bend the film assembly 40 to achieve adhesion with the screen of the electronic device 50.
