[0050] Example 2

[0051] See also Figures 1 to 6 In this embodiment, a film sticking box 10 has a receiving groove 111 inside the film sticking box 10;

[0052] The receiving groove 111 is used to fix the electronic device 30 and the film assembly 20;

[0053] The film assembly 20 includes a first release film 21, a protective film 22, and a second release film 23 which are stacked in sequence. A tear strip 24 is connected to one end of the second release film 23. The tear strip 24 is stacked and arranged on the side of the second release film 23 away from the protective film 22. A film outlet 117 connected to the receiving groove 111 is arranged at one end of the film box 10. The film outlet 117 is used to allow the tear strip 24 to extend from the receiving groove 111 to the outside of the film box 10.

[0054] The bottom of the receiving groove 111 is provided with a positioning assembly and a first groove 113;

[0055] The positioning assembly is disposed on the periphery of the first groove 113 and is used to fix the first release film 21 ; the first groove 113 is used to fix the protective film 22 and the second release film 23 .

[0056] When in use, the film assembly 20 is placed in the receiving groove 111. Figure 2 As shown, the connection between the second release film 23 and the tear strip 24 of the film assembly 20 is placed away from the film outlet 117, the first release film 21 of the film assembly 20 is fixed on the positioning assembly of the receiving groove 111, the protective film 22 and the second release film 23 are fixed in the first groove 113 of the receiving groove 111, and the tear strip 24 passes through the film outlet 117, and the tear strip 24 extends from the receiving groove 111 to the outside of the film box 10. Figure 4 As shown, the electronic device 30 is placed in the receiving groove 111, and the tear strip 24 outside the film sticking box 10 is pulled to gradually separate the second release film 23 connected by the tear strip 24 from the protective film 22, and at the same time, a pressure is applied to the electronic device 30 to press the bottom of the receiving groove 111, so that the adhesive surface 22a of the protective film 22 is exposed and then stuck to the electronic device 30. After the sticking is completed, the electronic device 30 is taken out, and the first release film 21 on the side of the protective film 22 away from the adhesive surface 22a is torn off, and the film sticking of the electronic device 30 is completed.

[0057] In the film box 10 configured in this way, the positioning component and the first groove 113 can fix the film component 20, and the receiving groove 111 can fix the electronic device 30, so that the film component 20 and the electronic device 30 are relatively fixed, and the electronic device 30 and the protective film 22 can be accurately aligned; moreover, the electronic device 30 is placed above the film component 20, and after pulling out the tear strip 24, the adhesive surface 22a of the protective film 22 is located between the electronic device 30 and the bottom of the receiving groove 111, which can effectively prevent dust from entering from above between the electronic device 30 and the adhesive surface 22a of the protective film 22, reduces the probability of dust entering and bubbles generating between the protective film 22 and the electronic device 30, improves the success rate and efficiency of film pasting of the electronic device 30, reduces the waste of the film component 20, and reduces the film pasting cost.

[0058] Furthermore, if Figure 3As shown, the positioning assembly includes a plurality of first protrusions 112 , each of which is spaced apart and distributed around the first groove 113 , and the first protrusions 112 are used to penetrate the positioning holes 211 of the first release film 21 .

[0059] The positioning assembly configured in this way can quickly fix the first release film 21 , and limit the movement of the first release film 21 in a direction parallel to the bottom of the receiving groove 111 .

[0060] The first protrusion 112 may be provided on one or more sides of the circumferential side of the first groove 113 .

[0061] When the first protrusion 112 is arranged on one side of the first groove 113, the first protrusion 112 is arranged at the end of the receiving groove 111 away from the film outlet 117, so that the end of the first release film 21 away from the film outlet 117 is fixed, and the stability of the first release film 21 can be ensured when the tear strip 24 is pulled.

[0062] The first protrusions 112 are preferably arranged on two opposite sides of the first groove 113. This arrangement can save the number of first protrusions 112 to be assembled and reduce production costs; on the other hand, compared with only being arranged on one side of the first groove 113, the first protrusions 112 arranged on two opposite sides of the first groove 113 can make the first release film 21 more firmly fixed and prevent the first release film 21 from shifting.

[0063] Furthermore, if Figure 2 As shown, the plurality of first protrusions 112 are asymmetrically disposed on opposite sides of the first groove 113 .

[0064] The asymmetric design realizes an anti-mistake function. A positioning hole 211 matching the first protrusion 112 is provided on the film assembly 20. The asymmetric design guides the user to install the film assembly 20 in a specific direction so that the tear strip 24 passes through the film outlet 117 from the correct direction, effectively preventing the film assembly 20 from being installed in reverse.

[0065] It should be known that there are many ways to achieve an asymmetric design of the multiple first protrusions 112. The multiple first protrusions 112 may have the same shape and size, and the number of the multiple first protrusions 112 disposed on the opposite sides of the first groove 113 may be different, and the asymmetric design is achieved by distributing different numbers of the first protrusions 112; the multiple first protrusions 112 may have different shapes and sizes, and the asymmetric design is achieved by different shapes of the first protrusions 112.

[0066] Furthermore, if Figure 2 As shown, the positioning assembly includes at least two first protrusions 112 with different shapes.

[0067] As an example, in the present embodiment, two first protrusions 112 are respectively provided on the two opposite sides of the first groove 113, wherein one of the first protrusions 112 is in the shape of an elliptical cylinder, and the remaining first protrusions 112 are in the same cylindrical shape. The different shapes of the first protrusions 112 realize an asymmetric design of the positioning component, which can effectively guide the user to install the film component 20 in a specific direction.

[0068] Furthermore, if Figure 2 and 7 As shown, at least one second protrusion 118 is disposed at the bottom of the first groove 113 , and the height of each second protrusion 118 is less than or equal to the depth of the first groove 113 .

[0069] It should be understood that pulling out the tear strip 24 and applying pressure to the bottom of the first groove 113 to the electronic device 30, so that the electronic device 30 is pressed onto the protective film 22 with the adhesive surface 22a exposed, has a great impact on the quality and efficiency of film pasting when performing the above operation. On the one hand, since the user usually presses the electronic device 30 directly by hand, or presses the cover 12 provided on the film pasting box 10 to apply regional pressure to the electronic device 30, the pressure on the electronic device 30 and the protective film 22 is uneven, and the travel of the electronic device 30 to the bottom of the first groove 113 after being subjected to force is inconsistent, resulting in that part of the electronic device 30 is not completely pressed onto the protective film 22; on the other hand, when the tear strip 24 is pulled out, it is usually necessary to separate the second release film 23 from the protective film 22 at the connection with the tear strip 24 first, but the protective film 22 here often moves with the pulling of the tear strip 24, making it difficult to separate the second release film 23 from the protective film 22. The above two aspects affect the quality and efficiency of film pasting.

[0070] In this embodiment, a second protrusion 118 is provided at the bottom of the first groove 113. The second protrusion 118 can be provided in the first groove 113 corresponding to an area where the electronic device 30 and the protective film 22 are not easy to fit together, such as the edge of the bottom of the first groove 113, thereby reducing the travel required for a partial area of ​​the electronic device 30 to abut against the bottom of the first groove 113, so that the electronic device 30 and the protective film 22 are better fitted in the area where they are not easy to fit together, reducing the probability of bulging and edge warping of the protective film 22 after being attached to the electronic device 30, and improving the quality of the film.

[0071] Furthermore, if Figure 2 and 7 As shown, at least one second protrusion 118 is disposed at one end of the first groove 113 close to the film outlet 117 .

[0072] One end of the first groove 113 close to the film outlet 117 corresponds to the area where the second release film 23 and the protective film 22 are finally separated. The second protrusion 118 is arranged here to efficiently separate the second release film 23 and the protective film 22, thereby avoiding the warping of the part where the protective film 22 and the second release film 23 are finally separated, thereby improving the film pasting quality and efficiency.

[0073] Furthermore, if Figure 7 As shown, the groove wall height of the first groove 113 at the end away from the film outlet 117 is greater than the groove wall height of the first groove 113 close to the film outlet 117. The peripheral side of the first groove 113 away from the film outlet 117 is used to support the connection between the tear strip 24 and the second release film 23.

[0074] like Figure 7 As shown, the height of the groove wall of the first groove 113 at the end away from the film outlet 117 differs from the height of the groove wall of the first groove 113 at the end close to the film outlet 117 by h.

[0075] The peripheral side of the first groove 113 away from the film outlet 117 corresponds to the area where the second release film 23 and the protective film 22 are first separated. In the direction from the end of the film outlet 117 on the film sticking box 10 to the film outlet 117, the groove wall height of the first groove 113 is different and tends to decrease, which can enable the second release film 23 and the protective film 22 to separate quickly and prevent the protective film 22 from moving with the second release film 23, thereby effectively improving the film sticking efficiency.

[0076] Furthermore, if Figure 2 and 4 As shown, a protrusion 114 is provided at the connection between two adjacent groove walls of the receiving groove 111 , and a clamping portion 114 a is provided at the corner of the protrusion 114 facing the center of the receiving groove 111 . The clamping portions 114 a of the plurality of protrusions 114 are used to limit the electronic device 30 .

[0077] Furthermore, if Figure 2 and 4 As shown, on a projection surface parallel to the depth direction of the receiving groove 111 , each protrusion 114 is concave in an arc shape at a corner toward the center of the receiving groove 111 .

[0078] like Figure 4 As shown, when the electronic device 30 is assembled into the receiving groove 111, the protrusions 114 at the four corners of the receiving groove 111 can wrap the four top corners of the electronic device 30, and the four top corners of the electronic device 30 can fit tightly into the arc-shaped depressions of the protrusions 114, so that the electronic device 30 is stably fixed in the receiving groove 111, thereby improving the alignment accuracy between the film assembly 20 and the electronic device 30.

[0079] In addition, the conventional film applicator places the electronic device 30 as a whole into the positioning groove, and the side wall of the electronic device 30 contacts the entire groove wall of the positioning groove. In this embodiment, the arc-shaped depression of the protrusion 114 has a smaller contact area with the electronic device 30, but the distribution of the protrusion 114 can also effectively fix the electronic device 30, reducing the risk of damage caused by friction between the contact surface of the electronic device 30 and the film applicator box 10.

[0080] Furthermore, if Figure 2 As shown, a reinforcing rib 115 connecting each protrusion 114 is provided at the bottom of the receiving groove 111 .

[0081] The reinforcing ribs 115 can enhance the supporting strength of the receiving groove 111 to prevent the film sticking box 10 from being damaged by external impact during transportation and use.

[0082] Furthermore, the film sticking box 10 further includes an adhesive member 116 , which is disposed at the bottom of the first groove 113 , and is used to fix the film sticking assembly 20 .

[0083] like Figure 6 As shown, in other embodiments, an adhesive member 116 may be further provided at the bottom of the first groove 113 , and the adhesive member 116 can be glued to fix the film assembly 20 , thereby further fixing the film assembly 20 .

[0084] The direction from the film outlet 117 to the end of the film sticking box 10 opposite to the film outlet 117 is defined as the length extension direction of the first groove 113. Figure 6 As shown, the adhesive member 116 may be in a strip shape and extend along the length extension direction of the first groove 113. In other embodiments, the adhesive member 116 may also be circular or in other shapes, and there may be a plurality of adhesive members 116 evenly distributed at the bottom of the first groove 113, or the adhesive members 116 may also be evenly spaced and distributed along the edge of the bottom of the first groove 113, or the adhesive members 116 may also be randomly distributed at the bottom of the first groove 113.

[0085] Furthermore, if Figure 1 As shown, the film sticking box 10 includes a box body 11 and a cover body 12 covering the box body 11, a receiving groove 111 is provided in the box body 11, a film outlet 117 is provided on the side of the box body 11, and the cover body 12 is movably connected to a side of the box body 11 where the film outlet 117 is not provided.

[0086] Compared with ordinary film applicators, the box body 11 of the film applicator 10 is covered with a cover 12. The electronic device 30 can be placed in the receiving slot 111, the cover 12 is closed, the tear strip 24 is pulled, and the cover 12 is directly pressed to apply pressure to the electronic device 30, and the film can be applied.

[0087] On the one hand, the cover body 12 and the box body 11 surround the receiving groove 111, blocking external dust and preventing impurities from entering between the protective film 22 and the electronic device 30 when the film is applied; on the other hand, traditional film applicators will be placed in a packaging box for protecting the film applicator or a packaging bag with cushioning material after production, while the present film applicator box 10 has a certain anti-collision ability, and the box body 11 and the cover body 12 can protect the internal receiving groove 111, which greatly saves the packaging material of the film applicator box 10, reduces costs, and is more environmentally friendly.

[0088] It should be understood that the cover 12 can be made of an elastic and deformable material, such as plastic, and even if the thickness of the electronic device 30 is different, pressure can be applied to the elastic cover 12 to the electronic device 30. An elastic body capable of slight deformation, such as foam, rubber, etc., can also be installed on the side of the cover 12 facing the box body 11. When the cover 12 is pressed, the elastic body will deform, and a film can be applied to electronic devices 30 of various thicknesses.

[0089] Furthermore, the box body 11 and the cover body 12 are integrally formed, and the receiving groove 111 is integrally formed.

[0090] The receiving groove 111, the box body 11 and the cover body 12 can be made of plastic or cardboard. The production cost of these two materials is low, and they can be recycled many times, which is more environmentally friendly. The receiving groove 111 can be integrally formed with the box body 11 and the cover body 12, or it can be separately formed with the box body 11 and the cover body 12 using different materials and then assembled together.

[0091] The materials of the box body 11 , the cover body 12 and the receiving groove 111 are merely examples, and the present invention does not limit the materials of the box body 11 , the cover body 12 and the receiving groove 111 .

[0092] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
