[0034] In the description of this utility model, "a plurality" means more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 As shown, a film-applying device according to an embodiment of the present invention includes a base box 100 and a diaphragm assembly 200. The base box 100 is provided with a positioning groove 110, which is used to accommodate an electronic product 300 (such as a mobile phone, a tablet computer, etc.). The notch of the positioning groove 110 faces upward. After the electronic product 300 is loaded into the positioning groove 110, it can be constrained by the positioning groove 110 so that the screen 310 of the electronic product 300 faces upward, thereby achieving positioning of the screen 310. The diaphragm assembly 200 is provided at the notch of the positioning groove 110. The diaphragm assembly 200 includes a positioning film 210, a protective film 220, a release film 230 and a pull tab 240 connected in sequence along the direction close to the bottom wall of the positioning groove 110. The positioning film 210 is connected to the non-adhesive surface of the protective film 220, and the release film 230 is connected to the adhesive surface of the protective film 220. During transportation of the film-applying device according to this embodiment, the base box 100 and the diaphragm assembly 200 are assembled together for transportation.

[0037] Continue to refer to Figure 2 and Figure 3As shown, a connection portion 211 is provided on one side of the positioning film 210. The connection portion 211 is fixedly connected to one side of the bottom box 100. The connection portion 211 can be fixedly connected to the bottom box 100 by means of snapping, bonding, etc. The connection portion 211 is flexible, and the diaphragm assembly 200 is configured to be able to rotate relative to the bottom box 100 under the elastic deformation of the connection portion 211 to open the notch of the positioning groove 110 or cover the notch of the positioning groove 110. When the diaphragm assembly 200 opens the notch, the user can conveniently place the electronic product 300 into the positioning groove 110; when the diaphragm assembly 200 covers the notch, the protective film 220 can be accurately aligned with the screen 310 of the electronic product 300, thereby improving the convenience of the film application operation and enhancing the user experience.

[0038] The release film 230 has a first protrusion 231 protruding from the protective film 220 on the side near the connection portion 211, and the pull tab 240 has a second protrusion 241 protruding from the protective film 220 on the side near the connection portion 211. The first and second protrusions 231, 241 are bonded to each other on opposite sides by adhesive. The connection between the pull tab 240 and the release film 230 is relatively flat and lacks a folding structure. Therefore, the pull tab 240 and the release film 230 do not bulge at the contact point, which could cause the release film 230 to peel off the protective film 220. The connection structure between the pull tab 240 and the release film 230 of this embodiment of the utility model can prevent the release film 230 from curling up, allowing the release film 230 to be securely attached to the adhesive surface of the protective film 220. This effectively prevents the adhesive surface from being exposed during transportation and causing oxidation failure, reduces the generation of bubbles after film application, and ensures the quality of the film application.

[0039] During the film sticking process of the film sticking device of this embodiment, the user pulls the pull tab 240 with his fingers, and the pull tab 240 drives the release film 230 to peel off the protective film 220, so that the protective film 220 is suspended above the screen 310 of the electronic product 300. At this time, the user presses the protective film 220 with his fingers to make the protective film 220 adhere to the screen 310; after the protective film 220 and the positioning film 210 are separated, the electronic product 300 can be taken out of the bottom box 100.

[0040] Reference Figure 3 As shown, a pull tab 240 according to one embodiment of the present invention includes a dust removal tab 242 and a connecting tab 243. The dust removal tab 242 removes dust through electrostatic adsorption. Since the dust removal tab 242 and the connecting tab 243 are made of different materials, for ease of assembly, the connecting tab 243 is connected to the side of the dust removal tab 242 facing away from the release film 230, for example, by gluing. Part of the connecting tab 243 is connected to the dust removal tab 242, and the portion of the connecting tab 243 that protrudes from the dust removal tab 242 forms a second protrusion 241.

[0041] As an alternative embodiment, the pull tab 240 is an integrally formed part, which is more convenient to process and to assemble.

[0042] In a diaphragm assembly 200 according to an embodiment of the present invention, the first protrusion 231 and the second protrusion 241 are of the same size and overlap with each other, which further reduces the influence of the pull-tab 240 on the release film 230 and ensures the reliability of the pull-tab 240 driving the release film 230 to peel off the protective film 220 during the film application process.

[0043] Reference Figure 1 、 Figure 4 and Figure 6 As shown, it can be understood that the top wall 130 of the bottom box 100 is provided with two positioning bosses 120, which are arranged on both sides of the positioning groove 110. The positioning film 210 is provided with positioning holes 212 on both sides that cooperate with the positioning bosses 120. The cooperation structure of the two positioning bosses 120 and the two positioning holes 212 can perform secondary positioning of the positioning film 210, ensuring the positioning accuracy between the protective film 220 and the screen 310.

[0044] Reference Figure 6 As shown, it can be understood that the two positioning bosses 120 are of the same size and are symmetrically arranged along the center line L of the positioning groove 110, and therefore the two positioning holes 212 are of the same size and are symmetrically arranged along the center line L of the positioning groove 110. Using positioning bosses 120 of the same size can reduce the processing accuracy of the bottom box 100 and reduce the difficulty of matching with the positioning holes 212. Because the diaphragm assembly 200 and the bottom box 100 are already firmly connected at the factory, the user does not need to assemble the diaphragm assembly 200 during use, so there is no need to set up a fool-proof structure. In addition, the solution of using positioning bosses 120 and positioning holes 212 of the same size in this embodiment is more convenient for users to operate.

[0045] Reference Figure 5 As shown, it can be understood that the width of at least part of the pull tab 240 gradually decreases in the direction away from the connecting portion 211. The shape of the pull tab 240 has an identification function to guide the user's operation, and can save materials and reduce production costs.

[0046] Reference Figure 1 As shown, it can be understood that the side of the pull tab 240 away from the connecting portion 211 protrudes from the protective film 220 and abuts against the top wall 130 of the bottom box 100, making it easy for the user to operate the pull tab 240 and drive the release film 230 to peel off the protective film 220.

[0047] Reference Figure 7 and Figure 8As shown, it can be understood that the connecting portion 211 is fixedly connected to the top wall 130 of the bottom box 100, and the positioning groove 110 is configured so that when the electronic product 300 is installed in the positioning groove 110, the screen 310 of the electronic product 300 is lower than the plane where the top wall 130 is located, that is, there is a gap between the screen 310 and the plane where the top wall 130 is located. Figure 8 The gap h in the screen 310 is defined as follows. It is understood that if large particles of dust or sand remain on the surface of the screen 310 of the electronic product 300, the pull tab 240 may damage the screen 310 when it is slid across the screen 310. In this embodiment, the provision of the gap h prevents the dust removal sheet 242 from exerting significant force on the screen 310 when slid across the screen 310. Instead, the dust removal sheet 242 merely contacts the screen 310 and removes dust through electrostatic adsorption, effectively reducing the risk of damage to the screen 310.

[0048] Reference Figure 1 、 Figure 7 and Figure 8 As shown, it is understood that the film applying device further includes a fixing piece 400, which is used to adhere the connecting portion 211 to the top wall 130 of the bottom box 100. The fixing piece 400 can achieve a stable connection between the connecting portion 211 and the bottom box 100, improve the connection reliability of the diaphragm assembly 200 and the bottom box 100, and prevent the diaphragm assembly 200 from falling out of the bottom box 100 during the rotation relative to the bottom box 100.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
