Technical Field

[0001] The utility model relates to the technical field of electronic device accessories, in particular to an automatic exhaust dust-free film application box. Background Art

[0002] With the popularization of intelligent electronic devices, the protection of electronic device screens has become a common concern for users. There are many film applicators on the market that can realize the function of quickly applying films to electronic devices.

[0003] However, the existing film applicators also have some deficiencies: when the existing film applicators apply films to electronic devices, the first contact point between the protective film and the electronic device screen is relatively random. Therefore, after the protective film is completely attached to the screen, scattered bubbles will remain, and manual pushing and squeezing are required for exhaust, which is rather inconvenient. Summary of the Invention

[0004] The utility model provides an automatic exhaust dust-free film application box to solve the above-mentioned existing technical problems.

[0005] The technical solution of the utility model is realized as follows:

[0006] An automatic exhaust dust-free film application box includes a positioning box, a film application assembly is installed on the positioning box, and an elastic top block is further provided on one surface of the positioning box in contact with the film application assembly.

[0007] Furthermore, a slot for accommodating the elastic top block is provided on the positioning box, and the elastic top block is a component with a protruding part connected to one end of the positioning box.

[0008] Furthermore, a first positioning member and a second positioning member for installing the film application assembly are further provided on the positioning box.

[0009] Furthermore, a positioning post is further provided on the positioning box near the first positioning member.

[0010] Furthermore, both the first positioning member and the second positioning member are buckle-shaped components provided on the positioning box, and the top surfaces of the first positioning member and the second positioning member are both treated with inclined surfaces.

[0011] Furthermore, a positioning frame for positioning the electronic device is integrally provided on the positioning box; a central opening is also formed on the positioning box body.

[0012] Furthermore, a plurality of cushion strips are provided on the inner wall of the positioning frame, and a drawing opening is reserved at one end of the positioning frame.

[0013] Further, the film laminating assembly includes a release film, a positioning film, a protective film, and a pull film. The positioning film is provided with first positioning combination holes corresponding to the first positioning member and the positioning posts. The protective film is adhered to one side of the positioning film, and the release film is adhered to the other side of the protective film. The release film is provided with second positioning combination holes corresponding to the second positioning member. The pull film is installed on the release film.

[0014] Further, one end of the release film away from the second positioning combination hole is provided with a folding portion, and a double-sided adhesive is adhered inside the folding portion.

[0015] Further, one end of the pull film is connected to the folding portion provided on the release film and adhered to the double-sided adhesive.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, by providing an elastic top block with a convex portion on the positioning box, when the film laminating assembly is installed on the positioning box and then covered on the screen of the electronic device, the elastic top block can push out the film laminating assembly, and the portion of the film laminating assembly pushed out by the elastic top block becomes the contact point with the screen of the electronic device. When the pull film is pulled out, the protective film can be made to fit the screen of the electronic device first from the position where the elastic top block is located. The protective film can gradually fit the screen of the electronic device starting from the first contact and fitting point with the screen of the electronic device. Since this fitting method makes the first contact and fitting point between the protective film and the screen of the electronic device determined, and starting from the contact and fitting point, the protective film gradually fits the screen of the electronic device, and the direction of gradual fitting is determined, it can play a role in gradually exhausting air during the fitting process and will not generate scattered bubbles. This solves the problem that in the prior art, when using a film laminating device to laminate an electronic device, the first contact point between the protective film and the screen of the electronic device is relatively random. Therefore, after the protective film is completely fitted to the screen, scattered bubbles will remain, and manual pushing and squeezing are required for exhausting air, which is rather inconvenient.

[0024] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figures 1-5 shown, an automatic exhaust dust-free film pasting box includes a positioning box 1, a film pasting assembly 2 is installed on the positioning box 1, and an elastic top block 3 is further provided on one surface of the positioning box 1 in contact with the film pasting assembly 2.

[0026] Further, a groove 4 for accommodating the elastic top block 3 is provided on the positioning box 1, and the elastic top block 3 is a component with a convex part 31 connected to one end of the positioning box 1.

[0027] Since the elastic top block 3 is only connected to the positioning box 1 at one end and is received in the groove 4, except for the end connected to the positioning box 1, the other outer walls are not connected to the positioning box 1. Therefore, the elastic top block 3 has a certain range of movement on the positioning box 1.

[0028] In this embodiment, by using the elastic top block 3 provided on the positioning box 1, during the process of applying a film to the electronic device, the part of the film applying assembly 2 ejected by the elastic top block 3 becomes the contact point with the screen of the electronic device. At the same time, due to the existence of the elastic top block 3, the part of the film applying assembly 2 corresponding to the screen of the electronic device is inclined at a certain angle, which is beneficial to the subsequent falling of the protective film 23 and gradually fitting with the screen of the electronic device. When pulling out the pull film 24, the protective film 23 can first fit with the screen of the electronic device from the position where the elastic top block 3 is located, and then, by using the self-gravity of the protective film 23, it gradually fits with the screen of the electronic device from the contact point to other directions. By using this method to determine the first contact point between the protective film 23 and the screen of the electronic device, this method solves the problem in the prior art that due to the relatively random first contact point between the protective film 23 and the screen of the electronic device during film application, scattered bubbles will remain after the film application is completed.

[0029] Further, a first positioning member 5 and a second positioning member 6 for installing the film applying assembly 2 are also provided on the positioning box 1.

[0030] Further, a positioning post 7 is also provided on the positioning box 1 near the first positioning member 5.

[0031] Further, both the first positioning member 5 and the second positioning member 6 are buckle-shaped components provided on the positioning box 1, and the top surfaces of the first positioning member 5 and the second positioning member 6 are both processed with inclined surfaces.

[0032] Further, a positioning frame 8 for positioning the electronic device is integrally provided on the positioning box 1; a middle opening 9 is also opened on the body of the positioning box 1.

[0033] Further, a plurality of cushion strips 10 are provided on the inner wall of the positioning frame 8, and a pull opening 11 is reserved at one end of the positioning frame 8.

[0034] Further, the film applying assembly 2 includes a release film 21, a positioning film 22, a protective film 23 and a pull film 24. A first positioning combination hole 221 corresponding to the first positioning member 5 and the positioning post 7 is provided on the positioning film 22. The protective film 23 is pasted on one side of the positioning film 22, the release film 21 is pasted on the other side of the protective film 23, a second positioning combination hole 211 corresponding to the second positioning member 6 is provided on the release film 21, and the pull film 24 is installed on the release film 21. When pulling the pull film 24 connected to the release film 21, the pull film 24 and the release film 21 can be removed together when pulled to the end position. In this process, the second positioning member 6 with an inclined surface treatment will not hinder the detachment of the second positioning combination hole 211, which can make the detachment of the second positioning combination hole 211 from the second positioning member 6 smoother; when the positioning film 22 needs to be disassembled after the film application is completed, the first positioning member 5 with an inclined surface treatment can make the removal of the positioning film 22 smoother.

[0035] Further, one end of the release film 21 away from the second positioning combination hole 211 is provided with a folding portion 212, and a double-sided adhesive 213 is pasted inside the folding portion 212.

[0036] Further, one end of the draw film 24 is connected to the folding portion 212 provided on the release film 21 and adhered to the double-sided adhesive 213. When the draw film 24 is drawn out, the release film 21 can be drawn out together.

[0037] The working process and principle of the present utility model are as follows:

[0038] Before the present utility model pastes a film on the screen of an electronic device, the film pasting assembly 2 is installed and fixed on the positioning box 1 according to the positions of the first positioning member 5 and the second positioning member 6 corresponding to the first positioning combination hole 221 and the second positioning combination hole 211 through the positioning film 22 provided with the first positioning combination hole 221 and the release film 21 provided with the second positioning combination hole 211. At this time, one side part of the film pasting assembly 2 is pushed out by the elastic top block 3 provided on the positioning box 1, and the film pasting assembly 2 is at a certain inclination angle; the positioning box 1 installed with the film pasting assembly 2 is covered on the screen of the electronic device, so that the draw film 24 is attached to the screen of the electronic device. At this time, the part of the film pasting assembly 2 close to the elastic top block 3 is in the closest contact with the screen of the electronic device, which is the first contact point with the screen of the electronic device and serves as the starting point for the attachment of the protective film 23. By pulling out the draw film 24 and simultaneously pulling the release film 21 together, the protective film 23 falls and starts to attach from the first contact point. Using the self-gravity of the protective film 23, the protective film 23 gradually attaches to the screen of the electronic device in other directions from the first contact point. In this process, since the attachment process of the protective film 23 to the screen of the electronic device is gradually covered in a linear direction, it avoids the scattered bubbles caused by random attachment points.

[0039] The specific embodiments of the utility model have been described in detail above, but they are only examples. The present utility model is not limited to the specific embodiments described above. Those skilled in the art of this industry should understand that the above embodiments and the descriptions in the specification only illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
