Description

Technical Field

[0001] This utility model relates to the field of electronic product film application equipment technology, and in particular to an embedded positioning dust-free book film applicator and kit. Background Technology

[0002] Electronic products such as tablets generally do not have screen protectors applied when they leave the factory, so users usually need to apply a screen protector to protect the screen after purchasing such products.

[0003] There are already screen protector applicators on the market for this type of product, but existing applicators are generally open-type, which makes it easy for dust to get in and affect the application. They are also prone to misalignment and are cumbersome and inconvenient for users.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an embedded positioning dust-free book film applicator and kit, which aims to reduce dust entry when applying film to electronic products such as tablet computers, and to provide accurate positioning and simple, fast and convenient film application.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In the first aspect, this utility model proposes an embedded positioning dust-free book film applicator, which includes a hinge that can be folded and closed or opened, and a film applicator seat disposed on the hinge. The film applicator seat includes a positioning groove located in the middle and a baffle wall surrounding the positioning groove. The baffle wall is provided with positioning protrusions for positioning on one or more sides of the positioning groove. When the hinge is closed, it covers the film applicator seat.

[0008] In some embodiments, the positioning groove is a rectangular groove, and positioning protrusions are respectively provided on the top side and the left and right side walls of the positioning groove.

[0009] In some embodiments, a membrane step is formed on the upper surface of the baffle, and the positioning protrusion is provided on the membrane step.

[0010] In some embodiments, the baffle is further provided with a limiting edge that extends above the membrane step on the outside of the membrane step.

[0011] In some embodiments, the baffle is provided with a pull-out notch on the bottom side of the positioning groove.

[0012] In some embodiments, the hinge includes an upper hinge, a lower hinge, and a connecting piece connecting the upper hinge and the lower hinge, and the film holder is disposed on the lower hinge.

[0013] In some embodiments, the inner surface of the upper hinge is provided with a pressing strip, which is located above the positioning groove when the hinge is closed, and the pressing strip is used to press the film assembly used when applying the film.

[0014] In some embodiments, the hinge is a paper card.

[0015] Secondly, this utility model also proposes an embedded positioning dust-free book film applicator kit, which includes the aforementioned embedded positioning dust-free book film applicator and a film assembly. The film assembly includes a positioning PET film, tempered glass, an adhesive layer, and a pull-out layer that are sequentially bonded together. The edge of the positioning PET film is provided with a positioning hole that engages with the positioning protrusion.

[0016] In some embodiments, the pull-out layer is a bent double-layer structure, including a protective sheet and a pull strip. The protective sheet is bonded to the adhesive layer, one end of the protective sheet is connected to one end of the pull strip, and the other end of the pull strip can be exposed from the bottom side of the positioning groove of the film holder.

[0017] It should be understood that, within the scope of this utility model, the above-mentioned technical features of this utility model and the technical features specifically described below (such as embodiments) can be combined with each other to form new or preferred technical solutions. Due to space limitations, they will not be described in detail here.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model adopts a book-style hinge design with a film applicator inside the hinge. When applying a film to a tablet computer, the tablet computer is placed in the positioning slot of the film applicator, the film assembly is placed on top, and then the hinge is closed to perform the film application. After the hinge is closed, dust is reduced from entering the interior. At the same time, combined with the pull-out film application method, dust is difficult to enter between the screen and the film assembly during the film application process, achieving dust-free film application.

[0020] 2. This utility model has a positioning groove and a positioning protrusion on the film application base. The positioning groove can position the product to be applied, such as a tablet computer, and the positioning protrusion can position the film assembly. In this way, the tablet computer and the film are in a positioning and aligned state during the film application process, so that the film application is accurate and will not be applied crookedly.

[0021] 3. The hinge design and the design of the positioning groove and positioning protrusion of this utility model make the film application process simple and convenient. Just put in the product to be filmed, put in the film assembly and snap it into the positioning protrusion, close the hinge, pull out the pull-out layer of the film assembly, and then place the positioning PET film of the film assembly to complete the film application.

[0022] 4. The screen protector can also be used as a packaging box. For example, when the product such as a tablet computer purchased by the user is shipped, it can be placed directly into the positioning slot of the screen protector, and then the screen protector and the tablet computer can be shipped as a whole, which can save packaging costs.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a quick-release connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0038] This utility model discloses an embedded positioning dust-free book-type film applicator 100, including a foldable hinge 1 and a film applicator base 2 disposed on the hinge 1. Since the hinge 1 can open and close like a book, the film applicator 100 of this utility model is a book-type film applicator. The film applicator base 2 is used to hold products with applied films, such as tablet computers and mobile phones. The film applicator base 2 and the hinge 1 can be fixed by adhesive, snap-fit, or the film applicator base 2 and the hinge 1 can be an integral structure.

[0039] The film-applying base 2 of this utility model includes a positioning groove 21 located in the middle and a baffle wall 22 surrounding the positioning groove 21. The baffle wall 22 is provided with positioning protrusions 23 for positioning on one or more sides of the positioning groove 21. When the hinge 1 is closed, it covers the film-applying base 2.

[0040] The positioning groove 21 serves two purposes: first, to place the electronic product to be coated with the film; and second, to position and limit the electronic product in conjunction with the surrounding baffle 22, preventing it from moving during the film coating process. The positioning groove 21 can be a through groove or a closed groove.

[0041] The positioning protrusion 23 is used to engage and position the membrane assembly during the film application process, ensuring alignment between the membrane assembly and the product to be filmed and preventing movement of the membrane assembly. The positioning protrusion 23 can be located on one side of the positioning groove 21, such as the top, left, right, or bottom. Alternatively, the positioning protrusion 23 can be located on multiple sides of the positioning groove 21, such as simultaneously on the top, left, right, and bottom, which enhances its positioning effect on the membrane assembly.

[0042] When applying the film, first open the hinge 1 of this utility model, then place the electronic product to be filmed into the positioning groove 21 of the film application base 2, then place the film assembly on the upper surface of the screen of the electronic product, and engage the edge of the film assembly with the positioning protrusion 23. Then close the hinge 1, pull out the bottom pull-out layer of the film assembly from the hinge 1, so that the tempered glass inside the film assembly is attached to the screen of the electronic product. Then press the hinge tightly to fully bond the tempered glass to the screen of the electronic product. Then open the hinge 1 and peel off the positioning PET film on the top of the film assembly to complete the film application.

[0043] Thus, during the application process, the embedded positioning dust-free book screen protector 100 of this invention creates a relatively enclosed space within the positioning groove 21 of the screen protector holder 2 because the hinge 1 is closed. This significantly reduces the amount of dust entering the positioning groove 21. Furthermore, the screen protector 100 employs a pull-out application method after the hinge is closed, effectively preventing dust from adhering to the tempered glass screen protector within the screen protector assembly. Because positioning protrusions 23 are provided on one or more sides of the positioning groove 21 of the screen protector holder 2, the screen protector is precisely aligned with the screen during application, preventing misalignment. The entire application process is simple and quick.

[0044] Example 1, as Figures 1 to 3 As shown, in this embodiment, the hinge 1 and the film holder 2 are fixed by adhesive bonding. The positioning groove 21 in this embodiment is a rectangular groove, which can adapt to rectangular shapes such as tablet computers and mobile phones. In other embodiments, the positioning groove 21 can also be a circular groove or other shapes. The positioning groove 21 in this embodiment is a through groove. Positioning protrusions 23 are respectively provided on the top side 211 and the left and right side baffles 22 of the positioning groove 21 in this embodiment. For example... Figure 3 As shown, the rectangular positioning groove 21 of the film-applying base 2 is divided into a top side 211, a left side 212, a right side 213, and a bottom side 214. In this embodiment, positioning protrusions 23 are provided on the baffles 22 of the top side 211, left side 212, and right side 213 of the positioning groove 21. Each side baffle 22 can have one or more positioning protrusions 23. For example, in this embodiment, two positioning protrusions 23 are provided on the baffle 22 of the top side 211, one positioning protrusion 23 is provided on the baffle 22 of the left side 212, and one positioning protrusion 23 is provided on the baffle 22 of the right side 213. In this embodiment, a total of four positioning protrusions 23 are provided to engage and position the membrane assembly, thus making the positioning of the membrane assembly more accurate. The positioning protrusions 23 can be cylindrical, block-shaped, or other shapes.

[0045] Preferably, in this embodiment, a membrane step 24 is formed on the upper surface of the baffle 22, and the positioning protrusion 23 is provided on the membrane step 24. When applying the film, the edge of the film assembly presses against the membrane step 24, and the membrane step 24 supports the edge of the film assembly, so that after the film assembly is placed on the screen of the electronic product to be covered, the edge and center of the film assembly are at the same height, preventing the film assembly from bending and affecting the application. At the same time, the positioning protrusion 23 on the membrane step 24 can lock and limit the film assembly, preventing the film assembly from moving during the application process.

[0046] Preferably, such as Figure 3 As shown, the baffle 22 is further provided with a limiting edge 25 protruding above the membrane step 24 on the outer side of the membrane step 24. The limiting edge 25 blocks the outer perimeter of the membrane step 24, which serves two purposes: firstly, it frames the outer edge of the membrane assembly during the film application process, allowing for quick positioning of the membrane assembly; secondly, it prevents the membrane assembly from moving out of the membrane step 24 during placement. The limiting edge 25 provides initial positioning of the membrane assembly, while the positioning protrusion 23 precisely positions the membrane assembly after this initial positioning.

[0047] Furthermore, such as Figure 3 As shown, the baffle 22 has a pull-out notch 26 on the bottom side 214 of the positioning groove 21. The pull-out notch 26 allows the pull-out layer 204 of the film assembly to be easily pulled out during the film application process, so that the bottom surface of the tempered glass film can be smoothly adhered to the screen of the electronic product to be filmed.

[0048] In this embodiment, as Figure 3 As shown, the baffle 22 is further provided with a bottom wall step 27 at the bottom of the positioning groove 21. The bottom wall step 27 can support the bottom surface of the electronic product to be coated, so that the electronic product to be coated is in a flat state, which is conducive to coating.

[0049] like Figure 2 As shown, the hinge 1 in this embodiment includes an upper hinge 11, a lower hinge 12, and a connecting piece 13 connecting the upper hinge 11 and the lower hinge 12. The film holder 2 is disposed on the lower hinge 12. When the hinge 1 is closed, the upper hinge 11 is located above the lower hinge 12. Preferably, the hinge 1 in this embodiment is a paper card, that is, the hinge 1 in this embodiment is made of paper material and divided into three foldable and openable parts. In other embodiments, the hinge 1 can also be made of materials such as plastic.

[0050] Furthermore, a pressing strip 3 is provided on the inner surface of the upper hinge 11. When the hinge 1 is closed, the pressing strip 3 is located above the positioning groove 21. The pressing strip 3 is used to press the film assembly used during film application. After the pressing strip 3 presses the film assembly 200, it prevents the tempered glass from moving and affecting the bonding accuracy when the pull-out layer 204 of the film assembly is pulled out. The pressing strip 3 is preferably made of a flexible material, such as sponge or rubber.

[0051] Example 2, as Figure 4 As shown, this embodiment also discloses an embedded positioning dust-free book film applicator 100. The difference between it and the first embodiment is that the positioning protrusions 23 in the second embodiment are only set on the baffle 22 of the top side 211 of the positioning groove 21. At the same time, the number of positioning protrusions 23 set on the baffle 22 of the top side 211 in the second embodiment is more than that in the first embodiment. There are four positioning protrusions 23 set on the baffle 22 of the top side 211 in the second embodiment. Four positioning protrusions 23 on one side can also accurately position the film assembly 200.

[0052] Example 3, as Figures 5 to 8 As shown, this utility model discloses an embedded positioning dust-free book film applicator kit 300, including the aforementioned embedded positioning dust-free book film applicator 100, and also includes a film assembly 200. The film assembly 200 includes a positioning PET film 201, tempered glass 202, an adhesive layer 203, and a pull-out layer 204 sequentially bonded together. The edge of the positioning PET film 201 is provided with positioning holes 2011 that engage with the positioning protrusions 23. In this embodiment, as... Figure 7 As shown, an overlapping block 2012 is provided on the edge of the positioning PET film 201 extending outward. The overlapping block 2012 can overlap on the film step 24 of the film attaching seat 2. The positioning hole 2011 is provided on the overlapping block 2012.

[0053] In this embodiment, the positioning PET film 201, tempered glass 202, adhesive layer 203, and pull-out layer 204 are integrally configured as a whole. The positioning PET film 201 is used for positioning, the adhesive layer 203 is used to adhere the tempered glass 202 to the screen of the electronic product to be filmed, and the pull-out layer 204 is used to pull away from the adhesive layer 203 during film application. In this embodiment, the overlapping blocks 2012 on the outer edge of the positioning PET film 201 all extend beyond the outer edge dimensions of the tempered glass 202, adhesive layer 203, and pull-out layer 204. This ensures that when the film assembly 200 is placed in the film application holder 2, the tempered glass 202, adhesive layer 203, and pull-out layer 204 can all be accommodated within the positioning groove 21, and the overlapping blocks 2012 of the positioning PET film 201 overlap the film step 24 for subsequent locking and positioning.

[0054] like Figure 6 As shown, the pull-out layer 204 in this embodiment is a bent double-layer structure, including a protective sheet 2041 and a pull strip 2042. The protective sheet 2041 is bonded to the adhesive layer 203. The protective sheet 2041 is used to protect the tempered glass 202 when the film assembly 200 is not in use. The protective sheet 2041 and the pull strip 2042 are a detachable, non-adhesive double-layer structure. Specifically, one end of the protective sheet 2041 is connected to one end of the pull strip 2042, and the other end of the pull strip 2042 can protrude from the bottom side 214 of the positioning groove 21 of the film holder 2.

[0055] When using the film applicator kit 300 of this embodiment, such as Figure 5 As shown, first open hinge 1, then place tablet computer 400 into positioning groove 21 of screen protector holder 2, then place screen protector assembly 200, and engage positioning hole 2011 on screen protector assembly 200 with positioning protrusion 23 on screen protector holder 2, as shown. Figure 8 As shown, at this time, the lower end of the pull strip 2042 of the pull layer 204 of the film assembly 200 is exposed from the pull notch 26 at the bottom of the film holder 2. Then, the hinge 1 is closed and the upper hinge 11 is pressed down. Then, the lower end of the pull strip 2042 is pulled out from the pull notch 26 to separate the protective sheet 2041 from the adhesive layer 203, so that the lower surface of the adhesive layer 203 is bonded to the upper surface of the tablet computer screen 400 to fix the tempered glass 202 on the screen. Then, the hinge 1 is opened and the positioning PET film 201 of the film assembly 200 is peeled off to complete the film application.

[0056] The above description is merely an example to clearly illustrate the present utility model and is not intended to limit the patent scope of the present utility model. It is impossible to exhaustively list all the embodiments here. All equivalent structural transformations made using the content of the technical solution of the present utility model under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
