Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone film pasting tools, in particular to a dust-free film pasting component adapted to a variety of tempered films. Background Art

[0002] As we all know, tempered glass mobile phone film is a mobile phone protective film, which is a high-end new product with the most enhanced protection for the screen. The thickness of this protective layer is only 0.6 mm, which can completely cover the original screen surface to prevent damage and scratches from external forces, and increase the impact absorption, which is many times higher than the standard of PET film, and will not affect the video effect of the screen. Therefore, it is deeply loved by users.

[0003] However, for tempered glass films, although the difficulty of applying the film is more convenient than that of conventional soft films, relevant film applying skills are still required, especially the angle placement of the tempered film, which is completely dependent on the naked eye and experience. Once the angle is wrong, it will directly affect the effect, and even need to be torn off again, and then re-centered. The operation process is extremely easy to damage the tempered film. Therefore, in order to facilitate consumers to complete the film application quickly and accurately, some film application artifacts will be extended, such as CN202221159350.9 A tempered film film application auxiliary device and tempered film assembly. This prior patent mainly relies on setting a frame for limiting the position of the mobile phone, and then a fitting part (magnetic suction sheet) needs to be set up to fix the tempered film on the frame. Although it can complete the tempered film of the mobile phone well, it is found in production that the establishment of the fitting part will increase the cost and is not conducive to market promotion. In addition, limiting columns for limiting the position of the tempered film are arranged inside the frame, so the size of the tempered film must correspond to the structure of the frame, that is, the size of the tempered film is fixed, and for the same mobile phone, the size of the tempered film is different, some are fully covered, and some have exposed parts (that is, after the tempered film is attached, there is a spare part around the tempered film and the mobile phone screen, and this is mainly done to meet the assembly requirements of the full-coverage mobile phone case), so when dealing with changes in the size of different tempered films, it is necessary to design a variety of frame structures, which will result in the need to open a variety of molds, thereby causing the production cost to increase again.

[0024] like Figures 1 to 6As shown, the present embodiment provides a dust-free film assembly adapted to a variety of tempered films, including:

[0025] A tempered film assembly 1, the tempered film assembly 1 comprising a tempered film 11, a tear sheet 12, a holding sheet 13 and a release film 14 for protecting the adhesive surface of the tempered film, one end of the tear sheet 12 is connected to one end of the release film 14 through a bending portion 15, so that the tear sheet 12 is stacked on the surface of the release film 14, the other end of the tear sheet 12 is provided with a gripping end 121 that exceeds the edge of the release film 14, the lower end surface of the release film 14 is in contact with the adhesive surface of the tempered film 11, the other end surface of the tempered film 11 relative to the adhesive surface is adhered to the holding sheet 13, both ends of the holding sheet 13 are provided with extensions 131, the extensions 131 are provided with through holes 132, and the number of through holes 132 on at least one of the extensions 131 is at least two;

[0026] The film applicator 2 comprises a frame 21 for placing a mobile phone, the inner side wall of the frame 21 is evenly provided with limiting strips 22, the space enclosed by the limiting strips 22 is consistent with the size of the mobile phone placed therein, the frame 21 is provided with an avoidance opening 23 at the extension portion 131, the frame 21 is provided with a limiting column 24 for plugging with the insertion hole 132 at the avoidance opening 131, and an insertion opening 25 is provided at one side end of the frame 21;

[0027] Among them, the tempered film assembly 1 is inserted through the insertion port 25, so that the containing sheet 13 is placed at the bottom layer of the inner frame of the frame body 21, the pulling sheet 12 is located at the outermost layer, and the gripping end of the pulling sheet 12 is placed outside the insertion port 24, and the limiting columns 24 are respectively inserted into the corresponding insertion holes 132.

[0028] The design of this embodiment is mainly to directly add a holding piece 13 that can form a position limit with the frame 21, and rely on the bonding of the holding piece 13 to maintain the position limit of the tempered film 11. On the one hand, there is no need to install a limiting structure of the tempered film 11 in the frame 21, which simplifies the structure of the frame 21. On the other hand, this structure can be relied on to adapt to tempered films 11 of different sizes, thereby eliminating the need to open a variety of injection molds, effectively reducing costs.

[0029] When applying a film to a specific mobile phone, the operation is as follows:

[0030] The first step is to confirm that the tempered film assembly 1 and the film applicator 2 have been assembled (generally, when they are sold, they are assembled by default);

[0031] The second step is to clean the screen of the mobile phone, and then put the screen of the mobile phone facing down and buckle it in the inner frame of the frame body 21, and place the mobile phone in the center by relying on the limiting spacer 22 (generally, according to different mobile phone models, during injection molding production, only the protruding height of the limiting spacer 22 can be adjusted to meet the placement of different mobile phones);

[0032] In the third step, after the mobile phone is placed, the user only needs to hold the gripping end of the pull sheet 12 and then pull it outwards. In terms of design, the adhesive force between the holding sheet 13 and the tempered film 11 is greater than the adhesive force between the tempered film 11 and the release film 14. Therefore, as the mobile phone is continuously pulled outwards, the pull sheet 12 will gradually separate the release film 14 from the tempered film 11 by relying on the connection of the bent portion 15, so that the adhesive surface of the tempered film 11 is presented directly opposite to the mobile phone screen.

[0033] In the fourth step, external force is applied to the mobile phone to make the mobile phone screen and the adhesive surface of the tempered film 11 form a fit. In order to improve the bonding precision between the tempered film 11 and the mobile phone screen, a "T"-shaped hollow portion 26 is provided at the bottom of the inner frame of the frame body 21. Therefore, after the release film 14 is detached, the whole body can be reversed, and then the holding sheet 13 can be scraped and pressed through the hollow portion 26, and force is applied to the tempered film 11, so that the tempered film 11 is closely attached to the mobile phone screen;

[0034] In the fifth step, after the tempered film 11 is well attached to the mobile phone screen, the adhesive force between the adhesive surface of the tempered film 11 and the mobile phone screen will be very strong, and the force will be greater than the adhesive force between the containing sheet 13 and the tempered film 11. Therefore, you only need to remove the mobile phone from the frame 21, and the containing sheet 13 will automatically detach, so that the mobile phone film can be attached.

[0035] Furthermore, in order to prevent the containing sheet 13 from detaching, that is, the limiting column 24 from detaching from the insertion hole 132, the limiting column 24 of this embodiment is provided with a break 241 in the vertical direction, and the limiting column 24 is separated into at least two single columns 242 through the break 241, and at least one of the single columns 242 is provided with a hook portion 243 at the top end. In this way, the top end of the single column 242 is first deformed by relying on the break 241 to change the top end diameter, and then the insertion hole 132 is conveniently inserted. After the insertion is completed, the containing sheet 13 can be limited to detach by relying on the rebound of the single column 242 combined with the hook portion 243 at the top end, that is, the tempered film assembly 1 is detached from the film applicator 2.

[0036] Furthermore, when the pulling piece 12 is pulled, the surface of the pulling piece 12 will contact the upper end surface of the insertion port 25. In order to reduce the friction resistance between the pulling piece 12 and the insertion port 25 and make the operation smoother, the frame 21 of this embodiment is evenly provided with protrusions 251 on the upper end surface of the insertion port 25. The top end surface of the protrusion 251 is an arc surface. In this way, the arc surface of the protrusion 251 is used as the contact point to reduce the contact area, and the contact is made with a smooth surface, which can effectively reduce the friction resistance.

[0037] Furthermore, in order to prevent the frame 21 from slipping on the desktop during operation, anti-slip grooves 27 are provided on the bottom of the frame 21 in this embodiment.

[0038] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
