Description

Technical Field

[0001] This invention relates to the field of screen protection devices for electronic products, and more particularly to a screen protector applicator and a mobile phone screen protector assembly. Background Technology

[0002] To prevent scratches on the screens of digital electronic devices such as mobile phones and tablets during use, a screen protector is usually applied to the screen, which can largely protect the screen from scratches or damage. To facilitate production transfer, the screen protector typically has a release film and a positioning film at the top and bottom of the film, respectively. Therefore, the release film and positioning film need to be removed during the film lamination process.

[0003] Current screen protector application methods are generally done manually. This manual operation requires skilled personnel to apply the screen protector correctly in one go without creating air bubbles. If the personnel are not skilled, it is easy to misplace the screen protector and have to peel it off and reapply it. However, repeated peeling and reapplying will cause dust to stick to the adhesive side of the screen protector, creating air bubbles during the application process, thus rendering the entire screen protector unusable.

[0004] Therefore, how to develop a film applicator to overcome the above shortcomings has become a research topic for those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a screen protector and a mobile phone screen protector assembly to address the shortcomings of existing technologies.

[0007] As a further aspect of the present invention: the pad has a strip-shaped structure, the length of the pad is 50mm~140mm, the width is 5mm~40mm, and the height is 0.5mm~4mm.

[0008] As a further aspect of the present invention, it also includes several sets of positioning elements, each set of positioning elements having 4 positioning elements, the base being provided with a rectangular groove, the 4 positioning elements being detachably connected to the 4 corners of the rectangular groove respectively, and the 4 positioning elements forming the screen receiving groove.

[0009] As a further aspect of the present invention: any one of the four positioning elements is a right-angled trapezoidal structure, and the oblique waist of the right-angled trapezoidal structure is recessed with an R-corner portion. The bottom surface of any one of the positioning elements is also provided with a positioning hole. Each of the four corners of the rectangular groove is provided with a stop positioning post. The stop positioning post is inserted into the positioning hole so that the four positioning elements are respectively fixed to the four corners of the rectangular groove.

[0010] As a further embodiment of the present invention: the four positioning components are respectively the upper left positioning component, the lower left positioning component, the upper right positioning component, and the lower right positioning component, and the four corners of the rectangular groove are respectively the upper left corner, the lower left corner, the upper right corner, and the lower right corner. The upper left positioning component is fixedly placed at the upper left corner, the lower left positioning component is fixedly placed at the lower left corner, the upper right positioning component is fixedly placed at the upper right corner, and the lower right positioning component is fixedly placed at the lower right corner. The gap between the upper left positioning member and the lower left positioning member forms the left side groove, and the gap between the upper right positioning member and the lower right positioning member forms the right side groove.

[0011] As a further aspect of the present invention, it also includes a plurality of positioning frames, the base being provided with a rectangular groove, any one of the positioning frames being embedded in the rectangular groove, and the screen receiving groove being provided in the positioning frame.

[0012] As a further aspect of the present invention, the screen receiving slot is provided with a press-to-remove hole.

[0013] As a further aspect of the present invention: a front positioning post is provided at the front opening.

[0014] As a further embodiment of the present invention, it also includes a support rod and a pin. One end of the support rod is provided with a support rod hole. The side of the base is provided with a first support rod connection port. The back of the screen receiving groove has a protruding second support rod connection port. The end of the second support rod connection port near the first support rod connection port is provided with a support rod limiting part. The end of the support rod near the support rod hole is located between the first support rod connection port and the second support rod connection port. The pin is sequentially inserted through the first support rod connection port, the support rod hole, and the second support rod connection port.

[0015] The present invention also provides another technical solution: a mobile phone film assembly for use in any of the above-mentioned film applicators, wherein the mobile phone film structure includes a mobile phone film, a release film is provided on one side of the mobile phone film, a pull-out label is provided on the side of the release film away from the mobile phone film, a positioning film is provided on the other side of the mobile phone film, a left positioning protrusion and a right positioning protrusion are respectively provided on the left and right sides of the positioning film, the left positioning protrusion is provided with a left positioning hole, and the right positioning protrusion is provided with a right positioning hole.

[0016] The beneficial effects of this invention are: The technical solution of this invention involves setting a screen receiving groove in the base to accommodate a mobile phone screen and a screen protector. A left groove, a right groove, a left positioning post, and a right positioning post are provided. One side of the screen protector is glued with a positioning film, so that after the screen protector is placed in the screen receiving groove, it is fixed to the left and right grooves by the positioning film, thus securing the screen protector in the screen receiving groove. The other side of the screen protector is glued with a release film, with one side of the release film facing upwards and the other side of the positioning film facing downwards and abutting against a pad. At the front opening, a label on the release film is bent and extended to the pull-out opening. The mobile phone screen is placed face down in the screen receiving groove. The extended label portion of the release film is pulled out from the pull-out opening until the screen protector and the mobile phone screen are completely adhered and bonded. The pads serve several purposes. First, they ensure a more even fit between the screen protector and the phone screen when placed into the screen holder, preventing unevenness that could affect the application. Second, without pads, placing the screen protector directly into the holder can cause the edges to scrape against the inner wall of the holder, resulting in jamming when pulling it out. The pads make this process smoother and prevent jamming. Furthermore, the pads allow for some movement between the screen protector and the phone screen during the release process, providing sufficient space for easy removal. Additionally, the pads create a height difference between the two ends of the phone by pressing the end furthest from the release opening, allowing for a slight tilt. This helps adjust the angle as the screen protector gradually adheres to the phone screen, effectively removing air bubbles and resulting in a better fit. With its simple structure and easy operation, it requires no help from professional screen protectors and no strong hands-on skills; ordinary consumers can operate it. The screen protector is accurately positioned, has good air venting effect, and is not prone to air bubbles. It is also inexpensive and has a broad market prospect. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-7As shown, this embodiment of the invention provides a screen protector applicator, including a base 100. The base 100 is provided with a screen receiving groove 11. A left side groove 12 and a right side groove 13 are respectively provided on the left and right sides of the screen receiving groove 11. A front opening 14 is provided on the front side of the screen receiving groove 11, and a pull-out opening 15 is provided on the rear side of the screen receiving groove 11. A pad 16 is provided in the middle of the screen receiving groove 11. A left positioning post 121 is provided in the left side groove 12, and a right positioning post 131 is provided in the right side groove 13. Specifically, the pad 16 can be glued to the bottom surface of the screen receiving groove 11, or it can be integrally formed and fixed to the bottom surface of the screen receiving groove 11. The pad 16 can be an elastic pad 16 or a non-elastic pad 16, and the pad 16 can be a foam pad. The pad 16 can be fixed to the bottom of the screen receiving groove 11 by adhesive, or it can be integrally injection molded between the pad 16 and the base 100.

[0027] The technical solution of this invention involves providing a screen receiving groove 11 in the base 100 to accommodate a mobile phone screen and a screen protector 41. By providing a left side groove 12, a right side groove 13, a left positioning post 121, and a right positioning post 131, and by attaching a positioning film 43 to one side of the screen protector 41, the screen protector 41 is fixed to the left side groove 12 and the right side groove 13 by the positioning film 43 after being placed in the screen receiving groove 11. This secures the screen protector 41 within the screen receiving groove 11. On the other side of the film 41, a release film 42 is glued, with one side of the release film 42 facing upwards and the other side of the positioning film 43 facing downwards and abutting against the pad 16. At the front opening 14, the label on the release film 42 is bent and extended to the pull-out opening 15. The mobile phone screen is placed face down in the screen receiving groove 11. The part of the label that extends out of the release film 42 is pulled out from the pull-out opening 15 so that the release film 42 is pulled out from the pull-out opening 15 until the mobile phone film 41 is completely adhered to the mobile phone screen. The pad 16 serves two purposes: firstly, it ensures a more even fit between the screen protector 41 and the phone screen when placed into the screen receiving groove 11, preventing unevenness that could affect the application. Secondly, without the pad 16, placing the screen protector 41 directly into the screen receiving groove 11 could cause the edge of the release liner 42 to scrape against the inner wall of the groove 11, resulting in jamming. The pad 16 makes pulling out the release liner 42 smoother and prevents jamming. Furthermore, the pad 16 ensures that the screen protector 41 remains level during the pulling out process. Both the release film 42 and the mobile phone screen have a certain amount of movable space, providing sufficient space for the release film 42 to be pulled out, making it easier to pull out the release film 42. On the other hand, the pad 16 is set so that during the process of pulling out the release film 42, by pressing the end of the mobile phone away from the pull-out opening 15, there is a height difference between the two ends of the mobile phone, that is, the mobile phone has a certain tilt. This makes it easier to adjust the angle when pulling out the release film 42 while the mobile phone film 41 is gradually adsorbed and attached to the mobile phone screen, so as to more fully remove air bubbles and make the adhesion between the mobile phone film 41 and the mobile phone screen better. With its simple structure and easy operation, it requires no help from professional screen protectors and no strong hands-on skills; ordinary consumers can operate it. The screen protector is accurately positioned, has good air venting effect, and is inexpensive, with broad market prospects.

[0028] In some embodiments, the pad 16 has a strip-shaped structure, with a length of 50mm to 140mm, a width of 5mm to 40mm, and a height of 0.5mm to 4mm. One or more pads 16 are provided. Specifically, one or more pads 16 are provided. The pads 16 are preferably rectangular, preferably one in number, and preferably have a length of 120mm or 110mm, a width of 1.5mm, and a height of 3mm. These preferred dimensions ensure optimal interaction between the screen protector 41 and the phone screen.

[0029] In some embodiments, the device further includes several sets of positioning members 2, each set having four positioning members 2. The base 100 is provided with a rectangular groove 1, and the four positioning members 2 are detachably connected to the four corners of the rectangular groove 1, forming the screen receiving groove 11 between the four positioning members 2. Several sets of positioning members 2 are designed, each set corresponding to a mobile phone model on the market, to increase the applicability of this screen protector, making it suitable for positioning and applying screen protectors to various mobile phone models, thus achieving a universal screen protector application function. Specifically, each mobile phone model corresponds to a set of positioning components 2. When applying a screen protector to a different mobile phone model, the screen receiving slot 11 formed by the set of positioning components 2 corresponding to the previous mobile phone is not compatible with the next mobile phone. Therefore, by replacing the set of positioning components 2 corresponding to the next mobile phone, a screen receiving slot 11 that is compatible with the next mobile phone can be formed, thereby realizing the universal screen protector function. That is, when applying a screen protector to different mobile phones, only the corresponding set of positioning components 2 needs to be replaced, effectively avoiding the problem of frequently changing the screen protector applicator.

[0030] In some embodiments, any one of the four positioning members 2 is a right-angled trapezoidal structure, and the inclined waist of the right-angled trapezoidal structure has a recessed R-corner portion 211. The bottom surface of any one of the positioning members 2 is also provided with a positioning hole 212. Each of the four corners of the rectangular groove 1 is provided with a stop positioning post 17, which is inserted into the positioning hole 212 so that the four positioning members 2 are respectively fixed to the four corners of the rectangular groove 1. Specifically, the R-corner portion 211 is adapted to the four R-corners of the mobile phone film 41, i.e., the four R-corners of the mobile phone. This further improves applicability to different mobile phone models for film application, further strengthens film application positioning, and further improves the film application effect.

[0031] In some embodiments, the four positioning members 2 are respectively the upper left positioning member 21, the lower left positioning member 22, the upper right positioning member 23, and the lower right positioning member 24, and the four corners of the rectangular groove 1 are respectively the upper left corner 111, the lower left corner 112, the upper right corner 113, and the lower right corner 114. The upper left positioning member 21 is fixedly placed at the upper left corner 111, the lower left positioning member 22 is fixedly placed at the lower left corner 112, the upper right positioning member 23 is fixedly placed at the upper right corner 113, and the lower right positioning member 24 is fixedly placed at the lower right corner 114. The gap between the upper left positioning member 21 and the lower left positioning member 22 forms the left side groove 12, and the gap between the upper right positioning member 23 and the lower right positioning member 24 forms the right side groove 13. This design further improves applicability to different mobile phone models and enhances the positioning for screen protector application, thus improving the overall effect.

[0032] In some embodiments, the system further includes a plurality of positioning frames. The base 100 is provided with a rectangular groove 1, and any one of the positioning frames is embedded in the rectangular groove 1. The screen receiving groove 11 is disposed in the positioning frame. Specifically, different mobile phone models correspond to different positioning frames. Preferably, the upper left positioning member 21, the lower left positioning member 22, the upper right positioning member 23, and the lower right positioning member 24 are respectively located at the four corners of the positioning frame, that is, the four positioning members 2 are connected by the frame of the positioning frame. This allows for faster replacement of the positioning frame when changing to different mobile phone models, thereby achieving a universal mobile phone screen protector function and effectively avoiding the problem of frequently changing the screen protector applicator when applying screen protectors to different mobile phones.

[0033] In some embodiments, the screen receiving slot 11 is provided with a press-to-remove hole 18. Specifically, the press-to-remove hole 18 allows for easier removal of the phone from the screen receiving slot 11 after the screen protector is applied. This further improves usability, thereby enhancing application efficiency and user experience.

[0034] In some embodiments, the front opening 14 is provided with a front positioning post 141. Specifically, this further enhances the film positioning to further improve the film application effect.

[0035] In some embodiments, the device further includes a support rod 3 and a pin 32. One end of the support rod 3 is provided with a support rod hole 31. The side of the base 100 is provided with a first support rod connection port 33. The back of the screen receiving groove 11 has a protruding second support rod connection port 34. The end of the second support rod connection port 34 near the first support rod connection port 33 is provided with a support rod limiting part 35. The end of the support rod 3 near the support rod hole 31 is located between the first support rod connection port 33 and the second support rod connection port 34. The pin 32 is sequentially inserted through the first support rod connection port 33, the support rod hole 31, and the second support rod connection port 34. Specifically, by rotating the support rod 3 to a certain angle until the support rod 3 abuts against the support rod limiting part 35, the length direction of the support rod 3 forms a certain angle with the projection of the back of the base 100, so that the support rod 3 supports the base 100. The mobile phone is then placed into the screen receiving groove 11, thereby enabling the screen protector applicator to be used as a mobile phone support holder, further increasing its applicability and achieving multiple uses in one device. With low manufacturing costs and high practicality, the screen protector can also function as a phone stand after application. Alternatively, it can be glued to the back of the screen receiving slot 11 using an adhesive bracket, allowing the screen protector applicator to support the phone and further enhancing its applicability and user experience.

[0036] In some embodiments, a mobile phone film 41 is a mobile phone film 41 assembly 4 used in a screen protector as described in any one of the above embodiments. The mobile phone film 41 structure includes a mobile phone film 41, a release film 42 is provided on one side of the mobile phone film 41, a pull-out label 421 is provided on the side of the release film 42 away from the mobile phone film 41, and a positioning film 43 is provided on the other side of the mobile phone film 41. A left positioning protrusion 431 and a right positioning protrusion 432 are respectively provided on the left and right sides of the positioning film 43. The left positioning protrusion 431 is provided with a left positioning hole 4311, and the right positioning protrusion 432 is provided with a right positioning hole 4321. Specifically, the screen protector positioning is further enhanced to further improve the screen protector application effect.

[0037] In use, the mobile phone film 41 (a component 41 of the film) is placed into the screen receiving groove 11, with the release film 42 facing upwards and the positioning film 43 facing downwards. The left positioning protrusion 431 is placed into the left side groove 12, and the left positioning post 121 is inserted into the left positioning hole 4311. Simultaneously, the right positioning protrusion 432 is placed into the right side groove 13, and the right positioning post 131 is inserted into the right positioning hole 4321. The front side of the positioning film 43 is also provided with a front positioning protrusion, which has a front positioning hole 212. The front positioning protrusion is placed in the front opening 14, and the front positioning post 141 is inserted into the front positioning hole 212. The pull-out label 421 is located on the release film 42 near the front positioning protrusion. On one side, bend the pull tab 421 until the end of the pull tab 421 is inserted into the pull opening 15. Place the phone screen face down into the screen receiving slot 11. Press the end of the back of the phone away from the pull opening 15 with one hand. At this time, because the pad 16 is compressed, the end of the phone being pressed will drop slightly, so that the phone screen and the screen protector 41 are at a certain angle. With the other hand, pull the part of the pull tab 421 that is protruding from the pull opening 15 until the pull tab 421 pulls the release film 42 out of the pull opening 15, so that the screen protector 41 and the phone screen are adhered to each other. Because the side of the release film 42 that is adhered to the screen protector 41 has an electrostatic effect, the release film 42 will attract the dust on the phone screen and bring the dust out from the pull opening 15 when it is pulled out. In addition, the release film 42 can be equipped with an extended label. The pull-out label 421 on the release film 42 can be made into a shorter size. When in use, the pull-out label 421 can be extended by sticking the extended label adhesive to the pull-out label 421, so that the release film 42 can be pulled out at the pull-out opening 15.

[0038] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0039] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
