[0001] The present invention relates to the technical field of screen film application, and in particular to a film application auxiliary tool and a film application method. Background Art

[0002] With the rapid development of people's lives, electronic products such as mobile phones, smart watches, and tablets have become a necessary tool for everyone. Screen protectors are a kind of plastic film attached to the screen of electronic products. They can effectively cushion the impact, prevent the screen from bursting, or prevent the glass panel from breaking and scattering due to accidental impact of electronic products, reduce the hidden damage of the glass panel, and ensure the safety of users; they can also maintain the gloss and texture of the screen and improve the surface hardness.

[0003] In existing film application methods, such as mobile phone film application, the phone to be filmed is placed in a film application device and fixed, and then the film is manually applied to the phone screen after being aligned. However, due to the manual operation during the film application process, the phone screen, which occupies a large horizontal area, is first installed in the film application device and then restrained to prevent the phone from moving. However, the film is often not accurately restrained due to the instability of manual operation, which can easily lead to the problem of incorrect film application position.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

DETAILED DESCRIPTION

[0043] The present invention provides a film application auxiliary tool and a film application method. To make the objectives, technical solutions, and effects of the present invention more clear and explicit, the present invention is described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0044] The specific structure of this embodiment is as follows:

[0045] like Figure 1As shown, this embodiment proposes a film-applying auxiliary tool for applying film to a terminal 100 to be applied with film. The terminal 100 to be applied with film can be a mobile phone, a tablet computer, etc. In this embodiment, a mobile phone is used as an example of the terminal 100 to be applied with film for structural description. When the mobile phone is placed in the film-applying auxiliary tool, the horizontal up and down directions of the mobile phone are the up and down directions described in the structure of this embodiment, and the width direction of the mobile phone is the left and right direction. The direction perpendicular to the left and right directions in the horizontal plane is the front and back direction. This film-applying auxiliary tool specifically includes: a support base 200, and a plurality of elastic film clamping members 300. An accommodating inner cavity 210 is provided in the support base 200, and a pressing groove 211 is provided on the inner wall surface of the accommodating inner cavity 210. The upper part of the accommodating inner cavity 210 is an opening, and the pressing groove 211 is provided on the bottom surface opposite to the opening, so that the support base 200 forms a box body. A plurality of elastic film clamping members 300 are disposed in the accommodating cavity 210 and can be distributed along a circumference of the accommodating cavity 210 or around a plurality of side surfaces of the accommodating cavity 210, such as Figure 3 As shown, in this embodiment, the elastic film clamping members 300 can be specifically set to 8, and the 8 elastic film clamping members 300 are distributed in pairs on the front, back, left, and right sides. It can also be set to other numbers, such as 6. Figure 2 、 Figure 3 As shown, the opposing elastic film clamping members 300 are deformed toward the outside of the accommodating cavity 210 by the compression of the diaphragm 110 to clamp the diaphragm 110. Thus, when the diaphragm 110 is inserted into the accommodating cavity 210, it compresses the elastic film clamping members 300 and enters the film clamping position. The diaphragm 110 is clamped and embedded by the multiple elastic film clamping members 300, accurately retaining the diaphragm 110 in the middle of the accommodating cavity 210. The accommodating cavity 210 is used to accommodate a mobile phone. After the diaphragm 110 is placed, the mobile phone is placed in the accommodating cavity 210 and retained, with the mobile phone located on the side of the diaphragm 110 facing away from the pressing groove 211.

[0046] like Figure 1 、 Figure 2 、 Figure 3As shown, in the above scheme, by placing the diaphragm 110 in the accommodating cavity 210 in the support base 200, the diaphragm 110 squeezes the elastic film clamping member 300 during the placement process and enters the film clamping position, so that the diaphragm 110 is clamped by multiple elastic film clamping members 300, and the diaphragm 110 is accurately limited to the middle position of the accommodating cavity 210. When the diaphragm 110 is limited, the lower release film on the diaphragm 110 can be manually torn off directly, and the terminal 100 (mobile phone) to be attached with the film is placed in the accommodating cavity 210. The accommodating cavity 210 limits the terminal 100 to be attached with the film and makes the terminal 100 to be attached with the film face the top of the diaphragm 110; flip the support base 200 so that the pressing groove 211 faces From above, pressure is applied to the film 110 in the pressing groove 211, so that the film 110 is attached to the terminal 100 to be pasted, and then the terminal 100 to be pasted is taken out from the accommodating inner cavity 210, and the upper release film of the film 110 is torn off; thereby completing the entire film pasting process. When using the film pasting auxiliary tool during the film pasting process, the film 110 is first placed, and the elastic film clamping parts 300 at multiple locations quickly center and limit the film 110, and then the terminal 100 (mobile phone) to be pasted is placed for limiting, thereby achieving more accurate positioning of the film 110 and the terminal 100 (mobile phone) to be pasted, ensuring that the film pasting position is right on the screen of the terminal 100 (mobile phone) to be pasted, greatly improving the accuracy and success rate of the film pasting.

[0047] When this convenient film case is applied to a corresponding mobile phone model, for example, the thickness of the film 110 (tempered film) varies. Therefore, due to the elasticity of the elastic film retaining member 300, the film retaining member 300 can form an appropriate gap to accommodate all tempered films that match this model of mobile phone. In addition, since the edge of the mobile phone has a non-display area, the size of the film edge on the non-display area varies, resulting in the film 110 (tempered film) having different sizes on the horizontal plane. Due to the elasticity of the elastic film retaining member 300, it can form an appropriate gap to accommodate tempered films of different sizes on the horizontal plane.

[0048] like Figure 3 、 Figure 4As shown, the elastic film clamping member 300 in this embodiment specifically includes: an elastic connecting plate 310 and a hook portion 320. One end of the elastic connecting plate 310 is connected to the support seat 200, and the other end is movably arranged. The hook portion 320 is connected to the other end of the elastic connecting plate 310. The hook portion 320 is located inside the accommodating cavity 210. For the convenience of structural description, the side facing the center of the accommodating cavity 210 is the inner side, and the side away from the center of the accommodating cavity 210 is the outer side. An opening is provided on the hook portion 320 so that the edge of the diaphragm 110 can be embedded through the opening; the opening of the hook portion 320 is set toward the inner side of the accommodating cavity 210. When the diaphragm 110 is mounted on the elastic film clamp 300, the diaphragm 110 is first pressed downward against the hook portion 320. The squeezing force causes the elastic connecting plate 310 to deform and move outward, thereby increasing the distance between the opposing hook portions 320. This allows the diaphragm 110 to enter the hook portions 320 through the openings of the hook portions 320. The elastic connecting plate 310 then returns to its original position due to the elastic force, thereby retaining the diaphragm 110 in place through the hook portions 320. The provision of multiple hook portions 320 allows the diaphragm 110 to be more securely secured, and the diaphragm 110 is less likely to loosen after being retained.

[0049] like Figure 3 、 Figure 4 As shown, the hook portion 320 in this embodiment specifically includes: a bearing surface 321 and a limiting protrusion 322. The bearing surface 321 is located at the bottom, and the limiting protrusion 322 is located at the top. A locking groove 323 is formed between the limiting protrusion 322 and the bearing surface 321. The inward opening of the locking groove 323 is the opening of the hook portion 320. When the hook portion 320 is engaged with the diaphragm 110, the edge of the diaphragm 110 is located in the locking groove 323. The bearing surface 321 is used to support the diaphragm 110. The limiting protrusion above the diaphragm 110 limits the diaphragm 110, preventing it from escaping from the locking groove 323. In addition, the left and right side walls of the locking groove 323 abut against the edges of the diaphragm 110, which can also slightly exert force on the edges of the diaphragm 110, thereby preventing the diaphragm 110 from loosening within the surrounding hook portion 320. In addition, the diaphragm 110 is slightly stressed, and the plane of the diaphragm 110 can be slightly deformed. One side of the diaphragm 110 is limited by the supporting table 321, so that the diaphragm 110 is deformed into a bow shape toward the screen of the mobile phone, so that the diaphragm 110 is closer to the center of the screen, and the positions on the left and right sides are slightly farther. When the diaphragm 110 is subsequently squeezed and attached, the middle is attached first, and the outer edges are attached later, which is more conducive to exhaust.

[0050] In this embodiment, the surface (lower surface) of the limiting protrusion 322 facing the supporting table 321 is a spherical arc surface. The spherical arc surface makes point contact with the surface of the diaphragm 110, minimizing the contact between the lower surface of the limiting protrusion 322 and the diaphragm 110, thereby minimizing the impact of the glue on the diaphragm 110. The spherical arc surface has a small glue pressing surface, which can achieve a relatively perfect film application on the mobile phone screen. Figure 2 、 Figure 6 As shown, when the film 110 is attached, its surface has a lower release film, which needs to be torn off before the film can be applied. Therefore, a spherical arc surface is used, so that the lower release film can be detached along the contour of the spherical arc surface during the detachment process, and will not be stuck due to excessive pressure from the limiting protrusion 322. Moreover, during the tearing process of the lower release film, the lower release film at the tearing position can easily squeeze the hook portion 320, and the hook portion 320 in the tearing position immediately engages the film 110. Therefore, the two card points on the left and right sides are detached, and the other two card points can still hold the film 110. The film 110 is a very hard rigid film, which can keep the film 110 stuck at multiple card points, so that the film 110 will not loosen or fall off. The above advantages greatly increase the speed and success rate of detaching the lower release film.

[0051] like Figure 2 、 Figure 6 As shown, the surface (lower surface) of the limiting protrusion 322 facing the support platform 321 is spherically curved, so that the left and right width of the surface of the engaging groove 323 facing inward is smaller, while the left and right width facing outward is larger. When engaging diaphragms 110 of different thicknesses, an adaptive fit is formed at the edges of the diaphragms 110 of different thicknesses, and diaphragms 110 of different thicknesses can be stably engaged.

[0052] like Figure 2 、 Figure 4 As shown, in this embodiment, the limiting protrusion 322 is provided with an inclined surface 324 on the surface (upper surface) facing away from the supporting platform 321. The inclined surfaces 324 gradually approach inward from top to bottom. The limiting protrusions 322 on opposite sides are arranged in a mirror image. For example, the upper surfaces of the limiting protrusions 322 on the left and right sides are both provided with inclined surfaces 324. A tapered opening is formed between the mirror image and opposing inclined surfaces 324. Therefore, when the diaphragm 110 is pressed against the hook portion 320, the diaphragm 110 is guided by the inclined surface 324, so that the diaphragm 110 is smoothly pressed against the limiting protrusion 322 under the guidance of the inclined surface 324. The limiting protrusion 322 can also generate downward and outward components of the extrusion force through the inclined surface 324. This makes it easier for the elastic connecting plate 310 to deform under the force, and the hook portion 320 to be squeezed open, effectively reducing damage to the diaphragm 110 caused by the extrusion.

[0053] like Figure 4As shown, in this embodiment, a clearance groove 220 is formed on the side wall of the accommodating cavity 210, and the elastic connecting plate 310 is located in the clearance groove 220. The provision of the clearance groove 220 separates the elastic connecting plate 310 from the outer wall of the support base 200, thereby ensuring the elasticity of the elastic connecting plate 310, allowing the elastic connecting plate 310 to have stable deformation ability and not easily break.

[0054] like Figure 2 、 Figure 3 、 Figure 4 As shown, the elastic connecting plate 310 in this embodiment is U-shaped, with one end of the U-shaped elastic connecting plate 310 fixedly connected to the inner wall of the accommodating cavity 210, and the other end fixedly connected to the hook portion 320. The U-shaped elastic connecting plate 310 has stable deformation ability, thereby ensuring the elasticity of the elastic connecting plate 310.

[0055] like Figure 2 、 Figure 4 As shown, in this embodiment, a concave annular groove 212 is provided on the bottom surface of the accommodating inner cavity 210, and the concave annular groove 212 extends through the U-shaped elastic connecting plate 310. A convex annular platform 230 is formed on the surface of the support base 200 at a position corresponding to the concave annular groove 212 at the bottom surface of the accommodating inner cavity 210. This ensures the consistency of the wall thickness of the support base 200. The concave annular groove 212 extends through the U-shaped elastic connecting plate 310, thereby lengthening the elastic connecting plate 310. That is, the U-shaped depth of the U-shaped elastic connecting plate 310 can be deepened by the concave annular groove 212, thereby enhancing the deformation ability of the U-shaped elastic connecting plate 310 and providing a sufficiently strong structure to ensure that it is not easily unable to return to its original position due to large deformation when squeezed.

[0056] like Figure 2 、 Figure 3 、 Figure 4As shown, a limiting portion 240 is provided on the side wall surface of the accommodating inner cavity 210 in this embodiment, and a limiting step 241 is provided on the limiting portion 240. The limiting step 241 has a side wall and a lower limiting surface 242. When the mobile phone is placed in the accommodating inner cavity 210, the side wall of the limiting step 241 abuts against the side of the mobile phone, and the lower limiting surface 242 of the limiting step 241 abuts against the edge of the side of the mobile phone with the screen, thereby achieving abutment and limiting of the mobile phone. Specifically, there are 8 limiting parts 240, that is, 2 limiting parts 240 are respectively provided on the front, rear, left and right side walls of the accommodating cavity 210 to position the mobile phone. The side wall surfaces of the limiting steps 241 of the limiting parts 210 arranged opposite to each other are stuck around the mobile phone to fix it in the horizontal direction. The lower limiting surface 242 of the limiting step 241 presses the surface edge of the mobile phone screen. Due to the gravity of the mobile phone, the mobile phone is limited in the vertical direction. Since the diaphragm has been limited and fixed in the accommodating cavity 210 before, the diaphragm and the mobile phone are positioned extremely accurately. The side wall of the limiting step 241 is located on the outside of the hook portion 320, so that the hook portion 320 can engage the diaphragm 110 with a smaller area, while the limiting step 241 limits the mobile phone with a larger area; when the diaphragm 110 is installed, the limiting step 241 will not interfere with the diaphragm 110, so that the diaphragm 110 is smoothly limited, and the lower limiting surface 242 of the limiting step 241 is higher than the surface of the limiting protrusion 322 of the hook portion 320. Similarly, the hook portion 320 will not interfere with the installation of the mobile phone, so that the diaphragm 110 is smoothly limited.

[0057] In addition, to facilitate the flipping of the support base 200, handles 250 are protruding from the front and rear sides of the support base 200. By providing the handles 250, it is convenient for the user to hold the support base 200 during operation, which facilitates the flipping of the support base 200.

[0058] like Figure 5 As shown, based on the above structure, the present application also proposes a film-attaching method, which includes the following steps:

[0059] Step S100: placing the diaphragm in the accommodating cavity of the support seat, and locking the diaphragm with a plurality of elastic film-locking members.

[0060] Step S110 : applying a pulling force through the pulling piece on the membrane to separate the lower release film body from the membrane.

[0061] Step S120: Place the terminal to be film-attached in the accommodating cavity, facing the top of the film.

[0062] Step S130: flip the support base.

[0063] Step S140 : applying pressure to the film in the pressing groove so that the film is attached to the terminal to be attached.

[0064] Specifically: press the tempered film with your finger, the tempered film pops out of the card slot and fits the phone screen, and automatically vents.

[0065] Step S150: Take out the terminal to be laminated from the accommodating cavity and tear off the upper release film of the film.

[0066] Therefore, the above-mentioned film pasting auxiliary tool is used and the above-mentioned method is used to implement film pasting. First, a relatively small film sheet is placed, and multiple elastic film clamps are used to quickly center and limit the film sheet. Then, the terminal (mobile phone) to be pasted with the film is placed to limit the position, thereby achieving more accurate positioning of the film sheet and the terminal (mobile phone) to be pasted with the film, ensuring that the film pasting position is right on the screen of the terminal (mobile phone) to be pasted with the film, and greatly improving the accuracy and success rate of the film pasting.

[0067] like Figure 6 、 Figure 7 As shown, based on the structure of the above-mentioned film-sticking auxiliary tool, in another solution of this embodiment, a film-tearing groove 260 is provided on one side wall of the support base 200, and the film-tearing groove 260 is connected to the accommodating cavity 210. Figure 8 、 Figure 9 As shown, since the lower limit surface 242 of the limit step 241 is higher than the surface of the limit protrusion 322 of the hook portion 320, there is a certain gap between the diaphragm 110 limited in the accommodating cavity 210 and the mobile phone screen, and the tearing groove 260 docks with the gap. When the diaphragm 110 is in a position of about 100, the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm 110 is clamped in a position where the diaphragm

[0068] like Figure 7 、 Figure 9As shown, two fixed limiting portions 270 are provided on the inner wall of the accommodating cavity 210 on one side facing the film tearing groove 260 , so that multiple elastic film clamping parts 300 and fixed limiting portions 270 are distributed around the accommodating cavity 210 . In the specific structure, elastic film clamping parts 300 are respectively provided on the left and right sides of the accommodating inner cavity 210 and on the side opposite to the film tearing groove 260, and two elastic film clamping parts 300 are provided on each side to clamp the diaphragm 110, and on the side facing the film tearing groove 260, the front end or the rear end (the end facing the film tearing groove 260) of the diaphragm 110 is limited by the fixed limiting part 270, thereby achieving six spherical limiting protrusions 322 and two fixed limiting parts 270 with limiting steps at the rear end to fix the diaphragm 110 (tempered film) together to achieve precise positioning; the function of the two fixed limiting parts 270 with limiting steps is to prevent the diaphragm 110 from moving when the pulling piece 113 drives the lower release film body 112 to be pulled, thereby ensuring the stability of the tempered film during the pulling process of the pulling piece 113. The elastic film clamping member 300 with the spherical limiting protrusion 322 serves to facilitate the insertion of the diaphragm 110 and, in the process of pressing the diaphragm 110 onto the screen of the mobile phone, enables the edge of the diaphragm 110 to slide out of the clamping slot 323 along the spherical contour, thereby facilitating the attachment process of the diaphragm 110.

[0069] The support seat 200, the plurality of elastic clamping membrane members 300, the limiting portion 240 and the fixed limiting portion 270 in this embodiment are integrally formed. No other components need to be assembled during use. The structure is simple, ingenious and practical.

[0070] like Figure 10 As shown, based on the second structural solution of this embodiment, the present application also proposes another film-attaching method, which includes the following steps:

[0071] Step S200: placing the diaphragm in the accommodating cavity of the support seat, and locking the diaphragm with a plurality of elastic film-locking members.

[0072] Step S210: Place the terminal to be film-attached in the accommodating cavity, facing the top of the film.

[0078] In summary, the present application proposes a film-sticking auxiliary tool and a film-sticking method, wherein the diaphragm is placed in the accommodating cavity in the support seat, and the diaphragm squeezes the elastic film-sticking part during the placement process and enters the film-sticking position, so that the diaphragm is clamped by multiple elastic film-sticking parts, and the diaphragm is accurately limited to the middle position of the accommodating cavity. When the diaphragm is limited, the lower release film on the diaphragm can be manually torn off, and the terminal (mobile phone) to be attached with the film is placed in the accommodating cavity. The accommodating cavity limits the terminal to be attached with the film and makes the terminal to be attached with the film face the top of the diaphragm; the support seat is turned over so that the pressing groove faces upward , apply pressure to the diaphragm in the pressing groove, so that the diaphragm is attached to the terminal to be pasted, and then the terminal to be pasted is taken out from the accommodating cavity, and the upper release film of the diaphragm is torn off; thereby completing the entire film pasting process. When using this film pasting auxiliary tool during the film pasting process, first put in a diaphragm with a relatively small area, and multiple elastic film clamps quickly center and limit the diaphragm, and then place the terminal to be pasted (mobile phone) for limiting the position, thereby achieving more accurate positioning of the diaphragm and the terminal to be pasted (mobile phone), ensuring that the film pasting position is right on the screen of the terminal (mobile phone) to be pasted, and greatly improving the accuracy and success rate of the film pasting. Six spherical stoppers and two stoppers with step-shaped retaining elements at the rear end work together to secure the film for precise positioning. The two step-shaped stoppers prevent the film from moving, ensuring the stability of the tempered film during the pulling process. The elastic film retaining element with the spherical stoppers facilitates the insertion of the tempered film and allows the edge of the film to slide out of the retaining slot along the spherical contour during the pressing process. The spherical arc-shaped stoppers allow the lower release film to be released along the contour of the spherical arc without excessive pressure from the stoppers, significantly increasing the speed and success rate of the lower release film release. The tear-off slot allows the film to be removed to remove dust from the surface to be applied. This film application tool can also be used as a packaging box, becoming a selling point for mobile phones and boosting sales. This film-sticking auxiliary tool is an integrated molding device, and no other components need to be assembled when in use. Its structure is simple, ingenious and practical, and its use is convenient, simple and efficient, breaking through the industry thinking and subverting the film-sticking method.
