[0026] The following is an explanation of the implementation methods of the "screen protector customization system and film cutting tool" disclosed in the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual dimensions. It is stated in advance. The following implementation methods will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.
[0027] It should be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.
[0028] See also Figures 1 to 9, which is an embodiment of the present invention. This embodiment discloses a screen protector customization system 1000, which includes a film cutting device 100, a size film 200 suitable for the film cutting device 100, and a cloud server 300 electrically coupled to the film cutting device 100, but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the screen protector customization system 1000 can also omit the cloud server 300 according to actual needs.
[0029] It should be noted that the screen protector customization system 1000 is preferably applied to manufacturers that process mobile phone films, so that the model of the mobile phone can be selected, and the film cutting device 100 performs a cutting operation on the size film 200 to form a corresponding screen protector, thereby achieving the effect of customized film cutting. In other words, the film cutting device that is not in a customized form is different from the screen protector customization system 1000 referred to in this embodiment.
[0030] Furthermore, the size film 200 in this embodiment includes a bottom layer 201, a buffer layer 202, and a use layer 203 sandwiched between the bottom layer 201 and the buffer layer 202. The use layer 203 has a hardening film 2031 and a laminating film 2032 located on opposite sides, and the bottom layer 201 is attached to the laminating film 2032 of the use layer 203, and the buffer layer 202 is attached to the hardening film 2031 of the use layer 203. Furthermore, in order to prevent the size film 200 from having defects such as burrs after being cut, the size film 200 preferably has at least some of the following features, but is not limited thereto. The laminating film 2032 is formed on the hardening film 2031, and the hardening film 2031 has a hardness of at least 6H. The buffer layer 202 includes a first buffer film 202a attached to the hardening film 2031 and a second buffer film 202b attached to the first buffer film 202a. In addition, the bottom layer 201 may be a plate 201a that is cut-proof, or the bottom layer 201 may include the plate 201a and a dust removal film 201b connected between the plate 201a and the laminating film 2032, which is not limited in the present invention.
[0031] The hardness of the hardened film 2031, the hardness of the first buffer film 202a, and the hardness of the second buffer film 202b are decreasing in sequence, and the thickness of the hardened film 2031, the thickness of the first buffer film 202a, and the thickness of the second buffer film 202b are decreasing in sequence. In this embodiment, the thickness of the second buffer film 202b is 75% to 90% of the thickness of the first buffer film 202a, and the thickness of the first buffer film 202a is 60% to 75% of the thickness of the hardened film 2031. In other words, the sum of the thickness of the first buffer film 202a and the thickness of the second buffer film 202b is 95% to 105% of the thickness of the laminating film 2032, and the thickness of the hardened film 2031 is 75% to 90% of the thickness of the laminating film 2032.
[0032] For example, the first buffer film 202a is made of a soft material and its thickness may be between 75 microns (μm) and 90 microns, the second buffer film 202b may be made of a thickness between 95 μm and 110 μm, the hardening film 2031 may be made of a thickness between 130 μm and 190 μm, the laminating film 2032 may be made of a high-viscosity AB glue and its thickness may be between 150 μm and 225 μm. The plate 201a may be made of a material between 175 μm and 225 μm, and the dust removal film 201b may be white and its thickness may be between 100 μm and 150 μm.
[0033] In addition, the size film 200 in this embodiment also has an identification code 2021 (such as a QR code) located on the buffer layer 202, and the identification code 2021 can be directly printed on the buffer layer 202, or attached to the buffer layer 202 separately, and the utility model is not limited to the above. For example, in other embodiments not shown in the utility model, the number of layers of the size film 200 can also be adjusted according to actual needs (such as omitting the bottom layer 201).
[0034] Furthermore, the size film 200 (or the hardening film 2031) is limited to have a hardness of at least 5H (e.g., pencil hardness), and the area of the size film 200 is larger than the screen area of any mobile phone on the market. Accordingly, any film cutting device used only for cutting soft films is different from the screen protector customization system 1000 referred to in this embodiment.
[0035] Furthermore, the material of the size film 200 can be adjusted and changed according to actual needs. For example, the size film 200 can be a flexible protective film and made of, for example, polyethylene terephthalate (PET), recycled polyethylene terephthalate (RPET), thermoplastic polyurethane resin (TPU), or recycled thermoplastic polyurethane resin (RTPU), but the present invention is not limited thereto.
[0036] Furthermore, in order to be able to cut the size film 200 with a hardness of at least 5H, the film cutting device 100 is equipped with a film cutting tool 1 with a specific structural design. In other words, the structural design of the film cutting tool 1 is the key factor for the film cutting device 100 to be able to cut the size film 200 with a hardness of at least 5H (e.g., this embodiment can achieve a hardened film 2031 with a hardness of 7H and simultaneously avoid the generation of burrs on the bonding film through the cooperation of the film cutting tool 1 and the size film 200). Accordingly, this embodiment first introduces the film cutting tool 1 below, and then describes other components of the film cutting device 100.
[0037] like Figures 2 to 7 As shown, the film cutting tool 1 is defined with a transverse reference plane P1 perpendicular to its long axis direction L and a longitudinal reference plane P2 perpendicular to the transverse reference plane P1. In this embodiment, the film cutting tool 1 includes a mounting section 11, a support section 12 connected to the mounting section 11, and a cutting section 13 connected to the support section 12. The cutting section 13 is integrally formed and connected to the support section 12, and the support section 12 is welded and fixed to the mounting section 11. In other words, the film cutting tool 1 is a two-piece joint structure, and the film cutting tool 1 is preferably a single-piece structure excluding integral forming.
[0038] To put it another way, the mounting section 11 and the cutting section 13 are respectively connected to opposite ends of the supporting section 12, and the supporting section 12 is connected to approximately the center of the end surface of the mounting section 11, while the cutting section 13 is offset relative to the end surface of the supporting section 12, but not limited to this.
[0039] The support section 12 has a ring side surface in the shape of a circular ring. The cutting section 13 has a side plane 131, a side arc surface 132 connected to the side plane 131, a primary blade surface 134 connected to the side plane 131, and a main blade surface 133 connected to the secondary blade surface 134 and the side arc surface 132. The side arc surface 132 is cut flush with the ring side surface of the support section 12, the main blade surface 133 is plane-shaped, and the main blade surface 133 is connected to the secondary blade surface 134 to form a main edge 13a, and the main edge 13a is located on the longitudinal reference plane P2, and the secondary blade surface 134 is elongated and parallel to the main edge 13a.
[0040] The side plane 131 and the longitudinal reference plane P2 have an oblique angle σ2 between 1 and 3 degrees, the main edge 13a and the transverse reference plane P1 form a first angle σ1 between 43 and 47 degrees, and the main edge 13a has a first height H1 between 0.98 mm and 1.08 mm corresponding to the long axis direction L. In addition, the width W134 of the secondary blade surface 134 is between 0.01 mm and 0.03 mm, and the area of the main blade surface 133 is at least 5 times the area of the secondary blade surface 134.
[0041] Accordingly, the film cutting tool 1 passes through the cutting section 13 under certain conditions to facilitate cutting the size film 200. In addition, in order to make the film cutting tool 1 more easily cut the size film 200, the film cutting tool 1 preferably has at least some of the following features, but is not limited thereto.
[0042] Furthermore, the maximum thickness T13 between the side plane 131 and the side arc surface 132 is 40% to 55% of the minimum outer diameter T12 of the support section 12. Furthermore, the main edge 13a has a tip 131a away from the support section 12 and a top 132a adjacent to the support section 12, and the side arc surface 132 is formed with a secondary edge 13b extending from the tip 131a. The secondary edge 13b has a second height H2 between 4 microns (μm) and 6 microns corresponding to the long axis direction L. Accordingly, the film cutting tool 1 can be more conducive to cutting the size film 200 by having the main edge 13a and the secondary edge 13b with specific conditions, so that the main edge 13a and the secondary edge 13b are matched with each other, and can effectively avoid the size film 200 from generating burrs on the bonding film 2032.
[0043] The side plane 131 and the side arc surface 132 are connected to form a ring side surface of the cutting segment 13 .
[0044] Furthermore, although the film cutting tool 1 is used in the film cutting device 100 in this embodiment, the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the film cutting tool 1 can also be used alone (e.g., sold) or used in combination with other components according to actual needs.
[0045] like Figure 1 , Figure 8 and Fig. 9 As shown, the above is a structural description of the film cutting tool 1, and the following will introduce other components of the film cutting device 100. The film cutting device 100 includes a carrier body 2, a displacement mechanism 3, a processing module 4 and a scanner 5. The displacement mechanism 3, the processing module 4 and the scanner 5 are all installed on the carrier body 2, and the displacement mechanism 3 and the scanner 5 are electrically coupled to the processing module 4.
[0046] Furthermore, the displacement mechanism 3 can move relative to the carrier body 2, and the processing module 4 can be electrically coupled to the displacement mechanism 3 to drive the displacement mechanism 3 to move sequentially along a first cutting path and a second cutting path that are different from each other. The film cutting tool 1 is installed on the displacement mechanism 3 by the installation section 11, so that the film cutting tool 1 can move synchronously with the displacement mechanism 3.
[0047] In addition, the cloud server 300 is electrically coupled to the processing module 4 and the scanner 5, so that when the size film 200 is fixed to the carrier body 2, the scanner 5 can scan the identification code 2021 of the size film 200 to generate a signal, and the cloud server 300 can receive the signal through the processing module 4 to allow the film cutting equipment 100 to perform the cutting operation and identify the material of the size film 200.
[0048] It should be additionally explained that the processing module 4 in this embodiment also includes a touch screen for the user to input the model of the mobile phone to be filmed. Accordingly, the processing module 4 can make the film cutting device 100 perform the corresponding cutting operation according to the model of the mobile phone input by the user, but the utility model is not limited to this. For example, in other embodiments not shown in the utility model, the processing module 4 can also receive a signal from an external device (such as a computer or a user's mobile phone) in other ways to obtain the model of the mobile phone to be filmed.
[0049] When the sizing film 200 is placed in the film cutting device 100 for the cutting operation, the sizing film 200 is fixed to the carrying body 2, and the displacement mechanism 3 is driven by the processing module 4 so that the main blade 13a of the film cutting tool 1 is first cut along the first cutting path relative to the buffer layer 202 and the use layer 203 to form a first contour S1, and then cut along the second cutting path to form a second contour S2 located outside the first contour S1, which has at least one positioning hole 2022.
[0050] As described above, since the film cutting device 100 cuts into the size film 200 through the buffer layer 202 rather than the bonding film 2032 of the use layer 203, it can effectively reduce damage to the adhesive layer of the bonding film 2032 and avoid burrs on the use layer 203.
[0051] It should be further explained that the displacement mechanism 3 can drive the film cutting tool 1 to move relative to the size film 200 along the mutually perpendicular X-axis direction, Y-axis direction and Z-axis direction, and the object to be moved (such as: the film cutting tool 1 or the size film 200) can be adjusted and changed according to actual needs. For example, the film cutting tool 1 can be driven by the displacement mechanism 3 to move along the X-axis direction and the Z-axis direction, and the size film 200 is driven by the displacement mechanism 3 to move along the Y-axis direction, so that the film cutting tool 1 can move relative to the size film 200 along the first cutting path and the second cutting path in sequence.
[0052] Furthermore, after the size film 200 is cut to form the screen protector, the buffer layer 202 has a screen area 2023 and a plurality of positioning areas 2024 separated from the screen area 2023 .
[0053] [Technical effects of the utility model embodiment]

[0055] Furthermore, the film cutting tool disclosed in the embodiment of the utility model can also be equipped with the main edge and the secondary edge with specific conditions (such as: the secondary edge has the second height between 4 microns and 6 microns) so that the main edge and the secondary edge can be matched with each other to be more conducive to cutting the size film with a hardness of at least 5H, and can effectively avoid the generation of burrs on the size film and the bonding film.
