[0027] The following is an explanation of the implementation 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 content 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. Please note in advance. The following embodiments will further explain the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0028] It should be understood that although terms such as "first," "second," and "third" may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. In addition, the term "or" as used herein may include any one or more combinations of the associated listed items, as appropriate.

[0029] See also Figures 1 to 10 , 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 film 200 of a suitable size 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 may omit the cloud server 300 based on actual needs.

[0030] It should be noted that the screen protector customization system 1000 is preferably used by manufacturers that process mobile phone screen protectors. The manufacturer can select a mobile phone model and use the film cutting device 100 to cut the film 200 to form a corresponding screen protector 200a, thereby achieving customized film cutting. In other words, non-customized film cutting devices are different from the screen protector customization system 1000 referred to in this embodiment.

[0031] Furthermore, the size film 200 in this embodiment includes a bottom layer 201, a positioning layer 202, and a use layer 203 sandwiched between the bottom layer 201 and the positioning layer 202. Wherein, the use layer 203 has a protective surface 2031 and a fitting surface 2032 located on opposite sides, and the bottom layer 201 is attached to the fitting surface 2032 of the use layer 203, while the positioning layer 202 is attached to the protective surface 2031 of the use layer 203. In addition, the size film 200 in this embodiment also has an identification code 2021 (such as a QR code) located in the positioning layer 202, and the identification code 2021 can be directly printed on the positioning layer 202 or separately attached to the positioning layer 202. The present invention is not limited to the above. For example, in other embodiments not shown in the present invention, the number of layers of the size film 200 can also be adjusted according to actual needs (such as omitting the bottom layer 201).

[0032] Furthermore, the sizing film 200 (or the use layer 203) is limited to having a hardness of at least 5H (e.g., pencil hardness), and the area of ​​the sizing film 200 is larger than the screen area of ​​any commercially available mobile phone. Therefore, any film cutting device used only for cutting soft films is not the same as the screen protector customization system 1000 referred to in this embodiment.

[0033] 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 to this.

[0034] Furthermore, to enable cutting of the sized film 200 having a hardness of at least 5H, the film cutting apparatus 100 is equipped with a film cutting blade 1 having a specifically designed structure. In other words, the structural design of the film cutting blade 1 is a key factor in enabling the film cutting apparatus 100 to cut the sized film 200 having a hardness of at least 5H. Accordingly, this embodiment will first introduce the film cutting blade 1, followed by a description of the other components of the film cutting apparatus 100.

[0035] like Figures 2 to 7 As shown, the film cutting tool 1 defines a layout reference plane P perpendicular to its long axis L. The film cutting tool 1 is a one-piece, integrally molded structure; that is, the film cutting tool 1 can be formed by machining a metal column. 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.

[0036] 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 the approximate center of the end face of the mounting section 11, while the cutting section 13 is offset relative to the end face of the supporting section 12, but not limited to this.

[0037] The cutting segment 13 has a first side surface 131, a second side surface 132 spaced apart from the first side surface 131, and a blade surface 133 connected between the first side surface 131 and the second side surface 132. The first side surface 131, the second side surface 132, and the blade surface 133 are all planar, and the blade surface 133 is connected to the first side surface 131 to form a main edge 13a. The main edge 13a forms a first angle σ1 between 43 and 47 degrees with the layout reference plane P, and has a first height H1 between 0.98 and 1.08 mm relative to the long axis L.

[0038] Accordingly, the film cutting tool 1 forms the main edge 13a with specific conditions in the cutting section 13 to facilitate cutting the size film 200. In addition, to make it easier for the film cutting tool 1 to cut the size film 200, the film cutting tool 1 preferably has at least some of the following features, but is not limited thereto.

[0039] Specifically, the support segment 12 defines a centerline C parallel to the longitudinal axis L, and a distance D131 between the first side surface 131 and the centerline C is smaller than a distance D132 between the second side surface 132 and the centerline C. A second angle σ2 between the second side surface 132 and the layout reference plane P is formed between the second side surface 132 and the layout reference plane P and is between 91 degrees and 91.5 degrees.

[0040] Furthermore, the main edge 13a has a tip 131a distal from the support section 12 and a top 132a adjacent to the support section 12. The blade surface 133 has a bottom edge 1331 connected to the tip 131a and a top edge 1332 connected to the top 132a. The bottom edge 1331 of the blade surface 133 has a height H1331 ranging from 0.73 mm to 0.77 mm along the longitudinal direction L.

[0041] The cutting segment 13 has a first end surface 134 and a second end surface 135 spaced apart from each other. The first end surface 134 is connected to the first side surface 131, the second side surface 132, and the bottom edge 1331 of the blade surface 133, thereby forming the blade tip 131a. The second end surface 135 is connected to the first side surface 131, the second side surface 132, and the top edge 1332 of the blade surface 133, thereby forming the top end 132a.

[0042] The first side surface 131, the first end surface 134, the second side surface 132 and the second end surface 135 are connected to form a ring shape and are the annular side surface of the cutting segment 13. There is a blade thickness T13 between the first side surface 131 and the second side surface 132, which gradually increases from the first end surface 134 toward the second end surface 135. In other words, the blade thickness T13 gradually increases from the tip 131a toward the top 132a, thereby effectively supporting the main edge 13a. Further, the blade thickness T13 corresponding to the first end surface 134 (that is, the width of the first end surface 134) is preferably 0.26 mm to 0.28 mm (e.g., Figure 6 ), and the blade thickness T13 corresponding to the second end surface 135 (that is, the width of the second end surface 135) is preferably 0.29 mm to 0.31 mm (e.g.: Figure 4 ), but the present invention is not limited thereto.

[0043] The first side surface 131 and the first end surface 134 are connected to form a secondary cutting edge 13b extending from the blade tip 131a. The secondary cutting edge 13b has a second height H2 ranging from 4 microns (μm) to 6 microns along the longitudinal direction L. Accordingly, the film cutting tool 1 can achieve a better fit by having the primary cutting edge 13a and the secondary cutting edge 13b with specific conditions, thereby effectively preventing burrs on the film 200 from forming on the contact surface 2032.

[0044] It should be noted that the film cutting tool 1 is preferably made of tungsten steel or tungsten-containing forged high-speed steel, or the outer surface of the film cutting tool 1 is electroplated with a DLC (Diamond Like Carbon) coating, which combines the high hardness of diamond with the lubricity of graphite and is composed of an amorphous coating of carbon and hydrogen. This coating is preferably produced using a PVD or PACVD process, but the present invention is not limited to this process. For example, the film cutting tool 1 can also be made of other materials or have its outer surface hardened using other treatments.

[0045] Furthermore, although the film cutting tool 1 is described in this embodiment as being used in the film cutting device 100, 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 in conjunction with other components according to actual needs.

[0046] like Figure 1 and Figures 8 to 10 The above is a structural description of the film cutting tool 1. The following describes the 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 mounted on the carrier body 2, and the displacement mechanism 3 and the scanner 5 are electrically coupled to the processing module 4.

[0047] Furthermore, the displacement mechanism 3 is movable relative to the carrier body 2, and the processing module 4 is electrically coupled to the displacement mechanism 3 to drive the displacement mechanism 3 to sequentially move along a first cutting path and a second cutting path that are different from each other. The film cutting tool 1 is mounted on the displacement mechanism 3 via the mounting section 11, so that the film cutting tool 1 can move synchronously with the displacement mechanism 3.

[0048] 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.

[0049] It should be noted 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 which the film is to be applied. Accordingly, the processing module 4 can cause the film cutting device 100 to perform the corresponding cutting operation based on the mobile phone model input by the user, but the present invention is not limited to this. For example, in other embodiments not shown in the present invention, the processing module 4 can also receive signals from an external device (such as a computer or the user's mobile phone) through other means to obtain the model of the mobile phone to which the film is to be applied.

[0050] When the size film 200 is placed on the film cutting device 100 for the cutting operation, the size film 200 is fixed to the carrier body 2, and the displacement mechanism 3 is driven by the processing module 4, so that the main edge 13a of the film cutting tool 1 is first cut along the first cutting path relative to the positioning 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.

[0051] As described above, since the film cutting device 100 cuts into the size film 200 from the positioning layer 202 rather than from the bonding surface 2032 of the use layer 203, it can effectively reduce damage to the adhesive layer of the bonding surface 2032 and avoid burrs on the use layer 203.

[0052] It should be noted that the displacement mechanism 3 can drive the film cutting tool 1 to move relative to the sizing film 200 along mutually perpendicular X-axis, Y-axis, and Z-axis directions, and the object being moved (e.g., the film cutting tool 1 or the sizing film 200) can be adjusted 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 and the Z-axis, while the sizing film 200 is driven by the displacement mechanism 3 to move along the Y-axis, so that the film cutting tool 1 can move relative to the sizing film 200 along the first cutting path and the second cutting path in sequence.

[0053] Furthermore, after the sizing film 200 is cut to form the screen protector 200a, the positioning layer 202 has a screen area 2023 and a plurality of positioning areas 2024 separated from the screen area 2023. Furthermore, the sizing film 200 preferably includes a plurality of adhesive tapes 204 for respectively adhering the plurality of positioning areas 2024 to the screen area 2023. This facilitates the screen protector 200a to be fixedly mounted on a laminating machine (not shown) via the plurality of positioning areas 2024, thereby allowing the laminating machine to affix the laminating surface 2032 of the service layer 203 of the screen protector 200a to the screen of the mobile phone.

[0056] Furthermore, the film cutting tool disclosed in the embodiment of the present invention can also be more conducive to cutting the size film with a hardness of at least 5H and effectively avoid the generation of burrs on the size film on the bonding surface by having 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 match each other.
