Technical Field

[0001] The utility model relates to the technical field of screen protection, in particular to a protective film component applied to a mobile terminal film laminating machine and the mobile terminal film laminating machine. Background Art

[0002] Screen protectors for electronic devices are used to both decorate and protect the exterior of mobile phone screens. Typically only 0.1mm thick, these films completely cover the screen, preventing damage and scratches. They also provide increased shock absorption without affecting the display quality. Current protective film categories include privacy films, mirror films, AR films, frosted films, HD films, scratch-resistant films, 3D films, scratch-resistant mobile phone body films, diamond films, and tempered films.

[0003] Traditional protective film application methods rely on manual application, resulting in high costs, low efficiency, and variable results. To improve application efficiency and reduce labor costs, mobile terminal film application machines have been developed. These machines can automatically apply the film without human supervision. Before use, protective films are covered on both sides with release film or other insulating structures to isolate the colloid from the film. However, current insulating structures on protective films typically only have a small protrusion on one side to facilitate manual tearing, making them difficult for mobile terminal film application machines to identify and remove the film. Utility Model Content

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art and to provide a protective film assembly for a mobile terminal film laminating machine and a mobile terminal film laminating machine.

[0006] A first dividing line is provided at the front end of the substrate, and the substrate is divided into a film tearing area and a supporting area along the first dividing line. The supporting area is used to receive a supporting force from the back side to the front side of the substrate when tearing the film, and the film tearing area is used to receive a separating force in the opposite direction of the supporting force when tearing the film. The protective film body is provided on the front side of the supporting area, and one side of the protective film body is flush with the first dividing line.

[0007] In some optional embodiments, a second dividing line is further provided at the rear end of the substrate, and the substrate is divided into a tearing area, a carrying area and a safety area along the first dividing line and the second dividing line in sequence. The protective film body is provided on the front of the carrying area, and the first edge of the protective film body is flush with the first dividing line, and the second edge of the protective film body opposite to the first edge does not exceed the second dividing line.

[0008] In some optional embodiments, a center line is provided in the middle of the bearing area, and the center axis of the protective film body corresponds to the position of the center line.

[0009] In some optional embodiments, the center line is connected to the center of the first dividing line and is perpendicular to the first dividing line.

[0010] In some optional embodiments, the substrate includes a hard board layer and a printing layer that are stacked together, the first dividing line is arranged on the printing layer, and the protective film body is arranged on the hard board layer.

[0011] In some optional embodiments, the hard board layer is a transparent hard board layer, the first dividing line is located on a side of the printing layer close to the hard board layer, and the protective film body is arranged on a side of the hard board layer away from the printing layer.

[0030] See also Figure 1 An embodiment of the present invention provides a protective film assembly for a mobile terminal film laminating machine, including: a substrate 10 and a protective film body 20.

[0031] See also Figure 2 The front end of the substrate 10 is provided with a first dividing line 11. The substrate 10 is divided into a film tearing area 13 and a bearing area 14 along the first dividing line 11. The bearing area 14 is used to receive a supporting force from the back to the front of the substrate 10 when tearing the film. The film tearing area 13 is used to receive a separation force in the opposite direction of the supporting force when tearing the film. The protective film body 20 is provided on the front of the bearing area 14, and one side of the protective film body 20 is flush with the first dividing line. When the protective film body 20 is assembled to the substrate 10, the side of the protective film body 20 is aligned with the first dividing line 11, so that the side of the protective film body 20 and the first dividing line 11 are as flush as possible. This is conducive to the alignment of the protective film body 20, so that the position of the protective film body 20 relative to the substrate 10 is unified, which is convenient for mass production. Moreover, after the protective film assembly used in the mobile terminal film laminating machine is placed in the film bin of the mobile terminal film laminating machine, it is conducive to the clamping mechanism clamping in a unified position.

[0032] See also Figure 3The support of the support table 31 prevents the protective film body 20 from being pulled down by the adhesive force between the substrate 10 and the protective film body 20, thereby preventing the protective film body 20 from being separated from the adsorption of the vacuum clamping mechanism 30. After the lower pressure rod 32 is pressed down, the horizontal height of the lower pressure rod 32 is lower than the horizontal height of the protective film body 20, and is located between the protective film body 20 and the substrate 10. Then, the vacuum clamping mechanism 30 moves the protective film assembly used in the mobile terminal film laminating machine along the top of the support platform 31 toward the lower pressure rod 32. Since the lower pressure rod 32 separates the protective film body 20 and the substrate 10, the protective film body 20 and the substrate 10 are gradually peeled off when the protective film assembly used in the mobile terminal film laminating machine moves, thereby realizing the film tearing operation. The above-mentioned special film tearing operation is conducive to preventing the protective film body 20 from detaching from the vacuum clamping mechanism 30, which is conducive to reducing the adsorption force requirements of the vacuum clamping mechanism 30 on the protective film body 20 and improving the accuracy of film tearing.

[0033] In some optional embodiments, a second dividing line is further provided at the rear end of the substrate 10. The substrate 10 is divided into a tearing area 13, a carrying area 14, and a safety area 15 along the first dividing line 11 and the second dividing line 12. The protective film body 20 is provided on the front of the carrying area 14. The first side of the protective film body 20 is flush with the first dividing line, and the second side of the protective film body 20 opposite to the first side does not exceed the second dividing line 12. A certain space can be reserved for the safety area 15 to prevent the protective film body 20 from being too large and exceeding the carrying area 14. Even if the protective film body 20 just covers the carrying area 14, a certain margin is left for the safety area 15 so that the safety area 15 protrudes from the side of the protective film body 20, which is beneficial to provide certain protection for the side of the protective film body 20 and prevent the side of the protective film body 20 from being bumped or scratched during packaging and transportation. Of course, the safety area 15 is not a must. In other embodiments, the safety area 15 and the second dividing line 12 may not be provided. The tearing area 13 also protrudes from the side of the protective film body 20 , which is also beneficial for providing certain protection for the side of the protective film body 20 .

[0034] In some optional embodiments, a center line 16 is provided in the middle position of the supporting area 14, and the central axis of the protective film body 20 corresponds to the position of the center line 16. The center line 16 facilitates the alignment of the protective film body 20. The first dividing line 11 and the center line 16 cooperate to align the protective film body 20, so that when the protective film assembly is assembled for use in a mobile terminal film laminating machine, the position of the protective film body 20 relative to the substrate 10 is more precise.

[0035] In some optional embodiments, the center line 16 is connected to the center of the first dividing line 11 and is perpendicular to the first dividing line. The center line 16 and the first dividing line 11 adopt a T-shape that is staggered horizontally and vertically, which is more conducive to the alignment of the position of the protective film body 20 and improves the assembly accuracy.

[0036] See also Figure 4 Since the protective film body 20 usually adopts a film with high hardness and not easy to bend, such as a tempered film, in some optional embodiments, the substrate 10 includes a stacked hard board layer 17 and a printed layer 18, the first dividing line 11 is arranged on the printed layer 18, and the protective film body 20 is arranged on the hard board layer 17. The hard board layer 17 is made of a hard material, which is conducive to providing sufficient support for the overall structure of the substrate 10, so that the overall hardness of the substrate 10 is sufficient to support the protective film body 20, and avoid bending and deformation of the protective film body 20 during packaging and transportation, thereby providing protection for the protective film body 20. Moreover, in the above-mentioned special film tearing operation, since the lower pressure rod 32 is required to bend the substrate 10 so that part of the substrate 10 is peeled off from the protective film body 20, there are certain requirements for the hardness of the substrate 10. If the hardness of the substrate 10 is not enough, it will cause the substrate 10 to have insufficient stress after being bent by the lower pressure rod 32, resulting in the substrate 10 being unable to overcome the adhesive force between it and the protective film body 20 and the substrate 10 being unable to be peeled off from the protective film body 20. The printing layer 18 facilitates clear printing of the first cutting line, thereby facilitating identification of the first cutting line.

[0037] The hard board layer 17 can be made of hard materials such as plastic, and the printing layer 18 can be made of materials that are easy to print, such as paper, but is not limited to this example.

[0038] In some optional embodiments, the hardboard layer 17 is transparent, the first dividing line 11 is located on the side of the printed layer 18 closest to the hardboard layer 17, and the protective film body 20 is located on the side of the hardboard layer 17 away from the printed layer 18. Because the first dividing line is protected by the hardboard layer 17, it is less likely to become unclear due to wear and tear during packaging and transportation, thereby improving the service life. In this embodiment, the center line 16 and the second dividing line 12 are also located on the side of the printed layer 18 closest to the hardboard layer 17.

[0039] Because screen sizes vary across electronic devices, the size of the protective film body 20 also varies. In some optional embodiments, the area of ​​the supporting area 14 is larger than the area of ​​the protective film body 20, as projected from the protective film body 20 onto the supporting area 14. The sufficient size of the supporting area 14 facilitates mass production of identical substrates 10 for assembly with different types of protective film bodies 20. Furthermore, the sufficient size of the supporting area 14 allows it to protrude from the side edges of the protective film body 20, leaving a blank space. This helps reduce side wear on the protective film body 20.

[0040] In some optional embodiments, the carrying area 14 protrudes from both sides of the protective film body 20 in a direction away from the tearing area 13, which helps reduce side wear of the protective film body 20. In this embodiment, because the carrying area 14 protrudes from both sides of the protective film body 20 in a direction away from the tearing area 13, and the tearing area 13 and the safety area 15 also protrude from the sides of the protective film body 20, the protective film body 20 has a protruding substrate 10 structure on all four sides, which helps to provide maximum protection for the sides of the protective film body 20.

[0041] See also Figure 5 and Figure 6 In some optional embodiments, the width of the tearing area 13 gradually decreases as it moves away from the supporting area 14. This reduced tearing area 13 reduces the contact area between the lower pressing rod 32 and the tearing area 13 when the lower pressing rod 32 presses against the tearing area 13, thereby increasing the concentration of pressure from the lower pressing rod 32 on the tearing area 13, facilitating the pressing of the tearing area 13 and making the substrate 10 easier to bend. The tearing area 13 can be designed in a suitable shape, such as a triangle, a semicircle, or a trapezoid.

[0042] The protective film assembly for a mobile terminal film laminating machine described above can be used on a film laminating machine, which includes: a housing, a film bin, and the protective film assembly for a mobile terminal film laminating machine described above. The film bin is disposed within the housing, and the protective film assembly for the mobile terminal film laminating machine is accommodated within the film bin. The housing of the film laminating machine is generally further provided with a vacuum clamping mechanism 30 and a film tearing mechanism. The vacuum clamping mechanism 30 clamps and adsorbs the protective film assembly for the mobile terminal film laminating machine in the film bin. The vacuum clamping mechanism 30 transports the protective film assembly for the mobile terminal film laminating machine to the film tearing mechanism to peel off the substrate 10. The vacuum clamping mechanism 30 then moves the protective film body 20 to the screen of the electronic device.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
