Description

Technical Field

[0001] The utility model relates to the technical field of electronic device accessories, in particular to a film applicator. Background Art

[0002] At present, electronic devices have become essential communication tools in people's lives. However, due to frequent use of electronic devices, the screens of electronic devices are prone to getting dirty or even scratched. Generally, the screens of electronic devices are protected by tempered glass films. The tempered glass film has a self-adhesive property, which is mainly reflected in that when a part of the tempered glass film is attached to the screen of the electronic device, even without applying external force, relying on its own gravity, the attached area will continuously expand outward until full attachment is achieved.

[0003] Some film applicators that are convenient for film application have appeared on the market. They are provided with structures that can fix and position the tempered film assembly. When applying a film to an electronic device, the electronic device is placed in the film applicator, and the tempered film assembly is fixed to the positioning structure on the film applicator, and then it can be covered on the screen of the electronic device and aligned with the electronic device, so that the tempered film can be installed on the screen of the electronic device. Although the accuracy of film application can be improved, when installing the film application assembly, most are manually installed by operators onto the film applicator. During the manual operation process, it is not only cumbersome but also easy to cause the positioning film in the tempered film assembly to separate from the tempered film, thus losing the positioning function, making the tempered film unable to be aligned with the screen of the electronic device, resulting in film application failure.

The film pressing roller 42 is pivotally connected between the two mounting portions 43. A slider 44 that is slidably mounted on the slide rail 11 is provided outside the mounting portion 43. The film pressing roller 42 has a variable-diameter columnar structure with larger diameters at both ends and a smaller diameter in the middle. By setting the film pressing roller 42 to have a variable-diameter columnar structure, the film pressing roller 42 can be more closely attached to an electronic device with a curved screen edge.

[0070] Chute 14 is provided at positions on both sides of the positioning box body 1 close to the slide rail 11;

[0071] A stabilizing plate 45 that is slidably mounted in the chute 14 is further provided at the joint of the slider 44 and the mounting portion 43.

The positioning frame 3 is rotatably connected to the positioning box body 1 and freely rotates with the connection point with the positioning box body 1 as the rotation base point. The roller assembly 4 can slide on the slide rail 11.

[0120] The positioning box body 1 is further provided with a positioning block 15 for aligning and engaging with the positioning frame 3;

[0121] In this embodiment, during the film pasting process, by utilizing the alignment relationship between the positioning frame 3 and the placement groove 2, the film pasting assembly 7 can be conveniently and quickly aligned with the electronic device screen. Since the positioning frame 3 and the placement groove 2 are in a mutually aligned state under normal conditions, by flipping open the positioning frame 3 to expose the placement groove 2, the electronic device can be placed into the placement groove 2. Further, by rotating the positioning frame 3 to cover the electronic device, when the positioning frame 3 covers the electronic device, the positioning frame 3 and the positioning block 15 are engaged with each other, and the film pasting assembly 7 mounted thereon is covered on the electronic device screen. Then, by sliding the roller assembly 4, the film pasting work can be completed. This process has simple steps and high film pasting accuracy.

[0122] Further, a disassembly opening 8 is provided on the slide rail 11, and the width of the disassembly opening 8 is the same as the width of the slider 44.

[0123] Further, on both outer walls of the connection between the pressing cover 5 and the positioning box body 1, first mounting blocks 51 are provided, and the first mounting blocks 51 are snap-fitted into the first mounting grooves 12 provided on the positioning box body 1.

[0124] In this embodiment, both the pressing cover 5 and the positioning frame 3 are movable components rotatably mounted on the positioning box body 1, and together with the positioning box body 1, they form a complete tool for pasting a film on an electronic device. Among them, the positioning box body 1 serves as a container for the electronic device, and the positioning frame 3 serves as a component for aligning the film pasting assembly 7 with the electronic device screen, which can ensure accurate film pasting on the electronic device.

[0125] Further, a roller assembly 4 is also slidably provided on the positioning box body 1.

[0126] Further, the roller assembly 4 includes a sliding frame 41 and a film pressing roller 42. Both ends of the sliding frame 41 extend downward and are provided with mounting portions 43 slidably mounted on the slide rail 11. The film pressing roller 42 is pivotally connected between the two mounting portions 43. A slider 44 slidably mounted on the slide rail 11 is provided outside the mounting portion 43. The film pressing roller 42 has a variable-diameter columnar structure with larger diameters at both ends and a smaller diameter in the middle; setting the film pressing roller 42 as a variable-diameter columnar structure can make the film pressing roller 42 fit more closely with an electronic device with a curved screen edge.

[0127] In this embodiment, the sliding frame 41 is a plate-like structure, and a strip-shaped groove for avoiding the mounting portions 43 provided on both sides of the sliding frame 41 is reserved on the pressing cover 5. The sliding frame 41 is located on the pressing cover 5. When the sliding frame 41 slides, the mounting portions 43 move in the strip-shaped groove, and the sliding frame 41 can be pulled to paste the film while the pressing cover 5 is tightly covered on the positioning box body 1.

[0128] On both sides of the positioning box body 1 near the slide rail 11, there are sliding grooves 14 provided.

[0129] At the joint of the slider 44 and the mounting part 43, there is also a stabilizing plate 45 slidably mounted in the sliding groove 14. The slider 44 and the stabilizing plate 45 are integrally connected to the mounting part 43. By providing the stabilizing plate 45, it can ensure that the roller assembly 4 slides in a straight line during the film application process. Cooperating with the slider 44, it can prevent the roller assembly 4 from detaching from the positioning box body 1 during sliding, making the film application more stable.

[0130] Furthermore, in the positioning box body 1, there is an elastic cushion block 6 that enables the roller assembly 4 to transition from the positioning box body 1 to the electronic device screen in the placement groove 2. The elastic cushion block 6 is arranged to be lifted and lowered.

[0131] Furthermore, the positioning box body 1 is provided with a receiving groove 17 communicating with the placement groove 2. The elastic cushion block 6 is an extension plate extending from one side wall of the receiving groove 17 away from the placement groove 2 towards the other side wall close to the placement groove 2.

[0132] On the surface of the elastic cushion block 6 that fits with the edge of the electronic device, there are convex strips 61 provided. Since during the film application process, one side edge surface of the electronic device will fit with one surface of the elastic cushion block 6, and the elastic cushion block 6 will move up and down during the film application process, it is easy to cause large - area friction on the edge surface of the electronic device. By providing the convex strips 61, the friction area between the elastic cushion block 6 and the edge surface of the electronic device is greatly reduced, which can avoid large - area friction between the electronic device and the elastic cushion block 6 during film application and at the same time play a role in further fixing the electronic device.

[0133] On the positioning box body 1, there is an elastic cushion block 6. On the elastic cushion block 6, there are convex blocks 62. On the convex blocks 62, there are several first positioning members corresponding to the first positioning holes 711. On the top surface of the end of the positioning box body 1 far from the elastic cushion block 6, there are several third positioning members 63 corresponding to the second positioning holes 712.

During the attachment process, in cooperation with the roller assembly 4, the roller assembly 4 presses the film pasting assembly 7, so that the film pasting assembly 7 is attached to the screen of the electronic device. Since the elastic cushion blocks 6 will generate an upward restoring force on the film pasting assembly 7, when the roller assembly 4 slides from the elastic cushion blocks 6 to the other end of the positioning box body 1, the protective film 73 will be first attached to the side of the electronic device screen close to the elastic cushion blocks 6. When the side of the electronic device screen close to the elastic cushion blocks 6 reaches a closely attached state, the roller assembly 4 is further used to slide the protective film 73 from one end of the electronic device to the other end.

[0136] Further, an elastic part 32 corresponding to the position of the elastic cushion block 6 is arranged on the positioning frame 3;

The area of the part pasted on the bottom of the positioning box body 1 is the same as the area of the part covering the top of the positioning box body 1. The flip cover 9 can serve as a protective casing for the positioning box body 1 and jointly form the outer packaging structure of the product with the packaging box 10.

[0144] Furthermore, a joint opening 37 corresponding to the positioning block 15 is formed at one end of the positioning plate 35 away from the elastic part 32. By setting the joint opening 37 to be snap-connected with the positioning block 15, the stable installation of the positioning frame 3 on the positioning box body 1 can be ensured. The opening area of the positioning opening 36 is smaller than that of the placement groove 2.

[0145] Furthermore, the film applicator further includes a film application assembly 7. The film application assembly 7 includes a positioning film 71, a pull film 72, and a protective film 73.
