Description

Technical Field

[0001] The present application relates to the technical field of screen film application for electronic products, and in particular to an automatic film application device and a film application method for a UV-curable protective film for a curved screen of a mobile phone. Background Art

[0002] With the popularity and widespread application of smart phones, as well as the development of curved screen and flexible screen terminal devices, in order to avoid high replacement costs due to screen breakage, protective films are needed to protect the screen; the hard PET protective films commonly seen on the market are prone to warping and white edges when attached to the edges of curved screens, which affects the use effect, has a short service life, and provides a very poor user experience; in response to the needs of this market, UV light-cured screen protective films came into being. UV light-cured screen protective films have excellent surface hardness and smoothness, as well as good impact resistance, which can effectively prevent the screen from breaking; at the same time, UV light-cured screen protective films can effectively fit the curved surface without bubbling or warping, and long-term use will not affect the appearance. However, at the same time, UV light-cured screen protective films require high operating skills and proficiency of the film-applying personnel, and require auxiliary tools to improve the success rate and fit of the film-applying.

[0003] In life, more and more people buy mobile phone films online, but most people have no experience in film application. In the specific process of applying film to mobile phones, there are actually many problems with film application, such as broken wire traces, inaccurate positioning, laminating bubbles, poor control of extrusion force leading to material deformation, etc. In the conflict between market demand and technical defects, it is necessary to continuously innovate and improve the existing auxiliary film application devices and the ease of operation, so as to simplify the operation of mobile phone film application for ordinary consumers, make the film application more beautiful, and achieve the goal that everyone can apply film and everyone can apply film well.

[0004] There are various problems in the many devices and technologies related to mobile phone curved screen film that are currently disclosed, such as:

[0005] Patent CN102542914A provides a display method and device for screen films of electronic products, which involves pasting the screen film to be displayed on a flat substrate of highly light-transmitting transparent material, and then placing the other side of the substrate that is not pasted with the film close to the screen of the product. This technology is only used for performance testing of screen films and cannot be applied to films for mobile phone screens currently used by consumers.

[0006] Patent CN103848000A provides a display method and device for screen film pasting. This method ensures the accuracy of film pasting by assisting the soft plastic sheet to adhere and position the pre-film, facilitates the user's film pasting operation, reduces the possibility of the film being pasted crookedly during the film pasting process, and reduces the difficulty of operation and improves the success rate of film pasting. Although the technology is simple and easy to operate, ordinary people can apply and implement it, but the four-sided magnetic strip fixing method is still prone to displacement and deviation during operation, resulting in crooked pasting.

[0007] Patent CN108481731A discloses a screen film sticking device for a touch-screen mobile phone. By setting up a mounting table, a film placing component and a film sticking component, the mobile phone film sticking operation can be automatically performed. Compared with the current film sticking method, it can effectively improve work efficiency and improve the appearance of the film-sticking screen. This technical device is complex and costly, and is only suitable for mobile phone manufacturers or large sales outlets, and is not widely used.

[0008] Patent CN110154374A provides a rolling device for curved screen film, which includes a roller, a reciprocating drive mechanism, a pressure sensor, a correction mechanism and a controller. The pressure sensor is used to detect the pressure of the roller on the film. The device makes the pressure applied by the roller at each height of the curved screen constant within a certain range, achieving uniform pressure to remove bubbles, thereby reducing time consumption. Although the appearance of the bonding is improved, the equipment is complex and the product cost is too high. It is not suitable for ordinary mobile phone stores, let alone normal mobile phone users.

[0009] Therefore, it is necessary to provide a mobile phone curved screen protective film film pasting device and film pasting method to solve the above technical problems. Utility Model Content

The main structure includes a base 1 and a film pasting structure, the outer part of the base 1 is hinged with an upper cover 2, the bottom of the base 1 is provided with a snap-in groove for snapping the upper cover 2, the upper surface of the upper cover 2 is provided with a transparent silicone sleeve, and the inner top of the upper cover 2 is provided with an elastic film body 5;

[0048] The upper surface of the base 1 is provided with a mobile phone body 6;

[0049] The first positioning component is arranged inside the base 1 and is used to be inserted into the charging hole of the mobile phone body 6, so as to achieve the purpose of fixing the mobile phone body 6;

[0050] The second positioning component is arranged on the upper surface of the base 1 and is used to cooperate with the first positioning component to fix the mobile phone body 6 more stably.

[0051] It should be noted that, through the arrangement of the first positioning component and the second positioning component, it is convenient for the user to fix the mobile phone body 6 inside the base 1. After the mobile phone body 6 is fixed, the film structure is placed inside the base 1. When the film structure fits the screen of the mobile phone body 6, the upper cover 2 is closed. At this time, the mobile phone body 6 can be filmed without the need for tedious steps such as inflation, and no external pressure is required, and the operation is convenient.

[0052] Furthermore, the film structure includes a protective film layer, a service film layer, a release film layer and a pull strip layer from top to bottom.

[0053] Specifically, when the mobile phone body 6 needs to be treated with a film, it is only necessary to align the corresponding hole positions of the film structure and place them on the positioning columns of the base 1, and extend the pull rod holes of the pull rod base 1 of the film structure, and then pull the pull rod to peel off the release film layer of the film structure, and use a scraper to scrape the flat part of the mobile phone body 6 from one end to the other at a uniform speed.

[0054] Further, such as Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the first positioning component includes a USB interface 10 arranged below the base 1.

At this time, the reset spring 9 is reset, driving the slider 7 to reset and move synchronously. When the slider 7 conflicts with the outside of the mobile phone body 6, the mobile phone body 6 can be further fixed to prevent the mobile phone body 6 from shaking, thereby achieving the purpose of positioning the mobile phone body 6.

[0058] Further, such as Figure 2As shown, a UV curing lamp board 3 is provided at the inner top of the upper cover 2 .

[0059] It should be noted that, through the provision of the UV curing light board 3 and the elastic film body 5, it is convenient for the user to apply the film to the mobile phone body 6, and at the same time, it can effectively improve the fit between the film structure and the curved mobile phone body 6, and can also effectively improve the efficiency and effect of the film application of the mobile phone body 6.

[0060] Further, such as Figure 2 As shown, the elastic membrane 5 is a ring-shaped film with certain elasticity, such as rubber, polyurethane, PET, PI, etc.

[0061] Specifically, since the elastic film 5 is an annular film with a certain elasticity, the elasticity of the elastic film 5 itself can be combined with the self-stretching of the upper cover 2 to perfectly fit the film structure to the screen of the curved mobile phone body 6. At the same time, there is no need for tedious steps such as inflation, and no external pressure is required, which improves the efficiency and effect of the mobile phone body 6 when applying the film.

[0062] Further, such as Figure 2 As shown, the UV curing lamp board 3 includes an aluminum substrate and 20 365nm UV lamp beads 4.

[0063] It should be noted that when the mobile phone body 6 needs to be treated with a film, you only need to insert the USB Type-C charging cable into the USB port 10 corresponding to the UV curing light board 3 and turn on the power. At this time, the UV lamp beads 4 will light up. After 3 minutes, the UV lamp beads 4 will go out. At this time, open the upper cover 2, take the mobile phone body 6 out of the base 1, and then tear off the protective film layer of the film structure. The mobile phone body 6 can be treated with a film, which saves time and effort.

[0064] The utility model also includes a method for applying a mobile phone screen protective film, which comprises the following steps:

[0065] S1: Clean the surface of the mobile phone body 6;

[0066] S2: insert the charging hole at the rear of the mobile phone body 6 into the first positioning assembly, and place the mobile phone body 6 in the base 1 of the film sticking device so that the mobile phone body 6 is snapped onto the second positioning assembly, with the screen of the mobile phone body 6 facing upwards;
