Description

Technical Field

[0001] This invention relates to the field of film application equipment technology, specifically to a film applicator and its application method. Background Technology

[0002] With the advent of the Internet age, electronic devices have become increasingly indispensable tools in our lives. However, the screens of electronic devices are sometimes too fragile and are often scratched or even broken by accident, which affects the display effect and aesthetics of electronic devices. Replacing the screen requires a lot of money and time. Therefore, people usually put a protective film on the screen of electronic devices to protect the screen of tablets or mobile phones.

[0003] In real life, when applying screen protectors to mobile phones or mobile devices, screen protector application tools are usually used to assist in the application. Originally, a cleanroom and screen protector kit were used together for the application. However, in actual use, when the cleanroom is turned upside down to cover the mobile device, there is a problem that the cleanroom may fall off accidentally, and the screen protector kit may fall out of the cleanroom.

[0004] To solve this problem, manufacturers will attach a double-sided tape to the end between the cleanroom and the positioning film, and also attach a double-sided tape between the release film and the positioning film. The adhesive force of the double-sided tape is used to prevent the screen protector kit from coming loose from the cleanroom when the cleanroom falls to the ground.

[0005] However, in actual use, our company discovered that there is still room for optimization in the structure and components of this existing product in order to reduce production costs.

[0006] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to improve upon existing products by designing a film applicator that reduces the amount of double-sided adhesive used, thereby reducing production costs, and to provide a film application method using the film applicator.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a screen protector, comprising a cleanroom housing for connecting a screen protector to a mobile terminal, wherein the screen protector has a positioning film, a protective film, a release film, and a pull strip that are sequentially attached; a double-sided adhesive attachment is attached to one side between the positioning film and the release film; the positioning film has a through hole on the side near the double-sided adhesive attachment, such that the double-sided adhesive attachment between the positioning film and the release film is located directly above the through hole; in the working state: the release film and the double-sided adhesive attachment are depressed and deformed under pressure and pass through the through hole, and the bottom surface of the double-sided adhesive attachment adheres to the surface of the cleanroom housing.

[0009] Preferably, the double-sided adhesive accessory is double-sided tape;

[0010] Double-sided tape is used to achieve the goal of making both sides of double-sided adhesive attachments have adhesive ability.

[0011] Preferably, the double-sided adhesive attachment is generally rectangular, and the through hole is a rectangle that matches the shape of the double-sided adhesive attachment;

[0012] The rectangular double-sided adhesive attachment forms a straight line and adheres to the cleanroom shell surface after contacting it through the through-hole, thus improving the adhesion.

[0013] Preferably, the overall size of the double-sided adhesive attachment is 1.1-1.5 times the overall size of the through hole, so that the outer ring of the double-sided adhesive attachment adheres to the top surface of the positioning film, while the middle part does not contact the positioning film.

[0014] Preferably, one end of the positioning film has a foolproof groove, and the top surface of the dust-free chamber shell has a foolproof protrusion that matches the shape of the foolproof groove.

[0015] The cooperation between the anti-mistake protrusion and the anti-mistake groove allows the positioning film, protective film, release film and pull strip to be centered on the side closest to the anti-mistake protrusion.

[0016] Preferably, the cleanroom shell includes a base plate, two symmetrically distributed limiting ribs fixedly connected to the top surface of the base plate, and a pull-out groove opened at the end of the limiting ribs away from the anti-foolproof protrusion, wherein the pull bar passes through the pull-out groove and is slidably connected to the pull-out groove.

[0017] Preferably, a double-sided adhesive sheet is fixedly installed on the top surface of the base plate away from the double-sided adhesive attachment;

[0018] Double-sided adhesive sheets, used in conjunction with double-sided adhesive accessories, are used to prevent the cleanroom shell from accidentally falling off, causing the positioning film, protective film, release film, and pull strip to detach from the cleanroom shell.

[0019] Preferably, the positioning film has a pair of middle ears fixedly connected to both sides of the end away from the double-sided adhesive attachment, and the middle ears are in contact with the side wall of the limiting rib plate.

[0020] It plays a centralizing role in the middle ear, moving it away from the positioning membrane and away from the side of the anti-misalignment protrusion.

[0021] Secondly, the present invention also provides a film application method for the aforementioned film applicator, the film application method comprising the following steps:

[0022] S1. Place the assembled screen film inside the cleanroom shell, so that the positioning film is attached to the top surface of the inner cavity of the cleanroom shell. Press the pull strip to make the release film and double-sided adhesive deform downward under pressure and pass through the through hole until the bottom surface of the double-sided adhesive adheres to the surface of the cleanroom shell.

[0023] S2. Move the cleanroom casing to directly above the mobile terminal, so that the screen of the mobile terminal is facing the protective film, and gradually move the cleanroom casing downward to cover and wrap the mobile terminal, so that the screen of the mobile terminal is in contact with the surface of the pull strip.

[0024] S3. Pull the pull strip outward along the length direction, wherein when the pull strip causes the release film to separate from the protective film, it no longer adheres to the surface of the cleanroom shell, and the release film contacts the screen of the mobile terminal to absorb dust.

[0025] S4. After the dust removal release film is completely removed, draw a straight line along the length of the positioning film in the middle, so that the positioning film and the protective film gradually and automatically adhere to the screen of the mobile terminal from the middle.

[0026] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0027] 1. This product eliminates the double-sided adhesive attachment originally located between the cleanroom shell and the positioning film. Instead, it creates through holes in the positioning film, allowing the double-sided adhesive attachment, originally located between the positioning film and the release film, to pass through and adhere to the surface of the cleanroom shell. This not only achieves the effect of the original product but also reduces the use of one double-sided adhesive attachment, thus reducing production costs.

[0028] 2. This product improves the alignment of the positioning film, protective film, release film, and pull strip within the cleanroom shell by fixing centering ears on both sides of the positioning film away from the anti-foolproof protrusion, in conjunction with the anti-foolproof protrusion and anti-through groove, thereby improving the film application quality.

[0029] 3. By designing the dimensions between the through hole and the double-sided adhesive attachment, the outer ring of the double-sided adhesive attachment can adhere the positioning film and release film as in the prior art, while the middle part can be recessed downwards to contact the surface of the cleanroom shell.

[0037] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0039] Example 1:

[0040] like Figure 1-4 As shown, the system includes a base plate 101, two symmetrically distributed limiting ribs 102 fixedly connected to the top surface of the base plate 101, and a pull-out groove 103 opened at the end of the limiting ribs 102 away from the anti-mistake protrusion 9. The anti-mistake protrusion 9 is fixedly connected to the top surface of the base plate 101 away from the pull-out groove 103, and a double-sided adhesive sheet 10 is fixedly connected to the top surface of the base plate 101 near the pull-out groove 103. A positioning film 2, a protective film 3, a release film 4, and a pull strip 5 are sequentially attached and placed in the two limiting ribs 102 from bottom to top, and the pull strip 5 passes through the pull-out groove 103. The positioning film 2 has an anti-mistake through groove 8 that matches the anti-mistake protrusion 9. A double-sided adhesive attachment 6 is fixedly installed between the positioning film 2 and the release film 4, and a through hole 7 located directly below the double-sided adhesive attachment 6 is opened in the positioning film 2. A center ear 11 is also fixedly connected to both sides of the positioning film 2 away from the anti-mistake protrusion 9.

[0041] Before applying the screen protector to the mobile terminal, the user first places the positioning film 2, protective film 3, release film 4 and pull strip 5 stacked in sequence between the two limiting rib plates 102, so that the anti-mistake protrusion 9 is inserted into the anti-mistake through groove 8, and pushes the pull strip 5 into the pull groove 103. At this time, the centering ears 11 on both sides of the positioning film 2 will contact the surface of the limiting rib plate 102. With the anti-mistake protrusion 9 and the anti-mistake through groove 8, the positioning film 2, protective film 3, release film 4 and pull strip 5 are aligned. Then, press the pull strip 5 on the top of the double-sided adhesive attachment 6 to cause the release film 4 and the double-sided adhesive attachment 6 to be concave and deformed downwards, so that the side of the double-sided adhesive attachment 6 away from the release film 4 passes through the through hole 7 and adheres to the surface of the base plate 101. At the same time, the double-sided adhesive sheet 10 adheres to the bottom surface of the protective film 3.

[0042] Next, place the mobile terminal screen-down on the surface of the pull strip 5 and press it down to allow the mobile terminal to enter between the two limiting ribs 102. Then proceed with the existing screen protector application process.

[0043] Example 2:

[0044] This embodiment proposes a film application method for the film applicator as described in Embodiment 1. The film application method includes the following steps:

[0045] S1. Place the assembled screen protector inside the cleanroom housing 1, align the anti-mistakes groove 8 on the positioning film 2 with the anti-mistakes protrusion 9 on the cleanroom housing 1, and make the centering ears 11 on both sides of the positioning film 2 fit against the side wall of the limiting rib plate 102 to center the positioning film 2. Then, make the positioning film 2 fit against the top surface of the inner cavity of the cleanroom housing 1 and position it on the cleanroom housing 1. Then, press the pull strip 5 to make the release film 4 and the double-sided adhesive attachment 6 deform downward under the pressure, so that the two sides of the outer ring of the double-sided adhesive attachment 6 bond the release film 4 and the positioning film 2 together, and let the middle part of the double-sided adhesive attachment 6 pass through the through hole 7 until the bottom surface of the double-sided adhesive attachment 6 is bonded to the surface of the cleanroom housing 1.

[0046] S2. Move the cleanroom casing 1 directly above the mobile terminal, with the mobile terminal screen facing upwards, so that the screen of the mobile terminal is directly facing the protective film 3, and gradually move the cleanroom casing 1 downwards until it covers and wraps the mobile terminal, so that the screen of the mobile terminal is in contact with the surface of the pull strip 5.

[0047] S3. Pull the pull strip 5 outward along the length direction. When the pull strip 5 causes the release film 4 to separate from the protective film 3, it no longer adheres to the surface of the cleanroom shell 1. The release film 4 comes into contact with the screen of the mobile terminal to absorb dust.

[0048] S4. After the dust removal release film 4 is completely removed, draw a straight line along the length of the positioning film 2 in the middle, so that the positioning film 2 causes the protective film 3 to sink downwards, and the protective film 3 gradually and automatically adheres to the screen of the mobile terminal from the middle.

[0049] In summary, after the screen protector is installed on the cleanroom housing 1, the double-sided adhesive attachment 6 adheres to the surface of the cleanroom housing 1. If the cleanroom housing 1 is accidentally dropped, the double-sided adhesive attachment 6 will prevent the screen protector from separating from the cleanroom housing 1.

[0050] In the actual installation process, you only need to install the screen protector, then cover it up, pull it, and then slide it to complete the quick screen protector application process.
