Description

Technical Field

[0001] This utility model relates to cover plate coating technology, and more particularly to a mobile phone cover plate coating structure. Background Technology

[0002] With the widespread use of smartphones, people have increasingly higher demands for them. They not only require smartphones to meet functional needs such as communication and entertainment, but also to meet personalized aesthetic requirements.

[0003] The phone cover is located on the outermost surface of a smartphone, serving not only to protect the internal components (such as the screen and battery) but also to meet personalized aesthetic needs through various cosmetic coatings. Since smartphones integrate cameras, the phone cover needs to have a pre-reserved area for the camera hole to capture images. Therefore, during the coating process, various cosmetic coatings must avoid this camera hole area on the phone cover.

[0004] In traditional coating processes, to avoid obstructing the camera hole area on the phone's cover during coating, a layer of double-sided adhesive is first applied to the camera hole area. After coating, the double-sided adhesive is peeled off the phone's cover to expose the camera hole. However, double-sided adhesive is quite sticky, and after peeling, it easily leaves residue on the camera hole area. This not only affects the camera's shooting performance but also makes it easy for fingerprints and dust to accumulate during use. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a mobile phone cover plate coating structure that can prevent residual adhesive from being left in the camera hole area.

[0006] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0007] A mobile phone cover plate coating structure, comprising:

[0008] The cover plate body has a camera hole area for mounting a camera;

[0009] A light-curable easy-tear adhesive layer is disposed on the front side of the cover plate body and covers the camera hole area;

[0010] An appearance coating layer is disposed on the front side of the cover plate body, and surrounds and covers the UV-curable easy-tear adhesive layer.

[0011] Furthermore, the photocurable easy-tear adhesive layer is a UV easy-tear adhesive layer.

[0012] Furthermore, the thickness of the photocurable easy-tear adhesive layer is 4-6 μm.

[0013] Furthermore, the thickness of the surface coating layer is 50-200 nm.

[0014] Furthermore, the mobile phone cover plate coating structure also includes an anti-reflective coating layer, which is disposed on the outer coating layer.

[0015] Furthermore, the thickness of the anti-reflective coating layer is 100-300 nm.

[0016] Furthermore, the mobile phone cover plate coating structure also includes an anti-fingerprint coating layer, which is disposed on the anti-reflective coating layer.

[0017] Furthermore, the thickness of the anti-fingerprint coating layer is 30-50nm.

[0018] Furthermore, the mobile phone cover plate coating structure also includes a screen printing ink layer, which is disposed on the back of the cover plate body and surrounds the periphery of the camera hole area.

[0019] Furthermore, the thickness of the screen printing ink layer is 10-14 μm.

[0020] This invention has the following beneficial effects: Before coating, the camera hole area is covered on the front side of the cover body with a light-curing adhesive. Then, the light-curing adhesive is irradiated with light of a specific wavelength to solidify and form a light-curing easy-tear adhesive layer, which shields the camera hole area. Next, the front side of the cover body is coated to form the appearance coating layer. Due to the shielding effect of the light-curing easy-tear adhesive layer, the appearance coating layer does not contact the camera hole area but surrounds and partially covers it. Finally, the light-curing easy-tear adhesive layer is peeled off (the portion of the appearance coating layer covering it is also peeled off), exposing the camera hole area of ​​the cover body, thus avoiding residual adhesive in the camera hole area.

[0027] Example 1

[0028] like Figure 1 As shown, a mobile phone cover plate coating structure includes:

[0029] The cover plate body 1 is provided with a camera hole area 10 for mounting a camera;

[0030] A light-curable easy-tear adhesive layer 2 is disposed on the front side of the cover plate body 1 and covers the camera hole area 10;

[0031] The appearance coating layer 3 is disposed on the front side of the cover plate body 1, and surrounds the periphery of the light-cured easy-tear adhesive layer 2 and covers the light-cured easy-tear adhesive layer 2.

[0032] The photocurable peelable adhesive layer 2, also called a photocurable peelable adhesive layer, is an adhesive layer sensitive to specific wavelengths of light. Its adhesiveness changes significantly under the illumination of specific wavelengths of light. Under the illumination of specific wavelengths of light, the photocurable peelable adhesive layer 2 changes from a liquid state to a solidified state to protect the camera hole area 10 from contamination and penetration by the coating material. The adhesiveness of the photocurable peelable adhesive layer 2 decreases significantly after solidification, thus achieving a state where it can be peeled off by hand. Due to the significant decrease in adhesiveness, the photocurable peelable adhesive layer 2 can avoid leaving adhesive residue in the camera hole area 10 when it is peeled off.

[0033] Before coating, the camera hole area 10 of the cover plate body 1 is first covered with light-curing adhesive on the front side of the cover plate body 1. Then, the light-curing adhesive is irradiated with light of a specific wavelength to solidify and form the light-curing easy-tear adhesive layer 2, which shields the camera hole area 10. Then, the front side of the cover plate body 1 is coated to form the appearance coating layer 3. At this time, due to the shielding effect of the light-curing easy-tear adhesive layer 2, the appearance coating layer 3 will not contact the camera hole area 10, but will surround the periphery of the light-curing easy-tear adhesive layer 2 and partially cover it. Finally, the light-curing easy-tear adhesive layer 2 is peeled off (the part of the appearance coating layer 3 covering the light-curing easy-tear adhesive layer 2 will also be peeled off), so as to expose the camera hole area 10 of the cover plate body 1, thereby avoiding leaving residual adhesive in the camera hole area 10.

[0034] In this embodiment, the photocurable easy-tear adhesive layer 2 is a UV easy-tear adhesive layer with a thickness of 4-6 μm. That is, the photocurable easy-tear adhesive layer 2 will solidify under UV light irradiation to protect the camera hole area 10 from contamination and penetration of the coating material.

[0035] The light-curing adhesive is formed on the front side of the cover plate body 1 by screen printing. During screen printing, the mesh distribution on the screen printing plate can be designed so that the adhesive only covers the camera hole area 10 and avoids other areas of the camera hole area 10.

[0036] The thickness of the appearance coating layer 3 is 50-200 nm. The specific thickness of the appearance coating layer 3 can be determined according to the color, texture or pattern to be displayed. If the appearance coating layer 3 is a solid color coating layer, such as a blue coating layer or a green coating layer, its thickness is relatively small, between 50-80 nm. If the appearance coating layer 3 is a gradient color coating layer or a coating layer with a specific texture / pattern, multiple coatings are required, and its thickness is relatively large, between 70-200 nm.

[0037] The appearance coating layer 3 is formed on the front side of the cover plate body 1 by magnetron sputtering, chemical sputtering or vapor deposition. These methods cannot control the coating material to selectively form a film only on a local area of ​​the cover plate body 1. Instead, the film is formed on the entire area of ​​the cover plate body 1 indiscriminately. Therefore, the photocurable easy-tear adhesive layer 2 is needed to cover the camera hole area 10 to prevent the coating material from covering the camera hole area 10 and thus affecting the light transmittance of the camera hole area 10.

[0038] In this embodiment, the cover plate body 1 is preferably a glass cover plate with a thickness of 1-3mm; the number of camera hole areas 10 depends on the number of cameras on the mobile phone, and is generally 1-3.

[0039] like Figure 2 As shown, the mobile phone cover plate coating structure also includes an anti-reflective coating layer 4 and an anti-fingerprint coating layer 5. The anti-reflective coating layer 4 is disposed on the outer coating layer 3, and the anti-fingerprint coating layer 5 is disposed on the anti-reflective coating layer 4.

[0040] The anti-reflective coating layer 4 is used to reduce the surface reflectivity of the appearance coating layer 3, so as to prevent the appearance coating layer 3 from affecting its visual effect due to a large amount of ambient light reflection; the anti-fingerprint coating layer 5 is used to prevent fingerprints, dust and other contaminants from adhering to the surface of the anti-reflective coating layer 4, so as to facilitate later cleaning and maintenance.

[0041] The reflective coating layer and the anti-fingerprint coating layer 5 are also formed on the front side of the cover plate body 1 by means of magnetron sputtering, chemical sputtering or vapor deposition, etc. The peeling process of the photocurable easy-tear adhesive layer 2 is placed after the coating process of the reflective coating layer and the anti-fingerprint coating layer 5.

[0042] In this embodiment, the thickness of the anti-reflective coating layer 4 is 100-300nm, and the thickness of the anti-fingerprint coating layer 5 is 30-50nm.

[0043] The mobile phone cover plate coating structure also includes a screen printing ink layer 6, which is disposed on the back of the cover plate body 1 and surrounds the periphery of the camera hole area 10.

[0044] In the aforementioned mobile phone cover plate coating structure, the anti-fingerprint coating layer 5, the anti-reflective coating layer 4, and the cover plate body 1 are all transparent. Although the appearance coating layer 3 has a specific color, texture, or pattern, it can still be semi-transparent when its thickness is small. The screen printing ink layer 6 is used to shield the cover plate body 1 from light to prevent users from seeing the internal structure of the mobile phone through the anti-fingerprint coating layer 5, the anti-reflective coating layer 4, the appearance coating layer 3, and the cover plate body 1.

[0045] The screen printing ink layer 6 is formed on the front side of the cover plate body 1 by screen printing. During screen printing, the ink can be avoided from the camera hole area 10 by designing the mesh distribution on the screen printing plate, so as to prevent the screen printing ink layer 6 from covering the camera hole area 10.

[0046] In this embodiment, the thickness of the screen printing ink layer 6 is 10-14 μm, and it is preferably black ink.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
