Problems solved by technology

[0002] With the popularity of mobile phones, people's requirements for various performances of mobile phones are also gradually increasing, especially the camera performance of mobile phones, which not only requires the ability to take high-quality, high-resolution photos, but also requires the camera lens to have a certain strength and Abrasion resistance, the current design trend of mobile phones tends to be thinner, and since most mobile phones use a single-lens mode, while reducing the thickness of the mobile phone, while ensuring the quality and thickness of the camera, the single-lens mode can only Choose to ensure the quality of the photos, which leads to the camera lens of the mobile phone often protruding from the outer shell of the mobile phone, such as Samsung's i9200 mobile phone, Apple's iphone 6 mobile phone
The protrusion of the camera lens is not only unfavorable for its anti-fouling and stress, but also more susceptible to scratches and abrasions. Since the camera lens is a highly precise optical element, it is generally made of glass or plastic, and its wear resistance is often within a certain range of strength. It is effective internally. When it is exposed to metal sharp objects and acid-base corrosive substances, scratches and pitting will often appear on the surface, resulting in dark shadows and line marks in the image formed by shooting, which will affect the shooting performance of the mobile phone.

Abstract

The invention discloses a wear-resistant camera lens, which comprises a camera lens. A layer of zirconia nanoparticle film is provided on the surface of the camera lens. The thickness of the zirconia nanoparticle film is 0.3-1.5 μm, and is sprayed by high-pressure spraying. A zirconia nanoparticle film is formed on the surface of the camera lens. By spraying a layer of zirconia nanoparticle film on the surface of the camera lens, due to the high light transmittance of zirconia nanoparticles, a wear-resistant layer is formed on the surface of the camera lens, and at the same time, it has an impact on the amount of light entering the camera lens and the captured image. little. After testing, the zirconia nanoparticle film formed on the surface of the camera lens has a zirconia content of more than 75%, a refractive index of 1.84, and excellent light transmittance. It is obtained through the test of the wear resistance of the coating film. Rarely, the front and rear light transmittances have little change, thus, the wear-resistant camera lens of the present invention has outstanding wear-resistant performance, which solves the problem of non-wear-resistant existing camera lenses.
