Problems solved by technology

[0003] Benefiting from the ever-expanding mobile phone market, the demand for mobile phone lenses is also increasing year by year. Traditional mobile phone lens materials are generally PC (polycarbonate), PMMA (polymethyl methacrylate) or a composite of the two. Material, silk screen, laminating, CNC die-cutting, cleaning and inspection and packaging steps, the thickness of the prepared lens is generally 0.6-2mm, with the continuous rise of raw material prices, labor and factory use costs continue to increase, coupled with increasing market competition Intensified, mobile phone spare parts manufacturers have to fight price wars while ensuring quality. How to effectively reduce the cost of lenses has become the primary problem facing mobile phone lens manufacturers
The current printing steps in the production process of mobile phone lenses usually use manual single-page printing, which has low processing efficiency, high labor costs, and poor quality of finished products
Moreover, the surface hardness of the existing mobile phone lens is low and easy to scratch

Abstract

The invention discloses a mobile phone lens which comprises a PC layer, an ink pattern layer, an adhesive layer and a PET layer which are sequentially stacked, and is 0.6 to 0.8 mm thick. The mobile phone lens is lighter and thinner than a conventional lens, and the screen-printing ink pattern layer is disposed between the PC layer and the PET layer, does not affect the light transmittance of thelens, and is well protected, thereby avoiding scratching patterns and significantly improving oxidation and corrosion resistance. When the mobile phone lens is used, the PC layer is close to the inside of a mobile phone, the PET layer is located on the surface of the mobile phone, the mobile phone lens is of high surface hardness and strong scratch resistance and wear resistance, the brightness ofPET increases with the wear and tear during use, and after several years of use, the mobile phone lens remains bright as new. The invention also discloses a production process of the mobile phone lens, which has high automation degree, high production efficiency and low production cost, is easy to operate, and thus is suitable for mass industrial production.
