Embodiment 1 and comparative example 1
[0046] The structure of the sapphire lens in Comparative Example 1 is an anti-fingerprint film layer 2, a sapphire sheet 1, a frame ink layer 5, a functional ink layer 6 and a coating layer 7 sequentially included in the thickness direction. However, the structure of the sapphire lens in Example 1 is an anti-fingerprint film layer 2, a sapphire sheet 1, an adhesive layer 4, a polymer film layer 3, a frame ink layer 5, a functional ink layer 6, and a coating film that are sequentially included in the thickness direction. Layer 7. The preparation methods of the two include the following differences. Comparative Example 1 is to electroplate the anti-fingerprint film layer 2 on the cut and polished sapphire sheet 1, and then prepare the frame ink layer 5 and the functional ink layer 6 sequentially on the other side by silk screen printing and electroplating. and coating layer 7. And in embodiment 1, carry out silk screen printing and electroplating to large polymer diaphragm 31 e...

Abstract
The invention provides a preparation method for a sapphire lens. The method comprises the steps of A, sequentially forming an ink layer and a coating film layer on one surface of a large polymer membrane 31; B, cutting the acquired large polymer membrane into two or more than two small polymer membranes as thick as the large polymer membrane by laser; C, fitting the surface, without the ink layer and the coating film layer, of each small polymer membrane with one surface of a sapphire sheet 1, and forming a glue layer 4 therebetween; and D, pressurizing the prepared sheet to remove bubble, thus acquiring the sapphire lens. The invention also correspondingly provides a window lens. According to the method provided by the invention, production efficiency of the sapphire lens can be greatly improved while the window lens has the scratch resistant capacity of sapphire; and the effects of improving a one-time machining qualification rate of the sapphire lens, improving a utilization rate of raw materials, saving raw material costs and improving bending resistant performance of the sapphire lens can also be achieved.
Description
technical field [0001] The invention relates to the field of sapphire processing, in particular to a method for preparing a sapphire lens and a window lens. Background technique [0002] Sapphire lenses are increasingly used in various wearable products due to their superior scratch resistance. However, there are many bottlenecks in the processing of sapphire lenses. The processing cycle is long, the production process is many, and the cost is too high, which restricts its mass production. Used in electronic products such as mobile phones. [0003] During the processing of conventional sapphire lenses, in order to meet the appearance requirements and use requirements of the lenses, multiple processes are required after the sapphire sheet is formed and double-sided finely polished, such as electroplating anti-fingerprint film on one side of the sapphire sheet, and on the other. One side silk screen frame shading, baking, screen printing functional ink, re-baking and electrop...
