Problems solved by technology

However, the large-screen windows made by this bonding method often cause the window lenses and plastic parts to be easily separated due to insufficient bonding strength.
Furthermore, there are many details when bonding, such as the surface cleanliness of the bonding surface, temperature, pressure, etc. need to be considered

Embodiment Construction

[0017] First, please also refer to the figure 1 , figure 2 and image 3 , which are respectively the front perspective view, rear perspective view and figure 2 Sectional view of the AA line segment. As shown in the figure, the window lens 10 of the present invention mainly includes a glass lens 12 with a light-blocking film 14 pasted on its bottom surface; and a frame 16 wrapped around the glass lens 12, and the material of the frame 16 is plastic.

[0018] The above light blocking film 14 may be made of polybutylene terephthalate (PBT). In addition, at least one positioning hole 18 is provided on the glass lens 12 for positioning the glass lens 12 when the plastic frame 16 is shot.

[0019] Next, related descriptions are provided for the manufacturing process of the window lens 10 of the present invention. Please also refer to Figure 4(a) ~ 4(b) and Figure 5 . First, as described in step S1, a glass lens 12 and a light-blocking film 14 are provided, as shown in Fi...

Abstract

The invention provides a method for manufacturing a window lens. The method includes the steps: providing a glass lens; attaching a light-stopping film onto the bottom surface of the glass lens; and enveloping a frame on the periphery of the glass lens. As the frame is enveloped on the periphery of the glass lens, the bonding strength of the frame and the glass lens is high, and the manufacturing cost of the whole window lens can be saved.

Description

technical field [0001] The invention relates to a method for manufacturing a window lens, in particular to a method for manufacturing a window lens that is directly wrapped around the window lens to form a frame. Background technique [0002] With the development of science and technology and people's demand for high-quality electronic products, electronic products with large screen windows have become the goal that people are eager to pursue. At present, the production method for large-screen windows is generally to first coat and print the window lenses, and then use an adhesive, such as 3M double-sided tape, to glue the above-mentioned coated window lenses to a plastic part. combine together. However, the large-screen windows made by this bonding method are often easy to separate from the plastic parts because of insufficient bonding strength. Furthermore, there are many details in bonding, such as the surface cleanliness of the bonding surface, temperature, pressure, e...
