Embodiment Construction

[0041] see Figure 1 to Figure 3 , figure 1 It is a top view of a keycap 1 according to a preferred embodiment of the present invention, figure 2 for figure 1 A cross-sectional view of the middle keycap 1 along the line X-X, image 3 It is the main flowchart of the method for making keycaps according to the present invention. As shown in step S100, the method for making a keycap mainly uses in-mold transfer printing to form the cap body 12 with an ink layered structure 14 attached thereon; as shown in step S200, the method for making a keycap is followed by The high-energy optical engraving method forms a pattern 16 on the ink layered structure 14. In this embodiment, the pattern 16 is a letter A, but the invention is not limited thereto. Finally, as shown in step S300 , in the method for manufacturing a keycap, a light-transmittable protective layer 18 is formed on the ink layered structure 14 to cover the pattern 16 . In this way, the production of the keycap 1 utilize...

Abstract

The invention relates to a key cap and a method for making the key cap. According to the manufacture method, an in-mold transfer printing method is used for injecting and forming a cap body, and an ink layer type structure is attached on the cap body; then, patterns are formed on the ink layer type structure by a high-energy optical carving method; and finally, a light transmission protection layer is formed on the ink layer type structure and covers the patterns. Compared with the prior art, the key cap and the method have the advantages that the manufacture time of forming the cap with patterns at the upper sides, such as key caps used by backlight keyboards and the like can be shortened, in addition, the in-mold transfer printing method is utilized, the combination intensity between the ink layer type structure and the cap body can be enhanced by using the in-mold transfer printing method, and the peeling possibility of the ink layer type structure is effectively inhibited.

Description

technical field [0001] The invention relates to a key cap and a method for making the key cap, in particular to a key cap with a pattern on it and a manufacturing method thereof. Background technique [0002] Generally, keycaps are mostly made by injection molding. If it is necessary to form a pattern on the keycap, the pattern is formed in an additional process independent of the aforementioned injection molding. For example, keycaps used in backlit keyboards usually have a transparent cap body firstly, and then sequentially print or spray multiple layers of ink on the surface of the cap body. The pattern is formed by etching the aforementioned multi-layer ink with laser. Finally, a protective adhesive layer is sprayed on the multi-layer ink, especially on the pattern, and the protective adhesive layer is hardened. At this point, the keycap with the pattern is complete. Therefore, the above-mentioned keycap needs to go through multiple manufacturing processes, which is ...
