Problems solved by technology

Because this scheme arranges the pattern layer 1b between the film layer 2b and the elastic layer 3b, not only the steps or procedures of the production are increased, but also the man-hours are relatively increased. On the other hand, the thickness of the keys is also increased. A less-than-ideal design for the thickness of the shaped buttons

Embodiment Construction

[0033] The technical content of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0034] See Figure 2A , A schematic diagram of the manufacturing process of the first thin key of the present invention. This figure discloses a method for manufacturing a button structure with a pattern layer button. First, as in step 100, a carrier 2 made of a transparent material of a polycarbonate film (PC Film) is prepared.

[0035] Step 102, please refer to image 3 , Punch a positioning hole 21 on the surface of the carrier 2, and the positioning hole 21 is used to provide that the carrier 2 can be positioned on the positioning post 13 of the first mold 1.

[0036] Step 104, please refer to Figure 4 , Prepare the first mold 1, in the first mold 1, there is a first mold cavity 11, the first mold cavity 11 has a plurality of second mold cavities 12, the second mold cavity 12 is used to form the shape of the button, and The bottom surface 11...

Abstract

A method for manufacturing a keystroke panel including a smooth surface, a misty surface or a grain layer is disclosed, comprising the steps of: at first, manufacturing a module whose inside bottom surface is coarse surface, smooth surface or grain surface, dropping colloid into the module and covering a carrier on the surface of the colloid, using idler wheels to roll and press on the surface of the carrier so that the carrier and the colloid are flat within the module; then irradiating with ultraviolet light in order that the colloid is hardened to form a keystroke layer attached to the carrier, afterwards, on the carrier, sequentially film-forming a bottom colour layer, functional colour layer and font colour layer as the background of the keystroke panel. Finally, hot-pressing the formed keystroke layer and the silica gel to combine both, namely, the manufacturing of keystroke panel is finished.

Description

Technical field [0001] The invention relates to a key structure, in particular to a manufacturing method of a thin key structure. Background technique [0002] When purchasing a mobile phone, general consumers, in addition to considering the functions of the mobile phone, the most important thing is whether the appearance and shape of the mobile phone is novel enough and the size is small enough. Therefore, some mobile phones print colored patterns on the casing or buttons, or directly make three-dimensional patterns on the casing to increase the added value of the product and consumers' desire to buy. [0003] See Figure 1A , The traditional three-dimensional texture production is to attach the first transparent layer 2a on the substrate 1a, attach the first color layer 3a and the color opening 31a on the first transparent layer 2a, and attach the second transparent layer on the first color layer 3a 4a, attach a second color layer 5a to the second transparent layer 4a, and use ...
