Super-thin plastic key modular and its mfg. method

Abstract

The method includes following steps: first, supplying a sheet plate; next, positioning the sheet plate by an optical positioning module; then, fabricating the sheet plate to a prearranged shape by computer numerical control (CNC) equipment; setting up a elastic body at lower end of the sheet plate with prearranged shape so as to produce ultrathin key-press body. Advantages are: reducing thickness of module of key-press, not deforming object, or producing cutting raw edge etc. caused by limitation of machine or die designed.

Description

technical field [0001] The invention relates to an ultra-thin plastic key module and a manufacturing method thereof, in particular to an ultra-thin plastic key module through the positioning of an optical positioning module and the processing of computer numerical control (Computer Numerical Control, CNC) equipment. Thin plastic key module and manufacturing method thereof. Background technique [0002] see figure 1 As shown, it is a flow chart of the manufacturing method of the existing button module. It can be seen from the flow chart that the manufacturing method of the existing button module includes: firstly, setting up a predetermined plastic mold (S100); and then, using the plastic mold, forming a thin plate ( S102), wherein the thickness is generally greater than 1 mm; then, provide a fixture for positioning the thin plate (S104); process the appearance of the thin plate (S106), such as setting graphics, symbols on the front or back of the thin plate; then Next, pu...

AI Technical Summary

Problems solved by technology

[0005] 1. In injection molding manufacturing, it is necessary to design different plastic molds for thin plates of different thicknesses;

[0006] 2. When positioning thin plates, another positioning fixture must be used for appearance processing; and

[0007] 3. When stamping the thin plate at the end, another stamping machine and the use of stamping fixtures must be used

[0008] Therefore, it can be seen from the above that the above-mentioned existing button module and its use method obviously have inconvenience and lack in actual use, and can be improved.
