Abstract

An electronic switch device with characters and pattern on its key surface is made up of silica gel through pugging silica gel as raw material and hardening agent, hot press for shaping transparent key body, flat print with non-silica-gel ink, baking, spraying a layer of opaque silica gel ink, baking again and removing non-silica-gel ink from key surface. Its advantages are clear marker, simple making process.

Description

A kind of switchgear of electronic musical instrument and the manufacture method of button thereof

The present invention relates to the manufacture method of its button of switchgear of electronic musical instrument.

In the prior art, general button product, telecommunication device, computing machine, electronic musical instrument etc. when rather dark, often can't clearly be recognized the distinguishing mark of its each button, cause the inconvenience of using.The button that light-permeable is arranged in some telecommunication device, but its be designed to distinguishing mark on this key face light tight outside, around the button and the key body light-permeable, cause the relative significant degree of distinguishing mark to reduce, and the manufacture process of button is too complicated.

The objective of the invention is to avoid above-mentioned deficiency and provide a kind of showing not indicate light-penetration key and manufacture method thereof.

The present invention is achieved in that a kind of switchgear of electronic musical instrument, comprises button, key base, spring, and button is made up of silica gel material, and different signs is arranged on the key face.

A kind of manufacture method of button: with the silica gel raw material, rigidizer places mixing roll mixing;

With the semi-solid raw material after mixing,, form the silica gel push-button body of light-permeable by the hot press hot forming;

Adopt on the key face that offset printing is printed on this silica gel push-button with required font of each key face or pattern with non-silica gel printing ink;

After being 100 ℃～150 ℃ baking 8-12 minute through baking temperature, the even lighttight silica gel printing ink of spraying one deck on this silica gel push-button;

The process baking temperature is 150 ℃～220 ℃ and toasts after 8-12 minute, and the non-silica gel printing ink on the silica gel push-button key face is struck off, and font or pattern on it are revealed, and is the light-permeable shape.

Description of drawings:

Fig. 1 is the button figure of the embodiment of the invention.

Fig. 2 is a manufacture method process flow diagram of the present invention.

Fig. 3 is the button figure of one of embodiment of the invention.

Below in conjunction with accompanying drawing and embodiment the present invention is further described.

A kind of electronic musical instrument switchgear as shown in Figure 1, comprises button, key base, spring suppport, spring, and wherein button is made up of silica gel material, is printed on distinguishing mark on the key face.The button light-permeable shows the distinguishing mark on the key face, covers the light tight silica gel printing ink of one deck on the key face.

The manufacture method of this button is as follows: earlier with the silica gel raw material, rigidizer places mixing roll mixing, again half after mixing consolidated the shape raw material, is 150 ℃～190 ℃ by hot press in temperature, through 8～12 minutes hot formings, form the silica gel push-button body of light-permeable, the distinguishing mark that adopts offset printing that non-silica gel printing ink is hacked dew with each key face again is printed on the key face of this silica gel push-button, through baking temperature is that 100 ℃～150 ℃ baking is after 8～12 minutes, on this silica gel push-button, evenly smear the lighttight printing ink of one deck, be 150 ℃～220 ℃ bakings 8～12 minutes through baking temperature again, at last the non-silica gel printing ink on the silica gel push-button key face is struck off, distinguishing mark on it is revealed, can the printing opacity shape.

In order to obtain to appear the photochromic of light, can place mixing roll mixing with silica gel raw material, rigidizer pigment.

The switch dress system or the key board unit that can be used for electronic musical instrument by the button of said method manufacturing.As mellotron, electronic music toy etc.

Also can be used on the telecommunication devices such as telephone set, device for mobile communication, and the button or the switchgear of computing machine, counter.

This button has the distinguishing mark clear display on its key face, and manufacture method is simple, and production cost is low.
