Abstract
The present invention provides a rubber key manufacture method and a rubber key made by the method. A key transparent surface layer glue and key bottom layer glue are made in two stages; a character is printed at the bottom part of the transparent key surface layer glue; after agglutinated, the printed character is clamped between the two layers of glue. Thus, the printed character can be seen from the front side of the surface layer glue by permeating the surface layer glue, and can not disappear by press and abrasion.
Description
The present invention relates to a kind of manufacture method of sheet rubber button.
Rubber key is widely used on the button of phone, calculator, computer, automobile and aircraft and other various instrument etc.In the prior art, the manufacture method of sheet rubber button is to place silica gel in all one's life on main pressuring template, after finishing, pressing mold forms a button film, and it is inserted in the printing apparatus, see through silk quality seal net and font is printed on this button film with a brush, Fig. 1 and Fig. 2 show the flow process of this method.So the font that stamps on button film surface is pushed the wearing and tearing that cause institute's lettering body because of the use of a period of time easily, even disappears.
The objective of the invention is to overcome above-mentioned shortcoming and propose a kind of method of making the sheet rubber button.
For this reason, the present invention proposes a kind of manufacture method of sheet rubber button, may further comprise the steps: the transparent adhesive tape mold pressing that will be used for the button top layer is made, stamp reverse font at the back side of this surface layer adhesive of making, again when pressing mold is made button bottom film, a side that is printed on font that makes surface layer adhesive is surperficial involutory with bottom glue down, and heating makes surface layer adhesive and bottom glue bond then.
This sheet rubber button constructed in accordance since printing type face between two-layer rubber, so it can be owing to long-time the use be caused the font wearing and tearing.
Below, will describe the present invention in conjunction with the accompanying drawings in detail, among the figure:
Illustrated in figures 1 and 2 is the technological process of making the sheet rubber button in the prior art;
Fig. 3 and the technological process that Figure 4 shows that manufacturing sheet rubber button of the present invention.
Consult Fig. 3 and Fig. 4, in the method for the invention, earlier a transparent living silica gel 101 is inserted in the button surface layer adhesive molding press 10, behind pressing mold, form button surface layer adhesive 102.This button surface layer adhesive surface is inserted in the printing anchor clamps 20 down, fixedly clamped to be subjected to it.Printing anchor clamps 20 top devices have silk quality seal net 21, with a brush 22 reverse font are seen through that this silk quality is printed net 21 and the back side that is imprinted on button surface layer adhesive 102, and making it to look from transparent button surface layer adhesive front is a correct font.The button surface layer adhesive that again this is completed for printing makes its position, the neither change of distance with a vacuum attracting instrument 31 stable picking up.
Then, silica gel 301 is inserted and is prepared pressing mold in the main mould machine 30 throughout one's life, at this moment, with vacuum attracting instrument 31 and the button surface layer adhesive 102 of being inhaled thereof move to bottom with give birth to silica gel 301 directly over the appropriate location, put down button surface layer adhesive 102 and make it the surface up, it then prepares to join with giving birth to silica gel 301 with the bottom for the treatment of pressing mold in back side of printing type face; Main molding press 30 is closed with pressing mold, and form button bottom glue; Heating so that this two-layer film is bonding, forms double-deck button sheet rubber of the present invention again.
In sum, the invention provides the button that a kind of double-layer rubber sheet constitutes, it is made by double-deck sheet rubber pressing mold, and font is printed in the back side of transparent button surface layer adhesive, make it to look, also can see printed font from the positive surface layer adhesive that sees through of surface layer adhesive; And when bonding, its printed font becomes and is clipped between upper strata glue and the lower floor's glue, and can not cause the font wears because of pushing for a long time.
Claims (1)
1. the manufacture method of a sheet rubber button, it is characterized in that it may further comprise the steps: the transparent adhesive tape mold pressing that will be used for the button top layer is made; Stamp reverse font at the back side of this surface layer adhesive; Again when button bottom film pressing mold is made, what make described top layer film is printed on font one side surperficial involutory with bottom glue down, makes described surface layer adhesive and bottom film bonding then.
