Elastic rubber key and its manufacturing method. (Background note) Keypads are widely used in various electronic and communication products. With the development of technology, the requirements for conductive keys are constantly increasing. In addition to durability, easy cleanliness, and lightness and shortness, how can they have the plastic feel and obvious The sense of paragraph is also a major problem in the industry. The traditional conductive key products are composed of several single keys and a key body. Its conductivity is characterized by a layer of conductive material attached to the back of the key body. The elastic rubber body has a slanted wall design. Users can clearly feel that the paragraph when they press the button is a paragraph feeling, and the surface of the button changes according to customer needs. The general requirements are abrasion resistance and solvent resistance. Weather-resistant, because some elastic rubber bodies such as silicone are not abrasion-resistant. After a period of use, the surface font often wears out and cannot be recognized. At present, the following methods are commonly used to solve problems in the industry;

If the key product is based on the most used silicone rubber substrate In terms of the poor adhesion between silicone rubber and other materials, it is not possible to directly coat abrasion-resistant or solvent-resistant plastic materials. Therefore, surface treatment such as plasma or flame or ultraviolet radiation must be performed on the key surface before applying a layer of paint.

Description of the invention (2)), and bake the topcoat (some topcoats do not need to be baked), and then spray or pour the thermosetting resin It is matured at high temperature. This process is not only dangerous (such as the most commonly used surface treatment is to use a fire torch to sweep over the sand rubber surface, which is likely to cause the silicone rubber to burn and cause a fire). Also, because the defects on the surface of the keys cannot be compensated, the electrostatic adsorption during spraying or the generation of air bubbles during dispensing or even the adhesion of dust when semi-finished products wait for high temperature baking are unavoidable problems in this process, resulting in Bad rate is high. 2. Another newer method is a photo-hardening (UV irradiation) treatment method, as described in JP 1 1 1 4 3 5 4 9 A 2 1 _9 9 9. The steps of rubber surface treatment and varnishing are the same as above. The heat-curing type is the same. Only the UV-curable resin is selected for the final dispensing on the surface of the last button, and then cured by UV irradiation. The advantage compared to the thermo-curable resin is that the UV resin curing time is short, about 20 seconds. Left and right, it is not easy to accumulate dust, and there are fewer problems with air bubbles. However, the disadvantage is that in the selection of UV curing resin, in order to avoid shrinkage and dimensional shift, the material used has a low crosslinking density, so it is not resistant to solvents and abrasion. The surface of the button is easy to damage. In addition, whether it is a thermosetting resin or UV curing resin, it is dispensed. Therefore, no matter what shape the rubber button is, its surface is arc-shaped and cannot be diversified. The above two processes are briefly described below (please refer to Figure 1) (1) elastic rubber compression molding (Figure 1a). (2) The cured elastic rubber key products that have passed the quality control are screen-printed and printed with various colors of ink (104) that can be attached to the elastic rubber. -------- (Please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -5- 490697 Employees of Intellectual Property Bureau, Ministry of Economic Affairs Printed by the consumer cooperative A7 _ B7____ 5. Description of the invention (3) The surface of the sex rubber (1 0 2) is 'baking and curing the ink (Figure 1b), because the keys are shaped and designed, the heights are not the same'. Basically, color-by-key printing is required, and screen printing can only print a limited number of key products at one time, which cannot be printed on the entire surface at the same time as film printing. (3) Pass the printed key products through the first quality, and place the key products on the surface treatment jig manually, and then perform surface treatment such as flame, plasma treatment, etc. (4) Put the processed elastic key product on the spraying table, spray the topcoat (105), and leave it to stand until the solvent of the topcoat has evaporated, and then send it to the oven for topcoat (1 0 5), if the topcoat does not require baking, the baking action is omitted (Figure 1c). (5) The top-painted and cured key products will be passed through the second quality control to remove the defective products with dust, and the thermoset (1 0 7) will be sprayed (1 0 6) or dispensed. ) Or UV (108) curing type plastic resin for protection, coated on the surface of the button (No. ld, e, e / figure). (6) The protective resin resin-coated key products are cured by hot baking or UV irradiation. 3 · Another method is to form a button shape by die punching with diethylene terephthalate (PE butyl) or polycarbonate (PC) film, and then eject the plastic to adhere to it, and finally, print the PET film of the printed circuit. Using double-sided tape for bonding, but the bonding effect is not ideal, and there are many steps. Even if the adhesive can be used for bonding, because the stretchable length of PET or PC material itself is limited, it can only be made in size Shorter keys, the shape can not be diversified and its stretch flexibility is not enough due to the PET or PC material itself.

Description of the invention (4) Main body After the plastic film is laminated, the oblique wall part is not soft, which makes the paragraph of the button inconspicuous or disappears. Its manufacturing is briefly described as follows: (Refer to Figure 2) (1) The typeface is printed on the back of PE Ding or PC film 109. After curing, a protective film is printed on the back to protect the ink from being injected into the plastic. Destroyed (Figure 2a). (2) Use a die (1 10, 1 1 1) or use a die to stretch (convex) (Figure 2b). (3) The plastic (1 1 2) is injected into the cavity by the injection method to fill the cavity (Figure 2c). (4) Laminated with the printed soft key switch (1 1 3) of the circuit (Figure 2d). (5) Finished product (Figure 2e). 4 · Another foreign method is to directly inject the thermosetting resin into the mold and directly press mold with the elastic rubber. Since it cannot overcome the problems such as subsequent mold release and printing, it is still passed through the cured elastic rubber. The surface treatment and coating of top coat and adhesive, and bonding with the formed plastic material, must be performed one by one for each key, the steps are extremely complicated. Another limitation in the industry is that the keys are manufactured first and then printed on the surface. Because each key is different in height due to its shape, it cannot be completely on the same horizontal plane. When printing, you can only print screen-by-color and key by key. Not only is it time-consuming and labor-intensive, but the style cannot be diversified.
