Description of the invention (/) The present invention relates to a method for manufacturing a light-transmitting key, especially a method for manufacturing a light-transmitting key that can be mass-produced by screen printing. With the improvement of industrial standards, the quality of industrial products has also been relatively greatly improved. In addition to paying attention to functionality, we have also focused on k-view beautification and practical upgrades. • Taking the rubber buttons that are often used in various telephones as examples, The conventional structure is only that the surface of the key block of the key is provided with numbers, symbols or other letters for the user to identify and choose. This type of simple identification function has been significantly changed in recent years. For example, the keys are transparent. There is a light source inside the button. When the phone is used, it can produce a luminous effect on the surface of the button. In addition to the beautifying effect, it also has the function of guiding identification of Ye Lu. "The traditional method of such transparent rubber buttons is The light rubber is integrally formed to form a key body. A plurality of protruding key parts are formed on the key body, and the surface of the key body is coated with ink, and then part of the ink is carved off the surface of each protruding key part manually Forming numbers, patterns and other symbols, this manual method is naturally not in line with production efficiency. And the practice of Juqian's improvement is to engrave it by laser. The digital symbols on the buttons, this laser process is faster and more efficient than traditional methods, but it still has its stumbling blocks. For example, laser machines are very expensive equipment. The industry must purchase them at a very high cost, so it is necessary to pay Large use cost. Furthermore, there are some limitations in the implementation of the laser manufacturing method itself. For example, it can only engrave a digital pattern on one button body at a time, because it is carried out piece by piece. Therefore, the construction efficiency is still low. • Because the depth of laser cutting is precise and consistent • When the thickness of the ink on the surface of the button is unevenly coated and the lines are too thick or too thin * may make -3- This paper size is applicable to the Chinese National Standard (CNS) A4 specification ( 210X297mm) (Please read the precautions on the back before filling in this page),-'° A7 B7 V printed by the Beigong Consumer Cooperative of the Central Bureau of Economic Affairs of the Ministry of Economic Affairs, and the invention description (2) caused by incomplete digital patterns Defective rate. It can be seen from this that the traditional light-transmitting button is obviously not ideal, and further review and improvement are necessary. Therefore, the main purpose of this creation is to provide a method for manufacturing a k-light button. It is mainly formed on a rubber body which is integrally formed with a plurality of protruding button parts. Spray a layer of opaque paint on the surface of the part, and then peel off the paint on the surface of the key part together with the ink, then apply a colored paint on it, and then print the reversed digital symbol with a screen printing · and print on it. Wear-resistant ink, complete a transparent button. In order to further understand the above-mentioned objectives and detailed steps of the present invention, the following review details are attached with the drawings as follows: (1) Circle part: The first picture is a schematic diagram of the appearance of the present invention after being molded according to the body .

Section of the invention description (J) (2) · Drawing number part (1 0) Button body (1 2) Ink (1 4) Colored paint (1 1 ) Button part (1 3) ¥ Translucent paint (1 5) Opaque paint The specific implementation steps of the invention printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economics are detailed as follows: 1. The step of "key forming" The light-transmitting primary color rubber is integrally formed into a key body (10) (as shown in the first figure), and the key body (10) is formed with a large number of key parts (11) that protrude from the surface and have different sizes. The key body (10) is a conventional technology and is not the subject of the present invention, so it will not be described in detail. A "ink printing" step: it mainly uses screen printing technology to coat a layer of ink (12) on the surface of each button part (1 1) of the button body (1 0) (as shown in the second picture) • and bake it dry. A step of "coating with opaque paint": after printing ink (12) on the surface of each button part (1 1) of the button body (1 0), it is printed on the button body (1 0) and its button part (1 1) Spray a layer of opaque paint (13) on the surface (as shown in the third picture), the opaque paint (1 3) can be ink, gray or other dark opaque colors as needed, which is located on the button The opaque paint (13) on the surface of the part (1 1) covers the upper layer of the ink (1 2). A "stripping" step: opaque coating on the key body (1 0) -5- (please read the precautions on the back before filling in this page) This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 Cli) A7 B7 printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of the invention (/) Material (13) After air-drying, the opaque coating (13) on the surface of the button part (11) will be peeled off (Four pictures shown) • Since the button part (11) has a layer of ink (12) under the opaque paint (13), it can facilitate the peeling of the opaque paint (13) on it. (12) It is together with the upper layer of opaque paint (13)-and peeled off. At this time, the surface of the button part (1 1) will reveal the original color of the rubber, and it is for those who can transmit light. One step of "colored paint printing": main It is on the surface of the button part (1 1) where the primary color of the rubber is exposed, and is provided with a colored paint (1 4) by screen printing (as shown in the fifth circle) * This colored paint (14) is the back button part (1 1 ) The color of the displayed numbers, patterns or symbols, and the colored paint (14) is still transparent; (1 1) In addition to numbers, there may be other letters or symbols, so a button part (1 1) may have two or more colors of colored paint (14), if set with more than two colored paint (14) | You need to print with different screens and different patterns set on them. A "digital printing" step: this step is still carried out on the surface of the key part (1 1) of the key body (1 〇), the main purpose is to set the corresponding number, letter or symbol on each key part (1 1), The specific formation method is still screen printing with opaque paint (15), but the numbers, letters or symbols on the screen are reversed negative graphics. Therefore, when the graphics on the screen are converted to buttons Part (1 1), except for numbers, letters and symbols, etc. are printed with opaque paint (15) (such as the sixth circle -6 This paper size is applicable to China National Standard (CNS) A4 specification (2 丨0X297mm) II II installed __ I ordered I i-if (please read the precautions on the back before filling in this page) A7 B7 SHS29 5. Description of invention (shown below) • Within numbers, letters and symbols In other words, the colored paint (14) presents its font or circle shape so as to be contrasted with the opaque paint (15) of other parts of the button part (11) to complete the formation of button numbers or symbols. ^ A "Step I for printing the wear-resistant layer: in principle, after completing the previous step, that is, a complete key has been formed, but due to the high frequency of the surface of the key part (1 1) contacting the user's fingers, it is easy to rub and make it The paint on the surface is peeled off, so a wear-resistant layer made of ink is screen printed on the surface of the button part (1 1) to prevent the paint from peeling off, and then the button is made. As can be seen from the above, the present invention uses multiple screen printing steps to set numbers on the key portion (1 1) of the key body (1 0), because the surface of the key portion (1 1) is sequentially printed with colored paint (1 4 ) And white opaque paint (15) • In use, the light source located inside the key body (10) will pass through the rubber body of the key part (1 1), colored paint (1 4) and opaque paint ( 1 5) The reversed part of the white is transmitted outward (as shown in the seventh figure), and from the button body (10), it can be seen that each button part (11) has a number with a different color. Therefore, the above-mentioned light-transmitting key process has at least the following advantages: (1) Mass production: The present invention can use the aforementioned screen printing process to perform ten key body at the same time every working time, so it can facilitate mass production. Compared to both The laser process can only be performed on a single button at a time, which is more productive. (2) Low defect rate: due to the accurate graphic conversion of screen printing, and its printing -7-This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) III 1 IIIM (please read the notes on the back first (Fill in this page) A7 B7 printed by Beigong Consumer Cooperative of the Central Bureau of Economics of the Ministry of Economic Affairs ----------- V. Description of the invention (4) The brush layer is evenly distributed • Therefore, the probability of errors in its manufacturing process Very low, and can ensure product quality. (3) Low production cost: because the laser machine is not used in the present invention, for the industry, there is no need to spend a lot of money to purchase equipment, so 4 [effectively reduce production costs. In summary, the present invention does have the aforementioned advantages and also has The high industrial utilization price, which has both novelty and progress, and meets the requirements of the invention, and filed an application according to law.
