Key cap of keyboard and method for making same

Abstract

A key cap of keyboard and its manufacture method is disclosed, whose key cap includes a keying and a protective layer and the designed signal sign or figure are printed on the keying or word, sign or figure are printed on the back of protective layer which is then adjacent to the keying. The manufacture method of key cap includes supply a protective layer, printed figure on the back of protective layer, prepare a keying lower die of keyboard with at last one die cavity and make the protective layer move to the corresponding position of the keying lower die; prepare a keying upper die of keyboard with at least one hole for injecting plastic raw material; inject plastic raw material into the hole; get keying out. By using the method, sign of key cap has more abundant installation and is not easy to fall and its quick and convenient.

Description

technical field [0001] The present invention relates to a keycap of a keyboard and a manufacturing method thereof, in particular to a structure and a method applied to touch parts printed with symbols on the keycap of a computer keyboard, so that the symbols of the keycap are more diverse and changeable. And protect it from falling off. Background technique [0002] Due to the popularization and application of computers, keyboards for inputting data are becoming more and more important, especially for diversified and multi-functional input, the symbols on it are often arranged multiple times on a keycap, such as English letters, numbers, or patterns etc. [0003] But there is following shortcoming usually in present common key cap: [0004] 1. The characters, symbols or patterns on it are usually made by printing, so after a period of use, especially when the computer keyboard is used frequently every day, it is very easy to fall off due to continuous touch or sweat erosio...

AI Technical Summary

Problems solved by technology

[0004] 1. The characters, symbols or patterns on it are usually made by printing, so after a period of use, especially when the computer keyboard is used frequently every day, it is very easy to fall off due to continuous touch or sweat erosion, often causing users troubles in use

[0005] 2. The surface of the general keycap is usually slightly concave, or provided with protruding punctuation or ribs for better tactile feeling and operation. Its shape is not flat, which will inevitably lead to difficulties in printing, and it is easy to cause deviation. Increase the ratio of defective products

[0006] 3. In order to make it easy for users to distinguish, the symbols on the keycaps are usually distinguished by different colors, which requires pad printing in batches, which will easily cause offset and processing difficulties

[0007] 4. The surface of the keycap is not easy to clean, and the cleaning agent or cleaning wax may clean the printed text on the surface

However, the manufacturing process of this technology is also complicated, and the application on patterns is still limited

[0010] Therefore, how to propose a novel computer keyboard for the above-mentioned problems, to improve the shortcoming that the traditional keycap symbols are easy to fall off, has been the ardent expectation of users for a long time, and if a fast and convenient symbol printing method can be provided, It has good industrial applicability. Based on many years of experience in research and development of computer peripheral related products, the inventors have thought and improved ideas, poored their personal professional knowledge, and finally developed a kind of Improved structure of keyboard keycap and manufacturing method thereof
