Description

The writing mark structure on the surface of keyboard keys

technical field

The utility model relates to a handwriting mark structure on the surface of keyboard keys, in particular to a key surface improvement structure capable of forming embossed handwriting mark structures on the surface of materials made of the same key, which is environmentally friendly, can speed up production speed and improve product qualification rate.

Background technique

Taking a computer keyboard as an example, it is usually provided with a plurality of keys for the user to manipulate on the same keyboard. In order to facilitate the input of different commands, each button will be preset with various handwriting marks on the surface, for example, such as Arabic numerals 1-9, English letters A-Z, symbols or strings composed of multiple letters, etc. The surface of the key is marked with writing.

Since each key needs to be preset with various writing marks on the surface, relevant processing procedures must be carried out after the main body of the key is manufactured. The most common way to process the handwriting on the surface of the key is to use screen printing, but its disadvantages are that it is not durable and easy to fall off, the qualified rate of the finished product is low, and it is difficult to carry out the printing of the whole keyboard because it involves the up and down elastic structure of each key. Printing of thinner lines. At the same time, another major environmental protection problem caused by it is that printing coatings usually contain harmful chemical components, and if polyvinyl chloride (PVC) is used as the button molding material, it will cause environmental problems in recycling. In particular, the substantial increase in global computer usage has also caused a large number of problems in the disposal of such keyboard waste.

As shown in FIG. 1 , generally, after the injection molding of the key body 10 , the surface 11 thereof is a blank surface to be processed. Taking the computer keyboard key surface writing marking structure processing program as an example, please refer to FIG. 2 at the same time, the entire keyboard 12 containing many keys 10 (only a partial keyboard structure is shown in the figure) can be formed on the key 10 surface 11 after the above processing program The required handwriting marks 13. However, the handwriting marks 13 on the key surface 11 produced by the above-mentioned screen printing processing procedure are basically close to the flat type, and its control touch and the overall texture of the keyboard 12 are not ideal.

In order to improve the processing of handwriting marks on the surface of keys, the existing processing methods also include laser engraving, which can be processed more accurately and stably through the electron resonance gun and red light simulation system, and at the same time can make the handwriting marks clear and not easy to fall off. Durable. Although a laser can be used to mark the writing on the surface of the button, when polyvinyl chloride is used as the material and the paint with harmful chemical components is used, it will still cause problems for environmental protection and recycling. At the same time, it is similar to the above-mentioned screen printing processing method, and the handwriting marks processed are also flat, so it is difficult to improve its control touch and the overall texture of the keyboard.

Contents of the invention

The main purpose of the present utility model is to provide a writing marking structure on the surface of keyboard keys, which can form floating writing markings on the key surface without using paint containing heavy metals and solvents.

Another object of the present utility model is to provide a writing mark structure on the surface of keyboard keys, which can improve the non-toxic and environmentally friendly recycling requirements of such key equipment.

Another object of the present invention is to provide a writing marking structure on the surface of keyboard keys, which can further enhance the user's control quality and appearance quality.

Another object of the present invention is to provide a writing mark structure on the surface of keyboard keys, which can form a gradient relief effect on most of the parallel keys.

Another object of the present utility model is to provide a writing mark structure on the surface of keyboard keys, which is more capable of forming extremely fine writing marks that are difficult to produce by screen printing.

In order to achieve the above-mentioned purpose, the utility model proposes a writing marking structure on the surface of the keyboard key, which processes various required writing markings on the surface of the key integrally formed with the setting material; The protrusion protrudes from the surface of the key.

As mentioned above, the writing marking structure on the surface of the keyboard keys is processed by laser engraving.

As mentioned above, the writing marking structure on the surface of the keyboard keys is used for integrally forming the setting material to be foamed ABS.

As mentioned above, the writing mark structure on the surface of the keys of the keyboard is processed into gradient colors.

As mentioned above, the writing mark structure on the surface of the keyboard keys is formed by performing the above-mentioned laser engraving process on the gradient color processing of the above-mentioned keys with the set power, temperature and time.

Explanation of reference numbers:

20 buttons 21 surface 22 handwriting marks

30 keyboards 201, 202, 203 key row

Detailed ways

Please refer to Figs. 3 and 4 at first. In the preferred embodiment shown in the figure, the utility model is to process an integrated floating handwriting mark 22 on the surface 21 of the button 20 integrally formed with suitable materials. Taking a computer keyboard as an example, as shown in FIG. 4 , it can also process a keyboard 30 containing many keys 20 .

The material used to integrally form the button 20 may be foamed Acrylonitrile-Butadiene-Stryene copolymer (ABS). As a processing material, foamed ABS has the advantages of excellent strength, easy molding, good coating and engraving processability, and the appearance and touch are similar to wood. At the same time, it is a non-toxic recyclable material.

The processing of the surface 21 of the above-mentioned button 20 can be laser engraving, so as to form the writing marks 22 that are clear, not easy to fall off and durable.

Taking the above-mentioned foamed ABS as the material of the integrally formed button 20 as an example, when the laser device (not shown) performs engraving processing with the set power, temperature and time, the writing mark 22 will be made on the surface of the button according to the setting twenty one. The button 20 made of the above-mentioned foamed ABS will form an integrated handwriting mark 22 under the action of laser engraving.

As shown in Figure 5, the utility model can thus form an integrated writing mark 22 on the surface 21 of the key 20 without using paint, and at the same time, it can form different marking colors by the processing material itself during processing, such as black base material It can be reversed, or it can also form a gradient color by setting different power, temperature and time of the laser device. For example, when processing a keyboard 30 that contains a plurality of rows of 201, 202 and 203 keys 20 as shown in FIG. 20 When processing with different power, temperature and time, to form a gradient relief effect from dark green to light green or light green to dark green.

Since the utility model does not need to use paint containing heavy metals or solvents, it can be determined to be non-toxic and can better meet the strict requirements of product non-toxic regulations, and the use of foamed ABS materials can achieve the environmental protection function of complete recycling. In addition, the floating writing mark formed on the surface of the key can further enhance the user's control quality and appearance quality. At the same time, this improved structure is more suitable for rapid mass production with greatly shortened working hours to improve the pass rate. Furthermore, it can form extremely fine writing marks that are difficult to produce by screen printing.

The above-mentioned embodiments are only used for convenience to illustrate the utility model and do not limit it. Without departing from the spirit category of the utility model, various simple deformations and modifications that can be made by those skilled in the industry should still be included in the patent application. in range.
