Description

Keyboard cover manufacturing method

The invention relates to a method for manufacturing a keyboard cover, in particular to a method for manufacturing a metal keyboard cover.

Due to the global sales of 3C information products and high-end home appliances, the metal casing has already become the basic equipment for the products. In general, in addition to high strength and noble texture, the metal casing can provide better heat dissipation and prevent the electronic components from shortening their life due to the high internal temperature.
However, the construction of part of the outer casing is not easy to make directly from sheet metal. Please refer to Figure 1 for a schematic diagram of the manufacturing method of the conventional metal keyboard cover. As shown in the figure, a plurality of perforations 121 are formed by stamping and forming on a metal plate 12, and a plastic flat plate 14 having a plurality of perforations 141 is also formed by plastic injection molding, and the metal plate 12 is further The plastic 14 is bonded to complete the manufacture of the keyboard cover 16 having the predetermined thickness 167 of the keyhole 163.
The completed keyboard cover 16 includes a metal plate 161, a plurality of button holes 163, and a predetermined thickness 167 of the button holes 163 formed by the metal plate 161 and the plastic plate 165.
The structure of the keyboard cover 16 is required to use two separately fabricated components to adhere to each other. Although the texture of the metal casing can be possessed, a plastic flat plate 163 is blocked inside, and the heat dissipation effect is greatly reduced. In addition, when the metal plate 161 is attached to the plastic plate 165, precise alignment is required, resulting in additional human and material costs. Moreover, the quality of the bond also affects the durability of the product, and it is easy to peel off and damage due to temperature changes and environmental influences.

The main object of the present invention is to provide a method for manufacturing a keyboard cover, and more particularly to a method for manufacturing a metal keyboard cover.
A secondary object of the present invention is to provide a method for manufacturing a keyboard cover, which can be used to manufacture an integrally formed metal keyboard cover by a press forming method.
In order to achieve the above object, the present invention provides a method for manufacturing a keyboard cover, comprising: providing a metal plate; forming a plurality of pre-openings at a predetermined position of the metal plate; and forming a plurality of openings around the plurality of pre-openings a flange; and removing the unevenness of the top end of each flange to form a keyboard cover.
In an embodiment of the method for manufacturing a keyboard cover, each pre-opening is located at a central position of the corresponding opening.
In an embodiment of the method for manufacturing the keyboard cover, each of the pre-openings is preferably a rounded rectangle.
In an embodiment of the method for manufacturing a keyboard cover, the size of each pre-opening is calculated according to the size of each opening and the height and wall thickness of the flange.
In an embodiment of the method for manufacturing a keyboard cover, each of the pre-openings may be separately selected by one of stamping, shearing, forging, milling, and drilling.
In an embodiment of the method for manufacturing a keyboard cover, the step of removing the top ends of the flanges may be selected as one of a step of cutting and a step of milling.
In an embodiment of the method for manufacturing the keyboard cover, the metal plate may be selected from the group consisting of stainless steel, copper, aluminum, magnesium alloy, titanium alloy, aluminum-magnesium alloy, nickel-based superalloy, tungsten, molybdenum and cobalt. A thin metal plate.
In an embodiment of the method for manufacturing a keyboard cover, wherein the keyboard cover is integrally formed.

Please refer to FIG. 2, which is a flow chart of an embodiment of a method for manufacturing a keyboard cover of the present invention. As shown, the method of fabricating the keyboard cover of the present invention includes the step of providing a metal sheet, such as step 201. The metal plate may be selected from the group consisting of stainless steel, copper, aluminum, magnesium alloy, titanium alloy, aluminum-magnesium alloy, nickel-based superalloy, tungsten, molybdenum or cobalt.
Then, a plurality of pre-openings are formed on the predetermined position on the metal sheet, as in step 203. Openings and flanges are formed in each of the pre-openings by press forming, as in step 205.
Finally, the top end of each of the flanges produced in the foregoing steps is removed from the unevenness to form a keyboard cover, as in step 207. By using the manufacturing method of the keyboard cover of the present invention, a metal keyboard cover which is integrally formed into a thin metal shell and integrally formed can be manufactured.
In one embodiment of the invention, each of the pre-openings may be separately selected for one of stamping, shear forming, forging, milling, and drilling.
Please refer to FIG. 3 and FIG. 4 , which are respectively schematic diagrams of steps of an embodiment of a method for manufacturing a keyboard cover of the present invention. As shown in the figure, in the present embodiment, a plurality of pre-openings 36 are formed in the predetermined position on the metal sheet 32 by a press forming step. Preferably, each pre-opening 36 is located at a central position of the corresponding opening 34. The shape of each pre-opening 36 is a variety of geometric shapes or arbitrary shapes in accordance with the requirements of the opening 36, wherein a rounded rectangle is preferred, as shown in FIG. In addition, the size of each pre-opening 36 is determined by the size of each opening 34 and the height of the predetermined flange 42 and the wall thickness to calculate the extrusion effect of the material.
After the openings 34 and the flanges 42 are formed by the steps of stamping and forming around the pre-openings 36, since the metal material is deformed by pressing in the pressing step, the top end 44 of the flange 42 is inevitably formed to be partially uneven, and one can be utilized. The step of cutting forming or the step of milling forming removes the unevenness of the top end 44 along a cutting line 441 to complete the manufacture of the keyboard cover 46.
The finished keyboard cover 46 includes a flat portion 461 and a plurality of button holes 463, and each of the button holes 463 has a flange 465.
By using the manufacturing method of the keyboard cover of the invention, the production of the integrally formed metal keyboard cover can be completed.
The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention, that is, the shapes, structures, features, methods, and spirits of the present invention are equally Variations and modifications are intended to be included within the scope of the invention.
