The present invention can be more fully understood by reference to the following description and accompanying drawings, in which:
Please refer to
Step a: using drawing technology to allow a metal sheet 10 to be formed with a plurality of projection portions 11 as
Step b: placing the metal sheet 10 with projections 11 in an injection mold 20 as
Step c: placing the metal sheet 10 with the inner part of the projection portions 11 thereof combined with the PC material 30 into a stamping jig 40 as
Step d: placing the keys 50 respectively into a plurality of grooves 61 of the combination jig 60, then spreading ultraviolet resin 70 on a bottom of each key 50, pressing to attach an elastic material layer such as a rubber layer 80 thereon and finally illuminate the UV resin 70 with an UV lamp to cause it to be cured so as to allow the rubber layer 80 to be fixedly combined with the keys 50 as
Step e: cutting the rubber layer 80 to form a keyboard 90 with the metal sheet 10 on the surfaces of the needed keys 50 as
The keyboard 90 with the metal sheet 10 formed on the surfaces of the keys 50 cab be manufactured by means of the steps mentioned above; this can allow the keyboard 90 to have better quality.
The metal sheet 20 according to the present invention can be made from a metal material such as aluminum, stainless steel, gold or silver. The PC material 30 can be polyester or other rubber material.
The keys 50 can be allowed to stably combine with the rubber layer 80 by means of not only the UV resin 70 but also an adhesive or an engagement of grooves 31 and the projection portions 81 according to the present invention.
A drawing-formed metal sheet matching up with injection technology can allow a keyboard with a metal sheet on surfaces of keys to be manufactured according to the present invention. This not only enables the keyboard to have better quality but also can elevate the value of the keyboard with the metal keys.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
