Abstract
A light-transmission metal key is composed of a metal sheet, bosses on the metal sheet, light-transmission character holes on each boss, transparent resin poured in the recess on back of boss, and small contact on the botton of resin. Said metal key is made up through preparing thin metal sheet type key, forming light-transmission character hole, pouring transparent resin and installing contact. Its advantages are beautiful appearanace, light transmission, simple structure and low cost.
Description
The present invention relates to the button manufacturing technology, more specifically to a kind of light-transmission metallic push button and preparation method thereof.
In the prior art, the employed button of various electrical equipment is generally metal key-press and plastic press key etc., the former has wear-resisting, durable, the life-span is long, characteristics such as outward appearance is glossy, characteristic, good hand touch, but light tight, be not suitable for night or the use of dark place, latter's energy printing opacity, but its feel, outward appearance and resistance to wear are all relatively poor.At present, still do not have and a kind ofly can have both advantages, overcome the button of its shortcoming.
Purpose of the present invention just provides a kind of light-transmission metallic push button, this button can overcome the above-mentioned shortcoming on the prior art, it is long except having the metal key-press life-span, outward appearance is characteristic, the advantage that outside the advantages such as good hand touch, the price that also has plastic press key is low, printing opacity and being convenient to uses behind the built-in light emitting source in the dark.
Another object of the present invention just provides a kind of method of making light-transmission metallic push button.This method can be so that the manufacturing process of light-transmission metallic push button be simple, cost is low and the product quality height.
First purpose of the present invention adopts following technical scheme to realize: promptly on the sheet metal of a monoblock thin type, functional requirement according to various electrical equipment uses, suppress the small boss of a plurality of button shapes, make various light-transmission characters hole on the surface of small boss, in the character hole, be perfused with transparent resin.Light source, light will pass transparent resin and the light-transmission character hole directly is penetrated into the outside without obstruction if at this moment be placed with in the bottom of light-transmissive resin, so just can reach better night vision effect.
Owing to be subjected to the restriction of metal material thickness and pressing process, the height of above-mentioned said metal key-press can not be done very highly, electric equipment products for the high button of need are inapplicable, therefore, the present invention also provides another kind of light-transmission metallic push button, after adopting metal dust and plastic cement molten, make, so just can make the button of differing heights according to user's requirement with injection method.And also have the light-transmission character hole on the surface of button, and pour into transparent resin in the hole, its result of use is the same with the light sheet material button.
Advantage of the present invention is exactly: it had both had the glossy of metal material button, and luxurious appearance and wear-resisting advantage such as durable the effect of plastic press key printing opacity is arranged again, and its light transmission also are better than plastic press key and film key, the night vision better effects if.
Second purpose of the present invention adopts following method to realize.First method is to adopt to suppress the button small boss on the monoblock thin plate, and makes various light-transmission characters hole with equipment at keytop, liquid transparent resin is injected in the groove at the button back side back to be dried and polishes the two sides and get final product.
The button height of said method made is very low, be not suitable for and use on the electrical equipment of high button, the present invention also can provide second kind of manufacture method, injection moulding, promptly be raw material, after adding plastic cement and being dissolved in together, be expelled to and remove to make the higher button of aspect ratio in the mould with the metal dust, transparent resin is injected in the character hole of making printing opacity with equipment on the surface of molded button in the character hole and polishing both surfaces gets final product.
It is simple that the light-transmission metallic push button that adopts above-mentioned two kinds of methods to make has technical process, and cost is low, characteristics such as production efficiency height, and the height of button can make the button of differing heights according to user's demand, uses wide thoroughly.
With reference to the accompanying drawings, in conjunction with the embodiments, further specify the present invention.In the accompanying drawing:
Fig. 1 is the light-transmission metallic push button structural representation that metallic plate is made.
Fig. 2 is the light-transmission metallic push button structural representation of made from metal powder.
With reference to Fig. 1, on the metal blank (1) of monoblock, be shaped on button small boss (2), and be shaped on light-transmission character hole (3) in boss surface, in the groove of small boss, be marked with transparent resin (4), and be shaped on a very little contact (5) in the bottom of each button transparent resin, be used for touching conductive rubber.Above the rubber of perhaps directly will conducting electricity is bonded in.
The method of making above-mentioned light-transmission metallic push button is: the metal blank of selecting the ultra-thin and anti-bending of high-quality for use; Design and make high-precision compacting tool set according to number of keys and arrangement mode; With press device and cooperate mould to suppress the button metallic plate; With the button metallic plate that suppresses, process the character hole of printing opacity at each keytop with high-precision program-controlled equipment; In the character hole, inject liquid transparent resin, and make a very little contact, be used for touching conductive rubber,, also conductive rubber directly can be bonded in the bottom of resin to realize the break-make of circuit in the bottom of each button transparent resin; The keytop of the metal keyboard that resin is dry good and resin bottom face polish and polish and get final product.
With reference to Fig. 2, on the surface of the metal key-press made from metal dust and plastic cement (2), be shaped on light-transmission character hole (3), be connected as a single entity with rack rod (6) between each button, in the groove of button, be marked with transparent resin (4), be shaped on a contact (5) in the bottom of each button resin, be used to touch the break-make of conductive rubber control circuit, also can directly conductive rubber be sticked on the bottom of each button resin.
The method of producing above-mentioned light-transmission metallic push button is: with metal dust and plastic cement is raw material, and the percentage by weight of metal dust is greater than the percentage by weight of plastic cement.According to the requirement of the required button height of user, the design injection molding; In mould, design simultaneously the rack rod between each button, so that button is connected as a single entity; With metal dust and plastic material fused together after, be expelled to equipment and go moulding in the mould; Metal key-press after the moulding is gone out the character hole of printing opacity in its Surface Machining with program-controlled equipment; In the character hole, inject transparent resin, and be used for touching conductive rubber at small contact of the bottom of each button resin formation.Also can directly conductive rubber be sticked on the bottom of resin; Polish and polish and get final product having annotated the keytop of metal key-press of resin and resin bottom face.
