Abstract
Provided is a metallic mechanical keycap manufacture technique which solves technical defects of poor texture and abrasion resistance and complex technology of a conventional keycap. The metallic mechanical keycap manufacture technique comprises steps of: manufacturing a stainless steel keycap body by using powder metallurgy technology, wherein when the keycap body is manufactured, a hollow-out zone corresponding to a corresponding character is reserved on the key surface of the keycap body, the corresponding characters containing enclosed areas are subjected to opening hollowing out; and filling the hollow-out zone of the keycap body with glue and performing UV baking solidification in order to form a character. The stainless steel keycap body is good in texture, good in oxidation resistance, good in wear resistance, high in product precision, exquisite in detail treatment, and beneficial to the increase of a product class and the satisfaction of demands of consumers. A user is not liable to sweat when using the keycap. The character formed by filling the hollow-out zone of the keycap body with glue and performing UV baking solidification is firm, good in adhesive force, good in light transmittance, and multiple in font color selectivity. A die structure is simplified.
Description
Technical field
The present invention relates to mechanical keyboard technical field, be specifically related to the manufacture craft aspect of mechanical keycap.
Background technology
The keycap of conventional keyboard comprises following several types:
A, monochromatic plastic cement keycap: its manufacture craft is first oil spout, then radium carving font printing opacity, or font is light tight, and cost is low, but keycap is not wear-resisting.
B, bicolor plastic cement keycap: its manufacture craft is font and keycap body double-shot moulding, font printing opacity, and cost is medium, but mould is complicated, plastic cement sense is strong, texture deviation.
C, metal keycap: its manufacture craft is, 1, aluminium alloy punching press: product is coarse, cocked hat is not detailed, texture is medium, need to coordinate plastic cement could realize its function, 2, aluminium alloy, Zinc alloy die-casting process: product is coarse, cocked hat is not detailed, product processing technique is complicated, Product Precision is not high, product surface is oxidizable, abrasion resistance is poor, product surface texture is poor, and the surface treatment processing mode selectivity of alloy material is few.
Summary of the invention
In sum, the object of the invention is to solve traditional keycap texture and abrasion resistance poor, the technical deficiency of complex process, and propose a kind of metal machinery keycap manufacture craft.
For solving technical problem proposed by the invention, the technical scheme adopted is: metal machinery keycap manufacture craft, it is characterized in that described processing step is: first, powder metallurgical technique is adopted to make the keycap body of stainless steel, when making keycap body, the keyboard of keycap body reserves the vacancy section corresponding with respective symbols, is that the character comprising enclosed area carries out opening hollow out for respective symbols; Then, fill and UV baking-curing formation font at the vacancy section mid point glue of keycap body.
Described keycap body is 316L stainless steel; The operation of described powder metallurgical technique is: 1), adopt Mechanical Method or physical-chemical process raw materials powder; 2), material powder compression molding goes out the briquet corresponding to keycap body shape; 3), the sintering of briquet; 4), carry out shaping more successively, magnetic grind, sandblasting, physical vapour deposition (PVD) and anti-fingerprint oil processing.
Described keycap body is completely exposed suspension structure on keyboard cover.
Beneficial effect of the present invention is: adopt powder metallurgical technique to make the keycap body of stainless steel, and surface treatment can be diversified, and selectivity is strong, and texture is good, and be not easy during use to perspire, product non-oxidizability is strong, resistance to wear is high; Mold Making precision is high, product precision is high, product treatment of details exquisite, and product surface treatment process can be polyoxygenated, and product surface texture is best, is conducive to the class of improving product and satisfies the demands of consumers.The font formed at vacancy section mid point glue filling and the UV baking-curing of keycap body is firm, strong adhesion, light transmission are good, font color selectivity is many, and simplifies mould structure; In application process, the LED lamplight below keycap body can appear in vacancy section, and make the character on keycap body reach significantly show, character outline is clear, and font third dimension is strong.Stainless steel metal keycap of the present invention is more attractive in appearance, generous, exquisite, more can embody Time Technology sense, brings in a kind of brand-new consumption experience to consumer.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of keycap that present invention process obtains;
Fig. 2 is the keycap side-looking structural representation that present invention process obtains;
Fig. 3 is the keycap backsight structural representation that present invention process obtains.
Embodiment
Below in conjunction with accompanying drawing and the preferred specific embodiment of the present invention, technique of the present invention is further described.
Shown in Fig. 3, the step of metal machinery keycap manufacture craft of the present invention is: first, powder metallurgical technique is adopted to make the keycap body of stainless steel, when making keycap body, the keyboard of keycap body reserves the vacancy section corresponding with respective symbols, be that the character comprising enclosed area carries out opening hollow out for respective symbols, such as: O, P, A, 6,8,9 etc. comprise enclosed area character and carry out opening hollow out; Then, fill and UV baking-curing formation font at the vacancy section mid point glue of keycap body.
Keycap body is 316L stainless steel; The operation of described powder metallurgical technique is: 1), adopt Mechanical Method or physical-chemical process raw materials powder, Mechanical Method includes: mechanical crushing and atomization; Physical-chemical process includes: couple corrosion method, reducing process, chemical combination method, reduction-chemical combination method, vapour deposition process, liquid phase deposition and electrolysis; 2), material powder compression molding goes out the briquet corresponding to keycap body shape; 3), the sintering of briquet, the briquet after shaping makes it obtain required final physical mechanical performance by sintering; Sintering is divided into again unary system to sinter and heterogeneous sintering, and for the solid-phase sintering of unary system and polynary system, sintering temperature is lower than the fusing point of metal used and alloy; For the liquid-phase sintering of polynary system, sintering temperature is generally low than the fusing point of wherein infusibility composition, and higher than the fusing point of low-melting constituent.Except ordinary sinter, also has the sintering process that loose sintering, infiltration method, pressure sintering etc. are special; 4), carry out shaping more successively, magnetic grind, sandblasting, physical vapour deposition (PVD) and anti-fingerprint oil processing.
The advantage that the present invention adopts powder metallurgical technique to make 316L stainless steel keycap body has: because powder metallurgy process can be pressed into the pressed compact of final size, and do not need or seldom need machining subsequently, therefore greatly can save metal, reduce product cost.With powder metallurgy process, the loss of metal only has 1-5%, and when producing with general casting method, the loss of metal may reach 80%.In addition, due to powder metallurgical technique not molten material in Material Manufacturing Process, the impurity being mixed into and being brought by crucible and deoxidier etc. is not just afraid of yet, and sintering generally carries out in vacuum and reducing atmosphere, be not afraid of oxidation, can not give any pollution of material yet, can the material of high-purity.Powder metallurgical technique can ensure correctness and the uniformity of material composition proportioning.Sintering temperature is lower than the fusing point of metal used and alloy.
Described keycap body is completely exposed suspension structure on keyboard cover, is convenient to consumer and cleans keyboard dust and impurity.
