In another kind of embodiment, the Curved surface metal of 3D described in step b part 1 one side bonding with moulding 3 also can be the concave face of described 3D Curved surface metal part 1.
As Figure 2-Figure 5, in a preferred embodiment, step b be included in the edge of described moulding 3 one-body molded go out locating button 4.Circumferentially multiple locating button 4 can be set in uniform intervals distribution.
In different embodiments, in step c, 3D coil can multi-turn around being scattered in circle (as shown in Figure 4), square or polygon etc.
As shown in Fig. 5-Fig. 6, in a preferred embodiment, in steps d, during injection moulding, reserve dead slot 7 in the position of described contact 6, exposed by described dead slot 7 to make described contact 6.
Consult Fig. 1 to Fig. 6, in one embodiment, a kind of 3D loop product, comprise the 3D coil 5 of multi-turn around distribution that overall profile is pot shape, 3D coil 5 can be processed by the 3D Curved surface metal part 1 of pot shape, the one side of described 3D coil 5 bonds with the moulding 3 of the pot shape matched, the another side integrated injection molding injected plastics material part of described 3D coil 5, described 3D coil 5 is coated on inside by described injected plastics material part and described moulding 3, is only exposed by two contacts 6 of the both positive and negative polarity of described 3D coil.In a further embodiment, 3D loop product can possess the product feature of foregoing individual embodiments or the combination of feature.
Below be described in further detail specific embodiments of the invention.
First, according to the shape of product needed by the punch forming of 3D Curved surface metal part 1,3D Curved surface metal part 1 is selected and is conducted electricity very well, and resistivity is little, the metal material of rapid heat dissipation.Preferred silver, brass, phosphor-copper, beryllium copper etc.3D Curved surface metal part 1 adopts impact style, comprises sawing sheet, stretching, the process such as die-cut.Preferably, 3D Curved surface metal part 1 length and width all >=160mm.Before the punch forming of 3D Curved surface metal part 1, preferably Nickel Plating Treatment is done to material.
The moulding 3 of injection mo(u)lding and described 3D Curved surface metal part 1 mating shapes, the edge of moulding 3 is formed with 3 locating buttons 4 of circumferentially uniform intervals distribution.The material of moulding 3 can be any one plastic cement or ceramic material.Plastic cement is such as PC, ABS, PC+ABS, PC+20%GF etc.The thickness of moulding 3 be 1.0mm ~ 3.0mm.During injection moulding, nozzle temperature is 270 ~ 300 DEG C, and mold temperature is 60 ~ 100 DEG C, and injection pressure is 50 ~ 80MPa.
3D Curved surface metal part 1 good for the punching press mode of gum or some glue silane coupling agent and moulding 3 are bonded together.
Then, can moulding 3 be fixed on tool, adopt the techniques such as CNC, radium carving and/or finishing impression that 3D Curved surface metal part 1 is processed coil 5.The width of coil 5 and coil-span can set as required.Preferably, the wide 1.5mm ~ 6.0mm of coil, live width 0.5 ~ 3.0mm, to obtain the irritability that larger inductance value is become reconciled by preferably size.
Two contacts 6 are formed in the position of coil 5 close head, tail.Can relevant position welding on two metal contact 6.Two contacts 6 do pretreatment, as nickel plating or gold-plated.Do Nickel Plating Treatment, can prevent product surface with air in or water oxygen or chlorine generation chemical reaction, outward appearance can be made to keep clean beautiful, increase the service life.Do gold-plated process, chemical stability is good.
Finally structural member 2 is after treatment put into mould, in-mould injection plastic cement, 3D coil covers by plastic cement, only exposes two contacts, 6, two contacts 6 and forms both positive and negative polarity.Thus obtained 3D loop product.
After 3D loop product switches on power, formed one around magnetic field, be converted to heat energy by magnetic field energy and heat product, make electrical equipment have heating function, 3D loop product itself is not generated heat.This 3D loop product heating area is large, and heating effect is even, and save space again, make electrical equipment volume little, overall weight alleviates simultaneously.In the course of work, when the alternate magnetic force line in low coverage magnetic field is by neighbouring magnetic metal (iron, cobalt, nickel) material, the microstructure of metal can be driven, produce countless little eddy current, Metallic Microstructure itself is rubbed mutually thus self-heating, thus reaches the object of noncontact heated metal material.3D loop product is by electromagnetic induction heating, and coil itself does not generate heat because of magnetic field, and heating efficiency and efficiency are all very high.
Except being used as load coil, coil of the present invention also can be used for the purposes such as conduction, antenna receiving signal.
Above content combines concrete/preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; its embodiment that can also describe these makes some substituting or modification, and these substitute or variant all should be considered as belonging to protection scope of the present invention.
