Secondly, above-mentioned while utilizing wire wounded core, conventionally can holder be set at the two ends of magnetic core and assist coiling with fixed magnetic core, but wire is often just blocked by magnetic core and cannot be coiled into a circle at wounded core one half.Method shown in Fig. 5 and Fig. 6 A to Fig. 6 D can solve foregoing problems, wherein, the flow chart of another embodiment that Fig. 5 is coil-winding method of the present invention, Fig. 6 A to Fig. 6 D is the vertical view that utilizes the auxiliary coiling of winding mechanism.
In step S51, wire 51 is placed on magnetic core 50, make the first winding mechanism 60a and the second winding mechanism 60b clamp respectively leading portion 51a and the back segment 51b of wire 51.Specifically, wire 51 is placed on magnetic core 50 so that its front and rear sections 51a, 51b extend to respectively first and second side 50a, the 50b of magnetic core 50, and first and second side 50a, 50b that the first winding mechanism 60a and the second winding mechanism 60b are arranged at respectively to magnetic core 50 are to clamp respectively front and rear sections 51a, the 51b of wire 51.Then in step S52, make leading portion 51a that the first winding mechanism 60a clamps wire 51 towards direction 100 wounded cores 50, and make back segment 51b that the second winding mechanism 60b clamps wire 51 towards other direction 300 wounded cores 50 and the first side 50a that arrives.As shown in Figure 6A.
Then in step S53, in the time that the first winding mechanism 60a and the second winding mechanism 60b move to a predetermined thread-changing region 200, the first winding mechanism 60a decontrols the leading portion 51a of wire 51 and clamps the back segment 51b of wire 51, and while second winding mechanism 60b decontrols the back segment 51b of wire 51 and clamps the leading portion 51b of wire 51.As shown in Figure 6B.
Then in step S54, make back segment 51b that the first winding mechanism 60a clamps wire 51 towards other direction 300 wounded cores 50, the leading portion 51a that the second winding mechanism 60b clamps wire 51 is simultaneously towards direction 100 wounded cores 50.As shown in Figure 6 C.
That is to say, the leading portion 51a that clips wire 51 as the first winding mechanism 60a marches to back segment 51b that predetermined thread-changing region 200 and the second winding mechanism 60b clip wire 51 in the time that magnetic core 50 second side 50b march to predetermined thread-changing region 200 from the first side 50a of magnetic core 50, the now cross-shaped state of front and rear sections 51a, 51b of wire 51, thereby the first winding mechanism 60a and the second winding mechanism 60b need to decontrol the line segment of originally clamping and clamp line segment each other in predetermined thread-changing region 200.
In step S55, in the time that the first winding mechanism 60a and the second winding mechanism 60b move to another predetermined thread-changing region 400, the first winding mechanism 60a decontrols the back segment 51b of wire 51 and clamps the leading portion 51a of wire 51, and while second winding mechanism 60b decontrols the leading portion 51a of wire 51 and clamps the back segment 51b of wire 51.As shown in Figure 6 D.Then return to step S52, repeat implementation step S52 to S55, so that wire 51 forms the plural layer coil of at least two row on magnetic core 50.
It should be noted that, although the two ends that the first winding mechanism 60a and the second winding mechanism 60b clamp respectively wire 51 are with simultaneously by the front and rear sections wounded core 50 of wire, but see in detail the travel path of the first winding mechanism 60a and the second winding mechanism 60b, the first winding mechanism 60a is responsible for the semicircle coiling work of the first side 50a of magnetic core 50, and the second winding mechanism 60b is responsible for the semicircle coiling work of the second side 50b of magnetic core 50.
Also it should be noted that, in the shown method for winding of Fig. 5 and Fig. 6 A to Fig. 6 D, one direction 100 can be clockwise direction, other direction 300 can be counterclockwise, length is identical in fact with back segment 51b for the leading portion 51a of wire 51, and can be not overlapped when wounded core 50, and the number of plies that the leading portion 51a of wire 51 forms towards direction 100 wounded cores 50 is identical with the number of plies that the back segment 51b of wire 51 forms towards other direction 300 wounded cores 50.
In addition, refer to Fig. 7 A, Fig. 7 A is the profile that utilizes the inductance element of the coil-winding method made shown in Fig. 3 or Fig. 5.
In Fig. 7 A, the leading portion 31a of wire 31 has a1 to a6 cross section, and the back segment 31b of wire 31 has b1 to b6 cross section, and wire leading portion 31a and wire back segment 31b around opposite direction.From Fig. 7 A, first row coil 321 is formed by the overlapping wounded core 30 of the leading portion 31a by wire 31, and secondary series coil 322 is formed by the overlapping wounded core 30 of the back segment 31b by wire 31.Coil 32 shown in Fig. 7 A has three layer of two row, and it is only illustrative examples.
In addition, refer to Fig. 7 B, it is the XX tangential profile figure of Fig. 7 A.From Fig. 7 B, the leading portion 31a of wire 31 wounded core 30 toward the clockwise direction, and counterclockwise wounded core 30 of the back segment 31b of wire 31, and 31, wire around circle be concentric circles.Therefore, utilize the disclosed coil-winding method of the present invention carry out wire around, can avoid only utilizing in the past one end of wire carry out single direction around time, due to the volume of wire itself take conductor loop around space, cause the problem of arrangements of conductors inequality.
The above only illustrates the situation of a wire, but the present invention also can be applicable to the embodiment of many wires, refers to Fig. 8.Fig. 8 utilizes two wire wounded cores to form the coil of two-layer four row.
Utilize both while wounded cores 40 of Article 1 wire L1, Article 2 wire L2 can accelerate coil and form speed.Specifically, first, the leading portion L1a of Article 1 wire L1 and back segment L1b extend to respectively the phase heteropleural of magnetic core 40, and the leading portion L2a of Article 2 wire L2 and back segment L2b extend to respectively the phase heteropleural of magnetic core 40.That is to say, the cross section L2a1 of the leading portion L2a of the cross section L1a1 of the leading portion L1a of Article 1 wire L1 and Article 2 wire L2 is at homonymy, and the cross section L2b1 of the back segment L2b of the cross section L1b1 of the back segment L1b of Article 1 wire L1 and Article 2 wire L2 is at opposite side.
Then, Article 1, the leading portion L2a of the leading portion L1a of wire L1 and Article 2 wire L2 is together to be parallel to the center pillar portion 401 of mode wounded core 40 of upper end 402 of magnetic core 40, thereby cross section L1a2, L1a3 and the L1a4 of the leading portion L1a of formation Article 1 wire L1, cross section L2a2, L2a3 and the L2a4 of the leading portion L2a of Article 2 wire L2; Simultaneously the back segment L1b of Article 1 wire L1 and the back segment L2b of Article 2 wire L2 together be parallel to magnetic core 40 bottom 403 mode, with the center pillar portion 401 of the direction wounded core 40 in contrast to leading portion, thereby cross section L1b2, L1b3 and the L1b4 of the back segment L1b of formation Article 1 wire L1, cross section L2b2, L2b3 and the L2b4 of the back segment L2b of Article 2 wire L2.
Utilize like this two wires wounded core and wire back segment forms coil towards the mode of other direction wounded core to divide into wire leading portion towards a direction wounded core together, only can avoid in the past with wire one section carry out a kind of around direction around time, the puzzlement that the wire producing is entangled with.
Therefore, coil-winding method of the present invention, is applicable to inductance element, be particularly useful for the coil of inductance element the number of permutations (be the center pillar portion of magnetic core can hold around coil arrangement number) less embodiment, for example two row.Be in two rows' the embodiment of coil at columns, whether even the properties influence of the inductance element of arrangements of conductors be very large, and wherein the arrangement inequality of an alignment circle is 1/2nd impact.
In sum, coil-winding method of the present invention is wire to be placed on magnetic core so that the leading portion of wire and back segment wounded core in the opposite direction respectively, and in around time wire leading portion only overlapping and not overlapping with back segment with self, and the back segment of wire is too.Therefore, solved the problem that in the past causes arrangements of conductors inequality due to inner conductor possessive volume.In addition, while utilizing winding mechanism to carry out coil-winding, the front and rear sections of wire is often around this magnetic core half-turn, clamping the winding mechanism of this leading portion can decontrol the wire of originally clamping and remove to clamp wire each other with the winding mechanism of clamping this back segment, thereby can complete rapidly, save the time that arranges plural wires.
Should be understood that, the various embodiments described above are only for principle of the present invention and effect are described, but not for limiting the present invention.For those of ordinary skills, can be improved according to the above description or convert, and these improvement and conversion all should belong to the protection range of claims of the present invention.
