Description

The present disclosure relates to a device for winding a coil around a bobbin using a guide, and more particularly to a winding device capable of guiding the winding position of the coil to increase the precision of the winding.

Recently, the spread of electric vehicles has been accelerating with the development of secondary battery technology and government subsidy policies. As a result, there is an increasing demand for miniaturization, weight reduction, and high output of drive motors mounted on electric vehicles. To achieve this, various methods in which the coil can be wound are being studied.

Among various methods of winding a coil, there is a method of winding using a square coil instead of a circular coil. In the case of a circular coil, due to its shape, gaps can occur no matter how closely the coil is wound, whereas in the case of a quadrangular coil, it is structurally wound in multiple layers on the bobbin without gaps. Is possible. However, when the quadrangular coil is wound at high speed without a precise guide by the same method as the circular coil, problems such as coil isolation and pattern collapse may occur.

An upper slip ring configured to provide electrical connectivity, a lower rotating section that is rotatable about the same axis of rotation as the upper rotating section, and at least one lower guiding system, and a control section. It can include a lower slip ring configured to provide an electrical connection to and from one lower guide system. Here, the upper rotation drive unit and the lower rotation drive unit are controlled so that the upper rotation unit and the lower rotation unit rotate in synchronization, and the control unit rotates in synchronization with the upper rotation unit and the lower rotation unit. At least one of the upper guide system and at least one lower guide system can be controlled so as to guide the position of the metal wire wound around the bobbin fixed between the upper rotation part and the lower rotation part. .. On the other hand, the metal wire can have a rectangular cross section.

According to various embodiments of the present disclosure, the metal wire can be wound with high precision and high speed by guiding the metal wire with the upper guide and the lower guide. Further, by providing the winding device with a slip ring, twisting or cutting of the electric wire can be prevented even when the guide guides the winding of the metal wire while rotating with the bobbin. The use of the slip ring makes it possible to simplify the structure of the winding device and reduce the weight of the winding device as compared with the one having a general mechanical structure. The effects of the present disclosure are not limited thereto, and other effects not mentioned should be clearly understood by those skilled in the art from the claims.

For example, the upper rotation drive unit 172 can transmit rotational power to the upper rotation unit 112 by using a timing pulley (not shown) or the like. The upper rotating portion 112 may include a first upper guide system 132, a second upper guide system 134, and a fixing portion 142 that is movable in the vertical direction (z-axis direction) for fixing the bobbin 190. can. The first upper guide system 132 and the second upper guide system 134 have an x-axis and a z-axis based on a control signal from a control unit (not shown) transmitted via an upper slip ring (not shown). It can be driven in the direction of, and the position of the metal wire wound around the bobbin 190 can be guided.

The lower winding portion 120 can include a lower rotating portion 122, a lower rotating drive portion 174 and a lower housing 164, and the lower housing 164 can include a lower slip ring (not shown). The lower rotation unit 122 can rotate as a whole about the rotation shaft 180 by driving the lower rotation drive unit 174. For example, the lower rotation drive unit 174 can transmit rotational power to the lower rotation unit 122 by using a timing pulley (not shown) or the like.

The lower rotating portion 122 can include a first lower guide system 136, a second lower guide system 138, and a stage 140 for anchoring and fixing the bobbin 190. The first lower guide system 136 and the second lower guide system 138 have an x-axis and a z-axis based on a control signal from a control unit (not shown) transmitted via a lower slip ring (not shown). It can be driven in the direction of, and the position of the metal wire wound around the bobbin 190 can be guided.

The upper winding portion 110 and the lower winding portion 120 can be firmly fixedly supported by the support frame 150. The upper rotation drive unit 172 and the lower rotation drive unit 174 can rotate the upper rotation unit 112 and the lower rotation unit 122 based on a control signal from the control unit (not shown). Here, the upper rotation unit 112 and the lower rotation unit 122 can be synchronized by the control unit and rotate in the same direction and at the same speed. The detailed configuration of the upper winding portion 110 and the lower winding portion 120 will be described later with reference to FIGS. 2 and 3.

In order to wind the metal wire around the bobbin 190, the bobbin 190 can be first fixed on the stage 140. Here, the metal wire can have a rectangular cross section. After that, the bobbin 190 is fixed to the stage 140 using a clamp (not shown) or the like, and the fixed portion 142 is moved downward along the z-axis to firmly move the bobbin 190 between the stage 140 and the fixed portion 142. Can be fixed.

When the upper rotating portion 112 and the lower rotating portion 122 rotate in synchronization with each other, the bobbin 190 arranged between the stage 140 and the fixed portion 142 also rotates, and the metal wire supplied from the metal wire supply portion 160 is the bobbin 190. Wound to. The position where the metal wire is wound around the bobbin 190 can be controlled by moving the metal wire supply unit 160 in the z-axis direction. Here, the moving direction of the metal wire rod supply unit 160 is not limited to the z-axis direction, and can move not only in the z-axis direction but also in the x-axis and y-axis directions.

The wire can be wound while precisely guiding the position where the wire is wound on the bobbin 190. Although FIG. 1 shows two upper guide systems and two lower guide systems, the number of upper guide systems and lower guide systems can be changed as necessary without limitation.

Further, the control unit can control the rotation speeds of the upper rotation unit 112 and the lower rotation unit 122 based on whether or not at least one guide system intervenes. For example, if the guide unit of at least one guide system intervenes to wind the metal wire supplied from the metal wire supply unit 160 in a desired pattern, the control unit will be the upper rotation unit 112 and the lower rotation unit 122. The rotation speed can be reduced to the same. This allows the guide system to guide the metal wire more stably and wind it with high accuracy.

FIG. 2 is a diagram showing a detailed configuration of the upper winding portion 110 according to the embodiment of the present disclosure. The upper winding portion 110 can include an upper rotating portion 112, an upper rotating drive portion 172 and an upper slip ring (not shown), and the upper slip ring can be arranged in the upper housing 162. The upper rotating portion 112 can include a first upper guide portion 210, a second upper guide portion 220, and a fixing portion 142 for fixing the bobbin.

The fixed portion 142 is configured to be movable in the vertical direction (z-axis direction), and when the metal wire is wound around the bobbin, the fixed portion 142 moves downward along the z-axis and the lower winding portion. By fixing the bobbin coupled to, it is possible to prevent the bobbin from being separated from the winding device by centrifugal force during winding. For example, the fixation portion 142 can consist of a coupling portion configured to be coupled to the bobbin and a load that allows the coupling portion to move vertically. Here, the joint can have a shape corresponding to the top of the bobbin, as shown in the figure.

The upper rotation unit 112 can rotate as a whole about the rotation shaft 180 by driving the upper rotation drive unit 172. Therefore, the bobbin fixed by the fixing portion 142 also rotates, and the metal wire supplied from the metal wire supply portion can be wound around the bobbin. At this time, the first upper guide portion 210 and the second upper guide portion 220 can be operated based on the control signal transmitted from the control unit (not shown), and the metal wire rod wound while rotating with the bobbin. The position of can be guided.

For this purpose, the upper rotating portion 112 has a first upper x-axis drive portion 212 for moving the first upper guide portion 210 to the x-axis and a first upper z-axis drive unit for moving the first upper guide portion 210 to the z-axis. It may further include 214, a second upper x-axis drive unit 222 for moving the second upper guide unit 220 to the x-axis, and a second upper z-axis drive unit 224 for moving the second upper guide unit 220 to the z-axis. can. For example, the first upper guide portion 210 and the second upper guide portion 220 are arranged to face each other on both side surfaces of the fixing portion 142, and can be controlled so as to guide the position where the metal wire is wound around the bobbin. Although two upper guide portions are shown in FIG. 2, the present invention is not limited to this and can be changed as needed.

The first upper x-axis drive unit 212 and the first upper z-axis drive unit 214 may move the first upper guide unit 210 in the x-axis and z-axis directions based on the control signal from the control unit. can. Similarly, the second upper x-axis drive unit 222 and the second upper z-axis drive unit 224 move the second upper guide unit 220 in the x-axis and z-axis directions based on the control signal from the control unit. Can be made to. The control unit and the first upper x-axis drive unit 212, the first upper z-axis drive unit 214, the second upper x-axis drive unit 222, and the second upper z-axis drive unit 224 transmit control signals. Can be electrically connected to do so.

When the control unit and the x-axis and z-axis drive units 212, 214, 222, 224 are connected by electric wires, when the upper rotation drive unit 172 rotates the upper rotation unit 112, there is a problem of twisting or cutting of the electric wires. Can occur. In order to solve such a problem, an upper slip ring (not shown) can be arranged on the rotating shaft 180 in the upper housing 162. The upper slip ring does not twist or cut the electric wire between the control unit and the x-axis and z-axis drive units 212, 214, 222, 224 even when the upper rotation unit 112 rotates, and at the same time, it is electrical. By maintaining the connection, the control signal can be transmitted to the x-axis and z-axis drive units 212, 214, 222, and 224 even during rotation. The detailed configuration of the slip ring will be described later with reference to FIG.

FIG. 3 is a diagram showing a detailed configuration of the lower winding portion 120 according to the embodiment of the present disclosure. The lower winding portion 120 can include a lower rotating portion 122, a lower rotating drive portion 174 and a lower slip ring (not shown), and the lower slip ring can be arranged within the lower housing 164. The lower rotating portion 122 includes a first lower guide portion 310, a second lower guide portion 320, a stage 340 on which the bobbin is firmly fixed, and a clamp 330 for fixing the bobbin on the stage 340. Can be included. Here, the clamp 330 can be configured to be movable in the horizontal direction (x-axis direction).

The lower rotation unit 122 can be configured to rotate as a whole about the same rotation axis 180 as the upper rotation unit by driving the lower rotation drive unit 174. In one embodiment, the lower rotation unit 122 can rotate in the same direction and at the same speed in synchronization with the upper rotation unit by a control signal input to the control unit.

The bobbin around which the metal wire is wound is anchored and fixed on the stage 340, and the bobbin can be fixed to the stage 340 using a clamp 330 in order to prevent the bobbin from being separated from the stage 340. For example, as shown in the figure, the clamp 330 can have a shape corresponding to the lower part of the bobbin, and can move left and right along the x-axis depending on the size of the bobbin to firmly fix the bobbin.

Therefore, the rotation of the lower rotating portion 122 causes the bobbin fixed to the stage 340 to rotate together, so that the metal wire can be wound around the bobbin. At this time, the first lower guide portion 310 and the second lower guide portion 320 can be operated based on the control signal transmitted from the control unit (not shown), and are wound while rotating with the bobbin. The position of can be guided.

For this purpose, the lower rotating portion 122 has a first lower x-axis drive portion 312 for moving the first lower guide portion 310 to the x-axis and a first lower z-axis drive portion for moving the first lower guide portion 310 to the z-axis. It may further include a 314, a second lower x-axis drive unit 322 for moving the second lower guide unit 320 to the x-axis, and a second lower z-axis drive unit 324 for moving the second lower guide unit 320 to the z-axis. can. For example, the first lower guide portion 310 and the second lower guide portion 320 are arranged to face each other on both side surfaces of the stage 340, and can be controlled so as to guide the position where the metal wire is wound around the bobbin. Although two lower guide portions are shown in FIG. 3, the present invention is not limited to this and can be changed as needed.

The first lower x-axis drive unit 312 and the first lower z-axis drive unit 314 may move the first lower guide unit 310 in the x-axis and z-axis directions based on the control signal from the control unit. can. Similarly, the second lower x-axis drive unit 322 and the second lower z-axis drive unit 324 move the second lower guide unit 320 in the x-axis and z-axis directions based on the control signal from the control unit. Can be made to. The control unit and the first lower x-axis drive unit 312, the first lower z-axis drive unit 314, the second lower x-axis drive unit 322, and the second lower z-axis drive unit 324 transmit control signals. Can be electrically connected to do so.

When the lower rotation drive unit 174 rotates the lower rotation unit 122 when the control unit and the x-axis and z-axis drive units 312, 314, 322, and 324 are connected by electric wires, the electric wires are twisted or cut. Problems can occur. In order to solve such a problem, a lower slip ring (not shown) can be arranged on the rotating shaft 180 in the lower housing 164. The lower slip ring does not cause twisting or cutting of the electric wire between the control unit and the x-axis and z-axis drive units 312, 314, 322, 324 even when the lower rotation unit 122 rotates, and at the same time, it is electrical. By maintaining the connection, the control signal can be transmitted to the x-axis and z-axis drive units 312, 314, 322, and 324 even during rotation. The detailed configuration of the slip ring will be described later with reference to FIG.

FIG. 4 is a diagram showing an example in which the bobbin 410 is fixed to the winding device according to the embodiment of the present disclosure. The bobbin 410 is firmly fixed on the stage 340, and can be firmly fixed by the fixing portion 142 of the upper rotating portion and the clamp 330 of the lower rotating portion. As described above, after the bobbin 410 is fixed on the stage 340, the clamp 330 moves in the horizontal direction (x-axis direction) to fix the lower side of the bobbin 410, and the fixing portion 142 moves downward along the z-axis. The upper side of the bobbin 410 can be fixed by moving to. Therefore, while winding the metal wire while rotating the bobbin using the winding device, it is possible to prevent the winding device and the bobbin from being separated from each other by centrifugal force or the bobbin from deviating from the normal position. By guiding the metal wire with the guide system and the lower guide system and winding the metal wire at an accurate position, a split core winding with high precision can be produced.

FIG. 5 is a diagram showing a detailed configuration of the upper slip ring 500 according to the embodiment of the present disclosure. The upper slip ring 500 can include a slip ring fixing portion 510 and a slip ring rotating portion 520, and can be arranged on a rotating shaft 180 on which the upper rotating portion and the lower rotating portion rotate. The upper slip ring 500 can electrically connect a control unit (not shown) and an upper guide unit.

Specifically, the upper slip ring 500 electrically connects the upper motor amplifier (not shown) to which the control signal is transmitted from the control unit with the x-axis drive unit and the z-axis drive unit of the upper guide unit. The control signal from the control unit is transmitted to the x-axis drive unit and the z-axis drive unit of the upper guide unit even during the rotation of the upper rotation unit. In one embodiment, one motor amplifier can be connected to four drive units. At this time, as the communication method between the control unit / motor amplifier and the x-axis drive unit and the z-axis drive unit of the upper guide unit, a serial communication method can be used instead of the pulse method. The pulse method is vulnerable to noise and may cause problems in controlling the position of the guide section when connecting to the slip ring, while the series communication method has a small number of connections and is resistant to noise, so the position of the guide section can be controlled more accurately. Because it can be done.

As shown in the figure, the slip ring fixing portion 510 is electrically connected to the control unit / motor amplifier via the first wiring 530, and the slip ring rotating portion 520 is connected to the upper guide portion via the second wiring 540. It can be electrically connected to the x-axis drive unit and the z-axis drive unit. With this configuration, when the upper rotating portion rotates while the slip ring fixing portion 510 is fixed, the slip ring rotating portion 520 rotates together with the x-axis drive unit and the z-axis drive unit of the control unit and the upper guide unit. The electrical connection between them can be maintained. FIG. 5 shows the upper slip ring 500, but the lower slip ring can also be configured with a structure similar to that of the upper slip ring 500.

FIG. 6 is a diagram showing a detailed configuration of the guide system 600 according to the embodiment of the present disclosure. As shown in the figure, the guide system 600 can include a guide unit 610, an x-axis drive unit 620, an x-axis drive unit terminal 630, a z-axis drive unit 640, and a z-axis drive unit terminal 650. In one embodiment, the wiring for controlling the x-axis drive unit 620 can be connected to the x-axis drive unit terminal 630, and the wiring for controlling the z-axis drive unit 640 can be connected to the z-axis drive unit terminal 650. The x-axis drive unit 620 and the z-axis drive unit 640 use the guide unit 610 in the x-axis direction (horizontal direction of the bobbin) and the z-axis direction (bobbin) based on the control signal transmitted from the control unit via the slip ring, respectively. Can be moved in the vertical direction).

If necessary, a y-axis drive unit for moving the guide unit 610 to the y-axis can be used, but if the width of the y-axis of the guide unit 610 is wider than the long side of the bobbin, the guide unit 610 is moved to the y-axis. Since movement is not required, the y-axis drive unit can be omitted. Therefore, one guide unit can have degrees of freedom (x-axis and z-axis) for the two axes by being controlled by the two drive units.

When the intervention of the guide unit 610 is not required, the x-axis drive unit 620 moves the guide unit 610 far from the bobbin, and when the intervention of the guide unit 610 is required, the x-axis drive unit 620 is in the position where the winding guide is required. The guide section 610 can be moved to the neighborhood of the bobbin to fit. Further, when the intervention of the guide unit 610 is required, the guide unit 610 can be moved to the z-axis so that the z-axis drive unit 640 meets the required height of the winding guide. By utilizing such a guide portion 610, the metal wire can be guided to a desired pattern and / or a desired position and wound on the bobbin.

FIG. 7 is a front view of the bobbin 700 according to an embodiment of the present disclosure. As shown in the figure, the bobbin 700 can be configured to include a winding portion 720 around which the metal wire is wound, an upper flange 710 coupled to the upper rotating portion and a lower flange 730 coupled to the lower rotating portion. Here, the upper flange 710 and the lower flange 730 can be configured to be larger than the width of the winding portion 720 in order to prevent the metal wire rod wound around the winding portion 720 from coming off. In one embodiment, the bobbin 700 can be wound in a pyramid structure in which the metal wire wound around the winding portion 720 is laminated in multiple layers from the upper flange 710 toward the lower flange 730. The width of the flange 730 can be made wider than the width of the upper flange 710.

As described above, the upper flange 710 can be configured to be fixedly coupled to the fixed portion of the upper rotating portion. For example, the upper flange 710 may have a shape corresponding to the fixed portion of the upper rotating portion, and can be firmly fixedly coupled to the fixed portion. In one embodiment, the lower flange 730 can be configured to be fixedly coupled to the stage of the lower rotating portion.

As shown in the figure, the lower flange 730 can include a recess 736 and the stage can include a convex portion having a shape corresponding to the lower flange 730. Therefore, the bobbin 700 can be fixed to the stage by fitting the concave portion 736 and the convex portion of the stage. Further, the lower flange 730 can be configured with a receiving portion 734 on the left side so as to be able to be coupled to a protruding portion of another split core around which a metal wire is wound, and is coupled to a receiving portion of another split core on the right side. A protrusion 732 configured to do so can be configured. The above-mentioned receiving portion 734 and protruding portion 732 are also used for fixing the bobbin by the clamp of the lower rotating portion, and the clamp of the lower rotating portion can have a shape corresponding to the receiving portion 734 and the protruding portion 732.

FIG. 8 is a bottom view of the bobbin 810 according to an embodiment of the present disclosure. As shown in the figure, the bobbin 810 may have a rectangular structure in which the length d2 on one side surface is longer than the length d1 on the other side surface. The guide portion 820 is arranged on the long side d2 side of the bobbin 810 so that the metal wire can be guided, and the width of the guide portion 820 can be made wider than the long side d2 of the bobbin. Therefore, when winding the metal wire around the bobbin 810, since the guide portion 820 is wider than the long side d2 of the bobbin, it is not necessary to move in the y-axis direction, and two degrees of freedom (x-axis and z-axis directions) are required. The winding of the metal wire can be guided while moving only to). The bobbin morphology shown in FIGS. 7 and 8 is only one example, and various bobbins can be used as needed. The winding device according to the present invention can wind a metal wire rod while guiding it to various types of bobbins.

FIG. 9 is a cross-sectional view of the metal wire rod 900 according to the embodiment of the present disclosure. As shown in the figure, the cross section of the metal wire 900 wound around the bobbin can be rectangular. Normally, when a bobbin is wound using a winding device, the metal wire is wound while the metal wire supply unit is moved in the z-axis direction while the winding device is rotating at high speed. It may be wound at a point above or below the position where it should be lined. This makes it difficult to produce a split core with the desired pattern. Although it has been explained that the metal wire rod supply unit is moved in the z-axis direction to wind the metal wire rod, it can be moved not only in the z-axis direction but also in the x-axis and y-axis directions.

In the case of a metal wire having a circular cross section, a groove having a shape corresponding to the circular metal wire is formed on the bobbin, so that the metal wire is naturally positive even if a slight error occurs in the winding position of the metal wire. Tends to return to position. On the other hand, as shown in the figure, in the case of the metal wire 900 having a rectangular cross section, when the metal wire is laminated in multiple layers on the bobbin, there may be many errors in the winding position of the metal wire due to the structure. Therefore, when the cross section of the metal wire is rectangular, a mechanism capable of physically guiding the winding position of the metal wire 900 is required. Such a metal wire 900 can be wound so that the long side is in contact with the winding portion of the bobbin.

FIG. 10 is a vertical cross-sectional view of the wound split core 1000 according to an embodiment of the present disclosure. In one embodiment, the split core 1000 can be wound in a pyramid form in which the metal wire rod 1030 is laminated in multiple layers from the upper flange 1010 toward the lower flange 1020. For example, as shown in the figure, the metal wire rod 1030 can be laminated in two layers, three layers, four layers and five layers and wound in a pyramid form from the upper part to the lower part of the bobbin.

FIG. 11 is a diagram showing an example in which two split cores 1110 and 1120 according to an embodiment of the present disclosure are combined. As mentioned above, the split core is configured to include protrusions and receptors and is coupled with other split cores. As shown in the figure, the protruding portion of the first split core 1110 and the receiving portion of the second split core 1120 can be fitted to bond the first split core 1110 and the second split core 1120.

FIG. 12 is a vertical sectional view of the split core stator 1200 according to the embodiment of the present disclosure. A split core in which a metal wire is wound around a bobbin is combined with a plurality of other split cores to be assembled in an annular shape, and is fixed to an annular support bracket 1210 to form a split core stator 1200. As described above, each split core can be produced without breaking the pyramid-shaped laminated structure by winding the metal wire with high precision. Therefore, when connecting a plurality of split cores to form an annular split core stator 1200, it is possible to prevent the metal wires wound around the adjacent split cores from coming into contact with each other due to the low winding quality.

FIG. 13 is a diagram showing an example of guiding the winding of a metal wire rod by using the guide portion 1330 according to the embodiment of the present disclosure. The first operation step 1310 shows a state in which the metal wire is guided by the guide portion 1330 when winding in the direction opposite to the winding direction of the layer wound immediately before. As shown in the figure, after winding the first layer of metal wire around the bobbin 1340, if the metal wire does not enter the space on the upper flange, the metal wire is wound on the next layer (second layer). You can make a line. When winding the next layer, it can be wound in the direction opposite to the winding direction of the layer wound immediately before.

At this time, if one side surface of the wound metal wire 1350 is not fixedly supported by the upper flange, the lower flange, or another metal wire already wound, the metal wire 1350 is wound by the rotational force of the winding device. It can be wound above or below the desired position. Therefore, the guide portion 1330 can be used to form a wall on the desired winding position to guide the metal wire rod 1350 so that it can be wound in the normal position. That is, the guide portion 1330 can guide the start position of the new layer in which the metal wire rod 1350 is wound on the bobbin 1340. For example, as shown in the first operating step 1310, when starting the winding of the second layer after completing the winding of the first layer, just above the position where the metal wire 1350 should be wound. A guide portion 1330 can be arranged in the metal wire rod 1350 to prevent the metal wire rod 1350 from being wound above a desired position. After that, the remaining portion of the second layer can be wound with the guide portion 1330 fixed.

The second operation step 1320 indicates a state in which the guide portion 1330 is used to guide the winding start position of the metal wire when winding the metal wire. As shown in the second operation step 1320, when the metal wire 1360 starts winding in the fourth layer, the guide portion 1330 guides the winding start position and the metal wire 1360 is above the desired position. It can be prevented from being wound with.

FIG. 14 is a diagram showing an example of guiding a winding of a metal wire rod by using the guide portions 1440, 1450, and 1460 according to other embodiments of the present disclosure. In one embodiment, the guide portions 1440, 1450, and 1460 can guide windings of a pattern (non-sequential pattern) in which the winding position of the metal wire rod changes abruptly. For example, as shown in the figure, after winding the second layer on the bobbin 1410, the metal wire can be rapidly moved from the first position 1420 to the second position 1430 and wound. When the winding is advanced without using the guide portion, the metal wire at the first position 1420 may deviate from the normal position during the winding.

Therefore, in such a case, it is desirable to guide the winding of the metal wire rod by using the guide portion. For example, the first guide portion 1440 is placed above the metal wire at the first position 1420, the second guide portion 1450 is placed below the metal wire at the first position 1420, and the first position 1420 is placed. The metal wire rod 1420 can be fixed so as not to deviate from the first position 1420. On the other hand, since the lower flange of the metal wire at the second position 1430 supports the lower surface thereof, the position of the metal wire to be wound can be guided to the second position 1430 using only one guide portion 1460. .. For example, by arranging the second upper guide portion 1460 on the upper side of the metal wire and pressing the metal wire 1430 downward, the metal wire 1430 can be guided so as to be wound around the second position 1430. In this way, by utilizing at least one guide portion, the metal wire can be guided to a desired pattern and / or a desired position and wound on the bobbin.

It is possible. It should also be understood that such modifications or alterations fall within the scope of the claims attached herein.
