Description

Inductor, coil assembly and device for manufacturing inductor

Technical Field

The utility model relates to the technical field of machinery, in particular to an inductor, a coil assembly and a device for manufacturing the inductor.

Background

Prior art inductors are typically made by the following method (taking toroidal cores as an example): and sleeving the wound coil on the semi-ring magnetic core, and assembling and splicing the magnetic core. On one hand, the half-ring magnetic core is usually cut from the whole ring magnetic core, and there may be an error in the cutting process, resulting in an air gap in the spliced ring magnetic core, and the leakage flux generated by the air gap may bring extra loss. The magnetic core may be worn during the cutting process, resulting in a reduced volume of the magnetic core and reduced performance. On the other hand, in order to ensure that the two half-ring magnetic cores are firmly spliced, a stainless steel band with insulation wrapping is generally adopted to carry out whole-ring binding along the outer ring of the magnetic ring, and the procedure can be operated only by hands, so that the efficiency is low, and the material cost and the labor cost are increased.

Although the inductor constructed by surrounding a magnetic core (not only a ring-shaped magnetic core) by using a splicing coil exists in the prior art, the inductor still has the problems that the mechanical assembly is not easy in the assembly production process, the assembly efficiency is low and the like.

In view of the foregoing, an inductor, a coil assembly and an apparatus for manufacturing the inductor are provided, which can overcome at least one of the disadvantages of the prior art.

Unless otherwise indicated, the directional terms described herein are generally in accordance with conventional directions as understood by those skilled in the art.

As shown in fig. 1-8, the present invention provides an inductor 1 according to one aspect of the present invention. Wherein the inductor 1 comprises a magnetic core 10 and a coil assembly 12. The magnetic core 10 is advantageously configured as an un-assembled complete toroid structure, i.e., the toroidal core 10 is a complete structure rather than a remachined and spliced structure. Alternatively, the magnetic core 10 may alternatively be rectangular columnar, block-shaped, or the like, for example, configured as a chip inductor. For inductors using toroidal cores, the prior art generally used inductors 1 manufactured using a technique of cutting cores and then splicing them into a ring, and such cores resulted in reduced performance and increased cost, as mentioned in the background. The prior art use of such toroidal cores is primarily limited by the existing coil configurations. As also mentioned in the background, with chip inductors (which typically employ rectangular cylindrical, block-shaped magnetic cores), such inductors often suffer from certain drawbacks in coil structure and arrangement that result in an inductor that is not ideally assembled.

Referring to fig. 2, the coil assembly 12 includes first and second component groups that are split toward each other to form a multi-turn coil and enclose the magnetic core 10 inside. Wherein the first member set includes a plurality of first members 120 evenly distributed along a center, the second member set includes a plurality of second members 122 evenly distributed in the same manner along the same center in sequence spaced from the plurality of first members 120, and the first members 120 and the second members 122 are generally mounted to the magnetic core 10 from opposite sides of the magnetic core 10 with respect to the magnetic core 10. The first member 120 and the second member 122 may also be referred to as an "upper member" and a "lower member", respectively. The starting end of each first member 120 has a deflection portion adjacent to the end of the second member 122 at a forward spaced position to form a coil of one turn, and at least the end of each first member 120 has a deflection portion adjacent to the starting end of the second member 122 at a rearward spaced position to form coils of adjacent turns in sequence.

Furthermore, the end of each second member 122 may also have a deflection portion approaching the starting end of the first member 120 at a later interval position so as to be connected to the corresponding first member 120 to form a coil, and the starting end of each second member 122 may also have a deflection portion approaching the end of the second member 122 at a previous interval position so as to be connected to the coils of the adjacent coils in sequence. The initial and terminal ends mentioned above refer to the two free ends each of the members has. The term "spaced position" may be understood as a position offset from the approach of the member itself towards an adjacent member. The terms "front" and "rear" are used with reference to the left and right as shown in FIG. 2.

In the illustrated embodiment, the first member 120 and the second member 122 may be configured as an "L" -shaped sheet-like (flat) structure, with the first member 120 in an inverted L-shaped arrangement and the second member 122 in an L-shaped arrangement in an actual installed condition. It can be seen that the first and

second members

120, 122 are each configured as a sheet having a horizontal portion and a vertical portion. In order to constitute the first member 120 and the second member 122 into a substantially rectangular coil, the horizontal portion of the first member 120 is engaged with the vertical portion of the adjacent second member 122, and the vertical portion of the first member 120 is engaged with the horizontal portion of the other adjacent second member 122, so that one first member 120 is connected to its adjacent two second members 122. The first member 120 and the second member 122 are provided at respective free ends with offset portions configured to be bent toward members to be joined to reduce a distance of free ends of the adjacent members, so that when the first member 120 is joined to the second member 122, the two can be joined with the offset portions in a state where the second member equally divides a space between the two adjacent first members 120.

When the magnetic core has an arc segment, the center may be a curvature center of the arc segment, and when the magnetic core is a complete annular magnetic core, the center may be a center of a circle. Taking the magnetic core in fig. 2 as an example of a closed circular ring shape, the plurality of first members 120 are uniformly distributed around the center of the circular arc segment at an equal central angle, the plurality of second members 122 are also uniformly distributed around the center of the circular arc segment at an equal central angle, and each second member 122 is sequentially spaced from the first members 120 at an equal central angle with respect to the two adjacent first members 120. That is, the first member 120 and the second member 122 are joined by the offset portion provided at each free end, which is configured to be bent toward the members to be joined to reduce the distance of the free ends of the adjacent members, so that when the first member 120 is joined to the second member 122, the two members can be joined by the offset portion in a state where the second member equally divides the interval between the two adjacent first members 120.

Taking the toroidal core as an example, according to the connection method of the first member 120 and the second member 122, the first member 120 and the second member 122 are sequentially contacted to define the toroidal core in a space formed therebetween, thereby forming a complete coil surrounding the toroidal core. The first member 120 and the second member 122 are joined into a substantially rectangular combined coil which surrounds the annular magnetic core in the radial direction thereof and is equally distributed in the circumferential direction thereof.

After the first and

second members

120, 122 are positionally fixed relative to each other in a generally rectangular shape, the first and

second members

120, 122 can be considered to be disposed and engaged relative to each other in a generally rotationally symmetric fashion. By "rotational symmetry" is meant herein the situation where either of the connected first member 120 or second member 122, after rotation through 90 °, substantially coincides with the other member in the plane of the coil assembly.

When the magnetic core 10 has a long straight section, the center is an axis of the long straight section, the plurality of first members 120 are uniformly distributed along the axis of the long straight section at equal intervals and perpendicular to the axis, the plurality of second members 122 are also uniformly distributed along the axis of the long straight section at equal intervals and perpendicular to the axis, and each second member 122 is sequentially spaced from the first member 120 at intervals of two adjacent first members 120.

Taking a patch inductor employing, for example, a rectangular block-shaped magnetic core as an example, the first member 120 and the second member 122 are connected in series to define the magnetic core in the space formed by the first member 120 and the second member 122, thereby forming a complete coil surrounding the magnetic core. The first member 120 and the second member 122 are joined into a substantially rectangular combined coil that surrounds the magnetic core in the axial direction thereof and is equally distributed in the circumferential direction thereof. The first member 120 and the second member 122 are configured by the offset portions provided at the respective free ends to form a case where the second member equally divides the interval of two adjacent first members 120 when the two are joined. The engagement of the first member 120 and the second member 122 with each other is achieved by the following structure.

Referring to fig. 2, the horizontal and vertical portions of the first member 120 are formed at free ends thereof with first and second engagement ends 120a and 120b, respectively. Among them, the second engaging end 120b may be formed as a first deflected portion that is a structure that protrudes laterally from the vertical portion of the first member 120, is folded back to the vertical direction, and continues to extend away from the vertical portion thereof. It is contemplated that the first engagement end 120a may also be formed with a corresponding offset. However, for the ring-shaped magnetic core, it is preferable that the first member 120 is provided with the offset portion only at the free end of the vertical portion thereof (i.e., the second joining end 120b), and the second member 122 is provided with the offset portions at both the free ends of the vertical portion and the horizontal portion thereof. The purpose of this arrangement is to take into account the significant difference in circumference between the inner and outer rings of the toroidal core, with the inner adjacent members being closer and the outer adjacent members being further apart. The horizontal and vertical portions of the second member 122 are formed with first and second mating ends 122a and 122b, respectively, at free ends thereof. Wherein the first mating end 122a is formed as a second deflected portion that is a structure that projects laterally from the vertical portion of the second member 122, is folded back vertically, and continues to extend away from the vertical portion. The second mating end 122b is formed as a third deflected portion that projects laterally from the horizontal portion of the second member 122, is folded back into the horizontal direction, and continues to extend away from the horizontal portion.

Each of the above-mentioned deflections is substantially in the direction of its extent relative to the component in which it is located

The shape of the bent part can be optionally a right angle, the design not only can achieve the effect that each turn of coil is basically vertically arranged relative to the circumferential direction of the annular magnetic core 10, but also can ensure the effect that the horizontal parts and the vertical parts of the first member 120 and the second member 122 which are combined equally divide the distance between two adjacent single turns of coil, and the corresponding members are simple to manufacture, the connection of the first member and the second member is simple and convenient, the cost is low, and the matching installation of the two members is more convenient and quicker.

The alternating connection in sequence between a first member 120 and its adjacent second member 122 is achieved by the aforementioned corresponding mating engagement between the first mating end 120a and the first mating end 122a, and the second mating end 120b and the second mating end 122 b. When the first and

second members

120 and 122 of the "L" shape are joined, as shown in fig. 2 and 5 for an example of a toroidal core, the first joining end 120a and the second mating end 122a of the two are joined at the inner side of the toroidal core (hereinafter may be simply referred to as an inner ring or an inner ring), and the second joining end 120b and the second mating end 122b are joined at the outer side of the toroidal core (hereinafter may be simply referred to as an outer ring or an outer ring). Wherein "inside of the annular magnetic core" and "outside of the annular magnetic core" refer to the inside of the annular magnetic core 10 (inner diameter range) and the outside of the annular magnetic core (outer diameter range), respectively.

Alternatively, in the circumferential direction of the annular magnetic core, the coil assembly 12 arranged in the ring of the annular magnetic core is configured as described above as a flat coil, and the width of the flat coil located in the ring is smaller than the width of the flat coil arranged outside the ring of the annular magnetic core. That is, as shown in fig. 1, since the inner ring of the annular magnetic core is smaller than the outer ring, in order to be able to sufficiently utilize the inner ring space of the annular magnetic core so as to arrange the flat coil 12 as much as possible, after the first member 120 and the second member 122 are sequentially joined to form a full turn, the thickness of the flat coil 12 located inside the annular magnetic core ring may preferably be smaller than the thickness thereof located outside the annular magnetic core ring.

The cross section of the flat coil 12 mentioned above can optionally be configured as a rectangle, as a trapezoid or as a shape based on the concave or convex shape of the two sides of the trapezoid. Since the inner ring of the annular magnetic core is smaller than the outer ring, in order to make full use of the inner ring space of the annular magnetic core so as to arrange the flat coil 12 as much as possible, the cross-sectional shape of the flat coil 12 may be appropriately adjusted, for example, when the section of the flat coil 12 is trapezoidal, the trapezoidal upper base (shorter) of the flat coil 12 may be arranged on the side of the inner ring of the magnetic core away from the annular magnetic core, and the trapezoidal lower base (longer) may be arranged on the side of the inner ring of the magnetic core toward the annular magnetic core.

Further, the shapes of the first member 120 and the second member 122 described above are not limited to the "L" shape. Such a structural design is mainly to facilitate the application of the later-mentioned device for manufacturing the inductor 1, mainly in that the device provides convenience of the first member 120 and the second member 122 from the upper and lower sides in the axial direction of the toroidal core.

It is also conceivable for the person skilled in the art that the first and second component parts are separate two parts, wherein the first part can be a rectangular structure with one open side and the second component part is substantially in the form of a straight structure, or that the first and second component parts are constructed in one piece, wherein the first component part is open on the side facing the magnetic core 10 and the second component part in the form of a straight is pivotally connected to the first component part. When it is desired to mount the coil relative to the toroidal core, in the first case the first member may approach the toroidal core from axially above the toroidal core and the second member may approach the toroidal core from axially below the toroidal core, and after both have received the cores within their jointly defined space, the two members may be welded together at their respective joining and mating ends using means as hereinafter referred to. In the second case, the first component, to which the second component is pivoted, is brought close to the annular core from the axially upper side thereof in a manner open on one side, after which the non-pivoted ends are welded together by means of the devices mentioned below, and the pivoted ends can also be further reinforced as required. After the splicing is finished, the first member and the second member are jointed through the deflection parts arranged at the free ends of the first member and the second member, so that the second member equally divides the space between the two adjacent first members.

For the chip inductor, the mounting method and the general steps thereof can refer to the mounting method of the second member and the corresponding first member in the straight line shape. In a chip inductor, the core 10 is generally, for example, a rectangular column or block, and the first and second members joined around the core are generally free from a difference in the number of arrangement of the offset portions of the two members caused by a difference in the inner and outer circumferences of the ring in the example of the ring-shaped core.

According to yet another aspect of the present invention, there is provided an apparatus for manufacturing the aforementioned inductor. Referring to fig. 4 to 8, the assembly of the inductor and the devices in the respective steps of manufacturing the inductor is shown.

The apparatus 2 includes a support mechanism 20, a drive mechanism 22, an automatic feed mechanism, and a connection mechanism 28. Wherein the auto-feed mechanism is used to provide the first and second components required to manufacture the inductor, and therefore the auto-feed mechanism comprises a first auto-feed mechanism 24 and a second auto-feed mechanism 26 that feed the two components separately.

The support mechanism 20 is used to support the toroidal core so that it rests substantially smoothly on the support mechanism 20 in preparation for the routing installation of the coils. The driving mechanism 22 is electrically connected to the supporting mechanism 20 to provide the supporting mechanism 20 with a rotational power, so that after one coil turn is mounted, the supporting mechanism 20 is rotated moderately to rotate the toroidal core to a position of a next coil turn to be mounted. The first automatic feed mechanism 24 and the second automatic feed mechanism 26 are arranged on the upper and lower sides in the axial direction thereof with respect to the annular magnetic core, respectively, to feed the first member and the second member, respectively.

For one embodiment of the inductor 1 provided by the present invention, when the first member 120 and the second member 122 may be respectively configured in an "L" shape, or the first member 120 and the second member 122 are respectively configured in a rectangle and a "one" shape with one side open, the first automatic feeding mechanism 24 and the second automatic feeding mechanism 26 respectively carry the first member 120 and the second member 122 to route the first member 120 and the second member 122 relative to the toroidal core from up and down two directions along the axial direction of the toroidal core.

Alternatively, when the first member 120 and the second member 122 are respectively rectangular and in-line with one side open and both are joined at the ends to configure a pivotally connected one-piece, the first automatic feed mechanism 24 supplies the one-piece (which is the first member 120 pivotally connected with the second member 122) to the toroidal core from above the toroidal core so that the first member 120 surrounds the toroidal core while the second member 122 hangs down freely, and the second automatic feed mechanism 26 acts on the second member 122 to pivot it so that the other end thereof is joined to the first member 120. The connection mechanism 28 is used to weld the above-mentioned first and

second members

120, 122 in various forms of ganged mating to one another at their respective mating and joining ends to form a complete coil of wire running around the toroidal core in firm engagement with one another. In particular, the connecting mechanism 28 may be configured as a soldering tweezers.

In particular embodiments, both the first and second

automatic feed mechanisms

24, 26 may be configured as flat feed cassettes capable of carrying respective components. Alternatively, the first automatic feed mechanism 24 and the second automatic feed mechanism 26 may also be configured as a jig so as to carry the respective components. Of course, other configurations of the automatic feed mechanism capable of carrying the respective component to transport it to the position to be mounted are also conceivable by the person skilled in the art, possibly also combinations of these configurations, without departing from the scope of protection of the present invention.

The inductor and the inductor device manufactured by the inductor overcome the defects of magnetic flux leakage, unstable inductance, poor structural stability of the magnetic core and the like caused by the adoption of the assembled (spliced) magnetic core in the prior art. Meanwhile, the assembly of the coil and the magnetic core are easier to mechanize by adopting the splicing type coil, so that the assembly efficiency is improved, and the inductor structure has better stability, namely, lower coil resistance and electrical loss.
