Description

Manufacturing apparatus for the induct coil

The present invention relates to a manufacturing apparatus for winding and manufacturing an inductor coil mounted on a printed circuit board.

The inductor coil is made of a conductive coil in which at least one layer is rolled into a cylindrical shape. A non-conductive enamel coating layer is formed on the outer circumferential surface of the conductive coil to prevent energization by contact with neighboring conductive coils.

The inductor coil is an electronic device whose volume is difficult to reduce due to its cylindrical shape. In order to reduce the volume of the inductor coil, an inductor coil formed of multiple layers is manufactured.

In the inductor coil made of a multilayer, two layers of conductive coils are formed successively on one layer formed by rolling the conductive coils in a cylindrical shape, and three or more layers are formed according to a selection.

The multilayer inductor coil according to the prior art has a difference in the number of coil turns of one layer and the number of turns of two layers formed thereon. This is because the conductive coils curled on both ends of the two layers easily escape from the coils of the first layer when the coil winding numbers of the first and second layers are identically stacked. Therefore, in order for the conductive coils of each layer to be stably stacked, the conductive coils should be formed with less winding number than the winding number of the base layer on which the conductive coils are wound. As a result, the number of windings of the inductor coil having a plurality of layers decreases toward the upper layer, so that the volume increases in order to manufacture the inductor coil according to a predetermined capacity.

On the other hand, the manufacturing method of the multilayer inductor coil according to the prior art has a problem that the time of movement is unclear when the conductive coil forming one layer is moved up one layer to form two layers. Therefore, since the total length of the conductive coil forming the inductor coil and the cylindrical length are different, there is a slight difference in performance for each inductor coil.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has an object of maintaining a constant performance of a mass produced inductor coil by making it possible to precisely manufacture a winding number of coils and a shape in which coils are wound.

In addition, it has the purpose of achieving integration of the inductor coil manufactured in a multilayer.

In accordance with an aspect of the present invention, a cylindrical portion in which a winding is wound is formed to protrude from one end, and includes a rotatable body portion, a rotatable press portion that can be inserted into the protruding end of the cylindrical portion, and the pressing portion is An apparatus for manufacturing an inductor coil, which is elastically mounted in an axial direction of a cylindrical portion and includes a mounting portion movable relative to the axial direction.

In addition, one end of the pressing portion may elastically support the winding wound on the outer circumferential surface of the cylindrical portion so that the winding may rise above the winding wound on the outer circumferential surface of the cylindrical portion.

In addition, the winding is supplied at a fixed position, the body portion is reciprocally sliding to a length corresponding to the width of the inductor coil along the axial direction, the mounting portion when the winding is wound around the outer peripheral surface of the cylindrical portion by the width of the inductor coil The pressing portion may be moved in the axial direction so as to contact the winding supplied.

According to an embodiment of the present invention, since the section rising from the first layer winding to the second layer winding of the inductor coil formed of the multilayer becomes constant, the width and shape of the unit inductor coil are constant, so that the performance of each inductor coil is constant. Has an effect.

In addition, since the number of windings of the multilayered windings can be manufactured the same for each layer, the degree of integration of the inductor coil is improved, thereby reducing the volume of the product.

FIG.

Hereinafter, with reference to the accompanying drawings will be described the configuration, function and operation of the apparatus for manufacturing an inductor coil, in accordance with an embodiment of the present invention. Hereinafter, in the inductor coil made of a multilayer, the winding layer is the first layer from the innermost side, and the winding wound around the outer layer is called two layers.

Referring to FIG. 1, the apparatus 10 for manufacturing an inductor coil according to an exemplary embodiment of the present invention includes a body part 1, a pressing part 2, and a mounting part 3.

The body portion 1 is formed so that the cylindrical portion 11 to which the winding constituting the inductor coil is wound protrudes from one end. In addition, the body portion 1 is rotatable using the central axis of the cylindrical portion 11 as the rotation axis. The cylindrical portion 11 protruding from one end of the body portion 1 has a smaller diameter than the body portion 1.

At this time, the stepped portion 12 of the body portion 1 forming the periphery of the cylindrical portion 11 may be provided with a holder portion 121 for holding the winding. The holder portion 121 may be a protrusion protruding in the same direction as the protrusion direction of the cylindrical portion at a position spaced apart from the cylindrical portion. The protruding length of these protrusions corresponds at least to the radius of the winding, but is shorter than the diameter of the winding.

In addition, the stepped portion 12 may be formed with a guide portion 122 formed to gradually protrude outward in the rotational direction of the body portion. The guide portion 122 may be formed of an inclined surface protruding in the axial direction of the cylindrical portion gradually around the cylindrical portion. Guide portion 122 may be formed on the opposite side of the holder portion 121, the height of the jaw 123 formed at the end of the inclined surface may be equal to or smaller than the protruding length of the protrusion.

The pressing portion 2 is formed with an insertion hole 21 into which the protruding end of the cylindrical portion can be inserted. In addition, when the cylindrical portion 11 is inserted into the insertion hole 21, the pressing portion 2 is freely rotatable in the same direction by contact with the cylindrical portion 11 that is integrally rotated with the body portion (1). .

On the other hand, the pressing portion 2 is elastically mounted in the axial direction of the cylindrical portion 11, the movable portion 3 is movable relative to the axial direction. The mounting portion 3 is formed with a long hole 31 for fixing to the sliding arm described later. The mounting portion 3 fixed to the sliding arm has a linear motion on the axis of the cylindrical portion, the pressing portion 2 can be inserted or removed in the insertion hole (21).

Referring to FIG. 2, the mounting portion 3 has a fitting hole 32 for mounting the pressing portion 2.

The pressing part 2 has an insertion hole 21 formed at one side, and the rod 22 is formed long at the other side. The bearing 24 is coupled to the front end and the rear end of the rod 22 to enable free rotation of the pressing part 2. Meanwhile, the locking means 23 is coupled to the rod 22 protruding at one end of the fitting hole 32 to prevent the pressing portion 2 from being separated from the front of the fitting hole 32, and the bearing and the rear end of the front end 32. The elastic means 25 is interposed between the bearings. Such elastic means may be a spring. Usually, the pressing portion 2 is positioned to protrude as much as possible from the fitting hole 32 by the elastic means. When one end of the pressing part 2 in which the insertion hole 21 is formed is pressed, the pressing part 2 may be moved toward the inside of the fitting hole 32. When the pressure disappears, the pressing part 2 may be moved by the restoring force of the elastic means 25. Is restored to its position.

Such a configuration may be replaced by another configuration in which the pressing portion can freely rotate in the axial direction and is elastically supported in the axial direction.

3 and 4, the winding C constituting the inductor coil is supplied perpendicular to the axial direction of the cylindrical portion 11. The supply position of this winding C is confirmed in the arrangement relationship of the supply part 7 and the body part 1 of FIG. 9 mentioned later. In addition, the height that the winding (C) is supplied is between the holder portion 121 and the outer peripheral surface of the cylindrical portion 11 of FIG.

As the body portion 1 is rotated, the winding C is caught by the holder portion 121 and starts to be wound on the outer circumferential surface of the cylindrical portion. Thereafter, the winding C is pushed in the protruding direction of the cylindrical portion 11 by the guide portion 122 formed on the stepped portion 12 of the body portion 1, and the cylindrical portion 11 is shown in FIG. 4. The first winding is started to be wound in the form of a cylinder on the outer circumferential surface of the cylindrical portion 11 while contacting the side of the winding C1 without interfering with the winding C1.

At this time, the supply portion for supplying the winding (C) is fixed in position, the body portion (1) is retracted by the thickness of the winding (winding in the left direction of Figure 4) as the winding is wound around the cylindrical portion (11) The winding supplied on a straight line can be wound in the form of a cylinder. That is, the body part 1 moves backward while rotating, and the winding which forms one layer is wound on the outer peripheral surface of the cylindrical part 11.

If the user winds up with a predetermined number of turns and then cuts the winding, an inductor coil having a single layer is manufactured.

In order to manufacture an inductor coil having a plurality of layers, the winding to be supplied must be raised above the winding of one layer. In order to raise this winding, it is necessary to move the body part which has been retreating forward and also push the supplied winding to the second floor. At this time, the function of pushing over the winding of the first layer of the winding is made by the pressing part.

5 and 6 show an operation relationship for raising the winding C supplied with the pressing portion 2 elastically pressed onto the winding C1 of the first layer. In a state where the winding is wound around the cylindrical portion 11 several times, the mounting portion is moved in contact with the winding supplied in the axial direction. As a result, the cylindrical portion 11 is inserted into the insertion hole of the pressing portion 2 and the pressing portion 2 is moved to a predetermined position.

After that, when the position of the supplied winding (C) is a reference, the pressing portion (2) is to stay in a fixed position for a while. At this time, the pressing part 2 is rotated in the same direction as the cylindrical part 11 by the inserted cylindrical part 11.

As the body portion 1 rotates forward (moves in the right direction of FIG. 5), the cylindrical portion 11 is gradually inserted into the insertion hole of the pressing portion 2, and the winding C supplied is the pressing portion ( 2). At this time, since the supplied winding C is supported by the pressing part 2, the winding C is no longer wound on the cylindrical portion 11 in parallel with the winding C1 of the first layer, and is moved over the winding C1 of the first layer. .

At this time, since the pressing portion 2 rotates together with the cylindrical portion 11, wear due to contact between the winding C supplied and one end of the pressing portion 2 is minimized. Therefore, the problem that the sheath of the winding is thinned or peeled off due to wear is eliminated.

In addition, the pressing portion 2 is elastically mounted to the mounting portion, it is possible to accurately set the position where the winding (C) supplied rides on the winding (C1) of the first layer. That is, one end of the pressing part 2 elastically supports the winding C1 wound on the outer circumferential surface of the cylindrical portion 11 so that the winding rises above the winding wound on the outer circumferential surface of the cylindrical portion 11 at a predetermined position. Will be.

In FIG. 6, one end of the pressing portion 2 is in contact with the winding C2 of the foremost contacting the outer circumferential surface of the cylindrical portion 11 (dotted line display). Thereafter, the body 1 is brought into contact with the winding C supplied as the body 1 moves forward, and the pressing part 2 is pressed to elastically move to the right side of the drawing (solid line display). At this time, the elastic movement of the pressing portion 2 is stopped in a state in which the pressing force of the pressing portion 2 is equal to the elastic force of the elastic means, and the pressing portion 2 is supplied with a constant force by the restoring force of the elastic means. (C) can be elastically supported.

At this time, the windings C1 wound in the form of a cylinder in the first layer during the elastic movement of the pressing portion 2 is pressed in the axial direction of the cylindrical portion 11 is aligned. In addition, the pressing portion 2 is fixed by pressing the foremost side of the winding (C2) forming a single layer with a constant elasticity by the elastic means at a constant pressure. Then, the trajectory of the winding raised from the first layer to the second layer begins at the fixed frontmost part, so that the trajectory of the winding rising from the first layer to the second layer is specified the same every manufacture of the inductor coil. That is, in repeated mass production of inductor coils, the windings moving from one layer to two layers are always constant so that each inductor coil has a constant performance.

Referring to FIG. 7, in order to explain the form in which the windings go up from the first floor to the second floor, the first supplied winding C3 is divided into four quarters in the clockwise direction based on the first part 110 where the winding starts to be rolled in the form of a cylinder. Part 120, three parts 130 and four parts 140 can be divided into.

If, as in the embodiment of the present invention, the pressing portion is not mounted to the mounting portion elastically in the axial direction of the cylindrical portion, in forming each inductor coil, 2 in the winding (C) of the first layer of each inductor coil 100 The winding of the winding C to the layer is arbitrarily formed, such as one portion 110 or three portions 130. In other words, the winding time is not constant as the winding goes up from the first floor to the second floor. Therefore, the total length of the windings forming the completed inductor coil or the length of the cylinder form is not constant, and thus the inductance of the inductor coil is different.

On the other hand, in the embodiment according to the present invention, when the pressing portion is elastically mounted to the mounting portion in the axial direction of the cylindrical portion, because the pressing portion of the winding of the first layer of the two layers of winding on the winding of the first layer in the state of pressing the winding to a certain pressure, At a location (eg, two parts 120), the winding of the two-layer winding can be made constant each time. As a result, the performance of the inductor coil repeatedly produced may be kept constant.

Thereafter, referring to FIG. 6 again, the body part 1 and the mounting part are moved forward together with the body part 1, and the winding moved to the second floor is wound on the outer circumferential surface of the first floor winding. On the other hand, the elastic force of the elastic means may vary depending on the thickness of the winding, the material properties according to the material.

8 shows an inductor coil 100 stacked in two layers. The winding number of the first layer and the second layer may be the same by the pressing part that elastically supports the winding. Referring back to FIG. 6, the pressing portion 2 which elastically supports the lower portion of the one-layer winding is moved forward by the gap G shown in the original position, so that the upper portion and the pressing portion 2 of the one-layer winding C4 are moved. Between one end of the winding is to form a space (S) to ride. This space S is smaller than the diameter of the winding C having a circular cross section, but sufficient space for the semicircle of the circular cross section of the winding C to rise. The windings raised to the second layer are seated in this space S, and then bent to contact the valleys formed by the neighboring windings of the first layer to form the second layer. As a result, as shown in FIG. 8, it is possible to produce the inductor coil 100 having the same number of turns of the first and second layers.

Such winding number is kept the same even when three or more layers are formed, so that the number of turns of each layer is the same. In this case, the surfaces in contact with each other may be bonded to each other so that the inductor coil formed of the multilayer may not be released by the restoring force of the winding.

As described above, the winding of the inductor coil manufactured through the apparatus for manufacturing the inductor coil according to the embodiment of the present invention does not decrease as the number of layers increases. Therefore, it occupies less volume than the conventional inductor coil.

On the other hand, the winding (C) is supplied at a fixed position, the body portion 1 is reciprocally slid to a length corresponding to the width (length of the cylinder shape described above) of the inductor coil 100 along the axial direction, When the winding is wound around the outer circumferential surface of the cylindrical portion 11 by the width of the inductor coil, the mounting portion 3 may be moved in the axial direction so as to contact the winding to which the pressing portion 2 is supplied.

Specifically, the winding is supplied at a fixed position through the supply described later. The body portion is reciprocated in one direction perpendicular to the supply direction of the winding. In addition, the mounting portion mounted on the opposite side of the body portion, that is, in the other direction perpendicular to the supply direction of the winding is reciprocated movement.

The winding in contact with the step of the body portion is wound around the cylindrical portion by the rotation and the retreat movement of the body portion to form one layer of the inductor coil. When the body portion is retracted to the length corresponding to the width of the inductor coil and the winding is wound by the width of the inductor coil required for the cylindrical portion, at this time, the mounting portion is moved in the axial direction so that the pressing portion is in contact with the foremost winding wound on the cylindrical portion. . Thereafter, as described above, the newly supplied winding is rotated together with the body portion and the mounting portion, and is wound around the outer side of the first layer of the winding as it moves forward.

In this case, when the winding forming the first layer is wound, the winding is not pressurized by the pressing portion, so that the winding and the pressing portion are not worn when forming the cylindrical shape of the first layer. That is, the contact of the windings by the pressing portion is limited to the time when going up from the first layer to the second layer, it is possible to minimize the breakage, deformation, etc. of the thin winding.

9 to 11 are schematic plan views of an apparatus for manufacturing an inductor coil according to an embodiment of the present invention.

Rotation and reciprocating sliding movement of the body portion 1 and sliding movement of the mounting portion 3 described above are made through automated mechanical equipment, or the first operating portion 5, the second operating portion 6, which will be described later, It can be made through the power unit (4).

The apparatus 10 for manufacturing an inductor coil according to an exemplary embodiment of the present invention includes a first operating part 5 which rotates the body portion 1 in the rotational axis and slides on a straight line parallel to the axial direction. ), A second operating part 6 for moving one end of the pressing part 2 to a position at an interval corresponding to the width of the inductor coil when the winding is wound around the cylindrical part 11, and the first operating part 5. ) May further include a power unit 4 for transmitting power to the second operating unit 6, and a supply unit 7 providing the winding C.

First, the power unit 4 transmits the rotational force of the motor 41 to the first operating unit 5 and the second operating unit (6). One of the features of the present invention is to allow the above-described operation to be made using a single motor.

Specifically, the power unit 4 is a motor 41 for providing a rotational force, the first gear 42 to rotate by receiving the rotational force of the motor 41, and the rotation to the first gear 42 reciprocating linear motion The crank part 43 to switch to is included.

At this time, the crank portion 43 is a link arm 431 eccentrically hinged to the outer side of the first gear 42, a rod bundle 432 slidably coupled to the outer peripheral surface of the link arm 431, and the rail The slider 434 includes a slider 434 which linearly moves on the 433 and the rod bundle 432 is rotatably coupled.

The first actuating part 5 is fixed to one end of the crank part 43 and moves in the same direction as the rack gear 51 and the rack gear 51 which linearly move in the longitudinal direction thereof, and the inclination directions are opposite to each other. The second cam (52) having an in operation surface, the body portion (1) coupled to the body portion having the same axis as the cylindrical portion (11) rotation axis 53, the linear motion of the lex gear 51 Gear portion 54 to allow the axial movement of the body portion rotation shaft 53 while rotating the body portion rotation shaft 53 by switching to a rotary motion, and one end 551 of the second cam 52 Supported on the operating surface, the other end 552 is hinged to the body portion rotation shaft 53 to restrict the axial movement while allowing rotation of the body portion rotation shaft 53, the central portion 553 is one end and the other end It includes a seesaw link 55 that is a rotation axis.

At this time, the central portion 553 of the seesaw link 55 is configured to elastically press the one end 551 toward the operating surface of the second cam 52 by a spring (not shown).

In addition, the first operating part 5 is installed to be elastically rotated by a third cam 561 coupled to the rotation shaft 421 of the first gear 42, one end of which is the seesaw link 55. Pressing the other end 552 of the body portion rotating shaft 53 and the body portion (1) retreating relative to the winding (C) relative to, one end of the seesaw link 55 is the second cam (52) A recess 56 may be further included to separate the operating surface of the recess 56.

Meanwhile, a first cam 61 connected to the rotating shaft 421 of the first gear 42 and the bevel gear 422, and one end of the second operating part 6 are connected to the first cam 61. Resilient contact is reciprocating sliding movement, the other end includes a sliding arm 62 is coupled to the mounting portion (3).

On the other hand, the supply unit 7 is a feeder for continuously supplying the windings at a constant cycle. At this time, the cycle and the supply speed of the supply of the winding is determined by the user's setting in consideration of the operation time of the body portion and the mounting portion to be described later.

8 shows the starting point of operation of the manufacturing apparatus of the inductor coil.

The first gear 42 is rotated by the rotation of the motor 41, and the rack gear 51 and the second cam 52 are lower by the crank part 43 coupled to the first gear 42. Is sliding into. The body part rotation shaft 53 is rotated by the gear part 54 in which the input shaft is gear-coupled to the lex gear 51. At this time, the gear unit 54 may be formed of a gear box that varies the rotation speed.

At the same time, the seesaw link 55 supported by the operating surface of the second cam 52 rotates in the clockwise direction and moves the body part rotating shaft 53 connected to the other end 552 of the seesaw link 55 to the left.

By the rotation of the body portion rotating shaft 53 and the movement in the left direction, the body portion 1 coupled to the body portion rotating shaft 53 is also gradually moved to the left while rotating, winding the winding (C) to the cylindrical portion do.

Meanwhile, the first cam 61 connected to the rotating shaft of the first gear 42 and the bevel gear 422 is rotated by the operation of the motor 41. Initially, since one end of the sliding arm 62 is in contact with the short diameter portion of the first cam 61, the mounting part 3 stays at a position spaced apart from the winding C.

On the other hand, Figure 10 shows when the first layer of the inductor coil manufacturing is completed, and the second layer of manufacturing is started in succession.

The first gear 42 is in a state of continuously rotating by the motor 41. The crank part 43 further lowers the leggear 51 and the second cam 52 to the lower end of the drawing. At this time, the body part rotation shaft 53 is still being rotated in the same direction as in FIG. 9 by the movement of the gear gear 51 and the gear part 54.

When one end 551 of the seesaw link 55 reaches the maximum protruding portion of the operating surface of the second cam 52, it is connected to the rotating shaft 421 of the first gear 42 and the bevel gear 422 to be rotated. One end of the sliding arm 62 is in contact with the long diameter portion of the first cam 61. As a result, the sliding arm 62 and the mounting part 3 are moved to the right side, and the pressing part 2 is in contact with the winding C wound on the cylindrical part 11. This causes the winding to rise from one layer to two layers as described above.

The seesaw link 55 is slowly rotated counterclockwise in the drawing while riding the inclined working surface passing down the vertex portion of the second cam 52. As a result, the body rotating shaft 53 and the body 1 are started to move to the right. In addition, the sliding arm 62 and the mounting portion 3 are also in contact with the reduced diameter portion of the first cam 61 and is moved to the right side as the body portion 1. At the same time, two layers of windings are made.

On the other hand, Figure 10 is a process of returning the body portion and the mounting portion to the original position after the manufacture of the inductor coil is finished.

The first gear portion 54 is in a state of continuously rotating by the motor 41. By the crank part 43, the lex gear 51 and the second cam 52 are moved to the upper end of the figure and returned to the final original position.

Meanwhile, the locking jaw 562 of the recess 56 is pushed to the right by the third cam 561 coupled to the rotation shaft of the first gear 42. As a result, the recess 56 is rotated counterclockwise. The other end 552 and the body rotating shaft 53 of the seesaw link 55 is largely moved to the right by the recess 56. As a result, the cylindrical part is pulled out to the right at the center of the manufactured inductor coil 100 connected to the winding drawn out from the supply part.

In addition, by the rotation of the first gear 42, the first cam 61 is moved to a short diameter portion and returned to its original position, spaced apart from the winding C.

Thereafter, the winding C connected to the inductor coil is cut by the cutting means 8 to manufacture the inductor coil.

Since a new winding is supplied again by the supply unit, it is possible to produce a continuous inductor coil by repeating the above-described operation process.
