Description

Coil winding device and coil winding method

The present invention relates to a coil winding device and a coil winding method, and more particularly to a coil winding device and a coil winding method capable of improving the stability of a coil inductance value.

According to the electronic and motor fields, coils of various sizes and shapes are widely used in many electronic and motor products. In general, most of the coils used in electronics and motor manufacturers are provided by winding factories. According to the requirements of wire and wire, electronic and electrical products manufacturers are winding coils of the required size and shape for electronics. Used by motor product manufacturers.

When the coil is to be wound, as shown in FIG. 1a, a conventional coil winding device first fixes the starting end wire 91 of a wire to a mandrel A, and continues to wind the wire on the mandrel A to form a coil. The winding portion R of the coil, and gradually increasing the axial height of the coil, to form a coil having only a single layer of wire in the radial direction between the leading end wire 91 of the wire and the terminating end wire 92 as shown in FIG. 1b. . Moreover, in order to improve the performance of electronic and electrical products, electronic and motor products using coils often have high-frequency power requirements, and generally can increase the number of wire layers in the radial direction of the coil; as shown in Fig. 2a, When the coil 9 having a double-layer wire is wound by the conventional coil winding device, the first layer winding portion R1 is wound on the mandrel A according to the foregoing steps, and the wire is directly on the same axis. The wire is wound again in the position, and the covering wire is wound around the first layer winding portion R1 along the axial direction of the mandrel A to form a second layer winding portion R2.

However, as shown in Fig. 2b, the aforementioned coil 9 having a double-layered wire in the radial direction, the leading end of the wire 91 is located at the innermost layer of the coil 9, and the terminating end 92 of the wire is located at the coil 9. The outermost layer, in this structure, the starting end of the innermost layer 91 is to be pulled out to electrically connect other members, so the starting end 91 will axially penetrate the inside of the coil 9, and The other end of the coil 9 is passed through, and the innermost layer of the coil 9 is traversed to the outermost layer. In this way, the starting end of the coil 9 has a height of a wire diameter at the end of the coil 9, which increases the axial height of the overall coil 9, which is becoming lighter and thinner for today's electronic and motor products. In addition, since the starting direction of the wire end 91 of the coil 9 is approximately perpendicular to the direction of the winding of the winding portions R of the coils of the coil 9, the direction of the magnetic field is also approximately vertical, so that leakage occurs. When the sense or the magnetic force lines are in contact with each other, the magnetic flux introduction is hindered, thereby affecting the stability of the inductance value when the coil 9 operates.

Moreover, referring to FIG. 3, the conventional coil winding device can be wound in the radial direction by three layers in addition to the coil 9 having the double-layer wire, and can be wound according to the winding path in FIG. The coil 9' of the above number of wire layers is adapted to meet different usage requirements, but the coil 9' always has the above disadvantages.

To this end, please refer to FIG. 4a. When another coil winding device is used to wind the coil 8, the middle portion of a wire is first fixed to a mandrel A, which is A part of the wire is wound on the mandrel A to gradually increase the axial height of the coil 8 and constitute the first layer winding portion R1 of the coil 8; at the same time, another portion of the wire is wound by an outer winding module It is wound around the first layer winding portion R1 of the coil 8 to constitute the second layer winding portion R2 of the coil 8. In this way, referring to FIG. 4b, the first end wire 81 and the second end wire 82 of the coil 8 can be located at the same axial end of the coil 8, so the first end wire 81 does not have to be The axial direction penetrates the inside of the coil 8 and can directly straddle from the inner layer of the coil 8 to the outer layer, so that the coil 8 does not cause a leakage inductance or a magnetic line to be abutted due to the direction in which the wire is routed, so the coil 8 The inductance value during operation can be relatively stable.

However, the first end wire 81 of the coil 8 still needs to straddle from the inner layer to the outer layer, so the axial end of the coil 8 still has to increase the height of one wire diameter, so that the axial height of the overall coil 8 is increased. Still can't get improvement. Further, the coil 8 wound by the other conventional coil winding device can be at most a coil 8 having a double-layered wire, and cannot be wound with a coil of three or more layers of wires, so that it is difficult to satisfy the difference. The use of the demand, the practicality is not good.

In view of this, the existing coil winding device and coil winding method are necessary to be improved.

Referring to Figures 5-7, the base speed winding module 3 further includes an abutment 33 and a A telescopic power source 34 and a sleeve 35. In detail, the abutting rod 33 has a first end 33a and a second end 33b. The abutting rod 33 extends through the second block 12 and the elastic member 23. The first end 33a of the abutting rod 33 is driven by the fly. The shaft of the fork 21 is threaded out to oppose the winding rod 31; the telescopic power source 34 is coupled to the second block 12, and the telescopic power source 34 is driven by the second end 33b of the abutting rod 33. 33 displacement.

Or, the urging rod 33 is displaced in a direction away from the winding rod 31. Moreover, the second end 33b of the abutting rod 33 can open a threading opening 332 extending from the circumferential wall of the abutting rod 33 to the end surface of the second end 33b of the abutting rod 33.

The sleeve 35 is disposed at the first end 33a of the abutting rod 33. In the embodiment, the sleeve 35 is provided with a through hole 351 and is selected to be locked by a locking member 352 (for example, a screw) through the through hole 351. The first end 33a is coupled to the end surface of the abutting rod 33 to couple the sleeve 35 to the first end 33a of the abutting rod 33; in turn, the through hole 351 is also permeable to the free end of the winding rod 31. Extending so that the sleeve 35 faces an end surface of the base speed rotary power source 32 to an end surface of the stabilizing block 311 facing the flying fork 21 (as shown in FIG. 7) for the wire The bobbin 31 is wound in the winding zone Z to form a coil (described in detail later). In other embodiments, the sleeve 35 can also be connected to a winding mold at an end thereof facing the winding rod 31. The diameter of the winding mold is larger than the diameter of the sleeve 35, and the winding rod 31 is The free end penetrates into the winding mold, so that the winding area Z is defined between the end surface of the winding mold facing the base speed rotating power source 32 and the end surface of the stabilizing block 311 facing the flying fork 21, A coil having a large diameter is wound in the winding zone Z.

Referring to FIG. 6 , when the coil winding device of the present invention is in operation, the telescopic power source 34 can control the displacement of the abutting rod 33 relative to the second block 12 to bring the abutting rod 33 toward the winding rod 31. Until the sleeve 35 is nested into the free end of the winding bar 31 by a predetermined depth, the winding zone Z is formed for winding work.

Referring to Figures 8 and 9, before starting the winding, one end of a wire L is inserted into the wire passage 214 of the flying fork 21 from the second end 33b of the abutting rod 33 through the threading opening 332. The wire hole 213 of the flying fork 21 passes through the axis of the flying fork 21 and is clamped by a wire gripper C; wherein the wire L is reserved for a length at the wire gripper C, It is gradually released for subsequent winding, and the wire C is provided with a function of storing the wire and maintaining tension. The other end of the wire L is located in a wire storage device (not shown) and is tensioned by a force device (not shown); accordingly, the total length of the wire L can be long (for example, tens M), and gradually discharge according to the amount used for winding work. In addition, a portion of the wire L spanning the flying fork 21 is located in the winding zone Z, and preferably abuts against the edge of the winding zone Z (ie, abuts against the stabilizer block 311 or the sleeve 35, The diagram of the embodiment is illustrated as an example of the stabilization block 311, but is not limited thereto.

Referring to Figures 6 and 10, when winding a coil 4 having a single layer of wire L in the radial direction, the winding rod 31 is driven to rotate by the base speed rotary power source 32, and is further driven by the double speed rotary power source 22. The flying fork 21 rotates, and the rotation direction of the winding rod 31 and the flying fork 21 are the same, and the rotation speed of the flying fork 21 is several times the rotation speed of the winding rod 31; Driving the second block 12 to produce a linear displacement relative to the first block 11 such that the second block 12 and the flying fork 21 are axially displaced relative to the winding bar 31 (eg, away from the The direction of the winding rod 31 is displaced to generate a winding path as shown in FIG. 11 so that the flying fork 21 can wind the wire L in the winding zone Z and maintain the wire L attached. The bobbin 31 is used to increase the axial height of the coil 4.

Referring to Figures 6 and 12, after the winding operation is completed, the wire L can be cut by a thread cutter (not shown), and the wire L can be pulled from the portion passing through the wire hole 213 to the clamp. At the wire C, the wire clamp C holds and stores the wire to successively wind the next coil 4. On the other hand, the telescopic power source 34 controls the resisting rod 33 to be displaced relative to the second block 12, and the resisting rod 33 is displaced away from the winding rod 31 to separate the sleeve 35 from the The winding rod 31 is further pulled by a feeding member (not shown) to wind the coil 4 wound on the winding rod 31, so that the coil 4 is detached from the free end of the winding rod 31, thereby obtaining a A coil 4 having a single layer of wire L in the radial direction, the coil 4 having a first end 41 and a second end 42 for attachment to other components. When the other coil 4 is to be wound, the telescopic power source 34 controls the displacement of the abutment lever 33 relative to the second block 12 to bring the abutment lever 33 toward the winding rod 31. 35 is again inserted into the free end of the bobbin 31 to a predetermined depth to repeat the above action.

Referring to Figures 6 and 13, in a similar manner to the above, the coil winding device only needs to increase the number of revolutions of the winding rod 31 and cooperate with the flying fork 21 to reciprocally relative to the winding rod. 31 generates an axial displacement, that is, a coil 4' having two or more layers of wires L in the radial direction.

In detail, the base rod rotating power source 32 drives the winding rod 31 to rotate, so as to wind up the portion of the wire rod L that is reserved, so that a part of the wire L can be produced as The radially expanded winding path is shown in FIG. At the same time, the flying fork 21 is rotated by the double-speed rotating power source 22, and the winding rod 31 and the flying fork 21 are rotated in the same direction, and the rotating speed of the flying fork 21 is several times the rotation speed of the winding rod 31. And when the flying fork 21 rotates, the second block 12 is driven by the telescopic controller 13 to reciprocally generate a linear displacement relative to the first block 11, so that the flying fork 21 is also reciprocally opposite to the The winding bar 31 produces an axial displacement to produce a winding path that is S-shaped in cross section as shown in FIG.

Wherein, the rotational speed setting of the flying fork 21 and the winding rod 31 depends on the axial height of the coil 4' to be wound; for example, the coil 4 having the thickness of the four layers of the wire L in the axial direction is to be wound. 'When the flying fork 21 is required to rotate three times the rotation speed of the winding rod 31; to wind the coil 4' having the thickness of the six layers of the wire L in the axial direction, the rotation speed of the flying fork 21 needs to be the winding Wire rod Five times the rotational speed of 31; when winding a coil 4' having a thickness of nine layers of wire L in the axial direction, the rotational speed of the flying fork 21 is required to be eight times the rotational speed of the winding rod 31, and so on. The purpose of the speed difference is to allow the flying fork 21 to complete the axial direction of the coil 4' with the winding rod 31 in a time interval in which the flying fork 21 is axially displaced with respect to the winding rod 31. Winding operation of the same layer of wire L; in other words, in the time course in which the flying fork 21 is axially displaced with respect to the winding rod 31 for the first time, the flying fork 21 and the winding rod 31 can complete the coil 4 together 'the winding portion of the innermost layer in the radial direction; the flying fork 21 and the winding rod 31 can complete the coil together in the time course of the second axial displacement relative to the winding rod 31 4' in the radial direction of the winding portion of the second layer, and so on, thereby maintaining the winding portion of each layer of the coil 4' can be wound and formed in a smooth and orderly manner, thereby completing a winding of a double layer or three in the radial direction The coil 4' of the wire L above the layer is provided to meet different usage requirements.

Referring to FIG. 14, since the coil winding device can be used to wind the coil 4" having the plurality of wires L in the radial direction, the axial height of the coil 4" can be reduced, and the diameter of the coil 4" can be increased. The number of layers of wire L makes the coil 4" suitable for use in a thin assembly space and still has quite good performance; especially when the coil 4" has an even number of wires L in the radial direction, the coil 4" The first end 41" and the second end 42" may also be disposed adjacent to each other, and have the effect of improving ease of use.

As can be seen from the above, the coil winding device can provide a winding method for winding a wire to form a coil having an N-layer wire thickness in the axial direction, the coil winding method comprising the steps of dividing the wire into a first portion and a second portion connected to each other, the first portion of the wire has one end of the wire, and the second portion of the wire has the other end of the wire; the wire is wound by a base speed winding module The first part is wound on a winding rod at an X speed; the second part of the wire is wound at (N-1)X speed while the axial speed displacement is generated by the double speed winding module relative to the winding rod Wrap around the bobbin. Wherein, the coil has a thickness of two or more layers in the axial direction, so N is a natural number greater than 1.

In addition, the double speed winding module reciprocally generates an axial displacement relative to the winding rod to wind a coil having two or more layers of wire in the radial direction. Moreover, the double speed winding module can complete the winding operation of the same layer of wire in the axial direction of the coil in the time course of the axial displacement of the winding rod in a single time. In order to maintain the winding portions of each layer of the coil, the winding can be formed in a smooth and orderly manner.

In addition, the first end and the second end of the coil wound by the winding method are always located at the outermost layer in the radial direction of the coil, and can be directly pulled to be connected with other members, thereby completely solving the conventional coil. One end of the head needs to cross from the inner layer to the outer layer, so as to increase the axial height of the overall coil; in other words, the coil wound by the coil winding device or the winding method of the present invention has an axial height Smaller, it can save the assembly space occupied, and can be applied to electronic and motor products with light and thin development.

It is worth mentioning that the more the number of radial layers of the coil to be wound, the longer the reserved length of the wire drawn to the wire gripper, and the ones in the field who have the usual knowledge can Adjust the reserved length. Moreover, the coil that has been wound should be cured before it is detached from the bobbin, and the coil is cured. The manner of curing the coil is a conventional technique and is not the focus of the present invention and will not be described in detail. In addition, the above description is based on the example of winding a "frameless air-core coil", but the coil winding device and the coil winding method of the present invention can also be used to wind a bobbin coil. Those of ordinary skill in the art will understand and adapt, and are not limited by the present invention.

In summary, the coil winding device and the coil winding method of the present invention allow both ends of the wound coil to be located at the outermost layer of the coil to avoid increasing the axial height of the overall coil.

The coil winding device and the coil winding method of the invention can wind single-layer, double-layer and three-layer coils of wire layers to meet different use requirements.

Although the present invention has been disclosed using the above preferred embodiments, it is not intended to be limiting The present invention is not limited to the spirit and scope of the present invention, and various modifications and changes to the above embodiments are still within the technical scope of the present invention. Therefore, the scope of protection of the present invention is attached. The scope defined in the scope of application for patent application shall prevail.
