Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an armature coil winding device for a flat motor.

Conventionally, winding work for this type of armature coil has relied exclusively on manual labor, but the work requires a lot of time.

In addition, although there has been a desire for automatic winding for a long time, there is still no device that can automatically wind winding devices because it has to be wound into a complicated shape and there is no suitable winding wire. .

The present invention focuses on the above points and provides a device that can automatically wind the armature coil of a flat motor using a simple winding jig.

Hereinafter, the configuration of the present invention will be explained in more detail based on the drawings of one embodiment. Reference numeral 1 denotes a pedestal for supporting the entire apparatus, and a support 2 is provided at the center of the pedestal 1. A turntable 3 is rotatably supported by the support column 2''.

Reference numeral 6 denotes a guide bin that is biased by a fluid or gas cylinder and positions the turntable 3 at a predetermined position. Reference numeral 60 denotes an index table rotatably supported by a thrust bearing 61 on the turntable 3-F.
An index gear 7 is fixed to the lower part of o. 8
is a rotary plate fixed to the upper surface of the index table 60, which rotates the index together with the index table 6o. A hole 8-1 is formed in the center of the rotary plate 8 to allow a coil tap connected to the commutator to be pulled out downward. For this reason, the rotary plate 8 has a donut shape. A gear 9 meshes with the index gear 7, and this gear 9 is driven by a stepping motor 1o. The meshing between this gear 9 and the index gear 7 is based on the air cylinder 12.
It is configured to be operated intermittently by a lever 11 operated by a lever 11.

A twist pin 13 is connected to the twist motor 14 via a spring 15 to prevent wire breakage due to the total length of the coil tap 16 becoming known as the coil tap 16 is twisted. Also twist mode 1
4 is provided with an air cylinder 17 that slides left and right to remove the twisted coil tap 16 after twisting. Further, these twist mechanisms are configured to be moved up and down by an air cylinder 18.

Reference numeral 19 denotes a column that supports the upper device of the wire winding and assembly station A. A guide holder 20 is provided on the upper portion of the column, and a guide post 21 is supported by the guide holder 20. Further, a slide base 22 is provided on the guide post 21 so as to be movable up and down by a guide bush 23.
The entire upper device of the winding and assembling station A attached thereto is configured to move up and down. The vertical movement of the entire upper device of the winding and assembling station is carried out by the air cylinder 24.
carried out by A guide holder 25 is further provided above the slide pace 22, and a guide post 26 is supported by the guide holder 25. A re-slide base 28 is supported by a guide bush 27 on the guide post 26 so as to be moved up and down by the operation of an air cylinder 29. Further, a ball bearing 30 is fitted to one end of the slide pace 28. A core shaft 31 is press-fitted into the ball bearing 30 from below, and a fixing screw 32 is attached to the upper end of the core shaft 31 . Further, the winding core shaft 31 is provided with a through hole 31-1 that passes through the bottom. Also, a nozzle 31-2 is provided at the upper end of this winding core shaft 31,
The center part is a spline shaft 31 with splines formed on the outer periphery.
-3. Also, a part of the lower end has a notch 31-
4, and the guide reel 3 is installed in this notch 31-4.
3 are available for transfer. Furthermore, a ball bearing 34 is fitted in the lower end opening.

Reference numeral 35 denotes a spline sleeve, a ball bearing 36 is fitted into the middle part of its outer periphery, and a pulley 37 is fixed to the upper end by a fixing screw 38. Further, a rotary nozzle 4o supported by an arm 39 is attached to the lower end of this spline sleeve 35, and an electromagnetic wire,
For example, an enamelled copper wire 41 is connected to the rotating nozzle 4.
Guided within o. In particular, the electromagnetic wire 41 is an enameled wire whose surface is coated with a heat-fusible coating material such as phenol, epoxy, aluminum, or butyral. 4
2 is a rotation stopper pin of the fan-shaped winding jig 43 attached as described later, and is attached to the tip of the air cylinder 44.
When the 1st) winding jig 43 slides upward or downward from the upper limit position, it engages with the positioning notch 50-1 of the 1st winding jig 43, The jig 43 and the rotary plate 8 are prevented from rotating so that relative positional deviation does not occur.

The winding jig, for example, the first winding jig 43 is a main component of the present invention, and is supported by a shaft 45 rotatably supported by the pole bearing 34 fitted into the lower end opening of the winding core shaft 31. It is supported coaxially with the winding core shaft 31, is given a suitable pressurization by a coil spring 46 wound around a shaft 45, and faces the rotary plate 8 with a predetermined gap therebetween.

In addition, the first winding jig 43 has a spring pin 47 that forms a hexagonal coil at a position close to the center of the rotary plate 8.
The two spring pins 47, which are also provided at distant positions, are slidable up and down and are applied with a suitable downward pressure by a coil spring 48.

The spring pressure of the coil spring 46 inserted into the shaft 45 and pressing the first volume jig 43 is several times stronger than that of the coil spring 48 inserted into the coil pin 47. The spring pressure of the coil spring 46 is set to an appropriate value depending on the wire diameter (wire rigidity) of the electromagnetic wire 41 to be wound and the tension applied thereto. If the force is too strong, the space between the rotary plate 8 and the first winding jig 43 will remain narrow at the beginning of winding, and the first winding jig 43 will not be able to move upward easily, so that the already wound coil When winding a coil on top of the other, the already wound coil interferes with winding the coil into a predetermined shape. Moreover, the coil shape becomes uneven between the beginning and the end of winding, and the outer circumference (horizontal)
The coils are wound one after another so as to extend in the same direction, making it impossible to form them into a predetermined outer peripheral shape.

If it is too weak, the coil will not stretch in the outer circumferential direction, but the coil thickness in the winding direction will increase, making it difficult to form the coil into a predetermined shape as described above.

49 is a slide plate through which the spring pin 47 passes and is screwed to the shaft 45. As is clear from this configuration, when the shaft 45 slides, the upper surface of the slide plate 49 pushes up the flange of the spring pin 47, and the spring IJ pin 47 protruding from the lower surface of the first volume jig 43 is moved. It is configured to be hauntable.

Reference numeral 50 denotes a cover provided on the upper surface of the first winding jig 43, which supports the spring pin 47 in a slidable manner, and whose central portion serves as a bearing post for the shaft 45. Therefore, the cover 50 is made of sintered oil-impregnated bearing material. As shown in FIG. 5, the rotating plate 8 has a plurality of pins 51 installed at the same distance from the center of rotation of the rotating plate 8 and slightly outside the inner spring pin 47. Similarly, a plurality of pins 52 are installed at the same distance from the center of rotation of the rotary plate 8 and slightly inside the outer spring pins 47.

In one embodiment of the present invention, these pins 51 and 52 are each 28 in number, and cooperate with the three pins 47 to wind a heptagonal coil as shown in FIG. It has become. In this case, the coils are not wound around adjacent pins, but around four pins apart.

53 is a recess provided below the first volume jig 43, consisting of an arcuate groove having the same radius as the pin 51.52, and slightly wider than the diameter of the pin 51.52; The depth is set so that the tip of the pin bit 52 will not touch the upper bottom of the recess 53 even when the jig 43 is pressed against an eye extraction plate 54 to be described later. The ejection plate 54 is connected to the pin 51.
The rotary plate 8 has 56 holes that allow each of the 52 holes to pass through, and is arranged on the concave portion 8-2 of the rotary plate 8. Reference numeral 55 denotes a disk-shaped second volume jig, and a part of its outer periphery is attached to a mounting bolt 56 by a support pin 56-1 so as to be openable and closable. 57
and 58 are arcuate grooves having the same radius as the bins 51 and 52 and formed on the lower surface of the disc-shaped winding jig 55, and having the same width as the recess 53. A coil spring 59 is wound around the outer periphery of the mounting pole 56 to hold the second volume jig 55 at a predetermined height. 56-2 is the support bin 5
The attachment is formed in the ball 56 with a long groove that allows movement of the ball 6-1 by a predetermined distance up and down. This coil spring 59
The second winding jig 55 is pushed upward in advance, and when indexing the index table 60 after winding, an appropriate loose relationship is maintained between the bins 51, 52, the recesses 53, and the arcuate grooves 57 and 58. This is to eliminate the complicated phenomenon between the two and to perform smooth indexing.

Other important functions include maintaining an appropriate gap between the second volume jig 55 and the rotary plate 8, and maintaining the coil 4 when indexed.
When the coil 1A enters under the second volume jig 55, the coil 41A may get caught on the end face of the notch 55-1 of the second volume jig 55, or the coil 41A may rub strongly against the -F side of the second volume jig 55. This is to index the total of 7 yen without being lost. In addition, by supporting the support bottle 56-1 in a slidable manner within the long groove 56-2, when the second jig 55 is pressed with the one-way block 66 (to be described later), the second roll jig 55
and the rotary plate 8, and press and shape the wound coil 8 into a predetermined flat shape 752'1liS
It is something that will make you happy.

Note that the two sides of the discharge plate 54 are treated with oat ζ coving using Teflon or ceramic, so that even if a coil yoke 75 is formed during heating with electricity,
To prevent short-circuit damage, to prevent heat dissipation during energization heating, and to facilitate coil shaping when discharging the coil at the end of winding. Moreover, the lower surface of the second volume jig 55 is also overcoated as in the case of Shō II. 55-1 is a fan-shaped notch formed in a part of the second volume jig 55, and this notch 55-1 is used for the pins 57 and 58.
It is said to be slightly smaller than the 6-pitch. This is to prevent the coil from being wound on pins outside this pitch when the coil is wound with a pitch of 4. This notch 55-1 allows insertion of the first volume jig 43, but a gap G is provided between the two to allow the electromagnetic wire 41 to fall along the outer circumferential surface of the first volume jig 43. ing. The angular pitch of the lower end flat part of the first winding jig 43 is the pitch of the bins 51 and 52 around which the coil is wound (here, 4 pitches).
It is considered more like a dog.

A recess 60 is provided on the outer peripheral side of the index table 60.
-1 is provided, and a steel ball 60-2 is provided in the recess.
It is pressed by a coil spring 60-3 to ensure accurate positioning of the index.

A thrust bearing 61 supports the index table 60.

62 is a coil winding start clamp, and 63 is a winding end clamp, which are provided on the index table 60. After the winding is finished, the beginning and end of the coil are clamped by the clamps 62 and 63, but during this clamping, the clamping teeth of the clamps 62 and 63 break the coating of the electromagnetic wire 41, causing internal damage. core m<#iI
line).

Therefore, the clamps 62, 63 and the electromagnetic wire 41 are electrically connected. In such a state, the clamp 62.6
When a predetermined amount of current is applied to the coil 4'A, the wound coil 4'A generates heat, the heat-sealing coating of the coil 41A melts, and the electromagnetic wire □ comrade is attached. The L-C is specified. By cooling for a period of time, the heat-sealed coating material hardens and a rigidly shaped coil winding set is obtained. Reference numeral 64 is a current-carrying electrode that energizes the clamps 62 and 63, which is moved up and down by an air cylinder 65. It is said to be free. A suppressing block 66 is provided at the lower end of this air cylinder 65, and this suppressing block 66 includes a pressing body 66-1 that presses the second volume jig 55 downward when the coil 41A is energized and heated.
and the fan-shaped pressing body 6 that directly applies pressing force jJ to the coil 41A through the M+cedar notch 55-1 of this second volume jig 55.
6-2. 67 is a column that supports the suppressing energization heating shaping section and the energizing energizing section; 68 is a winding core shaft 31;
The timing belt transmits the rotation to the rotor, and a timing mode (not shown) or the like is used to generate the rotational force, and is equipped with a position detection sensor (not shown) to always stop the rotating nozzle 40 at a fixed position.

In the above, the unit on the turntable 3 is divided into a winding and assembling station A, a coil forming and fixing station B by energization heating, and a discharge station as shown in FIG. By combining these in a double or triple manner, it is possible to obtain a winding machine with even higher manufacturing capacity. That is, a winding and assembling station A is arranged at the starting point of the turntable 3, a coil forming and fixing station B using electrical heating is arranged at a position 120 degrees from the starting point, and further 2 coil forming and fixing stations from the starting point are arranged.
The ejection station is located at a 40 degree angle. At the discharge station, this is not done unmanned; instead, the discharge plate 54 is moved by a cylinder (not shown) through the index table 60 and rotary plate 8 through a through hole (not shown) and a cylinder pin (not shown). Push down the ejection plate 54 and press the pins 47, 51 and 5.
This makes it easy to remove the coil 41A wound around the coil 2 from these pins.

Next, operations in the configuration of the above embodiment will be sequentially explained.

When you press the start button (not shown), turntable 3
The guide pin 6 comes off, and the turntable 3 becomes ready to rotate. In this state, the gear motor 5 rotates a predetermined amount,
Rotate the turntable 3 by index. Due to this index rotation, the jig from which the armature coil assembly has been assembled and removed is conveyed to the winding and assembly station A by the discharge stay/con, and the guide pin 6 is moved again to the turntable 3 by 6 degrees.
The turntable 3 is positioned and held.

Next, operate the various cylinders attached to the device, set the device as shown in FIG. Clamp as shown. The electromagnetic wire 41 is given appropriate tension by a tension mechanism (not shown), passes through the core shaft 31, and is connected to the guide reel 33.
It further passes through the rotary nozzle 4o, and its tip begins to wind as described above and is clamped by the clamp 62.

The state shown in FIG. 2 is the state in which winding is possible. That is, the first
The winding jig 43 enters the notch 55-1 of the second winding jig 55, and the coil spring 46 brings the first winding jig 43 close to the surface of the discharge plate 54 with a slight gap. be. At this time, the lower ends of the five spring pins 47 are in contact with the surface of the discharge plate 54 under a predetermined pressure due to the biasing force of the spring 43. In addition, rotating plate 8
As mentioned above, the pins jl and 52 are installed in the hexagonal coil 41 by these pins 47 and 51.
Winding of A becomes possible.

In this state, when the winding stepping mode (not shown) rotates, the rotational force is applied to the pulley 37 and the spline sleeve 35 via the timing belt 68.
The rotational nozzle 40 is rotated. Rotating nozzle 40
As the coil 41 rotates, a coil 41 is unwound from a coil bobbin (not shown), and a coil tension mechanism (not shown) applies appropriate tension to the winding core shaft 3.
1 is energized, guided by the guide reel 33, further passes through the rotating nozzle 40, slides on the side wall surface that becomes the guide part 43A of the first winding jig 43, and is sequentially wound around the pins 51 and 52 of the rotating plate 8. . At this time, the first volume jig 43 is the core/gift 31.
is in a lowered state and the spring pin 47 protrudes downward and is in contact with the discharge plate 54, so the coil is connected to the pins 51, 52 and this spring pin 47
It is wound around a windshield, and its shape becomes a heptagonal shape as shown in FIG. However, when the predetermined number of windings are completed, the rotating nozzle 4
0 stops at a fixed position. It is extremely difficult to wind the coil 41A in a narrow space (particularly the pitch of the pins 51), and if the coil 41A spreads out horizontally or becomes thicker upwards, this method is very difficult. In the example, the first volume jig 43 is pressed with a moderate force by the coil spring 46,
Since a suitable tension is also applied to the electromagnetic wire 41, the first winding jig 43 rises slightly as the coil 41A is wound, and the coil 41A is wound in an orderly manner. Further, at this time, since the fan-shaped angle of the first winding jig 43 and the notch 55-1 of the second winding jig 55 have an appropriate dimensional relationship, winding can be ensured around the predetermined pins 51 and 52.

After winding a predetermined number of times, the air cylinder 18 operates,
Twist pin 13 rises. The electromagnetic wire 41 is hooked to the hook portion of the twist bin 13 by winding the rotary nozzle 40 one more turn. When the rotary nozzle 40 completes one rotation, the air cylinder 18 moves downward and is rotated by the twist motor 14 several times to return the twist bin 13 to its home position.

When one set of coil winding is completed in this way, the air cylinder 29 is operated to raise the winding core shaft 31 in an intermediate position as shown in FIG.

When the winding core shaft 31 rises -F to the intermediate position, the three spring pins 47 protruding from the lower part of the first winding jig 43 each resist the spring force of the coil spring 48, as shown in FIG. It is pulled up by the slide plate 49 and drawn into the first winding jig 43.

By raising the winding core shaft 31 to the intermediate position @, the slide plate 49 fixed to the tip of the shaft 45 also rises. The first volume jig 43 is pushed downward by the coil spring 46, but stops when the slide plate 49 hits the cup 50. By adjusting the intermediate rise amount of the winding core shaft 31, the gap between the lower surface of the first winding jig 43 and the rotary plate 8 can be set arbitrarily. In addition, as shown in FIG.
By appropriately setting the amount of upward movement of the first winding jig 43 within the range where it comes off from the recess 53 provided in the coil 41A.
Since the pressing force acting on the coil 41A is reduced and the wound coil 41A does not come off the pins 51, 52, the subsequent indexing of the rotary plate 8 becomes easy and reliable. Next, when the stepping mode 10 is operated, a predetermined pitch (in the present invention, 28 coils, a 6-pole magnet, and a wave winding connection is used, so the pitch is 115°43')
) is indexed.

At this time, the completed coil 41A is still pressed by the first winding jig 43, and upward floating phenomenon due to springback is prevented, so this coil 41A is moved to the second winding jig 43. The pins 51 and 52 are engaged in the gap between the discharge plate 55 and the discharge plate 54, and the discharge plate 55 is pulled and fed smoothly.

Also, at this time, the side opposite to the notch of the second volume jig 55 is raised upward by a predetermined distance by the coil spring 59, so that the pin 5
1.52 and the arcuate grooves 53, 57.58 is maintained, allowing smooth indexing. Furthermore,
The second width jig 55 is made of iron and has a corresponding weight in order to press the plural sets of coils indexed and fed into the gap with appropriate pressure.

When the first index is completed in this way, the third
The first winding jig 43 at the intermediate position shown in the figure is lowered again to the state shown in FIG. 2, and the next set of coils 41A winding bins 51.
52 and rotate the rotary nozzle 40 again to wind the coil 41A.

When indexing of the rotary plate 8 starts, the twist mode 14 rotates and the coil tap 16 is twisted a predetermined number of times. When the twisting is completed, the twist bin stops facing in a certain direction, and then the air cylinder 17 is operated to move the twist bin 13 left and right to remove the coil tap 16 from the hook portion. When the winding of a predetermined number of coils 41A is completed by repeating this process, the first winding jig 43 is raised and the turntable is moved +171J.
If the first winding jig 43 rises immediately after winding, the wound coil group will float up, so when the winding is finished, the air cylinder 29 operates to raise the winding core shaft 31 halfway up, The spring pin 47 of the first-volume jig 43 is buried in the first-volume jig 43, and then a predetermined indexing is performed once. By doing so, the last wound coil 41A is held in the second winding jig 55, and the coil group is prevented from lifting up. However, at this time, the silk coil 41 wrapped in the middle appears in the notch 55-1, but this coil is then held down by the coil wrapped over the coin holder, so it cannot float up. indexing is done smoothly. The winding end of the coil 41A is clamped by a winding end clamper 63 and cut by a cutting tool (not shown). In this state, the air cylinder 24 is operated, and the entire upper device of the winding and assembling station is moved upward as shown in FIG. At this time, since the first roll jig 43 comes to a free state, the air cylinder 44 operates a moment earlier than the operation of the air cylinder 24, and the rotation stopper 42 is activated.
It engages with the notch of the blind cover 50 and prevents the first volume jig 43 from rotating.

The turntable 3 is then indexed, for example by 120 degrees, and the coil 41A group is sent to the next coil forming and fixing station B. At this station B, the air cylinder 65 is operated, and the coil 41 group is pressed and shaped by the pressing block 66, and at the same time, the energizing electrode 64 is connected to the clamp <62° 63 and energized. The suppressing block 66 has a pressing body 66-1 that presses the second volume jig 55 and a fan-shaped suppressing body 66-1 that directly presses the coil 41A through the notch 55-1.
Pressure shaping of A can be performed almost perfectly. At this open winding wire assembly station A, a series of wire winding operations are repeated. After being energized for a predetermined period of time, the energization is stopped, but thereafter the air cylinder 65 is left in a suppressed and shaped state for a certain period of time (25 to 30 seconds), and the air cylinder 65 returns to its original upper position. When a series of winding steps at the winding and assembling station are completed, the turntable 3 is further indexed by 120 degrees. At the next discharge station, the coil-41A assembly thus formed is opened by opening the second winding jig 55 with the support pin 56-1 as a fulcrum, and the discharge plate 54 is moved by an air cylinder (not shown). It is pushed up, thereby making it possible to take out the completed flat coil assembly. The coil after shaping can be taken out manually or automatically, but in either case, the ejection plate 54 makes it easy to take out the coil, which is preferable.

The configurations of the embodiments of the present invention described above can be considered as equivalents as follows.

(a) The number and position of the pins 51, 52 and the spring pin 47 can be changed as appropriate depending on the shape of the coil to be wound. Also, certain pins may be omitted depending on the shape of the coil.

(b) Various cylinders can be used for fluids or gases. Alternatively, an electric motor may be used.

(c) The discharge plate 54 can be omitted.

However, in this case, it is necessary to coat the surface of the rotating plate 8 with oats.

) The spring force of the coil spring 46 that presses the first volume jig 43 is determined by the tension applied to the electromagnetic wire 41 and the rotating nozzle 4.
Preferably, it is adjustable by a rotational speed of 0. As a result, the wire diameter of the electromagnetic wire 41 to be handled is not specified.

(e) The turntable 3 can be replaced by a linearly moving conveyance device.

(f) The rotary plate 8 and the index table 60 may be integrated.

(g) This device can also be used as a whole horizontally.

As explained above, the present invention uses a rotary plate provided with a large number of pins, and winds an electromagnetic wire using a winding jig having a guide portion on a specific pin of the pins, thereby winding a coil. With this configuration, the time required for winding the armature coil of a flat motor can be significantly reduced.

However, it is understood that the present invention is not limited to the one embodiment described above, but includes various alternative techniques and applied techniques without departing from the scope of the claims.
