Although not shown, it is needless to say that various arrangements for adjusting the spacing between the guide block 331 and the first feeding roller 310 and the second feeding roller 320 may be proposed.

7 is a view showing the inside of a guide block according to an embodiment of the present invention. Referring to FIG. 7, an air inlet 338 for introducing air into the groove 337 may be formed on the inner surface of the groove 337 formed in the guide block 331. The air inlet 338 is connected to an air source (not shown). The air supplied from the air supply source to the air inlet 338 flows into the groove 337.

The air flowing into the groove 337 can reduce the frictional force between the flat wire 30 and the inner side surface of the groove 337 so that the flat wire 30 can smoothly move along the groove 337. In this case, the load applied to the first feeding roller 310 and the second feeding roller 320 for pushing out the flat wire 30 can be reduced.

In this case, the load applied to the first feeding roller 310 and the second feeding roller 320 for pushing out the flat wire 30 can be reduced.

Referring to FIG. 4, the flat wire feeding mechanism 300 may further include an adhesion adjusting unit 350. The adhesion force adjusting unit 350 adjusts the adhesion between the first feeding roller 310 and the second feeding roller 320.

For example, the adhesion adjusting unit 350 includes a first block 351, a second block 352, a support bar 353, a moving member 354, an elastic member 355, 356, and an adjustment bolt 357.

And the movable member 354 moves along the support bar 353. The movable member 354 may be disposed over the pair of support bars 353 as shown in Fig.

The elastic member 355 provides an elastic force for bringing the second block 352 closer to the first block 351 side between the moving member 354 and the second block 352. [ At this time, the elastic member 355 may have a coil spring shape as shown in FIG. 4, and the support bar 353 may be arranged to penetrate the elastic member 355. One end of the elastic member 355 is in contact with the moving member 354 and the other end of the elastic member 355 is in contact with the second block 352.

The fixing member 356 is fixed to the end of the support bar 353. The fixing member 356 is disposed over the pair of support bars 353 as shown in Fig.

The adjusting bolt 357 penetrates through the fixing member 356 and contacts the moving member 354.

When the adjusting bolt 357 is tightened, the adjusting bolt 357 pushes the moving member 354 toward the first block 351 to press the elastic member 355, thereby increasing the elastic force of the elastic member 355. In this case, the adhesion force for bringing the second block 352 into close contact with the first block 351 increases.

When the adjustment bolt 357 is disengaged, the elastic force of the elastic member 355 decreases. In this case, the adhesion force for bringing the second block 352 into close contact with the first block 351 decreases.

Thus, the adhesion force adjusting unit 350 can adjust the adhesion between the first block 351 and the second block 352 with a simple structure.

For example, when the flat wire 30 needs to move freely with respect to the first feeding roller 310 and the second feeding roller 320 in the operation of the flat wire coil forming apparatus (10 in FIG. 1) The adhesion force between the first feeding roller 310 and the second feeding roller 320 can be minimized by operating the adhesion force adjusting portion 350. [

The operator can adjust the adhesion between the first feeding roller 310 and the second feeding roller 320 according to the thickness of the flat wire 30 to perform a feeding operation corresponding to the thickness of the flat wire 30 have.

In order to eliminate or minimize the slip that may occur between the first feeding roller 310 and the second feeding roller 320 during the conveying process, the operator operates the adhesion adjusting unit 350 to adjust the first The adhesion between the feeding roller 310 and the second feeding roller 320 can be maximized.

It is needless to say that various types of adhesion adjusting parts for adjusting the adhesion between the first block 351 and the second block 352 may be proposed.

Referring to FIG. 1, the flat wire coil forming apparatus may further include a feed amount measuring mechanism 500.

For example, the feed amount measuring mechanism 500 may include a first measuring roller 510, a second measuring roller 520, a rotating plate 530, and a light sensor 540.

The first measuring roller 510 and the second measuring roller 520 come into close contact with the width Sb of the flat wire 30 and are moved by the frictional force with the flat wire 30 when the flat wire 30 moves. Rotate. At this time, the first measuring roller 510 and the second measuring roller 520 rotate in mutually opposite directions. The first measuring roller 510 and the second measuring roller 520 are rotatably supported by a jig (not shown).

The first measuring roller 510 and the second measuring roller 520 are in close contact with each other so as not to cause slippage with the flat wire 30 without interfering with the feeding of the flat wire 30. A slip member (not shown) having a rubber-like material may be attached to the surface of the first measuring roller 510 and the second measuring roller 520 to prevent slippage with the flat wire 30.

The rotating plate 530 has the same rotational axis 535 as the first measuring roller 510 and rotates together with the first measuring roller 510. A plurality of through holes 531 are formed in the rotary plate 530, and the plurality of through holes 531 are radially spaced apart from each other at equal intervals around the rotary shaft 535.

The optical sensor 540 includes a light emitting portion 541 and a light receiving portion 542 facing each other with respect to the through hole 531 of the rotating plate 530. The light sensor 540 is disposed between the light emitting portion 541 and the light receiving portion 542 in a state where the light receiving portion 542 receives light in the process of continuously emitting light from the light emitting portion 541 toward the light receiving portion 542, And the light receiving unit 542 can not receive light. For example, a state in which the light-receiving unit 542 receives light and a state in which the light-receiving unit 542 receives light is recognized as "1 ".

The operation of the feed amount measuring mechanism 500 configured as described above is as follows.

First, when the flat wire 30 is fed to the coil generating mechanism 200 side by the flat wire feeding mechanism 300, the friction between the first measuring roller 510 and the second flattening wire 30, The measuring rollers 520 rotate in mutually opposite directions.

When the first measuring roller 510 rotates, the rotary plate 530 rotates together. At this time, a plurality of through holes 531 formed in the rotary plate 530 sequentially pass through the optical sensor 540. At this time, the number of the through holes 531 passing through the optical sensor 540 through the optical sensor 540 can be counted.

The angle at which the rotary plate 530 is rotated is obtained through the number of the counted through holes 531 and the feed amount of the flat wire 30 can be calculated through the rotation angle of the rotary plate 530. [

4) and the second feeding roller (320 in FIG. 4) in the process of feeding the flat wire 30 to the coil generating mechanism 200, 30), only the operation of the servomotor that drives the first feeding roller 310 (FIG. 4) and the second feeding roller 320 (FIG. 4) (200 in Fig. 1).

That is, when a slip occurs between the first feeding roller 310 (FIG. 4) and the second feeding roller 320 (FIG. 4) and the flat wire 30, the servomotor feeds the flat wire 30 by a predetermined length The actual flat wire 30 is not fed by the set length.

If the feed amount of the flat wire 30 measured by the feed amount measuring mechanism 500 does not reach the set value in this situation, the flat wire feeding mechanism 300 continues to feed the flat wire 30 until the feed amount of the flat wire 30 reaches the set value Can operate.

Referring to FIG. 1, the flat wire coil forming apparatus 10 may further include a deflection preventing mechanism 600. The deflection preventing mechanism 600 is interposed between the flat wire feeding mechanism 300 and the flat wire feeding mechanism 200 to prevent the flat wire 30 from being deflected during the feeding process.

FIG. 10 is a side view of a deflection prevention mechanism according to an embodiment of the present invention, and FIG. 11 is a plan view of a deflection prevention mechanism according to an embodiment of the present invention. 2, 10, and 11, the deflection preventing mechanism 600 includes a first deflection preventing portion 610 for preventing the flat wire 30 from being deflected in the thickness direction (e.g., the Y axis direction) And a second deflection preventing portion 630 that prevents the first deflecting portion 30 from being deflected in the width direction (e.g., the Z axis direction).

For example, the first deflection prevention unit 610 may include a first deflection prevention jig 611, a first deflection prevention roller 613, and a first deflection position adjustment unit 615.

The first deflection prevention jig 611 is supported by the first deflection prevention roller 613. The first deflection preventing roller 613 contacts the width Sb of the flat wire 30 and prevents the flat wire 30 from being deflected in the thickness direction.

A plurality of first deflection preventing rollers 613 are provided and the plurality of first deflection preventing rollers 613 are arranged in a zigzag form in the moving direction of the flat wire 30 about the flat wire 30. The first deflection preventing roller 613 may be formed with a groove (not shown) corresponding to the flat wire 30.

The first deflection position adjuster 615 adjusts the thickness direction position of each of the first deflection prevention rollers 613 with respect to the first deflection prevention jig 611. For example, the first deflection position adjuster 615 may include a first moving block 6151 and a first adjusting bolt 6152. The first moving block 6151 is movably coupled to the first deflection preventing jig 611 in the thickness direction thereof and the first deflection preventing roller 613 is supported by the first moving block 6151. In this case, the first deflection preventing roller 613 can move in the thickness direction with respect to the first deflection preventing jig 611 while being supported by the first moving block 6151.

A pair of first adjustment bolts 6152 may be used to adjust the position of one first moving block 6151. [ The pair of first adjustment bolts 6152 may respectively contact the first moving block 6151 through the first deflection preventing jig 611 in the thickness direction of the flat wire 30. In the process of unlocking and fixing the first adjustment bolts 6152, the position of the first deflection prevention roller 613 in the thickness direction with respect to the first deflection prevention jig 611 can be adjusted.

For example, the second deflection prevention part 630 may include a second deflection prevention jig 631, a second deflection prevention roller 633, and a second deflection position adjustment part 635. [

And the second deflection prevention roller 633 is supported by the second deflection prevention jig 631. [ The second deflection preventing roller 633 contacts the thickness surface St of the flat wire 30 and prevents the flat wire 30 from being deflected in the width direction.

A plurality of second deflection preventing rollers 633 are provided and the plurality of second deflection preventing rollers 633 are arranged in a zigzag shape in the moving direction of the flat wire 30 about the flat wire 30. The second deflection prevention roller 633 may be formed with a groove (not shown) corresponding to the flat wire 30.

The second deflection position adjuster 635 adjusts the widthwise position of each of the second deflection prevention rollers 633 with respect to the second deflection prevention jig 631. For example, the second biasing position adjuster 635 may include a second moving block 6351 and a second adjusting bolt 6352. The second movement block 6351 is movably coupled to the second deflection prevention jig 631 in the width direction and the second deflection prevention roller 633 is supported on the second movement block 6351. [ In this case, the second deflection preventing roller 633 can be moved in the width direction with respect to the second deflection preventing jig 631 while being supported by the second moving block 6351.

A pair of second adjustment bolts 6352 may be used to adjust the position of one second moving block 6351. [ The pair of second adjustment bolts 6352 can penetrate in the width direction of the second deflection prevention jig 631 and can make contact with the second moving block 6351, respectively. In the course of unlocking and tightening the second adjustment bolts 6352, the widthwise position of the second deflection prevention roller 633 with respect to the second deflection prevention jig 631 can be adjusted.

The operator has a bias phenomenon in the flat wire 30 entering between the one feeding roller 310 of FIG. 4 and the second feeding roller 320 of FIG. 4 in the process of operating the flat wire coil forming apparatus 10 of FIG. The deflection preventing mechanism 600 can be operated so that the bottom flat wire 30 is not deflected but remains in a straight line state.

Such a deflection preventing mechanism 600 is simple in construction and prevents the flat wire 30 from being deflected before entering between the first feeding roller 310 (FIG. 4) and the second feeding roller 320 (FIG. 4).

Although not shown schematically, various types of deflection preventing mechanisms are proposed to prevent the flat wire 30 from being deflected before entering between the first feeding roller (310 in FIG. 4) and the second feeding roller (320 in FIG. 4) Of course.

FIG. 12 is a side view of a coil generating mechanism according to an embodiment of the present invention, and FIG. 13 is a sectional view taken along line D-D of FIG. Referring to FIGS. 2, 3, 12 and 13, the coil generating mechanism 200 includes a jig 210.

A coil member 40 is attached to the jig 210. At this time, the coil member 40 is attached such that one end of the coil member 40 is supported by the jig 210. The coil member 40 can be manually attached to the jig 210 by an operator. Or the coil member 40 can be automatically attached to the jig 210 by a separate actuator.

The coil member 40 is attached to the jig 210 such that the cores 41 and 42 extend in the thickness direction of the flat wire 30.

The jig 210 may have a seating groove 211 in which one end of the coil member 40 is inserted and seated. The seating groove 211 is formed in a shape corresponding to one end of the coil member 40.

A magnet 212 may be installed inside the seating groove 211. In this case, a magnetic force is generated between the coil member 40 and the magnet 45 installed at one end of the coil member 40 inserted into the seating groove 211, so that the coil member 40 can be strongly attached to the seating groove 211 .

A guide groove 213 is formed in the jig 210. The guide groove 213 is formed in the guide groove 213 so that the flat wire 30 conveyed by the flat wire feeding mechanism 300 is wound around one end of the work core 41 of the cores 41 and 42 of the coil member 40, Guide. For reference, the working core 41 is arbitrarily selected among the cores 41 and 42 shown in FIG. 3 for convenience of explanation.

The guide groove 213 partially surrounds the working core 41. [ At this time, the guide groove 213 has an outlet 2137 facing the space between the working core 41 and the remaining core 42 of the coil member 40. Due to the structural characteristics of the guide groove 213, a flat wire coil forming operation for the coil member 40 having the pair of cores 41 and 42 can be performed.

The guide groove 213 may be shallower than the seating groove 211.

The guide groove 213 may have a straight region 2131 in which the flat wire 30 maintains a linear shape and a curved region 2132 that is deformed in a curved shape. In this case, the curved region may have a concentric circular structure or the same center of curvature as the circular cross section of the working core 41.

The flat wire 30 enters the inlet 2136 of the guide groove 213 and then moves in the linear region 2131 while maintaining a straight line shape. The flat wire 30 deformed in a curved shape in the curved region 2132 is continuously wound around the working core 41 after being discharged from the outlet 2137 of the guide groove 213. [

The bottom surface of the guide groove 213 which contacts the width Sb of the flat wire 30 can be placed on a plane perpendicular to the central axis Q of the working core 41. [ For example, the bottom surface of the guide groove 213 may lie on the XZ plane as shown in Figs. In this case, since the state in which the flat wire 30 is perpendicular to the central axis Q of the work core 41 can be maintained considerably and continuously during the winding of the flat wire 30 on the work core 41, (213).

The depth of the guide groove 213 may be the same as the thickness of the flat wire 30, but is not limited thereto.

The tip of the discharged flat wire 30 moving along the guide groove 213 can hit the inner surface of the seating groove 211 during the first rotation of the core. In this case, the flat wire 30 may be damaged or the flat wire coil molding may be interrupted.

To solve this problem, the jig 210 is formed with an inclined surface 2111. The inclined plane 2111 is inclined so that the tip of the flat wire 30 rides over in the course of the first round of the work core 41 by the flat wire 30. The inclined plane 2111 is formed at one side of the seating groove 211 facing the outlet 2137 of the guide groove 213 through which the tip of the flat wire 30 is discharged.

Once the tip of the flat wire 30 rides over the inclined surface 2111 of the jig 210, the flat wire 30 can be continuously wound in the direction of the other end of the working core 41.

In this case, the flat wire 30, which moves along the guide groove 213 and is wound around the working core 41, remains perpendicular to the central axis Q of the working core 41 until it meets the inclined surface 2111 The flat wire 30 can be wound more tightly in the guide groove 213. [

The inlet 2136 of the guide groove 213 may have a tapered structure as shown in FIG. With such a tapered structure, the tip of the flat wire 30 can easily flow into the inlet 2136 of the guide groove 213.

Referring to Fig. 12, the coil generating mechanism 200 further includes a cover 230. Fig. The cover 230 prevents the flat wire 30 moving along the guide groove 213 from separating from the guide groove 213. 14 is a perspective view of the cover shown in Fig.

Referring to Figs. 12 and 14, the cover 230 includes a cover body 231 and a cover portion 233. [

The cover body 231 is disposed on one side of the jig 210 on which the guide groove 213 is formed and covers the guide groove 213. For example, the cover body 231 may initially be located far away from the guide groove 213, and may move toward the guide groove 213 before the flat wire 30 is wound on the coil member 40.

The cover body 231 is formed with a cover portion 233 which covers the guide groove 213. The cover portion 233 may have a thin plate shape, but is not limited thereto.

The cover portion 233 may have a shape corresponding to the guide groove 213. In one example, the cover portion 233 may have a straight region 2331 and a curved region 2332. The curved region 2332 of the cover portion 233 may have a concentric circle structure or the same curvature center with the curved region 2132 of the guide groove 213 or the working core 41. [

The cover body 231 is provided with a wall structure 232 extending in the Y-axis direction as viewed in FIG. 6, or in the thickness direction of the flat wire 30 in the longitudinal direction of the work core 41, May be formed.

The wall structure 232 may have the same shape as the guide groove 213. In one example, the wall structure 232 may have a straight region 2321 and a curved region 2322. The curved region 2322 of the wall structure 232 may have a concentric circle structure or the same curvature center with the curved region 2132 of the guide groove 213 and the working core 41.

When the cover portion 233 covers the guide groove 213, the flat wire 30 is wound around the work core 41 through the space formed between the wall structure 232 and the work core 41. [

An inclined plane 2333 is formed in the cover part 233 so that the tip end of the flat wire 30 rides over the flat wire 30 during the first rotation of the work core 41. Once the tip of the flat wire 30 rides over the inclined surface 2333 of the cover portion 233, the flat wire 30 passes through a space formed between the wall structure 232 and the working core 41, It can be continuously wound in the direction of the other end of the arm 41.

When the cover part 233 covers the guide groove 213, the tip end of the flat wire 30 once passes over the inclined surface 2111 formed on one side of the above-described seating groove 211, It is possible to pass over the formed inclined surface 2333 and be wound around the working core 41. [

Referring to Figs. 1 and 3, the flat wire-coil forming apparatus 10 further includes a cutting mechanism 400. Fig.

For example, when the flat wire 30 is wound on the work core 41 of the cores 41 and 42 of the coil member 40 by a predetermined amount, the operation of the flat wire feeding mechanism 300 is stopped.

Thereafter, the cutting mechanism 400 cuts a part of the flat wire 30 that has not flowed into the guide groove 213, thereby completing the primary winding for the working core 41. [ The coil generating mechanism 200 disposed close to the flat wire feeding mechanism 300 for winding the flat wire 30 may include a flat wire feeding mechanism 300 for securing a predetermined distance for cutting operation of the cutting mechanism 400, Lt; RTI ID = 0.0 > 300 < / RTI >

Thereafter, the coil member 40 is detached from the jig 210 and can be attached to the jig 210 again in the turned direction. At this time, the coil member 40 can be manually attached to and detached from the jig 210 by an operator. Or the coil member 40 may be detachably attached to the jig 210 automatically by a separate actuator (not shown).

When the coil member 40 is attached to the jig 210 in the redirection state, the secondary winding for the remaining core 42 of the coil member 40 is performed by the same process as the winding process for the working core 41 do.

On the other hand, the cutting mechanism 400 can cut the flat wire 30 in a linear shape. For example, the cutting mechanism 400 can cut the width Sb of the flat wire 30 into a straight line. For this, the cutting mechanism 400 may have a straight blade.

Or the cutting mechanism 400 may cut the flat wire 30 into a curved shape. For example, the cutting mechanism 400 may cut the width Sb of the flat wire 30 into a curved shape. To this end, the cutting mechanism 400 may have a curved blade.

In this regard, when the cutting mechanism 400 cuts the flat wire 30, the cut portion is cut by the rear end of the flat wire 30 wound on the operating coil 41 and the other end of the flat wire 30 ).

The cutting mechanism 400 may make the tip end of the wound flat wire 30 curved in the other coil 42. In this case, the tip of the flat wire 30 having a curved shape can smoothly pass through the guide groove 213.

Further, the cutting mechanism 400 may make the trailing end of the flat wire 30 wound on the operating coil 41 into a curved shape. For this purpose, the cutting mechanism 400 may have a structure in which the curved blade is reversible, or may have another blade in an inverted shape.

Referring to FIG. 9, the jig 210 may be provided with an interference prevention groove 214 for preventing interference of a coil. When the coil member 40 is inserted and supported in the seating groove 211 of the jig 210 for the secondary winding after the primary winding with respect to the coil member 40, (42) is reversed during the secondary winding. That is, the working core 41 in which the flat wire 30 is wound in the primary winding operation is disposed at the position where the remaining core 42 was present during the primary winding, and the remaining core 42, which is the object of the secondary winding, And is disposed at the position of the working core 41 at the time of the main winding.

If the interference preventing groove 214 is not formed in the jig 210, the work core 41 may be inserted into the seating groove 211 of the jig 210 for the secondary winding, There is a possibility that insertion of the coil member 40 into the seating groove 211 may not proceed smoothly because the primary winding coil 20 is interfered with the jig 210 or the seating groove 211.

In order to prevent this, an interference preventing groove 214 is formed in the jig 210. A part of the flat wire coil 20 wound on the working core 41 in the process of inserting the coil member 40 into the seating groove 211 of the jig 210 for the secondary winding is inserted into the interference preventing groove 214 So that the coil member 40 can be smoothly inserted into the seating groove 211.

15 is a view showing a coil generating mechanism according to another embodiment of the present invention.

Referring to Figs. 2 and 15, the coil generating mechanism 201 includes a jig 210, a cover 230, and a rotating roller 250. The rotary roller 250 is rotatably installed on the jig 210. The rotating roller 250 is rotated by driving means (not shown) such as a driving motor.

The rotary roller 250 rotates in contact with the width S B of the flat wire 30 moving along the guide groove 213. The rotary roller 250 pushes the flat wire 30 moving along the guide groove 213 in the moving direction of the flat wire 30.

In this case, in the process of moving the flat wire 30 along the guide groove 213, the stress caused by the friction with the inner side surface of the guide groove 213 can be reduced. The load of the flat wire feeding mechanism 300 for pushing the flat wire 30 toward the coil generating mechanism 201 is reduced.

The rotating roller 250 is preferably disposed at a position where the stress of the flat wire 30 can be minimized. For example, the rotary roller 250 may be positioned at a portion that changes from the linear region 2131 to the curved region 2132 of the guide groove 213 as shown in Fig.

The rotational speed of the rotating roller 250 can be controlled corresponding to the moving speed of the flat wire 30 moving along the guide groove 213. In this case, the stress caused by the friction with the inner surface of the guide groove 213 can be effectively reduced in the process of moving the flat wire 30 along the guide groove 213.

The rotation roller 250 can be rotated while being inserted into the roller groove 215 formed on one surface of the jig 210 in order to avoid interference with the cover 230. [

In FIG. 15, the coil generating mechanism 201 includes one rotating roller 250. This is merely an example, and a plurality of rotating rollers 250 may be provided.

For example, the coil generating mechanism 200 may include a plurality of rotating rollers 251, 252, and 253 as shown in FIG. 16 is a view showing a modification of the coil generating mechanism 201 of Fig. Referring to FIGS. 2 and 16, the rotary rollers 251, 252 and 253 are rotatably installed in the jig 210. The rotary rollers 251, 252, and 253 are disposed apart from each other along the guide groove 213.

The rotating rollers 251, 252 and 253 are rotated by a driving means (not shown) such as a driving motor. In one example, the driving force of the driving means may be transmitted to the rotating rollers by gears 261, 262, 263, 264, 265 intermeshing as shown in Fig. Alternatively, although not shown, the driving force of the driving means can be transmitted to the rotating rollers by the belt and the belt pulley.

For example, the rotating rollers 251, 252 and 253 can be located in the curved region 2132 of the guide groove 213, which can minimize the stress of the flat wire (30 in FIG. 1) have.

The coil generators 200, 201 and 202 as described above can effectively wind the flat wire 30 on the coil member 40 including the pair of cores 41 and 42 which are arranged in parallel and mutually connected to each other . The flat wire 30 can be tightly wound around the coil member 40 during the flat wire coil forming process.
