The height difference between the abutting portion 104a and the blade portion 1 is smaller than The wire diameter of the wire 4 is abutted against the flange portion 3a by the abutting portion 1〇4a, so that the lead wires (4a, 4b) can be notched by the blade portion i4b. Next, the sheet coil manufacturing device will be described. The operation of the chip coil manufacturing apparatus 1 is controlled by a controller (not shown) mounted on the chip coil manufacturing apparatus. 17 1326088 First, the winding step will be described with reference to FIG. The steps of aligning the leads (4a, 4b) with the electrodes 5. Figure 9 shows the winding step and the position alignment step in sequence. ^ The core support jig 21 is used in advance to support the core! The cylinder 26 of the core supporting mechanism 1 is driven, and the chuck member 24 is pressed by the piston 27 to support the core of the core supporting jig 21 Then, the flange portion 3b of the core portion 1 on which the electrode 5 is not formed is placed in the L-shaped portion U, and the pressing force caused by the piston 27 is released. Thereby, the elastic force of the elastic member 25 is received. The pressing portion 24a of the member 24 presses the flange portion against the L-shaped portion 23, and supports the core portion by the core supporting jig 21. The core portion 1 is supported by the core supporting jig 21 In the state, the flange portion 3a and the winding portion 2 on which the electrode 5 is formed are in a state in which the end portion of the core supporting jig 2 is protruded. The wire 4 supplied from the wire supply source (not shown) is inserted into the wire. The through-path 46 of the deforming mechanism 31 and the hollow portion of the cylindrical member 36 of the wire winding mechanism 3 are guided to the nozzle 6. The wire 4 sent from the nozzle 6 is held by the wire disposed at the upper portion of the nozzle 6. The wire member 4 between the chuck member 65 and the nozzle 6 is held by the head member 65 of the mechanism 60. The wire 4 is formed in the initial winding lead portion 4a, and is formed with a rectangular portion 7 which is deformed by a predetermined length. The winding operation of the core 丨 is started. First, the 3-axis moving mechanism 79 is driven to make the first base 34 and the first The base 64 is moved, so that the rotary shaft (central axis of the cylindrical member publication) of the nozzle 6 and the axial direction of the winding 2 of the core portion of the i _ actuator, and toward the nozzle 6 of this 18 i

Mi6〇88 The outer circumference of the winding unit 2 is moved (Fig. 9(B)). * The initial winding lead portion 4a of the wire 4 is climbed on the winding portion 2 to contact the inner wall of the canine portion 3b, and the nozzle rotary motor 4 is driven in this state. Thereby, the nozzle 6 is rotated around the winding portion 2, and the wire from the nozzle 6 is wound around the winding portion 2 (Fig. 9(C)). After the winding of the predetermined winding rent is completed, the winding operation is stopped, and the wire 4 of the predetermined length is deformed into a rectangular shape by driving the cam mechanism 47 of the wire deforming mechanism 31. Then, after the wire 4 is advanced by a predetermined distance, the winding operation is stopped, and the wire 4 of a predetermined length is again deformed into a rectangular shape. In this manner, the flat wires 8 and 9 are formed on the wires 4 with a predetermined interval therebetween. The winding operation is started again, and the first deformed flat-angled portion 8 is placed in the vicinity of the flange portion 3 & in which the electrode 5 is formed, and then the nozzle 6 is moved to engage the flat-angle portion 8 at the top of the flange portion 3a. Face 3d. At the same time as this operation, the chuck member 65 holding the initial winding lead portion 4a is moved so that the flat corner portion 7 of the initial winding lead portion 4a is also engaged with the top surface 3d of the flange portion 3& (D)). When the flat corner portions 7, 8 are engaged with the top surface of the flange portion 3a, the nozzle 6 and the chuck member 65 are moved away from the core portion i, respectively, and the wire 4 is straightened. It is easy to align the position of the flattened portions 7, 8 of the next action with the electrodes 5a' 5b. When the flat horns 7, 8 are engaged with the top surface of the flange portion 3a and are in a straight state, the upper and lower moving table a is moved downward by σ 80, and the nozzle 6 and the head are constructed. The lowering angles 7, 8 are bent along the flange portion 3a to be aligned with the electrodes 5a, 5b, respectively. Further, when 1326088 is not used for the straightening operation of the above-mentioned wire 4, the paint is knotted when the nozzle is lowered; and when the chuck member 6 5 is lowered, the (10) 4 is loosened and it is difficult to perform proper alignment. In this manner, the flat-angled pole-and-corner portion 8 of the initial wound lead portion 43 is aligned with the outside of the electrode, and the lead of the electric-shaped portion 8 constitutes the final wound lead portion. The I"-like leads (4a, 4b) are aligned with the position of the electrode 5, and the alignment is performed by the flattening of the lead, 8 . Compared with the round wire, the flat corner flange portion 3a is less prone to displacement. In the case of the pair of lead electrodes 5, the wire holding mechanism is formed during the process of lowering the chuck member 65 to make the flat corner portion 7 6〇之... 5 定机构...生... Refer to Figure 10==62 and tension and safety. Fig. 10(A) is a view showing the operation of the mm fixing mechanism 63 in which the tension relieving mechanism 62 operates. Fig. 1 (8) shows the tension when the initial winding lead portion 4a is engaged with the flange portion & Moved from the direction of (4)#65 toward (4)(4)i, the 'starting winding lead part...the force becomes large, and the kind of conditional tensioning mechanism is set to 'as shown in Fig. H) (8). The piston 72 is accommodated in the cylinder 71 to make the chuck The member 65 can be rocked about the axis. Further, when the driving medium in the gas red η is discharged to allow the piston 72 to freely slide in the cylinder 71, the chuck member 65 also becomes rockable. By performing the above arrangement, when the chuck member 65 is moved away from the core portion, the tension of the winding lead portion becomes large during the lowering process, and the chuck member 65 is shaken to suppress the initial roll. Ten 20 1326088 force around the lead portion. Therefore, it is possible to prevent the tension of the initial winding lead portion 4a from being excessively large. As shown in Fig. 10(B), the chuck member 65 is further lowered, and the initial winding lead portion 4a is brought into contact with the tension maintaining mechanism 63. The curved surface 75a of the lead member 75 is guided by the party. In this manner, when the initial winding lead portion 4a is guided by the guiding member 75, the cylinder 71 of the tension relieving mechanism 62 is actuated to hold the rear end portion of the chuck member 65 with the piston 72 and the holding plate 63. Thereby, the chuck member 65 is fixed so as not to be shaken.

In a state where the initial winding lead portion 4a is guided by the guiding member 75, when the tension of the initial winding lead portion 4a is changed, the tension change is caused by the spiral between the guiding member 75 and the chuck member 65. The spring % is absorbed. When the initial winding lead portion 4a is to be aligned with the electrode 5, the tension of the initial winding lead portion can be stabilized by the action of the tension maintaining mechanism 63.

Next, the step of joining the flat-angled portion 5 of the lead-wound portion 4a and the flat-angled portion 8 of the final wound lead portion 4b to the (four) electrode 5a and the electrode 5b will be described with reference to Fig. 11 . Figure u shows the wire bonding step in sequential order. From the state in which the bow 1 line (4a, 4b) of Fig. 9 (8) is aligned with the electrode 5, the nozzle 6 and the chuck member 65 are further lowered. At this time, in the core bitterness, one of the main open states is hanged, and the lead of both sides is lowered by the open portion of the holder 28 (Fig. U(A)). By lowering the nozzle 6, such as a cabinet, ^ as shown in Fig. 1 (8), the flat-angled portion 9 is sent out by the nozzle 6 (a barrier is placed through the predetermined question), and a flat-angled portion g, 9 is disposed. Late deformed). hold. The opened woman H (four) is combined, and the material is fixed and held to hold the holder 28 of the final winding lead portion, and the system 21 1326088 fixes and holds the flat angle portions 8 and 9 together (Fig. The kidney of the chuck member 65 4a i±4 ^ + the pressing plate 66 pairs the initial winding lead. The 丨 4a is refreshed. After that, the chuck structure is moved to the 4th eve + 4* ® 65 movement, and will eventually The holder 28 for winding the lead wire 4b is held relatively (Fig. 11(C)). Between the horns 9 and the horns 9, the final winding of the chuck member 65 is carried out, and the chuck member 65* nozzle 6 is returned to the initial position of the winding step. By this operation, the final winding lead portion 4b is cut (10), and the chuck member 65 holds the preliminary lead wire 4, and becomes the next waiting. Carry out ', the initial winding of the core 1 of the twisted line Μ μ α 1 , a. That is, the two flat angles (4) 8 and 9 which are deformed by the wire, the later deformed flat angle The 9-series is a flat-angled portion of the initial winding lead portion. "When the final winding lead portion 4b is cut, the indexing is rotated. The table 13 is completed to complete the k-line step. Opposite the core after the alignment step. 1 1 Xinggong 丨 line joining mechanism 12 phase: heating heating device 96 forward 'with its protrusion... will start the winding 8 8 horns 7 and the final roll The flat-angled portion 8 around the lead portion 4b is pressed against the electrodes 5a and 5b (Fig. 11(E)). Since the flat-angled portions 7, 8 are deformed, the film is covered by the flat-angled portions 7, 8 and the edge film is thinned. Moreover, due to the flat-angle deformation, the thickness-changing heating device 96 can be closer to the solder, and the heat of the heating device is more likely to be transmitted, so that the heating device 96 can more easily make the flat-angled portions 7, 8 absolutely rupture, and The solder on the surface of the electrode 5 is melted. Thereby, as shown in Fig. i2(a), the side portions of the flat-angled portions 7, 8 can be joined to the electric 22 pole 5 through the solder 107. The flat horn portion 7, 8 @ τ The thickness of the round wire shown in 12(9) is thinner, so the thickness of the wire is reduced compared with the figure. The 'moon shape' can reduce the decrease of the amount of the solder of the solder 107 filled with the solder on the side portion, leaving a larger amount The connection area at the time of connection thus ensures that other electronic components and electrodes 5 are subsequently described with reference to FIG. 8 and FIG. The movable Φ member of the structure 103 swayes the movement of the tool 1〇4, and FIG. 13 shows the wire pressing. After the step 0, as shown in FIG. 8, the tool 104 disposed at the lower portion of the wire bonding 12 is advanced. The abutting portion 1 is cut between the start A, the lead portion 乜, and the final wound lead portion 4b to abut against the flange. The lower portion of the electrode 5 of the outer side surface 3c is used. The portion _ is formed in the initial winding lead portion 4a and the final winding lead portion 4b to form a notch 1"". The cutter 104 of the notched operation is retracted and returned to the original position. Next, as shown in FIG. 13, the wire pressing member 1G5 disposed at the lower portion of the tool 1〇4 is pushed in, and the initial winding lead portion 4a and the final winding lead portion are notched 1〇6 and the holding The device 28 is pressed between them. Thereby, the tension between the notch 106 and the holder 28 is increased, and the force is concentrated on the notch ^(10), and the initial winding lead portion 4a and the final winding lead portion are cut by the notch 106. Further, the method of increasing the tension between the initial winding lead portion 4a and the notch 106 of the final winding lead portion 4b and the holder 28 can also move the heart palpe 1 and the holder 28 relatively. get on. At this time, it is not necessary to provide the guide member 13 1326088. Conventionally, in order to cut the lead wire, it is necessary to pull the lead wire to the end portion of the flange portion and pull it with force, so that the flange portion may be damaged. However, the method of cutting the lead wire by the wire cutting mechanism 103 is to form the notch 1〇6 in the lead, and then cut the lead in the force m in the absence of 1〇6❿, so that it is not necessary to use too much force when cutting. 'This prevents the breakage of the flange portion 3. In this manner, the sheet-like coil is manufactured by the sheet-like coil manufacturing apparatus 100. The lead of the chip coil produced by the chip coil manufacturing apparatus 10 has a rectangular shape, so that the size of the chip coil can be reduced. Thus, the size of the chip coil can be controlled within a desired range. According to the first embodiment described above, the following effects can be achieved. When the wire is bonded to the electrode 5, the wire 4 is first formed into a rectangular shape, and the flat portion is heated and pressed against the electrode 5, so that it is not required to be pressed against the electrode 5 as in the case of the conventional round wire. . Therefore, the possibility of breakage of the electrode 3 and the flange portion 5 can be reduced, and a sheet-like coil in which the lead wire and the electrode 5 are in a stable state can be obtained. The alignment of the lead and the electrode 5 is performed by engaging the flat corner portions 7, 8 of the lead wire with the flange portion 3. Compared with the round wire, the flat horns 7, 8 are more likely to be displaced on the flange portion 3 and are more stable. Therefore, the lead can be correctly aligned with the electrode 5. Further, since the lead to be bonded to the electrode 5 has a flat angle, the amount of solder attached to the lead is reduced as compared with the case of the circular lead. Therefore, a large solder fillet can be left, which ensures the connection area when other electronic components are subsequently connected to the electrode 5. Further, the electrodes 5a and 5b corresponding to the initial winding lead portion 4a and the final winding lead portion 4b are formed in parallel on the outer side surface 3c of the flange portion 3 of the core portion i. Therefore, both the initial winding lead portion 4a and the electrode 5, and the joining of the initial winding lead portion 4b and the electrode 5 can be simultaneously performed, so that the sheet-like coil can be efficiently manufactured. (Second Embodiment) Next, a sheet-like coil manufacturing apparatus 200 according to a second embodiment of the present invention will be described with reference to Figs. 14 and 15 . Fig. U shows a perspective view of the chip coil manufacturing apparatus 2''; Fig. 15 shows the winding step and the positional alignment in a sequential order. The chip coil manufacturing apparatus 200 differs from the chip coil manufacturing apparatus 100 of the first embodiment in that the timing at which the wire 4 is deformed into a rectangular shape is different. In the following description, the same components as those of the chip-coil manufacturing apparatus 100 will be described with the same reference numerals and will not be described. In the chip coil manufacturing apparatus 100, the wire deforming mechanism 31 is disposed on the first base 34, and the wire 4 is deformed into a rectangular shape by the wire deforming mechanism 31 before being introduced into the nozzle 6. On the other hand, as shown in FIG. 14, the sheet-like coil manufacturing apparatus 2 is provided with a wire deforming mechanism 2〇1 instead of the wire deforming mechanism 31, and is disposed on the base 2 W and opposed to the winding mechanism u. The manner is disposed in the vicinity of the core support mechanism 10. The wire deforming mechanism 2G1 includes a deformation pressing mechanism 202 that deforms the wire portion into a flat shape, and a guiding mechanism 203 that guides the pressing mechanism 2〇2 to the wire 4. The pressing mechanism 202 is provided with a pair of pressing plates 205a and 205b which are supported by the supporting members 2〇4. The pair of pressing plates 2〇5a and 2〇5b are slidably engaged with a rail (not shown) provided on the inner peripheral bottom surface of the support member 204, and are driven by a driving member (not shown) such as an air cylinder. Can move in the direction of approaching each other. The wire 4 is pressed and pressed by a pair of pressing plates 2〇5a and 2〇5b to form a rectangular shape. Here, the rail provided on the inner peripheral bottom surface of the support member 204 is preferably arranged in parallel with the axial direction of the winding portion 2 of the core portion 1. Preferably, the pair of pressing plates 2〇5&, 2〇5b' are arranged such that the pressing faces of the holding wires 4 are arranged with the core portion! The flange portions 3a are parallel. By arranging the rails and the pair of pressing plates 2〇5a, 2〇5b' in such a manner, the deformed wires 2〇5a, 2(4) are applied to the deformed wires*, and the flattened portions are formed to be formed with the flange portion 3a. The surface of the electrode 5 is parallel, so that the subsequent bonding of the wire 4 to the electrode 5 becomes easy. The motor 207 of the moving mechanism 21 0 is coupled to the ball screw 208

The guiding mechanism 203 includes a pair of moving mechanisms 21, and includes a frame 206, a ball screw 2〇8 attached to the output shaft of the motor 207 at the end of the frame 2〇6, and a moving table 209 screwed together. The moving mechanism 2 1 〇 is horizontal g; » is and 43⁄4 1 / main 80 is disposed on the base 14, and the other moving mechanism 210 is disposed in the wrong direction. The movements 209 of each other are coupled via a joint member, and the support member 2G4 is coupled to the mobile station 209 of the other-moving mechanism 21A. Thereby, the supporting member 鸠' can be moved in both directions in the horizontal direction and the slanting direction. 26 1326088 One of the moving mechanisms 21A on the base plate 14 is arranged such that the ball shaft 2〇8 extends in a direction orthogonal to the axial direction of the winding portion 2 of the anger portion 1. Next, the step of winding the sheet-like coil manufacturing apparatus 200 and the step of aligning the leads 4a and 4b with the electrode 5 will be described with reference to Fig. 5 . The preparation work for winding the core portion 1 is different from the above-described i-th embodiment, "the approximate phase of the two is as shown in Fig. 15 (A), at the start of winding, at the beginning of winding the lead The flat portion is not formed in the portion 4a. First, the three-axis moving mechanism 79 is driven to match the axis of rotation of the nozzle 6 with the axial direction of the winding portion 2 of the first nozzle, and the nozzle 6 is moved toward the outer periphery of the portion 2 of the core portion (Fig. 15(b)). % Next, by driving the nozzle to rotate the motor 4〇, the wire 4 is wound on the roll 4 by a number resistance. In this state, the driving guide mechanism 203 moves the pressing mechanism 202 to be tight. The mechanism 2〇2 is positioned such that the initial winding portion is located between the pair of pressing plates 2〇5a and (4). Next, as shown in Fig. i5 (c: the hunting member moves the pair of tight ink plates and the cymbals toward each other) And the winding wire is initially wound to be pressed. Thereby, the flat corner portion 7 is formed at the beginning 2 ^ portion. When the lead portion = the flat corner portion 7 is wound at the beginning, the mechanisms 2 () 2 are caused. Then, as shown in Fig. 15 (9), the nozzle 6 is moved to the outside of the electrode and extends from the nozzle 6 to the winding portion = the final winding lead portion 4b. The pile base Λ The m joint drive drive mechanism 203 again, and the flat portion is also formed in the final floor (4) line portion 4b by the hot-boiler mechanism 202. The flat portion is formed in the final winding lead portion 4b. When it is retracted, the W-angle portion 8 is removed. After the 'tightening mechanism 2 〇 2 27 1326088 ..., as shown in Fig. 15 (E), both the starting winding lead portion guttata member 65 and the nozzle 6 are held to move the leading winding portion 钧The flat corner portion 7 and the topmost vibrating can are engaged with the top surface 3d of the flange portion 3a, and the flat corner portion 8 of the line portion 4b is engaged with the lower moving platform as shown in Fig. 15(F). Moving to the side, the mouthpiece 6 and the head member 65 are lowered together, and the flat-angled portions 7, 8 are bent along the flange portion 3a to align the electrodes 5a, 5b, respectively. The flattened portion 7 of 4a is aligned with the electrode 5a, 'the flattened portion 8 of the final wound lead portion 4b is aligned with the electrode. The subsequent flattened portions 7, 8 are joined to the electrodes 5a, 5b, respectively, due to Since the above-described embodiment i is the same, the description thereof will be omitted. In the above description, the formation of the flat-angled portion 7 in the initial winding lead portion = is performed by winding the number resistance in the winding portion 2. After the wire 4 is carried out, the operation of forming the flat-angled portion 8 at the final winding lead portion 4b can also be performed at the same time-point. When the winding portion 2 is wound around a predetermined number of windings, the initial winding is performed. The lead wire Ma and the final winding lead portion 4b are sequentially formed into the flat-angled portions 7, 8. The above description "in the chip-shaped coil manufacturing apparatus 2", the formation of the second-rolling lead portion 4a and the final winding lead portion # The flat-angled portions 7, 8 are formed in the vicinity of the electrodes 5a, 5b at the point where the flat-angled portions 7, 8 are aligned with the electrodes 5&, ^, that is, the initial winding is led. And finally, the lead portion 4b is guided to the electrode 5a and the plurality of flat portions 7, 8. According to the second embodiment described above, the sheet-like coil manufactured by the manufacturing apparatus and the manufacturing method of the present invention described below 28 can be used mainly for a small-sized electronic device, and a small core may be used. Department] and extremely thin wire 4. At this time, before the winding of the wire 4 (before leading to the electrode 5), the method of forming the wire 4 into a rectangular portion 7, 8 in advance may be in the flat portion 7 of the wire 4, 8 produces a broken line. Further, since the electrode 5 on the core portion 1 is extremely small, it is difficult to accurately align the previously formed flat-angle portions 7, 8 to the electrode 5. However, in the >5 I coil manufacturing device 2, the initial winding lead portion 4a and the final winding lead portion are guided to the electrode core, and the flat angles 4, 7 and 8 are formed. The winding operation of the wire 4 is performed only after the flat horns 7 and 8 are formed. Therefore, since the flat horns 7, 8 are not required to be bent straight, they do not form a flat angle. The disconnection of p 7 and 8 is able to correctly align the flat portions 7, 8 with the electrodes 5a, 5b even if the electric #5 is very small. The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the technical idea. The present invention is applicable to a sheet coil manufacturing apparatus.
