Description

Technical Field

[0001] The present invention relates to a conductive wire insulation film stripping device, a winding device equipped with the conductive wire insulation film stripping device, and a conductive wire winding method. Background Art

[0002] At present, an insulating film is formed on the outer surface of the conductive wire used in electronic parts and the like. When welding or soldering such a conductive wire with an insulating film to a terminal or a guide wire, welding or soldering is performed after each stripping of the insulating film. As a method for effectively performing the stripping operation of the insulating film, there is known a method in which a device for stripping the insulating film is provided in a supply path of the conductive wire, and the insulating film of the conductive wire being supplied is stripped at a necessary time.

[0003] As such a peeling device, there is known a peeling device comprising: a rotating part driven by a motor, a swing arm pivotally supported on the rotating part in a freely swinging manner through a pin, a hammer provided on one end side of the swing arm, a knife and a friction part provided on the other end, and a force applying unit for applying force to the swing arm in a direction in which the knife is put into a standby state (for example, refer to Japanese Patent Laid-Open JPH10-322833A).

[0004] In this stripping device, the rotating component rotates by the rotation of the motor, causing the hammer to generate centrifugal force, causing the swing arm to swing in a manner to overcome the force of the force-applying unit, causing the knife provided at the other end of the arm to bite into the film of the conductive wire, and in this state, the knife is moved a predetermined length in the long side direction of the conductive wire, thereby being able to remove a predetermined length of the film corresponding to the movement amount of the knife. Summary of the invention

[0005] However, in a stripping device that removes the insulating film on the outer surface of a conductive wire by moving a cutter in the long side direction of the conductive wire while the cutter is pressed against the outer surface of the conductive wire, there is an undesirable problem that the finishing is different between an initial stripping portion where the cutter first contacts the conductive wire and an end stripping portion where the cutter is separated from the conductive wire after moving a predetermined length.

[0006] Specifically, although the insulating film of the conductive wire is stripped off by moving the blade in contact with the outer surface of the conductive wire in the long side direction, the stripped insulating film is reliably removed by the moving blade at the initial stripping position where the blade first contacts, and therefore, no insulating film remains at the initial stripping position.

[0007] However, since a portion of the stripped insulating film is in close contact with the cutter and moves with the cutter, at the end of stripping where the cutter is separated from the conductive wire, a portion of the stripped insulating film that has moved with the cutter may remain on the surface of the conductive wire as stripping residue.

[0008] In addition, such a stripping device is also used in a winding machine that winds a conductive wire around a wound component. The conductive wire wound around the wound component is stripped of its insulating film by the stripping device at both the winding start position on the top end side and the winding end position on the base end side, and is welded to a terminal and a guide wire provided on the wound component.

[0009] However, in a winding machine using a conventional stripping device, the direction of removing the insulating film by the blade is set in advance to be either from the base end side to the tip side or from the tip side to the base end side of the conductive wire, so stripping residue may remain at either the winding start position or the winding end position of the conductive wire wound on the wound portion. Since the stripping residue composed of the insulating film has insulating properties, when the stripping residue remains at the stripping position welded on the terminal and the guide wire, a defect such as poor connection may occur.

[0010] In order to avoid this phenomenon, conventionally, when peeling residue is generated, an operator pushes a felt or the like against the conductive wire to scrape off the peeling residue, but this operation increases the operator's man-hours.

[0011] An object of the present invention is to provide a conductive wire insulation coating stripping device capable of changing the direction in which a stripping residue is generated.

[0012] Another object of the present invention is to provide a winding device and a winding method in which no peeling residue remains on a peeling portion of a conductive wire.

[0013] According to one embodiment of the present invention, a conductive wire insulating film stripping device for stripping the insulating film of a conductive wire comprises: a first stripping machine, which strips the insulating film of the conductive wire by moving a first knife piece pushed around the conductive wire to the top end side of the conductive wire; a second stripping machine, which is arranged adjacent to the first stripping machine, and strips the insulating film of the conductive wire by moving a second knife piece pushed around the conductive wire to the base end side of the conductive wire; and a stripping machine moving unit, which moves either or both of the first stripping machine and the second stripping machine along the long side direction of the conductive wire.

[0014] According to another embodiment of the present invention, the winding device comprises: a conductive wire insulation film stripping device; a wire unwinding unit, which unwinds the conductive wire into the conductive wire insulation film stripping device with a predetermined tension; and a winding unit, which winds the conductive wire that has passed through the conductive wire insulation film stripping device around a wound component.

[0015] According to another aspect of the present invention, a conductive wire winding method for winding a conductive wire around a wound component comprises: a winding initial stripping step, in which a first knife piece pushed around the conductive wire is moved to the top end side of the conductive wire, thereby stripping off a predetermined length of the insulating film of the conductive wire whose top end is clamped at a clamping portion, thereby forming a winding initial stripping portion; a winding initial clamping step, in which the winding initial stripping portion is clamped at a winding initial connecting portion of the wound component; a winding initial cutting step, in which the conductive wire between the winding initial connecting portion and the clamping portion is cut near the winding initial connecting portion; a winding step, in which the conductive wire is continuously connected to the winding initial stripping portion. The conductive wire is wound around the wound component; a winding end stripping process, which is to move the second knife piece pushed around the conductive wire to the base end side of the conductive wire, thereby stripping the insulating film of the winding end portion of the conductive wire by a predetermined length, thereby forming a winding end stripping portion; a winding end locking process, which is to lock the winding end stripping portion to the winding end connection portion of the wound component; a temporary fixing process, which is to lock the conductive wire extending from the winding end connection portion to the base end side to the locking portion; a winding end cutting process, which is to cut the conductive wire between the winding end connection portion and the locking portion near the winding end connection portion.

[0036] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0037] exist Figure 1 , a conductive wire insulation film stripping device 10 of the present embodiment is shown. The conductive wire insulation film stripping device 10 (hereinafter referred to as "stripping device 10") comprises: a top end facing stripping device 11 as a first stripping device and a base end facing stripping device 21 as a second stripping device, the top end facing stripping device 11 and the base end facing stripping device 21 being symmetrical structures; and a stripping device moving unit 31, which moves either or both of the top end facing stripping device 11 and the base end facing stripping device 21 along the long side direction of the conductive wire 8.

[0038] The top end of the stripping machine 11 has a rotating member 12 as a first rotating member that is arranged to be rotatable around the conductive wire 8. The rotating member 12 is a tubular body formed by passing through an insertion hole, and the insertion hole can be inserted through the conductive wire 8. A large-diameter flange 12a with a relatively large outer diameter is formed in the approximately central portion in the long-side direction of the rotating member 12. In addition, a small-diameter flange 12b with a smaller diameter than the large-diameter flange 12a is formed in a portion of the rotating member 12 that is close to the base end and faces the stripping machine 21, with a predetermined interval between the large-diameter flange 12a and the large-diameter flange 12a and approximately parallel to each other.

[0039] A plurality of cutter shafts 13 as first cutter shafts are provided on the two flanges 12a and 12b integrally formed on the rotating member 12 so as to straddle the two flanges 12a and 12b. The plurality of cutter shafts 13 are inserted into holes formed on the two flanges 12a and 12b and penetrate the two flanges 12a and 12b in the long side direction of the conductive wire 8. The plurality of cutter shafts 13 are supported by the rotating member 12 so as to be rotatable around the axis thereof.

[0040] like Figures 2 to 4 As shown, three blade shafts 13 are arranged at intervals of 120° with the rotation axis of the rotating member 12 as the center. The plurality of blade shafts 13 are arranged along the long side direction of the rotating member 12 and are arranged at equal intervals around the central axis of the rotating member 12. Figure 1As shown, the plurality of tool shafts 13 are arranged obliquely in a manner that the mounting radius becomes larger on the side of the large diameter flange 12a than the small diameter flange 12b relative to the rotating member 12. In other words, the tool shaft 13 is arranged obliquely in a manner that the top end side where the tool 14 described later is arranged is located near the conductive wire 8 compared to the rear end side where the hammer 15 described later is arranged.

[0041] like Figures 1 to 3 As shown, a blade 14 as a first blade is fixed to the end portion, i.e., the top end portion, of the plurality of blade shafts 13 on the side of the small-diameter flange 12b so as to surround the conductive wire 8. The blade 14 is configured to be able to make contact and separate with respect to the conductive wire 8 extending from the end edge of the rotating member 12 on the side of the small-diameter flange 12b according to the rotation of the blade shaft 13.

[0042] like Figure 1 As shown, the end of the rotating component 12 on the side of the large diameter flange 12a provided with a plurality of knife shafts 13 is supported by the support plate 16 through the bearing 16a so as to be able to rotate freely. The driving device, i.e., the motor 17, is mounted on the support plate 16 in such a manner that its rotating shaft 17a is parallel to the rotating component 12. In addition, a pulley 12c is fixed to the end of the rotating component 12 on the opposite side of the large diameter flange 12a across the support plate 16. A pulley 17b is also provided on the rotating shaft 17a of the motor 17, and a belt 17c is provided between the pulley 17b and the pulley 12c. Therefore, the rotational motion of the rotating shaft 17a of the motor 17 is transmitted to the rotating component 12 via the belt 17c. In this way, the rotating component 12 is rotationally driven by the motor 17.

[0043] When the rotating member 12 is driven to rotate, the flanges 12a, 12b and the rotating member 12 rotate together with the conductive wire 8 as the center, and the plurality of tool shafts 13 also revolve around the conductive wire 8 together with the flanges 12a, 13b.

[0044] like Figures 1 to 3 As shown in FIG. 1 , a hammer 15 as a first hammer is provided at the end portion of each cutter shaft 13 near the large diameter flange 12a, i.e., the rear end portion. The hammer 15 is fixed in a state where the center of gravity is eccentric with respect to the axis of the cutter shaft 13 in the circumferential direction of the large diameter flange 12a. Figure 3 As shown in the figure, when the plurality of cutter shafts 13 revolve around the conductive wire 8 as the center, as shown by the dotted arrow, the centrifugal force F acts on the hammer 15 provided at the rear end of the cutter shaft 13, and the portion of the hammer 15 away from the cutter shaft 13 moves radially outward. When the cutter shaft 13 rotates with the displacement of the hammer 15, the blade 14a of the cutter 14 provided at the top end of the cutter shaft 13 approaches the conductive wire 8 and contacts the conductive wire 8.

[0045] like Figure 1 As shown, the blade 14 is in contact with the side of the conductive wire 8 inserted into the rotating member 12 and extending from the end edge on the side of the small-diameter flange 12b. Therefore, when the blade shaft 13 is rotated with the rotating member 12 with the conductive wire 8 as the center, and the blade 14a in contact with the conductive wire 8 is moved along the conductive wire 8 toward the side of the large-diameter flange 12a, the blade 14a of the blade 14 in contact with the conductive wire 8 peels off the coating of the conductive wire 8 in a spiral shape.

[0046] In addition, a leaf spring 18 is provided on the top end toward the stripping machine 11, and the leaf spring 18 urges the knife shaft 13 in a direction to separate the knife 14 from the conductive wire 8 in a manner to resist the centrifugal force F acting on the hammer 15. A mounting ring 19 for fixing the leaf spring 18 to the rotating member 12 is mounted on the rotating member 12 on the side of the support plate 16 relative to the large-diameter flange 12a by mounting screws 19a. The base end of the leaf spring 19 is mounted on the mounting ring 19 by fixing screws 18a.

[0047] On the other hand, a pin 15a is provided on the hammer 15 in parallel with the cutter shaft 13. The pin 15a is attached to the hammer 15 on the radially outer side of the rotating member 12 relative to the cutter shaft 13. Figure 4 As shown, the leaf spring 18 is attached to the mounting ring 19 at its base end in a bent state so that its top end or middle portion abuts against the pin 15 a .

[0048] The elastic force of the leaf spring 18, whose tip or middle portion contacts the pin 15a in a bent state, urges the weight 15 via the pin 15a in a direction opposite to the direction in which the weight 15 is displaced by the centrifugal force. Figure 1 as well as Figure 4 Reference numeral 19b denotes a disk 19b having a guide groove for guiding the pin 15a. The disk 19b is provided to make the displacements of the hammers 15 in the radial direction of the rotating member 12 uniform, that is, to make the rotation amounts of the plurality of tool shafts 13 uniform.

[0049] Since the leaf spring 18 is provided in this way, when the rotation of the rotating member 12 stops, the knife shaft 13 rotating according to the centrifugal force rotates in the opposite direction due to the elastic force of the leaf spring 18, as shown in FIG. Figure 2 As shown in FIG. 1 , the blade 14a of the knife 14 is in a state separated from the conductive wire 8, that is, in an initial state. In this state, the conductive wire 8 can be moved in the longitudinal direction without peeling off the film of the conductive wire 8. Figure 2 as well as Figure 3The symbol 12d in the figure indicates a notch 12d for limiting the movement of the pin 15a. When the blade 14a is separated from the conductive wire 8, the notch 12d abuts against the pin 15a, thereby limiting the amount of rotation of the knife shaft 13 in the reverse direction by the leaf spring 18.

[0050] The top end facing stripping machine 11 is constructed as described above, such as Figure 1 As shown, the base-end-facing peeling machine 21 has a structure symmetrical to the top-end-facing peeling machine 11, and is provided adjacent to the top-end-facing peeling machine 11. The base-end-facing peeling machine 21 has a structure symmetrical to the top-end-facing peeling machine 11, and the structure of each part is the same as that of the top-end-facing peeling machine 11, so the description of each part of the base-end-facing peeling machine 21 is omitted. The symbols of the parts of the base-end-facing peeling machine 21 corresponding to the top-end-facing peeling machine 11 are expressed as parts obtained by adding 10 to the symbols of the corresponding parts of the top-end-facing peeling machine 11, for example, the symbol of the rotating part of the base-end-facing peeling machine 21 is 22.

[0051] The base-end-oriented peeling machine 21 is arranged in a state where the blade 24 as the second blade provided at the tip of the blade shaft 23 as the second blade shaft is opposed to the blade 14 of the tip-oriented peeling machine 11, and each peeling machine 11, 21 is mounted on a square-shaped table 30 through each support plate 16, 26 in a manner such that the rotation centers of the respective rotating members 12, 22 are coaxial. In this way, the base-end-oriented peeling machine 21 is arranged adjacent to the tip-oriented peeling machine 11.

[0052] The stripper moving unit 31 moves both the top end toward the stripper 11 and the base end toward the stripper 21 along the long side direction of the conductive wire 8. The stripper moving unit 31 includes: an elongated box-shaped housing 31d extending in the long side direction of each coaxially arranged rotating member 12, 22; a ball screw 31b provided inside the housing 31d so as to extend in the long side direction and rotationally driven by a servo motor 31a; and a follower 31c screwed with the ball screw 31b and moving along the ball screw 31b.

[0053] The platen 30 to which the peeling machines 11 and 21 are attached is attached to the follower 31 c so that the rotation center of each rotating member 12 and 22 and the rotation center of the ball screw 31 b are parallel.

[0054] The servo motor 31a is driven by a command from a controller (not shown), and when the ball screw 31b rotates, the follower 31c screwed with the ball screw 31b moves in the long side direction of the housing 31d together with the platen 30 and the strippers 11 and 21. In this way, the strippers 11 and 21 can be moved along the long side direction of the conductive wire 8 while the conductive wire 8 is inserted through the rotating members 12 and 22.

[0055] Next, refer to Figure 5 to Figure 7 , a winding device 50 including the peeling device 10 having the above structure is described. Hereinafter, the structure of the winding device 50 is described by setting three axes X, Y, and Z that are orthogonal to each other, and the X axis extends in a substantially horizontal front-to-back direction, the Y axis extends in a substantially horizontal lateral direction, and the Z axis extends in a substantially vertical direction.

[0056] The winding device 50 includes a wire unwinding unit 51 for unwinding the conductive wire 8 toward the stripping device 10 at a predetermined tension. Figure 6 As shown, the conductive wire 8 is wound and stored on a bobbin 52. The conductive wire 8 unwound from the bobbin 52 is guided toward the stripping device 10, and a tension device 53 for applying a certain tension to the conductive wire 8 is provided in the middle.

[0057] The tension device 53 applies tension to the unwound conductive wire 8 to pull back the conductive wire 8 , and includes a housing 54 disposed on the stand 50 a and a tension rod 56 disposed on a side surface of the housing 54 so as to extend in the vertical direction.

[0058] The bobbin 52 on which the conductive wire 8 is wound is arranged on the side of the housing 54, and a reeling control motor 57 for rotating the bobbin 52 to reel out the conductive wire 8 is arranged inside the housing 54. In addition, a guide pulley 58 for guiding the conductive wire 8 unwound from the bobbin 52 is arranged at the top end of the tension rod 56, and the conductive wire 8 unwound from the bobbin 52 is wired to the stripping device 10 via the guide pulley 58.

[0059] The tension rod 56 can rotate in the XZ plane, that is, in a plane parallel to the side surface of the housing 54 on which the tension rod 56 is provided, with the rotation shaft 56a at the base end as a fulcrum. The rotation angle of the rotation shaft 56a is detected by a potentiometer 59 as a rotation angle detection unit accommodated in the housing 54 and mounted on the rotation shaft 56a. The detection output of the potentiometer 59 is input by a controller (not shown), and a control signal corresponding to the detection output of the potentiometer 59 is output from the controller to the unwinding control motor 57.

[0060] In addition, at a predetermined position between the rotation shaft 56a of the tension rod 56 and the guide pulley 58, one end of a spring 61 as a force-applying unit for applying a force in the rotation direction of the tension rod 56 is installed through a mounting bracket 56b. The other end of the spring 61 is fixed to a moving part 62 provided on the housing 54. Therefore, the spring 61 applies a force to the tension rod 56 by an elastic force generated according to the rotation angle of the tension rod 56. The moving part 62 is screwed with the tension adjustment screw 63 and can move in the X-axis direction according to the rotation of the tension adjustment screw 63. In this way, by changing the fixed position of the other end of the spring 61 and adjusting the force applied to the tension rod 56 from the spring 61, the tension applied to the conductive wire 8 from the tension rod 56 can be adjusted.

[0061] The controller (not shown) controls the unwinding control motor 57 so that the rotation angle detected by the rotation angle detection unit, that is, the potentiometer 59, becomes a predetermined angle. That is, in the tension device 53, the bobbin 52 is rotated so that the rotation angle of the tension rod 56 becomes a predetermined angle, thereby setting the tension applied to the conductive wire 8 from the spring 61 via the tension rod 56 to be constant, and unwinding a predetermined amount of the conductive wire 8. The conductive wire 8 to which the predetermined magnitude of tension is applied is unwound toward the stripping device 10 in a state where the tension is applied.

[0062] The winding device 50 includes a nozzle moving unit 66 that moves a support plate 65 on which the peeling device 10 is installed in three axial directions.

[0063] like Figure 5 as well as Figure 6 As shown, the nozzle moving unit 66 is composed of a combination of telescopic actuators 67 to 69 in the X-axis, Y-axis, and Z-axis directions. Each telescopic actuator 67 to 69 constituting the nozzle moving unit 66 includes: an elongated box-shaped housing 67d to 69d; ball screws 67b to 69b, which are arranged inside the housing 67d to 69d in a manner extending in the long-side direction and are rotationally driven by servo motors 67a to 69a; and driven members 67c to 69c, which are screwed with the ball screws 67b to 69b and move along the ball screws 67b to 69b.

[0064] The nozzle moving unit 66 is configured to enable the support plate 65 to move in three-axis directions relative to the gantry 50a. In order to enable the support plate 65 to move in the X-axis direction, the support plate 65 is attached to the housing 67d of the X-axis telescopic actuator 67 via the vertical plate 65a. In addition, in order to enable the support plate 65 to move in the Z-axis direction together with the X-axis telescopic actuator 67, the follower 67c of the X-axis telescopic actuator 67 is attached to the follower 69c of the Z-axis telescopic actuator 69.

[0065] In addition, in order to enable the support plate 65 to move in the Y-axis direction together with the X-axis and Z-axis telescopic actuators 67 and 69, the housing 69d of the Z-axis telescopic actuator 69 is attached to the follower 68c of the Y-axis telescopic actuator 68. The housing 68d of the Y-axis telescopic actuator 68 is fixed to the stand 50a in a state along the Y-axis direction. The servomotors 67a to 69a of the telescopic actuators 67 to 69 are connected to a controller (not shown) that controls them.

[0066] On the support plate 65, the housing 31d of the stripping machine moving unit 31 of the stripping device 10 is mounted in a state along the X-axis direction. In addition, at both ends of the support plate 65 in the X-axis direction, a base end side nozzle 70 and a wire nozzle 71 are provided in a manner of sandwiching the stripping device 10 and at a predetermined interval from the stripping device 10.

[0067] The base end side nozzle 70 guides the conductive wire 8 to which a certain tension is applied by the tension device 53 to the stripping device 10, and is provided coaxially with the rotating member 22 as the second rotating member whose base end faces the stripping machine 21. On the other hand, the wire material nozzle 71 is provided coaxially with the rotating member 12 whose top end faces the stripping machine 11, through which the conductive wire 8 passing through the stripping device 10 is inserted.

[0068] In addition, the winding device 50 includes a winding unit 64 that winds the conductive wire 8 that has passed through the stripping device 10 around the wound member 40. Figure 5 as well as Figure 6 As shown, the winding unit 64 includes a wire nozzle 71 through which the conductive wire 8 passing through the peeling device 10 is inserted, and a nozzle moving unit 66 that moves the support plate 65 provided with the wire nozzle 71 in three-axis directions.

[0069] As the wire-wound component 40, a wire-wound component having a winding body 41, a pair of flanges 42, and a pair of pins 42a, 42b is used, wherein the winding body 41 is for winding the conductive wire 8; the pair of flanges 42 are provided on both sides of the winding body 41 and limit the winding width of the conductive wire 8 in the winding body 41; the pair of pins 42a, 42b are provided on one side of the flange 42 and are used to form a winding start connection portion and a winding end connection portion. The winding unit 64 that winds the conductive wire 8 on the wire-wound component 40 of the above-mentioned shape rotates the wire-wound component 40, thereby winding the conductive wire 8 unwound from the nozzle 71 on the winding body 41 of the wire-wound component 40. In addition, the shape of the wire-wound component 40 described above is an example, and the shape of the wire-wound component 40 is not limited thereto.

[0070] The winding unit 64 has a rotating body 43 that rotates the wound member 40. The rotating body 43 has a shape that can be inserted into the inner side of the winding body 41 of the wound member 40, and the wound member 40 can be freely attached and detached relative to the rotating body 43. The rotating body 43 is supported by the support column 44 erected on the stand 50a so that the ends on both sides of the rotation axis direction protrude from the support column 44 so as to be freely rotatable.

[0071] like Figure 5 as well as Figure 7 As shown, a pulley 46 is engaged with the end opposite to the end on which the wire-wound member 40 is mounted, through the support 44, of the two ends of the rotating body 43. In addition, a motor 47 serving as a rotating unit for rotating the rotating body 43 is provided on the support 44. The motor 47 is provided on the support 44 in such a manner that the rotating shaft 47a is parallel to the rotation center of the rotating body 43, and a pulley 48 is provided on the rotating shaft 47a of the motor 47. In addition, the motor may be provided on the stand 50a instead of the support 44.

[0072] A belt 45 is hung between a pulley 46 of the rotating body 43 and a pulley 48 of a rotating shaft 47a of a motor 47. Thus, when the motor 47 is driven, the rotating body 43 is driven to rotate via the belt 45. By fitting the wire-wound member 40 into the rotating body 43, the wire-wound member 40 and the rotating body 43 rotate together.

[0073] Since the wire-wound member 40 and the rotating body 43 are rotated together by the motor 47 , the conductive wire 8 unwound from the wire nozzle 71 is wound around the winding body 41 of the wire-wound member 40 .

[0074] In addition, the winding device 50 includes: a locking portion 75 that locks the conductive wire 8 that has passed through the wire nozzle 71; and a locking portion moving unit 76 that moves the locking portion 75. The locking portion 75 includes: a wire holding device 75c that can hold the conductive wire 8 through a pair of clamping pieces 75a and 75b opened and closed by fluid pressure; and a motor 75d that rotates the wire holding device 75c. The locking portion moving unit 76 has a structure that can move the locking portion 75 in three axial directions.

[0075] The locking portion moving unit 76 has the same structure as the nozzle moving unit 66, and the locking portion 75 is mounted on the housing 78d of the Y-axis telescopic actuator 78 so that the locking portion 75 can move in the Y-axis direction. In addition, in order to enable the locking portion 75 to move in the Z-axis direction together with the Y-axis telescopic actuator 78, the follower 78c of the Y-axis telescopic actuator 78 is mounted on the follower 79c of the Z-axis telescopic actuator 79. In addition, in order to enable the support plate 75 to move in the X-axis direction together with the Y-axis and Z-axis telescopic actuators 78 and 79, the housing 79d of the Z-axis telescopic actuator 79 is mounted on the follower 77c of the X-axis telescopic actuator 77. The housing 77d of the X-axis telescopic actuator 77 is fixed to the stand 50a in a state along the X-axis direction.

[0076] Each servomotor 77a to 79a of each telescopic actuator 77 to 79 is connected to a controller (not shown) that controls them. When the servomotor 77a to 79a is driven according to a command from the controller to rotate the ball screws 77b to 79b, the follower 77c to 79c screwed with the ball screws 77b to 79b moves along the long side direction of the housing 77d to 79d. Through the operation of the telescopic actuators 77 to 79, the locking portion 75 can move in three axial directions.

[0077] After the conductive wire 8 extending from the tip of the wire nozzle 71 passes between the pair of clamping pieces 75a and 75b, the pair of clamping pieces 75a and 75b are closed, so that the conductive wire 8 is held by the locking portion 75. The locking portion 75 holding the conductive wire 8 is moved in the three-axis direction by the locking portion moving unit 76.

[0078] Next, a method of winding the conductive wire will be described.

[0079] The winding method of the conductive wire 8 comprises: a winding initial stripping step, in which the insulating film of the conductive wire 8 whose top end is locked in the locking portion 75 is stripped by a predetermined length by moving the knife 14 pushed around the conductive wire 8 toward the top end side of the conductive wire 8, thereby forming a winding initial stripping portion 8a; a winding initial locking step, in which the winding initial stripping portion 8a is locked in the winding initial connecting portion 42a of the wound component 40; a winding initial cutting step, in which the conductive wire 8 between the winding initial connecting portion 42a and the locking portion 75 is cut near the winding initial connecting portion 42a; a winding step, in which the conductive wire 8 continuous with the winding initial stripping portion 8a is wound around the wound component 40. Wire component 40; a winding end stripping process, which is to move the knife 24 pushed around the conductive wire 8 toward the base end side of the conductive wire 8, thereby stripping the insulating film of the winding end portion of the conductive wire 8 by a predetermined length, thereby forming a winding end stripping portion 8b; a winding end locking process, which makes the winding end stripping portion 8b be locked to the winding end connection portion 42b of the wound component 40; a temporary fixing process, which makes the conductive wire 8 extending from the winding end connection portion 42b to the base end side be locked to the locking portion 75; a winding end cutting process, which cuts the conductive wire 8 between the winding end connection portion 42b and the locking portion 75 near the winding end connection portion 42b.

[0080] When the winding device 50 having the above-described structure is used, a preparation step is first performed before the winding initial peeling step. In the preparation step, the wound member 40 is fitted into the rotating body 43 of the winding device 50 , and the conductive wire 8 is mounted on the winding device 50 .

[0081] In order to install the conductive wire 8, the conductive wire 8 wound and stored on the bobbin 52 is prepared. Figure 6 As shown, the bobbin 52 is mounted on the side of the housing 54 of the tension device 53 and is set to a state where it can be rotated by the unwinding control motor 57. In addition, the conductive wire 8 unwound from the bobbin 52 is guided to the guide pulley 58 provided at the top end of the tension rod 56, and then passes through the base end side nozzle 70 and is guided to the peeling device 10.

[0082] The conductive wire 8 guided to the stripping device 10 is inserted through the rotating members 12 and 22 of both the distal end-directed stripping device 11 and the proximal end-guided stripping device 21 . The conductive wire 8 having passed through the rotating members 12 and 22 is further inserted into the wire nozzle 71 .

[0083] In addition, if Figure 5 As shown, the locking portion 75 provided on the stand 50a clamps the tip of the conductive wire 8 unwound from the wire nozzle 71, so that the conductive wire 8 is set to a state where it does not move, that is, the conductive wire 8 is not pulled back even if it is stretched by the tension device 53. From the above state, the winding initial peeling step is performed.

[0084] In the initial stripping process of winding, the knife 14 pushed around the conductive wire 8 is moved toward the top end side of the conductive wire 8, so that the top end of the stripping device 10 is used to strip the insulating film of the conductive wire 8 whose top end is fixed to the fixing portion 75 toward the stripping machine 11 to a predetermined length, thereby forming the initial stripping portion 8a of winding.

[0085] Specifically, when the insulation film is required to be stripped, the controller drives the motor 17 with the top end facing the stripping machine 11, such as Fig. 8A As shown by the solid arrow, the rotating member 12 is rotated at a rotation speed corresponding to the wire diameter of the conductive wire 8. As the rotating member 12 rotates, the blade 14, the blade shaft 13 and the hammer 15 mounted on the rotating member 12 via the flanges 12a and 12b revolve around the conductive wire 8.

[0086] Each hammer 15 is rotated radially outward around the axis of each blade shaft 13 by the centrifugal force corresponding to the rotation speed of the rotating member 12 in a manner that overcomes the force of the leaf spring 18 (see Figure 3 ). As a result, the blade shaft 13 rotates, and the blade portion 14a of each blade 4 comes into contact with the conductive wire 8 and is pressed against the conductive wire 8.

[0087] In this way, when the blade 14a is pressed against the conductive wire 8 and revolves around the conductive wire 8, Figure 8B As shown in FIG. 1 , the tip-toward stripping machine 11 is moved by a necessary length toward the tip side of the conductive wire 8. This movement is performed by the stripping machine moving unit 31. Since the tip-toward stripping machine 11 moves in a state where the blade 14a of the knife 14 is in contact with the side surface of the conductive wire 8 inserted through the rotating member 12, the insulating film of the conductive wire 8 is stripped by the blade 14a of the knife 14 in contact with the conductive wire 8.

[0088] When the predetermined length of the insulating film is stripped, the movement of the top end toward the stripper 11 by the stripper moving unit 31 stops, and the rotation of the rotating member 12 by the motor 17 also stops. Figure 2 As shown, the hammer 15 is returned to its initial position by the biasing force of the leaf spring 18, and the blade 14a of the knife 14 is also returned to its initial position separated from the conductive wire 8. Thus, the stripping of the insulating film from the tip toward the stripping machine 11 stops.

[0089] Here, if Figure 8B As shown in FIG. 1 , the stripped insulating film is in close contact with the blade 14 and moves toward the tip of the guide wire 8 together with the blade 14. Figure 8CAs shown in FIG. 1 , at the portion where the blade 14a of the blade 14 is separated from the conductive wire 8, i.e., the stripping end portion, a portion of the stripped insulating film moving together with the blade 14 remains on the surface of the conductive wire 8, and becomes a winding initial stripping residue 8c. Since the top-end stripping machine 11 strips the insulating film by the blade 14 while moving toward the top end side of the conductive wire 8, the winding initial stripping residue 8c generated by the stripping performed by the top-end stripping machine 11 is formed on the top end side of the winding initial stripping portion 8a.

[0090] Next, the winding initial locking process is implemented. In the winding initial locking process, if Fig. 9B As shown in FIG. 1 , the winding initial stripping portion 8a formed by stripping the insulating film is locked to the winding initial connection portion 42a of the wound member 40. As described above, since the wound member 40 has a pair of pins 42a and 42b constituting the winding initial connection portion and the winding end connection portion, the winding device 50 uses the nozzle moving unit 66 to move the wire nozzle 71 together with the support plate 65, and rotates the wire nozzle 71 around the pin 42a constituting the winding initial connection portion (see FIG. 1 ). Fig. 9B ). Thus, the winding initial peeling portion 8a unwound from the wire nozzle 71 is wound around the pin 42a.

[0091] Here, at the time point when the winding initial peeling process is completed, the winding initial peeling portion 8a has not yet been unwound from the wire nozzle 71. Fig.9A As shown, the locking portion 75 that locks the top of the conductive wire 8 is moved away from the wire nozzle 71 by the locking portion moving unit 76, and the winding initial peeling portion 8a is unwound from the wire nozzle 71, and then the winding initial peeling portion 8a is wound around the pin 42a. Fig.9A as well as Fig. 9B The reference numeral 8d shown in the figure indicates the winding completion peeling residue 8d generated when the winding is previously performed.

[0092] like Fig. 9B As shown in the figure, the wire nozzle 71 is rotated with the pin 42a on one side as the center, so that the winding initial peeling portion 8a is wound around the pin 42a. However, the winding initial peeling residue 8c generated in the winding initial peeling process is formed on the top side of the winding initial peeling portion 8a. That is, the winding initial locking process is completed in a state where the winding initial peeling residue 8c generated in the winding initial peeling process is located between the locking portion 75 and the winding initial connecting portion, that is, the pin 42a on one side.

[0093] Next, the winding initial cutting process is carried out. Fig. 9CAs shown, in the winding initial cutting step, the conductive wire 8 extending from the pin around which the winding initial peeling portion 8a is wound and locked, that is, the winding initial connecting portion 42a to the locking portion 75 is cut near the winding initial connecting portion 42a.

[0094] Specifically, the locking portion moving means 76 for moving the locking portion 75 is used to move the locking portion 75 locking the distal end of the conductive wire 8 away from the winding initial connection portion 42a, thereby breaking the conductive wire 8 near the winding initial connection portion 42a and cutting it.

[0095] Since the conductive wire 8 is cut near the initial winding connection portion 42a during the initial winding cutting process, the initial winding stripping residue 8c remains on the side of the conductive wire 8 fixed on the fixing portion 75, thereby avoiding the situation in which the initial winding stripping residue 8c remains on the initial winding stripping portion 8a of the conductive wire 8 wound on the connection portion 42a of the wound component 40.

[0096] In addition, the conductive wire 8 with the winding initial peeling residue 8 c remaining thereon is then removed from the locking portion 75 and discarded.

[0097] When the winding initial cutting process is completed, the winding process is then carried out. Fig.11A As shown, in the winding process, the conductive wire 8 is continuously wound on the wire material nozzle 71 side from the winding initial stripping portion 8a. Specifically, in the winding process, the rotating body 43 is rotated together with the wound member 40 by the rotating unit, that is, the motor 47, for a necessary number of turns.

[0098] In addition, at this time, the following can also be implemented, that is, through the nozzle moving unit 66, the wire nozzle 71 is moved back and forth between a pair of flanges 42 of the wound component 40, that is, reciprocated along the Y-axis direction, so that the conductive wire 8 unwound in sequence from the wire nozzle 71 is arranged and wound on the winding main body 41.

[0099] When the winding process is completed, the winding end peeling process is then carried out. FIG. 10A to FIG. 10C As shown, in the winding end stripping process, the knife 24 pushed around the conductive wire 8 is moved toward the base end side of the conductive wire 8 opposite to the top end side, so that the insulating film at the winding end position of the conductive wire 8 is stripped of a predetermined length by the base end of the stripping device 10 toward the stripping machine 21, thereby forming the winding end stripping portion 8b.

[0100] In a state where the conductive wire 8 unwound sequentially from the wire nozzle 71 is wound around the wound member 40 by a predetermined amount through the winding process, when stripping of the insulating film at a portion corresponding to the winding end portion is required, the controller drives the motor 27 with the base end toward the stripping machine 21, as shown in FIG. Fig. 10A As shown by the solid arrow in the middle, the rotating member 22 is rotated at a rotation speed corresponding to the wire diameter of the conductive wire 8. The blade 24, the blade shaft 23, and the hammer 25 as the second hammer revolve around the conductive wire 8 along with the rotation of the rotating member 22. Each hammer 25 is rotated radially outward with each blade shaft 23 as an axis by the centrifugal force corresponding to the rotation speed of the rotating member 22. As a result, each blade shaft 23 rotates, as shown in FIG. Fig. 10A As shown, the blade portion 24 a of each blade 24 is pressed so as to come into contact with the conductive wire 8 .

[0101] In this way, when the blade 24a is pressed against the conductive wire 8 and revolves around the conductive wire 8, Fig. 10B As shown in FIG. 2 , the base end stripping machine 21 is moved by a necessary length toward the base end side of the conductive wire 8. This movement is performed by the stripping machine moving unit 31. Since the base end stripping machine 21 moves in a state where the blade 24a of the knife 24 is in contact with the side surface of the conductive wire 8 inserted into the rotating member 22, the insulating film of the conductive wire 8 is stripped by the blade 24a of the knife 24 in contact with the conductive wire 8.

[0102] In addition, when the stripping of the predetermined length of the insulating film is completed, as shown in FIG. Fig. 10C As shown in FIG. 1 , the movement of the base end toward the stripping machine 21 by the stripping machine moving unit 31 stops, and the rotation of the rotating member 22 by the motor 27 also stops. Since the rotation of the rotating member 22 stops, the position of the hammer 15 returns to the initial position due to the force of the leaf spring 28, and the position of the blade 24a of the knife 24 also returns to the initial position separated from the conductive wire 8. Thus, the stripping of the insulating film from the base end toward the stripping machine 21 stops.

[0103] Here, if Fig. 10B As shown in FIG. 1 , the stripped insulating film is in close contact with the blade 24 and moves toward the base end of the guide wire 10 together with the blade 24. Fig. 10C As shown in FIG. 1 , at the stripping end portion where the blade 24a of the knife 24 is separated from the conductive wire 8, a portion of the stripped insulating film moving together with the knife 24 remains on the surface of the conductive wire 8, and becomes a winding end stripping residue 8c. Since the base end stripping machine 21 strips the insulating film by the knife 24 while moving toward the base end side of the conductive wire 8, the winding end stripping residue 8d generated by the stripping performed by the base end stripping machine 21 is formed on the base end side of the winding end stripping portion 8b.

[0104] Thus, in the peeling device 10, as described in the winding initial peeling process, the peeling residue 8c can be formed on the tip side of the peeling portion 8a, and as described in the winding end peeling process, the peeling residue 8d can also be formed on the base side of the peeling portion 8b. Therefore, by using the peeling device 10 having the above structure, the direction in which the peeling residues 8c and 8d are generated can be arbitrarily changed to the tip side or the base side.

[0105] When the winding end peeling step is completed, the winding end locking step of locking the winding end peeling portion 8b formed by peeling the insulating film and the winding end connecting portion 42b of the wound member 40 is performed next.

[0106] Here, at the time point when the winding end stripping process is completed, the winding end stripping portion 8b has not yet been unwound from the wire nozzle 71. Fig.11A As shown, the wire-wound member 40 and the rotating body 43 are rotated together, so that the conductive wire 8 unwound from the wire nozzle 71 is wound around the wire-wound member 40 until the winding-end stripping portion 8b is unwound from the wire nozzle 71. Then, the winding-end stripping portion 8b is unwound from the wire nozzle 71 in such a manner that the winding-end stripping portion 8b can be wound around the pin 42b constituting the other side of the winding-end connecting portion.

[0107] In addition, if Fig. 11B As shown, the winding device 50 moves the wire nozzle 71 and the support plate 65 together through the nozzle moving unit 66, and rotates the wire nozzle 71 around the pin 42b constituting the other side of the winding end connection portion. Thereby, the winding end stripping portion 8b unwound from the wire nozzle 71 is wound around the pin 42b.

[0108] In this way, the winding end peeling portion 8b is wound around the other pin 42b. However, the winding end peeling residue 8d generated in the winding end peeling step is formed on the base end side of the winding end peeling portion 8b. That is, the winding end locking step is completed in a state where the winding end peeling residue 8d generated in the winding end peeling step is located closer to the base end side than the winding end connecting portion, that is, the other pin 42b.

[0109] Next, a temporary fixing process is performed. In the temporary fixing process, Fig. 11CAs shown, the conductive wire 8 extending from the winding end connection portion 42b to the base end side is locked by the locking portion 75 between the portion where the winding end stripping residue 8d remains and the wire nozzle 71. Therefore, it is necessary to sufficiently ensure a space for the locking portion 75 to enter between the winding end stripping residue 8d and the wire nozzle 71, so that the wire nozzle 71 is separated from the winding end stripping portion 8b before the temporary fixing process is implemented.

[0110] In the temporary fixing process, first, the locking portion 75 is moved by the locking portion moving unit 76 in such a manner that the conductive wire 8 extending from the tip of the wire nozzle 71 is located between the opened pair of clamping pieces 75a and 75b. Then, by closing the pair of clamping pieces 75a and 75b, as shown in FIG. Fig. 11C As shown in FIG. 1 , the conductive wire 8 is held by a pair of clamping pieces 75a and 75b. Fig. 11C , a state in which the conductive wire 8 is locked by the locking portion 75 between the winding completion peeling residue 8 d drawn out from the wire nozzle 71 and the wire nozzle 71 is shown.

[0111] In the winding end cutting step, the conductive wire 8 extending from the other pin 42b, that is, the winding end connection portion 42b, which is locked by the winding end peeling portion 8b, to the locking portion 75 is cut near the winding end connection portion 42b.

[0112] Specifically, if Fig.11D As shown, the locking portion moving unit 76 for moving the locking portion 75 is used to move the locking portion 75 that locks the conductive wire 8 away from the winding end connecting portion 42b, thereby tearing off the conductive wire 8 near the winding end connecting portion 42b and cutting it.

[0113] Since the conductive wire 8 is cut near the winding end connection portion 42b in the winding end cutting process, the winding end stripping residue 8d remains on the side of the conductive wire 8 clamped on the clamping portion 75, thereby avoiding the situation where the winding end stripping residue 8d remains on the winding end stripping portion 8b of the conductive wire 8 wound on the connection portion 42b of the wound component 40.

[0114] Since the winding and cutting process is completed, a series of winding operations for the wound member 40 are completed, and the wound member 40 with the wound wire is removed from the rotating body 43. In addition, since another wound member 40 is re-engaged in the rotating body 43, the next winding operation is started.

[0115] In this way, according to the winding method using the winding device 50 of the above structure, it is possible to avoid the situation where stripping residues 8c and 8d remain on the stripping portions 8a and 8b of the conductive wire 8 connected to the connecting portions 42a and 42b of the wound component 40, thereby improving the electrical connectivity of the stripping portions 8a and 8b of the conductive wire 8.

[0116] In addition, in the above-mentioned embodiment, the locking portion moving unit 76 and the nozzle moving unit 66 are formed by combining the telescopic actuators in the X-axis, Y-axis, and Z-axis directions. The structure of the locking portion moving unit 76 and the nozzle moving unit 66 is not limited to this, and any structure can be used as long as the locking portion 75 and the wire nozzle 71 can be moved in the three-axis direction relative to the frame 50a.

[0117] In the above-mentioned embodiment, the tension device 53 tilts the tension rod 56 by the force of the spring 61, thereby applying tension to the conductive wire 8. The unit for applying tension to the conductive wire 8 is not limited thereto, and for example, a unit for applying tension to the conductive wire 8 by controlling the rotation of the bobbin 52 by controlling the motor 57 and appropriately controlling the unwinding speed may also be used.

[0118] In the above-mentioned embodiment, the top-end facing stripper 11 and the base-end facing stripper 21 are disposed adjacently on the square platen 30 so as to face the blades 14, 24 provided at the top ends of the blade shafts 13, 23. Alternatively, the top-end facing stripper 11 and the base-end facing stripper 21 may be disposed so as to face the hammers 15, 25 provided at the rear ends of the blade shafts 13, 23.

[0119] In the above-mentioned embodiment, the stripper moving unit 31 moves along the long side direction of the conductive wire 8 with both the tip end toward the stripper 11 and the base end toward the stripper 21. Alternatively, the stripper moving unit 31 may be provided with respect to each stripper 11, 12 so as to move the tip end toward the stripper 11 and the base end toward the stripper 21. In this case, the strippers 11, 12 that only perform the stripping of the insulating film are moved by the stripper moving unit 31. In addition, for example, since the stripping device 10 is moved along the X-axis direction by the X-axis direction telescopic actuator 67 of the nozzle moving unit 66, if the insulating film of the conductive wire 8 can be stripped, a structure in which the nozzle moving unit 66 also serves as the stripper moving unit 31 may be adopted.

[0120] In the above embodiment, the winding start connection portion and the winding end connection portion are constituted by a pair of pins 42a and 42b provided on the flange 42 of one side of the wound member 40. As an alternative, the connection portion may be a connection portion in which the winding start peeling portion 8a and the winding end peeling portion 8b are drawn out as guide wires from the conductive wire 8 wound on the winding main body 41 of the wound member 40 in a manner not wound on the pins. In this case, the conductive wire 8 is not cut by tearing, but is cut by using a knife or the like.

[0121] In addition, in the above-mentioned embodiment, the locking portion 75 is composed of a wire holding device 75c, etc., and the wire holding device 75c can hold the conductive wire 8 through a pair of clamping pieces 75a and 75b opened and closed by fluid pressure. The locking portion 75 is not limited to the above-mentioned structure, and any structure can be used as long as it can hold the conductive wire 8. For example, it can also be a rod-shaped component that is wound around the conductive wire 8 to hold the conductive wire 8.

[0122] In addition, in the above-mentioned embodiment, the locking portion moving unit 76 that moves the locking portion 75 is used as a cutting device for cutting the conductive wire 8. The cutting device for cutting the conductive wire 8 is not limited thereto, and any structure can be used as long as it can cut the conductive wire 8. For example, a knife that can directly cut the conductive wire 8 can also be used as the cutting device.
