Description

  The present invention relates to a wire tying device for tying an end of a wire to an elongated terminal, a winding device using the same, and a wire tying method.

  2. Description of the Related Art Conventionally, in a winding device that winds a wire around a member to be wound, the end of the wire is often entangled with an elongated pin-like terminal provided on the member to be wound before and after the winding.

  In the wire tying device for tying the end of this wire to an elongated terminal, it has a cylindrical member into which an elongated pin-like terminal can be inserted, and a rotating means for rotating the cylindrical member around the terminal. As a method of tying the end of the wire rod to the terminal using it, the end of the wire rod is aligned with the terminal, the terminal is inserted into the tubular member, and the tubular shape is centered on the terminal. By rotating the member, the wire is entangled with the terminal (for example, see Patent Document 1).

  And since the conventional elongate pin-shaped terminal provided in this to-be-wound member needs to be provided to the to-be-wound member by driving or the like, a relatively high-rigidity terminal is used, and the terminal is not easily deformed. For this reason, it is said that there is no problem in inserting such an elongated pin-shaped terminal into the cylindrical member.

Japanese Patent Laid-Open No. 5-315179 (paragraph “0016”, FIG. 8)

  However, the processing of the end portion of the wire is not limited to the case where it is entangled with a pin-like terminal having relatively high rigidity, and the wire wound around the member to be wound is often connected to the insulated wire. This insulated wire has a conductor covered with an insulator and is known to be deformable. And the connection of the wire end part to this insulated wire is performed by peeling the insulator at the insulated wire end part to expose the conductor, and tying and soldering the wire to the conductor.

  Here, the conductor of the insulated wire is exemplified by a twist of a plurality of thin copper wires, and this conductor is known to be relatively soft and easily deformable in order to ensure the deformability of the insulated wire.

  When such a conductor is used as a terminal and the wire rod is entangled using the above-described conventional wire rod binding device, the conductor is easily deformed, so that the conductor is not straight and is deformed. If it becomes difficult to insert the terminal made of the conductor into the cylindrical member, and the conductor serving as the terminal cannot be inserted into the cylindrical member, the wire is entangled with the conductor even if the cylindrical member is rotated. There was a bug that could not be done.

  For this reason, when the terminal is relatively soft and easily deformable, a wire rod feeding member such as a nozzle for feeding the wire rod is circulated around the terminal without using a cylindrical member, and the wire is fed therefrom. It is also possible to tie the wire directly to the terminal.

  However, when the terminal is easily deformable, if the wire is circulated around the terminal without supporting the terminal at all, the terminal is pulled by the wire that circulates around and the terminal itself is deformed, and the wire is entangled. It also causes a problem that it cannot be performed.

  An object of the present invention is to provide a wire tying device capable of reliably tying a wire to the terminal, even a relatively soft terminal, a winding device using the same, and a wire tying method.

  The present invention is an improvement of a wire binding apparatus that includes a rotating body and a rotating unit that rotates the rotating body, and the end of the wire is bound to an elongated terminal by the rotating body.

  The characteristic configuration is that the rotating body has a protrusion formed with a plane including a rotation axis of the rotating body or a parallel axis parallel to the rotation axis, and a terminal groove capable of accommodating a terminal is formed on the plane. A wire rod groove is formed at the tip of the projecting portion and extending in the rotational radial direction so as to communicate with the terminal groove, and the rotating means rotates the rotating body around the terminal accommodated in the terminal groove. By the way.

  In this wire binding device, a pair of wire rod grooves are preferably formed at the tip of the protruding portion so as to sandwich the terminal groove, and a deep lateral groove is formed in a direction away from each other at the bottom of each of the pair of wire rod grooves. You can also It is further preferable that the tip of the protrusion is rounded.

  Another invention provides a support member capable of supporting a member to be wound, winding means for winding a wire around the member to be wound supported by the support member, terminal support means for supporting an elongated terminal, It is a winding apparatus provided with the said wire rod binding apparatus which winds the edge part of the wire wound around the winding member around a terminal.

  Yet another aspect of the present invention is a method of binding a wire, in which the wire is bound to an elongated terminal using the above-described wire binding device.

  The characteristic point is that the end of the wire is accommodated in the wire groove formed at the tip of the protrusion, the terminal is accommodated in the terminal groove formed in the protrusion, and the rotating body is rotated around the terminal. The end of the wire housed in the wire groove is made to circulate around the terminal.

  In the wire tying device of the present invention, the winding device using the same, and the wire tying method, when the wire is tied to the terminal, the rotating body is rotated around the terminal accommodated in the terminal groove, and the wire is taken. Since the end of the wire rod accommodated in the groove for the circuit is circulated around the terminal, the end portion of the wire rod accommodated in the groove for the wire rod is sequentially pulled out from the groove for the wire rod to the terminal side and is entangled with the terminal. Become.

  Here, since the terminal is housed in the terminal groove and the wire circulates around the periphery together with the rotating body, the terminal is supported by the terminal groove even if the terminal is pulled by the wire drawn from the wire groove. Thus, the wire is not bent in the direction of the wire groove from which the wire is drawn.

  Even if the terminals are curved in advance and not all of them are accommodated in the terminal grooves, if the wire wraps around the periphery together with the rotating body, the terminals are sequentially placed on the wire drawn from the wire grooves. The terminal is accommodated in the terminal groove by being pulled, and the wire can be entangled with the terminal accommodated and supported in the terminal groove.

  Therefore, in the present invention, even if the elongated terminal is relatively soft, the wire can be reliably entangled with the terminal.

  Next, a winding procedure using such a winding apparatus will be described.

  In winding, first, the member to be wound 11 is supported by the support member 13 as shown in FIG. This is performed by fitting the winding body 11 c of the member to be wound 11 into the support member 13.

  Further, the terminal is supported by the terminal support means 52. Since the terminal in this embodiment is the conductor 51a at the end of the insulated wire 51, the insulated wire 51 is prepared by removing the insulator 51b at the end to expose the conductor 51a, and the insulator 51b is removed. Then, the exposed conductor 51a is inserted downward into the tube 53, and the insulated wire 51 protruding from the lower end of the tube 53 is gripped by the wire clamp device. Here, the protruding amount of the insulated wire 51 from the lower end of the tube 53 is made constant.

  In supporting the wound member 11 and supporting the insulated wire 51 by the wire clamp device 54, the vertical plate 14 provided with the support member 13 and the tube 53 is separated from the flyer 22 by the one-dot chain line in FIG. Then, the ball screw 16 is rotated by the motor 17, and the vertical plate 14 is moved to the winding position where the support member 13 faces the flyer 22.

  On the other hand, in actual winding, as shown in FIG. 5, the wire 19 is passed from a wire supply source (not shown) to the guide tube 22c in the flyer 22, and the wire 19 fed from the tip of the guide tube 22c is passed through the passage hole 22f. After passing, it is turned at the small pulley 22 d and passed through the nozzle 21. As shown in FIG. 1, the end portion of the wire 19 drawn out from the nozzle 21 is held by the first clamping device 31.

  Next, in this winding, as shown in FIG. 5, the nozzle 21 is rotated around the member to be wound 11, and the wire 19 fed out from the nozzle 21 is turned on the member to be wound 11. It winds around the winding drum part 11c (FIG. 1).

  Specifically, the first clamp device 31 that grips the end of the wire 19 is moved by the mounting plate moving mechanism 33, and the wire 19 extending from the nozzle 21 to the first clamp device 31 is wound at the winding position. 11 is pulled into the winding body 11c (FIG. 1). Then, the flyer 22 is moved by the nozzle moving means 31 to move the flyer 22 at the winding position whose rotational center coincides with the central axis of the member to be wound 11, and the nozzle provided at the tip of the flyer 22. 21 is made to oppose the circumference | surroundings of the winding trunk | drum 11c of the member 11 to be wound.

  Then, as shown in FIG. 5, the flyer 22 is rotated together with the nozzle 21 by the winding motor 23. As a result, the wire 19 fed from the nozzle 21 is wound around the winding body 11 c of the member to be wound 11.

  At this time, it is preferable that the nozzle 21 rotating around the winding drum portion 11c is reciprocated within the range of the width of the winding drum portion 11c as shown by the broken line arrow in FIG. That is, it is preferable to move the nozzle 21 together with the flyer 22 in the axial direction of the wound member 11 by an amount equal to the wire diameter of the wire rod 19 every time the flyer 22 rotates together with the nozzle 21.

  Then, when the wire 19 has been wound a predetermined number of times, the rotation of the flyer 22 is stopped to finish the winding.

  Next, the wire 19 is wound around the winding body 11c and drawn out, and the wire 19a at the beginning of winding and the wire 19b at the end of winding shown in FIG. 5 are bound to the terminal 51a. This binding is performed by the wire binding device 61.

  First, the binding of the wire rod 19a at the beginning of winding will be described. First, the wire clamp moving mechanism 45 moves the second clamp device 41 to extend the wire rod 19a at the beginning of winding extending from the member to be wound 11 to the first gripping means 31. Is held by the second clamping device 41. Thereafter, the gripping of the wire 19 by the first clamping device 31 is canceled, the first mounting plate 32 provided with the first clamping device 31 is moved by the mounting plate moving mechanism 33, and the first mounting plate 32 is provided. The wire binding device 61 is moved. Then, as shown in FIG. 8, the wire 19a at the beginning of winding is caused to enter the wire rod groove 62e of the rotating body 62 in the wire rod binding device 61.

  Here, since the wire groove 62e is formed in a pair so as to sandwich the terminal groove 62d at the tip of the projecting portion 62b, the rotating body 62 is rotated thereafter, but the wire material on the rear side in the rotation direction. The wire 19a at the beginning of winding is caused to enter the groove 62e (FIG. 7).

  Next, the first attachment plate 32 is further moved by the attachment plate moving mechanism 33, and the wire binding device 61 is maintained as shown in FIG. The conductor 51a of the insulated wire 51 to be a terminal enters the terminal groove 62d of the rotating body 62 in FIG.

  Thereafter, the gripping of the wire rod 19 a at the beginning of winding by the second clamp device 41 is canceled, or the wire rod 19 a at the beginning of winding is cut in the vicinity of the second clamp device 41 by the nipper device 43. In the drawing, the wire 19a is cut by the nipper device 43. In this way, the wire rod 19a at the beginning of the length L that can be wound around the terminal 51a is left in the vicinity of the terminal 51a.

  Then, the rotating body 62 is rotated around the terminal 51a by the binding servo motor 63 (FIG. 2).

  Then, as shown in FIG. 7, the wire 19a at the beginning of winding turns around the terminal 51a together with the rotating body 62 while entering the wire groove 62e. Then, the wire 19 accommodated in the wire groove 62e enters the lateral groove 62f. For this reason, when the rotating body 62 is rotated, the wire 19 is prevented from being detached from the wire groove 62e.

  On the other hand, the conductor 51a of the insulated wire 51 that enters the terminal groove 62d and becomes the terminal accommodated therein does not rotate. For this reason, when the rotating body 62 is rotated, the winding wire 19a housed in the wire groove 62e is sequentially drawn from the wire groove 62e toward the conductor 51a and wound around the conductor 51a serving as the terminal. Will be turned.

  Here, the terminal 51a is kept in a state of being accommodated in the terminal groove 62d in the rotating body 62, and the wire 19 circulates around the periphery together with the rotating body 62. Therefore, the terminal 51a is sequentially pulled out from the wire rod groove 62e. Is pulled, the terminal 51a is supported by the terminal groove 62d. For this reason, even if the terminal 51a is a relatively soft conductor in the insulated electric wire 51, the soft terminal 51a is not bent in the direction of the wire rod groove 62e from which the wire rod 19 is sequentially drawn.

  Even if the terminal 51a is curved in advance and not all of the terminal 51a is accommodated in the terminal groove 62d, when the wire 19 circulates around the periphery together with the rotating body 62, the terminal 51a is pulled out from the wire groove 62e. Since the terminals 51a are sequentially pulled on the wire 19 and the terminals 51a are accommodated in the terminal grooves 62d as shown in FIG. 10, the wires 51 are accommodated in the terminals 51a accommodated and supported in the terminal grooves 62d. 19 can be reliably bound.

  At this time, as shown in FIG. 10, every time the wire 19a at the beginning of winding is wound around the terminal 51a once, the rotating body 62 is lowered to the outer diameter of the wire 19 or more, and It is preferable that the wire 19a is spirally wound around the terminal 51a along the axial direction. Then, when all of the winding wire 19a left in the vicinity of the terminal 51a is wound around the terminal 51a, the winding of the winding wire 19a to the terminal 51a is terminated.

  Next, the wire 19b at the end of winding extending from the member to be wound 11 to the nozzle 21 is bound to another terminal 51a. The winding wire 19b is tied to another terminal 51a in the same procedure as the winding wire 19a to the terminal 51a.

  That is, the cutter clamp moving mechanism 45 moves the second clamp device 41, which has released the grip of the wire 19a at the beginning of winding, together with the nipper device 43, so that the wire 19b at the end of winding extending from the member to be wound 11 to the nozzle 21 is moved. New gripping is performed by the second clamping device 41.

  Then, similarly to the wire rod 19 a at the beginning of winding, the first mounting plate 32 is moved by the mounting plate moving mechanism 33, and the wire rod groove 62 e of the rotating body 62 in the wire binding device 61 provided on the first mounting plate 32. The wire rod 19b at the end of winding is made to enter.

  Here, since the wire groove 62e is formed in a pair so as to sandwich the terminal groove 62d at the tip of the projecting portion 62b, the rotating body 62 is rotated thereafter, but the wire material on the rear side in the rotation direction. The wire rod 19b at the end of winding is made to enter the groove 62e.

  Next, the first mounting plate 32 is further moved by the mounting plate moving mechanism 33, and the terminal end of the rotating body 62 in the wire rod binding device 61 is maintained while maintaining the state where the wire rod 19b at the end of winding has entered the wire rod groove 62e. A conductor 51a of another insulated wire 51 that becomes a terminal is inserted into the groove 62d.

  After that, in the state where the winding end wire 19b is gripped by the second clamping device 41, the winding end wire 19b extending from the second clamping device 41 to the wound member 11 is disposed in the vicinity of the second clamping device 41. Cut by the nipper device 43. In this way, the winding end wire rod 19b having a length that can be wound around the terminal 51a is left in the vicinity of the terminal 51a. Then, the rotator 62 is rotated again around the terminal 51 a by the binding servo motor 63.

  Then, as shown in FIG. 11, the winding end wire rod 19b that has entered the wire rod groove 62e is circulated around the terminal 51a together with the rotating body 62, and is sequentially drawn out from the wire rod groove 62e and wound around the terminal 51a. .

  At this time, every time the winding end wire rod 19b is wound around the terminal 51a once, the rotating body 62 is lowered beyond the outer diameter of the wire rod 19, and the winding end wire rod 19b is moved around the terminal 51a. It is preferable that the wire is spirally wound along the axial direction. Then, when all of the winding end wire 19b left in the vicinity of the terminal 51a is wound around the terminal 51a, the binding of the winding end wire 19b to another terminal 51a is terminated.

  Thus, after the winding wire 19a and the winding wire 19b are entangled with the terminal 51a, the wire 19 extending from the second clamping device 41 to the nozzle 21 is gripped by the first clamping device 31, After canceling the grip of the wire 19 by the second clamp device 41, both the first and second clamp devices 31, 41 are returned to the standby position shown in FIG. Prepare for winding.

  Then, the winding wire 19a and the winding wire 19b wound around the terminal 51a are then electrically connected to the terminals 51a. This connection can be performed by a known general method that has been conventionally performed. For example, performing by soldering using a flux is exemplified.

  As described above, in the wire binding device 61 of the present invention, the winding device 10 using the wire binding device 61 and the method of binding the wire 19, the terminal groove 62 d in the rotating body 62 when the wire 19 is bound to the terminal 51 a. Since the end of the wire 19 accommodated in the wire groove 62e is rotated around the terminal 51a by rotating the rotating body 62 around the terminal 51a accommodated in the wire 51e, the end of the wire 19 accommodated in the wire groove 62e Can be sequentially drawn out from the wire groove 62e toward the terminal 51a and entangled with the terminal 51a.

  The terminal 51a is kept in a state where it is accommodated in the terminal groove 62d of the rotating body 62, and the wire rod 19 circulates around the periphery together with the rotating body 62. Even if it is pulled, the terminal 51a is supported by the terminal groove 62d. For this reason, even if the terminal 51a is a relatively soft conductor in the insulated electric wire 51, the soft terminal 51a is not bent in the direction of the wire rod groove 62e from which the wire rod 19 is sequentially drawn.

  Further, in the present invention, unlike the conventional one in which the terminal is inserted into the cylindrical member, the terminal 51a is curved because the terminal 51a merely accommodates the terminal 51a in the terminal groove 62d of the rotating body 62. However, the terminal can be along the terminal groove 62d.

  Even if the terminal 51a is curved in advance and not all of the terminal 51a is accommodated in the terminal groove 62d, when the wire 19 circulates around the periphery together with the rotating body 62, the terminal 51a is pulled out from the wire groove 62e. The terminals 51a are sequentially pulled by the wire 19 so that all of the terminals 51a are finally accommodated in the terminal grooves 62d, and the wire 19 is securely attached to the terminals 51a accommodated and supported in the terminal grooves 62d. It can be tied.

  Further, when the wire rod 19 is entangled, the wire rod 19 is inserted into the wire rod groove 62e on the rear side in the rotation direction for rotating the rotating body 62. The wire rod groove 62e is a terminal groove at the tip of the projecting portion 62b. Since the pair is formed so as to sandwich 62d, by selecting the wire groove 62e through which the wire 19 enters, the tangling direction of the wire 19 to the terminal 51a is entangled in either the forward or reverse direction. It becomes possible.

  Further, since the tip of the projecting portion 62b is rounded, when the wire 19 is advanced into the wire groove 62e, the wire 19 is slid on the tip of the rounded projecting portion 62b, thereby The wire 19 can be easily entered into the groove 62e. Further, the wire 19 that is wound around the terminal 51a and extends to the member to be wound 11 is guided by the roundness to the leading edge of the projecting portion 62b and passed through the leading edge, and the wire 19 is wound around the projecting portion 62b. It is possible to avoid such a situation.

  In addition, since the deep lateral grooves 62f are formed in the direction of separating from each other at the bottom of each of the pair of wire rod grooves 62e, when the rotating body 62 is rotated around the terminal 51a accommodated in the terminal groove 62d in the rotating body 62, The wire 19 accommodated in the wire groove 62e enters the lateral groove 62f. Then, it is possible to prevent the wire 19 from being detached from the wire rod groove 62e when the rotating body 62 is rotated and the wire 19 is entangled. For this reason, it becomes possible to pull out the wire 19 sequentially from the wire groove 62e to the terminal 51a side and to entangle the wire 19 to the terminal 51a.

  In the above-described embodiment, the case where the conductor 51a exposed by removing the insulator 51b at the end portion of the insulated wire 51 is used as a terminal is described. However, the terminal 51a is not limited to this, and is not limited thereto. It may be a relatively soft copper wire or a pin-shaped terminal having a relatively rigid cross section which is conventionally used in a circular or square shape.

  In the above-described embodiment, the nozzle moving means 30 that reciprocates the moving plate 26 in the Y-axis direction has been described. However, the nozzle moving means 30 is the same as the mounting plate moving mechanism 33 and the cutter clamp moving mechanism 45. In addition, the movable plate 26 may be movable in three axial directions.

  In the above-described embodiment, the case where the wire rod 19a at the beginning of winding is cut by the nipper device 43 to leave the wire wire 19a at the beginning of winding L having a length L that can be wound around the terminal 51a in the vicinity of the terminal 51a. However, the winding wire 19a having the length L that can be tangled to the terminal 51a may be left in the vicinity of the terminal 51a by eliminating the gripping of the winding wire 19a by the second clamping device 41.

  Furthermore, in the above-described embodiment, the case where the terminal 51a is caused to enter the terminal groove 62d after the winding wire 19a has entered the wire groove 62e has been described. However, if possible, the terminal 51a may be inserted into the terminal groove 62d before or at the same time as the winding wire 19a enters the wire groove 62e.
