<About conductive members>
First, the conductive member to be manufactured will be described. FIG. 1 is a schematic plan view showing the conductive member 10.

  The conductive member 10 is formed by combining a plurality of metal wires so as to form a long shape, and formed with joint portions 12 in which metal wires are joined to both ends. For example, the metal wire may be composed of only a metal wire, or may be a wire in which another metal plating layer is formed on the metal wire. The metal wire may be a copper wire, a copper alloy wire, an aluminum wire, or an aluminum alloy wire, and the metal plating layer may be tin plating. But the material of a metal strand and a metal plating layer is not limited to them. The conductive member 10 may be a member that is woven so that a plurality of metal wires form a cylinder (such as a tubular braid), and the plurality of metal wires may be strip-shaped from the beginning. It may be woven so as to form a sheet (such as a sheet-like metal cloth or a net).

  At both end portions of the conductive member 10, a joint portion 12 is formed by joining a plurality of metal wires. The joining of the plurality of metal wires may be performed by a hot press, may be performed by ultrasonic welding, or may be performed by other joining methods. Since the plurality of metal strands are joined at the joint portion 12, the plurality of metal strands are in a state of being electrically connected well, and the dispersion of the metal strands is suppressed. In the portion (intermediate region other than the end portion) of the conductive member 10 other than where the joint portion 12 is formed, the plurality of metal wires are not joined to each other and are easily bent.

  A terminal is connected to the end of the conductive member 10 by crimping or welding. The conductive member 10 is connected to other conductive parts (terminals of other electrical components, metal bodies) via the terminals. The joint portion 12 at the end of the conductive member 10 may be directly connected to a conductive portion to be connected by welding, screw fixing, or the like.

  In any case, the conductive member 10 is used as a wiring material for connecting various electrical components in a vehicle or the like.

  The conductive member 10 is manufactured as follows. That is, as shown in FIG. 2, a long metal wire member 10B in which a plurality of metal strands are combined with a long member having a length capable of manufacturing a plurality of conductive members 10 is prepared. The metal wire long member 10B is, for example, a member folded so that a member (such as a tubular braid) woven so that a plurality of metal strands form a cylinder becomes flat. The continuous joining part 12B is formed in this metal wire long member 10B at intervals. The continuous joint portion 12B has a length dimension corresponding to two joint portions 12. The continuous joining portion 12B is formed by, for example, a hot press mechanism portion 50 described later. And the longitudinal direction intermediate part of the continuous joining part 12B of the elongate member 10B made from a metal wire is cut | disconnected. The cutting may be performed by laser cutting, or may be performed by shearing or the like. FIG. 2 shows the state of being cut by the laser beam. Thereby, the said electrically-conductive member 10 in which the junction part 12 was formed in the both ends can be manufactured. Moreover, by repeating the above, it is possible to continuously and efficiently manufacture the conductive member 10 in which the joint portions 12 are formed at both ends.

<About the manufacturing apparatus of a conductive member, and the manufacturing method of a conductive member>
A conductive member manufacturing apparatus and a conductive manufacturing method will be described.

<About the overall configuration>
FIG. 3 is a schematic front view showing the overall configuration of the conductive member manufacturing apparatus 20.

  The conductive member manufacturing apparatus 20 includes a supply unit 30, a heating press mechanism unit 50 as a joining mechanism unit, a feed mechanism unit 60, and a laser cutting device 80 as a cutting mechanism unit. In the manufacturing apparatus 20, the long metal wire member 10 </ b> B continuously supplied from the supply unit 30 is intermittently sent along the feed line L by the feed mechanism unit 60. And in the state which the feed mechanism part 60 stopped the feed of the metal wire elongate member 10B, formation of the continuous joining part 12B by the heating press mechanism part 50 and cutting | disconnection of the continuous joining part 12B by the laser cutting device 80 are made | formed. By repeating the above, the conductive member 10 is continuously manufactured.

  More specifically, the manufacturing apparatus 20 for the conductive member 10 includes a first frame portion 22 and a second frame portion 24. The first frame portion 22 is configured to be assembled so that the rod-shaped frame forms a rectangular parallelepiped frame, and the second frame portion 24 is also configured to be assembled so that the rod-shaped frame forms a rectangular parallelepiped frame. The first frame portion 22 and the second frame portion 24 are adjacent to each other. A supply unit 30 is provided in the first frame unit 22, and a heating press mechanism unit 50, a feed mechanism unit 60, and a laser cutting device 80 are provided in the second frame unit 24. The first frame portion 22 and the second frame portion 24 are preferably covered with a protective plate. In particular, since the laser cutting device 80 is provided in the second frame portion 24, the second frame portion 24 is opaque and has laser energy in order to prevent leakage of laser light emitted by the laser cutting device 80 to the outside. Is covered with a protective plate capable of attenuating the light, or a protective plate capable of shielding the laser beam. Further, the space between the first frame portion 22 and the second frame portion 24 is also covered by the partition plate 26. In order to prevent the laser beam from the laser cutting device 80 from leaking to the first frame 22 side, the partition plate 26 is formed of an opaque plate capable of attenuating laser energy or a plate capable of shielding the laser beam. Has been.

  Further, in the first frame portion 22, a heat insulating plate member 23 is provided between the hot press mechanism portion 50 and the laser cutting device 80. As the heat insulating plate member 23, a resin foam plate member or the like can be used. An opening 23h is formed in a portion of the heat insulating plate member 23 where the feeding mechanism 60 is disposed. The heat insulating plate member 23 makes it difficult for heat generated by the heating press mechanism unit 50 to be transmitted to the laser cutting device 80 side, and heating of the optical system in the laser cutting device 80 is suppressed. In order to suppress heating of the optical system of the laser cutting device 80, it is preferable to discharge the air in the second frame portion 24 to the outside.

<About the supply unit>
The supply unit 30 is configured to be able to continuously supply the long metal wire member 10 </ b> B along the feed line L. More specifically, the supply unit 30 includes a reel 32 around which the metal wire long member 10B is wound and accommodated, and a reel support unit 34 that rotatably supports the reel 32.

  The reel 32 is, for example, a member in which a pair of disc-shaped flange portions 32b are fixed to both ends of the core 32a, and the long metal wire member 10B is attached to the core 32a between the pair of flange portions 32b. It is housed in a winding.

  The reel support portion 34 includes a pair of rollers 34a. The pair of rollers 34a is rotatably supported with a gap smaller than the diameter dimension of the flange portion 32b. Then, the pair of flange portions 32b is placed on the pair of rollers 34a in a state where the central axis of the reel 32 is along the horizontal direction orthogonal to the direction of gravity. In this state, when the metal wire long member 10B is pulled out from the reel 32, the pair of flange portions 32b rotate the pair of rollers 34a while the reel 32 rotates in the direction of feeding the metal wire long member 10B. In addition, the long metal wire member 10B can be continuously supplied.

  Note that at least one of the pair of rollers 34a may be rotationally driven by a motor or the like, so that the reel 32 is smoothly rotated in the direction in which the long metal wire member 10B is fed out. Further, in order to smoothly rotate the reel 32 around a certain rotation axis, a larger number of rollers may be provided around the collar portion. However, at the contact portion between the roller and the collar, dust attached to the collar or the like may fall off the roller. In order to prevent such dust from adhering to the long metal wire member 10 </ b> B, the roller is preferably provided on the lower half side of the reel 32.

  Moreover, the structure which supplies the metal wire elongate member 10B continuously is not restricted to the said example. For example, the reel may be arranged in a posture in which its central axis is along the vertical direction. In this case, the reel may rotate around the central axis to continuously supply the long metal wire member, or the reel may not rotate and the long metal wire member may wrap around the collar. However, the structure pulled out upward may be sufficient.

  The long metal wire member 10 </ b> B supplied from the reel is drawn into the second frame portion 24 through the partition plate 26 through the guide roller 36 as appropriate.

<About partition plate>
Since the long metal wire member 10B is drawn into the second frame portion 24 through the partition plate 26, the partition plate 26 needs to have a passage hole 26h through which the long metal wire member 10B passes. is there. As described above, in order to prevent the laser beam from the laser cutting device 80 from leaking to the first frame portion 22 side, it is necessary to make the through hole 26h formed in the partition plate 26 as small as possible. On the other hand, as will be described later, the feed mechanism 60 is configured to feed the long metal wire member 10B while moving it up and down, and accordingly, the long metal wire member 10B is also moved up and down. End up. For this reason, the passage hole 26h needs to be formed in such a size that it can pass even if the long metal wire member 10B moves up and down, which is contrary to the above requirement.

  Therefore, here, as shown in FIGS. 3 to 7, the following movable shielding mechanism 27 is incorporated in the partition plate 26.

  That is, the passage hole 26h formed in the partition plate 26 is a metal wire long member 10B (FIG. 4 and FIG. 4) that is positioned in the lower path when the metal wire long member 10B is fed by the feed mechanism unit 60. 5) and a long metal wire member 10B (see FIGS. 6 and 7) positioned in the upper path are formed to have a size that allows the passage.

  The movable shielding mechanism 27 includes a movable plate 27 </ b> B, a pair of rollers 27 a, a guide member 28, and a lift drive unit 29.

  The movable plate 27B is formed in a plate shape larger than the passage hole 26h. A passage hole 27Bh is formed at the center of the movable plate 27B so that the long metal wire member 10B can pass through as much as possible. That is, the passage hole 27Bh is formed to be the same as or larger (slightly larger) than the cross-sectional shape (cross-sectional shape in the direction orthogonal to the extending direction) of the long metal wire member 10B.

  The pair of rollers 27a is disposed on the one main surface side of the movable plate 27B and is rotatably disposed at the upper and lower positions of the passage hole 27Bh. A gap is formed between the pair of rollers 34a through which the long metal wire member 10B can pass. Here, the pair of rollers 34a has a configuration in which flanges are formed at both ends of a cylindrical body, and a gap through which the metal wire long member 10B can pass is provided between the pair of bodies.

  The movable plate 27B is supported by the guide member 28 so as to be movable up and down. That is, a pair of guide members 28 are fixed to both sides of the passage hole 26h on the surface of the partition plate 26 on the second frame portion 24 side, and both sides of the movable plate 27B are supported by the pair of guide members 28. Is supported so as to be movable up and down.

  In a state where the movable plate 27B is supported by the pair of guide members 28 so as to be movable up and down, the pair of rollers 27a is disposed in the passage hole 26h, and the pair of rollers 27a passes along with the vertical movement of the movable plate 27B. It moves up and down in the hole 26h. The movable plate 27B is formed in a size that can block the passage hole 27Bh even if it moves up and down.

  The elevating drive unit 29 includes an air cylinder, a hydraulic cylinder, a linear motor, a moving mechanism in which a motor is combined with a ball screw mechanism, and an actuator such as an electromagnetic actuator, and is configured to be able to drive the movable plate 27B up and down. Yes. And the raising / lowering drive part 29 drives the movable plate 27B up and down according to the timing at which the feed mechanism part 60 described later moves the metal wire long member 10B up and down. In addition, each drive part mentioned later is also comprised by actuators, such as an air cylinder, a hydraulic cylinder, a linear motor, the moving mechanism which combined the motor with the ball screw mechanism, and an electromagnetic actuator.

  That is, when the metal wire elongated member 10B supplied from the supply unit 30 passes through the passage hole 26h of the partition plate 26, the second frame portion passes between the pair of rollers 27a and the passage hole 26h of the movable plate 27B. 24 is led. Then, the movable plate 27B is moved upward by the elevating drive unit 29 in accordance with the upward movement of the long metal wire member 10B by the feed mechanism 60 described later (see FIGS. 6 and 7). In addition, the movable plate 27B is moved downward by the elevating drive unit 29 in accordance with the downward movement of the long metal wire member 10B by the feed mechanism 60. In any case, most of the passage hole 26h is kept closed by the movable plate 27B. Thereby, the external leakage of the laser beam from the second frame portion 24 is suppressed.

<Heating press mechanism>
FIG. 8 is a schematic front view showing the heating press mechanism unit 50, and FIG. 9 is a schematic side view showing the heating press mechanism unit 50.

  As shown in FIGS. 4, 8, and 9, the heating press mechanism 50 is provided in the second frame 24 and upstream of the feed mechanism 60. The hot press mechanism unit 50 joins metal wires to each other in the middle of the extending direction of the long metal wire member 10B to form the continuous joint 12B.

  Here, the heating press mechanism unit 50 includes a lower mold 52, an upper mold 54, and a lift drive unit 56.

  The lower mold 52 is a member that has a groove 52g that is open along the feed line L and that opens upward, and a part of the extending direction of the long metal wire member 10B is disposed in the groove 52g. It is heated and pressed.

  The upper die 54 has a press protrusion 54a that protrudes downward and can be disposed in the groove 52g.

  A heater H is incorporated in the lower mold 52 and the upper mold 54, and the heater H heats the inner surface of the groove 52g and the press protrusion 54a. The heating temperature is a temperature at which the surface of the metal wire (or plating when the metal wire is plated) can be melted at least on the outer periphery of the long metal wire member 10B.

  The elevating drive unit 29 drives the upper mold 54 up and down at a position above the lower mold 52.

  Then, with the upper mold 54 moved upward, a part of the extending direction of the metal wire long member 10B is disposed in the groove 52g. In this state, the upper die 54 is lowered by driving the elevating drive unit 29, and the press protrusion 54a is pushed into the groove 52g. Then, a part in the extending direction of the long metal wire member 10B disposed in the groove 52g is heated while being pressed by the press protrusion 54a. Thereby, in a part of the extending direction of the metal wire long member 10B, the outer periphery of the metal wire is melted and joined to each other at least at the outer periphery. At this time, in a part of the extending direction of the metal wire long member 10B, the metal wire may be joined only at the outer periphery, or all the metal wires may be melted and joined.

  Here, although the example in which the joining mechanism portion is the heating press mechanism portion 50 has been described, other joining mechanism portions such as an ultrasonic joining mechanism portion and a resistance welding mechanism portion may be applied.

<Feed mechanism>
FIG. 10 is a schematic side view showing the feed mechanism section 60, and FIG. 11 is a schematic plan view showing the feed mechanism section 60. The feed mechanism unit 60 sends the metal wire long member 10B supplied from the supply unit 30 while alternately repeating the operation of sending along the feed line L and the operation of stopping the feed (step (a)). It is configured as follows.

  More specifically, the feed mechanism unit 60 is provided along the feed line L between the hot press mechanism unit 50 and the laser cutting device 80. The feed mechanism unit 60 includes a placement support unit 62 and a feed support unit 70.

  The placement support portion 62 includes a placement plate portion 64 and a width direction clamping mechanism portion 66.

  The mounting plate portion 64 is an elongated plate-like member provided on the bottom surface extension of the groove 52g. Hole portions 64 h are formed at a plurality of locations along the extending direction of the mounting plate portion 64. The width of the hole 64h is set larger than the width of the long metal wire member 10B. In addition, a pair of convex portions 64 a is formed at each portion between the hole portions 64 h of the mounting plate portion 64. The pair of convex portions 64a is formed at a position close to the hole portion 64h, and a gap is provided between the hole portions 64h between the pair of convex portions 64a. The long metal wire member 10 </ b> B is supported by the pair of convex portions 64 a in a state of being lifted with respect to other portions of the upper surface of the mounting plate portion 64. And a lower one of a pair of vertical holding pieces 72b of the feed support portion 70 described later is a difference between the mounting plate portion 64 and the metal wire long member 10B between the pair of convex portions 64a. Is included.

  The width direction clamping mechanism 66 includes a pair of clamping members 67. The pair of clamping members 67 are disposed along the both sides of the hole 64h, which is the lower portion of the mounting plate portion 64. The pair of clamping members 67 have a plurality of widthwise clamping pieces 67P that protrude through the plurality of hole portions 64h and above the mounting plate portion 64, respectively.

  Further, the pair of clamping members 67 are supported by the guide member so as to be movable along the width direction of the mounting plate portion 64. Further, the pair of clamping members 67 are driven to move along the width direction of the mounting plate portion 64 by the width direction driving portion 68. The pair of clamping members 67P protruding from the holes 64h are opened and closed by moving the pair of clamping members 67 closer and away by the width direction driving unit 68. Accordingly, the long metal wire member 10B disposed on the placing plate portion 64 can be sandwiched by the pair of width direction sandwiching pieces 67P, or the sandwiched state can be released. Further, here, the width direction driving unit 68 drives and moves the pair of clamping members 67 via an elastic member 68a such as a spring. The elastic member 68a on each side of the pair of clamping members 67 is a member that exhibits the same elastic coefficient. For this reason, when a large force is applied to the pair of width-direction sandwiching pieces 67P when the pair of width-direction sandwiching pieces 67P grips the long metal wire member 10B, the width-direction driving unit 68 is driven to approach. The elastic member 68a is compressed and deformed, and further approach movement of the pair of widthwise holding pieces 67P is restricted. Thereby, the metal wire long member 10B is made as small as possible in the intermediate portion in the width direction of the mounting plate portion 64 while suppressing the application of a large compressive force in the width direction to the metal wire long member 10B. Can be aligned on a certain line.

  In addition, on the heating press mechanism unit 50 side of the mounting plate unit 64, the metal wire long member 10 </ b> B is attached to the heating press mechanism unit 50 at an upstream portion and a downstream portion of the feed line L with respect to the heating press mechanism unit 50. A pressing piece 64P for pressing toward the base is provided.

  The mounting support 62 is driven to move up and down between a lowered position on the bottom extension of the groove 52g and a raised position on the upper side thereof by a lifting drive section 69 constituted by an actuator together with a pair of clamping members 67. The

  The feed support unit 70 includes a pair of vertical clamping plate portions 72, an opening / closing drive unit 74 that moves the vertical clamping plate portion 72 closer to and away from the vertical clamping plate portion 72, and the vertical clamping plate portion 72 at a position above the mounting plate portion 64. A retreat drive unit 75 that reciprocates between the retreated position and a feed drive unit 76 that reciprocates the vertical clamping plate 72 along the feed line L is provided.

  The pair of vertically sandwiching plate portions 72 is configured such that a plurality of vertically sandwiching pieces 72b project in a comb-like shape along the horizontal direction with respect to the long substrate portion 72a along the feed line L. Yes. The vertical clamping piece 72b is provided between the pair of convex portions 64a of the mounting plate portion 64, and each width is set to be equal to or smaller than the distance between the pair of convex portions 64a. Yes. Further, the long metal wire member 10B on the mounting support 62 moved to the raised position is set to be disposed in the middle in the vertical direction of the vertical clamping piece 72b.

  The opening / closing drive unit 74 opens and closes the upper and lower vertical clamping pieces 72b by moving the pair of vertical clamping plates 72 close and apart. By closing the pair of upper and lower vertical holding pieces 72b, the metal wire long member 10B can be held from the upper and lower directions, and by opening the pair of upper and lower vertical holding pieces 72b, the metal wire long member 10B. Can be released.

  Further, the retreat drive unit 75 reciprocates the pair of vertical nipping plate portions 72 together with the opening / closing drive unit 74 between a nipping position above the mounting plate portion 64 and a position retreated to the side thereof. When the pair of vertical sandwiching plate portions 72 are moved to the retracted position by the retracting drive unit 75, the plurality of vertical sandwiching pieces 72b are moved from the upper side of the mounting plate portion 64 to the retracted position, and thus the metal wire The mounting support portion 62 that supports the long member 10B can be moved to the raised position. In this state, the retraction drive unit 75 moves the pair of vertical holding plate portions 72 to the holding position above the mounting plate portion 64, so that the lower one of the vertical holding pieces 72b It can be inserted between the mounting plate portion 64 and the metal wire long member 10B between the convex portions 64a, and the upper one can be disposed on the upper side. In this state, the metal wire long member 10B can be clamped from the vertical direction by the vertical clamping pieces 72b by driving the pair of vertical clamping plates 72 close to each other by driving the opening / closing drive unit 74. As a result, the long metal wire member 10 </ b> B is delivered from the mounting support portion 62 to the feed support portion 70.

  By operating in reverse to the above, the long metal wire member 10 </ b> B can be delivered from the feed support portion 70 to the placement support portion 62.

  Further, with the feed support portion 70 supporting the long member 10B made of metal wire, the feed drive portion 76 moves the pair of vertical clamping plate portions 72 along the feed line L together with the opening / closing drive portion 74 and the retracting drive portion 75. Then, the metal wire elongated member 10B is sent along the feed line L to the downstream side. When the feed drive unit 76 finishes feeding, the feeding of the long metal wire member 10B is also stopped.

  That is, the main feed mechanism 60 delivers the long metal wire member 10B from the mounting support 62 to the feed support 70, and feeds the long metal wire 10B by the feed support 70. By repeating the delivery of the long wire member 10B from the feed support portion 70 to the mounting support portion 62, the operation of feeding the long metal wire member 10B along the feed line L and the feed are stopped. Sending while repeating the operation alternately.

  This operation will be described later in detail in relation to other processing.

The cutting support clamping unit 40 includes a clamping claw 42 that is opened and closed by driving of an actuator, and a lifting drive unit 44 that moves the clamping claw 42 up and down in accordance with the up and down movement of the mounting support unit 62 described above. Then, at the timing when the long metal wire member 10B is sent, the holding by the holding claws 42 is released, and at other timings, particularly when the laser cutting device 80 cuts the long metal wire member 10B, the metal The long wire member 10B is clamped.

  The laser cutting device 80 is configured to be capable of cutting the continuous joint portion 12B of the long metal wire member 10B at the intermediate portion in the extending direction downstream of the feed line L.

  The laser cutting device 80 emits a laser beam from the nozzle 82 of the head 81, and irradiates the continuous bonding portion 12B with the laser beam to cut the laser beam. The wavelength of the laser light is not particularly limited as long as the continuous joint 12B can be cut.

  The head 81 is provided on the downstream side of the feed line L with respect to the cutting support clamping unit 40, and is supported by a drive unit 84 including two actuators so as to be movable up and down and horizontally. When sending the long metal wire member 10B, the head 81 is retracted to a position above the long metal wire member 10B and away from the top. When the continuous joint 12B is cut while the long metal wire member 10B is stopped, the drive is driven to move to a position on the central portion in the extending direction of the continuous joint 12B. Is done. And the laser beam cut | disconnects the extending direction center part of the continuous junction part 12B by moving the nozzle 82 across the extending direction center part of the continuous junction part 12B by the drive of the drive part 84.

  When the long metal wire member 10B is sent beyond the cutting work site by the laser cutting device 80, the end of the long metal wire member 10B is held by the holding claws 92 of the holding pin 90 for recovery. The When the continuous joint 12B is cut in this state, the conductive member 10 having the joints 12 formed at both ends is manufactured. The conductive member 10 is moved to a position away from the cutting support clamping unit 40 by driving of the recovery driving unit 94 in a state of being clamped by the clamping claws 92 of the recovery clamping unit 90. A recovery box 96 is provided below the moving position, and when the nipping by the nail 92 of the collection nipping portion 90 is released at the movement destination, the conductive member 10 is collected in the collection box 96. .

<About the operation of the conductive member manufacturing apparatus>
The operation of each part of the conductive member manufacturing apparatus 20 is controlled by the control unit 98. The control unit 98 is a general microcomputer including a CPU, a ROM, a RAM, and the like, and controls the operation of the manufacturing apparatus 20 according to a software program stored in advance. In particular, here, in the control unit 98, the heating press mechanism unit 50 forms the continuous joint 12 </ b> B in a state where the feed mechanism unit 60 stops the operation of feeding the long metal wire member 10 </ b> B along the feed line L. Operation control is performed so that both the processing and the processing in which the laser cutting device 80 cuts the continuous joint 12B are performed. It should be noted that some or all of the functions performed by the control unit 98 may be realized by hardware using a dedicated logic circuit or the like.

  FIG. 14 is a flowchart showing a processing example in the control unit 98. The operation of the manufacturing apparatus 20 will be described with reference to this flowchart. In each figure shown in FIG. 15 and subsequent figures, for convenience of explanation, each part is depicted in a simplified manner as compared with FIG. 3, and the number of vertical holding pieces 72b and width holding pieces 67P is the same as in FIG. Absent.

  First, in an initial state, as shown in FIGS. 15 and 16, the long metal wire member 10 </ b> B drawn from the reel 32 is guided into the second frame portion 24, and the upper die 52 and the placement support portion 62 are It is assumed that the end portion is sandwiched by the cutting support sandwiching portion 40. It is assumed that continuous joints 12B are formed on the long metal wire member 10B at regular intervals, and joints 12 are formed at the ends. In this state, the upper die 54 is at a position away from the lower die 52, the placement support portion 62 is at the lowered position, and the feed support portion 70 is separated from above the placement support portion 62. Suppose that it is in the retreated position. In addition, it is assumed that the pair of width direction holding pieces 67P holds the long metal wire member 10B on the mounting support portion 62 from the width direction. The head 81 is at a position retracted away from the end of the long metal wire member 10B.

  When a production start command is given to produce the conductive member 10, a feed command is given from the control unit 98 in step S1. Then, as shown in FIG. 17, the mounting support portion 62 is raised by driving the elevating drive portion 69, and the long metal wire member 10 </ b> B is disposed at a position between the vertical holding pieces 72 b. As described above, at this time, the movable plate 27 </ b> B is lifted by the drive of the lift drive unit 29. In each operation to be described later, the movable plate 27B is raised when the placement support portion 62 is raised, and the movable plate 27B is lowered when the placement support portion 62 is lowered.

  Thereafter, as shown in FIG. 18, by driving the retracting drive unit 75, the vertical clamping piece 72 b moves forward, and the vertical clamping piece 72 b is made of a metal wire long between the widthwise clamping pieces 67 </ b> P. The member 10B is sandwiched from above and below.

  Then, as shown in FIGS. 19 and 20, the driving in the width direction driving unit 68 opens the width direction holding piece 67 </ b> P to release the holding of the metal wire long member 10 </ b> B. As a result, the mounting support portion 62 moves downward. Subsequently, by driving the feed driving unit 76, the vertical clamping piece 72 b moves downstream along the feed line L, so that the long metal wire member 10 </ b> B is sent downstream along the feed line L. . The distance that the feed driving unit 76 sends the vertical holding pieces 72b is an integral multiple (here, 1 time) of the pitch of the plurality of widthwise holding pieces 67P along the feed line L.

  Thereafter, as shown in FIG. 21, the mounting support portion 62 is moved upward by driving the elevating drive portion 69, and the width direction sandwiching piece 67 </ b> P is configured to widen the long metal wire member 10 </ b> B by driving the width direction driving portion 68. Hold in the direction. In addition, after the end of the feeding of the long metal wire member 10B, the first continuous joint portion 12B and the second continuous joint portion from the end of the long metal wire member 10B are held by the cutting support clamping portion 40. The metal wire long member 10B is sandwiched between 12B.

  Next, as shown in FIG. 22, the metal wire elongated member 10 </ b> B is released from the vertical holding by the vertical holding pieces 72 b by driving the opening / closing driving unit 74, and then moved up and down by driving the retraction driving unit 75. The direction clamping piece 72b is retracted.

  Then, as shown in FIG. 23, the placement support unit 62 is lowered by driving the lifting drive unit 69. Then, a part of the extending direction of the metal wire long member 10B is disposed in the groove 52g of the lower mold 52, and the metal line long member 10B is located on the downstream side of the feed line L from the groove 52g. The portion is disposed on the bottom surface extension of the groove 52g and disposed at a position where laser cutting is possible.

  As described above, a series of processing for sending is completed. If it is determined in step S2 that the processing for feeding has been completed, the process proceeds to step S3, and a heating press command and a cutting command are given.

  Then, as shown in FIG. 24, the upper die 54 is lowered by driving the elevating drive unit 56, and the metal wire long member 10B disposed in the groove 52g is heated and pressed. Thereby, the continuous joining part 12B is formed in a part of the extending direction of the metal wire long member 10B (step (b)). Further, the drive unit 84 moves the head 81 of the laser cutting device 80 to a position above the continuous joint 12B that is closest to the end of the long metal wire member 10B, and irradiates the laser beam from the nozzle 82. However, the continuous joint 12B moves so as to cross the continuous joint 12B at the center in the extending direction. Thereby, the continuous joining part 12B is cut | disconnected (process (c)), and the electrically-conductive member 10 in which the joining part 12 was formed in both ends is formed.

  Thereafter, as shown in FIG. 25, the upper die 54 is raised by driving the elevating drive unit 56. Further, the head 81 of the laser cutting device 80 is moved to the retracted position by the drive unit 84. Further, the cut conductive member 10 is clamped by the recovery clamping unit 90, and the clamping of the conductive member 10 is released in a state where the recovery clamp unit 90 is moved to a position above the recovery box 96. Then, the conductive member 10 is collected in the collection box 96.

  In next step S4, it is determined whether or not the production is finished, that is, whether or not the production of the preset number of conductive members 10 is finished. If it is not judged that the production is finished, the process returns to step S1 and the above processing is repeated. . When it is determined that the production is finished, the process is finished.

<Effects>
According to the conductive member manufacturing apparatus and the conductive member manufacturing method configured as described above, in the state where the feed mechanism section 60 stops the operation of feeding the long metal wire member 10B along the feed line L, the heating press Since the mechanical part 50 performs both the process of forming the continuous joining part 12B and the process of the laser cutting device 80 cutting the continuous joining part 12B, the metal wire is joined at both ends from the long metal wire member 10B. Thus, the plurality of conductive members 10 in which the joint portions 12 are formed can be efficiently manufactured.

  Moreover, since the joining mechanism part is the heating press mechanism part 50 and the cutting mechanism part is the laser cutting device 80, the continuous joining part is in a state where the residual heat from the heating press mechanism part 50 remains in the continuous joining part 12B. 12B can be cut with a laser beam. That is, the cutting with the laser beam can be performed in a state where the continuous bonding portion 12B is heated to a temperature higher than room temperature. For this reason, the cutting | disconnection by a laser beam can be performed rapidly, or the cutting | disconnection by a laser beam with small output is attained.

  Further, since the heat insulating plate member 23 is provided between the heating press mechanism unit 50 and the laser cutting device 80, the heat generated by the heating press mechanism unit 50 is difficult to be transmitted to the laser cutting device 80 side. The distortion due to the heating of the optical system at 80 is suppressed, and a stable quality laser beam can be emitted.

  Further, since the feed mechanism section 60 is provided between the heating press mechanism section 50 and the laser cutting device 80, the state in which the long metal wire member 10B is stopped by the feed mechanism section 60 is the heating press mechanism. It is easy to keep in both the unit 50 and the laser cutting device 80. For this reason, accurate hot pressing and cutting can be performed.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
