{Embodiment}
Hereinafter, the terminal conveyance device 40 according to the embodiment will be described. The terminal transport device 40 is a device that transports the strip-attached terminal 91 cut out from the continuous terminal 90 in which a plurality of terminals 94 are connected by a chain strip 92. Here, the terminal conveying device 40 is described as being incorporated in the terminal crimping device 10 and conveying the terminal 94 to the crimping mechanism 70 also incorporated in the terminal crimping device 10. Moreover, the terminal crimping apparatus 10 is demonstrated as what is integrated in the cutting pressure apparatus which manufactures the electric wire with a terminal of predetermined length from the elongate electric wire 80. FIG.

Here, the cutting device will be described as a device that is used in a manufacturing method in which a plurality of types of terminal-attached electric wires included in the wire harness are manufactured together in one device for each unit of the wire harness. Such a manufacturing method is sometimes referred to as a set method.

In this set construction method, depending on the wire harness, a plurality of types of electric wires with terminals to which different types of terminals 94 are attached may be manufactured with one apparatus. In that case, the terminal transport apparatus 40 is also required to transport a plurality of types of strip-attached terminals 91 with one apparatus. In this case, when the pair of gripping claws 46 grip the strip 93 from the terminal 94 side of the strip-attached terminal 91 and transport the strip-attached terminal 91, depending on the shape of the terminal 94, There is a possibility that the connecting portion 96 or the like connected to the counterpart conductor interferes with the gripping claws 46. In order to avoid such a situation, the terminal conveying device 40 according to the embodiment is incorporated in the terminal crimping device 10 of the cutting device.

Here, the continuous terminal 90 will be described with reference to FIG. FIG. 1 is a plan view showing the continuous terminal 90.

The continuous terminal 90 is a band-shaped member in which a plurality of terminals 94 are connected. Specifically, a plurality of terminals 94 are chained in parallel at equal intervals on one side of the band-shaped chain band 92. . The base part of each terminal 94 on the side of the chain band 92 is formed to be open in a substantially U-shaped cross section so that it can be crimped to the end of the electric wire 80, and constitutes a crimping part 95. The crimping portion 95 may be referred to as a barrel portion 95. In addition, each terminal 94 includes a connection portion 96 that is connected to the tip of the barrel portion 95. The connection part 96 is a part connected to the counterpart conductor. Here, the connection portion 96 is formed in a so-called female shape having a casing shape, but this is not essential. For example, the connection portion may be formed in a male shape such as a pin shape, or may be formed in a shape in which a hole through which a bolt passes is formed while being formed in a flat plate shape. Further, here, feed holes 92 h are formed in the chain band 92 at equal intervals corresponding to the respective terminals 94. The feed hole 92h is formed in a portion of the chain band 92 where the base end portion of the terminal 94 protrudes, but may be formed between the terminals 94 in the chain band 92.

As will be apparent later, the chain band 92 is cut between the terminals 94, so that one terminal 94 at the end of the continuous terminal 90 is stripped 93 corresponding to the one terminal 94 (cutout). In this state, it is disconnected from the continuous terminal 90 while being connected to the connected chain band 92). Hereinafter, the terminal 94 with the strip 93 is also referred to as a strip-attached terminal 91. Here, the chain strip 92 is cut so that the terminal 94 is positioned on one end side in the extending direction of the strip 93 with respect to the strip 93. More specifically, when the strip-attached terminal 91 is cut out from the continuous terminal 90, the downstream strip 93 is elongated, that is, the terminal 94 is linked to the upstream side with respect to the strip 93. The band 92 is cut. However, the chain band 92 may be cut so that the terminal 94 is located downstream or centered with respect to the strip 93. Hereinafter, the side of the strip 93 where the terminal 94 is located may be referred to as one end portion 93a, and the opposite side may be referred to as the other end portion 93b.

The configuration of the terminal crimping apparatus 10 will be described with reference to FIG. FIG. 2 is a diagram schematically illustrating the configuration of the terminal crimping device 10.

The terminal crimping device 10 includes a plurality (here, three) of terminal feed mechanisms 20, a plurality (here, three) of cutting mechanisms 30, a terminal transport device 40, a crimping mechanism 70, and a control unit 100. Is provided.

The terminal feed mechanism 20 feeds the continuous terminals 90 toward the front end side in the extending direction of the chain band 92 by one terminal 94 at a time. Specifically, the terminal feed mechanism 20 includes, for example, a long stage 22 on which the continuous terminals 90 are placed, and a drive mechanism that sends out the continuous terminals 90 on the stage 22 one by one. be able to. Specifically, the drive mechanism can be configured to include, for example, a claw portion that is caught in the feed hole 92h and a claw portion drive portion that moves the claw portion in the feed direction. Further, the drive mechanism may include, for example, a roller that sends out the continuous terminal 90 by rotating while contacting the continuous terminal 90 on the stage 22 and a drive unit that rotationally drives the roller.

In the following, the plane shown in FIG. 2 is the xy plane, the direction in which the continuous terminal 90 is sent by the terminal feed mechanism 20 in the xy plane is the x-axis direction, and the direction orthogonal to the x-axis direction is the y-axis direction. To do. At this time, the direction in which the continuous terminal 90 is fed is the positive direction in the x-axis direction, and the side where the terminal 94 is positioned with respect to the strip 93 is the positive direction in the y-axis direction. In the following description, the xy plane is a plane extending in the horizontal direction, and the direction orthogonal to the xy plane is the vertical direction.

Each cutting mechanism 30 cuts the chain band 92 of the continuous terminals 90 between the terminals 94 to cut out one strip-attached terminal 91 from the continuous terminals 90. Specifically, the cutting mechanism 30 includes, for example, a cutter, a drive mechanism that moves the cutter in the direction of approaching and separating from the chain band 92, and the like.

The terminal conveyance device 40 conveys the strip-attached terminals 91 sent to the starting position P1 one after another to the predetermined target position P3. The terminal transport device 40 includes a first transport mechanism 42 and a second transport mechanism 60 provided between the starting position P1 and the target position P3.

The first transport mechanism 42 and the second transport mechanism 60 transport the strip-attached terminal 91 from each starting position P1 to the target position P3. That is, the delivery position P2 is provided between the starting position P1 and the target position P3, and the first transport mechanism 42 transports the strip-attached terminal 91 from the starting position P1 to the delivery position P2, and the second The transport mechanism 60 receives the strip-attached terminal 91 from the first transport mechanism 42 at the delivery position P2, and transports the strip-attached terminal 91 to the target position P3. Specific configurations of the first transport mechanism 42 and the second transport mechanism 60 will be described later.

Here, as the starting position P1, for example, each of the plurality of terminal feed mechanisms 20 may be set, or may be set to one position different from the plurality of terminal feed mechanisms 20. In the former case, it is conceivable that the first transport mechanism 42 is provided so as to be movable to the starting position P1 set in each of the plurality of terminal feed mechanisms 20. In this case, after the first transport mechanism 42 grips the chain band 92, the cutting mechanism 30 may cut the chain band 92 and cut the strip-attached terminal 91 from the continuous terminal 90. In the latter case, a transfer mechanism is provided that selects one terminal feed mechanism 20 among the plurality of terminal feed mechanisms 20 and transports the strip-attached terminal 91 cut out from the terminal feed mechanism 20 to one starting position P1. It is possible.

At the target position P3, the crimping mechanism 70 cuts off the strip 93 of the strip-attached terminal 91 sent out from the terminal 94 and crimps the barrel portion 95 of the terminal 94 separated from the strip 93 with a mold. As a result, the barrel portion 95 is fixed by crimping to the end portion of the electric wire 80 (see FIGS. 6 and 7). Thereby, the terminal 94 is fixed to the end part of the electric wire 80, and the electric wire with a terminal is manufactured. Specifically, the crimping mechanism 70 is an upper mold 72 for crimping, a lower mold 74 for crimping disposed opposite to the upper mold 72, and a direction in which the upper mold 72 and the lower mold 74 are moved closer to and away from each other. The drive mechanism 76 etc. to be moved are included. At this time, the direction in which the two

molds

72 and 74 approach and separate is the crimping direction. Here, the upper mold 72 and the lower mold 74 are closely spaced along a direction orthogonal to the xy plane. The drive mechanism 76 lowers the upper mold 72 toward the lower mold 74 via the ram member 78 attached to the upper mold 72, so that the barrel of the terminal 94 placed on the lower mold 74. The part 95 is crimped onto the electric wire 80.

At this time, the crimping mechanism 70 includes a pressing portion 79 which is a part of a separation mechanism for separating the terminal 94 from the strip 93 at the time of crimping. The pressing portion 79 is also driven along the direction orthogonal to the xy plane by the driving mechanism 76 via the ram member 78. As will be described in detail later, the pressing portion 79 presses the holding portion 62 at the target position P3 to shear the strip-attached terminal 91 at the connecting portion between the strip 93 and the terminal 94.

The control unit 100 is electrically connected to and controls each of the plurality of terminal feeding mechanisms 20, the cutting mechanism 30, the terminal conveying device 40, and the crimping mechanism 70. Specifically, the control unit 100 includes, for example, a CPU that performs various arithmetic processes, a ROM that stores programs, a RAM that serves as a work area for arithmetic processes, a hard disk that stores programs and various data files, a LAN, and the like. A data communication unit having a data communication function is connected to each other by a bus line or the like, and is configured by a general computer. The control unit 100 is connected to an input unit composed of a display for performing various displays, a keyboard, a mouse, and the like.

The outline of the operation of the terminal crimping apparatus 10 will be described with continued reference to FIG. However, a series of operations executed by the terminal crimping device 10 is performed under the control of the control unit 100.

Each of the plurality of terminal feeding mechanisms 20 sends out the continuous terminal 90 by one terminal 94. Here, for example, it is assumed that each of the plurality of terminal feeding mechanisms 20 sends out different types of continuous terminals 90.

The cutting mechanism 30 cuts the strip-attached terminal 91 from the continuous terminal 90 sent by the terminal feeding mechanism 20. Specifically, the chain 94 is cut between the terminal 94 located at the tip of the continuous terminals 90 sent by the terminal feeding mechanism 20 and the terminal 94 located next to the upstream side of the terminal 94, A strip-attached terminal 91 is formed.

The terminal conveying device 40 conveys the strip-attached terminals 91 sent to the starting position P1 one after another to the target position P3. Specifically, the terminal conveyance device 40 causes the strip-attached terminal 91 cut out from the continuous terminal 90 sent out by any one of the plurality of terminal feed mechanisms 20 from the starting position P1. Transport to the target position P3. By repeating this, the first to third strip-attached terminals 91 of different types are successively sent to the target position P3. At this time, it is set as appropriate as to which terminal feeding mechanism 20 to which the strip-attached terminal 91 is transported. For example, it may be set by a production plan table read by the control unit 100 or the like, or set so as to convey the strip-attached terminals 91 sent from the first to third terminal feed mechanisms 20 in order. Also good.

The crimping mechanism 70 separates the strip 93 of the strip-attached terminal 91 sent to the target position P3 from the terminal 94, and the barrel portion 95 of the terminal 94 separated from the strip 93 to the end of the electric wire 80. Crimp and fix. The type of the electric wire 80 to which the terminal 94 of the first to third strip-attached terminals 91 is crimped is appropriately set. For example, the electric wires 80 to which the terminals 94 of the first to third strip-attached terminals 91 are respectively crimped may be the same or at least partially different. Moreover, even if it is the same kind of terminal 91 with a strip, the kind of the electric wire 80 crimped | bonded may differ. Depending on the combination of the terminal 94 and the electric wire 80, different types of electric wires with terminals are successively produced one after another.

Thus, since the terminal crimping apparatus 10 can continuously manufacture different types of terminal-attached electric wires, it can comply with the above set method. However, in the terminal crimping apparatus 10, it is not always necessary to continuously manufacture different types of electric wires with terminals, and the same types of electric wires with terminals may be manufactured continuously.

<Terminal conveying device 40>
The configuration of the terminal transport device 40 will be described with reference to FIGS. FIG. 3 is a plan view schematically showing the configuration of the first transport mechanism 42. FIG. 4 is a perspective view showing the gripping claw 46. FIG. 5 is a plan view schematically showing the configuration of the second transport mechanism 60.

The first transport mechanism 42 receives the strip-attached terminal 91 at the starting position P1, and repeatedly performs the transport operation of transporting the received strip-attached terminal 91 to the delivery position P2. Here, the first transport mechanism 42 receives the strip-attached terminal 91 in the posture in which the extending direction of the strip 93 of the strip-attached terminal 91 is along the x-axis direction at the starting position P1, and at the delivery position P2. The strip-attached terminal 91 is transferred to the second transport mechanism 60 in a posture in which the extending direction of the strip 93 of the strip-attached terminal 91 is along the y-axis direction. Specifically, the first transport mechanism 42 includes a grip portion 44 that grips the strip-attached terminal 91 and a grip portion moving mechanism 50 that moves the grip portion 44.

The grip portion 44 is configured to be able to grip and release the strip-attached terminal 91. Specifically, the gripping portion 44 has a pair of gripping claws 46 disposed so as to face each other with the flat gripping surfaces 46f parallel to each other, and a direction in which the pair of gripping portions 44 are moved closer to and away from each other (that is, a pair of facing grips). And a driving unit that moves the gripping surface 46f in a direction in which the gripping surface 46f approaches and separates. For example, a solenoid or an air cylinder is used as the drive unit.

The pair of gripping claws 46 grip the first portion of the strip 93 of the strip-attached terminal 91. The pair of gripping claws 46 are provided such that the tips of the pair of gripping claws 46 have a gap in the middle portion while gripping the strip 93 of the terminal 91 with the strip. More specifically, the gripping direction of the pair of gripping claws 46 (the direction in which the pair of gripping claws 46 approach and separate from each other) is set here in a direction orthogonal to the xy plane. The grip surface 46f is set parallel to the xy plane. And the front-end | tip part 46a in which the holding surface 46f is provided in the holding claw 46 protrudes in the holding | gripping direction toward the other party's holding claw 46 with respect to the intermediate part 46b. As a result, the intermediate portion 46 b of the gripping claw 46 is spaced with the tip portion 46 a gripping the strip 93. The space located between the intermediate portions 46b is the gripping direction of the terminal 94 when the tip 94a of the gripping claw 46 grips the strip 93 from the terminal 94 side and the width of the terminal 94 is large. When viewed from the side, this is an accommodation space in which a portion overlapping the intermediate portion 46b of the gripping claw 46 is accommodated. Therefore, the interval is preferably set to be equal to or greater than the height dimension (here, the dimension along the direction orthogonal to the xy plane) of the portion of the terminal 94 that may be accommodated in the accommodation space. Furthermore, the interval is more preferably set to be equal to or greater than the maximum height dimension of the terminal 94.

The gripper moving mechanism 50 includes a gripper linear movement mechanism 52 that moves the gripper 44 linearly, and a gripper rotation mechanism 54 that rotates the gripper 44. More specifically, here, the grip portion 44 is rotatably attached to the attachment portion 48 and is provided so as to be linearly movable via the attachment portion 48.

The gripping part linear movement mechanism 52 is configured by a linear actuator such as an air cylinder or a linear motor. The gripping part 44 is moved to a first position corresponding to the starting position P1 and a second position corresponding to the delivery position P2. Drive back and forth between positions. Here, the gripping portion linear movement mechanism 52 drives the attachment portion 48 to reciprocate between the first position and the second position. More specifically, here, the gripper linear movement mechanism 52 moves the gripper 44 along the x-axis direction.

The gripping part rotation mechanism 54 is constituted by, for example, a motor or the like, and the gripping part 44 is placed between a first posture corresponding to the posture at the time of reception and a second posture corresponding to the posture at the time of delivery. To rotate. Here, the description will be made assuming that the gripping part rotation mechanism 54 rotates the gripping part 44 by 90 degrees with respect to the attachment part 48 on the xy plane. But the rotation angle of the holding part 44 by the holding part rotation mechanism 54 is not restricted to 90 degree | times, It may be less than 90 degree | times and may be larger than 90 degree | times. The rotation angle of the gripping portion 44 by the gripping portion rotating mechanism 54 is determined by the direction in which the strip 93 extends and the holding portion 62 when the terminal 91 with the strip is delivered to the holding portion 62 described later of the second transport mechanism 60. It may be determined so that the moving direction matches. Here, since the moving direction of the holding portion 62 is set in the y-axis direction, the extending direction of the strip 93 of the strip-attached terminal 91 is attached in the posture along the y-axis direction at the delivery position P2. The terminal 91 is transferred to the second transport mechanism 60. At this time, since the extending direction of the strip 93 of the strip-attached terminal 91 is received along the x-axis direction at the starting position P1, the strip-attached terminal 91 is received by the gripper rotating mechanism 54. The rotation angle is set to 90 degrees.

Here, in the state where the extending direction of the strip 93 of the terminal 91 with the strip is in the posture along the y-axis direction at the delivery position P2, the terminal 94 is in the x-axis direction with respect to the strip 93. The strip-attached terminal 91 is transferred to the second transport mechanism 60 in a posture positioned on the negative side. At this time, the terminal 94 is on the positive side in the y-axis direction with respect to the strip 93 in a state where the extending direction of the strip 93 of the terminal 91 with the strip is along the x-axis direction at the starting position P1. In order to receive the strip-attached terminal 91 in the positioned posture, the grip portion 44 is rotated 90 degrees counterclockwise in FIG.

When gripping an object with the gripping portion 44, the gripping portion moving mechanism 50 places the gripping portion 44 in a state where the pair of gripping claws 46 are separated, and at least a part of the target object is disposed between the pair of gripping surfaces 46f. Move to such a position. And a drive part moves the holding part 44 to the direction which mutually approaches. Accordingly, at least a part of the object is sandwiched between the pair of gripping surfaces 46f (that is, at least a part of the object is gripped by the grip part 44). As a result, the object is gripped by the grip portion 44. Further, when the gripping unit 44 releases the gripping of the object, the driving unit moves the pair of gripping claws 46 in a direction away from each other. As a result, the pair of gripping surfaces 46f are separated from the object, and the gripping of the object by the pair of gripping claws 46 is released.

The object to be gripped by the grip portion 44 is the strip-attached terminal 91, and the grip portion 44 grips the strip 93 of the strip-attached terminal 91 as shown in FIGS. Thus, the strip-attached terminal 91 is gripped. Here, as shown in FIG. 3, the grip portion 44 grips a portion (first portion) of the strip 93 of the strip-attached terminal 91 excluding the portion where the terminal 94 protrudes. At this time, the portion (second portion) from which the terminal 94 protrudes in the strip 93 is held by the second transport mechanism 60 that receives the terminal 94 from the first transport mechanism 42. Thereby, the terminal 94 and the strip 93 can be separated while the strip-attached terminal 91 is held by the second transport mechanism 60. Here, since the part from which the terminal 94 protrudes in the strip 93 is provided in the one end side portion 93a of the strip 93, the grip portion 44 grips the other end side portion 93b of the strip 93, and the second transport mechanism. 60 grips one end portion 93 a of the strip 93.

The second transport mechanism 60 receives the strip-attached terminal 91 from the first transport mechanism 42 at the delivery position P2, and repeatedly performs the transport operation of transporting the received strip-attached terminal 91 to the target position P3. . Here, as described above, the second transport mechanism 60 places the strip-attached terminal 91 in the posture in which the extending direction of the strip 93 of the strip-attached terminal 91 is along the y-axis direction at the delivery position P2. Receive from the transport mechanism 42. Then, the second transport mechanism 60 transports the strip-attached terminal 91 to the target position P3 in a posture in which the extending direction of the strip 93 of the strip-attached terminal 91 is along the y-axis direction. Specifically, the second transport mechanism 60 includes a holding unit 62 that holds the strip-attached terminal 91 and a holding unit moving mechanism 66 that reciprocates the holding unit 62 between the delivery position P2 and the target position P3. Prepare.

The holding part 62 is formed in a substantially rectangular parallelepiped shape. The holding portion 62 is formed with a gripping claw recess 63a in a manner in which one corner is recessed in a plan view. The tip of the gripping claw 46 that grips the other end portion 93b of the strip 93 of the strip-attached terminal 91 is positioned in the gripping claw concave portion 63a at the time of delivery, so that the one end side portion 93a of the strip 93 is provided. The portion from which the terminal 94 protrudes overlaps the holding portion 62 in plan view. Thereby, the holding part 62 can hold the portion of the strip 93 from which the terminal 94 protrudes.

Further, a guide recess 63b that is recessed in a curved shape (here, in an arc shape) toward the lower surface is formed on the upper surface of the holding portion 62. The guide recess 63 b is formed in an intermediate portion along the moving direction of the holding portion 62 (here, the y-axis direction) on the upper surface of the holding portion 62. The central axis direction with respect to the arc of the guide recess 63b is set to a direction orthogonal to the moving direction of the holding portion 62, that is, the x-axis direction. An electric wire 80 is placed on the guide recess 63b during the crimping.

The holding unit moving mechanism 66 is configured by a linear actuator such as an air cylinder or a linear motor, and reciprocates the holding unit 62 between the delivery position P2 and the target position P3. Here, the holding part moving mechanism 66 reciprocates the holding part 62 along the y-axis direction.

The holding part 62 also serves as a part of a separation mechanism for separating the terminal 94 from the strip 93 at the time of crimping. Specifically, for example, the holding portion 62 is attached to the slider member via an elastic member 64 such as a spring that expands and contracts in a direction orthogonal to the xy plane. The slider member is driven along the y-axis direction by the holding unit moving mechanism 66. Then, the holding member 62 reaches the target position P3 by the slider member being transported to the target position P3 by the holding unit moving mechanism 66. In this state, the holding portion 62 is pressed in a direction orthogonal to the xy plane by the pressing portion 79 of the crimping mechanism 70, and the holding portion 62 moves relative to the lower mold 74 in a direction orthogonal to the xy plane. As a result, the strip 93 moves in a direction perpendicular to the xy plane with respect to the terminal 94, and the strip-attached terminal 91 is held on the holding portion 62 and the terminal placed on the lower mold 74. It shears in the connection part with 94 (refer FIG.6 and FIG.7).

<Operation of Terminal Transport Device 40>
The operation of the terminal conveying device 40 will be described with reference to FIGS. 6 to 8 in addition to FIGS. 6 and 7 are diagrams for explaining the state of strip separation and terminal crimping. FIG. 8 is a flowchart showing the flow of operations performed by the terminal transport device 40 for one strip-attached terminal 91.

First, in step S1, preparation is made to receive the strip-attached terminal 91 sent to the starting position P1. Specifically, the first transport mechanism 42 moves the grip portion 44 in a state in which the pair of grip claws 46 are separated to the starting position P1 by the grip portion linear movement mechanism 52 and the grip portion rotation mechanism 54. At this time, the gripping portion 44 is moved so that the strip 93 is positioned between the pair of gripping claws 46 separated from each other. Here, the grip portion 44 is moved so that the other end portion 93b of the strip 93 is positioned between the pair of grip surfaces 46f. At this time, the gripping portion 44 is set to be able to grip the strip 93 from the side where the terminal 94 is located. At this time, the position of the terminal 91 with the strip with respect to the holding portion 62 is changed by adjusting the position where the grip portion 44 grips the strip 93. This will be described in detail later.

In the next step S2, the strip-attached terminal 91 at the starting position P1 is received. Specifically, the pair of grip claws 46 are brought close to each other, and the strip 93 positioned between the pair of grip claws 46 is gripped by the pair of grip claws 46. As a result, the other end portion 93b of the strip 93 is gripped by the grip portion 44, and the strip-attached terminal 91 at the starting position P1 is gripped by the grip portion 44. At this time, even if the intermediate portion 46 b of the gripping claw 46 and the terminal 94 overlap when viewed from the gripping direction, the overlapping portion of the terminal 94 is provided between the intermediate portions 46 b of the pair of gripping claws 46. Fits into the designated storage space. Thereby, interference with the holding claw 46 and the terminal 94 is suppressed.

In the next step S3, preparations for delivering the strip-attached terminal 91 from the first transport mechanism 42 to the second transport mechanism 60 are made. Specifically, the first transport mechanism 42 moves the grip portion 44 in a state of gripping the strip-attached terminal 91 to the delivery position P 2 by the grip portion linear movement mechanism 52 and the grip portion rotation mechanism 54. Thereby, the strip-attached terminal 91 is transferred to the delivery position P2. At this time, the second transport mechanism 60 moves the holding portion 62 in a state where the strip-attached terminal 91 can be received to the delivery position P 2 by the holding portion moving mechanism 66. As a result, the tip of the gripping claw 46 is positioned in the gripping claw recess 63a of the holding portion 62 so that the extending direction of the strip 93 gripped by the gripping portion 44 is along the y-axis direction. The side portion 93a can be held by the holding portion 62.

Here, after the gripping portion 44 is rotated by the gripping portion rotating mechanism 54, the gripping portion 44 is linearly moved by the gripping portion linear movement mechanism 52. However, this is not essential. For example, after the gripper 44 is linearly moved by the gripper linear movement mechanism 52, the gripper 44 may be rotated by the gripper rotation mechanism 54. Further, for example, the linear movement of the grip portion 44 by the grip portion linear movement mechanism 52 and the rotation of the grip portion 44 by the grip portion rotation mechanism 54 may be performed simultaneously.

In the next step S4, the strip-attached terminal 91 is delivered from the first transport mechanism 42 to the second transport mechanism 60. Specifically, after the holding portion 62 of the second transport mechanism 60 grips the one end side portion of the strip-attached terminal 91, the grip portion 44 releases the grip of the strip-attached terminal 91. As a result, the strip-attached terminal 91 is delivered from the first transport mechanism 42 to the second transport mechanism 60 at the delivery position P2.

In the next step S5, crimp preparation is performed. Specifically, the second transport mechanism 60 moves the holding unit 62 holding the strip-attached terminal 91 to the target position P3.

In the next step S6, the strip 93 is separated and the terminal 94 is crimped. At this time, the holding unit 62 of the second transport mechanism 60 is on standby until the crimping is finished. Specifically, the electric wire 80 is disposed above the strip-attached terminal 91 in a state where the holding portion 62 that holds the strip-attached terminal 91 is located at the target position P3. Here, the electric wire 80 is disposed in the guide recess 63 b provided on the upper surface of the holding portion 62. At this time, the electric wire 80 is disposed at a position where the core wire exposed portion of the electric wire 80 is crimped by the barrel portion 95. Then, the upper die 72 and the pressing portion 79 attached to the ram member 78 are lowered by lowering the ram member 78. When the pressing portion 79 is lowered, the pressing portion 79 eventually presses the holding portion 62 downward, and the holding portion 62 moves downward with respect to the lower mold 74. As a result, the strip-attached terminal 91 is sheared at the connecting portion between the strip 93 and the terminal 94 and separated into the strip 93 and the terminal 94. Further, when the upper die 72 is lowered, the electric wire 80 and the barrel portion 95 are sandwiched between the upper die 72 and the lower die 74, and the barrel portion 95 is crimped to the electric wire 80.

The above is the operation performed by the terminal conveyance device 40 for one strip-attached terminal 91. By repeating the above operation for a plurality of strip-attached terminals 91, a plurality of terminal-attached electric wires are continuously manufactured.

In addition, the 1st conveyance mechanism 42 concerns on reception of the terminal 91 with a following strip, while the 2nd conveyance mechanism 60 transfers the terminal 91 with a strip to the target position P3, and waits during crimping | compression-bonding. It is good to move the operation. That is, it is good that the 1st conveyance mechanism 42 is performing step S1 and step S2 about the following terminal 91 with a strip between step S5 and step S6. From another viewpoint, while the first transport mechanism 42 is performing steps S1 and S2, the second transport mechanism 60 performs steps S5 and S6 for the previous strip-attached terminal 91. It is good to have.

The first transport mechanism 42 repeats the operations in steps S1 to S4 described above until receiving an end instruction from the control unit 100. That is, the first transport mechanism 42 repeatedly performs the operation of transporting the strip-attached terminal 91 from the starting position P1 to the delivery position P2. In addition, when there are a plurality of starting positions P1, such as when the starting positions P1 are set in the plurality of terminal feed mechanisms 20, in what order the gripping portion 44 is accessed with respect to the plurality of starting positions P1. Is determined according to an instruction from the control unit 100.

The second transport mechanism 60 repeats the operations in steps S3 to S6 described above until receiving an end instruction from the control unit 100. In other words, the second transport mechanism 60 repeatedly performs the operation of receiving the strip-attached terminal 91 at the delivery position P2, transferring the strip-attached terminal 91 to the target position P3, and waiting during crimping.

<Position adjustment>
Next, an operation related to the adjustment of the holding position of the strip-attached terminal 91 will be described with reference to FIGS. FIG. 9 is a diagram illustrating a state in which the grip position adjustment of the strip-attached terminal 91 is performed by the first transport mechanism 42. FIG. 10 is a diagram for explaining how the holding position of the second transport mechanism 60 changes according to the gripping position of the strip-attached terminal 91 by the first transport mechanism 42.

In the terminal transport device 40, as described above, the position of the strip-attached terminal 91 with respect to the holding portion 62 changes by adjusting the position where the grip portion 44 grips the strip 93. Specifically, in the first transport mechanism 42, when the gripping portion 44 grips the strip 93, the gripping position with respect to the strip 93 is adjusted in the x-axis direction so that the second transport mechanism 60 is attached with the strip. When the terminal 91 is delivered, the position of the strip 93 held by the holding unit 62 in the second transport mechanism 60 changes in the y-axis direction.

In carrying out this position adjustment, the gripping claws 46 are effective. That is, if there is no gap in the middle part of the gripping claw, even if the width dimension of the terminal 94 (the dimension along the extending direction of the strip 93) is small, depending on the selected gripping position, There is a risk of interference with the terminal 94. In contrast, here, since the intermediate portion 46 b of the gripping claw 46 is spaced, the intermediate portion 46 b of the gripping claw 46 is positioned close to the terminal 94 along the extending direction of the strip 93. In some cases, even when the position overlapping the terminal 94 when viewed from the gripping direction is gripped, the terminal 94 and the gripping claws 46 are less likely to interfere with each other because the terminal 94 fits in the accommodation space.

More specifically, as shown in FIG. 9, the position of the grip portion 44 is adjusted in the x-axis direction by the grip portion linear movement mechanism 52 at the starting position P1. In FIG. 9, the gripping portion 44 grips the strip 93 at three gripping positions T1, T2, and T3. Of these, at the gripping position T1, the gripping portion 44 is indicated by a solid line, and at the gripping positions T2 and T3, the gripping portion 44 is indicated by a virtual line (two-dot chain line). The gripping position T2 is located on one end side of the strip 93 from the gripping position T1, that is, in the negative x-axis direction in FIG. The gripping position T3 is located on the other end side of the strip 93 from the gripping position T1, that is, in the positive x-axis direction in FIG.

Suppose a case where the strip-attached terminal 91 gripped at the three gripping positions T1, T2, and T3 is transported to the delivery position P2. At this time, since the grip portion 44 is rotated 90 degrees by the grip portion rotating mechanism 54, as shown in FIG. 10, at the delivery position P2, the strip-attached terminal 91 has the strip 93 extending in the y-axis direction. It is handed in the posture along. FIG. 10 shows a state in which the holding unit 62 holds the belt 93 at three holding positions H1, H2, and H3. Among these, at the holding position H1, the strip-attached terminal 91 is indicated by a solid line, and at the holding positions H2 and H3, the strip-attached terminal 91 is indicated by a virtual line (two-dot chain line). The holding position H1 corresponds to the holding position T1, the holding position H2 corresponds to the holding position T2, and the holding position H3 corresponds to the holding position T3.

That is, when the strip-attached terminal 91 is gripped at the gripping position T1, the strip-attached terminal 91 delivered to the second transport mechanism 60 is held by the holding portion 62 at the holding position H1. When the strip-equipped terminal 91 is gripped at the grip position T2 located in the negative x-axis direction in FIG. 9 relative to the grip position T1, the strip-attached terminal 91 transferred to the second transport mechanism 60 is In FIG. 10, the holding portion 62 holds the holding position H2 located in the positive y-axis direction with respect to the holding position H1. Further, when the strip-equipped terminal 91 is gripped at the grip position T3 located in the positive x-axis direction in FIG. 9 relative to the grip position T1, the strip-attached terminal 91 transferred to the second transport mechanism 60 is In FIG. 10, the holding portion 62 holds the holding position H3 located in the negative y-axis direction with respect to the holding position H1.

As described above, when the gripping portion 44 grips the strip-attached terminal 91 at the starting position P1, the holding portion 62 at the delivery position P2 is adjusted by adjusting the gripping position of the gripping portion 44 in the x-axis direction. When holding the strip-attached terminal 91, the position held by the holding portion 62 changes in the y-axis direction. By utilizing this, the holding part 62 can hold the strip-attached terminal 91 at a desired position along the y-axis direction.

Here, the center axis of the crimping portion 95 of the strip-attached terminal 91 held by the second transport mechanism 60 at the target position P3 at the time of crimping and the center axes of the crimping dies 72 and 74 are viewed from the crimping direction. Are required to match. Hereinafter, this operation is referred to as center alignment. When the position of the crimping portion 95 of the strip-attached terminal 91 is different from the holding portion 62 for each type of terminal 94, it is necessary to perform center alignment on the second transport mechanism 60 side, and the second transport mechanism 60 side The control becomes complicated. On the other hand, if the position of the crimping portion 95 of the strip-attached terminal 91 with respect to the holding portion 62 is constant, simple control for moving the holding portion 62 to the target position P3 by a certain distance is sufficient. At this time, as described above, by adjusting the position at which the gripping portion 44 grips the strip 93 on the first transport mechanism 42 side, even if the type of the terminal 94 is different, the holding portion 62 is brought into a predetermined position. It can be delivered so that the barrel portion 95 of the strip-attached terminal 91 is positioned.

More specifically, the desired position can be set, for example, at the central axis of the arc of the guide recess 63b. That is, the position of the holding portion 62 at the target position P3 is set so that the center axis of the arc of the guide recess 63b coincides with the center at the target position P3 during the crimping. Thereby, the holding | maintenance part 62 hold | maintains the strip-attached terminal 91 in the delivery position P2 so that the center axis | shaft of the crimping | compression-bonding part 95 of the terminal 91 with a strip may correspond with the center axis of the circular arc of the guide recessed part 63b seeing from a crimping direction. This makes center alignment possible. Accordingly, when the holding portion 62 holds the strip-attached terminal 91 at the delivery position P2, the central axis of the crimp portion 95 of the strip-attached terminal 91 coincides with the central axis of the arc of the guide recess 63b when viewed from the crimping direction. As described above, when the gripping portion 44 adjusts the gripping position of the strip 93 of the strip-attached terminal 91 at the starting position P1, the centering can be performed without complicated control on the second transport mechanism 60 side.

According to such a terminal transport device 40 and the terminal crimping device 10 in which the terminal transport device 40 is incorporated, the strip-attached terminal 91 is provided so as to be transportable from the starting position P1 to the delivery position P2. A gripping portion having a pair of gripping claws 46 for gripping one portion, and having a gap in the intermediate portion 46b with the tips of the pair of gripping claws 46 gripping the strip 93 of the terminal 91 with the strip 44 and a gripper moving mechanism 50 provided so as to be able to reciprocate the gripper 44 from the starting position P1 to the delivery position P2, a strip is formed on the intermediate portion 46b of the gripping claw 46. An accommodation space capable of accommodating the terminal 94 portion of the auxiliary terminal 91 is formed. As a result, when the terminal 94 portion transports the strip-attached terminal 91 protruding toward the gripping claw 46, the terminal 94 portion is accommodated even when the pair of gripping claws 46 grip the strip 93 from the terminal 94 portion side. By being in the space, the terminal 94 portion and the gripping claw 46 are less likely to interfere with each other.

Further, the gripper moving mechanism 50 further includes a gripper rotation mechanism 54 that rotates the gripper 44, and the second transport mechanism 60 is in a posture in which the strip-attached terminal 91 received at the starting position P 1 is rotated. Since the gripping claw 46 is provided so that the gripping position of the strip 93 can be selected when the gripping claw 46 grips the strip-attached terminal 91 at the starting position P1, the delivery posture changes depending on the gripping position selected by the gripping claw 46. At this time, the central axis of the crimping portion 95 of the terminal 91 with the strip and the central axes of the crimping dies 72 and 74 held in the second transport mechanism 60 at the target position P3 at the time of crimping are viewed from the crimping direction. By selecting the gripping position of the strip 93 so as to match, it becomes difficult to cause a crimping error.

In addition, since the gripper moving mechanism 50 further includes a gripper linear movement mechanism 52 that moves the gripper 44 along the extending direction of the strip 93 of the strip-attached terminal 91 at the starting position P1, the gripper moving mechanism 50 is simplified. The gripping position of the strip 93 can be selected with the configuration. In addition, the second transport mechanism 60 moves the holding unit 62 in a direction intersecting the moving direction of the holding unit 62 that receives and holds the strip-attached terminal 91 from the first transport mechanism 42 and the gripping unit linear movement mechanism 52. Since the holding portion moving mechanism 66 is provided, when the strip-attached terminal 91 is rotated, the delivery posture changes along the moving direction of the holding portion 62 depending on the holding position selected by the holding claw 46.

{Modifications}
Next, a terminal conveyance device 40A according to a modification will be described. FIG. 11 is a plan view schematically showing a configuration of a terminal conveyance device 40A according to a modification. FIG. 12 is a plan view schematically showing an operation example of the terminal conveyance device 40A according to the modification. In the description of this modification, the same components as those described in the embodiment are denoted by the same reference numerals and description thereof is omitted.

As a modification, the terminal conveyance device 40A is provided with a plurality of holding parts 62 (two in this case). Further, a plurality of (here, two) first transport mechanisms 42 are provided.

Specifically, the second transport mechanism 60 A includes two holding units 62 provided so as to be movable by the same holding unit moving mechanism 66. The two holding portions 62 are arranged at intervals along the moving direction, and move simultaneously while maintaining the intervals. More specifically, a holding part 62a that reciprocates between the delivery position P2a and the target position P3 and a holding part 62b that reciprocates between the delivery position P2b and the target position P3 are provided. Here, the dimension between the delivery position P2a and the target position P3, the dimension between the delivery position P2b and the target position P3, and the interval between the two holding

portions

62a and 62b are set to the same dimension. Then, the two holding

portions

62a and 62b move at the same time in a state where the interval is maintained, so that one of the two holding

portions

62a and 62b is located at the delivery position P2 and the other is the target position P3. Located in.

One first transport mechanism 42a of the two first transport mechanisms 42 transports the strip-attached terminal 91 from the starting position P1 to the delivery position P2a, and at the delivery position P2a, attaches the strip-attached terminal 91 to the holding portion 62a. Deliver. The other first transport mechanism 42b of the two first transport mechanisms 42 transports the strip-attached terminal 91 from the starting position P1 to the delivery position P2b, and at the delivery position P2b, the strip-attached terminal is connected to the holding portion 62b. Deliver 91.

According to such a terminal transport apparatus 40A, while one holding part 62 receives the strip-attached terminal 91 from the first transport mechanism 42 at the delivery position P2, the other holding part 62 is positioned at the target position P3. Then, crimping by the crimping mechanism 70 can be performed. Thereby, the efficiency which concerns on manufacture of an electric wire with a terminal is improved.

At this time, the first conveyance mechanism 42 performs the position adjustment described above, whereby the strip-attached terminal 91 is held at a desired position with respect to the holding

portions

62a and 62b. Thus, center adjustment can be performed at the target position P3 without complicated control by the second transport mechanism 60.

{Another variation}
In the embodiment, the terminal transport device 40 has been described as including the first transport mechanism 42 and the second transport mechanism 60, but this is not essential. For example, the terminal conveyance device may include only the first conveyance mechanism 42. In this case, it is conceivable that the terminal 94 is crimped at the delivery position P 2 where the first transport mechanism 42 delivers the strip-attached terminal 91.

Further, although the first transport mechanism 42 has been described as including the gripping portion linear movement mechanism 52 and the gripping portion rotation mechanism 54, this is not essential. For example, the first transport mechanism only needs to include one of the gripper linear movement mechanism 52 and the gripper rotation mechanism 54.

That is, the terminal conveying device 40 only needs to be able to convey the strip-attached terminal 91 from the starting position P1 to another position such as the crimping position of the terminal 94, and the route, movement method, and the like may be appropriately set.

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

Although the present invention has been described in detail as described above, 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.
