As shown in FIG. 8, first, the electric wire 10 with a terminal is gripped by the moving clamp 42 (step S1), and then the electric wire 10 with a terminal is moved to a position in front of the connector 20 by the moving clamp 42 (step S2). Next, the electric wire 10 with a terminal is inserted into the connector 20 by the moving clamp 42 (step S3). The details of each step will be described below.

FIG. 9 is a flowchart showing the details of the step (step S1) of gripping the electric wire 10 with terminals.

Specifically, as shown in FIG. 1, the operator moves the electric wire 11 forward while pinching the electric wire 11, and the terminal 12 provided at the tip of the electric wire 11 is moved to the first straightening wall 31A and the second straightening wall 31A of the terminal posture straightening tool 30. Press against the straightening wall 32A.

As shown in FIG. 10, here, the terminal 12 has a rectangular cross section. The gap between the first straightening wall 31A and the second straightening wall 32A becomes narrower toward the front. Therefore, even if the terminal 12 is tilted to the left or right from the electric wire 11, the terminal 12 is sandwiched between the first straightening wall 31A and the second straightening wall 32A, so that the terminal 12 is straightened in the front-rear direction. NS. Further, the terminal 12 is sandwiched between the first straightening wall 31A and the second straightening wall 32A, so that the terminal 12 is straightened to a posture along the first straightening wall 31A and the second straightening wall 32A.

Therefore, even if the terminal 12 is tilted around the center line of the electric wire 11, the terminal 12 is corrected to a straight posture in the vertical direction. The surface 33A of the base 33 is horizontal. Therefore, the posture of the terminal 12 can also be corrected by placing the terminal 12 on the surface 33A of the base 33.

As described above, the energization detection circuit 39 is connected to the first electrode 31 having the first straightening wall 31A and the second electrode 32 having the second straightening wall 32A (see FIG. 3). Therefore, when the operator presses the terminal 12 of the electric wire 10 with a terminal against the first straightening wall 31A and the second straightening wall 32A, the posture of the terminal 12 is corrected as described above, and at the same time, the current is applied to the energization detection circuit 39. Flows. As a result, the signal P1 is sent from the energization sensor 38 that has detected the energization to the control device 100 (see FIG. 5). The control device 100 has a continuity determination unit 105 that determines whether or not the first electrode 31 and the second electrode 32 are electrically connected (see FIG. 7). The continuity determination unit 105 determines the continuity between the first electrode 31 and the second electrode 32 based on the signal P1 from the energization sensor 38 (step S12). As a result, when it is determined that the conduction is conducted, the control device 100 drives the actuator 71 and closes the positioning clamp 41 (step S13). As a result, the electric wire 11 is gripped by the positioning clamp 41.

Next, the control device 100 lowers the moving clamp 42 by driving the third drive mechanism 45C, and closes the moving clamp 42 by driving the actuator 72 (step S14). As a result, the electric wire 11 is gripped by the moving clamp 42.

After the moving clamp 42 grips the electric wire 11, the control device 100 drives the actuator 71 to open the positioning clamp 41 (step S15). As a result, the gripping of the electric wire 11 by the positioning clamp 41 is released while the moving clamp 42 holds the electric wire 11. The above is the details of step S1 for gripping the electric wire 10 with terminals.

Next, with reference to FIG. 11, the details of the step (step S2) of moving the electric wire 10 with a terminal to the position in front of the connector 20 will be described. As described above, the position of the moving clamp 42 is detected by the clamp position sensor 50 (see FIG. 5). The control device 100 controls the movement of the moving clamp 42 based on the position detected by the clamp position sensor 50. The control device 100 receives the signal P2 from the clamp position sensor 50 and controls the drive device 45. Here, the position of the moving clamp 42 before moving is referred to as a first position. The first position is the position where the moving clamp 42 starts to grip the electric wire 11. First, the first movement control unit 101 of the control device 100 drives the first drive mechanism 45A to move the movement clamp 42 upward (first movement direction) from the first position (step S21). Then, the terminal 12 crimped to the tip of the electric wire 11 passes through the first passage sensor 51, and the passage is detected (step S22).

By the way, the moving clamp 42 does not grip the terminal 12, but grips the electric wire 11 to which the terminal 12 is crimped. Therefore, for example, as shown in an exaggerated manner in FIG. 12, when the electric wire 11 is bent in the vertical direction, the terminal 12 and the moving clamp 42 are displaced in the vertical direction. In the present embodiment, since the first pass sensor 51 is installed at a predetermined position, the position when the terminal 12 passes through the first pass sensor 51 is specified in advance. Assuming that the vertical positions of the terminal 12 and the moving clamp 42 when the first passing sensor 51 detects the passage of the terminal 12 are V12 and V42, respectively, the vertical displacement amount ΔV of the moving clamp 42 with respect to the terminal 12 is It can be calculated by ΔV = V42-V12. When the first pass sensor 51 detects the passage of the terminal 12, the first position shift detection unit 111 of the control device 100 calculates the vertical position shift amount ΔV of the moving clamp 42 with respect to the terminal 12 as described above. (Step S23).

The moving clamp 42 is set to move upward to a predetermined second position. The first movement control unit 101 of the control device 100 determines whether or not the movement clamp 42 has risen to the second position based on the position detected by the clamp position sensor 50 (step S24). When the first movement control unit 101 of the control device 100 determines that the movement clamp 42 has risen to the second position, the first drive mechanism 45A is stopped. Then, the second movement control unit 102 of the control device 100 drives the second drive mechanism 45B. As a result, the movement clamp 42 stops the upward movement, changes the movement direction, and moves to the left (second movement direction) (step S25).

When the moving clamp 42 moves to the left, the terminal 12 passes through the second passing sensor 52, and the passing is detected (step S26). For example, as shown in an exaggerated manner in FIG. 13, when the electric wire 11 is bent in the left-right direction, the movement clamp 42 and the terminal 12 are displaced in the left-right direction. In the present embodiment, since the second pass sensor 52 is installed at a predetermined position, the position when the terminal 12 passes through the second pass sensor 52 is specified in advance. Assuming that the positions of the terminal 12 and the moving clamp 42 in the left-right direction when the second passing sensor 52 detects the passage of the terminal 12 are H12 and H42, respectively, the amount of left-right misalignment ΔH of the moving clamp 42 with respect to the terminal 12 is It can be calculated by ΔH = H42-H12. When the second passage sensor 52 detects the passage of the terminal 12, the second displacement detection unit 112 of the control device 100 calculates the lateral displacement amount ΔH of the moving clamp 42 with respect to the terminal 12 as described above. (Step S27).

The movement clamp 42 is set to move to the left to a predetermined third position. The third position is a position in front of the connector 20. The second movement control unit 102 of the control device 100 determines whether or not the movement clamp 42 has reached the third position based on the position detected by the clamp position sensor 50 (step S28). The second movement control unit 102 of the control device 100 stops the second drive mechanism 45B when it determines that the movement clamp 42 has reached the third position. As a result, the leftward movement of the movement clamp 42 is stopped (step S29). The above is the details of step S2 for moving the electric wire 10 with a terminal to a position in front of the connector 20.

Next, the details of the step (step S3) of inserting the electric wire 10 with a terminal into the connector 20 will be described with reference to FIG. In the above-mentioned third position, the moving clamp 42 is the terminal hole 21 of the connector 20 (specifically, of the plurality of terminal holes 21, the terminal 12 of the electric wire 10 with a terminal held by the moving clamp 42 is to be inserted. It is a position directly facing the hole 21). In other words, the third position is a position where the terminal 12 is inserted into the terminal hole 21 when the moving clamp 42 moves forward as it is, assuming that the electric wire 11 is not bent. The correction unit 108 of the control device 100 corrects the position of the moving clamp 42 in step S31. Specifically, the correction unit 108 of the control device 100 sets a position deviated by ΔV to the lower side and ΔH to the right side from the third position as the corrected position (hereinafter referred to as the fourth position). If ΔV is a positive value, the position is shifted downward, and if ΔV is a negative value, the position is shifted upward. If ΔH is a positive value, the position is shifted to the right, and if ΔH is a negative value, the position is shifted to the left. Then, the correction unit 108 of the control device 100 controls the first drive mechanism 45A and the second drive mechanism 45B, and moves the movement clamp 42 to the corrected fourth position.

The movement to the third position and the movement to the fourth position may be continuous in time. That is, the moving clamp 42 may move to the fourth position without stopping at the third position. Further, here, the control device 100 decides to move the movement clamp 42 to the third position and then to the fourth position, but it may be moved to the fourth position without moving to the third position. .. That is, the control device 100 corrects the position while the moving clamp 42 is moving from the second position to the third position, and moves the moving clamp 42 directly from the second position to the fourth position. You may.

By correcting the position in step S31, the terminal 12 is positioned at a position suitable for the terminal hole 21. After that, the insertion control unit 120 of the control device 100 controls the first drive mechanism 45A to move the movement clamp 42 forward. As a result, the terminal 12 is inserted into the terminal hole 21. The above is the details of the step of inserting the electric wire 10 with a terminal into the connector 20.

After that, the control device 100 drives the actuator 72 to open the moving clamp 42. As a result, the grip of the electric wire by the moving clamp 42 is released. Then, the control device 100 drives the first to third drive mechanisms 45A to 45C to move the movement clamp 42 to the initial position (position shown in FIG. 1).

The above steps S1 to S3 are repeated as many times as the number of electric wires 10 with terminals attached to the connector 20. By repeating the above steps S1 to S3, a plurality of electric wires with terminals 10 can be attached to the connector 20, and a wire harness in which a plurality of electric wires with terminals 10 are combined can be manufactured.

According to the method for manufacturing a wire harness according to the present embodiment, the posture of the terminal 12 is corrected by using the terminal posture corrector 30 before the terminal 12 is inserted into the terminal hole 21 of the connector 20, so that it is cheaper than the conventional method. And easily, the terminal 12 can be satisfactorily inserted into the terminal hole 21 of the connector 20. Therefore, a good wire harness can be manufactured cheaper and easier than before.

In the above description, the case where the so-called female terminal 12 is crimped to the electric wire 11 of the electric wire 10 with a terminal has been described. However, there are various forms of the terminal 12. For example, as shown in FIG. 15, a so-called male terminal 12 may be crimped to the electric wire 11. The male terminal 12 has a root portion 12a and a tip portion 12b whose left-right width and vertical width are smaller than those of the root portion 12a. The tip portion 12b is formed in a pin shape.

The terminal posture straightening tool 30 has a first straightening wall 31A and a second straightening wall 32A, but as shown in FIG. 16, the front side of the first straightening wall 31A and the second straightening wall 32A is open. Although the first insulating member 35 and the second insulating member 36 are arranged on the front side of the first straightening wall 31A and the second straightening wall 32A, the first extension surface 35A and the second insulating member 36 of the first insulating member 35 are arranged. A gap is formed between the second extension surface 36A and the second extension surface 36A. Therefore, when the male terminal 12 is pushed between the first electrode 31 and the second electrode 32, the tip portion 12b of the terminal 12 enters the gap between the first extension surface 35A and the second extension surface 36A. .. The tip portion 12b does not get in the way, and the root portion 12a can be pressed against the first straightening wall 31A and the second straightening wall 32A. Therefore, even the male terminal 12 can correct the posture.

By the way, when the terminal 12 is inserted between the first electrode 31 and the second electrode 32, the terminal 12 may be inserted with a slight inclination to the left or right side. For example, when the terminal 12 is inserted with a slight inclination to the right, the root portion 12a is pressed against the first straightening wall 31A and the second straightening wall 32A before the root portion 12a of the terminal 12 is pressed against the first straightening wall 31A. At the same time, the tip portion 12b may come into contact with the second extension surface 36A of the second insulating member 36. Assuming that a part of the second electrode 32 is extended instead of the second insulating member 36, the posture of the terminal 12 is formed by pressing the root portion 12a against the first straightening wall 31A and the second straightening wall 32A. The first electrode 31 and the second electrode 32 become conductive before the correction is made. In this case, the positioning clamp 41 is closed before the posture of the terminal 12 is corrected (see step S13), and the posture of the terminal 12 cannot be corrected. However, in the terminal posture corrector 30 according to the present embodiment, since the first extension surface 35A and the second extension surface 36A are formed of an insulating member, even if the tip portion 12b of the terminal 12 comes into contact, the root portion 12a The first electrode 31 and the second electrode 32 do not conduct with each other until is pressed against the first straightening wall 31A and the second straightening wall 32A. Therefore, even when the terminal 12 is inserted with a slight inclination to the left or right side, the posture of the terminal 12 can be corrected.

Next, various effects produced by the present embodiment will be described.

According to the terminal posture straightening tool 30 according to the present embodiment, as shown in FIG. 3, the first straightening wall 31A and the second straightening wall 32A are inclined so as to approach each other toward the first direction F1. The first straightening wall 31A and the second straightening wall 32A are formed in a so-called tapered shape. Therefore, as shown in FIG. 10, when the electric wire 10 with a terminal is moved in the first direction F1 and the terminal 12 is pressed against the first straightening wall 31A and the second straightening wall 32A, the terminal 12 becomes the first straightening wall 31A. It will be sandwiched between the second straightening wall 32A. Here, the first straightening wall 31A and the second straightening wall 32A extend straight toward the third direction F3. Therefore, even if the posture of the terminal 12 is tilted, when the terminal 12 is sandwiched between the first straightening wall 31A and the second straightening wall 32A, the terminal 12 is corrected to the posture along the straightening walls 31A and 32A. NS. That is, the posture of the terminal 12 is corrected to the posture along the third direction F3. Therefore, according to the terminal posture corrector 30, the posture of the terminal 12 can be corrected easily and inexpensively.

In the present embodiment, the first straightening wall 31A and the second straightening wall 32A need only be surfaces that extend straight toward the third direction F3, and are not necessarily in plan view (in other words, along the third direction F3). It does not have to be a straight surface (when viewed). For example, as shown in FIG. 17, the first straightening wall 31A and the second straightening wall 32A may be formed of a curved curved surface in a plan view.

However, here, the first straightening wall 31A and the second straightening wall 32A are formed of a flat surface (see FIG. 3). Therefore, when the terminal 12 is pressed against the first straightening wall 31A and the second straightening wall 32A, the terminal 12 can be smoothly moved in the first direction F1 along the first straightening wall 31A and the second straightening wall 32A. can. Therefore, the posture correction process of the terminal 12 can be smoothly performed.

In the present embodiment, the first electrode 31 and the second electrode 32 are placed on the table 33. The base 33 has a horizontal surface 33A located between the first straightening wall 31A and the second straightening wall 32A. However, the platform 33 is not always necessary, and the horizontal surface 33A may not be necessary. However, according to the present embodiment, since the horizontal surface 33A is provided below the first straightening wall 31A and the second straightening wall 32A, the terminal 12 can be placed on the surface 33A to form the terminal 12. Up and down positioning can be performed. Further, by placing the terminal 12 on the surface 33A and sliding it forward, the terminal 12 can be easily pressed against the first straightening wall 31A and the second straightening wall 32A.

According to the present embodiment, the first extension surface 35A extending forward from the first straightening wall 31A and the second extension surface 36A extending forward from the second straightening wall 32A are provided, and the first extension surface 35A and the second extension surface are provided. A gap is formed between the surface 36A and the surface 36A. Therefore, the posture can be corrected for both the female terminal 12 (see FIG. 10) and the male terminal 12 (see FIG. 16).

According to the present embodiment, the first straightening wall 31A is formed on the first electrode 31, and the second straightening wall 32A is formed on the second electrode 32. Therefore, when the terminal 12 is pressed against the first straightening wall 31A and the second straightening wall 32A, the first electrode 31 and the second electrode 32 become conductive via the terminal 12. That is, when the posture of the terminal 12 is corrected, the first electrode 31 and the second electrode 32 become conductive. Therefore, the completion of the posture correction of the terminal 12 can be detected based on the presence or absence of continuity of the first electrode 31 and the second electrode 32.

As described above, in the case of the male terminal 12 (see FIG. 16), for example, when the terminal 12 is inserted with a slight inclination to the right, the root portion 12a comes into contact with the first straightening wall 31A and at the same time, the tip portion 12b is extended to the second. May come into contact with surface 36A. However, since the second extension surface 36A is formed on the second insulating member 36, the first electrode 31 and the second electrode 32 before the root portion 12a is pressed against the first straightening wall 31A and the second straightening wall 32A. And do not conduct. Therefore, the completion of posture correction can be detected for both the female terminal 12 and the male terminal 12 based on the presence or absence of continuity of the first electrode 31 and the second electrode 32.

According to the present embodiment, as shown in FIG. 4, a first inclined surface 35B is provided on the upper side of the first extension surface 35A, and a second inclined surface 36B is provided on the upper side of the second extension surface 36A. There is. A gap is formed between the first inclined surface 35B and the second inclined surface 36B so that the distance becomes wider toward the upper side. Therefore, after correcting the posture of the male terminal 12, the tip portion 12b of the terminal 12 can be smoothly moved upward.

According to the terminal insertion device 2 according to the present embodiment, when the energization sensor 38 detects that the first electrode 31 and the second electrode 32 are conducting, the moving clamp 42 is made to grip the electric wire 11 and the drive device. The moving clamp 42 is moved by 45. In this way, after the posture correction of the terminal 12 is completed, the movement of the terminal-attached electric wire 10 from the terminal posture correction tool 30 can be automatically started.

The drive device 45 moves the moving clamp 42 so that the terminal 12 of the electric wire 10 with a terminal gripped by the moving clamp 42 is inserted into the terminal hole 21 of the connector 20. Therefore, the process from correcting the posture of the terminal 12 to inserting it into the terminal hole 21 of the connector 20 can be automatically performed. The operation of inserting the terminal 12 into the terminal hole 21 is automatically performed by the drive device 45, but since the posture of the terminal 12 is corrected by the terminal posture corrector 30, the terminal 12 is satisfactorily inserted into the terminal hole 21. be able to.

Further, according to the present embodiment, since the first straightening wall 31A and the second straightening wall 32A are formed in a tapered shape, the electric wire 10 with a terminal is moved in the first direction F1 to move the terminal 12 to the first straightening wall. When pressed against 31A and the second straightening wall 32A, the position of the terminal 12 in the first direction F1 is uniquely determined. That is, since the shapes and dimensions (taper angle, etc.) of the first straightening wall 31A and the second straightening wall 32A are known, and the shape and dimensions of the terminal 12 are also known, the terminal 12 is the first straightening wall 31A and the second straightening wall 31A. The position of the terminal 12 in the first direction F1 when sandwiched between the straightening walls 32A can be uniquely calculated in advance. Therefore, according to the present embodiment, the posture of the terminal 12 can be corrected and the terminal 12 can be positioned in the first direction F1. Since the position of the terminal 12 in the first direction F1 is determined, the amount of movement of the movement clamp 42 in the first direction F1 when the terminal 12 is inserted into the terminal hole 21 of the connector 20 can be determined in advance. Further, according to the present embodiment, since the terminal 12 is sandwiched between the straightening walls 31A and 32A at a position intermediate between the first straightening wall 31A and the second straightening wall 32A, the positioning of the terminal 12 in the second direction F2 is also possible. It can be carried out.

In the description of the embodiment, the cross-sectional shape of the terminal 12 is a quadrangle, but the cross-sectional shape of the terminal 12 is not limited to a quadrangle. The cross-sectional shape of the terminal 12 is preferably polygonal, but the terminal 12 having a cross-sectional shape other than the polygonal shape can also be used. For example, the terminal posture corrector 30 and the terminal insertion device 2 according to the embodiment can also be used for the terminal 12 having a circular cross-sectional shape.

The embodiment is merely an example, and the present invention is not limited to the embodiment. Various other embodiments are possible.

As schematically shown in FIG. 18A, in the above-described embodiment, the surfaces of the first straightening wall 31A and the second straightening wall 32A are planes extending straight toward the third direction F3. However, the shapes of the first straightening wall 31A and the second straightening wall 32A can be arbitrarily changed according to the shape of the terminal 12.

For example, as shown in FIG. 18B, the first straightening wall 31A has a surface 31A1 that goes in the direction opposite to the second direction F2 toward the third direction F3 and a second direction toward the third direction F3. It may be composed of a surface 31A2 facing F2. Even if the second straightening wall 32A is composed of a surface 32A1 that faces the second direction F2 toward the third direction F3 and a surface 32A2 that faces the direction opposite to the second direction F2 toward the third direction F3. good. As a result, the first straightening wall 31A and the second straightening wall 32A have a shape suitable for the terminal 12 having a hexagonal cross section, and the terminal 12 having a hexagonal cross section is subjected to good posture correction. Can be done. Further, the first straightening wall 31A may have other surfaces in addition to the surfaces 31A1 and 31A2, and the second straightening wall 32A may have other surfaces in addition to the surfaces 32A1 and 32A2. As a result, the first straightening wall 31A and the second straightening wall 32A have a shape suitable for terminals having a polygonal cross section other than a hexagon, and good posture correction can be performed on such terminals. can.

Further, as shown in FIG. 18C, the first straightening wall 31A and the second straightening wall 32A may be formed of a curved surface. As a result, the first straightening wall 31A and the second straightening wall 32A have a shape suitable for the terminal 12 having a circular or elliptical cross section, and good posture correction can be performed on such a terminal. can.

In the embodiment as shown in FIGS. 18 (b) and 18 (c), after the terminal 12 is pressed against the first straightening wall 31A and the second straightening wall 32A, the terminal 12 can be moved upward as it is. Can not. Therefore, after the terminal 12 is pressed against the first straightening wall 31A and the second straightening wall 32A to correct the posture, the terminal 12 is moved slightly backward by pulling the electric wire 11 backward, and then the electric wire 11 and the terminal. It is advisable to move 12 upwards.

As shown in FIG. 4, in the above-described embodiment, the first extension surface 35A and the second extension surface 36A are flat surfaces, and the first inclined surface 35B and the second inclined surface 36B are flat surfaces. However, the shape of those surfaces is not particularly limited. For example, as shown in FIGS. 19A and 19B, even if the first extension surface 35A and the second extension surface 36A are formed of a flat surface and the first inclined surface 35B and the second inclined surface 36B are formed of a curved surface. good. In the embodiment shown in FIG. 19A, the first inclined surface 35B and the second inclined surface 36B are formed of a concave curved surface. In the embodiment shown in FIG. 19B, the first inclined surface 35B and the second inclined surface 36B are formed of a protruding curved surface.

In the above embodiment, the first inclined surface 35B is provided above the first extension surface 35A and the second inclined surface 36B is provided above the second extension surface 36A, but the first inclined surface 35B and the second inclined surface 35B are provided. The inclined surface 36B may not be provided. Further, as shown in FIGS. 20A and 20B, the first extension surface 35A and the second extension surface 36A are inclined from the third direction F3, and the first inclined surface 35B and the second inclined surface 36B are omitted. You may be. In the embodiment shown in FIG. 20A, the first extension surface 35A and the second extension surface 36A are formed of a plane inclined from the third direction F3. In the embodiment shown in FIG. 20B, the first extension surface 35A and the second extension surface 36A are curved surfaces inclined from the third direction F3.

The first straightening wall 31A and the second straightening wall 32A may be arranged on both sides of the terminal 12, and may not necessarily be arranged on the left and right. The first straightening wall 31A and the second straightening wall 32A may be arranged one above the other, for example.

When the male terminal 12 is not used, the first extension surface 35A and the second extension surface 36A may be omitted.

When it is not necessary to detect the completion of the posture correction of the terminal 12, an insulating member having the first correction wall 31A and the second correction wall 32A may be provided instead of the first electrode 31 and the second electrode 32.
