[Prior art]
A conventional jumper wire mounting apparatus will be described below with reference to FIGS.
The structure of the conventional jumper wire mounting apparatus 1 is demonstrated. As shown in FIG. 10, the jumper wire mounting device 1 is roughly divided into a jumper wire sending device 21 and a jumper wire insertion device 31.
The jumper wire sending device 21 is a device that supplies the jumper wire 41 to the jumper wire inserting device 31, and includes a jumper wire guide 23, a pair of feed rollers 24, and each pulse motor 25 that drives each feed roller 24. . The jumper wire guide 23 is engaged with a rotation center shaft 27 attached to the frame 26 and is driven by a drive device 28 around the rotation center shaft 27 at a jumper wire delivery position 44 indicated by a solid line and a two-dot chain line. It is a member that swings between the jumper wire cutting position 45 shown, and has a delivery passage 22 for delivering the jumper wire 41. The pair of feed rollers 24 are rollers arranged to face each other with the jumper wire 41 interposed therebetween, and are rotated in opposite directions by the corresponding pulse motors 25 to feed out the jumper wire 41.
In such a configuration, when the jumper wire guide 23 is disposed at the jumper wire delivery position 44, the jumper wire sandwiched between the feed rollers 24 by the rotation of the feed rollers 24 by the respective pulse motors 25. 41 is sent out, and the jumper wire 41 sent out is supplied to the jumper wire insertion device 31 through the passage 22.
[0003]
The jumper wire insertion device 31 forms a movable blade 38 and a fixed blade 37 for cutting the jumper wire 41 supplied from the jumper wire delivery device 21 and the cut jumper wire 41 into a staple shape, and pierces the substrate 42. An insertion tool 33 for inserting the jumper wire 41 formed in the pair of wire insertion holes 43 provided is disposed above the substrate 42. The insertion tool 33 includes a pair of bending dies 34 and a pair of insertion guides 35 for forming the cut jumper wire 41 into a staple shape, and a pair of pushers for pressing the formed jumper wire 41 into the wire insertion hole 43 of the substrate 42. 36.
[0004]
The fixed blade 37, the movable blade 38, the bending die 34, the insertion guide 35, and the pusher 36 are sent from the jumper wire sending device 21 in a state where the jumper wire guide 23 is arranged at the jumper wire cutting position 45. The jumper wire 41 is arranged along the extending direction. Further, the bending die 34, the insertion guide 35, and the pusher 36 are arranged so that the distance between the pair of insertion guides 35 in the extending direction of the jumper wire 41 substantially matches the distance between the pair of wire insertion holes 43. Yes.
Further, the bending die 34 and the pusher 36 are disposed at the same position in the extending direction of the jumper wire 41, and each pusher 36 is disposed inside the insertion guide 35 disposed at the above-described interval and each of the pushers 36. It is arranged adjacent to the insertion guide 35.
[0005]
The operation of the jumper wire insertion device 31 configured as described above will be described below with reference to FIGS.
In the initial state shown in FIG. 11, the insertion guide 35, the pusher 36, and the movable blade 38 are located at the raised position 51, and the bending die 34 is located above the substrate 42 below the raised position 51. Therefore, the insertion tool 33 is in a state of receiving the jumper wire 41. Further, the jumper wire guide 23 is disposed at the jumper wire delivery position 44 with respect to the insertion tool 33 as shown in FIG. In such a state, first, each pulse motor 25 is activated, and a jumper wire 41 having a predetermined length is sent out by each feed roller 24.
[0006]
Next, as shown in FIG. 12, the jumper wire guide 23 is moved to the jumper wire cutting position 45 by the operation of the driving device 28. Due to this movement, the jumper wire 41 that has been sent out is below the movable blade 38, the insertion guide 35, and the pusher 36 that are disposed at the raised position 51, and the fixed blade 37 that is disposed at the bending position 52. , Located above the bending die 34.
[0007]
Next, as shown in FIG. 13, the pusher 36 is lowered from the raised position 51 to the bending position 52 so that the jumper wire 41 is sandwiched between the bending die 34 and the pusher 36.
Next, as shown in FIG. 14, in a state where the jumper wire 41 is sandwiched between the bending die 34 and the pusher 36, the movable blade 38 is moved from the raised position 51 to the cutting completion position 53 beyond the bending position 52. Lower. Therefore, the jumper wire 41 is cut when the movable blade 38 intersects the fixed blade 37.
Since the jumper wire guide 23 is separated from the fixed blade 37 and the movable blade 38, when the jumper wire 41 is cut, the jumper wire 41 protrudes from the jumper wire guide 23 as shown in the figure. ing.
[0008]
Next, as shown in FIG. 15, in order to form the cut jumper wire 41 into the staple shape, each insertion guide 35 is lowered from the raised position 51 to the substrate 42. Thereby, in the extending direction of the jumper wire 41 extending linearly, the jumper wire 41 is bent at almost both ends of the pair of bending dies 34, and is formed into a U-shape, that is, a staple shape. . The jumper wire 41 thus formed in a staple shape is numbered as a jumper wire 41-1.
In the same process as the bending operation, the driving device 28 is operated and the jumper wire guide 23 returns from the jumper wire cutting position 45 to the jumper wire sending position 44.
[0009]
Next, as shown in FIG. 17, the bending die 34 that is in contact with the pusher 36 moves to the retracted position, so that the pusher 36 is lowered from the bending position 52 to the substrate 42, and is molded along with the lowering. The jumper wire 41-1 is inserted into the wire insertion hole 43 of the substrate 42 by the pusher 36.
In the same process as the insertion operation, the jumper wire 41 is sent out by the feed roller 24 in preparation for the next insertion.
Next, the movable blade 38, the insertion guide 35, and the pusher 36 are raised again to the raised position 51, and the bending die 34 is also returned to the original state and returned to the initial state shown in FIG.
Thereafter, the above process is repeated.
[0010]
[Problems to be solved by the invention]
As described above, when the jumper wire 41 is cut, the jumper wire 41 protrudes from the jumper wire guide 23. In such a state, in the conventional jumper wire mounting apparatus 1, the jumper wire guide 4-1 is formed in the step shown in FIG. 15, that is, the jumper wire guide 23 moves to the jumper wire delivery position 44. In this movement, as shown in FIG. 16, the cut surface 41 a of the jumper wire 41-2 protruding from the jumper wire guide 23 moves while rubbing the side surface 38 a of the movable blade 38. Therefore, a force is applied to the protruding jumper wire 41-2 due to this friction, and the jumper wire 41-2 may be bent. Therefore, when forming the staple-like jumper wire 41-1 next, a molding defect may occur, or the jumper wire 41-1 may be poorly inserted into the wire insertion hole 43. The insertion reliability was lowered.
The present invention has been made in order to solve such a problem, and does not cause molding failure of the jumper wire to be inserted into the substrate, and can ensure the reliability of insertion of the molded jumper wire into the substrate.

The jumper wire mounting device 101 is roughly divided into a jumper wire sending device 121, a jumper wire inserting device 131, and a control device 181.
The jumper wire sending device 121 has the same configuration as the conventional jumper wire sending device 21 described above. Therefore, description of the configuration and operation of the jumper wire sending device 121 is omitted here. However, the operation of each pulse motor 25 as a driving device for each feed roller 24 is controlled by the control device 181, and the operation of the driving device 28 is also controlled by the control device 181. The jumper wire delivery position 44 and the jumper wire cutting position 45 indicate the placement position in the jumper wire guide 23. For convenience, the jumper wire 41 is placed in a state where the jumper wire guide 23 is placed at the jumper wire delivery position 44. The jumper wire sending position 44 also means the position where the jumper wire 41 is disposed. Similarly, the position where the jumper wire 41 is disposed in a state where the jumper wire guide 23 is disposed at the jumper wire cutting position 45 is also defined as the jumper. The wire cutting position 45 shall mean.
[0017]
The jumper wire insertion device 131 has a configuration similar to the configuration of the conventional jumper wire insertion device 31 described above, and a pair of bending dies 34 and a pair of bending dies arranged in a row along the X direction. It has an insertion guide 35, a pair of pushers 36, and a fixed blade 37. The pair of bending dies 34, the pair of insertion guides 35, and the pair of pushers 36 constitute the above-described insertion tool 33. These configurations and operations are the same as those of the above-described conventional jumper wire insertion device 31, and the description thereof is omitted here.
On the other hand, the jumper wire insertion device 131 in the present embodiment includes a movable blade 138 and a cutting drive device 174 that drives the movable blade 138, which are characteristic components of the jumper wire insertion device 131. The jumper wire insertion device 131 includes a bending die driving device 171 for driving the bending die 34, an insertion guide driving device 172 for driving the insertion guide 35, and a pusher driving device 173 for driving the pusher 36. Prepare. The operation of the bending die driving device 171, the insertion guide driving device 172, the pusher driving device 173, and the cutting driving device 174 is controlled by the control device 181.
[0018]
In the jumper wire delivery device 121 and the movable blade 138, or in the jumper wire delivery device 121, the movable blade 138, the fixed blade 37, the cutting drive device 174, and the control device 181. A jumper wire cutting device 161 is configured.
[0019]
The movable blade 138 will be described in detail. For example, as shown in FIGS. 1 and 7, the movable blade 138 is provided with a contact prevention groove 162. The contact preventing groove 162 is formed on the contact surface 138 a of the movable blade 138 that slides while contacting the fixed blade 37 in the movable blade 138 that moves in the thickness direction of the substrate 42, that is, the Z direction by the cutting drive device 174. It is a groove formed in a concave shape along the Y direction orthogonal to the direction, and is formed with an appropriate width in the Z direction from an appropriate distance in the Z direction from the tip 138b which is the blade portion of the movable blade 138. Has been. When the jumper wire 41-2 moves to the jumper wire sending position 44 again after the jumper wire 41 is cut, the contact prevention groove 162 formed in this way is connected to the cut surface 41a of the moving jumper wire 41-2. This prevents the moving jumper wire 41-2 from being deformed.
That is, the movable blade 138 is driven by the cutting drive device 174 whose operation is controlled by the control device 181, moves in the Z direction, cuts the jumper wire 41 with the fixed blade 37, and then after cutting. The cut surface 41a of the cut jumper wire 41 stops at the cutting completion position 153 where the cutting face 41a faces the contact prevention groove 162. Therefore, after cutting, the cutting surface 41 a is not in contact with the movable blade 183 as shown in FIG. 7 with respect to the movable blade 138 positioned at the cutting completion position 153. In this state, even if the jumper wire 41-2 protruding from the jumper wire guide 23 moves as shown by an arrow 163 in FIG. 7 as the jumper wire guide 23 moves to the jumper wire delivery position 44. The force enough to deform the jumper wire 41-2 does not act on the jumper wire 41-2. Therefore, the jumper wire 41-2 is not deformed.
[0020]
In the present embodiment, the contact prevention groove 162 has a rectangular cross-section at the cut surface along the Z direction, as shown in the drawing, but is not limited to this shape. Alternatively, it may be a concave shape such as a U shape. In short, any shape that can execute the above-described function is acceptable. In this embodiment, the depth of the contact prevention groove 162 is constant over the entire length of the groove. For example, the jumper wire 41-2 moves in the direction of the arrow 163 so that the cut surface 41a has an arc shape. Since the locus is drawn, the depth may be changed so that the distance between the cut surface 41a and the bottom surface of the contact prevention groove 162 is constant.
[0021]
In addition, the substrate 42 can be moved in the X and Y directions by a driving device (not shown) so that the wire insertion hole 43 is disposed at a predetermined position below the jumper wire insertion device 131. The movement operation of the substrate 42 is also controlled by the control device 181.
[0022]
The operation of the jumper wire mounting device 101 of the present embodiment configured as described above will be described below including the cutting operation by the jumper wire cutting device 161. The operation control is performed by the control device 181.
FIG. 1 shows an initial state. 2 and FIG. 9 (indicated by “S” in the figure) 1, the insertion tool 33 and the movable blade 138 are arranged at the raised position 51 by the operations of the driving devices 171 to 174. And is in a state of accepting the jumper wire 41. Further, the jumper wire guide 23 is located in the state of facing the insertion tool 33 as shown in FIG. Then, each pulse motor 25 is operated by the operation control of the control device 181, each feed roller 24 rotates, and the jumper wire 41 is sent out by the length required for the jumper.
[0023]
In the next step 2, as shown in FIG. 3, the drive device 28 is operated by the operation control of the control device 181, and the jumper wire guide 23 swings from the jumper wire sending position 44 to the jumper wire cutting position 45. Therefore, the jumper wire 41 delivered from the jumper wire guide 23 is disposed along the X direction below the movable blade 138, the insertion guide 35, and the pusher 36, and above the fixed blade 37 and the bending die 34. The
[0024]
In the next step 3, as shown in FIG. 4, the pusher drive device 173 is operated by the operation control of the control device 181, and the pusher 36 is lowered to the bending position 52 until it comes into contact with the bending die 34. When the pusher 36 is lowered to the bending position 52, the jumper wire 41 is sandwiched between the pusher 36 and the bending die 34. As shown in the drawing, the jumper wire 41 to be clamped is slidable in the extending direction at the tip of the pusher 36 that contacts the bending die 34 and cannot move in the direction orthogonal to the extending direction. V-shaped notches are provided.
[0025]
In the next step 4, as shown in FIG. 5, when the cutting drive device 174 is operated by the operation control of the control device 181, the movable blade 138 is lowered, and the tip 138 b of the movable blade 138 intersects the fixed blade 37. Thus, the jumper wire 41 is cut. Further, as described above, the movable blade 138 is located at the position where the cutting surface 41a of the jumper wire 41 faces the contact prevention groove 162 by the operation of the cutting driving device 174 by the operation control of the control device 181. At 153, the descent is finished. Therefore, in a state where the movable blade 138 has stopped descending, the cut surface 41a is not in contact with the contact surface 138a of the movable blade 138, that is, the movable blade 138.
[0026]
In the next step 5, as shown in FIG. 6, the insertion guide driving device 172 is operated by the operation control of the control device 181, and both the insertion guides 35 are lowered from the raised position 51 to the substrate 42. At this time, the jumper wire 41 sandwiched between the pusher 36 and the bending die 34 is bent by the insertion guide 35 when the insertion guide 35 passes by the side of the bending die 34, is formed into the above-mentioned staple shape, and the jumper wire 41-1.
In step 5, in the present embodiment, the drive device 28 is operated by the operation control of the control device 181 at the same time or almost simultaneously with the lowering operation of the insertion guide 35, and the jumper wire guide 23 is moved from the jumper wire cutting position 45. Move to jumper wire delivery position 44. As the jumper wire guide 23 moves, the moving jumper wire 41-2 protruding from the jumper wire guide 23 moves in the direction of arrow 163 as shown in FIG. At this time, the movable blade 138 remains stopped at the cutting completion position 153. Therefore, as described above, the cut surface 41a of the jumper wire 41-2 is opposed to the contact prevention groove 162 and is not in contact with the contact surface 138a of the movable blade 138. Such a force that causes deformation does not act on the jumper wire 41-2. Therefore, the jumper wire 41-2 is not deformed by the above movement.
[0027]
In the next step 6, as shown in FIG. 8, the bending die driving device 171 and the pusher driving device 173 are operated by the operation control of the control device 181 so that the bending die 34 is moved to the retracted position and the pusher 36 is moved. It descends from the bending position 52 to the substrate 42. As the pusher 36 is lowered, the molded jumper wire 41-1 is inserted into the pair of wire insertion holes 43 while being guided by the insertion guide 35.
In the step 6, in the present embodiment, the pulse motor 24 is operated by the operation control of the control device 181 at the same time or almost simultaneously with the lowering operation of the pusher 36, and the double feed roller 24 is rotated. The jumper wire 41 is sent out in preparation for the insertion operation.
[0028]
In the next step 7, it is further determined whether or not to continue the operation of inserting the jumper wire 41-1. When continuing, it returns to the said step 1, and as shown in FIG. 2, the movable blade 138, the pusher 36, and the insertion guide 35 raise to the raising position 51, the bending die 34 returns to the bending position 52, and returns to the said initial state. . Then, Step 2 to Step 7 are executed again.
On the other hand, when not continuing, the operation is terminated.
[0029]
A second embodiment;
In step 5, when the jumper wire 41-2 moves in the direction of the arrow 163 shown in FIG. 7, the jumper wire 41-2 is not deformed. Therefore, in the first embodiment described above, the contact prevention groove 162 is formed in the movable blade 138. In addition, by controlling the operation of the control device 181, after the jumper wire 41 is cut, the lowering of the movable blade 138 is stopped at a position where the cut surface 41 a of the jumper wire 41 and the contact prevention groove 162 face each other. did.
However, the means for preventing the jumper wire 41-2 from being deformed when the jumper wire 41-2 moves in the direction of the arrow 163 shown in FIG. 7 is not limited to this, and the operation control of the control device 181 is not limited thereto. Thus, for example, the following deformation prevention operation may be performed by at least one of the jumper wire feeding device 121 and the cutting drive device 174, thereby obtaining the same effect as the first embodiment. it can. In the second embodiment described below, the movable blade 138 is not provided with the contact prevention groove 162. Other configurations are the same as those of the first embodiment.
[0030]
After the jumper wire 41 is cut in the step 4, each pulse motor 25 is operated by the operation control of the control device 181 so that the cut surface 41a and the contact surface 138a of the movable blade 138 are not in contact with each other. 41-2 is pulled into the jumper wire guide 23 side. By doing so, even when the jumper wire 41-2 moves in the direction of the arrow 163 shown in FIG. 7 in the step 5, the cut surface 41a does not contact the movable blade 138, and the jumper wire 41-2 There is no deformation.
[0031]
Further, as another method, after the jumper wire 41 is cut in the step 4, the cutting drive device 174 is operated by the operation control of the control device 181, so that the cutting surface 41 a and the contact surface 138 a of the movable blade 138 are The movable blade 138 is slightly moved along the X direction to the insertion guide 35 side so as not to contact. By doing so, even when the jumper wire 41-2 moves in the direction of the arrow 163 shown in FIG. 7 in the step 5, the cut surface 41a does not contact the movable blade 138, and the jumper wire 41-2 There is no deformation.
[0032]
In each of the above-described embodiments, the jumper wire 41 is cut by moving the movable blade 138 relative to the fixed blade 37. However, the present invention is not limited to this, and both blades are moved relatively. Just do it.
[0033]
【The invention's effect】
As described in detail above, according to the jumper wire cutting device of the first aspect and the jumper wire mounting device of the third aspect of the present invention, the jumper wire is cut after the jumper wire is cut by providing the movable blade with the contact prevention groove. When the wire moves, there is no contact between the cut surface of the jumper wire and the movable blade. Therefore, when the jumper wire moves, a force that causes deformation does not act on the jumper wire. Therefore, the moving jumper wire is not deformed. Therefore, the molding failure of the jumper wire to be inserted into the substrate does not occur, and the reliability of insertion of the molded jumper wire into the substrate can be increased as compared with the conventional case.
