[Problems to be solved by the invention]
However, in the above-described configuration of the conventional example, when the insertion direction is the X direction, the insertion guide 120 of the jumper wire insertion unit 103 is not in an accepted state until the insertion operation of the jumper wire insertion unit 103 is completed. The jumper wire 104 cannot be sent out from the supply unit 101. Accordingly, during the insertion cycle time, the jumper wire 104 sending operation of the jumper wire supply unit 101 shown in step # 102 of FIG. 5 and FIG. 6B is performed by the jumper wire insertion shown in steps # 103 to # 109a of FIG. In addition to the insertion operation time of the jumper wire insertion unit 103, the insertion cycle time is increased by the sending time of the jumper wire 104 of the jumper wire supply unit 101, which hinders productivity improvement. There is a problem of becoming.
[0025]
When the insertion direction is the Y direction, it is necessary to move the entire jumper wire supply unit 101 back and forth while avoiding interference with the jumper wire insertion unit 103 that rotates to change the insertion direction. Accordingly, the steps # 101 and # 105b in FIG. 5 and the jumper wire supply unit 101 shown in FIGS. 6 (e) and 6 (h) are moved forward and backward, and the steps # 102 and FIG. 6 (b) in FIG. The sending out of the jumper wire 104 of the jumper wire supply unit 101 shown in FIG. 5 corresponds to the insertion operation of the jumper wire insertion unit 103 shown in steps # 103 to # 111b of FIG. 5 and FIGS. 6 (c) and (f) to (h). It is connected in series, and in addition to the insertion operation time of the jumper wire insertion unit 103, the forward / backward movement of the jumper wire supply unit 101 and the jumper wire feeding operation time are added, so that the insertion cycle time becomes longer and the productivity improvement is hindered. There is a problem.
[0026]
Further, when the entire jumper wire supply unit 101 is moved back and forth, the large mass of the entire jumper wire supply unit 101 makes it difficult to move quickly.
[0027]
In the present invention, the operation of the jumper wire supply unit and the operation of the jumper wire insertion unit can be performed in parallel, the insertion cycle time is short, and the productivity can be improved. With inserter It is an object to provide a jumper wire insertion method.
[0028]
[Means for Solving the Problems]
Of the present invention Insertion machine In order to solve the above problem, A combined insertion machine capable of inserting both an axial type electronic component and a jumper wire into a board, wherein a jumper wire supply unit for supplying a jumper wire and the jumper wire supply unit are provided separately from each other, The jumper wire supply unit is configured to be able to pivot independently between the same direction as the jumper wire supply direction and the direction substantially orthogonal to the jumper wire supply unit, holding the jumper wire supplied from the jumper wire supply unit, cutting, and inserting direction And a jumper wire insertion portion that inserts into the insertion hole of the positioned circuit board, and the jumper wire supply portion includes a supply nozzle that guides the supply direction of the jumper wire and the supply nozzle. A jumper set at a position near the jumper wire insertion part and at the position where it does not interfere with the insertion part. -After sending the jumper wire to the wire feed position, switch the direction of the supply nozzle to move the jumper wire at the jumper wire feed position to the jumper wire holding position of the jumper wire insertion section, and the supply nozzle is at the jumper wire feed position The jumper wire supply unit inserts the jumper wire insertion portion when the insertion direction of the jumper wire insertion portion is the same direction as the jumper wire supply direction. Move the jumper wire at the jumper wire feed position to the jumper wire holding position of the jumper wire insertion part at the end of the operation, and if the insertion direction of the jumper wire insertion part is a direction substantially perpendicular to the jumper line supply direction, jumper wire The insertion portion holds the jumper wire in the same direction position, and then in the substantially orthogonal direction. Insert the jumper wire turn, back to the same direction after finishing inserting jumpers supply unit while the jumper wire insertion portion is positioned in the substantially perpendicular direction it does not supply the jumper wire to position delivery jumpers It is characterized by that.
[0029]
Further, the jumper wire insertion method of the present invention is to solve the above problems, The jumper wire is supplied sequentially from the jumper wire supply unit, and the jumper wire inserted in the jumper wire insertion unit that can be swung according to the insertion direction of the axial type electronic component and the jumper wire is held, cut, and inserted. In the jumper wire insertion method of inserting into the insertion hole of the positioned circuit board, when the insertion direction of the jumper wire insertion portion is the same direction as the jumper wire supply direction, the jumper wire The supply unit sends out a jumper wire toward a jumper wire delivery position that is set to a position in the vicinity of the jumper wire insertion unit that does not interfere with the insertion unit, and the supply direction of the supply nozzle that sends out the jumper wire. At the end of the insertion operation, change the supply direction of the supply nozzle to the jumper wire holding position of the jumper wire insertion part. The jumper wire insertion position is held in the jumper wire insertion portion, and when the insertion direction of the jumper wire insertion portion is substantially perpendicular to the jumper wire supply direction, the jumper wire insertion portion is After holding the jumper wire in the same direction position, swivel in the substantially orthogonal direction, insert the jumper wire, return to the same direction after the insertion, the jumper wire supply unit interferes with the supply nozzle with the jumper wire insertion unit The jumper wire is not supplied to the jumper wire feed position while the jumper wire insertion portion is positioned in the substantially orthogonal direction. Furthermore, it is desirable to move the jumper wire delivery port of the supply nozzle on the circular orbit.
[0030]
[Action]
Of the present invention With inserter Jumper wire insertion method According to the configuration of In parallel with the cutting / inserting direction adjustment / molding / insertion operation performed by the jumper wire insertion portion, the jumper feed position is in the vicinity of the jumper wire insertion portion and does not interfere with the insertion portion. The jumper wire of the predetermined length is sent out and the jumper wire already in the jumper delivery position is moved to the jumper wire insertion portion in accordance with the cutting / inserting direction adjustment / forming / insertion operation of the jumper wire insertion portion. It is moved to the jumper wire holding position. In this case, the moving portion is mainly a short jumper wire that is cut, molded, and inserted, has a small mass, and requires only a small amount of rotational movement. Therefore, the movement can be performed very quickly.
[0031]
In the conventional example, the jumper wire is sent out from the jumper wire supply unit at the end of cutting / inserting direction adjustment / forming / insertion operation of the jumper wire insertion portion. In this case, the reel wound with the jumper wire is rotated. Compared to the fact that it is necessary and it is difficult to send out the jumper wire at a high speed, the present invention inserts the jumper wire in advance and the operation can be accelerated as described above. Cycle time can be shortened.
[0032]
Further, the present invention is provided with a supply nozzle that sends out a jumper wire to the jumper wire supply unit, and the supply direction of the supply nozzle is determined by the jumper wire holding position direction of the jumper wire insertion portion and the jumper wire delivery position direction of the jumper wire supply portion. The two directions are switched.
[0033]
In this way, the X direction, which is the jumper wire feed-out direction, has a longer length corresponding to the length of the jumper wire to be inserted. The Y direction, which is perpendicular to the jumper wire feeding direction, is shortened corresponding to the diameter of the jumper wire to be held, so the direction of the jumper wire to be inserted is the X direction, and the jumper wire insertion portion is inserted. In the case of not rotating to match the direction, the supply nozzle is set to the supply nozzle feeding direction which is slightly lateral from the jumper wire holding position direction of the jumper wire insertion portion. Send the jumper wire from the position near the jumper wire insertion part to the jumper wire sending position where it does not interfere with the insertion part. Okeru out, can be performed in parallel with operation delivery jumpers jumper wire insertion operation and jumper wire feed portion of the jumper wire insertion portion, it is possible to shorten the insertion cycle time.
[0034]
When the direction of the jumper line to be inserted is the Y direction and the jumper line insertion part rotates in the Y direction, the supply direction of the supply nozzle is slightly changed from the direction of the jumper line holding position of the jumper line insertion part. Even in the direction of the jumper wire delivery position which is on the side, the jumper wire delivered from the supply nozzle interferes with the jumper wire insertion portion. However, if the supply nozzle is directed toward the jumper wire delivery position, the supply nozzle itself does not interfere with the jumper wire insertion portion, so that it is not necessary to move the entire jumper wire supply portion backward and forward in the conventional example. Therefore, the insertion cycle time can be shortened accordingly.
[0035]
Further, according to the present invention, by moving the jumper wire delivery port of the supply nozzle on the circular arc track, the mechanism becomes simple and the operation becomes quick, so that the insertion cycle time can be further shortened.
[0036]
【Example】
A An embodiment in which the jumper wire insertion method of the present invention is used in a combined insertion machine for inserting a axial type electronic component and a jumper wire into a circuit board will be described with reference to FIGS.
[0037]
As shown in FIG. 1, the insertion machine holds, cuts, and inserts the jumper wire supply unit 1 that supplies the jumper wire 4 by a predetermined length and the jumper wire 4 supplied from the jumper wire supply unit 1. A jumper wire that is aligned in a direction and formed into a U-shape that can be inserted into the insertion holes 23 and 23 of the circuit board 22 positioned at a predetermined position by an XY table (not shown), and is inserted into the insertion holes 23 and 23 of the circuit board 22 And an insertion portion 3.
[0038]
A reel 4 a around which a jumper wire 4 is wound is mounted on the jumper wire supply unit 1. The jumper wire 4 wound around the reel 4 a is sent out with the curl removed by the strainer 5. The jumper wire 4 to be sent out is held by a chuck 9 operated by a cylinder 10, and the chuck 9 is pushed by the cylinder 11 and slides on the base 8 to hold a jumper wire from the supply nozzle 2. Send out by length. The stopped jumper wire 4 is sandwiched between chucks 6 operated by a cylinder 7.
[0039]
The supply nozzle 2 projecting from the jumper wire supply unit 1 toward the jumper wire insertion unit 3 is the supply nozzle 2 itself, or a jumper wire that is waiting from the supply nozzle 2 is formed and inserted. In order not to interfere with the jumper wire insertion portion 3 in operation, it has a mechanism that swings outward and retracts. In this mechanism, the rear end portion of the supply nozzle 2 is attached to a swing shaft 12 swingably attached to the base 8, and when the swing shaft 12 is rotated by a predetermined angle by a rotary cylinder 13, The tip of the supply nozzle 2 swings in and out. When the tip of the supply nozzle 2 is swung inward, the supply direction of the supply nozzle 2 is the direction of the jumper wire holding position of the jumper wire insertion portion 3, and when it is swung outward, the supply direction of the supply nozzle 2 is , Jumper wire feed position direction.
[0040]
Since the jumper wire insertion portion 3 does not rotate when inserted in the X direction, the standby jumper wire sent out from the supply nozzle 2 does not interfere with the jumper wire insertion portion 3, and when inserted in the Y direction, the jumper wire insertion portion 3 rotates, so that only the supply nozzle 2 does not interfere with the jumper wire insertion portion 3. The inner diameter of the supply nozzle 2 is slightly larger than the outer diameter of the jumper wire 4, and the predetermined angle of the swing is such that the jumper wire 4 is not bent by the swing, and As described above, the angle is set to achieve the purpose of preventing interference with the jumper wire insertion portion 3. This angle varies depending on the type of the jumper wire 4, but is a small angle of about 5 °, for example.
[0041]
When the supply nozzle 2 is in the direction of sending out the jumper wire, in the case of insertion in the X direction, even if the jumper wire insertion part 3 is in the process of forming / inserting the jumper wire, the jumper wire 4 is sent out for a predetermined length to stand by. Can be made. In the case of insertion in the Y direction, the jumper wire insertion portion 3 cannot send out the jumper wire 4 during the jumper wire forming / insertion operation, but the supply nozzle itself does not interfere with the jumper wire insertion portion 3. It is not necessary to move the necessary jumper wire supply unit 1 backward or forward.
[0042]
The direction of the jumper wire insertion portion 3 is determined by the rotating shaft 24 driven by the driving device 30 through the driving pulley 31, the belt 32, and the driven pulley 33. The rotating shaft 24 is provided with a mechanism that slides in the axial direction while transmitting the rotation to the intermediate portion thereof. The insertion mechanism at the lower portion of the jumper wire insertion portion 3 is determined in the vertical direction by the piston 27 of the cylinder 25 that is operated by the pressure air entering and exiting the vent holes 26 and 29 and moving up and down. A forming lever 21 for forming the jumper wire 4 is provided below the jumper wire insertion portion 3. The forming lever 21 is located directly below the jumper wire insertion portion 3 when forming the jumper wire 4 and swings sideways by a lever mechanism that swings around a fulcrum located above when the forming is finished. Then, the jumper wire insertion portion 3 is retracted to a position that does not interfere with the molding / insertion operation. And at the lower part of the jumper wire insertion portion 3, a fixed blade 14 and a movable blade 15 that receive and cut the jumper wire 4 that passes from the front or swings from the side to the center side, There is a pusher 17 having a holding V groove 16 for holding the jumper wire 4 at the lower end, and an insertion guide 20 that moves up and down. When the insertion guide tips 18 and 18 of the insertion guide 20 are lowered, they are cut by the fixed blade 14 and the movable blade 15 and held in the holding V-groove 16 so as to be positioned on the molding lever 21. The circuit board is lowered while receiving both ends of the formed jumper wire 4 into guide grooves 19 and 19 provided inside the insertion guide 20. It reaches 22 and stops. At this time, both end portions of the jumper wire 4 formed into a U-shape are positioned on the insertion holes 23 and 23 of the circuit board 22. When the insertion guide tips 18 and 18 of the insertion guide 20 are stopped, as described above, the molding lever 21 swings sideways by the lever mechanism and retracts.
[0043]
When the retraction is performed, the insertion guide 20 is further lowered, and the pusher 17 at the lower end of the insertion guide 20 is connected to the jumper wire 4 cut into a U shape as described above. Insert into the insertion holes 23, 23 of the substrate 22. The tip of the jumper wire 4 that is inserted and comes out below the insertion holes 23, 23 of the circuit board 22 is bent and fixed by a fixing portion 34 under the circuit board 22.
[0044]
Next, the operation of the jumper wire insertion method of this embodiment will be described with reference to FIGS.
[0045]
FIG. 2 is divided into a jumper line supply unit 1 and a jumper line insertion unit 3, and the jumper line is inserted in the X direction, which is the same direction as the jumper line supply direction. Since there is what is performed in the Y direction, which is a direction perpendicular to the line supply direction, it is written separately in the X direction and the Y direction. When inserting in the intermediate direction between the X direction and the Y direction, the rotation of the jumper wire insertion portion 3 may be stopped in that direction.
[0046]
In step # 1 of FIG. 2, as shown in FIG. 3A, the supply nozzle 2 of the jumper wire supply unit 1 is retracted in the direction of the jumper wire delivery position by the rotation of the swing shaft 12. At this position, even if the jumper wire insertion portion 3 rotates, the supply nozzle 2 and the jumper wire insertion portion 3 do not interfere with each other.
[0047]
In Step # 2, as shown in FIG. 3B, the jumper wire supply unit 1 sends out the jumper wire 4 for a predetermined length. The jumper wire 4 in the fed-out portion stands by above the outside of the forming lever 21 of the jumper wire insertion portion 3.
[0048]
In steps # 3 and # 8 and thereafter, the jumper line supply unit 1 and the jumper line insertion unit 3 operate completely in parallel.
[0049]
In steps # 3 and # 8, as shown in FIG. 3C, the jumper wire 4 waiting in the jumper wire feed position direction is moved in the jumper wire holding position direction of the jumper wire insertion portion 3. By this movement, the jumper wire insertion portion 3 receives the jumper wire 4 that has moved in the direction of the jumper wire holding position from the side to the fixed blade 14 of the jumper wire insertion portion 3, and the holding V groove 16 of the jumper wire insertion portion 3. Hold on.
[0050]
In steps # 4 and # 9, it is determined whether the insertion direction is the X direction or the Y direction. Each operation differs depending on the insertion direction.
[0051]
For the X direction:

[0052]
In step # 6a, it is determined whether or not to end, and the process ends or proceeds to step # 7a.
[0053]

[0054]
In step # 10a, the jumper line insertion unit 3 cuts the jumper line 4 and retracts the supply nozzle 2 of the jumper line supply unit 1 in the direction of the jumper line delivery position, as shown in FIG.
[0055]
In step # 11a, the jumper wire 4 is formed into a U-shape using the forming lever 21, and the forming lever 21 is retracted and inserted. When the insertion is finished, the retracted forming lever 21 is moved to FIG. 3 (e). Return to the home position as shown in.
[0056]
In step # 12a, it is determined whether or not the process is finished. The process is finished or the process returns to step # 8, and steps (c) to (e) are repeated.
[0057]
After all, in the case of the X direction, the jumper wire 4 is sent out from the supply nozzle 2 to stand by, and the movement from the jumper wire feed position direction to the jumper wire holding position direction is performed by cutting, molding and insertion. Since the short jumper wire is mainly used, the mass is small, and the amount of movement is a slight rotational motion, it is possible to carry out extremely quickly.
[0058]
Therefore, in the conventional example, the jumper wire is sent out from the jumper wire supply unit at the end of cutting / inserting direction adjustment / forming / insertion operation of the jumper wire insertion portion. Compared with the fact that it is necessary to rotate and high-speed operation is difficult, the present invention can shorten the insertion cycle time by sending out the jumper wire in advance and speeding up the operation.
[0059]
For the Y direction:
In the jumper line supply unit 1, following the steps # 1 to # 4, in step # 5b, as shown in FIG. 3F, the jumper line supply unit follows the jumper line cut in step # 10b. 1 supply nozzle 2 is retracted toward the jumper wire feed position.
[0060]
In step # 6b, it is determined whether or not to end, and the process ends or proceeds to step # 7b.
[0061]
In step # 7b, waiting for the direction alignment rotation of the jumper wire insertion portion 3 in step # 11b, the jumper wire shaping / insertion in step # 12b, and the direction alignment return rotation of the jumper wire insertion portion 3 in step # 13b, As shown in FIG. 3 (h), the jumper wire 4 is sent out to stand by, and the process returns to step # 3 to repeat FIGS. 3 (c) and 3 (f) to (h).
[0062]
In the jumper wire insertion unit 3, following step # 1 to # 3, # 8, and # 9, in step # 10b, the jumper wire 4 is cut and the supply nozzle 2 of the jumper wire supply unit 1 is sent out the jumper wire. Retract in the direction of the position.
[0063]
In step # 11b, as shown in FIG. 3G, the jumper wire insertion portion 3 is rotated from the X direction to the Y direction.
[0064]
In step # 12b, the jumper wire 4 is formed into a U-shape using the forming lever 21, and the forming lever 21 is retracted and inserted. When the insertion is completed, the retracted forming lever 21 is moved to FIG. 3 (g). Return to the home position as shown in.
[0065]
In step # 13b, as shown in FIG. 3 (h), the jumper wire insertion unit 3 is rotated back from the Y direction to the X direction, and the jumper wire 4 is sent out from the jumper wire supply unit 1 to stand by.
[0066]
In step # 14b, it is determined whether or not the process is finished. The process is finished or the process returns to step # 8, and FIG. 3C and FIGS. 3F to 3H are repeated.
