Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method and apparatus for attaching terminals to both ends of a plurality of wires, and more specifically, to a method and an apparatus for attaching terminals to both ends of each wire of a plurality of wire groups. Regarding a method and device that can automatically attach one terminal and the other terminal upside down to each other when attaching the terminals, even after each conductor of a plurality of wire groups is crimped to the terminal, the carrier, which is a continuum of terminals, can be individually attached. This carrier effectively prevents wire positioning and mismounting during this terminal mounting process and subsequent processing processes. The present invention relates to a method and apparatus for attaching terminals to both ends of a wire.

[Conventional technology]

As is well known, the technology for connecting wires and terminals has been highly developed, and various technologies are in actual use.

In one of them, a pre-cut and stripped wire is positioned in a crimping machine, and a continuous body, a so-called carrier, in which terminals are connected by a support strip plate is fed to the crimping machine, and the wire conductor is There is a technology that connects terminals by crimping them together. This terminal attachment method and device are as follows:
Initially, the process was carried out one wire at a time, but later, as seen in Japanese Patent Publication No. 58-52309, cutting the wire, stripping the coating, attaching the terminal, etc. Methods and devices have been proposed that allow a group of wires to be processed at once.

Also, a pressure welding connector (having a pressure welding slot having a width narrower than the diameter of the conductor of the coated wire to which a plurality of contacts received in parallel in an insulating housing with an open top to be connected)
When a wire end is inserted into the slot, both ends of the slot pierce the insulating coating of the wire and make electrical contact with the conductor.
As seen in Japanese Patent No. 3888, a technique has been proposed that not only cuts wires and attaches terminals to a plurality of wire groups at once, but also attaches terminals to both ends of each wire in a wire group.

[Problem that the invention seeks to solve]

However, in the prior art, although terminals can be attached to both ends of each wire of a plurality of wire groups, both terminals are attached in the same way. In other words, if one terminal is installed facing upward, the other terminal will also be installed facing upward,
Due to various requirements, electrical connections between various electrical devices or electrical components, where one terminal is attached in a manner that is 180 degrees reversed and the other terminal is not attached, are subject to the above-mentioned requirements. It is also necessary to connect one terminal and the other terminal upside down, as shown in the figure, and the above-mentioned conventional technology cannot meet this requirement.In addition, in the case of a terminal attachment method using a carrier, the above-mentioned Japanese Patent Publication No. 58-52309 describes As shown in Figure 1. Usually, after crimping a terminal to the end of each wire in a group of wires, the support strip that connects the terminals is separated, so that it can be inserted into the terminal housing in the next step. There is a problem in that it is easy to cause mismounting, and various complicated measures must be taken to avoid this.

Therefore, the main object of the present invention is to provide a method and apparatus that can automatically attach one terminal and the other terminal upside down to each other at once when attaching terminals to both ends of each wire of a plurality of wire groups. It is in.

It is an object of the present invention to provide a method and apparatus that facilitate the parallel holding or positioning of a plurality of wires up to the primary process, and that can effectively prevent mismounting and the like during insertion into a terminal housing.

Another object of the present invention is to provide a method for making the cutting length of a plurality of wire groups variable according to the required processing characteristics to obtain wire groups of various lengths with terminals attached to both ends. We are in the process of providing equipment.

Regarding carriers of one old castle 7 and the other area 11) 4110.15
have a common structure. First, one carrier cutting machine 1
0 is shown in FIGS. 9, 12, and 13 (A).

This carrier cutting machine 10 has a lower guide set 115.
and the ram guide 116 by an air cylinder (not shown).
The cutting punch 118 is attached to the ram 117, and the cutter 1111 is attached to the upper ram 115. This is to perform a cutting operation each time the carrier 93 sent from the crimping machine 9 by the forward/reverse feed means 29 of the wire conveying machine 3 stops feeding, and to cut the carrier 93. Forward/reverse feeding means 2
By making the feed stroke of θ variable, the carrier length is selected and cut according to the number of poles of the terminal housing to be connected. That is, if the terminal housing to be connected is, for example, three poles, the plurality of wire groups with carriers attached are fed by the forward and reverse feeding means 29 of the wire conveying machine 3 by an amount corresponding to the length of the three poles,
When the feed is stopped, a cutting operation is performed to cut the carrier into lengths corresponding to three poles. The same applies to the carrier cutting machine 15 in the other area 11, as shown in FIGS. 16, 19, and 20 (A). 120 is a die set, 121 is a ram guide, 1
22 is a ram, 123 is a cut punch, and 124 is a cut die.

Based on the above configuration, a series of operations will be explained in the order shown in FIGS. 2 to 20 as follows. 2 and 3 show that after a terminal is attached to each tip of a wire group 20 consisting of a plurality of wire groups, six wires 125a to 125f in this example, in a pre-process, this wire group is While being clamped by the clamping means 19 of the conveyor @3, the front zone 1 is moved by the forward and reverse feeding means 28.
It is shown returned to the clamp position. In this example, Wire Crimp III! 9 cuts the carrier into six pieces at a time, and the carrier cutter 10 cuts the carrier into lengths for three terminals according to the number of poles of the terminal housing to be connected, and then returns it to the front zone 19 clamping position. Here is an example.

After this state, the air cylinder 50 constituting the advancing/retracting means 52 of the wire length measuring machine 5 moves forward according to a control command from the control system, and the clamping means 47 consisting of a pair of fingers 42 and 43 moves forward with its mouth open. It passes between the blades of the wire cutting machine 4 and reaches a position in front of the clamping means 18 of the wire conveying machine 3 in the front side zone 1, and clamps the tips of the plurality of wire groups 20 at that position. This clamping is performed by operating a 45.4 ft air cylinder according to a control command from a control system. At this time, the upper and lower fingers 16 of the clamping means 13 of the wire conveying machine 3, I? Then, as shown in FIG. 4, the air cylinder 5° constituting the advance/retreat means 52 of the wire length measuring machine 5 moves backward, and the clamp means 47 passes through the cutting position of the wire cutting machine and retreats.

At this point, the wire group is pulled out toward zone 2 on the back side, but as shown in FIG. The slider 54 is moved backward by the rotation of the slider 54. The table 43 moves backward as shown by the arrow 126 due to the backward motion of the forward/reverse feed means 56, and the clamp means 47 moves rearward, so the wire group 20 passes through the clamp position on the far side and moves behind it. It is pulled out a predetermined length. This plural wire group 2
When drawing out the wire group 20, the length of the wire group 20 can be made longer by varying the length of the drawing, that is, the amount of movement of the table 43 by the servo motor 55 of the forward/reverse feed means 56, depending on the processing request. 6.Then, the air cylinder 18 of the clamping means 19 of the wire conveying machine 3 operates, the upper finger 16 moves downward, and the wire is The servo motor 72 that grips the group 20 and constitutes the forward/reverse feed means 74 of the wire reversing machine 12 rotates forward in response to a control command from the control system, and feeds the table B7 in the forward direction through the operation of the lead spline mechanism 73. , the clamping means 80 consisting of holders 57, 58 on the table 67 is advanced in the forward direction. That is, the clamping means 60 is advanced to a position where it can clamp the wire group 20 pulled out in the above step, and the upper holder 57 and the lower holder 58 are positioned above and below the wire group 2o. Then, the air cylinder 58 of the clamping means 60 of the wire reversing machine 12 operates, and the lower holder 5
8 is moved upward to clamp the wire group 20 between the holders 57 and 58. That is, the plurality of wire groups 20 are clamped at both the clamp position of the front side zone 1 and the clamp position of the rear side zone 2, and are held tensioned in both directions. FIG. 6 shows this state. Then, as shown in FIGS. 6 and 7, the wire group 20 held under tension is cut by the wire cart machine 4 located at the cutting position between the two clamp positions. That is, the air cylinder 32.9 of the wire cutting machine 4 is activated by the control signal of the control system.
3 to move the sliders 30 and 31 up and down, and the cutting blades 34 and 35 partially cut the wire group 20 in the front zone 1 and the wire group 20 in the back zone 2. That is, the conductor 40 of each wire is cut. Insulating coating 41 at the cut tip of each wire of the plurality of wire groups 20 located in the front side zone 1, and at the cut rear end of each wire of the plurality of wire groups 20 located in the back side zone 2. This is to cut the insulating coating 41 in the case. At this time.

As shown in FIGS. 8(A) and 8(B), the air cylinder 23 constituting the advancing/retracting means 25 of the wire conveying machine 3 operates to draw the clamping means 19 toward the front side, and at the same time, the reversing machine 12 Air cylinder 6 constituting advancing/retracting means 66
5 operates to pull the clamping means 60 to the back side, so that the insulating coating 41 at the tip of each wire 125a-125f of the front wire group 20 is removed, and each wire 125a-125f of the back wire group 20 is removed. The insulating coating 41 at the rear end is removed.

Desirably, the residue of the insulating coating 41 is passed through the nozzle 129.
It is best to blow air out from the wire so that no insulation coating residue remains at the wire cutting position. After this, terminals are crimped to the tips of each wire 125a to 125F of the wire group 20 located in the front zone 1. As the process progresses, terminals are crimped onto the rear ends of the wires 125a to 125f of the wire group 20 located in the back zone 2. First, the wire group in the front zone 1 is crimped. 20, the plurality of wire groups 20 in the front zone 1 are clamped by the upper and lower fingers 16, 1.7 of the wire conveying machine 3 in a view substantially perpendicular to the wire conveying direction. At this point, the terminal is transported to the terminal crimping position I19, which is located in the direction of Ichiko Castle 7 in the left-lateral direction.

That is, as shown in FIG. 9, the servo motor 2 of the wire conveying machine 3 is driven in the normal rotation by a control command from a control system (not shown), and the table 22 is moved through the driving and sliding movement of the lead spline sheet 26 and the slider 27. moves toward the crimping machine 9 as shown by arrow 127 in FIG. As a result, the plurality of wire groups 20 in the front zone l are connected to the crimping machine 9.
will be moved to the front.

Then, at the conveyance limit position, the air cylinder 23 constituting the advancing/retreating means 25 of the wire conveying machine 3 moves forward, pushing forward each tip of each wire 125a to 125f of the wire group 20, and pushing it forward in the crimping machine 9. Position to crimp position. For this crimping machine 9, as shown in FIGS.
3 is carrier sending 4I! Sent by 8. That is, for each rotation of the pulse motor 75, the crank plate 76 rotates once, and the feed lever 78 reciprocates once. Due to this reciprocation, the feed pawl 80 makes one roll due to the action of the cam surface and the return force of the spring 77, and each time this roll is made,
The feed end of the claw 80 fits into the feed hole 84 of the carrier 83 and feeds it toward the crimping machine 9.

Therefore, in the primary process of crimping 41!9, six wires 125a to 125f are crimped at one time as shown in the example in this figure.
When connecting the terminals 82 to each tip of the crimping machine 9, the pulse motor 75 of the carrier feeder 8 rotates six times to roll the feed claws 80 six times for each processing step of the crimping machine 9. , the carrier 83 has a length corresponding to six terminals, and is placed at the crimping position of the crimping machine, that is, between the core wire punch 38, the insulation coating punch 100, the core wire anvil 103, and the insulation coating anvil 104 of the crimping machine 9. As explained earlier, six wires 12 of the wire group 20
Each time 5a to 125f are positioned at the crimping position, carriers 93 for six terminals are positioned there.

In this way, carrier 83 for 6 terminals and 6 wires 1
When the wire group 20 consisting of wires 25a to 125f is positioned, the crimping machine 9 of Ichikojo 7 starts the crimping process as shown in FIGS. 11(A) and 11(B). That is, the core wire punch 89 is lowered, and each wire 12 is removed by it and the core wire anvil 103.
5a -125F conductor 40 is attached to the tip of the terminal 82 by crimping, and the insulation coating punch 100
is lowered, and the insulation sheath 41 of each wire +25a''+25f is connected to the terminal 8 by it and the insulation sheath anvil 104.
It is attached to the rear part of 2 by crimping. At this time, in the prior art, the carrier 83 was also cut into individual terminals and the support strip was separated, but in this invention, the carrier 83 corresponds to the number of terminals to be attached in one crimping process, that is, in this example, 6 terminals.
It is simply cut to the length of the required number of terminals.

Next, after this crimping process, the plurality of wire groups 20 are moved along the return direction to the forward/reverse feed means 29 of the wire conveying machine 3 while the carriers 83 having the length corresponding to the number of the attached terminals are attached.
The carrier cutting machine 10 is sent by finely controlling the servo motor 28 that makes up the carrier cutting machine 10. That is, the carrier 83 is intermittently fed to the position of the carrier cuff 1114 by a length corresponding to the number of poles of the terminal housing to be connected, and the carrier 83 is cut to a length corresponding to the number of poles of the terminal housing. Divide into carrier groups of each length.

A plurality of wire groups each having carriers each having a length corresponding to the number of poles are attached. More specifically, let us take as an example a case where the carrier 83 having a length of 6 terminals is cut into 3 terminal lengths each after each of the 6 terminals is attached in the previous step, in order to make 3 terminals each. Then, the table 22 is intermittently fed to the carrier cutting machine 4 by the length of the carrier corresponding to the length of the three terminals by the servo motor 28 constituting the forward/reverse feeding means 28 of the wire conveying machine 3. After securing this feed, when stopping, the cut punch 1 is inserted as shown in FIGS.
Move 18 down 9 Cut punch 118 and cut die 1
19, the carrier 83 is cut into lengths of three terminals each. Therefore, a terminal 82 is attached to the tip of each of the three wires L25a-125c, and these three terminals are continuous as a carrier, but are separated from the three wires 12te d-125f of the l group. There is. Of course, these three wires 125d to 125f also have a terminal 82 attached to each tip, and these three terminals are continuous as a carrier. In this way, in the crimping process, the carrier 83 is not divided into individual terminals, but is simply cut into carrier parts.
Since the carrier is simply divided into groups during the process, it is ensured that multiple wires are held in parallel during the next process, especially when assembling the terminal housing, and mismounting etc. when inserted into the terminal housing is prevented. After this step, the wire group 20 is returned to the configuration shown in FIG. That is, the tips of the wire group are attached.

On the other hand, while the ends of the wire groups 20 in the front zone 1 are subjected to terminal crimping and carrier cutting, the wire groups 20 in the back zone 2 are similarly processed. That is, in the back zone 2, the plurality of wire groups 20 cut by the wire cutting machine 4 were clamped by the clamping means 60 consisting of a pair of holders 57 and 58 of the wire reversing machine 12. The reversing means 71 consisting of the low reactor unit rotor 8 of the reversing machine 12 is operated by a control command from a control system (not shown) to rotate the rotating shaft 69. As a result, the rotating arm 70 is rotated 180 degrees until it hits the stopper 128, so that the clamping means 60, that is, the pair of holders 57 and 58 are rotated 180 degrees, as shown in FIG. In this case, it is recommended to interpose an appropriate throttle in the back pressure removal system that constitutes the air pressure control system of the low reactor unitaro 8, so that various adjustments can be made so that the rotating arm can be reversed at an appropriate speed. , a plurality of wire groups 2 located in the back zone 2
0 is reversed from the previous position, and the rear end of the wire group 20 is located in front of the crimping machine 14 in the other region 11. Here, the air cylinder 65 of the wire reversing machine 12 is advanced to push the rear end of the wire group 20 forward to position the rear end of the wire group at the crimping position of the crimping machine 14. Here, as in the front zone 1, a carrier 83 is a continuous body of terminals 92 that are supplied one after another in accordance with the crimp tact as shown in FIG.
18(A) CB), the conductors 40 at the rear ends of the wires 125a to 125f of the plurality of wire groups 20 are crimped and connected, and the carrier 93 is connected as shown in FIG. The carrier is cut to the same length as the carrier cut length during the crimping process of the multiple wire groups in the front zone 1. That is, since this example shows an example in which terminals are attached to six wire groups 20, the carrier 93 is also cut to a length corresponding to six terminals.

What is important here is that the terminal mounting here is 180 degrees opposite to the terminal mounting manner in the front zone 1. Therefore, terminals are attached to the leading and trailing ends of each wire of the multi-wire group 20 at the same time, but in opposite directions. Thereafter, with the carrier 93 of this length attached, the plurality of wire groups 20 are pitch-fed along the forward direction by the servo motor 72 that constitutes the forward-reverse feed means 74 of the reversing machine +2, and are transferred to the front zone 1. Similarly, as shown in FIGS. 20(A) and 20(B), the carrier car/
) Cut the carrier 93 into lengths equivalent to the number of poles of the terminal housing by intermittently feeding the carrier 93 slightly to @ 15, thereby cutting the carrier 93 into lengths equivalent to the number of poles in the same way as in the front zone 1. Obtain multiple groups of wires with Yaria attached. In this example, the carrier is cut to the length of each of the three terminal trees. Thereafter, the wires are released at that position, and these operations are repeated continuously to connect terminals to both ends of the wires one after another. After crimping, when the carrier in which a predetermined number of terminals are connected is sequentially sent to the carrier cutting position and cut, the feed length per cut, that is, the forward/reverse feeding means 29 of the wire conveying machine 3 or wire reversing @I2 is determined.
．． By making the feeding pitch of 74 variable according to the number of terminal housing poles to be connected, carriers with a predetermined number of terminals connected can be divided into carrier groups with lengths corresponding to various number of poles. It is something. On the other hand, various conventionally known sensors may be used to detect the position, movement length, rotation amount, timing, etc. of each device for carrying out the above-mentioned control in this device.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, when attaching terminals to both ends of each wire of a plurality of wire groups, one terminal and the other terminal are automatically returned to each other vertically at the same time. It has the advantage that it can be attached to

In addition, even after terminals are crimped to both ends of each wire in a group of wires, the support strips of the terminals do not need to be separated. Easy to hold or position. In addition, mismounting and the like during insertion into the terminal housing can be effectively prevented. Furthermore, since the cutting lengths of the plurality of wire groups can be variously selected, the wire groups with terminals attached to both ends can be processed into various lengths. Moreover, various advantages such as being able to select and process the carrier after terminal crimping to a required length according to the number of poles of the terminal housing are made possible.
