BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal insertion device capable of simultaneously positioning a connector housing with respect to a terminal in a terminal automatic insertion process to eliminate defective terminal insertion and simultaneously forming a wire harness. The present invention relates to a terminal insertion method and a connector holding structure used therefor.

[0002]

2. Description of the Related Art FIG. 31 shows an apparatus for inserting a terminal into a connector housing by using a connector receiving member. This device 71 includes a column 73 on a frame bed 72.
It has an X-axis rail 74 supported by. A terminal insertion head 75 is slidably engaged with the X-axis rail 74 and is driven in the X direction by a rack and pinion (not shown).
The terminal insertion head 75 includes a gripping hand 77 for gripping the wire-equipped terminal 76, a cylinder 78 for moving the gripping hand 77 up and down, and a cylinder (not shown) for moving the gripping hand 77 forward and backward (Y direction). ) And.

Further, a plurality of connector receiving members 79 are arranged in a horizontal row on the frame bed 72 and can hold connector housings 80 having various shapes. As shown in FIG. 32, the connector receiver 79 is bolted onto the guide rail 81, for example. The connector housing 80 is housed in the opening 82. The connector housing 80 is pressed and fixed to a rod 84 of an actuator (cylinder) 83 via a rotary link 85, for example. The supply of the connector housing 80 to the connector receiving member 79, the insertion of the terminals, and the removal of the connector (the connector housing 80 with the terminals inserted) are all performed automatically.

Terminal 7 with electric wire to connector housing 80
6 is inserted by the XY movement of the terminal insertion head 75 shown in FIG. The terminal insertion head 75 picks up the wire-equipped terminal 76 from a clamp rod (not shown), and moves it along the X-axis rail 74 to above the required connector housing 80.
Next, the gripping hand 77 is lowered by the cylinder 78 to position the terminal in the rear opening of the required terminal accommodating chamber 86. Then, the gripping hand 77 advances by a cylinder (not shown), and the terminal 76 is inserted into the terminal accommodating chamber 86.

[0005]

However, in the above-mentioned conventional apparatus, when the terminal is inserted, the movement dimension error A of the terminal insertion head 75 in the X direction and the stop position of the terminal gripping hand 76 as shown in FIG. error B and, since the C ₁ to Cn (set position error of the connector housing) assembling position error of the connector receptacle 79 is accumulated, poor terminal insertion position accuracy, the terminal insertion rate is lowered . In order to improve this, it is necessary to position each terminal accommodating chamber of the connector housing 80 by teaching, which requires a great number of man-hours for program creation.

Further, if the structure is such that the connector housing 80 is fixed to the connector receiving member 79 by the actuator 83, the cost becomes high and the receiving device itself becomes large. Further, although the housing supply, the terminal insertion, and the connector take-out are automatically performed, as shown in FIG. 33, when the connector 80 is taken out, the respective connectors are positioned in parallel while being in the position of the receiving jig 79. Therefore, there was a troublesome work of shaping the wire harness (work for defining the position and direction of the connector, etc.).

In view of the above points, the present invention improves the accuracy of the terminal insertion position to eliminate the terminal insertion failure in the connector housing, and at the same time shapes (shapes) the wire harness, and further increases the cost of the connector receiver. It is an object of the present invention to provide a terminal insertion device and a terminal insertion method that can prevent the occurrence of enlargement and enlargement, and a connector holding structure used therefor.

[0008]

In order to achieve the above object, the present invention provides a Y-axis rail movable along an X-axis rail, and a terminal insertion head movable along the Y-axis rail. An X'-axis rail that is movable along the Y-axis rail and shorter than the X-axis rail, and is movable along the X'-axis rail, can be moved up and down in the Z direction, and can be rotated in the θ direction by a driving means. A movable chuck part, a connector receiver that is gripped by the chuck part while holding the connector housing, and a receiving base that is fixed to the connector position of the wire harness on the frame bed and is capable of holding the connector receiver. It is based on a terminal insertion device composed of a tool. It is also effective that the receiving base member has a notch space for inserting an electric wire. It is also effective to provide a reflection type beam sensor for the connector receiving member on the chuck portion side and provide a reflection plate for the reflection type beam sensor on the connector housing mounting surface of the bottom plate portion of the connector receiving member. . Further, the connector receiving member is set on the receiving base member arranged corresponding to the connector position of the wire harness, and the connector receiving member is picked up from the receiving base member by the chuck portion moved onto the connector receiving member, By moving the chuck portion along a short rail, the terminal accommodating chamber of the connector housing on the connector receiver is aligned with the terminal of the terminal insertion head, and after inserting the terminal into the terminal accommodating chamber, A terminal insertion method of returning the connector receiving member to the receiving base member by the chuck portion is also adopted. It is also effective to rotate the connector receiving member when returning the connector receiving member to the base member so that the connector on the connector receiving member is aligned with the connector mounting angle of the wire harness.

Further, a bottom plate portion on which the connector housing is placed, a centering pin and a positioning pin projecting from the bottom plate portion, an annular locking groove provided around the centering pin, and one side of the bottom plate portion. A first side plate portion that is erected upright and has an abutting reference surface against one side surface of the connector housing, and an engaging portion for a pair of chuck plates, and is provided on the other side of the bottom plate portion. A connector base including a side surface pressing means, an engagement hole for the centering pin, a ball plunger that engages with the locking groove, and a receiving base tool including a plurality of position selection holes for the positioning pin. Adopt a structured connector holding structure. It is also effective that the position of the lead wire from the connector housing is offset from the centering pin. Further, the pressing means is a leaf spring having a locking projection that engages with an upper edge of the connector housing, and a stepped portion is formed on the first side plate portion so as to face the locking projection. A structure in which the pressing means is a second side plate portion adjacent to the other side surface of the connector housing, and a first ball plunger provided on the second side plate portion and pressed against the other side surface of the connector housing, and the connector housing A second ball plunger engaging with the upper edge of the other side surface is provided on the second side plate portion, and a third ball plunger engaging with the upper edge of the one side surface of the connector housing is provided on the first side plate portion. The structure provided, the locking projection, the stepped portion, and the second and third ball plungers are located at a position ⅔ of the length in the front-rear direction of the connector housing from the end portion on the terminal insertion opening side of the connector housing. Stops that contact the front end and the rear end of the connector housing are provided at the front end and the rear end of the bottom plate portion, respectively, and the guide inclined surfaces for guiding the connector housing are formed at each stop part. The structure is also effective. Further, one of the pair of chuck plates has a vertical ridge and the other has a horizontal ridge, and the engaging grooves for the vertical ridge and the horizontal ridge are provided in the orthogonal direction on the first side plate portion. The vertical projections and the horizontal projections have straight surfaces parallel to each other on both sides, and guide taper surfaces that follow the straight surfaces, and each engagement groove is formed to have a substantially rectangular cross section. It is also effective to have a structure having parallel contact surfaces with respect to each straight surface.

The operation will be described below. A connector receiver is retained on the receiver base. A connector housing is retained on the connector receiver. The centering pin of the connector receiving tool is inserted into the engaging hole of the receiving base tool. The connector housing is elastically held on the connector receiver by the pressing means. The chuck moves on the X-axis rail and the Y-axis rail to reach the connector receiver, and after lifting the connector receiver, inserts a terminal along the Y-axis rail (or on the X-axis rail and the Y-axis rail). Move to the head side. The terminal housing chamber of the connector housing is then aligned with the terminals of the terminal insertion head by the short X'axis rails (or rails). Since the chuck part separates the connector receiving tool from the receiving base tool, the mounting dimension error of the receiving base tool is irrelevant. Further, since the X'-axis stroke is short, the movement dimension error of the connector housing is extremely small. After inserting the terminals into the connector housing, the connector receiving member is returned to the receiving base member. At this time, the chuck portion is rotated, the positioning pin of the connector receiving tool is inserted into a required position selecting hole of the receiving base tool, and the connector on the connector receiving tool is arranged in a wire harness form. In addition, the electric wire is inserted into the notch space of the receiving base tool, and interference between the jig and the electric wire is prevented. Since the receiving base tool is fixed at the position corresponding to the connector of the wire harness, the electric wire led out from each connector is also routed (wired) in the wire harness form.

In the above manufacturing process, the reflection type beam sensor and the reflection plate detect the remaining connector housing on the connector receiving member and the detachment of the connector receiving member from the base member. Also, by pulling the lead wire from the connector housing, a twisting force due to the wire position offset acts between the centering pin of the connector receiver and the engagement hole of the base member. Is pulled up against the bias of the pressing means. The connector housing is positioned laterally by the pressing means on the connector receiver, and is positioned vertically by the locking projection of the leaf spring, the stepped portion of the side plate or the ball plunger, and is positioned forward and backward by the stop on the bottom plate. It Since the connector housing is supported on the connector holder from the rear end by a locking projection at a position ⅔ of the housing length, the lever is used as a lever when pulling the wire backward when checking the terminal locking. When the housing is prevented from rotating, the connector housing is easily separated from the connector receiver when the wire is pulled up when the sub-harness is taken out, and when the terminal tip hits the upper part of the connector housing rear end during terminal insertion, the connector housing Is prevented from rotating. Further, since the protrusions of the chuck plate and the engaging grooves of the connector receiving member are in contact with each other on the straight surfaces and the contacting surfaces on both sides which are parallel to each other, the connector receiving member is firmly fixed to the chuck plate in the XY directions. Even if an external force is applied to the connector housing, the chuck plate does not open and the connector receiver does not tilt.

The chuck portion 6 is composed of a chuck cylinder 22 and a pair of openable and closable chuck plates 23. The chuck plate 23 can hold the connector receiver 7. A connector housing 12 is held in the connector receiving member 7 with a rear opening 24 of the terminal accommodating chamber directed toward the terminal insertion head 4. Further, a rotary actuator 25 as a chuck unit driving means is provided on the substrate unit 19, and the actuator 25 moves the chuck unit 6 up and down through a belt 26 and belt pulleys 27 and 28.
It is possible to rotate integrally with and within a range of 360 degrees.

The terminal insertion head 4 is slidably installed on the Y-axis rail 3 behind the chuck section 6, and the slide section 30 of the substrate section 29 is mounted on the guide section 13 of the Y-axis rail 3.
Can be moved in the Y direction separately from the X'-axis rail 5 by a belt driving mechanism (not shown). The terminal insertion head 4 is almost the same as that proposed by the applicant in Japanese Patent Application No. 6-89507, and includes an elevating cylinder 31 fixed to the base plate portion 29 and a horizontal direction connected to the elevating cylinder 31. The forward / backward cylinder 32, the chuck cylinder 33 connected to the forward / backward cylinder 32, and the chuck cylinder 33.

Since the X'-axis rail 5 and the terminal insertion head 4 are engaged with the same Y-axis rail 3, the connector housing 12 can be positioned with respect to the terminal 35 only by the movement of the X'-axis rail 5 and the X'-axis. Since the rail 5 is extremely short, almost no positioning error occurs.

The terminal insertion head 4 is fixed not in the Y-axis rail 3 but in one reference position in the X-direction so that the X-axis rail 2 moves and the X'-axis rail 5 engaged with the Y-axis rail 3 moves. With the correction movement (fine adjustment), the terminal accommodating chamber 24 of the connector housing 12 with respect to the terminal 35 of the terminal insertion head 4 is moved.

The centering pin 40 has a diameter slightly smaller than that of the engagement hole 57 so as to be fitted into an engagement hole 57 of the receiving base member 9 which will be described later, and has a tip for insertion into the engagement hole 57. It has a tapered chamfer 40a and a peripheral groove (locking groove) 51 for locking. The positioning pin 41 is formed to have a smaller diameter than the centering pin 40 and has a tapered chamfered portion 41a at the tip. The centering pin 40 is
It is provided near the side plate portion 38 so that the pulling-out force from the chuck portion 6 directly acts.

The receiving base 9 is a disk-shaped lower flange plate 54 fixed to the frame bed 8 with bolts 53.
And a disc-shaped upper flange plate 56 that is integrally provided at the tip of the column 55 and that holds the connector receiver 7, It is arranged corresponding to the connector wiring position of the harness. In addition, the support column 55 is connected to the flange plates 54, 5
Needless to say, the receiving base member may be formed in a cylindrical shape with the same diameter as 6.

A vertical engaging hole 57 for the centering pin 40 of the connector receiving member 7 is provided in the center of the upper flange plate 56, and the centering pin 40 is locked inside the engaging hole 57. A ball plunger (engagement ball) 58 for the groove 51 is provided so as to project under the spring bias. Around the engagement hole 57, a plurality of vertical position selection holes 59 for the positioning pin 41 of the connector receiving member 7 are provided at equal intervals. By inserting the positioning pin 41 into the required position selection hole 59, the circumferential angle of the connector receiver 7 is determined, whereby the connector (12) is swung and positioned at an angle corresponding to the shaping form of the wire harness. It

The angle of the connector receiver 7 is set after the terminal 35 is inserted into the connector housing 12, and the terminal insertion is performed by positioning (opposing) the connector housing 12 at a right angle to the longitudinal direction of the terminal 35 on the insertion head 4 side. Is done. That is, as shown in FIG.
Then, the connector receiver 7 is grasped and lifted, and is positioned so as to face the front of the terminal insertion head 4. Next, the terminal insertion head 4 moves forward to insert the terminal 35 into the required terminal accommodation chamber 24 of the connector housing 12.

A terminal 35 to another adjacent terminal accommodating chamber 24
Is inserted by moving the chuck portion 6 along the X′-axis rail 5. Terminals 35 are provided in all terminal accommodating chambers 24.
When is inserted, the rotary actuator 27 is rotated to rotate the chuck portion 6 to a desired angle. In this state, the chuck portion 6 receives the connector receiving tool 7 and returns it to the base tool 9. As a result, the connector 12 is angled and arranged in a wire harness shape.

4 and 5 show the shape of the wire harness. That is, as shown in FIG. 4, with respect to a plurality of receiving base members 9 _{1 to} 9 ₅ arranged in advance on the frame bed 8 in the connector position form of the wire harness, the chuck portion 6 is provided with the respective connector receiving members 7 _{1 to} 7 _5. Is fixed at the required angle. Connector 12 ₁ on each connector receiver 7 _{1 to} 7 ₅
Electrical wires 36 _{1 to} 36 ₅ derived from ˜ 12 ₅ are gathered between a pair of focusing pins 60 and routed as a trunk line 61 on the left and right.

Next, as shown in FIG. 5, each of the connectors 12 _{1 to} 12
₅ was removed from the receptacle 7 _{1-7 5} connectors, wires 36 ₁
By removing the 36 _5, 61 from the focusing pin 60, the form of the wire harness 62 is obtained. Connector 1 in the figure
Angles (directions) 2 ₁ , 12 ₂ , and 12 ₅ are preset. By setting this angle, the shortage of the wire length of the electric wire 36 when it is placed on the knotting jig (tapping the wire harness 62 or the like) in a later step is eliminated.

FIG. 6 shows an example in which the receiving bases 9 _{1 to} 9 ₄ are arranged close to each other to save space (smaller size) of the device 1, and the connector bases 7 ₂ and 7 ₃ are arranged on top of each other. Connector 1
The electric wires 36 ₂ and 36 ₃ derived from 2 ₂ and 12 ₃ are arranged through an annular notch space 63 between the upper flange plate 56 and the lower flange plate 54 of the receiving base tools 9 ₁ and 9 ₄ as shown in FIG. To be searched. If this notch space 63 does not exist, the electric wire 36 ₃ may be lifted and pinched between the upper flange plate 56 and the bottom plate portion 37 of the connector receiving member 7 ₄ and may be damaged, and the receiving base device 9 of the present embodiment. The shape of has the effect of preventing it.

Further, even if the adjacent connector receivers 7 ₁ and 7 ₂ are at a distance such that they interfere with each other as shown in FIG. 8, the interference is prevented by swinging the angle of _one connector receiver 7 ₁ . This contributes to space saving of the device 1. By the terminal insertion device 1, supply of the housing 12 to the connector receiver 7, insertion of terminals, shaping (formation), and taking out of the product 62 are collectively performed.

The connector holding structure by the connector receiving member, the receiving base member and the chuck portion will be described in detail below. FIG. 9 shows a connector base 90 and a base base 91.

The position of the lead-out electric wire 94 from is offset from the centering pin 95 by about half the length of the connector housing 93.

Therefore, by pulling up the electric wire 94 with a hand (not shown) as shown by arrow A, the connector 92 is separated from the receiving member 90 against the bias of the leaf spring 98. At this time, since the centering pin 95 and the electric wire pull-up position are offset from each other, a force in the twisting direction acts on the centering pin 95 to prevent the connector receiving member 90 from coming off the base device 91. If the diameter of the engaging hole 99 is too large with respect to the centering pin 95, the centering pin 95 will come out without being twisted, so that the fitting is made to be a clearance fit as described above. The detaching operation of the connector receiving member 90 from the receiving base device 91 can be easily performed by gripping the side plate portion 100 with the chuck plate and lifting it with a force greater than the pressing force of the ball plunger 97.

Only the ball portion 106a of the third ball plunger 106 projects from the inner surface of the first side plate portion 104. The inner surface of the first side plate portion 104 acts as a reference surface 113 that contacts the connector housing 102. The second side plate portion 105 is located slightly away from the connector housing 102, and has the first and second ball plungers 107 and 108.
The main body 110 of the second side plate portion 105 is screwed in so as to slightly project from the inner surface of the second side plate portion 105, and the ball portions 107a, 108

The connector housing 127 will rotate forward with the ball portions 140a and 142a as fulcrums due to the sliding resistance with the terminal 136. The power to work is working. As the ball portion 142a ′ is closer to the front end of the connector housing 127 as shown in FIG. 21, a larger force is required to suppress the turning power. Therefore, by arranging the ball plungers 140 and 142 at a position ⅔L from the front end of the stop protrusion 144, as in the previous example,
The holding force at the time of confirming tension, the detachability of the connector, and the terminal insertability can be improved.

FIG. 28 shows an X-axis rail 175, a Y-axis rail 176, and X'in the terminal inserting device as shown in FIG.
The reflection type beam sensor 179 is provided on the side of the chuck portion 178 which is movable by the shaft rail 177.
By providing a reflection plate 183 for the beam sensor 179 on the connector mounting surface 182a of the bottom plate 182 of the connector receiver 181 on the connector 80, it is possible to detect the presence or absence of the connector housing and the failure of the connector receiver 181 to come out. Here is an example.

The reflection type beam sensor 179 has a bolt 188 via a bracket 187 on a side surface of a substrate portion 186 to which a cylinder 185 for raising and lowering the chuck plate 184 is fixed.
It is fixed at. The lead wire 18 of the beam sensor 179

FIG. 29 shows a state in which the terminal 194 is inserted into the connector housing 193 on the connector receiver 181. In the case where the connector housing 193 has only one terminal accommodating chamber, the tip of the terminal 194 should be the connector. When the terminal 194 is not inserted by hitting the end surface of the housing 193, only the connector housing 193 is left on the connector receiver 181 when the sub-harness 195 is grasped and pulled up by the hand 196 as shown in FIG. There is a concern that 195 will be washed away unfinished. In order to detect this, the connector housing 193 is attached to the connector receiver 181 with a chuck (not shown).
When the beam is supplied to the connector, the connector 181 is irradiated with the beam 192 by the beam sensor 179, and the reflection plate 18 on the receiver is received.

Is detected. There is also a method of individually providing a sensor, a limit switch or the like on the connector receiving member, but the wiring is troublesome and the number of input points must be secured, which is far from the beam sensor.

[0068]

As described above, according to the present invention, since the chuck portion separates the connector receiving member from the receiving base member, the mounting dimension error of the receiving base member has no relation.
Further, since the displacement amount of the X'-axis rail is short, the movement dimension error of the connector housing becomes extremely small. Further, since the X'-axis rail, that is, the chuck portion and the terminal insertion head are coaxially engaged with each other, the movement dimension error due to the X-axis rail is eliminated. As a result, the positioning accuracy of the terminal accommodating chamber of the connector housing with respect to the terminal is improved, and defective insertion of the terminal is eliminated. Further, since the receiving base is arranged at the position corresponding to the connector of the wire harness, the lead wires from each connector are arranged in a wire harness form, and the connector receiver is arranged so as to match the connector angle of the wire harness. Therefore, the wire harness is shaped at the same time in the terminal inserting step, thereby reducing the burden of the subsequent steps and improving the efficiency of wire harness production.

Further, since the connector housing has a simple structure in which the connector housing is locked by the biasing force of the leaf spring or the ball plunger, the connector receiver is made compact and the completed sub-harness can be pulled up by a hand or the like. As a result, the leaf spring and the ball plunger are bent and the connector is automatically disengaged from the connector receiving member, which enables automation of harness production. Further, since the electric wire is inserted into the notched space of the receiving base device, interference between the connector receiving device or the base device and the electric wire can be prevented, and the receiving base devices can be arranged close to each other, and the connector receiving device can be rotated. Space saving is achieved in combination with the close placement by the dynamic placement.

In the sub-harness manufacturing process, the reflection type beam sensor and the reflection plate detect the remaining connector housing on the connector receiving member and the connector receiving member coming out of the base member. It is possible to repair defective connectors and connector removal on the spot. Further, by pulling the lead wire from the connector housing, the connector housing can be smoothly detached from the connector receiving member, so that the manufacturing can be automated. Further, since the connector housing is positioned on the connector receiving member in the up, down, left, right, front, and rear directions, reliable terminal insertion is possible. Further, by holding the connector housing on the connector receiver from the rear end at a position of ⅔ of the housing length as a fulcrum, there is no displacement of the housing at the time of terminal abutting, and the terminal locking confirmation property and The detachability of the connector from the connector receiver is improved. Further, the connector receiving member is firmly fixed to the chuck plate in the XY direction by the straight surface and the contacting surface on both sides of the protrusion of the chuck plate and the locking groove of the connector receiving device being in parallel contact with each other.
The tilt and rattling of the connector receiver are prevented.
