Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lead insertion method and a lead insertion positioning device for a multi-lead component on a circuit board.

FIG. 12 shows an example of an electronic / communication device. In the figure, the column parts 1 and 1 on both the left and right sides are joined by the upper and lower connecting frames 2 and 3 to be integrated, and the shelves 5 are inserted in the vertical direction inside the frame frame 4 in multiple stages to form the left and right column parts. It is attached and fixed to screws 1 and 1 with screws 6. A large number of printed circuit boards 8 are housed in the shelves 5 to form a circuit function.

The shell 5 is shown in the perspective view of FIG. 13 with the left side plate removed. A plug-in type connector 10 is attached to the insertion-side end of the circuit board 8 to be accommodated, and a large number of plug-in type connectors 15 are arranged in parallel on the vertical surface of the inner surface of the shell 5 to form a printed board. A back board 16 as a circuit board is provided, and the circuit board 8 is inserted into the connector 15 of the back board 16 by using the upper and lower guides 18 on the inner surface of the shelves 5 as guides, and the connector 10 is plugged in and connected.

As shown in the partial perspective view of FIG. 14, the connector 15 of the backboard 16 has three rows in the width direction and a large number in the length direction in the left and right direction inside a connector housing 21 made of a synthetic resin molded product. The contact piece is housed, and the lead 22 thereof is projected downward, and mounting seats 24, 24 are formed at the left and right ends, and the mounting hole 2 is formed therein.
5, 25 are provided.

The connector 15 has a number of long leads 22 projecting in a matrix at predetermined equal intervals in both the width direction and the left-right longitudinal direction.
Is inserted into the through hole 27 of the backboard 16 and is soldered or press-fitted to be connected to the circuit pattern of the backboard 16. In addition, screws (not shown) are passed through the holes 29 and the mounting holes 25 of the backboard 16 so as to be fastened and fixed.

The predetermined interval between the leads 22 is, for example, 2.54 mm for an ordinary inch system and 2.5 mm for a millimeter system. The lead 22 is projected on the back surface of the backboard 16 and is wire-connected by a so-called wire wrapping method in which a lead wire is wound several times to connect the wire.

For this reason, the lead 22 has a square cross section and is also a considerable length. From the above, the leads 22 of the connector 15 are inserted into the through holes 27 of the backboard 16 in alignment with each other. However, since the lead length is long, the tips thereof are not exactly aligned with the predetermined interval and are slightly displaced. There are things to do. Therefore, the insertion work is troublesome and troublesome.

[0008]

2. Description of the Related Art In order to make the ends of leads 22 of a connector 15 coincident with each other at a predetermined interval and easily inserted into a through hole 27 of a circuit board, the applicant of the present application filed Japanese Patent Application No. 03-07.
There is a multi-lead insertion aid as a lead insertion positioning device filed in 1991.

According to this, as shown in the perspective view of FIG. 15, a large number of short round pins 32 having a small diameter are projected from the inside of the bottom surface of the U-shaped frame body 31 at predetermined intervals and the wall surfaces on both sides are formed. Again, at predetermined intervals, in this case, the guide holes 33 are formed at three places.

One support block 3 is provided in the guide hole 33.
The long, in this case three round pins 36 supported by 5 are inserted. The long round pin 36 is located in contact with the short round pin 32. As a result, a lattice formed by the round pins 32 and 36 is formed in a plan view.

This lattice spacing is determined by the leads 22 of the connector 15.
It exactly matches the predetermined interval of. In addition, the shape of the gap formed between the pin intervals in the matrix lattice shape coincides with the square of the lead 22.

The portions denoted by reference numerals 38 and 38 are positioning projections which are projected on the lower surface and are fitted in holes 29, 29 of the backboard 16 so as to fit therein. A method of using the lead insertion positioning device 39 will be described with reference to FIG. According to FIG. 16 (a), the present device 39 is placed on the backboard 16 and the protrusion 38 is fitted into the hole 29 to set the position. The long pin 36 is inserted into the guide hole 33.

In this state, as shown in FIG. 3B, the lead 22 of the connector 15 is brought close to the space between the pins 32 and 36 in the matrix lattice form from above and inserted into this space. Even if there is a position error at the tip due to deformation such as bending of the lead 22, the pins 32 and 36 have a round shape, just play a role of a funnel, and are easily guide-corrected and inserted between them. That is, the tip of the lead is set at a predetermined position.

In this state, the tip of the lead 22 is no longer the same as the through hole 27 of the backboard 16. Therefore, when the connector 15 is pushed as shown in FIG.
Since everything is easily inserted into the frame, the long round pin 36 is pulled out from the frame 31 as shown in the figure.

Then, as shown in the side view of FIG. 3D, the frame body 31 is slightly lifted to remove the projection 38 from the hole 29, and the frame body 31 is removed from the backboard 16 so that the connector 15 is formed.
Also evacuate. Then, the connector 15 is completely pushed into the backboard 16 as shown in FIG.
Are projected on the back surface of the backboard 16 and fixed by screws through the holes 25 and 29.

[0016]

According to the above lead insertion and positioning device, the shape of the frame 31 in plan view is the connector 1.
The size of the long round pin 36 is almost the same as that of No. 5 and is a separate body. Therefore, the long round pin 36 must be inserted into and removed from the guide hole 33 of the frame 31. This insertion work is a little troublesome and requires a lot of manpower.
Therefore, there is a problem that automation by a robot is difficult.

Since the length of the long round pin 36 corresponds to the length in the left-right longitudinal direction of the connector, a space is required in the pulling-out direction to pull it out of the frame 31. This has a problem that the present apparatus cannot be applied when adjacent components or members are mounted on the backboard.

It is an object of the present invention to solve the above conventional problems.

[0019]

Means for Solving the Problems According to the present invention for solving the above-mentioned problems, a gap between the lead insertion holes is provided with respect to the lead insertion holes of a circuit board having a large number of lead insertion holes formed at predetermined intervals. The leads of a multi-lead component having multiple leads aligned with each other are opposed to each other, and a plurality of flat lead alignment members arranged in parallel in parallel with each other at a predetermined interval of the multiple leads are interposed between the leads. By rotating the flat surface so that the flat surface is in parallel with the circuit board, the leads are respectively interposed in adjacent recesses formed corresponding to predetermined intervals of the leads formed on the side surfaces of the lead alignment member. The lead tips are set at predetermined intervals by this, the leads are guided and inserted into the lead insertion holes of the circuit board in that state, and then the lead alignment member is flattened with respect to the circuit board. Lead insertion method of a multi-leaded component to the circuit board so as to insert the leads of a multi-lead component to the circuit board by retracting rotated in the straight direction.

A lead insertion device for guiding and inserting a multi-lead component having a large number of leads at a predetermined interval into a lead insertion hole of a circuit board, each of which is arranged around an axis at intervals corresponding to the interval of the leads. It has a large number of flat lead alignment members which are rotatably supported and whose short sides have a width that allows insertion and removal between the leads, and the axis of the side face which is the short side of the flat portion of the lead alignment members. A lead insertion / positioning device for a multi-lead component is applied to a circuit board in which recesses for accommodating and positioning the leads are formed at intervals corresponding to the intervals of the leads in the direction.

Thus, in the above device, the recess of the lead alignment member is formed in a circular arc centered on the axis. Further, the above-mentioned means for expanding both sides of the recess of the lead aligning member into a trapezoidal shape that expands in the axial direction is applied.

[0022]

According to the above-mentioned gist of the present invention, the flat lead aligning member is interposed between the leads of the multi-lead component, and the lead aligning member is rotated so that the flat planes coincide with each other. The leads are straightened and positioned so as to be sandwiched in the recesses formed between the adjacent lead alignment members. As a result, the position of the tip of the lead is set at a predetermined position, so that the lead can be easily inserted in alignment with the lead insertion hole of the circuit board.

Then, by rotating the lead aligning member so that its flat surface is parallel to the side surface of the lead, the lead aligning member can be retracted from between the leads. Since the recess of the lead aligning member is arcuate, it can be reasonably contacted / disengaged with the side surface of the lead due to the rotation.

Further, since both side surfaces of the recess are expanded in a trapezoidal shape, even if the lead position is deviated, it can be easily guided to the central position in the recess.

[0025]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A lead insertion method and a lead insertion positioning device for a multi-lead component on a circuit board according to the present invention will be described in detail below with reference to the drawings in specific embodiments based on the outline of the structure.

FIG. 1 shows an embodiment of the present invention. The connector 15 and the circuit board 16 are the same as those described in FIG. Therefore, the same parts are designated by the same reference numerals. In FIG. 1, the connector 15 is positioned on the circuit board 16, and its leads 22 are opposed to the through holes 27 which are lead insertion holes.

As shown in FIG. 3A, a flat lead aligning member 41 is provided below the lead 22 on both outer sides of each lead 2.
They are arranged between the two in parallel with the circuit board 16 and with the flat surfaces facing the side surfaces of the leads 22 in the longitudinal direction of the connector 15. That is, the flat surface is perpendicular to the circuit board 16. Although not shown, the lead alignment members 41 are all connected so as to be interlocked.

The width of the flat surface of the lead alignment member 41 is equal to or slightly narrower than the lead interval, and the thickness is a thickness that can be inserted into the gap between the leads 22 with a margin. Therefore,
If the lead pitch interval is 2.54 mm, the width is equal to or slightly smaller than 2.54 mm, and the thickness is set to be equal to or less than 2.54 mm minus the width of the lead 22.

Next, as shown in FIG. 6B, the lead aligning members 41 are rotated together so that the flat surface is parallel to the circuit board 16. This is possible because, as shown in the partial plan view of FIG. 7C, the lead aligning member 41 is formed with the recesses 43 on the left and right for accommodating and positioning the leads 22, respectively. , The recesses 43, 4 of the adjacent lead alignment members 41, 41
The positions of 3 are formed so as to coincide with each other.

The recesses 43 are formed in each of the lead alignment members 41 in the lengthwise direction so as to match the predetermined intervals of the leads 22 and the number of lead rows of the connector 15. The recess 43 is preferably formed with a margin that can accommodate the lead 22, and it is inappropriate to provide an extra margin.

The reason for this is that the lead 22 accommodated in the space formed by the recess 43 is set at a predetermined position by the recess 43. Even if the position is biased, it is corrected and set to a predetermined position by the recess 43.

As described above, the positions of all the leads 22 are set to predetermined positions in the state shown in FIG. 3B, and when the connector 15 is brought close to the circuit board 16 in this state, the leads 22 face the lead insertion holes 27. Therefore, the lead 22 can be inserted into the insertion hole 27 by pressing as it is. A few meters
All lead alignment members 41 in the state of being inserted about m (a)
Rotate as shown. (A) Lead 2 is different from the figure
That is, the tip of No. 2 is inserted in the circuit board 16.

In this state, the lead alignment member 41 is retracted in the direction orthogonal to the paper surface and removed from between the connector leads 22. After that, the connector 15 is pushed into the circuit board 16 to bring the connector housing 21 into close contact with the circuit board 16 and fix them by screwing.

Since the retracting distance of the lead aligning member 41 is about the width of the connector 15, there is no need for a space for pulling out a long round pin as in the conventional case. When retracting, the lead alignment member 41 is attached to the connector housing 21.
Circuit board 1
6 Can be performed while avoiding adjacent parts.

Since the lead alignment members 41 are connected so that they are all interlocked with each other, there is no separated portion. A more specific embodiment of the present invention will be described in detail with reference to FIG.

FIG. 2A is a plan view of the lead alignment member 50 when a flat surface is visible, FIG. 2B is a plan view when the thickness is visible, and FIG. 2C is a view C of FIG. -C shows a side view of the arrow view.

In each drawing, the lead alignment member 50 includes a flat lead alignment portion 51 and an end crank arm 5.
3 and a shaft portion 54 therebetween. The crank arm 53 is formed with an oval hole 55 coinciding with the axial direction, and has an inclination of an angle K (45 °) with the flat surface. Recesses 57 are formed at intervals P on both sides of the lead alignment portion 51, and the interval P of the recesses 57 is a predetermined interval of the leads 22 of the connector 15, for example, 2.54 mm or
Equal to 2.5 mm. The width H of the flat surface has the same dimension or a dimension slightly narrower than that.

Details of the recess 57 are shown in FIGS. 3 (a) and 3 (b), which correspond to FIGS. 2 (a) and 2 (b). As shown in this partial detail view, the recess 57
Both side surfaces of the are expanded into a trapezoidal taper T that expands in the axial direction.

A recess 57 in the lead alignment portion 51 of FIG.
The AA cross section of the portion is as shown in FIG.
Both the outer shape and the bottom surface of the recess 57 are formed in an arc shape centered on the axis. This is formed by forming a portion of the columnar shape which should be the recess 57 into a tapered groove, and scraping both sides of the columnar shape to form a flat surface.

As shown in FIG. 3D, the BB cross section of the shaft portion 54 in FIG. 2 is formed in a circular shape and has a diameter smaller than the outer shape of the lead alignment portion 51 and smaller than the width of the flat portion. It has a large diameter. The lead aligning member 50 is preferably made of hard, high-strength material such as tool steel that has been heat-treated and polished.

Rotating the lead alignment member 50 of FIG. 2 will be described with reference to FIG. FIG. 4B
As shown in the plan view of the figure, a pair of bearing members 59 each having a semicircular bearing hole 58 formed in the shaft portion 54 are combined from above and below to support the shaft portion 54. The pin 61 of the operating rod 60 is inserted into the hole 55 of the crank arm 53.
As shown in the side view of FIG. 4A, the crank arm 53 is stably maintained at a position of 45 ° to the right of the central axis in the drawing. In this state, the flat surface of the lead alignment portion 51 is parallel to the paper surface in plan view.

Next, the operating rod 60 is horizontally moved in the arrow direction to the left side in the figure. This state is shown in FIG. The crank arm 53 moves in an arc with the movement,
Since the pin 61 is horizontally moved, the pin 61 can move with respect to the elliptical hole 55 as if it moves up and down.

The crank arm 53 is moved 90 ° to the left side in the figure to a position 45 ° from the center. As a result, the flat surface of the lead alignment portion 51 becomes orthogonal to the paper surface in plan view as shown in FIG.

When the operating rod 60 horizontally reciprocates between the positions shown in FIGS. (A) and (c), the lead alignment member 50 is rotated around the shaft portion 54, and the lead alignment portion 51 is rotated.
The posture is alternately changed between the horizontal state and the vertical state.

The bearing member 59 and the operating rod 60 have a length corresponding to the length of the connector 15, and the lead aligning member 50 is attached to each of the leads 22 at a predetermined interval. The alignment member 50 is configured to be interlocked.

Since it is believed that the operation of the lead alignment member 50 is understood above, the alignment of the leads 22 will be described with reference to FIG. 5 and subsequent figures. The figure is 1
Regarding the lead arrangement for the rows, the lead alignment member 50
Only a pair of adjacent lead alignment portions 51, 51 are shown in plan view.

First, referring to FIG. 5, as shown in a plan view (a) and a side view (b), the lead alignment portions 51, 51 of the lead alignment member 50 are vertically inserted into both sides of the lead 22. It At this time, the recess 57 is positioned so as to correspond to the lead 22.

Leads 22-3 are in place, as is apparent from the centerline shown, but 22-1 and 22-
2 is a position slightly deviated from the predetermined position. However, it is located within the range of the expanded taper T.

Next, as shown in FIG. 6, in the process of horizontally moving the operating rod 60 explained in FIG.
Reference numeral 1 indicates a position immediately before contacting the lead 22 although it rotates about its axis and tilts.

Further, as shown in FIG. 7, the lead alignment portion 5
When 1 and 51 are rotated, the lead 22 is surrounded by the adjacent recesses 57 and 57. The lead 22-3 at a predetermined position does not come into contact with the recess 57 of the lead alignment portion 51, but the leads 22-1 and 22-2 at the eccentric position are in a state where the angle in the eccentric direction comes into contact with the taper T portion. Be done.

When the lead alignment parts 51, 51 are in the horizontal state in FIG. 8, the leads 22-1, 22-2 in the eccentric position are guided and corrected to predetermined positions by the taper T, and the recesses 57, 5 are formed.
You will be guided to the bottom of 7. In this way, all leads 22 are positioned in place.

Although the above description has been partially explained as a representative, FIG.
And the lead 2 for the connector 15 described in FIG.
It applies to all two. Therefore, the lead thus positioned can be easily inserted into the lead insertion hole 27 of the circuit board 16,
It is possible to return the lead alignment portion to the vertical state with the tip inserted and to easily retract it.

Next, a connector insertion device to which the present invention is applied will be described with reference to FIGS. First, FIG.
According to the external perspective view of 1., an air cylinder 64 is arranged in the connector supply device 63 in which a large number of connector accommodating trays 62 accommodating a large number of connectors are stacked and accommodated in parallel. A large number of connector accommodating trays 62 can be moved to the position of the air cylinder 64, and a desired connector accommodating tray 62 is controlled to be set at the position of the air cylinder 64.

A main body 65 of the connector insertion device is arranged on the side surface of the connector supply device 63, and a connector insertion robot device 67 is provided on the upper part of the main body 65. Further, there is a mounting positioning portion 68 for the circuit board 16 on the lower surface of the movable range of the robot device 67.

A large number of circuit boards 16 are stacked and housed in a circuit board housing rack 71 that has been carried by a circuit board carrying path (not shown), and is mounted on a lift device 73.

A head portion 75 is provided at the tip of the robot device 67.
Are provided and can be accurately moved to a predetermined position by the movement control of the robot device 67 in the XY directions. Further, the head portion 75 has an elevating device and is brought close to between the connector 15 pushed by the air cylinder 64 and the mounting positioning portion 68 of the circuit board 16.

With the above configuration, when the circuit board 16 pulled out from the circuit board accommodating rack 71 is mounted and installed on the mounting positioning section 68, the robot device 67 causes the air cylinder 64 to move.
The connector 15 of the connector accommodating tray 62 pushed out by is taken out by the head portion 75, carried to a predetermined position of the circuit board 16 installed, and the leads 22 are inserted into the lead insertion holes 27.

When this work is repeated and a large number of connectors 15 are inserted into the circuit board 16 and the work is completed, the connector is returned to the circuit board accommodating rack 71 and the next circuit board 1 is inserted.
Pull out 6 to perform the same work. All of this is automatically performed by a program stored in a controller (not shown).

Here, a lead insertion positioning device applied to the head portion 75 of this connector insertion device is shown in FIG.
0 will be described with reference to the perspective view. This lead insertion positioning device 78 includes an operating rod 60 that penetrates both side leg portions 82, 82 in a support frame 81 having a U-shape in plan view, and leg portions 82, 82.
A bearing member 59 having a U-shape in plan view is attached to the tip of the. A large number of lead alignment members 50 are axially supported in parallel with each other on the longitudinal member 84 of the bearing member 59.

The lead alignment portion 51 of the lead alignment member 50.
Both ends of the bearing are set so as to be in contact with the inner surfaces of the legs of the bearing member 59 in a horizontal state, and are carefully protected so as not to spread due to the deviation correcting reaction force of the lead 22.

In the hole 55 of the crank arm 53 protruding between the bearing member 59 and the operating rod 60, the operating rod 60 is inserted.
The pins 61 projecting from each other are fitted into each other.
The above state is similar to that shown in FIG. 4, so refer to FIG. Therefore, the respective symbols are also shown in agreement.

In order to reciprocate the operating rod 60 to tilt the crank arm 53 and position the lead alignment portion 51 in the horizontal state and the vertical state, a rack gear 86 is cut at one end of the operating rod 60 and meshes with the rack gear 86. The pinion gear 87 is arranged. By rotating the pinion gear 87 back and forth by a predetermined angle, the lead alignment portion 51 repeats the above posture.

FIG. 11 is a schematic side view showing a state where the lead insertion positioning device 78 is attached to the head portion 75 of FIG. It is composed of a screw shaft 90 for moving the head portion 75 in the left-right direction of the paper surface, that is, the X-axis direction, and a screw shaft 92 for moving the lead insertion positioning device 78 closer to the connector chuck 91 thereunder. Reference numeral 93 is an air cylinder for moving the connector chuck 92 up and down, and 95 is an air cylinder for moving the lead insertion positioning device 78 up and down.

A Y-axis drive system for moving the head portion 75 in a direction orthogonal to the paper surface is not shown. Further, although it has a guide so as not to swing around the screw axis, it is also omitted in the drawing.

Further, the screw shaft 92 and the lead alignment device 78 move in the same relationship with respect to the connector chuck 91 which is moved by the rotation of the screw 90, and the lead insertion positioning device 78 is independently moved by the rotation of the screw shaft 92. It is configured so as to be able to get close to the chuck 91.

With the above structure, referring to FIGS. 1 to 10, the connector 15 is held by the connector jack 91 and moved in the XY directions to set the connector 15 at a predetermined position on the circuit board 16. Then, the screw shaft 92 is rotated to bring the lead insertion positioning device 78 close to the connector 15, and
The lead alignment portion 51 is placed in the lead 22 in a vertical state. The lead alignment portion 51 is rotated to align the leads 22, and the air cylinders 93 and 95 are operated to insert the leads 22 into the lead insertion holes 27 of the circuit board 16.

After that, the lead alignment portion 51 is set in the vertical state, the lead insertion positioning device 78 is retracted, the connector chuck 91 is further pushed down, and the lead 22 is completely inserted. In this way, the work of attaching the connector 15 can be continued.

Although the present invention is as described above, the present invention is not limited to the embodiments, and various kinds can be considered within the scope of the constitution. For example, since the rotation of the lead alignment member may be changed between the horizontal state and the vertical state, the pitch circle diameter may be 2.54 mm instead of the crank arm.
By forming the spur gears of the above and forming a gear train with the adjacent lead aligning members, it is possible to have the same posture in a mutually reversed relationship.

The lead insertion / positioning device is not limited to being combined with the preferable connector automatic insertion device as described above, but may be applied to manual operation. Also,
It is also possible to rotatably support the free end of the lead alignment member which is not rotatably supported by a suitable detachable bearing, and by doing so, a stable state can be obtained.

Further, it goes without saying that the circuit board is not limited to the backboard of the printed board, but can be applied to any circuit board. The lead aligning member of the present invention is most preferably positioned near the tip of the lead. However, when the deviation of the lead is large and the deviation amount is larger than the taper T, the lead is placed horizontally near the connector housing in the recess. In this state, the tip can be moved to a predetermined position by moving it near the tip of the lead.

Further, since it can be applied to other parts having multiple leads at predetermined intervals, it is not limited to the connector.

[0072]

As described above in detail, according to the present invention, the lead aligning member is inserted from the short side of the connector, and the lead aligning member is rotated to be in the horizontal posture, so that the lead aligning member can be easily and surely. The position of the lead tip can be set to a predetermined position, and after insertion into the circuit board, the lead aligning member can be retracted by keeping the lead posture in a vertical posture and by retracting substantially the short side of the connector. It takes up little space on the top.

Since the recess of the lead alignment member is an arc centered on the axis, the lead can be smoothly approached to and separated from the side surface of the lead. Since the side wall of the recess of the lead alignment member is expanded into a trapezoidal shape that expands in the axial direction, the deviated lead can be easily introduced into a predetermined position.

The lead aligning member of the present invention has a good manufacturability of the lead aligning member itself because a large number of one kind are arranged in parallel. With such one type of lead aligning member, it is possible to position and align a large number of leads collectively in the XY direction. Because it is good, it is efficient and the lead insertion time is extremely shortened.

Although the lead aligning portion of the lead aligning member is illustrated as a flat plate shape, the lead aligning member has an elliptical cross section to facilitate insertion and removal. As described above, according to the present invention, since it has various effects, it is extremely effective when applied to lead insertion of multi-lead components on a circuit board.
