DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for inserting leads into a multi-lead component on a circuit board.

FIG. 12 shows an example of an electronic / communication device. In the same figure, a shelf 5 is inserted into a frame 4 in which left and right column portions 1 and 1 are joined by an upper and lower connection frames 2 and 3 in an integrated manner, and a shelf 5 is inserted in multiple stages in the up and down direction. 1, 1 are attached and fixed by screws 6. A circuit function is formed by accommodating a large number of printed circuit boards 8 in the shelf 5.

[0003] The shelf 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 number of plug-in type connectors 15 are arranged in parallel on a vertical surface of the inner surface of the shelf 5 and are printed boards. A back board 16 is provided as a circuit board. The circuit board 8 is inserted into the connector 15 of the back board 16 with the upper and lower guides 18 on the inner surface of the shelf 5 serving as guides, and the connector 10 is plugged in and connected.

As shown in a partial perspective view of FIG. 14, the connector 15 of the backboard 16 has a large number of connectors in a width direction in three rows in a width direction inside a connector housing 21 made of a synthetic resin. The contact piece is accommodated therein, and the lead 22 protrudes downward. Mounting seats 24 are formed on the left and right ends, and the mounting holes 2 are formed therein.
5, 25 are provided.

The connector 15 has a large number of long leads 22 projecting in a matrix at predetermined regular intervals in both the width direction and the left-right longitudinal direction.
Is inserted into the through-hole 27 of the back board 16 by soldering or press-fitting so as to be connected to the circuit pattern of the back board 16. Further, screws (not shown) are screwed into the holes 29 and the mounting holes 25 of the backboard 16 to be fixed.

The predetermined spacing between the leads 22 is, for example, 2.54 mm for a normal inch system and 2.5 mm for a millimeter system. The leads 22 protrude from the back surface of the back board 16 and are connected by a so-called wire wrapping method in which a lead wire is wound around the lead several times and connected.

To this end, the leads 22 have a square cross section and are of 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, due to the long length of the leads, the tips do not exactly match the predetermined intervals and are slightly displaced. There are things. For this reason, the insertion work is troublesome and troublesome.

[0008]

2. Description of the Related Art In order to make the ends of the leads 22 of a connector 15 coincide with predetermined intervals and to easily insert the leads into through holes 27 of a circuit board, the present applicant has filed an earlier application, Japanese Patent Application No. 03-07,073.
There is a multi-lead component 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 31 at predetermined intervals, and are formed on the wall surfaces on both sides. Similarly, guide holes 33 are formed at predetermined intervals in this case at three places.

One of the support blocks 3 is inserted into the guide hole 33.
The long, in this case three round pins 36 supported by 5 are inserted. The long round pin 36 is positioned so as to contact the short round pin 32. Thus, a lattice formed by the round pins 32 and 36 is formed in a plan view.

[0011] The lattice spacing is determined by the leads 22 of the connector 15.
Is exactly the same as the predetermined interval. Also, the shape of the gap formed between the matrix lattice pin intervals coincides with the square of the lead 22.

The portions indicated by reference numerals 38, 38 project from the lower surface, and are positioning projections which fit into the holes 29, 29 of the backboard 16 and are fitted. A method of using the lead insertion positioning device 39 will be described with reference to FIG. According to FIG. 16A, the 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 form of a matrix lattice from above, and inserted into this space. Here, even if there is a positional error at the tip due to deformation such as bending of the lead 22, the pins 32 and 36 have a round shape and serve just like a funnel, are easily guided and corrected, and are 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 back board 16. Therefore, when the connector 15 is pushed as shown in FIG.
Since all of them are easily inserted, the long round pin 36 is pulled out from the frame 31 as shown in the figure.

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

[0016]

According to the lead insertion / positioning device described above, the shape of the frame 31 in plan view is the connector 1.
5 and the size of the long round pin 36 is separate. Therefore, the long round pin 36 must be inserted and removed from the guide hole 33 of the frame 31. This insertion work is slightly troublesome and labor-intensive.
For this reason, 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 if adjacent components or members are mounted on the backboard.

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

[0019]

According to the present invention, there is provided a circuit board having a plurality of lead insertion holes formed at a predetermined interval. The lead of a multi-lead component having multiple leads corresponding to the lead is arranged, and a plurality of flat lead alignment members arranged in parallel with each other at a predetermined interval of the multiple leads are interposed between the leads. The leads are rotated to make the flat surface parallel to the circuit board, so that the leads are interposed in adjacent recesses formed at predetermined intervals of the leads formed on the side surfaces of the lead alignment member. By setting the tip of the lead at a predetermined interval position, the lead is guided and inserted into the lead insertion hole of the circuit board in that state, and 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 predetermined intervals into a lead insertion hole of a circuit board, wherein each of the plurality of leads extends around an axis at an interval corresponding to the interval between the leads. A plurality of flat lead aligning members that are rotatably supported and whose short sides have a width that can be inserted and removed between the leads are arranged in parallel, and a shaft of a side surface that is a short side of the flat portion of the lead aligning member A lead insertion / positioning device for a multi-lead component into a circuit board having a recess formed therein for receiving and positioning the leads at intervals corresponding to the intervals of the leads in the direction is applied.

[0021] Then, in the above-mentioned apparatus, means for forming the recess of the lead alignment member into an arc centered on the axis is applied. In addition, the above-described means is used in which both side surfaces of the recess of the lead alignment member are expanded in a trapezoidal shape expanding in the axial direction.

[0022]

According to the gist of the present invention, a flat lead aligning member is interposed between the leads of a multi-lead component, and the lead aligning member is rotated so that the flat surfaces coincide on the same plane. The lead is corrected and positioned so as to be clamped in a recess formed between 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 accordance with the lead insertion hole of the circuit board.

Next, the lead alignment member is rotated so that its flat surface is parallel to the side surface of the lead, so that the lead can be retracted from between the leads. Since the concave portion of the lead alignment member has an arc shape, the contact and detachment from the side surface of the lead due to the rotation can be easily performed.

Further, since both side surfaces of the recess are trapezoidally expanded, even if there is a deviation in the lead position, it can be easily introduced into the center position in the recess.

[0025]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method for inserting leads into a circuit board and the lead insertion positioning device according to the present invention will be described in detail below with reference to the accompanying drawings based on the configuration.

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 portions are denoted by the same reference numerals. In FIG. 1, the connector 15 is positioned on the circuit board 16, and the leads 22 thereof are opposed to the through holes 27, which are lead insertion holes.

(A) As shown in the figure, a flat lead alignment member 41 is placed under the
The connector 15 is disposed in the left-right longitudinal direction of the connector 15 between the two, on a line parallel to the circuit board 16 and with the flat surface facing the side surface of the lead 22. 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 smaller than the lead interval, and the thickness is such that it can be inserted into the gap between the leads 22 with a margin. Therefore,
If the pitch interval between the leads 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 the thickness obtained by subtracting the width of the lead 22 from 2.54 mm.

Next, as shown in FIG. 2B, the lead alignment member 41 is simultaneously rotated 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. 3C, the lead alignment members 41 are formed with recesses 43 for accommodating and positioning the leads 22, respectively, on the left and right. Recesses 43, 4 of adjacent lead alignment members 41, 41
All three positions are formed to coincide.

The recesses 43 are formed in the lead alignment members 41 in a number corresponding to the number of lead rows of the connector 15 so as to correspond to the predetermined intervals of the leads 22 in the length direction thereof. The recess 43 is preferably formed with a margin as large as possible to accommodate the lead 22, and it is inappropriate to provide an extra margin.

The reason is that the position of the lead 22 housed in the space formed by the recess 43 is set at a predetermined position by the recess 43. Even if the position is deviated, the position 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. 2B. When the connector 15 is moved closer 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 the lead 22 as it is. Several meters
m and all lead alignment members 41 are
Rotate as shown. (A) Lead 2 is different from the figure
2 is inserted into the circuit board 16.

In this state, the lead aligning member 41 is retracted in the direction perpendicular to the plane of the paper and is removed from between the connector leads 22. Thereafter, the connector housing 21 is pressed into the circuit board 16 by pushing the connector 15 into the circuit board 16, and both are screwed and fixed.

Since the retreat distance of the lead aligning member 41 is about the width of the connector 15, a space for pulling out a long round pin as in the conventional case is not required. When retreating, the lead alignment member 41 is connected to the connector housing 21.
When lifted and retracted so as to approach the circuit board 1
6 while avoiding adjacent parts.

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

As shown in the plan view of the drawing, a pair of bearing members 59 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 center axis in the figure. This state is a state in which the flat surface of the lead alignment portion 51 is parallel to the paper surface in plan view.

Next, the operating rod 60 is moved horizontally in the direction of the arrow to the left 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 moved horizontally, the pin 61 can move as if it were vertically moved with respect to the oblong hole 55.

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

When the operating rod 60 reciprocates horizontally between the positions shown in FIGS. 5A and 5C, the lead alignment member 50 is rotated about the shaft portion 54, and the lead alignment member 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 members 50 are attached to the leads 22 at predetermined intervals. The arrangement member 50 is configured to be interlocked.

Since it is considered that the operation of the lead alignment member 50 has been understood, the alignment of the leads 22 will be described with reference to FIGS. Figure 1
Regarding the lead arrangement for the rows, the lead alignment member 50
In the figure, only a pair of adjacent lead alignment portions 51, 51 are shown in a plan view.

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

The lead 22-3 is at a predetermined position as apparent from the center line shown, however, the leads 22-1 and 22-
2 is a position slightly shifted from the predetermined position. However, it is located within the range of the expanded taper T.

Then, as shown in FIG. 6, during the horizontal movement of the operating rod 60 described with reference to FIG.
Reference numeral 1 denotes a position just before contact with the lead 22 although it is rotated around its axis and tilted.

Further, as shown in FIG.
When the members 1 and 51 are rotated, the leads 22 are surrounded by the adjacent recesses 57 and 57. Although the lead 22-3 at a predetermined position does not contact the recess 57 of the lead alignment portion 51, the leads 22-1 and 22-2 at the offset position are in contact with the taper T at an angle in the offset direction. Can be

When the lead alignment portions 51, 51 are in a horizontal state as shown in FIG. 8, the leads 22-1, 22-2 at the deviated positions are guided and corrected to predetermined positions by the taper T, so that the recesses 57, 5 are formed.
7 is guided to the bottom. In this way, all the leads 22 are positioned at predetermined positions.

Although the above description has been partially described as a representative, FIG.
And lead 2 for connector 15 described in FIG.
2 applies to all. Therefore, the lead positioned in this manner can be easily inserted into the lead insertion hole 27 of the circuit board 16,
The lead alignment portion can be returned to the vertical state with the tip inserted, and can be easily retracted.

Next, a connector insertion device to which the present invention is applied will be described with reference to FIG. First, FIG.
According to the external perspective view of FIG. 1, an air cylinder 64 is disposed in a connector supply device 63 in which a number of connector storage trays 62 each storing a number of connectors are stacked and stored in parallel. A large number of connector storage trays 62 can be moved to the position of the air cylinder 64, and control is performed so that a desired connector storage tray 62 is set at the position of the air cylinder 64.

A connector insertion device main body 65 is disposed on the side of the connector supply device 63, and a connector insertion robot device 67 is provided above the main body 65. A mounting positioning section 68 for the circuit board 16 is provided 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 the circuit board housing rack 71 conveyed by a circuit board conveyance path (not shown), and are mounted on a lift device 73.

At the tip of the robot device 67, a head 75
Is provided, and can be accurately moved to a predetermined position by controlling the movement of the robot device 67 in the XY directions. The head unit 75 includes an elevating device, and approaches between the connector 15 pushed out by the air cylinder 64 and the mounting positioning unit 68 of the circuit board 16.

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

This operation is repeated, and when many connectors 15 are inserted into the circuit board 16 and the operation is completed, the work is returned to the circuit board accommodation rack 71 and the next circuit board 1 is mounted.
6 is pulled out and the same operation is performed. All of this is automatically performed by a program stored in a control device (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 a perspective view. The lead insertion positioning device 78 includes an operating rod 60 penetrating both side legs 82, 82 in a support frame 81 having a U-shape in plan view, and legs 82, 82.
A bearing member 59 having a U-shape in a plan view is attached to the tip of. A number of lead alignment members 50 are pivotally supported on the longitudinal member 84 of the bearing member 59 in a parallel state.

The lead alignment portion 51 of the lead alignment member 50
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 protected so that they do not spread due to the deflection correcting reaction force of the lead 22.

The hole 55 of the crank arm 53 projecting between the bearing member 59 and the operation rod 60 is
The pins 61 projecting from each other are fitted to each other.
Since the above state is the same as that shown in FIG. 4, refer to FIG. Therefore, the respective symbols are also shown in agreement.

A rack gear 86 is cut into one end of the operating rod 60 and engaged with the operating rod 60 in order to reciprocate the operating rod 60, tilt the crank arm 53, and position the lead alignment portion 51 between the horizontal state and the vertical state. The pinion gear 87 is arranged. The lead alignment portion 51 repeats the above posture by reciprocating the pinion gear 87 by a predetermined angle.

FIG. 11 is a schematic side view showing a state in which the lead insertion / positioning device 78 is attached to the head section 75 in FIG. A screw shaft 90 for moving the head unit 75 in the left-right direction of the paper plane, that is, the X-axis direction, and a screw shaft 92 for moving the lead insertion / positioning device 78 toward and away from the connector chuck 91 therebelow. Reference numeral 93 denotes an air cylinder for moving the connector chuck 92 up and down, and reference numeral 95 denotes an air cylinder for moving the lead insertion positioning device 78 up and down.

The Y-axis drive system for moving the head unit 75 in a direction perpendicular to the paper surface is not shown. Although a guide is provided so as not to swing around the screw axis, it is also not shown.

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

With the above configuration, referring to FIGS. 1 to 10, the connector 15 is held by the connector check 91 and is moved in the X and Y directions to be set at a predetermined position on the circuit board 16. Next, the screw shaft 92 is rotated to bring the lead insertion / positioning device 78 closer to the connector 15, and
The lead alignment portion 51 is set in a vertical state and positioned in the lead 22. The lead alignment portion 51 is rotated to align the leads 22, and the air cylinders 93 and 95 are operated to be inserted into the lead insertion holes 27 of the circuit board 16.

Thereafter, the lead insertion positioning device 78 is retracted with the lead alignment portion 51 in a vertical state, and the connector check 91 is further pushed down to completely insert the lead 22. In this manner, 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 types can be considered within the scope of the configuration. For example, since the rotation of the lead alignment member may be changed between the horizontal state and the vertical state, it is not a crank arm but, for example, a pitch circle diameter of 2.54 mm.
By forming a spur gear of the above type and forming a gear train with the adjacent lead alignment members, the same posture can be obtained in a mutually reversed relationship.

The lead insertion positioning device is not limited to being combined with the connector automatic insertion device of the preferred form as described above, but may be applied to manual operation. Also,
The free end of the lead alignment member, which is not supported, can be supported on a suitable detachable bearing, whereby a stable state can be obtained.

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

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

[0072]

As described above in detail, according to the present invention, the lead alignment member is inserted from the short side of the connector, and the lead alignment member is rotated to be in a horizontal position, thereby 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 alignment member can be set in a vertical posture and retracted by only retracting almost the distance of the short side of the connector. Requires less space on top.

Since the recess of the lead aligning member is a circular arc centered on the axis, the lead can easily and smoothly approach and leave the side surface. Since the side wall of the recess of the lead alignment member is expanded in a trapezoidal shape expanding in the axial direction, the deviated lead can be easily introduced into a predetermined position.

The lead alignment member according to the present invention has good manufacturability of the lead alignment member itself because only one type of lead alignment member is arranged in parallel. Such a single type of lead alignment member enables a large number of leads to be collectively positioned and aligned in the X-Y directions, and furthermore, the insertion and removal from one side of the lead component, and the operability is improved. Since it is good, it is efficient and the time for lead insertion work is extremely reduced.

Although the lead alignment portion of the lead alignment member is shown in the shape of a flat plate, the insertion and removal of the lead alignment member are further facilitated by making the cross section elliptical. As described above, according to the present invention, various effects are obtained, so that the present invention can be applied to the insertion of a multi-lead component into a circuit board, and the practical effect is remarkable.
