A plurality of conductor circuits (not shown) by a plurality of conductor pins (91, 92).

The above conductor pins (91, 92) are very small (the diameter is about 0.5 mm and the length is about several mm) due to the small insulating base material 90 on which they are fixed or implanted. And the conductor pins have different shapes.
There are two types of standard pins (A pins) 92 and stand-off pins (B pins) 91. Therefore, in order to fix or implant a large number of such small and different conductor pins on the insulating base material 90, a pin stand jig as shown in FIGS. 12 and 13 is used.

Of the above conductor pins, the standard pin 92 is
As shown in FIGS. 11 and 12, the head 921 and the legs 923
And one brim section 922 provided between them.

On the other hand, as shown in the above figures, the stand-off pin 91 has a head 911, a leg 914, and an upper brim provided between the two.
912 and a lower collar 913. The lower collar 913 is

Plays a role in positioning the electronic component mounting substrate 9 between the two when the electronic component mounting substrate 9 is mounted on a motherboard or the like.

Furthermore, there are various types of electronic component mounting substrates 9 depending on the purpose of use. And standard pin 92,
The number of the stand-off pins 91 and the location of the stand-off pins 91 are all different depending on the type of the electronic component mounting board.

Therefore, the positions where the standard pins 92 and the stand-off pins 91 are arranged on the pin pallet must be accurate.

In the following description, the standard pin is referred to as A
Pins and stand-off pins are called B pins.

 The A pin and the B pin are collectively called conductor pins.

Next, FIG. 12 and FIG. 13 show the A pin 92 and the B pin.
9 shows a pin stand jig 8 for implanting 91. The pin stand 8 has a large number of pin holes on the upper surface side into which the conductor pins are inserted, as shown in FIG. There are two types of pin holes: A pin holes 82, 82... Shown with a small diameter in FIG. 13 and B pin holes 81 shown with a large diameter. The B pin holes 81 are provided at the four corners of the pin stand jig 8 so as to be mounted at the four corners of the substrate (see FIG. 11).
It is provided in the corner.

Further, in FIG. 13, a double-circle preliminary hole 83 which is obliquely orthogonal is a B-pin preliminary hole provided for changing the B-pin position depending on the type of the substrate. In the figure,
The spare hole 83 is used for inserting the A pin, so that the A pin hole 830 is used.
Is fitted. Therefore, the A pin 92 is inserted into the A pin hole 82 and the A pin hole 830 of the preliminary hole 83.

Also, as shown in FIG. 12, the conductor pins are inserted by inserting A-pins 92 and B-pins 91 from above into the A-pin holes 82 and the B-pin holes 81 of the pin stand 8 respectively. Performed by The pin stand 8 is a frame 8 having a through hole 857.
A support plate 853 is superimposed on 54 and a selection plate 851 is further superimposed thereon. These are aligned by the alignment pins 852, and the A pin holes 82, B
The pin hole 81 and the through hole 857 are aligned.

The A pin holes 82 and B pin holes 81 have A pins 92 and B respectively.
The flange 922 and the upper flange 912 of the pin 91 are inserted, and the legs 914 and 923 of both conductor pins are inserted into the through hole 857.

After the conductor pins have been implanted, the electronic component mounting board 9 is pressed downward from above, and the head of the conductor pin is inserted into the through hole.
911 and 921 are fitted together to form a pin grid array as shown in FIG.

Conventionally, as a method of implanting the A pin 92 and the B pin 91 in the pin setting jig 8, a step of inserting the A pin 92 into a predetermined position of the pin setting jig 8 and then setting the B pin 91 to a predetermined position are performed. A missing pin detecting step for checking whether the A pin and the B pin are inserted at predetermined positions,
A missing pin insertion step of inserting a missing A pin or B pin into the missing portion based on the inspection result of the missing pin detection step has been employed.

Conventionally, the pin setting jig 8 into which the A pin 92 is inserted
When inserting the pin 91, as shown in FIG.
B-pin input hoses 88 are respectively arranged above the B-pin holes 81 of the pin setting jig 8, and the hoses 88 are placed from above.
B pin 91 was thrown in. The B pin 91 put into the hose 88 falls therein, and its leg is dropped into the B pin hole 81 of the pin setting jig 8 to be implanted.

Thus, the hose 88 has four B-pin holes 81.
It is arranged above. In the figure, reference numeral 882 denotes a nozzle, and 881 denotes a hose support frame.

Also, in the insufficient insertion step, the lower end of the hose 88 is directed toward the pin hole in which the conductor pin is insufficiently inserted as described above, and the missing A and B pins are inserted into the hose 88. (For example, JP-A-63-57000).

[Problem to be solved]

However, the B pin insertion method and the missing pin insertion method in the above-mentioned conventional method are both based on the insertion of the hose, so that the conductor pins may be clogged in the hose.

In other words, the hose is not necessarily linear between the upper conductor pin insertion position and the lower pin holes 81 and 82, and there are seams and steps between the hoses and between the hose 88 and the nozzle 882 at the tip of the hose. Therefore, the above-mentioned clogging is easily caused. Also,
This also depends on the lightness of the conductor pins themselves.

Further, when the conductor pins are humid or charged with static electricity, the clogging is more likely to occur.

Further, in the above-described conventional method, the nozzle 882 of the hose 88 must be positioned with respect to the B pin hole and the missing pin hole each time the conductor pin is inserted, and the positioning operation is complicated.

As described above, in the conventional method, the insertion of the B pin and the missing pin is uncertain and complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a method and an apparatus for inserting a conductor pin that can reliably and easily insert a B pin and a missing pin into a predetermined position.

[Solutions to solve the problem]

The present invention relates to an A-pin insertion step of inserting an A-pin into a predetermined position of a pin setting jig when inserting two types of conductor pins, an A pin and a B pin, into a predetermined position of a pin setting jig. Insert the B pin into the predetermined position of the vertical jig.
A pin insertion step, an insufficient pin detection step for inspecting whether the A pin and the B pin are inserted into predetermined positions of the pin stand jig, and a shortage based on the inspection result of the insufficient pin detection step. A method of inserting a conductor pin, comprising a step of inserting a pin A or a pin B into a deficient portion thereof. In the B-pin inserting step, only a plurality of B-pins at predetermined positions are sampled from a B-pin jig plate in which a large number of B-pins are aligned, and the B-pins are kept in a positional relationship with each other. Insert the pin holder into the specified position,
In the missing pin inserting step, necessary conductor pins are sampled from a missing pin jig plate provided with a large number of A pins and B pins, and these are sequentially inserted into the corresponding portions of the pin setting jig. There is provided a method for inserting a conductor pin.

The most remarkable point in the present invention is that, in the B-pin insertion step, only a plurality of B-pins at predetermined positions are simultaneously sampled from a B-pin jig plate in which a large number of B-pins are aligned, and these are pinned and set. And inserting necessary conductor pins from the insufficient pin jig plate in the above-mentioned insufficient pin inserting step, and sequentially inserting them into portions corresponding to the insufficient pins of the pin setting jig. .

In the above B pin inserting step, the number of the plurality of B pins is usually four as shown in the above-mentioned conventional method. Note that there may be three or the like depending on the substrate. The following description is based on the case of four B pins.

The B-pin jig plate has a total number of B-pins arranged in a line.
The pin is collected and inserted into a predetermined position of the pin setting jig. In other words, 4 pins having the same positional relationship (predetermined position) as the 4 B pin holes specified in the pin setting jig.
The B pins are simultaneously sampled from the B pin jig plate. Then, the four B pins are transferred onto a pin setting jig while maintaining their positions, and are inserted into B pin holes at predetermined positions of the pin setting jig.

Therefore, the position interval of the B pins sampled on the B pin jig plate is equal to the position interval of the B pins on the pin setting jig.

In addition, the insufficient pin jig plate used in the insufficient pin inserting step has A pins and B pins. Preferably, the two conductor pins are divided into an A pin group and a B pin group. In this case, the A pin and the B pin are not necessarily aligned with the B pin on the B pin jig. Because,
In the missing pin insertion process, the missing conductor pins for the A and B pins are inserted into the missing pin holes, and the arrangement of the conductor pins on the missing pin jig plate and the missing pins on the pin setting jig are used. This is because it has nothing to do with the holes.

The A pin insertion step and the missing pin detection step are, for example,
This is carried out by the method disclosed in JP-A-63-57000.

Next, as an apparatus for carrying out the above method, a pin setting jig for arranging conductor pins, an A pin inserting apparatus for inserting an A pin into a predetermined position of the pin setting jig, and the pin setting jig. Insufficient pin detection for detecting whether or not a conductor pin is inserted in a predetermined position for a B pin insertion device that inserts a B pin into a predetermined position of a jig and a pin stand jig in which an A pin and a B pin are inserted And a missing pin insertion device for inserting a missing A pin or B pin into the pin setting jig according to the conductor pin shortage signal from the missing pin detection device.

The B-pin insertion device picks up only a plurality of B-pins at a predetermined position from a group of B-pins arranged on the B-pin jig plate, and inserts the B-pins while maintaining their positional relationship with each other. It has a B pin insertion machine that inserts it into a predetermined position on the pin setting jig.

In addition, the missing pin insertion device samples the missing pin jig plate prepared with the A pin and the B pin, and the missing conductor pin by the signal from the detecting device, and collects the missing pin on the pin setting jig. And a missing pin insertion machine for sequentially inserting the pins into the parts.

As a means for collecting and inserting the conductor pins used in the B pin insertion machine and the missing pin insertion machine, it is preferable to use a nozzle capable of sucking and discharging the conductor pins. In the suction, the air is sucked from the nozzle onto the prepared conductor pins to collect and suck the conductor pins. In addition, for discharging, the conductive pin sucked as described above is injected by pressurized air toward the insertion hole at a predetermined insertion position of the pin stand jig. Also,
The above-mentioned suction and discharge can be performed by using an electromagnetic force or the like.

(Operation)

In the present invention, in the B-pin inserting step, only a plurality of B-pins at predetermined positions are sampled from the pin jig plate, and are inserted into predetermined positions of the pin setting jig while maintaining their mutual positional relationship. Therefore, the insertion of the B pins is more reliable than the conventional B pin supply and insertion method using a hose, and a plurality of B pins can be inserted at the same time.

In the process of inserting missing pins, a large number of A pins, B pins
Insufficient pins of the A pin or the B pin are sampled from the insufficient pin jig plate where the pins are prepared based on the signal from the insufficient pin detecting step, and are sequentially inserted into portions corresponding to the lack. Therefore, as in the above B pin insertion step, the insertion of the conductor pin is reliably and quickly as compared with the conventional conductor pin supply method.

(Effect)

Therefore, according to the present invention, the insertion of the B pin and the missing pin can be performed automatically, reliably, quickly and easily.
