Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a pin insertion device used for inserting conductor pins for establishing electrical continuity into a board constituting a board for mounting electronic components. It is.

(Prior Art) As a substrate for mounting electronic components, there is a type called a so-called pin grid array, as shown in FIG. 8, for example. This type of board for mounting electronic components is formed by driving a large number of conductor pins (so-called 70 to 200 for one IC chip) into the board that makes up the board to establish continuity. Electronic components such as IC chips on the pin grid array side are mounted on the motherboard by connecting them to another board (called a motherboard) such as a board for mounting electronic components.

There are various types of such conductor pins, and for example, one having a shape as shown in FIG. 9 or FIG. 10. The conductor pin shown in Figure 9 is called a standard pin, and has a head that fits into a hole formed in the board of the electronic component mounting board mentioned above, and a flange that positions the conductor pin with respect to the board. and a support portion that is fitted into the motherboard described above. Further, the conductor pin shown in FIG. 9 is called a standoff pin, and unlike the standard pin described above, it has two flanges. The flange located on the lower side of FIG. 10 is for supporting the board into which these conductor pins are inserted in a predetermined position relative to the motherboard. In any case, these conductor pins have a length of about 5 mm to 10 mm and a pin diameter of
It is very small, about 0.3 mm to 1.0 mm, and is extremely difficult to handle.

Conventionally, in order to attach such conductor pins to the board side, the conductor pins are usually first stored all at once in the holes of a jig, and then placed in a predetermined position according to the holes formed in the jig. Support the array. By pressing the board against this jig, a board for mounting electronic components having conductor pins was formed. Further, most of the types of conductor pins may be the above-mentioned standard pins, and a small number of conductor pins may be the above-mentioned standoff pins.

Conventionally, when it was desired to supply the different types of conductor pins mentioned above, most of them had to be done manually because they were small in number and, as mentioned above, very small. When carrying out such manual work, there are various disadvantages as follows. In other words, handling small conductor pins can be extremely difficult.

If the insertion is checked visually, the operator will be very fatigued.

Therefore, its workability is very poor.

Since the conductor pins 40 are brought into a negative pressure state by the receiving part 31, each conductor pin 40 is supplied to the support jig 50 through each feed pipe 32. That is,
In this feeding device 30, since there is an air flow toward the supporting jig 50 in each feeding pipe 32 due to the suction device 33 disposed below the supporting jig 50, each conductor pin Even if the material 40 is very small and difficult to handle, it is supplied to a predetermined location on the support jig 50 through each feed pipe 32.

As described above, a predetermined number of each conductor pin 40 is automatically supplied into each required insertion hole of the support jig 50, and the electronic component mounting board 60 is inserted from above the support jig 50. By pressing the substrate constituting the substrate, each conductor pin 40 can fit into a predetermined hole such as a through hole in the substrate.
