The NC moving table 10 is positioned so that the connector 1 in the sucked state and the connector press-fitting position on the printed circuit board 8 coincide.

A pressure receiving turret 12 is provided on the lower surface side of the NC moving table 10. The rotary table 12a of the pressure receiving turret 12 has a plurality of push rods 12b
1 to 12b-N are elastically held. Pressure receiving heads 12d-1 to 12d-N that match the shape and pin arrangement of the connector 1 are attached to the upper end of each push rod 12b. Each pressure receiving head 12d is formed with a punch hole into which the lower end of the pin of the connector 1 is inserted. The rotary table 12a is rotated to a command position by the drive motor 12c, the pressure receiving block 13a of the pressure receiving unit 13 is raised, and a predetermined push rod 12b is pushed up. The pressure receiving block 13 is a cylinder 13
b and is guided by the guide 13c and the guide shaft 13d.

According to the above configuration, the predetermined press-fit head 11
d denotes the press-fit head 1 in a state where the connector 1 is sucked and held.
While lowering 1d, the pressure receiving section 13 raises a predetermined pressure receiving head 12d, and while the press-fit head 11d and the pressure receiving head 12d hold the connector 1 with the printed circuit board 8 interposed, the pressure receiving section 13 Press the connector 1 into the mounting position.

In the connector press-fitting device shown in FIG. 5, a stocker for housing the connector 1 and a station for press-fitting can be separated. In general, the operation shown in FIG. 5 is such that the connector 1 is transported from the stocker, transferred to the station, and press-fitted into the printed circuit board.

That is, the apparatus shown in FIG. 5 has the following advantages when the number of connectors is large. The first advantage is that the cycle time as a whole can be shortened because control can be performed independently for each station. The second advantage is that the storage capacity of the connector can be easily changed because the stocker is independent. A third advantage is that the connector can be added even during the press-fitting operation depending on the structure of the stocker.

However, when the amount of connectors is small,
The advantages of the apparatus of FIG. 5 have the following problems. First, a large installation area is required for the entire apparatus. Secondly, since the stocker and each transport mechanism are required, the entire apparatus becomes expensive. Thirdly, since there are many stations, there is a possibility that the frequency of failures during the connector delivery operation may increase.
