By the way, this type of connector press-fitting device is provided with a plurality of types of connectors 1-1 to 1-N.
In particular, the above-mentioned is capable of dealing with four types of connectors. In this device, the press-fitting heads 11d-1 to 11d-1 dedicated to each type of connector are provided.
1d-N, pressure receiving head 12d-12d-N, tray 6-
An operator may mistakenly attach the attachments 1 to 6-4. In this case, a mistake may be detected during automatic operation and automatically stopped before being press-fitted onto the printed circuit board to warn the operator.

For example, the type of the connector 1 is completely different,
If the number of pins and pin pitch are different, press-fit head 11
If any one of the pressure d, the pressure receiving head 12d, and the tray 6 is mistaken, it cannot be adsorbed and held by the press fitting head 11d and a warning is given, or the through hole of the printed board 8 or the connector pin of the pressure receiving head 12d is inserted. It will not warn you, so you will not press it. But,
As shown in (A) and (A) of FIG. 8, the pin pitches (a, b) and the pin arrangement (4 rows) of the connector are the same, and there is no great difference in the number of pins (only the A part and the B part have the connector 1). -1 has more pins) 2 types of connectors 1-1, 1-
If the attachment No. 2 is mistaken, it may be pressed into the printed circuit board 8.

This occurs when the press-fitting head is originally inserted by mistake for the connector 1-1 of (a) when the connector 1-1 of (a) is press-fitted. That is, since the press-fitting head 11d is held by adsorbing the connector pins, the press-fitting head 11 dedicated to the connector (a) is used.
When the connector 1-1 of (a) is adsorbed by d-2, it can be held when there is no large difference in the number of pins, and the pressure receiving head 12d is definitely the original (a) connector. Since the dedicated pressure receiving head 12d-1 is attached and the printed circuit board 8 also has a through hole for the connector of (a), the connector 1-1 is inserted into the printed circuit board 8 and the pressure receiving head 12d and press-fitted. I will end up. In this case, when the press-fitting operation is performed, the press-fitting head 11d does not push the portions A and B of the connector 1-1 of (a), and therefore, as shown in FIG.
Only the pin of the part is not pressed and floats.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a connector press-fitting device with a check function for attachment of the present invention will be described below. In addition, the same reference numerals are given to the same configurations and structural parts as those of the above-described conventional technique, and the description thereof will be omitted. The operation of sequentially press-fitting the connector 1 into the printed circuit board 8 during the automatic operation is the same as that of the conventional press-fitting device. As shown in FIGS. 1 and 2, a check hole 64 is formed in the tray 6 used in the press-fitting device of this embodiment. The check hole 64 is formed in the press-fitting head 11d corresponding to the connector 1 placed on the tray 6.
Has a dimension such that the tip of the can not be inserted.

This size will be described with reference to FIGS.
In FIG. 2, the tray 6 is the connector 1 of FIG.
-1 dedicated tray. The area of the tip portion of the press-fitting head 11d-1 that holds the connector 1-1 by suction is (C2-
α) × (d−α). α is a clearance between the inner wall of the connector housing and the press-fitting head. On the other hand, the size of the check hole 64 of the tray 6, e, f is e
<(C2-α), f> (d-α). Also,
Connector (a) of FIG. 8 similar to connector 1-1

In contrast, the dimensions e and f of the check hole 64 of the tray 6 are e> (c1−α) and f> (d−).
α).

That is, when press-fitting the connector 1-1,
When the operator mistakenly attaches the press-fitting head 11d and attaches the press-fitting head 11d-2 for the connector 1-2 of FIG. 8A, the press-fitting head 11d-2 is inserted into the check hole 64 of the tray 6. When the insertion operation is performed, the dimensions (c1-α) and (d-α) of the press-fitting head 11d-2 are smaller than the dimensions (e, f) of the check hole 64, so that the insertion can be performed. However, without a mistake, the connector 1- of FIG.
If the press-fitting head 11d-1 for No. 1 is attached, the dimensions (c2-α) and (d-α) of the press-fitting head 11d-1 are (c2-α) with respect to the dimensions (e, f) of the check hole 64. Is e
Since it is larger, it cannot be inserted as shown in FIG. Therefore, it is possible to confirm the press-fitting head 11d with respect to the tray 6 as NG when the insertion is possible and OK when the insertion is not possible.

Next, the connector press-fitting operation by the connector press-fitting device using the tray 6 having the check hole 64 will be described. When the connector 1 of the tray 6 is positioned below the press-fitting head 11d during automatic operation, and the connector 1 (tray 6) is the first type of connector to be used during automatic operation, the tray is below the press-fitting head 11d. The check holes 64 of 6 are positioned, and the press-fitting head 11d is lowered. Here, when the press-fitting head 11d contacts the tray 6 and does not enter the check hole 64, the tray 6
The press-fitting head 11d determines that they are compatible and raises the press-fitting head 11d, and the automatic driving operation according to the prior art is performed from the transfer operation of the connector 1 of the tray 6 to the press-fitting operation. When another connector is used for the first time during this automatic operation, the check operation is also performed in the tray 6 by the check hole 64 to confirm the correspondence with the press-fitting head 11d.

As described above, according to the connector press-fitting device with the attachment check function of this embodiment,
The tray 6 is provided with a check hole 64 for confirming the size of the press-fitting head 11d so that the press-fitting head 11d can be automatically operated.
Before the first connector 1 placed on the tray 6 is received by the NC moving table 10, the check hole 64 of the tray 6 is positioned, the press-fitting head 11d is lowered, and the press-fitting head 11d is placed inside the check hole 64. Since it is possible to confirm the correspondence between the connector 1 placed on the tray 6 and the press-fitting head 11d depending on whether or not the connector is inserted,
It is possible to prevent inconveniences such as press-fitting the wrong type of connector 1 and eliminate the occurrence of defective products. That is, different types of connectors 1 can be correctly press-fitted into the printed circuit board 8 and the productivity can be greatly improved. Further, since the check holes 64 are simply formed in the tray 6, the cost is hardly increased by adding the check function, which is economical.

The check hole 64 in this embodiment is
In the actual connector, only the e dimension having many patterns is checked, but it is also possible to perform only the f dimension or both the e and f dimensions.

[0021]

As described above, according to the connector press-fitting device with the attachment check function of the present invention,
The following effects can be obtained. According to the connector press-fitting device with a check function for the attachment according to claim 1,
In order to press fit the connector mounted on the tray to the printed circuit board, when the connector is sucked by the press fitting head, it is impossible to insert the press fitting head into the check hole formed on the tray where this connector is mounted. The judgment is made, and based on this judgment result, it is judged whether or not the types of the press-fitting head and the connector correspond to each other.Therefore, there is a problem that the wrong type of connector is press-fitted into the printed circuit board. This can be prevented in advance, and the occurrence of defective products can be eliminated. That is, different types of connectors can be correctly press-fitted into the printed circuit board,
The productivity can be greatly improved. Also, simply
Since the check holes are only formed in the tray, the cost is hardly increased by adding the check function, which is economical.

According to the connector press-fitting device with a check function of the attachment as claimed in claim 2, when the press-fitting head is inserted into the check hole of the tray, the type of the press-fitting head and the connector placed on the tray are different. Therefore, it is possible to prevent the inconvenience of press-fitting a large connector by a press-fitting head having a small size. According to the connector press-fitting device with the attachment check function of the third aspect, when it is determined that the types of the press-fitting head and the connector do not correspond to each other, the press-fitting operation of the connector to the printed circuit board by the press-fitting head is stopped. Therefore, it is possible to reliably prevent press-fitting of different types of connectors into the printed circuit board, and it is possible to reliably prevent production of defective products.
