The table section 24 includes a table moving mechanism 37 that holds the printed circuit board 19 and positions a predetermined insertion hole of the printed circuit board 19 at the insertion position 18 directly below the insertion section 17, and a predetermined leg of the inserted connector. A bending mechanism 38 is provided for bending the printed circuit board 19 from the back surface thereof.

To explain the overall function, feeder 8A
The connector supplied from etc. is cylinder 29A
The moving passage 10 is held by the holding claws 28 pushed down by the rotation table 26, and
is transferred along the rotation station 13 and rotated by +90 degrees or -90 degrees by the action of the cylinder 30 or 31, and the transfer station 14
, it is pushed down by the cylinder 32 and held again by the delivery mechanism 33, and further inserted into the insertion portion 17.
It is positioned between the holding claws 34 of. After that, the holding claw 34 closes to hold the connector, and at the same time, the grip of the delivery mechanism 33 is released to complete the delivery.After that, the connector is rotated at 0 degrees or 90 degrees on one side around the Z axis.
It is rotated once and lowered, and inserted into a predetermined insertion hole of the printed circuit board 19 in a predetermined direction.

After that, the bending mechanism 38 bends the printed circuit board 1.
The connector is fixed to the printed circuit board 19 by bending predetermined legs protruding from the back side of the connector 9.

Selection of the order in which connectors are supplied from each feeder 8A etc. to the holding mechanism 25, rotation station 13
selection of the rotation angle of +90 degrees or -90 degrees in the insertion section 17, selection of the rotation angle of 0 degrees or 90 degrees on one side in the insertion section 17, and the selection of the rotation angle of the printed circuit board 1 by the table moving mechanism 37.
The selection of the positions 9 is performed according to a program or manually as necessary, in accordance with a predetermined order.

The connector supplying device in the feeder (8C for example) for the supply station (9C for example) will be described. The other supplying devices have a similar configuration.

The supply station 9C is a station fixed to the space.
As shown in FIG. 2, a connector supply device 201 is provided at a portion C. As shown in FIG. The supply device 201 includes a transfer means 202 and a connector receiver 203.

Regarding details of the supply device 201, No. 6, 7, 8,
This will be explained with reference to Figures 9 and 10. The transport means 202 is
As shown in FIG. 9, a guide groove 204 for guiding the lower leg 3 of the connector 4 and a receiving groove 20 for receiving the main body 1
5, and is adapted to move the connector 4 in the transfer direction 206 by a vibrating feeder method.

The connector receiver 203 is provided with a guide block 207.
A connector receiving block 208 is provided which is guided by the guide block 207 so as to be reciprocally movable in a direction perpendicular to the conveying direction 206. A pull spring 212 is provided between a pin 210 of a frame 209 fixed to the guide block 207 and a pin 211 of the connector receiving block 208, and always applies a force pulling the connector receiving block 208 towards the frame 209.
The action of the cylinder 213 causes it to move in the opposite direction against the force of the tension spring 212 .

The connector receiving block 208 has a guide groove 214 for guiding the lower leg 3 of the connector 4 and a receiving groove 215 for receiving the main body 1, as shown in FIG. The stroke of the connector receiving block 208 is adjusted by set screws 216 and 217, and at the position closest to the frame 209, the guide groove 214 is in line with the guide groove 204, and at the position farthest from the frame 209, moved by the stroke S. , reaches the center 218 of the supply station 9C on the moving path 10. Connector receiving block 208
The length of the connector 4 is the same as the length of the connector 4 that is supplied at the supply station (9C in this case) up to the inside of the stopper 219 at the end.

A holding mechanism 25 that moves along the moving path 10
stops intermittently just above the center 218 of each supply station (9C in this case), descends, grips the upper leg 2 of the connector 4 at the center 218 with the gripping claw 28, and then The connector 4 is lifted up to be held and supplied to the holding mechanism 25.

To explain the operation, the connector 4 is fed from the cylindrical feeder 8C which also serves as a reservoir, with its vertical direction and transport direction aligned.
The lower legs 3 are guided by the guide groove 204 and are successively transferred one by one along the transfer means 202. If the guide groove 214 of the connector receiving block 208 is positioned on the extension of the guide groove 204 of the transfer means 202, the connector 4 of the earlier application will be pushed by the next object and enter the guide groove 214 and the connector receiving block 208 It is accommodated in the stopper 219 and stopped.

Next, the cylinder 213 is activated to move the connector receiving block 208 to position the guide groove 214 at the center 218 of the supply station 9C, and the clamping claw 28 that was waiting just above it is lowered to clamp the connector 4. Clamping claw 28 again
Raise the connector and remove it.

During this time, the next connector is transferred by the transfer means 202, but the next connector is transferred to the connector receiving block 208.
Therefore, only one connector can be reliably isolated and taken out, and there is no interference with the next connector, and it can be smoothly supplied to the gripping claws 28 without any hindrance. .

Other supply stations 9A, 9B, 9D, 9E
A similar operation is performed in .

The connector receiving blocks at each supply station 9A etc. are always replenished with connectors of the type supplied by that station. A predetermined holding mechanism 25 holds predetermined types of connectors at a predetermined supply station and transfers them in a predetermined order by a predetermined program or manual operation.

The present invention includes a conveying means having a groove for guiding the lower leg of the connector and conveying the connector in the longitudinal direction, and a conveying means located at the end of the conveying means, the connector 1
a connector receptacle with a length that accommodates the
The connector receiver is supported so that it can reciprocate in a direction perpendicular to the connector transfer direction, so that it can reliably take out and supply connectors one by one smoothly in the same direction, making it a high-speed, highly reliable automatic connector insertion device. It is possible to provide a connector supply device that makes it possible to realize the above, and has extremely great practical effects.
