Waiting at the press-in position a, connector 1
The angle of the head 25 is determined by the head rotation mechanism 430, and the angle of the anvil 48 is determined by the swing mechanism 540. While receiving the lower surface of the board 2, the anvil 48 is provided with a pressure-resistant function by the pressure-resistant mechanism 520, and the head 25 is downwardly pressurized by the pressing mechanism 440 to press-fit the connector 1. Can be performed automatically.

Therefore, the connector 1
A series of press-fitting operations can be automated only by spending human time only on the work of temporarily attaching the, and the assembling time can be greatly reduced.

Further, if the shape and the mounting direction of the connector 1 are different, if the contact pin 3 of the connector 1 is bent or the mounting position is misaligned, the head 25 ends with the connector 1 even if the head unit 200 is lowered. Since the collision with the inlet 1-1 or the tip of the contact pin 3 causes the head stop position to be higher than that at the time of normal fitting and the sensor 58 which is turned on at the normal fitting position does not operate, pressure cannot be applied. become.
Therefore, by checking the fitting between the connector 25 and the head 25 for press-fitting immediately before press-fitting, it is possible to drastically reduce defective assembly.

Rotation mechanism), the anvil angle is determined by anvil control means (swinging mechanism), and then the anvil is raised by the anvil control means (anvil lifting mechanism) to temporarily attach the backboard connector. Receiving part and anvil control means (pressure-resistant mechanism) The breakdown voltage function is given to more anvil,
These series of operations can be automatically performed so that the head is lowered and pressurized by the head control means (pressing mechanism) to press-fit the connector.

Accordingly, the assembly time can be greatly reduced by automating a series of press-fitting operations by only spending human time only for temporarily attaching the connectors to the backboard.

Further, according to the connector press-fitting device of the present invention, when the head unit is lowered, the sensor means for detecting the height of the head unit and checking the engagement between the connector and the head is provided. If there is a difference in the shape or mounting direction of the connector, the bending of the contact pin of the connector, or the mounting position, the tip of the head collides with the inlet of the connector or the contact pin even if the head unit is lowered. The head stop position becomes higher than that at the time of normal fitting, and the height of the head unit is detected by the sensor means so that the head cannot be pressurized. That is, since the sensor does not operate because the shutter does not block the sensor, pressure cannot be applied.

Therefore, it is possible to check the fitting between the head and the connector immediately before press-fitting, and it is possible to reduce defective assembly.
