[Industrial applications]

 This invention relates to a connector delivery mechanism in a device for press-fitting a connector into a printed circuit board.

[0002]

[Prior art]

 Next, the structure of the conventional connector press-fitting device will be described with reference to FIG. In FIG. 3, 1 is a connector, 2 is a stocker, 3 is a transport mechanism, 4 is an insertion part, 5 is a moving mechanism, 6 is a press-fitting head, 7 is a press-fitting part, 8 is a printed circuit board, 9 is a die, and 10 is a table. It

In FIG. 3, a plurality of connectors 1 are accommodated in the stocker 2. The chuck 3A is held by the floating mechanism 3B and is connected to the cylinder 3C. The transport mechanism 3 horizontally moves the chuck 3A between the stocker 2 and the insertion section 4. The cylinder 3C moves the chuck 3A up and down.

The connector 1 taken out of the stocker 2 by the chuck 3A is inserted into the insertion portion 4, and the pins 1A of the connector 1 are aligned. The insertion portion 4 is elastically held by the mounting plate 5A, and the moving mechanism 5 reciprocates the insertion portion 4 under the press-fitting head 6 using the slide rail 5B that connects the mounting plate 5A and the substrate 5C as a guide.

The press-fitting head 6 adsorbs and desorbs the connector 1 and is connected to the cylinder 7 A of the press-fitting portion 7. The press-fitting portion 7 moves the press-fitting head 6 up and down with the guide shaft 7B held by the base 7D as a guide. The press-fitting part 7 lowers the press-fitting head 6 to mount the connector 1 on the printed circuit board 8.

The die 9 has the same arrangement as the through hole of the printed circuit board 8 and has an escape hole for the pin 1A. The die 9 is fixed to the table 10 on the bed 10A, and the table 10 moves in the XY directions by the designation of an NC device (not shown).

Next, a conventional delivery mechanism will be described with reference to FIG. FIG. 4 is an enlarged view of a main part of FIG. 3 according to an embodiment of the insertion portion 4 and the press-fitting head 6, and shows a state in which the insertion portion 4 is moved under the press-fitting head 6 in a state where the connector 1 is sucked by the insertion portion 4. Is.

In FIG. 4, the insertion portion 4 has a plurality of holes 14 A into which the pins 1 A of the connector 1 are inserted. The hole 14A has a tapered inlet, and the diameter of the hole 14A is larger than the tip portion 14 of the pin 1A and smaller than the press-fitting portion 11 of the pin 1A, so that the pin 1A of the connector 1 is inserted into the insertion portion 4. It is easily aligned.

In FIG. 4, the press-fitting head 6 is provided with a plurality of holes 6A into which the upper portions 13 of the pins 1A are inserted, and the press-fitting surface 6B of the press-fitting head 6 contacts at the mounting portion 12 of the pin 1A. In FIG. 4, the press-fitting head 6 descends at the press-fitting portion 7, and the upper portion 13 of the pin 1A is inserted in the hole 6A. The hole 6A penetrates the hollow portion 6C, and the vacuum pump connected to the hollow portion 6C depressurizes the hollow portion 6C to adsorb the connector 1 to the press-fitting head 6. In FIG. 4, when the connector 1 is attracted to the press-fitting head 6 and the press-fitting head 6 is raised, the insertion part 4 returns to the state shown in FIG.

3 and 4 are technically the same as FIGS. 1 and 3 of Japanese Patent Laid-Open No. 5-32611.

[0011]

[Problems to be solved by the device]

 In FIG. 4, the positional relationship between the insertion portion 4 and the press-fitting head 6 needs to be accurately positioned by the moving mechanism 5. When the positioning accuracy is poor, the press-fitting surface 6B of the press-fitting head 6 comes into contact with the pin 1A and the upper portion 13 of the press-fit connector 1, and in the worst case, delivery is impossible. Therefore, there is a problem in that the assembly work of the apparatus requires high-precision adjustment, and the moving mechanism 5 is an expensive mechanism because it precisely processes parts.

According to this invention, the insertion portion is composed of an insertion block, a case and a pin, a hole is formed in the insertion block for receiving a connector pin, and the case holds the insertion block so that it can be finely moved on a plane, and the pin is inserted. Standing on the block, the press-fitting head aims to provide a connector delivery mechanism that forms a reference hole for the pin to enter.

[0013]

[Means for Solving the Problems]

 In order to achieve this object, in the present invention, the connector 1 is held by the chuck 3A from the stocker 2 in which the plurality of connectors 1 are accommodated, and the transport mechanism 3 moves the chuck 3A to insert the connector 1 into the insertion portion 4. The moving mechanism 5 moves the connector 1 of the insertion portion 4 below the press-fitting head 6, the press-fitting head 6 adsorbs the connector 1, and the press-fitting portion 7 lowers the press-fitting head 6 to move the printed circuit board 8 In the device for mounting the connector 1 on the connector 1, the insertion portion 4 is composed of an insertion block 41, a case 42 and a pin 43. The insertion block 41 is provided with a hole 4A into which the tip portion 14 of the pin 1A of the connector 1 is inserted, and the case 42 is The insertion block 41 is held so that it can be slightly moved on a plane, and is elastically held on the moving mechanism 5, the pin 43 is erected on the insertion block 41, and the press-fitting head 6 has a reference hole 6D into which the pin 43 is inserted. Formation It is.

[0014]

[Action]

 Next, the structure of the connector delivery mechanism according to the present invention will be described with reference to FIG. In FIG. 1, 41 is an insertion block, 42 is a case, 43 is a pin, and others are the same as those in FIG. That is, FIG. 1 shows the insertion portion 4 of FIG. 4 which is composed of an insertion block 41, a case 42 and a pin 43.

In FIG. 1, the pin 1 A of the connector 1 is in the hole 4 A of the insertion block 41, and the connector 1 moves only about ± 50 μm on the plane with respect to the insertion block 41.

The insertion block 41 is constrained by the case 42 in the vertical direction in FIG. 1, but is movable in the front-rear direction, the left-right direction, and the diagonal direction by the gap with the case 42. The case 42 pushes the insertion block 41 from four directions by the compression coil springs 4B, so that the case 42 is in a balanced state. That is, the insertion block 41 of the insertion portion 4 in FIG. 1 is a so-called floating mechanism.

The positional relationship between the two pins 43 attached to the insertion block 41 and the hole 4A of the insertion block 41 is the same as the positional relationship between the two reference holes 6D and the hole 6A of the press-fitting head 6. Therefore, when the press-fitting head 6 descends, the pin 43 first enters the reference hole 6D.

In FIG. 1, a tapered portion 43A is formed at the tip of the pin 43. Therefore, when the positions of the press-fitting head 6 and the insertion portion 4 are deviated, the pin 43 is guided by the taper portion 43A, and the insertion block 41 can be moved to correct the positional deviation. Then, the press-fitting head 6 enters the housing 1B, and the upper portion 11 of the pin 1A is inserted into the hole 6A of the press-fitting head 6.

Next, the hollow portion 6C of the press-fitting head 6 is depressurized from the atmospheric pressure state, the connector 1 is held by vacuum suction from the hole 6A, and the head 6 is lifted to complete the delivery operation.
