DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an automatic parts assembly apparatus according to the present invention will be described below with reference to the accompanying drawings.

The automatic component assembly device of the present invention in this embodiment includes a support 2 that supports a concave component 1 provided with a circular concave portion, a guide member 4 that guides a round bar-shaped convex component 3, and X to linearly move the guide member 4 in the X direction and the Y direction on the horizontal plane
It includes a direction cam mechanism, a Y direction cam mechanism, an X direction slide mechanism, and a Y direction slide mechanism.

The cam mechanism for the X direction and the cam mechanism for the Y direction are
Two first cams 13 and a second cam stacked on the same rotating shaft (linked to a drive source not shown).
Cam 14 and its first cam 13 and second cam 1
The first cam follower 7 and the second cam follower 12 are arranged so as to follow the rotation of the cam follower 4 in the right angle direction, respectively, and the two square rod-shaped cam followers 12 that support the first cam follower 7 and the second cam follower 12, respectively, 1 support member 6 and second support member 11
It consists of.

The slide mechanism for the X direction and the slide mechanism for the Y direction have two parallel first slide rod members 5 supported by four first slide bushes 8 so as to be slidable in the X direction, and the same four second slide rod members 5. It consists of two parallel second slide rod members 9 supported on the slide bush 10 so as to be slidable in the Y direction orthogonal to the X direction, and the first support is provided at approximately the middle of the first slide rod member 5. Both ends of the member 6 are fixed, and the second
Both ends of the support member 11 are fixed, and the four first slide bushes 8 are fixed to the second slide rod member 9.

The guide member 4 has a rectangular parallelepiped shape, and is provided with a guide hole 15 in the center thereof through which the convex part 3 can be vertically inserted.
Fix it to one end surface of.

The support 2 has a shallow shape capable of supporting the concave part 1, and is supported so as to be movable up and down by a lifting cylinder 16. Furthermore, the support 2 and the lifting cylinder 16 are connected via a block 17 to a forward/backward cylinder 18. It is supported so that it can move forward and backward.

The automatic component assembling device of the present invention in this embodiment has the above-mentioned configuration, and an example of its use will be described below.

First, the concave part 1 is set on the support 2 and raised by the lifting cylinder 16, while the convex part 3 is inserted into the guide hole 15 of the guide member 4 from a supply unit (not shown) such as a vibrating feeder. It is supplied via a feed path (not shown) such as a pipe.

At this time, the center of the convex part of the convex part 3 O ₃ - O ₃
and the center O ₁ −O ₁ of the concave part of the concave part 1 is the fourth
As shown in Figure B, if they match without variation, the convex part 3 will automatically fit into the concave part by its own weight, and the two members 1 and 3 will be automatically assembled. Become.

Here, the center O ₃ −O ₃ of the convex part of the convex part 3,
The center O ₁ −O ₁ of the concave part of the concave part 1 is as shown in FIG. 4A.
As shown in , if there is variation, the convex part 3 gets caught on the periphery of the concave part of the concave part 1 and is not fitted into the concave part of the concave part 1, and the two parts 1 and 3 are automatically separated. cannot be incorporated into

Therefore, the first cam 13 and the second cam 14 are rotated by rotating the rotating shaft. Then, the first cam follower 7 and the second cam follower 12 follow in the X direction and the Y direction, and accordingly, the first slide rod member 5 and the second slide rod member 9
are the first support member 6 and the second support member 1, respectively.
The guide member 4, which is fixed to the first slide rod member 5, moves in the X and Y directions. As a result, the convex part 3 guided by the guide member 4 moves in the X and Y directions on the horizontal plane on the concave part 1, and changes the position of the concave part of the concave part 1 supported by the support 2. When the guided convex part 3 matches the guide hole 15 of the guide member 4, the convex part 3 is fitted into the recess of the concave part 1 by its own weight.

In this way, the center of the convex part of the convex part 3 O ₃ −O ₃
and the center O ₁ −O ₁ of the recess of the concave part 1, a fourth
As shown in Figure A, even if there are variations,
As shown in FIG. 4B, the two parts 1 and 3 can be reliably and automatically assembled.

Once the convex part 3 is fitted into the recess of the concave part 1, the support 2 is lowered by the lifting cylinder 16 to release the convex part 3 from the guide member 4, and the support 2 is moved into the forward/backward cylinder. 18 and raised again by the lifting cylinder 16, and the above-described operations are repeated to fit the convex part 3 into the recess of the concave part 1.

In the above embodiment, the concave part 1 is supported by the support 2, the convex part 3 is guided by the guide member 4, and the convex part 3 is inserted into the concave part 1. However, on the contrary, the convex part 3 is supported by the support 2, the concave part 1 is guided by the guide member 4, and the concave part 1 is fitted onto the convex part 3. It's okay.

Moreover, the sliding direction of the first slide rod member 5 and the second slide rod member 11, that is, the X direction and the Y direction.
Although the directions are orthogonal to each other, they do not necessarily need to be orthogonal to each other.

[Effect of idea]

As is clear from the above, the automatic component assembly device of the present invention includes a guide member that guides one component vertically and penetratingly, and a guide member that is disposed under the guide member so as to be movable up and down. and a support member that supports the guide member in the X direction and the Y direction slide mechanism,
Supported so that it can be moved linearly back and forth in the direction and the Y direction,
A cam mechanism for the X direction and a cam mechanism for the Y direction are respectively linked to the slide mechanism for the X direction and a slide mechanism for the Y direction, and a drive source is linked to the cam mechanism for the X direction and the cam mechanism for the Y direction. By moving one component guided by the guide member in the X direction and the Y direction on the horizontal plane on the other component supported by the support member, the center of one component and the center of the other component can be aligned. Once matched, one part can fit into the other part under its own weight. Therefore, 2
Even if there is variation in the center of each part, the variation in the center of the part can be absorbed and the two parts can be automatically assembled.

Note that, as a matter of course, the automatic component assembling apparatus of the present invention is not limited to the above-described embodiments.
