Description

[Detailed Description of the Invention] The present invention relates to a component mounting device that automatically supplies a headed bar and a perforated component, incorporates these components, and then mounts them at a predetermined position.

Conventionally, after assembling perforated parts such as washers and rollers into headed rods such as screws and rivets, when attaching these to predetermined positions on the other object, the fourth
A component mounting device 31 as shown in the figure is used. This component mounting device 31 has a chuck body 32, and a pair of first chuck pawls 53 are disposed on this chuck body 32.
The tip of is biased to be in a normally closed state. The opposing first chuck pawls 53 form a first holding hole 39 for holding a screw (not shown) fed from the screw guide hole 54. moreover,
A second chuck pawl 55 is disposed in front of the first chuck pawl 53, and its tip is biased so as to be in a normally closed state. The opposing second chuck claws 55 form a second holding hole 56 that is close to the first holding hole 39 and holds a washer (not shown), and the first holding hole 39 and the second holding hole 5
A communication hole 42 is formed that communicates with each other. Therefore, the component mounting device 31 has the first chuck claw 5.
The screw is held in the first holding hole 39 of No. 3, a washer is held in the second holding hole 56, the screw is pushed out of the first holding hole 39 by movement of the bit 34, the washer is incorporated into the screw, and the bit 34 is further moved. The screw and washer are pushed out of the first chuck pawl 53 as the screw and washer are moved, and are attached to a predetermined position on a mating object (not shown). In this component mounting device, when the bit 34 is arranged so as to move in the horizontal direction, the first chuck claw 53 is
When the second holding hole 56 is expanded after the holding hole 39 is expanded by the movement of the screw, the position of the washer held therein may be eccentric from the center, and the screw may sometimes be inserted into the hole of the washer. The wax is falling off the chuck nail without any effort. As a result, the washer may not be incorporated into the screw, resulting in disadvantages such as the inability to reliably perform the desired component attachment work. In addition, in the above-mentioned component mounting device, air is supplied to the washer, which has almost no wall thickness, so when the washer comes into contact with the second chuck pawl 55, the second chuck pawl 55 is pushed open, and the washer is inserted into this gap. In this case, it is not possible to incorporate the washer into the screw, resulting in a disadvantage that it is impossible to perform the desired part attachment work.

The purpose of this invention is to eliminate the above drawbacks.
Examples will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a component mounting device, which has a chuck body 2 arranged horizontally.
A bit guide hole 3 is bored in this chuck body 2, and a bit 4 passes through this hole and is movably arranged. In addition, a feed pipe 6 having a pin guide hole 5 located across the bit guide hole 3 is rotatably arranged in the chuck body 2, and when the bit 4 is moved, it is placed outside the moving path of the bit 4. Configured to be extruded. Furthermore, a pair of chuck pawls 7 are arranged on the chuck body 2 so as to block the movement path of the bit 4, and the tips of the chuck pawls 7 are always biased to be in a closed state. Furthermore, when the chuck pawl 7 is in the closed state, it forms a first holding hole 9 for holding a pin 21 to be assembled into a perforated part (hereinafter referred to as part) 8, which will be described later.

On the other hand, an auxiliary claw 10 is arranged on the chuck main body 2 and extends parallel to the chuck claw 7 at a position that blocks the movement path of the bit 4.
0 is formed into a substantially L-shape so that its tip is located close to the chuck pawl 7. Also,
The auxiliary claw 10 is biased by a spring so that its tip is closed, and has a communication hole 12 whose center coincides with the first holding hole 9 of the chuck claw 7, and a guide hole extending in a direction intersecting the first holding hole 9 and communicating therewith. 11 and an insertion hole 13 into which a receiving portion 16 of a component receiving stand 15 to be described later is inserted.

Further, a component holder 15 is fixed to the chuck body 2, and has a horizontally extending inner hole 14 equal to the diameter of the desired perforated component and a semicircular arc portion holder 16 continuous to the inner hole 14. The part 16 is disposed in the insertion hole 13 of the auxiliary claw 10 to cover the forward side of the guide hole 11, and the perforated part supplied from the guide hole 11 is positioned to coincide with the center of the communication hole 12. has been done. The parts holder 15
has a cylindrical portion 17 at its front end, and an auxiliary cylinder 18 is detachably attached to this cylindrical portion 17. The inner diameter of this auxiliary cylinder 18 is equal to the inner diameter of the inner hole 14 of the component holder 15.
, and is set to be slightly larger than component 8. Further, a component guide 19 for guiding the component 8 is provided on the component holder 15.
is attached, and the component guide hole 20 of the component guide 19 is configured to communicate with the guide hole 11 of the auxiliary claw 10.

In the above component mounting device, as shown in FIG. and is held on a component holder 15. Thereafter, as shown in FIG. 3b, the bit 4 moves to push out the pin 21 from the chuck pawl 7, and at the same time inserts the tip of the pin 21 through the communication hole 12 of the auxiliary pawl 10, and then inserts it into the hole of the component 8. I have it inserted. At this time, even if the bit 4 pushes open the chuck claw 7 and the auxiliary claw 10, the component 8 is securely held in the component holder 15 and will not move at all, so the pin 21 will surely hold the component 8. Incorporate. Furthermore, when bit 4 moves, pin 21 also moves,
The component 8 slides through the inner hole 14 of the component holder 15, pushes open the auxiliary claw 10, and separates therefrom.
Furthermore, the part 8 slides inside the auxiliary cylinder 18 and the pin 2
It is securely installed near the bottom of the neck of 1. Furthermore, the third
As shown in FIG.
Part 8 is attached to counterpart 22.

As explained above, the present invention is provided with a chuck pawl and an auxiliary pawl, and the chuck pawl guides the headed bar and the auxiliary pawl guides the perforated part. Since the head bar is configured to hold the perforated part by the bit, the position of the perforated part does not change even if the auxiliary pawl is pushed open when the headed bar is pushed out from the chuck pawl by the bit. Not only can the perforated part be reliably assembled into the auxiliary claw, but even when the perforated part is fed with air and reaches the specified position, the auxiliary claw will not be pushed open, and the perforated part will not fall off from the auxiliary claw. There are advantages such as no problems. In addition, since the present invention is configured so that the perforated part slides inside the auxiliary cylinder,
It has the advantage that the perforated part can be reliably assembled near the bottom of the neck of the headed bar.
