[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for inspecting a chip suction nozzle which is used in a high-speed automatic mounting apparatus for chip parts and which mounts the chip parts on an assembled structure by suctioning the chip parts by vacuum.

[0002]

2. Description of the Related Art FIG. 5 shows an overall configuration of an example of a conventional high-speed automatic mounting device for chip components as described above, and FIG. 6 shows a perspective view of a mounting head supporting a plurality of chip suction nozzles. FIG. 7 shows a series of operation explanatory diagrams illustrating how the mounting head sucks the chip component, mounts the chip component on the assembled component, and returns to the chip supply unit again.

In each drawing, one mounting head indicated by reference numeral 1 supports five chip suction nozzles 2 in a circle, and the mounting head 1 thus configured is supported by a rotary table 3 and is formed in a circle. Are arranged.

[0005] That is, in FIG. 5, chips (not shown) fed by the chip supply / conveyance section 4 are adsorbed by the respective chip suction nozzles 2 of the mounting head 1a located in the chip supply section 5 (see FIG. 7), and clockwise. To rotate.

Here, a series of operations of the mounting head 1 are shown in FIG.
In brief , the mounting head detects the thickness of the chip and selects the mounting method at the position 1b, recognizes the chip at the position 1c, corrects the orientation of the chip at the position 1d, and then corrects the position 1e. In (2), the chip is mounted on an assembly component (not shown). After the mounting of the chip, the defective chip is discharged at a position 1f, and thereafter, the chip suction nozzle 2 is discharged at a position 1g.
Is selected and the operation of returning the chip suction nozzle 2 to the origin is performed at the position 1h, and then the chip is suctioned to the chip suction nozzle 2 again at the position 1a described above.

The structure of the single mounting head 1 and the chip suction nozzle 2 described above with reference to FIGS. 8 and 9 will be described. The mounting head 2 communicates with the lower end of a hollow shaft portion 6 through the shaft. A tubular body 7 is provided. A pair of opposed axially long guide holes 8 and 8 are formed in the cylindrical body 7, and guide grooves 9 and 9 are formed on the inner surface of the cylindrical body 7 in a direction orthogonal to the guide holes 8 and 8. 9, 9 are formed as socket grooves 9 a, 9 a in the circumferential direction on the bottom side of the cylindrical body 7.

After being inserted into the inside, the rotation of the collet chuck 26 is prevented by pressing the rotation stop pin 24, and thereafter,
The collet chuck 26 is non-rotatably fixed by rotating the fixed handle 25 in the tightening direction. Further, by rotating the handle 25 with the rotation stopping pin 24 pulled out, the chip suction nozzle 2 can be rotated together with the collet chuck.

On the other hand, an X-axis stage 27 is fixed on the table 20, a Y-axis stage 28 is supported on the X-axis stage 27, and a Z-axis stage 30 is supported on the Y-axis stage 28. . And Z axis stage 3
At 0, a first rod 32 is supported via a fixed block 31. At one end of the first rod 32, the length of the above-described tip suction nozzle 2 is measured via an angle-adjustable first joint 33. A gauge 34 with a length measuring dial is supported. The dial of the gauge 34 is indicated by reference numeral 35.

At the other end of the first rod 32, one end of a second rod 37 is supported via a second joint 36.
One end of a third rod 39 is supported on the other end of the second rod 37 via a third joint 38 whose angle is adjustable, and the other end of the third rod 39 has a tip suction nozzle 2
An eccentricity measuring gauge 40 with a dial for measuring eccentricity is supported. The dial of the gauge 40 is indicated by reference numeral 41.

With this configuration, the above-described gauge 34 with a dial for measuring length and the gauge 40 with a dial for measuring eccentricity can be arranged so as to face in a right angle direction.

By rotating the X-axis adjustment grip 42 provided on the X-axis stage 27 by the above-described configuration, the Y-axis stage 28 and the Z-axis stage 30 can be used together with the gauge 34 with a length measuring dial and The gauge 40 with the eccentricity measuring dial can be slid and adjusted in the X-axis direction, that is, in the left-right direction with respect to the chuck insertion portion 22.

Further, by rotating the grip 43 for adjusting the Y axis provided on the Y axis stage 28, the gauge 34 with the length measuring dial and the gauge 40 with the eccentricity measuring dial are chucked together with the Z axis stage 30. Part 2

By rotating the Z-axis adjusting grip 44 provided on the Z-axis stage 30, the gauge 34 with a length measuring dial and the gauge 40 with an eccentricity measuring dial are attached to the chuck insertion portion 22. The slide adjustment can be performed in the Z-axis direction, that is, the vertical direction.

Next, the procedure for measuring the length and the eccentricity of the chip suction nozzle 2 using the chip suction nozzle inspection apparatus configured as described above will be described.

First, as shown in FIG. 3, the suction nozzle 2 is press-fitted into the chuck insertion portion 22 of the chuck fixing head 21.
After the fixed collet chuck 26 is inserted, it is non-rotatably fixed by the rotation stopping pin 24 and the fixed handle 25.

In the set state of the suction nozzle 2,
Preliminary adjustment of the gauge 34 with the dial for length measurement and the gauge 40 with the dial for eccentricity measurement is performed. First, the first joint 33 and the third joint 38 are adjusted so that the tip of the gauge 34 with the dial for measuring length and the tip of the gauge 40 with the dial for measuring eccentricity have the same height. Next, the Z-axis adjustment grip 44 is rotated to the height at which the centers of the gauges 34 and 40 with the dial coincide with the center of the collet chuck 26, and the Z-axis stage 30 is slid and adjusted. Finally, the Y-axis adjustment grip 43 is rotated to move the Y-axis stage 28 so that the tip of the gauge 34 with a length measuring dial reaches the tip of the chip suction nozzle 2 supported by the collet chuck 26. Adjust the slide. At this time, the dial reference scale position of the gauge 34 with a length measuring dial corresponds to the case where the tip suction nozzle 2 has a normal length.

After the preliminary adjustment as described above, first, the length of the chip suction nozzle 2 is measured according to the procedure shown in FIG. FIG. 4A shows the final stage of the above-mentioned preliminary adjustment. From this state, by rotating the X-axis adjusting grip 42 and sliding the gauge 34 with the length measuring dial in the direction of the arrow, as shown in FIG. 4B. Then, the tip of the gauge 34 comes into contact with the tip of the tip suction nozzle 2, and the pointer of the dial 35 changes with respect to the reference graduation position in accordance with the degree of wear (or loss) of the tip of the nozzle. By reading the changed pointer of the dial 35, the degree of wear (or loss) of the tip suction nozzle 2 can be measured.

After the measurement of the degree of wear of the tip suction nozzle 2 is completed, the grip 42 for adjusting the X-axis is further rotated to slide the gauge 34 with the length measuring dial in the direction of the arrow, as shown in FIG. As shown, the tip of the gauge 40 with the eccentricity measuring dial is the tip suction nozzle 2
Abut on the sides. In this state, when the rotation stop pin 24 of the chuck fixing head 21 is pulled out, the tip suction nozzle 2 can be rotated together with the collet chuck 26 by rotating the fixed handle 25. Therefore, the eccentric state of the tip suction nozzle 2 is measured by eccentricity measurement. It can be measured by a change in the scale of the pointer of the dial 41 of the gauge 40 with a dial for use.

As described above, according to the present invention, the use of the chip suction nozzle inspection apparatus makes it possible to easily detect the degree of wear, chipping, and eccentricity of the chip suction nozzle, thereby assembling chip parts. There is an advantage that the mounting accuracy on the structure can always be maintained.
