Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a leadless parts aligning device for aligning cylindrical leadless parts without lead wires in a pipe, in which a parts cassette for storing leadless parts is attached. In addition to simplifying the removal and greatly shortening the replacement time, it also prevents the leadless parts from falling from the parts cassette when replacing the parts cassette, and furthermore, it is possible to align the leadless parts 1 without stirring them too much. The purpose is to

Conventionally, an alignment device for arranging and storing leadless parts 1 as shown in FIG. 1 in a tube 2 as shown in FIG. It is composed of vertically erected pipes 4. The parts cassette 3 also includes a parts storage part 5 for storing the leadless parts 1, a pipe sliding hole 6 for protruding the tip 4a of the pipe 4 into the parts storage part 5, and a parts cassette. 3 is provided. This parts cassette 3 is fixed to a mounting plate 8 with bolts 9, as shown in FIG. In this alignment device, in the state shown in FIG. 4, by sliding the pipe 4 up and down or by swinging the parts cassette 3 together with the mounting plate 8, the tip 4a of the pipe 4 is moved from the pipe sliding hole 6 to the parts. Move it up and down to the storage part 5', thereby dropping the leadless component 1 into the pipe 4 from the tip 4a,
The leadless parts 1 are aligned within the pipe 4.

However, in such an alignment device, when the number of types of leadless parts 1 increases and the number of parts cassette sets 3 to be installed increases, it takes a long time to replace them, and when replacing the parts cassettes 3, it takes a long time. As shown in FIG. 5, the vibrator 4 comes out of the vibrator sliding hole 6, and at this time, the leadless component 1 in the component storage section 5 sometimes falls out of the parts cassette 3 from the vibrator sliding hole 6. In addition, vibe 4
move up and down in the parts storage section 5, and remove the leadless parts 1.
Since the parts were stirred, the leadless parts 1 rubbed against each other, and the paint on the surface of the leadless parts 1 was easily peeled off.

The present invention provides an apparatus for aligning leadless components to eliminate such conventional drawbacks, and the present invention will be described below with reference to the drawings of FIGS. 6 to 14.

FIG. 6 shows the overall structure of a leadless parts alignment device according to an embodiment of the present invention, and FIGS. 7 to 14 show the structure of its main parts. As shown in FIG. 7, the parts cassette 10 includes a parts storage part 11 for storing the leadless parts 1, and a large diameter part 12a provided downward from the bottom of the parts storage part 11 and having a large diameter. It consists of a vibrator sliding hole 12 having a small diameter portion 12b and a magnet 13 embedded in the bottom. Reference numeral 14 denotes a brush loaded in the large diameter portion 12a of the vibrator sliding hole 12 of this parts cassette 10, and as shown in FIGS. 8 to 10, this brush 14 has a large number of highly elastic bristles 15. It is constructed by rolling a plate-like object as shown in FIG. 8 into a cylindrical shape as shown in FIGS. 9 and 10A and b.

Reference numeral 16 denotes a vibrator inserted into the vibrator sliding hole 12 of the parts cassette 10. By moving the parts cassette 10 up and down so that the tip 16a of the vibrator 16 protrudes into the parts storage section 11, the inside of the vibrator 16 is inserted. The leadless components 1 are dropped into the holes, thereby making it possible to align the leadless components 1.

Reference numeral 17 denotes a mounting plate to which the parts cassette 10 is mounted, and this mounting plate 17 is provided with a through hole through which the vibrator 16 passes.

Further, as shown in FIGS. 11 and 12, a plurality of iron L-shaped brackets 18 are fixed to this mounting plate 17 at equal intervals with bolts 19, and a plurality of parts cassettes are held between them. 10, the parts cassette 10 is attached by the attraction force of the magnet 13 of the parts cassette 10. In the alignment device of the present invention having such a configuration, as shown in FIG.
When the vibrator 16 is not inserted into the vibrator sliding hole 12, the bristles 15 of the brush 14 are straight and close the vibrator sliding hole 12.

On the other hand, when the vibrator 16 is inserted, the bristles 15 of the brush 14 are curved along the vibrator 16, as shown in FIG. Then, as the parts cassette 10 moves up and down, the tip 16a of the vibrator 16 moves in and out of the parts storage section 11 of the parts cassette 10, thereby moving the leadless component 1 in the parts storage section 11 into the vibrator 16. and are arranged within it. Also, parts cassette 1
0 can be removed by simply lifting it by hand.At this time, the vibrator 16 is pulled out from the vibrator sliding hole 12, but since there is a brush 14, it can be removed by the bristles 15 as shown in Fig. 13. The leadless component 1 that is blocked and remains in the component storage section 11 will not fall through the vibrator sliding hole 12.

As described above, in the leadless component alignment device of the present invention,
Parts cassettes can be installed and removed very easily in a short period of time, increasing productivity, and since leadless parts do not fall from the parts cassette during installation and removal, there is no need to worry about dropping leadless parts. Collection work and waste of leadless parts can be eliminated, and since the vibrator is hardly moved, damage to leadless parts is reduced, and defects in leadless parts can be reduced.

As described above, according to the present invention, it is possible to obtain a leadless component aligning device that has a simple structure and high working efficiency.
