Description

[Detailed description of the invention] The present invention relates to a thin shaft aligning and feeding device that is effective for automatically inserting fine shafts such as terminal pins of electronic components at equal intervals and soldering them at equal intervals. The aim is to provide a device that can line up a large number of books without missing anything.

As shown in Fig. 1, some conventional fine-axis alignment and feeding devices include a parts feeder 1 equipped with a multi-row feeding section 2 to simultaneously feed a large number of parts, but the device itself is complicated and disadvantageous in terms of cost, and it is technically difficult. However, it also had the disadvantage of not being able to provide a stable supply due to the narrow pitch spacing.

In addition, as shown in Figs. 2 and 3, the thin shafts 4 supplied from the parts feeder 3 are fed into the pallet 5 formed in a step-like manner, and the thin shafts 4 fed to the top stage are successively pushed downward by gravity. There is also a device that allows the fine shafts 4 to be dropped and aligned, but this has the disadvantage that the thin shaft 4 may be missing teeth or tilted, making stable supply impossible.

The present invention eliminates the above-mentioned drawbacks of the prior art.

Embodiments of the present invention will be described below with reference to FIGS. 4 to 8.

Reference numeral 6 denotes a parts feeder into which a large number of thin shafts 7 are input and continuously feeds out the thin shafts 7 one by one using minute vibrations.A feeder 8 is connected to this parts feeder 6, and a groove is provided at the tip of the feeder 8. Palette 9
is slidably and rotatably arranged on a slide shaft 17 held in a bearing 16. A photodetecting element 10 is placed close to the grooved pallet 9, and detects whether or not the thin shaft 7 is fed into one groove of the grooved pallet 9. When this photo-detecting element 10 detects that the thin shaft 7 is fed into one groove of the grooved pallet 9, the power to the parts feeder 6 and feeder 8 is cut off to stop feeding the thin shaft 7, or the feeder 7 is stopped in the operating state. With the grooved pallet 9 still in place, the cam follower 13 is moved by the cam 12 attached to the motor 11.
The thin shaft 7 is slightly rotated in the direction in which it is fed through the . That is, the grooved pallet 9 is moved from the tip of the feeder 8 to the state shown in FIG. 6 from the state shown in FIG.
move in the direction away from.

Furthermore, this grooved pallet 9 is
The grooved pallet 9 is moved by one pitch of the groove by the cam 14 via the cam follower 15, and then the grooved pallet 9 is moved to the feeder 8 side by the motor 11 via the cam 12 and the cam follower 13, resulting in the state shown in FIG. do.

When the operation of the grooved pallet 9 is completed, the parts feeder 6 and the feeder 8 are turned on and the thin shaft 7 is fed into the groove of the grooved pallet 9.

By repeating this operation, the thin shafts 7 can be aligned on the grooved pallet 9 as shown in FIG. Note that the grooved pallet 9 is provided with springs 18 and 19 that are brought into pressure contact with both cam followers 13 and 15.
is being strung up.

Since the thin shaft alignment and feeding device of the present invention is configured as described above, it is possible to reliably feed the thin shafts in a single line, eliminating missing teeth and inclinations, and there is no interference between the end faces of the thin shafts during lateral movement, so the shaft diameter This makes it possible to arrange the lines at narrow pitches up to the same pitch, and the structure is simple and highly reliable, which is of great practical value.
