[Problems to be solved by the invention] As mentioned above, in the conventional component insertion device, the diameter of the components handled such as lead wires is small, and the overall size of these components is also small. It is difficult to supply a large amount of parts to a jig with a large amount of parts and to efficiently align them, and the problem is that the force and the pitch of the part receiving holes have to be large, which reduces the number of parts that can be stored in the jig as a whole. It was hot.

[Purpose of the invention] This invention was made to solve the above-mentioned problems, and it is possible to have a component receiving hole formed with a pitch close to the mechanical limit without increasing the pitch of the component receiving hole. The purpose of the present invention is to provide a component insertion device that can easily feed components into a jig, accept a large number of components into the jig at once, and improve production efficiency by enabling mass processing in subsequent processes. do.

[Means for solving the problem] The component insertion device according to this invention uses a jig having multiple rows of component receiving holes formed at a predetermined pitch.
An intermittent moving means for intermittently moving the component insertion guide to just below the component supply port, and a component receiving hole provided in the jig were supplied with components every other pitch in the width direction from the first row to the last row. After that, a rotation means is used to rotate the jig 180 degrees in a horizontal plane, and after the rotation is reversed by this rotation means, the jig is returned to its initial position, and the remaining parts are placed in every other pitch of the component receiving hole. The apparatus is provided with a supply means for sequentially supplying predetermined components from the component supply port of the component insertion guide, row by row, up to the last row.

[Function] In the component insertion device according to this invention, the jig is intermittently slid along the rail for each row of component receiving holes by the intermittent moving means, and the jig is intermittently slid along the rail from the component supply port of the component insertion guide to a predetermined position. The parts are supplied to the component receiving holes of the jig every other pitch in the width direction of the jig, from the first row to the last row, and when the parts have been supplied to the last row, the jig is rotated. After being rotated 180 degrees in a horizontal plane by the means, the parts are returned to the initial position, and the parts are intermittently fed into the remaining part receiving holes every other pitch from the first row to the last row by the supply means. is supplied to

[Example] An example of this invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing the main structure of the component insertion device of this invention, FIG. 2 is a front view thereof, and FIG.
The figure is also a side view.

In these figures, the component insertion device has the following configuration.

That is, a movable table 3 is provided on rails 2, 2 extending in the left-right direction in FIG. 1 so as to be able to move intermittently.
As shown in FIG. 2, a rotary table 5 is provided on the movable table 3 via a bearing 4 so as to be rotatable by 180 degrees in a horizontal plane.

This rotary table 5 has a clip-stop mechanism 6, and is configured to be fixed at a position rotated by 180 degrees within a horizontal plane.

A predetermined component, in this embodiment, a jig 7 to which a lead wire is supplied is placed and fixed on the rotary table 5. A plurality of rows of component receiving holes 8 are formed in the jig 7, and the pitch in the width direction between adjacent component receiving holes 8 in the same row is approximately half that of the conventional pitch. In this example, the pitch in the width direction is approximately 4.1 mm.

Note that the pitch between each row is the same as the conventional one.

In addition, in this embodiment, the number of component receiving holes 8 is 27 rows with 66 holes in each row, so the total number of component receiving holes 8 is 27.
There are 1782 pieces.

A male threaded shaft 8 is attached to one end of the movable table 3, and this shaft 8 has the following features:
One end thereof is screwed onto the rotating body 9. That is,
The rotating body 9 has a female thread cut on its inner peripheral surface, one end of the shaft 8 is screwed into the female thread, and is rotatably supported by an external member (not shown).

The rotating body 9 is connected to the output shaft of a motor 11 via a belt 10, and is configured to rotate by a predetermined angle as the motor 11 rotates.

On the other hand, a rotary shaft 12 extending vertically downward is provided on the bottom surface of the rotary table 5, and an output shaft 1 of a motor 13 is inserted into a recess formed at the end of the rotary shaft 12.
The protrusion member 15 attached to 4 is configured to fit together. Therefore, when a predetermined command is input to this motor 13, it rotates by 1/2, and this rotation is transmitted to the rotating shaft 12 via the protruding member 15, thereby rotating the rotary table 180 degrees. Become.

A plurality of component insertion guides 16 are provided in the width direction for supplying components such as lead wires to the jig 7, and are provided with a predetermined gap with respect to the component receiving hole 7a of the jig 7. Supported vertically.

The component insertion guide 16 is connected to a component supply device (not shown), and components are automatically supplied from the component supply device to the component supply port 16a of the component insertion guide 16.

Next, the operation of the component insertion device configured as described above will be explained.

Now, when the jig 7 placed on the rotary table 5 on the movable table 3 is at the start position indicated by the chain line at the right end of FIGS.
A component supply port 16a of the component insertion guide 16 located vertically above the column component receiving hole 7a.
Lead wires are supplied as parts. In this case, the pitch in the width direction of the component receiving holes 7a of the jig 7 is 1/2 pitch with respect to the pitch of the plurality of component supply ports 16a provided in the width direction, so every other component receiving hole is A lead wire will be supplied to 7a.

When the lead wires are completely supplied to the component receiving holes 7a in the first row, the motor 11 rotates by a predetermined angle, and this rotation is caused by the rotation body 9 via the belt 10.
Since the rotary body 9 has a female thread, the shaft 8, which is screwed into the female thread and has a male thread, is moved by a predetermined distance, and as a result, one end of the shaft 8 is The attached moving table 3 is moved to the left as shown in the figure. In this case, the motor 11 is controlled so that the moving table 3 is moved intermittently one pitch at a time in accordance with the pitch between adjacent rows of component receiving holes 7a provided in the jig 7. .

When the lead wires are supplied from the first row to the last n rows as described above, the moving table 3
It will move to the position indicated by the solid line in FIGS. 1 and 2, and at this position, the recess provided at one end of the rotating shaft 12 and the protrusion member 15 attached to the output shaft 14 of the motor 13 fit together, as shown in the figure. A rotation command is given to the motor 13 by a control signal from the omitted control device, and the motor 13 rotates by 1/2. This 1/2 rotation of the motor 13 is transmitted to the rotating shaft 12 via the protruding member 15, and the rotating table 5 fixed to the rotating shaft 12 is rotated. Rotate tool 7 180 degrees.

Next, the motor 1 is controlled by a command signal from the control device.
1 rotates in the opposite direction to return the movable table 3 to its initial position.

Therefore, in the jig 7 placed on the rotary table 5 on the moving table 3, the last row of the component receiving holes 7a is
It is arranged to be located directly below the component supply port 16a of the insertion guide 16 which is the starting position, and the nth row is the first row for the component receiving holes 8 that are not inserted every other pitch in the width direction. 1 to column
Lead wires are sequentially supplied to each column.

After the lead wires are supplied to the entire jig 7 without any gaps through the above operations, the jig 7 is removed from the rotary table 5 and sent to the next process.

In addition, in the above embodiment, the component insertion guide 16
Although the description has been made for the case where the parts supplied from the above are lead wires, the present invention is of course not limited to lead wires, and can be implemented in the same manner with other parts.

[Effect of the invention] As is clear from the above explanation, this invention has the following effects:
Components are fed into every other component receiving hole in the width direction of the component receiving holes provided in the jig, and after feeding them sequentially from the first row to the last row, the jig is turned over 180 degrees. Since the components are sequentially supplied to the remaining component receiving holes in the same manner as described above, conventionally, the number of components to be supplied onto the jig is limited due to width direction pitch restrictions due to the structure of the component insertion guide. However, the limited number of parts can be doubled, and by increasing the number of parts receiving holes, it is possible to perform mass processing in subsequent processes, and it has excellent effects such as improving production efficiency.
