Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pin shaping device for shaping the bending of pins of parts having a plurality of pins, such as small transformers and coils.

Generally, when mounting and soldering parts such as small transformers, coils, and IC packages that have multiple wiring pins to a wiring board, it may be difficult to mount them onto the wiring board if each pin is bent. Become.
On the other hand, if the pin mounting hole on the wiring board is made large so that the pin can be mounted on the wiring board even if the pin is bent, the gap between the pin mounting hole and the pin will become larger when the pin is not bent. Since this gap is supported only by solder, there is a problem in terms of strength, and the mounting hole cannot be made larger. For this reason, a shaping process to correct the bending of the pins of the component is essential, and some type of pin shaping device is used for shaping.

The conventional pin shaping method uses a pair of plate-shaped positioning jigs with a V-shaped shallow groove at one end.
Place this pair of jigs one by one with the pin in between, and
The position is slightly shifted in the axial direction of the pin,
In this state, press a pair of jigs toward the pin and
A method of holding a pin in a shape groove and shaping it by this,
Alternatively, you can use a gauge plate that allows holes to be drilled at the appropriate pitch in a position facing the pin, and the pin insertion side of the hole is chamfered by smooth machining.
A method of shaping the gauge plate by simply inserting pins into each hole was used.

However, these conventional methods have the disadvantage that perfect shaping is not always possible.

An object of the present invention is to provide a pin shaping device that can reliably shape the pins of a component to be shaped, such as a transformer, having a plurality of pins.

The present invention supports the part to be shaped on a component support member, inserts each pin of the part to be shaped into the pin hole of the shaping member, and eccentrically moves these parts to be shaped and the component support member by an eccentric movement mechanism. The purpose of this invention is to achieve the above object by shaping the pin.

Hereinafter, embodiments of the present invention will be described based on the drawings.

A first embodiment of the present invention is shown in FIGS. 1 to 3, with the overall structure shown in FIGS. 1 and 2, and a cross section of the main parts shown in FIG.

In FIGS. 1 and 2, a slider receiver 2 is fixed within a frame 1, and guides 3 are provided on both longitudinal edges of the upper surface of the slider receiver 2, respectively.
A first slider 4 is supported between these guides 3 so as to be slidable on the slider receiver 2 in the left-right direction in FIGS. 1 and 2, that is, in the direction of arrow X.

As shown in FIG. 1, the first slider 4 is formed into a substantially U-shaped cross section with an open upper part, and inside this U-shape, a second slider 5 is arranged perpendicular to the plane of the paper in FIG. It is housed so as to be slidable in the vertical direction in FIG. 2, that is, in the direction of arrow Y.
As shown in FIG. 1, this second slider 5 is also formed in a substantially U-shaped cross section with an open upper part, and an eccentric hole 5A is formed in the bottom surface, and an eccentric hole 5A is formed in the eccentric hole 5A. Cam 6 has no play, and
Rotatably fitted. An output shaft 8A of a motor 8 serving as a drive source is fixed to the eccentric cam 6, and extends through through holes 4A and 2A provided in the first slider 4 and the slider receiver 2.
As a result, the second slider 5 moves eccentrically as the eccentric cam 6 rotates. These slider receiver 2, guide 3, first slider 4, second slider 5, and eccentric cam 6 constitute an eccentric movement mechanism 7.

An actuating member 9 is fixed in the middle of the output shaft 8A of the motor 8, and a micro switch 10 operated by the actuating member 9 is fixed to the lower surface of the slider receiver 2. 10 constitutes a rotation detection mechanism 11, which is capable of stopping the motor 8 when the output shaft 8A rotates once.

A plate-shaped shaping member 12 is removably attached to the upper opening of the second slider 5 with screws 13 . As shown in an enlarged view in FIG. 3, this shaping member 12 includes a plurality of pin holes 12A into which a plurality of pins 15 provided on a part to be shaped 14 such as a transformer can be inserted. These pin holes 12A have a pitch P between each hole equal to the pitch of the pin 15 of the part to be shaped 14, a hole diameter D slightly larger than the diameter of the pin 15, and a pin 15 of the pin hole 12A. A chamfered portion 12B is formed on the insertion side of the pin 1 by smooth machining.
5 can be inserted even if it is slightly bent.

A thick plate-shaped component support member 16 is removably attached to the upper part of the frame 1 with bolts 17 . This component support member 16 has a through hole 16A.
is formed, and the part to be shaped 14 is supported by this through hole 16A.

In such a configuration, in order to shape the pin 15 of the part to be shaped 14, the pin 1 of the part to be shaped 14 is
A shaping member 12 having a pin hole 12A corresponding to 5.
is attached to the second slider 5 in advance, and in this state, the part to be shaped 14 is inserted into the through hole 16A of the component support member 16 from the pin 15 side, and the pin 15 is inserted into the pin hole 12A of the shaping member 12. Insert it and hold it in this state by pressing it from above with your hand or a jig.

Next, when a start switch (not shown) is operated to drive the motor 8, the eccentric cam 6 rotates as the output shaft 8A rotates, and the first slider 4
In the Y direction, the second slider 5 slides in accordance with the eccentricity of the eccentric cam 6, respectively. For this reason,
The second slider 5 makes an eccentric movement as a combined movement with the first slider 4, and this second slider 5
The shaping member 12 fixed to the slider 5 also makes an eccentric movement. At this time, the amount of eccentricity of the eccentric cam 6 varies depending on the type of the part to be shaped 14, but usually
A thickness of about 0.5 to 1.0 mm is sufficient.

On the other hand, since the part to be shaped 14 is fixedly supported by the part support member 16, only the pin 15 is moved eccentrically, and the bending etc. is corrected by the eccentric movement of the pin 15. .

In this way, the shaping member 12 is eccentrically moved by the eccentric cam 6, and when the eccentric cam 6 makes one revolution, the micro switch 10 is actuated by the operating member 9, and the motor 8 is automatically stopped. At this time, if one rotation of the eccentric cam 6 is not sufficient for shaping, press the start switch again or change the structure of the rotation detection mechanism 11 to
The micro switch 10 is activated by multiple rotations of the rotating shaft 8A, or the power circuit of the motor 8 is cut off by multiple signals from the rotation detection mechanism 11. Good too.

The part to be shaped 14 that has been completely shaped is removed, replaced with the next part 14 and operated in the same manner, and shaping is performed in sequence.

According to this embodiment, the shaping member 12 is eccentrically moved by the eccentric movement mechanism 7 consisting of the sliders 4 and 5 that are slidable in the cross directions of X and Y, the eccentric cam 6, etc., and the shaping member 12 is moved eccentrically. Since the pin 15 of the part to be shaped 14 inserted into the pin hole 12A is moved eccentrically, the pin 15 can be shaped reliably. Moreover, since it is only necessary to insert the pin 15 into the pin hole 12A of the shaping member 12 and operate the start switch of the motor 8, the operation is easy and the work efficiency can be improved.

In this embodiment, the pins 15 of different types of parts to be shaped 14 can be shaped by replacing the shaping member 12 and the component support member 16 as appropriate.

FIG. 4 shows the main parts of a second embodiment of the present invention. Here, the same or equivalent components as in the first embodiment are designated by the same reference numerals. In this embodiment, the eccentric movement mechanism 7 is simplified, and the shaping member 12 is directly driven by the eccentric cam 6.

That is, in FIG. 4, a plurality of pin holes 12A having chamfered portions 12B are formed in the shaping member 12, and an eccentric hole 12C is formed in the center, and a motor (not shown) is formed in the eccentric hole 12C. The eccentric cam 6 fixed to the output shaft 8A is fitted without play. The peripheral edge of this shaping member 12 is supported by a guide member 18 so as to be able to eccentrically move within a horizontal plane. This guide member 18 is provided with a lid member 18A, and this lid member 18A is made removable with a screw 19, thereby making the shaping member 12 replaceable. Further, the eccentric cam 6,
The shaping member 12 and the guide member 18 constitute an eccentric movement mechanism 7.

Also in this embodiment configured in this way, the shaping member 12 can be moved eccentrically by rotating the output shaft 8A, and therefore, the component support member 16 attached to the frame 1 with the bolt 17 can penetrate. By inserting a pin of a part to be shaped (not shown) supported by the hole 16A into the pin hole 12A of the shaping member 12 and moving the shaping member 12 eccentrically, the pin can be easily shaped. Moreover, since the structure is simple, it can be provided at low cost.

In each of the above embodiments, the shaping member 12 is moved eccentrically by the eccentric movement mechanism 7, but in practice, the shaping member 12 side may be fixed and the component support member 16 side may be moved eccentrically. The eccentric movement mechanism 7 may cause the shaping member 12 and the component support member 16 to move eccentrically relative to each other. Also,
The eccentric movement mechanism 7 is not limited to the configuration of each of the embodiments described above, but may have other configurations, and the drive source of the eccentric movement mechanism 7 is not limited to the motor 8, but may also include other structures such as one using a combination of a rack and a pinion and a cylinder. It may be a configuration.
Furthermore, in each of the above embodiments, the component support member 16 simply supports the shaped component 14 through the through hole 16A, but the component support member 16 is separated into left and right sides,
Slide these left and right members using a cylinder etc.
The part to be shaped 14 may be held between these left and right members. Moreover, the micro switch 10 of the rotation detection mechanism 11 may also be a switch such as a reed switch.

As described above, the present invention has the effect of providing a pin shaping device that can easily and reliably shape the pins of a part to be shaped.
