Description

The present invention relates to leaded parts widely used in OA, home appliances, automobiles, etc., including the electronics field, and particularly to an alignment device in the manufacture of small leaded parts used in wristwatches, portable electronic devices, and the like.

For example, a wristwatch movement has a substrate mounted on it, and an electronic circuit and a small crystal unit for creating an accurate time reference signal. The crystal oscillator used here has a structure in which a crystal piece is joined to an airtight terminal having two reeds and airtightly sealed with a sealing tube. For example, the diameter is 1.5 mm and the length is 5.0 mm. It has a tubular outer shape, and two thin metal wires are used for the lead. In the manufacture of such a small crystal unit having a reed, in order to improve the accuracy of the oscillation frequency of the crystal, it is necessary to set the bonding position of the crystal piece with respect to the airtight terminal to a predetermined accuracy.

In response to such a requirement, a holder having an insertion hole is used as a carrier jig, and a lead of an airtight terminal (hereinafter referred to as a lead-attached part) of a crystal oscillator is inserted into the insertion hole of the holder. Furthermore, by positioning and holding the leaded component at the counterbore, the position accuracy of the leaded component with respect to the holder is improved, and then the crystal pieces previously positioned on the holder are joined and the sealing tube is press-fitted. A manufacturing method has been proposed. (See, for example, Patent Document 1.).

The prior art shown in Patent Document 1 uses a holder as a carrier jig until the final process of completing the crystal oscillator, and makes improvements so as to satisfy the following requirements. These include (1) holding the lead-attached part with high accuracy to the holder, and (2) preventing deformation and breakage when the sealing tube is press-fitted into the lead-attached part.

In the conventional technique, in the holder configuration, a holding portion in which a counterbore portion for positioning and holding a part with a lead is formed and a pedestal portion in which an insertion hole (through hole) for inserting a lead is formed. Although it was integrally composed of a resin material, for example, a metal material was used for the holding portion and an elastic resin material was used for the pedestal portion to form a two-body structure. As a result, it was possible to reduce the wear of the counterbore portion due to contact with the reed-attached part, and at the same time, it was possible to disperse the stress at the time of press-fitting the sealing pipe into the airtight terminal by utilizing the elasticity of the pedestal portion.

As described above, the prior art has made it possible to hold the parts with leads with high accuracy to the holder and use them repeatedly, and it has been possible to provide the effect of reducing the jig cost. Further, due to the elastic effect of the pedestal portion, it was possible to prevent deformation and breakage in the press-fitting of the sealing tube into the lead-attached part and provide an improvement in the manufacturing yield.

JP-A-2009-88752 (Page 1, FIG. 1)

However, in the prior art shown in Patent Document 1, a new problem has arisen in which the insertion rate is poor and the yield is lowered in the step of inserting the lead of the lead-attached part into the insertion hole of the holder. Although the prior art does not specifically describe the problem of insertion, the problem of inserting a lead will be described here. Generally, when inserting parts with leads, a process is adopted in which parts with leads are aligned using a parts feeder as an automatic feeder, picked up sequentially from the first part using a pickup head, and inserted into the insertion hole of the holder. However, the problems will be described below together with the main parts of the process related to the insertion failure.

FIG. 10A shows a chute 45 (alignment portion) of the parts feeder in the conventional alignment device, and shows a state in which the parts 1 with leads are aligned. The leading part with a lead 1a is separated, and the lead 4b on the insertion side (hereinafter referred to as an outer lead) is placed downward and held at a predetermined position of the separation holding device 47 (broken line portion) to wait for pickup. There is. Here, a predetermined amount of terminals 1 with leads are thrown into a ball (not shown) of the parts feeder, sequentially align their postures, travel in the direction of arrow A, and align with the chute 45 (1b, 1c, 1d to 1n). It has become like. Next, FIG. 10B shows a cross section of KK'of FIG. 10A, and is an enlarged display of a state in which the outer leads 4b are aligned with the guide groove 46. Here, with respect to the diameter d of the outer lead 4b, the width t0 of the guide groove 46 adds a margin α to smooth the running of the lead-attached component 1. This margin α causes an inclination (for example, θ1 or θ2) of the lead-attached component 1 in the rotation direction, which causes a lead insertion failure. On the other hand, in FIG. 10A, when the leaded component 1a held by the separation and holding device 47 is picked up, the next leaded component 1b is separated in the B direction and held by the separation and holding device 47. Then, the inclination in the rotation direction is not eliminated.

FIG. 11A shows a state immediately before the lead-attached component 1 (1a in FIG. 10) is picked up by the pickup head 40 (hereinafter, referred to as a detachable member). The detachable member 40 moves in the direction of arrow C (downward) and attracts the lead-attached component 1 by the suction portion 41 (at this time, a negative pressure due to air is applied to the suction hole 42). Next, the detachable member 40 moves in the direction of arrow C'(upward direction) and then in the direction of arrow D (horizontal direction). FIG. 11B shows a state immediately before the outer lead 4b of the lead-attached component 1 is inserted into the insertion hole 11b of the holder 11 by the detachable member 40. Next, the detachable member 40 moves in the direction of arrow E (downward) and inserts the lead-attached component 1 to a predetermined position. Next, the detachable member 40 moves in the direction of arrow E'(upward), and then returns to the position shown in FIG. 11 (a).

12 (a) shows the LL'cross section of FIG. 11 (b), and FIG. 12 (b) shows the MM' cross section of FIG. 12 (a). Here, FIGS. 12A and 12B show a state in which the outer leads 4b and the insertion holes 11b are aligned (hereinafter, referred to as alignment). Therefore, lead insertion failure does not occur here. Next, FIG. 12 (c) similarly shows the LL'cross section of FIG. 11 (b), and FIG. 12 (d) shows the NN' cross section of FIG. 12 (c). Here, in FIG. 12C, the position of the outer lead 4b is inclined, for example, θ1 in the rotation direction with respect to the insertion hole 11b. Therefore, in FIG. 12D, a deviation β between the insertion hole 11b and the outer lead 4b occurs. In this way, if the part 1 with a lead has an inclination θ1 in the rotation direction, alignment is poor, and when the outer lead 4b is inserted in that state, the tip of the outer lead 4b comes into contact with the surface of the counterbore portion 11a of the holding portion 11c to push and bend the lead. It will end up.

In order to reduce such insertion defects, a chamfered portion 11e is provided at the entrance of the insertion hole 11b of the holder 11 (see FIGS. 12B and 12D) so that the insertion hole and the outer lead 4b are displaced β. A method of absorbing the lead can be considered, but the effect cannot be obtained depending on the magnitude of the inclination of the lead-attached component 1 in the rotation direction. Further, as shown in FIG. 10B, in the chute 45 of the parts feeder, the width t0 of the guide groove 46 that guides the outer lead 4b is reduced (the margin α is reduced) to align the outer lead 4b. Although improvement is conceivable, the running resistance of the lead-attached component 1 increases due to variations or deformations in the outer diameter of the outer lead 4b, and new problems such as clogging or stopping at the chute 45 occur.

As described above, in the prior art shown in Patent Document 1, the holder is used as a carrier jig, the outer lead of the part with a lead is inserted into the insertion hole, and the part with a lead is positioned and held by the counterbore portion. Although it has made it possible to improve the position accuracy of the lead, it is not possible to solve the new problem of lead insertion failure due to misalignment of the lead-attached part with respect to the holder insertion hole.

[Explanation of operation of alignment control unit 60: FIG. 4]
FIG. 4 shows the positioning operation of the lead-attached component 1 in the rotation direction in the alignment control unit 60, and shows the QQ'cross section of FIG. 3 (b) in an enlarged manner. FIG. 4A shows a state before the rotation control claw 31 is operated by inserting the lead-attached component 1 into the alignment control unit 60. FIG. 4B shows a state when the rotation control claw 31 operates and comes into contact with the outer lead 4b. FIG. 4C shows a state in which the rotation control claw 31 continues to operate and positions the reed.

First, in FIGS. 4A and 4B, the leaded component 1 is received by the inclined surface 23 of the mortar-shaped guide portion 21 of the holding member 20, and the outer peripheral portion of the stem 2 of the leaded component 1 is the inclined surface 23. It is in a state of being guided and held by (see FIG. 3). In this state, the rotating shaft 9 of the lead-attached component 1 is stopped so as to coincide with the central axis of the mortar-shaped guide portion.

In FIG. 4A, the two outer leads 4b of the lead-attached component 1 are rotated by θ1 about the rotation axis 9 of the lead-attached component 1 and are in a state of poor alignment. The large circle (dashed line) indicates the part 1 with a lead, and the small circle (dashed line) indicates the through hole 22 formed in the holding member 20. The two rotation control claws 31 are in the standby position before operating toward the rotation shaft 9 (in the H direction). Further, the confrontation distance t2 between the two tip portions 33 facing each other is adjusted to a predetermined dimension in consideration of the fluctuation width (variation) of the inclination angle θ1 of the outer lead 4b. Further, a part of the chamfered portion 32 of the rotation control claw 31 is visible from the through hole 22 (see the shaded portion 32a). As a result, for example, even when the inclination angle θ1 of the outer lead 4b is larger than the drawing, the tip of the outer lead 4b is guided toward the center by the chamfered portion 32 (32a), so that insertion failure does not occur.

Next, in FIG. 4B, the two rotation control claws 31 operate toward the rotation shaft 9 (in the H direction), and their respective tip portions 33 are in contact with the outer lead 4b. At this time, the inclination angle of the outer lead 4b remains θ1. Further, the distance between the two tip portions 33 is narrowed from t2 to t2α. The two rotation control claws 31 further operate toward the rotation shaft 9 (in the H direction) to rotate the outer lead 4b in the f direction. At this time, as the outer lead 4b rotates, the outer peripheral portion of the lead-attached component 1 rotates in the f direction while sliding on the inclined surface 23 of the mortar-shaped guide portion 21.

Next, in FIG. 4C, the two rotation control claws 31 rotate the outer lead 4b in the f direction, and the inclination angle thereof changes from θ1 to θ2. Further, the distance between the two tip portions 33 is further narrowed from t2α to t2β. At this time, by adjusting the stop positions (t2β) of the two rotation control claws 31 so that 0 <θ2, the outer lead 4b can be positioned in the rotation direction without causing scratches or deformation due to pinching. It can be carried out. Further, after the positioning operation is completed, the two rotation control claws 31 may return to the confrontation position (H'direction) and stop at the confrontation distance t2 (see FIG. 4A). It is desirable that the rotation control claw 31 is stopped when the positioning operation is completed, and the lead-attached component 1 is picked up by the detachable member while the two rotation control claws 31 sandwich the outer lead 4b.

[Explanation of effect]
In the alignment device 100 of the first embodiment described above, the alignment control unit 60 of the leaded component 1 is provided at a predetermined position in the manufacturing process of the leaded component 1, and the leaded component 1 is guided by the mortar-shaped guide portion 21. In a state where the holding member 20 is rotatably held around a predetermined rotation axis, the holding member 20 can be sandwiched by a rotation control member composed of a pair of rotation control claws and positioned in the rotation direction. As a result, it is possible to improve the alignment of the leads of the lead-attached component, reduce the insertion failure of the lead of the lead-attached component into the holder insertion hole, and provide an improvement in the yield. Further, the alignment device 100 can be applied to lead-attached parts such as semiconductor elements, crystal oscillators, resistors and capacitors widely used in OA, home appliances, automobiles, wristwatches, portable electronic devices and the like.

The shape for holding the parts with leads is a mortar-shaped guide portion provided with an inclined surface, but the shape is not limited to this, and may be, for example, an inverted pyramid shape or another inverted pyramid shape. .. Further, it is desirable to control the inclination angle θ1 of the lead of the lead-attached component to be inserted into the alignment control unit to 60 ° or less, and more preferably to 45 ° or less. The reason is that when θ1 becomes, for example, 60 ° or more, the rotation of the two reeds by the rotation control claw is not performed smoothly, and the risk of pinching and crushing increases. Further, it is desirable that the gap u between the bottom surface of the holding member 20 and the rotation control claw 31 is a predetermined gap in consideration of the length of the outer lead 4b and the position where it is sandwiched. Further, as shown in FIG. 3C, the through hole provided at the bottom of the mortar-shaped guide portion 21 of the holding member 20a may be a long hole-shaped through hole 22a (width t4). With such an elongated hole shape, the rotation direction of the outer lead 4b is restricted when the lead-attached component 1 is inserted, so that the chamfered portion 32 provided on the rotation control claw 31 becomes unnecessary, and the structure can be simplified. When the chamfered portion 32 is abolished, it is desirable that the width t4 of the through hole 22a is set to t4 <t2 with respect to the distance t2 between the tip portions 33 of the rotation control claws 31 (lead tip and rotation control). To prevent the claws 33 from coming into contact with each other).

Here, although not particularly limited, the main materials used for the holding member 20 and the rotation control claw 31 of the alignment control unit 60 will be listed. For example, it is a metal material such as SUS or Fe, a resin material such as POM or Nylon, or a composite of a metal material and a resin material. The area of contact with the leaded component 1 such as the surface of the inclined surface 23 of the holding member 20 and the surface of the rotation control claw 31 is coated with diamond-like carbon, for example, to form the stem 2 of the leaded component 1 or the like. The frictional resistance with the lead 4 can be reduced.

[Explanation of Alignment Control Unit 61: FIG. 5]
Next, the alignment control unit 61 will be described with reference to FIG. FIG. 5A shows a cross-sectional view (corresponding to FIG. 3B) of the alignment control unit 61. FIG. 5B shows a perspective view of the holding member 20b having the round hole-shaped through hole 22, and FIG. 5C shows a perspective view of the holding member 20c having the elongated hole-shaped through hole 22a. Further, FIG. 5D shows a cross-sectional view of a holding member 20d in which a step portion 24 is provided with a guide shape by a tubular portion 25.

The feature of the alignment control unit 61 is that by providing a step portion 24 on the mortar-shaped guide portion of the holding member 20 which is a component of the alignment control unit, more reliable positioning in the direction intersecting the rotation axis of the lead-attached component 1 can be performed. This is the point that made it possible. Since the basic configuration of the alignment control unit 61 is the same as that of the alignment control unit 60, the same elements are designated by the same reference numerals and duplicate description will be omitted.

In FIG. 5A, the holding member 20b constituting the alignment control unit 61 has a mortar-shaped guide portion 21 formed by an inclined surface 23, similarly to the holding member 20 described above. Further, the mortar-shaped guide portion 21 is provided with a step portion 24 at a predetermined distance s from the bottom surface of the holding member 20b, and has a through hole 22 (diameter t1) at the center thereof. The diameter t5 of the step portion 24 is set to a value slightly larger than the outer diameter of the stem 2 of the lead-attached component 1. FIG. 5B is a perspective view of the holding member 20b, and the shape of the stepped portion 24 formed on the mortar-shaped guide portion 21 is shown in an easy-to-understand manner.

By providing the step portion 24 on a part of the inclined surface 23 of the mortar-shaped guide portion 21 in this way, when the lead-attached component 1 is inserted into the holding member 20b by the detachable member 40, the step portion 24 is used as the positioning portion. The direction in which the lead-attached component 1 intersects the rotation axis 9 can be reliably positioned. As a result, positioning in the rotation direction by the rotation control claw 31 can be performed more accurately. As a result, it is possible to improve the alignment of the leads of the lead-attached component, reduce the insertion failure of the lead of the lead-attached component into the holder insertion hole, and provide an improvement in the yield.

The step portion 24 may be provided at an arbitrary position on the inclined surface 23. For example, it may be formed in the intermediate portion of the inclined surface 23, and the position thereof can be determined in consideration of the inclination angle of the inclined surface 23, the outer diameter of the part with a lead, and the like. Further, a plurality of stepped portions may be provided so as to support a plurality of parts with leads having different shapes. Further, it is desirable that the diameter t5 of the step portion 24 is set in consideration of the variation in the outer shape of the stem 2 of the lead-attached component 1. Further, the distance s from the bottom surface of the step portion 24 may be adjusted so as to sandwich a predetermined position of the outer lead 4b in consideration of the distance that the holding member 20b and the rotation control claw 31 can operate. Good. Although the through hole 22 is circular, it may be a through hole 22a having a long hole shape (width t4) as in the holding member 20c shown in FIG. 5 (c). When the elongated through hole 22a is adopted, the lead tip penetrates so as not to abut on the step portion 24 in consideration of the variation in the rotation direction angle θ1 of the outer lead 4b when the lead-attached component 1 is inserted. It is desirable to set the width t4 of the hole 22a. Further, as in the holding member 20d shown in FIG. 5D, a guide-shaped tubular portion 25 that rises in a tubular shape from the outer portion of the step portion 24 may be provided. By providing such a shape, the position accuracy of the leaded component 1 in the direction intersecting the rotation axis 9 can be further improved.

A feature of the alignment control unit 62 is that the rotation control claws 31 constituting the rotation control member 30 can accommodate the deformation of the reed by sandwiching the tip end side of the outer lead 4b. Since the basic configuration of the alignment control unit 62 is the same as that of the alignment control unit 60, the same elements are designated by the same reference numerals and duplicate description will be omitted.

In FIG. 6, the alignment control unit 62 differs from the above-mentioned alignment control unit 61 in that the distance r between the holding member 20b and the two rotation control claws 31 is large. As a result, the tip 33 of the rotation control claw 31 can sandwich the position close to the tip of the outer lead 4b of the lead-attached component 1. For example, when the tip side of the outer lead 4b is twisted or bent, for example, the tip 33 of the rotation control claw 31 has a rotation direction corresponding to the twist or bend of the two outer leads 4b. Positioning is performed and alignment is improved.

In this way, the alignment control unit 62 is positioned on the tip side of the two outer leads 4b in accordance with twisting and bending, so that the alignment on the tip side of the outer lead 4b is improved and the insertion accuracy is improved. Can be improved. As a result, it is possible to improve the alignment of the leads of the lead-attached component, reduce the insertion failure of the lead of the lead-attached component into the holder insertion hole, and provide an improvement in the yield.

It is desirable that the distance r between the holding member 20b and the rotation control claw 31 is set to a predetermined value in consideration of the length of the outer lead 4b of the lead-attached component 1 and the variation in deformation of the outer lead 4b. Further, the through hole 22 (diameter t1) formed in the bottom of the holding member 20b and the distance t2 between the tip portions 33 of the two rotation control claws 31 are also determined in consideration of the variation in deformation of the outer lead 4b and the like.
