Description

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

  For example, a wristwatch movement is equipped with a substrate, and an electronic circuit and a small crystal unit for generating an accurate time reference signal. The crystal resonator used here has a structure in which a crystal piece is bonded to an airtight terminal having two leads and hermetically sealed with a sealing tube. For example, the diameter is 1.5 mm and the length is 5.0 mm. In addition, two thin metal wires are used for the leads. In the manufacture of such a small crystal resonator having a lead, in order to increase the accuracy of the oscillation frequency of the crystal, it is necessary to make the bonding position of the crystal piece to the hermetic terminal within a predetermined accuracy.

  For such a demand, a holder with an insertion hole is used as a carrier jig, and a lead of a hermetic terminal of a crystal resonator (hereinafter referred to as a component with a lead) is inserted into the insertion hole of the holder. Furthermore, by positioning and holding the leaded parts at the counterbore, the positional accuracy of the leaded parts with respect to the holder is improved, and then the bonding of the crystal pieces that are pre-positioned to the holder and press-fitting of the sealing tube are performed. Proposed manufacturing methods have been proposed. (For example, refer to Patent Document 1).

  The prior art disclosed in Patent Document 1 uses the holder as a carrier jig until the final process for completing the crystal unit, and performs improvements so as to satisfy the following requirements. (1) Hold the leaded component with respect to the holder with high accuracy, (2) Prevent deformation and breakage in press-fitting the sealing tube into the leaded component, and the like.

  In the prior art, in the structure of the holder, a holding part in which a counterbore part for positioning and holding a leaded part has been formed and a pedestal part in which an insertion hole (through hole) for inserting a lead is formed. However, 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 wear due to contact between the counterbore part and the leaded part, and at the same time, using the elasticity of the pedestal part, the stress at the time of press-fitting the sealed tube into the hermetic terminal could be dispersed.

  As described above, the conventional technique can hold the leaded component with respect to the holder with high accuracy and can be used repeatedly, and can provide an effect of reducing jig cost. Further, due to the elastic effect of the pedestal, deformation and breakage can be prevented in press-fitting the sealing tube into the leaded component, and the manufacturing yield can be improved.

JP 2009-88752 A (first page, FIG. 1)

  However, in the prior art disclosed in Patent Document 1, a new problem has occurred that the insertion rate is poor and the yield is reduced in the process of inserting the lead of the leaded component into the insertion hole of the holder. Although the prior art does not particularly describe the problem of insertion, here, the problem of lead insertion will be described. In general, when inserting leaded parts, a part feeder is used as an automatic feeder to align the leaded parts, picking up from the first part using a pickup head, and inserting it into the holder insertion hole. However, the problem will be described below together with the main part of the process related to the insertion failure.

  FIG. 10A shows a chute 45 (alignment portion) of a parts feeder in a conventional alignment apparatus and shows a state in which the leaded parts 1 are aligned. The lead-attached component 1a is separated, and the lead 4b (hereinafter referred to as the outer lead) on the insertion side is kept downward and is held at a predetermined position of the separation holding device 47 (broken line portion) to wait for pickup. Yes. Here, a predetermined amount of the terminal 1 with lead is put into a ball (not shown) of a parts feeder, and the postures are sequentially aligned, travel in the direction of arrow A, and align with the chute 45 (1b, 1c, 1d to 1n). It is like that. Next, FIG. 10B shows the KK ′ cross section of FIG. 10A and shows an enlarged view of a state in which the outer lead 4 b is 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 traveling of the leaded component 1. This margin α causes a tilt in the rotational direction of the leaded component 1 (for example, θ1 or θ2), and therefore 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 tilt in the rotation direction is not eliminated.

  FIG. 11A shows a state immediately before the leaded 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 sucks the leaded component 1 by the suction portion 41 (at this time, negative pressure by air is applied to the suction hole 42). Next, the detachable member 40 moves in the direction of arrow C ′ (upward direction) and then moves in the direction of arrow D (lateral direction). FIG. 11 (b) shows a state immediately before the outer lead 4 b of the leaded component 1 is inserted into the insertion hole 11 b 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 leaded 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 of FIG.

  12A shows the LL ′ cross section of FIG. 11B, and FIG. 12B shows the MM ′ cross section of FIG. 12A. 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). Accordingly, no lead insertion failure occurs here. Next, FIG.12 (c) shows the LL 'cross section of FIG.11 (b) similarly, and FIG.12 (d) has shown 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. For this reason, in FIG. 12D, a deviation β between the insertion hole 11b and the outer lead 4b occurs. As described above, if the component 1 with the lead has a tilt θ1 in the rotational direction, the alignment is poor, and when inserted in this state, the tip of the outer lead 4b abuts against 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 failure, by providing a chamfered portion 11e at the entrance of the insertion hole 11b of the holder 11 (see FIGS. 12B and 12D), the displacement β between the insertion hole and the outer lead 4b can be reduced. Although a method of absorbing is conceivable, the effect cannot be obtained depending on the magnitude of the inclination in the rotation direction of the leaded component 1. Further, as shown in FIG. 10B, in the chute 45 of the parts feeder, the width t0 of the guide groove 46 for guiding the outer lead 4b is reduced (the margin α is reduced), thereby aligning the outer lead 4b. Although it is conceivable to improve, the running resistance of the leaded component 1 increases due to the variation or deformation of the outer diameter of the outer lead 4b, and a new problem such as clogging or stopping at the chute 45 occurs.

  As described above, the prior art disclosed in Patent Document 1 uses a holder as a carrier jig, inserts an outer lead of a component with a lead into an insertion hole, and further performs positioning and holding at a counterbore, thereby providing a component with a lead. However, it is impossible to solve the new problem of lead insertion failure due to poor alignment of the leaded parts with respect to the holder insertion hole.

At this time, the lead-equipped component 1 rotates in the f direction while the outer peripheral portion slides on the inclined surface 23 of the mortar-shaped guide portion 21 as the outer lead 4b rotates.

  Next, in FIG. 4C, the two rotation control claws 31 rotate the outer lead 4b in the f direction, and the inclination angle changes from θ1 to θ2. Further, the distance between the two tip portions 33 is further reduced from t2α to t2β. At this time, by adjusting the stop position (t2β) of the two rotation control claws 31 so that 0 <θ2, the positioning in the rotation direction can be performed without causing the outer lead 4b to be scratched or deformed. It can be carried out. In addition, the two rotation control claws 31 may return to the facing position (H ′ direction) and stop at the facing distance t2 (see FIG. 4A) after completing the positioning operation. It is desirable that the rotation control claw 31 is stopped after the positioning operation is completed, and the leaded component 1 is picked up by the detachable member while the two rotation control claws 31 hold the outer lead 4b. In the positioning operation in the rotational direction of the leaded component 1 described with reference to FIGS. 4A to 4C, the leaded component 1 is positioned using the inclined surface 23 of the mortar-shaped guide portion 21 as a positioning portion. The rotating shaft 9 of the leaded component 1 can be held at the center position of the mortar-shaped guide portion.

[Description of effects]
In the alignment apparatus 100 according to the first embodiment described above, the alignment control unit 60 for 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 mortar-shaped guide portion 21. In a state in which the holding member 20 provided with is rotatably held around a predetermined rotation axis, the holding member 20 can be sandwiched by a rotation control member including a pair of rotation control claws and positioned in the rotation direction. As a result, it is possible to improve the lead alignment of the leaded component, to reduce the defective insertion of the lead of the leaded component into the holder insertion hole, and to improve the yield. The alignment apparatus 100 can be applied to leaded components such as semiconductor elements, crystal resonators, resistors, capacitors, and the like widely used in OA, home appliances, automobiles, watches, portable electronic devices, and the like.

  The shape for holding the leaded component is a mortar-shaped guide portion having an inclined surface. However, the shape is not limited to this, and may be, for example, an inverted pyramid shape or another inverted cone shape. . Further, it is desirable to manage the inclination angle θ1 of the lead with the lead inserted into the alignment control unit to 60 ° or less, and more desirably to manage to 45 ° or less. The reason is that when θ1 is 60 ° or more, for example, the rotation of the two leads by the rotation control claw is not smoothly performed, and there is an increased risk of pinching and crushing. In addition, 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 clamping position. Moreover, as shown in FIG.3 (c), the through-hole provided in the bottom part of the mortar-shaped guide part 21 of the holding member 20a is good also as a long-hole-shaped through-hole 22a (width | variety t4). By adopting such a long hole shape, the rotation direction of the outer lead 4b is restricted when the lead-equipped component 1 is inserted, so that the chamfered portion 32 provided in the rotation control claw 31 is not necessary, and the structure can be simplified. When the chamfered portion 32 is abolished, the width t4 of the through hole 22a is desirably set to t4 <t2 with respect to the distance t2 between the tip portions 33 of the rotation control claw 31 (lead tip and rotation control). (For prevention of contact of the nail 33).

  Here, although not particularly limited, main materials used for the holding member 20 and the rotation control claw 31 of the alignment control unit 60 are listed. For example, 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. It should be noted that the regions such as the surface of the inclined surface 23 of the holding member 20 and the surface of the rotation control claw 31 that are in contact with the leaded component 1 are coated with, for example, diamond-like carbon so that the stem 2 of the leaded component 1 The frictional resistance with the lead 4 can be reduced.

[Description of Alignment Control Unit 61: FIG. 5]
Next, the alignment control unit 61 will be described with reference to FIG. FIG. 5A shows a sectional view of the alignment control unit 61 (corresponding to FIG. 3B). 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 long hole-shaped through hole 22a. FIG. 5D shows a cross-sectional view of the holding member 20 d in which the stepped portion 24 is provided with a guide shape by the tubular portion 25.

  A feature of the alignment control unit 61 is that a stepped portion 24 is provided in the mortar-shaped guide portion of the holding member 20 that is a component of the alignment control unit, thereby achieving more reliable positioning in the direction intersecting the rotation axis of the leaded component 1. This is what 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 components are denoted by the same reference numerals, and redundant description is omitted.

  5A, in the holding member 20b constituting the alignment control unit 61, the mortar-shaped guide portion 21 is formed by the inclined surface 23, similarly to the holding member 20 described above. The mortar-shaped guide portion 21 includes 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 leaded component 1. FIG. 5B is a perspective view of the holding member 20b, and illustrates the shape of the stepped portion 24 formed in the mortar-shaped guide portion 21 so as to be easily understood.

  Thus, by providing the stepped portion 24 on a part of the inclined surface 23 of the mortar-shaped guide portion 21, when the leaded component 1 is inserted into the holding member 20b with the detachable member 40, the stepped portion 24 is used as a positioning portion. The direction that intersects the rotating shaft 9 of the leaded component 1 can be reliably positioned. Thereby, 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 lead alignment of the leaded component, reduce the defective insertion of the lead of the leaded component into the holder insertion hole, and improve the yield.

  The step portion 24 may be provided at an arbitrary position on the inclined surface 23. For example, you may form in the intermediate part of the inclined surface 23, and the position can be determined in consideration of the inclination angle of the inclined surface 23, the outer diameter of components with leads, and the like. Further, a plurality of stepped portions may be provided so that a plurality of leaded parts having different shapes can be accommodated. Moreover, it is desirable to set the diameter t5 of the step portion 24 in consideration of variations in the outer shape of the stem 2 of the leaded component 1. Further, the distance s from the bottom surface of the stepped portion 24 may be adjustable so as to sandwich the 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. Moreover, although the through-hole 22 was circular, it is good also as a through-hole 22a of long hole shape (width | variety t4) like the holding member 20c shown in FIG.5 (c). When the long hole-shaped through hole 22a is employed, the lead end of the lead does not come into contact with the step portion 24 in consideration of the variation in the angle θ1 in the rotation direction of the outer lead 4b when the leaded 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 cylindrical portion 25 that rises in a cylindrical shape from the outer side of the stepped portion 24 may be provided. By providing such a shape, it is possible to further improve the positional accuracy in the direction intersecting the rotating shaft 9 of the leaded component 1.

[Description of Alignment Control Unit 62: FIG. 6]
Next, the alignment control unit 62 will be described with reference to FIG. FIG. 6 is a cross-sectional view of the alignment control unit 62.

  The feature of the alignment control unit 62 is that the rotation control claw 31 constituting the rotation control member 30 can support the deformation of the lead by sandwiching the distal 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 denoted by the same reference numerals, and redundant description is omitted.

  In FIG. 6, the alignment control unit 62 is different from the alignment control unit 61 described above in that the distance r between the holding member 20 b and the two rotation control claws 31 is large. Thereby, the front-end | tip part 33 of the rotation control nail | claw 31 can clamp the position near the front-end | tip of the outer lead 4b of the components 1 with a lead. For example, in the case where, for example, twisting or bending occurs on the distal end side of the outer lead 4b, the distal end portion 33 of the rotation control claw 31 rotates in a direction corresponding to the twisting or bending of the two outer leads 4b. Positioning is performed and alignment is improved.

  As described above, the alignment control unit 62 performs positioning corresponding to twisting and bending at the distal end side of the two outer leads 4b, so that alignment at the distal end side of the outer lead 4b is improved and insertion accuracy is improved. Can be improved. As a result, it is possible to improve the lead alignment of the leaded component, to reduce the defective insertion of the lead of the leaded component into the holder insertion hole, and to improve the yield.

  The distance r between the holding member 20b and the rotation control claw 31 is preferably set to a predetermined value in consideration of the length of the outer lead 4b of the leaded component 1 and variations 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 interval t2 between the tip portions 33 of the two rotation control claws 31 are also determined in consideration of variations in deformation of the outer lead 4b. It is desirable to set this position.
