Description

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

For example, a wristwatch movement has a substrate mounted on it, which mounts an electronic circuit and a small crystal unit to create an accurate time reference signal. The crystal oscillator used here has a structure in which a crystal piece is joined to an airtight terminal provided with 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 to be carried out 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 prior art, 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. It was integrally composed of a resin material, but 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 reliably hold the lead-attached part with respect to the holder and use it 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 during press-fitting of the sealing tube into the part with a lead, and to provide an improvement in the manufacturing yield.

Japanese Unexamined Patent Publication No. 2009-88752 (Page 1, FIG. 1)

However, in the prior art shown in Patent Document 1, the position accuracy of the lead on the crystal piece bonding side (hereinafter referred to as the inner lead) is not sufficient, and the bonding position between the inner lead and the crystal piece is set to a predetermined accuracy. There was a new challenge of not being able to do it. In addition, there is a problem that the insertability is poor and the yield is lowered in the process of inserting the lead on the insertion side of the part with a lead (hereinafter, referred to as an outer lead) into the insertion hole of the holder. Although these problems are not specifically described in the prior art, two problems will be described here.

Here, in FIG. 1 of Patent Document 1, the manufacturing method of the crystal oscillator 10 is described in a schematic diagram, which will be reprinted in FIG. 14 to explain their problems. In FIG. 14, generally, in order to insert the leaded component (airtight terminal) 1 into the holder 11, a parts feeder (automatic supply device for components (not shown)) is used, and the leaded component 1 is inserted into the chute (alignment portion) of the parts feeder. ), Picked up from the first component in sequence using the pickup head, and inserted into the insertion hole 11b of the holder 11. At this time, in order to maintain the runnability of the lead-attached component 1, it is necessary to add a margin to the width of the groove of the chute to make it wider than the diameter of the outer lead 4b. This is because the leads of the component 1 with leads include variations in diameter, deformation, and the like. On the other hand, the margin of the groove width of the chute causes variation in the rotation direction of the lead-attached component 1, so that a factor that causes a positional deviation of the lead-attached component 1 in the rotation direction when picking up and inserting the lead-attached component 1 into the holder 11. become. As a result, the positions of the outer leads 4b in the rotation direction may not be aligned with the insertion holes 11b of the holder 11 (hereinafter, referred to as poor alignment), and the tip of the outer leads 4b is the counterbore portion 11a of the holding portion 11c. It comes into contact with the bottom surface of the lead and pushes and bends the lead. In order to reduce such insertion defects, it is conceivable to provide a chamfered portion at the entrance of the insertion hole 11b of the holder 11 to absorb the deviation between the insertion hole 11b and the outer lead 4b. The effect cannot be obtained depending on the size of the displacement in the rotation direction of.

On the other hand, the part 1 with a lead, which has a small misalignment and allows the outer lead 4b to be inserted into the insertion hole 11b, is further inserted in that state, and the outer circumference of the stem 2 fits into the inner circumference of the counterbore portion 11a. And be retained. However, the misalignment in the rotational direction that occurs in the chute of the parts feeder is maintained even after press fitting. The misalignment in the rotational direction maintained even after press-fitting reduces the accuracy of the joint position between the inner reed 4a and the crystal piece 5 when the inner reed 4a and the crystal piece 5 are joined in the subsequent process, and the crystal It becomes difficult to stabilize the characteristics of the oscillator.

In the prior art shown in Patent Document 1, by using the holder as a carrier jig and using a metal material for the holding portion 11c, it was possible to improve the positioning accuracy and the durability of the holder. However, it is not possible to solve the problem that it is difficult to improve the accuracy of the joint position between the inner reed and the quartz piece, which is related to the stabilization of the characteristics which are particularly important for the crystal oscillator. Further, the problem of poor reed insertion caused by poor alignment of the outer reed of the part with a reed with respect to the insertion hole of the holder cannot be solved.

Therefore, an object of the present invention is to solve the problem that it is difficult to improve the accuracy of the joint position between the inner lead and the element among the above problems, and it is an alignment device for parts with leads.

It is composed of a lead rotation control means 30, and a component 1 with a lead is inserted and held in the center of a mortar-shaped guide portion 21 of a holding member 20 with the inner lead 4a facing upward and the outer lead 4b facing downward. It shows the state that was done. FIG. 2A shows a state in which the part 1 with a lead is guided to the center of the mortar-shaped guide portion 21 and is positioned in the horizontal direction.

In FIG. 2B, the holding member 20 is made of, for example, a SUS material, has a mortar-shaped guide portion 21 (recessed portion) in the central portion, and the mortar-shaped guide portion 21 is formed by an inclined surface 23 toward the center thereof. ing. Further, a through hole 22 (diameter t1) is formed at the bottom.

It is arranged so as to face each other with respect to the center of the mortar-shaped guide portion 21, and moves toward the center with a predetermined accuracy (H direction) and moves away from each other with a predetermined accuracy (H'direction). You can do it. Further, the amount of movement of the pair of outer lead rotation control claws 31 toward the center of the mortar-shaped guide portion 21 of the holding member 20 can be adjusted to optimally position the outer lead 4b in the rotation direction, and the lead It is designed so that it will not be scratched by being pinched. In addition, here, the other mechanical part, the driving part, the frame body part and the like constituting the alignment control part 50 are not shown.

The inner reed 4a is inserted at an angle of θ1 about the inner reed rotation shaft 9a (as an example of poor alignment) (see FIG. 2A). Further, the outer lead 4b is inserted toward the center of the mortar-shaped guide portion 21 of the holding member 20 around the outer lead rotation shaft 9b so that the outer lead 4b can pass through the through hole 22. Then, the outer peripheral portion of the stem 2 of the lead-attached component 1 approaches the inclined surface 23 of the mortar-shaped guide portion 21 and is released from the detachable member 40 (see FIG. 1B) at a predetermined position. .. When the leaded component 1 is released, 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 guided by the inclined surface 23. It approaches the center of the mortar-shaped guide portion 21 and stops. Here, FIGS. 2 (a) and 2 (b) show a state in which the inner lead rotation shaft 9a and the outer lead rotation shaft 9b of the lead-attached component 1 are guided and held so as to coincide with the central axis of the mortar-shaped guide portion. Shown.

Further, a chamfered portion 32 is provided at the tip of the two outer lead rotation control claws 31, and the distance t3 between the two chamfered portions 32 is larger than the diameter t1 of the through hole 22, for example, the inclination angle of the outer lead 4b. Even when θ1 is large, the tip of the outer lead 4b can be guided toward the center by the chamfered portion 32. Further, the confrontation distance t2 between the tip portions 33 of the two outer reed rotation control claws 31 can be adjusted according to the size of the inclination angle θ1 of the outer reed (see FIG. 2A). Although the through hole 22 provided at the bottom of the mortar-shaped guide portion 21 of the holding member 20 has been described as a through hole having a diameter of t1, it may be an elongated through hole.

[Explanation of Operation of Alignment Device 100: FIG. 1]
In FIG. 1A, the detachable member 40 stands by on the lead-attached component 1 separated and held by the separation and holding device 47, moves in the direction of arrow C (downward) at a predetermined timing, and attracts. The outer circumference of the stem 2 of the leaded component 1 fits into the inner circumference of the portion 41, or stops at a predetermined position immediately before fitting. Next, a predetermined negative air pressure is applied to the suction hole 42 to attract the lead-attached component 1. Next, the detachable member 40 moves in the direction of arrow C'(upward direction), then moves in the direction of arrow D (horizontal direction), and is predetermined on the alignment control unit 50 shown in FIG. 1 (b). Move to the position of. Next, the component 1 with a lead is moved in the direction of arrow E (downward), released at a predetermined position of the alignment control unit 50 with the release of the negative air pressure, and gently landed. Here, the detachable member 40 stands by at a predetermined position (in the E'direction) on the alignment control unit 50.

Next, the alignment control unit 50 improves the alignment of the lead-attached component 1 (details will be described later in FIG. 3). Then, the detachable member 40 moves in the E direction (downward direction) again, and the lead-attached component 1 having improved alignment is again attracted to the suction portion 41 of the detachable member 40. Next, the detachable member 40 moves in the direction of arrow E'(upward direction), and then in FIG. 1C, moves in the direction of arrow F (horizontal direction). Here, the detachable member 40 is positioned at a position where the outer lead 4b of the lead-attached component 1 fits into the insertion hole 11b formed in the holder 11. Then, the detachable member 40 moves in the direction of the arrow G (downward), the lead-attached component 1 moves downward, and the outer leads 4b are inserted into the insertion holes 11b and fitted into the insertion holes 11b. Further, the stem 2 is stopped when the lower surface of the stem 2 and the upper surface of the holder 11 are at a predetermined distance (temporary insertion position). As a result, the lead-attached part 1 is temporarily inserted into the holder 11 (here, the stem 2 is not press-fitted into the counterbore portion 11a). Then, when the negative air pressure is released, the leaded component 1 is released and returns to the direction of arrow G'(upward), then returns to the initial standby position shown in FIG. 1 (a), and the next leaded component 1 Wait for adsorption. Here, for example, a metal leaf spring member (not shown) is arranged inside each insertion hole 11b of the holder 11, and a predetermined pressure is applied to the side surface of the outer lead 4b due to frictional resistance. It would be nice to be able to apply the brakes.

[Explanation of alignment operation: Fig. 3]
FIG. 3 shows the positioning operation of the lead-attached component 1 in the rotation direction in the alignment control unit 50, and enlarges and displays the partial cross section of QQ ′ of FIG. 2 (b). FIG. 3A shows a state before the outer lead rotation control claw 31 is operated by inserting the lead-attached component 1 into the alignment control unit 50. FIG. 3B shows a state when the outer lead rotation control claw 31 operates and comes into contact with the outer lead 4b. FIG. 3C shows a state in which the outer lead rotation control claw 31 continues to operate and the outer lead 4b is rotated to perform positioning.

First, in FIGS. 3A or 3B, 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 leaded component 1 is guided and held by the inclined surface 23. It shows the state of being mortar. Further, the outer lead rotation shaft 9b of the lead-attached component 1 is stopped so as to coincide with the central axis of the mortar-shaped guide portion 21.

In FIG. 3A, the two outer leads 4b of the lead-attached component 1 are, for example, rotated by θ1 about the outer lead rotation shaft 9b 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 (stem 2), and the small circle (dashed line) indicates a through hole 22 formed in the holding member 20. The pair of outer lead rotation control claws 31 are in a standby position before operating toward the outer lead rotation shaft 9b (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. A part of the chamfered portion 32 of the outer lead 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 (or 32a), so that the outer lead 4b abuts on the flat portion of the outer lead rotation control claw 31. Insertion failure does not occur.

Next, in FIG. 3B, the pair of outer lead rotation control claws 31 operates toward the outer lead rotation shaft 9b (in the H direction), and the respective tip portions 33 come into contact with the outer lead 4b. is there. 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 pair of outer lead rotation control claws 31 further operates toward the outer lead rotation shaft 9b (in the H direction) to rotate the outer lead 4b in the f direction about the outer lead rotation shaft 9b. 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. 3C, the pair of outer lead rotation control claws 31 rotate the outer lead 4b in the f direction, and the inclination angle thereof is changed 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 distance (t2β) between the stop positions of the two outer lead rotation control claws 31 so that 0 <θ2, the outer lead 4b is rotated without being scratched or deformed due to pinching. Directional positioning can be performed. Next, the pair of outer lead rotation control claws 31 may return to their respective confrontation positions (H'direction) and stop at the confrontation distance t2 (see FIG. 3A) after the positioning operation is completed. However, it is desirable that the two rotation control claws 31 stop 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. .. In the rotational positioning operation of the lead-attached component 1 described with reference to FIGS. 3A to 3C, the lead-attached component 1 holds the inclined surface 23 of the mortar-shaped guide portion 21 as the positioning portion. The outer lead rotation shaft 9b of the lead-attached component 1 can be held at the center position of the mortar-shaped guide portion 21.

[Explanation of Holder 11A into which Part 1 with Lead is Temporarily Inserted: FIG. 4]
By repeating the operation described with reference to FIGS. 1 to 3 a predetermined number of times, the holder 11 can be a holder 11A in which a predetermined number of lead-attached parts 1 are temporarily inserted, as shown in FIG. Here, in the holder 11A, since the part 1 with a lead is temporarily inserted and a part of the outer lead 4b is exposed from the holder, each part 1 with a lead is flexible in the height direction, the horizontal direction, and the rotation direction. Has sex. Therefore, it is effective for improving the alignment in the post-process described later.

[Explanation of effect]
The alignment device 100 described above can improve the alignment of the outer lead 4b with respect to the lead-attached component 1 held by the separation and holding device 47 of the parts feeder, centering on the outer lead rotation shaft 9b. This makes it possible to insert the holder 11 into the insertion hole of the holder 11 without contacting the bottom surface of the counterbore portion 11a. As a result, it is possible to reduce the insertion failure of the outer lead 4b of the lead-attached component 1 into the holder insertion hole.

The shape of the holding member 20 for holding the leaded component 1 is a mortar-shaped guide portion having 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. It may be in the shape of. Further, the inclination angle θ1 of the lead of the lead-attached component 1 to be inserted into the alignment control unit 50 is preferably controlled to 60 ° or less, and more preferably 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 31 is not performed smoothly, and the risk of pinching and crushing increases. Further, the gap u between the bottom surface of the holding member 20 and the rotation control claw 31 may be set in consideration of an appropriate holding position corresponding to the length of the outer lead 4b.

Here, although not particularly limited, the main materials used for the holding member 20 of the alignment control unit 50 and the outer lead rotation control claw 31 are 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 outer lead rotation control claw 31 is coated with diamond-like carbon, for example, to form the stem of the leaded component 1. The frictional resistance with 2 and the lead 4 can be reduced.

Next, the inner reed alignment device 200 of the present invention will be described with reference to FIG. In the following description, for the sake of simplicity, the inner lead alignment device 200 will be described as "alignment device 200". FIG. 5 is a perspective view showing the configuration of the alignment device 200. 6 to 12 are cross-sectional views illustrating the alignment operation (steps 1 to 6) of the alignment device 200. Note that FIG. 12 is a partial plan view (arrow view R) for supplementary explanation of step 5. Further, FIG. 13 is a perspective view and a cross-sectional view showing an application example in which the alignment device 200 is used for manufacturing a crystal oscillator.

The point is that the part 1 with a lead is finally fixed to the holder 11.

FIG. 5 schematically shows a state in which the alignment device 200 is mounted on a part of a device for manufacturing a part with a lead (not shown). For example, in the pre-process of the alignment device 200, a predetermined number of lead-attached parts 1 are temporarily inserted into the holder 11 which is a carrier jig to form the holder 11A. In FIG. 5, the holder 11A is sent from the previous process by a traveling means (not shown) and stopped at a predetermined position of the alignment device 200.

Here, the holder 11A is stopped at the reference position in the horizontal direction and the height direction in the alignment device 200. The holder 11A is provided with, for example, two reference holes 11g (indicated by a broken line) on the lower surface 11f side of the holder 11. For example, one reference hole 11g has a cylindrical shape (see the broken line portion), and the other reference hole 11g has a cylindrical shape (not shown) having an elongated cross section. This is because a plurality of holders 11 are used as carrier jigs to cope with an error between reference holes.

Next, the elevating means 60 is arranged at a predetermined position in the height direction with respect to the holder 11A. The elevating means 60 is composed of a holder holding member 61 and a moving means (not shown) for raising and lowering the holder holding member 61 in the downward direction. Further, the elevating means 60 has a moving means (not shown) for elevating and lowering the height adjusting member 62 and the height adjusting member 62 to a predetermined position in the upward direction of the holder 11A. The holder holding member 61 and the height adjusting member 62 are made of, for example, SUS materials, and their rigidity and wear resistance are taken into consideration. The downward holder holding member 61 has a reference surface 61a, stands by at a predetermined reference position, moves in the height direction (V, V') at a predetermined time, and positions the holder 11A at a predetermined height. be able to. Further, the height adjusting member 62 in the upward direction has a reference surface 62a, stands by at a predetermined reference position, moves in the height direction (V, V') at a predetermined time, and determines the height adjusting member 62. Can be positioned at the height of.

Next, the stem holding means 70 is arranged at a predetermined position in the upward direction of the holder 11A. The stem holding means 70 is composed of, for example, a pair of holding claws 71 using a SUS material and a moving means (not shown) for moving the holding claws 71 in the horizontal direction. The pair of holding claws 71 are arranged so as to face each other from both sides with respect to the part 1 with a lead temporarily inserted into the holder 11, stand by at a predetermined position, and stand in a predetermined position in the horizontal direction (H, H'. ) Can be moved to position it in a predetermined position. Here, a predetermined number of semi-cylindrical holding surfaces 71a for holding the outer circumference of the stem 2 are provided on the tip side of the two holding claws 71, and when the two holding claws 71 sandwich the stem 2, the stem 2 is held. It is held rotatably, and the position is adjusted so that the center of the counterbore portion 11a of the holder 11 and the inner lead rotation shaft 9a of the lead-attached component 1 coincide with each other. The upper surface 71b of the pair of holding claws 71 serves as a reference surface in the height direction of the stem holding means 70, and the distance from the holder 11 is set to a predetermined height.

Next, an inner reed rotation control means 80 using, for example, a SUS material is arranged at a predetermined position in the upward direction of the stem holding means 70. The inner reed rotation control means 80 includes a pair of inner reed rotation control claws 81 and a moving means (not shown) for moving the inner reed rotation control claws 81 in the horizontal direction. The pair of inner lead rotation control claws 81 are arranged so as to face each other from both sides with respect to the lead-attached component 1 temporarily inserted into the holder 11, stand by at a predetermined position, and stand in a predetermined position in the horizontal direction (H). , H') and can be positioned at a predetermined position. Further, a vertical surface 81a for sandwiching the inner reed 4a is provided on the tip end side of the two inner reed rotation control claws 81, and the inner reed 4a can be sandwiched and positioned in the rotation direction. Further, the reference surface 81b of the inner lead rotation control claw 81 can be moved by being guided by the reference surface 71b of the holding claw 71.

Next, a configuration in which the temporarily inserted component 1 with a lead is finally fixed to the holder will be described. In the alignment device 200, a pair of holding claws 71 move in the H direction to hold the stem 2 rotatably with respect to the holder 11A into which the lead-attached component 1 is temporarily inserted, and a pair of inner leads. With the rotation control claw 81 moving in the H direction and sandwiching the inner lead 4a, the holder holding member 61 rises and presses the holder 11A against the reference surface 81b of the inner lead rotation control claw 81 to lead the lead. The attached component 1 can be fitted into the counterbore portion 11a of the holder 11. As a result, the lead-attached component 1 can be finally fixed to the holder 11. (For details, refer to the main fixing operation in FIG. 10)

[Explanation of Operation of Alignment Device 200: FIGS. 6 to 12]
Next, the operation of the alignment device 200 will be described with reference to FIGS. 6 to 12. The alignment operation and the main fixing operation for the lead-attached component 1 are divided into steps 1 to 6, and each step will be described. Note that FIG. 12 is a supplementary view illustrating the alignment operation of the inner lead 4a of FIG. 9 (arrow view R).

[Step 1: Standby of holder 11A: FIG. 6]
FIG. 6 shows a state in which the holder 11A in which the lead-attached component 1 is temporarily inserted is stopped at a predetermined position and stands by in the alignment device 200. A holder holding member 61 stands by below the holder 11A. Two reference bosses 61g are provided on the reference surface 61a of the holder holding member 61 constituting the elevating means 60 (see FIG. 5). Further, the lower surface 11f of the holder 11 is provided with two positioning holes 11g, one reference hole has a cylindrical shape and the other has a cylindrical shape with an elongated cross section, and each reference hole 11g has two positioning holes. A reference boss 61 g is inserted. Here, the height of the reference surface 61a of the holder holding member 61 is the reference position 61x, and the height of the upper surface of the holder 11 is 11x. On the other hand, the reference surface 62a of the height adjusting member 62 constituting the elevating means 60 in the upward direction of the holder 11A is the reference position 62x. Further, the pair of holding claws 71 constituting the stem holding means 70 and the pair of inner reed rotation control claws 81 constituting the inner reed rotation control means 80 are each standing by at predetermined positions.

[Step 2: Positioning of holder 11A and lift-up to the first stage: FIG. 7]
FIG. 7 shows a state in which the holder 11A is positioned and lifted up (moved in the height direction) to the first stage in the alignment device 200. Here, before the holder 11A is lifted up, the height adjusting member 62 moves in the V direction, and the reference surface 62a of the height adjusting member 62 moves from 62x to 62y and stops. Next, the holder holding member 61 moves in the V direction, and the reference boss 61g is inserted into the reference hole 11g of the holder 11A. At this position (not shown), the holder 11A is positioned in the horizontal direction by inserting the reference boss 61 g. Further, the holder holding member 61 continues to move in the V direction, and the reference surface 61a moves from the reference position 61x to 61y and stops. At this time, the upper surface position of the holder 11 moves from 11x to 11y. Here, the inner lead 4a of the lead-attached component 1 temporarily inserted into the holder 11A is adjusted so as to come into contact with the reference surface 62a of the height adjusting member 62 slightly above the upper surface position 11y of the holder 11. As a result, the parts 1 with leads can be pushed into the holder 11 by a predetermined distance, so that the heights of the inner leads 4a of the parts 1 with leads can be made uniform (improvement of alignment in the height direction). The pair of holding claws 71 and the pair of inner reed rotation control claws 81 are continuously standing by at predetermined positions.

[Step 3: Stem holding: FIG. 8]
FIG. 8 shows a state in which the stem 2 of the leaded component 1 whose height is aligned is horizontally held by a pair of holding claws 71 in the alignment device 200. Here, the pair of holding claws 71 stand by at predetermined positions so as to face the reed-attached component 1 temporarily inserted into the holder 11 from both sides, and move in the horizontal direction (H direction) from the waiting positions. Stop in place. The semi-cylindrical portion 71a of each holding claw 71 holds the stem 2 in a tubular shape and rotatably holds the part 1 with a lead (outer circumference of the stem 2). Here, the alignment in the horizontal direction is improved around the inner reed rotation shaft 9a. In particular, since the outer lead 4b is exposed and the stem portion is flexible, it is easy to improve the alignment. At this time, the upper surface of the stem 2 is adjusted so as to be slightly lower than the reference surface 71b of the holding claw 71. The reason is that the movement of the inner reed rotation control claw 81, which will be described later, is not hindered. The position of the upper surface of the stem 2 can be easily adjusted by adjusting the stop position 62y of the reference surface 62a of the height adjusting member 62 described above. The pair of inner reed rotation control claws 81 are each standing by at a predetermined position. Further, the holder holding member 61 and the holder 11 maintain the same height as in FIG. 7.

[Step 4: Improving Inner Reed Alignment: Fig. 9]
FIG. 9 shows a state in which the inner reed 4a is improved in the alignment in the rotation direction about the inner reed rotation shaft 9a by the pair of inner reed rotation control claws 81 in the alignment device 200. Here, first, the height adjusting member 62 moves in the V'direction, and the reference surface 62a retracts to the standby position 62x. Next, the pair of inner lead rotation control claws 81 move from the standby position in the horizontal direction (H direction) and stop at a predetermined position. As a result, the alignment of the inner reed 4a in the rotation direction with the inner reed rotation shaft 9a as the center is improved. Further, the holder holding member 61 and the holder 11 maintain the same height as in FIG. 7. Since the upper surface of the stem 2 is located slightly lower than the upper surface 71b of the holding claw 71, the movement of the inner lead rotation control claw 81 is not hindered. Further, details of positioning of the inner lead 4a in the rotation direction will be described later (see FIG. 12).

[Step 5: Lifting up and fixing the holder 11A to the second stage: Fig. 10]
FIG. 10 shows a state (mainly fixed) in which the stem 2 of the lead-attached component 1 having the inner lead 4a improved in alignment is fitted to the counterbore portion 11a of the holder 11 in the alignment device 200. Here, the holder holding member 61 moves in the V direction and lifts up from the first stage to the second stage. The reference surface 61a of the holder holding member 61 moves from 61y to 61z. As a result, the upper surface of the holder 11 moves from 11y to 11z. At this time, the stem 2 of the part 1 with a lead receives a force moving upward from the holder 11 and moves upward while sliding the holding surface 71a of the holding claw 71, and the upper surface of the stem 2 is an inner lead. It comes into contact with the reference surface 81b of the rotation control claw 81. Further, the holder 11 continues to receive a force of moving upward from the reference surface 61a of the holder holding member 61. As a result, the lower surface of the stem 2 of the lead-attached component 1 is fitted into the counterbore portion 11a of the holder 11, and the holder 11 stops. As a result, the lead-attached component 1 is finally fixed to the holder 11. It is desirable to adjust the pressure of the holder 11 when moving from the first stage to the second stage to an appropriate value.

[Step 6: Completion of holder 11B: FIG. 11]
FIG. 11 shows a state in which the holder 11B with a lead is completed and stands by in the standby position in the alignment device 200. Here, the holder 11B in which a predetermined number of leaded parts 1 are all fixed to the holder 11 moves in the V'direction, and the upper surface returns to the standby position 11x and stops. Further, the reference surface 61a of the holder holding member 61 moves in the V'direction, returns to the standby position 61x, and stops. The holding claw 71 and the inner reed rotating hand rotation control claw 81 each move in the H'direction, return to the standby position, and stop. Further, the reference surface 62a of the height adjusting member 62 stands by at the standby position 62x. As a result, the holder 11B is in a state where it can be moved to the next step (for example, the element joining step).

[Detailed description of inner reed alignment operation: FIG. 12]
Next, the alignment operation of the inner reed 4a will be described with reference to FIG. 12A and 12B show the arrow R of FIG. 9 as a partial plan view, FIG. 12A shows before the alignment improvement, and FIG. 12B shows after the alignment improvement. Since the basic operations of FIGS. 12 (a) and 12 (b) are the same as those of the alignment device 100 described with reference to FIGS. 3 (b) and 3 (c), the same elements are designated by the same reference numerals and are duplicated. Is omitted.

In FIG. 12A, the alignment of the inner reed 4a is deviated by θ3 about the inner reed rotation axis 9a. A state in which the tip portions 81a of the pair of inner reed rotation control claws 81 move in the H direction and come into contact with the inner reed 4a is shown. At this time, the deviation angle of the inner lead 4a is θ3. The broken line indicates the part 1 with a lead. Next, in FIG. 12B, the tip portion 81a further moves in the H direction to rotate the inner lead 4a in the f direction, and the deviation angle becomes θ4. At this time, the REIT-attached component 1 rotates in the f direction while its outer peripheral portion slides on the holding surface 71a as the inner lead 4a rotates. This improves the alignment of the inner reed 4a. Here, a predetermined minute amount is provided between the tip portion 81a of the inner reed rotation control claw 81 and the inner reed 4a so that the inner reed 4a is not scratched when sandwiched by the pair of inner reed rotation control claws 81. It is desirable to set the angle θ4 so that a clear gap δ can be secured. It should be noted that a resin material such as POM, Nylon, or hard rubber may be attached to the tip portion 81a in combination with a SUS-based material so as not to cause scratches.

[Explanation of effect]
The alignment device 200 described above can improve the alignment of the lead-attached component 1 temporarily inserted into the holder 11 with the inner lead rotation axis as the center. First, the elevating means 60 is used to improve the alignment of the inner reed 4a in the height direction, then the stem holding means 70 is used to improve the horizontal alignment of the inner reed 4a, and then the inner reed rotation control means 80 is used. It can be used to improve the alignment of the inner reed 4a in the rotational direction, and the elevating means 60 and the inner reed rotation control means 80 can be used to permanently secure the leaded component 1 to the holder 11. As a result, the accuracy of the joining position between the inner lead 4a and the element can be improved. As a result, it is possible to provide an alignment device capable of stabilizing the characteristics of the lead-attached component. Although the operation of the alignment device 200 has been described by dividing it into steps 1 to 6, the operation is not limited to this, and the operation may be divided and the procedure may be changed according to the purpose.

Further, by arranging the alignment device 100 in front of the alignment device 200 and performing a continuous process, the alignment of the outer lead 4b of the lead-attached component 1 is improved, and the lead-attached component is inserted into the holder insertion hole. By reducing defects, it is possible to improve the manufacturing efficiency of leaded parts.

Here, although not particularly limited, it is mainly used for the holder holding member 61 and the height adjusting member 62 of the elevating means 60, the holding claw 71 of the stem holding means 70, and the inner reed rotation control claw 81 of the inner reed rotation control means 80. I'll give you the ingredients. 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. In addition, for example, diamond-like carbon is formed in a region where the holder holding member 61, the height adjusting member 62, the holding claw 71, and the surface of the sliding portion and the contact portion of the inner lead rotation control member 81 come into contact with the leaded component 1. By coating the above, the frictional resistance with the stem 2 and the lead 4 can be reduced and each operation can be smoothed.

[Explanation of Application Examples Used for Manufacture of Crystal Oscillator of Alignment Device of the Present Invention: FIG. 13]
Next, an application example in which the alignment device 100 and the alignment device 200 are used in the manufacture of a crystal oscillator will be described with reference to FIG. FIG. 13A is a perspective view showing a holder 11B manufactured by using the alignment device 100 and the alignment device 200, and explaining a step of joining the crystal piece 5 to the inner reed 4a. Further, FIG. 13B is a cross-sectional view taken along the line SS'of FIG. 13A, showing the state of joining in an enlarged manner. In this application example, the "part with lead" will be described as an "airtight terminal" in the following description.

In the perspective view of the holder 11B shown in FIG. 13A, each airtight terminal 1 is fitted into the counterbore portion 11a of the holder 11 with a predetermined alignment accuracy after the alignment of the inner reed 4a is improved in the alignment device 200. It is combined and fixed. Then, the crystal piece 5 previously positioned with respect to the holder 11 is positioned with respect to the inner reed 4a of the airtight terminal 1. Further, in FIG. 13B, the accuracy of the joining position of the crystal piece 5 with respect to the inner reed 4a is improved by controlling the gap δ.

Next, the paste-like solder (not shown) applied to the inner reed 4a is heated and melted to perform bonding. As a result, the crystal piece 5 is electrically and mechanically connected to the airtight terminal 1. Next, the holder 11B moves to a frequency adjusting step (not shown) and adjusts the oscillation frequency of the crystal piece 5 by a predetermined method. Next, the holder 11B moves to a sealing step of a sealing tube (not shown), and the sealing tube is press-fitted and sealed in a predetermined atmosphere such as a vacuum. Next, the holder 11B moves to an electrical characteristic inspection step (not shown) to perform an electrical characteristic inspection as a crystal oscillator. Finally, the holder 11B moves to a step of removing the crystal oscillator (not shown), and the crystal oscillator is removed from the holder 11B to complete the crystal oscillator.

As described above, by applying the alignment device 100 and the alignment device 200 in the crystal oscillator manufacturing apparatus, the alignment of the inner lead of the airtight terminal 1 is improved and the accuracy of the bonding position between the inner lead and the crystal piece is improved. Therefore, it is possible to provide stabilization of the characteristics of the crystal unit. Further, by improving the alignment of the outer reed and reducing the improper insertion of the airtight terminal 1 into the holder, the manufacturing efficiency of the crystal oscillator can be improved.

Although the explanation has been given that the alignment device 100 and the alignment device 200 are applied to the manufacturing process of the crystal oscillator, the present invention is not limited to this, and can be applied to, for example, leaded parts such as semiconductor elements, resistors, and capacitors.

The present invention can be applied to lead-attached parts such as semiconductor elements, crystal oscillators, resistors, and capacitors widely used in OA, home appliances, automobiles, etc., as well as in the electronics field, and is particularly applied to wristwatches, portable electronic devices, and the like. Regarding the alignment device in the manufacture of small leaded parts to be used, the characteristics of leaded parts are improved by inserting the leads of the leaded parts into the insertion holes of the holder as a carrier jig to improve the joining accuracy between the inner leads and the element. It is suitable for an alignment device that can perform stabilization. It is also suitable as a device that can reduce defective insertion of leaded parts into the holder.
