[0013]

[First Embodiment] FIGS. 1 to 6 show a first embodiment of a component supply apparatus to which the present invention is applied.
In the drawings, an apparatus suitable for handling a quadrangular prism-shaped electronic component P having a dimensional relationship of length> width = height is illustrated for convenience of explanation. In the following description, the left in FIG. 1 is described as front, the right as rear, the near side as left, and the far side as right.

The apparatus according to the first embodiment includes a main body 1
, A lid plate 2, a suction plate 3, and a motor 4 for driving the suction plate.

The main body 1 has a chamber 1a for accommodating a large number of electronic components P in a direction-unregulated state. Incidentally, the “direction unregulated state” means a state in which the electronic component P can freely move three-dimensionally. The chamber 1a has an upper end opened, and the upper end opening is openably and closably covered by a lid plate 2. In the drawing, the chamber 1a is shown as having a non-sloping bottom surface, but this bottom surface may be inclined downward to the right if necessary.

Further, on the upper right side of the chamber 1a,
A recess having a depth substantially the same as the width or height of the electronic component P is formed, and a width between the lower edge of the recess and the right side surface of the chamber has the same width as the depth of the recess. Further, a step is formed, which is inclined downward from the rear to the front. In the illustrated device, this step is caused by the electronic component P
Is a part moving path 1b which enters in a predetermined direction and moves by its own weight. Of course, the width dimension (the depth dimension of the concave portion) of the component moving path 1b may be slightly smaller or slightly larger than the width dimension or the height dimension of the electronic component P.

Further, an inlet of the supply passage 1c is formed on the front surface of the chamber 1a, and a lower side of the inlet of the supply passage 1c is continuous with a front end (end) of the component moving path 1b. The horizontal interval and the vertical interval of the supply passage 1c are slightly larger than the width dimension or the height dimension of the electronic component P. In other words, the supply passage 1c has a slightly larger cross-sectional shape similar to the shape of the end face of the electronic component P, and can take in the electronic component P in a two-way regulated state and pass it in the same state. Incidentally, the “two-way restricted state” means a state in which the electronic component P is restricted from moving in two directions, and the electronic component P can move one-dimensionally (linearly).

Further, a movement restricting portion 1d is formed above the inlet of the supply passage 1c so as to protrude toward the chamber 1a. The movement restricting portion 1d has a lower surface continuous with the upper surface of the supply passage 1c, and
b, and has a tapered surface that rises rearward on the rear side of the lower surface. The role of the movement restricting section 1d will be described later in the description of the operation.

Further, a circular recess 1e for disposing the motor 4 is formed in the lower front side of the left side surface of the main body 1, and a shaft 4a of the motor 4 is inserted into the bottom of the circular recess 1e. A circular hole 1f is formed.

The suction plate 3 is formed to have a predetermined thickness and length, and one end of the suction plate 3 is connected to a shaft 4 a of the motor 4. A plurality of disk-shaped or rectangular permanent magnets 3a (seven in the figure) are embedded at equal intervals on the surface of the suction plate 3 on the main body 1 side.
As the permanent magnet 3a, a samarium-cobalt magnet, a ferrite magnet, or the like is used. Each permanent magnet 3a is buried so that one of the N-pole and S-pole curved surfaces is exposed. When the attracting plate 3 is connected to the shaft 4a of the motor 4, the exposed surface of the permanent magnet 3a or the attracting plate The magnet embedding surface 3 is in contact with the outer surface of the right side wall of the main body 1 or faces through a slight gap. Since the main body 1 is made of a magnetically permeable material such as resin, the magnetic force of each permanent magnet 3a extends to the electronic components P in the chamber 1a via the right side surface of the chamber 1a.

When supplying parts, as shown in FIG.
The lid plate 2 is opened to store a large number of electronic components P in the chamber 1a. The electronic components P are, for example, chip components such as a chip capacitor, a chip resistor, and a chip inductor, composite components such as an LC filter, array components such as a capacitor array and an inductor array, and other types of electronic components. Then, the suction plate 3 at the lowered position (see FIG. 1) is rotated counterclockwise by a predetermined angle (about 70 degrees in the drawings) as shown in FIGS. 4 and 5 by the motor 4, and then returned to the lowered position. Repeat the action to make it work.

The electronic component P in the chamber 1a is moved by the magnetic force of each permanent magnet 3a of the suction plate 3 to the chamber 1a.
When the suction plate 3 is rotated in a counterclockwise direction as shown in FIGS. 4 and 5 in order to be attracted to the right side surface of the chamber 1a and to be brought into close contact with one side surface of the chamber 1a as shown in FIGS. The electronic component P adhered to the surface moves upward along the right side surface of the chamber 1a along with the operation of the suction plate 3, and enters the component moving path 1b in a predetermined direction during the upward movement. Of course, there is an electronic component P that enters the component moving path 1b while the suction plate 3 returns from the raised position to the lowered position.

The electronic component P that has entered the component moving path 1b
As shown in FIG. 6A, basically, the electronic component P has a posture in which one side surface is in contact with the upper surface of the step, and another adjacent side surface is in contact with the inner surface of the concave portion. In FIG. 6 (B)
As shown in FIG. 5, there is an electronic component P that enters the component moving path 1b in such a manner that a part of one side surface is in contact with the upper surface of the step and one adjacent longitudinal end surface is in contact with the inner surface of the concave portion. Since the posture is unstable, such an electronic component P falls naturally or falls down from the component moving path 1b due to vibration or the like accompanying the operation of the suction plate 3.

The part moving path 1 in the proper posture shown in FIG.
The electronic component P that has entered the component moving path 1b slides on the component moving path 1b according to its inclination when the attraction plate 3 is separated from the component moving path 1b and the magnetic force from each permanent magnet 3a does not reach the electronic component P. Thus, it moves under its own weight toward the inlet of the supply passage 1c. At this time, even if there is an electronic component P entering the component moving path 1b in the posture shown in FIG. 6C, the electronic component P is removed from the component moving path 1b when it comes into contact with the movement restricting portion 1d. Or fall into the supply passage 1c with the correct posture.
The electronic component P, which moves by its own weight along the component movement path 1b in the proper posture shown in FIG. 6A, enters the supply passage 1c in the same posture without contacting the movement restricting portion 1d.

When the electronic component P that has entered the supply passage 1c is transported forward, a negative pressure is applied to the front end of the supply passage 1c by using, for example, a mechanically operated cylinder or an electric vacuum pump with a suction source. Act. The electronic component P that has entered the supply passage 1c is drawn forward by this negative pressure action and is transported to the target position. The electronic components P transported to the target position are sequentially taken out by a suction nozzle or the like at the timing when the negative pressure is temporarily released, and are mounted on a substrate or the like.

As described above, according to the device of the first embodiment,
Due to the rotational movement of the suction plate 3 having the permanent magnet 3a, the electronic component P stored in the chamber 1a in an unregulated direction is moved upward along the right side surface of the chamber 1a by using the magnetic force of the permanent magnet 3a. Part moving path 1b
The electronic component P that moves along the component moving path 1b can be fed into the supply path 1c in a two-way regulated state.

The apparatus according to the first embodiment is excellent in the ability to arrange the electronic components P housed in the chamber 1a in a direction-unregulated state in the same direction as each other, and supplies the quadrangular prism-shaped electronic components P. Even when targeted, a high alignment ability can be exhibited. In addition, since the configuration related to component alignment is simple, it can contribute to cost reduction and has high versatility as an alignment supply unit.

Further, the operation of aligning and supplying the electronic components P housed in the chamber 1a in the direction unregulated state can be performed continuously and efficiently. It is possible to obtain a supply performance that can follow component removal in a cycle.

In the above-described apparatus, the component moving path 1b
Electronic component P that has entered the position shown by the broken line in FIG.
In order to remove the electronic component P from the component moving path 1b, a chamfer 1b1 or a rounded edge may be provided at the edge of the component moving path 1b as shown in FIG. Further, in order to guide the moving direction of the electronic component P in the component moving path 1b, a rising portion 1b2 as shown in FIG. 7B may be provided at an edge of the component moving path 1b.

In the above-described apparatus, a step is formed on the right side surface of the chamber 1a and this step is used as the component moving path 1b. However, as shown in FIGS. On the right side surface, a groove having a U-shaped cross section inclined downward from the rear to the front, specifically, a vertical space and a horizontal space (depth) are slightly larger than the width dimension or the height dimension of the electronic component P. A groove may be formed and this groove may be used as the component moving path 1g. In the case of such a component moving path 1g, it is possible to accurately prevent the electronic component P from entering the component moving path 1g in a posture indicated by a broken line in FIG.

In the case of such a component moving path 1g as well, it is inevitable that the electronic component P enters in the posture shown by the broken line in FIG.
As shown in FIG. 8C, a chamfer 1g1 or roundness may be provided on the bottom edge of the component moving path 1g, or a chamfer 1g2 or roundness may be provided on the upper edge of the component moving path 1g as shown in FIG. If this is the case, it is possible to easily drop the electronic component P that has entered in an inappropriate posture. Further, as shown in FIG. 9 (A), if an overhang portion 1h having an inclined surface is provided inside the upper surface of the component moving path 1g, the component moving path 1g is placed in the posture shown by the broken line in FIG. 9 (B). It is possible to reliably prevent the electronic component P from entering, and to allow the electronic component P to enter the component moving path 1g only in an appropriate posture.

Further, in the above-described apparatus, the suction plate 3
Is continuously rotated back and forth, but the supply passage 1c
A component presence / absence detection sensor is provided at a predetermined position of the
c, the rotation of the suction plate 3 is completely stopped in a state where the electronic components P are almost completely lined up in c, and the rotation of the suction plate 3 is restarted when the number of the electronic components P in the supply passage 1c decreases. Such an operation method may be adopted.

Further, in the above-described apparatus, the electronic components P after being aligned and supplied are transported sideways. However, when a transport member such as a tube capable of transporting the electronic components P by its own weight is used, supply The passage 1c is configured to be vertically oriented through an inclined portion or a curved portion, and the electronic component P taken in the supply passage 1c is moved downward by its own weight to be sent to a transport member such as a tube. No problem.

Further, in the above-mentioned apparatus, the one having a single supply system is shown. However, as shown in FIGS. 10 and 11 (A), the apparatus comprises a U-shaped groove having a transverse cross-section and has a longitudinal length. (Three in the figure) inclined component moving paths 1g
Are formed on the right side surface of the chamber 1a at intervals in the vertical direction, and a plurality of (three in the figure) inclined supply passages 1c continuous with the front end (end) of each component moving path 1g are formed.
Electronic components P can be sent to a plurality of supply systems. In addition, a part moving path 1g consisting of a U-shaped cross section groove
Can be configured by a component moving path 1b composed of a step as shown in FIG. 11 (B). In this case, the lower wall thickness of the right side wall of the chamber 1a increases due to the number of steps, but even if the lower wall thickness of the right side wall of the chamber 1a increases, the magnetic force of the permanent magnets 3a of the suction plate 3 is reduced. There is no particular problem when the electronic component P in the chamber 1a is extended via the right side surface of 1a. The permanent magnet 3a of the attraction plate 3 is determined due to the lower wall thickness.
If it becomes difficult or impossible for the magnetic force to reach the electronic component P in the chamber 1a, a downward-sloping inclined surface is formed on the outside of the right wall to reduce the thickness of the lower part of the right wall of the chamber 1a. It is preferable that the suction plate 3 is formed and the suction plate 3 is operated along the inclined surface.

Further, in the above-described apparatus, the suction plate 3
In FIG. 12, the suction plate 5 having the permanent magnet 5a is translated from the bottom to the top, and the top plate is moved from the top to the bottom, as shown in FIG. The same operation and effect as described above can be obtained by repeating the movement operation.

By the way, as shown in FIG.
In order to move the parts vertically, as shown in FIG. 13, a plurality of (three in the figure) vertical component moving paths 1g ′ each having a U-shaped cross section are formed on the right side of the chamber 1a. If a plurality of (three in the figure) vertical supply passages 1c 'are formed at intervals in the direction and are continuous with the lower end (end) of each component movement path 1g', a plurality of supply systems can be connected. Electronic components P can be sent. A permanent magnet 5a is provided between the suction plate 5 at the lowered position and the supply passage 1c '.
If the magnetic force blocking portion 6 made of a magnetic material such as iron is provided to block the suction action from reaching the electronic component P in each supply passage 1c ', the components can be moved even when the suction plate 5 is at the lowered position. A magnetic force can be prevented from being applied to the electronic components P sent from the path 1g 'to the respective supply passages 1c', and the components can be smoothly sent to the respective supply passages 1c '.

In this case, two suction holes for holding the electronic components P are formed vertically on the inner surface of each supply passage 1c ', and a negative pressure is applied to the lower suction hole to supply each supply passage 1c'. By holding the lowest electronic component P in 1c 'by suction, the downward movement of the electronic component P in each supply passage 1c' is regulated, while applying a negative pressure to the upper suction hole and lowering the lower suction. By releasing the negative pressure effect of the holes, it is also possible to selectively move the electronic components P in each supply passage 1c 'downward one by one.

Further, if the component moving path 1g "as shown in FIG. 14 is formed by enlarging the depth dimension of the component moving path 1g ', the electronic components P in the chamber 1a can be transferred to each of the component moving paths 1g'.
g ”in the two-way regulated state and can be moved by its own weight. A surface 1a1 that is inclined downward toward each supply passage 1c ′ is formed at the bottom of the chamber 1a and at the lower end of each component moving path 1g ″. If you do, each part moving path 1
g ”in electronic components P taken in two-way regulated state
While the supply passages 1 are guided by the inclined surface 1a1.
It can be fed into c ′ in a one-way regulated state. If the magnetic force of the permanent magnet 5a of the attraction plate 5 becomes difficult to reach or does not reach the electronic components P in the chamber 1a due to the relationship of the depth of each component moving path 1g ", each component moving path 1g". It is preferable to form vertical grooves on the outer surface side of the thick portion existing between them, and make the shape of the attraction plate 5 comb-like so that the permanent magnets 5a enter the respective vertical grooves.

[Second Embodiment] FIGS. 15 to 22 show a second embodiment of a component supply apparatus to which the present invention is applied. In the drawings, an apparatus suitable for handling a quadrangular prism-shaped electronic component P having a dimensional relationship of length> width = height is illustrated for convenience of explanation. In the following description, the left in FIG. 15 is described as front, the right as rear, the near side as left, and the far side as right.

The apparatus according to the second embodiment has a main body 11
, Two guide plates 12, a permanent magnet 13, and a drive mechanism (not shown) for the permanent magnet.

The main body 11 has a chamber 11a for accommodating a large number of electronic components P in a direction-unregulated state. The chamber 11a has a predetermined thickness and an upper wall that is entirely curved. In the illustrated apparatus, the inner surface (upper surface of the chamber) formed of a curved surface serves as a component sliding surface 11b on which the electronic component P can slide. ing. By the way,
The “direction-unregulated state” means a state in which the electronic component P can freely move three-dimensionally.

Further, on the front upper portion of the chamber 11a,
Flat space 11 having the same left-right spacing as chamber 11a
The upper surface of the flat space 11c is continuous with the front end (end) of the component sliding surface 11b. The vertical space of the flat space 11c is slightly larger than the width or height of the electronic component P.

Further, a supply passage 11d is formed in front of the flat space 11c so as to communicate with the flat space 11c. The vertical interval of the supply passage 11d is the flat space 11
The same as the vertical spacing of c, the horizontal spacing is slightly larger than the width or height of the electronic component P. That is, the supply passage 11d has a slightly larger cross-sectional shape similar to the shape of the end face of the electronic component P, and can take in the electronic component P in a two-way regulated state and pass it in the same state.
Incidentally, the “two-way restricted state” means a state in which the electronic component P is restricted from moving in two directions, and the electronic component P can move one-dimensionally (linearly).

Each of the two guide plates 12 has, at the rear end thereof, a guide surface 12a inclined from the outside to the inside. The left-right width of each guide plate 12 is ((left-right space of flat space 11c)-(left-right space of supply passage 11d)).
X1 / 2, the vertical thickness is equal to the vertical spacing of the flat space 11c. Each guide plate 12 has a flat space 11c.
17, a passage (a gap between plates) is formed between the two plates 12 and plays a role similar to that of the supply passage 11d. Since the front-rear length of one guide plate 12 is shorter than the front-rear length of the other guide plate 12, the position of each guide surface 12a is shifted in the front-rear direction. Further, in a state where both the guide plates 12 are arranged in the flat space 11c, a rear region where the both guide plates 12 do not exist in the flat space 11c is:
The electronic component P can be taken in a one-way regulated state. Incidentally, the “one-direction restricted state” means that the movement of the electronic component P in one direction is restricted, and the electronic component P is two-dimensional (planar).
It means that you can move.

The permanent magnet 13 is made of a samarium-cobalt magnet, a ferrite magnet, or the like, and has left and right dimensions corresponding to the component sliding surface 11b. This permanent magnet 13 is N
One of the pole and the south pole is the component sliding surface 11b of the chamber 11a.
So as to face the outside of the curved upper wall of the chamber 11a or with a slight gap therebetween. Since the main body 11 is formed of a magnetically permeable material such as resin, the magnetic force of the permanent magnet 13 reaches the electronic components P in the chamber 11a via the curved upper wall of the chamber 11a. The permanent magnet 13 can be moved on a predetermined trajectory along the outer surface of the curved upper wall of the chamber 11a by a drive mechanism (not shown). This movement will be described later in detail in the operation description.

When supplying components, as shown in FIG. 14, a large number of electronic components P are stored in the chamber 11a. The main body 1 opens and closes the window that opens to the chamber 11a.
1, the parts can be easily stored. The electronic components P are, for example, chip components such as a chip capacitor, a chip resistor, and a chip inductor, composite components such as an LC filter, array components such as a capacitor array and an inductor array, and other types of electronic components. Then, the operation of moving the permanent magnet 13 along the trajectories shown in FIGS. 18 to 20 and 22 by the driving mechanism is repeated.

The electronic component P in the chamber 11a is attracted to the component sliding surface 11b of the chamber 11a by the magnetic force of the permanent magnet 13 and is brought into close contact with the component sliding surface 11b in such a manner that one side thereof is in contact therewith. As shown in FIG. 18 and FIG. 19, when the permanent magnet 13 is moved from the lower position to the upper position, the electronic component P in close contact with the component sliding surface 11b slides on the component sliding surface 11b along with the operation of the permanent magnet 13. Move from the bottom to the top in the flat space 1
1c enters the rear area in a one-way regulation state, and
As shown in FIG. 21, the two guide plates 12 enter the gap between the plates while their postures are corrected by the guide surfaces 12a.

Thereafter, as shown in FIG.
Is moved upward from the ascending position, the magnetic force from the permanent magnet 13 does not reach the electronic component P, and the electronic component P separates from the component sliding surface 11b. By the way, the permanent magnet 13
Returning from the position shown in FIG. 20 to the position shown in FIG.
Return to the initial position shown in. Thereafter, the permanent magnet 13 reciprocates in the same orbit as described above.

When the electronic component P, which has entered the gap between the plates, is transported forward through the supply passage 11d, the supply passage 11d is supplied using a suction source such as a mechanically operated cylinder or an electric vacuum pump. Negative pressure is applied to the front end of. The electronic component P that has entered the gap between the plates is drawn forward by this negative pressure action as shown in FIG. 22, and the electronic component P in the rear area of the flat space 11c is also drawn forward similarly to be transported to the target position. Is done. The electronic components P transported to the target position are sequentially taken out by a suction nozzle or the like at the timing when the negative pressure is temporarily released, and are mounted on a substrate or the like.

As described above, according to the device of the second embodiment,
By the reciprocating motion of the permanent magnet 13, the electronic component P stored in the chamber 11 a in an unregulated direction is moved upward along the component sliding surface 11 b using the magnetic force of the permanent magnet 13, and the posture is moved by the guide plate 12. While correcting, it can be fed into the supply passage 11d in a two-way regulated state.

The apparatus according to the second embodiment includes a chamber 11a
It is excellent in the ability to arrange the electronic components P housed in the direction unregulated in the same direction, and can exhibit high alignment ability even when the quadrangular prism-shaped electronic components P are to be supplied. it can. In addition, since the configuration related to component alignment is simple, it can contribute to cost reduction and has high versatility as an alignment supply unit.

Further, since the operation of aligning and supplying the electronic components P stored in the chamber 11a in the direction unrestricted state can be performed continuously and efficiently, when the electronic components P are used as a bulk feeder, high speed operation is possible. It is possible to obtain a supply performance that can follow component removal in a cycle.

In the above-described apparatus, an example in which the two guide plates 12 are fixedly arranged is exemplified. However, at least one of the guide plates 12 may be reciprocated in the front-rear direction by using a solenoid or the like. In this way, the posture correcting action by the guide surface 12a of the guide plate 12 can be more positively performed.

In the above-described apparatus, the permanent magnet 13 is reciprocated continuously. However, a component presence / absence detection sensor is provided at a predetermined position in the supply passage 11d, and the supply passage 11d is provided.
The movement of the permanent magnet 13 is completely stopped in a state in which the electronic components P are almost fully lined up in d, and the movement of the permanent magnet 13 is restarted when the number of the electronic components P in the supply passage 11d decreases. Such an operation method may be adopted.

Further, in the above-described apparatus, the electronic components P after being aligned and supplied are transported sideways. However, when a transport member such as a tube capable of transporting the electronic components P by its own weight is used, the electronic component P is flat. The space is inclined or curved so that the supply passage 11d is oriented vertically, and the electronic component P taken in the supply passage 11d is moved downward by its own weight to be sent to a conveying member such as a tube.

[Third Embodiment] FIGS. 25 to 28 show a component supply apparatus according to a third embodiment of the present invention. In the drawings, an apparatus suitable for handling a quadrangular prism-shaped electronic component P having a dimensional relationship of length> width = height is illustrated for convenience of explanation. In the following description, the left side in FIG. 25 is described as front, the right side as rear, the near side as left, and the far side as right.

The device according to the third embodiment includes a main body 21
, A lid plate 22, a permanent magnet 23, a slider 24, and a solenoid 25 for driving the slider.

The main body 21 has a chamber 21a for accommodating a large number of electronic components P in a direction-unregulated state. Incidentally, the “direction unregulated state” means a state in which the electronic component P can freely move three-dimensionally. The upper end of the chamber 21 a is open, and the upper end of the chamber 21 a is openably and closably covered by a lid plate 22.

The right side of the chamber 21a is provided with a recess 21b for accommodating the slider 24 in a vertically movable manner. The opening shape and the depth dimension of the concave portion 21b are:
The shape and thickness dimension of the slider 24 substantially match.

Further, an opening dimension and a depth dimension slightly larger than the width dimension or the height dimension of the electronic component P are provided on the right side of the chamber 21a on the front side of the concave portion 21b.
Further, a groove which is inclined downward from the rear to the front is formed. In the illustrated device, this groove forms a component moving path 21c in which the electronic component P enters in a predetermined direction and moves by its own weight.

Further, an inlet for a supply passage 21d is formed on the front surface of the chamber 21a.
The lower side of the entrance 1d is continuous with the front end (end) of the component moving path 21c. The horizontal distance of the supply passage 21d is the component moving path 2
1c, which is slightly larger than the width or height of the electronic component P. That is, the supply passage 21d has a slightly larger cross-sectional shape similar to the end face shape of the electronic component P, and
It can be taken in the direction-restricted state and passed through in the same state. Incidentally, the “two-way restricted state” means a state in which the electronic component P is restricted from moving in two directions, and the electronic component P can move one-dimensionally (linearly).

The permanent magnet 23 is formed of a samarium-cobalt magnet, a ferrite magnet, or the like into a disc shape or a rectangular shape. In the illustrated apparatus, a plurality of (three in the figure) permanent magnets 23 are arranged such that one of the N pole and the S pole faces the chamber 21a side, and is vertically arranged along the recess 21b.
The main body 21 is fixed to the outer surface of the right side wall. Since the main body 21 and the slider 24 are formed of a magnetically permeable material such as resin, the magnetic force of each permanent magnet 23 reaches the electronic component P in the chamber 21a via the right side surface of the main body 21 and the slider 24. It has become. Further, the uppermost permanent magnet 23 is located at a position lower than the component moving path 24a of the slider 24 at the raised position,
The magnetic force does not reach the component moving path 24a of the slider 24 at the raised position.

The slider 24 has a groove on the left side having the same size and inclination as the groove constituting the component moving path 21c. In the illustrated device, this groove is formed by the component moving passage 24a in which the electronic component P enters in a predetermined direction and moves by its own weight.
It has become. The slider 24 is mounted on the main body 21.
Is vertically movably accommodated in the concave portion 21b, and a lower portion thereof protrudes outside through the hole 21e. This slider 2
4 is connected to an arm 25 a of a solenoid 25 attached to a lower portion of the main body 21.

Then, the operation of raising the slider 24 at the lowered position (see FIG. 25) by the solenoid 25 as shown in FIGS. 27 and 28 and returning to the lowered position is repeated.

The electronic components P in the chamber 21a are attracted by the magnetic force of the permanent magnet 23 to the left side surface of the slider 24 which is in the process of rising, whereby some electronic components P enter the grooves constituting the component moving path 24a. The electronic component P that has entered the groove enters the component moving path 21c in such a manner that one side thereof contacts the lower surface of the groove and the other adjacent side contacts the inner surface of the groove (see FIG. 28).

When the slider 24 reaches the raised position and the component moving path 24a coincides with the component moving path 21c on the right side of the chamber, the electronic component P entering the component moving path 24a of the slider 24 has the uppermost permanent magnet 23 And the electronic component P moves under its own weight so as to slide on the component moving path 24a according to its inclination (see FIG. 28). The electronic component P, which moves by its own weight along the component moving path 24a of the slider 24, moves to the component moving path 21c on the right side of the chamber in the same posture, and further moves by its own weight so as to slide along the component moving path 21c according to its inclination. It enters the supply passage 21d.

The main body 31 is provided with a first chamber 31a for accommodating a large number of electronic components P in a direction-unregulated state.
Inside. By the way, "direction unregulated state"
This means a state in which the electronic component P can move freely in three dimensions.
The first chamber 31a has an upper end opened, and the upper end opening is openably and closably covered by a lid plate 32. The bottom surface of the first chamber 31a is composed of two inclined bottom surfaces 31a1 and 31a2 having different height positions, and a vertical flat surface 31a3 is exposed at the lower edge of the rear inclined bottom surface 31a1.

Further, below the first chamber 31a,
A flat space 31b having the same horizontal space as the first chamber 31a is formed, and the rear surface of the flat space 31b is continuous with the flat surface 31a3. The distance between the front and rear of the flat space 31b is slightly larger than the width or height of the electronic component P.

As shown in FIG. 34, a passage (a gap between plates) is formed between the two plates 33 and plays a role similar to that of the supply passage 31c. Since the vertical length of one guide plate 33 is shorter than the vertical length of the other guide plate 33, the position of each guide surface 33a is shifted in the vertical direction. Further, in a state where both the guide plates 33 are arranged in the flat space 31b, the upper region where the both guide plates 33 do not exist in the flat space 31b is:
The second chamber (hereinafter, the same reference numeral 31b as the flat space is used in combination) that can take in the electronic component P in the one-way regulated state. Incidentally, the “one-way restricted state” means that the electronic component P is restricted from moving in one direction, and the electronic component P
It means a state that can move in a dimensional (planar) manner.

The support rod 34 serves to guide the movement and the direction of movement of the suction block 35. The upper and lower ends of the support rod 34 are fixed to the upper surface and the lower surface of the concave portion 31d of the main body 31, and the distance between the left and right of the concave portion 31d is fixed. It is located in the center.

As shown in FIG. 33A, the suction block 35 has a rectangular parallelepiped shape as a whole, and includes a magnet portion 35a made of a permanent magnet such as a samarium-cobalt magnet or a ferrite magnet at an upper portion and a lower portion. Have. At the center of the suction block 35, a through hole 35b through which the support rod 34 is inserted is formed. In a state where the suction block 35 is mounted on the support rod 34, as shown in FIG.
One of the N pole and the S pole of the two magnet portions 35a is directly opposed to the second chamber 31b. Further, an arm 35a of a solenoid 35 attached to the right side of the main body 31 is connected to the center of the right side of the suction block 35. Various forms of the suction block 35 can be adopted. For example, a suction block 35 'as shown in FIG.
What is embedded may be used so that a 'is exposed.

The two magnetic force interrupting portions 36 are formed in a plate shape from a magnetic material such as iron, and each magnet portion 35a of the suction block 35 at the lower position and the second chamber 31b are formed.
Between the main body 31
Is provided on the front side surface of the concave portion 31d. Each magnetic force blocking portion 36 is for preventing the magnetic force from each magnet portion 35a of the suction block 35 from reaching the electronic component P in the second chamber 31b. Are slightly larger than the horizontal width and the vertical width of each magnet portion 35a.

When the suction block 35 rises from the lower position and the upper magnet portion 35a comes off from the upper magnetic force blocking portion 36, the main body 31 is made of a magnetically permeable material such as resin. The magnetic force of the magnet part 35a reaches the lower part of the first chamber 31a, and the first chamber 31a
The electronic components P inside are subjected to the stirring action, and some of the electronic components P are drawn to the flat surface 31a3 and
a3 is brought into close contact with one side surface thereof. When the suction block 35 starts lowering from the raised position, the electronic component P that is in close contact with the flat surface 31a3 moves downward along with the operation of the suction block 35 and enters the second chamber 31b in a one-way regulated state. When the suction block 35 reaches the lowered position, the magnetic force of the upper magnet portion 35a is reduced to the upper magnetic force blocking portion 3
When the electronic component P enters the second chamber 31b, the electronic component P falls under its own weight toward the lower guide plate 33, and enters the gap between the plates while the posture is corrected by the guide surface 33a.

Is the lower magnet section 35
It is attracted by the magnetic force of a and moves upward. When the suction block 35 starts lowering from the raised position, the electronic component P attracted by the magnetic force of the lower magnet portion 35 a moves downward in accordance with the operation of the suction block 35. In other words, the electronic component P that is about to enter the gap between the plates from the second chamber 31b is moved up and down by the lower magnet portion 35a, and thereby the two guide plates 33 are moved.
The posture correcting action by the guide surface 33a is promoted. When the suction block 35 reaches the lowered position and the magnetic force of the lower magnet portion 35a is blocked by the lower magnetic blocking portion 36, the electronic component P that has entered the gap between the plates moves toward the lower supply passage 31c. It falls under its own weight and enters the supply passage 31c.

When the electronic component P that has entered the supply passage 31c is transported forward, a negative pressure is applied to the front end of the supply passage 31c using a suction source such as a mechanically operated cylinder or an electric vacuum pump. Let it work. Supply passage 31c
The electronic component P that has entered inside is drawn forward by this negative pressure action and is transported to the target position. The electronic components P transported to the target position are sequentially taken out by a suction nozzle or the like at the timing when the negative pressure is temporarily released, and are mounted on a substrate or the like.

As described above, according to the device of the fourth embodiment,
