Description

Electronic component separator

The present invention relates to an electronic component separating apparatus.

For example, relatively large electronic components are used for power circuit boards. Since such electronic components differ in shape and dimensions, mounting on a substrate is generally performed by manual mounting. In recent years, there has been a growing need for a technology for automatically mounting such electronic components on a substrate using a robot arm or the like.

However, the above-mentioned electronic parts tend to get tangled with each other at the time of packing or transportation, and the parts need to be sufficiently separated before being picked up by the robot arm. An electronic component having a relatively long lead or an electronic component having a complicated shape is particularly entangled.

Japanese Patent Laid-Open No. 5-139525

The inventors discovered a new technique for separating electronic components entangled with each other after intensive research.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a novel electronic component separation apparatus that separates electronic components.

An electronic component separating apparatus according to an aspect of the present invention includes a bottom plate having a circular outer edge on which an electronic component is disposed, and an annular side wall that extends upward from the outer edge of the bottom plate and surrounds the outer edge of the bottom plate. A rotary pallet having a rotating pallet around the central axis of the side wall, and a rotating piece that rotates on the bottom plate of the circular pallet and contacts an electronic component disposed on the bottom plate of the circular pallet. A rotation separation unit.

According to the present invention, a novel electronic component separating apparatus for separating electronic components is provided.

FIG. 1 is a schematic configuration diagram illustrating an electronic component separating apparatus according to an embodiment. FIG. 2 is a plan view of the turntable shown in FIG. FIG. 3 is a schematic perspective view of the pallet assembly shown in FIGS. FIG. 4 is a schematic perspective view showing a pallet of the pallet assembly of FIG. FIG. 5 is a diagram illustrating the electronic component according to the embodiment. FIG. 6 is an enlarged view of a main part of the pallet assembly shown in FIG. FIG. 7 is an enlarged view of a main part of the pallet assembly shown in FIG. FIG. 8 is an enlarged view of a main part of the pallet assembly shown in FIG.

Hereinafter, embodiments will be described with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same elements or elements having the same functions, and redundant description is omitted.

The electronic component separating apparatus 1 shown in FIG. 1 accepts an assembly of electronic components from the outside of the device and separates the assembly of electronic components into individual electronic components so that they can be easily used in subsequent processes. To separate. In the following, as an example of a post-process, a separated electronic component is picked up by a robot arm and mounted on a predetermined substrate.

As shown in FIGS. 1 and 2, the electronic component separating apparatus 1 includes a support base 10, a rotary table 20 that is rotatably mounted on the support base 10, and a plurality of pallets that are arranged on the rotary table 20. And an assembly 30.

The support base 10 stably supports the rotary table 20 from below, and a motor (not shown), various cables, and the like that rotate the rotary table 20 are disposed therein.

The rotary table 20 is a disk-like table extending in the horizontal direction, and is rotationally driven by a motor in a horizontal plane. The turntable 20 is controlled to rotate at a predetermined angle (for example, 45 degrees) around the rotation axis _R0 extending in the vertical direction at a predetermined timing, for example. Further, the rotary table 20 is rotatable in both directions (clockwise and counterclockwise) as indicated by arrows in FIG.

The number of the plurality of pallet assemblies 30 is eight in the embodiment shown in FIGS. 1 and 2 and is also referred to as pallet assemblies 30A to 30H in the following description.

As shown in FIG. 2, the eight pallet assemblies 30 arranged on the turntable 20 are regularly arranged at an angular interval of 45 degrees with respect to the rotation axis R ₀ of the turntable 20. Therefore, when the turntable 20 rotates 45 degrees, the adjacent pallet assembly 30 (for example, pallet assembly 30B) is arranged at the position of the pallet assembly 30 (for example, pallet assembly 30A) before the rotation. Therefore, the position of the eight pallet assemblies 30A to 30H is sequentially changed by rotating the rotary table 20 by 45 degrees in one direction.

Hereinafter, the configuration of the pallet assembly 30 will be described with reference to FIG. Since the eight pallet assemblies 30 have the same configuration, only the configuration of one pallet assembly 30 will be described, and description of the remaining pallet assemblies 30 will be omitted.

As shown in FIG. 3, the pallet assembly 30 includes a circular pallet 31, a motor (drive unit) M that rotationally drives the circular pallet 31, and two

rotation separation units

40 and 50.

The circular pallet 31 has a function as a container into which electronic components are put, and has a disc-shaped bottom plate 32 and an annular side wall 33 surrounding the outer edge of the bottom plate 32. The bottom plate 32 has a circular outer edge, and the annular side wall 33 extends upward from the circular outer edge of the bottom plate 32, and defines a corner C that is substantially perpendicular to the bottom plate 32.

The motor M rotates the circular pallet 31 from the lower side of the circular pallet 31 around the rotation axis R ₁ extending in the vertical direction. A rotation axis R ₁ of the motor M is an axis passing through the center of the disk-shaped bottom plate and a center axis of the annular side wall 33. The pallet assembly 30 is provided with an arm portion 34 having an arm 34a extending parallel to the circular pallet 31 above the circular pallet 31, and a drive shaft 35 of the motor M is pivotally supported at the tip of the arm 34a. Has been.

The rotational speed and rotational acceleration of the circular pallet 31 can be set as appropriate, but the centrifugal force acts on the electronic components put into the circular pallet 31 and the electronic components move toward the side wall 33 side. Is set.

An annular bank portion 36 is provided in the region on the bottom plate 32 of the circular pallet 31 near the rotation axis R ₁ of the circular pallet 31 so as to surround the rotation axis R ₁ . The upper surface of the bank portion 36, the distance from the axis of rotation R _1, the height from the upper surface of the bottom plate 32 is inclined to gradually lower. Therefore, when there is an electronic component on the upper surface of the bank portion 36, that fall in or rolling it slides down the inclined, the electronic component tends to move away from the axis of rotation R _1.

Therefore, by providing the bank part 36 as described above, the electronic component can easily move toward the side wall 33, and the movement of the electronic component toward the side wall 33 by the centrifugal force described above is promoted.

As shown in FIG. 4, a plurality of button-shaped convex portions 38 are provided on the upper surface of the bottom plate 32 of the circular pallet 31. The electronic component thrown into the circular pallet 31 may move by rolling or sliding, but the movement amount of the electronic component is adjusted by providing the convex portion 38. Specifically, the amount of movement of the electronic component is regulated by the electronic component coming into contact with the convex portion. The dimensions, shape, installation density, and the like of the protrusions 38 are designed so that the electronic component has a desired amount of movement. The arrangement of the convex portions 38 may be regular or random (irregular). In addition, as a method of regulating the movement amount of the electronic component, in addition to an aspect in which the convex portion 38 is provided on the upper surface of the bottom plate 32, an aspect in which the upper surface of the bottom plate 32 is in a brush shape like an artificial grass can be considered.

Here, the electronic component P put into the circular pallet 31 will be described with reference to FIG. FIG. 5 shows, as an example of the electronic component P, four types of electronic components P1 to P4 with a lead (so-called radial lead type electronic components).

The electronic component P1 has a configuration in which a pair of long leads extend from one end surface of the main body having a cylindrical outer shape. Since such an electronic component P1 has a shape that is easy to roll, it is preferable that the movement amount (rolling amount) thereof is regulated by the above-described convex portion 38 or the like.

The electronic component P2 has a configuration in which four short leads extend from one end face of the main body having a rectangular plate-like outer shape. Since such an electronic component P2 has a shape that is difficult to roll, contrary to the electronic component P1 described above, a sufficient amount of movement cannot be obtained if the above-described convex portion 38 is provided. Therefore, it is preferable not to provide the convex portion 38 on the circular pallet 31 into which the electronic component such as the electronic component P2 is put. In order to increase the moving amount (sliding amount) of the electronic component P2, it is preferable to smooth the upper surface of the bottom plate 32 of the circular pallet 31.

The electronic component P3 has a configuration in which a long lead and a short REIT extend from one end face of a main body having a rectangular parallelepiped shape. Such an electronic component P3 has a shape that is difficult to roll like the electronic component P2 described above, and does not restrict the amount of movement by the convex portion 38 or the like, but rather increases the amount of movement (sliding amount). It is preferable to employ 31.

The electronic component P4 has a configuration in which a pair of long leads extend from a main body portion having a disc-like outer shape. Such an electronic component P4, like the above-described electronic components P2 and P3, has a shape that is difficult to roll, and the bottom plate 32 that increases the amount of movement (sliding amount) without restricting the amount of movement by the convex portion 38 or the like. It is preferable to employ a circular pallet 31.

Since all of the electronic components P1 to P4 described above have leads, the leads of each component are entangled with each other and an assembly of electronic components is easily formed. In particular, when a plurality of electronic components are randomly packed for the purpose of convenience of transportation, etc., the electronic components form an assembly in the bag and remain as an assembly when taken out from the bag. There are many cases. If the electronic components remain as an assembly, it is difficult to pick them up with the chuck of the robot arm, so it is necessary to separate them into individual electronic components in advance.

The two

rotation separation units

40 and 50 are constituted by a first rotation separation unit 40 and a second rotation separation unit 50.

First, the first rotation separation unit 40 will be described with reference to FIG. The first rotating / separating unit 40 has a rotating piece (first rotating piece) 42 that rotates around a rotation axis R ₂ parallel to the vertical axis direction on the bottom plate 32 of the circular pallet 31.

The rotating piece 42 has a rectangular thin plate shape and is made of an elastic material (for example, rubber). The rotating piece 42 extends along the vertical direction, and the lower end thereof is adjusted to a height position in contact with the bottom plate 32 or a height position slightly separated from the bottom plate 32. Therefore, the rotating piece 42 can contact the electronic component P when the circular pallet 31 rotates and the electronic component P in the circular pallet 31 reaches the position of the rotating piece 42.

The rotating piece 42 is disposed at a position close to the corner C defined by the bottom plate 32 and the side wall 33 of the circular pallet 31, and the rotating piece 42 is in contact with the side wall 33 or the side wall. Slightly spaced from 33. Therefore, the rotating piece 42 can contact the electronic component P that moves together with the circular pallet 31 so as to stick to the side wall 33 of the circular pallet 31.

The shaft 44 of the rotating piece 42 is rotationally driven by the motor M1. Shaft 44 of the rotating piece 42 includes a motor M1 with parallel drive axis _{R 3} to the rotation axis _{R 2} of the rotating piece 42, via a pair of gears (spur gear) 46 and 48 are rotated connected .

The rotating direction of the rotating piece 42 is opposite to the rotating direction of the circular pallet 31. In the embodiment shown in FIG. 6, the circular pallet 31 rotates counterclockwise (counterclockwise) when viewed from above, whereas the rotating piece 42 rotates clockwise (clockwise) when viewed from above. ing. The rotating piece 42 rotates in a direction opposite to the rotating direction of the circular pallet 31, so that the electronic component P moved to the vicinity of the side wall 33 by the rotating piece 42 by the centrifugal force along the surface direction of the upper surface of the bottom plate 32. Thus, it can be flipped inward (rotation axis R ₀ side). On the other hand, when the rotating piece 42 rotates in the same direction as the rotation direction of the circular pallet 31, the rotating piece 42 directs the electronic component P in the vicinity of the side wall 33 toward the side wall 33, and as a result, the rotating piece 42 and the side wall 33. This is not preferable because the situation in which the electronic component P is involved occurs.

According to the first rotary separation unit 40 described above, the electronic component P put on the circular pallet 31 can be flipped off by the rotary piece 42. In particular, the electronic component P moved to the vicinity of the side wall 33 by the centrifugal force accompanying the rotation of the circular pallet 31 can be blown off inside the circular pallet 31. At this time, if the target to be flipped off by the rotating piece 42 is an aggregate of a plurality of electronic components P, the aggregate is separated and separated into individual electronic components P.

Next, the second rotation separation unit 50 will be described with reference to FIG. The second rotary separation unit 50 has a rotary piece (second rotary piece) 52 that rotates around a rotation axis R ₄ parallel to the horizontal axis direction on the bottom plate 32 of the circular pallet 31.

The rotating piece 52 has a rectangular thin plate shape. The constituent material of the rotating piece 52 is preferably a material having high elasticity (for example, rubber), but a material having low elasticity can also be used. Rotation piece 52 from the side of the shaft 54 extending in the horizontal direction, extend in a direction perpendicular to the rotation axis R _4, when in the rotating piece 52 is closest to the bottom plate 32 position, The position is adjusted so that the distance (separation distance) d from the lower end of the rotating piece 52 to the bottom plate 32 is lower than the height (maximum height) D of the electronic component P (that is, 0 <d <D). Therefore, when the circular pallet 31 rotates and the electronic component P in the circular pallet 31 reaches the position of the rotating piece 52, the rotating piece 52 can contact the upper end portion of the electronic component P. As a result, the rotating piece 42 can push or flip the electronic component P in the direction toward the inner side (rotation axis R ₀ side).

As shown in FIG. 3, the second rotation separation unit 50 can be disposed at a position away from the circular pallet 31 by being attached to the above-described arm 34 a via the holding plate 37. In FIG. 3, the second rotational separation unit 50 is shown attached to the lower side of the holding plate 37, but may be attached to the upper side of the holding plate 37. When the second rotary separation unit 50 is attached to the lower side of the holding plate 37, the distance d from the lower end of the rotary piece 52 to the bottom plate 32 becomes relatively short, so that low-profile parts (for example, shown in FIG. It is suitable for separation of electronic parts P3, P4). On the other hand, when the second rotation separation unit 50 is mounted on the upper side of the holding plate 37, the distance d is relatively long, so that the high-profile component (for example, the electronic component P1 shown in FIG. 5) is separated. Is suitable.

According to the second rotary separation unit 50 described above, the electronic component P put on the circular pallet 31 can be pushed by the rotary piece 52. At this time, if the object to be pressed by the rotating piece 52 is an aggregate of a plurality of electronic components P, the aggregate is separated and separated into individual electronic components P. Further, if the object to be pressed by the rotating piece 52 is an electronic component P1 in an upright posture as shown in FIG. 7, the electronic component P1 is tilted inward by pressing its upper end.

As described above, in each pallet assembly 30, the two

rotary separation units

40, 50 are each independently or the two

rotary separation units

40, 50 cooperate with each other to supply the electronic components that are put into the circular pallet 31. Separation of the P aggregate can be realized.

The pallet assembly 30 further includes an extrusion separation unit 60. Hereinafter, the extrusion separation unit 60 will be described with reference to FIG.

The extrusion separation unit 60 has an extrusion surface portion 62 that moves on the bottom plate 32 of the circular pallet 31. The extrusion surface portion 62 includes an elastic plate 64 and a holding portion 66 that holds the elastic plate 64.

The elastic plate 64 has a rectangular thin plate shape and is made of an elastic material (for example, rubber). The elastic plate 64 extends along the inner surface 33 a of the side wall 33, and the lower end thereof is in contact with the bottom plate 32. The holding portion 66 holds the elastic plate 64 and is attached to a rod of an air cylinder M3 (not shown). By actuating the air cylinder M3, the elastic plate 64 and the holding portion 66 of the extrusion surface portion 62 advance and retreat with respect to the inner side (rotation axis _R0 side) of the circular pallet 31 via the rod.

Therefore, according to the extrusion separation unit 60 described above, the electronic component P put into the circular pallet 31 can be pushed out to the inside of the circular pallet 31 by the extrusion surface portion 62. In particular, the electronic component P moved to the vicinity of the side wall 33 by the centrifugal force accompanying the rotation of the circular pallet 31 can be pushed out to the inside of the circular pallet 31. At this time, if the object to be pushed out by the extrusion surface portion 62 is an aggregate in which a plurality of electronic components P are collected, the aggregate is separated and separated into individual electronic components P.

The elastic plate 64 is not necessarily in contact with the bottom plate 32. If the height is close to the bottom plate 32 to the extent that the electronic component P can be pushed out, the elastic plate 64 is at a height position slightly separated from the bottom plate 32. May be.

A chuck region S is formed inside the extrusion separation unit 60 on the upper surface of the bottom plate 32 of the circular pallet 31. In the chuck region S, the chuck of the robot arm picks up the electronic components P one by one and mounts the electronic components P on a predetermined substrate.

The extrusion separation unit 60 has a function of transporting the electronic component P from the vicinity of the side wall 33 to the chuck region S in addition to the function of separating the assembly of electronic components into individual electronic components P.

In the chuck region S, when the chuck of the robot arm picks up the electronic component P, the rotation of the circular pallet 31 is stopped, and the extrusion surface portion 62 of the extrusion separation unit 60 is retracted to the vicinity of the side wall 33. By retreating the extrusion surface portion 62 of the extrusion separation unit 60 to the vicinity of the side wall 33, a situation in which the extrusion surface portion 62 and the chuck come into contact with each other can be avoided.

The pickup of the electronic component P by the chuck of the robot arm is performed only at the position of the pallet assembly 30A shown in FIG. In this case, the rotation of the circular pallet 31 is stopped at the position of the pallet assembly 30A.

At the positions of the pallet assemblies 30B to 30H other than the pallet assembly 30A, the circular pallet 31 rotates and the electronic parts P are separated by the

separation units

40, 50, and 60 described above. The separation of the electronic component P may be completed in the pallet assembly 30B that comes next to the position of the pallet assembly 30A by the rotation of the turntable 20.

For example, the assembly of the electronic parts P to be separated is stopped by stopping the rotation of the circular pallet 31 at the position of the pallet assembly 30H after the pickup of the electronic parts P is completed and the inside of the circular pallet is empty. Do it.

As described above, the electronic component separating apparatus 1 includes the circular pallet 31, the motor M that rotates the circular pallet 31 around the central axis (rotation axis R ₀ ) of the side wall 33, and the bottom plate 32 of the circular pallet 31.

Rotating separation units

40 and 50 having rotating

pieces

42 and 52 that rotate on top and come into contact with the electronic component P disposed on the bottom plate 32 of the circular pallet 31 are provided. The electronic device separating apparatus 1 having such a configuration does not exist in the related art and is a novel apparatus.

The electronic component separating apparatus 1 includes a first rotating / separating unit 40 and a second rotating / separating unit 50. The rotating piece 42 of the first rotating / separating unit 40 and the rotation of the second rotating / separating unit 50 are provided. With the piece 52, the directions of the rotation axes R ₂ and R ₄ are twisted relative to each other. When the directions of the rotation axes R ₂ and R ₄ are parallel to each other, the force in the same direction acts on the electronic component by the rotation of the rotating piece, whereas the directions of the rotation axes are twisted with respect to each other. In the case of the positional relationship, forces in different directions can be applied to the electronic component by the rotation of the rotating piece. In this case, various forces act on the electronic component P, and the separation efficiency of the electronic component P is improved. The direction of the rotation axis of the rotary piece is not limited to the direction parallel to the rotation axis of the circular pallet (vertical direction) or the horizontal direction, but may be other directions. The number of rotation separation units is not limited to two, and may be three or more. Even when three or more rotary separation units are used, it is preferable that the rotary pieces have a twisted positional relationship with each other.

Further, in the electronic component separating apparatus 1, the rotating piece 42 of the first rotating / separating unit 40 is disposed in the vicinity of the corner C defined by the bottom plate 32 and the side wall 33 of the circular pallet 31. At the same time, it rotates around the rotation axis R ₂ parallel to the rotation axis R ₁ (that is, the central axis of the side wall 33). Therefore, among the electronic components P put in the circular pallet 31, the electronic components P moved to the vicinity of the side wall 33 by centrifugal force can be flipped off and separated.

In the electronic device separating apparatus 1, the rotating piece 52 of the second rotating / separating unit 50 is disposed above the bottom plate 32 and rotates around the rotation axis R ₄ orthogonal to the rotation axis R ₁ . The distance d between the second rotating piece 52 and the bottom plate 32 is designed to be shorter than the maximum height D of the electronic component P disposed on the bottom plate 32 of the circular pallet 31. Therefore, the electronic component P in the circular pallet 31 can depress the electronic component P by pushing or flipping the upper end portion of the electronic component P at the position of the second rotating piece 52.

Further, the electronic component separation apparatus 1 further includes an extrusion separation unit having an extrusion surface portion 62 that is movable from the corner C of the circular pallet 31 toward the rotation axis R ₁ at a position close to the bottom plate 32. Therefore, among the electronic components P put into the circular pallet 31, the electronic component P moved to the vicinity of the side wall 33 by centrifugal force can be pushed out to the inside of the circular pallet 31 by the pushing surface portion 62.

In addition, the electronic device separating apparatus 1 is provided in an annular shape near the rotation axis R ₁ in the region on the bottom plate 32, and the bank portion (annular inclination portion) is inclined so as to become lower as the distance from the rotation axis R ₁ increases. 36 is further provided. Therefore, the electronic component P is easy to move on the bottom plate 32 toward the side wall 33 side.

Further, the electronic component separating apparatus 1 further includes a plurality of circular pallets 31, and further includes a rotary table 20 in which the plurality of circular pallets 31 are regularly arranged at equiangular intervals. The

rotary separation units

40 and 50 are attached. Therefore, the position of the circular pallet 31 of each pallet assembly 30 can be sequentially changed by rotating the rotary table 20 by a predetermined angle. Thereby, it is possible to improve the efficiency of separation processing such as separation of electronic components in some circular pallets and pick-up by a robot arm in other circular pallets.

The present invention is not limited to the above-described embodiment, and can be appropriately modified and applied without departing from the spirit of the present invention.

For example, in the electronic device separating apparatus, the number of pallet assemblies can be increased or decreased as appropriate, and for example, electronic components can be separated with only one pallet assembly. Further, the pallet assembly is not necessarily moved by a rotary table or the like, and the pallet assembly may be fixed at a fixed position to separate the electronic components.

Further, the pallet assembly does not always need to be combined with the circular pallet, the drive unit, and the rotary separation unit, and only when the electronic components in the circular pallet need to be separated, the rotary pallet is separated from the drive unit. The aspect with which a unit is combined may be sufficient. For example, only a drive unit and a rotary separation unit are installed in a predetermined separation work area, and only a circular pallet that requires separation of electronic components from a plurality of circular pallets is transferred to the separation work area. A combination with the rotary separation unit is conceivable. By reducing the number of driving units and the number of rotation separation units with respect to the number of circular pallets, the number of parts and cost can be reduced. In this case, instead of the motor M described above, a driving roller that contacts the side wall outside the side wall of the circular pallet may be employed as the driving unit.
