DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray for accommodating and transporting components, and more particularly to a tray for transporting and storing components such as ICs and automatically mounting components on a substrate or the like. Regarding trays that can be used.

[0002]

2. Description of the Related Art FIG. 15 shows an example of a conventional tray. The tray 100 has, on its upper surface, pockets 101 for accommodating electronic components arranged in a matrix with a plurality of rows and a plurality of columns. Also, on the upper surface, pocket 101
And a plurality of position detection holes 102 arranged with a predetermined positional relationship.

FIG. 16 schematically shows an electronic component mounting system which has been widely used in the past.
Reference numeral A in the figure indicates a mounting portion, and electronic components required in the mounting portion A are mounted on a board or the like of an electronic device. On the upstream side of the mounting section A, a handler section B is installed. In a region E of the handler section B, a tray 10 containing electronic components is provided.
0s are stacked in many stages. The handler section B has an X guide rail and a Y guide rail (not shown).
A handler device (not shown other than the head portion C) having a head portion C that moves in the X and Y directions in FIG.

[0004] The handler is provided with a position detecting hole 1 of the tray 100.
02 is detected by a sensor device (not shown), the head unit C is moved to a predetermined XY coordinate based on the position information, and thereafter, the head unit C is moved in the Z direction (the direction normal to the paper surface). The electronic components housed in the container are sucked and taken out. Head part C of handler that has picked up electronic components
Locates the electronic component under the positioning table F, and the positioning table F sends the electronic component to the mounting section A. The empty tray 100 from which the electronic components have been taken out of the pockets 101 is accommodated in an empty tray accommodating portion D upstream of the handler portion B by a dedicated discharge arm (not shown).

In the conventional handler, as described above, it is necessary to move the head C in three directions of XYZ. Since the operation of the head portion C in each direction cannot be performed in synchronization with each other, there is a problem that the working efficiency cannot be sufficiently improved. Further, in order to increase the positioning accuracy of the head portion C, it is necessary to increase the rigidity of the guide rail. However, in this case, the size and weight of the guide rail and its driving mechanism are increased, and the shape is complicated. As a result, the cost of the entire apparatus is increased. In addition, during the tray replacement operation after one tray is emptied, the mounting operation of the electronic components must be temporarily stopped, and this also causes a reduction in work efficiency.

Further, as shown in FIG. 15, a conventional tray is configured such that a large number of electronic components (usually about 20) are accommodated in one tray. Therefore, when a small quantity shipment for sample donation or a shipment for fractional delivery is performed in accordance with a customer's request, it is necessary to ship in a state where several electronic components are stored in one tray. , Which is a waste of logistics costs.

The protrusion 13 extends in the longitudinal direction L, and the protrusion 14 extends in the transverse direction T, and positions the mold 51 of the electronic component 50 in the transverse direction T and the longitudinal direction L.

As shown in FIGS. 2 and 3, on the lower surface 4 of the tray body 2, a pair of convex portions 15 extending in the longitudinal direction L and a pair of convex portions extending in the transverse direction T are provided. 16 are formed. When the trays 1 are overlapped, the projections 15 and 16 abut against the side walls 11 of the pockets 10 of the tray 1 located below, and the trays 1, 1 overlapped with each other are moved in the transverse direction T and the longitudinal direction L. Relative to each other.

On the lower surface 4 side of the tray body 2, a pair of convex portions 17 extending in the longitudinal direction L,

The shape of each tooth 30 is equal to each other. The shape of the teeth 30 is substantially the same as the shape of the square or rectangular parallelepiped groove 38 defined between the adjacent teeth 30. That is, the shapes of the teeth 30 and the grooves 38 are complementary. The width of the teeth 30 in the longitudinal direction L and the width of the rectangular grooves 38 in the longitudinal direction L are substantially equal to の of the pitch p2 of the teeth 30. However, it is needless to say that the grooves 38 are small enough to fit the teeth 30 into the grooves 38.

The shape and dimensions of the convex portions 32 and 34 are the same. Each tooth 30 provided on the first side surface 6A is
Each of the trays 1 and 1 is engaged with each tooth 30 provided on the side surface 6B as shown in FIG.
When the projections 32 and 34 are connected to each other, the projections 32 and 34 are formed on the tooth surfaces 31 and 33, respectively.
The trays 1 and 1 are engaged with each other and restrain the relative movement of the trays 1 and 1 connected to each other in the vertical direction.

The surface shape of each tooth surface is not limited to the one shown in the figure. The tooth surface on the second side surface 8A and the tooth surface on the second side surface 8B connect the trays 1 to each other. In this case, the trays 1 and 1 only need to have complementary surface shapes (irregularities) that can restrict the relative movement of the trays 1 and 1 in the vertical direction. Further, it is not always necessary to provide unevenness on all tooth surfaces, and unevenness may be formed only on a specific tooth surface.

A specific tooth 3 among the plurality of teeth 30
0 tooth surface 31 or tooth surface 33, a semi-cylindrical recess 35
Are formed. Hereinafter, in this specification, the depression 35
When it is necessary to particularly distinguish the tooth on which the is formed, the tooth is referred to as a tooth 30a.

The teeth 30a provided on the first side surface 6A include:
A semi-cylindrical depression 35 is formed in the tooth surface 31 on one side in the longitudinal direction L, that is, the tooth surface 31 on the second side 8A side, and the tooth 30a provided in the first side surface 6B has another tooth 30a in the longitudinal direction L. Tooth surface 33, ie, tooth surface 3 on the second side surface 8B side
3, a semi-cylindrical depression 35 is formed.

As shown in FIG. 4, the tooth surfaces 31 and 33 where the depressions 35 of the teeth 30a are formed are located on a straight line passing through the center C of the pocket 10 and extending in the transverse direction T. Therefore, when the trays 1 and 1 are connected in the transverse direction T, the tooth surfaces 3
The depressions 35, 35 formed in the first and the third 33, respectively, are combined to form a cylindrical hole 36. As shown in FIG. 4, the center of the hole 36 is located at the midpoint of a line connecting the centers C and C of the pockets 10 and 10 near the holes 36 of the trays 1 and 1 connected to each other in the transverse direction T. The position of the center of the hole 36 coincides with the position of the center of the pocket 10 in the longitudinal direction L.
This hole 36 can be conveniently used as a position detection hole when trays are connected to each other, as described later.

The shape of the hole 36 formed when the teeth 30a are combined with each other is not limited to a cylindrical shape, but may be square, rectangular or rhombic as shown in FIGS. 7 (a) and 7 (b). It may be a prismatic hole having a cross section.

In this embodiment, the holes 36 are formed by two holes.
Although the teeth 30a are formed so as to straddle the teeth, the present invention is not limited to this, and a hole may be formed substantially at the center of the teeth as shown in FIG. In this case, when the trays are connected to each other in the transverse direction T,
Preferably, the holes are equidistant from the centers of pockets on one and the other trays adjacent to the holes. Also in this case, the hole can be conveniently used as a position detection hole.

Further, in the present embodiment, the shape of the teeth is rectangular when viewed from the upper surface 3 side, but is not limited to this, and as shown in FIGS. 9 (a) and 9 (b). Alternatively, the shape may be a trapezoid or a triangle when viewed from the upper surface 3. Also in this case, it is preferable that the positional relationship between the hole 36 and the pocket 10 has the same relationship as that shown in FIG. Further, it is preferable that complementary irregularities are formed on the tooth surfaces that mesh with each other.

A trapezoidal concave portion 41 is formed in the second side surface 8A as viewed from the upper surface 3. On the side surface 8B opposite to the second side surface 8A, a convex portion 42 engageable with the concave portion 41 is formed. By engaging the concave portion 41 of one tray 1 with the convex portion 42 of the other tray 1, as shown in FIG.
The trays 1 and 1 can be connected to each other in the longitudinal direction L.

Here, as shown in FIG.
The distance between the center C of the pocket 10 near B and the second side surface 8B and the distance between the center C of the pocket 10 closest to the second side surface 6A and the second side surface 8A are different between the pockets 10 adjacent to each other. The distance is equal to 1/2 of the pitch p1. Therefore, when trays 1 and 1 are connected,
The pocket 10 closest to the second side surface 6B of one tray 1
And the center C of the pocket 10 closest to the second side surface 6A of the other tray 1 is equal to the pitch p1. Therefore, when a plurality of trays 1 are connected in the longitudinal direction L, the pockets 10 of each tray 1 are arranged at equal intervals in the longitudinal direction L with a pitch p1. Note that the technique for establishing the above relationship is not limited to the above.

As shown in FIG. 4, the second side surface 8B
And the tooth surface 33 of the tooth 30 provided at the position closest to the second side surface 8B on the side of the first side surface 6A. The second side surface 8A coincides with the tooth surface 31 of the tooth 30 provided at the position closest to the second side surface 8A on the first side surface 6B side. Therefore, when a plurality of trays 1 are connected in the longitudinal direction L, the teeth 30 of each tray 1 are arranged at equal intervals in the longitudinal direction L with a pitch p2.

Hereinafter, a method of using the tray having the above configuration will be described.

[Packing of Electronic Parts] FIG. 10 is a view showing a state in which electronic parts are packed. Electronic components are stored in each pocket 10 of each tray 1. A plurality of trays 1 (two in this example) are connected to each other in the longitudinal direction L and the transverse direction T, and a plurality of (6 in this example) are vertically stacked. These trays are preferably fixed to each other by a band 9.
The details of the connected state of the trays in the horizontal direction and the stacked state in the vertical direction are described in FIGS. 2 to 4 referred to above.

The uppermost tray 1 does not contain electronic components, and the uppermost tray 1 stores the electronic components contained in each pocket 10 of the second tray 1 from the top. In a predetermined position. As described above, since the through hole 22 is formed in the tray 1, the type of the electronic component 50 can be confirmed through the through hole 22. The trays 1 can be freely connected in the longitudinal direction and the transverse direction, and can be stacked in the vertical direction, so that the tray 1 can be used for packaging from a small lot to a large lot. Further, the form of the tray assembly can be freely changed.

[Mounting of Electronic Parts] Next, FIGS.
With reference to FIG. 3, a method of mounting the electronic components 50 stored in the tray 1 will be described. First, an apparatus used for the mounting operation will be described with reference to FIG.

The feed driving device 60 takes out the tray 1 accommodated in the loader magazine 90 and sends it to a position directly below the head 91 of the handler indicated by a two-dot chain line in FIG.
To the unloader magazine 92.

A plurality of tray holding rails 94 are provided inside the loader magazine 90 and the unloader magazine 92, respectively. Tray 1 holds each rail 94
, And are stacked in the loader magazine 90 and the unloader magazine 92 at predetermined intervals in the vertical direction. Loader Magazine 9
The 0 and the unloader magazine 92 are vertically movable by a driving device (not shown).

The feed driving device 60 has a pair of guide rails 62 and 64 extending parallel to each other. The guide rail 62 is immovable with respect to the base 61, while the guide rail 64 can be adjusted in position so that the width between the guide rails 62, 64 can be adjusted. On the surface of the guide rail 62 facing the guide rail 64,
A pair of guide projections 66, 66 are provided. The guide protrusions 66 extend in the longitudinal direction in parallel with each other at an interval slightly larger than the thickness of the tray 1 and form a guide groove 67 therebetween. Also, the guide rail 64
A guide groove 68 having a width slightly larger than the thickness of the tray 1 is formed on a surface facing the guide rail 62. The guide groove 68 extends parallel to the guide groove 67. A slit 69 extending in the longitudinal direction of the guide rail 62 is formed at the bottom of the guide groove 67 of the guide rail 62.

The feed driving device 60 includes a pulse motor 70, a feed screw 71 driven by the pulse motor 70, and a feed nut 72 screwed to the feed screw 71.
And a linear drive mechanism (linear motion mechanism) having the following.
A rod 73 is fixed to the feed nut 72, and a pair of chucks 74, 74 are fixed to the rod 73 at predetermined intervals. Each chuck 74 has a tooth 30 on the first side surface 6A (or 6B) of the tray 1 respectively.
A pin 75 is provided which can engage the groove 38 between the and the teeth 30 without any gap. Each pin 75 is inserted into a slit 69 formed in the guide rail 62, and is movable toward and away from the tray 1 passing between the guide rails 62 and 64. The pin 75 is guided by the slit 69 and can move in the longitudinal direction of the guide rail 62 by operating the linear driving device. At the end of the rod 73 on the unloader magazine 92 side, a tray is attached to the unloader magazine 92.
A push-in pin 76 for pushing into the device is mounted via an L-shaped plate 77.

At the upstream end of the guide rails 62 and 64, a supply roller unit 80A for feeding the tray 1 to a position where the pins 75 of the chuck 74 can be engaged is provided. Also, at the downstream ends of the guide rails 62 and 64,
A delivery roller unit 8 for receiving the tray 1 from the chuck 74 and sending it out to the unloader magazine 92 side
0B is provided. The roller unit 80A has two drive rollers 81 and two driven rollers 82. Driving roller 81 and corresponding driven roller 82
And the tray 1 passes between them. Each drive roller 81 is driven by a servo motor (not shown) via a belt 83. The configuration of the roller unit 80B is as follows.
The configuration is substantially the same as the configuration of the roller unit 80A.

A draw-out roller unit 85 is provided between the supply roller unit 80A and the loader magazine 90 to pinch and pull out the tray 1 from the loader magazine 90 and deliver it to the supply roller unit 80A.
The pull-out roller unit 85 is provided with a pair of drive rollers 8 arranged at substantially the same interval as the width of the tray in the transverse direction.
6, 86. These drive rollers 86 can move forward and backward in the longitudinal direction of the guide rails 62 and 64.

The above-described handler 91 includes the guide rail 6
A sensor device 95 for detecting passage of the tray 1 is provided immediately below the central portion of the tray 2 or 64.

Next, a method of taking out and mounting the electronic components 50 stored in the tray 1 using the above-described apparatus will be described.

First, the drive roller 86 of the pull-out roller unit 85 moves forward to clamp the first side surface of the tray 1 housed in the loader magazine 90 with a part thereof protruding.
Next, the drive roller 86 rotates to transfer the tray 1 to the supply roller unit 80A (see the left side of FIG. 13A).

The supply roller unit 80A sends the tray 1 downstream, and the tray 1 is inserted into the guide grooves 67 and 68. When the tip of the tray 1 reaches the sensor device 95, the supply roller unit 80A stops operating. Next, the pin 75 of each chuck 74 advances toward the tray 1 and engages with the groove 38 at a predetermined position on the first side surface of the tray 1 (see the central portion in FIG. 13A). In this case, the tray 1 always stops at a predetermined position, and the chuck 74 also holds the tray 1 at the predetermined position. Therefore, the pins 75 of each chuck 74 always engage with the same groove of the tray. .

The chuck 74 holding the tray 1 is driven by a linear motion mechanism having a pulse motor 70 to move the tray 1 downstream (to the right in FIGS. 13A and 13B). At that time, the chuck 74 is attached to each pocket 1 of the tray 1.
0 is sequentially stopped immediately below the head 91 of the handler.
The head 91 of the handler sequentially sends out the electronic components 50 stored in the respective pockets 10 of the tray 1 to the positioning table F schematically shown in FIG. The positioning table F sends the electronic component 50 to the mounting section A schematically shown in FIG. 12, where the mounting of the electronic component 50 is performed.
The configurations of the positioning table F and the mounting section A are the same as those of the conventional one.

Here, the groove 38 of the tray 1 and the pocket 10
Has a certain rule as described above, and the pin 75 of each chuck 74 always engages with the same groove 38 of the tray 1 as described above. For this reason, once the pin 75 of each chuck 74 is engaged with the tray 1 once,
By simply feeding the chuck 74 by a predetermined amount without detecting the position of the electronic component 50 and the position of the pocket 10 each time, the predetermined pocket 10 can be accurately positioned in the handler head 91.
Can be located directly below.

When the last part of the tray 1 is taken out by the handler (see the center part of FIG. 13B), the chuck 7
4 feeds the tray 1 to a position where the tray 1 is nipped by the rollers of the feed roller unit 80B. Then, the pin 75 is retracted, and the chuck 74 releases the tray 1 by retracting the pin 75. Next, the delivery roller unit 80B moves the tray 1 to the unloader magazine 92.
Plug in. Thus, the tray 1 is inserted into the unloader magazine 92 about halfway (see the right side of FIG. 13A). The tray 1 that is not completely accommodated in the unloader magazine 92 is completely moved to the unloader magazine 92 by the push pin 76 that moves in conjunction with the chuck 74 when the chuck 74 holds the next tray 1 and moves to the downstream side. (See the right side of FIG. 13B).

When one tray 1 is emptied, the loader magazine 90 moves up to a position where the draw-out roller unit 85 can take out the next tray 1. Then, the above steps are repeated.

As described above, the movement of the head 91 of the handler can be simplified by using the tray according to the present embodiment. That is, the head 91
It suffices if it can realize a reciprocating motion between a predetermined position between the guide rails 62 and 64 and the positioning table F and a vertical motion. For this reason, the configuration of the handler can be simplified.

Since this position detection hole has a predetermined positional relationship with each pocket 10 of each connected tray 1, by using this position detection hole, a method similar to that described in the related art can be used. Electronic components can be mounted.

In the above embodiment, teeth and grooves are formed on the entire surface of the first side surface of the tray, and these tooth grooves are
It is used as a gripped portion of a tray feed drive device and is used as a means for connecting trays. However, in some cases, they can be arbitrarily combined according to the number of parts to be accommodated, and only need to achieve the purpose of reducing logistics costs. In such a case, complementary irregularities that can be engaged with each other may be provided on both side surfaces of the tray 1 instead of the teeth and grooves shown in the above embodiment. A preferred embodiment in that case is shown in FIG.
It is shown in FIG. The tray 1 shown in FIG. 14 has a T-shaped projection 45 extending in the longitudinal direction L on the first side surface 6A and a T-shaped projection 45 extending in the longitudinal direction on the first side surface 6B instead of the teeth 30 and the grooves 38 of the above embodiment. The difference is that a mold groove 46 is provided. When it is desired to connect a plurality of trays 1 to each other in the transverse direction T, the protrusion 45 of one tray 1 and the groove 46 of the other tray 1 may be engaged.

In the present embodiment, the object to be stored and transported in the tray 1 is an electronic component. However, the present invention is not limited to this. The tray is used for storing and transporting small mechanical parts and the like. Can also be applied. That is, the types of components to be stored and transported by the tray according to the present invention are not limited to specific types.
