Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a mechanism for distributing electronic components to two or more locations while the electronic components are being transported along a rail.

[Background of the idea]

Conventionally, one of the following methods has been used to distribute electronic components to two or more locations during transportation.

(b) A method of transporting electronic components while separating them individually using a free-sliding handler, and then sorting them out.

(b) Grip the electronic components individually with the magic hand,
How to transfer and distribute.

However, in the free sliding method of (a) above, there is a risk of electronic components colliding with each other and being damaged or deformed, and the magic hand of (b) above is complicated and expensive, and in addition, it is difficult to increase work efficiency. The disadvantage is that it is difficult to

As a measure to eliminate the above drawbacks, the first
A distribution rail mechanism as shown in the figure can be considered.

Two parallel receiver rails 1, 2 are provided along two parallel axes A-A', B-B', and one supply rail is provided along an axis C-C' parallel to these. 3 will be provided. Further, a distribution rail 4 is provided which reciprocates between the A-A' axis, the B-B' axis and the C-C' axis. This distribution rail 4 is moved from the position (A) where it connects to the supply side rail 3 by the arrow a as shown by the solid line.
It moves in parallel in the direction of arrow b to reach the position (b) where it is connected to the receiving side rail 1, and it moves parallel in the direction of arrow b to the position where it connects to the receiving side rail 2 (c).

A large number of electronic components (for example, IC 5) are placed on the supply side rail 3. For convenience of explanation, IC5a, IC5b, IC5c are named and distinguished from the top in the order of conveyance. Send these ICs to the left side of the diagram. For convenience of explanation, the conveyance direction (left side) will be referred to as the front.

When the first IC5a gets on the distribution rail 4,
The distribution rail 4 is moved in parallel in the direction of the arrow a or arrow b, and connected to the receiving side rail 1 or 2 at the (b) position or (a) position.

In this way, when the distribution rail 4 is moved in parallel at right angles to the conveyance direction as shown by the arrows a and b, the ICs 5a, 5b, and 5 that have moved forward on the supply side rail 3 are
c... can be sequentially distributed to any receiving side rail 1 or 2.

However, the sorting mechanism shown in FIG. 1 has the following drawbacks. From the state shown by the solid line in Figure 1, move the distribution rail 4 to arrow a or arrow b.
When the leading IC 5a is conveyed laterally perpendicular to the forward direction, the leading IC 5a is separated from the trailing IC 5b while being rubbed against it.

Since the outer peripheral surface of the IC has irregularities such as burrs, there is a risk that tension may occur during the above-mentioned friction, leading to damage or deformation. In addition, even if there is no tension, it can become charged due to friction, and electronic components (ICs in this example)
There is a risk of electrostatic damage.

[Purpose of invention]

This idea was created in view of the above circumstances.
We have improved the distribution rail type distribution mechanism, which has no risk of damage due to collisions, has a simple configuration, and has high work efficiency, to create a distribution mechanism that does not have the risk of causing troubles due to friction (pulling or electrostatic damage). This is what we are trying to provide.

[Summary of the idea]

In order to achieve the above object, the distributing mechanism of the present invention is such that the distributing rail is moved diagonally forward in parallel from the position where it connects to the supply side rail, and is moved away from the supply side rail in an oblique direction (obliquely with respect to the transport direction). The invention is characterized in that it is provided with means for guiding and driving it so that it is spaced apart from the receiving side rail and connected to the receiving side rail.

[Example of idea]

Next, one embodiment of the present invention will be described with reference to FIGS. 2 and 3.

FIG. 2 is a perspective view showing an example of a sorting device constructed by applying the present invention, in which ICs 5a and 5b are fed in the direction of chain arrow C by a supply side rail 3'. 1' and 2' are receiving side rails.

4' is a distribution rail according to the present invention, which is fixed to the slide block 15.

The slide block 15 described above is operated by a slide shaft 7 fixed to the distribution block 6.
It is slidably supported in the conveyance direction, that is, in a direction parallel to the supply side rail 3' and the receiving side rails 1' and 2', and is biased in the backward direction (to the right in the figure) by a spring 8.

The sorting block 6 is supported by a sorting guide shaft 9 so as to be slidable in the directions of arrows a and b, that is, in a direction perpendicular to the conveying direction.

A cam follower 10 is attached to the above-mentioned distribution rail 4'.
, and the corresponding cam 11 is installed.

The above cam follower 10 is constructed using pairing. Further, the above cam 11 is provided with a shallow V-shaped tracing surface formed by a line r going diagonally to the left and a line l going diagonally to the left compared to the forward direction (arrow C). , installed on a fixed part of the device.

The cam follower 10 is pressed against the tracing surface of the cam 11 by the biasing force of the spring 8. For this reason, the distribution block 6 is moved from the position shown by the arrow a
When the distribution rail 4' is moved in the direction, the distribution rail 4' moves in parallel in the direction of the vector sum of arrow a and arrow _c1 . Third
The figure is a plan view schematically showing this embodiment, and the direction of the vector sum is represented by an arrow a' pointing diagonally forward to the right.

Similarly, when the distribution block 6 is moved in the direction of arrow b in FIG. 2, the distribution rail 4' is translated diagonally forward to the left as indicated by arrow b' in FIG.

In this way, the distribution rail 4' of the present embodiment is translated diagonally forward in the transport direction from the position (A') where it is connected to the supply side rail 3', and is moved in parallel to the position where it is connected to the receiving side rails 1' and 2'. It is guided as shown by arrows a' and b' to reach (b') and (c'), and is driven to reciprocate along arrows a' and b' (the driving means are not shown). However, it is sufficient to drive the distribution block 6 back and forth in the directions of arrows a and b).

Therefore, distribution block 4' is the first IC5.
When carrying IC 5a and moving in parallel in the direction of arrow a' or arrow b', there is no risk that the leading IC 5a will rub against the following IC 5b.

As shown in FIG. 1, when the sorting rail 4 moves in the directions of arrows a and b perpendicular to the conveying direction, the leading IC 5a riding on the sorting rail 4 and the following
Friction occurs between the IC 5b and the distribution rail 4', but since the distribution rail 4' of this embodiment moves diagonally forward in parallel as shown by the arrows a' and b' shown in FIG. The first IC5a I rode on and the following IC
5b, there is no risk of friction or tension occurring. Therefore, there is no risk of damage or deformation due to tension or electrostatic breakdown due to frictional electricity.

[Effect of idea]

As described in detail above, according to the sorting mechanism of the present invention, it is possible to construct a sorting rail-type sorting device that is free from problems such as damage, deformation, and electrostatic breakdown due to friction.
