Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an object moving apparatus, and more particularly, to an IC container for automatically horizontally transferring an IC container.
The present invention relates to a device for rotating a C container 90 degrees from vertical to horizontal.

In recent years, in the manufacturing process of ICs, it has been required to manufacture a large number of ICs in a shorter time and to downsize and simplify the manufacturing apparatus. for that reason,
Even in an apparatus that performs a process of rotating an IC container 90 degrees from vertical to horizontal when the IC container is transported horizontally, it is required to shorten the processing time and downsize and simplify the apparatus.

[0003]

2. Description of the Related Art Generally, an IC container is used to carry and ship a plurality of ICs of the same type.

FIG. 14 shows a ZIP package (zig-zag in
-line package) IC 51 is shown in an IC container 52. The IC container 52 (length α, width β, height γ) is a sheath 5 made of plastic or metal (such as aluminum).
3 and a plug 54 made of plastic or rubber that seals both open ends of the sheath 53. The cross-sectional shape of the sheath 53 matches the shape of the IC to be stored (Z shown in FIG. 14).
For IC51 of IP package, rectangular cross section),
Each IC 51 is tightly packed in a sheath 53. This prevents the IC 51 from dancing inside the sheath 53 and being damaged during transportation.

When the IC container 52 is transported horizontally in a manufacturing plant, the IC container 52 must always be placed vertically. This is IC51 (especially
This is because it is necessary to keep the IC 51 upright (the lead is on the lower side) in order to prevent damage to the lead) and to facilitate feeding the IC 51 to the inspection device.

Therefore, when the IC container 52 is shipped, a process for converting the IC container 52, which has been conveyed horizontally in a vertical position, into a horizontal position (hereinafter referred to as vertical / horizontal conversion process) is required.

FIG. 15 shows a main part of a conventional apparatus for performing a vertical / horizontal conversion process and its process. In FIG. 15 (a), the IC container 52 that has been transported horizontally in a vertically placed state is
In (b), the rotary chuck 61 is held by the rotary chuck 61 in a vertically placed state. Next, in (c), the IC container 52
The rotating chuck 61 which has grasped is rotated 90 degrees clockwise to place the IC container 52 in a horizontal position. And
In (d), the IC container 52 is attached to the rotary chuck 61.
To the horizontal transfer table 62. Subsequently, the rotary chuck 61 separated from the IC container 52 is rotated counterclockwise by 90 °.
The IC that has been rotated horizontally and returned to (b), and then horizontally conveyed
Make sure to grab the container 52.

By repeating this operation, it is possible to convert the plurality of IC containers 52 that have been horizontally conveyed in the vertically placed state into the horizontally placed state.

[0009]

However, in the above-mentioned conventional apparatus, the rotary chuck 61 is used.
In order to perform the vertical / horizontal conversion processing of the C container 52, three processing steps [grab (the IC container 52 by the rotary chuck 61) → rotate → place (on the carrier 62)] are indispensable. When the vertical / horizontal conversion processing is surely performed without giving unnecessary vibration or shock to the IC 61 in the IC container 52,
There is a limit to the reduction of the time required for each processing step. Moreover, the vertical / horizontal conversion processing of the next IC container 52 cannot be started until the vertical / horizontal conversion processing of one IC container 52 is completed. Therefore, there is a problem that the time required for the vertical / horizontal conversion processing becomes long.

Further, in the conventional apparatus, since the rotary chuck 61 is rotated by 90 degrees, there is a problem that the external dimension of the apparatus is increased by the space for the rotation, which makes it difficult to miniaturize the apparatus. Further, since the mechanism of the rotary chuck 61 is complicated, the manufacturing cost of the device is high and the maintenance is not easy.

The present invention has been made to solve the above problems, and an object thereof is to carry out a process of rotating an IC container 90 degrees from vertical to horizontal when the IC container is transported horizontally. An object of the present invention is to shorten the processing time and to downsize and simplify the device.

[0012]

The catch plate is provided next to a plurality of comb teeth at equal intervals, recesses of the same width between the comb teeth, and the comb teeth at the end, and one side thereof. A comb shape is formed in which a vertical-horizontal conversion concave portion that is inclined outward with respect to each comb tooth and a convex portion that is provided next to the vertical-horizontal conversion concave portion and has a horizontal top portion are formed. The catch plate is installed horizontally.

The walking beam corresponds to a plurality of comb teeth having the same spacing as the comb teeth of the catch plate, each recess between the comb teeth and having the same width as the recess of the catch plate, and the recess for vertical / horizontal conversion. It has a comb shape in which a convex portion having a shape of The walking beam is installed parallel to the catch plate. Also,
The walking beam is adapted to move vertically and horizontally relative to the catch plate.

[0014]

Therefore, according to the present invention, when a square bar is placed in each of the recesses of the catch plate and the walking beam, the walking beam is moved vertically and horizontally to sequentially move the square bar to the catch plate. It can be moved to the recess.

Then, the square bar fitted in the vertical / horizontal conversion concave portion of the catch plate can be pushed up by the convex portion of the walking beam and placed on the top of the convex portion of the catch plate.

Here, by appropriately setting the vertical and horizontal conversion concave portions of the catch plate, the convex portions of the walking beam and the cross section of the square rod, the square rod fitted in the vertical and horizontal conversion concave portion is caught. The square bar can be laid down 90 degrees in the process of being placed on the top of the convex portion of the plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment embodying the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. In this embodiment, the IC
Since the configuration of the container 52 is the same as that of the conventional example, the same reference numerals are given and detailed description thereof is omitted.

FIG. 1 is a side view of the main part of this embodiment, and FIG. 2 is a plan view thereof. The catch plate 21 is a comb-shaped flat plate in which six comb teeth 22 are formed at equal intervals, and is installed horizontally.

The widths of the six recesses 23 between the comb teeth 22 are constant and are set to be slightly wider than the width β of the IC container 52. Therefore, the recess 23
The IC container 52 fitted in can be stably held in the vertical position without tilting.

A concave portion 24 and a convex portion 25 are formed on the right side of the rightmost comb tooth 22. Unlike the other concave portions 23, the concave portion 24 has one side 24a on the right side inclined to the right side so that the width thereof widens upward.
The bottom surface 24b of the recess 24 is also inclined to the right. Further, the upper surface 25a of the convex portion 25 is horizontal, and the width of the upper surface 25a is set to be slightly smaller than the height γ of the IC container 52. Therefore, the IC container 52 can be stably placed on the upper surface 25a in a horizontally placed state.

On the right side of the convex portion 25, a horizontal horizontal portion 26 is formed. The length of the horizontal portion 26 is IC
It is set to be larger than the height γ of the container 52. Therefore, the IC container 52 can be stably placed on the horizontal portion 26 in a horizontally placed state.

The catch plate 21 is vertically movable in the vertical direction by a mechanism (not shown). The walking beam 31 is a comb-shaped flat plate in which five comb teeth 32 are formed at equal intervals, and is installed in parallel and horizontally in proximity to the catch plate 21.

The spacing between the comb teeth 32 is the same as the spacing between the comb teeth 22 of the catch plate 21. In addition, the width of the six recesses 33 between the comb teeth 32 is determined by the catch plate 2
It is the same as the interval between the concave portions 23 of No. 1. Therefore, the recess 3
The IC container 52 fitted in 3 can be stably held vertically without tilting.

A convex portion 34 is formed on the right side of the rightmost concave portion 33, and a horizontal horizontal portion 35 is formed on the right side of the convex portion 34. The length of the horizontal portion 35 is set to be larger than the height γ of the IC container 52. Therefore, the IC container 52 is placed in the horizontal part 3
It can be stably placed on the 5 in a horizontal position.

The walking beam 31 is fixed to the lifter 41. The lifter 41 is a slider 42
On the other hand, a mechanism (not shown) vertically moves in the vertical direction (direction AA shown in FIG. 1). Further, the slider 42 is installed parallel to and horizontal to the catch plate 21, and is provided by being fitted into a slide shaft 43 fixed to the main body of the apparatus. And the slider 4
2 is horizontally moved with respect to the slide shaft 43 in the left-right direction (BB direction shown in FIG. 1) by a mechanism (not shown). The horizontal movement amount of the slider 42 depends on the catch plate 21 and the walking beam 3.
This corresponds to one interval between the comb teeth 22 and 32 (hereinafter, referred to as one pitch). That is, as shown in FIG. 1, when the leftmost comb teeth 22 and 32 are at the same position in the horizontal direction (hereinafter, referred to as a steady state), the slider 42 (walking beam 31) is horizontally moved by one pitch in the right direction. You can move. When the rightmost comb teeth 22 and 32 are at the same position in the horizontal direction, the slider 42 (walking beam 31) can horizontally move one pitch to the left and return to the steady state.

The catch plate 2 thus constructed
As shown in FIG. 2, two sets of 1 and walking beams 31 are installed in parallel and at the same height at intervals corresponding to the length α of the IC container 52. Therefore, IC container 5
2 is fitted vertically into the recesses 23 and 33, or when the IC container 52 is attached to the horizontal parts 26 and 35.
Or, when riding horizontally on the upper surface 25a, the IC
The container 52 is horizontal.

The horizontal portion 26 of each catch plate 21.
As shown in FIG. 2, belt conveyors 44 are installed on the outside of each of the above. The height of each belt conveyor 44 is set to be slightly higher than the height of the horizontal portion 26 of each catch plate 21 in the steady state. Therefore, the IC container 52, which is placed on the horizontal portion 26 of the catch plate 21 in the horizontally placed state, can be horizontally conveyed by the belt conveyor 44 while being placed horizontally.

Next, the operation of the present embodiment configured as described above will be described with reference to FIGS. First, the catch plate 21 moves upward, and the IC (not shown)
A maximum of six IC containers 52 are supplied from the container supply mechanism. IC supplied from IC container supply mechanism
The container 52 is fitted into each recess 23 sequentially from the rightmost recess 23 of the catch plate 21. Then, the catch plate 21 moves downward and enters the steady state shown in FIG. Note that FIG. 3 shows a case where two IC containers 52 are supplied to the catch plate 21 from the IC container supply mechanism.

Then, as shown in FIG. 4, the lifter 41 moves upward. Then, each IC container 52 comes off from each recess 23 of the catch plate 21 and fits into each recess 33 of the walking beam 31.

Next, as shown in FIG. 5, the slider 42 is moved one pitch from the steady state to the right while the lifter 41 is still moved upward. Then, as shown in FIG. 6, the lifter 41 moves downward while the slider 42 keeps moving one pitch to the right from the steady state. Then, each IC container 52 is disengaged from each recess 33 of the walking beam 31, and fitted into the recess 23 and the recess 24 on the rightmost side of the catch plate 21. Since the bottom surface 24b of the recess 24 and the right side 24a are inclined to the right, the IC container 52 fitted in the recess 24 is also inclined to the right along the side 24a.

Subsequently, as shown in FIG. 7, the slider 42 is moved rightward by one pitch while the lifter 41 is moving downward, and the slider 42 is returned to the normal state. Next, as shown in FIG. 8, the lifter 41 moves upward. Then, the lower end of the IC container 52 fitted in the concave portion 24 is pushed up by the convex portion 34 of the walking beam 31, and the IC container 52 is obliquely lifted while engaging with the end surface of the convex portion 25 of the catch plate 21.

Then, as shown in FIG. 9, when the lifter 41 moves further upward, the recesses 23 and 33 of the catch plate 21 and the walking beam 31 completely overlap each other. Then, the IC container 52 fitted in the recess 24 comes out of the recess 24, and the catch plate 21
It rides on the upper surface 25a of the convex portion 25 in a horizontal state.

Then, as shown in FIG.
When is moved further upward, the IC container 52 fitted in the rightmost recess 23 of the catch plate 21 is disengaged from the recess 23 and fitted into the rightmost recess 33 of the walking beam 31. Also, the catch plate 21
IC that was placed on the upper surface 25a of the convex portion 25 in a horizontal state
The container 52 disengages from the convex portion 25 and rides horizontally on the horizontal portion 35 of the walking beam 31.

Then, as shown in FIG. 11, the slider 42 is moved one pitch from the steady state to the right while the lifter 41 is kept moving upward. Then, as shown in FIG.
The lifter 41 moves downward while the slider 42 keeps moving one pitch to the right from the steady state. Then, the IC container 52, which has been horizontally placed on the horizontal portion 35 of the walking beam 31, is disengaged from the horizontal portion 35 and is horizontally placed on the horizontal portion 26 of the catch plate 21. Also,
The IC container 52 fitted in the rightmost recess 33 of the walking beam 31 comes out of the recess 33 and fits in the recess 24 of the catch plate 21. The recess 24
Since the bottom surface 24b and the right side 24a are inclined to the right, the IC container 52 fitted in the recess 24 is also inclined to the right along the side 24a.

Then, as shown in FIG.
While moving downward, the slider 42 moves rightward by one pitch and returns to the steady state. Then, the IC container 52, which is placed on the horizontal portion 26 of the catch plate 21 in a horizontally placed state, is horizontally conveyed by the belt conveyor 44 shown in FIG.

After that, by repeating the above operation,
The IC container 52 fitted in the recess 24 of the catch plate 21 can be placed horizontally on the horizontal portion 26 of the catch plate 21 and horizontally conveyed horizontally by the belt conveyor 44.

As described above, in the present embodiment, the concave portion 2 of the catch plate 21 is moved by the simple operation of the walking beam 31 moving vertically and horizontally.
The IC container 52 that is vertically fitted to the No. 3 can be sequentially moved to the recess 23 on the right side. And IC
The container 52 can be placed horizontally on the horizontal portion 26 from the concave portion 24 of the catch plate 21 through the upper surface 24a of the convex portion 24, and can be horizontally conveyed by the belt conveyor 44 in the horizontal state.

Therefore, when the vertical / horizontal conversion processing of one IC container 52 is being performed, the vertical / horizontal conversion processing of the next IC container 52 is sequentially performed simultaneously, so that the vertical / horizontal conversion processing is required as compared with the conventional example. The time can be shortened.

Since the space for moving the walking beam 31 is smaller than the space for moving the rotary chuck 61 of the conventional example, the apparatus can be downsized accordingly.

Further, since the mechanism for moving the walking beam 31 (the lifter 41, the slider 42, the slide shaft 43) is simple, the manufacturing cost of the device can be kept low and the maintenance becomes easy.

The present invention is not limited to the above-described embodiment. For example, not only the IC container 51 for the ZIP package but also ICs of other shapes (SIP, DIP, etc.).
It may be applied to containers. Also, catch plate 2
The number of recesses 23 and 33 of 1 and the walking beam 31 is not limited to six. Further, it may be used not as a vertical / horizontal conversion device for an IC container, but also as a vertical / horizontal conversion device for other objects (wood, square bars such as metal, stick-shaped food, etc.).
