Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for arranging rod-shaped objects, for example, in a process of manufacturing a semiconductor device, for sequentially packing stick-shaped magazines containing semiconductor devices in a container in an aligned state. Regarding what is valid to use.

[0002]

2. Description of the Related Art Generally, in the manufacturing process of a semiconductor device, the manufactured semiconductor device undergoes a screening inspection for non-defective products by an IC handler, and the non-defective products are automatically stored in a magazine. Then, the magazines in which the semiconductor devices are stored are sequentially stored in a container using a cardboard box or the like.

Conventionally, when a magazine is packed in a container, the magazine is automatically dropped from the IC handler into the container. Then, the magazines in the container are manually arranged by the worker so as to be in a multi-stage packing state.

As an example in which the IC handler is mentioned, "Electronics November 1989 issue, separate volume", published by Kogyo Kenkyukai Co., Ltd., November 10, 1991, P163 to P16
There are seven.

[0005]

In the conventional IC handler, although the packing work of the semiconductor device in the magazine is automated, the alignment work in the container of the actual magazine is not automated. , After all,
Unnecessary operation cannot be realized because the operator needs manual work.

An object of the present invention is to provide a rod-shaped object aligning device which can automatically perform an operation of aligning rod-shaped objects.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

[0008]

The typical ones of the inventions disclosed in the present application will be outlined below.

That is, the rods are parallel to each other, and
In a bar-shaped object aligning device that is adjacently aligned and is stacked on a row of a group of bar-shaped objects aligned at a predetermined alignment location, a stacking direction of the rod-shaped materials on both sides of the alignment location A pair of lifts arranged in parallel so that they can be lifted up and down, and piston rods of the pair of lifts, which are opposed to the lifts so as to come into contact with the lifts, are arranged below the lifts. A pair of cylinder devices that are moved up and down by the expansion and contraction operation of the rod, and a pair of handling devices that are respectively hung on both the lifting tables and configured to detachably hold both ends of the rod-shaped object are provided. It is characterized by

[0010]

In the above-mentioned means, the rod-shaped object as the object to be aligned is held by the handling devices on both sides.
When a predetermined number of rods are held by both handling devices, both cylinder devices are actuated and each piston rod is shortened simultaneously. When the piston rod is shortened, both lifts are lowered simultaneously, so that both handling devices mounted on both lifts are lowered. Due to this lowering, the rod-shaped objects held by both handling devices are lowered toward the alignment place.

When the rod-like objects held by both handling devices are lowered to the alignment place and the lower ends of the handling devices come into contact with the upper surfaces of the uppermost rod-like objects stacked in multiple stages at the alignment place, the lifting platform is lifted. Is supported by the rod-shaped object through the handling device, and the descent is stopped.

When the two elevators are in a state of being supported by the rod-shaped objects already stacked in multiple stages via the handling device, the piston rods of the cylinder device are configured to be able to contact the elevators, so that both piston rods are Move away from each lift. Then, the piston rod separated from the lift table is shortened to the lowest position of the cylinder device. After that, the handling device releases the holding of the rod-shaped object to transfer the held rod-shaped object onto the uppermost rod-shaped object.

In this way, according to the above-mentioned means,
When the rod-shaped objects held by the handling device are lowered to the position of the uppermost-staged rod-shaped objects that have already been stacked in multiple stages, that is, the position where the held rod-shaped objects are transferred, the lower end of the handling device comes into contact with the uppermost-stage rod-shaped objects. As a result, it can be stopped in a self-controlled manner. Therefore, it is not necessary to additionally install a dedicated detector for detecting the position at which the rod-shaped objects held by the handling device are transferred, that is, the position of the rod-shaped objects at the uppermost stage already stacked in multiple stages.

Since the piston rod supporting the lifting table can be separated from the lifting table after the handling device is automatically stopped, it can be shortened independently of the handling device. Therefore, it suffices for the piston rod to simply reciprocate between the upper limit position and the lower limit position, regardless of the height positions where the handling device stacks the rod-shaped objects in multiple stages at the aligned positions.

As a result of the piston rod simply reciprocating between the upper limit position and the lower limit position, the cylinder detector is used as a lift drive device for the lift together with the need to attach the position detector. It can be used, and the equipment cost and running cost can be significantly reduced as compared with the case where a feed screw shaft device or the like is used.

Therefore, according to the above-mentioned means, it is possible to automatically stack the rod-shaped objects on the row of the rod-shaped object group aligned in the alignment place while aligning the rod-shaped objects in parallel to each other and adjacent to each other. Therefore, the aligning work and the multi-stage stacking work can be automatically executed without human intervention.

Air cylinder devices 53, 53 are arranged directly below the central portions of the two lifts 51, 51, and are installed upward. The piston rod 54 of the air cylinder device 53 opposes the lower surface of the lift table 51 so as to be freely abuttable. That is, the piston rod 54 of the air cylinder device 53 is not fixed to the lift table 51. Therefore, the elevating table 51 is in a state in which it can be stopped independently of the shortening operation of the piston rod 54 in its descending operation.

A real magazine 10A is provided on both the lifting platforms 51, 51.
Handling device 55 that detachably holds the front and rear ends of the

Further, since the magazine holding portion 63 is formed over the entire length of the main body 61 in the left-right direction, the holding portion 63 has a plurality of actual magazines 10A.
Are arranged in a line so that they can be held simultaneously.

The electromagnetic plunger device 64 is installed so as to face inward at the center of the lift 51.
The holding arm 60 is fixed to the tip of the output shaft 65. Therefore, the holding arm 60 is driven to move in and out by the electromagnetic plunger device 64.

Next, the operation will be described. IC handler 20
The IC1 whose electrical characteristics have been measured by the measuring unit and which is determined to be non-defective is sent to the non-defective chute by the sorting chute. Good product IC1 that slipped down in the good product chute
Is the magazine 10 waiting on the non-defective packing stage 22.
Automatically packed.

In this way, the good ICs 1 are sequentially packed in the magazine 10 on the good packing stage 22,
When a predetermined number of ICs 1 are packed in the magazine 10, the full real magazine 10A is delivered to the magazine stopper insertion stage 31 by the loading device.

Further, the empty magazine 10 is paid out by the loading device from the empty magazine holder 23 to the non-defective product packing stage 22 to which the actual magazine 10A has been discharged.
The empty magazine 10 on the non-defective packing stage 22 and the actual magazine 10 on the magazine stopper insertion stage 31
A is held by the magazine holding device 26.

When the actual magazine 10A is fixed to the magazine stopper insertion stage 31, one magazine stopper 32 is separated by the cooperative work of the upper and lower separating rods 41 and 43, as shown in FIG. Insertion path 3
6 is supplied.

Subsequently, the air 40 is jetted from the air jetting path 39 and blown onto the magazine stopper 32. The magazine stopper 32 blown with the air 40 enters the actual magazine 10A in the magazine stopper insertion path 36.
Is pushed while being automatically aligned with air in the direction of,
As shown by the imaginary line in FIG. 4A, the state is aligned with the opening 15 of the actual magazine 10A.

Moreover, since the dust (not shown) in the stopper insertion path 36 is discharged by the injection of the air 40, the inside of the stopper insertion path 36 is always cleaned, and the stopper is inserted in the stopper insertion path 36. It is possible to prevent the situation where the stopper 32 is clogged and the stopper insertion operation becomes impossible.

Then, as shown in FIG. 4B, the push rod 37 is moved forward by the air cylinder device 38. The magazine stopper 32 aligned with the opening 15 of the actual magazine 10A by blowing air 40 is pushed into the opening 15 of the actual magazine 10A by the forward movement of the push rod 37. At this time, the magazine stopper 32 is the actual magazine 10
The push rod 37 is pre-aligned between the ceiling surface of A and the saddle portion 14, and the angle of attack 37a is recessed in the tip surface of the push rod 37. Therefore, the push rod 37 mounts the magazine stopper 32 to the opening portion of the actual magazine 10A. It can be pushed in properly and quickly into 15.

The magazine stopper 32 pushed into the opening 15 of the actual magazine 10A is in a compressed and deformed state and is pressed against the inner peripheral surface of the opening 15 of the actual magazine 10A. It is possible to prevent the magazine stopper 32 from easily falling off even if the pushing force acts on the inside 32 of the magazine. A magazine stopper is automatically or manually inserted in the opening on the opposite side of the actual magazine 10A.

When the magazine stopper 32 is inserted into the opening end of the actual magazine 10A as described above, the holding of the actual magazine 10A of the magazine stopper insertion stage 31 by the magazine pressing device 26 is released and the loading device is loaded. Is delivered from the insertion stage 31 to the magazine alignment device 50 (see FIG. 3).

As shown in FIG. 2, the actual magazine 10A delivered from the magazine stopper insertion stage 31 is transferred between the front and rear handling devices 55, 55 of the magazine alignment device 50. That is, since the front and rear ends of the dispensed real magazine 10A are placed on the magazine holding portions 63, 63 of the holding arms 60, 60 of the front and rear handling devices 55, 55,
The actual magazine 10A is held by the front and rear handling devices 55, 55 while being bridged between the front and rear holding arms 60, 60.

At this time, the actual magazine 10A is in a state of being inserted between the retaining arms 56, 56 of the front and rear handling devices 55, 55, and the front and rear end faces thereof face the front and rear retaining arms 56, 56 in close proximity to each other. Because it becomes a state,
The actual magazine 10A is prevented from moving in the front-rear direction by the front and rear retaining arms 56, 56.

Magazine stopper insertion stage 3 described above
The supply of the real magazine 10A from the first magazine 1 to the magazine aligning device 50 is repeated each time the magazine stopper 32 is inserted, so that the real magazine 10 is inserted between the front and rear handling devices 55, 55 of the magazine aligning device 50.
A is transferred in sequence. As a result, as shown in FIG. 3, a plurality of real magazines 10A are arranged in a line between the front and rear handling devices 55, 55.

When a predetermined number of real magazines 10A are aligned in a line between the front and rear handling devices 55, 55, the front and rear air cylinder devices 53, 53 are actuated and the piston rods 54, 54 are simultaneously shortened. It When the piston rods 54, 54 are shortened, the front and rear lifts 5
Since both 1 and 51 are lowered at the same time, both lift tables 51 and 51
Front and rear handling devices 55, 5 respectively hung on the
5 descends at the same time. Due to this lowering, the group of actual magazines 10A held in a bridged state between the front and rear handling devices 55, 55 is lowered into the container 24.

The real magazines 10A group held between the front and rear handling devices 55, 55 are lowered into the container 24, and as shown in FIG. On the upper surface of the uppermost actual magazine group, the holding portions 6 in the front and rear holding arms 60, 60 are provided.
When the lower surfaces of 3, 63 come into contact with each other, the front and rear handling devices 55, 55 are supported by both holding arms 60, 60, so that the lowering of the elevating tables 51, 51 is stopped.

By the way, a balancer (not shown) which is approximately balanced with the load of the handling device 55 applied to the lifting table 51.
The holding arm 6 can be
The load applied to the actual magazine when 0 contacts the actual magazine can be reduced.

When the front and rear handling devices 55, 55 are supported by both holding arms 60, 60,
The piston rod 54 of the air cylinder device 53 is the lift table 5.
1, the piston rods 54, 54 are separated from the lifts 51, 51, as shown in FIG. 1 (a). The piston rod 54 separated from the lift 51 can be shortened to the lowest position of the air cylinder device 53.

In this way, in this embodiment, the position of the uppermost real magazine in which the real magazines 10A held by the handling device 55 are already stacked in multiple stages, that is, the position where the held real magazines 10A are transferred. When the holding arm 60 is lowered to the uppermost actual magazine, the holding arm 60 can be stopped in a self-controlled manner. Therefore, the actual magazine 10 held by the handling device 55
It is not necessary to additionally install a dedicated detector for detecting the position where A is transferred.

Here, since the position of the uppermost real magazine, that is, the position where the real magazines should be transferred, changes as the stacking work progresses, the structure of the dedicated detector for detecting the position is complicated. Become high grade. Further, the driving device and the controller controlled based on the detection result of the detector are complicated and high-grade. Therefore, the cost of the entire magazine aligning apparatus using them becomes extremely high. However, in this embodiment, since it is not necessary to use a detector, the cost of the magazine aligning apparatus as a whole can be suppressed low.

Since the piston rod 54 supporting the handling device 55 can be separated from the lifting table 51 after the handling device 55 is automatically stopped, it is independent from the automatic stop of the lifting table 51 equipped with the handling device 55. Can be shortened. Therefore, the handling device 55 of the piston rod 54 is the actual magazine 10.
Irrespective of the position where A is transferred into the container 24, simply reciprocating between the upper limit position and the lower limit position is sufficient.

Since the piston rod 54 simply needs to reciprocate between the upper limit position and the lower limit position, it is not necessary to attach the position detector. The cylinder device 53 can be used. As a result, the equipment cost and running cost can be significantly reduced as compared with the case where a feed screw shaft device or the like is used.

In other words, when the position where the actual magazine 10A is transferred is detected by the dedicated detector, it is necessary to stop the piston rod 54 for lowering the elevating table 51 at each detection position. Therefore, an air cylinder device that simply reciprocates cannot be adopted, and it is necessary to adopt a feed screw shaft device or the like.

On the other hand, the actual magazine 10A held by the handling device 55 is lowered to the position of the uppermost actual magazine already stacked in multiple stages, that is, the position for transferring the actual magazine 10A held, and the holding arm 60 is moved. Is stopped in a self-controlled manner by coming into contact with the uppermost actual magazine, the electromagnetic plungers 64, 6 in the front and rear handling devices 55, 55 are shown in FIG. 1B.
4 is shortened, so that the holding arms 60, 60
Are opened to the outside. When both holding arms 60, 60 are opened to the outside, the magazine holding portions 63, 63 separate from the front and rear ends of the real magazine 10A, respectively, so that the real magazine 10A is placed on top of the uppermost real magazine already stacked. It is transferred so that it can be stacked.

During this transfer operation, the actual magazine 10A
Since the front and rear end surfaces of the magazine are restricted by the retaining arms 56, 56, the magazine holder 63,
Even if 63 is detached in the outward direction, it does not follow it, and the actual magazine 10A is properly moved downward so as to be stacked on the uppermost actual magazine with the detachment of both holding parts 63, 63. It will be transferred. Therefore,
The transferred real magazines 10A group can be maintained in an appropriate aligned state, and an appropriate stacking operation can be secured on the subsequent actual transfer operations.

When the transfer is completed, the front and rear air cylinder devices 53, 53 are operated and the piston rods 54, 54 are simultaneously raised. The piston rod 54 comes first in the lifting platform 5.
When it rises to the position separated from 1, it comes into contact with the lift table 51, and thereafter, the lift table 51 is raised and stopped at the upper limit position. Lift 51
When the climbing stops, the front and rear handling devices 55, 5
5 returns to the original position facing the magazine stopper insertion stage 31. Then, the electromagnetic plunger device 64 is extended so that each holding arm 6
0 and 60 are closed inward, and both magazine holders 63 and 63 are returned to their original positions.

Thereafter, by repeating the above-mentioned operation, the actual magazines 10A are stacked in the container 24 in a multi-stage manner.

According to the above embodiment, the following effects can be obtained. (1) A pair of lifts 51, 51 are arranged on both sides of the container 24 in which the group of real magazines 10A is accommodated in an aligned state so as to be vertically movable in parallel with the stacking direction of the real magazines 10A. A pair of air cylinder devices 53 for raising and lowering the elevating table by the expansion and contraction operation of the piston rod 54 are provided under 51, and are arranged upward so that the piston rods are opposed to the elevating table so as to freely abut.
By mounting a pair of handling devices 55 and 55 that detachably hold both ends of the real magazine 10A in the containers 1 and 51, respectively, the real magazines 10A are aligned in parallel and adjacent to each other, and inside the container 24. Since the actual magazines can be automatically stacked on the rows of the actual magazines arranged in line with each other, it is possible to automatically perform the alignment work and the multi-stage stacking work of the real magazines 10A without human intervention.

(2) When the real magazine 10A held by the handling device 55 is lowered to the position of the uppermost real magazine already stacked, that is, the position where the held real magazine 10A is transferred, the holding arm 60 is moved. Since it can be stopped in a self-controlled manner by contacting the uppermost real magazine, it is not necessary to attach a dedicated detector for detecting the position where the real magazine 10A held by the handling device 55 is transferred. I'm done.

(3) Since the piston rod 54 supporting the lift 51 on which the handling device 55 is mounted can be separated from the lift 51 after the lift 51 is automatically stopped, it is independent from the stop of the lift 51. Can be shortened. Therefore, the piston rod 54 may be configured to simply reciprocate between the upper limit position and the lower limit position regardless of the position where the handling device 55 transfers the actual magazine 10A into the container 24.

(4) According to the above (2) and (3), since the air cylinder device 53 can be used as the lifting / lowering drive device of the lifting / lowering table 51 on which the handling device 55 is mounted, a feed screw shaft device or the like is used. The equipment cost can be significantly reduced as compared with the case of performing. That is, when the position where the actual magazine 10A is transferred is detected by the dedicated detector, the lifting table 5 equipped with the handling device 55 is installed.
Since it is necessary to stop the piston rod 54 for lowering 1 at each detection position, it is not possible to adopt an air cylinder device that simply reciprocates, but it is necessary to adopt a feed screw shaft device or the like. There is.

(5) The stopper insertion path 36 is arranged so as to face the opening 15 of the actual magazine 10A held by the stopper insertion stage 31, and a stopper supply for supplying one stopper to the stopper insertion path 36 The path 35 is connected to the stopper insertion path 36, and the push rod 37 is inserted into the stopper insertion path 36 so as to be movable back and forth from the side opposite to the actual magazine 10A, and the air 40 is jetted into the stopper insertion path 36 on this push rod. By opening the air injection path 39, the actual magazine 10A
When the stopper 32 is inserted into the opening 15 of the stopper 32, the air 40 is jetted from the air jet passage 39,
When the stopper 32 is blown onto the air, the stopper 32 is blown into the stopper insertion path 36 and the real magazine 10
Since it is pushed while being automatically aligned in the direction of A, and is aligned with the opening 15 of the actual magazine 10A,
After the stopper 32 is automatically aligned with the opening 15 of the actual magazine 10A, the stopper 32 can be automatically pushed into the opening 15 by the push rod 37, so that the stopper can be inserted into the magazine. Can be performed automatically without human intervention.

(6) Further, since the dust in the stopper insertion passage 36 is discharged by the air 40 injected from the air injection passage 39, the inside of the stopper insertion passage 36 is always cleaned, and the stopper insertion passage 36 It is possible to prevent the situation where the stopper 32 is clogged in the inside and the insertion work becomes impossible, which may occur.

Although the invention made by the present inventor has been specifically described based on the embodiments, the present invention is not limited to the embodiments and various modifications can be made without departing from the scope of the invention. Needless to say.

For example, the handling device, the guide device for the lift, and the cylinder device are not limited to the structure according to the above-described embodiment, but other structures can be adopted.

In the above description, the case where the invention made by the present inventor is mainly applied to the IC handler which is the field of application which is the background of the invention has been described. However, the invention is not limited thereto, and a magazine for arranging magazines is arranged. It can be applied to all alignment devices. The object to be aligned is not limited to the magazine, but may be another rod-shaped object.

[0073]

The effects obtained by the typical ones of the inventions disclosed in the present application will be briefly described as follows.

A pair of lifts are arranged on both sides of the alignment place where the rods are aligned so that they can be raised and lowered parallel to the stacking direction of the rods, and the lifts are extended and retracted on the lower side of the two lifts. A pair of air cylinder devices that are moved up and down by operation are arranged upward so that the piston rods are in contact with the lift tables so that they can freely contact each other, and a pair of handlings that detachably hold both ends of the rod-shaped object on both lift tables. By mounting the devices respectively, the rod-shaped objects can be aligned parallel to each other and adjacent to each other, and can be automatically stacked on the row of the rod-shaped objects aligned in the alignment place. Alignment work and multi-stacking work can be automatically performed without human intervention.

When the rods held by the handling device are lowered to the position of the uppermost rod which is already stacked in multiple stages, that is, the position where the held rods are transferred, the lower end of the handling device is the uppermost rod. By contacting
Since it can be stopped in a self-controlled manner, it is not necessary to attach a dedicated detector for detecting the position at which the rod-shaped object held by the handling device is transferred.

Since the piston rod supporting the lifting table equipped with the handling device can be separated from the lifting table after the handling device is automatically stopped, it can be shortened independently of the lifting table equipped with the handling device. Therefore, it suffices for the piston rod to reciprocate between the upper limit position and the lower limit position regardless of the position where the handling device stacks the rod-shaped objects in multiple stages. As a result, since the cylinder device can be used as the lifting drive device for the lifting table equipped with the handling device, the facility cost can be significantly reduced as compared with the case where the feed screw shaft device or the like is used.
