Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to an IC magazine storage device that can be used in IC test equipment, automatic ROM writers, etc.

"Prior Art" In an IC test device or an automatic ROM writer (hereinafter, the IC test device will be explained as an example), the IC under test 2 is stored in a rod-shaped magazine 1 as shown in FIG.
The magazines 1 are arranged and supplied to the testing device 3 as shown in FIG. 8.

The IC testing device 3 transports the tested IC 2 to the IC discharge port 4 and stores the IC 2 into the magazine 1 again. IC2
are discharged separately from the discharge ports for non-defective products and defective products, sorted into non-defective products and defective products, and taken into the magazine 1.

FIG. 9 shows a schematic structure of a conventional magazine storage device 5. As shown in FIG. In the figure, 6 is the empty magazine storage area, and 7 is the IC
An IC-containing magazine storage part is shown that stores a magazine with an IC 2 stored at the ejection port 4. The IC discharge port 4 of the IC testing device 5 is located below the empty magazine storage section 6, and the IC 2 is loaded into the empty magazine 1 at this position.

The magazine 1 located at the IC ejection port 4 is supported by a carrier 8. The transport platform 8 has a lift section 8A that moves vertically and a slide section 8B that moves laterally. When receiving an empty magazine 1 from the empty magazine storage section 6, the lift section 8A moves upward and removes the empty magazine. At this time, the latch provided at the lower end of the magazine storage section 6 is released and the empty magazines are temporarily lifted up into the lift section 8.
Place it on top of A. The lift part 8A is lowered by an amount corresponding to one magazine 1, and in this state, the second magazine 1 from the lower end is latched, and the weight of the magazines above the second one is borne by the latch means. In this way, the lift section 8A causes the empty magazine 1 to face the IC ejection port 4.

At this position, when the magazine 1 receives the IC2 ejected from the test device 3 and becomes full with IC2, the slide part 8B moves laterally and moves the magazine 1 to the IC2.
Move it to the lower side of the magazine storage section 7. The lift section 8A moves upward while being positioned below the IC-containing magazine storage section 7, and at this time, the latch means provided at the lower end of the magazine storage section 7 is released to open the loading path for the magazine 1. Push the carried magazine in from the bottom of the IC-containing magazine storage section 7 and apply the latch again to store the magazine 1 in the IC-containing magazine storage section 7.

In this way, conventionally the IC was removed from the empty magazine storage section 6.
The magazine 1 is moved to the input magazine storage section 7.

"Problems to be Solved by the Invention" In the conventional magazine storage device 5, the empty magazine storage section 6 and the IC-loaded magazine storage section 6 correspond to each other on a one-to-one basis. Therefore, in order to increase the storage capacity of the magazine 1, the height of the magazine storage section must be increased.

If the height of the magazine storage sections 6 and 7 is increased so that many magazines 1 can be stored therein, the total weight of the magazines will increase, and unreasonable force will be applied to the mechanism.

In particular, when receiving one magazine 1 from the empty magazine storage section 6 and when storing the magazine 1 in the magazine storage section 7, the transport platform 8 does not receive the weight of all the magazines 1 that are temporarily stacked. must not.

For this reason, it is necessary to increase the height of the magazine storage sections 6 and 7, and to increase the strength of the transport platform 8 even if the number of magazines 1 to be stored is increased. Furthermore, even if the strength of the transport platform 8 is increased, the load applied to the magazine 1 itself also increases, so the strength of the magazine 1 must also be increased. Furthermore, since a large number of magazines are already in circulation in the general market, the modification of the magazine 1 will be a major undertaking.

Furthermore, if the heights of the magazine storage sections 6 and 7 are increased, the height of the magazine storage device 5 increases, which also has the disadvantage of making it difficult to replace the magazine 1.

The purpose of this invention is to propose a magazine storage device that can increase the magazine storage capacity without increasing the strength of the magazine or the transport platform.

"Means for Solving Problems" In this invention, in a magazine storage device equipped with multiple rows of magazine storage sections for storing multiple stacked magazines, one empty row is provided in these multiple rows of magazine storage sections. The magazines stored in the magazine storage sections of other rows are sequentially conveyed to this empty row via the IC ejection port or the IC supply port, and by this transportation, the empty row section is filled and the magazines are ejected. This system is configured so that a row of magazine storage sections that have been used for storage is left empty, another magazine is stored in this empty row from another magazine storage section, and this process is repeated to sequentially move the position of one empty row. be.

According to the configuration of this invention, a plurality of rows of empty magazine storage sections storing empty magazines are provided, one empty row is prepared for the plural rows of empty magazine storage sections, and a magazine or magazine storing an IC is provided in this empty row. The IC is ejected and the empty magazine is fed and stored.

Once all the magazines have been ejected, a magazine is fed into the empty magazine storage section again from another magazine storage section. By repeating this process and sequentially moving the positions of the empty rows, all of the initially set empty magazines can be stored with ICs.
In addition, the IC supply section can eject all ICs from the magazine containing the initially set ICs.

Therefore, according to this invention, a large number of magazines can be stored in the magazine storage section without increasing the height of the magazine storage section. Therefore, it is not necessary to make the strength of the conveyance platform particularly strong. Furthermore, the storage capacity of the magazine storage section can be increased without increasing the strength of the magazine.

``Example'' Figure 1 shows an example of this invention. In FIG. 1, 5 indicates the entire magazine storage device. In this example, five rows of magazine storage sections 5A, 5B, 5C,
The case where 5D and 5E are provided is shown.

In this invention, one of the five magazine storage sections 5A to 5E is initially set to be empty. In the illustrated example, the magazine storage section 5A is initially set to the empty row, and the empty magazines 1 are stored in the magazine storage sections 5B to 5E in the other rows. In addition, IC ejection ports 4A to 4 are located below each magazine storage section 5B to 5E.
D is provided, and the plurality of IC discharge ports 4A to 4D are selectively opened and closed, and only good products, for example, are discharged from any one of them.

A common magazine conveyance table 8 is provided for the plurality of rows of magazine storage sections 5A to 5E. In this example, the magazine conveyance table 8 is divided into a lift section 8A and a slide section 8.
A case constructed by B is shown.

The lift section 8A moves only in the vertical direction and performs the operation of receiving one magazine from any one magazine storage section. Further, the slide portion 8B is formed to be shorter by one storage length in the arrangement direction of the magazine storage portions 5A to 5E, and is configured to be able to move laterally by one storage amount.

The lift section 8A rises and first lifts the magazine storage section 5B adjacent to the empty magazine storage section 5A.
It receives one magazine 1 from there, descends, and delivers it to the slide section 8B. At this time, the IC discharge port 4A is opened, and ICs determined to be good, for example, are discharged from the IC discharge port 4A. The lift part 8A is formed with a through hole through which the slide part 8B can pass, and when the lift part 8A is lowered, the slide part 8B is inserted into this through hole, and the lift part 8A moves below the slide part 8B. be able to. At this time, the magazine 1 is delivered to the slide section 8B,
At this position, when the magazine 1 facing the IC ejection port 4A and receiving the IC ejection becomes full with ICs 2, the slide part 8B moves laterally in the through hole formed in the lift part 8A, and the magazine 1 is moved into one The magazine 1 received from the magazine storage section 5B is moved by the pitch of the magazine storage section to the lower side of the empty magazine storage section 5A.
starts to rise again, receives the magazine 1 placed on the slide section 8B, ascends, and inserts this magazine into the empty magazine storage section 5A.

In this way, the empty magazine 1 is taken out from the magazine storage part 5B, and after the operation of receiving ICs ejected from the test device, it is transported to the empty magazine storage part 5A. When the magazine storage part 5A becomes full, At this time, the magazine storage section 5B becomes empty as shown in FIG.

When this state is reached, the IC ejection port 4B is then controlled to open, and supply of the magazine 1 from the storage section 5C is started, and the magazine 1 taken out from the magazine storage section 5C passes through the IC ejection port 4B and is stored in the magazine. Moved to section 5B. When the magazine storage section 5B becomes full with magazines 1, the magazine storage section 5C becomes empty as shown in FIG.

Next, the IC ejection port 4C is controlled to open, the empty magazine 1 is taken out from the magazine storage section 5D, and the IC is ejected from the IC ejection port 4C.
It is stored in C. By repeating this process, the magazine 1 stored in the magazine storage section 5D is moved to the magazine storage section 5C, and the magazine storage section 5D becomes empty.

Next, the IC ejection port 4D is controlled to open, and the empty magazine 1 is taken out from the magazine storage section 5E.
Moved to D.

"Modified Embodiment" FIG. 6 shows a modified embodiment of this invention. This example shows a case where a plurality of empty rows are provided for a plurality of magazine storage sections 5A to 5L. That is, in the initial state, 5A, 5D, 5G, and 5J are set to empty rows.

By providing multiple empty rows in this way, four magazines can be moved at once in this example, and ICs ejected from four different IC ejection ports 4A to 4D can be taken into the four magazines. I can do it.

Therefore, it is convenient for classifying good products into those with fast response speed, those with medium response speed, those with slow response speed, etc., for example.

In addition, although the magazine storage device installed at the IC ejection port of the test equipment was explained above,
This idea can also be applied to a magazine storage device provided on the IC supply side.

"Effect of the invention" As explained above, according to this invention, by simply providing one row of empty magazine storage sections among multiple magazine storage sections, all the magazines can be moved and ICs can be stored in the magazines. . As a result, in order to increase the number of magazines stored, there is no need to increase the height of the magazine storage sections 5A to 5E by increasing the number of magazine storage sections, so there is no need to make the magazine transport platform 8 particularly strong. Also, there is no need to increase the strength of the magazine itself. Further, since there is no need to increase the height of the magazine storage device 5, there is an advantage that magazine replacement work can be easily performed.
