However, the IC can be taken out even if the container 5B for the defective product is connected to the unloader unit 4A containing the non-defective product. Therefore, if such a connection mistake is made, the unloader will be unloaded. This causes a problem that the IC taken out from the parts 4A to 4C cannot be sent to a predetermined next process. This problem causes, for example, defective products to be mixed in the ICs to be shipped.

Therefore, the present invention relates to an unloading method for taking out a measured IC from an unloader section of an IC measuring auto-handler to an IC carrying tool, and I is used for dividing the measurement results.
It is an object of the present invention to provide a method for preventing the mistake of messing up the C carrier.

[0007]

In order to achieve the above object, the method of unloading an IC according to the present invention is such that the measured ICs of the IC measurement auto-handler are separately stored in the measurement result sections. A method for unloading an IC from an unloader section to an IC carrying tool that is distinguished according to the section, wherein the IC carrying tool is provided with a mark for identifying the section, and the unloader section is provided with a recognition for identifying the sign. Means is provided, and when the IC carrying tool is connected to the unloader section from which an IC is to be taken out, the marker of the IC carrying tool is identified by the recognition means of the unloader section, and the sign indicates the unloader section. The IC is delivered from the unloader unit to the IC transporting tool only when it matches the classification.

The mark is a through hole provided at a different position for each distinction of the IC carrying tool, and the recognizing means is an optical sensor utilizing light passing through the through hole, or It is preferable that the sign is a bar code and the recognition means is a bar code reader.

[0009]

The identification of the mark performed when the IC carrying tool is connected to the unloader section makes it possible to confirm whether or not the two connected are aligned on the section of the measurement result. However, only when the matching is confirmed, I
C Send the IC to the carrier.

Therefore, the unloading of the IC from the unloader section to the IC carrying tool is carried out by I during the division of the measurement results.
C. The mistake of mistakenly carrying the transport tool is prevented. The combination of the through hole and the optical sensor or the combination of the bar code and the bar code reader makes it possible to easily realize the above-mentioned mark identification by a usual existing technique.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first and second embodiments of the present invention will be described below with reference to the perspective views of FIGS. In all of these embodiments, the present invention is applied to the IC measurement auto handler described in FIG. 3, and the same reference numerals denote the same objects throughout the drawings.

In FIG. 1, in this first embodiment, the markers provided on the containers 5A to 5C serving as IC carrying tools are through holes 6, and the recognizing means provided on the unloader sections 4A to 4C is an optical sensor 7. .

The through hole 6 is a hole which is penetrated in the lateral direction in the vicinity of the ends of the containers 5A to 5C connected to the unloader portions 4A to 4C, and the positions of the containers 5A to 5C are different from each other. .

The optical sensor 7 has a structure in which the light receiving section detects the light flux from the light projecting section, and the light flux passes through the through hole 6 of the container 5A when the container 5A is connected in the unloader section 4A. In the unloader unit 4B, the light flux passes through the through hole 6 of the container 5B when the container 5B is connected, and in the unloader unit 4C, the light flux passes through the through hole 6 of the container 5C when the container 5C is connected. It is arranged as follows.

As a result, if a connection error such as connecting the container 5B to the unloader section 4A is made, the light receiving section will not detect the luminous flux, and therefore the unloader section 4A, 4B or 4C which is going to take out the IC. It is possible to confirm whether or not the containers 5A, 5B or 5C connected to the are aligned on the division of the measurement result.

And only when the matching is confirmed,
The stop by the stopper 4a is released and the IC is sent to the container. Therefore, the unloading of the ICs from the unloader units 4A to 4C into the containers 5A to 5C does not cause the mistake of mistaking the containers between the measurement result sections.

Further, in FIG. 2, this second embodiment is
The bar code 8 is used as a mark provided on the containers 5A to 5C as IC carrying tools, and the bar code reader 9 is used as a recognition means provided to the unloader units 4A to 4C.

The bar codes 8 are arranged at the same positions in the vicinity of the ends connected to the unloader sections 4A to 4C of the containers 5A to 5C, respectively, and the information is different between the containers 5A to 5C. .

The bar code reader 9 includes an unloader section 4A-
The information of the barcode 8 of the containers 5A to 5C connected to the 4C is read, and is provided in each of the unloader units 4A to 4C.

As a result, the container 5A, which is connected to the unloader section 4A, 4B or 4C from which the IC is to be taken out,
It is possible to confirm whether 5B or 5C is consistent with the classification of the measurement result.

And only when the matching is confirmed,
The stop by the stopper 4a is released and the IC is sent to the container. Therefore, as in the case of the first embodiment, the unloading of the ICs from the unloader units 4A to 4C into the containers 5A to 5C does not cause the mistake of confusing the containers between the measurement result sections.

In the above embodiment, the IC carrying tool is a tube-shaped container, but the IC carrying tool may be a tray in the same manner as in the embodiment.
