JPS6052404A - Holding mechanism for magazine charged with ic - Google Patents

Abstract

PURPOSE:To avoid fear of breakage of IC in a magazine due to a shock of falling down thereof and to increase holding efficiency by receiving magazines charged with IC in such a manner as to be gradually pushed up from the lowermost of a holding position. CONSTITUTION:In an apparatus for separating integrated circuits tested by a tester according to the test result and accumulating the integrated circuits put in magazines 3 in a plurality of holding lanes or charged magazine holders 2 disposed in parallel to an empty magazine holder 1, there is provided a guide extending along the lower end openings of the empty magazine holder 1 and the holding lanes 2. The apparatus further has a conveyor system 6 movable along the guide and provided with a conveyor arm 5 movable up and down. There is provided under each lower end opening of the holder 1 and the holding lanes 2 a openable stopper 4 adapted for preventing falling down of the magazines 3 vertically piled up in plural layers.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is directed to an ejection section (in which tested ICs (semiconductor integrated circuit devices) are classified according to test results and installed in multiple lanes).
A storage mechanism for the IC-loaded magazine of the IC handler that loads the IC-loaded magazine into the magazine of the IC handler (unloader) and efficiently stacks and stores the IC-loaded magazine in a predetermined magazine storage location without damaging the IC loaded in the magazine. Regarding.

[Background of the invention]

It is widely practiced to have a testing machine automatically test °ζIc sequentially using an IC handler. The tested ICs are classified into multiple types according to the energization and test results, and are sent out from the discharge section installed in multiple lanes and transferred into the magazine.The magazines loaded with these ICs are sequentially loaded into the magazine. It is designed to be stored in the storage area.

Conventionally, the storage of a magazine loaded with ICs was done by ejecting the magazine.
-! A method was used in which the vehicle was dropped into a storage area located vertically downwards just below the shoulders, or a method in which the vehicle was stored horizontally in one direction.

However, these conventional methods have various problems.

In the case of the drop type, the Ic inside the magazine may be damaged by the fffj impact when the fti hits the bottom of the storage area after being dropped or the 1c loaded magazine that has already fallen. In particular, in the case of Ceraminoku Paso Gauge ICs, the incidence of damage is high.

Mano 1: In the case of the horizontal feeding method, if multiple cages are provided, the transportation means will be complicated and a large space will be required.C
There are many problems such as

[Purpose of the invention]

It is an object of the present invention to provide a magazine loaded with ICs that does not have the above-mentioned problems, that is, damage to the ICs loaded in the magazine, and that can easily handle cases where multiple lanes are installed. The purpose is to provide a storage mechanism.

[Summary of the invention]

In order to achieve the above object, the present invention takes out empty magazines from the bottom of a storage area stacked in multiple groups, transports them to a position where tested ICs are ejected, and places them in a predetermined posture. Empty-7 magazine 1 General feeding means and the magazine loaded with IC that has been ejected in this position and attitude. At the same time, stack the IC-equipped macacines in multiple stages, push the soil into the lowest stage of the stacked rows, and at the same time move the empty macacines to the position where the tested samples 10 are discharged, together with the empty macacine transport stage f. 7, transport and place the IC-loaded Macanon, and set up the lower tier of the stacking power.Because we adopted the push-up horn method instead of the dropping method, it was difficult to prevent the IC from being hit by the U when it fell. This can prevent damage to the IC, and even when the 4+ output section has multiple lanes, the magazines can be stacked vertically in multiple tiers, reducing the area. This is an economical storage method.

[Embodiments of the invention]

Figure 1 shows the implementation of the present invention, IO at high temperature and low! FIG. 2 is a perspective view showing the entire system of a high-temperature handler that can be tested in the XA state. 1 is the empty magazine storage area, 2 is the storage lane (IC
Loaded magazine storage section), 8 is the classification section, 9 is a constant temperature bath,
10 is a constant temperature sliding inlet L1. 11 is a constant temperature chamber outlet. In reality, in addition to these, there is also an IC supply section of an IC handler that supplies ICs from the entrance 10 to the test position, and a test machine that measures the characteristics of the IC inserted into the socket provided at the test position by the IC handler. It is being The ICs whose characteristics have been measured by the test machine at the test position come out from exit 11, move laterally, and are then transported to a predetermined storage lane position according to the test results and classified by the sorting section. , will be stored in a predetermined storage lane. Other than the empty magazine storage section 1 and the storage lane 2, the members related to the present invention are hidden below and cannot be seen.

2 to 6 are diagrams illustrating the operating sequence of the embodiment of the present invention. In these figures, 1 is an empty magazine storage area, 2 is a storage lane, 3 is a magazine, and 4 is a magazine stopper (signal) to prevent magazines stacked vertically in multiple tiers from falling down. 5 is a transport arm, 6 is a transport system, and 7 is an IC.

Figure 2 shows a state in which the magazine stopper 4 at the bottom of the empty magazine storage section 1 is opened and only one empty magazine 3 is loaded onto the general transport arm 5. Lower the arm 5 as shown by the arrow and move it to the left at the same time, and the Ic7 is finished loading into the magazine 3 which is connected to the IC ejection part of the IC handler at the bottom of the storage lane 2 and is in the ζIC receiving position. He is trying to bring the one-leg feed arm 5 to the bottom of the storage lane 2, which is second from the left in the figure.

FIG. 3 shows a state in which the transfer arm 5 has finished moving below the second storage lane 2 from the left and is about to turn upward.

Figure 4 shows that the transport arm 5 has been raised, the magazine collar 4 has opened to the left and right, and the empty magazines have been stacked in two tiers inside this storage lane (second from the left) to the IC-loaded magazines. This shows that the entire row is about to be pushed upwards.

Figure 5 shows that the empty magazine is pushed up to the bottom of the second storage lane from the left, and in this state the magazine stopper bar 4 has finished moving from left and right to the center - the ζ magazine is in a state where it does not fall downward and is transported. This shows a state in which the arm 5 has begun to move downward. This figure shows an example where there are three rows of storage lanes for tested ICs, but the number of ICs that are ejected into each lane is not uniform and is generally close to the center of the standard. The majority are classified into the lanes having the characteristics (in the case of this figure, those classified into the center, ie, the second lane from the left).

Figure 6 shows that after the supply of empty magazines to the second storage lane from the left has been completed, the first general transport arm 5 has moved to the empty magazine storage area.
[Effects of the Invention] As explained above, according to the present invention, the magazines loaded with ICs are stored in the storage position 11KI sequentially from the bottom f) 15 to 1-
Since the car is pushed down, the IC loaded in the magazine will not be damaged by the impact of falling, and the IC loaded magazine can be stored directly above the IC ejection part of the IC handler. Since the magazines are stacked vertically in multiple stages, it is economical in terms of space.
