In particular, the present invention relates to a container for semi-finished or finished products which enables setting to an automatic machine for processing.

[Conventional technology]

Generally, when processing a product in a factory, when a semi-finished product is transported from one process to another process or when a product is transported from one factory to a factory, a container for storing a plurality of these products is provided. It goes in the state that it was stored in. Conventionally, as this type of container, a container in which a plurality of product storage cavities are formed has been proposed, and each product is stored in the storage cavities, and a lid is placed over the containers.

Then, at the destination, inspection and cleaning are performed in units of this storage container, and further, setting to an automatic machine for processing is performed.
We are working on the next process.

[Problems to be Solved by the Invention] In a conventional container, a plurality of storage cavities are formed in a plate-shaped or shallow dish-shaped container, the cavity product is inserted, and the container is covered with a lid. However, if there is a margin (backlash) in the product in each cavity, the product will vibrate in the cavity due to the vibration during transportation, and this vibration causes abrasion between the product and the inner wall of the cavity, causing the abrasion powder to become foreign matter. Adhere to the parts. Therefore, in the next step, cleaning of the product becomes essential, and the processing efficiency of the next step is reduced.

Further, in the conventional storage container, the storage direction of the product in the cavity is specified, but the storage container itself has no directionality. Therefore, when the storage container is loaded into the automatic machine as it is for processing, a worker may make a mistake in the loading direction and may erroneously process the product.

Furthermore, the conventional storage container is not configured to take into consideration the handling of the product, especially in an automatic machine, and the handling of the product or the re-storing operation after processing may not be automated in some cases.

An object of the present invention is to provide a storage container capable of preventing foreign matter from adhering to a product and eliminating an error in loading into an automatic machine.

[Means for solving problems]

The storage container of the present invention has an array of a plurality of storage cavities for respectively storing products, each of the cavities is provided with a guide portion for storing the product at a predetermined position in a predetermined posture, and has an allowance portion for handling. In addition to the provision, an index portion that indicates the direction of the container is formed in a part of the container.

The guide portion is formed by a concave groove or a tapered portion according to the product size, and a finger for handling can be inserted into the allowance portion.

The index portion has one corner formed in a tapered shape.

[Action]

In this storage container, the guide portion allows the product to be stored in a predetermined position in the cavity, and the handling from the container is facilitated, and the processing can be automated by setting the container as it is on an automatic machine. In this case, the index portion provided on the container can prevent an error in setting the automatic machine.

Also, by holding the product in the cavity in a predetermined posture stably by the action of the guide portion, it is possible to prevent the generation of abrasion powder due to the vibration during transportation, prevent the product from being contaminated, and the cleaning process is unnecessary. Improvement of processing efficiency can be achieved.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a plan view of the storage container of the present invention, and FIG. 2 is its AA.
FIG. 3 is a sectional view taken along the line BB, and here, in the case where a substantially rectangular plate-shaped glass cap that constitutes a part of the package of the semiconductor device is used as a product, a container for accommodating the same is used. The example to which the present invention is applied is shown.

The storage container 1 is made of resin or the like and is formed into a substantially square plate shape, and a plurality of storage cavities 2 are formed on the upper surface of the storage container 1 in an array in the vertical and horizontal directions. Here, each of the cavities 2 is formed in series in the vertical direction, and is formed in a plurality of rows in the horizontal direction at predetermined size intervals.

Each of the storage cavities 2 is formed with a concave groove 3 having a triangular planar shape facing each other on both sides as a guide portion, and a glass cap G can be inserted between the concave grooves 3 forming a pair. A tapered portion 4 having a groove width gradually reduced is formed on the lower side of the concave groove 3, and the inserted glass cap G is guided by the tapered portion 4 to be naturally positioned at the central position of the concave groove 3. I am trying to keep it. In this case, the depth of the groove 3 is the glass cap G.
It is slightly smaller than the size.

Further, a bottom groove 5 extending in the vertical direction is provided on the bottom surface of the central portion of each cavity 2, and a through hole 6 is opened in the bottom groove 5 corresponding to each storage cavity 2.

Further, the storage container 1 has four sides which are bent downward to form a peripheral wall 7, and a flange 8 is provided on the lower side thereof. The three corners of the four corners of the peripheral wall 7 are formed at right angles, but the tapered index portion 9 is formed at one corner.

Therefore, according to this storage container, each cavity 2
Insert the glass cap G into the glass cap G
Both end edges of the glass cap G are guided by the recessed groove 3 and the tapered portion 4 below the recessed groove 3, and the glass cap G can be stored in the center position of the cavity 2 with high precision.

Then, as shown in FIG.
Put the whole in a flexible bag 10 and put this bag 10
By pulling a vacuum through the opening of the
Is brought into close contact with the upper edge of the glass cap G, and this close contact force holds the glass cap G in the storage cavity 2. Therefore, the glass cap G is not vibrated in the cavity 2 during the transportation, and the contamination due to the abrasion powder can be prevented.

When setting the storage container 1 on the automatic machine for the next process, the operator checks the index portion 9 of the storage container 1 and loads the storage container in the preset direction. G can be supplied to the automatic machine in a predetermined posture.

In this case, if a part of the pedestal P of the automatic machine is configured asymmetrically as shown by the diagonal lines in FIG. 2, it is possible to confirm the quality of setting by the fitting state with the pedestal P. .

When handling the glass cap G from the storage container 1, as shown in FIG. 5, the lower end portion of the handling finger F having a substantially U shape is inserted into the bottom groove 5, so that the glass cap G can be easily handled. It can be clamped in the up and down direction and can be handled easily. In this case, in the cavity 2 at the end in the vertical direction, the bottom groove 5 is projected from the end of the cavity 2, so that the glass cap G stored in the cavity 2 at the end can be easily handled. .

In addition, when the clean air is jetted to the storage container 1 when it is set in the automatic machine, the clean air is cavities 2.
It is also possible to keep the environment of the glass cap G in a clean state and prevent foreign matters from adhering to the glass cap G by flowing through the through holes 6.

Here, the shape of the cavity is shown in FIG.
Can also be configured as.

That is, the depth of the plurality of storage cavities 2A formed is made larger than the size of the glass cap G so that the stored glass caps G can be stored while being completely embedded in the cavities 2A. In this case, Cavity 2A
A projection 5a for receiving the lower end of the glass cap G is formed on the bottom surface of the bottom groove 5A, and a handling finger F can be inserted by ensuring a gap between the glass cap G and the bottom surface.

In this storage container 1A, as shown in FIG. 7, the inside of the bag 10 is evacuated by putting it in the bag 10 without covering the upper lid, and a part of the bag 10 is brought into close contact with the upper edge of the glass cap G and the upper surface of the container. By pressing this, the glass cap G can be stably supported in the cavity 2A. Therefore, the upper lid is not required, the number of parts can be reduced, and the storage containers can be stacked on each other, so that the cost and the storage space can be reduced.

Here, in the above-mentioned embodiment, the example of the glass cap is shown as the storage product, but it can be similarly applied to the semiconductor device structure just before completion or the container for storing the completed semiconductor device and other electronic parts.

〔The invention's effect〕
