Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container for storing products such as semiconductor devices, and in particular, a container for storing semi-finished or completed products that can be transferred to an automatic processing machine or the like. Regarding containers.

[Conventional technology]

Generally, when processing products in a factory, there is a need for transporting semi-finished products from one process to another, or when -
When transporting products from one factory to another, a plurality of these products are stored in storage containers. Conventionally, as this type of container, a container having a plurality of product storage cavities has been proposed, in which a product is placed in each storage cavity and a lid is placed over the product.

At the destination, each storage container is inspected and cleaned.
Furthermore, they set up automatic machines for processing and carry out the next process.

[Problem that the invention seeks to solve]

In conventional storage containers, multiple storage cavities are formed in a plate-shaped or shallow dish-shaped container, and the product is inserted into the cavities and then covered with a lid. If there is play, the product will vibrate within the cavity due to vibrations during transportation, and this vibration will cause wear between the product and the inner wall of the cavity, and wear particles will become foreign matter and adhere to the parts. Therefore, cleaning of the product is required in the next step, and processing efficiency in the next step is reduced.

Further, although the conventional storage container specifies the storage direction of the product within the cavity, the storage container itself has no directionality. For this reason, when a storage container is directly loaded into an automatic machine and processed, a problem may arise, such as an operator loading the container in the wrong direction and erroneously processing the product.

Further, conventional storage containers are not designed with special consideration given to handling of products in automatic machines, and it may not be possible to automate handling of products or re-storage after processing.

SUMMARY OF THE INVENTION An object of the present invention is to provide a storage container that can prevent foreign matter from adhering to products and eliminate errors in loading products into automatic machines.

[Means for solving problems]

The storage container of the present invention has a plurality of storage cavities arranged in an array for storing products, each cavity having a guide portion for storing the product in a predetermined position and a predetermined attitude, and an allowance for handling. In addition, a part of the container is provided with an index portion indicating the direction of the container.

The guide portion is configured with a concave groove or a tapered portion that matches the product dimensions, and is configured such that handling fingers can enter into the margin.

The index portion is formed into a tapered shape at one corner of the container.

[Effect]

In this storage container, the product can be stored in a predetermined position in the cavity by the guide portion, and handling from the container is easy, and furthermore, the container can be directly sewn into an automatic machine to automate processing.

In this case, the index section provided on the container can prevent errors in setting the container in the automatic machine.

In addition, by stably holding the product in a predetermined position within the cavity through the action of the guide part, it is possible to prevent the generation of abrasion powder due to vibration during transportation, prevent product contamination, and eliminate the need for a cleaning process. Improved 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 an AA view thereof.

An example to which the present invention is applied is shown.

This storage container 1 is formed entirely into a substantially square plate shape using resin or the like, and has a plurality of storage cavities 2 on its upper surface.
are arranged vertically and horizontally on a plane. Here, the cavities 2 are formed in series in the vertical direction, and are formed in a plurality of rows in the horizontal direction at predetermined intervals.

Each storage cavity 2 has concave grooves 3 having a triangular planar shape facing each other as guide portions on both sides, and these concave grooves 3 form a pair.
A glass cap G can be inserted in between. A tapered part 4 whose groove width is gradually reduced is formed on the lower side of this groove 3, and the inserted glass cap G is guided by this tapered part 4 and is naturally placed in the center position of the groove 3. I'm trying to keep it.

In this case, the depth of the groove 3 is made somewhat smaller than the dimension of the glass cap G.

Further, a bottom groove 5 that is continuous in the vertical direction is provided on the bottom surface of the central part of each cavity 2, and the bottom groove 5 is provided with a bottom groove 5 that connects each storage cavity 2.
Through hole 6 has been opened in response to this.

Moreover, the storage container 1 has four sides bent downward and the surrounding wall 7
, and a flange 8 is provided on its lower side. Three of the four corners of the surrounding wall 7 are formed at right angles, but a tapered index portion 9 is formed at the minus corner.

Therefore, according to this storage container, when the glass cap G is inserted into each cavity 2, both end edges of the glass cap G are guided by the groove 3 and the tapered part 4 on the lower side, and the glass cap G is inserted into the cavity 2. It can be stored with high precision in the central position.

Then, as shown in FIG.
By drawing a vacuum through the opening of the bag 10, the top cover C of the bag 10 is brought into close contact with the upper edge of the glass cap G, and this contact force holds the glass cap G within the storage cavity 2. Therefore, the glass cap G is not vibrated within the cavity 2 during transportation, and contamination by abrasion powder can be prevented.

When setting this storage container 1 into the automatic processing machine for the next process, the operator checks the index section 9 of the storage container 1, loads the storage container in the preset direction, and then the glass cap G can be supplied to an automatic machine in a predetermined posture.

In this case, as shown by diagonal lines in Fig. 2, if the automatic machine's holder is constructed with a part of the stand P asymmetrical, it is possible to check whether the setting is correct or not based on the fitting state of the holder with the stand P. You can also do it.

When handling the glass cap G from the storage container 1, as shown in FIG. Can be easily held vertically,
Easy to handle. In this case, in the cavity 2 at the end in the longitudinal direction, the bottom groove 5 is made to protrude from the end of the cavity 2, so that it is possible to easily handle the glass cap G stored in the cavity 2 at the end. can.

Note that when set up in an automatic machine, when clean air is injected into the storage container 1, the clean air flows through the cavity 2 and the through hole 6, keeping the environment of the glass cap G clean and preventing the adhesion of foreign matter. It can also be prevented.

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

That is, the depth of the plurality of storage cavities 2A is made larger than the dimensions of the glass caps G, so that the stored glass caps G can be stored in a state completely buried in the cavities 2A. In this case, a protrusion 5a is formed on the bottom of the bottom groove 5A of the cavity 2A to receive the lower end of the glass cap G, and a gap is secured between the glass cap G and the bottom to allow insertion of the handling finger F. There is.
