Abstract

PROBLEM TO BE SOLVED: To enable numerous works received in a cavity to be positioned at a time to facilitate positioning by sucking the works through a suction hole provided on an inner side face of the cavity, moving the works horizontally and positioning them in the cavity. SOLUTION: A suction path 12 corresponding to a suction hole 3 of a cavity 2 is provided on a mount 11 where the storage tool 1 is mounted. A work 5 is sucked through the suction hole 3 of the cavity 2 and the suction path 12 of the mount 11 by a vacuum exhausting device, whereby the work 5 is brought to an upper left corner where the suction hole 3 is provided in the cavity 2. At this time a side face 5a of the work 5 is in tight contact with an inner side face 2b of the cavity 2 due to frictional force occurring between the work 5 and the inner side face 2a of the cavity 2, so that the work 5 is horizontally fixed. Thus, since the storage tool 1 need not be tilted or the work 5 need not be touched, the positioned work may not shift in position.

It is necessary to arrange them at the same position inside the cavity 21, that is, to perform so-called positioning. This positioning is realized, for example, by bringing the side surface of the work 23 into contact with the inner side surface of the cavity 21 and closely contacting it.

[0005] In the conventional storage device, in the suction fixing performed through the suction hole 22 in the cavity 21, the work 23 is suction-fixed toward the bottom surface 21 a of the cavity 21, that is, in the vertical direction of the storage device 20. However, it is difficult to perform alignment and positioning in the horizontal direction in the cavity 21, and as shown in FIG. 5, the position of the work 23 in each cavity 21 may be uneven. . And such a work 23
In order to eliminate the irregularity and to position the work 23, the work 23 is aligned by separate mechanical equipment or the storage tool is tilted by hand to offset the work 23 before suction by the vacuum exhaust device is performed. Needed. However, in such a positioning operation, complicated mechanical equipment may be required, and the operation time is prolonged, resulting in poor efficiency. Further, after the operation, the work 23 may be displaced.

Accordingly, an object of the present invention is to provide a storage tool which can easily position a work stored in a cavity.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a storage device according to an embodiment of the present invention will be described with reference to FIGS.

In each of the drawings, reference numeral 1 denotes a storage tool, and a plurality of substrates 10a, 10b, and 10c are laminated and integrated.
It is a plate-shaped member having a front surface 1a and a back surface 1b. Also,
A plurality of cavities 2 having a rectangular bottom surface 2a and four inner side surfaces 2b are provided on the front surface 1a of the storage device 1. Further, a suction hole 3 is formed in the inner side surface 2 b of the cavity 2. Before the substrates 10a to 10c constituting the storage device 1 are stacked, the suction holes 3
c, formed by punching the cavity 2 and a portion continuous with the cavity 2, and the opening of the suction hole 3 is bent at a right angle across the two inner side surfaces 2 b of the cavity 2. And the bottom 2 of the cavity 2
a. The workpieces 5 are individually stored in the cavities 2 thus formed.

Next, a method of positioning and fixing the work 5 stored in the cavity 2 of the storage tool 1 will be described with reference to FIGS.
This will be described with reference to FIG.

First, the storage device 1 is mounted on the mounting table 11. The mounting table 11 is provided with a suction path 12 corresponding to the suction hole 3 of the cavity 2. Then, the work 5 is sucked by the vacuum exhaust device (not shown) through the suction hole 3 of the cavity 2 and the suction path 12 of the mounting table 11, and as shown in FIG. Inside 2, the suction hole 3 is drawn to the upper left corner where the suction hole 3 is provided. At this time, the frictional force generated between the work 5 and the inner surface 2a of the cavity 2 causes the side surface 5a of the work 5 to come into close contact with the inner surface 2b of the cavity 2, and the work 5
Are fixed horizontally in the drawing. Thus, the workpiece 5 is positioned by the suction using the suction holes 3. Here, for example, the area of the suction hole is 0.7 square mm,
When the suction pressure is -200 mHg and the distance between the work 5 and the inner surface of the cavity 2 is 0.5 mm, the coefficient of friction between the storage tool 1 and the work 5 is about 0.3,
If the weight is 0.2 gf, it is possible to position hundreds of workpieces 5 stored in the storage tool 1 in 1 to 2 seconds.

By the suction through the suction holes 3 as described above,
The work 5 moves in the horizontal direction and is fixed, and at the same time, the work 5 is fixed in the vertical direction, that is, the close contact of the work 5 with the bottom surface 2a of the cavity 2 is ensured. This is because the opening of the suction hole 3 is formed in contact with the bottom surface 2a of the cavity 2, and the work 5 moves horizontally without floating from the bottom surface 2a of the cavity 2.

As described above, in the storage device 1, the work 5 is inserted through the suction hole 3 provided in the inner surface 2 b of the cavity 2.
By sucking, the work 5 housed in the cavity 2 is moved in the horizontal direction, and positioning is performed in the cavity 2, so that a complicated facility is not required for the positioning work, and a large number of works 5 can be collected at once in a short time. The work 5 can be positioned, and the work 5 can be easily positioned. Also, during and after the positioning operation, there is no need to tilt the storage device 1 or touch the work 5, so that the work 5 does not shift.

Next, in this embodiment, the case where the suction hole is provided only on the inner side surface of the cavity has been described.
For example, as shown in FIG. 5, a suction hole may be provided on the bottom surface of the cavity. In FIG. 5, the same or corresponding parts as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

In this case, before the substrates 10a to 10c are stacked, the suction holes 4 in the bottom surface 2a of the cavity 2
A portion corresponding to the bottom surface 2a of the cavity 2 is formed by drilling. The mounting table 11 has the suction holes 4.
Is formed. Then, by sucking the work 5 through the suction hole 4, the work 5 is drawn to the bottom surface 2 a of the cavity 2, so that the work 5 is more firmly fixed to the bottom surface 2 a of the cavity 2. Here, for example, when the weight of the work 5 is 0.2
When gf, the radius of the suction hole 4 is 2.5 mm, and the suction pressure is-
If it is 100 mHg, several hundred works 5 stored in the storage tool 1 can be fixed in 1 to 2 seconds with a force of 6 gf or more.

In this embodiment, the work is positioned and fixed in the cavity at the upper left of the drawing, but by changing the position of the suction hole in the cavity,
The positioning direction of the work can be set arbitrarily.

[0019]

According to the storage tool of the present invention, the work is moved in the horizontal direction and positioned in the cavity by sucking the work through the suction hole provided on the inner surface of the cavity. No complicated equipment is required for the positioning work, and a large number of works can be positioned at once in a short time, so that the positioning work becomes easy. Moreover, during and after the positioning work, there is no need to tilt the storage device or touch the work, so that the positioned work does not shift.
