Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage tray for storing a plurality of electronic components.

[0002]

[Prior Art]

 In precision electrical products such as OA equipment and AV equipment, semiconductors called "industrial rice" instead of iron, and so-called electronic components such as modules that incorporate these semiconductors into substrates are semi-finished in the manufacturing process. Sufficient handling is required to prevent damage during storage, transportation, and shipment of finished products.

An electronic component storage tray made of a synthetic resin material (so-called plastic) by a vacuum molding method has been generally used for storage and transportation of the electronic components, but the electronic component storage tray is simply stored inside. Only the storage recess corresponding to the shape of the electronic component is provided, and when a large number of empty trays are stored and transported, there is an advantage that the occupied volume can be reduced by stacking the trays. It was not suitable for storing and transporting the above-mentioned trays with parts stored in the stack up and down.

That is, in the conventional electronic component storage tray, when the electronic components are stacked up and down in a state of being stored, the bottom of the storage recess for storing the electronic components of the upper tray corresponds to the storage of the lower tray. There is a high possibility that the electronic component in the recess is brought into contact with the electronic component and a load is applied to the electronic component below, resulting in damage to the electronic component.

Therefore, in the electronic component storage tray, in order to avoid a load on the electronic components due to stacking, the electronic components are not closely stacked vertically (the recesses do not enter each other), and The problem of the load can be avoided by completely storing the inside of the recess without exposing it.

[0006]

[Problems to be solved by the device]

 However, even if the problem of load is avoided, the above trays cannot be stacked when storing and transporting empty trays, resulting in a bulky and occupying volume which reduces storage and transport efficiency.

That is, in the conventional electronic component storage tray, when a large number of the electronic components are stored and stored or transported, the trays can be stacked in multiple layers vertically without damaging the electronic components. When storing and transporting empty trays, there are no electronic component storage trays that meet the two requirements at the same time that the occupied volume can be reduced and efficiency can be improved by stacking multiple trays on top of each other. Had an antinomy.

The present invention has been made in view of the above circumstances, and has a structure in which the electronic components are not directly loaded by being stacked when the trays storing the electronic components are vertically stacked and stored or transported. In addition, when storing a large number of empty trays, it is possible to provide an electronic component storage tray that can be densely stacked to reduce the occupied volume.

[0009]

[Means for Solving the Problems]

 According to the present invention, a plurality of storage recesses that are symmetrical in the front-rear, left-right and left-direction in which electronic components are mounted and stored on one main surface of a substantially plate-shaped tray are arranged symmetrically around a perpendicular line passing through the center of the main surface of the tray. In addition, the above object is achieved by providing an electronic component storage tray characterized in that uneven portions are arranged asymmetrically around the perpendicular line at a plurality of locations on the edges of the tray that face each other. is there.

[0010]

[Action]

 The electronic component storage tray according to the present invention has a plurality of concave and convex portions which are asymmetrical with respect to a perpendicular line passing through the center of the main surface of the tray, and the tray containing the electronic components is moved upward and downward. When the trays are stacked on top of each other, the back surface of the bottom surface of the uneven portion of the upper tray comes into contact with the asymmetric surface of the lower tray, so that the upper and lower trays do not overlap with each other. There is no risk of damaging the electronic component stored in the recess.

When a large number of empty trays are to be stored or transported, if the electronic components are stored and vertically stacked, and then the electronic components are stacked upside down by 180 degrees, the upper and lower trays are stacked. The concave and convex portions arranged at the edges can be aligned with each other to be densely stacked.

In the above-mentioned use, the storage recesses for storing the electronic components of the tray have a front-rear and left-right symmetric shape, and a plurality of storage recesses are arranged symmetrically with respect to a vertical line passing through the center of the main surface of the tray. Even if it is changed, the upper and lower concave portions always correspond in position and overlap with each other.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of an electronic component storage tray 1 used in this embodiment and a perspective view showing a state in which an upper tray is superposed on a lower tray 1 in which an electronic component 2 is stored.

The synthetic resin material used for the tray 1 is so-called plastic, which is easily and inexpensively integrally molded and is used in various fields as a simple container. It is possible to easily take measures against static electricity by mixing an appropriate amount of carbon fine powder into the material.

The synthetic resin is used as a material to be formed into a substantially plate shape by a vacuum forming method. The tray 1 is provided with a storage recess 3 which is symmetrical in the front-rear direction and the left-right direction in which the electronic component 2 is stored, in conformity with the shape of the electronic component 2, and several positions of the edges 4 to 7 of the tray which face each other. In this structure, the uneven portion 8 is asymmetrically arranged around a vertical line passing through the center of the main surface of the tray.

The overall size of the tray may be of a size that is sufficiently rigid to withstand conveyance and that can be easily handled by one person. A square shape with one side of about 15 cm to 80 cm is suitable.

FIG. 2 is a perspective view showing a state where the empty trays 1 are stacked in two stages. At this time, the edge portions 4 to 7 of the tray 1 facing each other and the side surface portions 9 of the asymmetrical uneven portions 8 of the edge portions are all appropriately inclined outward with respect to the vertical direction, and the tray storage recesses are formed. All of the side faces 10 of 3 have a structure in which the inside of the recess is appropriately inclined with respect to the vertical. Therefore, the upper and lower trays 1 overlap with each other so that the corresponding surfaces come into contact with each other, and a large number of empty trays 1 can be densely stacked vertically without increasing the occupied volume. FIG. 3 is a perspective view showing a state in which the trays 1 are stacked in several stages as described above.

On the other hand, when the trays 1 containing the electronic components 2 are stacked in the same manner as in the case of the empty tray, the bottom surface of the storage recess 3 of the upper tray is located inside the storage recess 3 of the lower tray. In this case, the upper and lower trays should be stacked with the front, back, left and right directions reversed by 180 degrees, as they will interfere with the electronic components stored in the tray and apply an extra load.

That is, according to the above-mentioned stacking method, the uneven portions 8 asymmetrically arranged at the edges do not correspond in position in the upper and lower trays, and the back surface of the bottom surface of the upper uneven portion 8 becomes the upper surface 11 of the lower tray. The structure is such that it abuts and holds the upper tray. Therefore, the storage recesses 3 of the tray in which the electronic components 2 are stored do not closely overlap with each other, and no load is applied to the electronic components 2.

Although the electronic component 2 stored in the electronic component storage tray 1 shown in this embodiment is a quadrangular electronic circuit, the type of the electronic component 2 is not limited to this. For example, it may be a semiconductor IC element or an electronic circuit in which an electronic element is mounted on a circular substrate. The above case can be dealt with by matching the shape and size of the storage recess 3 with the electronic component.

Further, although the outer shape of the electronic component storage tray is a quadrangle in this embodiment, the present invention is not limited to this, and passes through the center of the main surface of the tray, for example, in a circular shape. Other shapes may be used as long as they are 180 degrees symmetrical with respect to the vertical line.

[0023]

(1) It has an excellent effect that storage and transportation of electronic parts can be performed safely and efficiently.

(2) It has an excellent effect that a large number of empty trays when not in use can be efficiently stored and transported with a minimum occupied volume.
