Description

  The present invention relates to a tray that stores electronic devices during an assembly process or storage, and more particularly to an electronic device storage tray that includes a wireless tag that can read and write information on stored electronic devices and that can be stacked.

  Conventionally, in an assembly process and a storage process of an electronic device such as a liquid crystal television, a tray is used for temporarily storing unfinished modules (hereinafter simply referred to as “modules”) of these electronic devices. Such a tray is provided with various types of tags and labels indicating the types of modules stored in the tray and the in-process status.

Patent Document 1 discloses such a tag that uses an RFID that can read and write information wirelessly. In Patent Document 1, a label using an RFID is attached to a tray, and information on the module stored in the RFID is read and written to manage the type of module stored in the tray and the status of the work in progress. Yes.
Special table 2003-519608 gazette

  By the way, when storing such trays in the process, a large space is required unless these trays are stacked and stored. In particular, in the case of a module of a large electronic device such as a large liquid crystal television, a very large space is required.

  For this reason, the conventional tray is formed in a stackable structure as shown in FIG.

  FIG. 6A is an external perspective view showing a schematic configuration of a conventional tray, and FIG. 6B is a perspective view showing a stacked state thereof.

The tray 1 is formed, for example, in a substantially rectangular parallelepiped shape from a high-strength foam material or the like, and includes a storage recess 2 in which a module is disposed. A wireless tag 10 having an RFID is disposed on the tray 1 by being attached or embedded at a predetermined position.
Moreover, the upper fitting part 3 is provided by providing a predetermined unevenness on each side part on the upper surface side of the substantially rectangular parallelepiped shape, and the upper fitting part 3 is fitted on each side part on the lower surface side of the substantially rectangular parallelepiped shape. The lower fitting part 4 is provided by providing unevenness in shape.

  Then, by fitting the upper fitting portion 3 and the lower fitting portion 4 of the plurality of trays 1 as shown in FIG. 6B, these trays 1 are stably stacked.

  In such a conventional tray, the opposing side portions of the upper fitting portion 3 are formed symmetrically so as to facilitate stacking. For example, as shown in FIG. 6 (a), the side portions 3a and 3b of the upper fitting portion 3 are symmetrical with respect to the central axis in the long side direction of the tray 1, and the side portions 3c and 3d are the centers. The shape is perpendicular to the axis and symmetrical with respect to the center of the tray 1. For this reason, the stacking direction of the trays is not constant, and there is a problem that the positions of the wireless tags 10 do not coincide with each other as shown in FIG. Here, the power of the antenna 50 is adjusted so that the antenna 50 transmits radio waves only to the wireless tag of the tray placed in the process of monitoring itself, and does not transmit radio waves in a wider range than necessary. Further, the wireless tag 10 used in a large amount in such a tray or the like does not have a power source and has a short radio wave transmission reach range. For example, a large-sized liquid crystal television or plasma television having a screen size of 30 inches or more is used. In a tray that stores large electronic devices such as John, the length of the side (side wall) of the tray may be longer than the radio wave transmission transmission range. For this reason, the radio tag 10 of the tray 1 that is not stacked in the normal direction cannot receive radio waves from the antenna 50, or even if the radio tag 10 receives radio waves from the antenna 50, the radio waves (information) transmitted are Do not reach 50 reliably. As a result, all of the wireless tags 10 cannot receive radio waves from the antenna 50 arranged in a single direction. As a result, information on the module 100 stored for the tray 1 (the second tray in FIG. 7) where the position of the wireless tag 10 is not a regular position cannot be obtained, and information on the module 100 is updated. I can't.

  An object of the present invention is to provide an electronic device storage tray having a shape in which all wireless tags can reliably receive and return information in a stacked state.

  According to the present invention, a wireless tag that holds information on an electronic device stored therein and transmits / receives the information by radio waves is attached, and a side portion of the upper surface portion and a side portion of the lower surface portion are respectively provided. In the electronic device storage tray formed so as to be stackable by providing the upper fitting portion and the lower fitting portion, the electric device storage tray is formed so as to be stackable only in one direction, and a constant side portion is formed. It is characterized by attaching a wireless tag to the location.

  In this configuration, the tray is formed in a shape that can be stacked only in one specific direction, so the lower tray only fits when the upper and lower trays are stacked in this specific direction. And the upper fitting portion of the lower tray are fitted, and the positions of the wireless tags are matched. On the other hand, when the orientation of the upper and lower trays does not match in a specific direction, that is, when the stacking direction is different between the upper and lower trays, the lower fitting portion of the upper tray and the upper fitting portion of the lower tray are not fitted, And the position of the wireless tag does not match.

  According to the present invention, a wireless tag that holds information on an electronic device stored therein and transmits / receives the information by radio waves is attached, and a side portion of the upper surface portion and a side portion of the lower surface portion are respectively provided. In a substantially rectangular parallelepiped storage tray formed so as to be stacked by providing an upper fitting portion and a lower fitting portion, at least one pair of opposing side portions of the upper fitting portion and the lower fitting portion Is formed in an asymmetric shape, and a wireless tag is attached to a specific position with respect to the asymmetric shape.

  In this configuration, since the upper fitting portion and the lower fitting portion are formed in an asymmetric shape, when the trays are stacked in the normal direction, the upper fitting portion of the upper tray and the upper fitting portion of the lower tray are used. And the position of the wireless tag coincides with each other. On the other hand, when the directions of the upper and lower trays are opposite, that is, when the trays are not stacked in the normal direction, the lower fitting portion of the upper tray and the upper fitting portion of the lower tray are not fitted, and the wireless tag The positions of do not match. For this reason, when trays are stacked in the normal direction, that is, when the positions of the wireless tags are aligned, these trays are stacked reliably, but in a direction different from the normal direction, that is, the positions of the wireless tags are not aligned. When trays are stacked on each other, these trays are not stacked reliably and are in an unstable stacked state. Since such an unstable stacking state can be easily confirmed by the operator, even if such a stacking occurs, the stacking can be immediately performed in the normal direction.

  The electronic device storage tray according to the present invention is characterized in that at least one corner of the upper fitting portion and the lower fitting portion is formed in a shape different from that of the other corner portions.

  In this configuration, by making one corner different from the other corners, opposing sides of the upper fitting portion and the lower fitting portion are simultaneously asymmetrical. For this reason, the asymmetrical shape of the fitting portion is formed by an easy shape change with respect to the rectangular parallelepiped shape.

  In addition, the electronic device storage tray according to the present invention is configured so that the corners of the side walls having the corners different in shape from the other corners of the upper fitting portion and the lower fitting portion are different from the corner portions of the other side walls. It is characterized by that.

  In this configuration, since one corner of the tray is different from the other corners, the operator can easily confirm the directionality of the tray.

  According to the present invention, since the trays are reliably stacked in the normal direction, the positions of the wireless tags provided on these trays match in the horizontal direction. Thereby, all the wireless tags can surely receive the radio waves from the external antenna, and the antennas can surely receive the radio waves returned from these radio tags. As a result, the type and in-process information of the electronic device module stored in each tray can be reliably acquired and updated.

An electronic device storage tray according to a first embodiment of the present invention will be described with reference to the drawings. In the following description, the electronic device storage tray is simply referred to as “tray”.
FIG. 1 is an external perspective view of an electronic device storage tray of the present embodiment. And (a) is the external appearance perspective view seen from the upper surface (electronic device module insertion surface) side, (b) is the external appearance perspective view seen from the lower surface side, (c) is an electronic device module storage state. It is the external appearance perspective view seen from the upper surface side.
As shown in FIG. 1, the tray 1 is formed in a substantially rectangular parallelepiped shape, and is provided with a recess 2 for storing an electronic device module surrounded by a side wall. The side wall is provided with a step that is depressed in order from each side end portion of the upper surface to the bottom surface of the recess 2 for storing the electronic device module, and the uneven portions 3a to 3d are formed by the step between the highest outer portion and the intermediate portion. Thereby, the upper fitting part 3 (3a-3d) is formed.

  On the other hand, the lower surface of the tray 1 has a shape facing the upper fitting portion 3 and protrudes from each side end portion at a position having a predetermined width from the side end portion, and the concave and convex portions 4a to 4d make the lower fitting portion. 4 is formed.

  The corner 1 of the tray 1 (the corner where the side walls including the concavo-convex portions 3b and 3c in FIG. 1 intersect) is formed with a cutout portion 5 having a shape cut from the apex by a predetermined length in both sides. And the corner | angular part corresponding to the notch part 5 of the upper fitting part 3 is the shape seen from the upper surface by providing the uneven part similar to the said uneven part 3a-3d by the predetermined width from the end surface of the notch part 5. A chamfered portion 6 having a chamfered shape is formed. Thereby, the shape seen from the upper surface of the upper fitting part 3 is a pentagonal shape in which one corner is cut off and the other three corners are perpendicular. On the other hand, the corner portion corresponding to the notch portion 5 of the lower fitting portion 4 has a shape as seen from the lower surface by providing an uneven portion similar to the uneven portions 4 a to 4 d with a predetermined width from the end surface of the notch portion 5. A chamfered portion 7 having a chamfered shape is formed. Thereby, the shape seen from the lower surface of the lower fitting part 4 is also a pentagonal shape in which one corner is cut off and the other three corners are perpendicular.

  With this structure, the upper fitting portion 3 has an asymmetric shape with respect to the center line in the long side direction of the tray 1 and the side having the uneven portion 3a and the side having the uneven portion 3b. The side having the concavo-convex part 3c and the side having the concavo-convex part 3d are asymmetrical with respect to the center line in the short side direction. Further, the lower fitting portion 4 has an asymmetrical shape with respect to the center line in the long side direction of the tray 1 and the side having the uneven portion 4b and the side having the uneven portion 4b. The side having the concavo-convex portion 4c and the side having the concavo-convex portion 4d are asymmetric with respect to the line.

  In addition, a groove having a predetermined width and depth is formed in the vicinity of the notch portion 5 of the tray 1 on the side of the electronic component storage recess 2 of the side wall having the uneven portion 3b, and the RFID tag having the RFID 11 in the groove. 10 is mounted and fixed with an adhesive or the like.

  The tray 1 is made of a highly compressible foam material and has a predetermined strength. And since this tray 1 is formed with a metal mold | die, once a metal mold | die is formed, the tray of the same shape can be formed in large quantities.

  Next, a method for using the tray 1 will be described.

  A plurality of electronic device holders (not shown) are formed on the bottom surface of the electronic device storage recess 2 of the tray 1, and a predetermined portion abuts on the electronic device holders as shown in FIG. An incomplete module (hereinafter referred to as “electronic device module”) 100 of an electronic device such as a liquid crystal television is disposed. As a result, the electronic device module 100 is held in the electronic device storage recess 2.

When stacking the plurality of trays 1 in which the electronic device modules 100 are stored in this manner, the operator stacks the notches 5 vertically, that is, as shown in FIG.
2A and 2B are perspective views showing a stacked state of electronic device storage trays, where FIG. 2A is an exploded perspective view and FIG. 2B is an external perspective view after stacking.
As shown in FIG. 2, when stacking the trays 1a to 1c, the trays 1a to 1c are stacked so that the cutout portions 5 are in the same position. At this time, the corner portions of the side walls of the trays 1a to 1c are provided with the cutout portions 5 at only one corner, so that the operator can easily match the stacking directions of the trays 1a to 1c.

  Here, when the trays 1a to 1c have the above-described structure and the stacking directions coincide, the lower fitting portion 4 of the tray 1a and the upper fitting portion 3 of the tray 1b are fitted, and the lower fitting portion of the tray 1b. 4 and the upper fitting portion 3 of the tray 1c are fitted. Thereby, tray 1a-1c can be stacked stably. When stacked in this way, the mounting positions of the wireless tags 10a to 10c on the respective trays 1a to 1c are the same, so that the horizontal positions of the wireless tags 10a to 10c coincide. That is, the wireless tags 10a to 10c are arranged along the stacking direction (vertical direction) of the trays 1a to 1c.

  Here, if the stacking directions of the trays 1a to 1c do not match, that is, the stacks are made so that the cutout portions 5 of the trays 1a to 1c do not match, a gap is generated between the trays as shown in FIG. It becomes an unstable stacking state.

FIG. 3 is an external perspective view showing a stacked state of trays when the stacking directions are not aligned.
Thus, the positions of the notches 5 are not aligned and a gap is generated, so that the operator can easily confirm that these trays are not stacked in the normal direction. As a result, the operator can immediately stack the trays in the normal direction.

  Next, when the stacked trays 1a to 1c reach a predetermined position in the process, an information acquisition signal is transmitted from the antenna 50 installed at this position, and this information acquisition signal is attached to each tray 1a to 1c. The RFIDs 11a to 11c of the wireless tags 10a to 10c receive the information signals corresponding to the information acquisition signals. Examples of the information signal include the types of modules stored in the trays 1a to 1c, the process progress status, and the like. When this information signal is received by the antenna 50, the control device connected to the antenna 50 analyzes this and obtains information on the modules stored in the trays 1a to 1c. Based on this information, a predetermined work is performed. If the module state changes (if the process proceeds), new in-process information on the module in the tray is transmitted from the control device via the antenna 50, and the information signals are received by the RFIDs 11a to 11c. The information stored in the internal memory is updated.

  By adopting such a configuration, it is possible to reliably and accurately manage the module in progress.

Next, an electronic device storage tray according to a second embodiment will be described with reference to FIG.
FIG. 4 is an external perspective view of the electronic device storage tray as viewed from the upper surface side.
The electronic device storage tray shown in FIG. 4 has a shape in which one corner of the upper fitting portion 3 and the lower fitting portion 4 is different from the other corners without providing the notch 5 at the corner of the side wall of the tray 1. The other structure including the shapes of the upper fitting portion 3 and the lower fitting portion 4 is the same as the electronic device storage tray shown in FIG.
Even in such a configuration, if the stacking direction of the trays does not match, the stacking state becomes unstable and a gap is formed between the trays. Therefore, the operator can easily recognize this state and stack the trays accurately. Thereby, the positions of the wireless tags can be matched, and a tray that can reliably acquire and update information can be configured.

Next, an electronic device storage tray according to a third embodiment will be described with reference to the drawings.
FIG. 5 is an external perspective view of the electronic device storage tray of the present embodiment.
The electronic device storage tray 1 shown in FIG. 5 includes a protrusion 8 that protrudes at a predetermined length in the center direction of the tray 1 at the approximate center of the upper fitting portion 3 on the long side wall. 4 is provided with a concave portion 9 that is fitted to the protruding portion 8 and that is recessed by a predetermined depth in the central direction of the tray 1. Other configurations are the same as those of the conventional tray.
Even in such a configuration, as in the first and second embodiments, the trays cannot be reliably stacked unless the stacking direction is matched. Therefore, the operator visually recognizes the stacking state, and securely holds the tray. Can be stacked. Thereby, the positions of the wireless tags can be matched, and a tray that can reliably acquire and update information can be configured.
