  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings of the examples. FIG. 1 is an external view of an electronic component storage tray 1 according to an embodiment of the present invention. FIG. 1 (a) is a perspective view and FIG. 1 (b) is a plan view.

  The tray 1 is made of a flat box-shaped plastic frame, but is not limited to plastic. The tray 1 includes an upper frame 2, a lower frame 3, a vertical frame 4, and a vertical beam 5 and a horizontal beam 6 which are disposed on the bottom surface. The substrate is a flat plate composed of vertical bars 5 and horizontal bars 6. The vertical beam 5 and the horizontal beam 6 are arranged in a grid pattern vertically and horizontally at a predetermined interval on a plane near the bottom surface, and each of the grids surrounded by the vertical and horizontal beams forms a small section for accommodating an electronic component. . That is, one electronic component is accommodated in each grid.

  In this embodiment, the size of the tray 1 is a rectangle of about 90 × 100 mm and the height is about 15 mm. However, the present invention is not limited to this example. The upper frame 2 is made of a strip having a width of 7 mm and a thickness of about 0.5 mm, and is disposed so as to surround the entire upper side surface of the tray 1. The upper surface of the tray is open, and other trays having the same shape are placed from the top, and stacked in multiple stages.

  The lower frame 3 is formed of a thin square bar having a cross section of about 2 × 1 mm, and is disposed so as to surround the entire circumference of the bottom surface. The vertical frame 4 has a rectangular bar shape slightly narrowed on the lower side, and a plurality of vertical frames 4 are arranged so as to connect the upper frame 2 and the lower frame 3 vertically at a predetermined interval.

  In this embodiment, the interval between the vertical frames 4 corresponds to the dividing lines of the small sections, that is, the positions of the vertical beam 5 and the horizontal beam 6. The vertical beam 5 and the horizontal beam 6 are arranged in parallel with each side of the tray 1 at a predetermined interval. In this embodiment, a cross parallel to the long side of the tray 1 is called a vertical cross.

  Both the vertical beam 5 and the horizontal beam 6 are attached near the lower end of the vertical frame 4 (slightly above the lower frame 3). Each of the small sections is provided with a diagonal beam 19 that is slanted between one side of the vertical beam 5 and one side of the horizontal beam 6, and a plurality of pins protruding upward. Will be described later.

  2A and 2B are diagrams illustrating a state in which the trays 1 of the present embodiment are stacked. FIG. 2A is a side view before stacking, and FIG. 2B is a side view illustrating a state after stacking. As shown in FIGS. 2A and 2B, the tray 1 includes an upper frame 2, a lower frame 3, a vertical frame 4, vertical and horizontal bars, and the like. In this figure, the short side of the tray 1 is viewed from the side, and only the side of the side rail 6 on the front side is shown. Further, a locking member 7 (which will be described later) protrudes downward in the longitudinal center of the upper frame 2, and this portion of the lower frame 3 is cut away.

  In the tray 1 of the present embodiment, the upper frame 2 and the vertical frame 4 are formed to be slightly smaller toward the lower side. That is, the outer dimension X of the lower frame 3 is slightly smaller than the inner dimension Y of the upper frame 2 on both the long side and the short side, and as shown in FIG. When pushed in from the upper side of the tray 1b, about 1/3 of the lower side of the tray 1a enters the upper portion of the tray 1b and is stacked.

The electronic component storage tray of the present invention is characterized in that in addition to the above-described configuration, the following locking mechanism, positioning mechanism, chip (electronic component) rotation prevention mechanism, and vertical movement prevention mechanism are provided.
(1) Locking mechanism: A tray-removable locking mechanism that fixes upper and lower trays stacked in multiple stages to prevent detachment during conveyance and cleaning, and can be easily removed when necessary.
(2) Positioning mechanism: A positioning mechanism for stacking the trays in a one-way manner so that one of the four corners of the trays coincides with the upper and lower trays.
(3) Chip rotation prevention mechanism: a mechanism for fixing the chips accommodated in each small section of the tray so that they do not rotate in a horizontal plane during conveyance and cleaning.
(4) Chip vertical movement prevention mechanism: A mechanism that prevents vertical movement of the chip accommodated in each small section of the tray so that the chip does not move up and down during transportation and cleaning.
(5) A vacuum pack bag breakage prevention mechanism that prevents the vacuum pack bag from being damaged when vacuum-packing a plurality of stacked trays after cleaning.
It is a feature of the present invention that each of these mechanisms can be realized with a simple structure.

  First, the locking mechanism will be described. FIG. 3 is an explanatory diagram of a locking mechanism in the present embodiment. This locking mechanism is constituted by a pair of locking members 7 provided in the vicinity of the center of two opposite sides (short pieces in this embodiment) of the upper frame of the tray 1. FIG. 3A is a perspective view of the locking member 7 portion (A portion of FIG. 1A) viewed from the outside, and FIG. 3B is a perspective view of the locking member 7 portion viewed from the inside. FIG. 3 (c) is a longitudinal sectional view showing a state where the locking members 7 of the upper and lower trays are engaged.

  As shown in FIG. 3A, the locking member 7 is a strip-shaped member extending downward from the upper frame 2 and is formed integrally with the upper frame. A locking claw 8 is formed at the outer lower end of the locking member 7 so as to spread over the entire width in the lateral direction. The upper surface of the locking claw 8 is substantially horizontal.

  On the other hand, as can be seen in FIG. 3B, a step 9 is formed in the vicinity of the upper end of the locking member 7 (the portion joined to the upper frame) that extends across the entire width in the lateral direction. The step 9 is a step whose upper part protrudes inward. The bottom surface of the step 9 is substantially horizontal. A shallow vertical groove 10 is formed outside the portion where the locking member 7 is joined to the upper frame 2 for facilitating the fitting of the locking member.

  When the upper and lower trays are overlapped, as shown in FIG. 3C, the lower portion of the locking member 7a of the upper tray is elastically deformed, and the locking claw 8a at the lower end thereof is locked to the locking member of the lower tray. 7b enters (indicated by arrow A in FIG. 3C), and the lower end of the locking claw 8a engages with the step 9b of the lower tray to prevent separation between the upper and lower trays.

  When removing the upper and lower trays, if the locking member 7a is pushed in the direction of arrow A by the force of a human finger, the locking member 7a is easily deformed, and the engagement between the locking claw 8a and the step 9b is released. be able to. Thus, one feature of the present invention is that the upper and lower trays can be detachably engaged with a simple mechanism.

Next, the positioning mechanism will be described. First, the reason why positioning is necessary will be described. Since the rectangular trays having the same shape overlap even at a position where one side is rotated by 180 °, there are two ways of overlapping.
In the tray of this embodiment, the diagonal beam 19 is located at a position deviating from the center line of the small section, so that the diagonal beam 19 is positioned in the same position between the upper and lower trays (hereinafter referred to as “stacking in the same direction”). There is a method of overlapping (hereinafter referred to as point-symmetrical overlapping) where point symmetry is achieved.

  Since the direction of the chip accommodated in the small section depends on the position of the oblique beam 19, the direction of the chip changes for each tray in the point-symmetric stacking. Since the chip is usually stored and taken out by an automatic assembling apparatus, it is necessary to avoid the point-symmetrical stacking. In other words, the reason why the trays need to be positioned is that they must be stacked so that one particular corner of the four corners of the tray always coincides with the upper and lower trays.

  FIG. 4 is a diagram for explaining the configuration of the positioning mechanism in the present embodiment, and is an enlarged perspective view showing one corner of the tray 1 (B section in FIG. 1A). As seen in FIG. 4, a positioning pin 12 that is upright via a support member 11 is attached to the inside of the upper frame 2 of this corner.

  The positioning pin 12 is substantially cylindrical and has a diameter slightly larger in the lower part, and its length is about 2/3 of the height of the tray 1. In addition, a protruding portion 13 having a slightly larger area is provided at one corner (corner portion) of the lower frame 3, and a through hole 14 is provided near the center thereof.

  In the other three corners of the tray 1, the positioning pins 12 are not provided. Although there is an overhanging portion 13 of the lower frame 3, the through hole 14 is not provided. Therefore, in the case of stacking in the same direction, the positioning pin 12 of the lower tray is inserted into the through hole 14 of the upper tray, so that the upper tray can be pushed into the lower tray when stacked.

  However, in the point symmetric stack, the through hole 14 is not provided in the upper tray, so the head of the positioning pin 12 of the lower tray hits the lower surface of the overhanging portion 13 of the upper tray, and the upper tray reaches the inside of the lower tray. I can't push it in. In that case, an operator may rotate one tray by 180 ° and stack it. This positioning mechanism is also simple in structure and can be manufactured at low cost.

  Next, an electronic component rotation prevention mechanism will be described. FIG. 5 is an explanatory view of the rotation preventing mechanism in the present embodiment. FIG. 5A is a perspective view showing an example of the shape of the electronic component housed in the tray 1 of the present embodiment, and FIG. The perspective view which expands and shows the small division of the tray 1 of an Example, FIG.5 (c) is a top view which shows the state which accommodated the electronic component in the small division.

  The electronic component shown in FIG. 5A is used for a hard disk, and the electronic component 15 includes a main body portion 16 and a mounting portion 17 on the back surface thereof. The main body 16 has a plate shape with a size of about 13 × 7 mm. On the back surface of the main body portion 16, a mounting portion 17 is formed upright in the shape of a dorsal fin almost at the entire center in the longitudinal direction, and one lock hole 18 is provided near the end of the mounting portion 17.

  As shown in FIG. 5 (b), each small section of the tray 1 is divided into rectangles by a vertical beam 5 and a horizontal beam 6, from the center of the horizontal beam 6 to the end of the vertical beam 5. A leaning pier 19 is hung. On the inclined beam 19, three tall pins and one low pin are erected upright.

  Among these pins, the tall pins at both ends are the positioning pins 20a and 20b, the tall pin among the two inner pins is the lock pin 21, and the inner short pin is described later. This is a holding pin used for the vertical movement prevention mechanism. The tip of the lock pin 21 is tapered so that it can be easily inserted into the lock hole 18. Further, a reinforcing bar 22 is suspended from the vicinity of the center of the oblique beam 19 to the vicinity of the center of the vertical beam 5 on the opposite side.

  In order to accommodate the electronic component 15 in the small section of the tray 1, the main body of the electronic component 15 is made upright (the mounting portion is horizontal), and the lock pin 21 is inserted into the lock hole 18 of the mounting portion 17. In this state, as shown in FIG. 5C, the back surface of the main body portion 16 comes into contact with the outer edge of the positioning pin 20a, and the back of the mounting portion 17 comes into contact with the outer edge of the positioning pin 20b. Therefore, if the electronic component 15 tries to rotate in the direction of the arrow B, the electronic component 15 hits the positioning pin 20a. If the electronic component 15 tries to rotate in the direction of the arrow C, the electronic component 15 hits the positioning pin 20b. Can be prevented.

  FIG. 6 is an explanatory view of a rotation preventing mechanism in another embodiment of the present invention. FIG. 6 (a) is a perspective view showing the shape of the electronic component 15 in this embodiment, and FIG. 6 (b) is this embodiment. FIG. 3 is an enlarged perspective view showing a small section of the tray 1. Similarly to the electronic component 15 shown in FIG. 5A, the electronic component 15 shown in FIG. 6A is also composed of a main body portion 16 and a dorsal fin mounting portion 17 provided on the back surface thereof. It is. However, this electronic component 15 is different from the electronic component of FIG. 5A in that two lock holes 18a and 18b are provided in the mounting portion 17.

  The configuration of the vertical beam 5, the horizontal beam 6, the diagonal beam 19, the reinforcing beam 22 and the like of each small section of the tray 1 in this embodiment is the same as that of FIG. This is different from FIG. That is, the two lock pins 21a and 21b and the short pressing pin are erected and no positioning pin is provided. In order to accommodate the electronic component 15 in the small section of the tray 1, the mounting portion 17 of the electronic component 15 is leveled, and the lock pins 21 a and 21 b are inserted into the lock holes 18 a and 18 b of the mounting portion 17, respectively. Since the lock pins 21a and 21b fit into the lock holes 18a and 18b without loosening, the electronic component 15 can be prevented from rotating in the horizontal plane by fixing with the two lock pins.

  FIG. 7 is an explanatory view of the vertical movement preventing mechanism in the present embodiment. FIG. 7A is a perspective view of the small section of the tray 1 of the present embodiment as viewed from above, and FIG. FIG. 7C is a side view showing a state in which the electronic component 15 is fixed by the upper and lower trays. In FIG. 7 (a), an upright holding pin 23 having a short height is erected on the oblique beam 19 together with two positioning pins 20 a and 20 b and a lock pin 21. On the other hand, as shown in FIG. 7B, a lower downward pressing pin 24 is provided on the lower side of the oblique beam 19 at a position corresponding to the upward pressing pin 23. When the upper and lower trays are overlapped, as shown in FIG. 7B, the mounting portion 17 of the electronic component 15 has no gap between the downward pressing pin 24 of the upper tray and the upward pressing pin 23 of the lower tray. Sandwiched. Therefore, the electronic component main body 16 can be prevented from moving up and down. This vertical movement prevention mechanism is also simple in structure and can be manufactured at low cost.
