[Diagram 5] 1 is an external view of a device tray according to a first embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.
[0014] FIG. 1 is a schematic diagram of a device tray 101 as an embodiment of the present invention, as viewed from above. The device tray 101 includes a plurality of first linear members 102 extending in parallel in one direction (X direction) and a plurality of second linear members 103 extending in parallel in a direction (Y direction) intersecting the plurality of first linear members 102. The plurality of second linear members 103 are arranged on the plurality of first linear members 102 (Z direction). Each of the plurality of openings 104 is formed so as to be surrounded by two adjacent first linear members among the plurality of first linear members 102 arranged in parallel and two adjacent second linear members among the plurality of second linear members 103 arranged in parallel. A device 105 can be stored in each of the plurality of openings 104.
[0015] The intersection angle between the multiple first linear members 102 and the multiple second linear members 103 is approximately 90°, but the intersection angle may be set according to a specific application of the device tray 101. For example, the intersection angle may be set according to the shape of the device 105 to be stored in the opening 104 of the device tray 101. In addition, the distance between two adjacent first linear members and the distance between two adjacent second linear members may also be set according to a specific application of the device tray 101.
[0016] 2 is a schematic diagram of the device tray 101 as viewed from the side. A plurality of first linear members 102 extending parallel to the X direction and a plurality of second linear members 103 extending parallel to the Y direction are alternately stacked to form the device tray 101 having an opening 104. The device tray 101 has four legs 106 below the first linear member 102 in the lowest layer, and in FIG. 2, two legs 106 on the front side of the page are shown. The legs 106 are bonded to the first linear member 102 in the lowest layer.
[0017] 3 is a bottom view of the leg portion 106. A first groove 102' extending in the X direction and engageable with the first linear member 102 is provided on the bottom surface of the leg portion 106, and a second groove 103' extending in the Y direction and engageable with the second linear member 103 is provided. The first groove 102' and the second groove 103' intersect at approximately 90°, similar to the first linear member 102 and the second linear member 103.
[0018] The first groove 102' and the second groove 103' can be formed by various methods. For example, a method of mechanically performing countersinking on the bottom surface of the leg 106 where no groove is formed, a method of pressing a stamp, molding by a 3D printer, etc. may be mentioned. In addition, the leg 106 in which the first groove 102' and the second groove 103' are formed may be manufactured by pouring the material of the leg 106 into a mold of the leg 106 in which the first groove 102' and the second groove 103' are formed in advance. In addition, the leg 106 may be formed by additive manufacturing so that the portions of the first groove 102' and the second groove 103' are formed.
[0019] 4 shows an enlarged side view of the leg 106. The first groove 102' and the second groove 103' each have a depth d 2 and d 3 and width w 2 and w 3 The depth d of the first groove 102′ and the second groove 103′ 2 and d 3The width w of the first groove 102' and the second groove 103' may be 20% to 300% of the height of the first linear member 102 and the second linear member 103, respectively, but in order to stably stack multiple trays, it is preferable that it is 100% to 250%. In addition, when stacking trays with another material sandwiched between them, it may be 100% to 300%. 2 and w 3 may be 110% to 200% of the width of the first linear member 102 and the second linear member 103, respectively.
[0020] FIG. 5 is an external view of a device tray 101 of the present invention seen from above, showing how a first linear member 102 and a second linear member 103 intersect with each other.
[0021] At least one of the first linear members 102, the second linear members 103, and the legs 106 may be configured to have a heat capacity that allows the device 105 stored in the opening 104 of the device tray 101 to be heated, and may be made of a material suitable for heating the device 105. For example, resins include epoxy resin, acrylic resin, polyimide resin, polyetherimide resin, polyethersulfone resin, liquid crystal polymer, and fluorine-based copolymer resin. Metals include iron, nickel, copper, titanium, tungsten, aluminum, platinum, silver, and alloys thereof (for example, iron-chromium-nickel alloy). Furthermore, from the viewpoint of making the device tray 101 excellent in heat resistance, at least one of the first linear members 102, the second linear members 103, and the legs 106 may be made of ceramics. The ceramics may include at least one of alumina, silicon carbide, silicon nitride, zirconia, mullite, zircon, cordierite, aluminum titanate, magnesium titanate, magnesia, titanium diboride, boron nitride, boron carbide, and the like, and in particular, the ceramics may include alumina, mullite, cordierite, zirconia, or silicon carbide. Since ceramics as a material have excellent rigidity and heat resistance reliability, when the first filament member 102, the second filament member 103, and the leg portion 106 are made of ceramics, a ceramic device tray 101 having excellent rigidity and heat resistance reliability can be obtained. Furthermore, when storing a ceramic device 105, the ceramic device tray 101 can be used in high-temperature processes, such as repeatedly applying the device 105 to a firing process. Furthermore, when the device tray 101 is rapidly heated and cooled, the ceramic may contain silicon carbide, and in this case, the surface may be coated with less reactive zirconia, yttria, etc. Some of the plurality of first filament members 102, the plurality of second filament members 103, and the legs 106 may be made of the same material or different materials.In particular, when the same material is selected for the first filamentary member 102, the second filamentary member 103, and the legs 106, the difference in thermal expansion between the members becomes small, and the thermal stress generated during heating and cooling is reduced, resulting in a device tray 101 that is less likely to crack or deform even during firing or rapid cooling.
[0022] In this embodiment, the legs 106 are provided at the four corners of the lower surface of the device tray 101, but the number and installation locations of the legs 106 are not limited to this as long as the structure allows the device tray 101 to be stably placed on a flat surface. For example, the legs 106 may be provided at a total of three locations, namely, two adjacent corners and the center of one opposing side, or at a total of three locations, namely, two adjacent sides and opposing corners. In addition, for example, the legs 106 may be provided at a total of six locations, namely, the four corners of the lower surface and the center of two opposing sides. In this way, the installation locations of the legs 106 are not limited to the four corners of the lower surface, and the number of legs is not limited to four. Any structure may be used as long as the device tray 101 can be stably placed on a flat surface.
[0023] Also, instead of the rectangular device tray 101 as in this embodiment, it is possible to use a triangular or polygonal device tray having 5 or more sides. When the device tray is triangular, stable placement can be achieved by providing legs at the three corners or the center of each side of the lower surface of the device tray. When the device tray is polygonal having 5 or more sides, the legs may be provided at each corner of the lower surface of the device tray or at the center of the sides.
[0024] In this embodiment, the legs 106 are rectangular parallelepipeds, and the first groove 102' and the second groove 103' that intersect at approximately 90° are provided on the lower surface of the legs 106, but the shape of the legs 106 and the intersecting angle of the first groove 102' and the second groove 103' are not limited to this. The legs 106 may be cylindrical or triangular prisms, etc., and it is sufficient that the first groove 102' and the second groove 103' are provided in a direction that engages with the first linear member 102 and the second linear member 103 on the upper surface of the device tray.
[0025] Although the above description has been given with respect to a particular embodiment, it will be apparent to those skilled in the art that the present invention is not limited thereto, and that various changes and modifications can be made within the principles of the present invention and the scope of the appended claims.
