Fig. 2b is a plan view of the tray unit of fig. 2 a. Fig. 3a is a perspective view of the bottom tray of fig. 2a, and fig. 3b is a plan view of the bottom tray of fig. 3 a. Fig. 4a is a perspective view of the inner tray of fig. 2a, and fig. 4b is a plan view of the inner tray of fig. 4 a. Fig. 5a is an exploded perspective view showing a state where the first load target member is loaded on the tray unit of fig. 2 a. Fig. 5b is an exploded perspective view illustrating a state where the tray unit of fig. 2a is loaded with the second load target component without the inner tray.

Referring to fig. 1 to 5b, the common tray 1 is used in a case where a plurality of components having different sizes are loaded. For example, the component to be mounted may be an electronic component or a display device. Examples of the display device include an organic light emitting display device, a micro LED display device, a nano LED display device, a quantum dot display device, a liquid crystal display device, a plasma display device, a field emission display device, an electrophoretic display device, and an electrowetting display device.

The components to be loaded can be stored or transported by being loaded on the common tray 1. The common tray 1 can be used for loading the following components: different types of elements of different sizes; or the same element but having different sizes after the process.

For example, the display device includes a substrate, and is completed by forming a plurality of thin films on the substrate and modularizing the thin films. The size may be different for the intermediate display device before modularization and the display device after modularization. For example, the size of a display device combined with a stand or a chassis, etc., through a modular process may be increased compared to before. The common tray 1 is configured to include an inner tray 200 detachably mounted to the bottom tray 100, so that not only the intermediate display device before modularization but also a display substrate completed in modularization can be loaded. The detailed description thereof will be described later.

The common trays 1 may have substantially the same shape and structure. A plurality of the common trays 1 may be stacked on each other. As shown in fig. 1, a plurality of common trays 1 having substantially the same structure may be stacked in the height direction. Although the number of stacks of the common tray 1 is not limited to this, it may be 2 to 150. In the case of the common tray 1 on which the organic light emitting display device is mounted, it is preferable in terms of space utilization and stability of the laminated structure when the common trays 1 of 10 to 32 are laminated. In one embodiment, 16 common trays 1 carrying organic light emitting display devices may be stacked.

The plurality of common trays 1 may be stacked in a state where the common trays 1 are loaded with the counter elements. In a state where the common trays 1 are stacked, the load target components may be spaced from the common tray 1 located at the upper portion (for example, the lower face of the bottom tray) without contacting thereto. This can be achieved by designing the height of the loading space of each common tray 1 to be larger than the thickness of the components to be loaded.

The stacked structure shown in fig. 1 may facilitate loading a larger number of load target elements in a limited space. As will be described later, the common trays 1 are fixed to each other in a stacked state, and a stable stacked structure can be maintained.

Each of the common trays 1 may include a plurality of tray units Q. Each tray unit Q is provided with a loading portion including a loading space so that one loading object component can be loaded on the corresponding loading portion. The loading portions of the tray units Q may have substantially the same shape. The tray units Q may be arranged in an array shape. Fig. 1 exemplarily shows a case where the tray units Q are arranged in 3 rows and 3 columns, but is not limited thereto.

The common tray 1 includes a bottom tray 100 and an inner tray 200 configured to be mountable within the bottom tray 100.

The bottom tray 100 includes one or more first loading parts 110 and a first edge part 120 surrounding the first loading parts 110. Each tray unit Q is provided with one first loading part 110. The first edge portion 120 includes a first outer edge portion disposed at an outer edge of the bottom tray 100 and a first inner edge portion passing between the plurality of first loading portions 110. The first loading part 110 includes a first bottom surface having a thickness smaller than that of the first edge part 120. The first loading space of the first loading portion 110 is defined by the inner side surface of the first edge portion 120 and the first bottom surface. The first loading space is loaded with the loading object member and/or the inner tray 200. In a state where the inner tray 200 is mounted in the first loading space, the first load target components 20 of the first size are arranged in the first loading space, specifically, in the second loading space of the inner tray arranged in the first loading space. In the case where the inner tray 200 is not mounted in the first loading space, the second loading object member 10 of the second size may be directly disposed in the first loading space. Here, the second size may be larger than the first size.

The first edge portion 120 supports the outer side surface of the inner tray 200 and/or the second target object element 10 loaded in the first loading space in a state of being in close contact therewith, so that the loaded inner tray 200 and/or the second target object element 10 can be prevented from moving in the horizontal direction.

The first medial edge portion may include a medial bonding groove 122 disposed thereon. Specifically, the inner coupling grooves 122 may be provided along a line connecting the adjacent tray units Q. The inner coupling grooves 122 may facilitate the operations of mounting the inner tray 200 and/or the second load object member 10 to the bottom tray 100 and detaching the inner tray 200 and/or the second load object member 10 from the bottom tray 100.

The first medial edge portion may include a medial bonding protrusion 124 disposed below. The inner side coupling protrusion 124 may be disposed under the first inner side edge portion corresponding to the inner side coupling groove 122 located above the first inner side edge portion.

In the structure in which a plurality of bottom trays 100 are stacked in the height direction, the inner coupling protrusions 124 and the inner coupling grooves 122 are fastened to each other in the thickness direction, so that the bottom trays 100 of the stacked structure may be prevented from being separated in the horizontal direction. In an embodiment, the length of the protruding portion of the inner coupling protrusion 124 may be greater than the depth of the inner coupling groove 122. In this case, a predetermined space can be secured between the adjacent bottom trays 100 in the stacked structure of the bottom trays 100, so that the loading object components can be prevented from being damaged. Fig. 3a and 3b illustrate the base tray 100 in which the inner coupling grooves 122 are formed at the upper, lower, left, and right sides of the first loading portion 110, but not limited thereto, and the inner coupling grooves 122 may not be formed in a direction in which there is no adjacent tray unit Q (refer to fig. 1).

The bottom tray 100 may also include a first protective groove 112, a stopper 140, and a lateral groove 150.

The first protection groove 112 may be located at four corners of the first loading part 110. The first protection groove 112 may have a fan-shaped cylindrical shape having a bottom surface formed by a fan shape: the vertex at which the straight portions of the edges of the first loading part 110 intersect is defined as a center, and 270 ° formed by the straight portions of the edges of the first loading part 110 intersecting is defined as a center angle. When the inner tray 200 or the second component to be loaded 10 is loaded on the bottom tray 100, the inner tray 200 or the second component to be loaded 10 does not directly contact the bottom tray 100 due to the first protective groove 112, and thus damage can be prevented.

A plurality of stoppers 140 arranged at a predetermined interval may be located at an outer side of the first edge portion 120. The stopper 140 may have a groove shape having a concave-convex structure in a horizontal direction, and may have a shape in which an upper surface is recessed from an upper surface of the outer edge portion and a lower surface is protruded from a lower surface of the outer edge portion in a vertical direction. In the bottom tray 100 of the stacked structure, the protruding portion below the stopper 140 and the recessed portion above the stopper 140 of the lower bottom tray are fastened to each other in the thickness direction, so that the bottom tray 100 can be prevented from being detached in the horizontal direction.

A plurality of side grooves 150 may be provided on the outer side of the first edge portion 120. Specifically, the lateral groove 150 may be formed in a concave-convex structure having a semicircular shape in the medial lateral direction. In the bottom tray 100 of the stacked structure, the contact area is increased due to the side grooves 150 having the concavo-convex structure, so that the bottom tray 100 can be prevented from being detached in the horizontal direction.

The bottom tray 100 may include more than one first loading space. The first loading spaces of the bottom tray are respectively installed with one inner tray 200.

The inner tray 200 includes a second loading portion 210 and a second rim portion 220 surrounding the second loading portion 210. Each tray unit Q is provided with one second loading part 210. The second loading part 210 includes a second bottom surface having a thickness smaller than that of the second edge part 220. The second loading space of the second loading portion 210 is defined by the inner side surface of the second edge portion 220 and the second bottom surface. A load object member is loaded in the second loading space. Specifically, in a state where the inner tray 200 is mounted to the first loading space of the bottom tray 100, the first load target components 20 of the first size are arranged in the second loading space of the inner tray 200 arranged in the first loading space.

The second edge portion 220 supports the outer side surface of the first loading object member 20 loaded in the second loading space in a state of being just fitted, so that the loaded first loading object member 20 can be prevented from moving in the horizontal direction.

The outer side of the second edge portion 220 of the inner tray 200 can include a first fastening structure 230 and the inner side of the first edge portion 120 of the bottom tray can include a second fastening structure 130. The first and second fastening structures 230 and 130 have shapes that can be fastened to each other. Either one of the first fastening structure 230 and the second fastening structure 130 may be a fastening groove, and the other may be a fastening protrusion. For example, the first fastening structure 230 may be a fastening groove and the second fastening structure 130 may be a fastening protrusion, and conversely, the first fastening structure 230 may be a fastening protrusion and the second fastening structure 130 may be a fastening groove.

The inner tray 200 may further include a second protective groove 212 and a second protruding edge portion 224. The second protection grooves 212 may be located at four corners of the second loading part 210. The second protection groove 212 may have a fan-shaped cylindrical shape having a bottom surface formed by a fan shape: the vertex at which the long side and the short side of the second mounting portion 210 intersect is defined as the center, and 270 ° formed by the intersection of the long side and the short side is defined as the center angle. When the first component to be loaded 20 is loaded on the inner tray 200, the first component to be loaded 20 does not directly contact the inner tray 200 due to the presence of the second protection groove 212, and thus damage can be prevented.

The second protrusion edge portion 224 having the same width as the second edge portion 220 may have a shape protruding toward the outside of the inner tray 200 in parallel with the second edge portion 220. At the centers of the short side portions of the opposite sides of the second edge portion 220, there may be respectively provided a second protruding edge portion 224 having a short length perpendicular to the protruding direction. One second projecting edge portion 224 having a long length perpendicular to the projecting direction may be provided at the center of the long side portion side of the second edge portion 220, and two second projecting edge portions 224 having a short length perpendicular to the projecting direction may be provided bilaterally symmetrically on the other side of the long side portion.

In a state where the inner tray is disposed in the first loading portion 110, the first component to be loaded 20 of the first size may be loaded in the second loading portion 210 of the inner tray, and in a state where the inner tray is not disposed in the first loading portion 110, the second component to be loaded 10 of the second size larger than the first size may be loaded in the first loading portion 110.

As an example, the first load object member 20 may be an intermediate display device before being modularized, and the second load object member 10 may be a display device after the intermediate display device is modularized.

Referring to fig. 6 to 8, as described above, the upper surface portion of the inner coupling groove 122 is recessed and the lower surface portion may be the protruding inner coupling protrusion 124. When the common trays 1 are stacked, the inner coupling protrusion 124 is fastened to the inner coupling groove 122 of the adjacent bottom tray, so that the common tray 1 can be prevented from being separated in the horizontal direction.

The base tray 100 and the inner tray 200 may be constructed using various materials, and preferably, include an injection-moldable polymer compound in consideration of process convenience, manufacturing costs, and the like. As such a polymer compound, polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), Acrylonitrile-Butadiene-Styrene copolymer (ABS), Polystyrene (PS), and the like can be used. As an example, the bottom tray 100 and the inner tray 200 may be constructed using the same material. As another example, the bottom tray 100 and the inner tray 200 can be constructed using different materials. However, the material of the tray according to the present invention is not limited thereto.
