Description

Technical Field

[0001] This application belongs to the field of pallet technology, and in particular relates to a packaging pallet and packaging structure. Background Technology

[0002] Packaging structural components commonly used in the transportation and turnover of products such as display panels include pallets, partitions, cushioning covers, and cartons. Among them, pallets are an important component in the product packaging structure, playing a vital role in supporting, limiting, and cushioning the display panels.

[0003] Trays are typically made of flexible plastics such as polyethylene terephthalate (PET) and polypropylene (PP). Different initial sheet thicknesses are selected based on the varying stretching heights after thermoforming to ensure the tray's strength and toughness. Many display panels also include studs and other structural components. The overall height of display panel products is relatively high, requiring thicker sheet material for thermoforming, resulting in extremely high costs. Furthermore, due to the large stretching area after thermoforming, the tray's thickness is uneven, with some areas showing significantly reduced thickness. This reduces the tray's load-bearing and cushioning performance, failing to effectively protect the display panel and other products.

[0004] Currently, external pads and cushioning covers are commonly used to enhance the pallet's cushioning protection of the product. These cushioning materials are usually applied by workers, which results in low work efficiency and poor application quality. Residual adhesive or cushioning material often falls off. The application space for cushioning material in corners is too small to ensure application accuracy, which cannot effectively improve the pallet's load-bearing and cushioning performance. The transportation safety of the display panel cannot be guaranteed. Summary of the Invention

DETAILED DESCRIPTION

[0040] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are examples for explaining the present application and should not be understood as limiting the present application.

[0041] Reference is made below to Figures 1-14 a packaging tray according to an embodiment of the present application.

[0042] The packaging tray of the embodiment of the present application can be used to place a display panel, which can be a liquid crystal display panel or an Organic Light-Emitting Diode (OLED) display panel.

[0043] As Figure 1 shown, the packaging tray of the embodiment of the present application comprises a tray housing 200 and at least one reinforcing member 100.

[0044] In this embodiment, the tray shell 200 is used to place the display panel, the tray shell 200 is formed by plastic injection, and the tray shell 200 includes at least one area to be reinforced.

[0045] It should be noted that the area to be reinforced refers to a weak area with a significantly reduced thickness after the tray shell 200 is formed by plastic injection, or an area that plays an important supporting role for the display panel carried by the tray shell 200. The area to be reinforced can be a corner position of the tray shell 200 or other positions that need to be reinforced. The position of the area to be reinforced is determined according to the weak area of the tray shell 200 formed by plastic injection and the product characteristics of the display panel carried.

[0046] In actual execution, the material of the tray shell 200 is plastic, and the material of the reinforcing member 100 can be plastic or other materials.

[0047] In this embodiment, the reinforcing member 100 corresponds to the area to be reinforced one by one, and the reinforcing member 100 is detachably mounted on the tray shell 200 to reinforce the area to be reinforced, thereby improving the compression and impact resistance of the tray shell 200.

[0048] For example, as shown in Figure 1 the four areas to be reinforced of the tray shell 200 are located at the corner positions, and the four reinforcing members 100 correspond to the four areas to be reinforced one by one. The reinforcing member 100 is detachably mounted on the tray shell 200 to reinforce the area to be reinforced.

[0049] The reinforcing member 100 and one of the areas to be reinforced are provided with a limiting recess 320, and the reinforcing member 100 and another of the areas to be reinforced are provided with a limiting boss 310; wherein the limiting boss 310 extends into the limiting recess 320, and the top of the limiting boss 310 is in contact with the bottom of the limiting recess 320.

[0050] It can be understood that the limiting boss 310 extends into the limiting recess 320, the top of the limiting boss 310 is in contact with the bottom of the limiting recess 320, forming a locally stacked double-layer material, supporting through the double-layer material, improving the compression and impact resistance of the tray shell 200, and through the design of local stacking, the packaging tray can be prepared using ultra-thin sheet material, effectively reducing the material cost of the packaging tray.

[0051] In actual execution, the limiting recess 320 can be arranged on the reinforcing member 100, and the limiting boss 310 can be arranged on the area to be reinforced of the tray shell 200. Alternatively, the limiting boss 310 can be arranged on the reinforcing member 100, and the limiting recess 320 can be arranged on the area to be reinforced of the tray shell 200.

[0052] For example, as shown in Figure 2As shown, the reinforcing member 100 is provided with a limiting boss 310 protruding downward, and the to-be-reinforced area of the tray shell 200 is provided with a limiting groove 320 with a groove opening facing downward.

[0053] In this embodiment, the reinforcing member 100 is folded over, as shown. Figure 3 As shown, the limiting boss 310 extends into the limiting groove 320, and the top of the limiting boss 310 is in contact with the bottom of the limiting groove 320, forming a locally stacked double-layer material, which is supported by the double-layer material, effectively improving the compression and impact resistance of the tray shell 200, and the appearance and thickness of the tray shell 200 are not affected, and the placement of the display panel is not affected.

[0054] In related technologies, external spacers, buffer covers and other materials are usually used to improve the buffer protection strength of the tray for the product. Such buffer materials are usually attached by workers, which is low in work efficiency and poor in attachment quality, and often causes residue or buffer material falling off. The attachment space of the buffer material at the corner position is small, and the attachment precision cannot be ensured, the carrying and buffer performance of the tray cannot be effectively improved, and the transportation safety of the display panel cannot be ensured.

[0055] In the embodiments of the present application, the to-be-reinforced area of the tray shell 200 is reinforced by the detachable reinforcing member 100. The reinforcing member 100 and the to-be-reinforced area are installed through the extending structure of the limiting boss 310 and the limiting groove 320, which is high in installation efficiency and reliability, and can be accurately installed at the corner position. By forming a locally stacked double-layer material, the carrying and buffer performance of the packaging tray is effectively improved, and the transportation safety of the display panel is ensured.

[0056] According to the packaging tray provided in the embodiments of the present application, the to-be-reinforced area of the tray shell 200 is provided with the reinforcing member 100, the limiting boss 310 extends into the limiting groove 320, and the top of the limiting boss 310 is in contact with the bottom of the limiting groove 320, forming a locally stacked double-layer material, which is supported by the double-layer material, thereby solving the problem of strength reduction caused by uneven thickness of the tray after plastic suction forming, effectively increasing the thickness of the local structure of the packaging tray, improving the carrying and buffer performance of the tray, ensuring the transportation safety of the display panel and other products, and the tray shell 200 and the reinforcing member 100 can use ultra-thin sheet materials, thereby saving the tray material cost.

[0057] In some embodiments, an end of the limiting boss 310 away from the top is provided with a first folding edge 311 extending outward, an end of the limiting groove 320 away from the bottom is provided with a second folding edge 321 extending outward, and the first folding edge 311 abuts against the second folding edge 321.

[0058] In this embodiment, the limiting boss 310 extends into the limiting groove 320, and the top of the limiting boss 310 contacts the bottom of the limiting groove 320, forming a partially stacked double-layer material. At the opening of the limiting groove 320, the first folded edge 311 abuts against the second folded edge 321, also forming a partially stacked double-layer material, ensuring the installation reliability of the reinforcement 100 and the tray housing 200.

[0059] For example, such as Figure 2 As shown, a limiting boss 310 is provided on the reinforcing member 100. The limiting boss 310 protrudes downward. The end of the limiting boss 310 away from the top is provided with two outwardly extending first folded edges 311. A limiting groove 320 is provided in the area to be reinforced of the pallet shell 200. The groove opening of the limiting groove 320 faces downward. The end of the limiting groove 320 away from the bottom is provided with two outwardly extending second folded edges 321.

[0060] In this embodiment, the folding reinforcement 100, such as Figure 3 As shown, the limiting boss 310 is inserted into the limiting groove 320, and the top of the limiting boss 310 contacts the bottom of the limiting groove 320. At the opening of the limiting groove 320, the first folded edge 311 abuts against the second folded edge 321, which effectively improves the compressive and impact resistance of the pallet shell 200.

[0061] In some embodiments, the first fold 311 is flip-connected to the second fold 321.

[0062] In this embodiment, the first folded edge 311 is flip-connected to the second folded edge 321, and the limiting boss 310 or the limiting groove 320 can rotate about the line connecting the first folded edge 311 and the second folded edge 321 as the axis.

[0063] For example, such as Figure 2 As shown, a limiting boss 310 is provided on the reinforcing member 100. The limiting boss 310 protrudes downward. The end of the limiting boss 310 away from the top is provided with two outwardly extending first folded edges 311. A limiting groove 320 is provided in the area to be reinforced of the pallet shell 200. The groove opening of the limiting groove 320 faces downward. The end of the limiting groove 320 away from the bottom is provided with two outwardly extending second folded edges 321.

[0064] In this embodiment, a first folded edge 311 is rotatably connected to a second folded edge 321, and the limiting boss 310 of the reinforcement 100 rotates about the line connecting the first folded edge 311 and the second folded edge 321 as an axis and extends into the limiting groove 320.

[0065] In this embodiment of the application, the reinforcement 100 can be at least one of the following structural forms:

[0066] Firstly, the reinforcing component 100 and the tray shell 200 are integrally formed.

[0067] In some embodiments, the tray housing 200 and at least one reinforcement member 100 are integrally formed, and the flipped portion where the first folded edge 311 and the second folded edge 321 are connected is provided with a pre-fold line 330.

[0068] In this embodiment, when designing the packaging pallet, corresponding reinforcement members 100 are designed at weak corners or other locations, and the pallet shell 200 and reinforcement members 100 are processed simultaneously through integrated molding.

[0069] like Figure 4 As shown, at the flipped part where the first folded edge 311 and the second folded edge 321 are connected, a pre-folded line 330 needs to be cut into a semi-broken line or a dotted line shape with a hot knife. This allows the reinforcement 100 to be flipped, and the limiting boss 310 extends into the limiting groove 320 to form a partially stacked double-layer material. The double-layer material provides support and improves the load-bearing and cushioning performance of the pallet.

[0070] It is understandable that the reinforcing member 100 and the pallet shell 200 are integrally molded, and both the reinforcing member 100 and the pallet shell 200 are made of plastic.

[0071] Secondly, the reinforcement component 100 is a separate structural component.

[0072] In some embodiments, the reinforcement 100 is a separate, detachable component.

[0073] like Figure 5 As shown, the four areas to be reinforced of the pallet housing 200 are located in the corners. The four reinforcing parts 100 are all independent detachable components. The reinforcing parts 100 are detachably installed on the pallet housing 200 and play a role in reinforcing the areas to be reinforced.

[0074] like Figure 6 As shown, for the reinforcement member 100 in the lower right corner, the limiting boss 310 is set on the reinforcement member 100, and the corresponding limiting groove 320 of the area to be reinforced faces downward.

[0075] In this embodiment, for the reinforcement members 100 at the other three corners, the limiting grooves 320 are provided on the reinforcement members 100, and the corresponding areas to be reinforced are provided with limiting bosses 310.

[0076] In practice, the independent reinforcement component 100 is universal and can be set as a standard part of the reinforcement component 100 used for packaging pallets of different sizes. When a reinforcement component 100 in the packaging pallet is damaged, it can be replaced by a reinforcement component 100 with the same processing standard.

[0077] It should be noted that whether the reinforcement 100 is integrally formed or has an independent structure, a snap-fit ​​structure can be set to ensure that the reinforcement 100 and the tray housing 200 snap tightly together, so that the reinforcement 100 is fixed to the tray housing 200 and does not fall off, thus ensuring the reliability of the installation of the reinforcement 100.

[0078] In some embodiments, the side of the first folded edge 311 facing the second folded edge 321 is provided with a first engaging portion, and the side of the second folded edge 321 facing the first folded edge 311 is provided with a second engaging portion that cooperates with the first engaging portion.

[0079] In this embodiment, a locking structure is provided on the first folded edge 311 and the second folded edge 321 to make the reinforcement 100 lock tightly with the tray housing 200, thus ensuring the reliability of the installation of the reinforcement 100.

[0080] It is understandable that the shapes of the limiting boss 310 and the limiting groove 320 are compatible. The limiting boss 310 is a cuboid, and the internal space of the limiting groove 320 also has a cuboid feature. The engaging structure is set on the first folded edge 311 and the second folded edge 321 of the extension. There is no need to change the structure of the limiting boss 310 and the limiting groove 320. This ensures the reliability of the installation of the reinforcement 100 while making installation and disassembly more convenient.

[0081] In some embodiments, the first engaging portion is an engaging protrusion 312 provided on the side of the first folded edge 311 facing the second folded edge 321, and the second engaging portion is a second groove 322 on the second folded edge 321 facing the first folded edge 311, with the engaging protrusion 312 extending into the second groove 322.

[0082] In this embodiment, the second groove 322 can be an elongated groove arranged along the length direction of the second fold 321, and the engaging protrusion 312 matches the shape of the second groove 322. The engaging protrusion 312 is an elongated protrusion arranged along the length direction of the first fold 311.

[0083] In actual implementation, the bottom of the second groove 322 can be set to be an arc-shaped bottom surface with a size larger than that at the groove opening. By interlocking the protrusion 312 and the second groove 322, the reinforcement 100 and the tray shell 200 can be tightly engaged.

[0084] For example, such as Figure 11 As shown, the limiting boss 310 is provided on the reinforcement member 100, and the first engaging part is provided with an upward-facing elongated engaging protrusion 312 on the first folded edge 311 of the reinforcement member 100.

[0085] like Figure 12 As shown, the area to be reinforced corresponding to the pallet shell 200 is located in the corner, such as... Figure 13As shown, the second engaging part of the area to be reinforced is a long strip-shaped second groove 322 with the groove opening facing downward on the second folded edge 321.

[0086] like Figure 14 As shown, when installing the reinforcement 100, the reinforcement 100 is installed from the back of the pallet housing 200. The limiting boss 310 extends into the limiting groove 320 to form a partially stacked double-layer material. The double-layer material provides support, and the engaging protrusion 312 extends into the second groove 322 to ensure that the reinforcement 100 and the pallet housing 200 are tightly engaged, so that the reinforcement 100 is fixed to the pallet housing 200 and does not fall off.

[0087] In some embodiments, the outer side wall of the limiting boss 310 is provided with a third engaging portion, and the inner side wall of the limiting groove 320 is provided with a fourth engaging portion that cooperates with the third engaging portion.

[0088] In this embodiment, a matching engagement structure is provided on the sidewalls of the limiting boss 310 and the limiting groove 320, so that the reinforcement 100 and the tray housing 200 are tightly engaged, ensuring the reliability of the installation of the reinforcement 100.

[0089] It is understandable that the limiting boss 310 extends into the limiting groove 320, forming a partially stacked double-layer material. The double-layer material provides support, and the side walls of the limiting boss 310 and the limiting groove 320 are provided with a mutually cooperating locking structure, which effectively ensures that the reinforcement 100 and the pallet shell 200 are tightly locked together, so that the reinforcement 100 is fixed to the pallet shell 200 and does not fall off.

[0090] In some embodiments, the third engaging portion is a first groove 313 on the outer sidewall of the limiting boss 310, the first groove 313 is provided with a first inclined surface 314, and the fourth engaging portion is a second boss 323 on the inner sidewall of the limiting groove 320, the second boss 323 is provided with a second inclined surface 324, the first groove 313 and the second boss 323 engage, and the first inclined surface 314 and the second inclined surface 324 contact each other.

[0091] In this embodiment, the first groove 313 and the second boss 323 engage, the first inclined surface 314 and the second inclined surface 324 contact each other, and the third engaging part and the fourth engaging part are provided on the side walls of the limiting boss 310 and the limiting groove 320 to cooperate with each other, so as to ensure the reliability of the installation of the reinforcement 100.

[0092] For example, such as Figure 7 As shown, the limiting boss 310 is provided on the reinforcement member 100, and the third engaging part is the first groove 313 on the outer side wall of the reinforcement member 100. The first groove 313 can be provided on all four outer side walls of the limiting boss 310, or only on two or three side walls.

[0093] like Figure 8As shown, the area to be reinforced corresponding to the pallet shell 200 is located in the corner, such as... Figure 9 As shown, the fourth engaging part of the area to be reinforced is a second protrusion 323 protruding inward from the inner sidewall. The shape, number and size of the second protrusion 323 and the first groove 313 are matched.

[0094] like Figure 10 As shown, when installing the reinforcement 100, it is installed from the back of the pallet housing 200. The limiting boss 310 extends into the limiting groove 320, forming a partially stacked double-layer material for support. The second boss 323 extends into the first groove 313, and the first inclined surface 314 and the second inclined surface 324 contact each other to ensure that the reinforcement 100 and the pallet housing 200 are tightly engaged, so that the reinforcement 100 is fixed to the pallet housing 200 and does not fall off.

[0095] The packaging pallet of this application introduces stackable reinforcement 100 into the packaging solution of display panels for the first time. This can significantly reduce the sheet thickness of the pallet, reduce packaging costs, solve the problem of strength reduction caused by uneven pallet thermoforming, enhance the thickness of local structures, improve the pallet's compression and impact resistance, and achieve standardization and structuring of the reinforcement 100.

[0096] Tests were conducted on both the integrally molded reinforcement 100 and the independent reinforcement 100. Both can be reinforced by stacking in corners and support areas when using ultra-thin sheets (thickness ≤ 0.7T) on the tray shell 200, meeting the requirements for drop, impact, and pressure resistance tests, and ensuring the safety of the display panel during transportation.

[0097] Simulations were conducted using ultra-thin sheet material one (0.6T) and ultra-thin sheet material two (0.5T). The simulation results show that the deformation of the pallet shell 200 using only ultra-thin sheet material one without reinforcement 100 is 3.6mm, and the maximum stress is 49.9MPa. The simulation results using ultra-thin sheet material two with reinforcement 100 show that the deformation of the pallet shell 200 is 2.4mm, and the maximum stress is 31.8MPa.

[0098] After reinforcement with the reinforcement member 100, the deformation of the pallet shell 200 is reduced by 33.3%, and the strength to resist external pressure is increased by 36.3%. The packaging pallet of this application embodiment can maintain better pressure resistance, impact resistance, and cushioning performance even with reduced sheet thickness.

[0099] This application embodiment also provides a packaging structure, including the packaging tray as described above, the packaging tray being used for packaging a display panel.

[0100] According to the packaging structure provided in the embodiments of this application, by equipping the area to be reinforced of the pallet shell 200 with a reinforcing member 100, the limiting boss 310 extends into the limiting groove 320 and the top of the limiting boss 310 contacts the bottom of the limiting groove 320, forming a partially stacked double-layer material. By supporting the double-layer material, the problem of strength reduction caused by uneven pallet thickness after vacuum forming can be solved. It effectively strengthens the thickness of the local structure of the packaging pallet, improves the load-bearing and cushioning performance of the pallet, and ensures the transportation safety of products such as display panels. In addition, the pallet shell 200 and the reinforcing member 100 can use ultra-thin sheets, saving pallet material costs.
