[0002] Silicon crystal square rods are single crystal silicon rods grown from polysilicon raw materials by the direct pulling single crystal method, and are processed by the preliminary slicing process. When the silicon crystal square rods are further processed, they need to be packaged and transported. The existing packaging and transportation method is generally to use foam boxes for packaging and then package and transport them through cartons. Since foam boxes and cartons are easy to damage, they are lost during transportation and unpacking, and the reuse rate is low. Moreover, when packaging through foam boxes, each silicon crystal square rod needs to be packaged independently, which is not convenient, resulting in low packaging efficiency. Summary of the invention

[0003] In view of this, it is necessary to provide a packaging material that is convenient for packaging silicon crystal square rods, so as to solve the technical problems of large packaging material loss and low packaging efficiency existing in the prior art.

Enclosures for limiting the movement of the silicon crystal square bars are arranged on the four edges of the end faces of the bottom tray, the middle partition and the top protective plate that are in contact with the silicon crystal square bars.

[0005] Preferably, protective sleeves are respectively sandwiched between the bottom support plate and the middle partition plate, between the middle partition plates and between the middle partition plates and the top protective plate, and the protective sleeves are vertically penetrated with a plurality of receiving grooves for housing the silicon crystal square rods. The receiving grooves are evenly arranged and matched with the external dimensions of the silicon crystal square rods, and the outer side walls of the protective sleeves are aligned with the outer side walls of the bottom support plate.

[0006] Preferably, the height of the protective sleeve is a preset height.

[0007] Preferably, each receiving groove of the protective sleeve has chamfers around its upper and lower edges.

[0008] Preferably, a guard plate is provided in an annular manner around the outer side walls of the protective sleeve.

[0009] Preferably, protective layers are provided on the end surfaces of the bottom support plate, the middle separator plate and the top protective plate that are in contact with the silicon crystal square rod.

[0010] Preferably, a protective layer is also provided on the inner end surfaces of the enclosures of the bottom support plate, the middle partition plate and the top protective plate.

[0011] Preferably, corner guards are respectively provided on the outer sides of the four corners of the top layer guard plate, and the upper ends of the corner guards are foldably connected to the four corners of the top layer guard plate, and the lower ends of the corner guards extend vertically downward along the four corners of the top layer guard plate and contact the outer sides of the four corners of the bottom layer support plate, forming enclosures between the four corners of the top layer guard plate and the four corners of the bottom layer support plate to protect the four corners of each middle layer partition.

[0012] It can be seen from the above technical scheme that the packaging material provided by the present application is convenient for packaging silicon crystal square rods, including a bottom tray fixedly arranged on the upper end of the bottom tray, a plurality of middle partitions and a top protective plate stacked from bottom to top on the bottom tray, and enclosures for limiting the movement of the silicon crystal square rods are arranged on the four edges of the end faces where the bottom tray, the middle partitions and the top protective plate are in contact with the silicon crystal square rods.

[0024] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0025] Please see Figure 1 , Figure 2 and Figure 8The embodiment of the present invention provides a packaging material for packaging silicon crystal square rods, including a bottom tray 10 arranged in parallel, a bottom tray 20 fixedly arranged on the upper end of the bottom tray 10, and a plurality of middle partitions 30 and a top protective plate 40 stacked from bottom to top on the bottom tray 20. The bottom tray 10 adopts a pallet structure, which can be convenient for forklift transportation. The bottom tray 20 is arranged in parallel on the upper end surface of the bottom tray 10. The bottom tray 20 and the bottom tray 10 are fixedly arranged. The silicon crystal square rods are stacked between the bottom tray 20 and the middle partition 30, between the middle partition 30 and the middle partition 30, and between the middle partition 30 and the top protective plate 40. The edges of the end surfaces of the bottom tray 20, the middle partition 30 and the top protective plate 40 that are in contact with the silicon crystal square rods are all provided with enclosures 50 for limiting the movement of the silicon crystal square rods. When packing silicon crystal square rods, the silicon crystal square rods are stacked from bottom to top on the upper end of the bottom support plate 20, the middle partition plate 30 is sandwiched between each layer of silicon crystal square rods, and the top protective plate 40 is buckled on the upper end of the silicon crystal square rods stacked on the top layer to form protection. During the stacking process of the silicon crystal square rods, each layer is evenly stacked along the loading surface of the bottom support plate 20 and the middle partition plate 30, and a diaphragm is sandwiched between two adjacent silicon crystal square rods for protection. The enclosure 50 around the bottom support plate 20 is used to protect the silicon crystal square rods stacked on the bottom layer. The lower edge of the outer periphery of the crystal rod is limited, and the upper edge of the outer periphery of the silicon crystal rod stacked on the top layer is limited by the enclosure 50 around the top layer protective plate 40, and the upper and lower end faces of the middle layer partition 30 sandwiched between each layer of silicon crystal rods are provided with enclosures 50 on all sides. While the middle layer partition 30 is used to isolate and protect each layer of silicon crystal rods, the enclosures 50 around the middle layer partition 30 are used to limit the four sides of the silicon crystal rods of the upper and lower layers at the same time, so as to limit the movement of the silicon crystal rods.

[0026] Please see Figures 3 to 7In order to make packaging more convenient, protective sleeves 60 matching the packaged silicon crystal square rods are respectively sandwiched between the bottom tray 20 and the middle partition 30, between the middle partition 30 and the middle partition 30, and between the middle partition 30 and the top protective plate 40. The protective sleeves 60 are vertically penetrated with a plurality of receiving grooves 61 for sleeved silicon crystal square rods. The receiving grooves 61 are evenly arranged and matched with the outer dimensions of the silicon crystal square rods. The height of the protective sleeve 60 matches the height between each layer, and the outer side walls of the protective sleeve 60 are aligned with the outer side walls of the bottom tray 20. When packaging silicon crystal square rods, the protective cover 60 can be placed on the upper end of the bottom support plate 20 first, and the silicon crystal square rods to be packaged can be inserted into each receiving groove 61 in the protective cover 60 in turn. Then, the middle partition plate 30 is buckled on the upper end of the silicon crystal square rods stacked in this layer, and then another protective cover 60 is placed on the upper end of the middle partition plate 30. In this way, stacking is performed. The protective cover 60 can fully surround and protect the silicon crystal square rods stacked in each layer to prevent contact between the silicon crystal square rods. The outer side walls of the protective cover 60 are aligned with the outer side walls of the bottom support plate 20, so as to shield and protect the periphery of the silicon crystal square rods stacked in each layer. The protective cover 60 also plays an auxiliary limiting role to prevent the silicon crystal square rods from moving.

[0027] The bottom tray 20, the middle partition 30 and the top protective plate 40 are all made of wood or high-strength plastic, which are strong and not easy to be damaged. The surfaces of the bottom tray 20, the middle partition 30 and the top protective plate 40 in contact with the silicon crystal square rods are all flat, which can facilitate the packaging of silicon crystal square rods of the same size and specifications, and has strong applicability. The protective cover 60 is a prefabricated part made of polyethylene foam. The receiving groove 61 on the protective cover 60 matches the outer dimensions of the packaged silicon crystal square rods, and its height is a preset height, which matches the height between each layer. In the actual packaging operation process, the bottom tray 20, the middle partition 30 and the top protective plate 40 are universal parts and can be reused. The protective cover 60 can be replaced according to the outer dimensions of the packaged silicon crystal square rods, and can also be reused. In this way, while improving the packaging efficiency, the loss of packaging materials can also be reduced.

[0028] Furthermore, each receiving groove 61 of the protective sleeve 60 has chamfers around its upper and lower edges, making it easier to place the silicon crystal square rod into the receiving groove 61. In addition, in order to improve the protective strength of the protective sleeve 60, a protective plate 62 is provided around the outer wall of the protective sleeve 60 in a circular manner. The protective plate 62 is made of a wooden board or a plastic board, which can strengthen the support of the protective sleeve 60 and improve the protection of the outer periphery of the silicon crystal square rod.

[0029] Furthermore, a protective layer is laid on the end surfaces of the bottom support plate 20, the middle partition plate 30 and the top protective plate 40 that are in contact with the silicon crystal square rod, and a protective layer is also laid on the inner end surface of the enclosure 50 of the bottom support plate 20, the middle partition plate 30 and the top protective plate 40. The protective layer is made of high-strength fiber cloth or nylon cloth, has the function of energy absorption and anti-slip, and can improve the protection of the silicon crystal square rod.

[0030] Please see Fig. 9 and Fig.10 The four corners of the top guard plate 40 are connected to the four corners of the bottom support plate 20, and the lower ends of the corner guards 70 extend vertically downward along the four corners of the top guard plate 40 and contact the four corners of the bottom support plate 20. The four corners of the top guard plate 40 and the four corners of the bottom support plate 20 form a fence 50 between the four corners of the top guard plate 40 and the four corners of the bottom support plate 20 to protect the four corners of each middle partition 30. The corner guard 70 is connected or hinged to the four corners of the top guard plate 40 by ropes. When storing, it can be swung to one side of the top guard plate 40, which occupies less space and is convenient for storage. The length of the corner guard 70 matches the height of the packaging. When packaging, the corner guard 70 hangs down at the four corners of the top guard plate 40 and can extend along the four corners of the top guard plate 40 to the four corners of the bottom support plate 20 to form a longitudinal fence 50, so as to facilitate the packaging and fixing of the corner guard 70 and the top guard plate 40 by the packaging belt, thereby improving the packaging efficiency.

[0031] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
