Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to packaging boxes and photovoltaic products. Background Technology

[0002] Photovoltaic modules are the core and most important component of a solar power system. Traditional packaging of photovoltaic modules uses a barrel or box method. First, the modules are placed on pallets on a base plate, and then manually wrapped and secured internally. Next, the four-sided box and top cover are fitted over the modules for external wrapping and securing. When the modules arrive at the customer's location and are unpacked, the packaging must be removed in reverse order. This packaging method is not only time-consuming and labor-intensive but also inefficient, increasing labor costs and operational complexity.

[0003] To address this, some related technologies employ a three-sided box with one side open. The box is first fixed to a pallet, then the base plate and photovoltaic modules are placed on it, and then the sides and top are covered with covers for external binding and packaging. During the packaging process, the box is used to restrain the photovoltaic modules, which not only prevents the photovoltaic modules from tipping over but also eliminates the need for internal binding, thus improving packaging efficiency.

[0004] However, on automated packaging lines, pallets need to be moved between workstations. Since one side of the box is open, there is a risk that the photovoltaic modules may slip and shift due to vibration during handling. Utility Model Content

[0005] In view of this, the present invention provides a packaging box and photovoltaic products to solve the problem that photovoltaic modules are prone to tipping over and shifting during the packaging process.

[0006] In a first aspect, the present invention provides a packaging box, comprising a pallet, a box body, a bottom plate, and a fastener. The box body is disposed on the pallet. The box body includes multiple side panels and multiple skirt panels. The multiple side panels are connected sequentially by their sides. The first side panel and the last side panel are spaced apart to enclose a packaging area with an opening on the side. The skirt panels are connected to at least the first and last side panels. The skirt panels are located at the end of the side panels closest to the pallet and within the packaging area. The bottom plate is disposed on the skirt panels. The fastener passes through the bottom plate and the skirt panels and connects to the pallet to fix the bottom plate and the side panels to the pallet.

[0007] Beneficial effects: During packaging, the box is first placed on a pallet, then the base plate is placed at the bottom of the packaging area. The box and base plate are then secured with fasteners before the photovoltaic modules are placed into the packaging area. Because the box is secured with fasteners, the side panels can support the photovoltaic modules from the side, preventing them from tipping over. Since the base plate is also secured with fasteners, its position is less likely to shift during pallet handling, thus reducing the risk of the photovoltaic modules shifting. Therefore, the packaging box helps prevent the photovoltaic modules from tipping over and shifting during the packaging process.

[0008] In one alternative embodiment, the surface roughness of the base plate is greater than the surface roughness of the housing.

[0009] Beneficial effects: By selecting a base plate with a relatively larger surface roughness, the friction between the base plate and the photovoltaic module can be increased, which can prevent the photovoltaic module from sliding relative to the base plate and further reduce the risk of the photovoltaic module shifting during the packaging process.

[0010] In one alternative embodiment, the fastener includes a limiting portion and a connecting portion, the limiting portion being located on the side of the base plate opposite to the skirt plate, and the connecting portion connecting the limiting portion and the tray.

[0011] Beneficial effects: The connecting part is connected between the limiting part and the pallet, thereby applying a force to the limiting part in the direction of the pallet, so that the limiting part presses against the bottom plate and the skirt from the side of the bottom plate away from the skirt, thus fixing the box and the bottom plate.

[0012] In one alternative embodiment, the fastener includes a plurality of connecting portions, wherein two of the connecting portions are respectively connected to both ends of the limiting portion.

[0013] Beneficial effects: Multiple connecting parts can more firmly fix the fastener, and the two connecting parts respectively limit the two ends of the limiting part, which can prevent the edge of the limiting part from lifting up and reduce the risk of the fastener scratching the photovoltaic module.

[0014] In one alternative embodiment, the top surface of the limiting portion is flush with or lower than the top surface of the base plate.

[0015] Beneficial effects: By ensuring that the limiting part is not higher than the top surface of the base plate, it is possible to prevent the limiting part from contacting the photovoltaic module, thereby further reducing the risk of the fastener scratching the photovoltaic module.

[0016] In one alternative implementation, the fastener is a nail.

[0017] Beneficial effects: The base plate and skirt plate are fixed to the pallet with nails, forming a rigid connection between the nails and the pallet, which is not easy to loosen. The overall structure is more stable during handling. In addition, the tools and methods for fixing the nails are relatively simple and convenient, and the cost is also relatively low, which helps to reduce the manufacturing and assembly costs of the packaging box.

[0018] In one optional embodiment, the enclosure includes a first enclosure and two second enclosures, the two second enclosures being respectively connected to both ends of the first enclosure, the second enclosures being parallel to each other, and the connecting lines of the first enclosure and the second enclosures being parallel to each other.

[0019] Beneficial effects: The enclosure features a first panel and two second panels, which fold to form a square packaging area suitable for placing standard-sized photovoltaic modules.

[0020] In one alternative embodiment, a first cover plate and a second cover plate are further included, the first cover plate being used to close the side of the packaging area and the second cover plate being used to close the top surface of the packaging area.

[0021] Beneficial effect: After placing the photovoltaic modules, use the first cover plate to cover the sides and the second cover plate to cover the top, so that the packaging box completely covers the photovoltaic modules, so that they can be tightened and fixed later.

[0022] Secondly, this utility model also provides a photovoltaic product, including a photovoltaic module and a packaging box provided by this utility model, wherein the photovoltaic module is disposed inside the packaging box.

[0023] Beneficial effects: The photovoltaic products include the packaging box provided by this utility model, and therefore have the corresponding beneficial effects brought by the packaging box, which will not be elaborated here.

[0024] In one alternative embodiment, the photovoltaic product further includes packing straps for securing the packaging box.

[0025] Beneficial effects: Using packing straps to tighten and secure the packaging box from the outside ensures that the various parts of the packaging box are firmly connected together, preventing the photovoltaic products from falling apart during transportation. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0037] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this application, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection via an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "end," "length," "inner," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0039] In related technologies, multiple photovoltaic modules are generally packaged in a horizontal stacking manner, that is, the thickness direction of the photovoltaic modules is along the horizontal direction, so as to prevent the bottom photovoltaic module from being crushed due to excessive pressure when stacked vertically. However, in this case, the photovoltaic modules are prone to tilting to the side.

[0040] To constrain photovoltaic modules and simplify the packaging process, a three-sided box with one open side is generally used. The box is first fixed on the pallet, then the bottom plate and photovoltaic modules are placed on it, and then the side and top covers are closed for external wrapping and packing. During the packaging process, the box is used to constrain the photovoltaic modules, which not only prevents the photovoltaic modules from tipping over but also eliminates the need for internal wrapping and tightening, thus improving packaging efficiency.

[0041] On automated packaging lines, packaging needs to be done at multiple workstations. Therefore, it is necessary to move pallets containing semi-finished product boxes and photovoltaic modules. Since one side of the box is open, the bottom plate is prone to shifting towards the open side due to vibration during the handling process, which affects the packaging process.

[0042] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0043] Reference Figure 1 , Figure 2 , Figure 3 According to an embodiment of the present invention, a packaging box is provided, including a box body 1, a bottom plate 2, and a fixing member 3. The box body 1 is used to place on a pallet 6. The box body 1 includes multiple side panels 101 and multiple skirt panels 102. The multiple side panels 101 are connected sequentially through the sides. The first side panel 101 and the last side panel 101 are spaced apart to enclose a packaging area with an opening on the side. The skirt panels 102 are connected to at least the first side panel 101 and the last side panel 101. The skirt panels 102 are located at the end of the side panels 101 near the pallet 6 and are located within the packaging area. The bottom plate 2 is used to be placed on the skirt panels 102. The fixing member 3 is used to pass through the bottom plate 2 and the skirt panels 102 and connect to the pallet 6 to fix the bottom plate 2 and the side panels 101 on the pallet 6.

[0044] The side refers to the edge located on the side of the enclosure 101. During packaging, the box 1 is first placed on the tray 6, and then the bottom plate 2 is placed at the bottom of the packaging area. The positions of the box 1 and the bottom plate 2 are fixed with the fasteners 3, and then the photovoltaic modules 7 are placed into the packaging area.

[0045] Because the box 1 is fixed by the fastener 3, the side panel 101 can support the photovoltaic module 7 from the side, preventing the photovoltaic module 7 from tipping over. Since the bottom plate 2 is also fixed by the fastener 3, the position of the bottom plate 2 is not easy to shift during the handling of the pallet 6, thereby reducing the risk of the photovoltaic module 7 supported on the bottom plate 2 shifting. Therefore, the packaging box helps to prevent the photovoltaic module 7 from tipping over and shifting during the packaging process.

[0046] It is understood that in this utility model, the packaging box can be a cardboard box, a wooden box, or other materials. When the packaging box is a cardboard box, the side panels 101 and the skirt panels 102 can be folded and connected to each other. When the packaging box is a wooden box, the side panels 101 and the skirt panels 102 are pre-connected and fixed together by connectors.

[0047] When using the packaging box of this utility model to package photovoltaic modules 7, the packaging box is usually a cardboard box. At this time, the packaging steps can be carried out at different workstations. For example, the box body 1 and the bottom plate 2 are folded, placed and fixed at the first workstation, the photovoltaic modules 7 are placed at the second workstation, and the photovoltaic modules 7 are further packaged at the third workstation. This is suitable for building an automated packaging production line and improving the factory space utilization and flexibility.

[0048] In addition to photovoltaic module 7, the packaging box of this utility model is also suitable for packaging other items, and can also prevent items from tipping over and shifting during the packaging process. This utility model does not limit the scope of application of the packaging box.

[0049] exist Figure 1 In the illustrated embodiment, the size of the box 1 is the same as that of the tray 6, and one box 1 corresponds to one tray 6. In other embodiments not shown, multiple boxes 1 can also be placed horizontally on one tray 6, and each box 1 is fixed by the fastener 3 and the tray 6 respectively. This utility model does not limit this.

[0050] In some embodiments, the surface roughness of the base plate 2 is greater than that of the housing 1. By selecting the base plate 2 with a relatively larger surface roughness, the frictional force generated between the base plate 2 and the photovoltaic module 7 can be increased, preventing the photovoltaic module 7 from sliding relative to the base plate 2 and further reducing the risk of the photovoltaic module 7 shifting during the packaging process.

[0051] For example, in some embodiments, the packaging box is a cardboard box. Since the bottom plate 2 is hidden inside after packaging, the face paper of the bottom plate 2 can be selected as kraft paper with a relatively rougher surface that does not require printing patterns. Since the box body 1 is exposed on the outside after packaging, the face paper of the side panel 101 can be selected as other types of paper with a relatively smoother surface that are suitable for printing patterns, thereby taking into account both the reliability during packaging and the aesthetics after packaging.

[0052] In some embodiments, the fastener 3 includes a limiting part and a connecting part. The limiting part is located on the side of the base plate 2 away from the skirt plate 102, and the connecting part is connected between the limiting part and the tray 6. The connecting part is connected between the limiting part and the tray 6, thereby applying a force to the limiting part toward the tray 6, so that the limiting part presses against the base plate 2 and the skirt plate 102 from the side of the base plate 2 away from the skirt plate 102, thereby fixing the box 1 and the base plate 2.

[0053] In some embodiments, the fastener 3 includes multiple connecting portions, with two connecting portions respectively connected to both ends of the limiting portion. Multiple connecting portions provide a more secure fixation of the fastener 3, and the two connecting portions respectively limit both ends of the limiting portion, preventing the edges of the limiting portion from lifting and reducing the risk of the fastener 3 scratching the photovoltaic module 7.

[0054] Meanwhile, in some embodiments, the top surface of the limiting part can be flush with or lower than the top surface of the base plate 2. By ensuring that the limiting part is not higher than the top surface of the base plate 2, it is possible to prevent the limiting part from contacting the photovoltaic module 7, thereby further reducing the risk of the fixing member 3 scratching the photovoltaic module 7.

[0055] Specifically, in some embodiments, the material of the base plate 2 is corrugated paper, and a fastener 3 with a height of the limiting part less than the thickness of the corrugated paper is selected. When fixing, the limiting part presses against the base plate 2 and causes the base plate 2 around the limiting part to sink and deform (not shown in the figure), thereby ensuring that the limiting part is not higher than the top surface of the base plate 2.

[0056] Understandably, the fastener 3 can have various options; in some embodiments, the fastener 3 is a nail. The base plate 2 and the skirt plate 102 are fixed to the pallet 6 by nails, forming a rigid connection between the nails and the pallet 6, which is less prone to loosening and makes the overall structure more stable during handling. Furthermore, the tools and methods for using nails are relatively simple and convenient; only a nail gun is needed to easily complete the fixing operation. The fixing position is also quite flexible, suitable for both manual operation and automated robotic operation, enabling further automation of the packaging line. Nails are also relatively inexpensive, helping to reduce the manufacturing and assembly costs of the packaging boxes.

[0057] For example, refer to Figure 1 and Figure 3 The fastener 3 can be a U-shaped nail. Furthermore, in some embodiments, the fastener 3 can be a U-shaped galvanized steel nail. The U-shaped galvanized steel nail can ensure a certain degree of rust prevention and connection strength, and at the same time, the cost is relatively low, which helps to reduce the manufacturing and assembly costs of the packaging box.

[0058] Of course, besides nails, other suitable standard parts can be used as fasteners 3, such as a locking mechanism. However, the cost of a locking mechanism is relatively high, and mounting holes need to be pre-drilled on the tray 6, base plate 2, and skirt plate 102, making operation less convenient. Other usable fasteners 3 can be found in relevant technologies and will not be elaborated here.

[0059] In some embodiments, refer to Figure 1 The enclosure 101 includes a first enclosure and two second enclosures, with the two second enclosures connected to the two ends of the first enclosure respectively. The second enclosures are parallel to each other, and the connecting lines between the first enclosures and the second enclosures are parallel to each other. The box 1 adopts a design with one first enclosure and two second enclosures, which forms a square packaging area after folding, suitable for placing standard-sized photovoltaic modules 7.

[0060] In some embodiments, refer to Figure 4 and Figure 5 The packaging box also includes a first cover plate 4 and a second cover plate 5. The first cover plate 4 is used to close the sides of the packaging area, and the second cover plate 5 is used to close the top surface of the packaging area. After the photovoltaic module 7 is placed, the first cover plate 4 is used to cover the sides of the photovoltaic module 7, and the second cover plate 5 is used to cover the top surface of the photovoltaic module 7, so that the packaging box completely covers the photovoltaic module 7 for subsequent tightening and fixing.

[0061] Understandably, in Figure 4 and Figure 5 In the illustrated embodiment, the first cover plate 4 and the second cover plate 5 are independent of each other. In other embodiments, the first cover plate 4 and the second cover plate 5 may also adopt other connection methods, and this utility model does not limit them.

[0062] For example, in some embodiments not shown, the first cover plate 4 and the second cover plate 5 are foldably connected together, which facilitates covering the photovoltaic module 7 together with the first cover plate 4 and the second cover plate 5 during packaging, simplifying the operation process.

[0063] For example, in some embodiments not shown, the second cover plate 5 can be foldably connected to the end of the enclosure 101 away from the skirt 102. After the photovoltaic module 7 is placed, the second cover plate 5 can be folded directly to cover the photovoltaic module 7, without having to retrieve the second cover plate 5, thus simplifying the operation process.

[0064] Secondly, this utility model also provides a photovoltaic product, including a photovoltaic module 7 and a packaging box provided by this utility model, wherein the photovoltaic module 7 is disposed inside the packaging box.

[0065] The photovoltaic products include the packaging box provided by this utility model, and therefore have the beneficial effects brought by the packaging box, which will not be elaborated here.

[0066] In some embodiments, refer to Figure 6 The photovoltaic products also include packing straps 8, used to secure the packaging box. Using the packing straps 8 to secure the packaging box from the outside ensures that the various structural parts of the packaging box are firmly joined together, preventing the photovoltaic products from falling apart during transportation.

[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
