Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component packaging, in particular to a packaging protection piece and a packaging component of a photovoltaic component. Background Art

[0002] As users' requirements for the use of photovoltaic modules increase, the frames of photovoltaic modules are redesigned on the market, and the A-side structure of the long frame or short frame is removed to obtain a dust-proof photovoltaic module.

[0003] When this type of photovoltaic module is packaged, since the A side is removed from the long frame or the short frame, the use of conventional protective corner guards can easily form hollow gaps inside the corner guards, resulting in a lack of effective support between adjacent photovoltaic modules. The anti-dust modules are easily deformed and damaged during packaging. Utility Model Content

[0004] The utility model provides a packaging protection piece and a packaging component of a photovoltaic component, aiming to solve the problem that the dust-proof component is easily deformed and damaged during packaging.

[0005] An embodiment of the utility model provides a packaging protective member for a photovoltaic component, wherein the photovoltaic component comprises a first frame arranged along a first edge and a second frame arranged along a second edge, wherein along a thickness direction of the photovoltaic component, the first frame has a first height, the second frame has a second height, and a difference between the first height and the first height is Δh; the packaging protective member has a snap-fitting groove, wherein the snap-fitting groove is used for snap-fitting with the second frame, and a thickness of at least one side wall of the snap-fitting groove is t, and 0<t-Δh≤2mm.

[0006] When photovoltaic modules are stacked, if the difference between t-Δh is too small, the frames of two adjacent modules are close together, which may cause friction and collision during transportation, resulting in quality damage to the modules. If the difference between t-Δh is too large, it may cause waste of space inside the container, resulting in poor space utilization and increased transportation costs. Therefore, in the embodiment of the utility model, t-Δh is greater than zero, which can effectively prevent friction damage during module transportation. If t-Δh is less than or equal to 2 mm, higher utilization of container space can be achieved, which is conducive to reducing transportation costs.

[0008] Optionally, a bent hook is provided at one end of one of the first side wall and the second side wall away from the bottom of the engaging groove, and the bent hook is used to engage with the protruding portion of the second frame.

[0009] In the embodiment of the utility model, the design of the bent hook allows the packaging guard and the photovoltaic component to limit each other, which can ensure the installation reliability of the packaging guard and the photovoltaic component and help prevent them from falling off.

[0010] Optionally, the first side wall is perpendicular to the bottom wall, and the inner wall of the second side wall is inclined to intersect with the bottom wall at an acute angle.

[0011] In the embodiment of the utility model, the side wall of the packaging protection member is tilted so that the clamping groove is formed into a shape with a narrow opening and a wide bottom, so that the packaging protection member is firmly installed on the second frame portion and will not fall off naturally. The installation is also more convenient and labor-saving.

[0012] Optionally, an abutment surface is provided on the outer wall of the second side wall near the bottom of the clamping groove, and the abutment surface is perpendicular to the bottom wall.

[0013] In the embodiment of the utility model, the abutting surface of the packaging protection member can provide a larger contact area, forming a surface contact relationship with the back surface of another photovoltaic component, thereby ensuring that the packaging protection member is more stable after installation.

[0014] Optionally, the inner wall distance between the first side wall and the second side wall near the opening of the clamping slot is a1, and the inner wall distance between the first side wall and the second side wall near the bottom of the clamping slot is a2, and a1<a2.

[0015] In the embodiment of the utility model, when a1 is smaller than a2, the snap-in groove may be in a shape with a narrow opening and a wide bottom, so as to ensure that the packaging protection component is securely installed to the second frame portion and will not fall off naturally.

[0016] Optionally, the thickness of the bottom wall is s, s<t.

[0017] This packaging protective member with a thinner bottom wall can reduce the space occupied by the packaging protective member in the direction of the bottom wall thickness.

[0019] The corner guard includes two side sealing baffles arranged opposite to each other, and a bottom sealing baffle connected between the two side sealing baffles; the two side sealing baffles are connected to the bottom sealing baffle to form a snap-in groove, and the snap-in groove is used to accommodate the corner formed by the intersection of the first frame and the second frame; the gasket is fixed to the inner side or outer side of at least one of the side sealing baffles, and the gasket and the side sealing baffle together form the side wall.

[0020] Optionally, the gasket and the side sealing baffle are an integral structure.

[0021] In the embodiment of the utility model, the design of the gasket and the side sealing baffle as an integrated piece can save the subsequent process of bonding the isolated gasket to the side sealing baffle, which is beneficial to improving the packaging efficiency of the photovoltaic module.

[0022] An embodiment of the utility model further provides a packaging assembly, which includes any one of the aforementioned packaging protection components of the photovoltaic assembly.

[0023] Optionally, along the stacking direction of the plurality of photovoltaic modules, the packaging protection member is provided at the frame portion of each photovoltaic module.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] Reference Figures 1 to 10 An embodiment of the utility model provides a packaging protective member for a photovoltaic component, wherein the photovoltaic component 10 includes a first frame 101 arranged along a first edge and a second frame 102 arranged along a second edge, and along the thickness direction of the photovoltaic component 10, the first frame 101 has a first height, and the second frame 102 has a second height, and the difference between the first height and the first height is Δh; the packaging protective member 20 has a snap-fitting groove 201, and the snap-fitting groove 201 is used to snap-fit ​​with the second frame 102, and the thickness of at least one side wall of the snap-fitting groove 201 is t, 0<t-Δh≤2mm.

[0049] like Figure 1As shown, a schematic diagram of the structure of a photovoltaic module used in the packaging protection member of an embodiment of the utility model is shown. This photovoltaic module includes a first frame 101 arranged along the first side and a second frame 102 arranged along the second side. For a rectangular photovoltaic module, one of the first frame 101 and the second frame 102 is a long frame and the other is a short frame. For a photovoltaic module of a conventional structure, both the long frame and the short frame have an A surface, a B surface and a C surface, which are connected together to form a U-shaped groove, and the edge of the laminate is embedded in the U-shaped groove, wherein the A surface is located on the front of the photovoltaic module, the B surface is located on the side of the laminate, parallel to the thickness direction, and the C surface is located on the back of the photovoltaic module. In this photovoltaic module of the embodiment of the utility model, the A surface of the long frame or the short frame can be removed to obtain a photovoltaic module that can prevent dust accumulation.

[0050] Along the thickness direction of the photovoltaic assembly 10 , the first frame 101 has a first height, and the second frame 102 has a second height. Figure 1 The photovoltaic assembly of the illustrated embodiment of the present invention is to remove the A surface of the second frame 102 , so that the first height is greater than the second height, and a height difference Δh is formed between the two. Figure 2 A schematic diagram showing the photovoltaic modules stacked side by side is shown. Figure 2 As shown in the diagram, it can be seen that there is a large gap between adjacent photovoltaic modules at the location of the second frame 102. Due to the lack of an effective physical supporting structure in the gap area, the photovoltaic modules are easily deformed and damaged after being bundled and packaged.

[0051] Therefore, the embodiment of the utility model designs a method such as Figures 3 to 10 The packaging protection member 20 shown can be pre-assembled with the photovoltaic assembly 10 before the packaging and bundling of the photovoltaic assembly, so that the second frame 102 is embedded in the snap-in groove 201, and the snap-in groove 201 can be snap-fitted with the second frame 102, and the side wall of the snap-in groove 201 extends into the gap between two adjacent photovoltaic assemblies. In addition, based on the height difference Δh and the need to prevent friction damage between the first frame 101 of a photovoltaic assembly and the back plate of another photovoltaic assembly, the thickness of at least one side wall of the snap-in groove 201 is designed to be t, so that 0<t-Δh≤2mm, so that the thickness of the side wall of the snap-in groove 201 can ensure that a gap greater than 0 and not more than 2mm is formed between the first frame 101 of a photovoltaic assembly and the back plate of another photovoltaic assembly, and on the second side where the second frame 102 is located, the gap between adjacent photovoltaic assemblies can be fully filled and padded by the side wall of the snap-in groove 201 to play a supporting role.

[0052] Therefore, the packaging protection member of the embodiment of the utility model can be applied to the current novel anti-dust photovoltaic modules, and can be embedded in the gap between two adjacent photovoltaic modules when the photovoltaic modules are packaged. It can play a supporting role in the frame part without A surface, and play a barrier role in the frame part with A surface, which can improve the yield rate of photovoltaic modules during packaging and transportation. In addition, when the difference of t-Δh is too large, it is easy to cause waste of the internal space of the container, resulting in poor space utilization and increased transportation costs. Therefore, in the embodiment of the utility model, t-Δh is greater than zero, which can effectively prevent friction damage during the transportation of the components. When t-Δh is less than or equal to 2mm, higher utilization of the container space can be achieved, which is conducive to reducing transportation costs.

[0053] Optionally, refer to Figure 3 The packaging protective component 20 includes a bottom wall 20a and a first side wall 20b and a second side wall 20c connected on opposite sides of the bottom wall. The first side wall 20b, the bottom wall 20a and the second side wall 20c are connected to form the snap-in groove 201, and the thickness of the first side wall 20b and the second side wall 20c are both t.

[0054] Specifically, if Figure 3 As shown, in one embodiment, the packaging protection member 20 can be a U-shaped protection member, and the U-shaped protection member includes a bottom wall 20a, a first side wall 20b and a second side wall 20c. The first side wall 20b and the second side wall 20c are connected to both sides of the bottom wall 20a and are folded relative to the bottom wall 20a.

[0055] Intersecting therewith, thereby forming a snap-in groove 201 .

[0056] In this packaging protection member 20, the thickness of the first side wall 20b and the second side wall 20c can both be t, and when the photovoltaic modules 10 are packaged, they can be installed at intervals when multiple photovoltaic modules 10 are stacked side by side. For example, if 10 photovoltaic modules 10 are stacked side by side on a pallet, the packaging protection member 20 of the embodiment of the utility model can be installed on the photovoltaic modules 10 with odd or even serial numbers, thereby reducing the number of packaging protection members 20 and reducing packaging costs. Figure 4 and Figure 5 It also shows Figure 3 A three-dimensional schematic diagram of the assembly of the packaging protection member 20 and the photovoltaic module 10.

[0057] Optionally, refer to Figure 6 and Figure 7 A bent hook 202 is provided at one end of one of the first side wall 20b and the second side wall 20c away from the bottom of the engaging groove 201 , and the bent hook 202 is used to engage with the protruding portion of the second frame 102 .

[0058] Specifically, if Figure 6 and Figure 7 As shown, in one embodiment, a bent hook 202 is provided at one end of one of the first side wall 20b and the second side wall 20c away from the bottom of the clamping groove 201, and the bent hook 202 also has a U-shaped groove, the gap size of the groove is the same as the thickness of the protruding portion of the C surface of the second frame 102, and the protruding portion can be embedded in the groove of the bent hook 202. Thus, the packaging protection member 20 and the photovoltaic module 10 are mutually limited, which can ensure the installation reliability of the packaging protection member 20 and the photovoltaic module 10. Figure 8 and Fig. 9 It also shows Figure 6 A three-dimensional schematic diagram of the assembly of the packaging protection member 20 and the photovoltaic module 10.

[0059] Optionally, refer to Figure 7 The first side wall 20b is perpendicular to the bottom wall 20a, and the inner wall of the second side wall 20c is inclined to intersect with the bottom wall 20a at an acute angle.

[0060] Specifically, if Figure 7 As shown, in one embodiment, when the material of the packaging protection member 20 is a harder plastic, the first side wall 20b can be perpendicular to the bottom wall 20a, and the angle between the two is a right angle, so that the second side wall 20c is inclined relative to the bottom wall 20a, and the angle between the two is an acute angle. Thus, by using the inclination of one side wall, the clamping groove 201 is formed into a shape with a narrow opening and a wide bottom, ensuring that the packaging protection member 20 is sufficiently secure when installed on the second frame 102 and will not fall off naturally. It is also more convenient and labor-saving when installed.

[0061] Optionally, refer to Figure 7 A contact surface 203 is provided on the outer wall of the second side wall 20c near the bottom of the clamping groove 201, and the contact surface 203 is perpendicular to the bottom wall 20a.

[0062] Specifically, if Figure 7 As shown, in one embodiment, when the material of the packaging protection member 20 is a harder plastic, and when the inner wall of the second side wall 20c and the bottom wall 20a are inclined to intersect at an acute angle, in order to make the outer wall of the second side wall 20c fit more closely with the back of another photovoltaic module 10, the outer wall of the second side wall 20c is provided with a contact surface 203 near the bottom of the clamping groove 201, and the contact surface 203 is perpendicular to the bottom wall 20a. Therefore, the contact surface 203 can provide a larger contact area, form a surface contact relationship with the back of another photovoltaic module 10, and ensure that the packaging protection member 20 is more stable after installation.

[0063] Optionally, refer to Figure 3 or Figure 7The inner wall distance between the first side wall 20b and the second side wall 20c near the opening position of the snap-in slot 201 is a1, and the inner wall distance between the first side wall 20b and the second side wall 20c near the bottom position of the snap-in slot 201 is a2, and a1<a2.

[0064] Specifically, if Figure 3 As shown, in one embodiment, the first side wall 20b can be tilted relative to the bottom wall 20a, and the angle between the two is an acute angle, so that the second side wall 20c is tilted relative to the bottom wall 20a, and the angle between the two is an acute angle. Thus, the inner wall spacing between the first side wall 20b and the second side wall 20c near the opening position of the snap-in groove 201 is a smaller a1, and the inner wall spacing between the first side wall 20b and the second side wall 20c near the bottom position of the snap-in groove 201 is a larger a2. It should be noted that a2 can be the same as the height of the second frame 102, and a1 can be 1mm to 2mm smaller than a2. The snap-in groove 201 can be a shape with a narrow opening and a wide bottom to ensure that the packaging protective member 20 is sufficiently secure when installed on the second frame 102 and will not fall off naturally.

[0065] In addition, Figure 3 The packaging protection member 20 shown is similar to that for Figure 6 The packaging protection member 20 shown with the bent hook 202 may also be designed such that at least one of the first side wall 20b and the second side wall 20c is inclined relative to the bottom wall 20a. Figure 7 As shown, the inner wall spacing between the first side wall 20b and the second side wall 20c near the opening of the snap-in slot 201 is a smaller a1, and the inner wall spacing between the first side wall 20b and the second side wall 20c near the bottom of the snap-in slot 201 is a larger a2. It should be noted that a2 can be the same as the height of the second frame 102, and a1 can be 1mm to 2mm smaller than a2. The snap-in slot 201 can be a shape with a narrow opening and a wide bottom to ensure that the packaging protection member 20 is sufficiently secure when installed on the second frame 102 and will not fall off naturally.

[0066] Optionally, refer to Figure 7 , the thickness of the bottom wall 20a is s, s<t.

[0067] Specifically, if Figure 7 As shown, in one embodiment, when the material of the packaging protection member 20 is relatively rigid, for example, a plastic material can be used for injection molding. Figure 7 The packaging protection member 20 shown. At this time, the thickness of the bottom wall 20a can be designed to be s, and s<t, so that the space occupied by the packaging protection member 20 in the thickness direction of the bottom wall 20a can be reduced. It can be understood that similarly, for Figure 3 The illustrated packaging protection member 20 can also be designed such that the thickness of the bottom wall 20a is smaller than the thickness of the side walls.

[0068] When the packaging and protection member 20 is used to pack and box photovoltaic modules, more photovoltaic modules can be loaded into the container, which can improve the space utilization rate in the container and reduce logistics costs. For example, when the packaging and protection member 20 of the above embodiment is used to pack and box photovoltaic modules of a certain size, 18 pallets of modules can be loaded into a 40-cubic-meter cabinet with an internal length of 11980 mm and a width of 2350 mm, while when the embodiment of the utility model is used to pack photovoltaic modules of the same size, 20 pallets can be loaded.

[0069] Optionally, refer to Figures 10 to 15 , the packaging protection member 20 includes a corner protector 204 and a gasket 205;

[0070] The corner protector 204 includes two side sealing baffles 2041 arranged opposite to each other, and a bottom sealing baffle 2042 connected between the two side sealing baffles 2041; the two side sealing baffles 2041 are connected with the bottom sealing baffle 2042 to form a snap-in groove 201, and the snap-in groove 201 is used to accommodate the corner formed by the intersection of the first frame 101 and the second frame 102; the gasket 205 is fixed to the inner side or outer side of at least one of the side sealing baffles 2041, and the gasket 205 and the side sealing baffles 2041 together form the side wall.

[0071] Specifically, if Fig.10 As shown, in one embodiment, the packaging protection member 20 may include a corner protector 204 and a gasket 205. The corner protector 204 may be a three-dimensional protector formed by die-cutting, creasing, folding, and bonding a thin cardboard. Figures 11 to 15 The planar shapes of three different corner protectors 204 before being folded and bonded are shown respectively. The difference between them is that different numbers of gaskets 205 can be bonded and fixed inside or outside the side sealing baffle 2041 at different positions. Figures 11 to 15 After flipping and bonding, a corner protector 204 with a snap-in groove 201 can be obtained. This corner protector 204 can be set on the corner formed by the intersection of the first frame 101 and the second frame 102. Correspondingly, the gasket 205 is located on the inside or outside of the snap-in groove 201. At this time, the gasket 205 and the side sealing baffle 2041 jointly form a side wall, and the sum of the thicknesses of the two is the aforementioned t. The two are located between two adjacent photovoltaic modules, the side sealing baffle 2041 can contact one photovoltaic module, and the gasket 205 can contact another photovoltaic module, which can support and protect the packaging of the photovoltaic modules. Fig.16 It also shows Fig.10 A three-dimensional schematic diagram of the assembly of the packaging protection member 20 and the photovoltaic module 10.

[0072] Optionally, the gasket 205 and the side sealing baffle 2041 are an integral structure.

[0073] Specifically, in one embodiment, when cardboard or other materials are used to prepare the corner protector 204, the thickness of the surface at the location of the side sealing baffle 2041 can be increased, and the gasket 205 can be formed at one time, so that the gasket 205 and the side sealing baffle 2041 are naturally combined into one. Therefore, the subsequent process of bonding the isolated gasket 205 to the side sealing baffle 2041 can be omitted, which is conducive to improving the packaging efficiency of the photovoltaic module.

[0074] An embodiment of the utility model further provides a packaging assembly, which includes any one of the aforementioned packaging protection components of the photovoltaic assembly.

[0075] In addition, the embodiments of the utility model can use the above-mentioned packaging protective parts together with wooden pallets, wooden boxes and strapping belts as a set of packaging components for packaging and transporting whole pallets of photovoltaic modules, which can improve the protective performance of the packaging components for photovoltaic modules.

[0076] Optionally, refer to Fig.17 or Fig.18 Along the stacking direction of the plurality of photovoltaic modules 10, the packaging protection member 20 is disposed at the frame of each photovoltaic module 10.

[0077] Specifically, depending on the structural shape of the packaging guard 20 used, the packaging guard 20 provided in the above embodiment can be installed in the second frame 102 of the photovoltaic component 10, or in the corner where the first frame 101 and the second frame 102 of the photovoltaic component 10 intersect.

[0078] like Fig.17 As shown, in a plurality of photovoltaic modules 10 stacked and arranged, Figure 3 or Figure 6 The U-shaped packaging protection member 20 is shown as being stuck in the position of the second frame 102. Fig.17 As shown in the diagram, a packaging protection member 20 is arranged for each photovoltaic module 10, thereby reducing the number of packaging protection members 20 and reducing the packaging and transportation costs. In addition, in some embodiments, in order to make the packaging and transportation of photovoltaic modules more stable, packaging protection members 20 can also be installed on the second frame 102 of each photovoltaic module 10. In this case, the packaging protection members 20 can be arranged in a staggered manner on adjacent photovoltaic modules 10.

[0079] In addition, if Fig.18 As shown, in a plurality of photovoltaic modules 10 stacked and arranged, Fig.10The packaging protection member 20 in the illustrated corner protection shape is stuck at the corner position of the first frame 101 and the second frame 102. Fig.18 That is, the cross-sectional view of the corner-shaped packaging protection member 20 installed at this position. Fig.10 The packaging protection member 20 shown in the figure can fix the photovoltaic module and has a low packaging and transportation cost.

[0080] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
