[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0036] Example 1
[0037] A photovoltaic module corner protector, see Figure 1 , including a bottom guard plate 2, a first edging plate 3, a second edging plate 4 and a corner side guard plate 5. The bottom guard plate 2 has a first side and a second side that match the edge of the photovoltaic module frame, wherein the first side is perpendicular to the second side.
[0038] See also Figures 1-4 One end of the first edging plate 3 is connected to the first side of the bottom guard plate 2, and the other end of the first edging plate 3 is bent upward to form a vertically arranged first side guard plate 31. The free end of the first side guard plate 31 is bent horizontally inward to form a horizontally arranged first top guard plate 32. The free end of the first top guard plate 32 is bent toward the space between the first side guard plate 31 and the first top guard plate 32 to form a first fixed plate 33. One end of the second edging plate 4 is connected to the second side of the bottom guard plate 2, and the other end of the second edging plate 4 is bent upward to form a vertically arranged second side guard plate 41, and the free end of the second side guard plate 41 is bent horizontally inward to form a horizontally arranged second top guard plate 42, and the free end of the second top guard plate 42 is bent toward the space between the second side guard plate 41 and the second top guard plate 42 to form a second fixed plate 43; one end of the corner side guard plate 5 is connected to the side of the second side guard plate 41 close to the first edging plate 3, and the other end is bent to the inner side of the first side guard plate 31. After folding, the bottom guard plate 2, the first side guard plate 31, the second side guard plate 41, the first top guard plate 32 and the second top guard plate 42 form a cavity that can accommodate the corners of the photovoltaic module frame.
[0039] When wrapping the corners of the photovoltaic module, the bottom surface of the frame is the A side, the two adjacent side surfaces of the frame are the B side and the C side respectively, the top surface of the frame connected to the B side is the D side, and the top surface connected to the C side is the F side. First, the bottom guard plate 2 is set opposite to the A side of the frame, and then the second edging plate 4 is continuously bent, and the B side and D side of the frame are wrapped by the second side guard plate 41 and the second top guard plate 42. Then, the second edging plate 4 is fixed to the frame by the second fixing plate 43, so that the second side guard plate 41 and the second top guard plate 42 can tightly wrap the B side and D side of the frame; as for the corner side guard plate 5, it is bent toward the C side of the frame until it is close to the side, thereby wrapping the C side of the frame. Next, the first edging plate 3 is continuously bent, the corner side guard plate 5 is pressed against the first side guard plate 31, the E side of the frame is wrapped against the first top guard plate 32, and the first edging plate 3 is fixed to the frame against the first fixing plate 33, so that the first side guard plate 31 and the first top guard plate 32 can tightly wrap the C and E sides of the frame. By providing the corner side guard plate 5 on the second side guard plate 41, when wrapping the frame, the second side guard plate 41 and the corner side guard plate 5 can wrap the corners of the frame, preventing the corners of the frame from being exposed through the gap between the first side guard plate 31 and the second side guard plate 41, which could cause scratches on staff and damage other photovoltaic modules. After being bent, the corner side guard plate 5 is located on the inner side of the first side guard plate 31 and is pressed against it by the first side guard plate 31. This prevents the corner side guard plate 5 from becoming loose or falling, while further improving the structural reliability of the second edging plate 4.
[0040] In this embodiment, the length of the corner side guard plate 5 is greater than the distance from the first side guard plate 31 to the second side, so that the corner guard plate can be pressed tightly by the first side guard plate 31 to prevent it from loosening or falling. Preferably, the length of the corner side guard plate 5 is equal to the maximum distance from the first side guard plate 31 to the second side.
[0041] In this embodiment, see Figure 1-Figure 2 The top and bottom of the corner side guard plate 5 are respectively provided with an inward-bent corner top guard plate 6 and a corner bottom guard plate 7. During the packaging process, the corner top guard plate 6 and the corner bottom guard plate 7 are respectively bent to the A side and E side of the frame. In this way, the top and bottom of the corners of the frame can be wrapped, further improving the protection effect.
[0042] In this embodiment, see Figure 1-Figure 2 The second top guard plate 42 is L-shaped and includes a top guard plate body 421 and a pressing tongue 422. The ends of the top guard plate body 421 are respectively connected to the second side guard plate 41 and the second fixing plate 43. The free end of the pressing tongue 422 is located below the first top guard plate 32. During the packaging process, after the second top guard plate 42 wraps around the D surface of the frame, the pressing tongue 422 covers the E surface of the frame. When the first top guard plate 32 is bent to the top of the E surface of the frame, it can press the pressing tongue 422, which can further fix the second top guard plate 42, improve structural reliability, and prevent looseness.
[0043] In this embodiment, see Figure 1 、 Figure 4 The first fixing plate 33 and the second fixing plate 43 have the same structure. Taking the first fixing plate 33 as an example, one end of the first fixing plate 33 is connected to the first top guard plate 32, and the other end is bent downward to form a vertically arranged first inner guard plate 331. The free end of the first inner guard plate 331 is bent horizontally inward to form a horizontally arranged second inner guard plate 332, and the second inner guard plate 332 is bent downward to form a vertically arranged third inner guard plate 333. The second inner guard plate 332 and the third inner guard plate 333 are tightly attached to the groove on the inner side of the frame (the groove is originally used to fix the photovoltaic module to the frame) and are thus clamped in the groove, thereby fixing the corner guard to the frame. Similarly, the second fixing plate 43 is also formed with the corresponding first inner guard plate 331, second inner guard plate 332 and third inner guard plate 333, and is fixed to the frame by the second inner guard plate 332 and the third inner guard plate 333.
[0044] In this embodiment, part of the folded edge of the corner guard is in direct contact with the edge of the frame, such as between the bottom guard plate 2 and the first side guard plate 31 and the second side guard plate 41, between the second side guard plate 41 and the second top guard plate 42, and between the corner side guard plate 5 and the corner top guard plate 6 and the corner bottom guard plate 7. In order to protect these locations from being scratched by the edge of the frame, the fold lines at these locations are press lines. The actual size of the three inner guard plates of the first fixed plate 33 and the second fixed plate 43 is small, making folding difficult. To facilitate folding, the fold line between the second inner guard plate 332 and the first inner guard plate 331 and the third inner guard plate 333 adopts a serrated line. To ensure the strength of the fixed plate after folding, the serrated line is a sparse serrated line. As for the fold line between the first side guard plate 31 and the second side guard plate 41, since this location does not directly contact the edge of the frame and the two plates are relatively large, they are not easily damaged during the folding process. Therefore, to facilitate folding, the fold line at this location adopts a dense serrated line. The above-mentioned use of perforated lines as folding lines not only facilitates folding, but also makes it easier to tear the panels of the corner guard apart when the corner guard is removed from the frame, thereby facilitating the removal of the corner guard.
[0045] Among them, Figure 1 In the figure, the thin solid line is the edge line, the thick solid line is the knife line, the dotted line is the pressure line, the relatively sparse dot-dashed line is the sparse tooth knife line, and the relatively dense dot-dashed line is the dense tooth knife line.
[0046] The specific parameters of the perforated line are related to the type and thickness of the cardboard, and can be set on the premise of meeting the above requirements.
[0047] In this embodiment, the bottom guard plate 2 is provided with a process window 21, which can display a barcode, which is convenient for finding and tracking components. In addition, for the corner guard packaged on the left or right side of the frame, the first edging plate 3, the second edging plate 4 and the corner side guard plate 5 on the bottom guard plate 2 are arranged in a mirror image (such as Figure 5 As shown), in order to facilitate distinction, the bottom guard plate 2 is also provided with distinguishing marks 22 "left" and "right", which are used to distinguish the left and right corner guards, so that employees can distinguish the corresponding packages of the corner guards during operation.
[0048] In this embodiment, the photovoltaic module corner protectors are made of corrugated cardboard with fold lines. The cardboard is folded along the fold lines through a bending process to form the corner protectors. Corrugated cardboard provides a better cushioning effect than traditional kraft paper. Corrugated cardboard comes in a variety of styles, and different thicknesses can be selected based on the style. For example, E-type corrugation can have a thickness of 1mm, F-type corrugation can have a thickness of 0.75mm, and G-type corrugation can have a thickness of 0.5mm.
[0049] Example 2
[0050] A photovoltaic module packaging structure, see Figure 6-Figure 7 , including corner protectors 1, protective strips 8 and trays 9, wherein the corner protectors 1 are the photovoltaic module corner protectors as in Example 1. When packaging, the corner protectors are packaged on the four top corners of the photovoltaic module.
[0051] In this embodiment, the protective strip 8 comprises a main body 81 and a plurality of spacers 82 spaced apart from the main body 81. Spacer grooves 83 are formed between adjacent spacers 82. After the four corners of the photovoltaic module are packaged, the modules are placed side by side on a pallet 9. The protective strip 8 is then fastened to the modules, with each module corresponding to a spacer groove 83. This separates the modules and prevents damage during transportation due to contact between the modules. Furthermore, the protective strip 8, through the spacers 82, prevents the modules from falling over and tilting.
[0052] In this embodiment, a plurality of protective strips 8 are provided on each tray 9. The plurality of protective strips 8 are evenly arranged. In this embodiment, there are two protective strips.
[0053] In this embodiment, the material of the protective strip 8 is bobbin paper, which is relatively thin but has a certain strength. The thickness of the spacer guard plate is 1-2 mm. The specific thickness is related to the packaging and placement method of the corner protectors. The first method is to package the corner protectors in intervals (one piece is packaged with the corner protector, and the other piece is not, and they are packaged in sequence). The second method is to fully package the corner protectors. The thickness of the spacer guard plates of the protective strip 8 in the two methods can be referred to the following table:
[0054]
[0055] In other optional embodiments, the material of the protective strip 8 is EPE pearl cotton.
[0056] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
