Detailed Description

Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

A packaging assembly 1000 according to an embodiment of the invention is described below with reference to fig. 1-9.

As shown in fig. 1, a package assembly 1000 according to an embodiment of the present invention includes a package box 100, at least one strapping band 200, a photovoltaic module assembly 300, and a tray 400.

Specifically, the photovoltaic module assembly 300 includes a plurality of photovoltaic modules 301 standing side by side, and the lateral dimension of the photovoltaic module assembly 300 is relatively small, so that the lateral space occupied by the photovoltaic module assembly 300 in the container can be reduced during transportation. Here, it should be noted that "standing up" means that the short side 3012 of each photovoltaic module 301 contacts the ground, and the long side 3011 of each photovoltaic module 301 is perpendicular to the ground.

At least one packing belt 200 is wound on the outer side of the photovoltaic module assembly 300 to fix a plurality of photovoltaic modules 301 of the photovoltaic module assembly 300 together, so that the photovoltaic modules 301 of the photovoltaic module assembly 300 are not easy to move relatively in the packaging and transporting processes, the packaging efficiency can be improved, and the photovoltaic modules 301 can be effectively prevented from being damaged. The tray 400 is provided at the bottom of the photovoltaic module assembly 300 to support the photovoltaic module assembly 300.

Referring to fig. 1-6, a package 100 includes a plurality of sidewalls 1. In the description of the present invention, "a plurality" means two or more. The package 100 shown in fig. 1-6 includes four side walls 1 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solution of the present application that the solution can be applied to three, five or more side walls 1, which also falls within the protection scope of the present invention.

Specifically, referring to fig. 1, the sidewalls 1 are sequentially connected end to end along the outer circumference of the photovoltaic module assembly 300 to form a hollow enclosure box with open upper and lower ends, so that the packing box 100 can pack the photovoltaic module assembly 300 for transportation. At least one of the plurality of side walls 1 is a first side wall 11, the first side wall 11 has a fold line 111, the fold line 111 divides the first side wall 11 into a first side wall part 112 and a second side wall part 113, and the first side wall part 112 is foldable and/or tearable relative to the second side wall part 113 so as to facilitate taking out the photovoltaic module 301 packaged in the packaging box 100.

Alternatively, the fold line 111 may be formed by providing a dashed line type indentation (as shown in fig. 4) or a solid line type indentation (as shown in fig. 6) on the first side wall 11 to facilitate the operator to fold and/or tear the first side wall portion 112 along the fold line. Here, it should be noted that the fold line 111 can also be implemented in other manners as long as it is convenient for an operator to fold or tear the first sidewall portion 112 along the fold line 111.

When an operator takes out the photovoltaic module 301 from the packaging box 100, the first side wall 112 may be only folded outwards relative to the second side wall 113, and at this time, the first side wall 112 and the second side wall 113 are always connected; alternatively, the first side wall portion 112 may be torn with respect to the second side wall portion 113, and the first side wall portion 112 may be separated from the second side wall portion 113; alternatively, when a part of the first side wall portion 112 is folded back with respect to the second side wall portion 113 and the other part of the first side wall portion 112 is torn off with respect to the second side wall portion 113, the first side wall portion 112 and the second side wall portion 113 are partially connected. It is understood that the operator can selectively fold or tear the first sidewall portion 112 relative to the second sidewall portion 113 according to the actual operation requirement, so as to perform the operation of removing the photovoltaic module 301.

For example, taking the example that the packaging box 100 shown in fig. 1 includes four side walls 1, the packaging box 100 is arranged around a plurality of photovoltaic modules 301 which are arranged vertically side by side, wherein the first side wall 11 of the packaging box 100 may be arranged opposite to one of the outer side surfaces of the photovoltaic module assembly 300. When it is desired to remove a plurality of photovoltaic modules 301 from the package 100, the first side wall 112 may be folded and/or torn relative to the second side wall 113 along the fold line 111 to expose a portion of the height of each photovoltaic module 301, so that each photovoltaic module 301 may be conveniently removed.

According to the packaging assembly 1000 of the embodiment of the invention, the plurality of photovoltaic modules 301 in the photovoltaic module assembly 300 are arranged to be vertically placed side by side, the plurality of side walls 1 of the packaging box 100 are sequentially connected end to end along the outer peripheral side of the photovoltaic module assembly 300, at least one first side wall 11 in the plurality of side walls 1 is provided with the folding line 111, the first side wall 11 is divided into the first side wall part 112 and the second side wall part 113 through the folding line 111, the first side wall part 112 can be folded and/or torn relative to the second side wall part 113, the packaging box 100 can be unpacked simply and quickly, the photovoltaic modules 301 packaged in the packaging box 100 can be taken out more conveniently, and labor is saved. Moreover, the photovoltaic module 301 can be vertically loaded into a container for transportation, and the space in the container is fully utilized, so that the transportation cost can be saved.

According to some embodiments of the invention, each photovoltaic module 301 has a long side 3011 and a short side 3012, and the first side wall 111 faces the long side 3011 of the plurality of photovoltaic modules 301 (not shown). With the arrangement, when the photovoltaic module 301 is taken out, the first side wall part 112 is folded and/or torn relative to the second side wall part 113, so that an operator can conveniently take out the photovoltaic module 301 from the side of the photovoltaic modules (namely, the side where the long edge 3011 of the photovoltaic modules 301 is located), and the disassembly efficiency can be improved, and the labor is saved.

According to some alternative embodiments of the present invention, referring to fig. 2, 4 and 6, both ends of the folding line 111 extend to both sidewalls 1 adjacent to the first sidewall 11, respectively, and both sidewalls 1 adjacent to the first sidewall 11 are detachably connected to the first sidewall part 112. At this time, in the first side wall 11, one side of the folding line 111 is a first side wall 112, the other side of the folding line 111 is a second side wall 113, and both ends of the first side wall 112 are detachably connected to the adjacent two side walls 1. With this arrangement, the manufacture of the fold line 111 is simpler, thereby improving the manufacturing efficiency of the packing case 100. In addition, when the photovoltaic module 301 packaged in the packaging box 100 needs to be taken out, the operator only needs to separate the first side wall portion 112 from the two side walls 1, and turn and/or tear the first side wall portion 112 relative to the second side wall portion 113 along the folding line 111 to take out the photovoltaic module 301, so that the operation before taking out the photovoltaic module 301 is simplified. Furthermore, the fold line 111 is arranged such that after the first side wall portion 112 is folded and/or torn with respect to the second side wall portion 113, more of the long side 3011 of the photovoltaic module 301 is exposed to a larger portion, thereby facilitating the removal of more of the photovoltaic module 301.

According to some embodiments of the present invention, referring to fig. 2, each of the two sidewalls 1 adjacent to the first sidewall 11 is a second sidewall 12, one of the first sidewall 112 and the second sidewall 12 has a first flap 13 thereon, and the other of the first sidewall 112 and the second sidewall 12 is detachably connected to the first flap 13 by a first adhesive 14. Alternatively, as shown in fig. 2, the first sidewall 112 has a first folded edge 13, and both of the second sidewalls 12 are detachably connected to the first folded edge 13 of the first sidewall 112 by the first adhesive member 14. Alternatively, the two second side walls 12 each have a first folded edge 13, and the first side wall portion 112 is detachably connected to the respective first folded edges 13 of the two second side walls 12 by a first adhesive member 14 (not shown). In any case, the detachable connection between the first sidewall 112 and the two adjacent sidewalls 1 is simple, which is convenient for the operator to operate, thereby improving the packing or unpacking efficiency of the whole packing assembly 1000, and the recycling rate of the packing box 100 is high.

In some embodiments of the present invention, as shown in fig. 2, 4 and 6, the width of the first flap 13 gradually decreases in a direction away from the center of the first sidewall portion 112. At this time, both ends of the first folded edge 13 are gradually closed from the first side wall portion 112 toward a direction away from the first side wall portion 112, and thus, when the photovoltaic module 301 is packaged in the packaging box 100, when the first side wall portion 112 is connected to the two side walls 1 adjacent to the first side wall portion 112, the first folded edge 13 of the first side wall portion 112 can be more closely attached to the two side walls 1 adjacent to the first side wall portion 112, and the first folded edge 13 of the first side wall portion 112 can save materials, so that the packaging box 100 is low in cost, and the whole packaging assembly 1000 is low in cost.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the width of the first folding edge 13 is equal in a direction away from the center of the first sidewall part 112. So set up, first hem 13 shaping is simple to whole packing box 100 shaping is simple, improves packing box 100's manufacturing efficiency.

Optionally, the first adhesive member 14 is a hook and loop fastener or a double-sided tape. When the first adhesive member 14 adopts the hook and loop fastener, the detachable connection between the first sidewall portion 112 and the two adjacent sidewalls 1 can be repeatedly used, thereby improving the utilization rate of the packing box 100 and saving the cost. When the first adhesive member 14 is a double-sided adhesive tape, the first sidewall 112 and the two adjacent sidewalls 1 are firmly connected due to the high viscosity of the double-sided adhesive tape. Of course, the present invention is not limited thereto, and the first adhesive member 14 may have other adhesive structures.

According to some alternative embodiments of the present invention, as shown in fig. 2, the plurality of side walls 1 are integrally formed pieces. With such an arrangement, the manufacturing steps of the whole packaging box 100 can be reduced, and the manufacturing efficiency can be improved. In addition, the packaging steps of the photovoltaic module 301 are reduced, thereby saving labor cost.

For example, when the photovoltaic module 301, particularly a large-sized photovoltaic module, is packaged to form the packaging aggregate 1000 using the packaging box 100 in which the plurality of side walls 1 are integrally formed, first, the plurality of photovoltaic modules 301 of the photovoltaic module aggregate 300 are placed on the circulation tray 500, for example, the plurality of photovoltaic modules 301 may be stacked on the circulation tray 500 up and down; then, packaging the photovoltaic modules 301 by using a packaging belt 200; then, turning the packaged photovoltaic assembly 300 to be vertically placed on the tray 400; then the packing box 100 is sleeved on the outer peripheral side of the vertically placed photovoltaic assembly 300 from top to bottom; finally, the packing belt 200 may be further used to pack the photovoltaic module assembly 300 and the packaging box 100, and a film may be wound to further fix the photovoltaic module assembly 300 and the packaging box 100 firmly.

In the above-described packing process, the packing tape 200 may include at least one of the first packing tape 2001 and the second packing tape 2002, the first packing tape 2001 may be wound around an outer circumferential side of the photovoltaic module aggregate 300 in a circumferential direction of the photovoltaic module aggregate 300, and the second packing tape 2002 may be wound around an outer side of the plurality of photovoltaic modules 301 of the photovoltaic module aggregate 300 in a stacking direction of the plurality of photovoltaic modules 301. With this arrangement, the plurality of photovoltaic modules 301 of the photovoltaic module assembly 300 can be stably fixed together, so that packaging is facilitated, and relative displacement of the plurality of photovoltaic modules 301 can be prevented in the process of transporting the packaging assembly 1000, so that the photovoltaic modules 301 are not easily damaged.

Further, the strapping band 200 may include two first strapping bands 2001 and two second strapping bands 2002, the two first strapping bands 2001 may be respectively located at the upper end and the lower end of the photovoltaic module assembly 300, and the two second strapping bands 2002 may be respectively located at two sides of the photovoltaic module 301 in the width direction, so that all the photovoltaic modules 301 in the photovoltaic module assembly 300 may be reliably fixed together, the material of the strapping band 200 is saved, the cost is saved, and the assembly and disassembly efficiency is improved.
