Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] The string welding machine uses a belt conveyor to transport photovoltaic cells and welding strips for welding. The belt has suction grooves to fix the position of the photovoltaic cells, which are then stacked on the welding strips. However, the placement of the welding strips can easily block the suction grooves, preventing them from providing sufficient suction force to hold the photovoltaic cells, causing them to easily shift on the belt.

[0025] Please see Figure 1 and Figure 2 , Figure 1 This is a top view of a conveying component 100 provided in an embodiment of this application. Figure 2 This is a top view of a conveying component 100 and a photovoltaic module 200 provided in an embodiment of this application. It should be noted that... Figure 1 and Figure 2 In the diagram, AA direction is the width direction of the conveying component 100, and BB direction is the length direction of the conveying component 100.

[0026] Regarding the above issues, firstly, please refer to [the relevant information]. Figure 1 and Figure 2This application provides a conveying component 100, which includes a conveying body 1 and an adsorption structure 2. The conveying body 1 includes a first adsorption region 11 and a second adsorption region 12, with the first adsorption region 11 located on at least one side of the second adsorption region 12 along the width direction of the conveying component 100. The adsorption structures 2 are respectively disposed in the first adsorption region 11 and the second adsorption region 12 for adsorbing photovoltaic modules 200. The number of adsorption structures 2 per unit area in the first adsorption region 11 is greater than or equal to the number of adsorption structures 2 in the second adsorption region 12. It is understood that the conveying body 1 is provided with adsorption structures 2, which can adsorb photovoltaic modules 200 and convey them. Both the first adsorption region 11 and the second adsorption region 12 of the conveying body 1 can adsorb photovoltaic modules 200, and the adsorption force generated by the first adsorption region 11 is greater than the adsorption force generated by the second adsorption region 12, which can compensate for the adsorption force loss caused by the solder ribbon obstruction, thereby reducing the deviation of the photovoltaic modules 200 during the conveying process.

[0027] In a preferred embodiment, the number of adsorption structures 2 per unit area in the first adsorption region 11 is greater than the number of adsorption structures 2 per unit area in the second adsorption region 12.

[0028] Please see Figure 1 In an optional embodiment, the first adsorption region 11 may be located on one or both sides of the second adsorption region 12 along the width direction of the conveying member 100. The embodiments of this application do not limit the location of the first adsorption region 11.

[0029] Please see Figure 1 In optional embodiments, the number of first adsorption regions 11 can be one, two, three, four, etc. The number of second adsorption regions 12 can be one, two, three, four, etc. The embodiments of this application do not limit the number of first adsorption regions 11 and second adsorption regions 12.

[0030] Please see Figure 1 In an optional embodiment, the two ends of the conveying member 100 along its width direction may include a first adsorption region 11 and / or a second adsorption region 12. In other words, both ends of the conveying member 100 along its width direction include the first adsorption region 11. Alternatively, both ends of the conveying member 100 along its width direction include the second adsorption region 12. Or, both ends of the conveying member 100 along its width direction include the first adsorption region 11 and the second adsorption region 12 respectively. The embodiments of this application do not limit the specific placement of the first adsorption region 11 and the second adsorption region 12 on the conveying member 100.

[0031] Please see Figure 1In some embodiments, both the first adsorption region 11 and the second adsorption region 12 include multiple regions. The first adsorption regions 11 and the second adsorption regions 12 are alternately distributed along the width direction of the conveying member 100, and the first adsorption region 11 is included at both ends of the conveying member along its own width direction. In other words, the first adsorption region 11 is provided on both sides of the conveying body 1, which can improve the adsorption force of the conveying member 100 on both sides of its own width towards the photovoltaic module 200, thereby limiting the edge of the photovoltaic module 200 and further reducing the offset of the photovoltaic module 200.

[0032] In an optional embodiment, there are two first adsorption regions 11 and one second adsorption region 12. The two first adsorption regions 11 are located on both sides of the conveying member 100 along its width direction. The first adsorption regions 11 and the second adsorption regions 12 are alternately distributed in the width direction of the conveying member 100; in other words, the second adsorption region 12 is located between the two first adsorption regions 11. Since the number of adsorption structures 2 per unit area in the first adsorption region 11 is greater than the number of adsorption structures 2 per unit area in the second adsorption region 12, the adsorption force on both sides of the conveying member 100 is greater, which can improve the adsorption of the photovoltaic module 200.

[0033] In other optional embodiments, the conveying member 100 includes three first adsorption regions 11 and two second adsorption regions 12. Two of the first adsorption regions 11 are located along the two side edges of the conveying member 100 along its width direction, and the other first adsorption region 11 is located in the middle of the conveying member 100 along its width direction. The two second adsorption regions 12 are respectively sandwiched between the three first adsorption regions 11. Since the number of adsorption structures 2 per unit area of ​​the first adsorption region 11 is greater than the number of adsorption structures 2 per unit area of ​​the second adsorption region 12, the adsorption force in the middle and side edges of the conveying member 100 is greater, which can further improve the adsorption of the photovoltaic module 200.

[0034] The specific distribution of adsorption structure 2 in the first adsorption region 11 and the second adsorption region 12 will be described below.

[0035] In optional embodiments, the adsorption structures 2 in the first adsorption region 11 can be randomly arranged or arranged in an array. This application does not limit the specific distribution of the adsorption structures 2 in the first adsorption region 11.

[0036] Please see Figure 1In some embodiments, the first adsorption region 11 includes a plurality of first sub-adsorption regions 111 spaced apart. In each first sub-adsorption region 111, a plurality of adsorption structures 2 are spaced apart along the width direction of the conveying member 100 to form adsorption groups 111a, and the plurality of adsorption groups 111a are spaced apart along the length direction of the conveying member 100. The arrangement of multiple first sub-adsorption regions 111 in the first adsorption region 11 enables a more uniform adsorption force in the first adsorption region 11. The adsorption groups 111a can increase the number of adsorption structures 2 per unit area in the first adsorption region 11, resulting in a higher adsorption force per unit area in the first adsorption region 11.

[0037] In an optional embodiment, the first sub-adsorption regions 111 may be spaced apart along the width direction of the conveying member 100 or spaced apart along the length direction of the conveying member 100.

[0038] In an optional embodiment, the adsorption groups 111a in two adjacent first sub-adsorption regions 111 can be staggered or aligned.

[0039] Please see Figure 1 In some embodiments, in the first adsorption region 11, each first sub-adsorption region 111 is distributed at intervals along the width direction of the conveying member 100, and the adsorption groups 111a in two adjacent first sub-adsorption regions 111 are staggered. The staggered adsorption groups 111a can increase the adsorption area of ​​the first adsorption region 11, thereby improving the adsorption capacity of the first adsorption region 11.

[0040] In an optional embodiment, the adsorption structures 2 in the second adsorption region 12 can be randomly arranged or arranged in an array. This application embodiment does not limit the specific distribution of the adsorption structures 2 in the second adsorption region 12.

[0041] Please see Figure 1 In some embodiments, the second adsorption region 12 includes a plurality of second sub-adsorption regions 121 spaced apart, wherein in each second sub-adsorption region 121, a plurality of adsorption structures 2 are spaced apart along the length direction of the conveying member 100. The provision of a plurality of second sub-adsorption regions 121 in the second adsorption region 12 enables a more uniform adsorption force in the second adsorption region 12.

[0042] In an optional embodiment, the second sub-adsorption regions 121 may be spaced apart along the width direction of the conveying member 100 or spaced apart along the length direction of the conveying member 100.

[0043] In an optional embodiment, the adsorption structures 2 in two adjacent second sub-adsorption regions 121 may be staggered or aligned.

[0044] Please see Figure 1In some embodiments, in the second adsorption region 12, each second sub-adsorption region 121 is distributed at intervals along the width direction of the conveying member 100, and the adsorption structures 2 in adjacent second sub-adsorption regions 121 are staggered. The staggered arrangement of the adsorption structures 2 in the second sub-regions can increase the adsorption area of ​​the second adsorption region 12, thereby improving the adsorption capacity of the second adsorption region 12.

[0045] In an optional embodiment, the conveying body 1 of the conveying member 100 may be a flexible conveyor belt, such as a polyurethane conveyor belt, a silicone conveyor belt, a belt, etc.

[0046] Please see Figure 1 and Figure 2 In some embodiments, the adsorption structure 2 includes adsorption holes 21 that penetrate the conveying body 1 along the thickness direction of the conveying member 100. The adsorption holes 21 are easy to create and allow for more uniform adsorption.

[0047] It should be noted that the photovoltaic modules are conveyed by a belt in the stringer. Photovoltaic modules typically consist of a bonding strip and solar cells. The bonding strip is placed on the belt, and the solar cells are placed on the bonding strip and welded to it. Due to long-term use, the belt position may shift, causing the bonding strip to block the suction grooves on the belt. Currently, the grooves on the belt are relatively large, causing the bonding strip to be sucked into the grooves, resulting in bending of the bonding strip and consequently, weak solder joints at the corresponding locations on the solar cells, leading to cell defects. For further information on this issue, please refer to [link to relevant documentation]. Figure 2 In some embodiments, the outline of the adsorption hole 21 is circular, and the diameter D of the adsorption hole 21 satisfies: 0.30mm≤D≤0.55mm. Controlling the diameter of the adsorption hole 21 within the above range, and making the diameter of the adsorption hole 21 slightly larger than the width of the solder ribbon, can ensure the adsorption force of the adsorption hole 21 while avoiding the solder ribbon being sucked into the hole, thereby avoiding solder ribbon bending, reducing incomplete soldering, and reducing defects in the battery cell 201.

[0048] For example, the diameter D of the adsorption pore 21 can be any value within the above range, such as 0.30mm, 0.35mm, 0.40mm, 0.45mm, 0.50mm, 0.55mm, etc.

[0049] Please see Figure 2 Secondly, embodiments of this application provide a conveying device, which includes a conveying member 100 for adsorbing and conveying photovoltaic modules 200. The conveying member 100 is the same as described in the first aspect. Optional conveying devices may be string welding machines or shingled welding machines.

[0050] Please see Figure 2Thirdly, embodiments of this application also provide a conveying system, which includes a conveying device and a photovoltaic module 200. The conveying device includes a conveying component 100, which is the conveying component 100 as described in the first aspect. The photovoltaic module 200 includes a cell 201 and a connector 202, which is connected to the cell 201. The conveying component 100 is used to adsorb the cell 201 and convey the photovoltaic module 200.

[0051] Please see Figure 2 In an optional embodiment, when the conveying device is a stringer, the photovoltaic module 200 includes solar cells 201 and welding ribbon. The welding ribbon is disposed outside the suction holes 21 of the belt of the stringer, and the welding ribbon is arranged at intervals along the width of the belt. The solar cells 201 are stacked on the welding ribbon, and the welding points on the solar cells 201 correspond to and are welded to the welding ribbon.

[0052] In other alternative embodiments, when the conveying device is a shingled welding machine, the photovoltaic module 200 includes solar cells 201 and conductive adhesive. The conductive adhesive is applied to the solar cells 201 and is used to connect two solar cells 201 with overlapping edges.

[0053] Please see Figure 1 and Figure 2 In summary, the conveying member 100 provided in this application embodiment can improve the adsorption force of the conveying member 100 on the photovoltaic module 200 by making the number of adsorption structures 2 per unit area in the first adsorption region 11 greater than the number of adsorption structures 2 in the second adsorption region 12. Simultaneously, by ensuring that the adsorption structures 2 on both the first and second adsorption regions 11 are adsorption holes 21 with a diameter D satisfying 0.30mm ≤ D ≤ 0.55mm, the adsorption force can be guaranteed while preventing the solder ribbon from being sucked into the holes, thereby reducing the bending of the solder ribbon, reducing welding defects of the solar cells 201, and thus improving the production quality of the photovoltaic module 200.
