[0003] When the cell piece is applied to a photovoltaic power generation device, a plurality of independent cell pieces and a conductive connecting piece (i.e., a solder strip) are usually welded to form a cell string to improve the photoelectric conversion efficiency of the photovoltaic power generation device. In the prior art, the conductive connecting piece is wound on a carrier. When the cell string is processed, the conductive connecting piece on the carrier needs to be cut off, and the cut-off conductive connecting piece is laid on a workbench, and then the welding of the conductive connecting piece and the cell piece is performed. However, in the prior art, the conductive connecting piece will be scattered after being cut off, and personnel need to manually arrange the conductive connecting piece, which increases an additional arrangement process, thereby reducing the processing efficiency of the cell string.

[0011] Further, the carrier further comprises a fixing seat located between the rotating body and the first fixing mechanism, the fixing seat abuts against and supports the first fixing mechanism.

[0012] Further, the fixing seat is protruded away from the rotation axis of the rotating body to form an abutting portion, and the first fixing mechanism abuts against the abutting portion when the inserting member is inserted into the inserting slot.

[0026] As Figure 1 and Figure 2As shown, the application provides a carrier 100, which comprises a rotating body 11, a first fixing assembly 12, a first fixing mechanism 13 and a second fixing mechanism 14. The rotating body 11 has a rotating degree of freedom and is used to wind the conductive connecting piece to realize the collection of the conductive connecting piece. The first fixing assembly 12 is used to fix the first fixing mechanism 13. The second fixing mechanism 14 is connected with the first fixing mechanism 13 in a matched mode to form a first fixing space for fixing the conductive connecting piece. The first fixing space refers to the space between the first fixing mechanism 13 and the second fixing mechanism 14 for clamping the conductive connecting piece. In this way, the conductive connecting piece close to the first fixing space is cut, and after the cutting is completed, the first fixing space can fix the cut part of the conductive connecting piece, thereby avoiding the scattering of the conductive connecting piece at the cut part and the need to increase an additional process of arranging the conductive connecting piece, and thus the processing efficiency of the battery string is improved.

[0027] It should be noted that in the embodiment of the application, the first fixing mechanism 13 is arranged on the side of the conductive connecting piece close to the rotating body 11, and the second fixing mechanism 14 is arranged on the side away from the rotating body 11, so that the first fixing space formed by the second fixing mechanism 14 and the first fixing mechanism 13 can clamp and fix the conductive connecting piece.

[0028] It should be noted that the conductive connecting piece in the embodiment of the application is a welding strip woven by welding wires. Therefore, after the conductive connecting piece is cut, the welding wires lack pre-tightening force, thereby causing the scattering of the conductive connecting piece at the cut part. In the embodiment of the application, the first fixing space can fix the cut part of the conductive connecting piece, thereby providing the pre-tightening force between the welding wires to avoid the scattering of the conductive connecting piece at the cut part, and thus the processing efficiency of the battery string is improved.

[0029] Specifically, the first fixing mechanism 13 is provided with a plug-in groove 131, and the first fixing mechanism 13 is detachably connected with the rotating body 11 through the plug-in groove 131. More specifically, the first fixing assembly 12 comprises a driving piece 121 and a plug-in piece 122. The driving piece 121 is installed on the rotating body 11, and the plug-in piece 122 is connected with the driving piece 121, so that the plug-in piece 122 has a fixed position for plugging into the plug-in groove 131 and a separation position for separating from the plug-in groove 131. The fixed position refers to the position of the plug-in piece 122 when the plug-in piece 122 is fixedly connected with the plug-in groove 131, and the separation position refers to the position of the plug-in piece 122 when the plug-in piece 122 is separated from the plug-in groove 131. When the plug-in piece 122 moves to the fixed position, the first fixing mechanism 13 is fixed on the rotating body 11 through the plug-in piece 122, and when the plug-in piece 122 moves to the separation position, the first fixing mechanism 13 is separated from the rotating body 11.

[0030] Through the above setting, when the plug-in part 122 is in the fixed position, the plug-in part 122 is plugged with the plug-in groove 131, so that the first fixing mechanism 13 can be connected with the rotating main body 11, thereby the position of the conductive connecting part fixed in the first fixing space relative to the rotating main body 11 can be limited, so that the first fixing mechanism 13 and the second fixing mechanism 14 can tension the conductive connecting part at the first fixing space, so as to avoid the flexible characteristic of the conductive connecting part to cause the conductive connecting part to be unable to be cut off, thereby facilitating to improve the cutting efficiency of the conductive connecting part on the carrier 100. Secondly, the first fixing mechanism 13 and the carrier 100 can be detachably fixed through the above setting, so that the first fixing mechanism 13 can be fixed or separated from the carrier 100, so as to facilitate the subsequent processing of the conductive connecting part, thereby improving the processing efficiency of the battery string.

[0031] It should be noted that, compared with the way of using adhesion or magnetic adsorption to realize the connection of the first fixing mechanism 13 and the rotating main body 11, the way of plugging the plug-in part 122 with the plug-in groove 131 can improve the connection stability between the first fixing mechanism 13 and the rotating main body 11, thereby improving the clamping stability of the first fixing mechanism 13 and the second fixing mechanism 14 on the conductive connecting part, so as to facilitate the cutting of the conductive connecting part. And it is also beneficial to improve the disassembly convenience between the first fixing mechanism 13 and the rotating main body 11.

[0032] In addition, when the plug-in part 122 is in the separated position, by separating the plug-in part 122 from the plug-in groove 131, the first fixing mechanism 13 and the second fixing mechanism 14 can be separated from the rotating main body 11, so that after the cutting of the conductive connecting part is completed, the first fixing mechanism 13 and the second fixing mechanism 14 can be arranged together with the conductive connecting part on the processing platform of the battery string, so as to avoid the situation that the cut of the conductive connecting part is scattered during the arrangement of the conductive connecting part, and at the same time, it is beneficial to the subsequent processing of the conductive connecting part, thereby improving the processing efficiency of the battery string.

[0033] It should be noted that the plug-in part 122 moves between the fixed position and the separated position, so that the first fixing mechanism 13 and the carrier 100 can be detachably fixed, thereby the first fixing mechanism 13 can be fixed or separated from the carrier 100, so as to facilitate the subsequent processing of the conductive connecting part, thereby improving the processing efficiency of the battery string.

[0034] It should be noted that in the present application, the conductive connecting piece can be wound on the carrier 100 first, then the first fixing mechanism 13 is connected with the rotating body 11, and finally the second fixing mechanism 14 is connected with the first fixing mechanism 13, so that the conductive connecting piece is fixed in the first fixing space, thereby limiting the conductive connecting piece and the rotating body 11; or the first fixing mechanism 13 can be connected with the rotating body 11 first, then the conductive connecting piece is wound on the carrier 100, and finally the second fixing mechanism 14 is connected with the first fixing mechanism 13, so that the conductive connecting piece is fixed in the first fixing space, thereby limiting the conductive connecting piece and the rotating body 11. Therefore, the present application does not limit the limiting steps of the conductive connecting piece and the rotating body 11.

[0035] As an embodiment, the plug-in piece 122 is located on one side of the first fixing mechanism 13 in the rotation direction of the rotating body 11. In this way, the space utilization rate of the rotating body 11 can be improved, so as to improve the structural compactness of the carrier 100.

[0036] As an embodiment, the driving piece 121, the plug-in piece 122 and the first fixing mechanism 13 are distributed along the rotation direction of the rotating body 11, and the plug-in piece 122 is located between the driving piece 121 and the first fixing mechanism 13. In this way, the driving piece 121 can drive the plug-in piece 122 to approach or move away from the first fixing mechanism 13, so as to connect or separate the first fixing mechanism 13 and the rotating body 11.

[0037] For example, when the driving piece 121 drives the plug-in piece 122 to approach the first fixing mechanism 13, so that the plug-in piece 122 is in a fixed position, the plug-in piece 122 is plugged with the plug-in slot 131, and then the first fixing mechanism 13 is connected with the rotating body 11; when the driving piece 121 drives the plug-in piece 122 to move away from the first fixing mechanism 13, so that the plug-in piece 122 is in a separation position, the plug-in piece 122 is separated from the plug-in slot 131, and then the first fixing mechanism 13 is separated from the rotating body 11.

[0038] As another embodiment, the driving piece 121 is located between the first fixing mechanism 13 and the rotating body 11, and the plug-in piece 122 is at least partially located on one side of the driving piece 121 and the first fixing mechanism 13 in the rotation direction of the rotating body 11. In this way, when the driving piece 121 drives the plug-in piece 122 to be in a fixed position, the first fixing mechanism 13 is connected with the rotating body 11, and when the driving piece 121 drives the plug-in piece 122 to be in a separation position, the first fixing mechanism 13 is separated from the rotating body 11, thereby realizing the disassembly between the first fixing mechanism 13 and the rotating body 11.

[0039] In addition, by the above arrangement, the space occupancy ratio of the driving member 121, the plug-in member 122 and the first fixing mechanism 13 along the rotation direction of the rotating body 11 can be reduced, so as to improve the structural compactness of the carrier 100.

[0040] It should be noted that in the present application, the plug-in groove 131 and the plug-in member 122 can be interchanged, i.e., the first fixing mechanism 13 is provided with a plug-in member (not shown in the figure), and the first fixing assembly 12 is provided with a plug-in groove (not shown in the figure), the separation position of the plug-in member 122 is the separation position of the plug-in groove, and the fixed position of the plug-in member 122 is the fixed position of the plug-in groove. Therefore, the plug-in groove can be moved between the fixed position and the separation position by the driving member 121, i.e., the detachable fixing of the first fixing mechanism 13 and the first fixing assembly 12 can be realized. Therefore, the present application does not limit the arrangement of the plug-in groove 131 and the plug-in member 122 on the first fixing mechanism 13 and the first fixing assembly 12, as long as the first fixing mechanism 13 and the first fixing assembly 12 can be detachably fixed by the plug-in groove 131 and the plug-in member 122.

[0041] As an embodiment, the carrier 100 further comprises a fixing seat 18, which is located between the rotating body 11 and the first fixing mechanism 13. Specifically, the fixing seat 18 abuts against and supports the first fixing mechanism 13. In this way, the first fixing mechanism 13 can be supported by the fixing seat 18, so as to improve the connection stability of the first fixing mechanism 13 and the rotating body 11.

[0042] As an optional implementation, the fixing seat 18 is protruded away from the rotation axis direction of the rotating body 11 to form an abutting portion 181, i.e., the abutting portion 181 is protruded along the radial direction of the rotating body 11. When the plug-in member 122 is plugged into the plug-in groove 131, the first fixing mechanism 13 abuts against the abutting portion 181. In this way, the first fixing mechanism 13 can be limited by the abutting portion 181, so as to improve the connection stability of the first fixing mechanism 13 and the rotating body 11. In addition, a cutting gap can be reserved by the abutting portion 181, so that a tool for cutting the conductive connecting member can cut the conductive connecting member through the cutting gap. Specifically, the plug-in groove 131 is located on one side of the first fixing mechanism 13 along the circumferential direction of the rotating body 11, and when the plug-in member 122 is plugged into the plug-in groove 131, the abutting portion 181 abuts against the side of the first fixing mechanism 13 away from the plug-in groove 131.

[0043] As an implementation form, the first fixing assembly 12 further comprises a guide rod 123 connected to the driving member 121 and the plug-in member 122, and the fixing base 18 is provided with a guide groove 182 for guiding the guide rod 123, and the guide rod 123 is located in the guide groove 182. In this way, the movement of the plug-in member 122 can be guided by the cooperation of the guide rod 123 and the guide groove 182, thereby improving the stability of the movement of the plug-in member 122, and improving the stability of the connection between the plug-in member 122 and the plug-in groove 131, and further improving the stability of the connection between the first fixing mechanism 13 and the rotating main body 11.

[0044] As an implementation form, the first fixing mechanism 13, the second fixing mechanism 14 and the first fixing assembly 12 are all provided with two. Along the rotation direction of the rotating main body 11, the two first fixing mechanisms 13 are located between the two first fixing assemblies 12, and each first fixing mechanism 13 corresponds to a second fixing mechanism 14. In this way, the two first fixing mechanisms 13 can cooperate with the corresponding second fixing mechanisms 14 to form two first fixing spaces. In the embodiment of the present application, the cutting part of the conductive connecting piece is located between the two first fixing mechanisms 13. Therefore, the two ends of the cutting part of the conductive connecting piece can be fixed by the two first fixing spaces, so that the two first fixing spaces can provide a pre-tightening force to the conductive connecting piece, thereby facilitating the cutting of the conductive connecting piece.

[0045] Specifically, after the two plug-in members 122 of the two first fixing assemblies 12 are respectively plugged into the two first fixing mechanisms 13, the sides of the two first fixing mechanisms 13 away from the plug-in groove 131 are respectively abutted along the two sides of the rotating main body 11 in the circumferential direction. Among them, the abutment part 181 is arranged to reserve a cutting gap between the two first fixing mechanisms 13, so that the tool for cutting the conductive connecting piece can cut the conductive connecting piece through the cutting gap.

[0046] In some embodiments, in some embodiments, the driving member 121 is a double-headed cylinder, which can drive the movement of the two first fixing assemblies 12 at the same time, without the need to additionally install a driving device to control the movement of the two first fixing assemblies 12 respectively, thereby reducing the number of parts in the rotating main body 11, thereby facilitating the improvement of the space utilization rate in the rotating main body 11.

[0047] As another implementation form, the carrier 100 can also comprise a pressing plate and a cylinder. Among them, the pressing plate is distributed along the rotation direction of the rotating main body 11 with the second fixing mechanism 14, and the cylinder is fixed to the rotating main body 11, and the cylinder is used to drive the movement of the pressing plate, so that the pressing plate can cooperate with the rotating main body 11 to fix the conductive connecting piece. In the embodiment of the present application, the cutting part of the conductive connecting piece is located between the second fixing mechanism 14 and the pressing plate.

[0048] It can be understood that, along the rotation direction of the rotating body 11, the two ends of the cutting part of the conductive connecting piece are defined as the first end and the second end respectively. The first end is fixed through one of the two first fixed spaces or the pressing plate, and the second end is fixed through the other of the two first fixed spaces. Therefore, the fixing mode of the first end of the conductive connecting piece is not limited in the present application. In addition, the present application is described by taking the example of providing two first fixed spaces.

[0049] As an embodiment, the second fixing mechanism 14 is bonded with the first fixing mechanism 13, or the second fixing mechanism 14 is connected with the first fixing mechanism 13 through magnetism. In this way, the second fixing mechanism 14 and the first fixing mechanism 13 can be fixed through bonding or magnetic connection, so that the second fixing mechanism 14 and the first fixing mechanism 13 cooperate to form the first fixed space, thereby being able to fix the two ends of the cutting part of the conductive connecting piece.

[0050] It should be noted that the connection mode of the second fixing mechanism 14 and the first fixing mechanism 13 is not limited in the present application.

[0051] As an embodiment, the rotating body 11 has a bearing surface 111, which is arranged around the rotation axis of the rotating body 11 and is used for winding the conductive connecting piece. Specifically, the rotating body 11 is provided with a mounting groove 112, which has at least one opening on the bearing surface 111. The first fixing assembly 12 is mounted in the mounting groove 112, and the first fixing mechanism 13 is fixed in the mounting groove 112 through the first fixing assembly 12. In this way, the first fixing mechanism 13 can be provided with a mounting channel through the opening, so as to avoid the interference of the first fixing mechanism 13 with the winding of the conductive connecting piece on the bearing surface 111, thereby facilitating the improvement of the space utilization of the rotating body 11.

[0052] As an optional implementation, when the second fixing mechanism 14 is connected with the first fixing mechanism 13, the second fixing mechanism 14 is located outside the mounting groove 112, and the first fixed space is flush with the opening of the mounting groove 112. In this way, when the first fixing mechanism 13 cooperates with the second fixing mechanism 14 to fix the conductive connecting piece, the first fixing mechanism 13 is located in the mounting groove 112, and the second fixing mechanism 14 is located outside the mounting groove 112, so that the conductive connecting piece does not recess into the mounting groove 112 and does not protrude from the bearing surface 111 at the mounting groove 112, thereby avoiding the interference of the first fixing mechanism 13 and the second fixing mechanism 14 with the winding of the conductive connecting piece on the carrier 100, so as to avoid the excessive deformation of the conductive connecting piece, and further avoid the bending and breaking of the conductive connecting piece due to the excessive deformation of the conductive connecting piece, thereby improving the material utilization of the conductive connecting piece.

[0053] As Figure 4As shown, the present application provides a processing device 200 of the conductive connecting piece, the processing device 200 comprises a fixing piece 21 and a processing assembly 22. Specifically, the fixing piece 21 is used for fixing the conductive connecting piece. The processing assembly 22 is used for connecting the fixing piece 21 with the conductive connecting piece.

[0054] In some embodiments, the fixing piece 21 is a bus bar. In this way, the current generated by the photoelectric conversion of the battery piece can be collected through the bus bar to facilitate the output of the current in the battery string. Moreover, the bus bar can also fix the conductive connecting piece to avoid the scattering of the conductive connecting piece, which is conducive to improving the processing efficiency of the battery string and improving the structural stability of the battery string. As another implementation, the fixing piece 21 can be provided as a metal strip, which can be welded with the conductive connecting piece. Only after the fixing piece 21 is laid along the conductive connecting piece, the fixing piece 21 can be cut and separated from the conductive connecting piece. In summary, the structure of the fixing piece 21 is not limited in the present application.

[0055] In the present embodiment, the processing assembly 22 comprises an operating mechanism 221, which is used for transferring the fixing piece 21. Specifically, the operating mechanism 221 is movable so that the operating mechanism 221 has a placement position close to the carrier 100. When the operating mechanism 221 is in the placement position, the operating mechanism 221 can place the fixing piece 21 on the conductive connecting piece so that the fixing piece 21 can be connected with the conductive connecting piece to fix the conductive connecting piece. For example, the operating mechanism 221 can be a mechanical arm, which can pick up the fixing piece 21 and move the fixing piece 21 to the placement position so that the mechanical arm can place the fixing piece 21 on the conductive connecting piece.

[0056] It can be understood that in the present application, the conductive connecting piece is a solder strip and the number of the conductive connecting pieces is not unique. Therefore, after the conductive connecting piece is cut off, the cut end of the conductive connecting piece is divided into two ends. Since the two ends of the conductive connecting piece lose connection, the conductive connecting piece will appear scattered. However, due to the arrangement of the fixing piece 21, when the conductive connecting piece is cut off, the fixing piece 21 can avoid the scattering of the conductive connecting piece, so that when the conductive connecting piece moves, the conductive connecting pieces will not contact each other, thereby avoiding the short circuit between the battery pieces due to the contact between the conductive connecting pieces; at the same time, the spacing between the conductive connecting pieces can be kept equal to lay the conductive connecting pieces.

[0057] It should be noted that the extension direction of the fixing piece 21 is parallel to the rotation axis of the carrier 100; and the connection mode of the fixing piece 21 and the conductive connecting piece is welding or adhesion.

[0058] In the embodiment, two fixing members 21 are arranged on the conductive connecting member in the rotation direction of the carrier 100. For example, the two fixing members 21 are respectively arranged in the two first fixing spaces formed by the cooperation of the two first fixing mechanisms 13 and the corresponding second fixing mechanisms 14. Through the above arrangement, the two ends of the conductive connecting member can be fixed at the same time through the fixing of the fixing members 21, so as to avoid the two ends of the conductive connecting member from falling off from the carrier 100 after being cut off.

[0059] As an implementation manner, the fixing manner of the operation mechanism 221 to the fixing member 21 is one of adhesion and adsorption connection. Specifically, the adhesion manner between the operation mechanism 221 and the fixing member 21 is not limited in the application, and only needs to be able to separate after the operation mechanism 221 and the fixing member 21 are adhered under the action of external force; the operation mechanism 221 can be provided with an adsorption hole, and the fixing member 21 is adsorbed on the operation mechanism 221 by forming negative pressure in the adsorption hole, so as to realize the adsorption connection of the operation mechanism 221 and the fixing member 21.

[0060] As an implementation manner, the processing assembly 22 comprises a heating mechanism 222, and the heating mechanism 222 is used for fixing the conductive connecting member and the fixing member 21. Specifically, the heating mechanism 222 is arranged close to the operation mechanism 221, and the conductive connecting member and the fixing member 21 are welded through the heating mechanism 222. In some embodiments, the heating mechanism 222 is an electric heating lamp, and the fixing member 21 and the conductive connecting member are heated by the electric heating lamp to make the fixing member 21 and the conductive connecting member welded.

[0061] Alternatively, the fixing member 21 has adhesion, so that the fixing member 21 and the conductive connecting member are adhered. It can be understood that the fixing manner of the fixing member 21 and the conductive connecting member is not limited in the application, and only needs to be able to separate after the fixing member 21 and the conductive connecting member are adhered under the action of external force.

[0062] As an implementation manner, the processing assembly 22 comprises a cutting mechanism 223, and the cutting mechanism 223 is used for cutting the conductive connecting member. Specifically, the cutting mechanism 223 has a movement freedom, so that the cutting mechanism 223 has a cutting position close to the carrier 100. When the cutting mechanism 223 is in the cutting position and the two first fixing spaces fix the conductive connecting member, the cutting mechanism 223 can cut the conductive connecting member, so that the conductive connecting member has a first end and a second end fixed by the two first fixing spaces. The cutting position refers to the position of the cutting mechanism 223 when the cutting mechanism 223 cuts the conductive connecting member. In addition, the conductive connecting member is fixed by the first fixing space, so as to avoid the increase of additional conductive connecting member arrangement process caused by the scattered cutting of the conductive connecting member, thereby facilitating the improvement of the processing efficiency of the battery string.

[0063] As an implementation, the processing device 200 further comprises a moving assembly 23, which is used to move the cut conductive connector to the processing platform of the battery string. Specifically, the moving assembly 23 is movable, so that the moving assembly 23 has a working position and an initial position close to the carrier 100. The working position refers to the position of the moving assembly 23 when the moving assembly 23 is used to place the conductive connector on the processing platform of the battery string.

[0064] More specifically, when the moving assembly 23 is in the initial position, the moving assembly 23 can be fixed with one of the two second fixing mechanisms 14, so that the moving assembly 23 is fixed with the conductive connector. In some embodiments, the moving assembly 23 is magnetically connected with the second fixing mechanism 14, so that the moving assembly 23 can move the conductive connector through the second fixing mechanism 14. It should be noted that the moving assembly 23 can also be connected with the second fixing mechanism 14 through buckling, so that the moving assembly 23 can move the conductive connector. Therefore, the application does not limit the connection mode of the moving assembly 23 and the second fixing mechanism 14, as long as the moving assembly 23 can move the conductive connector through the second fixing mechanism 14.

[0065] In this embodiment, when the conductive connector is cut, the moving assembly 23 can move from the initial position to the working position, so that the moving assembly 23 moves the conductive connector to a connecting position that can be attached to the battery sheet. The connecting position refers to the position of the conductive connector when the conductive connector is placed on the processing platform of the battery string. In this way, the cut conductive connector can be automatically placed on the connecting position by the moving assembly 23, without manual laying, so as to improve the processing efficiency of the battery string.

[0066] In this application, as an implementation, the working process of the processing device 200 of the conductive connector is as follows:

[0067] First, the conductive connector is wound on the bearing surface 111, and then the two first fixing mechanisms 13 are abutted with the fixing seat 18 through the first fixing assembly 12, and then the two first fixing mechanisms 13 and the second fixing mechanism 14 are connected to form two first fixing spaces, which respectively fix the first end and the second end of the conductive connector, and the operating mechanism 221 places a fixing piece 21 in each first fixing space, and the fixing piece 21 is welded with the conductive connector through the heating mechanism 222.

[0068] Then, the cutting mechanism 223 moves to the cutting position to cut the conductive connector between the two first fixing mechanisms 13. By fixing the first end and the second end of the conductive connector through the fixing piece 21, the cut conductive connector can be prevented from being scattered, so as to improve the processing efficiency of the battery string.

[0069] After the cutting is completed, the moving assembly 23 moves to the initial position and is connected with one of the two second fixing mechanisms 14. At this time, the first fixing assembly 12 is separated from the first fixing mechanism 13.

[0070] Finally, the moving assembly 23 drives the conductive connecting piece and the fixing piece 21 to the connecting position through the second fixing mechanism 14, so as to perform the welding of the battery piece and the conductive connecting piece.

[0071] It should be understood that, for those skilled in the art, improvements or changes can be made according to the above description, and all these improvements and changes shall belong to the protection scope of the claims attached to the present application.
