Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic power generation, and in particular to a method for processing a battery string. Background Art

[0002] A battery string is an important component in solar photovoltaic power generation. A battery string is formed by welding multiple independent solar cells through conductive connectors. Among them, the conductive connectors can be connection materials such as solder tapes.

[0003] In the prior art, a set of conductive connectors is usually wound around a carrier for storage. During the processing of the battery string, the conductive connectors on the carrier are cut and then unwound and laid out so that the laid-out conductive connectors can be welded to multiple independent solar cells to form a battery string. However, since only one set of conductive connectors can be wound around one carrier, when the conductive connectors on the carrier are used up, the processing of the battery string needs to be paused, and the conductive connectors need to be rewound on the carrier or the carrier needs to be replaced with a new carrier with conductive connectors to continue the processing of the battery string, which results in a reduction in the production efficiency of the battery string.

[0004] Therefore, how to improve the production efficiency of the battery string is a technical problem that those skilled in the art urgently need to solve. Summary of the Invention

[0005] In order to solve the deficiencies of the prior art, the purpose of the present application is to provide a method for processing a battery string with high production efficiency.

[0006] To achieve the above purpose, the present application adopts the following technical solutions:

[0007] A method for processing a battery string, the processing method includes: fixing the heads and tails of multiple sets of conductive connectors; connecting the tail of each set of conductive connectors to the head of the adjacent conductive connector so that the multiple sets of conductive connectors are connected, and outputting the connected multiple sets of conductive connectors; bringing the connected multiple sets of conductive connectors into contact with and connecting to solar cells to form a battery string.

[0008] Further, define two adjacent sets of conductive connectors as a first conductive connection group and a second conductive connection group. The head and tail are respectively fixed by two fixing mechanisms. Connecting the tail of each set of conductive connectors to the head of the adjacent conductive connector includes: bringing the fixing mechanism for fixing the tail of the first conductive connection group close to the fixing mechanism for fixing the head of the second conductive connection group so that the tail of the first conductive connection group contacts the head of the second conductive connection group; welding or bonding the tail of the first conductive connection group to the head of the second conductive connection group so that the tail of the first conductive connection group is connected to and conducts with the head of the second conductive connection group.

[0009] Further, the fixing mechanism includes a first fixing member and a second fixing member. A fixing area for fixing the head end or the tail end is formed between the first fixing member and the second fixing member. At least one of the first fixing member and the second fixing member is formed with a fixing notch located in the fixing area. The fixing notch is used to limit the position of the head end or the tail end. Fixing the head ends and tail ends of multiple groups of conductive connectors includes: the first fixing member and the second fixing member fix the head end or the tail end of the conductive connector, and the head end or the tail end of the conductive connector is restricted within the fixing notch, so that the position of the head end or the tail end of the conductive connector relative to the fixing mechanism is fixed.

[0010] Further, each group of conductive connectors includes multiple solder tapes. The head end or the tail end of each solder tape is restricted within a fixing notch. Connecting the tail end of each group of conductive connectors to the head end of an adjacent group of conductive connectors includes: the fixing notches of the fixing mechanism for fixing the tail end of the first conductive connection group correspond one by one to the fixing notches of the fixing mechanism for fixing the head end of the second conductive connection group, so that the tail end of each solder tape of the first conductive connection group is correspondingly connected to the head end of each solder tape of the second conductive connection group.

[0011] Further, the fixing notch is one of a fixing groove, a fixing hole, and a fixing tooth; when the conductive connector is within the fixing area, the conductive connector is fixed in the fixing groove, the fixing hole, or the fixing tooth.

[0012] Further, each group of conductive connectors is wound around a carrier. The conductive connectors on the carrier are cut so that the conductive connectors form head ends and tail ends. The tail end of the conductive connectors on one carrier is connected to the head end of the conductive connectors on another carrier to output multiple connected groups of conductive connectors. The fixing mechanism is detachably connected to the carrier.

[0013] Further, define two cooperating carriers as a first carrier and a second carrier. The tail end of the conductive connectors on the first carrier can be connected to the head end of the conductive connectors on the second carrier. Define the fixing mechanism for fixing the tail end on the first carrier as a tail end fixing member, and the fixing mechanism for fixing the head end on the second carrier as a head end fixing member; the tail end fixing member and the head end fixing member are close to each other so that the tail end on the first carrier contacts and connects to the head end on the second carrier. The carrier has a degree of freedom of movement.

[0014] Further, the carrier is a cylindrical structure. When the first carrier is at a preset angle, the second carrier approaches the first carrier so that the tail end on the first carrier contacts and connects to the head end on the second carrier. The carrier has a degree of freedom of movement.

[0015] Further, after the conductive connectors on the first carrier are output, the tail end fixing member is separated from the first carrier, and the tail end fixing member and the head end fixing member are close to each other so that the tail end on the first carrier contacts and connects to the head end on the second carrier.

[0016] Further, conductive connectors of unit length are output on the carrier, and the output conductive connectors are brought into contact with and connected to the unit length of solar cells.

[0017] The processing method of the above battery string can output multiple groups of connected conductive connectors without interrupting the production of the battery string, which is beneficial to improving the production efficiency of the battery string. Description of the Drawings

[0028] As Figures 1 to 3 shown, this application provides a processing device 100 for a battery string. The processing device 100 includes a plurality of carriers 11, a fixing mechanism 12, a connecting mechanism 13 and a moving mechanism 14. Among them, each carrier 11 is capable of winding a set of conductive connectors 20.

[0029] Specifically, each set of conductive connectors 20 is wound around a carrier 11, and each carrier 11 has a rotational degree of freedom. The fixing mechanism 12 is detachably connected to the carrier 11. Two fixing mechanisms 12 are provided on each carrier 11, and the two fixing mechanisms 12 are respectively used to fix the head end 21 and the tail end 22 of the conductive connectors 20 on the corresponding carrier 11. The connecting mechanism 13 is used to connect the conductive connectors 20 on the plurality of carriers 11. When the fixing mechanism 12 is separated from the corresponding carrier 11, the moving mechanism 14 is used to drive the separated fixing mechanism 12 and the conductive connectors 20 on the corresponding carrier 11 to move, so that the conductive connectors 20 on the corresponding carrier 11 are laid.

[0030] Specifically, the two fixing mechanisms 12 of each carrier 11 are respectively defined as a first fixing mechanism 121 and a second fixing mechanism 122. Among them, the first fixing mechanism 121 is used to fix the head end 21 of the conductive connector 20, and the second fixing mechanism 122 is used to fix the tail end 22 of the conductive connector 20.

[0031] More specifically, when the moving mechanism 14 drives the conductive connection member 20 fixed by the first fixing mechanism 121 on a carrier 11 to move for laying, the tail end 22 fixed by the second fixing mechanism 122 on the carrier 11 contacts the head end 21 on the conductive connection member 20 on another carrier 11. At this time, the connection mechanism 13 connects the contact points of the two sets of conductive connection members 20, thereby realizing the connection of the two sets of conductive connection members 20. To realize the connection of the tail end 22 of the conductive connection member 20 on one carrier 11 and the head end 21 of the conductive connection member 20 on another carrier 11, so that the processing device 100 can output multiple sets of connected conductive connection members 20.

[0032] Through the above settings, it is possible to avoid interrupting the processing of the battery string to supply the conductive connection member 20 after a set of conductive connection members 20 is used up, thereby enabling continuous supply of the conductive connection member 20, which is beneficial to improving the production efficiency of the battery string.

[0033] In this application, the conductive connection member 20 is a welding tape, and the independent battery cells can be welded into a battery string through the welding tape. The conductive connection member 20 on the cutting carrier 11 is cut so that the conductive connection member 20 has a head end 21 and a tail end 22. The tail end 22 of the conductive connection member 20 on one carrier 11 is connected to the head end 21 of the conductive connection member 20 on another carrier 11 to output multiple sets of connected conductive connection members 20.

[0034] As an implementation manner, two cooperating carriers 11 are defined as a first carrier 111 and a second carrier 112. Among them, the tail end 22 of the conductive connection member 20 on the first carrier 111 can be connected to the head end 21 of the conductive connection member 20 on the second carrier 112, so that the two sets of conductive connection members 20 on the first carrier 111 and the second carrier 112 are connected. The fixing mechanism 12 for fixing the tail end 22 on the first carrier 111 is defined as a tail end fixing member 127, that is, the second fixing mechanism 122 on the first carrier 111 is the tail end fixing member 127; the fixing mechanism 12 for fixing the head end 21 on the second carrier 112 is a head end fixing member 128, that is, the first fixing mechanism 121 on the second carrier 112 is the head end fixing member 128.

[0035] The tail end fixing member 127 is close to the head end fixing member 128, so that the tail end 22 on the first carrier 111 contacts the head end 21 on the second carrier 112 and is connected by the connection mechanism 13, thereby realizing the connection between the two sets of conductive connection members 20 on the first carrier 111 and the second carrier 112.

[0036] In this embodiment, the carrier 11 has a degree of freedom of movement, so as to avoid interference between the first carrier 111 and the second carrier 112, which is conducive to the rapid replacement of the carrier 11 by the processing equipment 100, and further conducive to the connection of the conductive connectors 20 between adjacent carriers 11, thereby further improving the production efficiency of the battery string.

[0037] As an alternative implementation, the carrier 11 is a cylindrical structure. When the first carrier 111 rotates by a preset angle, the second carrier 112 approaches the first carrier 111. At this time, the tail-end fixing member 127 and the head-end fixing member 128 approach each other, so that the tail end 22 on the first carrier 111 contacts and connects with the head end 21 on the second carrier 112.

[0038] Exemplarily, the preset angle can be 180° or 270° or other angles. When the first carrier 111 rotates by the preset angle, the tail-end fixing member 127 can approach the head-end fixing member 128, which is conducive to realizing the connection of the two sets of conductive connectors 20 on the first carrier 111 and the second carrier 112.

[0039] As another embodiment, after the output of the conductive connector 20 on the first carrier 11 is completed, the tail-end fixing member 127 is separated from the first carrier 111, and the tail-end fixing member 127 and the head-end fixing member 128 approach each other, so that the tail end 22 on the first carrier 111 contacts and is connected to the head end 21 on the second carrier 112 through the connecting mechanism 13. With such a setting, when the moving mechanism 14 drives the conductive connector 20 on the first carrier 111 to complete the laying, the tail-end fixing member 127 can follow the conductive connector 20 and be separated from the first carrier 111. At this time, the first carrier 111 can be moved to avoid the first carrier 111 without the conductive connector 20 interfering with the feeding of the second carrier 112, which is conducive to improving the feeding efficiency of the conductive connector 20, thereby further improving the processing efficiency of the battery string.

[0040] In summary, in this application, it can be that after the moving mechanism 14 lays the conductive connector 20 on the first carrier 111 as a whole, the tail-end fixing member 127 on the first carrier 111 and the head-end fixing member 128 on the second carrier 112 approach each other, so that the two sets of conductive connectors 20 are connected; or it can be that during the process of the moving mechanism 14 driving the conductive connector 20 on the first carrier 111 to be laid, after the first carrier 111 rotates by a preset angle, the tail-end fixing member 127 on the first carrier 111 and the head-end fixing member 128 on the second carrier 112 approach each other, so that the two sets of conductive connectors 20 are connected. Therefore, this application does not limit the connection time of the conductive connector 20 on the first carrier 111 and the conductive connector 20 on the second carrier 112, and only needs to satisfy that the two sets of conductive connectors 20 can be connected.

[0041] As an implementation manner, the processing device 100 further includes a connecting member 16. When the tail-end fixing member 127 on the first carrier 111 approaches the head-end fixing member 128 on the second carrier 112, the connecting member 16 is used to fix the relative positions of the tail-end fixing member 127 and the head-end fixing member 128, so as to prevent relative movement between the tail-end fixing member 127 and the head-end fixing member 128 from causing connection offset of the conductive connecting members 20 on the first carrier 111 and the conductive connecting members 20 on the second carrier 112, which is beneficial to improving the connection accuracy of the two groups of conductive connecting members 20.

[0042] As an implementation manner, a limiting structure (not shown in the figure) is provided on the connecting member 16. The limiting structure is used to limit the positions of the tail-end fixing member 127 and the head-end fixing member 128 on the connecting member 16, so that when the connecting member 16 fixes the positions of the tail-end fixing member 127 and the head-end fixing member 128, the relative positions of the tail-end fixing member 127 and the head-end fixing member 128 can be further restricted, and further the connection accuracy of the two groups of conductive connecting members 20 can be improved.

[0043] Exemplarily, the connecting member 16 can be a robotic arm. When the tail-end fixing member 127 on the first carrier 111 approaches the head-end fixing member 128 on the second carrier 112, the positions of the tail-end fixing member 127 and the head-end fixing member 128 can be fixed by the robotic arm.

[0044] Exemplarily, the limiting structure can be a limiting groove provided on the robotic arm. The limiting groove is adapted to the tail-end fixing member 127 or the head-end fixing member 128, so that when the robotic arm fixes the tail-end fixing member 127 and the head-end fixing member 128, the relative position of the tail-end fixing member 127 and the robotic arm, and the relative position of the head-end fixing member 128 and the robotic arm can be restricted through the limiting groove, thereby improving the position accuracy of fixing the tail-end fixing member 127 and the head-end fixing member 128 by the connecting member 16, and further improving the connection accuracy of the two groups of conductive connecting members 20.

[0045] Exemplarily, the limiting structure on the connecting member 16 can limit the head end 21 and the tail end 22 of the conductive connecting member 20, so that the tail end 22 on the tail-end fixing member 127 and the head end 21 of the head-end fixing member 128 are in one-to-one correspondence, thereby improving the connection accuracy of the conductive connecting member 20.

[0046] As an implementation manner, the connecting mechanism 13 can be an electric heating wire. The electric heating wire is arranged in the fixing mechanism 12, so that the electric heating wire can heat the fixing mechanism 12, and heat the conductive connecting member 20 through the fixing mechanism 12, so that the contact parts of the two groups of conductive connecting members 20 are welded by heating, thereby realizing the connection between the two groups of conductive connecting members 20.

[0047] As another implementation, the connecting mechanism 13 can be an electric heating lamp disposed at the contact of the two sets of conductive connectors 20. The connection part is irradiated by the electric heating lamp so that the contact of the two sets of conductive connectors 20 is welded by heating, thereby realizing the connection between the two sets of conductive connectors 20.

[0048] As another implementation, the connecting mechanism 13 can be a nozzle capable of spraying glue disposed at the contact of the two sets of conductive connectors 20. The nozzle faces the contact of the two sets of conductive connectors 20 to bond the two sets of conductive connectors 20. Exemplarily, the nozzle sprays conductive glue so that the connecting mechanism 13 can spray conductive glue toward the contact of the two sets of conductive connectors 20, thereby bonding the two sets of conductive connectors 20 through the conductive glue, and the conductive glue is beneficial to the conduction between the two sets of conductive connectors 20.

[0049] As another implementation, the head ends 21 and the tail ends 22 of each set of conductive connectors 20 are coated with a viscous material so that the contact of the two sets of conductive connectors 20 is bonded by the viscous material. Exemplarily, the viscous material can be conductive glue.

[0050] It should be noted that the present application does not limit the setting form and the setting position of the connecting mechanism 13, and only needs to satisfy that the connecting mechanism 13 can connect the contacts of the two sets of conductive connectors 20.

[0051] Such as Figure 4 and Figure 5 As shown, as an implementation, the fixing mechanism 12 includes a first fixing member 123 and a second fixing member 124. A fixing area 125 for fixing the head end 21 or the tail end 22 is formed between the first fixing member 123 and the second fixing member 124. Specifically, at least one of the first fixing member 123 and the second fixing member 124 is formed with a fixing notch 126 located in the fixing area 125, and the fixing notch 126 is used to limit the position of the head end 21 or the tail end 22. With such a setting, the position of the conductive connector 20 can be limited by the fixing notch 126, avoiding the misalignment of the conductive connector 20 when the two sets of conductive connectors 20 are connected, which is beneficial to improving the connection accuracy between the two sets of conductive connectors 20.

[0052] As an implementation, each set of conductive connectors 20 includes a plurality of solder tapes, and the head end 21 or the tail end 22 of each solder tape is restricted within a fixing notch 126. With such a setting, when the two sets of conductive connectors 20 are connected, each solder tape on the two sets of conductive connectors 20 can be made to correspond one by one through the fixing notch 126, thereby further improving the connection accuracy between the two sets of conductive connectors 20.

[0053] As an alternative implementation, the fixed notch 126 is one of a fixed groove, a fixed hole, and a fixed tooth; when the conductive connector 20 is within the fixed area 125, the conductive connector 20 is fixed in the fixed groove, the fixed hole, or the fixed tooth. In this application, the conductive connector 20 can be a circular welding tape, a triangular welding tape, etc. With such a setting, fixed notches 126 of different shapes can be adapted to conductive connectors 20 of different shapes. For example, when the conductive connector 20 is a circular welding tape, the fixed notch 126 is a fixed hole, thereby improving the adaptability between the fixed notch 126 and the conductive connector 20, which is beneficial to improving the connection tightness between the fixed notch 126 and the conductive connector 20, and further improving the connection stability between the fixing mechanism 12 and the conductive connector 20, avoiding the conductive connector 20 from shaking in the fixing mechanism 12 and causing inaccurate connection between the two groups of conductive connectors 20, and further improving the connection accuracy between the two groups of conductive connectors 20.

[0054] Exemplarily, the first fixing member 123 and the second fixing member 124 are magnetically connected to facilitate quick disassembly and assembly between the fixing mechanism 12 and the conductive connector 20, and further improve the production efficiency of the battery string. The first fixing member 123 and the second fixing member 124 can also be fixed by welding to improve the connection stability between the first fixing member 123 and the second fixing member 124, thereby improving the connection stability between the fixing mechanism 12 and the conductive connector 20. After the conductive connector 20 is laid, the fixing mechanism 12 can be cut and separated. Therefore, this application does not limit the fixing method of the first fixing member 123 and the second fixing member 124.

[0055] Exemplarily, the first fixing member 123 and / or the second fixing member 124 are magnetically connected to the carrier 11 to enable the fixing mechanism 12 to be detachably connected to the carrier 11. With such a setting, a magnetic force can be formed between the fixing mechanism 12 and the carrier 11, enabling the fixing mechanism 12 to be adsorbed on the carrier 11, so that the fixing mechanism 12 can rotate synchronously with the carrier 11. When the force applied by the moving mechanism 14 to the fixing mechanism 12 is greater than the magnetic force between the fixing mechanism 12 and the carrier 11, the fixing mechanism 12 can be separated from the carrier 11, enabling the moving mechanism 14 to drive the fixing mechanism 12 to move, thereby driving the conductive connector 20 connected to the fixing mechanism 12 to move, and further realizing the laying of the conductive connector 20, which is beneficial to the processing of the battery string. It should be noted that this application does not limit the detachable connection method between the fixing mechanism 12 and the carrier 11. In addition, this application is described by taking the magnetic connection between the fixing mechanism 12 and the carrier 11 as an example.

[0056] Exemplarily, the moving mechanism 14 can be a robotic arm, which can grasp the fixing mechanism 12 on the carrier 11 to separate the fixing mechanism 12 from the carrier 11, and the robotic arm can drive the fixing mechanism 12 to move, so as to lay the conductive connection member 20.

[0057] As Figure 1 shown, as an implementation manner, the processing device 100 further includes a processing platform 15, and at least one battery cell is placed on the processing platform 15. Specifically, the moving mechanism 14 drives the first fixing mechanism 121 to move, so that the conductive connection member 20 can be laid on the processing platform 15, so that the conductive connection member 20 contacts the battery cell.

[0058] Specifically, a heating mechanism (not shown in the figure) is provided on the processing platform 15, and the heating mechanism is used to heat the conductive connection member 20 laid on the processing platform 15, so that the battery cell and the conductive connection member 20 are welded.

[0059] Exemplarily, the heating mechanism can be an electric heating wire disposed in the processing platform 15. By heating the processing platform 15 through the electric heating wire, the battery cell and the conductive connection member 20 can be heated through heat transfer, so that the battery cell and the conductive connection member 20 are welded. The heating mechanism can also be a heating lamp disposed on the processing platform 15. The heating lamp irradiates the connection part of the battery cell and the conductive connection member 20, so that the battery cell and the conductive connection member 20 can be heated, so that the battery cell and the conductive connection member 20 are connected. Therefore, the present application does not limit the setting form and setting position of the heating mechanism.

[0060] More specifically, a plurality of processing platforms 15 are provided, and each processing platform 15 has a moving degree of freedom. After the battery cell on one processing platform 15 is connected to the conductive connection member 20, the processing platform 15 moves, so that the battery cell on another processing platform 15 can continue to be connected to the conductive connection member 20. With such a setting, when the processing device 100 can output multiple groups of connected conductive connection members 20, the processing platform 15 can continuously provide battery cells, thereby avoiding the interruption of battery string processing due to untimely supply of battery cells. The plurality of processing platforms 15 can further improve the feeding efficiency of battery cells, thereby further improving the processing efficiency of battery strings.

[0061] As an implementation manner, the processing device 100 further includes a pressing mechanism 17, and the pressing mechanism 17 is used to press the conductive connection member 20 and the battery cell. Specifically, when the conductive connection member 20 is laid on the processing platform 15, the conductive connection member 20 and the battery cell are pressed by the pressing mechanism 17 to improve the fitting tightness between the conductive connection member 20 and the battery cell, so that when the heating mechanism heats the battery cell and the conductive connection member 20, the welding efficiency of the battery cell and the conductive connection member 20 can be improved, thereby improving the production efficiency of the battery string.

[0062] As an implementation manner, conductive connectors 20 of a unit length are output on the carrier 11, and the output conductive connectors 20 are brought into contact with and connected to the unit-length solar cells. With such a setting, unit-length solar cells can be placed on the processing platform 15, so that when the moving mechanism 14 lays the conductive connectors 20 of the unit length, the conductive connectors 20 of the unit length can be connected to the unit-length solar cells, so as to avoid an excessive or insufficient number of solar cells connected to the conductive connectors 20, thereby improving the production quality of the battery strings of the processing device 100.

[0063] It should be noted that along the extending direction of the conductive connectors 20 laid on the processing platform 15, the unit length can be the total length of one or more solar cells placed on the processing platform 15, so as to realize the connection between single or multiple solar cells and the conductive connectors 20.

[0064] As Figure 6 shown, the present application also provides a method for processing battery strings, and the processing method includes the following steps:

[0065] S1: Fix the first ends 21 and the second ends 22 of multiple groups of conductive connectors 20.

[0066] Specifically, each group of conductive connectors 20 is wound around a carrier 11, and the conductive connectors 20 on the carrier 11 are cut so that the conductive connectors 20 are formed with first ends 21 and second ends 22. Two fixing mechanisms 12 are arranged on each carrier 11, and the two fixing mechanisms 12 respectively fix the first ends 21 and the second ends 22 of the conductive connectors 20 on the carrier 11.

[0067] More specifically, the two fixing mechanisms 12 are respectively a first fixing mechanism 121 and a second fixing mechanism 122. The first fixing mechanism 121 fixes the first ends 21 of the conductive connectors 20, and the second fixing mechanism 122 fixes the second ends 22 of the conductive connectors 20.

[0068] Further, in step S1, the first fixing member 123 and the second fixing member 124 fix the first ends 21 or the second ends 22 of the conductive connectors 20, and the first ends 21 or the second ends 22 of the conductive connectors 20 are restricted within the fixing notches 126, so that the positions of the first ends 21 or the second ends 22 of the conductive connectors 20 relative to the fixing mechanisms 12 are fixed. The conductive connectors 20 can be limited by the fixing notches 126, thereby improving the connection stability between the conductive connectors 20 and the fixing mechanisms 12.

[0069] It should be noted that in this application, the carrier 11 may not be used. That is, the head end 21 and the tail end 22 of the conductive connection member 20 of this application only need to be fixed by two fixing mechanisms 12 respectively. Then, by bringing the two fixing mechanisms 12 closer to each other, the contact between the head end 21 and the tail end 22 is realized, and further the connection between the head end 21 and the tail end 22 is realized.

[0070] It should be noted that in step S1, the first fixing member 123 and the second fixing member 124 fix the head end 21 or the tail end 22 of the conductive connection member 20, and the head end 21 or the tail end 22 of the conductive connection member 20 is restricted within the fixing notch 126, so that the position of the head end 21 or the tail end 22 of the conductive connection member 20 relative to the fixing mechanism 12 is fixed.

[0071] S2: The tail end 22 of each group of conductive connection members 20 is connected to the head end 21 of the adjacent conductive connection member 20, so that multiple groups of conductive connection members 20 are connected, and the connected multiple groups of conductive connection members 20 are output.

[0072] Specifically, two cooperating carriers 11 are defined as a first carrier 111 and a second carrier 112. The moving mechanism 14 drives the first fixing mechanism 121 on the first carrier 111 to move, so as to realize the output of the conductive connection member 20 on the first carrier 111. The fixing mechanism 12 for fixing the tail end 22 on the first carrier 111 is defined as the tail end fixing member 127, that is, the second fixing mechanism 122 on the first carrier 111 is the tail end fixing member 127; the fixing mechanism 12 for fixing the head end 21 on the second carrier 112 is the head end fixing member 128, that is, the first fixing mechanism 121 on the second carrier 112 is the head end fixing member 128. The tail end fixing member 127 on the first carrier 111 can approach the head end fixing member 128 on the second carrier 112, so that the conductive connection members 20 on the first carrier 111 and the second carrier 112 are in contact, and the conductive connection member 20 on the first carrier 111 and the conductive connection member 20 on the second carrier 112 are connected through the connection mechanism 13, so as to realize the connection of two groups of conductive connection members 20, thereby realizing the connection between multiple groups of conductive connection members 20, and further enabling the processing device 100 to output multiple groups of connected conductive connection members 20 without interrupting the production of the battery string, which is beneficial to improving the production efficiency of the battery string.

[0073] It should be noted that the output of the conductive connection member 20 may also not require the carrier 11. Only the head end 21 of the conductive connection member 20 is output through the first fixing mechanism 121, and the tail end 22 of the conductive connection member 20 is connected to the head end 21 of another group of conductive connection members 20 on another first fixing mechanism 121.

[0074] S3: The connected multiple groups of conductive connection members 20 are brought into contact with and connected to the battery wafers to form a battery string.

[0075] Specifically, the moving mechanism 14 can drive the first fixing mechanism 121 on the first carrier 111 to move, so as to drive the conductive connecting member 20 on the first carrier 111 to be laid on the processing platform 15, so that the conductive connecting member 20 contacts the battery cell, and the battery cell and the conductive connecting member 20 are welded through the heating mechanism to realize the processing of the battery string.

[0076] As Figure 7 shown, two adjacent groups of conductive connecting members 20 are defined as the first conductive connection group and the second conductive connection group, and the head ends 21 and the tail ends 22 of the first conductive connection group and the second conductive connection group are respectively fixed by two fixing mechanisms 12. Then step S2 includes:

[0077] S21: Move the fixing mechanism 12 for fixing the tail end 22 of the first conductive connection group closer to the fixing mechanism 12 for fixing the head end 21 of the second conductive connection group, so that the tail end 22 of the first conductive connection group contacts the head end 21 of the second conductive connection group.

[0078] Specifically, taking the example that the conductive connecting member 20 is wound around the carrier 11. The first conductive connection group is wound around the first carrier 111, and the second conductive connection group is wound around the second carrier 112. The first fixing mechanism 121 on the second carrier 112 is close to the second fixing mechanism 122 on the first carrier 111, so that the head end 21 of the second conductive connection group on the second carrier 112 is close to the tail end 22 of the first conductive connection group on the first carrier 111, and the positions of the second fixing mechanism 122 on the first carrier 111 and the first fixing mechanism 121 on the second carrier 112 are fixed by the connecting member 16, so as to realize the contact between the tail end 22 of the first conductive connection group and the head end 21 of the second conductive connection group.

[0079] More specifically, in step S21, the fixing notches 126 of the fixing mechanism 12 for fixing the tail end 22 of the first conductive connection group correspond to the fixing notches 126 of the fixing mechanism 12 for fixing the head end 21 of the second conductive connection group one by one, so that the tail end 22 of each solder strip of the first conductive connection group is correspondingly connected to the head end 21 of each solder strip of the second conductive connection group. By restricting the position of the first conductive connection group relative to the second fixing mechanism 122 on the first carrier 111 and the position of the second conductive connection group relative to the first fixing mechanism 121 on the second carrier 112 through the fixing notches 126, and cooperating with the limiting structure on the connecting member 16 to limit the second fixing mechanism 122 on the first carrier 111 and the first fixing mechanism 121 on the second carrier 112, the connection accuracy of the solder strips between the first conductive connection group and the second conductive connection group can be further improved, and the production efficiency of the battery string can be further improved.

[0080] S22: Weld or bond the tail end 22 of the first conductive connection group to the head end 21 of the second conductive connection group, so that the tail end 22 of the first conductive connection group is connected and electrically conductive to the head end 21 of the second conductive connection group.

[0081] Specifically, heat weld or glue bond the contact between the tail end 22 of the first conductive connection group and the head end 21 of the second conductive connection group through the connecting mechanism 13. So that the first conductive connection group and the second conductive connection group are connected, thereby enabling the processing device 100 to continuously output the first conductive connection group and the second conductive connection group, so as to improve the production efficiency of the battery string.

[0082] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations shall fall within the protection scope of the appended claims of this application.
