[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0042] It should be noted that the words "first", "second" and similar words used in the specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "an" do not indicate a quantity limitation, but indicate the existence of at least one. "Multiple" or "several" means at least two. Words such as "include" or "comprise" mean that the elements or objects appearing before "include" or "comprises" include the elements or objects listed after "include" or "comprises" and their equivalents, and do not exclude other elements or objects. Words such as "connected" or "connected" and similar words are not limited to physical or mechanical connections, and may include electrical connections, whether direct or indirect.

[0043] The singular forms "a", "an", and "the" used in this specification and the appended claims are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0044] like Figure 1 and Figure 2As shown, the present application provides a carrier 100, which is used to wind a conductive connector 200. In the present application, the conductive connector 200 is a welding strip, through which independent battery cells can be welded, so that the independent battery cells are welded to form a battery string. It can be understood that the conductive connector 200 can be a circular welding strip, a triangular welding strip, etc., and the present application does not limit the structural form of the conductive connector 200.

[0045] It should be noted that the number of the conductive connectors 200 can be adjusted according to actual needs, and the conductive connectors 200 are wound on the carrier 100 at equal intervals, so that the conductive connectors 200 are also laid at equal intervals.

[0046] Specifically, the carrier 100 has a rotational degree of freedom, and the carrier 100 has a winding surface 12 for winding the conductive connector 200, and the winding surface 12 is arranged around the rotation axis of the carrier 100. The winding direction of the conductive connector 200 is consistent with the rotation direction of the carrier 100, or the winding direction of the conductive connector 200 is opposite to the rotation direction of the carrier 100, which is not limited in the present application.

[0047] More specifically, in order to better reflect the implementation of the present application, the present application takes the carrier 100 as an example of being substantially cylindrical. It should be noted that the carrier 100 may also be a prism, a cylinder, or the like, and the present application does not limit this, and only requires that the carrier 100 has rotational freedom.

[0048] As an implementation, the carrier 100 includes a first fixing mechanism 13 and a second fixing mechanism 14, the first fixing mechanism 13 is located on the carrier 100 and is detachably fixed to the carrier 100, and the second fixing mechanism 14 is connected with the first fixing mechanism 13 to form a first fixing space for fixing the conductive connector 200. Through the above arrangement, the first fixing mechanism 13 and the second fixing mechanism 14 can be distributed on both sides of the conductive connector 200 along the radial direction of the carrier 100, so that the conductive connector 200 is located between the first fixing mechanism 13 and the second fixing mechanism 14, which is conducive to the fixing of the conductive connector 200 by the first fixing mechanism 13 and the second fixing mechanism 14. Among them, the first fixing space refers to the space between the first fixing mechanism 13 and the second fixing mechanism 14 for clamping the conductive connector 200. In addition, the detachable fixing of the first fixing mechanism 13 and the carrier 100 can enable the first fixing mechanism 13 to be fixed or separated from the carrier 100, which is conducive to the subsequent processing of the conductive connector 200, thereby improving the processing efficiency of the battery string.

[0049] As an optional implementation, the carrier 100 includes a third fixing mechanism 15 and a fourth fixing mechanism 16, the first fixing mechanism 13 and the third fixing mechanism 15 are distributed on the carrier 100 along the rotation direction of the carrier 100, the third fixing mechanism 15 can be detachably fixed to the carrier 100, and the third fixing mechanism 15 and the fourth fixing mechanism 16 are connected in cooperation to form a second fixing space for fixing the conductive connector 200. Specifically, the second fixing mechanism 14 and the fourth fixing mechanism 16 are both located on the carrier 100, and the second fixing mechanism 14 and the fourth fixing mechanism 16 are distributed on the carrier 100 along the rotation direction of the carrier 100, so that the first fixing mechanism 13 and the second fixing mechanism 14 can cooperate to fix the conductive connector 200, and the third fixing mechanism 15 and the fourth fixing mechanism 16 can cooperate to fix the conductive connector 200. In addition, the detachable fixation of the third fixing mechanism 15 with the carrier 100 can enable the third fixing mechanism 15 to be fixed or separated from the carrier 100, which is beneficial to the subsequent processing of the conductive connector 200, thereby improving the processing efficiency of the battery string.

[0050] like Figure 3 and Figure 4 As shown, the carrier 100 has a receiving groove 11, and the receiving groove 11 has at least one opening located on the winding surface 12. At this time, the first fixing mechanism 13 is located in the receiving groove 11 and is detachably fixed to the receiving groove 11, and the second fixing mechanism 14 is located outside the receiving groove 11, and the second fixing mechanism 14 and the first fixing mechanism 13 form a first fixing space for fixing the conductive connector 200. Through the above arrangement, the first fixing mechanism 13 and the second fixing mechanism 14 can be distributed on both sides of the conductive connector 200 along the radial direction of the carrier 100, so that the conductive connector 200 is located between the first fixing mechanism 13 and the second fixing mechanism 14, which is conducive to the fixing of the conductive connector 200 by the first fixing mechanism 13 and the second fixing mechanism 14. Among them, the first fixing space refers to the space between the first fixing mechanism 13 and the second fixing mechanism 14 for clamping the conductive connector 200. In addition, the detachable fixation of the first fixing mechanism 13 and the receiving groove 11 can enable the first fixing mechanism 13 to be fixed to or separated from the receiving groove 11, thereby facilitating subsequent processing of the conductive connector 200 and further improving the processing efficiency of the battery string.

[0051] As an optional implementation, in the case where the carrier 100 has a receiving slot 11, the first fixing mechanism 13 and the third fixing mechanism 15 are distributed in the receiving slot 11 along the rotation direction of the carrier 100, the third fixing mechanism 15 can be detachably fixed to the receiving slot 11, the fourth fixing mechanism 16 is located outside the receiving slot 11, and a second fixing space for fixing the conductive connector 200 is formed between the third fixing mechanism 15 and the fourth fixing mechanism 16. Specifically, the second fixing mechanism 14 and the fourth fixing mechanism 16 are both located outside the receiving slot 11, and the second fixing mechanism 14 and the fourth fixing mechanism 16 are distributed outside the receiving slot 11 along the rotation direction of the carrier 100, so that the first fixing mechanism 13 and the second fixing mechanism 14 can cooperate to fix the conductive connector 200, and the third fixing mechanism 15 and the fourth fixing mechanism 16 can cooperate to fix the conductive connector 200. In addition, the detachable fixation of the third fixing mechanism 15 and the receiving groove 11 can enable the third fixing mechanism 15 to be fixed to or separated from the receiving groove 11, thereby facilitating subsequent processing of the conductive connector 200 and further improving the processing efficiency of the battery string.

[0052] In this embodiment, the first fixing mechanism 13 is bonded to the receiving groove 11. It should be noted that the present application does not limit the bonding method between the first fixing mechanism 13 and the receiving groove 11, and it is only required that the first fixing mechanism 13 and the receiving groove 11 can be separated under the action of external force after bonding.

[0053] Or the first fixing mechanism 13 is connected to the receiving groove 11 by magnetism. Exemplarily, the first fixing mechanism 13 can be set as a magnet, and a magnet can be provided in the receiving groove 11, so that the magnetic connection between the first fixing mechanism 13 and the receiving groove 11 is achieved by the attraction of two magnet parts. Exemplarily, the first fixing mechanism 13 can be set as a metal part, and a magnet can be provided in the receiving groove 11, so that the magnetic connection between the first fixing mechanism 13 and the receiving groove 11 is achieved by the property that the magnet can attract the metal part. Exemplarily, the first fixing mechanism 13 can be set as a magnet, and a metal part can be provided in the receiving groove 11, so that the magnetic connection between the first fixing mechanism 13 and the receiving groove 11 is achieved by the property that the magnet can attract the metal part. It should be noted that the magnet of the present application can be an electromagnet, so that the magnetic connection between the first fixing mechanism 13 and the receiving groove 11 can be maintained or disconnected by powering on or off the electromagnet, which is conducive to improving the convenience of connection or separation between the first fixing mechanism 13 and the receiving groove 11.

[0054] Or the first fixing mechanism 13 is adsorbed into the receiving groove 11. Specifically, an adsorption hole may be provided in the receiving groove 11, and negative pressure is formed in the adsorption hole so that the first fixing mechanism 13 can be adsorbed into the receiving groove 11. Through the above arrangement, an adsorption connection can be formed between the first fixing mechanism 13 and the receiving groove 11, which can help improve the convenience of connection or separation between the first fixing mechanism 13 and the receiving groove 11.

[0055] In this embodiment, the third fixing mechanism 15 is bonded to the receiving groove 11, or the third fixing mechanism 15 is connected to the receiving groove 11 by magnetism, or the third fixing mechanism 15 is adsorbed into the receiving groove 11. Among them, the bonding of the third fixing mechanism 15 to the receiving groove 11 is the same as the bonding of the first fixing mechanism 13 to the receiving groove 11, the magnetic connection of the third fixing mechanism 15 to the receiving groove 11 is the same as the magnetic connection of the first fixing mechanism 13 to the receiving groove 11, and the adsorption connection of the third fixing mechanism 15 to the receiving groove 11 is the same as the adsorption connection of the first fixing mechanism 13 to the receiving groove 11, so it is not repeated in this application.

[0056] like Figure 5 and Figure 6 As shown, when the conductive connector 200 is cut, the conductive connector 200 will be formed with a first end 21 and a second end 22, that is, the conductive connector 200 will form two ends. Through the above arrangement, the first fixing mechanism 13 and the second fixing mechanism 14 can fix the first end 21 of the conductive connector 200, and the third fixing mechanism 15 and the fourth fixing mechanism 16 can fix the second end 22 of the conductive connector 200, so that the first and second ends of the conductive connector 200 are fixed respectively, thereby preventing the first end 21 and the second end 22 of the conductive connector 200 from being separated from the carrier 100 after being cut off, so as to facilitate the subsequent processing of the conductive connector 200 and improve the processing efficiency of the battery string.

[0057] In this embodiment, the second fixing mechanism 14 is bonded to the first fixing mechanism 13, or the second fixing mechanism 14 is connected to the first fixing mechanism 13 by magnetism. The bonding between the second fixing mechanism 14 and the first fixing mechanism 13 is the same as the bonding between the first fixing mechanism 13 and the receiving groove 11, and the magnetic connection between the second fixing mechanism 14 and the first fixing mechanism 13 is the same as the magnetic connection between the first fixing mechanism 13 and the receiving groove 11, which will not be described in detail in this application. It should be noted that when the second fixing mechanism 14 is bonded to the first fixing mechanism 13, the viscosity between the second fixing mechanism 14 and the first fixing mechanism 13 is greater than the viscosity between the first fixing mechanism 13 and the receiving groove 11, or the viscosity between the second fixing mechanism 14 and the first fixing mechanism 13 is greater than the magnetic attraction between the first fixing mechanism 13 and the receiving groove 11; when the second fixing mechanism 14 and the first fixing mechanism 13 are magnetically connected, the magnetic attraction between the second fixing mechanism 14 and the first fixing mechanism 13 is greater than the viscosity between the first fixing mechanism 13 and the receiving groove 11, or the magnetic attraction between the second fixing mechanism 14 and the first fixing mechanism 13 is greater than the magnetic attraction between the first fixing mechanism 13 and the receiving groove 11, so that after the second fixing mechanism 14 and the first fixing mechanism 13 are connected in cooperation, one end of the conductive connecting member 200 is fixed between the second fixing mechanism 14 and the first fixing mechanism 13, and the second fixing mechanism 14 and the first fixing mechanism 13 are moved together under the drive of an external force to drive the conductive connecting member 200 to transfer.

[0058] In this embodiment, the fourth fixing mechanism 16 is bonded to the third fixing mechanism 15, or the fourth fixing mechanism 16 is connected to the third fixing mechanism 15 by magnetic connection. Among them, the bonding of the fourth fixing mechanism 16 and the third fixing mechanism 15 is the same as the bonding of the second fixing mechanism 14 and the first fixing mechanism 13, and the magnetic connection of the fourth fixing mechanism 16 and the third fixing mechanism 15 is the same as the magnetic connection of the second fixing mechanism 14 and the first fixing mechanism 13, which will not be repeated in this application. Through the above arrangement, the fourth fixing mechanism 16 and the third fixing mechanism 15 are used to cooperate with the second fixing mechanism 14 and the first fixing mechanism 13. When the second fixing mechanism 14 and the first fixing mechanism 13 fix and transfer the first end 21 of the conductive connector 200, the carrier 100 rotates. At this time, the fourth fixing mechanism 16 and the third fixing mechanism 15 are only for fixing the second end 22 of the conductive connector 200. Before the conductive connector 200 is completely separated from the carrier 100, the fourth fixing mechanism 16 and the third fixing mechanism 15 can be separated from the carrier 100 under the pull of external force.

[0059] It should be noted that, when the carrier 100 does not have the accommodating groove 11, the first fixing mechanism 13 is bonded to the carrier 100, or the first fixing mechanism 13 is magnetically connected to the carrier 100, or the first fixing mechanism 13 is adsorbed onto the carrier 100; the third fixing mechanism 15 is bonded to the carrier 100, or the third fixing mechanism 15 is magnetically connected to the carrier 100, or the third fixing mechanism 15 is adsorbed onto the carrier 100.

[0060] It should be noted that the connection between the first fixing mechanism 13 and the carrier 100 is the connection between the first fixing mechanism 13 and the winding surface 12 , and the connection between the third fixing mechanism 15 and the carrier 100 is the connection between the third fixing mechanism 15 and the winding surface 12 .

[0061] like Figure 7 As shown, as another optional implementation, a press mechanism 17 for cooperating with the first fixing mechanism 13 and the second fixing mechanism 14 to fix the conductive connector 200 is provided on the carrier 100, that is, in this embodiment, there is no need to arrange the third fixing mechanism 15 and the fourth fixing mechanism 16. Among them, the first fixing mechanism 13 and the second fixing mechanism 14 are used to fix the first end 21 of the conductive connector 200 after being cut, and the press mechanism 17 is used to fix the second end 22 of the conductive connector 200 after being cut.

[0062] Specifically, the press mechanism 17 has a pressing force acting on the conductive connector 200, so that the conductive connector 200 is pressed onto the winding surface 12, so that the press mechanism 17 can cooperate with the first fixing mechanism 13 and the second fixing mechanism 14 to fix the conductive connector 200 at the same time. Among them, the position where the press mechanism 17 presses the conductive connector 200 is close to the first fixing mechanism 13, so that when the conductive connector 200 is cut off, the first fixing mechanism 13 and the second fixing mechanism 14 can fix the first end 21 of the conductive connector 200, and the press mechanism 17 can fix the second end 22 of the conductive connector 200, so that the first and tail ends of the conductive connector 200 are fixed respectively, thereby preventing the first end 21 and the second end 22 of the conductive connector 200 from detaching from the carrier 100 after the conductive connector 200 is cut off, so as to facilitate the subsequent processing of the conductive connector 200 and improve the processing efficiency of the battery string. Among them, when the carrier 100 has a receiving groove 11, the position where the press mechanism 17 presses the conductive connector 200 is close to the receiving groove 11.

[0063] More specifically, the press mechanism 17 includes a pressing member 171, which has a degree of freedom of movement, so that the pressing member 171 has a pressing position for pressing the conductive connector 200 and a separation position for separating from the conductive connector 200. When the pressing member 171 is in the pressing position, the pressing member 171 has a pressing force acting on the conductive connector 200. When the pressing member 171 is in the separation position, the pressing member 171 is separated from the conductive connector 200, so that the conductive connector 200 can continue to be processed in the next step.

[0064] The pressing member 171 may be driven by a cylinder.

[0065] like Figure 8 As shown, as an implementation, the present application further provides a processing device 300 for a conductive connector 200 , and the processing device 300 includes a carrier 100 and a processing component 31 .

[0066] The processing assembly 31 includes an operating mechanism 311 for transferring the fixing member 400. The operating mechanism 311 is movable so that the operating mechanism 311 has a placement position close to the carrier 100. When the operating mechanism 311 is in the placement position, the operating mechanism 311 can place the fixing member 400 on the conductive connecting member 200 so that the fixing member 400 can be connected with the conductive connecting member 200 to fix the conductive connecting member 200. When the carrier 100 has a receiving groove 11, the operating mechanism 311 can place the fixing member 400 on the conductive connecting member 200 at the opening of the receiving groove 11.

[0067] It can be understood that in the present application, the conductive connector 200 is a welding strip and the number of the conductive connectors 200 is not unique. Therefore, after the conductive connector 200 is cut off, the cut-off part of the conductive connector 200 is divided into the head and tail ends. Since the head and tail ends of the conductive connector 200 lose connection, the conductive connector 200 will be scattered. However, due to the setting of the fixing member 400, when the conductive connector 200 is cut off, the fixing member 400 can avoid the conductive connector 200 from being scattered, so that when the moving component 32 drives the conductive connector 200 to move, there will be no contact between the conductive connectors 200, thereby avoiding short circuits between battery cells due to contact between the conductive connectors 200; at the same time, the spacing between the conductive connectors 200 can be kept equidistant for laying.

[0068] It should be noted that the extending direction of the fixing member 400 is parallel to the rotation axis of the carrier 100 ; the fixing member 400 and the conductive connecting member 200 are connected by welding or bonding.

[0069] In this embodiment, two fixing members 400 are provided, and the two fixing members 400 are distributed on the conductive connecting member 200 along the rotation direction of the carrier 100. Exemplarily, one of the fixing members 400 is located in the first fixing space formed by the first fixing mechanism 13 and the second fixing mechanism 14, so that the first fixing mechanism 13 and the second fixing mechanism 14 can fix the conductive connecting member 200 by fixing the fixing member 400; the other fixing member 400 is located between the third fixing mechanism 15 and the fourth fixing mechanism 16 (refer to Figure 6 ) so that the third fixing mechanism 15 and the fourth fixing mechanism 16 can fix the conductive connecting member 200 by fixing the fixing member 400; or another fixing member 400 is fixed by the pressing mechanism 17 (refer to Figure 7 ) is pressed onto the winding surface 12. Through the above arrangement, the fixing member 400 can fix both ends of the conductive connector 200 at the same time, thereby preventing the both ends of the conductive connector 200 from falling off from the carrier 100 after being cut.

[0070] Exemplarily, the fixing member 400 can be set as a bus bar. After the fixing member 400 is laid following the conductive connector 200, the bus bar can be welded with the battery cell to form a battery string, which is beneficial to improve the processing efficiency of the battery string. As another embodiment, the fixing member 400 can be set as a metal bar, which can be connected to the operating mechanism 311 and welded to the conductive connector 200. It is only necessary to cut and separate the fixing member 400 from the conductive connector 200 after the fixing member 400 is laid following the conductive connector 200. In summary, the present application does not limit the structural form of the fixing member 400.

[0071] As an implementation method, the fixing method of the operating mechanism 311 to the fixing member 400 is one of bonding and adsorption connection. Specifically, the present application does not limit the bonding method between the operating mechanism 311 and the fixing member 400, and it is only required that the operating mechanism 311 and the fixing member 400 can be separated under the action of an external force after bonding; the operating mechanism 311 can be provided with an adsorption hole, and the fixing member 400 is adsorbed on the operating mechanism 311 by forming a negative pressure in the adsorption hole, thereby realizing the adsorption connection between the operating mechanism 311 and the fixing member 400.

[0072] As an implementation, the processing assembly 31 includes a heating mechanism 312 , which is disposed close to the operating mechanism 311 , and the conductive connecting member 200 and the fixing member 400 are welded by the heating mechanism 312 .

[0073] Specifically, the processing assembly 31 includes a supporting body 313, and the heating mechanism 312 and the operating mechanism 311 are both arranged on the supporting body 313, or the heating mechanism 312 is independent of the supporting body 313. It is only required that the heating mechanism 312 can heat the conductive connecting member 200 and the fixing member 400. The present application does not limit the position of the heating mechanism 312.

[0074] As another implementation, the fixing member 400 is sticky so that the fixing member 400 and the conductive connector 200 are bonded. It should be noted that the present application does not limit the bonding method between the fixing member 400 and the conductive connector 200, and it is only required that the fixing member 400 and the conductive connector 200 can be separated under the action of an external force after bonding.

[0075] It should be noted that the connection stability between the operating mechanism 311 and the fixing member 400 is lower than the connection stability between the fixing member 400 and the conductive connector 200. Therefore, after the fixing member 400 and the conductive connector 200 are connected, even if the operating mechanism 311 moves to a position away from the carrier 100, the fixing member 400 will not move with the operating mechanism 311, thereby making the fixing member 400 attached to the conductive connector 200, which is beneficial to the subsequent processing of the conductive connector 200 and improving the processing efficiency of the battery string.

[0076] As an implementation, the processing assembly 31 includes a cutting mechanism 314, and the cutting mechanism 314 has a degree of freedom of movement, so that the cutting mechanism 314 has a cutting position close to the carrier 100. When the cutting mechanism 314 is in the cutting position and the first fixing mechanism 13 and the second fixing mechanism 14 fix the conductive connector 200, the cutting mechanism 314 can cut the conductive connector 200, so that the cutting mechanism 314 can separate the head and tail ends of the conductive connector 200. When the carrier 100 has a receiving groove 11, the cutting mechanism 314 can cut the conductive connector 200 located at the opening of the receiving groove 11.

[0077] The cutting mechanism 314 is capable of cutting the conductive connecting member 200 located between the two fixing members 400 .

[0078] It should be noted that the freedom of movement of the operating mechanism 311 and the cutting mechanism 314 can be achieved by the movement of the supporting body 313, or the freedom of movement of the operating mechanism 311 and the cutting mechanism 314 can be achieved by the operating mechanism 311 and the cutting mechanism 314 being able to move relative to the supporting body 313, which is not limited in this application.

[0079] like Fig. 9As shown, as an implementation, the processing device 300 also includes a moving component 32. The moving component 32 is movable so that the moving component 32 has a working position and a fixed position close to the carrier 100. When the moving component 32 is in the fixed position, the moving component 32 can be fixed to the second fixing mechanism 14 so that the moving component 32 is fixed to the conductive connector 200; when the conductive connector 200 is cut off, the moving component 32 can move from the fixed position to the working position so that the moving component 32 drives the conductive connector 200 to move to a connection position that can be bonded to the battery cell. In this way, by moving the moving component 32 between the fixed position and the working position, the moving component 32 can drive one end of the cut conductive connector 200 to move from the carrier 100 to the connection position, thereby realizing the unfolding and laying of the conductive connector 200, which is beneficial to the bonding of the conductive connector 200 and the battery cell, so as to improve the welding efficiency of the battery cell. In the process where the moving component 32 drives one end of the cut conductive connecting member 200 to move from the carrier 100 to the connecting position, the carrier 100 rotates synchronously, so that the conductive connecting member 200 is output from the carrier 100 .

[0080] In this embodiment, the battery cells can be arranged at equal intervals first, and then the conductive connector 200 can be laid on the battery cells to achieve the connection between the conductive connector 200 and the battery cells; or the conductive connector 200 can be laid first, and then the battery cells can be arranged at equal intervals on the conductive connector 200.

[0081] Specifically, the fixing method of the moving component 32 and the second fixing mechanism 14 is one of bonding, magnetic connection and adsorption connection. Among them, the present application does not limit the bonding method between the moving component 32 and the second fixing mechanism 14, and it is only necessary that the moving component 32 and the second fixing mechanism 14 can be separated under the action of external force after bonding; or a magnet or metal part is provided in the moving component 32, and the second fixing mechanism 14 is provided as a metal part or magnet that cooperates with the magnet, so that the moving component 32 and the second fixing mechanism 14 can be fixed by the magnetic attraction between the magnets or the attraction between the magnet and the metal part; or an adsorption hole is provided on the moving component 32, and a negative pressure is formed in the adsorption hole so that the second fixing mechanism 14 can be adsorbed by the moving component 32.

[0082] It should be noted that the magnet in the moving component 32 and / or the second fixing mechanism 14 can be configured as an electromagnet.

[0083] It should be noted that the bonding stability between the moving component 32 and the second fixing mechanism 14 is greater than the connection stability between the first fixing mechanism 13 and the receiving groove 11; or the magnetic connection stability between the moving component 32 and the second fixing mechanism 14 is greater than the connection stability between the first fixing mechanism 13 and the receiving groove 11; or the adsorption force between the moving component 32 and the second fixing mechanism 14 is greater than the connection stability between the first fixing mechanism 13 and the receiving groove 11, so that the moving component 32 can move the first fixing mechanism 13 out of the receiving groove 11, and then the first fixing mechanism 13 and the second fixing mechanism 14 always keep the conductive connecting member 200 fixed, and the moving component 32 can realize the synchronous movement of the conductive connecting member 200 and the first fixing mechanism 13 by driving the movement of the second fixing mechanism 14.

[0084] Optionally, the moving component 32 has a lifting freedom perpendicular to the rotation axis direction of the carrier 100 , so that the moving component 32 can move to a fixed position by its own movement, thereby enabling the moving component 32 to fix the second fixing mechanism 14 .

[0085] like Fig. 9 , Fig.10 and Fig.11 As shown, optionally, the processing device 300 includes a pushing component 33, and the pushing component 33 is located on one side or both sides of the carrier 100 along the rotation axis direction of the carrier 100. The length of the first fixing mechanism 13 along the rotation axis direction of the carrier 100 is greater than the length of the carrier 100 along the rotation axis direction of the carrier 100, so that the part of the first fixing mechanism 13 that exceeds the carrier 100 is formed with a pushing portion 131, and the pushing component 33 can have a pushing force acting on the pushing portion 131, and the pushing force can separate the first fixing mechanism 13 from the carrier 100, so that the first fixing mechanism 13 can be moved to the moving component 32 in a fixed position. At this time, the moving component 32 may not have a degree of freedom of lifting and lowering, that is, the first fixing mechanism 13 and the second fixing mechanism 14 connected to the first fixing mechanism 13 and the conductive connector 200 can be moved to the moving component 32 by the pushing component 33, so that the moving component 32 can fix the second fixing mechanism 14. Wherein, when the carrier 100 has a receiving groove 11, the pushing force can separate the first fixing mechanism 13 from the receiving groove 11.

[0086] In this embodiment, the pushing assembly 33 includes a pushing cylinder 331 and a pushing member 332 . The pushing cylinder 331 is used to drive the pushing member 332 to move, so that the pushing member 332 can push the first fixing mechanism 13 .

[0087] like Fig.12 As shown, the present application also provides a method for processing a conductive connecting member 200, the processing method comprising:

[0088] S1: Winding the conductive connecting member 200 on the carrier 100 having rotational freedom, and pre-fixing the conductive connecting member 200;

[0089] S2: moving the moving component 32 to a fixed position, and fixing the moving component 32 to the conductive connecting member 200;

[0090] S3: Cut off the conductive connecting member 200;

[0104] like Fig.15 As shown, more specifically, between step S11 and step S12, the following is also included:

[0105] S111: rotating the carrier 100 so that the receiving slot 11 of the carrier 100 is close to the operating mechanism 311;

[0106] S112 : placing the two fixing members 400 on the conductive connecting member 200 located at the opening of the receiving groove 11 through the operating mechanism 311 , and connecting the two fixing members 400 to the conductive connecting member 200 .

[0108] It should be noted that although the steps shown in the above process or the flowchart of the accompanying drawings are shown in a logical order in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here. For example, the order of step S12 and step S13 may be swapped, as shown in FIG. Fig.16 As shown, step S1 includes:

[0109] S11: Winding the conductive connecting member 200 onto the carrier 100 having rotational freedom;
