[0041] The singular forms "a", "an", and "the" used in the specification and the appended claims are intended to include plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein means and includes any or all possible combinations of one or more associated listed items.

[0042] As shown in FIGS. 1 and 2, the present application provides a carrier 100 for winding a conductive connecting piece 200. In the present application, the conductive connecting piece 200 is a solder strip, through which independent battery pieces can be welded, so that the independent battery pieces form a battery string after welding. It can be understood that the conductive connecting piece 200 can be a circular solder strip, a triangular solder strip, etc., and the present application does not limit the structure of the conductive connecting piece 200.

[0043] It should be noted that the number of conductive connecting pieces 200 can be adjusted according to actual needs, and the winding of the conductive connecting pieces 200 on the carrier 100 is equidistant winding, so that the laying of the conductive connecting pieces 200 is also equidistant laying.

[0044] Specifically, the carrier 100 has a rotation freedom degree, and the carrier 100 has a winding surface 12 for winding the conductive connecting piece 200, and the winding surface 12 is arranged around the rotation axis of the carrier 100. Wherein, the winding direction of the conductive connecting piece 200 is consistent with the rotation direction of the carrier 100, or the winding direction of the conductive connecting piece 200 is opposite to the rotation direction of the carrier 100, which is not limited by the present application.

[0045] More specifically, for better embodying the embodiments of the present application, the present application takes the carrier 100 in the form of a cylinder as an example for illustration. It should be noted that the carrier 100 can also be in the form of a prism, a cylinder, or the like, and the present application does not make any limitation, as long as the carrier 100 can have a rotational degree of freedom.

[0046] As an implementation manner, the carrier 100 comprises a first fixing mechanism 13 and a second fixing mechanism 14. The first fixing mechanism 13 is located on the carrier 100 and detachably fixed with the carrier 100. The second fixing mechanism 14 is connected with the first fixing mechanism 13 in cooperation to form a first fixing space for fixing the conductive connecting piece 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 connecting piece 200 along the radial direction of the carrier 100, so that the conductive connecting piece 200 is located between the first fixing mechanism 13 and the second fixing mechanism 14, thereby facilitating the fixing of the conductive connecting piece 200 by the first fixing mechanism 13 and the second fixing mechanism 14. 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 200. In addition, the detachable fixing of the first fixing mechanism 13 with the carrier 100 can make the first fixing mechanism 13 fixed with or separated from the carrier 100, thereby facilitating the subsequent processing of the conductive connecting piece 200, and further improving the processing efficiency of the battery string.

[0047] As an alternative implementation manner, the carrier 100 comprises 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 rotational direction of the carrier 100. The third fixing mechanism 15 can be detachably fixed with the carrier 100. 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 connecting piece 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 rotational direction of the carrier 100, so that the first fixing mechanism 13 and the second fixing mechanism 14 can cooperate to fix the conductive connecting piece 200, and the third fixing mechanism 15 and the fourth fixing mechanism 16 can cooperate to fix the conductive connecting piece 200. In addition, the detachable fixing of the third fixing mechanism 15 with the carrier 100 can make the third fixing mechanism 15 fixed with or separated from the carrier 100, thereby facilitating the subsequent processing of the conductive connecting piece 200, and further improving the processing efficiency of the battery string.

[0048] As shown in FIG. 3 and FIG. 4, the carrier 100 has a receiving groove 11, which has at least one opening on the winding surface 12. At this time, the first fixing mechanism 13 is located in the receiving groove 11 and detachably fixed with the receiving groove 11, and the second fixing mechanism 14 is located outside the receiving groove 11, and the first fixing mechanism 13 and the second fixing mechanism 14 form a first fixing space for fixing the conductive connecting piece 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 connecting piece 200 along the radial direction of the carrier 100, so that the conductive connecting piece 200 is located between the first fixing mechanism 13 and the second fixing mechanism 14, thereby facilitating the fixing of the conductive connecting piece 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 connecting piece 200. In addition, the detachable fixing of the first fixing mechanism 13 and the receiving groove 11 can make the first fixing mechanism 13 fixed or separated from the receiving groove 11, thereby facilitating the subsequent processing of the conductive connecting piece 200, and further improving the processing efficiency of the battery string.

[0049] As an alternative implementation, when the carrier 100 has the receiving groove 11, the first fixing mechanism 13 and the third fixing mechanism 15 are distributed in the receiving groove 11 along the rotation direction of the carrier 100, the third fixing mechanism 15 can be detachably fixed with the receiving groove 11, and the fourth fixing mechanism 16 is located outside the receiving groove 11, and the third fixing mechanism 15 and the fourth fixing mechanism 16 form a second fixing space for fixing the conductive connecting piece 200. Specifically, the second fixing mechanism 14 and the fourth fixing mechanism 16 are both located outside the receiving groove 11, and the second fixing mechanism 14 and the fourth fixing mechanism 16 are distributed outside the receiving groove 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 connecting piece 200, and the third fixing mechanism 15 and the fourth fixing mechanism 16 can cooperate to fix the conductive connecting piece 200. In addition, the detachable fixing of the third fixing mechanism 15 and the receiving groove 11 can make the third fixing mechanism 15 fixed or separated from the receiving groove 11, thereby facilitating the subsequent processing of the conductive connecting piece 200, and further improving the processing efficiency of the battery string.

[0050] In the present embodiment, the first fixing mechanism 13 is bonded with the receiving groove 11. It should be noted that the present application does not limit the bonding mode between the first fixing mechanism 13 and the receiving groove 11, as long as the first fixing mechanism 13 and the receiving groove 11 can be separated under the action of external force after being bonded.

[0051] Or the first fixing mechanism 13 is connected with the accommodating groove 11 through magnetism. For example, the first fixing mechanism 13 can be provided as a magnet, and a magnet can be arranged in the accommodating groove 11, so that the first fixing mechanism 13 and the accommodating groove 11 are connected through the attraction of the two magnet parts. For example, the first fixing mechanism 13 can be provided as a metal part, and a magnet can be arranged in the accommodating groove 11, so that the first fixing mechanism 13 and the accommodating groove 11 are connected through the characteristic that the magnet can attract the metal part. For example, the first fixing mechanism 13 can be provided as a magnet, and a metal part can be arranged in the accommodating groove 11, so that the first fixing mechanism 13 and the accommodating groove 11 are connected through the characteristic 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 accommodating groove 11 can be kept or disconnected through the energization or de-energization of the electromagnet, thereby facilitating the connection convenience or separation convenience between the first fixing mechanism 13 and the accommodating groove 11.

[0052] Or the first fixing mechanism 13 is adsorbed in the accommodating groove 11. Specifically, the accommodating groove 11 can be provided with an adsorption hole, and the first fixing mechanism 13 can be adsorbed in the accommodating groove 11 by forming a negative pressure in the adsorption hole. Through the above arrangement, the adsorption connection between the first fixing mechanism 13 and the accommodating groove 11 can be formed, thereby facilitating the connection convenience or separation convenience between the first fixing mechanism 13 and the accommodating groove 11.

[0053] In the present embodiment, the third fixing mechanism 15 is connected with the accommodating groove 11 through magnetism, or the third fixing mechanism 15 is adsorbed in the accommodating groove 11. Wherein, the connection between the third fixing mechanism 15 and the accommodating groove 11 is the same as the connection between the first fixing mechanism 13 and the accommodating groove 11, the magnetism connection between the third fixing mechanism 15 and the accommodating groove 11 is the same as the magnetism connection between the first fixing mechanism 13 and the accommodating groove 11, and the adsorption connection between the third fixing mechanism 15 and the accommodating groove 11 is the same as the adsorption connection between the first fixing mechanism 13 and the accommodating groove 11, so the present application will not be described again.

[0054] As shown in FIG. 5 and FIG. 6, when the conductive connecting piece 200 is cut off, the conductive connecting piece 200 will form the first end 21 and the second end 22, that is, the conductive connecting piece 200 will form the first end and the second end. Through the above setting, the first fixing mechanism 13 and the second fixing mechanism 14 can fix the first end 21 of the conductive connecting piece 200, and the third fixing mechanism 15 and the fourth fixing mechanism 16 can fix the second end 22 of the conductive connecting piece 200, so that the first end and the second end of the conductive connecting piece 200 are fixed respectively, thereby avoiding the first end 21 and the second end 22 of the conductive connecting piece 200 after being cut off from the carrier 100, so as to facilitate the subsequent processing of the conductive connecting piece 200, and improve the processing efficiency of the battery string.

[0055] In the embodiment, the second fixing mechanism 14 is bonded with the first fixing mechanism 13, or the second fixing mechanism 14 is magnetically connected with the first fixing mechanism 13. The bonding of the second fixing mechanism 14 with the first fixing mechanism 13 is the same as the bonding of the first fixing mechanism 13 with the accommodating groove 11, and the magnetic connection of the second fixing mechanism 14 with the first fixing mechanism 13 is the same as the magnetic connection of the first fixing mechanism 13 with the accommodating groove 11, which will not be described herein. It should be noted that when the second fixing mechanism 14 is bonded with the first fixing mechanism 13, the adhesion between the second fixing mechanism 14 and the first fixing mechanism 13 is greater than the adhesion between the first fixing mechanism 13 and the accommodating groove 11, or the adhesion 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 accommodating groove 11; when the second fixing mechanism 14 is magnetically connected with the first fixing mechanism 13, the magnetic attraction between the second fixing mechanism 14 and the first fixing mechanism 13 is greater than the adhesion between the first fixing mechanism 13 and the accommodating 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 accommodating groove 11, so that after the second fixing mechanism 14 cooperates with the first fixing mechanism 13, one end of the conductive connecting piece 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 driven to move together under external force, so as to drive the conductive connecting piece 200 to move.

[0056] In the present embodiment, the fourth fixing mechanism 16 is bonded with the third fixing mechanism 15, or the fourth fixing mechanism 16 is magnetically connected with the third fixing mechanism 15. The bonding between the fourth fixing mechanism 16 and the third fixing mechanism 15 is the same as the bonding between the second fixing mechanism 14 and the first fixing mechanism 13, and the magnetic connection between the fourth fixing mechanism 16 and the third fixing mechanism 15 is the same as the magnetic connection between the second fixing mechanism 14 and the first fixing mechanism 13, which will not be described herein. Through the above arrangement, the fourth fixing mechanism 16 and the third fixing mechanism 15 are used in cooperation with the second fixing mechanism 14 and the first fixing mechanism 13. When the second fixing mechanism 14 and the first fixing mechanism 13 are used to fix and transfer the first end 21 of the conductive connecting piece 200, the carrier 100 rotates. At this time, the fourth fixing mechanism 16 and the third fixing mechanism 15 are only used to fix the second end 22 of the conductive connecting piece 200. Before the conductive connecting piece 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 pulling of external force.

[0057] It should be noted that when the carrier 100 does not have the accommodating groove 11, the first fixing mechanism 13 is bonded with the carrier 100, or the first fixing mechanism 13 is magnetically connected with the carrier 100, or the first fixing mechanism 13 is adsorbed on the carrier 100; the third fixing mechanism 15 is bonded with the carrier 100, or the third fixing mechanism 15 is magnetically connected with the carrier 100, or the third fixing mechanism 15 is adsorbed on the carrier 100.

[0058] 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.

[0059] As another alternative implementation, as shown in FIG. 7, the carrier 100 is provided with a pressing mechanism 17 for cooperating with the first fixing mechanism 13 and the second fixing mechanism 14 to fix the conductive connecting piece 200, that is, in the present embodiment, the third fixing mechanism 15 and the fourth fixing mechanism 16 are not arranged. Among them, the first fixing mechanism 13 and the second fixing mechanism 14 are used to fix the first end 21 of the cut conductive connecting piece 200, and the pressing mechanism 17 is used to fix the second end 22 of the cut conductive connecting piece 200.

[0060] Specifically, the pressing mechanism 17 has a pressing force acting on the conductive connecting piece 200 to press the conductive connecting piece 200 to the winding surface 12, so that the pressing mechanism 17 can cooperate with the first fixing mechanism 13 and the second fixing mechanism 14 to fix the conductive connecting piece 200. Wherein, the position of the pressing mechanism 17 pressing the conductive connecting piece 200 is close to the first fixing mechanism 13, so that when the conductive connecting piece 200 is cut off, the first fixing mechanism 13 and the second fixing mechanism 14 can fix the first end 21 of the conductive connecting piece 200, and the pressing mechanism 17 can fix the second end 22 of the conductive connecting piece 200, so that the first end 21 and the second end 22 of the conductive connecting piece 200 are fixed respectively, thereby avoiding the first end 21 and the second end 22 of the conductive connecting piece 200 after being cut off from the carrier 100, so as to facilitate the subsequent processing of the conductive connecting piece 200, and improve the processing efficiency of the battery string. Wherein, when the carrier 100 has the accommodating groove 11, the position of the pressing mechanism 17 pressing the conductive connecting piece 200 is close to the accommodating groove 11.

[0061] More specifically, the pressing mechanism 17 includes a pressing piece 171, and the pressing piece 171 has a freedom of movement, so that the pressing piece 171 has a pressing position for pressing the conductive connecting piece 200 and a separation position for separating from the conductive connecting piece 200. When the pressing piece 171 is in the pressing position, the pressing piece 171 has a pressing force acting on the conductive connecting piece 200. When the pressing piece 171 is in the separation position, the pressing piece 171 separates from the conductive connecting piece 200, so that the conductive connecting piece 200 can continue the next step of processing.

[0062] Wherein, the pressing piece 171 can be driven by a pneumatic cylinder.

[0063] As an implementation manner, the application further provides a processing device 300 of the conductive connecting piece 200, as shown in FIG. 8, the processing device 300 includes the carrier 100 and a processing assembly 31.

[0064] Wherein, the processing assembly 31 includes an operating mechanism 311 for transferring the fixing piece 400, and the operating mechanism 311 is movable to have a placement position close to the carrier 100, and when the operating mechanism 311 is in the placement position, the operating mechanism 311 can place the fixing piece 400 on the conductive connecting piece 200, so that the fixing piece 400 can be connected with the conductive connecting piece 200 to fix the conductive connecting piece 200. Wherein, when the carrier 100 has the accommodating groove 11, the operating mechanism 311 can place the fixing piece 400 on the conductive connecting piece 200 at the opening of the accommodating groove 11.

[0065] It can be understood that in the present application, the conductive connecting piece 200 is a solder strip and the number of the conductive connecting piece 200 is not unique. Therefore, after the conductive connecting piece 200 is cut off, the cut end of the conductive connecting piece 200 is divided into two ends, and because the two ends of the conductive connecting piece 200 lose connection, the conductive connecting piece 200 will appear to be scattered. But because of the arrangement of the fixing piece 400, when the conductive connecting piece 200 is cut off, the fixing piece 400 can avoid the conductive connecting piece 200 from being scattered, so that when the moving assembly 32 drives the conductive connecting piece 200 to move, the conductive connecting piece 200 will not be in contact with each other, thereby avoiding short circuit between the battery pieces due to the contact between the conductive connecting pieces 200; at the same time, it can also make the spacing between the conductive connecting pieces 200 remain equidistant to lay.

[0066] It should be noted that the extension direction of the fixing piece 400 is parallel to the rotation axis of the carrier 100; the connection mode of the fixing piece 400 and the conductive connecting piece 200 is welding or bonding.

[0067] In the present embodiment, two fixing pieces 400 are provided, and the two fixing pieces 400 are distributed on the conductive connecting piece 200 along the rotation direction of the carrier 100. For example, one of the fixing pieces 400 is located in the first fixed 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 piece 200 by fixing the fixing piece 400; the other fixing piece 400 is located in the second fixed space formed by the third fixing mechanism 15 and the fourth fixing mechanism 16 (refer to FIG. 6), so that the third fixing mechanism 15 and the fourth fixing mechanism 16 can fix the conductive connecting piece 200 by fixing the fixing piece 400; or the other fixing piece 400 is pressed onto the winding surface 12 by the pressing mechanism 17 (refer to FIG. 7). Through the above arrangement, the two ends of the conductive connecting piece 200 can be fixed at the same time by the fixing of the fixing piece 400, thereby avoiding the two ends of the conductive connecting piece 200 from falling off the carrier 100 after being cut off.

[0068] For example, the fixing piece 400 can be arranged as a bus bar, which can be welded with the battery piece to form a battery string after the fixing piece 400 is laid with the conductive connecting piece 200, which is conducive to improving the processing efficiency of the battery string. As another embodiment, the fixing piece 400 can be arranged as a metal strip, which can be connected with the operating mechanism 311 and welded with the conductive connecting piece 200, and only needs to be cut and separated from the conductive connecting piece 200 after the fixing piece 400 is laid with the conductive connecting piece 200. In summary, the structure of the fixing piece 400 is not limited in the present application.

[0069] As an implementation form, the fixing manner of the fixing mechanism 311 to the fixing member 400 is one of bonding and adsorption connection. Specifically, the application does not limit the bonding manner between the fixing mechanism 311 and the fixing member 400, and only needs to enable the fixing mechanism 311 and the fixing member 400 to be separated under the action of an external force after bonding. The fixing mechanism 311 can be provided with an adsorption hole, and the fixing member 400 is adsorbed on the fixing mechanism 311 by forming a negative pressure in the adsorption hole, so as to realize the adsorption connection of the fixing mechanism 311 and the fixing member 400.

[0070] As an implementation form, the processing assembly 31 comprises a heating mechanism 312, and the heating mechanism 312 is arranged close to the fixing mechanism 311. The heating mechanism 312 is used to weld the conductive connecting member 200 and the fixing member 400.

[0071] Specifically, the processing assembly 31 comprises a support body 313, and the heating mechanism 312 and the fixing mechanism 311 are arranged on the support body 313, or the heating mechanism 312 is independent of the support body 313, and only needs to enable the heating mechanism 312 to heat the conductive connecting member 200 and the fixing member 400. The application does not limit the position of the heating mechanism 312.

[0072] As another implementation form, the fixing member 400 has adhesion, so as to bond the fixing member 400 and the conductive connecting member 200. It should be noted that the application does not limit the bonding manner between the fixing member 400 and the conductive connecting member 200, and only needs to enable the fixing member 400 and the conductive connecting member 200 to be separated under the action of an external force after bonding.

[0073] It should be noted that the connection stability of the fixing mechanism 311 and the fixing member 400 is less than the connection stability of the fixing member 400 and the conductive connecting member 200, so that after the fixing member 400 and the conductive connecting member 200 are connected, even if the fixing mechanism 311 moves to a position away from the carrier 100, the fixing member 400 will not move with the fixing mechanism 311, thereby enabling the fixing member 400 to be attached to the conductive connecting member 200, so as to facilitate the subsequent processing of the conductive connecting member 200 and improve the processing efficiency of the battery string.

[0074] As an implementation form, the processing assembly 31 comprises a cutting mechanism 314, and the cutting mechanism 314 has a movement degree of freedom, so as to enable the cutting mechanism 314 to have 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 connecting member 200, the cutting mechanism 314 can cut the conductive connecting member 200, so that the cutting mechanism 314 can divide the first end and the second end of the conductive connecting member 200. When the carrier 100 has the accommodating groove 11, the cutting mechanism 314 can cut the conductive connecting member 200 located at the opening of the accommodating groove 11.

[0075] The cutting mechanism 314 is capable of cutting the conductive connecting member 200 located between the two fixing members 400.

[0076] It should be noted that the movement freedom of the operating mechanism 311 and the cutting mechanism 314 can be realized by the movement of the support body 313, or the operating mechanism 311 and the cutting mechanism 314 can move relative to the support body 313, which is not limited in the present application.

[0077] As shown in FIG. 9, as an implementation manner, the processing device 300 further comprises a moving assembly 32. The moving assembly 32 is movable so that the moving assembly 32 has a working position and a fixed position close to the carrier 100. When the moving assembly 32 is in the fixed position, the moving assembly 32 is capable of being fixed with the second fixing mechanism 14 so that the moving assembly 32 is fixed with the conductive connecting member 200. In the case that the conductive connecting member 200 is cut off, the moving assembly 32 is capable of moving from the fixed position to the working position so that the moving assembly 32 drives the conductive connecting member 200 to move to a connecting position capable of being attached with the battery piece. In this way, by moving the moving assembly 32 between the fixed position and the working position, the moving assembly 32 is capable of driving one end of the cut-off conductive connecting member 200 to move from the carrier 100 to the connecting position, thereby realizing the expansion and laying of the conductive connecting member 200, and then facilitating the attachment of the conductive connecting member 200 and the battery piece, so as to improve the welding efficiency of the battery piece. In the process that the moving assembly 32 drives one end of the cut-off conductive connecting member 200 to move from the carrier 100 to the connecting position, the carrier 100 is synchronously rotated, thereby outputting the conductive connecting member 200 from the carrier 100.

[0078] In the present embodiment, the battery pieces can be arranged at equal intervals first, and then the conductive connecting member 200 is laid on the battery pieces, thereby realizing the connection of the conductive connecting member 200 and the battery pieces; or the conductive connecting member 200 can be laid first, and then the battery pieces are arranged at equal intervals on the conductive connecting member 200.

[0079] Specifically, the mobile assembly 32 is fixed to the second fixing mechanism 14 in one of the following manners: adhesion, magnetic connection, and adsorption. The adhesion between the mobile assembly 32 and the second fixing mechanism 14 is not limited in the present application, and only needs to be able to separate the mobile assembly 32 and the second fixing mechanism 14 under the action of an external force. Alternatively, the mobile assembly 32 is provided with a magnet or a metal piece, and the second fixing mechanism 14 is provided with a metal piece or a magnet matched with the magnet, so that the mobile assembly 32 and the second fixing mechanism 14 can be fixed by the magnetic attraction between the magnet and the magnet or the adsorption between the magnet and the metal piece. Alternatively, the mobile assembly 32 is provided with an adsorption hole, and the second fixing mechanism 14 can be adsorbed by the mobile assembly 32 by forming a negative pressure in the adsorption hole.

[0080] It should be noted that the magnet in the mobile assembly 32 and / or the second fixing mechanism 14 can be an electromagnet.

[0081] It should be noted that the adhesion stability between the mobile assembly 32 and the second fixing mechanism 14 is greater than the connection stability between the first fixing mechanism 13 and the accommodating groove 11, or the magnetic connection stability between the mobile assembly 32 and the second fixing mechanism 14 is greater than the connection stability between the first fixing mechanism 13 and the accommodating groove 11, or the adsorption force between the mobile assembly 32 and the second fixing mechanism 14 is greater than the connection stability between the first fixing mechanism 13 and the accommodating groove 11, so that the mobile assembly 32 can move the first fixing mechanism 13 out of the accommodating groove 11, and the first fixing mechanism 13 and the second fixing mechanism 14 can always fix the conductive connecting piece 200, and the mobile assembly 32 can move the second fixing mechanism 14 to realize the synchronous movement of the conductive connecting piece 200 and the first fixing mechanism 13.

[0082] Optionally, the mobile assembly 32 has a lifting degree of freedom perpendicular to the rotation axis direction of the carrier 100, so that the mobile assembly 32 can move to a fixed position by itself, so that the mobile assembly 32 can fix the second fixing mechanism 14.

[0083] As shown in FIG. 9, FIG. 10 and FIG. 11, optionally, the processing device 300 comprises a pushing assembly 33 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 beyond the carrier 100 is formed with a pushing part 131, the pushing assembly 33 can have a pushing force acting on the pushing part 131, 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 assembly 32 in the fixed position. At this time, the moving assembly 32 can not have the lifting degree of freedom, that is, the first fixing mechanism 13 and the second fixing mechanism 14 connected with the first fixing mechanism 13 and the conductive connecting piece 200 can be moved to the moving assembly 32 by the pushing assembly 33, so that the moving assembly 32 can fix the second fixing mechanism 14. When the carrier 100 has the accommodating groove 11, the pushing force can separate the first fixing mechanism 13 from the accommodating groove 11.

[0084] In the embodiment, the pushing assembly 33 comprises a pushing cylinder 331 and a pushing piece 332, the pushing cylinder 331 is used to drive the movement of the pushing piece 332, so that the pushing piece 332 can push the first fixing mechanism 13.

[0085] As shown in FIG. 12, the application also provides a processing method of the conductive connecting piece 200, the processing method comprises:
