[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0038] As Figure 1 、 Figure 2 and Figure 3 shown, the present application provides a battery string processing device 100, and the processing device 100 includes a first carrier 11 and a fixing component 12. The first carrier 11 is used for winding a conductive connection member, and the first carrier 11 has a rotational degree of freedom. Wherein, the fixing component 12 has a translational degree of freedom, and the fixing component 12 can fix or connect one end of the cut conductive connection member 200. With such an arrangement, after the conductive connection member 200 is cut, the movement of the fixing component 12 can drive the conductive connection member 200 wound on the first carrier 11 to move, so as to realize the laying of the conductive connection member 200. Therefore, it is not necessary to manually lay the conductive connection member 200, thereby improving the processing efficiency of the battery string. At the same time, since the first carrier 11 has a rotational degree of freedom, during the process of the fixing component 12 driving the conductive connection member 200 to move, the first carrier 11 rotates simultaneously, so that the first carrier 11 does not interfere with the movement of the conductive connection member 200, which is beneficial to the laying of the conductive connection member 200.

[0039] Specifically, after the conductive connecting member 200 is cut, the first carrier 11 rotates so that the first carrier 11 can output the conductive connecting member 200. At this time, the fixing component 12 synchronously drives the conductive connecting member 200 to move, so that the movements of the first carrier 11 and the fixing component 12 can be coordinated, so that the conductive connecting member 200 can be moved to a connecting position where it can be attached to the battery cell 300.

[0040] Among them, the connecting position refers to the position where the conductive connecting member 200 is located when the cut conductive connecting member 200 can be attached to the battery cell 300. It can be understood that when the conductive connecting member 200 is in the connecting position, the conductive connecting member 200 can be attached to the battery cell 300 and can be connected, so that the conductive connecting member 200 and the battery cell 300 can form a battery string.

[0041] To clearly illustrate the technical solution of the present application, the front, back, left, right, up, and down as shown in Figure 1 are also defined.

[0042] In the present application, the conductive connecting member 200 is a welding tape. Through the welding tape, the independent battery cells 300 can be welded, so that the independent battery cells 300 form a battery string after welding. It can be understood that the conductive connecting member 200 can be a circular welding tape, a triangular welding tape, etc. The present application does not limit the structural form of the conductive connecting member 200.

[0043] Specifically, the fixing component 12 has a working position and a fixing position close to the first carrier 11. When the fixing component 12 is in the fixing position, the fixing component 12 can fix the conductive connecting member 200. In the case where the conductive connecting member 200 is cut, the fixing component 12 can move from the fixing position to the working position, so that the fixing component 12 drives the conductive connecting member 200 to move to a connecting position where it can be attached to the battery cell 300. With such a setting, by moving the fixing component 12 between the fixing position and the working position, the fixing component 12 can drive the cut conductive connecting member 200 to move from the first carrier 11 to the connecting position, thereby realizing the unfolding and laying of the conductive connecting member 200, and then facilitating the attachment of the conductive connecting member 200 and the battery cell 300 to improve the welding efficiency of the battery cell 300.

[0044] In this embodiment, the battery cells 300 can be arranged at equal intervals first, and then the conductive connecting member 200 can be laid on the battery cells 300 to realize the connection between the conductive connecting member 200 and the battery cells 300; or the conductive connecting member 200 can be laid first, and then the battery cells 300 can be arranged at equal intervals on the conductive connecting member 200.

[0045] It should be noted that the number of the conductive connectors 200 can be adjusted according to actual requirements, and the winding of the conductive connectors 200 on the first carrier 11 is equidistant winding, so that the laying of the conductive connectors 200 is also equidistant laying.

[0046] Wherein, the fixed position refers to the position where the fixing component 12 is located when fixing the conductive connector 200 wound around the first carrier 11. The working position refers to the position where the fixing component 12 drives the cut conductive connector 200 to move to a position where it can be attached to the battery cell 300.

[0047] Optionally, the fixing component 12 includes a first clamping member 121 and a second clamping member 122. The second clamping member 122 has a degree of freedom of movement, so that the second clamping member 122 can approach or move away from the first clamping member 121. In the present application, the second clamping member 122 has a degree of freedom of movement in the left-right direction of the processing device 100. When the second clamping member 122 approaches the first clamping member 121, a clamping space for clamping one end of the conductive connector 200 is formed between the first clamping member 121 and the second clamping member 122. With such a setting, through the movement of the second clamping member 122, the second clamping member 122 can cooperate with the first clamping member 121 to clamp and release the conductive connector 200, which is beneficial for the fixing component 12 to drive the conductive connector 200 to move to the connection position when the fixing component 12 clamps the conductive connector 200, and is also beneficial for the conductive connector 200 to be unfolded and laid when the fixing component 12 releases the conductive connector 200.

[0048] Specifically, when the fixing component 12 is in the fixed position, the second clamping member 122 approaches the first clamping member 121, so that the second clamping member 122 and the first clamping member 121 cooperate to form a clamping space to clamp and fix one end of the conductive connector 200, which is beneficial for cutting the conductive connector 200. After the cutting is completed, the fixing component 12 drives the conductive connector 200 to move to the connection position. At this time, the second clamping member 122 moves away from the first clamping member 121, so that the fixing component 12 releases the conductive connector 200, enabling the conductive connector 200 wound around the first carrier 11 to be unfolded and laid, and thus the conductive connector 200 is automatically laid, which is beneficial for improving the processing efficiency of the battery string.

[0049] Understandably, in the present application, the conductive connection member 200 is a solder strip and the number of the conductive connection members 200 is not unique. Therefore, after the conductive connection member 200 is cut off, the cut-off part of the conductive connection member 200 is divided into a head end and a tail end. Since the head end and the tail end of the conductive connection member 200 are disconnected, the conductive connection member 200 will be in a scattered state. However, when the conductive connection member 200 is cut off, the clamping of the conductive connection member 200 by the fixing assembly 12 can prevent the conductive connection member 200 from being scattered, so that when the fixing assembly 12 drives the conductive connection member 200 for laying, the conductive connection members 200 will not come into contact with each other, thereby avoiding short circuits between the battery cells 300 due to the contact between the conductive connection members 200.

[0050] As an optional implementation manner, the first carrier 11 may be provided with a receiving groove 111. When the fixing assembly 12 is in a fixed position, at least part of the first clamping member 121 or at least part of the second clamping member 122 can enter the receiving groove 111, that is, at least part of the first clamping member 121 is located in the receiving groove 111, or at least part of the second clamping member 122 is located in the receiving groove 111, so that the first clamping member 121 and the second clamping member 122 can be on both sides of the conductive connection member 200, which is beneficial to the first clamping member 121 and the second clamping member 122 clamping the conductive connection member 200.

[0051] As Figure 2 shown, as an implementation manner, the fixing assembly 12 is provided with a first fixing portion 123 for fixing the first fixing member 500. The first fixing portion 123 is located on the first clamping member 121. When the second clamping member 122 approaches the first clamping member 121, a clamping space for clamping one end of the conductive connection member 200 is formed between the first fixing portion 123 and the second clamping member 122, or the first fixing portion 123 is located on the second clamping member 122. When the second clamping member 122 approaches the first clamping member 121, a clamping space for clamping one end of the conductive connection member 200 is formed between the first fixing portion 123 and the first clamping member 121. With such a setting, when the conductive connection member 200 is in the clamping space, through the setting of the first fixing member 500, the cut-off part of the conductive connection member 200 can be further clamped and limited, so as to prevent the conductive connection member 200 from being scattered at the cut-off part, and further keep the distance between the conductive connection members 200 equidistant for laying.

[0052] Taking the example where the first fixing part 123 is located on the first clamping part 121 for illustration. When the fixing component 12 moves to the fixing position, the second clamping part 122 approaches the first clamping part 121, so that the second clamping part 122 can cooperate with the first fixing part 123 to form a clamping space to clamp one end of the conductive connection part 200. When the first fixing part 123 cooperates with the second clamping part 122 to clamp the conductive connection part 200, since the first fixing member 500 is fixed to the first clamping part 121, the clamping of the conductive connection part 200 by the second clamping part 122 and the first fixing part 123 is the clamping of the conductive connection part 200 by the first fixing member 500 and the second clamping part 122. Thus, through the connection between the first fixing member 500 and the conductive connection part 200, the situation of scattering will not occur after the conductive connection part 200 is cut off, and further, the distance between the conductive connection parts 200 is kept equidistant, so that the conductive connection parts 200 can meet the processing requirements of the battery string. After the cutting is completed, the fixing component 12 drives the conductive connection part 200 to move to the connection position. Then, the second clamping part 122 moves away from the first clamping part 121. Also, since the first fixing member 500 is already connected to the conductive connection part 200, the fixing component 12 releases the first fixing member 500 while releasing the conductive connection part 200, and further, the conductive connection parts 200 on the first carrier 11 can be automatically laid at equal intervals. Among them, the connection method between the first fixing member 500 and the conductive connection part 200 will be described below and will not be elaborated here.

[0053] Exemplarily, the first fixing part 123 is provided with a first adsorption hole 1231. By forming a negative pressure in the first adsorption hole 1231, the first fixing member 500 is adsorbed on the first fixing part 123, so as to improve the connection stability between the first fixing member 500 and the first fixing part 123, and further, during the operation of the fixing component 12, the situation that the first fixing member 500 falls off from the first fixing part 123 is avoided.

[0054] Or the first fixing part 123 is used for bonding the first fixing member 500. Through the bonding between the first fixing part 123 and the first fixing member 500, the connection stability between the first fixing part 123 and the first fixing member 500 is improved, and further, during the operation of the fixing component 12, the situation that the first fixing member 500 falls off from the first fixing part 123 is avoided.

[0055] Or the first fixing part 123 is used for welding with the first fixing member 500. With such a setting, the situation that the first fixing member 500 falls off from the first fixing part 123 can be avoided, which is beneficial to improving the connection stability between the first fixing part 123 and the first fixing member 500.

[0056] Among them, when the first fixing portion 123 is provided with a first adsorption hole 1231, when the fixing assembly 12 drives the conductive connecting member 200 to move to the connection position and the fixing assembly 12 no longer clamps the conductive connecting member 200, no negative pressure is formed in the first adsorption hole 1231, so that the first fixing member 500 can automatically fall off from the first fixing portion 123, which is conducive to the separation of the first fixing member 500 from the first fixing portion 123, so that the first fixing member 500 can be laid together with the conductive connecting member 200.

[0057] Among them, when the first fixing portion 123 is used to bond the first fixing member 500, a foam rubber strip is provided on the first fixing portion 123. The foam rubber strip has adhesiveness, so that the first fixing portion 123 can be used to bond the first fixing member 500. It should be noted that the adhesiveness between the first fixing portion 123 and the first fixing member 500 can overcome the gravity of the first fixing member 500, so that the first fixing member 500 can be fixed on the first fixing portion 123, and the adhesiveness between the first fixing portion 123 and the first fixing member 500 cannot overcome the total gravity after the first fixing member 500 and the conductive connecting member 200 are connected. When the fixing assembly 12 drives the conductive connecting member 200 to move to the connection position and the fixing assembly 12 no longer clamps the conductive connecting member 200, the first fixing member 500 can automatically fall off from the first fixing portion 123, which is conducive to the separation of the first fixing member 500 from the first fixing portion 123, so that the first fixing member 500 can be laid together with the conductive connecting member 200.

[0058] Among them, when the first fixing portion 123 is used to weld with the first fixing member 500, when the fixing assembly 12 drives the conductive connecting member 200 to move to the connection position and the fixing assembly 12 no longer clamps the conductive connecting member 200, the first fixing member 500 can be cut off from the conductive connecting member 200, so that the conductive connecting member 200 can be laid.

[0059] Optionally, to achieve the connection between the first fixing member 500 and the conductive connecting member 200, the fixing assembly 12 of the present application is provided with a first heating portion (not shown in the figure) for heating the conductive connecting member 200 and the first fixing member 500, so that the conductive connecting member 200 and the first fixing member 500 are welded through the first heating portion. Alternatively, the first fixing member 500 of the present application has adhesiveness, so that the first fixing member 500 and the conductive connecting member 200 are adhered. It can be understood that by welding or adhering the conductive connecting member 200 to the first fixing member 500, the connection stability between the conductive connecting member 200 and the first fixing member 500 is improved, so that when the fixing assembly 12 releases the conductive connecting member 200, the first fixing member 500 can be separated from the first fixing portion 123 and adhered to the conductive connecting member 200. At the same time, by improving the connection stability between the conductive connecting member 200 and the first fixing member 500, it is beneficial for the first fixing member 500 to further limit the cut-off portion of the conductive connecting member 200, and further prevent the situation that the cut-off portion of the conductive connecting member 200 is scattered. Moreover, when the fixing assembly 12 drives the conductive connecting member 200 to move for laying, through the connection between the conductive connecting member 200 and the first fixing member 500, the first fixing member 500 can follow the conductive connecting member 200 for laying.

[0060] It should be noted that when the connection method between the first fixing portion 123 and the first fixing member 500 is adhesion, and the connection method between the first fixing member 500 and the conductive connecting member 200 is adhesion, the adhesion stability between the first fixing portion 123 and the first fixing member 500 is weaker than the adhesion stability between the first fixing member 500 and the conductive connecting member 200. Therefore, when the fixing assembly 12 lays the conductive connecting member 200, the first fixing member 500 can be separated from the first fixing portion 123 and follow the conductive connecting member 200 for laying, thereby avoiding the situation that the first fixing member 500 adheres to the first fixing portion 123 and cannot fall off.

[0061] In some embodiments, the first heating portion may be a heating wire disposed in the first fixing portion 123, so that the first fixing member 500 and the conductive connecting member 200 can be heated through the heating wire, so that the first fixing member 500 and the conductive connecting member 200 are welded. In some embodiments, the first heating portion may also be a heating lamp disposed on or outside the first fixing portion 123, so that the first fixing member 500 and the conductive connecting member 200 are heated through the heating lamp, so that the first fixing member 500 and the conductive connecting member 200 are welded. The present application does not limit the structural form and installation position of the first heating portion, as long as the first heating portion can heat and weld the first fixing member 500 and the conductive connecting member 200.

[0062] Specifically, taking the example of the first adsorption hole 1231 and the first heating part provided on the fixing component 12, the description is as follows. First, a negative pressure is formed through the first adsorption hole 1231 so that the first fixing member 500 can be adsorbed on the first fixing part 123. After the fixing component 12 is moved to the fixing position, the second clamping member 122 approaches the first clamping member 121, so that the first fixing member 500 can cooperate with the second clamping member 122 to clamp the conductive connection member 200. At this time, the first fixing member 500 and the conductive connection member 200 are heated through the first heating part, so that the first fixing member 500 and the conductive connection member 200 are welded and fixed. Then the conductive connection member 200 is cut off. After the cutting is completed, the fixing component 12 drives the conductive connection member 200 to move to the connection position, and then the second clamping member 122 moves away from the first clamping member 121 to enable the fixing component 12 to release the conductive connection member 200, thereby realizing the laying of the conductive connection member 200. At the same time, no negative pressure is formed in the first adsorption hole 1231, and the first fixing member 500 is welded to the conductive connection member 200, so that the first fixing member 500 can be detached from the first fixing part 123 and the first fixing member 500 can follow the conductive connection member 200 for laying.

[0063] As an implementation manner, the first fixing member 500 is set as the bus bar 400. After the first fixing member 500 follows the conductive connection member 200 for laying, the above-mentioned bus bar 400 can be welded to the battery cell 300 to form a battery string, which is beneficial to improving the processing efficiency of the battery string. As another implementation manner, the first fixing member 500 can be set as a metal bar, and the metal bar can also be bonded to the first fixing part 123 or welded to the conductive connection member 200. Only after the first fixing member 500 follows the conductive connection member 200 for laying, the first fixing member 500 can be cut and separated from the conductive connection member 200. In summary, the present application does not limit the structural form of the first fixing member 500.

[0064] As Figure 1 and Figure 3 As shown in the figure, as an implementation manner, the fixing component 12 has a moving degree of freedom in the front-rear direction of the processing device 100 and a moving degree of freedom in the left-right direction of the processing device 100. The fixing component 12 moves in the front-rear direction of the processing device 100 to the clamping position, and the fixing component 12 moves in the left-right direction of the processing device 100 to the working position. Among them, the first clamping member 121 and the first carrier 11 at least partially overlap in the front-rear direction of the processing device 100, thereby improving the structural compactness of the processing device 100. To avoid interference between the fixing component 12 and the first carrier 11 when the fixing component 12 moves in the front-rear direction of the processing device 100, the first carrier 11 is provided with a receiving groove 111. When the fixing component 12 is in the fixing position, the first clamping member 121 is at least partially located in the receiving groove 111.

[0065] With the above settings, when the fixing component 12 moves in the front - rear direction of the processing device 100, the accommodating groove 111 can prevent the first carrier 11 from interfering with the movement of the fixing component 12. Thus, it is beneficial for the first clamping member 121 and the second clamping member 122 of the fixing component 12 to move to the left and right sides of the conductive connection member 200 at the accommodating groove 111, and further beneficial for the first clamping member 121 and the second clamping member 122 to clamp the conductive connection member 200.

[0066] As another implementation manner, the fixing component 12 has adhesiveness, and the fixing component 12 can bond with one end of the cut conductive connection member 200, so that the fixing component 12 can directly bond with the conductive connection member 200. With such a setting, through the bonding method, the fixing component 12 is directly connected to the conductive connection member 200, and then the fixing component 12 can drive the conductive connection member 200 to move for laying through bonding. With such a setting, there is no need to clamp the conductive connection member 200, which is beneficial to simplifying the structure of the conductive connection member 200. At the same time, the bonding method can limit the cut conductive connection member 200 by the fixing component 12, and further prevent the conductive connection member 200 from being scattered at the cut - off position.

[0067] Specifically, in some embodiments, a rubber strip is provided on the fixing component 12, and the rubber strip can bond with the conductive connection member 200, so as to improve the connection stability between the conductive connection member 200 and the fixing component 12, and then the fixing component 12 can drive the conductive connection member 200 to move to the connection position for laying through the rubber strip. When the fixing component 12 moves to the working position, only the rubber strip needs to be cut off.

[0068] As another implementation manner, the fixing component 12 is provided with a heating part for heating the conductive connection member 200, and through the heating part, one end of the cut conductive connection member 200 can be welded to the fixing component 12. With such a setting, through the welding method of the heating part, the conductive connection member 200 is connected to the fixing component 12, and then the fixing component 12 can drive the conductive connection member 200 to move for laying through welding. With such a setting, there is no need to clamp the conductive connection member 200, which is beneficial to simplifying the structure of the conductive connection member 200. At the same time, the welding method can limit the cut conductive connection member 200 by the fixing component 12, so as to prevent the conductive connection member 200 from being scattered at the cut - off position.

[0069] Specifically, in some embodiments, a heating wire is provided inside the fixing component 12, so that the conductive connecting member 200 can be heated through the heating wire, enabling the conductive connecting member 200 to be welded to the fixing component 12. In some embodiments, a heating lamp is provided on or outside the fixing component 12, so that the conductive connecting member 200 can be heated through the heating lamp, enabling the conductive connecting member 200 to be welded to the fixing component 12. Therefore, the present application does not limit the structural form and installation position of the heating part on the fixing component 12. When the fixing component 12 drives the conductive connecting member 200 to move to the connection position, it is only necessary to cut and separate the conductive connecting member 200 from the fixing component 12, thereby realizing the laying of the conductive connecting member 200.

[0070] As another implementation manner, the fixing component 12 has adsorption property, and the fixing component 12 can adsorb one end of the cut conductive connecting member 200. Optionally, adsorption holes are provided on the fixing component 12, and a negative pressure is formed in the adsorption holes to adsorb one end of the cut conductive connecting member 200 on the fixing component 12. Through the above settings, a negative pressure is formed in the adsorption holes, so that the conductive connecting member 200 is directly connected to the fixing component 12, enabling the fixing component 12 to drive the conductive connecting member 200 to move for laying. At the same time, the adsorption method can limit the cut conductive connecting member 200 by the fixing component 12, thereby avoiding the situation that the conductive connecting member 200 is scattered at the cut. And when the fixing component 12 drives the conductive connecting member 200 to move to the working position, it is only necessary to make no negative pressure formed in the adsorption holes, so that the conductive connecting member 200 can be directly detached from the fixing component 12, which is beneficial to the separation of the conductive connecting member 200 from the fixing component 12. With such settings, it is not necessary to cut the conductive connecting member 200 connected to the fixing component 12, which is beneficial to the fixing component 12 to drive the conductive connecting member 200 for laying.

[0071] As Figure 3 shown, as an implementation manner, the first carrier 11 of the present application may be provided with a receiving groove 111, or the first carrier 11 may not be provided with a receiving groove 111, which can be specifically adjusted according to actual needs.

[0072] It should be noted that the present application takes the first carrier 11 having a rotational degree of freedom and having a receiving groove 111 as an example for description. The first carrier 11 has a winding surface 113 for winding the conductive connecting member 200, and the winding surface 113 is arranged around the rotation axis of the first carrier 11. Among them, the receiving groove 111 has at least one opening located on the winding surface 113, so that the fixing component 12 can pass through the opening on the winding surface 113 and at least partially enter the receiving groove 111.

[0073] Specifically, when the first carrier 11 has a receiving groove 111, the fixing component 12 can be set as a fixture component, and the fixture component has a moving degree of freedom, so that the fixture component has a working position and a clamping position close to the first carrier 11;

[0074] When the fixture component is in the clamping position, the receiving groove 111 can allow at least part of the fixture component to enter, so that the fixture component can clamp the conductive connecting member 200. In the case where the conductive connecting member 200 is cut off, the fixture component can move from the clamping position to the working position, so that the fixture component drives the conductive connecting member 200 to move to a connecting position where it can be attached to the battery cell 300. Through the above arrangement, after the conductive connecting member 200 is cut off, the fixture component can drive the conductive connecting member 200 wound on the first carrier 11 to move, thereby realizing the automatic laying of the conductive connecting member 200, and further improving the processing efficiency of the battery string. At the same time, since the first carrier 11 has a rotational degree of freedom, during the process of the fixture component driving the conductive connecting member 200 to move, the first carrier 11 will not interfere with the movement of the conductive connecting member 200, which is conducive to the laying of the conductive connecting member 200.

[0075] It should be noted that the working position of the fixture component is the working position of the fixing component 12, and the clamping position of the fixture component is the fixing position of the fixing component 12. Therefore, the structure and working process of the fixture component will not be elaborated in this application.

[0076] In this embodiment, the fixture component includes a first clamping member 121 and a second clamping member 122. Among them, the structures of the first clamping member 121 and the second clamping member 122 have been described above and will not be elaborated here. More specifically, when the fixture component is in the clamping position, at least part of the first clamping member 121 is located in the receiving groove 111, or at least part of the second clamping member 122 is located in the receiving groove 111. Further, at least part of the first clamping member 121 passes through the opening on the winding surface 113 and is located in the receiving groove 111, or at least part of the second clamping member 122 passes through the opening on the winding surface 113 and is located in the receiving groove 111.

[0077] It should be noted that the first carrier 11 and the fixture component constitute a processing device for the conductive connecting member 200, that is, the processing device for the conductive connecting member 200 includes the first carrier 11 and the fixture component.

[0078] In the present application, a plurality of placement areas 112 are provided on the first carrier 11. The plurality of placement areas 112 are spaced apart and disposed on the winding surface 113. The placement areas 112 extend substantially along the rotation axis direction of the first carrier 11. Each placement area 112 fixes a bus bar 400, and there is an interval for accommodating a battery cell 300 between two adjacent placement areas 112. With such a setting, a battery string can be formed through the welding of the conductive connection member 200, the bus bar 400 and the battery cell 300. Therefore, arranging the bus bar 400 on the first carrier 11 enables the bus bar 400 to be connected to the conductive connection member 200 wound on the first carrier 11, so that the bus bar 400 can follow the conductive connection member 200 for laying, which is conducive to improving the processing efficiency of the battery string. At the same time, there is an interval for accommodating a battery cell 300 between two placement areas 112, which enables a battery cell 300 to be directly placed between two adjacent bus bars 400 on the laid conductive connection member 200. Thus, it is not necessary to adjust the position of the bus bar 400 on the laid conductive connection member 200 for welding the battery cell 300, the bus bar 400 and the conductive connection member 200, which is conducive to improving the processing efficiency of the battery string. Moreover, when the fixing assembly 12 drives the conductive connection member 200 to move, the first carrier 11 can follow the conductive connection member 200 to rotate around the rotation axis, thereby avoiding interference of the first carrier 11 with the rotation of the conductive connection member 200, which is conducive to improving the smoothness of laying the conductive connection member 200.

[0079] Optionally, a second adsorption hole 1121 is provided on each placement area 112, and a negative pressure is formed in the second adsorption hole 1121 to adsorb the corresponding bus bar 400 on the placement area 112. With such a setting, the negative pressure formed in the second adsorption hole 1121 can adsorb the bus bar 400, thereby improving the connection stability between the bus bar 400 and the placement area 112, and further preventing the bus bar 400 from falling off the placement area 112. At the same time, when the conductive connection member 200 follows the fixing assembly 12 for laying, no negative pressure is formed in the second adsorption hole 1121, so that the bus bar 400 can follow the conductive connection member 200 for laying without interfering with the movement of the bus bar 400 following the conductive connection member 200.

[0080] As another implementation manner, each placement area 112 has adhesiveness, and the placement area 112 is adhered to the bus bar 400. With such a setting, the connection between the bus bar 400 and the placement area 112 can be realized by adhesion, which is conducive to simplifying the structure of the first carrier 11.

[0081] To connect the bus bar 400 on the placement area 112 to the conductive connection member 200, the first carrier 11 of the present application further includes a carrier body 114 and a second heating portion (not shown in the figure). The second heating portion is used to heat the bus bar 400 and the conductive connection member 200, and the second heating portion is located inside the carrier body 114 or is disposed adjacent to the carrier body 114, so that the conductive connection member 200 and the bus bar 400 are welded through the second heating portion. With such a setting, through the welding of the conductive connection member 200 and the bus bar 400, the connection stability between the bus bar 400 on the first carrier 11 and the conductive connection member 200 is improved, so that when the conductive connection member 200 moves for laying, the bus bar 400 on the first carrier 11 can be separated from the placement area 112 and adhered to the conductive connection member 200, avoiding the situation where the conductive connection member 200 adheres in the placement area 112 and does not move with the conductive connection member 200.

[0082] In some embodiments, the second heating portion may be a heating wire disposed in the placement area 112, so as to heat the conductive connection member 200 and the bus bar 400 through the heating wire, so that the conductive connection member 200 can be welded to the bus bar 400. In some embodiments, the second heating portion may be a heating tube disposed inside or outside the carrier body 114, so as to heat the conductive connection member 200 and the bus bar 400 through the heating tube, so that the conductive connection member 200 can be welded to the bus bar 400. Therefore, the present application does not limit the structural form and the setting position of the second heating portion, as long as it can heat and weld the conductive connection member 200 and the bus bar 400 on the first carrier 11.

[0083] To connect the bus bar 400 on 112 to the conductive connection member 200, as another implementation manner, the bus bar 400 and the conductive connection member 200 are adhesively bonded. The connection between the bus bar 400 and the conductive connection member 200 can be realized through adhesive bonding, so that when the conductive connection member 200 moves for laying, the bus bar 400 on the first carrier 11 can be separated from the placement area 112 and adhered to the conductive connection member 200, thereby simplifying the structure of the first carrier 11.

[0084] In some embodiments, a rubber strip is disposed on the side of the bus bar 400 on the first carrier 11 facing away from the first carrier 11, so that the bus bar 400 on the first carrier 11 can be adhesively bonded to the conductive connection member 200.

[0085] It should be noted that when the connection between the placement area 112 and the bus bar 400 on the first carrier 11 is by bonding, and the connection between the bus bar 400 on the first carrier 11 and the conductive connecting member 200 is by bonding, the bonding stability between the bus bar 400 on the first carrier 11 and the conductive connecting member 200 is stronger than the bonding stability between the placement area 112 and the bus bar 400 on the first carrier 11. Thus, when the fixing assembly 12 drives the conductive connecting member 200 to move, the conductive connecting member 200 can drive the bus bar 400 on the first carrier 11 to disengage from the placement area 112, so that the conductive connecting member 200 can drive the bus bar 400 to be laid, thereby avoiding the situation where the conductive connecting member 200 cannot drive the bus bar 400 on the first carrier 11 to move for laying. With such a setting, it is beneficial to improve the welding efficiency of the bus bar 400 and the battery cell 300, and thus improve the processing efficiency of the battery string.

[0086] Specifically, taking the example that the second adsorption hole 1121 is provided in the placement area 112 and the second heating part is provided on the first carrier 11, first, a negative pressure is formed through the second adsorption hole 1121 so that the second fixing member 600 can be adsorbed on the placement area 112. Then, the conductive connecting member 200 is wound around the first carrier 11. Then, the second fixing member 600 and the conductive connecting member 200 are heated and welded through the second heating part. When the fixing assembly 12 drives the conductive connecting member 200 to move for laying, no negative pressure is formed in the second adsorption hole 1121, so that the conductive connecting member 200 can disengage from the first carrier 11. At the same time, the conductive connecting member 200 can drive the bus bar 400 on the first carrier 11 to move together for laying through welding, thereby improving the processing efficiency of the battery string.

[0087] It can be understood that the bus bar 400 on the first carrier 11 can also be arranged on the side of the conductive connecting member 200 facing away from the first carrier 11, that is, first wind the conductive connecting member 200 around the first carrier 11, and then adsorb the bus bar 400 on the first carrier 11, so that the bus bar 400 can cooperate with the placement area 112 to clamp the conductive connecting member 200. Then, the bus bar 400 and the conductive connecting member 200 are heated and welded through the second heating part, so that the bus bar can follow the movement of the conductive connecting member 200 for laying, thereby improving the processing efficiency of the battery string.

[0088] It should be noted that when the bus bar 400 on the first carrier 11 is arranged on the side of the conductive connecting member 200 away from the first carrier 11, the bus bar 400 is only adsorbed in the placement area 112 by the negative pressure formed in the second adsorption hole 1121. At the same time, in the present application, since there is a distance between the conductive connecting members 200, the negative pressure formed in the second adsorption hole 1121 can adsorb the bus bar 400 through the distance between the conductive connecting members 200, so that the bus bar 400 can be fixed to the placement area 112.

[0089] It should be noted that when the conductive connecting member 200 is first wound around the first carrier 11, a guiding groove (not shown in the figure) is provided on the first carrier 11, and the conductive connecting member 200 can be limited by the guiding groove, so that when the conductive connecting member 200 is wound around the first carrier 11, it is beneficial to fix the position of the conductive connecting member 200 on the first carrier 11.

[0090] As Figure 1 、 Figure 4 and Figure 5 shown, as an implementation manner, the battery string processing device 100 further includes a pressing tool assembly 13, and the pressing tool assembly 13 has a pressing force acting on the conductive connecting member 200 to press the conductive connecting member 200 onto the first carrier 11. In the present application, the pressing tool assembly 13 is arranged at the upper end of the fixing assembly 12. At the same time, the cutting position of the conductive connecting member 200 is between the fixing assembly 12 and the pressing tool assembly 13, so that the conductive connecting member 200 forms two ends, a head end and a tail end. Through the above setting, the pressing tool assembly 13 and the fixing assembly 12 can respectively fix the upper and lower ends of the conductive connecting member 200 at the cutting position, preventing the conductive connecting member 200 from loosening during the cutting process, and thus being beneficial to cutting the conductive connecting member 200 so that the conductive connecting member 200 forms two ends, a head end and a tail end. Among them, the pressing tool assembly 13 and the fixing assembly 12 can respectively fix the head end and the tail end of the conductive connecting member 200.

[0091] In the present application, the conductive connecting member 200 is a solder strip and the number of solder strips is not unique. Therefore, after the solder strip is cut, the cut part of the conductive connecting member 200 is divided into two ends, a head end and a tail end. Since the head end and the tail end of the conductive connecting member 200 are no longer connected, the conductive connecting member 200 will be in a scattered state. However, when the conductive connecting member 200 is cut, the pressing of the conductive connecting member 200 by the pressing tool assembly 13 can prevent the conductive connecting member 200 from being scattered, so that when the fixing assembly 12 drives the conductive connecting member 200 to be laid, the conductive connecting members 200 will not come into contact with each other, thereby preventing short circuits between the battery cells 300 due to the contact between the conductive connecting members 200.

[0092] Further, the pressing tool assembly 13 includes a pressing member 131 which has a degree of freedom of movement such that the pressing member 131 has a pressing position for pressing the conductive connection member 200 and a separating position separated from the conductive connection member 200. When the pressing member 131 is in the pressing position, the pressing member 131 has a pressing force acting on the conductive connection member 200. In the present application, the pressing member 131 and the fixing assembly 12 are at least partially located on the left side of the first carrier 11. Therefore, in the present application, the pressing member 131 has a degree of freedom of movement in the left-right direction of the processing device 100. With such a setting, by moving the pressing member 131 between the pressing position and the separating position, the pressing and separating of the conductive connection member 200 by the pressing tool assembly 13 are achieved.

[0093] Specifically, when it is necessary to cut the conductive connection member 200, the pressing member 131 moves to the pressing position so that the pressing member 131 can press the conductive connection member 200, and then the fixing assembly 12 fixes the conductive connection member 200, so that the upper and lower ends of the cutting position of the conductive connection member 200 are fixed, which is conducive to cutting the conductive connection member 200. After the cutting is completed, the fixing assembly 12 drives the conductive connection member 200 to move in for laying, and at the same time, the first carrier 11 rotates in cooperation with the movement of the conductive connection member 200. At this time, the pressing tool assembly 13 rotates with the first carrier 11 so that the pressing tool assembly 13 can maintain the pressing of the conductive connection member 200 until the conductive connection member 200 moves to the connection position, and the pressing member 131 moves to the separating position, so that the pressing member no longer limits the conductive connection member 200. Furthermore, during the movement of the conductive connection member 200, by pressing the conductive connection member 200 by the pressing member 131, the conductive connection member 200 is prevented from slipping off the first carrier 11, which is conducive to the conductive connection member 200 following the fixing assembly 12 to move for laying.

[0094] Optionally, the press tool assembly 13 is provided with a second fixing portion 132 for fixing the second fixing member 600. The second fixing portion 132 is located on the side of the pressing member 131 facing the first carrier 11. By providing the second fixing member 600, the pressing effect of the press tool assembly 13 on the conductive connection member 200 can be improved, which is beneficial to cutting the conductive connection member 200. In some embodiments, the second fixing portion 132 is provided on the side of the pressing member 131 facing the first carrier 11. At the same time, the second fixing member 600 is provided on the side of the second fixing portion 132 facing the first carrier 11. When the pressing member 131 drives the second fixing portion 132 to move to the pressing position, the second fixing member 600 on the second fixing portion 132 abuts against the conductive connection member 200, and the second fixing member 600 is connected to the conductive connection member 200, so that the second fixing member 600 can press and fix the conductive connection member 200, thereby avoiding the scattered situation at the cutting portion of the conductive connection member 200. It should be noted that the connection method between the second fixing member 600 and the conductive connection member 200 will be specifically described below and will not be elaborated here.

[0095] Exemplarily, the second fixing portion 132 is provided with a third adsorption hole 133. By forming a negative pressure in the third adsorption hole 133, the second fixing member 600 is adsorbed on the second fixing portion 132, thereby improving the connection stability between the second fixing member 600 and the second fixing portion 132. Furthermore, during the movement of the second fixing portion 132, the situation where the second fixing member 600 falls off the second fixing portion 132 is avoided.

[0096] Or the second fixing portion 132 is used for bonding with the second fixing member 600. By bonding the second fixing portion 132 and the second fixing member 600, the connection stability between the second fixing portion 132 and the second fixing member 600 is improved. Furthermore, during the movement of the second fixing portion 132, the situation where the second fixing member 600 falls off the second fixing portion 132 is avoided.

[0097] Wherein, when the second fixing portion 132 is provided with the third adsorption hole 133, when the fixing assembly 12 drives the conductive connection member 200 to move to the connection position and the fixing assembly 12 no longer clamps the conductive connection member 200, by no longer forming a negative pressure in the third adsorption hole 133, the second fixing member 600 can be separated from the second fixing portion 132, so that the second fixing member 600 can follow the conductive connection member 200 for laying.

[0098] Among them, when the second fixing part 132 is used for bonding the second fixing member 600, a foam rubber strip is provided on the second fixing part 132. The foam rubber strip has adhesiveness, so that the second fixing part 132 can be used to bond the second fixing member 600. It should be noted that the adhesiveness between the second fixing part 132 and the second fixing member 600 can overcome the gravity of the second fixing member 600, so that the second fixing member 600 can be fixed on the second fixing part 132, and the adhesiveness between the second fixing part 132 and the second fixing member 600 cannot overcome the total gravity after the second fixing member 600 is connected to the conductive connecting member 200. When the fixing assembly 12 drives the conductive connecting member 200 to move to the connection position and the fixing assembly 12 no longer clamps the conductive connecting member 200, the second fixing member 600 can automatically fall off from the second fixing part 132, which is beneficial to the separation of the second fixing member 600 from the second fixing part 132, so that the second fixing member 600 can be laid together with the conductive connecting member 200.

[0099] Optionally, to realize the connection between the second fixing member 600 and the conductive connecting member 200, the pressing tool assembly 13 of the present application includes a third heating part 135 for heating the conductive connecting member 200 and the second fixing member 600, so that the conductive connecting member 200 and the second fixing member 600 are welded through the third heating part 135. Alternatively, the second fixing member 600 of the present application has adhesiveness, so that the second fixing member 600 and the conductive connecting member 200 are bonded. It can be understood that by welding or bonding the conductive connecting member 200 and the second fixing member 600, the connection stability between the conductive connecting member 200 and the second fixing member 600 is improved. When the pressing member 131 moves from the pressing position to the separating position, the second fixing member 600 can be separated from the second fixing part 132 and attached to the conductive connecting member 200. At the same time, by improving the connection stability between the conductive connecting member 200 and the second fixing member 600, it is beneficial for the second fixing member 600 to further limit the cut-off part of the conductive connecting member 200, thereby preventing the situation that the cut-off part of the conductive connecting member 200 is scattered.

[0100] It should be noted that when the connection method between the second fixing part 132 and the second fixing member 600 is bonding, and the connection method between the second fixing member 600 and the conductive connecting member 200 is bonding, the bonding stability between the second fixing part 132 and the second fixing member 600 is weaker than the bonding stability between the second fixing member 600 and the conductive connecting member 200. When the fixing assembly 12 lays the conductive connecting member 200, the second fixing member 600 can be separated from the second fixing part 132 and laid together with the conductive connecting member 200.

[0101] Specifically, the third heating part 135 is located inside the pressing member 131 or near the pressing member 131, or the third heating part 135 is located on the fixing assembly.

[0102] In some embodiments, the third heating part 135 may be a heating wire disposed within the second fixing part 132, so that the second fixing member 600 and the conductive connecting member 200 can be heated by the heating wire, enabling welding of the second fixing member 600 and the conductive connecting member 200. In some embodiments, the third heating part 135 may also be a heating lamp disposed on or outside the fixing assembly 12, so that the second fixing member 600 and the conductive connecting member 200 are heated by the heating lamp, enabling welding of the second fixing member 600 and the conductive connecting member 200. In some embodiments, the third heating part 135 includes a cylinder 1351 and a heating tube 1352. The cylinder 1351 is fixedly installed on the fixing assembly 12. The cylinder 1351 is in transmission connection with the heating tube 1352, and the cylinder 1351 drives the heating tube 1352 to move towards the pressing member 131, so that the heating tube 1352 can heat the second fixing member 600 and the conductive connecting member 200, enabling welding of the second fixing member 600 and the conductive connecting member 200. Therefore, the present application does not limit the structural form and installation position of the third heating part 135, as long as the third heating part 135 can heat and weld the second fixing member 600 and the conductive connecting member 200.

[0103] Specifically, taking the example where the third adsorption hole 133 is provided on the second fixing part 132 and the third heating part 135 is provided on the pressing tool assembly 13 for illustration. First, a negative pressure is formed through the third adsorption hole 133, enabling the second fixing member 600 to be adsorbed onto the third fixing part. Then, the pressing member 131 approaches the first carrier 11, so that the second fixing member 600 can press the conductive connecting member 200 on the first carrier 11. Subsequently, the second fixing member 600 and the conductive connecting member 200 are heated and welded by the third heating part 135. Thus, when the pressing member 131 moves from the pressing position to the separating position, the second fixing member 600 can adhere to the conductive connecting member 200, and further enable the second fixing member 600 to move and be laid following the conductive connecting member 200.

[0104] As an implementation manner, the second fixing member 600 is set as a bus bar 400. Thus, after the second fixing member 600 is laid following the conductive connecting member 200, the above-mentioned bus bar 400 can be welded to the battery cells 300 through the conductive connecting member 200 to form a battery string, which is conducive to improving the processing efficiency of the battery string. As another implementation manner, the second fixing member 600 can be set as a metal bar, and the metal bar can also be connected to the second fixing part 132 and the conductive connecting member 200. It only needs to cut and separate the second fixing member 600 from the conductive connecting member 200 after the second fixing member 600 is laid following the conductive connecting member 200. The present application does not limit the structural form of the first fixing member 500.

[0105] Optionally, the pressing component 13 further includes a driving member 134. The driving member 134 is in transmission connection with the pressing member 131, and the driving member 134 is fixed to the first carrier 11. With such a setting, the driving member 134 can drive the pressing member 131 to move in the left-right direction of the processing device 100, so that the pressing member 131 can move between the pressing position and the separating position.

[0106] As Figure 1 and Figure 6 shown, as an implementation manner, the processing device 100 includes a second carrier 14. The second carrier 14 has a placement surface 141 for placing the battery cells 300 and / or the conductive connection members 200. Through the setting of the second carrier 14, the fixing component 12 can lay the conductive connection members 200 on the placement surface 141, and the welding of the battery string can be carried out on the placement surface 141, thereby improving the processing efficiency of the battery string.

[0107] It should be noted that before the conductive connection members 200 are laid on the placement surface 141, the battery cells 300 can be laid on the placement surface 141 first. Or after the conductive connection members 200 are laid on the placement surface 141, the battery cells 300 can be laid on the conductive connection members 200 for welding. Therefore, this application does not limit the laying sequence of the battery cells 300 and the conductive connection members 200 on the placement surface 141.

[0108] Specifically, the processing device 100 further includes a guide wheel 15 for guiding the cut conductive connection members 200. Along the up-down direction of the processing device 100, the placement surface 141 is the upper surface of the second carrier 14, and the uppermost end of the guide wheel 15 and the placement surface 141 are on the same horizontal plane. With such a setting, when the fixing component 12 drives the conductive connection members 200 to move for laying, the guide wheel 15 can guide the laying height of the conductive connection members 200. At the same time, since the uppermost end of the guide wheel 15 and the placement surface 141 are on the same horizontal plane, the conductive connection members 200 can be laid on the placement surface 141 more smoothly.

[0109] More specifically, the fixing component 12 is arranged close to the second carrier 14, and at least part of the fixing component 12 is located above the second carrier 14, so that the fixing component 12 can drive the conductive connection members 200 to move and lay them above the second carrier 14, and then the placement surface 141 on the second carrier 14 can carry the conductive connection members 200.

[0110] Optionally, the fixing component 12 has the freedom of movement along the vertical direction of the processing equipment 100, and / or the second carrier 14 has the freedom of movement along the vertical direction of the processing equipment 100. It can be understood that when the fixing component 12 drives the conductive connector 200 to move for laying, the fixing component 12 and / or the second carrier 14 move along the vertical direction of the processing equipment 100, so that the conductive connector 200 can be attached to the placement surface 141 on the second carrier 14, and then the conductive connector 200 can be laid on the placement surface 141. Such a configuration is conducive to the fixing component 12 laying the conductive connector 200 on the placement surface 141.

[0111] In some embodiments, the second carrier 14 can be a lifting platform, and the upper surface of the lifting platform is the placement surface 141. By raising and lowering the lifting platform, the distance between the conductive connector 200 and the placement surface 141 can be adjusted, so that the conductive connector 200 can be laid in contact with the placement surface 141.

[0112] In some embodiments, the fixing assembly 12 may include a lifting cylinder having the freedom to move in the up and down directions of the processing equipment 100. At the same time, the lifting cylinder is transmission-connected to the first clamping member 121 and the second clamping member 122, so that the lifting cylinder can drive the first clamping member 121 and the second clamping member 122 to move in the up and down directions of the processing equipment 100, thereby driving the conductive connecting member 200 clamped by the first clamping member 121 and the second clamping member 122 to move in the up and down directions, so that the conductive connecting member 200 can be laid in contact with the placement surface 141.

[0113] As an optional implementation, the processing equipment 100 of the present application includes a first carrier 11, a clamp assembly and a second carrier 14, that is, the processing equipment 100 of the present application includes a processing device for the conductive connector 200 composed of the first carrier 11 and the clamp assembly and the second carrier 14. When the clamp assembly is in the clamping position, the receiving groove 111 can allow at least part of the clamp assembly to enter, so that the clamp assembly can clamp the conductive connector 200; when the conductive connector 200 is cut off, the clamp assembly can move from the clamping position to the working position, so that the clamp assembly drives the conductive connector 200 to move to the placement surface 141 that can fit the battery cell 300.

[0114] As an embodiment, the present application discloses a carrier having rotational freedom and having a receiving groove. In addition, the carrier has a winding surface for winding the conductive connector 200, and the winding surface is arranged around the rotation axis of the carrier. The receiving groove has at least one opening located on the winding surface. It should be noted that the above-mentioned receiving groove is the receiving groove 111 of the first carrier 11, and the above-mentioned winding surface is the winding surface 113 of the first carrier 11, that is, the first carrier 11 in the above-mentioned embodiment is this carrier.

[0115] As Figure 7 shown, as an implementation, the present application also discloses a processing method for a battery string, and the processing method includes the following steps:

[0116] S1: Wind the conductive connecting member 200 around the first carrier 11 having a rotational degree of freedom;

[0117] S2: Move the fixture assembly to the clamping position, and the fixture assembly 41 clamps the conductive connecting member 200;

[0118] S3: Cut the conductive connecting member 200, and the cutting position of the conductive connecting member 200 is close to the fixture assembly;

[0119] S4: The fixture assembly moves from the clamping position to the working position to drive the conductive connecting member 200 to move from the first carrier 11 to the connecting position where it can be attached to the battery cell 300.

[0120] Wherein, the connecting position in step S4 refers to the second carrier 14, and the second carrier 14 is used to place the conductive connecting member 200 and / or the battery cell 300 so that the conductive connecting member 200 can be attached to the battery cell 300 on the second carrier 14.

[0121] As Figure 8 and Figure 9 shown, step S1 includes:

[0122] S11: Dispose the bus bars 400 at equal intervals along the rotation direction of the first carrier 11 on the first carrier 11;

[0123] Specifically, the bus bars 400 can be laid along with the conductive connecting member 200, and the bus bars 400 can be welded to the battery cell 300 and the conductive connecting member 200 to form a battery string. At the same time, the interval between adjacent bus bars 400 can accommodate one battery cell 300. Thus, in step S4, after the fixture assembly drives the conductive connecting member 200 to move and lay, there is no need to adjust the distance between the bus bars 400 on the conductive connecting member 200, which is conducive to improving the processing efficiency of the battery string.

[0124] S12: Wind the conductive connecting member 200 around the first carrier 11 so that the conductive connecting member 200 is wound around the bus bars 400.

[0125] Specifically, by winding the conductive connection member 200 around the first carrier 11, the first carrier 11 has a rotational degree of freedom. Thus, in step S4, when the conductive connection member 200 moves for laying, the first carrier 11 will rotate following the movement of the conductive connection member 200, so that the first carrier 11 will not interfere with the movement of the conductive connection member 200. Meanwhile, a second heating portion may be provided on the first carrier 11, and by means of the second heating portion, the conductive connection member 200 and the bus bar 400 are welded. Thus, in step S4, when the fixture assembly drives the conductive connection member 200 to move for laying, the bus bar 400 on the first carrier 11 can adhere to the conductive connection member 200 and lay together with the conductive connection member 200. More specifically, the bus bars 400 are arranged at equal intervals along the rotation direction of the first carrier 11 on the first carrier 11; the conductive connection member 200 is wound around the first carrier 11 provided with the bus bars 400, so that the conductive connection member 200 contacts and is welded to the bus bars 400.

[0126] Or step S1 includes:

[0127] S11: Wind the conductive connection member 200 around the first carrier 11;

[0128] Specifically, a guiding groove may be provided on the first carrier 11 to limit the guiding connection member 200 wound around the first carrier 11, thereby avoiding the situation that the guiding connection member 200 is offset on the first carrier 11.

[0129] S12: Fix the bus bar 400 on the first carrier 11 so that the bus bars 400 are arranged at equal intervals along the rotation direction of the first carrier 11 on the conductive connection member 200.

[0130] Specifically, first wind the conductive connection member 200 around the first carrier 11, then lay the bus bar 400 on the conductive connection member 200 and weld it through the second heating portion, which can make the bus bar 400 not directly contact the first carrier 11. Thus, in step S4 when the conductive connection member 200 is laid, the conductive connection member 200 can directly drive the bus bar 400 to move, and there will be no situation that the bus bar 400 is fixed on the first carrier 11, resulting in the bus bar 4 not laying together with the conductive connection member 200.

[0131] The fixture assembly includes a first clamping member 121 and a second clamping member 122.

[0132] As Figure 10 shown, step S2 includes:

[0133] S21: Move the fixture assembly to the clamping position;

[0134] Specifically, when the fixture assembly moves to the clamping position, it can move to the conductive connection member 200, which is beneficial for the fixture assembly to clamp the conductive connection member 200.

[0135] S22: The second clamping member 122 moves closer to the first clamping member 121 so that a clamping space for clamping one end of the conductive connection member 200 is formed between the first clamping member 121 and the second clamping member 122.

[0136] Specifically, by moving the second clamping member 122 closer to the first clamping member 121 to form a clamping space, the conductive connection member 200 wound around the first carrier 11 is clamped, realizing the fixation of the conductive connection member 200, which is beneficial for cutting the conductive connection member in step S3. At the same time, the fixture assembly can clamp the cut conductive connection member 200, which is beneficial for driving the cut conductive connection member 200 to move to the connection position in step S4.

[0137] Optionally, the fixture assembly includes a first fixing portion 123 for fixing the first fixing member 500. A clamping space for clamping one end of the conductive connection member 200 is formed between the first fixing portion 123 and the first clamping member 121, or a clamping space for clamping one end of the conductive connection member 200 is formed between the first fixing portion 123 and the second clamping member 122.

[0138] Therefore, step S2 further includes:

[0139] S23: When the fixture assembly clamps the conductive connection member 200, the first fixing member 500 is bonded or welded to the conductive connection member 200.

[0140] Specifically, the conductive connection member 200 is a welding tape and the number of conductive connection members 200 is not unique. Therefore, after the conductive connection member 200 is cut in step S3, the conductive connection members 200 will be scattered. Through the connection between the first fixing member 500 and the conductive connection member 200, the conductive connection member 200 can be limited, so that when the conductive connection member moves and is laid in step S4, the conductive connection members 200 will not come into contact with each other, thereby avoiding short circuits between the battery cells 300 due to the contact between the conductive connection members 200.

[0141] As Figure 11 shown, cutting the conductive connection member 200 in step S3 includes:

[0142] S31: The pressing tool assembly 13 presses the conductive connection member 200 onto the first carrier 11;

[0143] Specifically, the conductive connecting member 200 is tightly pressed by the pressing tool assembly 13, and at the same time, in cooperation with the clamping of the conductive connecting member 200 by the fixture assembly in step S2, the conductive connecting member 200 can be fixed, which is beneficial to cutting the conductive connecting member 200.

[0144] S32: Cut the conductive connecting member 200 located between the pressing tool assembly 13 and the fixture assembly.

[0145] Specifically, by cutting the conductive connecting member 200 on the first carrier 11, in step S4, the fixture assembly can drive the cut conductive connecting member 200 to move for laying.

[0146] More specifically, in step S4, the fixture assembly drives the cut conductive connecting member 200 to move, so that the conductive connecting member 200 on the first carrier 11 can be unfolded and laid to a connection position that fits the battery cell 300. Therefore, the battery string processing personnel can directly weld on the laid conductive connecting member 200, thereby improving the processing efficiency of the battery string.

[0147] 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 should fall within the protection scope of the appended claims of this application.
