[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on Chinese patent application number 202410239666.6, application date March 4, 2024, and invention name “Welding system, battery production line and welding method”, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into the present disclosure as a reference. Technical Field

[0003] The present disclosure relates to the field of battery technology, and in particular to a gluing system, a gluing method and a battery production line. Background Art

[0004] New energy batteries are increasingly being used in everyday life and industry. For example, new energy vehicles equipped with batteries are already widely used. Furthermore, batteries are increasingly being used in energy storage and other fields. During the battery production process, the adapters must be welded to the tabs of the bare battery cells.

[0005] In the related art, the welding equipment for welding the adapter and the tab of the bare battery cell occupies a large area, has a slow welding rhythm, and has low production efficiency. Summary of the Invention

[0006] In view of this, the embodiments of the present disclosure are intended to provide a welding system, a battery production line, and a welding method to reduce the occupied area of ​​welding equipment, increase battery production efficiency, and speed up the welding process.

[0007] To achieve the above objectives, the technical solution of the embodiment of the present disclosure is implemented as follows:

[0008] An embodiment of the present disclosure provides a welding system for welding an adapter, comprising:

[0009] The frame has a plurality of loading positions arranged at intervals, the plurality of loading positions are arranged in a direction crossing the vertical direction, at least one loading position is a welding position, and at least one loading position is a loading position;

[0010] A welding assembly is provided on the frame;

[0011] A loading assembly is movably arranged on the frame, each loading position is correspondingly provided with a loading assembly, the loading assembly is used to carry bare battery cells, and the welding assembly is used to weld the bare battery cells carried by the loading assembly located at the welding position;

[0012] The driving component can drive the loading component to move through each loading position in sequence along the first direction. Under the action of the driving component, the loading component moves from above or below the loading position along the second direction to return to the corresponding loading position. The second direction is opposite to the first direction, and the loading position is located on the side of the welding position facing the second direction.

[0013] In the embodiment of the present disclosure, the driving component can drive the component mounted on it to pass through each loading position in sequence along the first direction, and the loading component can return to the corresponding loading position along the second direction from above or below the loading position under the action of the driving component. The driving component drives the loading component to move through the loading position so that the bare cells and adapters can be loaded onto the loading component located at the loading position. The driving component drives the loading component to carry the loaded bare cells and adapters to move through the welding position, and the bare cells and adapters carried on the loading component located at the welding position are welded by the welding component. After the welding of the bare cells and adapters is completed, the loading component can return to the loading position along the second direction from above or below the loading position under the action of the driving component, thereby performing a cyclic loading and welding operation. The first direction and the second direction are arranged at intervals in the up and down directions and in opposite directions, thereby reducing the size of the frame in the width direction. During the movement of the loading component along the first direction, the bare cells carried by the loading component can be processed by related devices located on both sides of the frame, thereby reducing the occupied area of ​​the welding system. Furthermore, the loading position includes the welding position and the loading position. Multiple positions in the welding system work together, the welding rhythm is faster, and the production efficiency of the battery is increased.

[0014] In one embodiment, two adjacent loading assemblies are detachably connected, and the driving assembly includes a first transverse moving device and a second transverse moving device. The first transverse moving device can drive the loading assembly to move through each loading position in sequence along the first direction, and the second transverse moving device can be driven and connected to the loading assembly. The second transverse moving device is used to move the loading assembly along the second direction.

[0015] In the disclosed embodiment, two adjacent loading assemblies are detachably connected, and the drive assembly includes a first transverse motion device and a second transverse motion device. The first transverse motion device is capable of driving the loading assembly in a first direction, while the second transverse motion device is configured to drive the loading assembly in a second direction. Movement of the loading assembly in both the first and second directions is driven by corresponding moving components, mitigating interference between the loading assemblies during movement.

[0016] In one embodiment, the first transverse movement device can drive the loading assembly to move from the loading position along the first direction through each welding position in sequence, and the second transverse movement device is used to move the loading assembly from above or below the loading position along the second direction to return to the corresponding loading position.

[0017] In the disclosed embodiments, a first transverse motion device drives the loading assembly from the loading position through each welding position in sequence, while a second transverse motion device drives the loading assembly in a second direction back to the corresponding loading position. The loading assembly is driven by the first transverse motion device as it moves through each welding position, while the loading assembly's movement in the first direction shares a common drive device, resulting in a simple welding system with low cost.

[0018] In one embodiment, the driving assembly further includes two lifting devices, which are respectively located below the loading positions at both ends along the direction in which the loading positions are arranged, and the second transverse movement device is used to move the loading assembly from one of the lifting devices to the other lifting device along the second direction.

[0019] In the solution of the embodiment of the present disclosure, the driving assembly also includes two lifting mechanisms to enable the first transverse moving device and the second transverse moving device to form a cycle. The driving process has a high degree of automation, and the driving directions of the various components in the driving assembly are less likely to interfere, and the driving process is stable.

[0020] In one embodiment, a connecting groove and a connector that can be adapted to the connecting groove are formed at both ends of the loading assembly along the direction of arrangement of the loading positions. The connecting groove passes through the loading assembly in the up and down directions, and the connector can be moved into or out of the connecting groove in the up and down directions.

[0021] In the disclosed embodiment, the loading assembly is formed with a connecting slot and a connector. The connector can be moved vertically into or out of the connecting slot to achieve detachable connection between adjacent loading assemblies. When the loading assembly is positioned corresponding to the lifting device, the lifting device can drive the loading assembly downward, and the connector can be disengaged from the connecting slot, thereby separating the two adjacent loading assemblies. This detachable connection method is simple and low-cost. When the connector is located in the connecting slot, moving one loading assembly can also move the other loading assemblies.

[0022] In one embodiment, at least two loading positions are driving positions, which are located on the side of the welding position facing the first direction. The first transverse movement device can be detachably connected to the loading assembly located at the driving position, and the first transverse movement device is used to drive the loading assembly located at the driving position to move toward the first direction.

[0023] In the disclosed embodiment, at least two loading positions are driving positions, located on the side of the weldment facing the first direction. The first transverse movement device drives the loading assemblies located at the driving positions, thereby driving each loading assembly. The first transverse movement device is kept away from the welding positions as much as possible, which can reduce interference between the first transverse movement device and the welding assembly, thereby ensuring smoother movement of the loading assembly.

[0024] In one embodiment, the second transverse movement device includes:

[0025] a belt formed with a meshing portion;

[0026] The rotating member is used to drive the belt to move. When the lifting device drives the loading assembly to move downward, the loading assembly can engage with the engaging portion, so that the belt can drive the loading assembly to move along the second direction toward another lifting device.

[0027] In the embodiment of the present disclosure, the second transverse movement device includes a belt and a transmission member. When the lifting device drives the loading assembly downward, the loading assembly engages with the engagement portion. This engagement of the loading assembly with the engagement portion enables the loading assembly to move relatively stably along the belt in the second direction toward the other lifting device, ensuring a stable movement process.

[0028] In one embodiment, the welding system further includes a locker, which is arranged across opposite sides of the belt to clamp or release the belt, and the loading assembly includes:

[0029] A loading body is movably arranged on the frame and is used to carry the bare battery cells;

[0030] The mounting member is connected to the loading body, and the mounting member has a first coupling portion for engaging with the engaging portion. The first coupling portion is located below the loading body. When the first coupling portion engages with the engaging portion, the locker is located below the loading body, and the locker is spaced apart from the first coupling portion along the extension direction of the belt.

[0031] In an embodiment of the present disclosure, the welding system further includes a locker positioned across opposite sides of the belt to clamp or release the belt. The loading assembly includes a mounting member configured to engage with the engagement portion. The locker is capable of clamping the belt so that the mounting member of the loading assembly can more accurately engage with the engagement portion of the belt via the first engagement portion.

[0032] In one embodiment, the lock comprises:

[0033] a first clamping block, located on a side of the belt facing the engaging portion, the first clamping block having a second engaging portion for engaging with the engaging portion;

[0034] a second clamping block, located on a side of the belt facing away from the meshing portion;

[0035] The driving device is at least used to drive the first clamping block to approach or move away from the second clamping block. When the driving device drives the first clamping block to approach the second clamping block so that the second combining portion engages with the engaging portion, the lifting device drives the loading assembly downward to engage the first combining portion with the engaging portion.

[0036] In the embodiment of the present disclosure, the lock includes a first clamping block and a second clamping block. The first clamping block has a second coupling portion that engages with the engagement portion. A driving device is capable of driving the first and second clamping blocks toward each other to clamp the belt. The engagement of the second coupling portion with the engagement portion enables the lock to effectively prevent the belt from moving and, to a certain extent, reduces damage to the belt caused by the lock.

[0037] In one embodiment, there are multiple welding positions, each welding position is correspondingly provided with a welding assembly, and the multiple welding assemblies are arranged at intervals along the arrangement direction of adjacent loading positions.

[0038] In the disclosed embodiment, there are multiple welding locations, each of which is equipped with a corresponding welding assembly. The adapter and tabs require multiple welding operations to connect the two bare cells in a pair. Passing the bare cells through multiple welding locations sequentially speeds up the welding process, and multiple welding assemblies enable welding of multiple bare cells, increasing production efficiency.

[0039] In one embodiment, at least one welding assembly and the corresponding remaining welding assemblies are respectively located on both sides of the frame along a preset direction, and the preset direction is arranged to intersect with the first direction and the up-down direction.

[0040] In the embodiment of the present disclosure, at least one welding assembly and the remaining welding assemblies are respectively located on both sides of the rack along a preset direction.

[0041] In one embodiment, the welding assembly located on one side of the welding position along the preset direction is a first welding assembly, and the preset direction is arranged crosswise with the first direction and the up and down directions. The welding assembly located on the other side of the welding position along the preset direction is a second welding assembly, and the first welding assembly and the second welding assembly are arranged alternately along the first direction.

[0042] In the embodiment of the present disclosure, the first welding assembly and the second welding assembly are located on opposite sides along a preset direction, and the first welding assembly and the second welding assembly are alternately arranged along the first direction. Interference between the first welding assembly and the second welding assembly can be avoided as much as possible, and the welding process is stable.

[0043] In one embodiment, the welding system also includes a shaping component, which includes a driving member, a shaping member and two traction members. The two traction members are arranged at intervals along a preset direction, and the preset direction is arranged crosswise with the arrangement direction of two adjacent loading positions. The two ends of the shaping member are respectively connected to the two traction members. The shaping member is used to shape the pole ear. The two traction members are driven and connected to the driving member. The driving member can drive the traction member to move so that the shaping member can shape the pole ear.

[0044] In the disclosed embodiment, the welding system further includes a shaping assembly, the driving member of which is capable of driving the traction member to move, thereby driving the shaping member connected to the traction member to shape the tab. Shaping the tab can alleviate the problem of curling and folding of the tab during the placement of the bare cell in the loading assembly. The tab can be flatly attached to the adapter, making the welding process more stable and improving the product quality of the finished battery.

[0045] In one embodiment, there are two shaping assemblies, and the two shaping assemblies are arranged at intervals along the arrangement direction of two adjacent loading positions.

[0046] In the embodiment of the present disclosure, there are two shaping assemblies, and the two shaping assemblies can respectively shape the tabs of two pairs of bare battery cells. The high shaping efficiency can increase the loading speed of the bare battery cells.

[0047] In one embodiment, a driving member and a traction member are provided on opposite sides of the corresponding loading assembly along a preset direction, and a shaping member is arranged across opposite sides of the corresponding loading assembly along a preset direction. The two shaping assemblies are used to shape the tabs of two pairs of bare battery cells respectively, and the traction members corresponding to the two shaping assemblies are located between the driving members corresponding to the two shaping assemblies along the arrangement direction of the two adjacent loading positions.

[0048] In the disclosed embodiment, a corresponding loading assembly is provided with a driving member and a pulling member on opposite sides along a predetermined direction, and a shaping member is provided across two pairs of sides of the corresponding loading assembly along the predetermined direction. The shaping assembly can shape the tabs of two paired bare battery cells, increasing the shaping efficiency of the shaping assembly and thereby shortening the overall processing time.

[0049] In one embodiment, the number of shaping parts corresponding to each shaping assembly is at least two, and the arrangement direction of the at least two shaping parts corresponding to each shaping assembly is arranged along the arrangement direction of two adjacent loading positions. The driving member drives the traction member to move to drive the corresponding at least two shaping parts to move along the arrangement direction of two adjacent loading positions.

[0050] In the disclosed embodiment, there are at least two shaping members, and the spacing between the at least two shaping members corresponding to each shaping assembly is arranged along the arrangement direction of two adjacent loading positions. When the shaping members are used to shape the tabs, the shaping effect on the tabs is better, and the contact process is smoother.

[0051] In one embodiment, the shaping member is made of insulating material and is an insulating wire.

[0052] In the disclosed embodiment, the shaping member is made of an insulating material. This mitigates the risk of the shaping member causing a short circuit on the bare cell during shaping of the tab. Furthermore, the shaping member is an insulated wire, and the flexible member reduces damage to the tab.

[0053] In one embodiment, the driving assembly can drive the loading assembly to move from the loading position along the first direction through each welding position in sequence. Under the action of the driving assembly, the loading assembly moves from above or below the loading position along the second direction to return to the corresponding loading position.

[0054] In the disclosed embodiment, the loading assembly is moved from the loading position in a first direction through each welding position, and from above or below the loading position in a second direction back to the corresponding loading position, both by the drive assembly. The movement process is highly automated, which can eliminate manual operation to a certain extent.

[0055] In one embodiment, the first direction is a direction from the loading position along the arrangement direction of the plurality of loading positions to the welding position, and the first direction is arranged crosswise with the up-down direction.

[0056] In the disclosed embodiment, the first direction is the direction from the loading position to the welding position, and the first direction is arranged intersectingly with the vertical direction. The loading position and the welding position are connected by multiple loading positions arranged substantially along the first direction. This can minimize the distance traveled from the loading position to the welding position, thereby improving the processing efficiency.

[0057] In one embodiment, the loading assemblies corresponding to the multiple loading positions are connected in sequence.

[0058] In the disclosed embodiment, the loading assemblies corresponding to the multiple loading positions are connected in sequence. By driving any one of the sequentially connected loading assemblies, the multiple loading assemblies can be driven to move synchronously, and the position setting of the driving assembly can be relatively flexible.

[0059] The present disclosure also provides a battery production line, including:

[0060] Welding systems of any of the above;

[0068] Lift the loading assembly to the loading position through the corresponding lifting device;

[0069] The first direction is opposite to the second direction.

[0070] In the disclosed embodiment, the loading position cycles vertically along the first and second directions using a first transverse movement mechanism, a second transverse loading mechanism, and two lifting mechanisms. The first and second transverse positions are spaced vertically apart, reducing the width of the welding assembly. While the loading assembly moves in the first direction, the bare cells carried by the loading assembly can be welded by the welding assemblies located on both sides of the frame, thereby reducing the footprint of the welding system.

DETAILED DESCRIPTION

[0102] The following embodiments of the technical solution of the present disclosure are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present disclosure and are therefore only examples and are not intended to limit the scope of protection of the present disclosure.

[0103] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this disclosure; the terms "including" and "having" of the embodiments of this disclosure and any variations thereof are intended to cover non-exclusive inclusions.

[0104] In the description of the embodiments of the present disclosure, technical terms such as "first," "second," and "third" are used solely to distinguish different objects and should not be understood to indicate or imply relative importance or to implicitly specify the quantity, specific order, or primary and secondary relationship of the technical features indicated. In the description of the embodiments of the present disclosure, "plurality" means more than two, unless otherwise specifically defined.

[0105] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present disclosure. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0106] In the description of the embodiments of the present disclosure, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0107] In the description of the embodiments of the present disclosure, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal connectivity between two components or interaction between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present disclosure based on specific circumstances.

[0108] In the description of the embodiments of the present disclosure, unless otherwise clearly specified and limited, the technical term "contact" should be understood in a broad sense, and can be direct contact, contact through an intermediate medium layer, contact with essentially no interaction force between the two contacting parties, or contact with interaction force between the two contacting parties.

[0109] As part of the creative concept of the present disclosure, before describing the embodiments of the present disclosure, it is necessary to analyze the reasons why the welding equipment for welding the adapter and the tabs of the bare battery cell in the related art occupies a large area, as well as the reasons for the slow welding rhythm and low production efficiency, and obtain the technical solution of the embodiments of the present disclosure through reasonable analysis.

[0110] In the related art, the loading assembly usually moves in a circular motion on an approximately horizontal plane, and the welding assembly is arranged on one side or both sides of the loading assembly, which further increases the occupied area of ​​the welding system. When the welding assembly is arranged on both sides of the moving direction of the loading assembly, since the spacing between the forward transport line and the return transport line of the loading assembly is short, the welding assembly cannot be arranged between the forward transport line and the return transport line, so the welding assembly needs to be arranged on both sides of the forward transport line and the return transport line along the width direction, so the occupied area of ​​the welding system is larger. In the related art, the adapter and the bare cell are loaded and welded at the same loading position. During the loading process of the adapter and the bare cell, it is almost impossible to weld the adapter and the bare cell. During the welding process of the adapter and the bare cell, it is almost impossible to load the adapter and the bare cell. Loading and welding cannot be carried out simultaneously. Therefore, the welding rhythm of the entire welding system is slow and the production efficiency is low.

[0111] The present disclosure drives the loading assembly 3 to move along the first direction 2a through each loading position 1a through the driving assembly 4, and then moves the loading assembly 3 from below the loading position 1a along the second direction 2b to return to the corresponding loading position 1a, thereby saving the occupied area of ​​the welding system.

[0112] In a first aspect of an embodiment of the present disclosure, there is provided a welding system, please refer to Figures 1 to 5, the welding system is used for welding adapters, and includes: a frame 1, a welding assembly 2, a loading assembly 3 and a driving assembly 4. The frame 1 has a plurality of loading positions 1a arranged at intervals, and the arrangement direction of the plurality of loading positions 1a is arranged crosswise with the up and down direction 2c. At least one loading position 1a is a welding position 1b, and at least one loading position 1a is a loading position. The welding assembly 2 is arranged on the frame 1. The loading assembly 3 is movably arranged on the frame 1, and each loading position 1a is correspondingly provided with a loading assembly 3. The loading assemblies 3 corresponding to the plurality of loading positions 1a are connected in sequence. The loading assembly 3 is used to carry bare battery cells 5, and the welding assembly 2 is used to weld the bare battery cells 5 carried by the loading assembly 3 located at the welding position 1b. The driving component 4 can drive the loading component 3 to move along the first direction 2a through each loading position 1a in sequence. Under the action of the driving component 4, the loading component 3 moves from the bottom of the loading position 1a along the second direction 2b to return to the corresponding loading position 1a. The second direction 2b is opposite to the first direction 2a, and the loading position is located on the side of the welding position 1b facing the second direction 2b.

[0113] The frame 1 is the main supporting structure of the welding system, and other mechanisms of the welding system are basically mainly supported by the frame 1.

[0114] Exemplarily, the frame 1 is a bracket formed by welding section steel.

[0115] Exemplarily, the frame 1 may be integrally formed.

[0116] The welding assembly 2 is a component in the welding system that mainly performs the welding function, and the bare battery cell 5 and the adapter are welded through the welding assembly 2 .

[0117] For example, the welding assembly 2 includes a welding gun for welding.

[0118] Exemplarily, the welding assembly 2 further includes a driving mechanism for driving the welding gun to move to a corresponding welding position.

[0119] Exemplarily, the driving mechanism may be a motor.

[0120] The loading assembly 3 is a structure in the welding system mainly used to support the bare battery cell 5 and / or the adapter.

[0121] Exemplarily, the loading component 3 may be a tray.

[0122] The driving assembly 4 is a structure that provides power for the movement of the loading assembly 3 in the welding system.

[0123] For example, the driving component 4 may be one or more motors.

[0124] For example, the driving assembly 4 may be one or more cylinders.

[0125] The direction in which the plurality of loading positions 1a are arranged is intersecting with the up-down direction 2c. For example, referring to Figures 1 and 14, the direction in which the plurality of loading positions 1a are arranged is perpendicular to the up-down direction 2c.

[0126] In one embodiment, referring to Figures 1 to 6 and Figures 13 to 16, a welding system is used to weld adapters, and includes: a frame 1, a welding assembly 2, a loading assembly 3, and a driving assembly 4. The frame 1 has a plurality of loading positions 1a arranged at intervals, and the arrangement direction of the plurality of loading positions 1a is arranged crosswise with the up and down direction 2c. At least one loading position 1a is a welding position 1b, and at least one loading position 1a is a loading position. The welding assembly 2 is provided on the frame 1. The loading assembly 3 is movably provided on the frame 1, and each loading position 1a is correspondingly provided with a loading assembly 3. The loading assembly 3 is used to carry bare battery cells 5, and the welding assembly 2 is used to weld the bare battery cells 5 carried by the loading assembly 3 located at the welding position 1b. The driving component 4 can drive the loading component 3 to move in sequence along the first direction 2a through each loading position 1a. Under the action of the driving component 4, the loading component 3 moves from above or below the loading position 1a along the second direction 2b to return to the corresponding loading position 1a. The second direction 2b is opposite to the first direction 2a, and the loading position is located on the side of the welding position 1b facing the second direction 2b.

[0127] The frame 1 is the main supporting structure of the welding system, and other mechanisms of the welding system are basically mainly supported by the frame 1.

[0128] Exemplarily, the frame 1 is a bracket formed by welding section steel.

[0129] Exemplarily, the frame 1 may be integrally formed.

[0130] The welding assembly 2 is a component in the welding system that mainly performs the welding function, and the bare battery cell 5 and the adapter are welded through the welding assembly 2 .

[0131] For example, the welding assembly 2 includes a welding gun for welding.

[0132] Exemplarily, the welding assembly 2 further includes a driving mechanism for driving the welding gun to move to a corresponding welding position.

[0133] Exemplarily, the driving mechanism may be a motor.

[0134] The loading assembly 3 is a structure in the welding system mainly used to support the bare battery cell 5 and / or the adapter.

[0135] Exemplarily, the loading component 3 may be a tray.

[0136] The driving assembly 4 is a structure that provides power for the movement of the loading assembly 3 in the welding system.

[0137] For example, the driving component 4 may be one or more motors.

[0138] For example, the driving assembly 4 may be one or more cylinders.

[0139] Exemplarily, there are two loading positions, the loading position corresponding to the drive component 4 is the first loading position 1e, and the other loading position is the second loading position 1f. The second loading position 1f is located between the first loading position 1e and the welding position 1b. The first loading position 1e is used for loading the adapter sheet, and the second loading position 1f is used for loading the bare battery cell 5.

[0140] The multiple loading positions 1a are arranged in a substantially parallel bidirectional direction. For example, referring to Figures 1 and 14 , the multiple loading positions 1a are arranged in the left-right direction as shown. That is, the multiple loading positions 1a are arranged in the left-right direction as shown.

[0141] The first direction 2a is one of the directions in which the plurality of loading positions 1a are arranged. For example, with reference to Figures 1 and 14 , the first direction 2a is the leftward direction as shown, meaning that the drive assembly 4 can drive the loading assembly 3 to sequentially move leftward through each loading position 1a as shown.

[0142] The second direction 2b is another direction in the direction in which the plurality of loading positions 1a are arranged. For example, with reference to FIG1 and FIG14 , the second direction 2b is a rightward direction as shown in the figure, i.e., the loading assembly 3 moves rightward as shown in the figure from above or below the loading position 1a under the action of the driving assembly 4 to return to the loading position.

[0143] Exemplarily, referring to FIG. 1 and FIG. 14 , the first direction 2 a is arranged orthogonal to the up-down direction 2 c.

[0144] Exemplarily, the battery cell includes a shell, an end cover and a bare cell 5 . The end cover can be covered on the shell, and the bare cell 5 is arranged in the shell.

[0145] Exemplarily, the battery cell further includes a conductive terminal and a switching piece. The conductive terminal is provided on the end cover. The switching piece is respectively connected to the conductive terminal and the tab 5a of the bare cell 5 to make the tab 5a electrically conductive with the conductive terminal.

[0146] Exemplarily, the conductive terminal is a pole.

[0147] For example, the loading assembly 3 can move along the second direction from below the loading position under the action of the driving assembly, thereby reducing the possibility that the loading assembly 3 moving along the second direction interferes with the loading assembly 3 located at the loading position.

[0148] For example, the loading assembly 3 can return to the loading position along the second direction from below the loading position under the action of the driving assembly.

[0149] Exemplarily, the loading assembly 3 can move along the second direction from above the loading position under the action of the driving assembly.

[0150] For example, the loading assembly 3 can return to the loading position along the second direction from above the loading position under the action of the driving assembly.

[0151] In the embodiment of the present disclosure, the driving component 4 can drive the component mounted on it to pass through each loading position 1a in sequence along the first direction 2a, and the loading component 3 can return to the corresponding loading position 1a along the second direction 2b from above or below the loading position 1a under the action of the driving component 4. The first direction 2a and the second direction 2b are arranged at intervals along the up and down direction 2c and in opposite directions, which reduces the size of the frame 1 in the width direction. In the process of the loading component 3 moving along the first direction 2a, the bare battery cell 5 carried by the loading component 3 can be processed by related devices located on both sides of the frame 1, thereby reducing the occupied area of ​​the welding system. Furthermore, the loading position 1a includes a welding position 1b and a loading position. Multiple stations in the welding system work together, the welding rhythm is faster, and the production efficiency of the battery is increased.

[0152] Exemplarily, the width direction of the frame 1 is arranged to intersect both the first direction 2 a and the up-down direction 2 c.

[0153] Exemplarily, referring to FIG. 1 , the width direction of the rack 1 is perpendicular to both the first direction 2 a and the up-down direction 2 c.

[0154] In one embodiment, please refer to Figure 1, two adjacent loading assemblies 3 are detachably connected, and the driving assembly 4 includes a first transverse movement device 40 and a second transverse movement device 41.

[0155] The first transverse movement device 40 is mainly a structure for providing power for the loading assembly 3 to move along the first direction.

[0156] Exemplarily, the first transverse movement device 40 drives the loading assembly 3 located at the loading position 1 a to move along the first direction.

[0157] Exemplarily, the first transverse movement device 40 is a cylinder or a motor.

[0158] For example, please refer to Figure 6, the second transverse movement device 41 includes a belt 411 and a rotating member 410, the rotating member 410 is used to drive the belt 411 to move, and the belt 411 is formed with an engaging portion 411a. When the lifting device drives the loading component 3 to move downward, the loading component 3 can engage with the engaging portion 411a, so that the belt 411 can drive the loading component 3 to move along the second direction 2b toward another lifting device.

[0159] Exemplarily, the belt 411 is a synchronous belt.

[0160] Exemplarily, the second transverse movement device 41 may be a rack and pinion transmission.

[0161] In the disclosed embodiment, two adjacent loading assemblies 3 are detachably connected, and the drive assembly 4 includes a first transverse movement device 40 and a second transverse movement device 41. The first transverse movement device 40 is capable of driving the loading assembly 3 in a first direction 2a, while the second transverse movement device 41 is used to drive the loading assembly 3 in a second direction 2b. The movement of the loading assembly 3 in both the first direction 2a and the second direction 2b is driven by corresponding moving components, mitigating interference with the movement of the loading assembly 3.

[0162] It is understandable that the embodiments of the present disclosure do not limit the structure of the drive assembly 4. The drive assembly 4 may also include a third transverse movement device. The first transverse movement device 40 and the third transverse movement device jointly drive the loading assembly 3 to move through each loading position 1a in sequence along the first direction 2a.

[0163] In one embodiment, please refer to Figure 4, the first transverse movement device 40 can drive the loading component 3 to move from the loading position along the first direction 2a through each welding position 1b in sequence, and the second transverse movement device 41 is used to move the loading component 3 from above or below the loading position 1a along the second direction 2b to return to the corresponding loading position.

[0164] In the embodiment of the present disclosure, the first transverse motion device 40 is capable of driving the loading assembly 3 from the loading position through each welding position 1b in sequence, and the second transverse motion device 41 is capable of driving the loading assembly 3 in the second direction 2b to return to the corresponding loading position. The loading assembly 3 is driven by the first transverse motion device 40 as it moves through each welding position 1b, and the movement of the loading assembly 3 in the first direction 2a shares the same drive device 92, resulting in a simple welding system structure and low cost.

[0165] It is understood that the embodiments of the present disclosure are not limited to the loading assembly 3 being moved sequentially from the loading position along the first direction 2a through each welding position 1b. For example, the first transverse movement device 40 drives the loading assembly 3 from the loading position along the first direction 2a through some welding positions 1b, and the second transverse movement device 41 drives the loading assembly 3 through the remaining welding positions 1b.

[0166] In one embodiment, referring to FIG1 , the driving assembly 4 further includes two lifting devices, which are respectively located below the loading positions 1a at both ends of the direction in which the loading positions 1a are arranged, and the second transverse movement device 41 is used to move the loading assembly 3 from one of the lifting devices to the other lifting device along the second direction 2b.

[0167] The lifting device is a structure that can be driven to rise or fall.

[0168] Exemplarily, the loading assembly 3 is raised or lowered by the lifting device, so that the device assembly 3 can be transferred from the loading position 1a to the bottom of the loading position 1a, or the device assembly 3 can be transferred from the bottom of the loading position 1a to the loading position.

[0169] For example, referring to FIG1 , one of the lifting devices is located below the first loading position 1 e .

[0170] For example, referring to FIG. 1 , the lifting device below the first loading position 1 e is a first lifting device 42 , and the other lifting device is a second lifting device 43 .

[0171] Exemplarily, the lifting device includes a lifting cylinder and a carrying platform. When the loading assembly 3 is located on the carrying platform, the lifting cylinder can drive the carrying platform to move up or down.

[0172] Exemplarily, the lifting device is a lifting cylinder.

[0173] For example, the lifting device may be a screw rod pair structure that drives the lifting.

[0174] In the solution of the embodiment of the present disclosure, the driving component 4 also includes two lifting mechanisms, so that the loading component 3 can be switched more conveniently between the loading position 1a and above or below the loading position 1a, so that the first transverse movement device 40 and the second transverse movement device 41 form a cycle. The driving process has a high degree of automation, and the driving directions of the various components in the driving component 4 are less likely to interfere, and the driving process is stable.

[0175] It is understood that the embodiment of the present disclosure is not limited to the drive assembly 4 further comprising two lifting devices. Exemplarily, the drive assembly 4 further comprises a mechanical gripper, which is used to grab the corresponding loading assembly 3 and move it to the second transverse movement device 41.

[0176] In one embodiment, referring to Figures 4 and 5, a connecting groove 3a and a connector 3b that can be adapted to the connecting groove 3a are respectively formed at both ends of the loading assembly 3 along the direction in which the loading positions 1a are arranged. The connecting groove 3a passes through the loading assembly 3 along the up-down direction 2c, and the connector 3b can move into or out of the connecting groove 3a along the up-down direction 2c.

[0177] In the disclosed embodiment, the loading assembly 3 is formed with a connecting groove 3a and a connector 3b. The connector 3b can be moved in and out of the connecting groove 3a along the vertical direction 2c to achieve a detachable connection between adjacent loading assemblies 3. When the loading assembly 3 is located in the corresponding position of the lifting device, the lifting device can drive the loading assembly 3 to descend, and the connector 3b can be disengaged from the connecting groove 3a, thereby separating the two adjacent loading assemblies 3. This detachable connection method is simple and low-cost. When the connector 3b is located in the connecting groove 3a, moving one loading assembly 3 can also move the other loading assemblies 3.

[0178] It is understood that the embodiments of the present disclosure are not limited to adjacent loading assemblies 3 being detachably connected by the connection groove 3a and the plug-in connector 3b. In one embodiment, adjacent loading assemblies 3 are detachably connected by a magnetic member.

[0179] In one embodiment, please refer to Figures 1, 3 and 4, at least two loading positions 1a are driving positions, the driving position is located on the side of the welding position 1b facing the first direction 2a, and the first transverse movement device 40 can be detachably connected to the loading assembly 3 located at the driving position, and the first transverse movement device 40 is used to drive the loading assembly 3 located at the driving position to move toward the first direction 2a.

[0180] For example, there are two driving stations: the one closest to the welding station 1b is the first driving station 1c, and the other driving station is the second driving station 1d. The loading assembly 3 located in the first driving station 1c is connected to the first transverse movement device 40, which is capable of moving the loading assembly 3 located in the first driving station 1c to the second driving station 1d. When the first transverse movement device 40 moves the loading assembly 3 to the second driving station 1d, the first transverse movement device 40 disengages from the loading assembly 3. A lifting device is located below the second driving station 1d, and the lifting device is capable of moving the loading assembly 3 located in the second driving station 1d toward the second transverse movement device 41.

[0181] In the disclosed embodiment, at least two loading positions 1a are driving positions, located on the side of the weldment facing the first direction 2a. The first transverse movement device 40 drives the loading assemblies 3 located at the driving positions, thereby driving each loading assembly 3. The first transverse movement device 40 is as far away from the welding position 1b as possible, which can reduce interference between the first transverse movement device 40 and the welding assembly 2, making the movement of the loading assembly 3 smoother.

[0182] It is understood that the present disclosure is not limited to at least two loading positions 1a being driving positions. In one embodiment, the first transverse movement device 40 directly drives the loading assembly 3 located at the welding position 1b or the loading position to move along the first direction 2a. In another embodiment, one of the lifting devices is located below the welding position 1b, which is farthest from the loading position. After the bare cells 5 carried by the loading assembly 3 are welded, the lifting device drives the bare cells 5 downward.

[0183] In one embodiment, as shown in FIG15 , the second transverse movement device 41 includes a belt 411 and a rotating member 410. The belt 411 is formed with an engaging portion 411a. The rotating member 410 is used to drive the belt 411. When the lifting device drives the loading assembly 3 downward, the loading assembly 3 engages with the engaging portion 411a, allowing the belt 411 to drive the loading assembly 3 along the second direction 2b toward the other lifting device.

[0184] The belt 411 is a belt-driven conveying structure, and the belt 411 is mainly used to drive the loading assembly 3 below the loading position 1a to move.

[0185] The belt 411 is a synchronous belt or a V-belt.

[0186] The rotating member 410 is a structure that provides power to the belt. The belt is driven to move by the friction between the rotating member 410 and the belt.

[0187] Exemplarily, the rotating member 410 is a pulley that cooperates with the belt 411 .

[0190] In the embodiment of the present disclosure, the second transverse movement device 41 includes a belt 411 and a rotating member 410. When the lifting device drives the loading assembly 3 downward, the loading assembly 3 engages with the engagement portion 411a. This engagement between the loading assembly 3 and the engagement portion 411a allows the loading assembly 3 to move relatively stably along the belt 411 in the second direction 2b toward the other lifting device, ensuring a stable movement process.

[0191] It is understandable that the embodiment of the present disclosure does not limit whether the belt 411 is formed with the engaging portion 411 a , and the loading assembly 3 can be connected to the belt 411 through friction.

[0192] In one embodiment, referring to FIG15 , the welding system further includes a locker 9, which is arranged across opposite sides of the belt 411 to clamp or release the belt 411. The loading assembly 3 includes a loading body 30 and a mounting member 31. The loading body 30 is movably arranged on the frame 1 and is used to carry the bare battery cells 5. The mounting member 31 is connected to the loading body 30 and has a first coupling portion 31a for engaging with the engaging portion 411a. The first coupling portion 31a is located below the loading body 30. When the first coupling portion 31a engages with the engaging portion 411a, the locker 9 is located below the loading body 30 and is spaced apart from the first coupling portion 31a along the extension direction of the belt 411.

[0193] The locker 9 refers to components that can be locked together.

[0194] For example, the lock 9 drives the two clamping blocks to move closer to or away from each other through a cylinder to lock or unlock the lock.

[0195] For example, the locker 9 can drive the two clamping blocks to move closer to or away from each other through a screw pair so that the locker is locked or unlocked.

[0196] The loading body 30 is used to carry the main components of the bare battery cell 5 .

[0202] In the embodiment of the present disclosure, the welding system further includes a lock 9, which is positioned across opposite sides of the belt 411 to clamp or release the belt 411. The loading assembly 3 includes a mounting member 31, which is configured to engage with the engagement portion 411a. The lock 9 can clamp the belt 411, allowing the mounting member 31 of the loading assembly 3 to more accurately engage with the engagement portion 411a of the belt 411 via the first engagement portion 31a.

[0203] It can be understood that the embodiments of the present disclosure do not limit whether the welding system is provided with the locker 9 .

[0204] In one embodiment, referring to FIG15 , the locker 9 includes a first clamping block 90, a second clamping block 91, and a driving device 92. The first clamping block 90 is located on the side of the belt 411 facing the meshing portion 411a. The first clamping block 90 has a second coupling portion 90a for engaging with the meshing portion 411a. The second clamping block 91 is located on the side of the belt 411 facing away from the meshing portion 411a. The driving device 92 is at least used to drive the first clamping block 90 toward or away from the second clamping block 91. When the driving device 92 drives the first clamping block 90 toward the second clamping block 91 so that the second coupling portion 90a engages with the meshing portion 411a, the lifting device drives the loading assembly 3 downward so that the first coupling portion 31a engages with the meshing portion 411a.

[0205] The first clamping block 90 is a structure for clamping the belt 411 and is used to cooperate with the second clamping block 91 to clamp the belt 411. The second coupling portion 90a is engaged with the engaging portion 411a to limit the movement of the belt 411.

[0206] Exemplarily, the first clamping block 90 is square in shape.

[0215] In the embodiment of the present disclosure, the locker 9 includes a first clamping block 90 and a second clamping block 91. The first clamping block 90 has a second coupling portion 90a that engages with the engagement portion 411a. The driving device 92 is capable of driving the first clamping block 90 and the second clamping block 91 toward each other to clamp the belt 411. The engagement of the second coupling portion 90a with the engagement portion 411a enables the locker to effectively prevent the movement of the belt 411 and can reduce damage to the belt 411 caused by the locker 9 to a certain extent.

[0216] It is understood that the present disclosure does not limit whether the first clamping block 90 is formed with the second coupling portion 90a. For example, the first clamping block 90 and the second clamping block 91 approach each other to clamp the belt 411, and the first clamping block 90 and the second clamping block 91 provide friction by squeezing to prevent the belt 411 from moving.

[0217] In one embodiment, referring to FIG. 4 , there are multiple welding positions 1 b , each of which is provided with a corresponding welding assembly 2 , and the multiple welding assemblies 2 are arranged at intervals along the arrangement direction of adjacent loading positions 1 a .

[0219] Exemplarily, the first welding position 1g1b is adjacent to the loading position.

[0220] Exemplarily, the second welding position 1h1b is adjacent to the driving position.

[0221] In the disclosed embodiment, there are multiple welding positions 1b, each of which is provided with a corresponding welding assembly 2. The adapter and the tab 5a require multiple welding operations to connect the two bare cells 5 in a pair. Passing the bare cells 5 sequentially through multiple welding positions 1b can speed up the welding process, and multiple welding assemblies 2 can weld multiple bare cells 5, increasing production efficiency.

[0222] It is understood that the embodiments of the present disclosure do not limit the number of welding positions 1 b. For example, the number of welding positions 1 b is single, and a single welding assembly 2 is used to weld the bare cell 5 located at the welding position 1 b.

[0229] It is understood that the embodiment of the present disclosure is not limited to at least one welding assembly 2 and the remaining welding assemblies 2 being located on both sides of the frame 1 along the preset direction 2d. In one embodiment, all welding assemblies 2 are located on a single side of the frame 1 along the preset direction 2d.

The first welding assembly 202 and the second welding assembly 212 are arranged alternately along the first direction 2a. This minimizes interference between the first welding assembly 202 and the second welding assembly 212, ensuring a stable welding process. The alternating arrangement of the first welding assembly 202 and the first welding assembly 212 on opposite sides of the predetermined direction 2d results in a more compact arrangement of the multiple welding assemblies 2 along the first direction.

While the loading assembly 3 moves along the first direction 2a, the bare cells 5 carried by the loading assembly 3 can be welded by the welding assemblies 2 located on both sides of the frame 1, thereby reducing the occupied area of ​​the welding system.

[0285] In one embodiment, referring to FIG8 , the welding method further includes:

[0286] Step S7: When the bare cell is located above the corresponding loading position, the tabs of the bare cell are shaped by a shaping assembly;

[0294] In the disclosed embodiment, the driving member 60 drives the pulling member 62 to move along the arrangement direction of the adjacent loading positions 1a so that the shaping member 61 can shape the tabs 5a. The shaping process is relatively convenient and simple. The shaping member 61 can shape the two tabs 5a of the bare battery cell 5 along the arrangement direction of the two pulling members 62.
