Current technologies typically involve transferring cells with insufficient electrolyte from a temporary storage station to the entrance of the electrolyte injection station. This replenishment process is complex, involves a long transport distance, and requires a large footprint for the electrolyte injection mechanism. Furthermore, there are safety risks associated with electrolyte injection errors, cell drops, and stacking during transport, indicating room for improvement. Summary of the Invention

Through the combined use of various magnetic drive structures and fixtures, automated battery conveying and processing can be achieved, reducing the risk of battery damage and thus improving production efficiency. At the same time, the setting of the transfer channel and the transfer magnetic drive structure can flexibly adjust the battery conveying path to meet different processing requirements.

[0013] In some embodiments, the first magnetic drive structure and the finishing magnetic drive structure are both used to drive a plurality of the fixtures, and the transfer magnetic drive structure is used to drive a single fixture.

[0014] In the above technical solution, multiple fixtures are driven by the first magnetic drive structure and the supplementary processing magnetic drive structure, and a single fixture is driven by the transfer magnetic drive structure. This allows for the efficient processing of a large number of batteries during the liquid injection and replenishment at the processing station, thereby improving the production efficiency of the processing station. It also allows for precise control of the movement of a single fixture at the transfer station.

[0015] In some embodiments, the processing conveyor line and the transfer channel are both arranged to intersect with the logistics conveyor line, and the processing conveyor line and the transfer channel are arranged parallel and spaced apart; the supplementary processing waiting station is arranged parallel and spaced apart from the logistics conveyor line.

[0016] In the above technical solution, efficient battery transport and transfer can be achieved through cross-laid processing conveyor lines and transfer channels, as well as parallel and spaced supplementary processing waiting stations. Furthermore, the cross-layout and different magnetic drive structures allow batteries to be flexibly transferred between different conveyor lines and stations. Through a rational layout and efficient automated processing flow, production efficiency can be improved, production costs reduced, and battery quality and stability enhanced.

[0017] In some embodiments, the logistics conveyor line includes: bridging positions and post-verification stations, the processing conveyor line and the logistics conveyor line are intersected at the bridging positions, the post-verification stations are located downstream of all the bridging positions, and the transfer stations are located downstream of the post-verification stations.

[0018] In the above technical solution, through reasonable cross-layout and efficient automated processing, batteries can be transferred between different conveyor lines and workstations, significantly improving production efficiency, reducing production costs, and helping to improve battery quality and stability.

[0019] In some embodiments, there are multiple processing conveyor lines, which are spaced apart along the length of the logistics conveyor line, and the supplementary processing waiting station is connected to the processing station closest to the transfer station.

[0020] In the above technical solution, the battery processing path can be flexibly adjusted and supplementary processing needs can be met by setting up multiple processing conveyor lines and supplementary processing waiting stations. At the same time, through reasonable layout and efficient automated processing, production efficiency can be improved and production costs can be reduced.

[0025] In some embodiments, the processing equipment is a liquid injection device for injecting liquid into the battery located at the processing station.

[0026] In the above technical solution, the efficient operation of the battery processing system can be achieved through the coordinated work between the battery delivery system and the liquid injection equipment.

[0027] Thirdly, embodiments of this application provide a battery production line, including: the battery production line as described above.

By realizing the automated control of the battery production line, the production process can be optimized and production efficiency and quality can be improved.

[0029] Fourthly, embodiments of this application provide a battery processing method, including:

[0030] The processing results of the processed batteries are checked at the post-checking station of the logistics conveyor line to identify target batteries that do not meet the target conditions.

[0031] Once it is determined that the target battery has been transported to the transfer station, the transfer magnetic drive structure is controlled to move along the transfer channel to the supplementary processing waiting station.

[0032] The magnetic drive structure for reprocessing is controlled to transport the battery located at the reprocessing waiting station to the processing station;

[0033] Control the processing equipment to process the battery located at the processing station.

[0034] In the above technical solution, by introducing automated components such as logistics conveyor lines, transfer magnetic drive structures and processing equipment, the battery processing and transfer process can be automated and optimized, thereby improving the efficiency and quality of battery processing.

[0035] In some embodiments, after controlling the transfer magnetic drive structure to move along the transfer channel to the supplementary processing waiting station, the method further includes: controlling the transfer magnetic drive structure to move along the transfer channel to the transfer station so that other processed batteries can pass through.

[0036] In the above technical solution, the method can achieve a more flexible and efficient battery transfer process in terms of motion control of the transfer magnetic drive structure. By optimizing the transfer process, the transfer magnetic drive structure can quickly return to the transfer station after completing a transfer task, ready to perform bridging or the next transfer, thereby improving the overall efficiency of battery processing.

[0037] In some embodiments, when the processing equipment is used to process multiple batteries, controlling the supplementary processing magnetic drive structure to transport the battery located at the supplementary processing waiting station to the processing station includes:

[0038] If the number of batteries located at the supplementary processing waiting station is equal to the single processing capacity of the processing equipment, the supplementary processing magnetic drive structure is controlled to transport the batteries located at the supplementary processing waiting station to the processing station.

[0039] In the above technical solution, this method, combined with the single processing capacity of the processing equipment, can achieve a more refined battery transfer and processing flow. By optimizing the transfer and processing flow, waiting time and resource waste can be reduced, and the overall efficiency of battery processing can be improved.

[0040] In some embodiments, when the number of batteries at the supplementary processing waiting station is less than the single processing capacity of the processing equipment, the processing equipment corresponding to the processing station connected to the supplementary processing waiting station is used to process the batteries transported by the processing conveyor line.

[0041] In the above technical solution, when the number of batteries waiting for replenishment at the processing station is insufficient, this method can flexibly adjust the processing objects of the processing equipment, reduce waiting time and resource waste, and improve the continuity and efficiency of the production line.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0053] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0055] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0056] The battery mentioned in the embodiments of this application refers to a single battery cell, which includes a casing, electrode assembly, and electrolyte. The casing is used to house the electrode assembly and electrolyte. The electrode assembly consists of a positive electrode, a negative electrode, and a separator. The battery cell mainly relies on the movement of metal ions between the positive and negative electrode plates to function. The positive electrode includes a positive current collector and a positive active material layer. The positive active material layer is coated on the surface of the positive current collector, and the positive current collector without the positive active material layer protrudes from the positive current collector with the positive active material layer, serving as the positive electrode tab. Taking a lithium-ion battery as an example, the material of the positive current collector can be aluminum, and the positive active material can be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc. The negative electrode includes a negative current collector and a negative active material layer. The negative active material layer is coated on the surface of the negative current collector, and the negative current collector without the negative active material layer protrudes from the one with the negative active material layer. The negative current collector without the negative active material layer serves as the negative electrode tab.

[0059] In recent years, new energy vehicles have experienced rapid development. In the field of electric vehicles, the power battery, as the power source, plays an irreplaceable and crucial role. A battery pack consists of a casing and multiple individual battery cells housed within it. Among these, the battery, as a core component of new energy vehicles, has high requirements in terms of both safety and cycle life.

[0060] In the battery production process, insufficient electrolyte injection can occur, requiring automatic replenishment. The inventors discovered that current technologies typically involve transferring batteries with insufficient electrolyte from a temporary storage station to the entrance of the electrolyte injection station. This process is complex, involves long battery transport distances, and requires a large overall footprint for the electrolyte injection mechanism. Furthermore, the batteries pose safety risks during transport, including incorrect replenishment, dropping, and stacking. Therefore, improvements are needed.

[0061] Based on the above considerations, and to address the issues of complex battery replenishment processes and safety risks during battery transport, the inventors, through in-depth research, designed a battery delivery system, a battery processing system, a battery production line, and a battery processing method. This battery delivery system, with its unique structure, solves the problems of complex battery replenishment processes and safety risks during battery transport. Furthermore, it reduces the overall footprint of the battery delivery system and eliminates mechanical obstruction and sensing mechanisms, helping to reduce electrolyte splashing caused by impacts or inductive speed changes in the transport mechanism.

[0062] For ease of explanation, the following embodiments use a battery conveying system, battery processing system, battery production line, and battery processing method from the present application as examples.

[0063] As shown in Figures 1-6, Figure 1 is a schematic diagram of the structure of a battery delivery system 10 according to one embodiment of this application. Figure 2 is a schematic diagram of the structure of a battery delivery system 10 according to one embodiment of this application. Figure 3 is a schematic diagram of the structure of a battery delivery system 10 according to one embodiment of this application. Figure 4 is a schematic diagram of the structure of a battery delivery system provided in some embodiments of this application. Figure 5 is a schematic diagram of the structure of the fixture 130 of a battery delivery system 10 according to one embodiment of this application. Figure 6 is a partial enlarged view of point A in Figure 5. This application provides a battery delivery system 10, which includes: a logistics conveyor line 110, a processing conveyor line 120, a replenishment processing waiting station 155, a transfer channel 170, and a fixture 130, to solve the problems of complex battery 160 replenishment process and safety risks in battery 160 transfer process.

[0064] The logistics conveyor line 110 includes a plurality of first magnetic drive structures 111 arranged in sequence and at least one transfer magnetic drive structure 114 located at the transfer station 153. The plurality of first magnetic drive structures 111 arranged in sequence on the logistics conveyor line 110 can form a continuous conveying path. The magnetic drive structure drives the clamp 130 by magnetic force, so that the clamp 130 moves along the logistics conveyor line 110. At the same time, the transfer station 153 is set on the logistics conveyor line 110 to transfer the clamp 130 and the battery 160 on the clamp 130 from one conveying path to another path or device.

[0065] Meanwhile, the transfer station 153 is equipped with a transfer magnetic drive structure 114, which is mainly used to drive a specific fixture 130 on the transfer channel 170. The processing conveyor line 120 is connected to the logistics conveyor line 110 and at least one processing station 140. The main function of the processing conveyor line 120 is to transport the battery 160 to be processed from the logistics conveyor line 110 to the processing station 140 for processing. The replenishment waiting station 155 is connected to one of the processing stations 140 and is used to store the battery 160 that needs to be replenished with electrolyte. The replenishment waiting station 155 is equipped with a replenishment magnetic drive structure 115, which is used to drive the fixture 130 so that the battery 160 can move between the replenishment waiting station 155 and the processing station 140.

[0066] The transfer channel 170 connects the transfer station 153 and the supplementary processing waiting station 155, forming a passage that allows the fixture 130 and the battery 160 on the fixture 130 to move quickly between the two positions. At the same time, the transfer magnetic drive structure 114 is movably installed in the transfer channel 170 and can move along the transfer channel 170 to adapt to different transfer needs.

[0067] As shown in Figures 3-5, the fixture 130 includes a magnetic component 131 and a support component 132 for carrying the battery 160. The magnetic component 131 interacts with the magnetic drive structure to drive the fixture 130 to move. The support component 132 carries the battery 160 to keep the battery 160 stable during transportation and processing. The magnetic drive structure includes a first magnetic drive structure 111, a transfer magnetic drive structure 114, and a supplementary processing magnetic drive structure 115, all of which drive the fixture 130 through the magnetic component 131.

[0068] For example, processing conveyor line 120 is connected between logistics conveyor line 110 and at least one processing station 140, and supplementary processing waiting station 155 is connected between one of the processing stations 140 and transfer channel 170. Transfer channel 170 is connected between transfer station 153 and supplementary processing waiting station 155. The magnetic drive structure includes a first magnetic drive structure 111, a transfer magnetic drive structure 114, and a supplementary processing magnetic drive structure 115. The first magnetic drive structure 111 and the supplementary processing magnetic drive structure 115 each correspond to eight fixtures 130, and the transfer magnetic drive structure 114 corresponds to a single fixture 130. Furthermore, the first magnetic drive structure 111 is located on logistics conveyor line 110, the transfer magnetic drive structure 114 is located at transfer station 153, and the supplementary processing magnetic drive structure 115 is located at supplementary processing waiting station 155.

[0069] In the above description, the battery conveying system 10 is a highly efficient and flexible automated production line configuration for the processing and transfer of batteries 160. Through the combined use of various magnetic drive structures and fixtures 130, the automated conveying and processing of batteries 160 can be achieved, reducing the risk of damage to batteries 160 and thus improving production efficiency. At the same time, the setting of the transfer channel 170 and the transfer magnetic drive structure 114 can flexibly adjust the conveying path of batteries 160 to meet different processing requirements.

[0070] The logistics conveyor line 110 includes a plurality of first magnetic drive structures 111 arranged in sequence and at least one transfer magnetic drive structure 114 located at the transfer station 153, which can form a continuous and stable conveying path to help the magnetic drive structures transport the fixture 130 and the battery 160 on the fixture 130, reducing the risk of electrolyte spillage or splashing from the battery 160 during transportation. The processing conveyor line 120 connects the logistics conveyor line 110 and at least one processing station 140 to transport the battery 160 to be processed on the logistics conveyor line 110 to the processing station 140, which can reduce the overall footprint of the battery conveying system 10 and improve production efficiency. The replenishment waiting station 155 is connected to one of the processing stations 140 and is equipped with a replenishment magnetic drive structure 115, which can simplify the electrolyte replenishment process for the battery 160 and reduce the transportation distance of the battery 160. The transfer channel 170 connects the transfer station 153 and the supplementary processing waiting station 155, and the transfer magnetic drive structure 114 is movably mounted on the transfer channel 170, which can reduce the safety risks in the transfer process of the battery 160. The fixture 130 includes a magnetic component 131 and a support component 132 for carrying the battery 160. The first magnetic drive structure 111, the transfer magnetic drive structure 114, and the supplementary processing magnetic drive structure 115 are used to drive the fixture 130 through the magnetic component 131, which can improve the transportation method of the battery 160 and thus improve the stability of the battery 160 transportation.

[0071] According to some embodiments of this application, referring to Figures 1 and 2, the first magnetic drive structure 111 and the finishing magnetic drive structure 115 are both used to drive multiple fixtures 130, and the transfer magnetic drive structure 114 is used to drive a single fixture 130.

[0072] The magnetic drive structure includes a first magnetic drive structure 111, a transfer magnetic drive structure 114, and a supplementary processing magnetic drive structure 115. The first magnetic drive structure 111 is located on the logistics conveyor line 110, the transfer magnetic drive structure 114 is located at the transfer station 153, and the supplementary processing magnetic drive structure 115 is located at the supplementary processing waiting station 155. The first magnetic drive structure 111 and the supplementary processing magnetic drive structure 115 are both used to drive multiple fixtures 130, and the transfer magnetic drive structure 114 is used to drive a single fixture 130.

[0073] For example, the first magnetic drive structure 111 and the supplementary machining magnetic drive structure 115 correspond to eight fixtures 130 respectively, and the transfer magnetic drive structure 114 corresponds to a single fixture 130.

[0074] In the above description, both the first magnetic drive structure 111 and the replenishment magnetic drive structure 115 are used to drive multiple fixtures 130. The first magnetic drive structure 111 drives the multiple fixtures 130 to move on the material conveyor line 110, moving the multiple fixtures 130 to the processing station 140 or the transfer station 153. The replenishment magnetic drive structure 115 drives the multiple fixtures 130 from the replenishment waiting station 155 to the processing station 140. Unlike the first magnetic drive structure 111 and the replenishment magnetic drive structure 115, the transfer magnetic drive structure 114 is used to drive a single fixture 130, moving the single fixture 130 corresponding to the battery 160 to be replenished from the transfer station 153 to the replenishment waiting station 155. In addition, the transfer magnetic drive structure 114 drives the single fixture 130 to move on the transfer channel 170, which is configured to allow only a single fixture 130 to pass through.

[0075] Multiple fixtures 130 are driven by the first magnetic drive structure 111 and the supplementary processing magnetic drive structure 115, and a single fixture 130 is driven by the transfer magnetic drive structure 114. This allows for efficient processing of a large number of batteries 160 during liquid injection and replenishment at the processing station 140, thereby improving the production efficiency of the processing station 140. It also allows for precise control of the movement of a single fixture 130 at the transfer station 153.

[0076] According to some embodiments of this application, referring to Figures 1 and 2, the processing conveyor line 120 and the transfer channel 170 are both arranged to intersect with the logistics conveyor line 110, the processing conveyor line 120 and the transfer channel 170 are arranged parallel and spaced apart, and the supplementary processing waiting station 155 is arranged parallel and spaced apart from the logistics conveyor line 110.

[0077] The logistics conveyor line 110 is responsible for transporting the battery 160 from the loading station to multiple processing stations 140 and transfer stations 153. Multiple first magnetic drive structures 111 are sequentially arranged on the logistics conveyor line 110 to drive multiple fixtures 130 to move along the conveyor line. The processing conveyor line 120 is intersected with the logistics conveyor line 110, connecting the logistics conveyor line 110 to at least one processing station 140. This intersecting arrangement allows the battery 160 to be transferred from the logistics conveyor line 110 to the processing conveyor line 120, and then enter the processing station 140 for processing. After processing, the battery 160 can return to the logistics conveyor line 110 via the processing conveyor line 120, and then reach the transfer station 153 or enter a subsequent processing step via the logistics conveyor line 110.

[0078] The transfer channel 170 is a dedicated channel connecting the transfer station 153 and the supplementary processing waiting station 155. It also intersects with the logistics conveyor line 110, but the transfer channel 170 is parallel and spaced apart from the processing conveyor line 120 to reduce interference and improve the stability of the battery 160 transfer process. The transfer magnetic drive structure 114 is movably mounted on the transfer channel 170 and is used to drive a single fixture 130 to move along the transfer channel 170.

[0079] The supplementary processing waiting station 155 is connected between the transfer channel 170 and one of the processing stations 140, and is set parallel to and spaced apart from the logistics conveyor line 110. This can reduce the interference of the battery 160 on the logistics conveyor line 110 during the supplementary processing waiting process. A supplementary processing magnetic drive structure 115 is also set on the supplementary processing waiting station 155 to drive multiple fixtures 130, so that the battery 160 can move between the supplementary processing waiting station 155 and the processing station 140.

[0080] In the above description, the first magnetic drive structure 111 is located on the logistics conveyor line 110, the transfer magnetic drive structure 114 is located at the transfer station 153, and the supplementary processing magnetic drive structure 115 is located at the supplementary processing waiting station 155. The transfer station 153 is located at the intersection of the logistics conveyor line 110 and the transfer channel 170, and is a key position for transferring the battery 160 from the logistics conveyor line 110 to the transfer channel 170. At the transfer station 153, the fixture 130 and the battery 160 on it are accurately transferred to the transfer channel 170 via the transfer magnetic drive structure 114. The supplementary processing waiting station 155 is located at the intersection of the transfer channel 170 and the processing station 140. At the supplementary processing waiting station 155, the fixture 130 and the battery 160 on it are transferred to the processing station 140 via the supplementary processing magnetic drive structure 115.

[0081] For example, the efficient conveying and transfer of batteries 160 can be achieved through the cross-arranged processing conveyor lines 120 and transfer channels 170, as well as the parallel and spaced supplementary processing waiting stations 155. The cross-layout and different magnetic drive structures allow batteries 160 to be flexibly transferred between different conveyor lines and stations. Through a reasonable layout and efficient automated processing flow, production efficiency can be improved, production costs reduced, and the quality and stability of batteries 160 enhanced.

[0082] According to some embodiments of this application, referring to Figures 1 and 2, the logistics conveyor line 110 includes: a bridging position and a post-checking station 154. The processing conveyor line 120 and the logistics conveyor line 110 are intersected at the bridging position. The post-checking station 154 is located downstream of all the bridging positions, and the transfer station 153 is located downstream of the post-checking station 154.

[0083] The logistics conveyor line 110 is responsible for transporting the battery 160 from the starting point to various processing stations 140, transfer stations 153, and post-processing stations. The processing conveyor line 120 is responsible for transporting the battery 160 from the logistics conveyor line 110 to the processing station 140. The bridging position is the intersection of the logistics conveyor line 110 and the processing conveyor line 120. The first magnetic drive structure 111 is located at the bridging position, and the third magnetic drive structure is located at the processing station 140. It can move between the processing station 140 and the bridging position via the processing conveyor line 120. At the bridging position, the battery 160 can be transferred from the logistics conveyor line 110 to the processing conveyor line 120 via the third magnetic drive structure and enter the processing station 140 for processing. The design of the bridging position can help the battery 160 be transferred smoothly and accurately from one conveyor line to another.

[0084] The post-verification station 154 is located downstream of the bridging position. After the battery 160 passes through the bridging position and completes processing, it returns to the logistics conveyor line 110 and arrives at the post-verification station 154. The post-verification station 154 is used for post-processing work such as quality inspection of the battery 160 to ensure that the battery 160 meets quality standards. The transfer station 153 is located downstream of the post-verification station 154. After the battery 160 completes processing, it arrives at the post-verification station 154. At the post-verification station 154, the battery 160 can be checked for the need for electrolyte replenishment. Then, the battery 160 arrives at the transfer station 153. Batteries 160 requiring electrolyte replenishment are transferred to the transfer channel 170 and enter the replenishment waiting station 155. Other qualified batteries 160 continue to the next process.

[0085] In the above description, the processing conveyor line 120 and the logistics conveyor line 110 are arranged at a bridging position to connect the logistics conveyor line 110 with at least one processing station 140. This cross arrangement allows the battery 160 to be easily transferred from the logistics conveyor line 110 to the processing conveyor line 120, and then enter the processing station 140 for processing. After processing, the battery 160 can return to the logistics conveyor line 110 via the processing conveyor line 120 to continue to the next process. In addition, the transfer channel 170 connects the transfer station 153 and the supplementary processing waiting station 155, forming a bridge that allows the fixture 130 and the battery 160 on it to move between these two positions.

[0086] Through a reasonable cross-layout and efficient automated processing, the battery 160 can be transferred between different conveyor lines and workstations, significantly improving production efficiency, reducing production costs, and helping to improve the quality and stability of the battery 160.

[0087] According to some embodiments of this application, as shown in Figures 1 and 2, there are multiple processing conveyor lines 120, which are spaced apart along the length of the logistics conveyor line 110. The supplementary processing waiting station 155 is connected to the processing station 140 closest to the transfer station 153.

[0088] Multiple processing conveyor lines 120 are arranged at intervals along the length of the logistics conveyor line 110. Each processing conveyor line 120 connects to two processing stations 140. The multiple processing conveyor lines 120 and the logistics conveyor line 110 form multiple bridging positions. Each bridging position corresponds to a first magnetic drive structure 111. Two adjacent first magnetic drive structures 111 are connected through a second magnetic drive structure. Each processing station 140 corresponds to a third magnetic drive structure. The battery 160 can be transferred from the logistics conveyor line 110 to any of the processing conveyor lines 120 at the bridging positions via the third magnetic drive structure, and then enter the corresponding processing station 140 for processing.

[0089] The supplementary processing waiting station 155 is connected to the processing station 140 closest to the transfer station 153. After the battery 160 has completed the liquid injection, the unqualified battery 160 needs further liquid replenishment. The battery 160 waiting for liquid replenishment is transferred to the supplementary processing waiting station 155. After eight batteries are collected in the supplementary processing waiting station 155, they are sent to the corresponding processing station 140 for processing.

[0090] In the above description, there are multiple processing conveyor lines 120, which are spaced apart along the length of the logistics conveyor line 110. A supplementary processing waiting station 155 is connected to a processing station 140 closest to the transfer station 153. This arrangement of multiple processing conveyor lines 120 spaced apart along the length of the logistics conveyor line 110 allows the system to process multiple batteries 160 simultaneously, thereby improving production efficiency. The design of the supplementary processing waiting station 155 facilitates the smooth flow of batteries 160 during supplementary processing, reducing congestion on the production line.

[0091] By setting up multiple processing conveyor lines 120 and supplementary processing waiting stations 155, the processing path of the battery 160 can be flexibly adjusted to meet supplementary processing needs. At the same time, through reasonable layout and efficient automated processing, production efficiency can be improved and production costs can be reduced.

[0092] According to some embodiments of this application, this application also provides a battery processing system, including a battery conveying system 10 and a processing equipment 20 of any of the above schemes, wherein the processing equipment 20 is used to process the battery 160 located at the processing station 140.

[0093] The battery conveying system 10 is mainly used to transport batteries 160 from the loading station to the processing station 140, and after processing, to the next stage. The battery conveying system 10 includes: a material conveyor line 110, a processing conveyor line 120, a supplementary processing waiting station 155, a transfer channel 170, and a fixture 130. Through the material conveyor line 110 and the processing conveyor line 120, the batteries 160 can be smoothly and quickly transported to the designated processing station 140. The battery conveying system 10 also employs automation technology to achieve high-precision positioning and transmission.

[0094] The processing equipment 20 is used to process the battery 160 located at the processing station 140, and the type and quantity of the processing equipment 20 depend on the specific processing requirements and the type of battery 160. For example, in the manufacturing process of electric vehicle batteries, the processing equipment 20 can be a charging and discharging testing equipment, a packaging equipment, or a quality inspection equipment, etc., used to perform charging, discharging testing, or packaging processes on the battery 160 located at the processing station 140.

[0095] When battery 160 is conveyed to processing station 140, processing equipment 20 automatically performs processing operations and, upon completion, transports battery 160 back to processing conveyor line 120 or transfers it to the next process. Through the close cooperation between processing equipment 20 and processing conveyor line 120, the continuity and efficiency of battery 160 processing can be improved, achieving a high degree of automation in battery 160 processing, thereby increasing production efficiency. Simultaneously, the layout of multiple processing conveyor lines 120 can handle multiple sets of batteries 160 at the same time, further improving production efficiency. Furthermore, the coordinated work of battery conveying system 10 and processing equipment 20 ensures the smooth operation of the entire battery processing system.

[0096] According to some embodiments of this application, referring to FIG4, the processing equipment 20 is a liquid injection device for injecting liquid into the battery 160 located at the processing station 140.

[0097] The battery processing system includes a battery conveying system 10 and a processing device 20. The battery conveying system 10 is mainly responsible for accurately conveying the battery 160 from the storage or pre-processing station to the processing station 140 of the liquid injection equipment, and conveying it to the next processing stage after liquid injection. The battery conveying system 10 has high positioning accuracy, which helps to accurately position the battery 160 at the liquid injection station, so that the liquid injection equipment can accurately inject liquid into the battery 160. The battery conveying system 10 can also achieve smooth and shock-free transmission, reducing damage to the battery 160 during transmission.

[0098] For example, the processing equipment 20 can be a liquid injection device, responsible for injecting an appropriate amount of electrolyte into the battery 160 located at the processing station 140. In addition to injecting electrolyte into the battery 160 located at the processing station 140, the processing equipment 20 can also be used to replenish electrolyte in the battery 160 with insufficient electrolyte.

[0099] In the above description, the electrolyte injection equipment has a high-precision electrolyte injection control system to ensure that each battery 160 receives the appropriate amount of electrolyte. The equipment also has a fast electrolyte injection speed, which can improve production efficiency and enhance the stability and accuracy of the electrolyte injection process.

[0100] The battery processing system can be operated efficiently through the coordinated work between the battery delivery system 10 and the liquid injection equipment.

[0101] According to some embodiments of this application, this application also provides a battery production line, including a battery processing system of any of the above solutions.

[0102] The battery production line is a complete manufacturing process line from raw materials to finished battery 160, covering multiple links such as battery 160 pretreatment, core processing, post-processing and quality inspection. Among them, the battery processing system is mainly responsible for the core processing of battery 160, such as liquid injection, packaging and welding.

[0103] For example, in a battery production line, the battery processing system includes a battery conveying system 10 and processing equipment 20, which, together with other auxiliary equipment and processes, complete the processing of battery 160. Processing equipment 20 can be an electrolyte injection device, responsible for injecting an appropriate amount of electrolyte into the battery 160 located at processing station 140. The battery conveying system 10 is responsible for conveying the battery 160 from the pretreatment station to the electrolyte injection station, and after electrolyte injection, conveying it to the next processing stage. The battery processing system may also include encapsulation equipment and welding equipment. The encapsulation equipment is used to encapsulate the battery 160 after electrolyte injection to improve the sealing and safety of the battery 160. The welding equipment is used for welding the internal connectors of the battery 160 to ensure reliable internal electrical connections.

[0104] In the above description, the process flow on the battery production line includes pretreatment, electrolyte injection, encapsulation, welding, and post-processing and quality inspection. Pretreatment involves cleaning and deburring the battery 160 to prepare for electrolyte injection. Electrolyte injection involves injecting electrolyte into the battery 160 to prepare for the chemical reaction. Encapsulation involves sealing the battery 160 after electrolyte injection to ensure its airtightness and safety. Welding involves welding the internal connectors of the battery 160 to ensure reliable electrical connections. Post-processing and quality inspection involve performing aging tests or performance tests on the encapsulated and welded battery 160 to ensure that its quality meets standards.

[0105] A battery production line is a complex system that integrates multiple processes and equipment. By achieving automated control of the battery production line, the production process can be optimized, and production efficiency and quality can be improved.

[0106] According to some embodiments of this application, as shown in Figures 1-3, this application also provides a battery processing method using a battery processing system, comprising: verifying the processing results of processed batteries 160 at a post-verification station 154 of a logistics conveyor line 110, and identifying target batteries 160 that do not meet the target conditions; if it is determined that the target batteries 160 are to be transported to a transfer station 153, controlling the transfer magnetic drive structure 114 to move along the transfer channel 170 to a supplementary processing waiting station 155; controlling the supplementary processing magnetic drive structure 115 to transport the batteries 160 located at the supplementary processing waiting station 155 to the processing station 140; and controlling the processing equipment 20 to process the batteries 160 located at the processing station 140.

[0107] The battery processing method mainly utilizes key components such as the logistics conveyor line 110, the post-verification station 154, the transfer magnetic drive structure 114, the supplementary processing waiting station 155, the supplementary processing magnetic drive structure 115, and the processing equipment 20 in the battery processing system to achieve automated control and optimization of the battery 160 processing process.

[0108] For example, battery 160 is transported on logistics conveyor line 110, passing through each processing station 140 in sequence. At the post-verification station 154 of logistics conveyor line 110, the processed battery 160 is verified, and target batteries 160 that do not meet the target conditions are identified through verification. Once the target battery 160 is identified, the transfer magnetic drive structure 114 is automatically controlled to move the target battery 160 along the transfer channel 170 to the supplementary processing waiting station 155. The transfer magnetic drive structure 114 uses magnetic drive technology to achieve a fast and smooth transfer process. Transfer station 153 is the connection point between the transfer magnetic drive structure 114 and the supplementary processing waiting station 155, facilitating the transfer of target battery 160 to the supplementary processing waiting station 155. Battery 160 located at the supplementary processing waiting station 155 waits to be transferred to processing station 140, and then the supplementary processing magnetic drive structure 115 is controlled to transport battery 160 located at the supplementary processing waiting station 155 to processing station 140. At processing station 140, processing equipment 20 reprocesses battery 160 to correct errors or problems that occurred during previous processing, ensuring that the quality of battery 160 meets the target conditions.

[0109] In the above description, by introducing automated components such as the logistics conveyor line 110, the transfer magnetic drive structure 114, and the processing equipment 20, the automated control and optimization of the battery processing and transfer process can be realized, thereby improving the efficiency and quality of battery 160 processing.

[0110] According to some embodiments of this application, as shown in Figures 1 and 2, after controlling the transfer magnetic drive structure 114 to move along the transfer channel 170 to the supplementary processing waiting station 155, the method further includes: controlling the transfer magnetic drive structure 114 to move along the transfer channel 170 to the transfer station 153 so that other processed batteries 160 can pass through.

[0111] After the processed battery 160 arrives at the transfer station 153, the target battery 160 moves along the transfer channel 170 to the supplementary processing waiting station 155 via the transfer magnetic drive structure 114. Other processed batteries 160 wait at the transfer station 153. After the target battery 160 moves to the supplementary processing waiting station 155, the transfer magnetic drive structure 114 is controlled to move along the transfer channel 170 to the transfer station 153. Other processed batteries 160 enter the next process after passing through the transfer station 153.

[0112] In the above description, the transfer magnetic drive structure 114 is responsible for transferring the target battery 160 to the supplementary processing waiting station 155 on the transfer channel 170, and at the same time, it is responsible for bridging the transfer station 153 on the logistics conveyor line 110 so that other processed batteries 160 other than the target battery 160 can pass through.

[0113] In terms of motion control of the transfer magnetic drive structure 114, this method can achieve a more flexible and efficient battery 160 transfer process. By optimizing the transfer process, the transfer magnetic drive structure 114 can quickly return to the transfer station 153 after completing a transfer task, ready to perform bridging or the next transfer, thereby improving the overall efficiency of battery 160 processing.

[0114] According to some embodiments of this application, when the processing equipment 20 is used to process multiple batteries 160, controlling the supplementary processing magnetic drive structure 115 to transport the batteries 160 located at the supplementary processing waiting station 155 to the processing station 140 includes: when it is determined that the number of batteries 160 located at the supplementary processing waiting station 155 is equal to the single processing quantity of the processing equipment 20, controlling the supplementary processing magnetic drive structure 115 to transport the batteries 160 located at the supplementary processing waiting station 155 to the processing station 140.

[0115] Batteries 160 are transported on the logistics conveyor line 110, passing through each processing station 140 in sequence. At the post-verification station 154 of the logistics conveyor line 110, the processed batteries 160 are verified. Through verification, target batteries 160 that do not meet the target conditions are identified and transferred to the reprocessing waiting station 155. The transfer magnetic drive structure 114 moves along the transfer channel 170 to the reprocessing waiting station 155 and transfers the target batteries 160 to this station. After the transfer is completed, the transfer magnetic drive structure 114 returns to the transfer station 153 to allow other processed batteries 160 to pass through. Batteries 160 located at the reprocessing waiting station 155 wait to be transferred to the processing station 140. The system monitors the number of batteries 160 located at the reprocessing waiting station 155 in real time.

[0116] In the above description, a group of processed batteries 160 arrives at the post-verification station 154, where one or more target batteries 160 are transferred. Other processed batteries 160 continue to move to the next process along the logistics conveyor line 110. The next group of processed batteries 160 repeats the above battery 160 processing process. After multiple repetitions, the number of target batteries 160 located at the supplementary processing waiting station 155 is equal to the single processing capacity of the processing equipment 20. Then, the supplementary processing magnetic drive structure 115 transports the multiple target batteries 160 located at the supplementary processing waiting station 155 to the processing station 140. At the processing station 140, the processing equipment 20 processes the batteries 160 transferred from the supplementary processing waiting station 155 again. After processing, the batteries 160 continue to be transferred to the post-verification station 154 for quality inspection via the logistics conveyor line 110.

[0117] This method, combined with the single-processing capacity of the processing equipment 20, can achieve a more refined battery 160 transfer and processing flow. By optimizing the transfer and processing flow, waiting time and resource waste can be reduced, and the overall efficiency of battery 160 processing can be improved.

[0118] According to some embodiments of this application, when the number of batteries 160 at the supplementary processing waiting station 155 is less than the processing capacity of the processing equipment 20 in a single operation, the processing equipment 20 corresponding to the processing station 140 connected to the supplementary processing waiting station 155 is used to process the batteries 160 transported by the processing conveyor line 120.

[0119] When the number of target batteries 160 at the supplementary processing waiting station 155 is the same as the single processing capacity of the processing equipment 20, the processing equipment 20 corresponding to the processing station 140 connected to the supplementary processing waiting station 155 processes the target batteries 160 transported from the supplementary processing waiting station 155. When the number of target batteries 160 at the supplementary processing waiting station 155 is less than the single processing capacity of the processing equipment 20, the target batteries 160 wait at the supplementary processing waiting station 155, and the processing equipment 20 corresponding to the processing station 140 connected to the supplementary processing waiting station 155 processes the unprocessed batteries 160 transported through the processing conveyor line 120.

[0120] In the above description, when the number of batteries 160 at the waiting station 155 is insufficient, this method can flexibly adjust the processing objects of the processing equipment 20, reduce waiting time and resource waste, and improve the continuity and efficiency of the production line.

[0121] Specifically, according to some embodiments of this application, as shown in Figures 1-6, this application provides a battery conveying system 10, a battery processing system, a battery production line, and a battery processing method.

The supplementary processing waiting station 155 is set parallel to and spaced apart from the logistics conveyor line 110, and the supplementary processing waiting station 155 is connected to the processing station 140 closest to the transfer station 153.

[0127] At the post-verification station 154 of the logistics conveyor line 110, the processing results of the processed batteries 160 are verified, and target batteries 160 that do not meet the target conditions are identified. Then, with the target batteries 160 transported to the transfer station 153, the transfer magnetic drive structure 114 is controlled to move along the transfer channel 170 to the supplementary processing waiting station 155. The transfer magnetic drive structure 114 continues to move along the transfer channel 170 to the transfer station 153 to allow other processed batteries 160 to pass through. At the same time, the supplementary processing magnetic drive structure 115 is controlled to transport the batteries 160 located at the supplementary processing waiting station 155 to the processing station 140, and the processing equipment 20 is controlled to process the batteries 160 located at the processing station 140.

[0128] If the number of batteries 160 located at the supplementary processing waiting station 155 is equal to the single processing capacity of the processing equipment 20, the supplementary processing magnetic drive structure 115 is controlled to transport the batteries 160 located at the supplementary processing waiting station 155 to the processing station 140. If the number of batteries 160 at the supplementary processing waiting station 155 is less than the single processing capacity of the processing equipment 20, the processing equipment 20 corresponding to the processing station 140 connected to the supplementary processing waiting station 155 is used to process the batteries 160 transported through the processing conveyor line 120.
