[0040] In recent years, new energy vehicles have developed by leaps and bounds. In the field of electric vehicles, power batteries, as the power source of electric vehicles, play an irreplaceable and important role. The battery pack consists of a box and multiple battery cells contained in the box. Among them, batteries, as core components of new energy vehicles, have high requirements in terms of safety and cycle life.

[0041] In the production process of batteries, there is a situation where the amount of liquid injected is insufficient in the liquid injection process, and batteries with insufficient liquid injection need to be automatically replenished. The inventors found that in the related art, batteries with insufficient liquid injection are usually transferred from the temporary storage station to the entrance of the liquid injection station.

Figure 5 It is a structural schematic diagram of a clamp 130 of a battery conveying system 10 according to an embodiment of the present application. Figure 6 for Figure 5The present application provides a battery conveying system 10, which includes: a logistics conveying line 110, a processing conveying line 120, a supplementary processing waiting station 155, a transfer channel 170 and a clamp 130, so as to solve the problem that the battery 160 refilling process is complicated and there are safety risks in the battery 160 transfer process.

[0045] The logistics conveying 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 a transfer station 153. The plurality of first magnetic drive structures 111 on the logistics conveying line 110 are arranged in sequence to form a continuous conveying path. The magnetic drive structure drives the clamp 130 by magnetic force to move the clamp 130 along the logistics conveying line 110. At the same time, a transfer station 153 is set on the logistics conveying line 110 to transfer the clamp 130 and the battery 160 on the clamp 130 from one conveying path to another path or device.

[0046] At the same time, a transfer magnetic drive structure 114 is provided on the transfer station 153, and the transfer magnetic drive structure 114 is mainly used to drive a specific clamp 130 on the transfer channel 170. The processing conveyor line 120 connects the logistics conveyor line 110 and at least one processing station 140 respectively. 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 supplementary processing 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. The supplementary processing waiting station 155 is provided with a supplementary processing magnetic drive structure 115, which is used to drive the clamp 130 to move the battery 160 between the supplementary processing waiting station 155 and the processing station 140.

[0047] The transfer channel 170 connects the transfer station 153 and the supplementary processing waiting station 155 to form a passage, so that the fixture 130 and the battery 160 on the fixture 130 can move quickly between these two positions. At the same time, the transfer magnetic drive structure 114 is movably installed on the transfer channel 170, and the transfer magnetic drive structure 114 can move along the transfer channel 170 to adapt to different transfer needs.

[0048] like Figure 3-Figure 5 As shown, the clamp 130 includes a magnetic member 131 and a carrier 132 for carrying a battery 160, wherein the magnetic member 131 is used to interact with the magnetic drive structure so that the clamp 130 can be driven to move, and the carrier 132 is used to carry the battery 160 so that the battery 160 remains stable during transportation and processing, wherein 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 clamp 130 through the magnetic member 131.

[0049] Exemplarily, the processing conveyor line 120 is connected between the logistics conveyor line 110 and at least one processing station 140, the supplementary processing waiting station 155 is connected between one of the processing stations 140 and the transfer channel 170, and the transfer channel 170 is connected between the transfer station 153 and the supplementary processing waiting station 155.

In addition, 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.

[0050] In the above description, the battery conveying system 10 is an efficient and flexible automated production line configuration, which is used for the processing and transportation of batteries 160. Through the coordinated use of various magnetic drive structures and fixtures 130, the automated transportation and processing of the batteries 160 can be realized, reducing the risk of damage to the batteries 160, thereby 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 the battery 160 to meet different processing requirements.

[0051] 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, and help the magnetic drive structure to transport the fixture 130 and the battery 160 on the fixture 130, thereby reducing the risk of electrolyte spilling or splashing in the battery 160 during transportation. The processing conveyor line 120 is connected between the logistics conveyor line 110 and at least one processing station 140, and is used 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 supplementary processing waiting station 155 is connected to one of the processing stations 140, and is provided with a supplementary processing magnetic drive structure 115, which can simplify the battery 160 rehydration process and reduce the transportation distance of the battery 160. The transport channel 170 is connected between the transport station 153 and the supplementary processing waiting station 155, and the transport magnetic drive structure 114 is movably installed in the transport channel 170, which can reduce the safety risks in the transport process of the battery 160. The clamp 130 includes a magnetic member 131 and a carrier 132 for carrying the battery 160. The first magnetic drive structure 111, the transport magnetic drive structure 114 and the supplementary processing magnetic drive structure 115 are used to drive the clamp 130 through the magnetic member 131, which can improve the transportation method of the battery 160, thereby improving the stability of the transportation of the battery 160.

[0052] According to some embodiments of the present application, referring to Figure 1 and Figure 2The first magnetic drive structure 111 and the supplementary magnetic drive structure 115 are both used to drive multiple clamps 130 , and the transfer magnetic drive structure 114 is used to drive a single clamp 130 .

[0053] 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 conveying 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 clamps 130, and the transfer magnetic drive structure 114 is used to drive a single clamp 130.

[0054] Exemplarily, the first magnetic drive structure 111 and the supplementary magnetic drive structure 115 correspond to eight fixtures 130 respectively, and the transfer magnetic drive structure 114 corresponds to a single fixture 130 .

[0055] In the above description, the first magnetic drive structure 111 and the supplementary processing magnetic drive structure 115 are both used to drive multiple clamps 130, wherein the first magnetic drive structure 111 drives multiple clamps 130 to move on the logistics conveying line 110, and moves multiple clamps 130 to the processing station 140 or the transfer station 153, and the supplementary processing magnetic drive structure 115 drives multiple clamps 130 to move from the supplementary processing waiting station 155 to the processing station 140. Different from the first magnetic drive structure 111 and the supplementary processing magnetic drive structure 115, the transfer magnetic drive structure 114 is used to drive a single clamp 130, and moves a single clamp 130 corresponding to the battery 160 to be replenished from the transfer station 153 to the supplementary processing waiting station 155. In addition, the transfer magnetic drive structure 114 drives a single clamp 130 to move on the transfer channel 170, and the transfer channel 170 is set to allow only a single clamp 130 to pass through.

[0056] By driving multiple clamps 130 through the first magnetic drive structure 111 and the supplementary processing magnetic drive structure 115, and driving a single clamp 130 through the transfer magnetic drive structure 114, a large number of batteries 160 can be efficiently processed when the batteries 160 are injected and replenished at the processing station 140, thereby improving the production efficiency of the processing station 140, and the movement of a single clamp 130 can also be accurately controlled at the transfer station 153.

[0057] According to some embodiments of the present application, referring to Figure 1 and Figure 2 The processing conveyor line 120 and the transfer channel 170 are both arranged to cross the logistics conveyor line 110, the processing conveyor line 120 and the transfer channel 170 are arranged in parallel and spaced apart from each other, and the supplementary processing waiting station 155 is arranged in parallel and spaced apart from the logistics conveyor line 110.

[0058] The logistics conveyor line 110 is responsible for conveying the battery 160 from the loading station to multiple processing stations 140 and the transfer station 153. Multiple first magnetic drive structures 111 are arranged in sequence on the logistics conveyor line 110 to drive multiple fixtures 130 to move along the conveyor line. The processing conveyor line 120 is arranged crosswise with the logistics conveyor line 110, connecting the logistics conveyor line 110 with at least one processing station 140. This cross layout 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 the processing is completed, the battery 160 can return to the logistics conveyor line 110 through the processing conveyor line 120, and then reach the transfer station 153 or enter the subsequent processing process through the logistics conveyor line 110.

[0059] The transfer channel 170 is a dedicated channel connecting the transfer station 153 and the supplementary processing waiting station 155. It is also arranged to cross the logistics conveyor line 110, but the transfer channel 170 is arranged in parallel and spaced apart from the processing conveyor line 120, which can reduce interference and improve the stability of the transfer process of the battery 160. The transfer magnetic drive structure 114 is movably installed on the transfer channel 170 to drive a single fixture 130 to move on the transfer channel 170.

[0060] The supplementary processing waiting station 155 is connected between the transfer channel 170 and one of the processing stations 140, and is arranged in parallel and spaced apart from the logistics conveying line 110, which can reduce the interference of the battery 160 on the logistics conveying 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, which is used to drive multiple clamps 130 to move the battery 160 between the supplementary processing waiting station 155 and the processing station 140.

[0061] In the above description, the first magnetic drive structure 111 is located on the logistics conveying 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 conveying line 110 and the transfer channel 170. It is a key position for the battery 160 to be transferred from the logistics conveying line 110 to the transfer channel 170. At the transfer station 153, the fixture 130 and the battery 160 thereon are accurately transferred to the transfer channel 170 through 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 thereon are transferred to the processing station 140 through the supplementary processing magnetic drive structure 115.

[0062] For example, by cross-arranged processing conveyor lines 120 and transfer channels 170, and parallel spaced supplementary processing waiting stations 155, efficient battery 160 transportation and transportation can be achieved, while the cross-layout and different magnetic drive structures allow the battery 160 to be flexibly transferred between different conveyor lines and stations. Through reasonable layout and efficient automated processing flow, production efficiency can be improved, production costs can be reduced, and the quality and stability of the battery 160 can be improved.

[0063] According to some embodiments of the present application, referring to Figure 1 and Figure 2 The logistics conveyor line 110 includes: a bridging position and a post-verification station 154. The processing conveyor line 120 and the logistics conveyor line 110 are cross-arranged at the bridging position. The post-verification station 154 is located downstream of all the bridging positions, and the transfer station 153 is located downstream of the post-verification station 154.

[0064] The logistics conveyor line 110 is responsible for conveying the battery 160 from the starting point to each processing station 140, the transfer station 153 and the post-processing station, and the processing conveyor line 120 is responsible for conveying 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 be moved between the processing station 140 and the bridging position through the processing conveyor line 120. The battery 160 can be transferred from the logistics conveyor line 110 to the processing conveyor line 120 at the bridging position through the third magnetic drive structure, and enter the processing station 140 for processing. The design of the bridging position can help the battery 160 to be smoothly and accurately transferred from one conveyor line to another.

[0065] The post-check station 154 is located downstream of the bridge position, that is, the battery 160 passes through the bridge position and returns to the logistics conveyor line 110 after processing. The post-check station 154 is used to perform post-processing work such as quality inspection on the battery 160 to ensure that the battery 160 meets the quality standards. The transfer station 153 is located downstream of the post-check station 154, that is, after the battery 160 is processed, it arrives at the post-check station 154. The battery 160 can be checked at the post-check station 154 to see if it needs to be replenished. Then the battery 160 arrives at the transfer station 153, and the battery 160 to be replenished is transferred to the transfer channel 170 and enters the replenishment waiting station 155. Other qualified batteries 160 continue to the next process.

[0066] In the above description, the processing conveyor line 120 and the logistics conveyor line 110 are cross-arranged at the bridge position to connect the logistics conveyor line 110 and 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, thereby entering the processing station 140 for processing. After the processing is completed, the battery 160 can return to the logistics conveyor line 110 through the processing conveyor line 120 to continue the next process. In addition, the transfer channel 170 connects the transfer station 153 and the supplementary processing waiting station 155 to form a bridge, so that the fixture 130 and the battery 160 thereon can move between these two positions.

[0067] Through reasonable cross-layout and efficient automated processing flow, the battery 160 can be transferred between different conveyor lines and workstations, which significantly improves production efficiency, reduces production costs, and helps to improve the quality and stability of the battery 160.

[0068] According to some embodiments of this application, see Figure 1 and Figure 2 As shown, there are multiple processing conveyor lines 120, and the multiple processing conveyor lines 120 are arranged at intervals along the length direction of the logistics conveyor line 110, and the supplementary processing waiting station 155 is connected to a processing station 140 closest to the transfer station 153.

[0069] Multiple processing conveyor lines 120 are arranged at intervals along the length direction of the logistics conveyor line 110, each processing conveyor line 120 is connected to two processing stations 140, and multiple processing conveyor lines 120 and the logistics conveyor line 110 form multiple bridge positions, each bridge position corresponds to a first magnetic drive structure 111, and two adjacent first magnetic drive structures 111 are connected through the second magnetic drive structure, and 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 processing conveyor line 120 at the bridge position through the third magnetic drive structure, and enter the corresponding processing station 140 for processing.

[0070] The supplementary processing waiting station 155 is connected to a processing station 140 closest to the transfer station 153. After the battery 160 is filled with liquid, the unqualified battery 160 needs further liquid replenishment treatment. The battery 160 to be replenished is transferred to the supplementary processing waiting station 155. After there are eight supplementary processing waiting stations 155, they enter the corresponding processing station 140 for processing together.

[0071] In the above description, there are multiple processing conveyor lines 120, and the multiple processing conveyor lines 120 are arranged at intervals along the length direction of the logistics conveyor line 110, and the supplementary processing waiting station 155 is connected to a processing station 140 closest to the transfer station 153. The layout of multiple processing conveyor lines 120 arranged at intervals along the length direction of the logistics conveyor line 110 enables the system to process multiple batteries 160 at the same time, thereby improving production efficiency. The design of the supplementary processing waiting station 155 helps the smooth flow of batteries 160 during the supplementary processing process and reduces congestion on the production line.

[0072] 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 the supplementary processing needs. At the same time, through reasonable layout and efficient automated processing procedures, production efficiency can be improved and production costs can be reduced.

[0073] According to some embodiments of the present application, the present application further provides a battery processing system, comprising a battery conveying system 10 and a processing device 20 according to any of the above schemes, wherein the processing device 20 is used to process a battery 160 located at a processing station 140 .

[0074] The battery conveying system 10 is mainly used to convey the battery 160 from the loading station to the processing station 140, and convey it to the next stage after the processing is completed. The battery conveying system 10 includes: a logistics conveying line 110, a processing conveying line 120, a supplementary processing waiting station 155, a transfer channel 170 and a fixture 130. Through the transmission devices such as the logistics conveying line 110 and the processing conveying line 120, the battery 160 can be smoothly and quickly conveyed to the designated processing station 140. The battery conveying system 10 also uses automation technology to achieve high-precision positioning and transmission.

[0075] 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 the battery 160. For example, in the electric vehicle battery manufacturing process, the processing equipment 20 can be a charging and discharging test equipment, a packaging equipment or a quality inspection equipment, etc., which is used to perform charging, discharging testing or packaging on the battery 160 located at the processing station 140.

[0076] When the battery 160 is transported to the processing station 140, the processing equipment 20 automatically performs the processing operation, and after completion, transports the battery 160 back to the processing conveyor line 120 or transfers it to the next process. Through the close cooperation between the processing equipment 20 and the processing conveyor line 120, the continuity and efficiency of the battery 160 during the processing process can be improved, and the high degree of automation of the battery 160 processing can be achieved, thereby improving production efficiency. At the same time, the layout of multiple processing conveyor lines 120 can process multiple groups of batteries 160 at the same time, thereby further improving production efficiency. In addition, through the coordinated work of the battery conveying system 10 and the processing equipment 20, the entire processing process of the battery processing system can be carried out smoothly.

[0077] According to some embodiments of the present application, referring to Figure 4 The processing equipment 20 is a liquid injection equipment, which is used to inject liquid into the battery 160 located at the processing station 140.

[0078] 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 injection equipment, and conveying it to the next processing stage after the injection is completed. The battery conveying system 10 has a high positioning accuracy, which helps to accurately position the battery 160 at the injection station so that the injection equipment can accurately inject the liquid into the battery 160. The battery conveying system 10 can also achieve smooth and impact-free transmission, reducing damage to the battery 160 during the transmission process.

[0079] Exemplarily, the processing equipment 20 may 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 being used to inject electrolyte into the battery 160 located at the processing station 140, the processing equipment 20 may also be used to replenish electrolyte for the battery 160 with insufficient electrolyte injection.

[0080] In the above description, the injection equipment has a high-precision injection control system so that each battery 160 can obtain an appropriate amount of electrolyte. The injection equipment also has a faster injection speed, which can improve production efficiency while improving the stability and accuracy of the injection process.

[0081] Through the coordinated work between the battery conveying system 10 and the liquid injection equipment, efficient operation of the battery processing system can be achieved.

[0082] According to some embodiments of the present application, the present application also provides a battery production line, comprising a battery processing system of any of the above schemes.

[0083] The battery production line is a complete manufacturing process line from raw materials to finished battery 160, covering multiple links such as pre-processing, core processing, post-processing and quality inspection of battery 160. Among them, the battery processing system is mainly responsible for the core processing of battery 160, such as liquid filling, packaging and welding.

[0084] Exemplarily, in a battery production line, the battery processing system includes a battery conveying system 10 and processing equipment 20, and cooperates with other auxiliary equipment and processes to complete the processing of the battery 160. The processing equipment 20 can be a liquid injection device, which is responsible for injecting an appropriate amount of electrolyte into the battery 160 located at the processing station 140. The battery conveying system 10 is responsible for transporting the battery 160 from the pretreatment station to the liquid injection station, and transporting it to the next processing stage after the liquid injection is completed. The battery processing system may also include packaging equipment and welding equipment. The packaging equipment is used to package the battery 160 after the liquid injection is completed 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 that the electrical connection inside the battery 160 is reliable.

[0085] In the above description, the process flow on the battery production line includes pretreatment, liquid injection, packaging, welding, post-processing and quality inspection. Pretreatment is to clean and deburr the battery 160 in preparation for liquid injection. Liquid injection is to inject electrolyte into the battery 160 to complete the chemical reaction preparation of the battery 160. Packaging is to package the battery 160 after liquid injection to ensure the sealing and safety of the battery 160. Welding is to weld the internal connectors of the battery 160 to ensure the reliable electrical connection inside the battery 160. Post-processing and quality inspection are to perform aging tests or performance tests on the battery 160 after packaging and welding to ensure that the quality of the battery 160 meets the standards.

[0086] The battery production line is a complex system that integrates multiple processes and equipment. By realizing automated control of the battery production line, the production process can be optimized and production efficiency and quality can be improved.

[0087] According to some embodiments of the present application, Figure 1-Figure 3 As shown, the present application also provides a battery processing method using a battery processing system, including: checking the processing results of the processed battery 160 at the post-check station 154 of the logistics conveying line 110, and determining the target battery 160 that does not meet the target conditions; when it is determined that the target battery 160 is transported to the transfer station 153, controlling the transfer magnetic drive structure 114 to move along the transfer channel 170 to the supplementary processing waiting station 155; controlling the supplementary processing magnetic drive structure 115 to transport the battery 160 located at the supplementary processing waiting station 155 to the processing station 140; and controlling the processing equipment 20 to process the battery 160 located at the processing station 140.

[0088] The battery processing method mainly realizes automatic control and optimization of the battery 160 processing process through key components such as the logistics conveying 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.

[0089] Exemplarily, the battery 160 is transported on the logistics conveyor line 110, passes through each processing station 140 in turn, and at the post-checking station 154 of the logistics conveyor line 110, the processed battery 160 is checked for processing results, and then the target battery 160 that does not meet the target conditions is determined through the check. After the target battery 160 is determined, the transfer magnetic drive structure 114 is automatically controlled to drive the target battery 160 to move along the transfer channel 170 to the supplementary processing waiting station 155. The transfer magnetic drive structure 114 adopts magnetic drive technology to achieve a fast and smooth transfer process. The transfer station 153 is the connection point between the transfer magnetic drive structure 114 and the supplementary processing waiting station 155, which helps the target battery 160 to be transferred to the supplementary processing waiting station 155. The battery 160 located at the supplementary processing waiting station 155 waits to be transferred to the processing station 140, and then the supplementary processing magnetic drive structure 115 is controlled to transport the battery 160 located at the supplementary processing waiting station 155 to the processing station 140. At the processing station 140 , the processing equipment 20 reprocesses the battery 160 to correct errors or problems that occurred during the previous processing and ensure that the quality of the battery 160 meets the target conditions.

[0090] 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 battery processing and transportation process can be automatically controlled and optimized, thereby improving the efficiency and quality of the battery 160 processing.

[0091] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, after controlling the transfer magnetic drive structure 114 to move along the transfer channel 170 to the supplementary processing waiting station 155, the method also includes: controlling the transfer magnetic drive structure 114 to move along the transfer channel 170 to the transfer station 153 to allow other processed batteries 160 to pass through.

[0092] 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 through the transfer magnetic drive structure 114, and the 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, and the other processed batteries 160 enter the next process after passing through the transfer station 153.

[0093] 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 is also responsible for bridging the transfer station 153 on the logistics conveyor line 110 to allow other processed batteries 160 except the target battery 160 to pass through.

[0094] In terms of the 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, preparing for bridging or the next transfer, thereby improving the overall efficiency of the battery 160 processing.

[0095] According to some embodiments of the present application, when the processing equipment 20 is used to process multiple batteries 160, 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, including: when it is determined that the number of batteries 160 located at the supplementary processing waiting station 155 is equal to the single processing volume 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.

[0096] The battery 160 is transported on the logistics conveyor line 110 and passes through each processing station 140 in sequence. At the post-checking station 154 of the logistics conveyor line 110, the processing results of the processed battery 160 are checked. Through the check, the target battery 160 that does not meet the target conditions is determined and transported to the supplementary processing waiting station 155. The transfer magnetic drive structure 114 moves along the transfer channel 170 to the supplementary processing waiting station 155, and transfers the target battery 160 to the 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. The battery 160 located at the supplementary processing waiting station 155 is waiting to be transported to the processing station 140, and the system monitors the number of batteries 160 located at the supplementary processing waiting station 155 in real time.

[0097] In the above description, a group of processed batteries 160 arrives at the post-verification station 154, and a single or multiple target batteries 160 are transferred, and other processed batteries 160 continue to move to the next process along the logistics conveyor line 110, and 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 volume of the processing equipment 20, and then the multiple target batteries 160 located at the supplementary processing waiting station 155 are transported to the processing station 140 through the supplementary processing magnetic drive structure 115. At the processing station 140, the processing equipment 20 re-processes the batteries 160 transferred from the supplementary processing waiting station 155. After the processing is completed, the batteries 160 continue to be transmitted to the post-verification station 154 through the logistics conveyor line 110 for quality inspection.

[0098] This method, combined with the single processing volume of the processing equipment 20, can achieve a more sophisticated battery 160 transportation and processing process. By optimizing the transportation and processing process, it can reduce waiting time and resource waste, and improve the overall efficiency of battery 160 processing.

[0099] According to some embodiments of the present application, when 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 conveyed through the processing conveyor line 120.

[0100] When the number of target batteries 160 at the supplementary processing waiting station 155 is the same as the single processing amount 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 target batteries 160 delivered 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 amount 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 is used to process the unprocessed batteries 160 delivered through the processing conveyor line 120.

[0101] In the above description, when the number of batteries 160 at the processing waiting station 155 is insufficient, the method can flexibly adjust the processing object of the processing equipment 20, reduce waiting time and resource waste, and improve the continuity and efficiency of the production line.

[0102] Specifically, according to some embodiments of the present application, see Figure 1-Figure 6 As shown, the present application provides a battery conveying system 10, a battery processing system, a battery production line and a battery processing method.

[0103] The battery production line includes a battery processing system, which includes a battery conveying system 10 and processing equipment 20.

The magnetic drive structure includes multiple first magnetic drive structures 111, a transfer magnetic drive structure 114 and a supplementary processing magnetic drive structure 115. The first magnetic drive structure 111 is arranged sequentially on the logistics conveying line 110, the transfer magnetic drive structure 114 is installed at the transfer station 153, and the supplementary processing magnetic drive structure 115 is located at the supplementary processing waiting station 155.

[0105] The logistics conveyor line 110 includes a bridging position and a post-verification station 154. The processing conveyor line 120 and the logistics conveyor line 110 are cross-arranged at the bridging position. The post-verification station 154 is located downstream of all the bridging positions. The transfer station 153 is located downstream of the post-verification station 154. The first magnetic drive structure 111 is used for bridging at the bridging position. The post-verification station 154 is used to verify the processing results of the processed batteries 160, and transfer the target batteries 160 that do not meet the target conditions to the supplementary processing waiting station 155.

[0106] Multiple processing conveyor lines 120 are arranged at intervals along the length direction of the logistics conveyor line 110, and are set at intervals in parallel with the transfer channel 170. The supplementary processing waiting station 155 is set at intervals in parallel with the logistics conveyor line 110, and the supplementary processing waiting station 155 is connected to a processing station 140 closest to the transfer station 153.

[0107] The battery processing method is as follows: The processing results of the processed batteries 160 are checked at the post-check station 154 of the logistics conveying line 110, and the target batteries 160 that do not meet the target conditions are determined. Then, when it is determined that the target batteries 160 are 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 is continued to be controlled to move along the transfer channel 170 to the transfer station 153 to allow other processed batteries 160 to pass through, and 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.

[0108] When it is determined that the number of batteries 160 at the supplementary processing waiting station 155 is equal to the single processing amount of the processing equipment 20, the supplementary processing magnetic drive structure 115 is controlled to transport the batteries 160 at the supplementary processing waiting station 155 to the processing station 140. When the number of batteries 160 at the supplementary processing waiting station 155 is less than the single processing amount 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 by the processing conveyor line 120.
