[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. 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.

[0056] 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.

[0057] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. 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.

[0058] 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. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0059] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0060] 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).

[0061] 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. The material of the negative current collector can be copper, and the negative active material can be carbon or silicon, etc. To ensure that a large current can be passed without melting, there are multiple positive electrode tabs stacked together, and there are multiple negative electrode tabs stacked together.

[0062] The separator can be made of PP (polypropylene) or PE (polyethylene), etc. Furthermore, the electrode assembly can be a wound structure or a stacked structure; the embodiments of this application are not limited to these.

[0063] The battery cell may include lithium-ion secondary battery cell, lithium-ion primary battery cell, lithium-sulfur battery cell, sodium lithium-ion battery cell, sodium-ion battery cell, or magnesium-ion battery cell, etc., and the embodiments of this application are not limited to this.

[0064] 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 batteries 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.

[0065] In the battery manufacturing process, there is a liquid injection step. The inventors discovered that in related technologies, a three-axis transport module gripper and a lead screw module are typically used as drives to hold the battery cells for loading and unloading at the liquid injection station. However, the battery cells are energized during the liquid injection process, and the safety performance of the gripper and the speed of the three-axis transport module will affect the safety of the battery cells, posing a risk of cell falling and stacking. Furthermore, the transportation efficiency is slow and the waiting time is long, indicating room for improvement.

[0066] Based on the above considerations, and to address safety issues during battery handling, the inventors, through in-depth research, designed a battery conveying system, a battery processing system, a battery production line, and a battery processing method. This battery conveying system can solve the problems of batteries falling and stacking during handling. Furthermore, it improves loading and unloading efficiency, reduces waiting time, and contributes to increased production efficiency.

[0067] For ease of explanation, the following embodiments use a battery conveying system 10, a battery processing system 1, a battery production line, and a battery processing method from the present application as examples.

[0068] As shown in Figures 1-3, Figure 1 is a structural schematic diagram of a battery delivery system 10 according to an embodiment of this application. Figure 2 is a structural schematic diagram of a clamp 130 of a battery delivery system 10 according to an embodiment of this application. Figure 3 is a partial enlarged view of point A in Figure 2. The battery delivery system 10 includes: a material delivery line 110, a processing delivery line 120, a magnetic drive structure, and a clamp 130. The magnetic drive structure includes a first magnetic drive structure 111, a second magnetic drive structure 112, and a third magnetic drive structure 113. The clamp 130 includes a magnetic element 131 and a support element 132 for carrying a battery 160. The magnetic drive structure is used to drive the clamp 130 through the magnetic element 131.

[0069] Multiple first magnetic drive structures 111 and second magnetic drive structures 112 are arranged sequentially along the material transport line 110, forming a path, responsible for driving the fixture 130 on the material transport line 110 to transport the battery 160 from one position to another. The second magnetic drive structure 112 can be movably installed on the processing transport line 120 between the bridging position 151 and the avoidance position 152. When the second magnetic drive structure 112 is in the bridging position 151, it can dock with the fixture 130 on the material transport line 110, so that the fixture 130 and the battery 160 carried by the fixture 130 can move backward along the material transport line 110. When the second magnetic drive structure 112 is in the avoidance position 152, the second magnetic drive structure 112 does not interfere with other operations on the processing transport line 120.

[0070] The third magnetic drive structure 113 is movably mounted on the processing conveyor line 120 between the bridging position 151 and the processing station 140. When the third magnetic drive structure 113 is in the bridging position 151, it can receive the fixture 130 on the logistics conveyor line 110 and transport it to the processing station 140. When the third magnetic drive structure 113 is in the processing station 140, the battery 160 is processed. After processing is completed, the third magnetic drive structure 113 sends the fixture 130 and the battery 160 back to the bridging position 151 so that they can be sent back to the logistics conveyor line 110.

[0071] In the above description, the battery conveying system 10 is a highly efficient and flexible automated production line configuration for the processing and transportation 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 mutual movement of various magnetic drive structures can flexibly adjust the conveying path of batteries 160 to meet different processing requirements.

[0072] The logistics conveyor line 110 serves as the main channel for transporting the battery 160, responsible for conveying the battery 160 from the starting point to the bridging position 151, and receiving the processed battery 160 from the processing conveyor line 120. The logistics conveyor line 110 is arranged in a straight line along the production line to adapt to the needs of different production scenarios, forming a continuous and stable conveying path. This helps the magnetic drive structure 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 is intersected with the logistics conveyor line 110 at the bridging position 151. It receives the fixture 130 and battery 160 from the logistics conveyor line 110 and performs processing operations. It is also equipped with a second magnetic drive structure 112 and a third magnetic drive structure 113 to facilitate the transfer of the fixture 130 and battery 160, which can reduce the overall footprint of the battery conveying system 10 and improve production efficiency. The fixture 130 includes a magnetic element 131 and a support element 132 for carrying the battery 160. The magnetic element 131 interacts with the magnetic drive structure to drive the fixture 130 to move. The support element 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 second magnetic drive structure 112, and a third magnetic drive structure 113, all of which drive the fixture 130 through the magnetic element 131. This improves the transportation method of the battery 160 and thus enhances the stability of the battery 160 transportation.

[0073] According to some embodiments of this application, referring to FIG4, FIG4 is a structural schematic diagram of the processing conveyor line 120 of the battery conveying system 10 provided in some embodiments of this application. One set of third magnetic drive structures 113, a second magnetic drive structure 112, and another set of third magnetic drive structures 113 are sequentially and movably mounted on the processing conveyor line 120. Referring to FIG6, FIG6 is a structural schematic diagram of the battery processing system 1 provided in some embodiments of this application. Processing stations 140 are provided on both sides of the material conveyor line 110.

[0074] Processing stations 140 are provided on both sides of the logistics conveyor line 110, and the processing stations 140 are located at both ends of the processing conveyor line 120. Two sets of third magnetic drive structures 113 are movably installed on the processing conveyor line 120 between the bridging position 151 and different processing stations 140. When the third magnetic drive structure 113 is located at the bridging position 151, it can receive the fixture 130 on the logistics conveyor line 110 and transport it to the processing station 140. When the third magnetic drive structure 113 is located at the processing station 140, the battery 160 is processed. After the processing is completed, the third magnetic drive structure 113 sends the fixture 130 and the battery 160 back to the bridging position 151 so that they can be sent back to the logistics conveyor line 110.

[0075] The second magnetic drive structure 112 is movably mounted on the processing conveyor line 120 between the bridging position 151 and the avoidance position 152. When the second magnetic drive structure 112 is in the bridging position 151, it can dock with the clamp 130 on the logistics conveyor line 110, so that the clamp 130 and the battery 160 carried by the clamp 130 can move backward along the logistics conveyor line 110. When the second magnetic drive structure 112 is in the avoidance position 152, the second magnetic drive structure 112 does not interfere with other operations on the processing conveyor line 120.

[0076] In the above description, by combining the magnetic drive structure with different conveyor lines, the continuous transfer and processing of the battery 160 between the logistics conveyor line 110 and the processing conveyor line 120 can be achieved.

[0077] According to some embodiments of this application, referring to FIG6, there are multiple processing conveyor lines 120, which are arranged at intervals along the length of the logistics conveyor line 110, and each processing conveyor line 120 corresponds to a processing station 140.

[0078] Multiple processing conveyor lines 120 are arranged at intervals along the length of the logistics conveyor line 110. Each processing conveyor line 120 corresponds to multiple processing stations 140. The processing conveyor lines 120 can operate independently or collaboratively as needed. The processing stations 140 are located at both ends of the processing conveyor lines 120 and are used to perform specific processing operations on the batteries 160. The functions of the processing stations 140 can be customized according to production needs, such as welding, liquid injection, packaging, or testing.

[0079] Each processing conveyor line 120 is sequentially and movably equipped with one set of third magnetic drive structure 113, one set of second magnetic drive structure 112 and another set of third magnetic drive structure 113, for driving the fixture 130 and the battery 160 to move on the conveyor line.

[0080] In the above description, a bridging position 151 is provided between the logistics conveyor line 110 and each processing conveyor line 120 to realize the handover of the fixture 130 and the battery 160. At the bridging position 151, the magnetic drive structure will drive the fixture 130 and the battery 160 to transfer from the logistics conveyor line 110 to the processing conveyor line 120, or from the processing conveyor line 120 back to the logistics conveyor line 110.

[0081] Each processing conveyor line 120 can operate independently or collaboratively to adapt to different production needs. When multiple processing conveyor lines 120 operate in parallel, production efficiency can be improved.

[0082] In actual operation, each processing station 140 has a corresponding third magnetic drive structure 113 to carry the fixture 130, and the second magnetic drive structure 112 is always ready to contact the upstream and downstream logistics conveyor lines 110. When it is necessary to transport the battery 160 downstream, the second magnetic drive structure 112 is located at the bridging position 151 and docks with the fixture 130 on the logistics conveyor line 110. In this way, the fixture 130 and the battery 160 carried by the fixture 130 move backward along the logistics conveyor line 110. At this time, the upstream processing station 140 can be completely unaffected and perform liquid injection synchronously. After the processing is completed, the third magnetic drive structure 113 of the processing station 140 sends the fixture 130 and the battery 160 carried by the fixture 130 back to the bridging position 151 for downstream transportation. The batteries 160 of other processing stations 140 or other batteries 160 on the logistics conveyor line 110 are also unaffected, realizing synchronous operation of each link.

[0083] According to some embodiments of this application, referring to FIG1, at least one first magnetic drive structure 111 is provided between two adjacent bridging positions 151.

[0084] The first magnetic drive structure 111 uses magnetic force to drive the clamp 130 and the battery 160 to move on the conveyor line. At least one first magnetic drive structure 111 is positioned between two adjacent bridging positions 151, enabling continuous and uninterrupted transmission of the battery 160 on the material conveyor line 110, thus improving production efficiency. The first magnetic drive structure 111 can continuously provide power to the clamp 130, allowing it to move smoothly along the material conveyor line 110 and reducing shaking or stagnation of the battery 160 during transmission.

[0085] The bridging position 151 is the junction between the logistics conveyor line 110 and the processing conveyor line 120, used to connect the fixture 130 and the battery 160. At the bridging position 151, the magnetic drive structure will drive the fixture 130 and the battery 160 from the logistics conveyor line 110 to the processing conveyor line 120, or from the processing conveyor line 120 back to the logistics conveyor line 110.

[0086] The first magnetic drive structure 111, which is set between two adjacent bridging positions 151, is responsible for transporting the clamp 130 and the battery 160 from the previous bridging position 151 to the next bridging position 151. During the transport process, the first magnetic drive structure 111 interacts with the magnetic component 131 on the clamp 130 to generate a driving force, so that the clamp 130 and the battery 160 move along the logistics conveyor line 110.

[0087] In the above description, by setting multiple first magnetic drive structures 111 and rationally arranging their number and position between adjacent bridging positions 151, a continuous and stable conveying path can be formed, which helps the magnetic drive structure transport the fixture 130 and the battery 160 on the fixture 130. It can also significantly improve the efficiency of the battery conveying system 10, help reduce the waiting time and stagnation time of the battery 160 during the transmission process, and further improve production efficiency.

[0088] According to some embodiments of this application, referring to Figures 4 and 5, Figure 5 is a partial enlarged view of point B in Figure 4. The processing conveyor line 120 is provided with a slide rail 121 and a slider 122 that slides with the slide rail 121. The second magnetic drive structure 112 and the third magnetic drive structure 113 are slidably mounted on the slide rail 121 through their respective sliders 122. The processing conveyor line 120 is also provided with a drive mechanism for driving the movement of the magnetic drive structures.

[0089] The slide rail 121 is an important component of the processing conveyor line 120, providing a track for the magnetic drive structure to move. The slide rail 121 is designed as a straight line with processing stations 140 at both ends. The material of the slide rail 121 has good wear resistance and corrosion resistance to improve stability and accuracy during long-term use. The slider 122 slides in conjunction with the slide rail 121 to support the magnetic drive structure as it slides on the slide rail 121. The slider 122 is typically equipped with rolling or sliding bearings to reduce friction and wear, and improve sliding efficiency. The slide rail 121 is also equipped with a drive mechanism to drive the magnetic drive structure and the corresponding slider 122 to slide.

[0090] The second magnetic drive structure 112 is slidably mounted on the slide rail 121 via its corresponding slider 122. The second magnetic drive structure 112 slides between the bridging position 151 and the clearance position 152 via the slide rail 121. The third magnetic drive structure 113 is similar to the second magnetic drive structure 112. The third magnetic drive structure 113 is also slidably mounted on the slide rail 121 via its corresponding slider 122. The third magnetic drive structure 113 moves between the bridging position 151 and the processing station 140 via the slide rail 121 to transfer the battery 160 from the logistics conveyor line 110 to the processing conveyor line 120, or from the processing conveyor line 120 to the logistics conveyor line 110. Similarly, the third magnetic drive structure 113 is also equipped with a drive mechanism to realize its movement function.

[0091] The drive mechanism is the power source for the movement of the magnetic drive structure. By providing the necessary torque and speed, it enables the magnetic drive structure to move smoothly along the slide rail 121. Common drive mechanisms include motors, cylinders, and hydraulic cylinders. This drive mechanism can be non-magnetic; in other words, the movement of the second magnetic drive structure 112 and the third magnetic drive structure 113 themselves depends on non-magnetic drive, while the clamps 130 driven by the second magnetic drive structure 112 and the third magnetic drive structure 113 are magnetically driven. This ensures that there is no interference from multiple magnetic fields during the transportation of the battery 160, resulting in high control stability.

[0092] In the above description, the design of the slide rail 121 and the slider 122 enables the magnetic drive structure to move freely on the processing conveyor line 120, and the rapid movement and precise positioning of the magnetic drive structure helps to improve the overall efficiency of the battery delivery system 10.

[0093] According to some embodiments of this application, referring to Figures 2 and 4, each second magnetic drive structure 112 and third magnetic drive structure 113 is adapted to carry multiple clamps 130, each group of third magnetic drive structures 113 includes multiple clamps arranged side by side, and each group of second magnetic drive structures 112 includes multiple clamps arranged side by side.

[0094] The magnetic drive structure includes a first magnetic drive structure 111, a second magnetic drive structure 112, and a third magnetic drive structure 113. Both the second magnetic drive structure 112 and the third magnetic drive structure 113 are suitable for carrying multiple clamps 130, allowing for the processing and transfer of multiple batteries 160 in a single movement, thereby significantly improving production efficiency. The clamps 130 can firmly hold the batteries 160, reducing shaking or detachment during movement.

[0095] Both the second magnetic drive structure 112 and the third magnetic drive structure 113 employ multiple units arranged side by side. This layout can improve the stability and balance of the magnetic drive structure during movement, and also improve production efficiency.

[0096] The second magnetic drive structure 112 slides between the bridging position 151 and the avoidance position 152, and the third magnetic drive structure 113 moves between the bridging position 151 and the processing station 140 to transfer the battery 160 from the logistics conveyor line 110 to the processing conveyor line 120, or from the processing conveyor line 120 to the logistics conveyor line 110.

[0097] In the above description, by simultaneously carrying and moving multiple clamps 130 using a magnetic drive structure, the processing efficiency of the battery 160 can be significantly improved, which helps to shorten the production cycle and improve overall production efficiency. The design of the magnetic drive structure also helps to reduce damage caused by shaking or collision, thereby improving product quality.

[0098] According to some embodiments of this application, as shown in FIG6, this application also provides a battery processing system 1, including a battery conveying system 10 of any of the above schemes and a processing device, the processing device being used to process a battery 160 located at a processing station 140.

[0099] The battery conveying system 10 includes key components such as slide rail 121, slider 122, second magnetic drive structure 112, third magnetic drive structure 113, and fixture 130. It is responsible for transferring batteries 160 between the logistics conveying line 110 and the processing station 140. Through multiple magnetic drive structures and fixtures 130 arranged side by side, the battery conveying system 10 can process multiple batteries 160 at the same time, thereby improving production efficiency.

[0100] The processing equipment is used to perform various processing operations on the battery 160 located at processing station 140. The type and function of the processing equipment depend on the specific battery 160 production process and requirements. For example, in the electric vehicle battery manufacturing process, the processing equipment can be a welding machine, a liquid injection machine, and a packaging machine, etc., used to perform welding, liquid injection, or packaging processes on the battery 160 located at processing station 140.

[0101] In the above description, the battery 160 is first transported to the bridging position 151 via the material conveyor line 110. Then, the second magnetic drive structure 112 and the third magnetic drive structure 113 work together to accurately transport the fixture 130 and the battery 160 to the designated processing station 140 via the slide rail 121 and the slider 122. When the battery 160 arrives at the processing station 140, the processing equipment begins to process the battery 160. After processing is completed, the third magnetic drive structure 113 transfers the fixture 130 and the battery 160 from the processing station 140 to the bridging position 151 and transports them to the next process via the material conveyor line 110.

[0102] With multiple magnetic drive structures and fixtures 130 arranged side by side, the battery processing system 1 can process multiple batteries 160 simultaneously, thereby improving production efficiency. At the same time, the coordinated operation of the battery conveying system 10 and the processing equipment helps to reduce battery damage or quality problems caused by processing errors.

[0103] According to some embodiments of this application, the processing equipment is processing equipment 20, used for injecting liquid into the battery 160 located at processing station 140.

[0104] The battery transport system 10 is responsible for transporting the battery 160 between the logistics transport line 110 and the processing station 140. Through components such as the slide rail 121, slider 122, second magnetic drive structure 112, third magnetic drive structure 113 and fixture 130, the battery transport system 10 can ensure the stability and accuracy of the battery 160 during the transport process.

[0105] For example, the processing equipment can be processing equipment 20, used to inject electrolyte into the battery 160 located at processing station 140. Processing equipment 20 typically includes key components such as an injection head, an injection pump, an electrolyte storage tank, and a control system. The injection head is used to accurately align with the injection port of the battery 160, reducing the risk of electrolyte leakage or inaccurate injection. The injection pump is responsible for providing a stable injection pressure, enabling the electrolyte to be injected into the battery 160 evenly and quickly. The electrolyte storage tank is used to store and supply electrolyte, and its capacity and material are selected according to production needs and electrolyte characteristics. The control system is responsible for monitoring the injection process to achieve precise control of the injection volume, injection speed, and injection pressure.

[0106] In the above description, through the coordinated operation of the battery delivery system 10 and the processing equipment 20, the battery processing system 1 can process multiple batteries 160 simultaneously, thereby improving production efficiency. At the same time, the high precision and stability of the processing equipment 20 can ensure the speed and accuracy of the liquid injection process, which helps to reduce battery 160 damage or quality problems caused by liquid injection errors.

[0107] According to some embodiments of this application, this application also provides a battery production line, including a battery processing system 1 of any of the above schemes.

[0108] 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, battery processing system 1 is mainly responsible for the core processing of battery 160, such as liquid injection, packaging and welding.

[0109] For example, in a battery production line, the battery processing system 1 includes a battery conveying system 10 and processing equipment, which, together with other auxiliary equipment and processes, complete the processing of the battery 160. The processing equipment, which can be processing equipment 20, is 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 transporting the battery 160 from the pretreatment station to the electrolyte injection station, and after electrolyte injection, transporting it to the next processing stage. The battery processing system 1 may also include packaging equipment and welding equipment. The packaging equipment is used to package the battery 160 after electrolyte injection to improve the sealing and safety of the battery 160. The welding equipment is used to weld the internal connectors of the battery 160 to ensure reliable electrical connections within the battery 160.

[0110] In the above description, the process flow on the battery 160 production line includes pretreatment, electrolyte injection, encapsulation, welding, and post-processing and quality inspection. Pretreatment involves cleaning and deburring the battery 160 to prepare it for electrolyte injection. Electrolyte injection involves injecting electrolyte into the battery 160 to prepare it 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 aging tests or performance tests on the encapsulated and welded battery 160 to ensure that its quality meets standards.

[0111] 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.

[0112] According to some embodiments of this application, as shown in Figures 1 and 6, this application also provides a battery processing method using a battery processing system 1, comprising:

[0113] If it is determined that there is no battery 160 to be processed at the first processing station 141, the second magnetic drive structure 112 corresponding to the first processing station 141 is controlled to move along the processing conveyor line 120 in a direction away from the first processing station 141 to the avoidance position 152, and the third magnetic drive structure 113 at the first processing station 141 is controlled to move along the processing conveyor line 120 to the bridging position 151 corresponding to the first processing station 141; the clamp 130 at the loading buffer position of the logistics conveyor line 110 is controlled to carry the battery 160 to be processed and transport it to the third magnetic drive structure 113 at the bridging position 151; the third magnetic drive structure 113 at the bridging position 151 corresponding to the first processing station 141 is controlled to move along the processing conveyor line 120 to the first processing station 141; and the processing equipment at the first processing station 141 is controlled to process the battery 160 to be processed at the first processing station 141.

[0114] First, it is checked whether there is a battery 160 to be processed at the first processing station 141. This step is usually achieved by a sensor or control system to ensure that the loading operation is only performed when the first processing station 141 is idle. After determining that there is no battery 160 to be processed at the first processing station 141, the second magnetic drive structure 112 corresponding to the first processing station 141 is controlled to move along the processing conveyor line 120 in a direction away from the first processing station 141 to the avoidance position 152. This step is to make room for the subsequent bridging operation of the third magnetic drive structure 113 at the bridging position 151, so as to avoid interference between the second magnetic drive structure 112 and the third magnetic drive structure 113. Then, the third magnetic drive structure 113 at the first processing station 141 is controlled to move along the processing conveyor line 120 to the bridging position 151 corresponding to the first processing station 141. The bridging position 151 is a transition area between the logistics conveyor line 110 and the processing conveyor line 120. The battery to be processed 160 is transferred from the logistics conveyor line 110 to the processing conveyor line 120, or the processed battery 160 is transferred from the processing conveyor line 120 to the logistics conveyor line 110, mainly through the cooperation of the second magnetic drive structure 112 and the third magnetic drive structure 113 at the bridging position 151.

[0115] After the above preparation operations are completed, the loading operation is performed. The loading buffer position is located upstream of the bridging position 151. The clamp 130 at the loading buffer position of the logistics conveyor line 110 is controlled to carry the battery 160 to be processed and transport it to the third magnetic drive structure 113 at the bridging position 151. This step realizes the initial transfer of the battery 160 to be processed from the logistics conveyor line 110 to the processing conveyor line 120. Subsequently, the third magnetic drive structure 113 at the bridging position 151 corresponding to the first processing station 141 is controlled to move along the processing conveyor line 120 to the first processing station 141. This step can transport the battery 160 to be processed from the bridging position 151 to the first processing station 141, ready for processing. Finally, the processing equipment at the first processing station 141 is controlled to process the battery 160 at the first processing station 141.

[0116] In the above description, the third magnetic drive structure 113 can move flexibly along the processing conveyor line 120, which can reach the bridging position 151 to dock with the logistics conveyor line 110, or transport the battery to be processed 160 to the processing station 140, thereby reducing the damage or positional displacement of the battery 160 during transportation and improving the overall production efficiency of the battery production line.

[0117] According to some embodiments of this application, after the processing equipment processes the battery 160 to be processed at the first processing station 141, the method further includes:

[0118] When the second magnetic drive structure 112 is in the avoidance position 152 away from the first processing station 141, the third magnetic drive structure 113 at the first processing station 141 is controlled to move along the processing conveyor line 120 to the bridging position 151.

[0119] The control system drives the clamp 130 on the third magnetic drive structure 113 to the downstream of the logistics conveyor line 110.

[0120] After the processing equipment completes the processing of the battery 160 at the first processing station 141, it is first confirmed whether the second magnetic drive structure 112 is located in the clearance position 152 away from the first processing station 141, to ensure that the second magnetic drive structure 112 will not interfere with the third magnetic drive structure 113 when transporting the processed battery 160. When the second magnetic drive structure 112 is in the clearance position 152, the third magnetic drive structure 113 at the first processing station 141 is controlled to move along the processing conveyor line 120 to the bridging position 151. This step is to transport the processed battery 160 from the first processing station 141 to the bridging position 151 that connects with the logistics conveyor line 110. At this time, the third magnetic drive structure 113 and the first magnetic drive structure 111 form a path on the logistics conveyor line 110 so as to control the third magnetic drive structure 113 and the first magnetic drive structure 111 to drive the clamp 130 on the third magnetic drive structure 113 to the downstream of the logistics conveyor line 110. This step can realize the transfer of the processed battery 160 from the processing conveyor line 120 to the logistics conveyor line 110, and prepare for subsequent operations.

[0121] In the above description, the third magnetic drive structure 113 and the first magnetic drive structure 111 work together to drive the fixture 130 downstream of the material conveyor line 110. The third magnetic drive structure 113 is responsible for transporting the fixture 130 from the processing station 140 to the bridging position 151, and the first magnetic drive structure 111 is responsible for pushing the fixture 130 from the bridging position 151 onto the material conveyor line 110. By automatically controlling the movement of the third magnetic drive structure 113 and the first magnetic drive structure 111, the processed battery 160 can be quickly transported from the processing station 140 to the downstream of the material conveyor line 110, thereby improving production efficiency.

[0122] According to some embodiments of this application, when the processing conveyor lines 120 are a plurality of ones spaced apart along the length of the logistics conveyor line 110, and when it is determined that there is no battery 160 to be processed at the second processing station 142, the method further includes:

[0123] The system controls the second magnetic drive structure 112 upstream of the second processing station 142 to remain at the bridging position 151, controls the second magnetic drive structure 112 corresponding to the second processing station 142 to move along the processing conveyor line 120 in a direction away from the second processing station 142 to the avoidance position 152, and controls the third magnetic drive structure 113 at the second processing station 142 to move along the processing conveyor line 120 to the bridging position 151; controls the clamp 130 at the loading buffer position to carry the battery 160 to be processed to the third magnetic drive structure 113 at the bridging position 151 corresponding to the second processing station 142; controls the third magnetic drive structure 113 at the bridging position 151 corresponding to the second processing station 142 to move along the processing conveyor line 120 to the second processing station 142; and controls the processing equipment at the second processing station 142 to process the battery 160 to be processed at the second processing station 142.

[0124] First, check if there is a battery 160 to be processed at the second processing station 142. If it is determined that there is no battery 160 to be processed, proceed to the next step. Control the second magnetic drive structure 112 upstream of the second processing station 142 to be held at the bridging position 151. The second magnetic drive structure 112 upstream of the second processing station 142 is the same as the second magnetic drive structure 112 corresponding to the first processing station 141, to ensure that the battery 160 to be processed upstream can be smoothly transported to the bridging position 151 corresponding to the second processing station 142, in preparation for subsequent transfer.

[0125] Then, the second magnetic drive structure 112 corresponding to the second processing station 142 is controlled to move along the processing conveyor line 120 in a direction away from the second processing station 142 to the avoidance position 152. This step is to make room for the subsequent bridging operation to avoid interference with the third magnetic drive structure 113 at the second processing station 142. The third magnetic drive structure 113 at the second processing station 142 is controlled to move along the processing conveyor line 120 to the bridging position 151, ready to receive the battery 160 to be processed from upstream. At the bridging position 151, the clamp 130 at the loading buffer position is controlled to carry the battery 160 to be processed and transport it to the third magnetic drive structure 113 at the bridging position 151 corresponding to the second processing station 142, so as to realize the transfer of the battery 160 from upstream to the bridging position 151.

[0126] Subsequently, the third magnetic drive structure 113 at the bridging position 151 corresponding to the second processing station 142 is controlled to move along the processing conveyor line 120 to the second processing station 142. This step transports the battery 160 to be processed from the bridging position 151 to the second processing station 142, ready for processing. Finally, the processing equipment at the second processing station 142 is controlled to process the battery 160 to be processed at the second processing station 142.

[0127] In the above description, the second magnetic drive structure 112 corresponding to the first processing station 141 is held at the bridging position 151, which ensures the smooth transport of the battery 160 to be processed. The third magnetic drive structure 113 corresponding to the second processing station 142 moves flexibly between the bridging position 151 and the second processing station 142, which enables the smooth transfer of the battery 160 to be processed.

[0128] Specifically, according to some embodiments of this application, please continue to refer to Figures 1-6, this application provides a battery conveying system 10, a battery processing system 1, a battery production line, and a battery processing method.

At least one set of third magnetic drive structures 113 is mounted on the processing transport line 120 and can move between the bridging position 151 and the processing station 140. Furthermore, each second magnetic drive structure 112 and each third magnetic drive structure 113 is adapted to carry multiple fixtures 130.

[0131] Multiple processing conveyor lines 120 are arranged at intervals along the length of the spacing and intersect with the logistics conveyor line 110 at bridging positions 151. Each processing conveyor line 120 corresponds to two processing stations 140. The processing conveyor line 120 is equipped with a slide rail 121 and a slider 122 that slides with the slide rail 121.

Then, the clamp 130 at the loading buffer position of the logistics conveyor line 110 is controlled to carry the battery 160 to be processed to the third magnetic drive structure 113 at the bridging position 151. Then, the third magnetic drive structure 113 at the bridging position 151 corresponding to the first processing station 141 is controlled to move along the processing conveyor line 120 to the first processing station 141. Finally, the processing equipment at the first processing station 141 is controlled to process the battery 160 to be processed at the first processing station 141.

[0134] After the processing equipment processes the battery 160 to be processed at the first processing station 141, if the second magnetic drive structure 112 is located at the avoidance position 152 away from the first processing station 141, the third magnetic drive structure 113 at the first processing station 141 is controlled to move along the processing conveyor line 120 to the bridging position 151. Then, the third magnetic drive structure 113 and the first magnetic drive structure 111 are controlled to drive the fixture 130 on the third magnetic drive structure 113 to the downstream of the logistics conveyor line 110.

[0135] The above describes the process of processing the battery 160 at the first processing station 141. The processing conveyor lines 120 are multiple lines spaced apart along the length of the spacing. If it is determined that there is no battery 160 to be processed at the second processing station 142, the process of processing the battery 160 at the second processing station 142 is carried out.
