Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing technology, specifically to a lithium battery core transportation device and core logistics system. Background Technology

[0002] As a crucial step in the assembly stage of lithium battery manufacturing, the efficient transport of the cut-and-roll cores not only impacts production efficiency but also poses product quality risks. Properly transporting the cut-and-roll cores to the logistics line and transferring them to the next process is of paramount importance to the overall operation of the production line.

[0003] When producing different models of cores through winding, if they are fed into the same material handling line, different models of cores will end up in the same automated storage and retrieval system, resulting in mixing of different models. To avoid this mixing problem, one approach is to produce different models of cores separately during day and night shifts, but this increases labor costs, equipment energy consumption, and environmental costs. Another approach is to provide multiple material handling lines, with different models of cores fed into different material handling lines, but this significantly increases equipment investment costs. These shortcomings in the lithium battery assembly process lead to higher production costs for lithium batteries, thus significantly increasing the overall cost of lithium battery products.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0033] In the production process of lithium batteries, batteries are typically classified and manufactured according to different models and specifications. However, due to human error or other reasons on the production line, batteries of different models and specifications may be mixed together, resulting in mixed materials. This is especially true in the lithium battery assembly stage. When cutting and rolling different models of cores, if the same material is used for feeding, different models of cores may be fed into the same automated storage and retrieval system (AS / RS), leading to mixing of different core models and consequently, mixed materials in the assembled lithium batteries. This mixing of materials, resulting in different models of lithium batteries being shipped together in the same batch, poses a serious safety hazard.

[0034] Taking Type A and Type B cores as examples, to avoid mixing of materials between Type A and Type B cores, the following methods can be used: Figure 1 The logistics line shown in the diagram performs unilateral feeding in batches on different conveyor lines.

[0035] like Figure 1 As shown, winding machines 1 to 4 are located on one side of the loading section 3 of the logistics line 1 and are configured to produce type A winding cores; winding machines 5 to 8 are located on the other side of the loading section 3 of the logistics line 1 and are configured to produce type B winding cores. Type A and type B winding cores are unloaded from the unloading section 5 of the logistics line 1 via type A winding core transport line 6 and type B winding core transport line 7, respectively, into different automated storage and retrieval systems.

[0036] When producing type A cores, only winding machines 1 through 4 (2) are in operation. During this time, winding machines 5 through 8 (4) cease production. This ensures that the entire loading section 3 of logistics line 1 contains only type A cores, and the type A cores are unloaded from the unloading section 5 of logistics line 1 via the type A core transport line 6. Similarly, when producing type B cores, only winding machines 5 through 8 (4) are in operation. During this time, winding machines 1 through 4 (2) cease production. This ensures that the entire loading section 3 of logistics line 1 contains only type B cores, and the type B cores are unloaded from the unloading section 5 of logistics line 1 via the type B core transport line 7. Although this double-shift production method avoids mixing type A and type B cores during unloading, it only allows for single-sided production, leading to reduced equipment utilization and production efficiency, increased labor costs, equipment energy consumption, and environmental costs, ultimately resulting in higher product costs.

[0037] To address the aforementioned technical problems, the embodiments of this application provide... Figure 1 The logistics line shown is improved to provide a core transport device and a core logistics system, as described in the following embodiments.

[0038] like Figure 2 As shown, this embodiment of the present invention provides a core transport device 10, which includes a core loading mechanism 11, a core transport mechanism 12, a core identification mechanism 13, and a connecting transport mechanism 14. The core transport mechanism 12 includes a loading transport line 15 and a unloading transport line 16, with the output end 15a of the loading transport line 15 located close to the input end 16a of the unloading transport line 16. The connecting transport mechanism 14 is located between the output end 15a of the loading transport line 15 and the input end 16a of the unloading transport line 16. The transport direction of the loading transport line 16 is X1.

[0039] A core loading mechanism 11 is disposed on at least one side of the loading conveyor line 15 and configured to output multiple cores of different models to the loading conveyor line 15. A core identification mechanism 13 is disposed near the output end 15a of the loading conveyor line 15 and electrically connected to the connecting conveyor mechanism 14, and is configured to identify the model of the target core 18 and output an identification signal to the connecting conveyor mechanism 14. The unloading conveyor line 16 includes multiple independently disposed sub-unloading conveyor lines 17, each sub-unloading conveyor line 17 is configured to transport cores of the same model, and the input end 16a of each sub-unloading conveyor line 17 is disposed near the connecting conveyor mechanism 14. The connecting conveyor mechanism 14 is configured to receive the identification signal and transfer the target core 18 located at the output end 15a of the loading conveyor line 15 to the corresponding sub-unloading conveyor line 17 according to the received identification signal.

[0040] Understandably, the number of sub-feeding transport lines 17 is the same as the number of roll core models, meaning that each roll core model is fed through one sub-feeding transport line 17. Furthermore, at least some components of the connecting transport mechanism 14 can move between the input ends 16a of the multiple sub-feeding transport lines 17, allowing the connecting transport mechanism 14 to connect with the input end 16a of one of the sub-feeding transport lines 17. This transfers the identified target roll core 18 from the output end 15a of the loading transport line 15 to the input end 16a of the corresponding sub-feeding transport line 17, thereby achieving automatic feeding of roll cores of different models.

[0041] This embodiment of the utility model will take the unloading of two different types of cores as an example to specifically explain the structure and working principle of the core transport mechanism 12.

[0042] In some embodiments, the core feeding mechanism 11 includes a plurality of first winding mechanisms 11a and a plurality of second winding mechanisms 11b. The plurality of first winding mechanisms 11a are disposed on a first side 15b of the feeding conveyor line 15, and the plurality of second winding mechanisms 11b are disposed on a second side 15c of the feeding conveyor line 15, with the first side 15b and the second side 15c being disposed opposite to each other. The first winding mechanisms 11a are configured to output a first core 18a to the feeding conveyor line 15, and the second winding mechanisms 11b are configured to output a second core 18b to the feeding conveyor line 15, wherein the first core 18a and the second core 18b are of different types.

[0043] It should be noted that the number of the first winding mechanism 11a and the second winding mechanism 11b in this embodiment of the utility model is not limited. The figure only shows 8 first winding mechanisms 11a (e.g., winding mechanisms 1#-8#) and 8 second winding mechanisms 11b (winding mechanisms 9#-16#), but it is not limited to this.

[0044] Understandably, multiple first winding mechanisms 11a and multiple second winding mechanisms 11b can operate simultaneously, enabling the production of two types of cores per shift. This effectively improves production efficiency and equipment utilization, while reducing labor and environmental costs, thus saving production costs and consequently reducing product costs.

[0045] In one specific embodiment, the first winding mechanism 11a includes a first winding machine and a first feeding assembly. The first winding machine is configured to produce a first core 18a, and the first feeding assembly is configured to transfer the first core 18a produced by the first winding machine onto the feeding conveyor line 15. Similarly, the second winding mechanism 11b includes a second winding machine and a second feeding assembly. The second winding machine is configured to produce a second core 18b, and the second feeding assembly transfers the second core 18b produced by the second winding machine onto the feeding conveyor line 15.

[0046] In one specific embodiment, the first feeding component and the second feeding component can be robotic arms with a material-grabbing section at the end, but are not limited thereto.

[0047] Of course, in some embodiments, the first feeding component can be part of the first winding machine, and the second feeding component can be part of the second winding machine. In this case, the first winding mechanism 11a is the first winding machine, and the second winding mechanism 11b is the second winding machine.

[0048] It should be noted that the present invention does not limit the structure of the first winding mechanism 11a and the second winding mechanism 11b, as long as the first core 18a and the second core 18b can be output to the feeding and conveying line 15.

[0049] Correspondingly, the unloading transport line 16 includes a first sub-unloading transport line 17a and a second sub-unloading transport line 17b. The first core 18a is transferred from the output end 15a of the loading transport line 15 to the input end 16a of the first sub-unloading transport line 17a via the connecting transport mechanism 14, and the second core 18b is transferred from the output end 15a of the loading transport line 15 to the input end 16a of the second sub-unloading transport line 17b via the connecting transport mechanism 14.

[0050] The first sub-feeding conveyor line 17a has a transport direction of X2, and the second sub-feeding conveyor line 17b has a transport direction of X3.

[0051] It should be noted that both the first sub-feeding conveyor line 17a and the second sub-feeding conveyor line 17b can be single-layer or multi-layer conveyor lines. When the first sub-feeding conveyor line 17a and the second sub-feeding conveyor line 17b are multi-layer conveyor lines, the conveying capacity of the first sub-feeding conveyor line 17a and the second sub-feeding conveyor line 17b can be increased, which is beneficial to improving the feeding efficiency.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, the first core 18a and the second core 18b are placed in opposite directions on the feeding conveyor line 15, that is, they face opposite directions. Both the first core 18a and the second core 18b have a first electrode 19 and a second electrode 20. The first electrode 19 of the first core 18a is positioned closer to the first side 15b, and the first electrode 19 of the second core 18b is positioned closer to the second side 15c. The first electrode 19 has a characteristic color different from the second electrode 20.

[0053] Understandably, since the first winding mechanism 11a and the second winding mechanism 11b are respectively located on both sides of the feeding conveyor line 15, the first core 18a output by the first winding mechanism 11a and the second core 18b output by the second core 18b mechanism are placed in opposite directions. That is to say, the first core 18a and the second core 18b are placed upside down on the feeding conveyor line 15.

[0054] In one specific embodiment, such as Figure 3 As shown, the second electrode 20 of the first core 18a is disposed near the second side 15c of the feeding conveyor line 15, and the second electrode 20 of the second core 18b is disposed near the first side 15b of the feeding conveyor line 15. That is, the first electrode 19 and the second electrode 20 on the first core 18a are respectively located on opposite sides of the first core 18a.

[0055] In another specific embodiment, such as Figure 4 As shown, the second electrode 20 of the first core 18a is also located near the first side 15b of the feeding conveyor line 15, and the second electrode 20 of the second core 18b is also located near the second side 15c of the feeding conveyor line 15. That is to say, the first electrode 19 and the second electrode 20 on the first core 18a are located on the same side.

[0056] In one specific embodiment, the first electrode 19 is the negative electrode, and the material of the first electrode 19 is copper foil; the second electrode 20 is the positive electrode, and the material of the second electrode 20 is aluminum foil. Because the negative electrode is made of copper foil, it has the characteristic copper color of copper foil. Copper foil is purplish-red in its normal state, therefore the characteristic color of the first electrode 19 of the first core 18a and the second core 18b is purplish-red.

[0057] Of course, in other embodiments, the first electrode 19 can be a positive electrode, and the second electrode 20 can be a negative electrode. It is understood that since the positive electrode material is aluminum foil, the positive electrode has the characteristic silvery-white color of aluminum foil; if the first electrode 19 is a positive electrode, the characteristic color is silvery-white. This embodiment of the invention uses the first electrode 19 as a negative electrode as an example for explanation.

[0058] It should be noted that the materials of the first electrode 19 and the second electrode 20 can also be conductive materials of different colors, and this application does not limit this.

[0059] In some embodiments, such as Figure 2 As shown, the core identification mechanism 13 includes at least one color mark sensor 21 disposed at the output end 15a of the feeding conveyor line 15 and near the first side 15b. Figure 5As shown, when the target roll core 18 is transported to the output end 15a of the feeding conveyor line 15, the target roll core 18 is aligned with a color mark sensor 21. The color mark sensor 21 is configured to identify the color of the target roll core 18 near the first side 15b, and is configured to output a first electrical signal and a second electrical signal to the connecting conveyor mechanism 14 respectively based on whether the characteristic color is identified. The first electrical signal and the second electrical signal are the identification signals described above.

[0060] Understandably, since the color mark sensor 21 is located close to the first side 15b, the color mark sensor 21 can be used to identify the color of the side of the target core 18 that is close to the first side 15b. In other words, the color mark sensor 21 identifies the first electrode (negative electrode) 19 by identifying the characteristic color, and determines the model of the target core 18 based on whether the first electrode (negative electrode) 19 is identified.

[0061] When the color mark sensor 21 detects the characteristic purplish-red color, it indicates that the first electrode 19 of the target core 18 is located close to the first side 15b, proving that the target core 18 is the first core 18a. At this time, the color mark sensor 21 outputs the first electrical signal to the connecting transport mechanism 14.

[0062] When the color mark sensor 21 does not recognize the characteristic purplish-red color, it indicates that the first electrode 19 of the target core 18 is located close to the second side 15c, proving that the target core 18 is the second core 18b. At this time, the color mark sensor 21 outputs a second electrical signal to the connecting transport mechanism 14.

[0063] When the connecting transport mechanism 14 receives the first electrical signal, it connects to the input terminal 16a of the first sub-unloading transport line 17a and is configured to transfer the target core 18 onto the first sub-unloading transport line 17a, so that the target core 18 (first core 18a) is unloaded through the first sub-unloading transport line 17a. When the connecting transport mechanism 14 receives the second electrical signal, it connects to the input terminal 16a of the second sub-unloading transport line 17b and is configured to transfer the target core 18 onto the second sub-unloading transport line 17b, so that the target core 18 (second core 18b) is unloaded through the second sub-unloading transport line 17b. This method enables accurate identification of the first core 18a and the second core 18b, allowing them to be automatically unloaded through different sub-unloading transport lines 17, effectively improving unloading efficiency and avoiding material mixing problems.

[0064] In some embodiments, such as Figures 3 to 6 As shown, the core transport mechanism 12 also includes multiple moving units 22. The cores output by the core feeding mechanism 11 are placed on the moving units 22 and transported to the output end 15a of the feeding transport line 15 by the movement of the moving units 22.

[0065] In some embodiments, the moving unit 22 is provided with at least one clamp, configured to fix the target core 18.

[0066] In some embodiments, each moving unit 22 is provided with multiple clamps configured to hold multiple target cores 18 of the same type. It is understood that placing cores output from winding machines located on the same side of the feeding conveyor line 15 on the same moving unit 22 is beneficial to improving unloading efficiency.

[0067] In some embodiments, such as Figure 2 As shown, the connecting transport mechanism 14 includes a connecting servo 23 and a transfer unit 24. The connecting servo 23 is electrically connected to the core identification mechanism 13 and is configured to receive a first electrical signal or a second electrical signal. Based on the received first or second electrical signal, the connecting servo 23 moves the transfer unit 24 to connect with the corresponding sub-unloading transport line 17. In the above process, the target core 18 identified by the core identification mechanism 13 can move from the output end 15a of the loading transport line 15 to the transfer unit 24 with the moving unit 22, and then move from the transfer unit 24 to the corresponding sub-unloading transport line 17, thereby realizing automatic sorting and unloading of cores of different models.

[0068] Understandably, in the initial state, the transfer unit 24 is connected to the output end 15a of the loading conveyor line 15. When the moving unit 22 carrying the target core 18 moves from the output end 15a of the loading conveyor line 15 to the transfer unit 24 of the connecting conveyor mechanism 14, the connecting servo 23 drives the transfer unit 24 to move to connect with the first sub-unloading conveyor line 17a or the second sub-unloading conveyor line 17b according to the first electrical signal or the second electrical signal, so that the moving unit 22 carrying the target core 18 moves from the transfer unit 24 to the first sub-unloading conveyor line 17a or the second sub-unloading conveyor line 17b.

[0069] In some embodiments, the core transport mechanism 12 is a magnetic levitation transport mechanism, that is, both the loading transport line 15 and the unloading transport line 16 are magnetic levitation transport lines; and the connecting transport mechanism 14 is a magnetic levitation connecting transport mechanism.

[0070] Understandably, the loading conveyor line 15, the unloading conveyor line 16, and the transfer unit 24 all include at least one magnetic levitation stator assembly 25, and the moving unit 22 is a magnetic levitation mover assembly 26. The magnetic levitation mover assembly 26 can be displaced by magnetic force on the magnetic levitation stator assembly 25 in the loading conveyor line 15, the connecting conveyor mechanism 14, and the unloading conveyor line 16.

[0071] In some embodiments, a preset number of target cores 18 are carried on the magnetic levitation actuator 26 by a plurality of clamps. When the magnetic levitation actuator 26 is located at the output end 15a of the feeding conveyor line 15, the core identification mechanism 13 is aligned with the preset number of target cores 18 on the magnetic levitation actuator 26 and simultaneously identifies the preset number of target cores 18.

[0072] In some embodiments, the preset quantity can be 1, 2, 3, 4, 5, or 6, but is not limited thereto. It is understood that the embodiments of this application do not limit the number of cores on each magnetic levitation actuator assembly 26.

[0073] In some embodiments, such as Figure 6 As shown, the loading and unloading conveyor lines 15 and 16 also include support lines 27 extending along the transport direction. Multiple magnetic levitation stator assemblies 25 are distributed along the transport direction on the support lines 27. The magnetic levitation mover assembly 26 is located on the side of the magnetic levitation stator assembly 25 away from the support lines 27 and moves by being driven by a magnetic field.

[0074] Of course, the loading conveyor line 15, the unloading conveyor line 16 and the transfer unit 24 also include a driver electrically connected to the magnetic levitation stator assembly 25 and a controller electrically connected to the driver, which are configured to precisely control the position of the magnetic levitation mover assembly 26.

[0075] In one specific embodiment, the magnetic levitation mover assembly 26 includes a mover body, a support member, and a guide member; one end of the guide member is connected to the support member, and the other end is rotatably connected to the magnetic levitation stator assembly 25 or the support line 27; the mover body is fixed to the support member and suspended on the magnetic levitation stator assembly 25; the support member is configured to accommodate the target winding core 18. Under the action of magnetic force, the mover body can move along the length direction of the magnetic levitation stator assembly 25, thereby driving the support member and the guide member to move. It should be noted that magnetic levitation is prior art, and the levitation principle and driving principle between the mover body and the magnetic levitation stator are not described in detail here.

[0076] In some embodiments, the support member may be a housing located on the periphery of the mover body, and the guide member may include at least one roller, but is not limited thereto.

[0077] In some embodiments, the transfer unit 24 includes a support member and a magnetic levitation stator assembly 25. The support member is connected to the connection servo 23, and the magnetic levitation stator assembly 25 is located on the support member and fixedly connected to the support member. The connection servo 23 controls the synchronous movement of the support member and the magnetic levitation stator assembly 25 fixed on the support member by switching the movement direction, thereby realizing that the output end of the connection transport mechanism 14 is connected to the input end 16a of the first sub-unloading transport line 17a or the second sub-unloading transport line 17b, so that the magnetic levitation moving part assembly 26 carrying the target core 18 can be moved to the corresponding sub-unloading transport line 17 through the magnetic levitation stator assembly 25 in the connection transport mechanism 14, and transported and unloaded by the magnetic levitation stator assembly 25 on the corresponding sub-unloading transport line 17.

[0078] In some embodiments, such as Figure 2 As shown, the first sub-unloading conveyor line 17a and the second sub-unloading conveyor line 17b are arranged on the same layer and spaced apart from each other. At this time, the connection servo 23 in the connection conveyor mechanism 14 is a horizontal connection servo. That is to say, the connection servo 23 in the connection conveyor mechanism 14 can drive the support member and the magnetic levitation stator assembly 25 fixed on the support member to move in the horizontal direction, thereby realizing the connection with the input end 16a of the first sub-unloading conveyor line 17a or the second sub-unloading conveyor line 17b.

[0079] In other embodiments, the first sub-unloading conveyor line 17a and the second sub-unloading conveyor line 17b are at least partially stacked, and the connection servo 23 in the connection conveyor mechanism 14 is a vertical connection servo. That is, the connection servo 23 in the connection conveyor mechanism 14 can drive the support member and the magnetic levitation stator assembly 25 fixed on the support member to move in the vertical direction, thereby achieving communication with the input end 16a of the first sub-unloading conveyor line 17a or the second sub-unloading conveyor line 17b.

[0080] Understandably, the connecting servo 23 in the connecting transport mechanism 14 is electrically connected to the core identification mechanism 13, and switches the position of the support and the magnetic levitation stator assembly 25 fixed on the support by receiving electrical signals.

[0081] In some embodiments, such as Figure 2 As shown, the core transport mechanism 12 also includes a return transport line 28 located between the loading transport line 15 and the unloading transport line 16. The transport direction X1 of the loading transport line 15 and the transport direction X1' of the return transport line 28 are opposite. The magnetic levitation actuator assembly 26 after loading is located on the transport line, and the magnetic levitation actuator assembly 26 after unloading is located on the return transport line 28.

[0082] Understandably, the magnetic levitation actuator assembly 26 after loading refers to the magnetic levitation actuator assembly 26 carrying the target core 18, while the magnetic levitation actuator assembly 26 after unloading refers to the magnetic levitation actuator assembly 26 without carrying the target core 18, i.e., an empty magnetic levitation actuator assembly 26. Throughout the entire transportation process, the number of magnetic levitation actuator assemblies 26 remains constant, and multiple magnetic levitation actuator assemblies 26 are continuously recycled.

[0083] In one embodiment, the return transport line 28 extends close to the output end 16b of the unloading transport line 16 and is configured to return the magnetic levitation actuator assembly 26, which is located at the output end 16b of the unloading transport line 16 and has been unloaded, to the loading transport line 16.

[0084] In some embodiments, the feeding conveyor line 15 and the return conveyor line 28 may be arranged in a closed loop, but are not limited thereto.

[0085] In other embodiments, the loading conveyor line 15 and the return conveyor line 28 can be stacked. In this case, the ends of the loading conveyor line 15 and the return conveyor line 28 can be dynamically connected by a vertically connected servo machine 23.

[0086] Understandably, the output terminals 16b of the return conveyor line 28 and the unloading conveyor line 16 can also be dynamically connected via the horizontal or vertical connection servo 23, but are not limited to this.

[0087] In this embodiment of the invention, the target core 18 at the output end of the feeding conveyor line is identified by the core identification mechanism 13 (e.g., color mark sensor 21), and the identified target core 18 is transferred to the corresponding sub-unloading conveyor line 17 by the core connection mechanism, thereby realizing automatic unloading of cores of different models from different sub-unloading conveyor lines 17. Since this embodiment of the invention can identify and sort cores of different models, different models of cores can be produced simultaneously on the production line, improving double-shift production to single-shift production, reducing labor and environmental costs, increasing equipment utilization, and reducing equipment energy consumption costs, thus contributing to lower product costs.

[0088] like Figure 7 As shown, this utility model embodiment also provides a core logistics system 30, which includes a storage warehouse 31 and a core transport device 10 as described in the foregoing embodiment. The storage warehouse 31 includes a plurality of sub-warehouses 32 that are arranged one-to-one with a plurality of sub-unloading transport lines 17. Each sub-warehouse 32 is located at the output end 16b of the corresponding sub-unloading transport line 17.

[0089] Understandably, each type of core has a corresponding sub-warehouse 32, and each core is unloaded into the corresponding sub-warehouse 32 for storage via the corresponding sub-unloading conveyor line 17.

[0090] In one specific embodiment, sub-warehouse 32 includes, but is not limited to, automated warehouses.

[0091] In this embodiment of the utility model, since the core conveying device 10 can automatically unload different types of cores from different sub-unloading conveying lines 17, it avoids different types of cores being unloaded into the same sub-warehouse 32, thereby avoiding the problem of mixing materials, which is conducive to improving production efficiency and avoiding safety problems caused by mixing materials.

[0092] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
