Description

Technical Field

[0001] This invention belongs to the field of lithium battery production technology, and more specifically, relates to an electrode roll three-dimensional buffer system and a transfer method. Background Technology

[0002] Currently, in lithium battery production, electrode roll buffer racks are fixedly distributed at the edge of the rolling mill's unloading area. These racks are numerous and independently located around the unloading area, requiring significant planar space, which poses a major challenge to centralized management of the electrode rolls. Existing distributed fixed buffer racks consist of two parts: an upper support base for the electrode rolls and a lower frame composed of four pillars. The base base is welded to the frame. Typically, a certain number of AGVs (Automated Guided Vehicles) are used for transporting the electrode rolls, achieving fixed buffering. The AGV docking space requirement is large, necessitating careful planning of the number of AGVs and their path space based on the number of electrode roll buffer racks. With the surge in demand for new energy sources and the continuous increase in lithium battery factory capacity, the limited factory space cannot meet the buffering requirements of flat, fixed buffer devices. Furthermore, the frequent alternation between rolling mills in different environmental zones and the cutting area via lifting doors is detrimental to environmental control and inevitably leads to electrode roll contamination, affecting the quality of the finished batteries. Summary of the Invention

[0003] The purpose of this invention is to address the above shortcomings by providing a three-dimensional buffer system and transfer method for polar rolls. By buffering polar rolls in a three-dimensional library format, the AGV only needs to connect to one loading port and one unloading port, which can greatly reduce the AGV's operating space and improve its operating efficiency. The three-dimensional library buffer design makes full use of three-dimensional space, reduces the planar space for polar roll buffering, and facilitates centralized environmental management of polar rolls.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a three-dimensional buffer system for extreme rolls, including a partition wall disposed between a cutting area and a roll section, wherein a rectangular corridor is provided in the partition wall; The rectangular corridor is equipped with a cache channel, which contains a stacker crane. On both sides of the cache channel are three-dimensional vertical scroll cache warehouses. The buffer channel is equipped with conveyor lines for loading and unloading electrode rolls at both ends, and double-door interlocking devices are installed at the points where the conveyor lines pass through the rectangular corridor. In the above technical solution, by setting up a partition wall with a rectangular corridor between the cutting area and the rolling area, the two working areas are physically isolated, effectively preventing cross-contamination of dust and improving the production yield of electrode rolls; by using the conveyor line to connect the two areas and equipping it with a three-dimensional buffer warehouse, the automated transfer and storage of electrode rolls is realized, and the relative enclosure of the two areas is improved; by using the three-dimensional buffer warehouse and stacker crane in the rectangular corridor, high-density storage of electrode rolls in vertical space is achieved, which greatly saves the factory floor space and improves the site utilization rate; at the same time, the application of the stacker crane enables the electrode rolls to be efficiently stored and retrieved between the warehouse and the conveyor line, providing a stable buffer for continuous production and reducing waiting and congestion between production links. The double-door interlock device, also known as the AB door, is a safety device that uses mechanical or electronic control to lock two doors together. Its core mechanism is that when door A is open, door B is locked, and vice versa, thus ensuring that the two doors cannot be opened at the same time. The double-door interlock device at both ends of the conveyor line ensures that the pressure difference between the areas can be maintained when materials enter and exit the clean area, eliminating the risk of contamination caused by direct airflow.

[0005] Furthermore, the conveyor line is a roller conveyor line.

[0006] In the above technical solution, a roller conveyor is used as the conveyor line. Its simple structure and high load-bearing capacity make it ideal for carrying heavy electrode coils, ensuring the stability and reliability of material conveying. The roller conveyor can achieve continuous and stable transmission, and can efficiently connect with loading and unloading ports and stacker cranes, improving the overall material flow efficiency of the system. Furthermore, the roller conveyor has low maintenance costs, is easy to clean, and meets the cleanliness requirements of lithium battery production workshops.

[0007] Furthermore, the polar roll cache storage unit is a three-dimensional rack, preferably a beam-type automated three-dimensional rack.

[0008] In the above technical solution, the racking system provides a wide field of vision, facilitating precise access by stacker cranes and improving the efficiency and accuracy of inbound and outbound operations. The length and height can be customized according to the specifications and weight of the rolls, as well as buffer requirements and the height of the factory, offering strong adaptability. The use of beam-type automated storage and retrieval systems is robust and flexible in assembly. Combined with automated equipment, it enables digital management of roll storage, making inventory information more transparent and inventory checks more convenient.

[0009] Furthermore, the caching system also includes a polar roll caching fixture capable of caching and transporting multiple polar rolls at once; both ends of the caching channel are also equipped with conveyor lines for transporting the polar roll caching fixture. The capacity of the fixture can be set according to the size of the vertical storage unit and the frequency of polar roll usage. Preferably, this invention is configured such that one polar roll caching fixture can cache three polar rolls at a time.

[0010] In the above technical solution, the tooling design that can buffer and transfer multiple electrode rolls at once significantly improves the efficiency of single handling and reduces the frequency of round trips of conveyor equipment. Its capacity can be flexibly set according to the size of the vertical storage unit and the frequency of electrode roll usage, enhancing the adaptability of the system configuration. The preferred configuration is to buffer three electrode rolls at a time, balancing load capacity and operational convenience, which is conducive to batch operations. Through dedicated conveyor lines for transferring electrode roll buffering tooling set at both ends of the buffer channel, empty tooling can be promptly returned upstream or entered into the vertical storage unit, ensuring the continuity of tooling supply and avoiding production interruptions due to a shortage of empty tooling. Tooling can quickly circulate between the buffer area and the work area, forming an efficient logistics cycle. This batch processing mode not only optimizes the production cycle but also reduces energy consumption and wear caused by frequent equipment start-ups and shutdowns. This design improves the closed-loop management of material carriers and enhances the overall logistics efficiency of the system.

[0011] Furthermore, the conveyor line for loading and unloading the electrode rolls has an electrode roll loading port on one side of the roller section and an electrode roll unloading port on the other side of the cutting section. The conveyor line used for transferring the electrode coil buffer tooling has an empty disc unloading port on one side of the roller section and an empty disc loading port on the other side of the coil cutting section.

[0012] In the above technical solution, by setting up electrode roll loading ports and empty reel unloading ports in the roller zone, and electrode roll unloading ports and empty reel loading ports in the cutting zone, a clear material flow and tooling return path is formed, avoiding material flow line intersections and congestion. This zoned setup ensures that the loading and unloading of electrode rolls and the return of empty reels do not interfere with each other, with clear logic, facilitating scheduling and management by the automated control system. Clear physical interfaces make the connection between upstream and downstream processes smoother, improving the flexibility of production organization.

[0013] Furthermore, the roller section includes a positive roller section and a negative roller section, and the conveyor line is provided with a roller feed port and an empty reel discharge port at both ends corresponding to the positive roller section and the negative roller section; each roller feed port and empty reel discharge port is provided on the other side of the conveyor line.

[0014] In the above technical solution, the positive electrode roller section and the negative electrode roller section are respectively equipped with electrode roll loading port and empty tray unloading port, realizing independent conveying and management of positive and negative electrode materials. This design effectively avoids the risk of confusion between electrode rolls of different polarities on the conveyor line and meets the requirements for strict material separation in battery production. At the same time, the dual-line design also improves the system's parallel processing capability.

[0015] Furthermore, the electrode roll tooling includes a tray base, on which a plurality of partitions are provided. The upper end of the partitions is provided with grooves for supporting the electrode roll shaft. A plurality of electrode rolls are sleeved on the electrode roll shaft, and adjacent electrode rolls are separated by the partitions.

[0016] In the above technical solution, the base is designed in the form of a pallet, suitable for various applications such as AGV handling, conveyor line transport, and stacker crane handling. The pallet base is equipped with grooved partitions, providing stable support and positioning for the electrode rolls and preventing them from rolling or shifting during transport. The partitions separate adjacent electrode rolls, effectively avoiding collisions and friction between them, protecting the surface quality and structural integrity of the electrode rolls. This design is particularly suitable for multi-layer stacked buffers, ensuring the security of three-dimensional storage.

[0017] Furthermore, an anti-collision mechanism is installed on the tray base of the polar roll buffer fixture. The anti-collision mechanism includes a screw, a spring, and a pad. One end of the spring is connected to the nut of the screw, and the other end is connected to the pad. The screw is installed in a threaded hole in the tray base, and the threaded hole is arranged on both sides of the tray base in the running direction.

[0018] In the above technical solution, by installing an anti-collision mechanism, lateral impact forces can be effectively absorbed and buffered during tooling movement or stacker crane operation, protecting the tooling body and its electrode coils from damage. The elastic buffer provided by the spring can accommodate a certain positioning error, reducing the stringent requirements for the alignment accuracy of automated equipment. This mechanism is ingenious in structure and low in cost, yet significantly improves the safety and stability of system operation.

[0019] Furthermore, it also includes a conveying device for transporting pole rolls and pole roll buffers in the roll section and the cutting section, wherein the conveying device is preferably an AGV.

[0020] In the above technical solution, the conveying equipment transports the coils and buffer fixtures between the roller sections and the cutting section, greatly improving the system's flexibility and automation level. Using AGVs allows for flexible path planning based on scheduling instructions, achieving precise material docking and reducing the rigid limitations of fixed conveyor lines; at the same time, it reduces the labor intensity and error rate of manual handling, making the entire logistics process more intelligent and efficient.

[0021] Secondly, the present invention provides a polar roll transfer method, based on the polar roll three-dimensional caching system described in the first aspect, comprising: When the roller section is unloaded, the polar rolls in the roller section are transferred to the conveyor line for unloading polar rolls through the polar roll loading port. The conveyor line transports the polar rolls to the handling position of the stacker crane. The stacker crane then transports the polar rolls to the polar roll buffer warehouse for buffering. When loading materials into the cutting and rolling area, the electrode rolls placed on the electrode roll buffer warehouse are transported by a stacker crane to the conveyor line used for electrode roll loading and unloading. The electrode rolls are then transported to the electrode roll unloading port through the conveyor line and enter the cutting and rolling area through the electrode roll unloading port.

[0022] In the above technical solution, the method, based on the aforementioned system, provides a complete standardized operating procedure, clearly defining the bidirectional material flow path between the rolling zone unloading and the cutting zone loading. Through the coordinated operation of conveyor line transport, stacker crane storage and retrieval, and vertical storage silo buffering, the orderly and automated transfer and buffering of electrode coils between key processes is achieved, ensuring the standardization and efficiency of electrode coil flow. The coordinated operation of the stacker crane and conveyor line completely replaces manual handling, significantly improving production efficiency. Utilizing the buffer silo as a buffer node effectively solves the problem of wasted capacity caused by inconsistent production cycles between upstream and downstream processes, allowing the rolling and cutting processes to operate continuously. This method has a clear process flow, avoiding chaos and congestion during cross-zone material flow and ensuring the orderly scheduling of production.

[0023] Furthermore, the transfer method also includes placing the polar roll in a polar roll buffer fixture during the polar roll transfer process. When the electrode rolls placed in the electrode roll buffer fixture are used up, the empty electrode roll buffer fixture is transferred through the empty tray loading port to the conveyor line used for electrode roll buffer fixture transfer. If the roller section requires an empty electrode roll buffer fixture, the empty electrode roll buffer fixture is directly transported to the empty tray unloading port via a conveyor line; if the empty electrode roll buffer fixture needs to be buffered, the empty electrode roll buffer fixture is transported to the electrode roll buffer vertical storage via a stacker crane.

[0024] The above technical solution introduces a return and buffer management mechanism for empty buffer fixtures based on the electrode roll transfer system. Depending on demand, empty fixtures can be directly returned to the roll section or temporarily stored in an automated storage and retrieval system, forming a complete cycle for the electrode roll buffer fixtures. When the electrode rolls are consumed, the system can automatically recycle the empty fixtures and buffer them in the automated storage and retrieval system or send them directly back to the demand side, achieving separate management of filled materials and empty containers. This containerized transfer mode not only protects the safety of the electrode rolls during the transfer process but also ensures that the material flow and the fixture flow do not interfere with each other, further improving the operational efficiency and intelligence level of the entire logistics system.

[0025] Furthermore, in both the roll section and the cutting section, AGVs are used to transport the pole rolls and pole roll buffers between the loading and unloading ports and between the roll sectioning equipment and the cutting equipment.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: Compared with traditional distributed and fixed flat-layout electrode roll buffer racks, the electrode roll three-dimensional buffer system and method disclosed in this invention makes full use of three-dimensional space, which can greatly save flat space. Compared with the distributed flat-layout electrode roll buffer rack method, this system eliminates the lifting door, and the whole is in a relatively closed space, which is suitable for frequent alternation of operations, and will not affect the environmental control of the two areas, and also greatly protects the electrode roll from being contaminated. Compared with traditional fixed polar roll buffer devices, the three-dimensional buffer storage of the present invention can greatly reduce the coverage area and conveying space of AGVs. The present invention only requires AGVs to deliver the polar rolls or polar roll buffer fixtures to the loading port of the connecting conveyor line, reducing the number of AGVs required. The AGV conveying path is simple and clear, which greatly improves the efficiency of AGVs and has a higher economic effect. This invention also discloses a matching dedicated electrode roll buffer fixture, which can store multiple electrode rolls simultaneously and is flexibly applicable to scenarios such as AGV conveying, conveyor line conveying, and stacker crane handling. This dedicated fixture is also equipped with an anti-collision device, which greatly protects the electrode rolls and prevents them from being damaged by collisions during transport on the conveyor line.

[0029] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings and specific examples.

[0030] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0031] Unless the context requires otherwise, throughout the specification and claims, the word “comprising” and its variations, such as “including” and “having”, shall be understood to have an open, inclusive meaning, that is, to be interpreted as “including, but not limited to”.

[0032] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0033] The singular forms “a” and “the” used in this specification and the appended claims include plural references unless otherwise expressly stated herein. It should be noted that the term “or” is generally used to mean “and / or” unless otherwise expressly stated herein.

[0034] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] Traditional high-volume cache devices such as Figure 1 As shown, the system includes partition walls, lifting doors (1800mm x 2400mm), and flat, fixed buffer racks. Strict environmental controls are in place during lithium battery production. The rolling zone and the slitting zone are two separate environmental control areas, separated by partition walls. Electrode rolls from the rolling zone are laid flat along the wall for buffering. Each of the positive and negative electrode areas has a lifting door for AGVs to transport electrode rolls from the rolling zone buffer racks to the slitting machine, and for AGVs to transport empty electrode rolls to the rolling zone buffer racks. Frequent operation, with the lifting doors constantly rising and falling, disrupts the controlled environment and affects battery quality. The electrode rolls are laid flat on the exposed buffer racks; the operation of workshop equipment, AGVs, and personnel movement all increase contamination of the electrode rolls, impacting battery quality.

[0036] Example 1 like Figure 2As shown, this embodiment provides a three-dimensional polar roll buffer system, including a partition wall disposed between the cutting area 11 and the roller section 12; a rectangular corridor 15 is provided in the partition wall; a buffer channel 14 is provided in the rectangular corridor 15, and three-dimensional polar roll buffer storage 2 is provided on both sides of the buffer channel 14; a roller line 1 is provided at each end of the buffer channel 14 as a conveyor line for loading and unloading polar rolls 10, and AB doors 13 are provided at the positions where the roller lines 1 pass through the rectangular corridor 15; a stacker crane 3 is provided in the buffer channel 14 for transporting polar rolls 10 between the roller lines 1 and the polar roll buffer storage 2.

[0037] The roller section 12 includes a positive roller section and a negative roller section. The roller line 1 is provided with a roller feed port 4 at both ends corresponding to the positive roller section and the negative roller section. Each roller feed port 4 is provided with a roller unloading port 5 on one side of the cutting and winding area 11 of the roller line 1.

[0038] like Figure 3 As shown, the polar roll cache storage unit 2 described in this embodiment is a beam-type automated three-dimensional rack, mainly composed of: rack panels, bracket beams, horizontal tie rods, vertical tie rods, ceiling rail beams, ceiling rail end frames, ceiling rails, etc. It is assembled in a modular manner, and the rack material is made of high-quality steel.

[0039] In this embodiment, AB gate 13 is as follows: Figure 4 As shown, the AB door, also known as a double-door interlock, is a safety device that uses mechanical or electronic control to achieve interlocking locking of two doors. Its core mechanism is that when door A is open, door B is locked, and vice versa, ensuring that the two doors cannot be opened simultaneously. In actual production, standard parts of the corresponding specifications can be directly purchased. Installing AB door 13 at the wall penetration point of roller line 1 ensures that the pressure difference between areas is maintained stable when materials enter and exit the clean area, eliminating the risk of contamination from direct airflow.

[0040] In this embodiment, the pole roll 10 is transported between the roller slitting equipment and the roller cutting equipment in the roller section 12 and the cutting section 11 by an AGV and the roller line 1.

[0041] The polar roll three-dimensional caching system described in this embodiment is highly suitable for high-efficiency operations. The polar roll 10 can complete frequent outbound and inbound alternations through this system without affecting the control of two different environmental zones. The polar roll 10 is always cached in a relatively enclosed space, effectively protecting it from external environmental contamination.

[0042] Example 2 This embodiment provides a polar-volume 3D caching system, which further refines the technical solution based on Embodiment 1 to provide better technical effects. Parts not described in detail in this embodiment refer to Embodiment 1 and will not be repeated here.

[0043] This embodiment also includes a matching dedicated polar-volume cache fixture 8; such as Figure 5 As shown, the electrode roll buffer fixture 8 can buffer three electrode rolls 10 at a time. Its structure includes a tray base 81, on which four partitions 82 are provided. The upper end of each partition 82 has a groove for supporting an electrode roll shaft 83. Three electrode rolls 10 are fitted onto the electrode roll shaft 83, with adjacent electrode rolls 10 separated by the partitions 82. In this embodiment, the conveying and transfer of the electrode rolls 10 are both carried out within the electrode roll buffer fixture 8. Figure 6 A schematic diagram showing the state of the electrode roll buffer fixture 8, which is loaded with electrode roll 10, being conveyed on the roller line 1.

[0044] In this embodiment, in addition to the roller line 1 for loading and unloading the electrode rolls 10, the buffer channel 14 is also equipped with a roller line 1 at both ends as a conveyor line for transferring the electrode roll buffer fixture 8. AB doors 13 are also provided at the positions where the roller line 1 passes through the rectangular corridor 15. Empty disc unloading ports 7 are provided at both ends of the roller line 1 corresponding to the positive and negative electrode roll sections; each empty disc unloading port 7 is provided with an empty disc loading port 6 on one side of the cutting area 11 of the roller line 1.

[0045] In this embodiment, several anti-collision mechanisms 9 are installed on both sides of the tray base 81 of the polar roll buffer fixture 8 along the running direction of the roller, such as... Figure 7 As shown, the anti-collision mechanism 9 includes a screw 91, a spring 92, and a rubber pad 93. One end of the spring 92 is attached to the nut of the screw 91, and the other end is attached to the rubber pad 93. The screw 91 is installed in a threaded hole in the pallet base 81, and the threaded hole is arranged on both sides of the pallet base 81 in the running direction. By installing the anti-collision mechanism 9, collisions can be effectively prevented between the electrode roll buffer fixture 8 and the roller during operation, thus preventing damage to the electrode roll.

[0046] Example 3 This embodiment provides a polar roll transfer method based on the polar roll three-dimensional caching system described in Embodiment 1 or Embodiment 2. The method specifically includes the following steps: After the electrode rolls 10 are unloaded from the positive and negative electrode roller sorting equipment, they are placed on the electrode roll buffer fixture 8 by an AGV. Then, the AGV transfers the electrode roll buffer fixture 8 containing the electrode rolls 10 to the roller line 1 through the electrode roll loading port 4 of the corresponding area. The roller line 1 transports the electrode roll buffer fixture 8 containing the electrode rolls 10 to the handling position of the stacker crane 3. The stacker crane 3 transports the electrode roll buffer fixture 8 containing the electrode rolls 10 to the electrode roll buffer vertical storage 2 for buffering. For systems without electrode roll buffer fixture 8, the AGV, roller line 1, and stacker crane 3 directly handle or transport the electrode rolls 10, and the electrode rolls 10 are directly placed in the electrode roll buffer vertical storage 2. The following steps are the same. When the cutting and rolling equipment needs to feed the polar roll 10, the stacker crane 3 transports the polar roll buffer fixture 8 placed on the polar roll buffer warehouse 2 to the roller line 1. The roller line 1 then transports the polar roll buffer fixture 8 containing the polar roll 10 to the corresponding polar roll unloading port 5. The AGV then removes the polar roll buffer fixture 8 containing the polar roll 10 from the polar roll unloading port 5.

[0047] When the electrode rolls 10 placed on the electrode roll buffer fixture 8 are used up, the AGV will transport the empty electrode roll buffer fixture 8 to the empty tray loading port 6 of the corresponding area. If the roller separator needs an empty electrode roll buffer fixture 8, the empty electrode roll buffer fixture 8 will be directly transported to the corresponding empty tray unloading port 7 through the roller conveyor 1. The AGV will then take the empty electrode roll buffer fixture 8 for use by the roller separator equipment. If the empty electrode roll buffer fixture 8 needs to be buffered temporarily, the stacker crane 3 will transport the empty electrode roll buffer fixture 8 to the electrode roll buffer vertical storage 2 for buffering.

[0048] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and principles of the described embodiments, and these modifications and variations should also be considered within the scope of protection of the present invention.
