Description

Technical Field

[0001] The present invention relates to the technical field of logistics line optimization scheduling, and in particular to an intelligent scheduling optimization method for alleviating the waiting of AB roll cores for roll cutting and assembly. Background Art

[0002] Cutting and assembly is the core process of lithium battery production, and also the pre-bottle process of lithium battery production. Improving the overall efficiency of equipment and increasing production capacity are the key tasks of cutting and assembly. Cutting mainly includes laser cutting and winding. Laser cutting mainly uses laser to cut the positive and negative electrode coils and cut out the pole ears; winding mainly winds the positive and negative electrode coils and the diaphragm together into a core. According to the different winding methods, all cores include two types: A core and B core (the positive electrode of A core corresponds to the positive electrode of B core, and the negative electrode of A core corresponds to the negative electrode of B core). Each cutting and assembly equipment corresponds to one of the winding methods. In the actual production line layout, AB cutting and assembly machines are arranged in an interlaced manner. On the production line, a group of A cores match a group of B cores and enter the next process assembly at the same time before production can be carried out. If the same group of logistics lines lacks A cores or B cores, the assembly will be waiting for materials, causing the equipment to stop. At the same time, the cores to be matched are piled up on the logistics line to block the material, causing this type of cutting and assembly machine on this line to stop. Different groups of logistics lines exist independently and do not affect each other before flowing into assembly, which may lead to excessive buffering of roll cores on one side and material blockage, while the roll cores on the other side of the logistics line may be insufficient and waiting for materials. At present, the production line uses manual transfer of pallet roll cores to other logistics lines or unloading, which is labor-intensive and cannot be handled in time, causing the coil cutting machine equipment to shut down, the overall efficiency of the equipment is low, which has a great impact on the production capacity of the entire line and increases the manufacturing cost. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art. To achieve the above purpose, an intelligent scheduling optimization method for alleviating the waiting time for AB core material in roll cutting and assembly is adopted to solve the problems raised in the above background technology.

[0004] An intelligent scheduling optimization method for alleviating the waiting of AB cores for cutting and assembling rolls, comprising the following steps:

[0005] Step S1, the cells produced by different groups of slitting machines are transported to each group of logistics lines respectively, and after each group of AB cores is matched, they are processed by each group of assembly process machines at the back end of the current logistics line;

[0006] Step S2, when the reeling machine of each group of logistics lines stops, the elevator assembly is used to transport the fully loaded core pallet of the current logistics line through the elevated logistics line to the waiting line of other groups of logistics lines for AB core matching and further processing. The flexibility and efficiency of the production line are improved by processing the battery cells of different reels by grouping logistics lines. The matching of AB cores ensures the pairing accuracy of the battery cells and provides a stable quality foundation for subsequent assembly processes. The problem of production interruption caused by the shutdown of the reeling machine is solved, and the reliability and continuity of the production line are improved. The elevator assembly is used to achieve rapid scheduling of fully loaded core pallets, reducing production waiting time.

[0007] As a further solution of the present invention: the specific steps in step S1 include:

[0008] The battery cells produced by the three groups of coil cutting machines are respectively transported to each group of logistics lines, wherein the logistics lines include a first logistics line, a second logistics line, and a third logistics line;

[0009] If the slitting machines of the AB cores on each group of logistics lines operate normally, a group of A cores and a group of B cores in the first logistics line, the second logistics line, and the third logistics line are matched;

[0010] After each set of AB cores are matched, they will be processed again by each set of assembly process machines at the back end of the current logistics line. The specific configuration of the logistics line and the cell matching process are clarified, providing clear guidance for actual operation. The parallel processing of three sets of coil cutting machines further improves the production line's capacity and efficiency.

[0011] As a further solution of the present invention: the specific steps in step S2 include:

[0012] When any group of A or B core slitting machines stops, and other slitting machines in the current logistics line are unloading full pallets, the full pallets of the other group of A or B cores will be assembled and transported to the rear end of the logistics line;

[0013] When pallets are piled up, the rear elevator component recognizes that there are full pallets waiting on the rear logistics line, and then the elevator starts to lift the full roll core pallet located on the elevator component station to the fifth logistics cache line, and transports it to other logistics lines in a counterclockwise direction on the fifth logistics cache line; and the elevator components corresponding to other groups of logistics lines recognize whether there are full pallets waiting for the roll core on the rear end, and determine whether there is a need to unload materials;

[0014] If there is a need to unload materials, the elevator assembly starts and the fully loaded coil core pallet moves down for transportation;

[0015] If there is no unloading demand, the fully loaded coil core pallet is released and continues to be transported counterclockwise to other logistics lines on the fifth and sixth logistics cache lines;

[0016] Until the fifth and sixth logistics cache lines cache the cores to each group of logistics lines through the elevator assembly, matching the other side of the core. Through the intelligent scheduling of the elevator assembly, the full pallet is quickly transferred between different logistics lines, improving the flexibility and adaptability of the production line. It solves the production bottleneck problem caused by pallet accumulation and ensures the smooth operation of the production line.

[0017] As a further solution of the present invention, the elevator assembly can identify in each group of logistics lines that there are fully loaded core pallets waiting for the logistics line for rear-end delivery assembly, and can transport the A core or B core upward or downward in case of material blockage. The intelligence level of the elevator assembly is improved, so that it can be flexibly dispatched according to the actual situation of the production line, solve the material blockage problem, and ensure the stable operation of the production line.

[0018] As a further solution of the present invention: the fifth logistics cache line and the sixth logistics cache line form a closed-loop reflux that can cache fully loaded coil core pallets, and intersect with the logistics lines for unloading materials from multiple coil cutting devices, and realize the upward and downward transportation of coil core pallets through elevators. Through the setting of the logistics cache line, effective caching and scheduling of fully loaded pallets are achieved, and the storage and scheduling capabilities of the production line are improved. The setting of the closed-loop reflux ensures the recycling of pallets and reduces resource waste.

[0019] As a further solution of the present invention: the fifth logistics cache line and the sixth logistics cache line form a closed loop reflux, and cooperate with the elevator assembly to transport the core pallet in a counterclockwise or clockwise direction. The coordination mode between the logistics cache line and the elevator assembly is clarified, providing clear guidance for actual operation. By specifying the conveying direction, the orderly flow of pallets between logistics lines is ensured.

[0020] As a further solution of the present invention: determining the priority of the elevator, and determining the priority of the material-blocked logistics line being transported upward and the priority of the material-deficient logistics line being transported downward by the logistics buffer line;

[0021] When smart scheduling is turned on, only one of the core pallets scheduled at the same time is core A or core B. By setting priorities, the scheduling efficiency and fairness of the production line are ensured. The production chaos caused by improper scheduling is solved, and the stability and controllability of the production line are improved.

[0022] As a further solution of the present invention: when multiple groups of different coil cutting machines are arranged in parallel lines along the flow line direction of the logistics line, and the fifth logistics buffer line and the sixth logistics buffer line above the logistics line are extended according to actual requirements;

[0023] The fifth and sixth logistics cache lines and the logistics lines below convey the core pallets through the elevator assembly to optimize the deployment between multiple groups of logistics lines. The parallel line layout and the extension of the logistics cache lines improve the scalability and flexibility of the production line. It adapts to the changes in different production scales and needs, and provides a strong guarantee for the long-term stable operation of the production line.

[0024] Compared with the prior art, the present invention has the following technical effects:

[0025] By adopting the above-mentioned technical solution, the battery cells produced by different reeling machines are grouped and transported to their corresponding logistics lines through step S1, and after the AB cores are matched, they are reprocessed by the assembly process machine at the back end of the logistics line, thereby realizing the orderly production and efficient assembly of the battery cells. In step S2, in view of the possible shutdown of the reeling machine on the logistics line, a solution is designed to use a lift assembly to quickly transfer the fully loaded core pallet to other logistics lines through the elevated logistics line to ensure the continuous matching and processing of the battery cells and avoid production interruptions. It not only improves the automation and efficiency of battery cell production and ensures the continuous and stable operation of the production line, but also effectively responds to the production challenges brought about by equipment failures. By flexibly scheduling fully loaded pallets, it minimizes production waiting time and improves the reliability and flexibility of the overall production line. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please refer to Figure 1 and Figure 2 In an embodiment of the present invention, an intelligent scheduling optimization method for alleviating the waiting time of AB cores for cutting and assembling rolls includes the following steps:

[0034] Step S1: The cells produced by different groups of slitting and winding machines 4 are respectively delivered to each group of logistics lines, and after each group of AB winding cores are matched, they are processed by each group of assembly process machines at the back end of the current logistics line. The specific steps include:

[0035] The cells produced by the three groups of coil cutting machines 4 are respectively transported to the respective groups of logistics lines, wherein the logistics lines include a first logistics line 1, a second logistics line 2, and a third logistics line 3;

[0036] If the coil cutting machine 4 of the AB cores on each group of logistics lines operates normally, a group of A cores and a group of B cores in the first logistics line 1, the second logistics line 2, and the third logistics line 3 are matched;

[0037] After each set of AB cores is matched, it will be further processed by each set of assembly process machines at the back end of the current logistics line.

[0038] In this embodiment, Figure 3 As shown in the figure; the three groups of coil cutting machines 4 produce battery cells and transport them to the first logistics line 1, the second logistics line 2, and the third logistics line 3 of their respective logistics lines. If the AB coil cutting machines 4 on each group of logistics lines operate normally, then each AB coil core can be matched and assembled by the machines of each process at the back end of the line for further processing; if a coil cutting equipment stops working, it will be resolved in the subsequent step S2.

[0039] Step S2: When the coil cutting machine 4 of each group of logistics lines stops, the fully loaded coil core tray 8 of the current logistics line is transported to the material waiting line of other groups of logistics lines through the elevated logistics line for AB coil core matching and further processing. The specific steps include:

[0040] like Figure 4 As shown, the figure is a schematic diagram of the transportation direction of the scheduling logistics line;

[0041] When any group of A core or B core cutting machine 4 stops, and other cutting machines 4 of the current logistics line are unloading full pallets, the full pallets of the other group of A core or B core are assembled and transported to the rear end on the logistics line;

[0042] When the pallets are piled up, the rear elevator component recognizes that there are full pallets waiting on the rear logistics line, and then the elevator starts to lift the full roll core pallet 8 located on the elevator component station to the fifth logistics cache line 5, and transports it to other logistics lines in a counterclockwise direction on the fifth logistics cache line 5; and the elevator components corresponding to other groups of logistics lines recognize whether there are full pallets waiting for the roll core at the rear end, and determine whether there is a need to unload materials;

[0043] If there is a need to unload materials, the elevator assembly is started, and the fully loaded coil core tray 8 is moved down for transportation;

[0044] If there is no unloading demand, the fully loaded coil core tray 8 is released and continues to be transported to other logistics lines in a counterclockwise direction on the fifth logistics cache line 5 and the sixth logistics cache line 6;

[0045] Until the fifth logistics cache line 5 and the sixth logistics cache line 6 cache the core rolls through the bottom of the elevator assembly to each group of logistics lines to match the other side of the core rolls.

[0046] In this embodiment, if the coil cutting machine 4 of a certain (A side or B side) coil core in the first logistics line 1 stops, the other coil cutting machines 4 in the line unload materials with full pallets. According to the rhythm operation logic, the shutdown causes the efficiency of this line to be lower than that of the other side. The coil cutting machine 4 on the other side continues to produce coil cores that are piled up on the logistics line to block the material. The first elevator 9 at the rear end of the first logistics line 1 recognizes that there is a full pallet waiting on the rear logistics line, and the first elevator 9 starts to lift the full coil core pallet 8 on the elevator station to the fifth logistics cache line 5, and the full coil core pallet 8 is transported along the fifth logistics cache line 5 to the second logistics line 2.

[0047] The second elevator 10 identifies whether there is a full pallet waiting for the roll core at the rear end of the second logistics line 2, and determines whether there is a need to unload the material;

[0048] If there is a need to unload materials, the second elevator 10 is started, the pneumatic barrier is raised, and the fully loaded core tray 8 on the fifth logistics buffer line 5 is moved down and transported to the second logistics line 2 logistics line, and the matching core on the other side is transported to the assembly;

[0049] If there is no unloading demand, the pneumatic barrier is released, and the fully loaded coil core tray 8 is released and transported along the fifth logistics buffer line 5 to the third logistics line 3;

[0050] The third elevator 11 identifies whether there is a full pallet waiting for the roll core at the rear end of the third logistics line 3, and determines whether there is a need to unload the material;

[0051] If there is a need to unload materials, the third elevator 11 is started, the pneumatic barrier is raised, and the fully loaded core tray 8 on the fifth logistics buffer line 5 is moved down and transported to the third logistics line 3 logistics line, and the matching core on the other side is transported to the assembly;

[0052] If there is no need to unload materials, the pneumatic barrier is released, and the fully loaded coil core tray 8 is released and transported to the sixth logistics buffer line 6;

[0053] The fully loaded roll core pallet 8 passes through the fourth elevator, and the fourth elevator identifies whether there is a fully loaded pallet waiting for the roll core at the rear end of the first logistics line 1, and determines whether there is a need for unloading;

[0054] If there is a need to unload materials, the fourth elevator is started, the pneumatic barrier is raised, and the fully loaded core tray 8 on the sixth logistics buffer line 6 is moved down and transported to the first logistics line 1 logistics line, and the matching core on the other side is transported to the assembly;

[0055] If there is no need to unload materials, the pneumatic barrier is released, and the fully loaded coil core tray 8 is released and transported along the fifth logistics buffer line 5 via the first elevator 9;

[0056] Until the fifth logistics cache line 5 and the sixth logistics cache line 6 cache the roll core through the bottom of the elevator to each group of logistics lines to match the other side of the roll core.

[0057] In this embodiment, the elevator assembly can identify that the logistics line for rear-end delivery assembly has a fully loaded core pallet 8 waiting in each group of logistics lines, and can transport the A core or B core in the case of material blocking by ascending and descending. The fifth logistics cache line 5 and the sixth logistics cache line 6 form a closed-loop reflux that can cache the fully loaded core pallet 8, and intersect with the logistics lines for unloading of multiple coil cutting equipment, and realize the ascending and descending transportation of the core pallet through the elevator.

[0058] In this embodiment, the fifth logistics cache line 5 and the sixth logistics cache line 6 form a closed-loop reflux and cooperate with the elevator assembly to transport the core pallet in a counterclockwise or clockwise direction.

[0059] In this embodiment, the priority of the elevator is determined, as well as the priority of the logistics line with blocked materials being transported upward and the priority of the logistics line with insufficient materials being transported downward by the logistics buffer line;

[0060] When smart scheduling is turned on, there is only one type of core tray scheduled at the same time, either core A or core B.

[0061] In this embodiment, when multiple groups of different coil cutting machines 4 are arranged in parallel lines along the flow line direction of the logistics line, and the fifth logistics cache line 5 and the sixth logistics cache line 6 above the logistics line are extended according to actual requirements;

[0062] The fifth logistics cache line 5 and the sixth logistics cache line 6 transport the core pallets to the logistics lines below through the elevator assembly to optimize the deployment between multiple groups of logistics lines.

[0063] Specifically, it can be realized in three groups of coil cutting logistics lines, but the application implementation is not limited to this. When multiple groups of coil cutting equipment are arranged in parallel lines along the assembly line, the fifth logistics cache line 5 and the sixth logistics cache line 6 above are appropriately extended, and the fifth logistics cache line 5 and the logistics line below use an elevator structure to transport the coil core pallets, thereby realizing intelligent allocation and optimization between multiple groups of logistics lines.

[0064] In this embodiment, the pneumatic blocking can be a telescopic cylinder driving the up and down movement of the baffle to achieve blocking of the moving fully loaded core pallet 8, so that the fully loaded core pallet 8 can choose to flow into the elevator station and move up or down for transportation or continue to move forward.

[0065] The elevators on the logistics line can all adopt the same structure and be driven by cylinders, but the operation of the elevators at each position is independent of each other, which can realize transfer and cross-line transportation, and can realize transfer in different directions or between different lines through direct settings.

[0066] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents, and all should be included within the scope of protection of the present invention.
