[0030] To better understand the spirit of the embodiments of this application, the following description is based on some preferred embodiments of this application.

[0031] Embodiments of this application will be described in detail below. Throughout this specification, identical or similar components and components having identical or similar functions are indicated by similar reference numerals. The embodiments described herein with reference to the accompanying drawings are illustrative and diagrammatic in nature and are intended to provide a basic understanding of this application. The embodiments of this application should not be construed as limiting this application.

[0032] As used herein, the terms “approximately,” “generally,” “substantially,” and “about” are used to describe and indicate minor variations. When used in conjunction with an event or situation, these terms may refer to examples in which the event or situation occurred precisely or in examples in which the event or situation occurred very approximately.

[0033] In this specification, unless otherwise specified or limited, relative terms such as “central,” “longitudinal,” “lateral,” “front,” “rear,” “right,” “left,” “inner,” “outer,” “lower,” “higher,” “horizontal,” “vertical,” “above,” “below,” “above,” “below,” “top,” “bottom,” and their derivatives (e.g., “horizontally,” “downward,” “upward,” etc.) should be interpreted as referring to the directions described in the discussion or depicted in the accompanying drawings. These relative terms are used for descriptive convenience only and do not require that this application be constructed or operated in a particular orientation.

[0034] For ease of description, "first," "second," "third," etc., can be used in this article to distinguish different components of a figure or a series of figures. "First," "second," "third," etc., are not intended to describe the corresponding components.

[0035] In the lithium battery production process, environmental control is implemented throughout the entire factory / workshop due to stringent requirements for temperature, humidity, and dust prevention (i.e., cleanliness). This stringent environmental control, applied to the entire workshop according to the highest standards, increases costs. However, the most crucial aspect is that environmental control requirements are only necessary for the specific environment of the equipment itself. Only a small portion of the equipment within the entire workshop may have high environmental requirements, making comprehensive environmental control for the entire workshop extremely costly. Controlling the entire factory / workshop environment is challenging and results in significant energy waste. Furthermore, if two production lines have different environmental control requirements, the equipment for those lines must be located in separate workshops, placing additional pressure on infrastructure.

[0036] On the other hand, existing technologies involve fragmented equipment distribution, leading to low efficiency and difficulty in management during equipment installation in newly built factories, especially when constructing overseas production lines. Production equipment must be transported from China to overseas for installation, commissioning, and assembly. Transporting equipment piecemeal overseas results in excessively long installation cycles, impacting production schedules. Commissioning work only begins after the production line is fully built, further extending the overall project timeline. Domestically, suppliers typically pre-assemble and debug the equipment before disassembling it into individual parts and transporting them to the factory for installation and debugging. If the same model is followed for overseas shipments, two problems arise. First, container shipping requires high-quality packaging, increasing transportation costs. Second, while domestic shipping allows for partial pre-assembly of equipment before delivery to the factory, transporting pre-assembled equipment overseas is cumbersome. Additionally, labor costs are a concern. Domestic shipping allows equipment manufacturers' employees to perform installation and commissioning at the factory, but overseas shipping may require hiring local professionals, resulting in higher labor costs. Therefore, it is desirable to debug some key processes domestically, allowing for simple assembly upon arrival overseas.

[0037] To meet the above requirements, the embodiments of this application integrate all the equipment originally arranged in a single workshop into separate zones. In the lithium battery production process, equipment that might otherwise be placed in a large space is modularly integrated into smaller areas, and each integrated module is subject to its own small-area zone management. Firstly, after the equipment is transported overseas, it can be quickly assembled without the need for disassembled parts, and some functions can be pre-tested before transportation, thus shortening the installation period. Secondly, environmental management costs can be reduced through zoned environmental management.

[0038] The aforementioned production equipment includes equipment for homogenization (mixing slurry evenly), coating (applying slurry to the electrode), drying, pre-slitting, rolling, slitting, die-cutting, winding / stacking, assembly, liquid injection, or chemical formation stages.

[0039] Existing technologies may install equipment on the workshop floor or walls. This application utilizes modular integration, integrating related or adjacent equipment onto the same support frame. If several pieces of equipment are simultaneously mounted on a single support frame, mechanical vibrations during operation can easily occur, potentially causing damage to adjacent equipment if resonance occurs. Therefore, vibration-damping pads are added at the connection points between vibrating equipment and the mounting frame. Alternatively, vibration-damping pads can be installed between precision equipment and the mounting frame, or the equipment can be connected to the mounting frame only during transport and then isolated during installation, directly mounted on the ground.

[0040] Figure 1 The diagram shows a factory building for a homogenization section of the prior art, in which the equipment is dispersed in powder workshop 1. Workshop 1 as a whole is controlled according to the highest environmental requirements [e.g., temperature is 15-28°C, humidity is ≤40% (negative), cleanliness is Class 10,000, and the floor treatment is epoxy thin coating].

[0041] Figure 2 The first area M of a battery production line 20 (for the homogenization section) according to the first embodiment of this application is shown, wherein the temperature is 15-28°C, the humidity is 40% (negative electrode), the cleanliness is Class 10,000, and the ground treatment is epoxy thin coating. Figure 3 The second area O of the battery production line 20 according to the first embodiment of this application is shown, wherein the temperature is 15-28°C, humidity is not required, cleanliness is 5S required, and the ground treatment is epoxy thin coating.

[0042] See Figure 2 The first module of Part 1 (21) integrates SP (Super P-Li, conductive agent) unpacking and feeding and SP metering tanks, CMC (carboxymethyl cellulose, dispersant) feeding and CMC metering tanks, and main powder unpacking and feeding and main powder metering tanks. The total number of integrated first modules is 24, with 6 modules fixedly installed together, thus it can be counted as 4. The first module of Part 2 (22) integrates a transition chamber (sending chamber) after mixing the main powder and auxiliary powder, with 12 units. The first module of Part 3 (23) integrates a main powder unpacking and feeding and main powder metering tank, with 6 units, and these 6 integrated first modules are fixedly connected, thus it can be counted as 1.

[0043] See Figure 3The second module of Part 1 (31) integrates a mixer, a slurry (semi-finished product) circulation tank, and a finished slurry buffer tank, resulting in a total of three second modules. The second module of Part 2 (32) integrates a binder 1 (solvent) feeding and metering tank, a binder 2 (solvent) feeding and metering tank, and a DIW (deionized) water feeding and metering tank, resulting in a total of three second modules. The second module of Part 3 (33) integrates a transition chamber (sending chamber) after mixing the main powder and auxiliary powder, resulting in a total of three second modules. The second module of Part 4 (34) integrates a mixer and a slurry (semi-finished product) circulation tank, resulting in a total of three second modules.

[0044] In the first embodiment, the equipment is mounted on a first mounting frame and a second mounting frame (e.g., a steel frame) to integrate them into a first module and a second module. The equipment in the first module and the second module can be exposed in a first area M and a second area O, respectively. Alternatively, the first mounting frame can be encapsulated using a common encapsulation plate to seal each first module and isolate it from the external environment. Furthermore, after the first and second mounting frames are encapsulated with the encapsulation plate, they also form a container for transportation, facilitating equipment transport. The number and types of equipment in the module can be designed according to the dimensions of the container.

[0045] Table 1 shows Figure 1 The original scheme and Figure 2 , Figure 3 The comparison of the area of ​​the first region M, the height of the factory building, the volume of the factory building, and the equipment debugging cycle after transportation in the first embodiment of the new solution of this application shows that, compared with the original solution, the embodiment of this application reduces the area of ​​the first region M (i.e., the environmental parameter requirements are relatively high), the height of the factory building, the volume of the factory building, and the equipment debugging cycle.

[0079] Table 7 shows Figure 13 The original scheme and Figure 14 The comparison of the number of devices / modules in the battery production line 140 of the fifth embodiment of the new solution of this application shows that the new solution of this application integrates the equipment into 6 modules, that is, the number of modules that need to be spliced ​​and assembled after transportation is 6, which is 12 fewer than the original solution.

[0080]

[0081] Table 7

[0082] In other embodiments, the battery production line 140 may be partially modularized, and some large or heavy single-unit equipment (such as the two roller presses in the main clean module 143) may not be modularized. During equipment installation, such single-unit equipment is arranged separately and installed on-site with adjacent modular equipment.

[0083] This application provides a prefabricated battery production line module. By modularly integrating equipment used in the lithium battery processing process and controlling the microenvironment of each module, the module can be quickly assembled and connected during subsequent production line installation. This eliminates the need to start with the installation of disassembled equipment, significantly reducing the production line lead time. This is particularly beneficial when equipment is manufactured domestically but installed overseas; modular integration in China followed by shipping reduces transportation costs and shortens the lead time. Furthermore, the modular integration and enclosed control of the microenvironment within the production line reduce the need for strict control of the overall workshop environment. The modularly integrated equipment can be debugged immediately after integration, without waiting for the entire production line to be installed, further shortening the production line lead time.

[0084] In the battery production line of this application, a plurality of production devices in a first region (e.g., M) have the same environmental parameter requirements. At least some of these devices are mounted on a first mounting frame to be integrated into a plurality of first modules, achieving modular integration of the equipment. This facilitates equipment transportation and reduces the number of modules that need to be installed after transportation. By integrating equipment with different environmental parameter requirements in different regions, the area of ​​the first region (with the highest environmental parameter requirements) is reduced, thereby lowering costs. Furthermore, the mounting frame is encapsulated using a packaging plate to achieve module sealing and facilitate transportation. The types and quantities of equipment in the modules are designed according to the dimensions of the container, making efficient use of container space.

[0085] The embodiments of this application use steel structures such as a first mounting frame and a second mounting frame as a skeleton. When the equipment is modularly integrated, it is installed and fixed on the skeleton. For the steel frame connection of components that will generate vibration (such as mixing tanks) and precision components, shock-absorbing pads are added at the connection points to buffer the vibration generated during the operation of the production equipment and to prevent the skeleton from transmitting vibration to the precision components. Particularly precision components (such as metering tanks) can also be isolated from the steel frame after transportation and placed directly on the ground. During modular integration, the water inlet and outlet pipes, power lines, clean air supply pipes, fire protection pipes, etc. required by the relevant equipment are integrated and installed in the modules. Adjacent modules are quickly installed and fixedly connected through connectors. Each microenvironment of the production line (e.g., the first area M, the second area O, and the third area N) is controlled separately, and adjacent modules are fixed and sealed. The specific fixing and sealing methods are not limited, and can be achieved through conventional flanges, sealing rings, gaskets, etc. Auxiliary piping is integrated into the modules. When assembling different modules, connections between modules can be achieved simply by quick plugging at the connection points, reducing the time spent on connection and debugging of wiring and equipment during installation after transportation. Modularization reduces the number of devices required because some functions can be shared, and some components do not need to be duplicated.

[0086] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
