The quality and efficiency of battery cell processing are improved by the single-piece flow symmetry method of the component segment. The side seam battery processing segment is set after the component segment process. The side seam welding segment receives the first battery module and the second functional component processed by the component segment, and combines them with several loading and transporting mechanisms 121 and several side seam welding fixtures 122 to form a second battery module. The several loading and transporting mechanisms 121 and several side seam welding fixtures 122 are arranged in pairs, such as 1 to 2, 2 to 4, or 1 to 1. To improve production efficiency, it is important to understand that the plurality of material handling mechanisms 121 and the plurality of side seam welding fixtures 122 are configured in conjunction with the component segment and can be configured according to the number of channels in the component segment that form the first battery module. Since this embodiment adopts a dual-channel synthesis system for processing the battery cells, and two battery cell stacking devices 114-1 to form a four-channel first combination system for producing the first battery module, preferably four material handling robots 121 and four side seam welding fixtures 122 are used in conjunction with the first combination system to form a four-channel second combination system for producing the second battery module; thus improving production efficiency.

[0181] In this embodiment, the processing of the battery cell includes one or more of the following steps: bottom cleaning, barcode scanning, surface cleaning, gluing, adhesive application, end plate installation, insulating cover installation, and unloading. The processing of the functional components includes one or more of the following steps: loading, conveying, cleaning, gluing, barcode scanning, and unloading. Since the functional components include a first functional component and a second functional component, the automated production of the first battery module is achieved by processing and combining the battery cell and the first functional component through the component segment 110. Because the processing of the second functional component is completed simultaneously with the formation of the first battery module, it should be understood that this simultaneous completion includes... The number of second functional components installed on the first battery module, or the number of second functional components required to form the second battery module, can be adjusted by changing the processing and conveying speed of the second functional components or by increasing the processing station of the second functional components. This allows for synchronous completion with the first battery module, so that the side seam welding section 120 can simultaneously pick up the first battery module and the matching second functional components, thereby quickly and efficiently forming the second battery module. By sequentially setting up the component section 110 and the side seam welding section 120, the integrated production of the first and second battery modules is achieved, reducing labor costs and improving production efficiency.

[0182] In one embodiment, the component segment 110 includes:

[0183] The synthesis front section 116 is used for transporting and initial processing of the battery cells;

[0184] The middle section 117 is used for step-by-step delivery and secondary processing of the battery cells;

[0185] The post-assembly section 118 is used to combine the battery cell and the first functional component, and to transport them.

[0186] The front assembly section 114 is used to stack the assembled battery cells and the first functional components to form a first battery module; and

[0188] The synthesis front section 116, synthesis middle section 117, synthesis rear section 118, and combination front section 114 are arranged sequentially along the processing steps.

[0189] And / or, the synthesis front section 116, synthesis middle section 117, synthesis back section 118 and combination front section 114 are symmetrically arranged in twos, thereby forming a dual-channel synthesis system;

[0190] The middle section 115 of the assembly is disposed on one side of the front section 114 of the assembly.

[0191] In this embodiment, by sequentially arranging the synthesis front section 116, synthesis middle section 117, synthesis back section 118, and combination front section 114, the entire cell production line is made up, automated, and integrated, standardizing the cell production process and improving production efficiency. Since there are two of each of the synthesis front section 116, synthesis middle section 117, synthesis back section 118, and combination front section 114, a dual-channel synthesis system is formed. The symmetry line is set on the same straight line. The dual-channel synthesis system enables the simultaneous processing of two cells, improving production efficiency and output. Furthermore, the dual-channel synthesis system allows for alternating use. When a device or process in one channel fails, the other channel can continue processing, ensuring production stability.

[0192] As needed, the middle section 115 is set on one side of the front section 114 to ensure that the first battery module and the second functional component can be output synchronously. This facilitates the side seam welding section 120 in acquiring the first battery module and the second functional component, optimizes the spatial layout, and improves the efficiency of automated and integrated production. It should be noted that the middle section 115 may also include a second functional component unloading and placement section for placing the processed second functional component, so as to ensure that the side seam welding section 120 can acquire a sufficient number of second functional components in a timely manner, and avoid the side seam welding section 120 failing to acquire the number of second functional components forming the second battery module and the number of first battery modules in a timely manner.

The second conveying mechanism 112 is located in the working area of ​​the second feeding unit and is used to perform step-by-step conveying on the battery cells so that the second feeding unit performs secondary processing on the battery cells in sequence.

[0199] And / or, the post-composition section 118 includes a third feeding unit and a third conveying mechanism 113. The third feeding unit is used to feed the first functional component and combine it with the battery cell. The third conveying mechanism 113 is arranged in the working area of ​​the third feeding unit and is used to convey the first functional component and the battery cell so that the third feeding unit combines the battery cell and the first functional component in sequence.

The first feeding unit, the second feeding unit, and the third feeding unit of the module segment 110 respectively process the battery cells conveyed by the first conveying mechanism 111, the second conveying mechanism 112, and the third conveying mechanism 113. This achieves automated, standardized, integrated, and continuous automatic conveying and processing of battery cells, forming battery modules through integrated production. This reduces labor costs, improves production efficiency, optimizes the design layout, standardizes the overall workshop layout, and efficiently utilizes space resources.

[0203] In operation, the battery cells are first conveyed by the first conveying mechanism 111, the second conveying mechanism 112, and the third conveying mechanism 113 respectively. Then, the first feeding unit, the second feeding unit, and the third feeding unit of the component section 110 process the conveyed battery cells in sequence. The battery cells and end plates are then stacked by the front assembly section 114 to form the first battery module. At the same time, the side plates are conveyed and processed by the middle assembly section 115, which greatly optimizes the production process. The processing of the end plates or side plates includes at least one or more of cleaning (plasma cleaning or other forms of surface cleaning), photographing (for detection and positioning), and applying adhesive or gluing, which improves production quality and efficiency and facilitates the subsequent side seam welding section 120 to pick up and process the battery module and side plates for welding, ensuring the production cycle.

On the other side of the arc-shaped heating storage unit 214-1, each heating and handling robot 214-2 is responsible for four heating storage units. When the second battery module is delivered to the position by the sixth conveying mechanism, the two heating and handling robots 214-2 respectively grab the second battery module and transport it to the arc-shaped heating storage unit 214-1 for heating. An empty pallet (this empty pallet is a pallet used in conjunction with the side seam welding conveying section, which can limit and fix one or more second battery modules as needed) is transported forward or transported and collected by the heating and handling robots 214-2, waiting to place the heated second battery module. After the second battery module is heated, the heating and handling robots 214-2 grab the second battery module and place it on the delivered empty pallet for the next process.

[0308] As needed, the end of the sixth conveying mechanism passes through the arc-shaped heating chamber 214-1. The sixth conveying mechanism is a dual-channel conveying mechanism to improve production efficiency and speed up the production cycle. On the other side of the arc-shaped heating chamber 214-1, corresponding to the position of the sixth conveying mechanism, an eighth conveying mechanism is also set up. The heated battery modules are conveyed to the stationary unit 215 for stationary treatment through the eighth conveying mechanism. During operation, the second battery module is conveyed to the second heating unit 214 through the upper layer of the side seam welding mechanism. The heating and handling robot 214-2 accurately positions and grasps the delivered second battery module and moves it to the arc-shaped heating chamber 214-1 for heating treatment.

Two of these robots are used to transport the second battery module after static storage units 215-1 for static processing, and the third robot is located after static storage units 215-1 to rewind the second battery module after static processing. The four static storage units 215-1 and the two rewinding robots 215-2 are symmetrically arranged on both sides of one end of the sixth or eighth conveying mechanism. During operation, after the second battery module is heated and transported to its position by the sixth or eighth conveying mechanism, the rewinding robot 215-2 picks up and transports the second battery module to the static storage units 215-1 for static processing. After static processing is completed, the module is then transported to the static storage units 215-1 for static processing.

[0384] One embodiment of the present invention also provides a manufacturing process, specifically a manufacturing process using the battery production line 300 as described above, comprising the following steps:

[0385] A. The battery cell and the first functional component are processed in a single-piece flow-symmetric manner through the component segment 110 and stacked to form the first battery module, while the second functional component is processed at the same time.

[0386] B. Obtain the first battery module and the second functional component through the side seam welding section 120, and assemble the first battery module and the second functional component to form the second battery module.

[0388] D. Receive the third battery module through the bus welding front section 220, and perform photo addressing and bus welding on the third battery module;

[0389] F. The third battery module, processed by the busbar welding front section 220, is received through the busbar welding rear section 230, and the third battery module is top-encapsulated and visually inspected to form the fourth battery module.

[0390] E. The fourth battery module formed after the busbar welding section 230 is processed is transported to the packaging section 310, and the packaging section 310 automatically packages the fourth battery module and unloads the packaged fourth battery module, thereby completing the production of the overall battery module.

[0391] The production of the overall battery module includes the sequential formation of a first battery module, a second battery module, a third battery module, and a fourth battery module.

[0392] In this embodiment, the integrated production of the entire battery module is achieved by sequentially setting up the component section 110, the side seam welding section 120, the heating and settling section 210, the busbar welding pre-section 220, the busbar welding post-section 230, and the packaging and unloading section 310. Through the automation, integration, standardization, and orderly production of the battery production line 300, each process of the battery production line 300 is clearly defined and orderly. The cells, functional components, the first battery module, the second battery module, the third battery module, and the fourth battery module are sequentially transported by various conveying mechanisms, efficiently completing the production of the entire battery module. The trays are returned and recycled through the lower layers of each conveying mechanism, reducing resource waste. NG carts 127-2 and / or NG unloading stations set up at each inspection station promptly address any defects. The first, second, third, and fourth battery modules, functional components, and battery cells are discharged and processed to prevent them from flowing into the next process for further processing, thus avoiding resource waste and preventing multiple problems from occurring simultaneously, which could lead to the battery module being unrecyclable. At the same time, the quality of the battery cells, first, second, third, and fourth battery modules, and functional components after each process is strictly guaranteed. Through the layout and design of each processing section, the high efficiency of the production cycle is ensured, with the entire production line's cycle time controlled within seconds, greatly improving overall production efficiency. The advantages, beneficial effects, and implementation methods of the battery production line 300 have been described above. Since this production process uses the battery production line 300 described above, it also possesses the corresponding advantages, beneficial effects, and implementation methods, which will not be repeated here.

[0393] The aforementioned battery production line 300 and its production process can process any specification or type of battery cell, first battery module, second battery module, third battery module, fourth battery module, and functional components. Each process of the battery production line 300 is equipped with a rapid adjustment mechanism and / or a rapid changeover mechanism. The rapid adjustment mechanism (and / or rapid changeover mechanism) is used to quickly adjust (and / or change) the corresponding processing mechanisms for battery cells, first battery modules, second battery modules, third battery modules, fourth battery modules, and functional components of different specifications and / or different types, thereby enabling the processing of battery cells, first battery modules, second battery modules, third battery modules, fourth battery modules, and functional components of different specifications and / or different types.

[0394] The robot described above is a multi-axis rotary robot that can perform arbitrary rotational movements in the X, Y, and Z planes, thereby achieving flexible grasping actions. In addition, the robot is equipped with a camera module, which facilitates precise positioning and grasping actions, enabling efficient and error-free execution of work and avoiding damage to the workpiece due to improper grasping.

[0395] The aforementioned conveying mechanisms (including the first to twelfth conveying mechanisms) are all equipped with upper-level processing conveying and lower-level return conveying (except for the eleventh conveying mechanism A, which is used to convey the third battery module to the first process). They are equipped with corresponding trays, thus enabling the sequential conveying of the first, second, third, and fourth battery modules or functional components along the processing direction via the upper-level processing conveying, achieving production automation and integration. The lower-level return conveying recycles empty trays used for processing the first, second, third, and fourth battery modules or functional components, reducing production costs and avoiding resource waste. Furthermore, the coordinated or combined use of multiple conveying mechanisms further enhances production automation, ensuring the overall automation and integrated production of the battery production line 300, reducing labor costs. Only a small number of personnel are needed to meet the production line's operational needs, significantly reducing production costs and improving production efficiency. The aforementioned battery production line 300 is equipped with a recycling unit, NG discharge station, or NG trolley 127-2 after each inspection process or after each process. This is used to promptly recycle and process unqualified battery cells, first battery modules, second battery modules, third battery modules, fourth battery modules, or functional components. The unqualified products are sorted and processed centrally to prevent them from flowing into the next process, which would be inconvenient for workers to recycle. This also avoids resource waste, strictly ensures product quality, and greatly improves production quality.

[0396] The battery production line 300 is also equipped with corresponding supply equipment and / or control equipment to ensure the normal operation of the production line and to control the working equipment of the production line, thereby realizing the production of various types of cells or complete battery modules on the entire line.

[0397] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
