Description

Technical Field

[0001] This utility model belongs to the technical field of battery production equipment, specifically, it relates to a two-sealing machine. Background Technology

[0002] Lithium-ion batteries are characterized by high energy density, high power, and long lifespan, and are widely used in energy storage, 3C, automotive, and even military fields; lithium battery production equipment is also constantly being updated and iterated with the development of lithium battery technology.

[0003] Currently, most manual loading and unloading secondary sealing machines used in battery cell production have a linear layout, with a large distance between the loading and unloading stations. This often requires at least two people to operate simultaneously, one loading at the front and the other unloading at the back, resulting in high labor costs. Furthermore, communication between two people operating a single secondary sealing machine is often unreliable, and operator inadequate preparation may lead to injuries when starting the machine after maintenance or testing. In addition, linear secondary sealing machines, especially those with sequential sealing on both sides, have very low space utilization and are quite long, making it difficult for operators to fully monitor the secondary sealing process. This results in a significant delay in problem detection compared to when the problem occurs, which is detrimental to practical application and cost control for manufacturing companies.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0005] To address one of the problems in the prior art, this invention provides a double-sealing machine. By improving the arrangement of the various stations of the double-sealing machine, the interval between the loading and unloading stations is shortened, significantly reducing the manpower required to operate the double-sealing machine and the operator's travel distance. Only one person can complete the loading and unloading without stopping the machine, greatly reducing labor costs and workload.

[0006] To solve the above-mentioned technical problems, this utility model provides a two-stage sealing machine, including a first working area and a second working area arranged parallel to a first direction and spaced apart, and a third working area connecting the first working area and the second working area.

The discharging section is located downstream of the first working area along the first direction. The material preparation section is located between the feeding section and the discharging section. The feeding section and the discharging section respectively form a feeding station and a discharging station on the side of the first working area away from the second working area. The discharge station of the material preparation section is connected to the feeding station of the sealing section located in the second working area through the third working area. The material from the feeding section is transferred to the feeding station of the material preparation section, processed by the material preparation section, and then enters the sealing section for sealing. Finally, the material from the discharge station of the sealing section is transported to the discharging station through the third working area.

[0007] Furthermore, the feeding station and discharging station of the packaging section are located downstream of the second working area along the first direction, and the third working area is located along the second direction perpendicular to the first direction, and is connected to the downstream side of the first working area and the second working area along the first direction, respectively.

[0008] Furthermore, the material preparation section's discharge station is located along the first direction on the side of the material preparation section close to the unloading section. The third work area includes a first conveying component located along the second direction, with the two ends of the first conveying component corresponding to the material preparation section's discharge station and the packaging section's infeed station, respectively.

[0009] Furthermore, the third work area also includes a second conveying component arranged along the second direction, which is used to transport materials from the unloading station of the packaging section to the unloading section.

[0010] Furthermore, the secondary sealing machine also includes a post-processing section located in the third work area. The post-processing section is located on the conveying path of the second conveying component and is used to test and screen the packaged cells.

[0011] Furthermore, the material preparation section includes a piercing station, a cutting station, a fine sealing station, and a corner sealing station arranged sequentially along the first direction. The piercing station and the corner sealing station are the feeding station and the discharging station of the material preparation section, respectively.

[0012] Furthermore, the material preparation section also includes a shape adjustment station located between the piercing station and the cutting station, used to adjust the battery cells from the piercing station to a suitable shape for cutting; the shape adjustment station includes a third conveying component arranged along the second direction, the shape adjustment station is located at one end of the third conveying component, and the other end of the third conveying component forms an inspection station on the side of the first work area away from the second work area, the inspection station is located between the loading station and the unloading station.

[0013] Furthermore, the encapsulation section includes a first encapsulation line and a second encapsulation line arranged parallel to each other along a first direction, the first encapsulation line and the second encapsulation line being used to encapsulate both sides of the battery cell, respectively.

[0014] The first packaging line is arranged in the opposite direction to the first direction, and the feeding station of the packaging section is the feeding station of the first packaging line; the second packaging line is arranged in the first direction, and the discharging station of the packaging section is the discharging station of the second packaging line; the discharging station of the first packaging line is connected to the feeding station of the second packaging line.

[0015] Furthermore, the first packaging line and the second packaging line include a positioning station, an edge cutting station, a first folding station, a first heat pressing station, a second folding station, a second heat pressing station, an adhesive application station, and a shaping station arranged in sequence; the positioning station and the shaping station are the feeding station and the unloading station of the first packaging line and the second packaging line, respectively.

[0016] Preferably, the second packaging line further includes a transfer station located downstream of the shaping station, the transfer station being the unloading station of the second packaging line.

[0017] Furthermore, the discharge station of the first packaging line and the feed station of the second packaging line are aligned, the transfer station of the second packaging line is aligned with the second conveying component along the second direction, the ends of the first packaging line and the second packaging line away from the third work area are connected by a fourth conveying component arranged along the second direction, and the end of the second packaging line near the third work area has a fifth conveying component arranged along the second direction. The battery cell located at the transfer station is conveyed to the second conveying component via the fifth conveying component.

[0018] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0019] 1. By improving the layout of each station of the secondary sealing machine, the interval between the loading and unloading stations has been shortened, which greatly reduces the manpower required to operate the secondary sealing machine and the operator's operating stroke, enabling one person to complete the loading and unloading operations of the secondary sealing machine without stopping the machine.

[0020] 2. The dust cover of the secondary sealing machine is equipped with a large number of inspection windows and doors, but they are closed by default and are equipped with an opening detection device. That is, the equipment will automatically stop and manual start is prohibited when the inspection windows and doors are open. In normal state, the secondary sealing machine only has three operating stations connected to the inside of the secondary sealing machine: the loading station, the inspection station, and the unloading station. This utility model sets the above three stations on the same side of the secondary sealing machine. After the equipment is inspected and maintained, the operator can directly observe whether there are any operators operating at the above three stations, and then start the secondary sealing machine in a safe state, avoiding personal injury caused by untimely communication between personnel.

[0021] 3. The first and second work areas are set up in parallel with each other, and the third work area connects the first and second work areas from the downstream side of the first work area along the first direction. This arrangement shortens the overall length of the second sealing machine, which helps to save the layout space of the second sealing machine; and the gap formed between the first and second work areas can serve as a corridor for manual maintenance, improving the convenience of maintenance.

[0022] 4. The encapsulation section includes a first encapsulation line and a second encapsulation line arranged in parallel. The two are used to encapsulate different sides of the battery cell respectively. Compared with equipment that encapsulates both sides at the same time, the adjustment and maintenance are simpler and more convenient.

[0023] 5. An inspection station is established between the loading and unloading stations. After observing the cell status at the inspection station, operators can move to the loading or unloading station with a shorter distance, shortening their travel time. By observing the cells during material preparation at the inspection station, cell defects can be detected in time before the cells are packaged, allowing for quick identification of the cause of the defects and timely adjustment of the secondary sealing machine. This avoids material waste due to delayed defect observation, improves the efficiency of the secondary sealing machine, and helps reduce production costs. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] This utility model provides a two-sealing machine, such as Figures 1 to 7 As shown, the overall layout of the secondary sealing machine is divided into three areas. The first and second areas are arranged parallel to and spaced apart along the first direction. The third area C is set at an angle to the first direction, connecting the first area A and the second area B. The first area A includes a loading section 1, a material preparation section 2, and a unloading section arranged along the first direction. The unloading section is located downstream of the first area A along the first direction. The material preparation section 2 is located between the loading section 1 and the unloading section. The loading section 1 and the unloading section form a loading station 11 and an unloading station 5 on the side of the first area A away from the second area B. The secondary sealing machine has a sealing section 3 for sealing the battery cells. The sealing section 3 is equipped with... In the second work area B, after the battery cells are loaded at the loading station 11 in the first work area A, they are transported to the packaging section 3 in the second work area B via the third work area C for packaging. Then, they are transported to the unloading station 5 via the third work area C to complete the second sealing process. Through the above-mentioned improvement of the arrangement of the manual loading and unloading of the second sealing machine, the distance between the loading station 11 and the unloading station 5 is greatly shortened, and the travel distance of the operators is shortened. The second sealing machine, which originally required two people to be responsible for loading and unloading, can now be operated by only one person without stopping the machine or running it idle, thus reducing the manual operation cost of the second sealing machine.

[0037] Specifically, when using a two-sealing machine to encapsulate battery cells, the operator first places the battery cell at the loading station 11 of the loading section 1. After passing through the loading section 1, the battery cell is moved to the feeding station of the material preparation section 2. After being processed in the material preparation section 2, the battery cell is moved to the discharge station of the material preparation section 2. It is then transferred by the conveying component set in the third work area C to the feeding station of the encapsulation section 3 in the second work area B. After encapsulation is completed, the battery cell is transferred to the discharge station of the encapsulation section 3. It is then transferred by the conveying component set in the third work area C to the unloading section. Finally, the operator takes out and collects the encapsulated battery cell that has arrived at the unloading station 5, completing the entire two-sealing process.

[0038] In the above scheme, the loading station 11 is one of the stations included in the loading section 1. It may also include other functional stations, such as: barcode scanning and identification station 13, inspection station, defective product collection station (i.e., NG collection station 14 before packaging), etc. When multiple cells enter the loading station 11 at one time, the loading section 1 also includes a sorting station 12.

[0039] It should also be noted that the conveying component used to transfer the battery cell from the discharge station of the material preparation section 2 to the feeding station of the packaging section 3 can be the same as the conveying component used to transfer the battery cell from the discharge station of the packaging section 3 to the unloading section, or different conveying components can be used. When different conveying components are used, the two conveying components can be set side by side in the same horizontal plane, or they can be set in different horizontal planes, such as staggered at different heights, or stacked on top of each other.

[0040] Furthermore, the conveying components mentioned in the embodiments of this utility model can be configured as transfer clamps, transfer robots, transfer conveyor belts, or other common material transfer devices according to actual usage requirements. The conveying components mentioned in the embodiments of this utility model can be integrated or segmented. Integrated means that the battery cells are transported from one end of the conveying component to the other end through a continuous conveying device, while segmented means that the battery cells are transported from one end of the conveying component to the other end through two or more segments of conveying devices. In the segmented conveying component, the types of each segment of the conveying device can be selected according to actual production requirements, and can be set to be the same or different.

[0041] Cleaning devices, such as vacuum dust removal devices, dust removal brushes / rollers, and demagnetizing devices, can be installed on the conveying components as needed. The cleaning devices can be set according to actual requirements, and since they are common devices in this field, they will not be described in detail here.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0043] As an embodiment of the present invention, this embodiment provides a two-sealing machine, wherein the feeding section 1, the material preparation section 2 and the unloading section of the first working area A are arranged sequentially along the first direction, and the feeding station and the unloading station of the material preparation section 2 are located on both sides of the material preparation section 2 along the first direction.

[0044] Specifically, such as Figure 1 As shown, the feeding station of material preparation section 2 is located on the side of material preparation section 2 facing the loading section 1, and the discharging station of material preparation section 2 is located on the side of material preparation section 2 facing the unloading section. The battery cells from loading section 1 can be transported to the feeding station of material preparation section 2 with a shorter conveying distance, shortening the conveying time and improving the operating efficiency of the secondary sealing machine. The discharging station of material preparation section 2 is set close to the unloading section, and the third working area C is also connected from the first working area A and the second working area B along the downstream side of the first direction, so that the secondary sealing machine is in a horizontal "U" shape. At this time, the gap between the first working area A and the second working area B can serve as a manual passage for the inspection and maintenance of the secondary sealing machine, improving the convenience of maintenance of the secondary sealing machine. In other embodiments, the overall setting direction of the second working area B can also be adjusted according to the actual production layout.

[0045] In this embodiment, the material preparation section 2's discharge station and the packaging section 3's infeed station, as well as the packaging section 3's discharge station and the unloading section, can be connected using the same conveying component or different conveying components. When using the same conveying component, robotic arms for transferring battery cells are provided between the conveying component and the material preparation section 2, the packaging section 3, and the unloading section 5. The material preparation section 2 includes a piercing station 21, a cutting station 23, and a precision sealing station 24 arranged sequentially along the first direction. The corner sealing station 25 includes a piercing station 21, which is the feeding station of the material preparation section 2, and a corner sealing station 25, which is the discharging station of the material preparation section 2. The packaging section 3 includes a positioning station 31, an edge cutting station 32, a first folding station 33, a first heating station 34, a second folding station 35, a second heating station 36, an adhesive application station 37, and a shaping station 38, which are arranged sequentially along the cell conveying path. The positioning station 31 is the feeding station of the packaging section 3, and the shaping station 38 is the discharging station of the packaging section 3. The overall operation process of the two-sealing machine is as follows.

[0046] After the battery cell enters the loading section 1 from the loading station 11, it is first received at the puncture station 21. After being punctured, it is transferred to the cutting station 23 to remove the air bag, and then to the precision sealing station 24 to seal the cut opening. After that, it is transferred to the corner sealing station 25 for corner sealing. After the corner sealing is completed, the material preparation is completed. It is then transferred by a robot to the conveying component of the third work area C, and then transported to the second work area B. After that, it is transferred by a robot to the positioning station 31. After receiving the battery cell, the positioning station 31 first positions the battery cell so that it can be successfully packaged. Then, it goes through one fold, one heat setting, two folds, two heat setting and adhesive application in sequence, and then is transferred to the shaping station 38 for shaping. The packaged battery cell is then transferred by a robot to the conveying component, and then transported by the conveying component to the first work area A. After that, it is transferred by a robot to the unloading section. The operator takes out the battery cell from the unloading station 5, completing the entire two-sealing process.

[0047] As can be seen from the above operation process, the conveying component needs to transport the battery cells back and forth between the first work area A and the second work area B. Therefore, before the battery cells are transported from the material preparation section 2 to the packaging section 3, the battery cells packaged in the packaging section 3 should first be transported to the unloading section 5 to ensure that there is only one battery cell on the conveying component during the reciprocating transport process. In order to improve efficiency, the battery cells waiting to be transported can be gripped by the robot first. That is, the robot can act as a transfer device in the battery cell transport process. The battery cells waiting to be transferred in the material preparation section 2 and the packaging section 3 will not occupy the work position and cause the material preparation section 2 and the packaging section 3 to be unable to operate continuously.

[0048] In this embodiment, the positioning station 31, the edge cutting station 32, the first folding station 33, the first ironing station 34, the second folding station 35, the second ironing station 36, the adhesive application station 37, and the shaping station 38 are all configured to simultaneously encapsulate both sides of the battery cell, which shortens the battery cell encapsulation steps and improves the production efficiency of the second sealing machine. Example

[0049] As another embodiment of the present invention, this embodiment makes the following improvements based on embodiment one.

[0050] In this embodiment, as Figure 2 As shown, the third work area C includes a first conveying component 6 and a second conveying component 7 arranged side by side. The first conveying component 6 connects the material preparation section 2's discharge station with the packaging section 3's infeed station, and the second conveying component 7 connects the packaging section 3's discharge station with the unloading section. By independently conveying the battery cells through the two conveying components, the defect that a set of conveying components can only achieve unidirectional conveying at the same time is overcome, which can significantly improve the second sealing efficiency of the second sealing machine.

[0051] Furthermore, such as Figure 3As shown, the third work area C also includes a post-processing section 4, which is located on the conveying path of the second conveying component 7. After the battery cells are packaged by the packaging section 3, they undergo post-processing during the process of being conveyed to the discharge section by the second conveying component 7. This further enhances the functional integration of the secondary sealing machine and improves its space utilization. In this embodiment, the post-processing section 4 includes a side voltage & resistance testing station 41, a weighing and scanning station 42, and a post-packaging NG collection station 43, arranged sequentially along the conveying path of the second conveying component 7. Depending on actual needs, in other embodiments, the length of the third work area C in the second direction can be extended to increase the number of stations on the conveying path of the second conveying component 7, further improving the functional integration of the secondary sealing machine.

[0052] Considering that when the various work areas of the packaging section 3 are arranged in a "I" shape, it is necessary to return the battery cells at the shaping station 38 to the third work area C over a long distance. In order to improve space utilization, such as Figure 4 As shown, the above-mentioned workstation can also be bent in the opposite direction between the first ironing workstation 34 and the second folding workstation 35, so that the shaping workstation 38 is set close to the third work area C, which is conducive to improving space utilization. Example

[0053] As another embodiment of the present invention, this embodiment is further improved on the basis of embodiment two as follows.

[0054] In this embodiment, as Figure 5 and Figure 6 As shown, the encapsulation section 3 located in the second work area B includes a first encapsulation line 3a and a second encapsulation line 3b that are parallel to each other along a first direction. The first encapsulation line 3a and the second encapsulation line 3b are used to encapsulate the opposite sides of the battery cell, respectively. That is, after the battery cell completes the encapsulation on one side of the first encapsulation line 3a, it is transported to the second encapsulation line 3b to continue to complete the encapsulation on the opposite side. Although this setting method prolongs the encapsulation time, compared with encapsulation on both sides at the same time, the maintenance and adjustment of the equipment is easier, which greatly reduces the maintenance difficulty and maintenance time.

[0055] In this embodiment, the first packaging line 3a and the second packaging line 3b have completely opposite transport paths. That is, the first packaging line 3a is set in the opposite direction along the first direction, and the second packaging line 3b is set along the first direction. The starting side of the first packaging line 3a and the ending side of the second packaging line 3b are located downstream of the second work area B along the first direction. This arrangement is more compatible with the position of the third work area C, shortening the distance of the battery cell transported between different work areas. At this time, the feeding station of the first packaging line 3a is also the feeding station of the packaging section 3, and the discharging station of the second packaging line 3b is also the discharging station of the packaging section 3.

[0056] Specifically, the first packaging line 3a includes a positioning station 31, a trimming station 32, a first folding station 33, a first heat pressing station 34, a second folding station 35, a second heat pressing station 36, an adhesive application station 37, and a shaping station 38 arranged sequentially along the cell conveying path. The positioning station 31 in the first packaging line 3a also serves as the feeding station for the first packaging line 3a, and the shaping station 38 in the first packaging line 3a serves as the unloading station for the first packaging line 3a. The second packaging line 3b includes a positioning station 31, a trimming station 32, a first folding station 33, a first heat pressing station 34, a second folding station 35, a second heat pressing station 36, an adhesive application station 37, a shaping station 38, and a transfer station arranged sequentially. Position 39, wherein the positioning station 31 of the second packaging line 3b also serves as the feeding station of the second packaging line 3b, and the transfer station 39 of the second packaging line 3b serves as the unloading station of the second packaging line 3b. The forming station 38 of the first packaging line 3a and the positioning station 31 of the second packaging line 3b form a cell transport path, so that the cell can be packaged by the first packaging line 3a and the second packaging line 3b in sequence. This arrangement allows the two sides of the battery to be packaged in the two packaging lines in sequence. Although it increases the number of stations the cell passes through in the packaging process, the equipment layout of the two packaging lines does not interfere with each other, which greatly reduces the difficulty of equipment adjustment and maintenance. Example

[0057] As another embodiment of the present invention, this embodiment is further improved on the basis of embodiment three as follows.

[0058] In this embodiment, as Figure 7 As shown, the second packaging line 3b also includes a transfer station 39 located downstream of the shaping station 38. After the battery cells are shaped at the shaping station 38 of the second packaging line 3b, they are transported to the transfer station 39 and then from the transfer station 39 to the second conveying assembly 7.

[0059] Specifically, in this embodiment, the first packaging line 3a and the second packaging line 3b are arranged side by side. The discharge station of the first packaging line 3a and the feed station of the second packaging line 3b are aligned along the second direction, and the feed station of the first packaging line 3a and the discharge station of the second packaging line 3b are aligned. At this time, the transfer station 39 located at the end of the second packaging line 3b protrudes from the first conveying section along the first direction and is aligned with the second conveying component 7 along the second direction. In this scheme, by setting the transfer station 39, the clearance between devices is achieved.

[0060] Furthermore, a fourth conveying assembly 9 is provided at the end of the first packaging section 3 and the second packaging section 3 furthest from the third work area C. The fourth conveying assembly 9 is a conveyor belt perpendicular to the first packaging line 3a and the second packaging line 3b, located upstream of the discharge station of the first packaging line 3a and the discharge station of the second packaging line 3b along a first direction. The battery cells that have been shaped at the shaping station 38 of the first packaging line 3a are conveyed to the end of the fourth conveying assembly 9 near the first packaging line 3a. After the battery cells are transferred to the end near the second packaging line 3b by the fourth conveying assembly 9, they are then conveyed to the end of the second packaging line 3b. The positioning station 31 of the second packaging line 3b continues the packaging on the other side; similarly, a fifth conveying component 10 is also provided at one end of the second packaging line 3b near the third work area C. The fifth conveying component 10 is arranged along the second direction and is located downstream of the transfer station 39 along the first direction. The battery cells located at the transfer station 39 are transported to the second conveying component 7 via the fifth conveying component 10. The above arrangement effectively avoids interference between the conveying components and adjacent stations when they are working by adding the transfer station 39 as a clearance position, thereby improving the working stability of the second packaging machine.

[0061] Furthermore, in this embodiment, the end of the second conveying component 7 near the second work area B is located between the feeding station of the first packaging line 3a and the fifth conveying component 10, forming a receiving station between the feeding station of the first packaging line 3a and the fifth conveying component 10. The receiving station is located downstream of the feeding station of the first packaging line 3a along the first direction. Including the fourth conveying component 9 and the fifth conveying component 10, the spacing between any two adjacent stations along the first direction in the second work area B is the same, that is, the distance moved by the battery cell is the same whether it is transferred between two adjacent stations or between a station and a conveying component. This arrangement further improves the compactness of the arrangement of each station in the second work area B. Whether the movement of the battery cell is achieved by a conveyor belt or by a clamp that can be transferred between each station, its control and drive are simpler and more convenient, reducing the learning cost of operators and improving the convenience of maintenance and adjustment. Example

[0062] As another embodiment of the present invention, this embodiment makes the following improvements based on embodiment one.

[0063] In this embodiment, as Figure 1 As shown, the material preparation section 2 also includes a shape adjustment station 22, which is used to adjust the shape of the battery cell from the puncture station 21 so that it can smoothly reach the cutting station 23 and complete the cutting of the punctured part.

[0064] Specifically, the piercing station 21 and the cutting station 23 are arranged sequentially along the first direction. The shape adjustment station 22 is located between the piercing station 21 and the cutting station 23 along the first direction. After receiving the battery cell from the piercing station 21, the shape adjustment station 22 fixes the battery cell and then adjusts it to a shape that is easy to cut by horizontal rotation, vertical flipping, twisting and other actions. Due to the addition of the shape adjustment station 22, the dwell time of the battery cell in the material preparation section 2 is extended, and the battery cell shape adjustment process is conducive to the operator's observation of the battery cell appearance. In order to further improve the ease of use of the secondary sealing machine, an inspection station is also formed on the secondary sealing machine. The inspection station is formed on the side of the first work area A away from the second work area B, between the loading station 11 and the unloading station 5, and is directly opposite the shape adjustment station 22 along the second direction. The inspection station is equipped with a transparent observation window, so that the operator can directly observe the shape adjustment process of the battery cell, which is convenient for timely detection of battery cell defects and improves the production yield.

[0065] To further improve the efficiency of the secondary sealing machine, the shape adjustment station 22 also includes a third conveying component 8 arranged along the second direction. The shape adjustment station 22 is located at one end of the third conveying component 8, and the other end of the third conveying component 8 is located near the inspection station. Correspondingly, an openable and closable door is set at the inspection station. When the operator finds a defect in the battery cell or observes a possible defect that needs further confirmation, the operator can control the secondary sealing machine to convey the battery cell located at the shape adjustment station 22 to the inspection station through the third conveying component 8. This allows for close inspection of the battery cell, and if a defect is confirmed, it can be directly removed. Moreover, the inspection station, the loading station 11, and the unloading station 5 are located on the same side of the secondary sealing machine, and the inspection station is located between the loading station 11 and the unloading station 5. During the movement between the loading station 11 and the unloading station 5, the operator will frequently pass by the inspection station, eliminating the need for dedicated inspection of the battery cell. This improves the operator's efficiency while further reducing the operator's workload.
