[0001] This application relates to the field of solar photovoltaic packaging technology, and in particular to an automatic battery cell packaging equipment and a battery cell processing system. Background Technology

[0002] With the development of the solar photovoltaic industry, in order to improve conversion efficiency, the size of solar cells is getting larger and thinner, making them extremely fragile. During the transfer and handling process, the solar cells are easily damaged, which places high demands on the packaging of solar cells.

[0003] In related technologies, when defective solar cells are discovered during the packaging process, they cannot be traced back to their source, making it impossible to identify the production line and machine where the defective solar cell originated. This necessitates checking each production line individually, severely impacting the efficiency and yield of solar cell packaging. Utility Model Content

Therefore, during the automatic battery cell packaging process, if the detection mechanism detects defective cells, the information displayed on the display mechanism can be used for traceability, identifying the production line and machine where the defective cell was found, enabling timely repair and maintenance, thus improving the efficiency and yield of battery cell packaging.

Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] In this application, the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0038] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0039] Furthermore, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; 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, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0040] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0041] With the vigorous development of the solar photovoltaic industry, in order to improve the photoelectric conversion efficiency of solar cells, the size of solar cells is becoming larger and thinner. However, this development brings challenges to the transportation of solar cells, meaning that they are more susceptible to damage during transportation.

[0042] Packaging solar cells can effectively solve this problem. Automated packaging machines are widely used because they can automatically package solar cells after processing for transportation or storage, improving the safety and reliability of solar cells during transportation and storage, thereby avoiding damage during transport.

[0043] In related technologies, when defective solar cells are discovered during the packaging process, it is impossible to trace their origin, making it impossible to identify the production line and machine where the defective solar cell originated. This necessitates checking each production line individually to locate the defective solar cell and perform repairs, which severely impacts the efficiency and yield of solar cell packaging.

[0044] In view of this, this application discloses an automatic battery cell packaging device and a battery cell processing system. By providing an identification module on the battery cell-loaded cassette, when the cassette is transported to the cassette separation mechanism via a transport mechanism, the separation components of the cassette separation mechanism separate the battery cells from the cassette. Simultaneously, a first reader in the cassette separation mechanism reads the information carried by the identification module on the cassette and sends it to a control module. The separated battery cells are then inspected for appearance by a detection mechanism located downstream of the cassette separation mechanism, and subsequently packaged by a packaging mechanism. A display mechanism electrically connected to the control module can display the information carried by the identification module when the detection mechanism detects an abnormality in the appearance of the battery cells. This allows the first reader to read the information carried by the identification module on the battery cell-loaded cassette and display it on the display mechanism. Therefore, during the automatic battery cell packaging process, if the detection mechanism detects defective cells, the information displayed on the display mechanism can be used for traceability, enabling quick identification of the production line and machine where the defective cells are located for timely repair and maintenance, thereby improving the efficiency and yield of battery cell packaging.

[0045] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0046] Please see Figure 1 , Figure 1This is a schematic diagram of an automatic battery cell packaging device disclosed in an embodiment of this application. The automatic battery cell packaging device 100 includes a transport mechanism 1, a cassette separation mechanism 2, a detection mechanism 3, a packaging mechanism 4, and a display mechanism (not shown in the figure). The transport mechanism 1 is configured to transport a cassette 6 containing battery cells 5, and the cassette 6 is provided with an identification module 61. The cassette separation mechanism 2 is located downstream of the transport mechanism 1. The cassette separation mechanism 2 includes a separation component 21 and a first reader 22. The separation component 21 is configured to separate the battery cells 5 from the cassette 6. The first reader 22 is electrically connected to the control module (not shown in the figure) of the battery cell processing system 200. The first reader 22 is configured to read the information carried by the identification module 61 on the cassette 6 and send it to the control module. The detection mechanism 3 is located downstream of the cassette separation mechanism 2. The detection mechanism 3 is configured to detect the appearance of the battery cells 5. The packaging mechanism 4 is located downstream of the detection mechanism 3. The packaging mechanism 4 is configured to package the detected battery cells 5. The display mechanism is electrically connected to the control module. The display mechanism is configured to display the information carried by the identification module 61 when the detection mechanism 3 detects an abnormality in the appearance of the battery cell 5.

[0047] The automatic battery cell packaging equipment 100 disclosed in this application, through the cooperation of a transport mechanism 1, a box separation mechanism 2, an inspection mechanism 3, and a packaging mechanism 4, can transport a box 6 containing battery cells 5 to the box separation mechanism 2. The separation component 21 separates the battery cells 5 from the box 6. The inspection mechanism 3 performs appearance inspection on the battery cells 5, and the packaging mechanism 4 packages the inspected battery cells 5. This enables automated packaging of battery cells 5, thereby improving the packaging speed and accuracy of battery cells 5.

[0048] Secondly, the material box 6 is equipped with an identification module 61, which can be read by the first reader 22 and sent to the control module. When the detection mechanism 3 detects that the battery cell 5 is a defective cell, the control module can display the information carried by the identification module 61 of the defective cell through the display mechanism, so that the staff can quickly trace the defective cell to the production machine and production line, thereby repairing the production machine and production line of the defective cell, which can improve the packaging efficiency and yield of the battery cell 5.

[0049] In addition, the inspection agency 3 can inspect the appearance of the battery cell 5 during the automatic packaging process, thereby promptly identifying battery cells 5 with appearance defects such as scratches and damage, so as to avoid packaging battery cells 5 with appearance defects and improve the packaging yield of battery cells 5.

[0050] It is understood that the aforementioned battery cell 5 can be multiple battery cells 5 stacked sequentially. The battery cell 5 can be a square battery cell 5 or a rectangular battery cell 5. This embodiment does not make specific limitations in this regard.

[0051] It is understood that if the identification module 61 can be a QR code, then the corresponding first reader 22 is a QR code scanner; or, if the identification module 61 can be a radio frequency identification chip, then the corresponding first reader 22 is a radio frequency identification device. This embodiment does not make specific limitations in this regard.

[0052] It is understandable that the information carried by the identification module 61 may include the quantity, quality, production machine, production line, production workshop, production batch, production date, etc. of the battery cells 5.

[0053] In order to promptly inform staff and handle defective cells when the testing agency 3 detects them as defective, the automatic cell collection device 100 can also be equipped with an alarm device (not shown in the figure). This alarm device can be a buzzer or a signal light, etc., and this embodiment does not make specific limitations on it.

[0054] It is understandable that defective chips can be handled by manually picking them out when an alarm signal is received, or by using a robotic arm to remove them and collect them separately. This embodiment does not impose any specific limitations.

[0055] It is understood that the alarm device and display mechanism mentioned above can be separate or integrated, and this embodiment does not make specific limitations on this.

[0056] Optionally, the separation component 21 may include a gripper-type robotic arm or a suction cup-type robotic arm, which can remove the battery cell 5 from the material box 6 and separate the battery cell 5 from the material box 6. This embodiment does not specifically limit this.

[0057] Optionally, the aforementioned inspection mechanism 3 can be an AOI (Automated Optical Inspection) camera or a laser scanning device. Taking an AOI camera as an example, the number of AOI cameras can be nine, respectively positioned on the four sides and four corners of the battery cell 5, and spaced apart above the battery cell 5. This allows for a comprehensive inspection of the appearance of the battery cell 5, eliminating blind spots and ensuring the comprehensiveness of the inspection by the inspection mechanism 3. Furthermore, simultaneous inspection by nine AOI cameras can shorten the inspection time, thereby improving the efficiency of the battery cell 5 packaging.

[0058] Optionally, the above-mentioned display mechanism may be a liquid crystal display screen or an organic light-emitting diode display screen, etc., and this embodiment does not impose specific limitations.

[0059] Optionally, the transport of the battery cell 5 between the transport mechanism 1, the material box separation mechanism 2, the detection mechanism 3 and the packaging mechanism 4 can be carried out by a robotic arm gripping or by a conveyor belt. This application will use the example of transporting the battery cell 5 between the various mechanisms by a robotic arm gripping as an example.

[0060] Optionally, please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the transportation mechanism disclosed in the embodiments of this application. Figure 3 This is a schematic diagram of the structure of multiple material box separation mechanisms and multiple shaping mechanisms disclosed in the embodiments of this application. The automatic battery cell packaging equipment 100 also includes a shaping mechanism 7, which is located downstream of the material box separation mechanism 2 and upstream of the detection mechanism 3. The shaping mechanism 7 is configured to shape the battery cells 5 separated by the material box separation mechanism 2. By setting the shaping mechanism 7 between the material box separation mechanism 2 and the detection mechanism 3 to shape the battery cells 5, the battery cells 5 can enter the detection mechanism 3 in a standard shape and posture, which helps the detection mechanism 3 to more accurately detect the appearance of the battery cells 5 and avoids the situation where the irregular shape of the battery cells 5 affects the detection accuracy of the detection mechanism 3.

[0061] In addition, by shaping the battery cell 5 in the shaping mechanism 7, the battery cell 5 can be smoothly transferred between the various mechanisms of the automatic battery cell packing device 100, avoiding the occurrence of collisions or jamming between the battery cell 5 and the mechanism due to its irregular shape, thereby improving the stability and reliability of the operation of the automatic battery cell packing device 100.

[0062] It is understandable that the aforementioned shaping mechanism 7 can be a pneumatic shaping fixture, using air pressure to drive the opening and closing of the fixture. Thus, when the battery cell 5 enters the fixture, the fixture clamps and shapes the battery cell 5 according to a preset shape. Of course, as another example, the shaping mechanism 7 can also be a mechanical fixture. For instance, a fixture with a specific shape can be used to place the battery cell 5 into the fixture, and mechanical force can be used to straighten the battery cell 5.

[0063] For some embodiments, please refer to Figure 3 Both the material box separation mechanism 2 and the shaping mechanism 7 can include multiple units. The multiple material box separation mechanisms 2 are spaced apart, and the multiple shaping mechanisms 7 are located on different sides of the detection mechanism 3, corresponding one-to-one with the multiple material box separation mechanisms 2. By setting multiple material box separation mechanisms 2 and multiple shaping mechanisms 7, the efficiency of separating the battery cell 5 from the material box 6 and shaping the battery cell 5 can be improved, thereby increasing the efficiency of the automatic battery cell packaging equipment 100 in packaging the battery cell 5.

[0064] Understandably, when both the material box separation mechanism 2 and the shaping mechanism 7 include multiple units, since a robotic arm is installed between the detection mechanism 3 and the shaping mechanism 7 to transport the shaped battery cells 5 to the detection mechanism 3 for detection, a first detection area and a second detection area can be set up to avoid interference between the robotic arm and the detection mechanism 3. Both the first and second detection areas can be equipped with this detection mechanism. For example, the first detection area can be equipped with three AOI cameras, located on the two sides of the first detection area not close to the robotic arm and spaced apart above the battery cells 5. The remaining six AOI cameras are located on the other two sides and four corners of the second detection area. This avoids interference between the AOI cameras and the robotic arm, thus preventing disruption to the normal operation of the detection mechanism 3.

[0065] Alternatively, please refer to the following: Figure 2 The transport mechanism 1 includes a first transport layer 11, a second transport layer 12, and a third transport layer 13 arranged sequentially from top to bottom along the height direction of the transport mechanism 1. The first transport layer 11 is configured to dock with the packaging mechanism 4 to transport packaged battery cells 5. The second transport layer 12 is configured to dock with the box separation mechanism 2 to transport boxes 6 containing battery cells 5 to the box separation mechanism 2. The third transport layer 13 docks with the box separation mechanism 2 to transport boxes 6 separated from battery cells 5.

[0066] First, the first transport layer 11 is specifically responsible for transporting the packaged battery cells 5, making the transport process of the packaged battery cells 5 clear and independent. The packaged battery cells 5 can be directly transported to subsequent processes or stored. It can also prevent the packaged battery cells 5 from being confused or colliding with other materials (such as unpackaged battery cells 5 or material boxes 6), thereby improving the production efficiency of the automatic battery cell packaging equipment 100.

[0067] Secondly, the second transport layer 12 is responsible for transporting the box 6 containing the battery cells 5 to the box separation mechanism 2. This ensures that the box 6 containing the battery cells 5 can arrive at the box separation mechanism 2 accurately and in a timely manner, ensuring the stable operation of the automatic battery cell collection equipment 100, thereby improving the production efficiency of the automatic battery cell collection equipment 100.

[0068] In addition, the third transport layer 13 is responsible for transporting the empty material box 6 after it is separated from the battery cell 5. This allows the empty material box 6 to be quickly moved away, avoiding the space occupied by the empty material box 6 and its impact on the entire automatic battery cell 5 packaging process. By using three transport layers to transport different materials, and by arranging the three transport layers sequentially along the height of the transport mechanism 1, the overall space occupied by the transport mechanism 1 can be reduced, thereby reducing the space occupied by the automatic battery cell packaging equipment 100 and improving the space utilization rate of the battery cell 5 production workshop.

[0069] It is understood that the first transport layer 11, the second transport layer 12 and the third transport layer 13 mentioned above can be in the form of conveyor belts or rollers, and this embodiment does not specifically limit them.

[0070] It is understood that the first transport layer 11, the second transport layer 12 and the third transport layer 13 are independent, thereby avoiding the mixing of different materials.

[0071] In some embodiments, please refer to Figure 2 Along the height direction of the transport mechanism 1, the second transport layer 12 corresponds to the material box separation mechanism 2. That is, the second transport layer 12 and the material box separation mechanism 2 are located at the same height. This allows the material box 6 carrying the battery cells 5 transported by the second transport layer 12 to be conveniently transferred to the material box separation mechanism 2 for separation of the material box 6 and the battery cells 5, thereby improving the production efficiency of the automatic battery cell packaging equipment 100.

[0072] Understandably, since the material box separation mechanism 2 and the third transport layer 13 are not at the same height, in order to transport the empty material box 6 between the material box separation mechanism 2 and the third transport layer 13, the automatic battery cell packing equipment 100 also includes a first lifting component 23. This first lifting component 23 is connected to both the material box separation mechanism 2 and the third transport layer 13, and is configured to transport the empty material box 6 between them. By setting up the first lifting component 23, it is possible to ensure that the empty material box 6 is transferred between the material box separation mechanism 2 and the third transport layer 13 in a timely and accurate manner, which helps to ensure the efficient operation of the entire automatic battery cell packing process.

[0073] It is understood that the first lifting component 23 mentioned above includes a driving component and a platform. The platform is driven to move along the height direction of the transport mechanism 1 by the driving component to realize the transport of the empty material box 6. The driving component can be a hydraulic cylinder or an electric lead screw, etc., and this embodiment does not make specific limitations on it.

[0074] In some embodiments, please refer to Figure 4 The packaging mechanism 4 includes a pad assembly 41, a film sleeve assembly 42, and a packaging box assembly 43 arranged sequentially. The pad assembly 41 is located downstream of the detection mechanism 3 and is configured to place a pad on the detected battery cell 5. The film sleeve assembly 42 is configured to sleeve a film onto the battery cell 5 with the pad. The packaging box assembly 43 is configured to package the sleeved battery cell 5 into a packaging box.

[0075] First, by using the pad assembly assembly 41, a pad can be placed on the inspected battery cell 5, which can prevent the battery cell 5 from being damaged by mechanical damage such as scratches or collisions during the subsequent packaging process, thereby improving the yield of battery cell 5 packaging.

[0076] Secondly, the film-covering assembly 42 can cover the battery cell 5 with the pad, which can effectively isolate external dust and moisture, thereby avoiding corrosion and other effects on the battery cell 5, and thus extending the shelf life of the battery cell 5.

[0077] Furthermore, the packaging box assembly component 43 allows the coated solar cells 5 to be packaged into the box, further enhancing the protection of the solar cells 5 and preventing damage during transportation due to vibration, compression, or other factors. Simultaneously, the packaging box facilitates the centralized transportation and storage of multiple solar cells 5, improving logistics and warehousing efficiency.

[0078] It is understood that the aforementioned pad assembly 41 includes a sulfur-free paper assembly 411 and a hollow plate assembly 412. Sulfur may chemically react with certain chemical components of the battery cell 5, thereby corroding the battery cell 5 and affecting its chemical performance. Therefore, sulfur-free paper is tightly attached to the upper and lower end faces of the battery cell 5 using the sulfur-free paper assembly 411, thus preventing the battery cell 5 from contacting sulfur-containing substances in the external environment and causing corrosion. Additionally, a hollow plate is attached to the outer surface of the sulfur-free paper using the hollow plate assembly 412. The hollow plate is a new type of hollow plastic packaging material with a certain strength and rigidity, thus providing structural support for the battery cell 5 and preventing deformation under external pressure.

[0079] It is understood that the sulfur-free paper assembly 411, hollow board assembly 412, film sleeve assembly 42 and packaging box assembly 43 mentioned above may include gripper-type robotic arms or suction cup-type robotic arms, and this embodiment does not specifically limit them.

[0080] Optionally, an upstream shaping component identical to the shaping mechanism 7 is provided for the packaging box assembly assembly 43. This shaping component is configured to shape the coated battery cell 5 before assembling the packaging box. By providing the shaping component, it can be ensured that the battery cell 5 is placed neatly in the packaging box, thereby avoiding damage to the packaging box caused by the irregular shape of the battery cell 5.

[0081] In some embodiments, please refer to Figure 4The packaging mechanism 4 also includes a pad feeding assembly 44, a film feeding assembly 45, and a packaging box feeding assembly 46. The pad feeding assembly 44 is located upstream of the pad assembly assembly 41 and is used to provide pads to the pad assembly assembly 41. The film feeding assembly 45 is located upstream of the film sleeve assembly 42 and is configured to provide film to the film sleeve assembly 42. The packaging box feeding assembly 46 is located upstream of the packaging box assembly 43 and is configured to provide packaging boxes to the packaging box assembly 43. By setting up the pad feeding assembly 44, the film feeding assembly 45, and the packaging box feeding assembly 46, the pads, film, and packaging boxes can be continuously and stably provided, thereby ensuring the smooth operation of the automatic battery cell packing equipment 100 and helping to improve the overall efficiency of the automatic battery cell packing.

[0082] Understandably, in order to better enable the pads of the pad feeding assembly 44 to provide pads to the pad assembly assembly 41 in a specific direction and position to meet the requirements of the pad assembly assembly 41, a robot and a paper roller can be set between the pad feeding assembly 44 and the pad assembly assembly 41. The robot grabs the pads and feeds them into the paper roller, and the pads are fed into the pad assembly assembly 41 for pad assembly.

[0083] It is understood that the film-shrinking assembly 42 can be a heat-shrink film-shrinking assembly, specifically, the heat-shrink film on the battery cell 5 is heated by hot air or infrared rays, so that the film can tightly wrap the battery cell 5 and the pad. Of course, as other examples, the film-shrinking assembly 42 can also be a vacuum film-shrinking assembly, etc.

[0084] Optionally, please refer to Figure 4 An upstream area for film covering assembly 42 is provided for film covering waiting area 421. The solar cell 5 with a pad first arrives at film covering waiting area 421. A conveyor belt is provided between film covering waiting area 421 and film covering assembly 42. Film feeding assembly 45 first transports the film to film covering assembly 42. The conveyor belt then transports the solar cell 5 with the pad from film covering waiting area 421 to film covering assembly 42. The film covering assembly 42 then tightly wraps the film around the solar cell 5 and the pad. Using a conveyor belt to transport the solar cell 5 with the pad to the film avoids the conveying device from entering the film and damaging it, or the conveying device being encased in the film.

[0085] It is understandable that the above-mentioned film-covering waiting area 421 is located upstream of the packaging box assembly component 43. After the battery cell 5 with the pad is covered with film, it needs to return to the film-covering waiting area 421 before being transferred to the packaging box assembly component 43 for packaging box assembly.

[0086] It is understood that the aforementioned packaging box can be a cardboard box, a foam box, or a hollow board packaging box, and this embodiment does not specifically limit it.

[0087] In some embodiments, please refer to Figure 4 The automatic battery cell packaging equipment 100 also includes a labeling mechanism 8, which is located downstream of the packaging box assembly 43. The labeling mechanism 8 is electrically connected to the control module and is configured to generate a label corresponding to the information carried by the identification module 61 and affix it to the packaging box of the packaged battery cells 5.

[0088] The labeling mechanism 8 generates labels corresponding to the information carried by the identification module 61, meaning that each label on the packaging box contains information about the product. Throughout the entire production and transportation process of the battery cell 5, all information about the battery cell 5 is affixed to the packaging box through labeling. When a problem occurs with the product, such as when the performance of the battery cell 5 is found to be substandard in the downstream usage stage or during quality inspection, the labels on the packaging box can be used to quickly trace back to each stage of the production process, thereby accurately pinpointing the root cause of the problem.

[0089] Optionally, please refer to Figure 5 , Figure 5 This is another structural schematic diagram of the automatic battery cell packaging equipment disclosed in this application. The automatic battery cell packaging equipment 100 also includes a feeding mechanism 9, which is located downstream of the packaging mechanism 4. The packaging mechanism 4 connects to the first transport layer 11 through the feeding mechanism 9 to transport the packaged battery cells 5 to the first transport layer 11. By positioning the feeding mechanism 9 downstream of the packaging mechanism 4 and connecting it to the first transport layer 11, the process from packaging to transporting the battery cells 5 can be seamlessly connected, thereby reducing downtime caused by process transitions and improving the efficiency of automatic battery cell packaging.

[0090] In some embodiments, please refer to Figure 5 , combined Figure 6 , Figure 6 yes Figure 5 The top view shows the unloading mechanism 9, which includes a connecting assembly 91, a temporary storage assembly 92, and an unloading assembly 93. The connecting assembly 91 is located downstream of the packaging mechanism 4, while the temporary storage assembly 92 and the unloading assembly 93 are located on both sides of the connecting assembly 91 and connected to it. The connecting assembly 91 is used to receive packaged battery cells 5, the temporary storage assembly 92 is used to temporarily store the packaged battery cells 5, and the unloading assembly 93 is used to transport the packaged battery cells 5 to the first transport layer 11.

[0091] By setting up the connecting component 91, the packaged materials can be prevented from piling up at the packaging mechanism 4, which would affect the normal packaging of the packaging mechanism 4. Furthermore, the battery cells 5 at the connecting component 91 can be flexibly selected to be directly transported to the first transport layer 11 or temporarily stored first.

[0092] By setting up a temporary storage component 92 to temporarily store the packaged battery cells 5, when the unloading component 93 experiences a brief malfunction or the receiving capacity of the first transport layer 11 is temporarily insufficient, the temporary storage component 92 can store a certain number of battery cells 5, preventing the battery cells 5 from piling up on the automatic battery cell receiving device 100 and ensuring that the entire automatic battery cell receiving device 100 will not stop operating due to local problems.

[0093] It is understood that the aforementioned connecting component 91 and temporary storage component 92 can specifically be placement platforms. The connecting component 91 docks with the packaging mechanism 4 via a conveyor belt or a robotic arm, and the temporary storage component 92 can also dock with the connecting component 91 via a conveyor belt or a robotic arm. For example, when the packaged battery cell 5 is transported to the connecting component 91, if the receiving capacity of the first transport layer 11 is sufficient, the packaged battery cell 5 can be transported to the first transport layer 11 via the unloading component 93 via a conveyor belt or a robotic arm. If the receiving capacity of the first transport layer 11 is insufficient, the packaged battery cell 5 can be transported to the temporary storage component 92 via a conveyor belt or a robotic arm for temporary storage. When the receiving capacity of the first transport layer 11 is sufficient, the packaged battery cell 5 is first transported to the connecting component 91 via a conveyor belt or a robotic arm, and then transported to the first transport layer 11 via the unloading component 93.

[0094] It is understood that the above-mentioned feeding component 93 has the same structure as the first transport layer 11, and this embodiment will not elaborate on it.

[0095] Alternatively, please continue reading Figure 5 In order to avoid other components of the automatic battery cell packaging equipment 100, the unloading connecting component 91, the unloading component 93 and the first transport layer 11 are not at the same height along the height direction of the transport mechanism 1. The unloading component 93 is set above the connecting component 91 and the first transport layer 11. A second lifting component 911 is provided at the connecting component 91 and at the component near the first transport layer 11. The packaged battery cells 5 can be transported from the connecting component 91 to the first transport layer 11 through the second lifting component 911.

[0096] It is understood that the second lifting component 911 has the same structure as the first lifting component 23, and this embodiment will not elaborate further on this.

[0097] Please see Figure 7 , Figure 7This is a schematic diagram of the structure of the battery cell processing system disclosed in the embodiments of this application. Secondly, this application also discloses a battery cell processing system 200, including a control module (not shown in the figure) and an automatic battery cell packaging device 100 as described in the first aspect above. The control module is electrically connected to the automatic battery cell packaging device 100. By setting the control module to be electrically connected to the automatic battery cell packaging device 5, the information carried by the identification module 61 of the material box 6 can be read, retrieved, and displayed during the automatic battery cell packaging process. On the one hand, when the inspection mechanism 3 detects defective cells, the information carried by the identification module 61 can be used to accurately trace the defective cell back to the production machine. On the other hand, the labeling mechanism 8 can generate corresponding labels from the information carried by the identification module 61 and affix them to the packaging box of the battery cell 5 for easy viewing.

[0098] The automatic battery cell packing device 100 in this application embodiment can have the same structure as any of the automatic battery cell packing devices 100 in the above embodiments and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments. This application embodiment will not be repeated here.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
