Technical Field

[0001] This application relates to the field of solar cell technology, and in particular to a solar cell transfer method and a solar cell transport device. Background Technology

[0002] Fossil fuels cause air pollution and have limited reserves, while solar energy has advantages such as being clean, pollution-free, and abundant. Therefore, solar energy is gradually becoming the core clean energy source to replace fossil fuels. Due to the excellent photoelectric conversion efficiency of solar cells, solar cells have become the focus of development for clean energy utilization.

[0003] One important factor affecting the proportion of solar energy in energy utilization is the photoelectric conversion efficiency of solar cells. In order to improve the photoelectric conversion efficiency of solar cells, optimizing and improving the manufacturing process and structural design of solar cells based on the performance of different solar cells in applications, such as light absorption capacity, lifespan, and failure rate, is a basic approach to improving the performance of solar cells.

[0004] However, during the production of solar cells, problems such as loss of process flow information and disordered information records can easily occur when solar cells are transferred through multiple processes, resulting in poor process traceability of solar cells. Summary of the Invention

[0005] This application provides a method for transferring solar cells and a cell transfer device, which at least helps to ensure that the actual production output of solar cells matches the production plan, and to achieve traceability of process flow information at the cell level.

[0006] This application provides a method for the circulation of solar cells, comprising: reporting the basket code of a basket carrier to a software system for the software system to determine the maximum cell capacity of the basket carrier; receiving the maximum cell capacity and work order data issued by the software system; determining the number of cells to be unloaded from the basket carrier based on the work order data and the maximum cell capacity; loading the basket carrier with cells according to the number of cells to be unloaded, and recording the circulation information of each cell.

[0007] In addition, the work order data includes batch name and batch feeding quantity. Determining the number of battery cells to be fed into the flower basket carrier based on the work order data and the maximum battery cell capacity includes: determining the current feeding batch and the number of battery cells to be fed into the current feeding batch based on the work order data; if the maximum battery cell capacity is greater than or equal to the number of battery cells to be fed into the batch, using the number of battery cells to be fed into the batch as the number of battery cells to be fed into the batch; if the maximum battery cell capacity is less than the number of battery cells to be fed into the batch, using the maximum battery cell capacity as the number of battery cells to be fed into the batch.

[0008] In addition, determining the current batch and the number of cells to be fed in the current batch based on the work order data includes: determining the batch name and the number of cells already fed in the current batch based on pre-cached historical feeding data; and determining the number of cells to be fed in the current batch based on the number of cells already fed in the current batch and the batch feeding quantity corresponding to the current batch.

[0009] In addition, after determining the number of battery cells to be fed into the flower basket carrier, the method further includes updating the historical feeding data based on the number of battery cells to be fed into the flower basket carrier.

[0010] In addition, the work order data includes the set capacity of the flower basket carrier, and determining the number of battery cells to be unloaded by the flower basket carrier includes: using the set capacity as the number of battery cells to be unloaded by the flower basket carrier.

[0011] In addition, the set capacity is determined in the following way: based on the pre-cached historical feeding records, the current feeding batch and the number of battery cells to be fed in the current feeding batch are determined; if the maximum battery cell capacity is greater than or equal to the number of battery cells to be fed, the number of battery cells to be fed is used as the set capacity; if the maximum battery cell capacity is less than the number of battery cells to be fed, the maximum battery cell capacity is used as the set capacity.

[0012] In addition, the step of reporting the flower basket code of the flower basket carrier to the software system includes: monitoring the location of each flower basket carrier in each transmission track; sequentially acquiring and reporting the flower basket code of each flower basket carrier according to the arrival time of each flower basket carrier to the unloading position; and determining the number of unloaded battery cells of the flower basket carrier includes: determining the number of unloaded battery cells of each flower basket carrier one by one according to the arrival time corresponding to each flower basket carrier.

[0013] In addition, the battery cell includes a battery cell marking code. The process of recording the circulation information of each battery cell includes: parsing the current battery cell's code using a decoder to obtain the battery cell marking code of the current battery cell; determining the position information of the current battery cell in the flower basket carrier based on the battery cell circulation record; and associating and storing the flower basket code and the position information of the flower basket carrier with the battery cell marking code.

[0014] In addition, after recording the flow information of each battery cell, the method further includes: reporting the battery cell unloading data of the flower basket carrier to the software system. The battery cell unloading data includes the flower basket code of the flower basket carrier, the maximum battery cell capacity, the number of unloaded battery cells, the battery cell marking code of each battery cell, and the position information of each battery cell.

[0015] Accordingly, this application also provides a solar cell transfer device, including: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the solar cell transfer method as described above.

[0016] The technical solution provided in this application has at least the following advantages:

[0017] In the solar cell transfer scheme provided in this application embodiment, after the basket carrier used for solar cell unloading arrives at the unloading position, the basket carrier's basket code is reported to the software system, and the maximum cell capacity of the basket carrier and work order data are received from the software system. Then, the cell transfer device determines the number of cells to be unloaded from the basket carrier based on the obtained work order data and the maximum cell capacity of the basket carrier, and transfers the cells to the basket carrier according to the determined number of cells to be unloaded. While loading the cells into the basket carrier, the transfer information of each cell transferred to the basket carrier is recorded. During the cell loading process, the cell conveying equipment determines the number of cells to be loaded into each basket carrier based on the work order data and the maximum cell capacity of the basket carrier. This ensures that the number of cells loaded into each basket carrier is clear and accurate, and the final loading quantity matches the quantity planned in the work order data, improving the accuracy of cell loading. During the loading of cells into the basket carriers, the flow information of each cell is recorded, facilitating traceability of the cell-level process flow information. This allows for accurate and effective optimization of the cell manufacturing process based on the cell's process information. Attached Figure Description

[0018] One or more embodiments are illustrated by way of example with reference to the accompanying drawings. These illustrations do not constitute a limitation on the embodiments, and unless otherwise stated, the figures in the drawings are not to be limited by scale.

[0021] Figure 3 This is a schematic diagram of a battery cell transmission device provided in another embodiment of this application. Detailed Implementation

[0022] As the background technology shows, the optimization and improvement of solar cell design and manufacturing depends on the traceability of cell process information. Since it is difficult to accurately control the cell feeding process, the cell process is prone to problems such as loss of process information and chaotic process flow information records during the process flow, which makes it difficult to achieve cell-level process information traceability.

[0023] One embodiment of this application provides a method for the transfer of solar cell wafers. During the solar cell unloading process, the basket code of the basket carrier arriving at the unloading location is reported, and the maximum cell capacity of the basket carrier and work order data are received from the software system. Then, based on the maximum cell capacity and work order data, the number of cells to be unloaded by the basket carrier is determined, and cells are loaded onto the basket carrier according to this number. Accurate control is exercised over the number of cells loaded into each basket carrier, ensuring that the final unloaded number of cells matches the quantity planned in the work order data. This improves the accuracy of cell unloading and avoids confusion in the cell transfer records caused by inaccurate unloading. During the cell unloading process, the transfer information of each cell is recorded separately, facilitating traceability of cell-level process transfer information and subsequent optimization of the cell manufacturing process based on the cell's process information.

[0024] The embodiments of this application will now be described in detail with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the embodiments of this application to facilitate a better understanding of the application. However, the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0025] One embodiment of this application provides a method for transferring solar cells, which is applied to solar cell transfer equipment, such as a cell guide machine, a solar cell conveyor belt, etc. The solar cell transfer process can be referred to... Figure 1 This includes, but is not limited to, the following steps:

[0026] Step 101: Report the flower basket code of the flower basket vehicle to the software system.

[0027] During the transfer of solar cells, the cell transport equipment monitors the transport track it is connected to. Once the basket carrier on the track reaches the preset unloading position, it obtains the basket code of the arriving carrier. This basket code is then reported to the software system, which uses it to query pre-stored carrier information, including basket type, basket code, and maximum cell capacity, to determine the maximum cell capacity of the basket carrier.

[0028] For example, a radio frequency identification (RFID) chip is pre-installed in the basket carrier, and corresponding identification data is written into the RFID chip. This identification data may include the basket carrier's operational scope, carrier type, capacity, etc., and is pre-stored in the software system. The operational scope is determined based on the various processes involved in the battery cell transfer using the basket carrier. After the basket carrier reaches the unloading position, the battery cell transfer device uses sensors to obtain the corresponding code from the RFID chip in the basket carrier, which is then reported to the software system as the basket code. Upon receiving the basket code, the software system queries the identification data within the software system to obtain information such as the basket carrier type and maximum battery cell capacity. In specific applications, other technologies can also be used to identify the basket carrier, such as setting a QR code on the surface of the basket carrier or installing an identity broadcasting circuit. This application embodiment does not limit the identification method or the specific type of the basket code.

[0029] It's worth noting that the cell transfer equipment and software system can be built using a client / server architecture. This means the cell transfer equipment acts as the client, while the software system acts as the server. The software system and the cell transfer equipment communicate via polling, ensuring accurate cell transfer while reducing the manufacturing cost and complexity of the cell transfer equipment. Furthermore, the software system can be directly integrated into the cell transfer equipment, operating as an independent system outside the equipment's control system. This allows for information exchange via inter-system protocols, integrating both systems within the cell transfer equipment. This improves the fault tolerance of the cell transfer equipment and prevents communication failures or anomalies between the cell transfer equipment and external systems from affecting cell transfer.

[0030] Step 102: Receive the maximum cell capacity and work order data issued by the software system.

[0031] The battery cell conveying equipment reports the basket code of the basket carrier that arrives at the unloading position to the software system. The software system first queries the work order of the current battery cell circulation plan of the battery cell conveying equipment to determine the work order data corresponding to the current battery cell circulation plan.

[0032] The work order data issued by the software system can include: work order name and work order material quantity. The work order name is the code or identifier of the currently executed work order, and the work order material quantity is the planned quantity of solar cells to be delivered. In addition, the work order data can also include batch name and batch material quantity. The batch name is the code or identifier of each material delivery batch within the work order, and the batch material quantity is the quantity of solar cells delivered in each material delivery batch.

[0033] In addition, the software system will query pre-stored identification information based on the received basket code, or parse the basket code using a preset algorithm to obtain information such as the basket carrier type and maximum battery cell capacity. After determining the work order data corresponding to the current battery cell circulation plan and the maximum battery cell capacity of the basket carrier, the system will send the work order data and the maximum battery cell capacity of the basket carrier to the battery cell transmission equipment. The battery cell transmission equipment will receive the data messages sent by the software system through a preset port or preset communication protocol, and obtain the maximum battery cell capacity of the basket carrier and the work order data sent by the software system by parsing the data messages.

[0034] Step 103: Determine the number of battery cells to be unloaded by the flower basket carrier based on the work order data and the maximum battery cell capacity.

[0035] During the cell transfer process, the cell transfer equipment can cache the cell transfer records. Therefore, after obtaining the work order data and the maximum cell capacity of the basket carrier issued by the software system, the current cell unloading progress is determined based on the work order data and cell transfer records. Based on the current cell unloading progress and the maximum cell capacity of the basket carrier, the number of cells to be unloaded by the basket carrier is determined.

[0036] In some embodiments, the work order data includes a batch name and a batch quantity. Determining the number of battery cells to be unloaded by the basket carrier based on the work order data and the maximum battery cell capacity includes: determining the current unloading batch and the number of battery cells to be unloaded in the current unloading batch based on the work order data; if the maximum battery cell capacity is greater than or equal to the number of battery cells to be unloaded, using the number of battery cells to be unloaded as the number of battery cells to be unloaded; if the maximum battery cell capacity is less than the number of battery cells to be unloaded, using the maximum battery cell capacity as the number of battery cells to be unloaded.

[0037] In determining the number of solar cells to be unloaded by the solar cell transfer equipment, the process first involves determining the unloading progress of the current work order based on work order data and solar cell transfer records, and obtaining the current unloading batch and the number of solar cells to be unloaded in the current unloading batch. After obtaining the number of solar cells to be unloaded, the maximum solar cell capacity of the solar cell transfer equipment is compared with the number of solar cells to be unloaded in the current unloading batch. If the maximum solar cell capacity is greater than or equal to the number of solar cells to be unloaded, the current solar cell transfer equipment can transfer all remaining solar cells to be unloaded in the current unloading batch at once. Therefore, the number of solar cells to be unloaded in the current unloading batch is used as the number of solar cells to be unloaded by the solar cell transfer equipment, thus ensuring that the solar cell loading of the solar cell transfer equipment is independently occupied by the current unloading batch, guaranteeing that the transfer of solar cells from different unloading batches is independent, further improving the accuracy of solar cell transfer, and avoiding chaotic solar cell transfer.

[0038] When the maximum cell capacity is less than the number of cells to be unloaded, the current basket carrier cannot transfer all the remaining cells in the current unloading batch. Therefore, the maximum cell capacity of the basket carrier is used as the unloading quantity. The goal is to load as many cells as possible from the current unloading batch into the current basket, ensuring the safety of cell transfer while minimizing the number of basket carriers needed for the current unloading batch, thus improving basket carrier utilization. Simultaneously, the last unloading basket in the current unloading batch only contains cells from that batch, ensuring independent cell transfer between batches and preventing confusion between different batches that could lead to errors in acquiring and recording cell process information.

[0039] In some embodiments, determining the current feeding batch and the number of cells to be fed in the current feeding batch based on work order data includes: determining the batch name and the number of cells already fed in the current feeding batch based on pre-cached historical feeding data; and determining the number of cells to be fed in the current feeding batch based on the number of cells already fed in the current feeding batch and the batch feeding quantity corresponding to the current feeding batch.

[0040] When determining the current batch and the number of cells to be fed in the current batch, the cell conveying equipment queries pre-cached historical feeding records. Based on the cell circulation quantity of the current work order in the historical feeding data, or the feeding information such as the code of the current batch, it determines the batch name and the number of cells already fed in the current batch. Then, it reads the number of cells already fed and the batch feeding quantity corresponding to the current batch in the work order data, and uses the difference between the two as the number of cells to be fed in the current batch.

[0041] By caching historical material feeding data that reflects the current work order feeding progress, and combining historical material feeding data with work order data, the current feeding batch and the number of solar cells to be fed in the current feeding batch can be accurately determined. This facilitates accurate control of the flow of solar cells in each feeding batch and avoids confusion in the flow of solar cells between different feeding batches.

[0042] Meanwhile, because historical feeding data is cached, the battery cell transmission equipment can directly control the feeding progress internally in conjunction with work order data and plan the number of battery cells to be fed into the basket carrier without interacting with the software system to determine the number of battery cells to be fed into the basket carrier. This avoids the impact of software system failures and loss of interactive information on the smooth flow of battery cells in the current basket carrier.

[0043] In some embodiments, the work order data includes the set capacity of the flower basket carrier and determining the number of battery cells to be unloaded by the flower basket carrier, including: using the set capacity as the number of battery cells to be unloaded by the flower basket carrier.

[0044] The cell transfer equipment can also forgo recording historical cell feeding data, instead relying on the software system to record feeding progress and plan the entire cell feeding process. The cell transfer equipment then directly follows the software system's feeding plan. After the cell transfer equipment reports the basket code of the basket carrier to the software system, the software system queries the maximum cell capacity of the basket carrier and checks the recorded cell feeding history to determine the current work order and its feeding progress. Then, based on the basket carrier's maximum cell capacity and the current work order's feeding progress, the software system sets a limit on the basket carrier's capacity, not exceeding the maximum cell capacity, and adds this limit to the work order data, sending it to the cell transfer equipment.

[0045] After receiving the work order data and the maximum battery cell capacity of the basket carrier, the battery cell transfer equipment can compare the set capacity with the maximum battery cell capacity of the basket carrier according to a preset algorithm. If the set capacity is not greater than the maximum battery cell capacity, the set capacity is directly used as the battery cell capacity for unloading the basket carrier. The battery cells are loaded into the basket carrier according to the set capacity for battery cell transfer. Since the battery cell transfer equipment directly transfers battery cells according to the set capacity in the work order data, there is no need to plan the unloading of the basket carrier or cache historical unloading records. This reduces the storage and computing power requirements of the battery cell transfer equipment and reduces the manufacturing difficulty and cost of the battery cell transfer equipment.

[0046] Furthermore, if the cell transfer equipment detects an anomaly in the cell flow planning when the set capacity exceeds the maximum cell capacity, it reports an error to the software system and requests the software to reissue the work order data and the maximum cell capacity. After the number of error reports exceeds a specified number, it enters a shutdown state to report the error, thus preventing cell flow chaos. By selectively reporting errors based on the detection results of the set capacity and maximum cell capacity, and automatically shutting down after multiple error reports, the possibility of cell flow chaos is further reduced.

[0047] In some embodiments, the set capacity is determined as follows: the current batch and the number of cells to be loaded in the current batch are determined based on pre-cached historical loading records; if the maximum cell capacity is greater than or equal to the number of cells to be loaded, the number of cells to be loaded is used as the set capacity; if the maximum cell capacity is less than the number of cells to be loaded, the maximum cell capacity is used as the set capacity.

[0048] After the battery cell transfer equipment uploads the basket code to the software system, the software system needs to determine the current loading batch and the number of battery cells to be loaded in the current loading batch when determining the set capacity of the basket carrier. Therefore, the software system queries the pre-cached historical loading records to obtain the loading information such as the number of battery cells already loaded, the name of the loading batch that has been completed, and the current loading batch, and then determines the current loading batch of the current work order. Combining the batch loading quantity and the number of battery cells already loaded in the current loading batch, the system determines the number of battery cells to be loaded in the current batch and compares the maximum battery cell capacity with the capacity of the battery cells to be loaded.

[0049] When the maximum cell capacity is greater than or equal to the number of cells to be unloaded, the current basket carrier can transfer all remaining cells from the current unloading batch in one go. Therefore, by using the number of cells to be unloaded in the current unloading batch as the set capacity, the current basket carrier's cell loading is independently occupied by the current unloading batch, ensuring that the flow of cells from different unloading batches is independent, further improving the accuracy of cell flow and avoiding confusion in cell flow.

[0050] When the maximum cell capacity is less than the number of cells to be unloaded, the current basket carrier cannot transfer all the remaining cells to be unloaded in the current batch. Therefore, the maximum cell capacity of the basket carrier is used as the set capacity, and the current basket is used to transfer as many cells to be unloaded in the current batch as possible. While ensuring the safety of cell transfer, the number of basket carriers needed for the current batch is reduced as much as possible, thereby improving the utilization rate of the basket carriers.

[0051] In some embodiments, reporting the basket code of the basket carrier to the software system includes: monitoring the location of each basket carrier in each transmission track; sequentially acquiring and reporting the basket code of each basket carrier according to the arrival time of each basket carrier to the unloading position; and determining the number of unloaded battery cells of the basket carrier, including: determining the number of unloaded battery cells of each basket carrier one by one according to the arrival time corresponding to each basket carrier.

[0052] The cell transfer equipment can be connected to one or more transfer tracks. When connected to multiple transfer tracks, the equipment needs to monitor the presence and current location of basket carriers on each track, and obtain the arrival time of each basket carrier at the unloading position. When reporting the basket carrier codes to the software system, the arrival times of each basket carrier at the unloading position are sorted from earliest to latest in time, and the basket codes of each basket carrier arriving at the unloading position are obtained and reported sequentially according to the sorting result.

[0053] In determining the number of battery cells to be unloaded by each flower basket carrier, the number of battery cells to be unloaded by each flower basket carrier is determined sequentially based on their arrival times. Specifically, given the flower basket codes of multiple flower basket carriers, the number of battery cells to be unloaded by the earliest arrival time among the flower basket carriers whose unloaded battery cell counts are still unknown is first determined. Then, the flower basket carrier with the earliest arrival time is selected again from the remaining flower basket carriers whose unloaded battery cell counts are still unknown, and the number of battery cells to be unloaded by that flower basket carrier is determined, until the number of battery cells to be unloaded by all flower basket carriers that have arrived at their unloading positions is determined.

[0054] By determining the number of battery cells to be unloaded for each basket carrier based on their arrival time, the system avoids situations where multiple baskets arrive at the unloading position within a short interval. This prevents the historical unloading quantity from not being updated in time during the synchronous allocation of unloaded battery cells, which could lead to the total unloaded quantity of multiple baskets exceeding the batch unloading quantity or work order unloading quantity. Consequently, the actual unloaded quantity would not match the plan, increasing production costs and affecting the overall production line efficiency.

[0055] It's important to understand that when allocating the number of solar cells to be unloaded from multiple basket carriers, there might be issues where basket carriers on two different transport tracks arrive at the same time, or the error in arrival time might be undetectable by sensors. Therefore, the unloading planning priority for each transport track can be pre-stored in the solar cell transport equipment or software system. That is, if at least two basket carriers arrive at the unloading position at the same time, the unloading quantity of the basket carrier on the higher-priority transport track is reported and planned first. If no basket carriers arrive at the same time, the unloading quantity is planned for each basket carrier one by one based on their arrival time. By setting unloading planning priorities for the transport tracks, when basket carriers on different transport tracks arrive at the same time or the error is so small that it cannot be identified, the unloading quantity of solar cells can be planned for each basket carrier in priority order, ensuring smooth solar cell flow and avoiding confusion in solar cell flow.

[0056] Furthermore, when allocating the number of solar cells to be unloaded by multiple basket carriers, a preset algorithm can be stored in advance in the solar cell conveying equipment or software system. This preset algorithm is used to break down the planned number of solar cells to be unloaded from the work order data, allocating this planned number to each conveying track. Then, after the basket carriers on the conveying tracks arrive at the unloading position, the number of solar cells to be unloaded by the basket carrier is determined based on the allocated number of cells, the historical number of cells to be unloaded, and the maximum solar cell capacity of the basket carrier. By pre-allocating the planned number of solar cells to be unloaded to each conveying track, and then independently determining the number of solar cells to be unloaded by the basket carriers on each conveying track, the discrepancy between the actual unloaded number and the expected number of solar cells is avoided due to the synchronous planning of the number of solar cells to be unloaded by basket carriers on different conveying tracks, thus improving the accuracy of solar cell flow.

[0057] In some embodiments, after determining the number of battery cells to be unloaded by the flower basket carrier, the method further includes updating historical unloading data based on the number of battery cells to be unloaded by the flower basket carrier.

[0058] With a cached history of battery cell transfer data, the battery cell transfer equipment can update its cached historical data after determining the number of batteries to be unloaded from the basket carrier. This update can be done after the basket carrier has finished loading, before loading, or during loading, based on the current number of batteries being unloaded. By updating the historical data based on the current number of batteries being unloaded from the basket carrier, consistency between the historical data and the battery cell transfer progress is ensured, improving the accuracy of transfer planning based on historical data and preventing subsequent confusion in battery cell transfer planning.

[0059] In addition, it is important to understand that when the software system stores the historical records of cell transfer, it will update its cached historical data based on the number of cells unloaded by the basket carrier after sending the work order data to the cell transfer equipment or after the cell transfer equipment has finished loading the cells. This ensures that the cached records are consistent with the actual progress and avoids confusion in the cell transfer planning.

[0060] Step 104: Load the battery cells onto the basket carrier according to the number of battery cells to be fed, and record the flow information of each battery cell.

[0061] During the process of loading solar cells into the basket carrier according to the predetermined number of cells to be fed, the solar cell conveying equipment records each solar cell transferred to the basket carrier and the order in which the solar cells flow to the basket carrier, and caches the flow information of each solar cell. By recording the flow of solar cells according to the predetermined number of cells to be fed, the equipment ensures that the final output of solar cells is consistent with the planned output, and that the recorded flow information is accurate.

[0062] In some embodiments, the battery cell includes a battery cell tag code to record the flow information of each battery cell, including: parsing the current battery cell's code using a decoder to obtain the current battery cell's tag code; determining the current battery cell's position information in the flower basket carrier based on the battery cell flow record; and associating and storing the flower basket code and position information of the flower basket carrier with the battery cell tag code.

[0063] The solar cell transport equipment can pre-set identification codes on the solar cells it transports. These codes can be generated based on the crystal ingots used in cell manufacturing and the cell's position within those ingots, or based on the cell processing technology. The transport equipment may include a decoder. During the loading of solar cells into the unloading basket according to a predetermined quantity, the decoder parses the identification codes on each cell to obtain its unique code. Then, based on the cell flow order, the transport equipment determines the position information of each cell within the basket carrier, such as its position code and coordinates, and associates and stores the cell identification codes of each cell with its position information within the basket carrier.

[0064] By identifying the cell marking codes of the solar cells and associating these codes with the cell's location information in the basket carrier, the system accurately records the flow information of each cell through the cell transfer equipment. Furthermore, it links the cell manufacturing process with the cell flow, facilitating accurate traceability of cell-level flow information.

[0065] In some embodiments, after recording the flow information of each battery cell, the method further includes: reporting the battery cell unloading data of the basket carrier to the software system. The battery cell unloading data includes the basket code of the basket carrier, the maximum battery cell capacity, the number of unloaded battery cells, the battery cell marking code of each battery cell, and the position information of each battery cell.

[0066] After storing the cell transfer information, the cell transfer equipment, using individual basket carriers as the basic unit, reports the cell unloading data of each basket carrier to the software system. This unloading data may include the basket carrier's code, maximum cell capacity, unloaded cell capacity, cell identification code of each cell within the basket carrier, and the position information of each cell within the basket carrier. Upon receiving the unloading data from the basket carriers, the software system associates this data with the cell manufacturing process data based on the cell identification codes. By reporting the unloading data to the software system, the system links and stores the unloading data with the cell manufacturing process information, enabling accurate and efficient traceability of cell-level process and transfer information. This facilitates process analysis and optimization based on the cell's process flow information to improve cell efficiency.

[0067] Taking the cell transfer equipment, specifically the cell guide machine, as an example, the detailed process of cell transfer can be found in [reference needed]. Figure 2 After the wafer tray carrier arrives at the unloading position, the wafer guide machine, through interaction with the software system, determines the number of solar cells to be unloaded from the tray carrier. The wafer guide machine then removes the solar cells from the stacking box and transfers them to the tray carrier via the solar cell transport line. During this transfer process, a decoder in the wafer guide machine's solar cell transport line identifies the solar cell markings on the cells and, based on the cell transfer order, obtains the position information of each cell within the tray carrier. The machine then associates and records each solar cell marking with its position information within the tray carrier. Once the number of solar cells loaded in the basket carrier reaches the predetermined number of cells to be unloaded, the wafer guide machine reports the unloading data, including the basket carrier's code, maximum solar cell capacity, unloaded solar cell capacity, solar cell marking codes of each solar cell in the basket carrier, and the position information of each solar cell in the basket carrier, to the software system. The software system associates and records the unloading data with the solar cell process data based on the solar cell marking codes, ensuring the accuracy of unloading and the accuracy of recording the solar cell process flow information, and facilitating traceability of process flow information at the solar cell level.

[0068] In summary, the solar cell transfer method provided in one embodiment of this application involves reporting the basket code of the basket carrier arriving at the transfer location during the solar cell unloading process. It also receives the maximum cell capacity of the basket carrier and work order data from the software system. Based on the maximum cell capacity and work order data, the number of cells to be unloaded by the basket carrier is determined, and the transfer process is initiated. This ensures accurate control over the number of cells transferred to each basket carrier, guaranteeing that the final unloaded number matches the planned number in the work order data. This improves the accuracy of cell unloading and prevents inaccurate cell counts from causing confusion in the cell transfer records. Furthermore, the transfer information for each cell is recorded during the unloading process, facilitating traceability of cell-level process transfer information and subsequent optimization of the cell manufacturing process based on the cell's process information.

[0069] Accordingly, another embodiment of this application also provides a cell transfer device, the structural schematic diagram of which can be referred to. Figure 3 The method includes: at least one processor 301; and a memory 302 communicatively connected to the at least one processor 301; wherein the memory 302 stores instructions executable by the at least one processor 301, the instructions being executed by the at least one processor 301 to enable the at least one processor 301 to perform the solar cell transmission method in the above embodiments.

[0070] The memory and processor are connected via a bus, which can include any number of interconnecting buses and bridges, connecting various circuits of one or more processors and memories.
