[0004] When discharging materials, the existing coating inspection equipment has few sorting and pairing flow channels corresponding to the battery cells set up in the discharging device, and cannot accurately distribute the battery cells to each conveying station according to the battery cell conditions at each conveying station during discharging. As a result, in actual production, the overall sorting and pairing efficiency of the coating inspection equipment cannot meet higher production capacity requirements, and the overall processing efficiency is low.

[0005] Summary of the Invention

[0006] The main purpose of this application is to provide a discharging device and a discharging control method to solve the problem that the sorting and pairing efficiency of the film detection equipment is low and cannot meet the production capacity requirements when discharging.

[0007] In the first aspect, the present application provides a discharging device, which is applied to a film detection equipment, and includes a cache conveying mechanism, a first pairing mechanism, a second pairing mechanism, a first transfer mechanism and a control device; the first pairing mechanism has multiple transfer stations: the cache conveying mechanism is used to receive at least one target battery cell transported by the film detection equipment during the detection process; the control device is used to control the first transfer mechanism to move the target battery cell that meets the first handling condition of the cache conveying mechanism to the first pairing mechanism, and is also used to move the target battery cell that meets the second handling condition to the second pairing mechanism for pairing and combination, and when the target battery cell of the second pairing mechanism meets the first handling condition after pairing and combination, the target battery cell that meets the first handling condition of the second pairing mechanism is moved to the first pairing mechanism; the control device is also used to control the first pairing mechanism to transfer the target battery cells of the multiple transfer stations to the next station when the target battery cells fill the multiple transfer stations of the first pairing mechanism.

[0008] In the technical solution of the embodiment of the present application, a first pairing mechanism with multiple transfer stations is provided to receive multiple target battery cells at the same time. When there are target battery cells that meet the first handling conditions, the first transfer mechanism is controlled to move the target battery cells that meet the first handling conditions of the cache transfer mechanism to the first pairing mechanism; when there are target battery cells that meet the second handling conditions, the first transfer mechanism is controlled to move the target battery cells that meet the second handling conditions to the second pairing mechanism for pairing and combination, and when the target battery cells of the second pairing mechanism meet the first handling conditions after pairing and combination, the target battery cells that meet the first handling conditions of the second pairing mechanism are moved to the first pairing mechanism. The pairing mechanism is used to sort and pair the target battery cells transmitted to the cache conveying mechanism according to different handling conditions, improve the sorting and pairing efficiency, and avoid the low sorting and pairing efficiency during discharge affecting the overall processing efficiency; by controlling the automatic sorting and pairing of the target battery cells, it is also possible to automatically fill multiple conveying stations of the first pairing mechanism. After the multiple conveying stations of the first pairing mechanism are full, the first pairing mechanism is controlled to automatically transfer the target battery cells of the multiple conveying stations to the next station, which can further improve the discharge pairing efficiency, meet different production capacity requirements, and avoid direct discharge without filling multiple conveying stations, affecting the actual processing efficiency.

[0009] In some embodiments, the first transfer mechanism is disposed between the buffer conveyor mechanism and the first pairing mechanism. In embodiments of the present application, the first transfer mechanism may utilize a conveyor belt to move the target battery cell. By disposing the first transfer mechanism between the buffer conveyor mechanism and the first pairing mechanism, the target battery cell on the buffer conveyor mechanism is automatically transferred to the first pairing mechanism, thereby improving pairing and transfer efficiency and reducing the actual processing space occupied.

[0010] In some embodiments, the first transplanting mechanism includes: a first guide rail, a first carrier and multiple first conveyor belts, the first guide rail extends along the first direction; the first carrier is arranged on the first guide rail and can reciprocate along the first guide rail; multiple first conveyor belts are arranged on the first carrier, and the multiple first conveyor belts are arranged side by side along the first direction, each first conveyor belt extends along the second direction, and each first conveyor belt can reciprocate along the second direction, and the second direction is the direction from the cache conveying mechanism to the first pairing mechanism; the control device is also used to control the multiple first conveyor belts to move toward the second direction to receive the target battery cells that meet the first handling conditions of the cache conveying mechanism and move them to the first pairing mechanism; the control device is also used to control the first carrier to move along the first direction toward the second pairing mechanism, and then control the multiple first conveyor belts to move away from the second direction to receive the target battery cells that meet the first handling conditions of the second pairing mechanism. The first carrier of the first transfer mechanism moves back and forth between the cache conveying mechanism, the first pairing mechanism, and the second pairing mechanism along the first guide rail, and the moving path of the first carrier is controlled by the setting of the first guide rail. With this design, in addition to moving and transferring the target battery cells that meet the first handling conditions to the first pairing mechanism through the first conveyor belt of the first transfer mechanism, the target battery cells that meet the first handling conditions of the second pairing mechanism can be moved to the first pairing mechanism after the target battery cell pairing combination on the second pairing mechanism meets the first handling conditions, so as to fill up multiple transfer stations of the first pairing mechanism. In this way, the pairing and transfer of the target battery cells can be conveniently controlled to further improve the pairing efficiency and reduce the occupancy of the actual processing space.

[0011] In some embodiments, the second pairing mechanism includes multiple reciprocating second conveyor belts, and target battery cells that meet the first handling condition are located on the multiple second conveyor belts of the first pairing mechanism. The control device is further configured to control the multiple second conveyor belts to move toward the first transfer mechanism when the target battery cells in the second pairing mechanism are paired and meet the first handling condition, thereby moving the target battery cells on the multiple second conveyor belts to the first transfer mechanism, and then controlling the first transfer mechanism to move the target battery cells to the first pairing mechanism. The multiple second conveyor belts of the second pairing mechanism are reciprocating. This design not only allows the second conveyor belts to receive and temporarily store target battery cells that meet the second handling condition, preventing the target battery cells from being stranded on the first transfer mechanism or the buffer conveyor mechanism and affecting the subsequent transfer of target battery cells, but also allows the second conveyor belts to promptly transfer the target battery cells that meet the first handling condition to the first transfer mechanism when the target battery cells on the second pairing mechanism meet the first handling condition. The first transfer mechanism moves the target battery cells to the first pairing mechanism and fills the multiple transfer stations of the first pairing mechanism. This facilitates the control of the paired transfer of the target battery cells, simplifies the sorting and pairing process, and further improves processing efficiency.

[0012] In some embodiments, the discharging device further includes a second transfer mechanism and a material output mechanism, wherein: the second transfer mechanism is used to receive multiple battery cells from the previous inspection process; the material output mechanism is used to transfer the battery cells to the target position; the control device is also used to mark the battery cells that have been tested normally as target battery cells, mark the battery cells that have been tested abnormally as abnormal battery cells, and control the second transfer mechanism to move the abnormal battery cells to the material output mechanism, and then move the target battery cells to the cache conveying mechanism. Before sorting and pairing, the battery cells that have been tested normally and the battery cells that have been tested abnormally are first screened out from the multiple battery cells transferred from the previous inspection process. After the abnormal battery cells are directly transferred through the material output mechanism, the target battery cells are received through the cache conveying mechanism to achieve accurate pairing and transmission of the target battery cells. In this way, the positioning accuracy of the battery cells on the discharging logistics line can be improved, and the discharging efficiency and quality can be improved.

[0013] In some embodiments, the second transfer mechanism includes a second guide rail, a second carrier and multiple third conveyor belts, the second guide rail extends along the first direction; the second carrier is arranged on the second guide rail and can reciprocate along the second guide rail; multiple third conveyor belts are arranged on the second carrier, and the multiple third conveyor belts are arranged side by side along the first direction, each of the third conveyor belts extends along the second direction, and each of the third conveyor belts can reciprocate along the second direction, and the second direction is the direction from the previous inspection process to the material output mechanism; the control device is also used to control the multiple third conveyor belts to move toward the second direction to receive the abnormal battery cells from the previous inspection process and move them to the material output mechanism; the control device is also used to control the second carrier to move along the first direction toward the cache conveying mechanism, and control the multiple third conveyor belts to move toward the second direction to receive the target battery cells from the previous inspection process and move them to the cache conveying mechanism. The second carrier of the second transfer mechanism moves back and forth between the previous detection process, the material output mechanism, and the cache conveying mechanism along the second guide rail, and the moving path of the second carrier is controlled by the setting of the second guide rail. With this design, in addition to transferring the abnormal battery cells to the material output mechanism through the second conveyor belt of the second transfer mechanism, and directly transmitting the abnormal battery cells to the target position through the material output mechanism, the target battery cells can also be transferred to the cache conveying mechanism through the second conveyor belt of the second transfer mechanism after completing the transfer of the abnormal battery cells, so as to further complete the sorting, pairing and discharging of the target battery cells. In this way, the sorting and pairing process can be simplified, the transmission of the target battery cells and the abnormal battery cells can be controlled conveniently, and the pairing efficiency can be further improved.

[0014] In some embodiments, a third transfer mechanism is provided between the detection device of the coating detection equipment and the second transfer mechanism, and the third transfer mechanism includes a third guide rail, a third carrier and multiple fourth conveyor belts, and the third guide rail extends along the first direction; the third carrier is provided on the third guide rail and can reciprocate along the third guide rail; multiple fourth conveyor belts are provided on the third carrier, and the multiple fourth conveyor belts are arranged side by side along the first direction, and each of the fourth conveyor belts extends along the second direction, and the second direction is the direction from the detection device to the material output mechanism; the control device is also used to control the multiple fourth conveyor belts to move toward the second direction to receive the battery cells transferred by the detection device and move to the second transfer mechanism; the control device is also used to control the third carrier to move toward the second transfer mechanism along the first direction when the battery cells are filled on the multiple fourth conveyor belts of the third carrier, and then control the multiple third conveyor belts to move toward the second direction to receive the battery cells. The third carrier of the third transfer mechanism reciprocates along the third guide rail, and the moving path of the third carrier is controlled by the setting of the third guide rail. With this design, in addition to transferring the battery cells to the second transfer mechanism through the fourth conveyor belt of the third transfer mechanism, and directly transferring the abnormal battery cells to the target position through the second transfer mechanism and transferring the target battery cells to the cache transfer mechanism, it is also possible to continue to receive the battery cells transferred by the previous inspection process after completing the transfer of the battery cells. In this way, the transfer and pairing efficiency of the battery cells can be improved.

[0015] In some embodiments, the membrane inspection equipment includes a first inspection device and a second inspection device arranged side by side along a first direction, and the third carrier is arranged on the third guide rail and can reciprocate along the third guide rail between the first inspection device and the second inspection device to transfer the multiple battery cells transported in the previous inspection process to the second transfer mechanism. The fourth carrier of the third transfer mechanism moves back and forth along the fourth guide rail between the first inspection device and the second inspection device to receive the battery cells transferred by the first inspection device and the second inspection device, and after the battery cells fill the transfer position of the third transfer mechanism, the third transfer mechanism transfers the battery cells to the second transfer mechanism, thereby further improving the transfer and pairing efficiency of the battery cells.

[0016] In some embodiments, the discharge device further includes a code scanning device, which is disposed between the previous inspection process and the second transfer mechanism and is used to detect whether the multiple battery cells transferred from the previous inspection process are normal. The code scanning device scans the target battery cells and abnormal battery cells among the multiple battery cells transferred from the previous inspection process, thereby controlling the paired discharge of the target battery cells and abnormal battery cells based on their positions, thereby improving discharge accuracy and quality.

[0017] In some embodiments, the cache conveying mechanism and the first pairing mechanism have four conveying stations, and the first transfer mechanism has two conveying stations; the control device is used to control the first transfer mechanism to move the four target battery cells located at adjacent conveying stations on the cache conveying mechanism to the first pairing mechanism, and when the target battery cells fill the four conveying stations of the first pairing mechanism, control the first pairing mechanism to transfer the target battery cells of multiple conveying stations to the next station; the control device is also used to control the first transfer mechanism to move the two target battery cells of the cache conveying mechanism located at adjacent conveying stations to the first pairing mechanism, and also to move the other target battery cells of the cache conveying mechanism to the second pairing mechanism for pairing and combination, and when there are at least two target battery cells located at adjacent conveying stations after the target battery cells of the second pairing mechanism are paired and combined, move the two target battery cells of the second pairing mechanism located at adjacent conveying stations to the first pairing mechanism, and when the target battery cells fill the four conveying stations of the first pairing mechanism, control the first pairing mechanism to transfer the target battery cells of multiple conveying stations to the next station. By adopting a cache conveying mechanism with four conveying stations, a first pairing mechanism with four conveying stations, and a first transplanting mechanism with two conveying stations, the target battery cell pairing process is simplified, the difficulty of sorting and pairing is reduced, and the discharge efficiency is improved.

[0018] In some embodiments, the transfer stations of the buffer conveyor mechanism, the first pairing mechanism, the second pairing mechanism, and the first transfer mechanism are each equipped with a detection component, and the control device is electrically connected to the detection component to detect and determine the moving position of the target battery cell via the detection component. The detection component detects whether the target battery cell is located at each transfer station of the buffer conveyor mechanism, the first pairing mechanism, the second pairing mechanism, and the first transfer mechanism to determine the moving position of the target battery cell, and further regulates the sorting and pairing process based on the moving position of each target battery cell, thereby improving processing efficiency.

[0019] In the second aspect, the present application provides a discharging control method, which is applied to a discharging device, wherein the discharging device includes a cache conveying mechanism, a first pairing mechanism, a second pairing mechanism and a first transferring mechanism, wherein the first pairing mechanism has multiple transferring stations, and the cache conveying mechanism is used to receive at least one target battery cell; the discharging control method includes the following steps: controlling the first transferring mechanism to move the target battery cell that meets the first handling condition of the cache conveying mechanism to the first pairing mechanism, and moving the target battery cell that meets the second handling condition to the second pairing mechanism for pairing and combination; when the target battery cell of the second pairing mechanism meets the first handling condition after pairing and combination, moving the target battery cell that meets the first handling condition of the second pairing mechanism to the first pairing mechanism; when the target battery cells fill the multiple transfer stations of the first pairing mechanism, controlling the first pairing mechanism to transfer the target battery cells of the multiple transfer stations to the next station.

Before executing the step of controlling the first transfer mechanism to move the target battery cells that meet the first handling condition of the buffer conveying mechanism to the first pairing mechanism and to move the target battery cells that meet the second handling condition to the second pairing mechanism for pairing and combination, the discharge control method further includes: calibrating the battery cells that have been tested normally as target batteries and calibrating the battery cells that have been tested abnormally as abnormal batteries; controlling the second transfer mechanism to move the abnormal battery cells to the material output mechanism, and then moving the target battery cells to the buffer conveying mechanism.

[0037] Most existing coated cell inspection equipment requires conveyor lines to transport and discharge cells. However, during discharge, the discharge device has few sorting and pairing channels corresponding to the cells, and the cells cannot be accurately allocated to each transfer station according to their conditions. As a result, the overall sorting and pairing efficiency of the coated cell inspection equipment cannot meet the higher production capacity requirements in actual production, resulting in low overall processing efficiency. Therefore, how to improve the sorting and pairing efficiency of coated cell inspection equipment during discharge has become a technical problem that needs to be solved urgently.

[0038] In order to solve the above technical problems, the present application provides a discharging device and a discharging control method, which are used to sort and pair the target battery cells transmitted to the cache conveying mechanism 200 according to different handling conditions, improve the sorting and pairing efficiency by controlling the automatic sorting and pairing of the target battery cells, and control the automatic discharging after the target battery cells automatically fill multiple conveying stations of the first pairing mechanism 300, so as to avoid the low sorting and pairing efficiency during discharging affecting the overall processing efficiency.

[0039] According to some embodiments of the present application, with reference to Figures 1 to 3, and further with reference to Figures 4 to 8, Figure 1 is a layout diagram of a discharge device in some embodiments of the present application, and Figures 2 and 3 are schematic diagrams of the functional modules of the discharge device in some embodiments of the present application; Figures 4 to 8 are flow charts of a discharge control method in some embodiments of the present application. The present application provides a discharge device, which is applied to a film detection device and includes a buffer conveying mechanism 200, a first pairing mechanism 300, a second pairing mechanism 400, a first transplanting mechanism 500, and a control device 10. Among them:

[0040] The first pairing mechanism 300 has a plurality of conveying stations: the buffer conveying mechanism 200 is used to receive at least one target battery cell conveyed by the coating detection device during the detection process.

[0041] The control device 10 is used to control the first transplanting mechanism 500 to move the target battery cell that meets the first handling condition of the cache conveying mechanism 200 to the first pairing mechanism 300, and is also used to move the target battery cell that meets the second handling condition to the second pairing mechanism 400 for pairing and combination, and when the target battery cell of the second pairing mechanism 400 meets the first handling condition after pairing and combination, the target battery cell that meets the first handling condition of the second pairing mechanism 400 is moved to the first pairing mechanism 300.

[0042] The control device 10 is further configured to control the first pairing mechanism 300 to transfer the target battery cells at the plurality of transfer stations to the next station when the plurality of transfer stations of the first pairing mechanism 300 are fully filled with the target battery cells.

[0043] The coating inspection equipment is used to complete at least one inspection process. The previous inspection process transmits at least one battery cell to the discharge device. The cache conveying mechanism 200 of the discharge device is used to receive the target battery cell among the battery cells transmitted by the previous inspection process. The target battery cell can be, but is not limited to, a battery cell that was detected normally in the previous inspection process, a battery cell that was detected abnormally in the previous inspection process, a battery cell that needs to be conveyed to the next workstation or other target position through the shown discharge device, etc.

[0044] To improve sorting and pairing efficiency, whether the target battery cell meets the first and second handling conditions can be determined based on the target battery cell's transfer position and quantity. The buffer conveyor mechanism 200 is used to receive at least one target battery cell. Specifically, the buffer conveyor mechanism 200 can be provided with multiple transfer stations, each receiving one target battery cell, and the multiple transfer stations can be arranged in parallel. Alternatively, the buffer conveyor mechanism 200 can be provided with one or more conveyor belts or other conveying channels, and the received multiple target batteries can be conveyed in parallel.

[0045] In the present application, the first pairing mechanism 300 has multiple transfer stations. Optionally, the cache transfer mechanism 200 and the first transfer mechanism 500 may have multiple transfer stations, with one transfer station corresponding to the transfer of one target battery cell. Specifically, two or more target battery cells located at adjacent transfer stations of the cache transfer mechanism 200 are determined as target battery cells that meet the first handling condition; one target battery cell individually transferred by the cache transfer mechanism 200, two or more target battery cells located at spaced transfer stations, and other target battery cells remaining except those that meet the first handling condition are determined as target battery cells that meet the second handling condition.

[0046] The buffer conveyor mechanism 200 is used to receive at least one target battery cell. The target battery cells received by the buffer conveyor mechanism 200 may include, but are not limited to, target battery cells that meet the first handling condition, target battery cells that meet the second handling condition, and other target battery cells. Optionally, in an embodiment where the buffer conveyor mechanism 200 receives only one target battery cell, the target battery cell may be determined to be a target battery cell that meets the second handling condition. In an embodiment where the buffer conveyor mechanism 200 conveys multiple target battery cells, two or more target battery cells located at adjacent conveying stations may be determined to be target battery cells that meet the first handling condition. The target battery cells that meet the second handling condition may be the target battery cells among the multiple target battery cells conveyed, excluding those that meet the first handling condition.

[0047] In the technical solution of the embodiment of the present application, a first pairing mechanism 300 with multiple conveying stations is provided to simultaneously receive multiple target battery cells. When there are target battery cells that meet the first conveying conditions, the first transferring mechanism 500 is controlled to move the target battery cells that meet the first conveying conditions of the cache conveying mechanism 200 to the first pairing mechanism 300. When there are target battery cells that meet the second conveying conditions, the first transferring mechanism 500 is controlled to move the target battery cells that meet the second conveying conditions to the second pairing mechanism 400 for pairing and combination. When the target battery cells of the second pairing mechanism 400 meet the first conveying conditions after pairing and combination, the target battery cells that meet the first conveying conditions of the second pairing mechanism 400 are moved to the first pairing mechanism 300, so as to sort, pair and combine the target battery cells conveyed to the cache conveying mechanism 200 according to different conveying conditions, improve the sorting and pairing efficiency, and avoid the low sorting and pairing efficiency during discharge affecting the overall processing efficiency. By controlling the automatic sorting and pairing of target battery cells, it is also possible to automatically fill multiple transfer stations of the first pairing mechanism 300. After the multiple transfer stations of the first pairing mechanism 300 are full, the first pairing mechanism 300 is controlled to automatically transfer the target battery cells of the multiple transfer stations to the next station, which can further improve the discharge pairing efficiency, meet different production capacity requirements, and avoid direct discharge when multiple transfer stations are not full, affecting the actual processing efficiency.

[0048] In this embodiment of the present application, the target battery cell of the buffer conveyor mechanism 200 is moved to the first pairing mechanism 300 via a first transfer mechanism 500. The first transfer mechanism 500 may be, but is not limited to, a conveyor belt, a transmission roller, a mechanical gripper, etc. For ease of description, the following embodiment is described using an embodiment of the present application in which the first transfer mechanism 500 includes a conveyor belt as an example.

[0049] Please refer to Figure 1, which shows the layout of the discharge device in some embodiments of the present application. The first transfer mechanism 500 is located between the buffer conveyor mechanism 200 and the first pairing mechanism 300. In embodiments of the present application, the first transfer mechanism 500 can utilize a conveyor belt to move the battery cells. By placing the first transfer mechanism 500 between the buffer conveyor mechanism 200 and the first pairing mechanism 300, the target battery cell from the buffer conveyor mechanism 200 is automatically transferred to the first pairing mechanism 300, thereby improving pairing and transfer efficiency and reducing the actual processing space occupied.

[0050] Referring to Figure 1 , the Y direction in Figure 1 is the first direction, and the X direction is the second direction. In some embodiments, the first transfer mechanism 500 includes a first guide rail 501, a first carrier 502, and a plurality of first conveyor belts 503. The first guide rail 501 extends along a first direction; the first carrier 502 is mounted on the first guide rail 501 and is reciprocatable along the first guide rail 501; and the plurality of first conveyor belts 503 are mounted on the first carrier 502. The plurality of first conveyor belts 503 are arranged side by side along the first direction, each of the first conveyor belts 503 extends along a second direction, and each of the first conveyor belts 503 is reciprocatable along the second direction. The second direction is the direction from the buffer conveyor mechanism 200 to the first pairing mechanism 300.

[0051] The control device 10 is also used to control multiple first conveyor belts 503 to move in the second direction to receive the target battery cells that meet the first handling conditions from the cache conveying mechanism 200 and move them to the first matching mechanism 300; the control device 10 is also used to control the first carrier 502 to move along the first direction toward the second matching mechanism 400, and then control the multiple first conveyor belts 503 to move away from the second direction to receive the target battery cells that meet the first handling conditions from the second matching mechanism 400.

[0052] When receiving target cells from the buffer conveyor mechanism 200, the first carrier 502 is controlled to move along the first guide rail 501, driving the multiple first conveyor belts 503 to move in a first direction toward the buffer conveyor mechanism 200. The multiple first conveyor belts 503 then move in a second direction to receive target cells from the buffer conveyor mechanism 200 that meet the first handling conditions and then move and transfer the target cells to the first pairing mechanism 300. When the target cells from the second pairing mechanism 400 meet the first handling conditions after pairing, the first carrier 502 is controlled to move along the first guide rail 501, driving the multiple first conveyor belts 503 to move in the first direction toward the second pairing mechanism 400. The multiple first conveyor belts 503 then move away from the second direction to receive target cells from the second pairing mechanism 400 that meet the first handling conditions. This facilitates the control of the pairing and transfer of target cells, further improving pairing efficiency and reducing the actual processing space occupied.

[0053] In this application, each conveyor belt has a conveying station as shown. The first pairing mechanism 300 has multiple conveying stations. Optionally, the buffer conveying mechanism 200 and the first transfer mechanism 500 can have multiple conveying stations, with one conveying station corresponding to conveying one target battery cell. The number of conveying stations of the first transfer mechanism 500 is not greater than the number of conveying stations of the buffer conveying mechanism 200 and the first pairing mechanism 300. The first carrier 502 of the first transplanting mechanism 500 moves back and forth between the cache conveying mechanism 200, the first pairing mechanism 300, and the second pairing mechanism 400 along the first guide rail 501. The moving path of the first carrier 502 is controlled by the setting of the first guide rail 501. During the movement of the first carrier 502 along the first guide rail 501, it drives multiple first conveyor belts 503 to move and adjusts the cascade positions of the multiple first conveyor belts 503 and the cache conveying mechanism 200, the first pairing mechanism 300, and the second pairing mechanism 400 to transfer the target battery cells that meet the first handling conditions to the first pairing mechanism 300 and fill the multiple transfer stations of the first pairing mechanism 300.

[0054] The number of transfer stations of the first transfer mechanism 500 is smaller than the number of transfer stations of the cache transfer mechanism 200 and the first pairing mechanism 300. Optionally, the number of target battery cells located at adjacent transfer stations that need to be included when the first handling condition is met can be determined based on the number of transfer stations included in the first transfer mechanism 500 to improve the sorting and pairing accuracy.

[0055] In some embodiments, the second pairing mechanism 400 has a plurality of reciprocating second conveyor belts 401 , and the target battery cells meeting the first transport condition are located on the plurality of second conveyor belts 401 of the second pairing mechanism 400 .

[0056] The control device 10 is also used to control the multiple second conveyor belts 401 to move toward the first transfer mechanism 500 when the target battery cells of the second pairing mechanism 400 are paired and combined to meet the first transportation condition, so as to move the target battery cells of the multiple second conveyor belts 401 to the first transfer mechanism 500, and then control the first transfer mechanism 500 to move the target battery cells to the first pairing mechanism 300.

[0057] The multiple second conveyor belts 401 of the second pairing mechanism 400 can move back and forth. This design, in addition to receiving and temporarily storing target battery cells that meet the second handling conditions through the second conveyor belt 401, thereby preventing the target battery cells from being stranded in the first transfer mechanism 500 or the cache transfer mechanism 200 and affecting the subsequent transfer of target battery cells, is also used to promptly transfer the target battery cells that meet the first transfer conditions to the first transfer mechanism 500 through the second conveyor belt 401 after the target battery cells of the second pairing mechanism 400 meet the first transfer conditions, so as to move the target battery cells to the first pairing mechanism 300 through the first transfer mechanism 500 and fill up multiple transfer stations of the first pairing mechanism 300. In this way, the pairing and transfer of the target battery cells can be conveniently controlled, the sorting and pairing process can be simplified, and the processing efficiency can be further improved.

[0058] Taking the normal battery cells detected in the previous inspection process as the target battery cells as an example, in some embodiments, the discharge device also includes a second transfer mechanism 600 and a material output mechanism 730, wherein: the second transfer mechanism 600 is used to receive multiple battery cells from the previous inspection process; the material output mechanism 730 is used to transfer the battery cells to the target position.

[0059] The control device 10 is also used to mark the battery cells that have been tested normally as target battery cells, mark the battery cells that have been tested abnormally as abnormal battery cells, and control the second transfer mechanism 600 to move the abnormal battery cells to the material output mechanism 730, and then move the target battery cells to the buffer conveying mechanism 200. Before sorting and pairing, the normal battery cells and the abnormal battery cells from the multiple battery cells transmitted in the previous inspection process are first screened out. After the abnormal battery cells are directly transferred through the material output mechanism 730, the target battery cells are received by the buffer conveying mechanism 200 to achieve precise pairing and transmission of the target battery cells. In this way, the positioning accuracy of the battery cells in the discharge logistics line can be improved, and the discharge efficiency and discharge quality can be improved.

[0060] In some embodiments, the second transplanting mechanism 600 includes a second guide rail 601, a second carrier 602 and multiple third conveyor belts 603, the second guide rail 601 extends along the first direction; the second carrier 602 is arranged on the second guide rail 601 and can reciprocate along the second guide rail 601; multiple third conveyor belts 603 are arranged on the second carrier 602, and the multiple third conveyor belts 603 are arranged side by side along the first direction, each third conveyor belt 603 extends along the second direction, and each third conveyor belt 603 can reciprocate along the second direction, and the second direction is the direction from the previous inspection process to the material output mechanism 730.

[0061] The control device 10 is also used to control multiple third conveyor belts 603 to move in the second direction to receive abnormal battery cells from the previous inspection process and move them to the material output mechanism 730; the control device 10 is also used to control the second carrier 602 to move along the first direction toward the cache conveying mechanism 200, and control multiple third conveyor belts 603 to move in the second direction to receive target battery cells from the previous inspection process and move them to the cache conveying mechanism 200.

[0062] When receiving an abnormal cell from the previous inspection process, the second carrier 602 is controlled to move along the second guide rail 601, driving the multiple second conveyor belts 401 to move in the second direction toward the previous inspection process. The multiple second conveyor belts 401 move in the second direction to receive an abnormal cell from the multiple cells from the previous inspection process and move the abnormal cell to the material output mechanism 730. After receiving the target cell from the previous inspection process, the second carrier 602 is controlled to move along the second guide rail 601 toward the buffer conveyor mechanism 200 to move the target cell to the buffer conveyor mechanism 200. In this way, the transmission of the target cell and the abnormal cell can be conveniently controlled, further improving pairing efficiency.

[0063] The second carrier 602 of the second transplanting mechanism 600 moves back and forth along the second guide rail 601 between the previous detection process, the material output mechanism 730, and the cache conveying mechanism 200. The movement path of the second carrier 602 is controlled by the setting of the second guide rail 601. During the movement of the second carrier 602 along the second guide rail 601, it drives multiple second conveyor belts 401 to move, and adjusts the cascade position of multiple second conveyor belts 401 and the previous detection process, the material output mechanism 730, and the cache conveying mechanism 200, so as to move the abnormal battery cell to the material output mechanism 730, and then move the target battery cell to the cache conveying mechanism 200, so as to further simplify the sorting and pairing process, facilitate the control of the transmission of the target battery cell and the abnormal battery cell, and improve the discharge efficiency.

[0064] In this embodiment of the present application, the first transfer mechanism 500 is used to move the target battery cells that meet the first handling conditions of the buffer conveyor mechanism 200 to the first pairing mechanism 300, and is also used to move the target battery cells that meet the second handling conditions to the second pairing mechanism 400 for pairing and combination. In this application, the first pairing mechanism 300 has multiple transfer stations. Optionally, the buffer conveyor mechanism 200 and the first transfer mechanism 500 can have multiple transfer stations, with each transfer station corresponding to the transfer of one target battery cell. Typically, the coated battery cell inspection equipment will be equipped with multiple test devices for each inspection process to implement the corresponding inspection process. Each test device is used to inspect one or more battery cells on the conveyor line and complete the delivery and discharge of the battery cells through the conveyor line after the inspection is completed. Specifically, the number of transfer stations of the buffer conveyor mechanism 200 can be, but is not limited to, M, and the number of transfer stations of the first transfer mechanism 500 can be, but is not limited to, N. M and N are positive integers not less than 2, and M ≥ N. Wherein, M can be, but is not limited to, 2N or other integer multiples of N. For example, when the number of transfer stations of the cache transfer mechanism 200 is four, the number of transfer stations of the first transfer mechanism 500 can be two; when the number of transfer stations of the cache transfer mechanism 200 is six, the number of transfer stations of the first transfer mechanism 500 can be two, three or four.

[0065] The first pairing mechanism 300 is used to transfer the target battery cells of multiple transfer stations to the next station after the target battery cells fill their transfer stations. The first pairing mechanism 300 can have two or more transfer stations. The second pairing mechanism 400 is used to place the target battery cells that meet the second handling conditions, and when the target battery cells meet the first handling conditions after being paired and combined, the target battery cells that meet the first handling conditions are moved to the first pairing mechanism 300 through the first transfer mechanism 500. The second pairing mechanism 400 can have two or more transfer stations.

[0066] According to some embodiments of the present application, optionally, the number of transfer stations of the first pairing mechanism 300 may correspond to the number of transfer stations of the cache transfer mechanism 200, and the number of transfer stations of the second pairing mechanism 400 may not be greater than the number of transfer stations of the first pairing mechanism 300, so as to reduce the pairing process and improve the discharge efficiency.

[0067] If target cells are placed at the transfer stations of the first pairing mechanism 300, but the target cells do not fill up the transfer stations of the first pairing mechanism 300, as long as the target cells of the second pairing mechanism 400 can fill up the transfer stations of the first pairing mechanism 300, that is, the number of target cells in the second pairing mechanism 400 is not less than the number of idle transfer stations of the first pairing mechanism 300, it can be determined that the second pairing mechanism 400 has target cells that meet the first handling condition. "Idle transfer stations" refer to transfer stations where no cells are placed.

[0068] According to some embodiments of the present application, the cache conveying mechanism 200 and the first pairing mechanism 300 have four conveying stations, and the first transfer mechanism 500 has two conveying stations.

[0069] The control device 10 is used to control the first transfer mechanism 500 to move the four target battery cells located at adjacent transfer stations of the cache transfer mechanism 200 to the first pairing mechanism 300. When the target battery cells fill the four transfer stations of the first pairing mechanism 300, the first pairing mechanism 300 is controlled to transfer the target battery cells of multiple transfer stations to the next station.

[0070] The control device 10 is also used to control the first transplanting mechanism 500 to move the two target battery cells located at adjacent transfer stations of the cache conveying mechanism 200 to the first pairing mechanism 300, and is also used to move the other target battery cells of the cache conveying mechanism 200 to the second pairing mechanism 400 for pairing and combination, and when there are at least two target battery cells located at adjacent transfer stations after the target battery cells of the second pairing mechanism 400 are paired and combined, the two target battery cells located at adjacent transfer stations of the second pairing mechanism 400 are moved to the first pairing mechanism 300, and when the target battery cells fill the four transfer stations of the first pairing mechanism 300, the first pairing mechanism 300 is controlled to transfer the target battery cells of multiple transfer stations to the next station.

[0071] The pairing process is simplified by employing a buffer transfer mechanism 200 having four transfer stations, a first pairing mechanism 300 having four transfer stations, and a first transfer mechanism 500 having two transfer stations. In this application, the second pairing mechanism 400 is provided with two transfer stations, which further simplifies the pairing process, avoids the excessive number of transfer stations provided by the second pairing mechanism 400 affecting the sorting and pairing efficiency of the target cells, further reduces the difficulty of sorting and pairing, and improves discharge efficiency.

[0072] In some embodiments, the transfer stations of the cache conveying mechanism 200, the first pairing mechanism 300, the second pairing mechanism 400, and the first transplanting mechanism 500 are all provided with a detection component 12, and the control device 10 is electrically connected to the detection component 12 to detect and determine the moving position of the target battery cell through the detection component 12. The present application detects whether there is a target battery cell at each transfer station of the cache conveying mechanism 200, the first pairing mechanism 300, the second pairing mechanism 400, and the first transplanting mechanism 500 through the detection component 12. The detection component 12 can be, but is not limited to, a photoelectric detector, etc. Specifically, the detection component 12 can be respectively provided corresponding to the cache conveying mechanism 200, the first pairing mechanism 300, the second pairing mechanism 400, and the first transplanting mechanism 500, so as to further regulate the sorting and pairing process according to the moving position of each target battery cell.

[0073] In some embodiments, the discharge device further includes a code scanning device 11, which is disposed between the previous inspection process and the second transfer mechanism 600 and is used to detect whether the multiple battery cells transferred from the previous inspection process are normal. In the present application, the code scanning device 11 is used to scan the target battery cells and abnormal battery cells among the multiple battery cells transferred from the previous inspection process, so as to control the paired discharge of the target battery cells and the abnormal battery cells according to their positions, thereby improving the discharge accuracy and quality.

[0074] In some embodiments, the second transplanting mechanism 600 is used to receive multiple battery cells delivered by the previous inspection process. In the present application, in order to improve the yield rate, the previous inspection process may be, but not limited to, an insulation test. Taking the previous inspection process as an insulation test as an example, the inspection device 810 of the coating inspection equipment may be, but not limited to, an insulation testing device, and the second transplanting mechanism 600 is used to receive multiple battery cells delivered by the inspection device 810, such as the insulation testing device. The abnormal battery cells determined after the inspection are transported to the material output mechanism 730 by the second transplanting mechanism 600, and the target battery cells determined after the inspection are transported to the cache transport mechanism 200, so as to improve the yield rate and transport efficiency of the battery cells.

[0075] In some embodiments, a third transplanting mechanism 820 is provided between the detection device 810 of the coating detection equipment and the second transplanting mechanism 600. The third transplanting mechanism 820 includes a third guide rail 821, a third carrier 822 and multiple fourth conveyor belts 823. The third guide rail 821 extends along the first direction; the third carrier 822 is provided on the third guide rail 821 and can reciprocate along the third guide rail 821; multiple fourth conveyor belts 823 are provided on the third carrier 822, and the multiple fourth conveyor belts 823 are arranged side by side along the first direction. Each fourth conveyor belt 823 extends along the second direction. The second direction is the direction from the detection device 810 to the material output mechanism 730. The control device 10 is further configured to control the plurality of fourth conveyor belts 823 to move in the second direction to receive the battery cells conveyed by the detection device 810 and move them to the second transfer mechanism 600. When the plurality of fourth conveyor belts 823, which are loaded with battery cells, are filled with the third carrier 822, the control device 10 is further configured to control the third carrier 822 to move in the first direction toward the second transfer mechanism 600, and then control the plurality of third conveyor belts 603 to move in the second direction to receive the battery cells. To reduce space usage, the detection device 810 and the material output mechanism 730 are positioned opposite each other, with the third transfer mechanism 820 and the second transfer mechanism 600 positioned between the detection device 810 and the material output mechanism 730.

[0076] The detection device 810 includes a first detection device 811 and a second detection device 812 arranged side by side along a first direction. The third carrier 822 is disposed on the third guide rail 821 and is reciprocatable along the third guide rail 821 between the first detection device 811 and the second detection device 812 to transfer the multiple battery cells of the detection device 810 to the second transfer mechanism 600. In some embodiments of the present application, the code scanning device 11 is disposed between the previous detection process and the second transfer mechanism 600. Specifically, the code scanning device 11 is disposed between the detection device 810 and the third transfer mechanism 820 to determine whether the multiple battery cells transferred after the previous detection process are normal. In the present application, the second transporting mechanism 600 and the third transporting mechanism 820 have four or more transfer positions. The first detection device 811 can perform insulation testing and other detection processes on two or more battery cells at the same time, and the second detection device 812 is also the same. The third transporting mechanism 820 moves along the third guide rail 821 between the first detection device 811 and the second detection device 812 to receive four or more battery cells transferred by the first detection device 811 and the second detection device 812, and is used to transfer the four or more battery cells to the second transporting mechanism 600 after the transfer position of the third transporting mechanism 820 is full, and the abnormal battery cells among the four or more battery cells are moved to the material output mechanism 730 through the second transporting mechanism 600, and the target battery cells among the four or more battery cells are moved to the cache transport mechanism 200.

[0077] Optionally, the plurality of fourth conveyor belts 823 of the third transfer mechanism 820 may be relatively movably disposed on the third carrier 822 to simultaneously receive the battery cells transferred by the first detection device 811 and the second detection device 812; or, the plurality of fourth conveyor belts 823 of the third transfer mechanism 820 may be relatively fixedly disposed on the third carrier 822 to sequentially receive the battery cells transferred by the first detection device 811 and the second detection device 812. By disposing the third transfer mechanism 820 between the detection device 810 and the second transfer mechanism 600, the third transfer mechanism 820 simultaneously transfers the battery cells in its transfer position to the second transfer mechanism 600 when the transfer position is full, thereby avoiding the inability to simultaneously screen out target battery cells and abnormal battery cells from the multiple battery cells, which would affect the battery cell distribution process.

[0078] According to some embodiments of the present application, the discharge device further includes a discharge and transfer mechanism 710 and a discharge mechanism 720. The discharge and transfer mechanism 710 includes a fourth guide rail 711, a fourth carrier 712, and a plurality of fifth conveyor belts 713. The fourth guide rail 711 extends along a first direction (the Y direction in FIG. 1 ); the fourth carrier 712 is disposed on the fourth guide rail 711 and is reciprocatable along the fourth guide rail 711; and a plurality of fifth conveyor belts 713 are disposed on the fourth carrier 712. The plurality of fifth conveyor belts 713 are arranged side by side along the first direction, each fifth conveyor belt 713 extends along a second direction, and each fifth conveyor belt 713 is reciprocatable along the second direction. The second direction is the direction from the first pairing mechanism 300 to the discharge mechanism 720 (the X direction in FIG. 1 ). The control device 10 is further configured to control the plurality of fifth conveyor belts 713 to move in the second direction to receive four or more target battery cells transmitted by the first pairing mechanism 300 and move them to the discharge mechanism 720. In this way, the paired target cells can be conveniently transferred, so that four or more paired target cells can be simultaneously transferred to the next workstation through the discharge mechanism 720 to further improve the processing efficiency.

[0079] Referring to FIG1 , and further to FIG2 and FIG3 , in some embodiments, a belt-pulling motor 15 is provided for each conveyor belt of each conveyor mechanism, such as the first buffer conveyor mechanism 200 , the first pairing mechanism 300 , the second pairing mechanism 400 , the first transfer mechanism 500 , the second transfer mechanism 600 , the discharge transfer mechanism 710 , the material output mechanism 730 , and the third transfer mechanism 820 . A control device 10 is used to control the operation of the belt-pulling motor 15 of each conveyor mechanism to control the movement of the conveyor belt of each conveyor mechanism. Furthermore, a switch assembly 13 , such as a relay or a drive cylinder, may be provided for each conveyor mechanism to activate or deactivate the conveyor belt of each conveyor mechanism. Specifically, in terms of the actual discharge and processing process, a speed regulating device 14 , such as an electronic speed regulator, may be provided for each conveyor mechanism to adjust the conveying speed of the conveyor belt of each conveyor mechanism. Multiple conveyor belts provided on the same conveyor mechanism can be driven independently or simultaneously. When the conveyor belts provided on the same conveyor mechanism are independent of each other, the conveying speeds of the conveyor belts can be the same or different. According to the actual discharge and processing progress, a request can also be sent when conveying the battery cells, and the guide rails of the conveying mechanisms such as the first transfer mechanism 500, the second transfer mechanism 600, the discharge transfer mechanism 710, and the third transfer mechanism 820 can be controlled by driving devices such as the motor servo driver 16 to drive the corresponding conveyor belt movement.

[0080] According to some embodiments of the present application, referring to Figures 4 to 8, the present application also provides a discharging control method, which is applied to a discharging device. The discharging device includes a cache conveying mechanism 200, a first pairing mechanism 300, a second pairing mechanism 400 and a first transplanting mechanism 500. The first pairing mechanism 300 has multiple conveying stations, and the cache conveying mechanism 200 is used to receive at least one target battery cell.

[0081] The discharge control method comprises the following steps:

[0082] Step S100: Control the first transfer mechanism 500 to move the target battery cells meeting the first transport condition of the buffer conveying mechanism 200 to the first pairing mechanism 300, and move the target battery cells meeting the second transport condition to the second pairing mechanism 400 for pairing and combination;

[0083] Step S200 , when the target battery cells of the second pairing mechanism 400 meet the first transport condition after being paired and combined, the target battery cells meeting the first transport condition of the second pairing mechanism 400 are moved to the first pairing mechanism 300 ;

[0084] Step S300 : When the target battery cells fill up the multiple transfer stations of the first pairing mechanism 300 , control the first pairing mechanism 300 to transfer the target battery cells in the multiple transfer stations to the next station.

[0085] In the technical solution of the embodiment of the present application, when there is a target battery cell that meets the first transport condition, the first transfer mechanism 500 is controlled to move the target battery cell that meets the first transport condition of the cache conveying mechanism 200 to the first pairing mechanism 300; when there is a target battery cell that meets the second transport condition, the first transfer mechanism 500 is controlled to move the target battery cell that meets the second transport condition to the second pairing mechanism 400 for pairing and combination, and when the target battery cell of the second pairing mechanism 400 meets the first transport condition after pairing and combination, the target battery cell that meets the first transport condition of the second pairing mechanism 400 is moved to the first pairing mechanism 300, so as to Different handling conditions are used to sort and pair the target battery cells transmitted to the cache conveying mechanism 200, improve the sorting and pairing efficiency, and avoid the low sorting and pairing efficiency during discharge that affects the overall processing efficiency; by controlling the automatic sorting and pairing of the target battery cells, it is also possible to automatically fill multiple conveying stations of the first pairing mechanism 300. After the multiple conveying stations of the first pairing mechanism 300 are full, the first pairing mechanism 300 is controlled to automatically transfer the target battery cells of the multiple conveying stations to the next station, which can further improve the discharge pairing efficiency, meet different production capacity requirements, and avoid direct discharge when multiple conveying stations are not full, affecting the actual processing efficiency.

[0086] The embodiments corresponding to the discharge control method shown in this application are basically the same as the embodiments corresponding to the aforementioned material devices, so they will not be described one by one here.

[0087] In some embodiments, the discharge device further includes a second transfer mechanism 600 and a material output mechanism 730. The second transfer mechanism 600 is used to receive multiple battery cells from the previous inspection process. Before executing step S100 and controlling the first transfer mechanism 500 to move the target battery cells that meet the first handling condition of the buffer conveying mechanism 200 to the first pairing mechanism 300 and move the target battery cells that meet the second handling condition to the second pairing mechanism 400 for pairing and combination, the discharge control method further includes:

[0088] Step S011: calibrate the normal cells as target cells, and calibrate the abnormal cells as abnormal cells;

[0089] Step S012 : Control the second transfer mechanism 600 to move the abnormal battery cell to the material output mechanism 730 , and then move the target battery cell to the buffer conveying mechanism 200 .

[0090] In this application, a third transfer mechanism 820 is provided between the detection device 810 of the coating detection device and the second transfer mechanism 600. The discharge device also includes a code scanning device 11, which is provided between the previous detection process and the third transfer mechanism 820 to detect whether the multiple battery cells transferred from the previous detection process are normal. Referring to Figure 7, the discharge control method also includes the following steps:

[0091] Step S001, the detection device 810 discharges the material;

[0092] Step S002: After the third transplanting mechanism 820 receives the materials, the barcode scanning device 11 scans the received battery cells;

[0093] Step S003 : After determining whether the received battery cell is the target battery cell, the above steps S011 and S012 are executed in sequence.

[0094] The above-mentioned step S012 can be broken down into the following steps:

[0095] When the received cell is an abnormal cell, the following steps S0131 to S0132 are executed; when the received cell is a target cell, the following steps S0141 to S0142 are executed:

[0096] Step S0131: The second transfer mechanism 600 receives the abnormal battery cell and moves the abnormal battery cell to the material output mechanism 730;

[0097] Step S0132: The material output mechanism 730 transfers the abnormal battery cells to a target location;

[0098] Step S0141: The second transfer mechanism 600 receives the target battery cell and transfers the target battery cell to the buffer transfer mechanism 200 (via the second transfer mechanism 600).

[0099] Step S0142 : After determining whether the target battery cell of the buffer transfer mechanism 200 meets the first transport condition, execute the above-mentioned step S100 .

[0100] The above step S100 can be refined into:

[0101] When the buffer transfer mechanism 200 meets the target battery cell of the first transport condition, the following steps S111 are performed:

[0102] Step S111: After the first transfer mechanism 500 moves the target battery cell (which meets the first transport condition of the buffer transfer mechanism 200) to the first pairing mechanism 300, step S300 is executed;

[0103] When the buffer transfer mechanism 200 does not meet the target battery cell of the first transport condition, the following steps S121 are performed:

[0104] In step S121 , the first transporting mechanism 500 moves the target battery cell (the target battery cell meeting the second transport condition or other) to the second pairing mechanism 400 for pairing and combination, and then performs step S200 .

[0105] In some embodiments, step S200 may be further refined as follows:

[0106] Step S210: Determine whether the target battery cell of the second pairing mechanism 400 meets the first transport condition:

[0107] When the target battery cell pairing combination of the second pairing mechanism 400 meets the first transport condition, the above-mentioned step S111 is executed;

[0108] When the target battery cell pairing combination of the second pairing mechanism 400 does not meet the first transport condition, the above steps S001 to S100 are repeatedly executed.

[0109] In some embodiments, step S300 may be further refined as follows:

[0110] Step S310: Determine whether the target battery cells are fully loaded into the plurality of transfer stations of the first pairing mechanism 300.

[0111] When the target battery cells fill up the multiple transfer stations of the first pairing mechanism 300 , the following step S320 is executed; when the target battery cells do not fill up the multiple transfer stations of the first pairing mechanism 300 , the above steps S001 to S100 are repeated;

[0112] In step S320 , the first pairing mechanism 300 transfers the target cells of the plurality of transfer stations to the next station.

[0113] In the present application, before sorting and pairing, the target battery cells that are tested normally and the abnormal battery cells that are tested abnormally are first screened out from the multiple battery cells transmitted in the previous inspection process. After the abnormal battery cells are directly transferred through the material output mechanism 730, the target battery cells are received through the cache transmission mechanism 200 to achieve accurate pairing and transmission of the target battery cells. In this way, the positioning accuracy of the battery cells in the discharge logistics line can be optimized, and the discharge efficiency and discharge quality can be improved.

[0114] In some embodiments, before executing step S100 and controlling the first transfer mechanism 500 to move the target battery cells meeting the first transport condition of the buffer conveying mechanism 200 to the first pairing mechanism 300 and to move the target battery cells meeting the second transport condition to the second pairing mechanism 400 for pairing and combination, the discharge control method further includes:

[0115] Step S021: When there is only one target battery cell, determine that the target battery cell is a target battery cell that meets the second transport condition;

[0116] Step S022: When there are multiple target cells, at least two target cells located at adjacent transfer stations among the multiple target cells are determined, in a predetermined order, to be target cells that meet the first handling condition, and the remaining target cells are determined to be target cells that meet the second handling condition. Prior to sorting and pairing, the target cells that meet the first handling condition and the target cells that meet the second handling condition are screened out to optimize the positioning accuracy of each target cell during the unloading process and further improve processing efficiency.

[0117] In some embodiments of the present application, the cache conveying mechanism 200 and the first pairing mechanism 300 have four conveying stations, the first transfer mechanism 500 has two conveying stations, and the second pairing mechanism 400 has two or more conveying stations.

[0118] 8 , the number of target cells of the cache transfer mechanism 200 is determined, with the Y direction in FIG1 being the first direction, the X direction in FIG1 being the second direction, the first guide rail 501 of the first transfer mechanism 500 extending along the first direction, and the direction in which the first carrier 502 moves from the cache transfer mechanism 200 to the first pairing mechanism 300 along the first guide rail 501 being the left-to-right direction.

[0119] Before executing the above step S0142 of determining whether the target battery cells of the buffer transfer mechanism 200 meet the first transport condition, the process further includes step S112 of determining the number of the target battery cells.

[0120] The above step S100 can be refined into:

[0121] Step S1121: When the number of target cells is four, execute the following step S101;

[0122] Step S1122: When the number of target cells is three, execute the following steps S1021 to S1022;

[0123] Step S1123: When there are two target cells, execute the following steps S1031 to S1033;

[0124] Step S1124: When there is only one target cell, execute the following step S104.

[0125] When there are four target battery cells, it is determined that the four target battery cells meet the first transport condition, step S101 is executed, and the first transport mechanism 500 moves the four parallel target battery cells to the first pairing mechanism 300 in sequence from left to right, and then step S300 is executed. Specifically, the first transport mechanism 500 first moves the target battery cells of the two transfer positions set near the left side to the two transfer positions set near the left side of the first pairing mechanism 300 (or, when the two transfer positions set near the left side of the first pairing mechanism 300 are full, it moves them to the two transfer positions set near the right side of the first pairing mechanism 300 and then executes step S300), and then moves the target battery cells of the two transfer positions set near the right side of the first transport mechanism 500 to the two transfer positions set near the right side of the first pairing mechanism 300 (or, when step S300 is executed simultaneously, the target battery cells of the two transfer positions set near the right side of the first transport mechanism 500 are moved to the two transfer positions set near the left side of the first pairing mechanism 300).

[0126] The above step S300 can be further refined as follows:

[0127] Step S301: After the target battery cells are placed in the multiple transfer stations of the first pairing mechanism 300, the first pairing mechanism 300 transfers the target battery cells in the multiple transfer stations to the discharging mechanism 720 through the discharging and transferring mechanism 710;

[0128] Step S302: the discharging mechanism 720 receives the material.

[0129] The implementation of step S301 shown here refers to the corresponding embodiments of the aforementioned material device and the aforementioned steps S310 and S320, which will not be described in detail here.

[0130] When the target number of cells is three, perform the following steps:

[0131] Step S1021: The first transplanting mechanism 500 moves two parallel target cells to the first pairing mechanism 300 in order from left to right.

[0132] In step S1022 , the first transplanting mechanism 500 moves another target battery cell to the second pairing mechanism 400 .

[0133] Specifically, the first transferring mechanism 500 moves the target battery cells of the two transfer positions arranged near the left side and in parallel to the two transfer positions arranged near the left side of the first pairing mechanism 300 (when the two transfer positions arranged near the left side of the first pairing mechanism 300 are full, it moves to the two transfer positions arranged near the right side of the first pairing mechanism 300), and then moves the other target battery cells of the cache transfer mechanism 200 to the transfer position arranged near the left side of the second pairing mechanism 400 through the first transferring mechanism 500 (when the transfer positions arranged near the left side of the second pairing mechanism 400 are full, it is repeated in sequence to place the target battery cells in the idle transfer positions of the second pairing mechanism 400).

[0134] After executing the above steps S1021 and S1022, step S300 is executed. After executing the above step S1022, the position of the target cell of the second pairing mechanism 400 is determined to execute step S200. Step S200 can be further refined as follows:

[0135] Step S201: Determine that the second pairing mechanism 400 has two target battery cells located at adjacent transfer stations;

[0136] In step S202 , the first transplanting mechanism 500 moves the two target cells of the second pairing mechanism to the first pairing mechanism 300 .

[0137] In addition to determining that the second pairing mechanism 400 has two target battery cells located at adjacent transfer stations, step S201 may also include but is not limited to the number of target battery cells of the second pairing mechanism 400 being no less than the number of idle transfer stations of the first pairing mechanism 300, the transfer stations of the second pairing mechanism 400 being full, etc.

[0138] When there are two target cells, perform the following steps:

[0139] S1031 , determining whether two target battery cells are located at adjacent transfer stations; if so, executing step S1032 ; if not, executing step S1033 .

[0140] Step S1032: The first transplanting mechanism 500 moves the two parallel target cells to the first pairing mechanism 300 in order from left to right;

[0141] Step S1033: The first transplanting mechanism 500 moves the two target battery cells to the second pairing mechanism 400 in sequence from left to right.

[0142] After executing steps S1031 , S1032 , and S1033 , step S300 is executed. After executing step S1033 , the position of the target cell of the second pairing mechanism 400 is determined to execute steps S201 and S202 .

[0143] When there is only one target cell, perform the following steps:

[0144] In step S104 , the first transplanting mechanism 500 moves the target battery cell to the second pairing mechanism 400 .

[0145] Furthermore, after executing the above step S104 , the position of the target cell of the second pairing mechanism 400 is determined to execute the above steps S201 and S202 .
