[0002] In the production process of photovoltaic cells (such as Topcon cells), a laser processing step is required. The laser processing step usually uses a laser to drill holes or grooves on the surface of the cell (such as a silicon wafer) to penetrate part of the thin film layer (such as an Al2O3 layer, a SiNx layer) and expose the silicon substrate, so that the back electric field can contact the silicon substrate through the holes or grooves on the thin film layer.

[0003] The laser processing procedure of battery cells involves loading the battery cells into the processing station and unloading the battery cells out of the processing station.

[0060] The laser processing procedure of battery cells involves loading the battery cells into the processing station and unloading the battery cells out of the processing station. During the loading and unloading process, the laser processing operation will be suspended, which limits the production rhythm of the battery cells and results in low mass production efficiency of the battery cells.

[0061] In order to solve the above problems, the present invention proposes a battery cell laser processing system, which can realize the laser processing operation of a part of the battery cells and the loading and unloading operation of another part of the battery cells at the same time through the alternating actions of the first laser and the second laser and the coordination between the laser and the rotating arm, so that the execution time periods of the laser processing operation and the loading and unloading operation of the battery cells can be reasonably allocated, thereby reducing the time wasted in the laser processing procedure due to waiting for laser processing or waiting for loading and unloading, and laying a structural foundation for speeding up the laser processing production rhythm of battery cells and improving the mass production efficiency of battery cells.

[0062] See also Figures 1 to 3 In one embodiment of the present invention, the battery cell laser processing system includes a rotating arm 1, a first processing station 2, a second processing station 3, a first laser (not shown in the figure), a second laser (not shown in the figure), a loading device 4 and a unloading device 5. Among them, in addition to being used to accommodate the battery cell 6 to be processed, the first processing station 2 and the second processing station 3 are usually equipped with corresponding fixtures and positioning devices to fix the battery cell 6 to ensure that the first laser and the second laser can stably and accurately perform laser processing on the battery cell 6 on the corresponding processing station; in addition, the first processing station 2 and the second processing station 3 can also provide necessary environmental control, such as controlling temperature, humidity and other conditions to ensure the quality of laser processing; further, the first processing station 2 and the second processing station 3 can also be equipped with corresponding sensor units to monitor various parameters of the battery cell 6 during the laser processing process.

[0063] The rotating arm 1 is provided with a material taking end 101; the material taking end 101 is used to transfer the battery cell 6 to be processed in the loading station (not shown in the figure) to the first processing station 2 or the second processing station 3 as the rotating arm 1 rotates, and the material taking end 101 is used to transfer the battery cell 6 processed in the first processing station 2 or the second processing station 3 to the unloading station (not shown in the figure) as the rotating arm 1 rotates;

[0064] The first laser is used to perform laser processing on the battery cell 6 transferred to the first processing station 2;

[0065] The second laser is used to perform laser processing on the battery cell 6 transferred to the second processing station 3;

[0066] The loading device 4 is used to transport the battery cells 6 to be processed to the loading station;

[0067] The unloading device 5 is used to transport the battery cells 6 processed in the unloading station to the outside.

[0068] In this embodiment, the rotating arm 1 can be used as follows Figure 3 The long strip arm body shown can be driven by a driving device such as a motor and a rotating cylinder; the material picking end 101 can be set on an end of the rotating arm 1 away from the rotation center, and the material picking end 101 can adopt grabbing, clamping, sucking, hanging and other material picking methods to achieve the fixation and transfer of the battery cell 6, and the above-mentioned material picking methods can be completed with the help of clamps, pneumatic fingers, buckles, suction cups, magnets, hooks and other devices, which are not limited here.

[0069] The first laser and the second laser are used to perform laser processing operations such as drilling and grooving on the surface of the battery cell 6 by laser. The loading device 4 and the unloading device 5 can adopt a conveyor line composed of belts, conveyor chains, motors, rollers and other devices; the loading station can be set at one end of the loading device 4, and the other end of the loading device 4 is used to feed the battery cell 6 to be processed; the unloading station can be set at one end of the unloading device 5, and the other end of the unloading device 5 can be docked with the collection area or the target station of the next process, so as to transport the processed battery cell 6 to the collection area for unified collection, or directly transport the processed battery cell 6 to the target station for the next process.

[0070] Based on the above settings, the first laser and the second laser can be configured to alternately perform laser processing on the battery cells 6 transferred to the corresponding processing stations; that is, when the first laser is performing laser processing on the battery cells 6 of the first processing station 2, the second laser can be in a waiting state, at which time the rotating arm 1 can perform a loading operation of transferring the battery cells 6 to be processed in the loading station to the second processing station 3, or perform a unloading operation of transferring the battery cells 6 processed in the second processing station 3 to the unloading station; similarly, when the second laser is performing laser processing on the battery cells 6 of the second processing station 3, the first laser can be in a waiting state, at which time the rotating arm 1 can perform a loading operation of transferring the battery cells 6 to be processed in the loading station to the first processing station 2, or perform a unloading operation of transferring the battery cells 6 processed in the first processing station 2 to the unloading station. In this way, through the alternating actions of the first laser and the second laser and the coordination between the laser and the rotating arm 1, the laser processing operation of a part of the battery cells 6 and the loading and unloading operation of another part of the battery cells 6 can be carried out simultaneously, so that the execution time periods of the laser processing operation and the loading and unloading operation of the battery cells 6 can be reasonably allocated, thereby reducing the time waste caused by waiting for laser processing or waiting for loading and unloading in the laser processing procedure, and laying a structural foundation for speeding up the laser processing production rhythm of the battery cells 6 and improving the mass production efficiency of the battery cells 6.

[0071] It should be noted that the "interleaving" described in this embodiment refers to the interleaving in time. The interleaving state includes the state in which one laser completes processing and then another laser starts processing, and the state in which one laser starts processing after a period of time. It can be flexibly set according to production needs during the specific implementation process.

[0072] Optionally, refer to Figures 1 to 3 One end of the rotating arm 1 rotates around a first axis (not shown in the figure) driven by a first driving assembly 7; the battery cell laser processing system also includes a swing arm 8, the middle part of the swing arm 8 is rotatably connected to the other end of the rotating arm 1 around a second axis (not shown in the figure); the material picking end 101 includes at least two material picking parts 1011, and the at least two material picking parts 1011 are distributed at both ends of the swing arm 8, and each material picking part 1011 is used to transfer at least one battery cell 6.

[0073] Specifically, the first drive assembly 7 may include a drive device such as a motor and a cylinder, as well as a matching reduction mechanism and a transmission mechanism. The swing arm 8 may be rotatably connected to the rotating arm 1 by means of a seat bearing; wherein, the rotation angle of the swing arm 8 relative to the rotating arm 1 may be adjusted manually, and after the swing arm 8 is rotated into place, the swing arm 8 may be fixed at the current angular position by fastening devices such as screws, buckles, spring plungers, etc., or the swing arm 8 may be driven to rotate by a drive device such as a motor and a cylinder, and the swing arm 8 rotated into place may be fixed at the current angular position based on the self-locking property of the drive device, which is not limited here. By rotating the swing arm 8 relative to the rotating arm 1, the position adjustment of the material picking end 101 relative to the rotating arm 1 is realized, so that the material picking end 101 can reach the corresponding workstation more accurately with the rotation of the rotating arm 1.

[0074] The material picking part 1011 can be understood as the part on the material picking end 101 that is directly used for picking and placing the battery cell 6. When the material picking end 101 includes at least two material picking parts 1011, the material picking and placing operation can be performed on at least two battery cells 6 in the corresponding workstation at the same time, and the transfer of at least two battery cells 6 can be completed at one time, thereby improving the laser processing production efficiency of the battery cell 6; wherein, taking the setting of two material picking parts 1011 as an example, one of the material picking parts 1011 can be set at one end of the swing arm 8, and the other material picking part 1011 can be set at the other end of the swing arm 8. Correspondingly, at least two accommodating areas for accommodating battery cells 6 should be set in each workstation, and each accommodating area is used to accommodate one battery cell 6; the first laser and the second laser should be configured to perform laser processing operations on at least two battery cells 6 at the same time, and the loading device 4 and the unloading device 5 should be configured to convey at least two battery cells 6 at the same time.

[0075] On the basis of the above embodiment, since at least two material-collecting parts 1011 are provided on the rotating arm 1, during the rotation of the rotating arm 1 around the first axis, if the positions of the at least two material-collecting parts 1011 relative to the rotating arm 1 remain unchanged, that is, the angle of the swing arm 8 relative to the rotating arm 1 remains unchanged, then the absolute angles of the at least two material-collecting parts 1011 in the laser processing system will continue to change with the rotation of the rotating arm 1. Specifically, taking the example of providing a material-collecting part 1011 at each end of the swing arm 8, when the extending direction of the rotating arm 1 is Figure 2When it is set along the left-right direction in the top-down perspective shown, the extension direction of the swing arm 8 is also set along the left-right direction, and the two material-collecting parts 1011 are arranged at intervals along the left-right direction; when the rotating arm 1 rotates a certain angle, the extension direction of the rotating arm 1 becomes obliquely upward or obliquely downward. If the angle of the swing arm 8 relative to the rotating arm 1 remains unchanged, the extension direction of the swing arm 8 will also become obliquely upward or obliquely downward with the rotation of the rotating arm 1. At this time, the two material-collecting parts 1011 will become arranged at intervals along the obliquely upward or obliquely downward direction; if the two accommodating areas for accommodating the battery cells 6 in each workstation are arranged along the left-right direction, then the two battery cells 6 arranged at intervals along the obliquely upward or obliquely downward direction on the two material-collecting parts 1011 obviously cannot be placed one-to-one in the two accommodating areas of the corresponding workstation.

[0076] In order to solve the above problems, the following embodiments are proposed:

[0077] Reference Figure 1 and Figure 2 The battery cell laser processing system also includes a second drive component 9; while the first drive component 7 drives the rotating arm 1 to rotate around the first axis, the second drive component 9 is used to drive the swing arm 8 to rotate around the second axis relative to the rotating arm 1; the first axis is parallel to the second axis.

[0078] Diagrammatically, the first axis and the second axis can be set to be perpendicular to the ground, and the first processing station 2, the second processing station 3, the loading station, and the unloading station can be arranged at intervals around the rotating arm 1 on the horizontal plane, so that the rotating arm 1 can make the material picking end 101 reach each station along the circumferential direction through a simple rotation action, thereby simplifying the structure of the laser processing system.

[0079] In this embodiment, by setting up a second driving component 9, the swing arm 8 can be driven to rotate around the second axis in real time during the rotation of the rotating arm 1 around the first axis, so as to realize real-time adjustment of the angle of the swing arm 8 relative to the rotating arm 1, so that the absolute angle of at least two material-retrieving parts 1011 in the laser processing system can be unaffected by the rotation of the rotating arm 1, so that when the rotating arm 1 rotates to the corresponding workstation, it can be ensured that at least two material-retrieving parts 1011 can rotate with the swing arm 8 to a position opposite to at least two accommodating areas in the corresponding workstation, so that at least two battery cells 6 on the swing arm 8 can be accurately placed in the corresponding accommodating areas; moreover, the arrangement direction of each accommodating area in each workstation can be uniformly set, for example, Figure 2 The arrangement shown is arranged along the left and right direction, and there is no need to make differential adjustments according to the different rotation angles of the rotating arm 1. Based on the above arrangement, the accuracy of the transfer operation of the battery sheet 6 and the applicability of the laser processing system are improved.

[0080] Among them, the second drive assembly 9 may include a drive device such as a motor, a cylinder, and a matching reduction mechanism and a transmission mechanism. The first drive assembly 7 and the second drive assembly 9 may be electrically connected to the same main control module, so that the rotation angle, rotation node, rotation speed and other parameters of the first drive assembly 7 and the second drive assembly 9 can be uniformly regulated through a preset program in the main control module, so that the rotation action of the first drive assembly 7 can be coordinated with the rotation action of the second drive assembly 9. Preferably, the action of the second drive assembly 9 driving the swing arm 8 to rotate should be completed before or at the same time as the action of the first drive assembly 7 driving the rotating arm 1 to rotate is completed, so as to avoid the need to wait for the swing arm 8 to rotate into place after the rotating arm 1 rotates into place, thereby further improving the laser processing production efficiency of the battery cell 6.

[0081] Optionally, refer to Figures 1 to 3 The first driving assembly 7 includes a first motor 701 and a first reduction gear 702 ; the driving end of the first motor 701 is connected to the input end of the first reduction gear 702 , and the output end of the first reduction gear 702 is connected to one end of the rotating arm 1 .

[0082] Optionally, refer to Figures 1 to 3 The second driving assembly 9 includes a second motor 901 and a second reduction gear 902 ; the driving end of the second motor 901 is connected to the input end of the second reduction gear 902 , and the output end of the second reduction gear 902 is connected to the middle part of the swing arm 8 .

[0083] Specifically, by providing the first reduction gear 702 and the second reduction gear 902, the rotation speed of the first motor 701 and the second motor 901 can be reduced and the torque can be increased, so that the swing arm 1 and the swing arm 8 can stably rotate in a preset manner under load. Figure 3 As shown, the end of the swing arm 8 directly mounted on the swing arm 1 does not need to be mounted on the rotation center of the swing arm 1 and transmitted through a transmission member such as a belt, thereby improving the driving accuracy and stability in a direct drive manner. Correspondingly, the second reduction device 902 can be set as a planetary reducer, which has the advantages of light weight, small size, large transmission ratio range, and smooth transmission. It can avoid that the end of the swing arm 8 on the swing arm 1 takes up too much space and interferes with other devices during the rotation process, and can also avoid the problem of difficulty in rotating the swing arm 1 due to its excessive weight.

[0084] Optionally, refer to Figure 1 and Figure 2, and also includes a third driving component 10, which is used to move the battery cell 6 to be processed in the first processing station 2 along the direction away from the rotating arm 1 to the processing area of ​​the first laser, and the third driving component 10 is used to move the battery cell 6 processed in the processing area of ​​the first laser to the first processing station 2.

[0085] In this embodiment, the battery cell 6 is not directly laser processed at the first processing station 2, but the first laser is set at a position with a spacing from the first processing station 2. In actual operation, the battery cell 6 to be processed in the first processing station 2 is first transferred to the processing area of ​​the first laser by the third drive assembly 10, and then the battery cell 6 is laser processed by the first laser; in this way, the interference between the first laser and the rotating arm 1 can be avoided, and the adverse effects between the laser processing operation and the material picking and placing transfer operation can be prevented. Specifically, taking the first processing station 2, the second processing station 3, the loading station, and the unloading station as an example, the first laser can be set at a position radially away from the rotation center of the rotating arm 1 relative to the first processing station 2. Among them, the third drive assembly 10 may include a drive device such as a motor and a cylinder, and a matching reduction mechanism and a transmission mechanism, and the battery cell 6 can be transferred between the first processing station 2 and the processing area of ​​the first laser by translation or rotation, which is not limited here.

[0086] Optionally, refer to Figure 1 and Figure 2 , and also includes a fourth drive component 11, which is used to move the battery cell 6 to be processed in the second processing station 3 along the direction away from the rotating arm 1 to the processing area of ​​the second laser, and the fourth drive component 11 is used to move the battery cell 6 processed in the processing area of ​​the second laser to the second processing station 3.

[0087] In this embodiment, the battery cell 6 is not directly laser processed at the second processing station 3, but the second laser is set at a position with a spacing from the second processing station 3. In actual operation, the battery cell 6 to be processed in the second processing station 3 is first transferred to the processing area of ​​the second laser by the fourth drive component 11, and then the battery cell 6 is laser processed by the second laser; in this way, the interference between the second laser and the rotating arm 1 can be avoided, and the adverse effects between the laser processing operation and the material picking and placing transfer operation can be prevented. Specifically, taking the first processing station 2, the second processing station 3, the loading station, and the unloading station as an example, the second laser can be set at a position radially away from the rotation center of the rotating arm 1 relative to the second processing station 3. Among them, the fourth drive component 11 may include a drive device such as a motor and a cylinder, and a matching reduction mechanism and a transmission mechanism, and the battery cell 6 can be transferred between the second processing station 3 and the processing area of ​​the second laser by translation or rotation, which is not limited here.

[0088] Optionally, refer to Figure 1 and Figure 2 , also includes a first support frame 12, the middle part of the first support frame 12 is connected to the third drive assembly 10; the first processing station 2 includes a first sub-station 201 and a second sub-station 202, the first sub-station 201 is arranged on one side of the first support frame 12, and the second sub-station 202 is arranged on the other side of the first support frame 12, and the first sub-station 201 and the second sub-station 202 are used to place the battery cell 6; the third drive assembly 10 is used to drive the first support frame 12 to rotate, so that one of the first sub-station 201 and the second sub-station 202 enters the processing area of ​​the first laser, and at the same time, the other one of the first sub-station 201 and the second sub-station 202 enters the material picking and placing area of ​​the material picking end 101.

[0089] Specifically, Figure 2 As shown, the third driving assembly 10 can drive the first support frame 12 to rotate to ensure that when the first sub-station 201 rotates with the first support frame 12 to the processing area of ​​the first laser, the second sub-station 202 can simultaneously rotate with the first support frame 12 to the material picking and placing area of ​​the material picking end 101 at the first processing station 2; and to ensure that when the second sub-station 202 rotates with the first support frame 12 to the processing area of ​​the first laser, the first sub-station 201 can simultaneously rotate with the first support frame 12 to the material picking and placing area of ​​the material picking end 101 at the first processing station 2.

[0090] Based on the above settings, when the first sub-station 201 is located in the material picking and placing area of ​​the material picking end 101, the material picking end 101 can place the battery cell 6 to be processed in the first sub-station 201, and then the third driving component 10 drives the first supporting frame 12 to rotate, so as to drive the first sub-station 201 to enter the processing area of ​​the first laser, and at the same time drive the vacant second sub-station 202 to enter the material picking and placing area of ​​the material picking end 101, at this time, the first laser can perform laser processing on the battery cell 6 in the first sub-station 201; when the material picking end 101 subsequently transfers another battery cell 6 to be processed to the first processing station 2, even if the laser processing of the battery cell 6 in the first sub-station 201 has not been completed, the material picking end 101 can still place the battery cell 6 to be processed it carries in the vacant second sub-station 202. In the second sub-station 202, the material taking end 101 can then perform subsequent material taking and discharging transfer operations without waiting for the battery cell 6 in the first sub-station 201 to be processed before discharging; when the battery cell 6 in the first sub-station 201 is processed, the third driving component 10 drives the first support frame 12 to rotate again to drive the first sub-station 201 to enter the material taking and discharging area of ​​the material taking end 101, and at the same time drive the second sub-station 202 to enter the processing area of ​​the first laser, at this time the first laser can perform laser processing on the battery cell 6 in the second sub-station 202, and when the material taking end 101 arrives at the first processing station 2 again later, the material taking end 101 can take away the processed battery cell 6 in the first sub-station 201 and perform material unloading operations, and so on. Through the above operations, the waiting time in the laser processing production process can be further compressed, so that the execution time periods of the laser processing operation and the loading and unloading operation of the battery cell 6 can be more reasonably allocated, thereby further improving the mass production efficiency of the battery cell 6.

[0091] Optionally, refer to Figure 1 and Figure 2 , and also includes a second support frame 13, the middle part of the second support frame 13 is connected to the fourth drive assembly 11; the second processing station 3 includes a third sub-station 301 and a fourth sub-station 302, the third sub-station 301 is arranged on one side of the second support frame 13, and the fourth sub-station 302 is arranged on the other side of the second support frame 13, and the third sub-station 301 and the fourth sub-station 302 are used to place the battery cell 6; the fourth drive assembly 11 is used to drive the second support frame 13 to rotate, so that one of the third sub-station 301 and the fourth sub-station 302 enters the processing area of ​​the second laser, and at the same time, the other one of the third sub-station 301 and the fourth sub-station 302 enters the material picking and placing area of ​​the material picking end 101.

[0092] Specifically, Figure 2As shown, the fourth driving assembly 11 can drive the second support frame 13 to rotate to ensure that when the third sub-station 301 rotates with the second support frame 13 to the processing area of ​​the second laser, the fourth sub-station 302 can simultaneously rotate with the second support frame 13 to the material picking and placing area of ​​the material picking end 101 at the second processing station 3; and to ensure that when the fourth sub-station 302 rotates with the second support frame 13 to the processing area of ​​the second laser, the third sub-station 301 can simultaneously rotate with the second support frame 13 to the material picking and placing area of ​​the material picking end 101 at the second processing station 3.

[0093] Based on the above settings, when the third sub-station 301 is located in the material picking and placing area of ​​the material picking end 101, the material picking end 101 can place the battery cell 6 to be processed in the third sub-station 301, and then the fourth driving component 11 drives the second support frame 13 to rotate, so as to drive the third sub-station 301 to enter the processing area of ​​the second laser, and at the same time drive the vacant fourth sub-station 302 to enter the material picking and placing area of ​​the material picking end 101, at this time, the second laser can perform laser processing on the battery cell 6 in the third sub-station 301; when the material picking end 101 subsequently transfers another battery cell 6 to be processed to the second processing station 3, even if the laser processing of the battery cell 6 in the third sub-station 301 has not been completed, the material picking end 101 can still place the battery cell 6 to be processed it carries in the vacant fourth sub-station 302. In the fourth sub-station 302, the material taking end 101 can then perform subsequent material taking and discharging transfer operations without waiting for the battery cell 6 in the third sub-station 301 to be processed before discharging; when the battery cell 6 in the third sub-station 301 is processed, the fourth driving component 11 drives the second support frame 13 to rotate again to drive the third sub-station 301 to enter the material taking and discharging area of ​​the material taking end 101, and at the same time drive the fourth sub-station 302 to enter the processing area of ​​the second laser, at this time, the second laser can perform laser processing on the battery cell 6 in the fourth sub-station 302, and when the material taking end 101 arrives at the second processing station 3 again later, the material taking end 101 can take away the processed battery cell 6 in the third sub-station 301 and perform material unloading operations, and so on. Through the above operations, the waiting time in the laser processing production process can be further compressed, so that the execution time periods of the laser processing operation and the loading and unloading operation of the battery cell 6 can be more reasonably allocated, thereby further improving the mass production efficiency of the battery cell 6.

[0094] Optionally, refer to Figures 1 to 3, the material picking end 101 is configured as a material picking suction cup; more specifically, when the material picking end 101 includes at least two material picking parts 1011, each material picking part 1011 is a material picking suction cup. The material picking suction cup can realize the material picking operation of the battery cell 6 by negative pressure suction. The negative pressure suction method can minimize the rigid collision and scratching of the battery cell 6 during the material picking process, thereby avoiding damage to the battery cell 6 and affecting its performance. Preferably, the material picking suction cup can adopt a Bernoulli suction cup, which can transfer the battery cell 6 without directly contacting the surface of the battery cell 6, thereby reducing the physical damage and contamination caused to the surface of the battery cell 6; in addition, the Bernoulli suction cup can accurately control the position of the battery cell 6, and does not require the surface of the battery cell 6 to be completely flat. Even if the surface of the battery cell 6 has a certain degree of roughness or irregularity, the Bernoulli suction cup can effectively complete the material picking and transfer operations.

[0095] See also Figures 1 to 4 The present invention further proposes a battery cell processing and transfer method, which is implemented by using the battery cell laser processing system in any of the above embodiments; the battery cell processing and transfer method comprises the following steps:

[0096] S1, the rotating arm 1 rotates along a first preset path to sequentially transfer the battery cells 6 to be processed in the loading station to the first processing station 2 and the second processing station 3 through the material taking end 101;

[0097] S2, when the first laser completes laser processing of the battery cell at the first processing station 2, the rotating arm 1 rotates along the second preset path to transfer the battery cell 6 at the first processing station 2 to the unloading station through the material taking end 101;

[0098] S3, the rotating arm 1 rotates along the third preset path to transfer the battery cell 6 to be processed in the loading station to the first processing station 2 through the material taking end 101;

[0099] S4, when the second laser completes laser processing of the battery cell at the second processing station 3, the rotating arm 1 rotates along the fourth preset path to transfer the battery cell 6 at the second processing station 3 to the unloading station through the material taking end 101;

[0100] S5, the rotating arm 1 rotates along the fifth preset path to transfer the battery cell 6 to be processed in the loading station to the second processing station 3 through the material taking end 101;

[0101] S6, repeat the above steps S2 to S5.

[0102] In this embodiment, the first preset path, the second preset path, the third preset path, the fourth preset path, and the fifth preset path may all include one or more rotation trajectories. For example, the arm 1 rotates along the first preset path, which may be a forward rotation of a certain angle or a reverse rotation of a certain angle, or the arm 1 rotates forward a certain angle and then reversely a certain angle, or the arm 1 rotates reversely a certain angle and then rotates forward a certain angle; the arm 1 rotates along other preset paths in the same manner. In actual operation, it is only necessary to ensure that the arm 1 can complete the material placement and transfer operations of the battery cell 6 through the corresponding rotation action, and no specific limitation is made here.

[0103] The battery cell processing and transfer method provided in this embodiment adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought by the technical solutions of the above embodiments, that is, through the rotation of the rotating arm 1, the material picking end 101 on the rotating arm 1 can drive the battery cell 6 to be orderly transferred between the first processing station 2, the second processing station 3, the loading station, and the unloading station, and the first laser and the second laser can alternately perform laser processing on the battery cell 6 transferred to the corresponding processing station; that is, when the first laser is laser processing the battery cell 6 in the first processing station 2, the second laser can be in a waiting state, and the rotating arm 1 can perform a loading operation of transferring the battery cell 6 to be processed in the loading station to the second processing station 3, or perform a unloading operation of transferring the battery cell 6 processed in the second processing station 3 to the unloading station; similarly, When the second laser is performing laser processing on the battery cell 6 in the second processing station 3, the first laser may be in a waiting state, and the rotating arm 1 may perform a loading operation of transferring the battery cell 6 to be processed in the loading station to the first processing station 2, or perform an unloading operation of transferring the battery cell 6 processed in the first processing station 2 to the unloading station; in this way, through the alternating action of the first laser and the second laser and the coordination between the laser and the rotating arm 1, the laser processing operation of a part of the battery cells 6 and the loading and unloading operations of another part of the battery cells 6 can be carried out simultaneously, so that the execution time periods of the laser processing operation and the loading and unloading operations of the battery cells 6 can be reasonably allocated, thereby reducing the time waste caused by waiting for laser processing or waiting for loading and unloading in the laser processing process, thereby speeding up the laser processing production rhythm of the battery cells 6 and improving the mass production efficiency of the battery cells 6.

[0104] Optionally, refer to Figures 1 to 5 The loading station, the unloading station, the first processing station 2, and the second processing station 3 are arranged at intervals around the rotating arm 1; steps S2 to S5 include:

[0105] S21, when the first laser completes laser processing of the battery cell 6 of the first processing station 2, the battery cell 6 of the first processing station 2 is taken out through the material taking end 101;

[0106] S22, the rotating arm 1 rotates in a first clockwise direction by a first angle, and then places the battery cell 6 carried by the material taking end 101 on the unloading station;

[0107] S31, the rotating arm 1 rotates in a second clockwise direction by a second angle, and then the material taking end 101 takes the battery cell 6 at the loading station;

[0108] S32, the rotating arm 1 rotates in a third clockwise direction by a third angle, and then places the battery cell 6 carried by the material taking end 101 on the first processing station 2;

[0109] S41, when the second laser completes laser processing of the battery cell 6 of the second processing station 3, the rotating arm 1 rotates by a fourth angle in a fourth clockwise direction, and then performs a material picking operation on the battery cell 6 of the second processing station 3 through the material picking end 101;

[0110] S42, the rotating arm 1 rotates in a fifth clockwise direction by a fifth angle, and then places the battery cell 6 carried by the material taking end 101 on the unloading station;

[0111] S51, the rotating arm 1 rotates in a sixth clockwise direction by a sixth angle, and then the material taking end 101 takes the battery cell 6 at the loading station;

[0112] S52, the rotating arm 1 rotates in a seventh clockwise direction by a seventh angle, and then places the battery cell 6 carried by the material taking end 101 on the second processing station 3;

[0113] S53, the rotating arm 1 rotates by an eighth angle in the eighth clockwise direction so that the material picking suction cup reaches the first processing station 2.

[0114] In this embodiment, the loading station, unloading station, first processing station 2, and second processing station 3 arranged around the rotating arm 1 are all located within the rotation coverage of the rotating arm 1. Therefore, the rotating arm 1 can drive the material picking end 101 to each station to perform material picking and placing operations through a single rotation action, thereby simplifying the structure of the laser processing system.

[0115] In this embodiment, each clockwise direction can be clockwise or counterclockwise, which can be set according to the arrangement of each workstation. Figure 5 As shown in the example, the first processing station 2 is located at the upper left side of the rotating arm 1, the second processing station 3 is located at the lower left side of the rotating arm 1, the unloading station is located at the upper right side of the rotating arm 1, and the loading station is located at the lower right side of the rotating arm 1. The material picking end 101 can be set as a material picking suction cup, and the above steps S21 to S53 are specifically as follows:

[0116] When the first laser completes laser processing of the battery cell 6 at the first processing station 2, the battery cell 6 at the first processing station 2 is sucked up by the material-picking suction cup; the rotating arm 1 rotates clockwise by a first angle, and then places the sucked battery cell 6 at the unloading station by the material-picking suction cup; the rotating arm 1 continues to rotate clockwise by a second angle, and then sucks up the battery cell 6 at the loading station by the material-picking suction cup; the rotating arm 1 continues to rotate clockwise or counterclockwise by a third angle, and then places the sucked battery cell 6 at the first processing station 2 by the material-picking suction cup; when the second laser completes laser processing of the battery cell 6 at the second processing station 3, the rotating arm 1 rotates counterclockwise by a fourth angle , and then the battery cell 6 of the second processing station 3 is sucked by the material picking suction cup; the rotating arm 1 continues to rotate clockwise or counterclockwise to the fifth angle, and then the sucked battery cell 6 is placed on the unloading station through the material picking suction cup; the rotating arm 1 continues to rotate clockwise to the sixth angle, and then the battery cell 6 of the loading station is sucked by the material picking suction cup; the rotating arm 1 continues to rotate clockwise to the seventh angle, and then the sucked battery cell 6 is placed on the second processing station 3 through the material picking suction cup; the rotating arm 1 continues to rotate clockwise to the eighth angle, so that the material picking suction cup reaches the first processing station 2 and subsequently sucks the processed battery cell 6; the above steps are then repeated.

[0117] Based on the above arrangement, the corresponding laser processing operation and loading and unloading operation can be completed while minimizing the rotation distance of the rotating arm 1, thereby further improving the batch production efficiency of the battery cells 6.

[0118] Optionally, refer to Figures 1 to 5 , the loading station, the rotation center of the rotating arm 1, and the first processing station 2 are located on a first straight line, and the unloading station, the rotation center of the rotating arm 1, and the second processing station 3 are located on a second straight line;

[0119] The first clockwise direction is in the same direction as the second clockwise direction, the sixth clockwise direction, the seventh clockwise direction, and the eighth clockwise direction, and the first clockwise direction is in the opposite direction to the fourth clockwise direction;

[0120] The first angle is equal to the seventh angle, the second angle is equal to the fourth angle, the sixth angle, and the eighth angle, and the third angle and the fifth angle are equal to 180°.

[0121] In this embodiment, the first straight line and the second straight line are arranged to intersect each other to form a Figure 5The arrangement of each workstation shown in the figure is based on this arrangement. The first clockwise direction, the second clockwise direction, the sixth clockwise direction, the seventh clockwise direction, and the eighth clockwise direction are clockwise, the fourth clockwise direction is counterclockwise, and the third clockwise direction and the fifth clockwise direction can be clockwise or counterclockwise; the first angle and the seventh angle are 115°, the second angle, the fourth angle, the sixth angle, and the eighth angle are 65°, and the third angle and the fifth angle are 180°. Based on the rotation direction and rotation angle, taking the material picking end 101 as a material picking suction cup as an example, refer to Figure 5 , the above steps S21 to S53 are specifically as follows:

[0122] When the first laser completes laser processing of the battery cell 6 at the first processing station 2, the battery cell 6 at the first processing station 2 is sucked up by the material-picking suction cup; the rotating arm 1 rotates 115° clockwise, and then places the sucked battery cell 6 at the unloading station by the material-picking suction cup; the rotating arm 1 continues to rotate 65° clockwise, and then sucks up the battery cell 6 at the loading station by the material-picking suction cup; the rotating arm 1 continues to rotate 180° clockwise or counterclockwise, and then places the sucked battery cell 6 at the first processing station 2 by the material-picking suction cup; when the second laser completes laser processing of the battery cell 6 at the second processing station 3, the rotating arm 1 rotates 65° counterclockwise , and then the battery cell 6 of the second processing station 3 is sucked by the material picking suction cup; the rotating arm 1 continues to rotate 180° clockwise or counterclockwise, and then the sucked battery cell 6 is placed on the unloading station through the material picking suction cup; the rotating arm 1 continues to rotate 65° clockwise, and then the battery cell 6 of the loading station is sucked by the material picking suction cup; the rotating arm 1 continues to rotate 115° clockwise, and then the sucked battery cell 6 is placed on the second processing station 3 through the material picking suction cup; the rotating arm 1 continues to rotate 65° clockwise, so that the material picking suction cup reaches the first processing station 2 and subsequently sucks the processed battery cell 6; the subsequent steps are repeated in a cycle.

[0123] Based on the above settings, the rotating arm 1 has only three rotation angles (65°, 115°, 180°), which simplifies the number of rotation angles of the rotating arm 1 and avoids frequent switching of the rotation direction of the rotating arm 1, thereby simplifying the relevant preset programs for controlling the rotation of the rotating arm 1 and reducing the probability of errors in the rotation of the rotating arm 1, thereby ensuring that the laser processing operation and loading and unloading operations of the battery cell 6 can be carried out in an orderly manner according to the preset process, thereby improving the stability and reliability of the battery cell processing and production process.
