Based on the above scheme, the execution time periods of the laser processing operation, loading operation and unloading operation of the battery cell can be reasonably allocated, thereby reducing the time wasted in the laser processing process due to waiting for laser processing or waiting for loading and unloading, and also reducing the time wasted caused by performing loading and unloading operations separately, laying a structural foundation for speeding up the laser processing production rhythm of battery cells and improving the mass production efficiency of battery cells.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] 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.

[0063] 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 action of the first laser and the second laser, the coordination between the laser and the rotating arm, and the coordination between the first feeding end and the second feeding end, and can realize the loading operation of a part of the battery cells and the unloading operation of another part of the battery cells at the same time, 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 process due to waiting for laser processing or waiting for loading and unloading, and laying a structural foundation for accelerating the laser processing production rhythm of battery cells and improving the mass production efficiency of battery cells.

[0064] 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.

[0065] The rotating arm 1 has a first material-collecting end 101 and a second material-collecting end 102 which are arranged at intervals; the first material-collecting end 101 is used to transfer the battery cells 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 second material-collecting end 102 is used to transfer the battery cells 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;

[0066] The first laser is used to perform laser processing on the battery cell 6 transferred to the first processing station 2;

[0067] The second laser is used to perform laser processing on the battery cell 6 transferred to the second processing station 3;

[0068] The loading device 4 is used to transport the battery cells 6 to be processed to the loading station;

[0069] The unloading device 5 is used to transport the battery cells 6 processed in the unloading station to the outside.

[0070] In this embodiment, the rotating arm 1 can be configured as follows: Figure 3 In the L-shaped arm shown, the rotation center of the rotating arm 1 is located at the turning point of the L-shaped arm, the first feeding end 101 is arranged at one end of the L-shaped arm, and the second feeding end 102 is arranged at the other end of the L-shaped arm; the rotating arm 1 can also be set as a fan-shaped structure, the rotation center of the rotating arm 1 is located at the central angle of the fan, the first feeding end 101 and the second feeding end 102 are respectively arranged at the two inscribed angles of the fan (the angle enclosed by the radius of the fan and the arc); the rotating arm 1 can also be set as a T-shaped arm, the rotation center of the rotating arm 1 is located at the end of the vertical part of the T-shaped arm, the first feeding end 101 and the second feeding end 102 are respectively arranged at the two ends of the horizontal part of the T-shaped arm; in actual applications, the specific shape of the rotating arm 1 can be flexibly set according to needs, and they are not listed here one by one. A motor, a rotary cylinder or other driving device may be provided at the rotation center of the rotating arm 1 to drive the rotating arm 1 to rotate in a preset manner; the first picking end 101 and the second picking end 102 may adopt grabbing, clamping, sucking, hanging or other picking methods to fix and transfer the battery cell 6, and the above picking methods may be accomplished with the aid of grippers, pneumatic fingers, buckles, suction cups, magnets, hooks or other devices, which are not limited here.

[0071] 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.

[0072] 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 coordinated cooperation 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.

[0073] Furthermore, the rotating arm 1 is provided with a first material picking end 101 specifically for loading materials and a second material picking end 102 specifically for unloading materials. Through the coordination between the first material picking end 101 and the second material picking end 102, the loading operation of a part of the battery cells 6 and the unloading operation of another part of the battery cells 6 can be carried out simultaneously. Specifically, taking the rotating arm 1 passing through the first processing station 2, the second processing station 3, the loading station and the unloading operation once as a stroke, through the coordination between the first feeding end 101 and the second feeding end 102, the unloading operation of transferring the battery cell 6 processed in the first processing station 2 to the unloading station and the loading operation of transferring the battery cell 6 to be processed in the loading station to the first processing station 2 can be completed within one stroke, and the unloading operation of transferring the battery cell 6 processed in the second processing station 3 to the unloading station and the loading operation of transferring the battery cell 6 to be processed in the loading station to the second processing station 3 can be completed within one stroke; in this way, multiple returns of the rotating arm 1 caused by separate loading and unloading operations can be avoided, thereby greatly shortening the rotation distance of the rotating arm 1.

[0074] Based on the above arrangement, the execution time periods of the laser processing operation, loading operation and unloading operation of the battery cell 6 can be reasonably allocated, thereby reducing the time wasted in the laser processing process due to waiting for laser processing or waiting for loading and unloading, and also reducing the time wasted due to separate loading and unloading operations, thereby laying a structural foundation for speeding up the laser processing production rhythm of the battery cell 6 and improving the mass production efficiency of the battery cell 6.

[0075] 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.

[0076] Optionally, refer to Figures 1 to 3 The shortest straight-line distance between the loading station and the rotation center of the rotating arm 1 is equal to the shortest straight-line distance between the first feeding end 101 and the rotation center of the rotating arm 1, the shortest straight-line distance between the unloading station and the rotation center of the rotating arm 1 is equal to the shortest straight-line distance between the second feeding end 102 and the rotation center of the rotating arm 1, and the shortest straight-line distance between the loading station and the unloading station is equal to the shortest straight-line distance between the first feeding end 101 and the second feeding end 102.

[0077] In this embodiment, the lines connecting the loading station, the unloading station, and the rotation center of the rotating arm 1 form a triangle, and the lines connecting the first material picking end 101, the second material picking end 102, and the rotation center of the rotating arm 1 form another triangle, and the two triangles are congruent triangles. Based on this relative position relationship, referring to the specific loading and unloading process described in the previous embodiment, when the first material picking end 101 arrives at the loading station with the rotation of the rotating arm 1, the second material picking end 102 also arrives at the unloading station at the same time with the rotation of the rotating arm 1. In this way, the material picking operation of the first material picking end 101 (picking up the battery cell 6 to be processed in the loading station) and the material placing operation of the second material picking end 102 (placing the processed battery cell 6 carried in the unloading station) can be performed simultaneously without a sequence, thereby further compressing the time of loading and unloading operations, speeding up the laser processing production rhythm, and thereby further improving the mass production efficiency of the battery cell 6.

[0078] Optionally, refer to Figures 1 to 3 The rotating arm 1 is L-shaped, and the turning part of the rotating arm 1 rotates around the first axis (not shown in the figure) under the drive of the first driving assembly 7. The first material taking end 101 is arranged at the first end of the rotating arm 1, and the second material taking end 102 is arranged at the second end of the rotating arm 1;

[0079] The cell laser processing system further includes a first swing arm 8, the middle portion of which is rotatably connected to the first end of the rotating arm 1 around a second axis (not shown in the figure); the first material taking end 101 includes at least two first material taking parts 1011, which are distributed at both ends of the first swing arm 8, and each first material taking part 1011 is used to transfer at least one cell 6;

[0080] And / or, the battery cell laser processing system also includes a second swing arm 9, the middle part of the second swing arm 9 is rotatably connected to the second end of the rotating arm 1 around a third axis (not shown in the figure); the second material picking end 102 includes at least two second material picking parts 1021, at least two second material picking parts 1021 are distributed at both ends of the second swing arm 9, and each second material picking part 1021 is used to transfer at least one battery cell 6.

[0081] 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 first swing arm 8 may be rotatably connected to the first end of the rotating arm 1 by means of a seat bearing; wherein, the rotation angle of the first swing arm 8 relative to the rotating arm 1 may be adjusted manually, and after the first swing arm 8 is rotated into place, the first swing arm 8 may be fixed at the current angular position by fastening devices such as screws, buckles, spring plungers, etc., or the first swing arm 8 may be driven to rotate by a drive device such as a motor and a cylinder, and the first 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 first swing arm 8 relative to the rotating arm 1, the position adjustment of the first material picking end 101 relative to the rotating arm 1 is realized, so that the first material picking end 101 can reach the corresponding workstation more accurately with the rotation of the rotating arm 1.

[0082] The first material picking part 1011 can be understood as the part on the first material picking end 101 that is directly used for picking and placing materials on the battery cell 6. When the first material picking end 101 includes at least two first material picking parts 1011, at least two battery cells 6 in the corresponding workstations can be picked and placed 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 first material picking parts 1011 as two as an example, one of the first material picking parts 1011 can be set at one end of the first swing arm 8, and the other first material picking part 1011 can be set at the other end of the first swing arm 8.

[0083] Similarly, the second swing arm 9 can be rotatably connected to the second end of the rotating arm 1 by means of a seat bearing; wherein, the rotation angle of the second swing arm 9 relative to the rotating arm 1 can be adjusted manually, and after the second swing arm 9 is rotated into place, the second swing arm 9 can be fixed at the current angular position by means of fastening devices such as screws, buckles, spring plungers, etc., or the second swing arm 9 can be driven to rotate by a driving device such as a motor or a cylinder, and the second swing arm 9 rotated into place can be fixed at the current angular position based on the self-locking property of the driving device, which is not limited here. By rotating the second swing arm 9 relative to the rotating arm 1, the position adjustment of the second material picking end 102 relative to the rotating arm 1 is realized, so that the second material picking end 102 can reach the corresponding workstation more accurately with the rotation of the rotating arm 1.

[0084] The second material picking part 1021 can be understood as the part on the second material picking end 102 that is directly used for picking and placing materials on the battery cell 6. When the second material picking end 102 includes at least two second material picking parts 1021, at least two battery cells 6 in the corresponding workstations can be picked and placed 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 second material picking parts 1021 as two as an example, one of the second material picking parts 1021 can be set at one end of the second swing arm 9, and the other second material picking part 1021 can be set at the other end of the second swing arm 9.

[0085] Corresponding to the above-mentioned arrangement, each workstation should be provided with at least two accommodating areas for accommodating battery cells 6, 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.

[0086] On the basis of the above embodiment, since at least two first material-grabbing 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 first material-grabbing parts 1011 relative to the rotating arm 1 remain unchanged, that is, the angle of the first swing arm 8 relative to the rotating arm 1 remains unchanged, then the absolute angles of the at least two first material-grabbing 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 first material-grabbing part 1011 at each end of the first swing arm 8, Figure 2 In the top-down perspective shown, if the extension direction of the first swing arm 8 in the initial state is the left-right direction, then the two first material picking parts 1011 are arranged at intervals along the left-right direction in the initial state; when the rotating arm 1 rotates a certain angle, if the angle of the first swing arm 8 relative to the rotating arm 1 remains unchanged, then the extension direction of the first swing arm 8 will change to extend obliquely upward or obliquely downward with the rotation of the rotating arm 1, and at this time, the two first material picking parts 1011 will become arranged at intervals along the oblique upward or oblique 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 oblique upward or oblique downward direction on the two first material picking parts 1011 obviously cannot be placed one-to-one in the two accommodating areas of the corresponding workstation.

[0087] In order to solve the above problems, the following embodiments are proposed:

[0088] Reference Figures 1 to 3 , also includes a second drive assembly 10; while the first drive assembly 7 drives the rotating arm 1 to rotate around the first axis, the second drive assembly 10 is used to drive the first swing arm 8 to rotate around the second axis relative to the rotating arm 1; the first axis is parallel to the second axis.

[0089] 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 first material picking end 101 reach each corresponding station along the circumferential direction through a simple rotation action, thereby simplifying the structure of the laser processing system.

[0090] In this embodiment, by setting up the second driving component 10, the first swing arm 8 can be driven to rotate around the second axis in real time during the process of the rotating arm 1 rotating around the first axis, so as to realize the real-time adjustment of the angle of the first swing arm 8 relative to the rotating arm 1, so that the absolute angle of at least two first material picking parts 1011 in the laser processing system will not be affected 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 first material picking parts 1011 can rotate with the first 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 first swing arm 8 can be accurately placed in the corresponding accommodating areas.

[0091] Similarly, based on the above embodiment, since at least two second material-collecting parts 1021 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 second material-collecting parts 1021 relative to the rotating arm 1 remain unchanged, that is, the angle of the second swing arm 9 relative to the rotating arm 1 remains unchanged, then the absolute angles of the at least two second material-collecting parts 1021 in the laser processing system will continue to change with the rotation of the rotating arm 1. Specifically, taking the example of providing a second material-collecting part 1021 at each end of the second swing arm 9, Figure 2 In the top-down perspective shown, if the extension direction of the second swing arm 9 in the initial state is the left-right direction, then the two second material picking parts 1021 are arranged at intervals along the left-right direction in the initial state; when the rotating arm 1 rotates a certain angle, if the angle of the second swing arm 9 relative to the rotating arm 1 remains unchanged, then the extension direction of the second swing arm 9 will change to extend obliquely upward or obliquely downward with the rotation of the rotating arm 1, and at this time, the two second material picking parts 1021 will become arranged at intervals along the oblique upward or oblique 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 oblique upward or oblique downward direction on the two second material picking parts 1021 obviously cannot be placed one-to-one in the two accommodating areas of the corresponding workstation.

[0092] In order to solve the above problems, the following embodiments are proposed:

[0093] Reference Figures 1 to 3 , also includes a third drive assembly 11; while the first drive assembly 7 drives the rotating arm 1 to rotate around the first axis, the third drive assembly 11 is used to drive the second swing arm 9 to rotate around the third axis relative to the rotating arm 1; the first axis is parallel to the third axis.

[0094] Diagrammatically, the first axis and the third 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 second material picking end 102 reach each corresponding station along the circumferential direction through a simple rotation action, thereby simplifying the structure of the laser processing system.

[0095] In this embodiment, by setting up the third driving component 11, the second swing arm 9 can be driven to rotate around the third axis in real time during the process of the rotating arm 1 rotating around the first axis, so as to realize the real-time adjustment of the angle of the second swing arm 9 relative to the rotating arm 1, so that the absolute angle of at least two second material picking parts 1021 in the laser processing system will not be affected 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 second material picking parts 1021 can rotate with the second swing arm 9 to a position opposite to at least two accommodating areas in the corresponding workstation, so that at least two battery cells 6 on the second swing arm 9 can be accurately placed in the corresponding accommodating areas.

[0096] Based on the above two embodiments, the first swing arm 8 and the second swing arm 9 can adjust the angle in real time during the rotation of the rotating arm 1, and the arrangement direction of each accommodating area in each station can be uniformly set, for example, Figure 2 As shown, they are all arranged along the left-right direction, without the need for differentiated adjustments according to different rotation angles of the rotating arm 1, thus improving the applicability of the laser processing system.

[0097] Among them, the second drive assembly 10 and the third drive assembly 11 can both include drive devices such as motors and cylinders, as well as matching reduction mechanisms and transmission mechanisms. The first drive assembly 7, the second drive assembly 10, and the third drive assembly 11 can be electrically connected to the same main control module, so that the parameters such as the rotation angle, rotation node, and rotation speed of the first drive assembly 7, the second drive assembly 10, and the third drive assembly 11 can be uniformly regulated through the 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 10 and the third drive assembly 11. Preferably, the action of the second drive assembly 10 driving the first 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, and the action of the third drive assembly 11 driving the second swing arm 9 to rotate should also 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 first swing arm 8 and the second swing arm 9 to rotate in place after the rotating arm 1 rotates into place, thereby further improving the laser processing production efficiency of the battery cell 6.

[0098] Optionally, refer to Figures 1 to 3The 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 .

[0099] Optionally, refer to Figures 1 to 3 The second driving assembly 10 includes a second motor 1001 and a second reduction gear 1002 ; the driving end of the second motor 1001 is connected to the input end of the second reduction gear 1002 , and the output end of the second reduction gear 1002 is connected to the middle part of the first swing arm 8 .

[0100] Optionally, refer to Figures 1 to 3 The third driving assembly 11 includes a third motor 1101 and a third reduction gear 1102 ; the driving end of the third motor 1101 is connected to the input end of the third reduction gear 1102 , and the output end of the third reduction gear 1102 is connected to the middle part of the second swing arm 9 .

[0101] Specifically, by providing the first reduction gear 702, the second reduction gear 1002 and the third reduction gear 1102, the rotation speed of the first motor 701, the second motor 1001 and the third motor 1101 can be reduced and the torque can be increased, so that the rotating arm 1, the first swing arm 8 and the second swing arm 9 can stably rotate in a preset manner under load. Figure 3 As shown, the third motor 1101 and the third reduction device 1102 can also be directly installed on the rotating arm 1 for setting one end of the first swing arm 8, without the need to install the second motor 1001 at the rotation center of the rotating arm 1 and transmit the power through a transmission member such as a belt. Figure 3 As shown, the second swing arm 9 is directly mounted on the rotating arm 1, and there is no need to install the third motor 1101 at the rotation center of the rotating arm 1 and transmit the power through a transmission member such as a belt; thus, the driving accuracy and stability are improved by direct drive. Correspondingly, the second reduction gear 1002 and the third reduction gear 1102 can be set as planetary reducers, which have the advantages of light weight, small size, large transmission ratio range, and smooth transmission. It can avoid that it occupies too much space on the rotating arm 1 and interferes with other devices during the rotation process, and can also avoid the problem of difficulty in rotating the rotating arm 1 due to its excessive weight.

[0102] Optionally, refer to Figure 1 and Figure 2 , and also includes a fourth drive component 12, 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 fourth drive component 12 is used to move the battery cell 6 processed in the processing area of ​​the first laser to the first processing station 2.

[0103] 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 fourth drive assembly 12, 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 fourth drive assembly 12 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.

[0104] Optionally, refer to Figure 1 and Figure 2 , and also includes a fifth driving component 13, 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 fifth driving component 13 is used to move the battery cell 6 processed in the processing area of ​​the second laser to the second processing station 3.

[0105] 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 fifth drive assembly 13, 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 mutual 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 fifth drive assembly 13 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.

[0106] Optionally, refer to Figure 1 and Figure 2, also includes a first support frame 14, the middle part of the first support frame 14 is connected to the fourth drive assembly 12; 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 14, and the second sub-station 202 is arranged on the other side of the first support frame 14, and the first sub-station 201 and the second sub-station 202 are used to place the battery cell 6; the fourth drive assembly 12 is used to drive the first support frame 14 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 taking and placing area of ​​the rotating arm 1.

[0107] Specifically, Figure 1 and Figure 2 As shown, the fourth drive assembly 12 can drive the first support frame 14 to rotate to ensure that when the first sub-station 201 rotates with the first support frame 14 to the processing area of ​​the first laser, the second sub-station 202 can simultaneously rotate with the first support frame 14 to the material picking and placing area of ​​the rotating arm 1 at the first processing station 2 (specifically, the material picking and placing area of ​​the first material picking end 101 and the second material picking end 102 at the first processing station 2); and to ensure that when the second sub-station 202 rotates with the first support frame 14 to the processing area of ​​the first laser, the first sub-station 201 can simultaneously rotate with the first support frame 14 to the material picking and placing area of ​​the rotating arm 1 at the first processing station 2 (specifically, the material picking and placing area of ​​the first material picking end 101 and the second material picking end 102 at the first processing station 2).

[0108] Based on the above arrangement, when the first sub-station 201 is located in the material picking and placing area of ​​the rotating arm 1 and the second sub-station 202 is located in the processing area of ​​the first laser, the first sub-station 201 has a processed battery cell 6 placed therein, and the first laser is laser processing the battery cell 6 in the second sub-station 202. At this time, the second material picking end 102 can take away the processed battery cell 6 in the first sub-station 201 and perform a material unloading operation, and then the first material picking end 101 can place another battery cell 6 to be processed in the first sub-station 201, and then the first material picking end 101 and the second material picking end 102 can move to other stations with the rotation of the rotating arm 1 to perform corresponding operations; when the battery cell 6 in the second sub-station 202 is processed, the fourth drive assembly 12 drives the first support frame 14 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 second sub-station When the first sub-station 201 is in the process of being processed, the first laser can be used to perform laser processing on the battery cell 6 in the first sub-station 201; when the first material picking end 101 and the second material picking end 102 arrive at the first processing station 2 again, the second material picking end 102 can take away the battery cell 6 processed in the second sub-station 202 and perform unloading operations, and then the first material picking end 101 can place another battery cell 6 to be processed in the second sub-station 202, and then the first material picking end 101 and the second material picking end 102 can be moved to other stations for corresponding operations as the rotating arm 1 rotates; when the battery cell 6 in the first sub-station 201 is processed, the fourth driving component 12 drives the first support frame 14 to rotate again to drive the second sub-station 202 to enter the processing area of ​​the first laser, and at the same time drive the first sub-station 201 to enter the material picking area of ​​the rotating arm 1, and so on.

[0109] Through the above operations, when the laser processing operation of the first laser takes a long time, 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 operations of the battery cell 6 can be more reasonably allocated, thereby further improving the batch production efficiency of the battery cell 6.

[0110] Optionally, refer to Figure 1 and Figure 2, and also includes a second support frame 15, the middle part of the second support frame 15 is connected to the fifth driving assembly 13; 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 15, and the fourth sub-station 302 is arranged on the other side of the second support frame 15, and the third sub-station 301 and the fourth sub-station 302 are used to place the battery cell 6; the fifth driving assembly 13 is used to drive the second support frame 15 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 taking and placing area of ​​the rotating arm 1.

[0111] Specifically, Figure 1 and Figure 2 As shown, the fifth driving assembly 13 can drive the second support frame 15 to rotate to ensure that when the third sub-station 301 rotates with the second support frame 15 to the processing area of ​​the second laser, the fourth sub-station 302 can simultaneously rotate with the second support frame 15 to the material picking and placing area of ​​the rotating arm 1 at the second processing station 3 (specifically, the material picking and placing area of ​​the first material picking end 101 and the second material picking end 102 at the second processing station 3); and to ensure that when the fourth sub-station 302 rotates with the second support frame 15 to the processing area of ​​the second laser, the third sub-station 301 can simultaneously rotate with the second support frame 15 to the material picking and placing area of ​​the rotating arm 1 at the second processing station 3 (specifically, the material picking and placing area of ​​the first material picking end 101 and the second material picking end 102 at the second processing station 3).

[0112] Based on the above arrangement, when the third sub-station 301 is located in the material picking and placing area of ​​the rotating arm 1 and the fourth sub-station 302 is located in the processing area of ​​the second laser, the third sub-station 301 contains processed battery cells 6, and the second laser is laser processing the battery cells 6 in the fourth sub-station 302. At this time, the second material picking end 102 can take away the processed battery cells 6 in the third sub-station 301 and perform unloading operations, and then the first material picking end 101 can place another battery cell 6 to be processed in the third sub-station 301, and then the first material picking end 101 and the second material picking end 102 can move to other stations with the rotation of the rotating arm 1 to perform corresponding operations; when the battery cells 6 in the fourth sub-station 302 are processed, the fifth driving assembly 13 drives the second supporting frame 15 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 fourth sub-station When the first material picking end 101 and the second material picking end 102 arrive at the second processing station 3 again, the second material picking end 102 can take away the processed battery cell 6 in the fourth sub-station 302 and perform unloading operation, and then the first material picking end 101 can place another battery cell 6 to be processed in the fourth sub-station 302, and then the first material picking end 101 and the second material picking end 102 can move to other stations with the rotation of the rotating arm 1 to perform corresponding operations; when the battery cell 6 in the third sub-station 301 is processed, the fifth driving component 13 drives the second support frame 15 to rotate again to drive the fourth sub-station 302 to enter the processing area of ​​the second laser, and at the same time drive the third sub-station 301 to enter the picking and placing area of ​​the rotating arm 1, and so on.

[0113] Through the above operations, when the laser processing operation of the second laser takes a long time, 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 operations of the battery cell 6 can be more reasonably allocated, thereby further improving the batch production efficiency of the battery cell 6.

[0114] Optionally, refer to Figures 1 to 3, the first material picking end 101 and / or the second material picking end 102 are configured as a material picking suction cup; more specifically, when the first material picking end 101 includes at least two first material picking parts 1011, each first material picking part 1011 is a material picking suction cup; similarly, when the second material picking end 102 includes at least two second material picking parts 1021, each second material picking part 1021 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, and 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 to the greatest extent. Preferably, the material removal suction cup can be a Bernoulli suction cup, which can transfer the battery cell 6 without directly contacting the surface of the battery cell 6, thereby reducing physical damage and contamination 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 removal and transfer operations.

[0115] 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:

[0116] S1, the rotating arm 1 rotates along the first preset path to retrieve the battery cell 6 to be processed in the loading station through the first retrieving end 101, and transfers the processed battery cell 6 carried by the second retrieving end 102 to the unloading station;

[0117] S2, the rotating arm 1 rotates along the second preset path to retrieve the battery cell 6 processed in the second processing station 3 through the second material-retrieving end 102, and transfers the battery cell 6 to be processed carried by the first material-retrieving end 101 to the second processing station 3;

[0118] S3, the rotating arm 1 rotates along the third preset path to retrieve the battery cell 6 to be processed in the loading station through the first retrieving end 101, and transfers the processed battery cell 6 carried by the second retrieving end 102 to the unloading station;

[0119] S4, the rotating arm 1 rotates along the fourth preset path to retrieve the battery cell 6 processed in the first processing station 2 through the second retrieving end 102, and transfers the battery cell 6 to be processed carried by the first retrieving end 101 to the first processing station 2;

[0120] S5, repeat the above steps S1 to S4.

[0121] In this embodiment, the first preset path, the second preset path, the third preset path, and the fourth preset path may all include one or more rotation trajectories. For example, the arm 1 rotates along the first preset path, which may be the arm 1 rotating forwardly or reversely at a certain angle, or the arm 1 rotating forwardly at a certain angle and then rotating forwardly or reversely at a certain angle, or the arm 1 rotating reversely at a certain angle and then rotating forwardly or reversely at a certain angle; the arm 1 rotating along other preset paths is similar. In actual operation, it only needs 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.

[0122] It should be noted that the starting node of step S1 in this embodiment is the stage where the second material feeding end 102 already carries the processed battery cells 6, the first laser is already performing laser processing on the battery cells 6 of the first processing station 2, and the second laser is already performing laser processing on the battery cells 6 of the second processing station 3, and the battery cells 6 of the second processing station 3 will be processed before the battery cells 6 of the first processing station 2. That is, step S1 can be understood as the intermediate stage after the battery cell processing procedure has started to be executed in a cycle, rather than the initial stage when there are no battery cells 6 in the first processing station 2, the second processing station 3, the first material feeding end 101 and the second material feeding end 102.

[0123] 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 first material picking end 101 can drive the battery cell 6 to be loaded and transferred in an orderly manner between the first processing station 2, the second processing station 3, and the loading station, and the second material picking end 102 can drive the battery cell 6 to be unloaded and transferred in an orderly manner between the first processing station 2, the second processing station 3, and the unloading station. Based on this structural setting, the first laser and the second laser can be configured to perform laser processing on the battery cell 6 transferred to the corresponding processing station in an alternating manner; 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 to transfer the battery cell 6 to be processed in the loading station to the second processing station 3, or perform an unloading operation to transfer the battery cell 6 processed in the second processing station 3 to the unloading station; similarly, when the second laser is When laser processing is performed on the battery cell 6 at the second processing station 3, the first 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 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 achieved at the same time. Furthermore, through the coordination between the first material picking end 101 and the second material picking end 102, the loading operation of a part of the battery cells 6 and the unloading operation of another part of the battery cells 6 can be carried out simultaneously; specifically, the rotating arm 1 passes through the first processing station 2, the second processing station 3, the loading station, and the unloading operation once as a stroke, and through the coordination between the first material picking end 101 and the second material picking end 102, the unloading operation of transferring the battery cells 6 processed in the first processing station 2 to the unloading station and the loading operation of transferring the battery cells 6 to be processed in the loading station to the first processing station 2 can be completed within one stroke, and the unloading operation of transferring the battery cells 6 processed in the second processing station 3 to the unloading station and the loading operation of transferring the battery cells 6 to be processed in the loading station to the second processing station 3 can be completed within one stroke; in this way, multiple returns of the rotating arm 1 caused by separate loading and unloading operations can be avoided, thereby greatly shortening the rotation distance of the rotating arm 1.Based on the above scheme, the execution time periods of the laser processing operation, loading operation and unloading operation of the battery cell 6 can be reasonably allocated, thereby reducing the time wasted in the laser processing process due to waiting for laser processing or waiting for loading and unloading, and also reducing the time wasted due to separate loading and unloading operations. In this way, the laser processing production rhythm of the battery cell 6 is accelerated and the batch production efficiency of the battery cell 6 is improved.

[0124] 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 around the rotating arm 1 at intervals, and the relative distance between the loading station, the unloading station, and the rotation center of the rotating arm 1 is equal to the relative distance between the first material retrieving end 101, the second material retrieving end 102, and the rotation center of the rotating arm 1; steps S1 to S4 include:

[0125] S11, the rotating arm 1 rotates in a first clockwise direction by a first angle, and then the first material taking end 101 takes the battery cell 6 to be processed in the loading station, and at the same time places the processed battery cell 6 carried by the second material taking end 102 in the unloading station;

[0126] S21, the rotating arm 1 rotates in a second clockwise direction by a second angle, and then the second material taking end 102 takes the battery cell 6 processed in the second processing station 3;

[0127] S22, the rotating arm 1 rotates in a third clockwise direction by a third angle, and then places the battery cell 6 to be processed carried by the first material taking end 101 on the second processing station 3;

[0128] S31, the rotating arm 1 rotates in a fourth clockwise direction by a fourth angle, and then the first material taking end 101 takes the battery cell 6 to be processed in the loading station, and at the same time places the processed battery cell 6 carried by the second material taking end 102 in the unloading station;

[0129] S41, the rotating arm 1 rotates in a fifth clockwise direction by a fifth angle, and then the second material taking end 102 takes the battery cell 6 processed in the first processing station 2;

[0130] S42, the rotating arm 1 rotates in a sixth clockwise direction by a sixth angle, and then places the battery cell 6 to be processed carried by the first material taking end 101 on the first processing station 2.

[0131] 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 make the first material picking end 101 and the second material picking end 102 reach each station through a single rotation action, thereby simplifying the structure of the laser processing system.

[0132] Based on the relative position relationship between each workstation and the two material picking ends in this embodiment, when the first material picking end 101 reaches the loading station with the rotation of the rotating arm 1, the second material picking end 102 can also reach the unloading station at the same time with the rotation of the rotating arm 1. In this way, the material picking operation of the first material picking end 101 (picking up the battery cells 6 to be processed in the loading station) and the material placing operation of the second material picking end 102 (placing the processed battery cells 6 carried at the unloading station) can be performed simultaneously without any order of precedence, thereby further compressing the time of loading and unloading operations, speeding up the laser processing production rhythm, and thereby further improving the mass production efficiency of the battery cells 6.

[0133] 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 above steps S11 to S42 are specifically as follows:

[0134] The second material retrieving end 102 carries the processed battery cell 6, the first laser is laser processing the battery cell 6 of the first processing station 2, and the second laser is laser processing the battery cell 6 of the second processing station 3, and the battery cell 6 of the second processing station 3 will be processed before the battery cell 6 of the first processing station 2; after the above steps S11 to S42 start, the rotating arm 1 rotates counterclockwise by a first angle, so that the first material retrieving end 101 reaches the loading station, and the second material retrieving end 102 also At the same time, the first material picking end 101 picks up the battery cell 6 to be processed in the loading station, and the processed battery cell 6 carried by the second material picking end 102 is placed in the unloading station; the rotating arm 1 continues to rotate counterclockwise by a second angle, so that the second material picking end 102 reaches the second processing station 3, and then the second material picking end 102 picks up the battery cell 6 processed in the second processing station 3; the rotating arm 1 continues to rotate counterclockwise by a third angle , the first material taking end 101 reaches the second processing station 3, and then the battery cell 6 to be processed carried by the first material taking end 101 is placed on the second processing station 3; the rotating arm 1 continues to rotate counterclockwise by a fourth angle, so that the first material taking end 101 reaches the loading station, and the second material taking end 102 also reaches the unloading station at the same time, and then the first material taking end 101 performs a material taking operation on the battery cell 6 to be processed in the loading station, and at the same time, the processed battery cell 6 carried by the second material taking end 102 is placed on Unloading station; the rotating arm 1 continues to rotate counterclockwise at a fifth angle, so that the second material picking end 102 reaches the first processing station 2, and then the second material picking end 102 is used to pick up the battery cell 6 processed in the first processing station 2; the rotating arm 1 continues to rotate counterclockwise at a sixth angle, so that the first material picking end 101 reaches the first processing station 2, and then the battery cell 6 to be processed carried by the first material picking end 101 is placed in the first processing station 2; the above steps are then repeated.

[0135] 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.

[0136] 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;

[0137] The third clockwise direction is the same as the fourth clockwise direction, the fifth clockwise direction, and the sixth clockwise direction;

[0138] The third angle is equal to the sixth angle, the fourth angle is equal to the fifth angle, and the first angle and the second angle are equal to 180°.

[0139] In this embodiment, the first straight line and the second straight line are arranged to intersect each other to form a Figure 5 The arrangement of the various workstations shown in the figure is based on this arrangement, the third clockwise direction, the fourth clockwise direction, the fifth clockwise direction, and the sixth clockwise direction are all counterclockwise, and the first clockwise direction and the second clockwise direction can be clockwise or counterclockwise; preferably, the first clockwise direction and the second clockwise direction are counterclockwise, so that the rotating arm 1 can always rotate in the same direction. The third angle and the sixth angle are 65°, and the fourth angle and the fifth angle are 115°.

[0140] Based on the rotation direction and rotation angle, refer to Figure 5 , the above steps S11 to S42 are specifically as follows:

[0141] The second material retrieving end 102 carries the processed battery cell 6, the first laser is laser processing the battery cell 6 of the first processing station 2, and the second laser is laser processing the battery cell 6 of the second processing station 3, and the battery cell 6 of the second processing station 3 will be processed before the battery cell 6 of the first processing station 2; after the above steps S11 to S42 start, the rotating arm 1 rotates 180° in the counterclockwise direction, so that the first material retrieving end 101 reaches the loading station, and the second material retrieving end 102 At the same time, it reaches the unloading station, and then the first material picking end 101 is used to pick up the battery cell 6 to be processed in the loading station, and at the same time, the processed battery cell 6 carried by the second material picking end 102 is placed in the unloading station; the rotating arm 1 continues to rotate 180° counterclockwise, so that the second material picking end 102 reaches the second processing station 3, and then the second material picking end 102 is used to pick up the battery cell 6 processed in the second processing station 3; the rotating arm 1 continues to rotate 65° counterclockwise , the first material taking end 101 reaches the second processing station 3, and then the battery cell 6 to be processed carried by the first material taking end 101 is placed on the second processing station 3; the rotating arm 1 continues to rotate 115° counterclockwise, so that the first material taking end 101 reaches the loading station, and the second material taking end 102 also reaches the unloading station at the same time, and then the first material taking end 101 performs a material taking operation on the battery cell 6 to be processed in the loading station, and at the same time, the processed battery cell 6 carried by the second material taking end 102 is placed on Unloading station; the rotating arm 1 continues to rotate 115° in the counterclockwise direction, so that the second material picking end 102 reaches the first processing station 2, and then the second material picking end 102 is used to pick up the battery cell 6 processed in the first processing station 2; the rotating arm 1 continues to rotate 65° in the counterclockwise direction, so that the first material picking end 101 reaches the first processing station 2, and then the battery cell 6 to be processed carried by the first material picking end 101 is placed in the first processing station 2; the subsequent steps are repeated in a cycle.

[0142] Based on the above settings, the rotating arm 1 has only three rotation angles (65°, 115°, 180°), thereby simplifying the number of rotation angles of the rotating arm 1 and eliminating the need to switch the rotation direction of the rotating arm 1. This simplifies the relevant preset programs for controlling the rotation of the rotating arm 1 and reduces the probability of errors in the rotation of the rotating arm 1, thereby ensuring that the laser processing operations 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.
