[0003] In the battery production process, A battery cells and B battery cells are produced by two different devices respectively, so A battery cells and B battery cells need to be transported to the next ultrasonic tab welding process through different incoming material logistics lines. Before the ultrasonic tab welding process, A battery cells and B battery cells need to be paired into a battery cell group first, so that the copper tabs and aluminum tabs of A battery cells and B battery cells are opposite to each other, to facilitate the next ultrasonic tab welding process.

[0005] In the process of pairing battery cells, A battery cells and B battery cells are usually paired by a single robot. Specifically, the single robot can only grab one A battery cell or one B battery cell at a time, and after grabbing A battery cells and B battery cells by the single robot, the single robot places A battery cells and B battery cells into empty trays on the material removal logistics line for pairing. After pairing is completed, the material removal logistics line is used to transport the battery cell group to the next process.

[0076] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative work are within the scope of protection of the present application.

[0077] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0078] In addition, in addition to indicating the orientation or positional relationship, the above-mentioned part of the terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain dependent relationship or connection relationship in some cases. Those of ordinary skill in the art can understand the specific meaning of these terms in the present application according to the specific situation.

[0079] In addition, the terms "mount", "set", "provided with", "connect", "connected" should be broadly understood. For example, it can be fixed connection, detachable connection, or integral structure; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0080] In addition, the terms "first", "second" and the like are mainly used to distinguish different devices, elements or components (the specific type and structure may be the same or different), and are not intended to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0081] As described in the background of the application, in the related art, the electric core is the core part of the battery, and according to the current process technology, the battery of the mainstream industry is usually composed of A electric core (i.e. first electric core in the application) and B electric core (i.e. second electric core in the application).

[0082] In the battery production process, A and B electric cores are produced by two different devices respectively, so A and B electric cores need to be transported to the next ultrasonic tab welding process through different incoming material logistics lines. Before the ultrasonic tab welding process, A and B electric cores need to be paired into an electric core group first, so that the copper tabs and aluminum tabs of A and B electric cores are opposite to each other, to facilitate the next ultrasonic tab welding process.

[0083] In the related art, in addition to using two different incoming material logistics lines to transport A and B electric cores, a outgoing material logistics line is also used, which is used to provide empty trays for placing electric core groups and to transport electric core groups to the next process.

[0084] In the process of pairing electric cores, A and B electric cores are usually paired by a single mechanical hand. Specifically, the single mechanical hand can only grab one A electric core or one B electric core at a time, and after grabbing A and B electric cores by the single mechanical hand respectively, A and B electric cores are placed into the empty tray on the outgoing material logistics line for pairing. After pairing is completed, the electric core group is transported to the next process through the outgoing material logistics line.

[0085] However, the problem is that when pairing electric cores by the above-mentioned method, the pairing efficiency of electric cores is low, which in turn also makes the production efficiency of the battery low, and cannot meet the high-efficiency battery production demand of customers.

[0086] Embodiment one

[0087] In view of the above problems, the application provides an electric core pairing system to solve the problem of low electric core pairing efficiency in the related art.

[0088] The technical solutions of the application will be further described below with reference to specific embodiments and drawings:

[0089] As shown in Figure 1 , Figure 2 and Figure 3 , the electric core pairing system comprises a rack 1, a moving module 2, a rotating assembly 3 and a picking assembly 4. The moving module 2 is arranged on the rack 1, the rotating assembly 3 is arranged on the moving module 2, and the rotating assembly 3 has a rotating shaft (not shown in the figure). The picking assembly 4 is arranged on the rotating assembly 3, and the picking assembly 4 comprises a first picking piece 41 and a second picking piece 42, and the first picking piece 41 and the second picking piece 42 are arranged symmetrically about the center of the rotating shaft.

[0090] The moving module 2 is used to drive the first picking piece 41 and the second picking piece 42 to move to the first electric core 5 and the second electric core 6 respectively to pick up the first electric core 5 and the second electric core 6 respectively (as shown in Figure 8 ), the rotating assembly 3 is used to drive the first picking piece 41 and the second picking piece 42 to rotate around the rotating shaft to exchange the positions of the first electric core 5 and the second electric core 6, and the first electric core 5 and the second electric core 6 are electric cores that can be paired with each other.

[0091] When the electric core pairing system is used for electric core pairing, the first electric core 5 can comprise a first group of first electric cores 51 and a second group of first electric cores 52 (as shown in Figure 8 ), and the second electric core 6 can comprise a first group of second electric cores 61 and a second group of second electric cores 62 (as shown in Figure 8 ), that is, the first electric core 5 can be the first group of first electric cores 51 or the second group of first electric cores 52, and the second electric core 6 can be the first group of second electric cores 61 or the second group of second electric cores 62. Since the first picking piece 41 and the second picking piece 42 can pick up the first electric core 5 and the second electric core 6 respectively, the first picking piece 41 and the second picking piece 42 can also pick up the first group of first electric cores 51 and the first group of second electric cores 61 respectively during pairing. Of course, the first picking piece 41 and the second picking piece 42 can also pick up the second group of first electric cores 52 and the second group of second electric cores 62 respectively. The present embodiment takes the first picking piece 41 and the second picking piece 42 being able to pick up the first group of first electric cores 51 and the first group of second electric cores 61 respectively as an example for description.

[0092] During the pairing process, firstly, the moving module 2 drives the first pickup member 41 and the second pickup member 42 to move to the first battery cell 5 and the second battery cell 6 respectively to pick up the first group of first battery cell 51 and the first group of second battery cell 61 respectively. Then, the rotating component 3 drives the first pickup member 41 and the second pickup member 42 to rotate around the rotating axis so that the positions of the first group of first battery cell 51 and the first group of second battery cell 61 are interchanged. After the position interchange, the first group of first battery cell 51 and the second group of second battery cell 62 can be paired, and the first group of second battery cell 61 and the second group of first battery cell 52 can be paired, that is, they can both be paired to form a battery cell group composed of the first battery cell 5 and the second battery cell 6.

[0093] Since the first pickup member 41 and the second pickup member 42 can pick up the first battery cell 5 and the second battery cell 6 respectively during a pairing process, at least two battery cell groups composed of the first battery cell 5 and the second battery cell 6 can be paired in one pairing process through the joint picking of the first pickup member 41 and the second pickup member 42. Compared with the related technology, which can only pair one battery cell group in one pairing process, this application is conducive to improving the pairing efficiency of battery cells, and thus also improving the production efficiency of batteries, which is conducive to meeting the customers' demand for high-efficiency battery production.

[0094] The first pickup 41 and the second pickup 42 are arranged symmetrically about the axis of rotation, specifically, as follows: Figure 4 and Figure 5 As shown, the first pickup 41 and the second pickup 42 are in the first direction ( Figure 5 They are positioned on either side of the rotation axis (not shown in the figure) along the X-axis direction, and in the second direction ( Figure 5 The cells are also positioned on opposite sides of the rotation axis (in the Y-axis direction). This arrangement ensures that after the first cell 5 and the second cell 6 are swapped positions by the rotating component 3, each first cell 5 in each paired cell group can be located on the same side of each second cell 6. This guarantees the consistency of each paired cell group, eliminating the need for further adjustments before proceeding to the next process and thus improving battery production efficiency.

[0095] like Figure 6 As shown, the rotating assembly 3 includes a rotating motor 31 and a reducer 32. The rotating motor 31 is disposed on the moving module 2. The output shaft of the rotating motor 31 is connected to the input shaft of the reducer 32. The first pickup 41 and the second pickup 42 are disposed on the output shaft of the reducer 32. The output shaft of the reducer 32 is the aforementioned rotating shaft.

[0096] Since the combination of the rotary motor 31 and the speed reducer 32 can greatly improve the accuracy and stability of the movement of the rotating assembly 3, the accuracy and stability of the position interchanging of the first battery cell 5 and the second battery cell 6 through the rotating assembly 3 can be improved, and the position accuracy between the paired first battery cell 5 and second battery cell 6 can also be improved, which is beneficial to ensuring the pairing accuracy of the first battery cell 5 and the second battery cell 6.

[0097] Specifically, in the embodiment, the rotating assembly 3 further comprises a rigid connecting plate 33, the rotary motor 31 is mounted on the rigid connecting plate 33, and the rigid connecting plate 33 is arranged on the moving module 2, that is, the rotary motor 31 is indirectly arranged on the moving module 2 through the rigid connecting plate 33.

[0098] Since the rigid connecting plate 33 can be mounted on the rotary motor 31, the setting of the rotating assembly 3 on the moving module 2 is facilitated through the rigid connecting plate 33, and the reliability of the setting of the rotating assembly 3 on the moving module 2 can be ensured through the rigid connecting plate 33.

[0099] In other embodiments, the rotary motor 31 can be directly arranged on the moving module 2. In this way, the rigid connecting plate 33 is not required to be arranged, so that the structure of the rotating assembly 3 can be simplified, and the manufacturing cost of the rotating assembly 3 can be reduced.

[0100] For the rotating assembly 3, in another embodiment, the rotating assembly 3 can comprise a rotary motor 31, and the first pickup 41 and the second pickup 42 are arranged on the output shaft of the rotary motor 31, that is, the output shaft of the rotary motor 31 is the rotating shaft. In this way, since the speed reducer 32 is not arranged, the structure of the rotating assembly 3 can be simplified, and the manufacturing cost of the rotating assembly 3 can be reduced.

[0101] Further, as shown in Figs. Figure 4 , Figure 5 and Figure 6 , the rotating assembly 3 further comprises a pickup mounting plate 34, the pickup mounting plate 34 is arranged on the output shaft of the speed reducer 32, the length direction (X-axis direction in Fig. Figure 6 ) of the pickup mounting plate 34 is perpendicular to the extension direction (Y-axis direction in Fig. Figure 6 ) of the rotating shaft, and the first pickup 41 and the second pickup 42 are arranged on the pickup mounting plate 34 and located on both sides of the output shaft of the speed reducer 32 along the length direction of the pickup mounting plate 34.

[0102] By arranging the pickup mounting plate 34, not only can the first pickup 41 and the second pickup 42 be indirectly arranged on the output shaft of the speed reducer 32, but also the setting area of the first pickup 41 and the second pickup 42 at the output shaft of the speed reducer 32 can be increased, and the setting of the first pickup 41 and the second pickup 42 at the output shaft of the speed reducer 32 is facilitated.

[0103] For the pickup mounting plate 34, specifically, as shown in Figure 4 and Figure 5 , a flange structure 341 for connecting with the output shaft of the speed reducer 32 is arranged on the pickup mounting plate 34, the center of the flange structure 341 is a rotation axis 342, and the rotation axis 342 is on the axis of the output shaft of the speed reducer 32, that is, the rotation axis 342 is on the axis of the rotation shaft of the rotation assembly 3, as shown in Figure 3 , and since the first direction is parallel to the length direction of the pickup mounting plate 34, and the second direction is parallel to the width direction of the pickup mounting plate 34, the first pickup 41 and the second pickup 42 are arranged on both sides of the rotation axis 342 in the first direction, and are also arranged on both sides of the rotation axis 342 in the second direction.

[0104] For the rotation assembly 3, in other embodiments, the rotation assembly 3 can not include the pickup mounting plate 34, in which case the first pickup 41 and the second pickup 42 can form an integral structure, and the output shaft of the speed reducer 32 is directly connected to the integral structure. By arranging in this way, the structure of the rotation assembly 3 can be simplified to some extent, which is conducive to reducing the manufacturing cost of the rotation assembly 3.

[0105] For the rotary motor 31 and the speed reducer 32, further, in the present embodiment, the speed reducer 32 is a harmonic speed reducer, and the rotary motor 31 is a rotary servo motor.

[0106] Since the harmonic speed reducer can increase the torque output by the rotary motor 31 to several times, the rotation assembly 3 can withstand more load through the harmonic speed reducer, thereby facilitating the driving of the pickup assembly 4 to rotate. Since the rotary servo motor has high-precision position control capability, the positions of the first pickup 41 and the second pickup 42 during rotation can be more accurately controlled through the rotary servo motor, thereby also being able to more accurately control the positions of the first battery cell 5 and the second battery cell 6 during rotation. Since the combination of the harmonic speed reducer and the rotary servo motor can greatly improve the efficiency and performance of the rotation assembly 3, the rotation assembly 3 can not only further improve the pairing efficiency of the battery cells, but also improve the performance of the battery cell pairing system.

[0107] In another embodiment, the speed reducer 32 is a worm gear speed reducer, and the rotary motor 31 is a rotary servo motor. Since the worm gear speed reducer has a small volume, the volume of the entire rotation assembly 3 can be reduced through the worm gear speed reducer, which is conducive to facilitating the arrangement and installation of the rotation assembly 3.

[0108] In yet another embodiment, the speed reducer 32 is a harmonic speed reducer, and the rotary motor 31 is a stepping motor. Since the stepping motor is low in cost, the manufacturing cost of the rotary assembly 3 can be reduced by using the stepping motor.

[0109] For the first pickup 41 and the second pickup 42, at least two of the first pickup 41 and the second pickup 42 are provided, and the number of the first pickup 41 is equal to the number of the second pickup 42.

[0110] By providing at least two of the first pickup 41 and the second pickup 42, at least four groups of battery cells can be paired in one pairing process, which is beneficial to further improve the pairing efficiency of the battery cells and further improve the production efficiency of the battery.

[0111] Specifically, in the embodiment, as shown in Figure 4 , Figure 5 and Figure 6 , two of the first pickup 41 and the second pickup 42 are provided, and the first pickup 41 and the second pickup 42 are both clamps. By providing two of the first pickup 41 and the second pickup 42, not only can four groups of battery cells be paired in one pairing process to ensure that more groups of battery cells can be paired, but also the number of the first pickup 41 and the second pickup 42 can be relatively small, which facilitates the setting and installation of the first pickup 41 and the second pickup 42, and also reduces the occupied space of the pickup assembly 4.

[0112] The first pickup 41 and the second pickup 42 formed by the clamps not only facilitate the pickup of the battery cells, but also can hold the battery cells more firmly, which is beneficial to avoid the battery cells from falling off.

[0113] In other embodiments, the first pickup 41 and the second pickup 42 can also be provided with one, three or more. The number of the first pickup 41 and the second pickup 42 is flexible, which can be determined according to the actual needs, and facilitates the number setting of the first pickup 41 and the second pickup 42.

[0114] In other embodiments, the first pickup 41 and the second pickup 42 can also be air nozzles. The first pickup 41 and the second pickup 42 formed by the air nozzles not only can firmly and stably pick up the battery cells, but also can avoid damaging the battery cells during the pickup.

[0115] As shown in Figure 3 , the moving module 2 includes a translation assembly 21 and a lifting assembly 22, the translation assembly 21 is provided on the rack 1, the lifting assembly 22 is provided on the translation assembly 21, and the rotary assembly 3 is provided on the lifting assembly 22.

[0116] Translation component 21 is used to drive the first pickup 41 and the second pickup 42 along the first horizontal direction ( Figure 3 The Y-axis direction of the movement and lifting assembly 22 is used to drive the first pickup 41 and the second pickup 42 along the vertical direction. Figure 3 The Z-axis direction of the device is raised and lowered to drive the first pickup 41 and the second pickup 42 to move to the first battery cell 5 and the second battery cell 6 respectively.

[0117] By using the translation component 21 and the lifting component 22, the degree of freedom of the moving module 2 to move the first pickup 41 and the second pickup 42 is increased, making it easier for the moving module 2 to move the first pickup 41 and the second pickup 42 to the first battery cell 5 and the second battery cell 6.

[0118] In another embodiment, the moving module 2 includes a translation component 21, which is disposed on the frame 1, and a rotation component 3 is disposed on the translation component 21. In this way, since the lifting component 22 is not provided, the structural composition of the moving module 2 can be simplified, which is beneficial to the processing and manufacturing of the moving module 2, and at the same time, it can also reduce the manufacturing cost of the moving module 2.

[0119] In another embodiment, the moving module 2 includes a lifting assembly 22, which is disposed on the frame 1, and a rotating assembly 3 is disposed on the lifting assembly 22. In this way, since the translation assembly 21 is not provided, the structural composition of the moving module 2 can be simplified, which is beneficial to the processing and manufacturing of the moving module 2, and at the same time, it can reduce the manufacturing cost of the moving module 2.

[0120] Furthermore, such as Figure 3 As shown, the translation assembly 21 includes two sets disposed on the frame 1 and along the second horizontal direction ( Figure 3 Synchronous belt mechanisms 211 are spaced apart in the X-axis direction. Each synchronous belt mechanism 211 includes a synchronous belt 2111, which extends along a first horizontal direction and a second horizontal direction is perpendicular to the first horizontal direction.

[0121] The translation component 21 also includes a crossbeam 212 disposed between the two sets of synchronous belt mechanisms 211. The two ends of the crossbeam 212 are slidably engaged with the frame 1 along the first horizontal direction. The two ends of the crossbeam 212 are respectively connected to the synchronous belts 2111 in the two sets of synchronous belt mechanisms 211. The two sets of synchronous belt mechanisms 211 are used to drive the two synchronous belts 2111 to move along the first horizontal direction to drive the first pickup 41 and the second pickup 42 to move along the first horizontal direction. The lifting component 22 is disposed on the crossbeam 212.

[0122] Since the synchronous belt mechanism 211 has buffering and shock absorption capability, through the driving of the synchronous belt mechanism 211, the vibration of the translation assembly 21 can be reduced, which is beneficial to ensure the stability of the movement of the translation assembly 21. At the same time, since the synchronous belt mechanism 211 is easy to maintain and has low maintenance cost, the maintenance of the translation assembly 21 is facilitated, and the maintenance cost is reduced.

[0123] Since the two groups of synchronous belt mechanisms 211 are arranged in the second horizontal direction, by arranging the cross beam 212 connected with each synchronous belt mechanism 211 at two ends, the arrangement of the lifting assembly 22 on the translation assembly 21 is facilitated, and the arrangement of the lifting assembly 22 on the cross beam 212 is also beneficial to avoid the movement interference between the lifting assembly 22 and the synchronous belt mechanism 211, which is beneficial to ensure the normal operation of the moving module 2.

[0124] For the translation assembly 21, specifically, Figure 3 and Figure 7 As shown, the translation assembly 21 further comprises a translation motor 213, and the synchronous belt mechanism 211 further comprises two synchronous pulleys 2112 arranged in the first horizontal direction, the synchronous belt 2111 is sleeved on the two synchronous pulleys 2112, and the driving pulley in the two synchronous pulleys 2112 is connected with the output shaft of the translation motor 213 through a transmission shaft 214. In this way, when the translation motor 213 operates, the synchronous pulley 2112 can be driven to rotate through the transmission shaft 214, thereby driving the synchronous belt 2111 to move in the first horizontal direction. At the same time, the cross beam 212 connected with the synchronous belt 2111 also moves in the first horizontal direction, and the cross beam 212 can indirectly drive the first picking piece 41 and the second picking piece 42 to move in the first horizontal direction through the lifting assembly 22 and the rotating assembly 3.

[0125] In other embodiments, the translation assembly 21 can further comprise a translation electric cylinder, the translation electric cylinder is arranged on the rack 1, the lifting assembly 22 is arranged on the output end of the translation electric cylinder, and the output end of the translation electric cylinder moves in the first horizontal direction. In this way, the first picking piece 41 and the second picking piece 42 can be driven to move in the first horizontal direction through the translation electric cylinder. In this way, the structure of the translation assembly 21 can be simplified, and the processing and manufacturing of the translation assembly 21 are facilitated.

[0126] Further, as shown in Figure 3 The two ends of the cross beam 212 are provided with guide structures 7 between the rack 1, and the guide structures 7 are used for guiding the sliding of the two ends of the cross beam 212 in the first horizontal direction.

[0127] Through the guidance of the two ends of the cross beam 212 by the guide structures 7, the stability of the movement of the cross beam 212 in the first horizontal direction can be ensured, and the stability of the movement of the first picking piece 41 and the second picking piece 42 in the first horizontal direction can also be ensured.

[0128] Specifically, in the present embodiment, as shown in Figure 7 the guiding structure 7 comprises a guide rail 71 arranged on the rack 1 and a sliding block 72 guidingly assembled on the guide rail 71, and the length of the guide rail 71 extends along the first horizontal direction, and the sliding block 72 is connected with the end of the cross beam 212, so that the end of the cross beam 212 is guidingly assembled on the guide rail 71 through the sliding block 72. The guiding structure 7 composed of the guide rail 71 and the sliding block 72 simplifies the specific structural form of the guiding structure 7, which is conducive to facilitating the processing and manufacturing of the guiding structure 7.

[0129] In another embodiment, the guiding structure 7 can also comprise a sliding groove arranged on the rack 1 and a sliding block arranged on the end of the cross beam 212 and guidingly matched with the sliding groove. The guiding structure 7 composed of the sliding groove and the sliding block can further ensure the stability of the movement of the cross beam 212 along the first horizontal direction, and thus can further ensure the stability of the movement of the first picking piece 41 and the second picking piece 42 along the first horizontal direction.

[0130] In yet another embodiment, the two ends of the cross beam 212 and the rack 1 can also not be provided with the guiding structure 7, in which case the two ends of the cross beam 212 and the rack 1 are slidingly matched. Since the guiding structure 7 is not provided, the structure between the cross beam 212 and the rack 1 can be simplified, which is conducive to facilitating the structure between the cross beam 212 and the rack 1.

[0131] For the lifting assembly 22, in the present embodiment, as shown in Figure 3 the lifting assembly 22 comprises a lifting servo motor 221 and a screw nut mechanism, and the servo motor 221 is used to drive the screw nut mechanism to act along the vertical direction, and the rotating assembly 3 is arranged on the screw nut mechanism, that is, the rigid connecting plate 33 is arranged on the screw nut mechanism. Through the lifting servo motor 221 and the screw nut mechanism, the motion control precision of the lifting assembly 22 can be improved, and thus the motion precision of the first picking piece 41 and the second picking piece 42 in the vertical direction can be improved.

[0132] In other embodiments, the lifting assembly 22 can also comprise a lifting electric cylinder, which has an output end outputting action along the vertical direction, and the rotating assembly 3 is arranged on the output end of the lifting electric cylinder, that is, the rigid connecting plate 33 is arranged on the output end of the lifting electric cylinder. In this way, the structure of the lifting assembly 22 can be simplified, which not only facilitates the processing and manufacturing of the lifting assembly 22, but also can reduce the manufacturing cost of the lifting assembly 22.

[0133] As shown in Figure 1 and Figure 2 the cell pairing system further comprises a first incoming material logistics line 8, a second incoming material logistics line 9, a material removal logistics line 10 and a transfer assembly (not shown in the figure).

[0134] Among them, asFigure 8 As shown in the figure, the first incoming material flow line 8 is used to transport the first battery cell 5, and the first battery cell 5 includes a first set of first battery cells 51 and a second set of first battery cells 52 in one-to-one correspondence. The second incoming material flow line 9 is used to transport the second battery cell 6, and the second battery cell 6 includes a first set of second battery cells 61 and a second set of second battery cells 62 in one-to-one correspondence.

[0135] As shown in the figure, the moving module 2 is used to drive the first pickup 41 and the second pickup 42 to move to the first incoming material flow line 8 and the second incoming material flow line 9 respectively to pick up the first set of first battery cells 51 and the first set of second battery cells 61 respectively. Figure 2 Figure 9 As shown in the figure, the moving module 2 is used to drive the first pickup 41 and the second pickup 42 to move to the first incoming material flow line 8 and the second incoming material flow line 9 respectively to pick up the first set of first battery cells 51 and the first set of second battery cells 61 respectively.

[0136] The transfer assembly is used to transfer the second set of first battery cells 52 on the first incoming material flow line 8 and the second set of second battery cells 62 on the second incoming material flow line 9 to the outgoing material flow line 10 (as shown in the figure), and the rotating assembly 3 is used to drive the first pickup 41 and the second pickup 42 to rotate around the above-mentioned rotating shaft to exchange the positions of the first set of first battery cells 51 and the first set of second battery cells 61. The moving module 2 is also used to drive the first pickup 41 and the second pickup 42 to move to the outgoing material flow line 10 respectively to make the first set of second battery cells 61 and the second set of first battery cells 52 be paired, and the first set of first battery cells 51 and the second set of second battery cells 62 be paired (as shown in the figure). Figure 10 Figure 11 As shown in the figure, the moving module 2 is used to drive the first pickup 41 and the second pickup 42 to move to the first incoming material flow line 8 and the second incoming material flow line 9 respectively to pick up the first set of first battery cells 51 and the first set of second battery cells 61 respectively.

[0137] Since the first incoming material flow line 8 transporting the first battery cell 5 and the second incoming material flow line 9 transporting the second battery cell 6 are both provided with the transfer assembly between the transfer assembly and the outgoing material flow line 10, and the transfer assembly is used to transfer the second set of first battery cells 52 on the first incoming material flow line 8 and the second set of second battery cells 62 on the second incoming material flow line 9 to the outgoing material flow line 10, therefore, after the moving module 2 drives the first pickup 41 and the second pickup 42 to move to the outgoing material flow line 10 respectively, the picked first set of second battery cells 61 and the second set of first battery cells 52 transferred to the outgoing material flow line 10 can be paired, and the picked first set of first battery cells 51 and the second set of second battery cells 62 transferred to the outgoing material flow line 10 can also be paired, that is, the first battery cell 5 and the second battery cell 6 are paired on the outgoing material flow line 10.

[0138] As can be seen from the above, the pairing of the first battery cell 5 and the second battery cell 6 will not affect the transportation of the battery cells on the first incoming material flow line 8 and the second incoming material flow line 9, and the first incoming material flow line 8 and the second incoming material flow line 9 can continue to transport the first battery cell 5 and the second battery cell 6 respectively, which is conducive to further improving the pairing efficiency of the battery cells, and further improving the production efficiency of the battery, and is conducive to further meeting the customer's high-efficiency battery production demand.

[0139] ​​In another embodiment, the transfer assembly can not be provided, in which case, after the first group of first battery cells 51 and the first group of second battery cells 61 are exchanged in position by the rotating assembly 3, the pairing of the first group of second battery cells 61 and the second group of first battery cells 52, and the pairing of the first group of first battery cells 51 and the second group of second battery cells 62 can be performed on the first incoming material flow line 8 and the second incoming material flow line 9, respectively. After the pairing is completed, the first pick-up piece 41 and the second pick-up piece 42 are used to pick up the paired battery cell groups on the first incoming material flow line 8 and the second incoming material flow line 9, respectively, and then the moving module 2 is used to drive the first pick-up piece 41 and the second pick-up piece 42 to move to the outgoing material flow line 10, so as to place the paired battery cell groups on the outgoing material flow line 10. Since the transfer assembly is not provided, the structural composition of the battery cell pairing system can be simplified, which is conducive to facilitating the processing and manufacturing of the battery cell pairing system, and also helps to reduce the manufacturing cost.

[0140] In yet another embodiment, the first incoming material flow line 8 and the second incoming material flow line 9 can not be provided, or the outgoing material flow line 10 can not be provided. In this case, other conveying devices outside the battery cell pairing system can be used to convey the first battery cells 5 and the second battery cells 6, or other conveying devices outside the battery cell pairing system can be used to convey the paired battery cell groups. Since the incoming material flow line or the outgoing material flow line 10 is not provided, the structural composition of the battery cell pairing system can also be simplified, which is also conducive to facilitating the processing and manufacturing of the battery cell pairing system, and also helps to reduce the manufacturing cost.

[0141] Further, as shown in Figure 8 the first incoming material flow line 8 and the second incoming material flow line 9 are arranged in line, and the conveying direction of the first incoming material flow line 8 and the conveying direction of the second incoming material flow line 9 are opposite.

[0142] In this way, the occupied space of the first incoming material flow line 8 and the second incoming material flow line 9 can be reduced, which is conducive to facilitating the arrangement of the first incoming material flow line 8 and the second incoming material flow line 9.

[0143] In another embodiment, the first incoming material flow line 8 and the second incoming material flow line 9 are parallel but not in line, and the conveying direction of the first incoming material flow line 8 and the conveying direction of the second incoming material flow line 9 are opposite. In this way, the arrangement relationship between the first incoming material flow line 8 and the second incoming material flow line 9 can be simplified to a certain extent, which is further conducive to facilitating the arrangement between the first incoming material flow line 8 and the second incoming material flow line 9.

[0144] In yet another embodiment, the extension line of the first incoming material flow line 8 intersects with the extension line of the second incoming material flow line 9, and the conveying directions of the two are also intersected. In this way, the arrangement relationship between the first incoming material flow line 8 and the second incoming material flow line 9 can be further simplified, and the arrangement between the first incoming material flow line 8 and the second incoming material flow line 9 is facilitated.

[0145] Further, as shown in Figure 8 , the outgoing material flow line 10 is arranged in parallel with the first incoming material flow line 8.

[0146] Since the first incoming material flow line 8 and the second incoming material flow line 9 are arranged in the same line, the outgoing material flow line 10 is arranged in parallel with the first incoming material flow line 8 and the second incoming material flow line 9. In this way, the occupied space of the incoming material flow line and the outgoing material flow line 10 can be reduced, and the arrangement of the incoming material flow line and the outgoing material flow line 10 is facilitated.

[0147] In other embodiments, the extension line of the outgoing material flow line 10 intersects with the extension line of the first incoming material flow line 8, that is, the extension line of the outgoing material flow line 10 intersects with the extension line of the second incoming material flow line 9. In this way, the arrangement relationship between the incoming material flow line and the outgoing material flow line 10 can be simplified, and the arrangement between the incoming material flow line and the outgoing material flow line 10 is facilitated.

[0148] As shown in Figure 10 , the outgoing material flow line 10 includes a first outgoing material flow line 101 and a second outgoing material flow line 102, and the first outgoing material flow line 101 and the second outgoing material flow line 102 are arranged in the same line and the conveying directions of the two are opposite.

[0149] Through the first outgoing material flow line 101 and the second outgoing material flow line 102, the completed battery cell group can be conveyed to different next process equipment for processing, and different processing equipment can be used in the next process, which is beneficial to further improve the production efficiency of the battery. The first outgoing material flow line 101 and the second outgoing material flow line 102 with opposite conveying directions can reduce the occupied space of the first outgoing material flow line 101 and the second outgoing material flow line 102, and further facilitate the arrangement of the first outgoing material flow line 101 and the second outgoing material flow line 102.

[0150] In another embodiment, the first outgoing material flow line 101 and the second outgoing material flow line 102 are parallel but not in the same line, and the conveying directions of the first outgoing material flow line 101 and the second outgoing material flow line 102 are opposite. In this way, the arrangement relationship between the first outgoing material flow line 101 and the second outgoing material flow line 102 can be simplified to a certain extent, and the arrangement between the first outgoing material flow line 101 and the second outgoing material flow line 102 is facilitated.

[0151] In yet another embodiment, the extension of the first material removal logistics line 101 and the extension of the second material removal logistics line 102 intersect, and the conveying directions of the two also intersect. In this way, the arrangement relationship between the first material removal logistics line 101 and the second material removal logistics line 102 can be further simplified, thereby facilitating the arrangement between the first material removal logistics line 101 and the second material removal logistics line 102.

[0152] In other embodiments, the material removal logistics line 10 can have one logistics line. In this way, the structural composition of the material removal logistics line 10 can be simplified, thereby facilitating the processing and manufacturing of the material removal logistics line 10.

[0153] As shown in Figure 8 and Figure 10 , the battery cell pairing system further includes a first tray 20 and a second tray 30, the first tray 20 being configured to carry the first battery cell 5, and the second tray 30 being configured to carry the second battery cell 6.

[0154] The first tray 20 has a first picking station on the first incoming logistics line 8 for the first picking member 41 to pick the first battery cell 5, the second tray 30 has a second picking station on the second incoming logistics line 9 for the second picking member 42 to pick the second battery cell 6, and the first tray 20 and the second tray 30 have a pairing station on the material removal logistics line 10 for the first battery cell 5 and the second battery cell 6 to be paired.

[0155] The first tray 20 and the second tray 30 facilitate the carrying of the first battery cell 5 and the second battery cell 6 on the corresponding logistics line, while avoiding the movement of the first battery cell 5 and the second battery cell 6, ensuring the stability of the position of the first battery cell 5 and the second battery cell 6 on the corresponding logistics line, thereby facilitating the picking of the corresponding battery cell by the corresponding picking member. The first tray 20 and the second tray 30 facilitate the picking of the corresponding battery cell by the corresponding picking member through the picking station on the corresponding incoming logistics line, and the pairing of the battery cell group through the pairing station on the material removal logistics line 10.

[0156] In another embodiment, the first tray 20 and the second tray 30 can not be provided, and the first battery cell 5 and the second battery cell 6 are directly carried on the corresponding logistics line. In this way, the composition of the battery cell pairing system can be simplified, thereby reducing the manufacturing cost of the battery cell pairing system.

[0157] Further, as shown in Figure 8 , the length direction of the first tray 20 is perpendicular to the length direction of the first incoming logistics line 8, and the first group of first battery cells 51 and the second group of first battery cells 52 are arranged along the length direction of the first tray 20 with the tabs of the two facing each other.

[0158] The length direction of the second tray 30 is perpendicular to the length direction of the second incoming material flow line 9, and the first group of second battery cells 61 and the second group of second battery cells 62 are arranged along the length direction of the second tray 30 and have their tabs opposite to each other.

[0159] In this way, the first battery cells 5 and the second battery cells 6 can occupy less space in the width direction of the tray, which facilitates the arrangement of the first battery cells 5 and the second battery cells 6 on the corresponding tray, and the opposite arrangement of the tabs facilitates the pairing of the first battery cells 5 and the second battery cells 6 after they are rotated and exchanged.

[0160] In another embodiment, the length direction of the first tray 20 is parallel to the length direction of the first incoming material flow line 8, and the length direction of the second tray 30 is parallel to the length direction of the second incoming material flow line 9. In this way, the distance between the first tray 20 and the second tray 30 and the edge of the corresponding flow line can be increased, thereby avoiding interference between the tray and the edge of the flow line, and facilitating the normal conveying of the tray on the flow line.

[0161] Embodiment Two

[0162] The application also provides a battery cell pairing method, which can be implemented based on any of the battery cell pairing systems in the above embodiments or other battery cell pairing systems different from any of the battery cell pairing systems in the above embodiments. The present embodiment is described based on implementation based on any of the battery cell pairing systems in the above embodiments.

[0163] Figure 12 is a flowchart of a battery cell pairing method provided by the present embodiment, referring to Figure 12 , the method comprises:

[0164] Step 301: using the first incoming material flow line 8 to convey the first battery cells 5 Figure 8 , the first battery cells 5 include a first group of first battery cells 51 and a second group of first battery cells 52 in one-to-one correspondence; using the second incoming material flow line 9 to convey the second battery cells 6 Figure 8 , the second battery cells 6 include a first group of second battery cells 61 and a second group of second battery cells 62 in one-to-one correspondence.

[0165] Step 302: driving the first picking member 41 and the second picking member 42 in the battery cell pairing system to move to the first incoming material flow line 8 and the second incoming material flow line 9, respectively, to pick up the first group of first battery cells 51 and the first group of second battery cells 61, respectively Figure 9 .

[0166] Step 303: Rotating the first pickup piece 41 and the second pickup piece 42 around the rotation axis by the rotating assembly 3 in the battery cell pairing system to exchange the positions of the first group of first battery cells 51 and the first group of second battery cells 61.

[0167] Step 304: Pairing the first group of second battery cells 61 and the second group of first battery cells 52, pairing the first group of first battery cells 51 and the second group of second battery cells 62 (as shown). Figure 11

[0168] Since the first pickup piece 41 and the second pickup piece 42 can pick up the first battery cell 5 and the second battery cell 6 respectively, through the joint picking up of the first pickup piece 41 and the second pickup piece 42, at least two groups of battery cell groups composed of the first battery cell 5 and the second battery cell 6 can be paired in one pairing process, so compared with the related art that only one group of battery cell groups can be paired in one pairing process, through the present application, it is beneficial to improve the pairing efficiency of the battery cell, and further improve the production efficiency of the battery, which is beneficial to meet the customer's demand for efficient battery production.

[0169] Specifically, step 302: moving the first pickup piece 41 and the second pickup piece 42 to the first incoming logistics line 8 and the second incoming logistics line 9 respectively by the moving module 2 to pick up the first group of first battery cells 51 and the first group of second battery cells 61 respectively, including:

[0170] Step 3021: moving the first pickup piece 41 and the second pickup piece 42 to the first incoming logistics line 8 and the second incoming logistics line 9 along the first horizontal direction respectively by the translation assembly 21.

[0171] Step 3022: moving the first pickup piece 41 and the second pickup piece 42 downward (Z1 direction in the figure) along the vertical direction by 100mm by the lifting assembly 22, so that the first pickup piece 41 and the second pickup piece 42 pick up the first group of first battery cells 51 and the first group of second battery cells 61 respectively. Figure 6 Step 3022: moving the first pickup piece 41 and the second pickup piece 42 upward (Z2 direction in the figure) along the vertical direction by 100mm by the lifting assembly 22.

[0172] Figure 6

[0173] Wherein, the movement distance of the first pickup piece 41 and the second pickup piece 42 along the vertical direction can also be other sizes, specifically, it needs to be determined according to the actual situation, and this embodiment will not be described in detail.

[0174] Specifically, the present application provides a method of "transferring the second group of first battery cells 52 on the first incoming logistics line 8 and the second group of second battery cells 62 on the second incoming logistics line 9 to the outgoing logistics line 10 by using the transfer assembly", including: ​​​

[0175] As shown in Figure 10 , the second group of first battery cells 52 on the first incoming logistics line 8 is transferred to the first outgoing logistics line 101 using the transfer assembly, and the second group of second battery cells 62 on the second incoming logistics line 9 is transferred to the second outgoing logistics line 102 using the transfer assembly.

[0176] Further, step 304: pairing the first group of second battery cells 61 and the second group of first battery cells 52, and pairing the first group of first battery cells 51 and the second group of second battery cells 62, comprises:

[0177] Step 3041: using the transfer assembly in the battery cell pairing system to transfer the second group of first battery cells 52 on the first incoming logistics line 8 and the second group of second battery cells 62 on the second incoming logistics line 9 to the outgoing logistics line 10 in the battery cell pairing system.

[0178] Step 3042: moving the first pickup 41 and the second pickup 42 to the outgoing logistics line 10 by the movement module 2 to pair the first group of second battery cells 61 and the second group of first battery cells 52, and pair the first group of first battery cells 51 and the second group of second battery cells 62.

[0179] Since the pairing of the first battery cells 5 and the second battery cells 6 is performed on the outgoing logistics line 10, the pairing of the first battery cells 5 and the second battery cells 6 does not affect the transportation of the battery cells on the first incoming logistics line 8 and the second incoming logistics line 9, and the first incoming logistics line 8 and the second incoming logistics line 9 can continue to transport the first battery cells 5 and the second battery cells 6 respectively, which is conducive to further improving the pairing efficiency of the battery cells, and further improving the production efficiency of the battery, and is conducive to further meeting the customer's high-efficiency battery production demand.

[0180] Specifically, step 3042: moving the first pickup 41 and the second pickup 42 to the outgoing logistics line 10 by the movement module 2 to pair the first group of second battery cells 61 and the second group of first battery cells 52, and pair the first group of first battery cells 51 and the second group of second battery cells 62, comprises:

[0181] Step 30421: moving the first pickup 41 and the second pickup 42 700mm along the positive direction (Y1 direction) of the first horizontal direction by the translation assembly 21 to move the first pickup 41 and the second pickup 42 above the outgoing logistics line 10. Figure 7

[0182] ​Step 30422: The lifting assembly 22 drives the first pickup 41 and the second pickup 42 to move vertically downward by 100mm, so as to transfer the first group of first battery cells 51 to the second unloading material line 102 and the first group of second battery cells 61 to the first unloading material line 101, so that the first group of second battery cells 61 and the second group of first battery cells 52 are paired. Figure 11 (As shown).

[0183] The movement distance of the first pickup 41 and the second pickup 42 along the vertical and first horizontal directions can also be other distances. Specifically, it needs to be determined according to the actual situation, which will not be described in detail in this embodiment.

[0184] In another embodiment, step 304: pairing the first group of second battery cells 61 and the second group of first battery cells 52, and pairing the first group of first battery cells 51 and the second group of second battery cells 62, includes:

[0185] The first group of second battery cells 61 and the second group of first battery cells 52 are paired on the first incoming material flow line 8, and the first group of first battery cells 51 and the second group of second battery cells 62 are paired on the second incoming material flow line 9.
