[0032] like Figure 1 As shown, the present application provides a processing device 100 for a battery cell, and the processing device 100 includes a carrier 11 and a press assembly 12. Specifically, the carrier 11 has a bearing surface 111 for bearing a conductive connector 200 and a battery cell 300. Among them, the press assembly 12 at least partially acts on the battery cell 300, so that the battery cell 300 is fixed on the bearing surface 111, and the battery cell 300 can contact the conductive connector 200 on the bearing surface 111. With such a configuration, there is no need to install an adsorption device on the carrier 11, that is, there is no need to open an adsorption hole on the carrier 11, and there is no need to set an adsorption pipe in the carrier 11, which is conducive to simplifying the structure of the carrier 11, and further facilitates the processing and maintenance of the carrier 11. In addition, by setting the press assembly 12, the convenience of fixing the battery cell 300 on the carrier 11 can be improved. Furthermore, such a configuration can also prevent the battery cell 300 from falling off the carrier 11 due to insufficient adsorption force of the adsorption holes or blockage of the adsorption holes, thereby facilitating improving the fixing stability of the battery cell 300 on the carrying surface 111 .

[0033] As an embodiment, the press assembly 12 is detachably connected to the carrier 11. Such a configuration can facilitate the assembly between the press assembly 12 and the carrier 11, so that the press assembly 12 can be flexibly disassembled and assembled according to production requirements, thereby improving the assembly flexibility between the press assembly 12 and the carrier 11, so as to facilitate the fixation of the press assembly 12 to the battery cell 300.

[0034] As an optional implementation, the press assembly 12 is magnetically connected or adsorbed to the bearing surface 111 so that the press assembly 12 can be detachably connected to the bearing surface 111 .

[0035] Exemplarily, a first magnetic member (not shown) is provided on the bearing surface 111, and a second magnetic member (not shown) is provided on the press assembly 12. Through the magnetic connection between the first magnetic member and the second magnetic member, the press assembly 12 can be connected to the bearing surface 111, so that the press assembly 12 can cooperate with the bearing surface 111 to fix the battery cell 300, so that the battery cell 300 and the conductive connector 200 are in contact. In addition, the magnetic connection method is also conducive to disassembly of the press assembly 12 and the bearing surface 111, so as to facilitate disassembly and assembly between the press assembly 12 and the bearing surface 111, so as to improve the assembly flexibility between the press assembly 12 and the carrier 11. As another embodiment, a magnetic member is provided on the bearing surface 111, and the press assembly 12 can be a metal member, so that the press assembly 12 can be connected to the bearing surface 111 through the magnetic connection between the magnetic member and the metal member. Among them, the magnetic member on the bearing surface 111 can be an electromagnet. This application does not limit the method of magnetic connection between the bearing surface 111 and the press assembly 12.

[0036] Exemplarily, adsorption holes (not shown) are provided on the bearing surface 111, and negative pressure can be formed in the adsorption holes so that the press assembly 12 can be fixed on the bearing surface 111. It should be noted that the adsorption holes are only arranged in a part of the bearing surface 111 connected to the press assembly 12, and do not need to be arranged in the entire area of ​​the bearing surface 111. For example, it is only necessary to arrange the adsorption holes on both sides of the bearing surface 111 that are not in contact with the battery cell 300. Through the above arrangement, the adsorption pipe in the carrier 11 can be simplified, thereby simplifying the structure of the carrier 11.

[0037] like Figure 1 As shown, as an embodiment, the press assembly 12 has a pressing surface 121, and the pressing surface 121 is arranged on a side of the press assembly 12 close to the carrier 11. Such an arrangement enables the press assembly 12 to drive the pressing surface 121 to move, so that the pressing surface 121 abuts against the carrier surface 111, thereby pressing the battery cell 300.

[0038] Specifically, the pressing surface 121 has the same shape as the bearing surface 111. This arrangement can improve the fit between the pressing surface 121 and the bearing surface 111, thereby avoiding a gap between the pressing surface 121 and the bearing surface 111, which would cause the press assembly 12 to be unable to press the battery cell 300, thereby preventing the battery cell 300 from falling off from the gap, thereby facilitating the pressing stability of the press assembly 12 on the battery cell 300 on the bearing surface 111, and further facilitating the contact stability between the battery cell 300 and the conductive connector 200.

[0039] As an optional implementation, the bearing surface 111 and the pressing surface 121 are both set to be planes. This arrangement can avoid the bearing surface 111 and the pressing surface 121 being not tightly fitted when they are in different planes, thereby improving the tightness of the fitting between the pressing surface 121 and the bearing surface 111, and further improving the pressing stability of the pressing surface 121 on the battery cell 300 on the bearing surface 111.

[0040] As another optional implementation, the bearing surface 111 is set as a curved surface that convexes toward the pressing surface 121, and the pressing surface 121 is set as a curved surface that is concave away from the bearing surface 111. In this way, the pressing surface 121 and the bearing surface 111 set as curved surfaces can make the battery cell 300 slightly deformed when the presser assembly 12 fixes the battery cell 300 so that the battery cell 300 forms a curved surface, so that the battery cell 300 can be more closely fitted with the conductive connector 200. In the present application, the battery cell 300 and the conductive connector 200 are fixed by welding. Through the above-mentioned setting, when welding the battery cell 300 and the conductive connector 200, the cold welding between the battery cell 300 and the conductive connector 200 can be reduced, thereby improving the welding efficiency between the battery cell 300 and the conductive connector 200. In addition, the battery cell 300 with a curved surface can avoid the battery cell 300 from being overheated, resulting in warping or cracking, which is conducive to improving the service life and processing quality of the battery cell 300.

[0041] As an embodiment, the press assembly 12 is a rigid member so that the pressing surface 121 has no deformation margin. This arrangement can avoid the deformation gap between the pressing surface 121 and the bearing surface 111, thereby improving the tightness of the pressing surface 121 and the bearing surface 111, and further improving the pressing stability of the pressing surface 121 on the battery cell 300 on the bearing surface 111.

[0042] like Figure 2As shown, as another embodiment, the press assembly 12 has a deformable portion 122, and the deformable portion 122 is arranged on the side of the press assembly 12 close to the carrier 11. The deformable portion 122 has a deformable margin, and the deformable portion 122 forms a pressing surface 121. In this way, the deformable deformable portion 122 can enable the pressing surface 121 to adapt to various shapes of bearing surfaces 111, thereby improving the adaptability of the press assembly 12 to the bearing surface 111 on the carrier 11. In addition, the deformable pressing surface 121 can better fit the bearing surface 111, thereby improving the fit between the pressing surface 121 and the bearing surface 111. In some embodiments, the deformable portion 122 is a deformable airbag arranged on the side of the press assembly 12 close to the carrier 11. Specifically, the pressing surface 121 is formed on the side of the airbag close to the bearing surface 111. In this way, the airbag can be compressed and deformed into any shape to improve the fit between the pressing surface 121 and the bearing surface 111, thereby improving the fixing effect of the press assembly 12 on the battery cell 300. It should be noted that in this application, the deformation part 122 can also be other structures with deformation ability, and this application does not limit it.

[0043] As an embodiment, a positioning groove 1111 is provided on the bearing surface 111, and the positioning groove 1111 is configured to limit the position of the conductive connector 200 on the bearing surface 111. In the present application, the conductive connector 200 is a welding strip, and the battery cells 300 can be connected to form a battery string through the welding strip. Through the above-mentioned arrangement, the positioning groove 1111 can be beneficial to the limited installation of the conductive connector 200 on the bearing surface 111, and can also prevent the conductive connector 200 from being offset on the bearing surface 111, so as to help limit the position of the conductive connector 200 and connect it with the battery cell 300. It can be understood that the conductive connector 200 can be a circular welding strip, a triangular welding strip, etc., and the present application does not limit the structural form of the conductive connector 200.

[0044] As an embodiment, the carrier 11 has rotational freedom, and a plurality of bearing surfaces 111 are provided, and the plurality of bearing surfaces 111 are distributed on the carrier 11 along the rotation direction of the carrier 11, and the positioning grooves 1111 are distributed on the plurality of bearing surfaces 111 in a spiral shape. In some embodiments, the carrier 11 may be a prism, and each surface of the prism is a bearing surface 111. With such a configuration, the bearing surface 111 formed by the prism can reduce the space occupancy rate of the carrier 11, which is conducive to the layout of more processing devices 100 in the production workshop, thereby improving the production efficiency of the production workshop. It should be noted that the carrier 11 may also be a tubular, cylindrical or other structure, and this application is not limited thereto, and it is only necessary that the carrier 11 has rotational freedom.

[0045] like Figure 3As shown, as an embodiment, the present application also discloses a processing method of a battery cell 300, the processing method comprising the following steps:

[0046] S1: The conductive connecting member 200 is wound on the carrying surface 111 of the carrier 11;

[0047] S2: The battery cell 300 is placed on the carrying surface 111 of the carrier 11;

[0048] S3 : The press assembly 12 acts on the battery cell 300 to fix the battery cell 300 on the carrying surface 111 , and enables the battery cell 300 to contact the conductive connector 200 on the carrying surface 111 .

[0049] Specifically, in step S1 , the conductive connector 200 may be arranged on the carrying surface 111 , which is beneficial for connecting the conductive connector 200 with the battery cell 300 , so that the battery cell 300 and the conductive connector 200 can form a battery string.

[0050] In step S2 , the battery cell 300 may be pre-positioned on the carrying surface 111 .

[0051] In step S3 , the press assembly 12 acts on the battery cell 300 through magnetic connection or adsorption connection, so that the pressing surface 121 on the press assembly 12 can cooperate with the bearing surface 111 to press and contact the battery cell 300 and the conductive connector 200 .

[0052] like Figure 4 As shown, as an embodiment, the processing device 100 further includes a movable driving mechanism 13, and the driving mechanism 13 is configured to move the press assembly 12. In this way, the driving mechanism 13 can drive the press assembly 12 to move, so that the pressing surface 121 on the press assembly 12 can cooperate with the bearing surface 111 of the carrier 11 to press and contact the battery cell 300 and the conductive connector 200.

[0053] Specifically, the driving mechanism 13 includes a first moving member 131 and a second moving member 132, and both the first moving member 131 and the second moving member 132 are movable. Among them, the first moving member 131 is configured to be able to move the press assembly 12, and the second moving member 132 is configured to be able to move the battery cell 300. In this way, the first moving member 131 can drive the battery cell 300 to be placed on the carrier 11, and then the second moving member 132 drives the press assembly 12 to move, so that the pressing surface 121 on the press assembly 12 can cooperate with the bearing surface 111 to press the battery cell 300 and the conductive connector 200.

[0054] In some embodiments, the first moving member 131 and the second moving member 132 can both be mechanical arms, the first moving member 131 is provided with a first suction cup, and the second moving member 132 is provided with a second suction cup. With such a configuration, the first suction cup can grab the battery cell 300, and then the first suction cup is driven to move by the mechanical arm, so that the first suction cup can drive the battery cell 300 to be placed on the bearing surface 111. In addition, the second suction cup can grab the press assembly 12, and then the second suction cup is driven to move by the mechanical arm, so that the second suction cup can drive the press to move, so that the press assembly 12 can cooperate with the bearing surface 111 to press the battery cell 300 and the conductive connector 200.

[0055] like Figure 4 As shown, as an embodiment, in order to connect the battery cell 300 with the conductive connector 200, the processing device 100 also includes a heating component 14, which is configured to transfer heat to the battery cell 300 through the press assembly 12, so that the battery cell 300 and the conductive connector 200 can be connected under heating. In this way, the battery cell 300 and the conductive connector 200 can be heated by the heating component 14, so that the battery cell 300 and the conductive connector 200 are welded. As an embodiment, the heating component 14 is located on the press assembly 12. In this way, the heat loss of the heating component 14 can be reduced, which is conducive to improving the welding efficiency of the battery cell 300 and the conductive connector 200.

[0056] As another embodiment, the heating component 14 is disposed near the press assembly 12. In this way, the heating component 14 and the press assembly 12 can be disposed separately, which is conducive to simplifying the structure of the press assembly 12 and reducing the weight of the press assembly 12, thereby facilitating the movement of the press assembly 12. In addition, by separating the heating component 14 and the press assembly 12, it is possible to prevent the heating component 14 from overheating the press assembly 12 and causing damage to the press assembly 12, thereby facilitating the service life of the press assembly 12.

[0057] Specifically, the heating assembly 14 is located on the side of the press assembly 12 away from the carrier 11. This arrangement can prevent the heating assembly 14 from interfering with the movement of the press assembly 12 toward the carrier 11, thereby facilitating the smoothness of the operation of the press assembly 12.

[0058] like Figure 4As shown, as an embodiment, in order to improve the connection efficiency of the press assembly 12 and the conductive connector 200, as another embodiment, the present application also discloses a press assembly 12, which is used to fix the battery cell 300 on the carrier 11. Specifically, the press assembly 12 is at least partially configured to be light-transmissive, so that the press assembly 12 has thermal conductivity. Through the above-mentioned configuration, the light-transmissive press assembly 12 can improve the heat conduction efficiency of the heating assembly 14 through the press assembly 12, thereby improving the heating efficiency of the heating assembly 14 to the battery cell 300 and the conductive connector 200, and then improving the welding efficiency of the battery cell 300 and the conductive connector 200.

[0059] In some embodiments, the heating component 14 is an infrared heater, and the infrared rays of the infrared heater can pass through the light-transmitting press assembly 12 and directly irradiate the battery cell 300 , thereby improving the heating efficiency of the heating component 14 on the battery cell 300 .

[0060] As an optional implementation, the press assembly 12 is at least partially made of a transparent material so that the press assembly 12 can transmit light. In some embodiments, the press assembly 12 is made of a transparent quartz material so that the press assembly 12 can transmit light, thereby improving the heating efficiency of the heating assembly 14 on the battery cell 300 and the conductive connector 200.

[0061] It should be noted that the press assembly 12 may also be made of other materials that are light-transmissive but not transparent, such as PVC (Polyvinyl chloride) plastic. It is understandable that the PVC plastic has light transmittance, so that the heating assembly 14 can heat the battery cell 300 and the conductive connector 200 through the PVC plastic. Therefore, in the present application, the press assembly 12 only needs to be light-transmissive, and the present application does not limit whether the press assembly 12 is made of a transparent material.

[0062] like Figure 5 As shown, as another optional implementation, the press assembly 12 at least partially has a mesh structure so that the press assembly 12 can transmit light. In this way, the mesh-structured press assembly 12 has a mesh so that the heating assembly 14 can heat the battery cell 300 and the conductive connector 200 through the mesh, thereby improving the heating efficiency of the heating assembly 14 on the battery cell 300 and the conductive connector 200.

[0063] In the present application, when the heating component 14 is disposed in the press component 12 or the heating component 14 is disposed close to the press component 12, the light-transmitting press component 12 enables the heating component 14 to heat the conductive connector 200 and the battery cell 300 through the press component 12, thereby improving the heating efficiency of the heating component 14 on the conductive connector 200 and the battery cell 300. Wherein, when the heating component 14 is disposed close to the press component 12, the heating component 14 is disposed on the side of the press component 12 away from the carrier 11. With such an arrangement, the heat of the heating component 14 can be conducted to the conductive connector 200 and the battery cell 300 after passing through the light-transmitting press component 12, thereby improving the heating efficiency of the heating component 14 in heating the conductive connector 200 and the battery cell 300.

[0064] like Figure 6 As shown, as another embodiment, the battery cell processing device 100 of the present application includes a carrier 11, a press assembly 12 and a heating assembly 14. The structures and operation processes of the carrier 11 and the press assembly 12 have been described above and will not be repeated here.

[0065] Specifically, the heating component 14 is located inside the carrier 11, and the heating component 14 is configured to heat and connect the battery cell 300 and the conductive connector 200. In this way, the heating component 14 can directly heat the battery cell 300 and the conductive connector 200 on the carrier 11, thereby eliminating the need for heat conduction through the press assembly 12, thereby improving the efficiency of the heating component 14 in heating the battery cell 300 and the conductive connector 200, so as to improve the welding efficiency of the battery cell 300 and the conductive connector 200. In some embodiments, the heating component 14 is an electric heating pipe, which is located inside the carrier 11 and can heat the carrier 11 so that the conductive connector 200 on the carrier 11 and the battery cell 300 can be welded.

[0066] It should be noted that, in the present embodiment, the press assembly 12 can be configured to be light-transmissive or light-impermeable, and the present application does not impose any limitation thereto.

[0067] like Figure 7 As shown, as an embodiment, the present application also discloses another processing method of a battery cell 300, the processing method comprising:

[0068] S1: The conductive connecting member 200 is wound on the carrying surface 111 of the carrier 11;

[0069] S2: The battery cell 300 is placed on the carrying surface 111 of the carrier 11;

[0070] S3: the pressing tool assembly 12 acts on the battery cell 300 to fix the battery cell 300 on the carrying surface 111 and enable the battery cell 300 to contact the conductive connecting member 200 on the carrying surface 111;

[0071] S4: The heating component 14 located in the carrier 11 heats the battery cell 300 and the conductive connecting member 200 so that the battery cell 300 and the conductive connecting member 200 are connected under heating.

[0072] In step S4 , the battery cell 300 is heated by the heating assembly 14 and then welded to the conductive connector 200 , so that the battery cell 300 and the conductive connector 200 form a battery string.

[0073] like Figure 8 As shown, as another embodiment, the battery cell processing device 100 of the present application includes a carrier 11 and a plurality of presser assemblies 12. The structure of the carrier 11 has been described above and will not be repeated here. In this embodiment, the carrier 11 also has a rotational degree of freedom, and a plurality of bearing surfaces 111 are provided, and the plurality of bearing surfaces 111 are distributed on the carrier 11 along the rotation direction of the carrier 11.

[0074] Specifically, two adjacent press assemblies 12 are movably connected, and a plurality of press assemblies 12 are stacked and at least partially located above the carrier 11. During the rotation of the carrier 11, the press assemblies 12 are configured to be able to move downward one by one, so that each press assembly 12 can move to a bearing surface 111, and each press assembly 12 can make a battery cell 300 contact the conductive connector 200 on the corresponding bearing surface 111. In this way, a plurality of press assemblies 12 can successively press the corresponding battery cells 300 and the conductive connector 200, so that a plurality of press assemblies 12 can press the corresponding battery cells 300, thereby improving the processing efficiency of the battery cells 300 and the conductive connector 200. In addition, the stacking of the press assemblies 12 can reduce the space occupancy of the press assemblies 12, so that more press assemblies 12 can be arranged, so that the press assemblies 12 can fix more battery cells 300, thereby improving the fixing efficiency of the press assemblies 12 on the battery cells 300.

[0075] It should be noted that, in the present embodiment, the angle between adjacent carrying surfaces 111 on the carrier 11 is an obtuse angle, and the obtuse angle is relatively large. Therefore, when one carrying surface 111 is in a horizontal state, the slope of the carrying surface 111 adjacent to it is smaller. Therefore, during the rotation of the carrier 11, the pressing tool assembly 12 and the battery cell 300 that have been arranged on the carrying surface 111 can be prevented from falling off, thereby improving the fixing stability of the battery cell 300 on the carrying surface 111.

[0076] Specifically, the structure of the press assembly 12 has been described above and will not be repeated here. Two adjacent stacked press assemblies 12 are defined as a first press and a second press, and the pressing surface 121 of the first press and the pressing surface 121 of the second press are arranged facing each other, or the pressing surface 121 of the first press and the pressing surface 121 of the second press are arranged back to back. With such an arrangement, after the multiple stacked press assemblies 12 are unfolded, the pressing surfaces 121 on the press assemblies 12 can face the same direction, that is, the pressing surfaces 121 on the press assemblies 12 are arranged toward the carrier 11, thereby improving the consistency of the orientation of the pressing surfaces 121 on the multiple press assemblies 12, which is beneficial for the cooperation between the press assemblies 12 and the bearing surface 111.

[0077] More specifically, the press assembly 12 includes a first end 123 and a second end 124, and the second end 124 of the first press is movably connected to the first end 123 of the second press. Such an arrangement enables the multiple press assemblies 12 to be sequentially connected to the bearing surfaces 111 on the carrier 11 one by one after being unfolded. In addition, the above arrangement enables the multiple press assemblies 12 to be adapted to the multiple bearing surfaces 111 that are not on the same plane after being unfolded, so as to facilitate the multiple press assemblies 12 to be able to match the multiple bearing surfaces 111 on the prismatic carrier 11.

[0078] In the present application, the movable connection method between the first press and the second press can be: chain connection, rope connection, hinge connection, hinge connection, tape connection, etc., as long as the second end 124 of the first press and the first end 123 of the second press can be movably connected, and this application does not impose any restrictions.

[0079] In this embodiment, the carrier 11 includes a first state and a second state. When the carrier 11 is in the first state, at least one bearing surface 111 is arranged in parallel with the pressing surface 121. In this way, the pressing surface 121 can cooperate with a bearing surface 111 to fix the battery cell 300. When the carrier 11 is in the second state, the carrier 11 is in a rotating state so that the bearing surfaces 111 are switched. In this way, the carrier 11 in the rotating state also cooperates with multiple press assemblies 12 to unfold, so that the multiple press assemblies 12 can unfold in sequence and cooperate with the bearing surface 111 to fix the battery cell 300.

[0080] like Fig. 9 As shown, as an embodiment, the present application also discloses a processing method for a battery cell 300 suitable for stacking a plurality of presser assemblies 12, the processing method comprising the following steps:

[0081] S1: The conductive connecting member 200 is wound on the carrying surface 111 of the carrier 11;

[0082] S2: The battery cell 300 is placed on the carrying surface 111 of the carrier 11;

[0083] S3: the carrier 11 rotates so that the carrying surface 111 on which the battery cell 300 is placed is located below the multiple stacked press assemblies 12;

[0084] S4: The lowermost pressing tool assembly 12 moves downward to act on the battery cell 300, so that the battery cell 300 is fixed on the carrying surface 111, and the battery cell 300 can contact the conductive connecting member 200 on the carrying surface 111;

[0085] S5: After one battery cell 300 is fixed on one carrying surface 111 by a press assembly 12 , another battery cell 300 is placed on another carrying surface 111 , and the other carrying surface 111 is disposed adjacent to the one carrying surface 111 ;

[0086] S6: the carrier 11 rotates so that the other bearing surface 111 is located below the other pressing tool assembly 12, and the other pressing tool assembly 12 is movably connected to the one pressing tool assembly 12;

[0087] S7 : Another pressing tool assembly 12 moves downward to act on another battery cell 300 , so that the other battery cell 300 is fixed on another carrying surface 111 , and the other battery cell 300 contacts the conductive connecting member 200 on the other carrying surface 111 .

[0088] In step S3 , the carrier 11 rotates to switch the carrier 11 between the first state and the second state, so that the press assembly 12 can cooperate with the carrying surfaces 111 at different positions and fix the corresponding battery cells 300 .

[0089] In step S4, the bottom press assembly 12 acts on the battery cell 300 through magnetic connection or adsorption connection. Through the above steps, the pressing surface 121 on the press assembly 12 can cooperate with the bearing surface 111 to press and contact the battery cell 300 and the conductive connector 200.

[0090] In step S5 , the plurality of press assemblies 12 can continuously act on the battery cells 300 on different carrying surfaces 111 , so that the plurality of press assemblies 12 can continuously fix the battery cells 300 on different carrying surfaces 111 , thereby improving the fixing efficiency of the battery cells 300 .

[0091] In step S6 , the carrier 11 is in the first state after the carrying surface 111 switches from the second state, so that the other carrying surface 111 can be parallel to the pressing surface 121 of the other pressing tool assembly 12 .

[0092] In step S7, another presser assembly 12 acts on another battery cell 300 through magnetic connection or adsorption connection. Through the above steps, the pressing surface 121 on another presser assembly 12 can cooperate with another bearing surface 111 to press and contact another battery cell 300 and the conductive connector 200.

[0093] In the process of one press assembly 12 or the other press assembly 12 moving downward, one of the press assembly 12 and the other press assembly 12 is turned over. This arrangement allows the pressing surfaces 121 on the one press assembly 12 and the other press assembly 12 to face the same direction after unfolding. In the present application, the pressing surfaces 121 of the one press assembly 12 and the other press assembly 12 are arranged toward the carrier 11 after unfolding.

[0094] like Fig.10 As shown, as another embodiment, the present application also discloses a battery cell processing device 100, which includes a carrier 11 and a plurality of presser assemblies 12. The structure of the carrier 11 has been described above and will not be repeated here. The carrier 11 also has a rotational degree of freedom, and a plurality of bearing surfaces 111 are provided, and the plurality of bearing surfaces 111 are distributed on the carrier 11 along the rotation direction of the carrier 11.

[0095] Specifically, two adjacent press assemblies 12 are movably connected, and a plurality of press assemblies 12 are distributed along the rotation direction of the carrier 11 and are arranged around the carrier 11. Among them, a plurality of press assemblies 12 are configured to be able to move synchronously, and each press assembly 12 is configured to be able to move to a bearing surface 111, and each press assembly 12 can make a battery cell 300 contact with the conductive connector 200 on the corresponding bearing surface 111. With such a configuration, a plurality of press assemblies 12 can be moved simultaneously, and each press assembly 12 can press a battery cell 300, thereby improving the pressing efficiency of the battery cell 300 and the conductive connector 200. It should be noted that the manner of the movable connection between the plurality of press assemblies 12 has been described above and will not be repeated here.

[0096] More specifically, the plurality of press assemblies 12 are at least partially located above the carrier 11, the plurality of press assemblies 12 are configured to be able to move downward synchronously, and each press assembly 12 is configured to be able to move onto a carrying surface 111. In this way, each press assembly 12 can press and contact the battery cell 300 on a carrying surface 111 with the conductive connector 200, thereby improving the working efficiency of the processing device 100.

[0097] It should be noted that the present application does not impose any restrictions on the location and movement direction of the hold-down assembly 12 , and it is only necessary that each hold-down assembly 12 can be moved to a bearing surface 111 .

[0098] As an optional implementation, the press assembly 12 includes a first end 123 and a second end 124, and two adjacent press assemblies 12 are defined as a first press and a second press, and the second end 124 of the first press is movably connected to the first end 123 of the second press. This arrangement allows the pressing surfaces 121 of the first press and the second press to face the same direction. In the present application, the pressing surfaces 121 of the first press and the second press are both arranged toward the carrier 11.

[0099] As an optional implementation, the carrying surface 111 is also provided with adsorption holes for adsorbing the battery cell 300. Negative pressure can be formed in the adsorption hole so that the carrying surface 111 can adsorb and connect the battery cell 300 through the adsorption hole. Such a configuration can prevent the battery cell 300 from falling off the carrying surface 111, thereby improving the connection stability of the battery cell 300 on the carrying surface 111. It should be noted that the adsorption holes are only used to prevent the battery cell 300 from falling off the carrying surface 111, that is, the adsorption holes do not need to be used for the contact between the battery cell 300 and the conductive connector 200. Therefore, the number of adsorption holes is small, which is conducive to simplifying the structure of the carrier 11, and further facilitates the processing and maintenance of the carrier 11.

[0100] As an optional implementation, the structure of the press assembly 12 has been described above and will not be repeated here. The carrier 11 includes a first state and a second state. When the carrier 11 is in the first state, each pressing surface 121 corresponds to a bearing surface 111. With such a configuration, the pressing surface 121 of each press assembly 12 can cooperate with a bearing surface 111 to fix the battery cell 300. When the carrier 11 is in the second state, the carrier 11 is in a rotating state so that the bearing surfaces 111 can be switched. With such a configuration, different bearing surfaces 111 on the carrier 11 can continuously provide battery cells 300 and cooperate with the press assembly 12 to fix the battery cells 300.

[0101] like Fig.11 As shown, as an embodiment, the present application provides a processing method for a battery cell 300 having a plurality of presser assemblies 12 that are suitable for synchronous movement, and the processing method comprises the following steps:

[0102] S1: The conductive connecting member 200 is wound on the carrying surface 111 of the carrier 11;

[0103] S2: placing a plurality of battery cells 300 on corresponding carrying surfaces 111 of the carrier 11;

[0104] S3: A plurality of pressing tool assemblies 12 distributed along the rotation direction of the carrier 11 and arranged around the carrier 11 are respectively moved to corresponding carrying surfaces 111;

[0105] S4: Each pressing tool assembly 12 acts on a battery cell 300 to fix each battery cell 300 on a corresponding carrying surface 111 , and enables each battery cell 300 to contact the conductive connector 200 on the corresponding carrying surface 111 .

[0106] In step S2, each battery cell 300 can be adsorbed on a corresponding carrying surface 111 by the negative pressure generated by the adsorption hole. Through the above steps, the connection stability between the battery cell 300 and the carrying surface 111 can be improved to prevent the battery cell 300 from falling off the carrier 11. It can be understood that the carrying surface 111 may not be provided with adsorption holes, as long as the obtuse angle between two adjacent carrying surfaces is large, the battery cell 300 will not fall off the carrier 11 during the rotation of the carrier 11.

[0107] It should be noted that the adsorption holes are only used to prevent the battery cells 300 from falling off the carrier 11 , so the number of the adsorption holes is relatively small, thereby reducing the number of adsorption pipes that cooperate with the adsorption holes, which is beneficial to simplifying the structure of the carrier 11 .

[0108] In step S3 , a plurality of presser assemblies 12 can cooperate with the carrying surfaces 111 at different positions and fix the corresponding battery cells 300 .

[0109] In step S4, the press assembly 12 is connected to the carrying surface 111 by magnetic connection or adsorption. Through the above steps, the pressing surface 121 on the press assembly 12 can cooperate with the carrying surface 111 to press and contact the battery cell 300 and the conductive connector 200.

[0110] In the present application, the area where the multiple carrying surfaces 111 on the carrier 11 where the battery cells 300 are fixed is defined as the first area, and the area where the multiple carrying surfaces 111 on the carrier 11 where the battery cells 300 are not fixed is defined as the second area. Through the above arrangement, the battery cells 300 can continue to be arranged in the second area, so as to improve the processing efficiency of the processing device 100.

[0111] In the present application, a plurality of press assemblies 12 for fixing battery cells 300 are defined as a press assembly, a plurality of press assemblies 12 that have fixed battery cells 300 are defined as a first press assembly, and a plurality of press assemblies 12 that have not fixed battery cells 300 are defined as a second press assembly.

[0112] At this time, the processing method also includes:

[0113] S5: the carrier 11 rotates, and a plurality of battery cells 300 are placed on the corresponding carrying surfaces 111 in the second area;

[0114] S6: The plurality of press components 12 of the second press assembly are respectively moved to the corresponding carrying surfaces 111 on the second region to fix the corresponding battery cells 300 , so that the battery cells 300 on the corresponding carrying surfaces 111 on the second region are in contact with the conductive connectors 200 .

[0115] Specifically, the carrier 11 rotates to switch the rotating carrier 11 between the first state and the second state, so that the press assembly 12 can cooperate with the carrying surface 111 on the second area and fix the corresponding battery cell 300, thereby improving the fixing efficiency of the processing device 100 for the battery cell 300.

[0116] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
