[0066] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0067] The battery structure generally includes a box and a battery cell. The battery cell is placed in the box, so that the box provides a storage space for the battery cell and provides good protection for the battery cell.

[0068] A battery cell is the smallest unit that makes up a battery. According to the different structures and shapes, battery cells can be divided into square battery cells and cylindrical battery cells. Among them, the structure of the cylindrical battery cell is cylindrical. Due to its special shape, it is often difficult to operate during the assembly process.

[0069] In the related art, cylindrical battery cells usually need to be loaded by grabbing. If the grabbing process is not well controlled, the structure of the cylindrical battery cells may be easily damaged. In addition, cylindrical battery cells are inspected in batches. During the inspection of a batch of cylindrical battery cells, the loading and unloading of the cylindrical battery cells have to be stopped, resulting in the loading and unloading of the cylindrical battery cells often having to wait for the inspection process, affecting the overall assembly efficiency of the cylindrical battery cells.

[0070] Based on the above considerations, in order to solve the problem of low efficiency in the assembly process of cylindrical battery cells, one or more embodiments of the present application provide an installation device, which designs a rotating unit, and allows a part of the rotating unit to remain stationary at the inspection station to facilitate inspection, and the other part of the rotating unit can rotate and receive the cylindrical battery cells conveyed by the loading unit from the loading end; in this way, while this part of the rotating unit remains stationary, the other part of the rotating unit is still rotating to receive the cylindrical battery cells conveyed by the loading unit as a new batch of cylindrical battery cells to be inspected; while conducting the inspection, the loading unit can still load the materials at a uniform speed without delaying the loading rhythm of the loading unit, thus facilitating the subsequent processes for inspection and assembly, and making the overall assembly efficiency high.

[0071] See also Figure 1 as well as Figure 2 As shown, the first aspect of the present application provides an installation device, which is used for the boxing and grouping of cylindrical battery cells 900, and the installation device includes: a loading unit 100, a rotating unit 200 and a detection unit 300. Among them, the loading unit 100 has a loading end 100a; the rotating unit 200 is rotatable around a first direction X; the rotating unit 200 has a detection station 200a. The detection unit 300 is arranged on the detection station 200a, and is used to detect the state of the cylindrical battery cell 900.

[0072] When a part of the rotating unit 200 remains stationary at the inspection station 200 a , another part of the rotating unit 200 can rotate and receive the cylindrical battery cell 900 conveyed by the loading unit 100 from the loading end 100 a .

[0073] The loading unit 100 is arranged upstream of the rotating unit 200 along the conveying direction of the cylindrical battery cells 900. The loading unit 100 is used to temporarily store the cylindrical battery cells 900 and can transfer multiple cylindrical battery cells 900 as needed. The loading unit 100 has a loading end 100a; the loading end 100a can be adjacent to the rotating unit 200 to continuously provide the cylindrical battery cells 900 stored in the loading unit 100 to the rotating unit 200, so as to facilitate detection and assembly. In particular, the loading unit 100 can provide horizontally placed cylindrical battery cells 900 as needed.

[0074] The rotating unit 200 can receive the cylindrical battery cells 900 input from the loading end 100a, and can limit and transfer multiple cylindrical battery cells 900; the rotating unit 200 is rotatably arranged around a first direction X, wherein the first direction X can be set as a horizontal direction in a horizontal plane; that is, the rotating unit 200 rotates in a vertical plane along a horizontal direction.

[0075] Specifically, a plurality of first limiting grooves 215 (mentioned below) are provided on the rotating unit 200, and each first limiting groove 215 can accommodate a corresponding cylindrical battery cell 900. That is, a plurality of cylindrical battery cells 900 are limited in each first limiting groove 215 one by one. At the same time, the first loading assembly 10 rotates in a vertical plane around the first direction X, which can drive the cylindrical battery cells 900 in each first limiting groove 215 to rotate synchronously, so as to transfer the cylindrical battery cells 900 from the loading end 100a to the inspection station 20a in batches, so as to facilitate the inspection.

[0076] The detection unit 300 is arranged on the detection station 200a; and can be used to detect the state of the cylindrical battery cell 900 on the detection station 200a.

[0077] When a part of the rotating unit 200 remains stationary at the inspection station 200a, the other part of the rotating unit 200 can rotate and receive the cylindrical battery cell 900 delivered by the loading unit 100 from the loading end 100a; thereby, the loading unit 100 can still load materials at a uniform speed while performing the inspection, thereby not delaying the loading rhythm of the loading unit 100, facilitating the subsequent inspection and assembly processes, and improving the overall assembly efficiency.

[0078] That is to say, a part of the rotating unit 200 can drive a batch of cylindrical cells 900 to rotate around the first direction X, and the detection station 200a is set on the rotation path of the rotating unit 200. When the batch of cylindrical cells 900 moves to align with the detection station 200a, the part of the rotating unit 200 remains stationary and stops rotating, so that the cylindrical cells 900 remain stationary at the detection station 200a; in this way, the cylindrical cells 900 are detected by the detection unit 300 in a stationary state. For example, the detection unit 300 can perform an open circuit voltage test, a current test, etc. on the cylindrical cells 900.

[0079] While this part of the rotating unit 200 remains stationary, another part of the rotating unit 200 can still rotate, so that the other part of the rotating unit 200 can receive cylindrical battery cells 900 from the loading end 100a as a new batch of cylindrical battery cells 900 to be tested; when this part of the rotating unit 200 loads a previous batch of cylindrical battery cells 900 and completes the test at the testing station 200a, the other part of the rotating unit 200 can drive a new batch of cylindrical battery cells 900 to rotate to the testing station 200a again; in this way, the rotating unit 200 can continuously receive cylindrical battery cells 900 at the loading end 100a, and can compensate for the stationary time of the cylindrical battery cells 900 during the test at the testing station 200a, so that the loading unit 100 can continue to load without stopping, effectively improving the assembly efficiency of the cylindrical battery cells 900.

[0080] In some possible embodiments, see Figures 1 to 4As shown; the installation equipment includes a unloading unit 400 having a unloading end 400a, and the rotating unit 200 is adjacent to the unloading end 400a; the detection station 200a is located between the loading end 100a and the unloading end 400a; wherein, the first part of the rotating unit 200 can be stationary at the detection station 200a, the second part of the rotating unit 200 can rotate and receive the cylindrical battery cell 900 from the loading end 100a; the third part of the rotating unit 200 can rotate and transfer the cylindrical battery cell 900 to the unloading end 400a.

[0081] The unloading unit 400 has an unloading end 400a; the unloading end 400a can be adjacent to the rotating unit 200, and the unloading unit 400 is arranged downstream of the rotating unit 200 along the conveying direction of the cylindrical battery cells 900, so as to receive the cylindrical battery cells 900 after inspection. In this way, while the rotating unit 200 drives a batch of cylindrical battery cells 900 for inspection, the rest of the rotating unit 200 can still be unloaded with the unloading unit 400. Such a design will not delay the loading rhythm of the loading unit 100 and the unloading rhythm of the unloading unit 400, and facilitates the execution of subsequent processes, so that the overall assembly efficiency is high.

[0082] Specifically, the first part of the rotating unit 200 can drive a batch of cylindrical cells 900 to rotate around the first direction X. When the batch of cylindrical cells 900 moves to align with the detection station 200a, the first part of the rotating unit 200 remains stationary and stops rotating, so that the batch of cylindrical cells 900 located on the first part of the rotating unit 200 remain stationary at the detection station 200a; the detection unit 300 detects the batch of cylindrical cells 900 in a stationary state. For example, the detection unit 300 can perform an open circuit voltage test, a current test, etc. on the cylindrical cells 900.

[0083] When the first part of the rotating unit 200 remains stationary at the inspection station 200a, the second part of the rotating unit 200 can rotate and receive the cylindrical battery cell 900 from the loading end 100a; the third part of the rotating unit 200 can rotate and transfer the cylindrical battery cell 900 to the lower feeding end 400a; so that while the inspection is being carried out, the loading unit 100 can still load materials to the rotating unit 200, and the unloading unit 400 can still unload materials from the rotating unit 200.

[0084] When the batch of cylindrical cells 900 has completed the inspection at the inspection station 200a, the first part of the rotating unit 200 drives the batch of cylindrical cells 900 to rotate to the unloading end 400a for unloading; at the same time, the second part of the rotating unit 200 drives a new batch of cylindrical cells 900 to rotate from the loading end 100a to the inspection station 200a for inspection; the third part of the rotating unit 200 has completed unloading, and it rotates back from the unloading end 400a to the loading end 100a to receive loading; this process is continuously cycled. The continuous rotation of the rotating unit 200 at the loading end 100a and the unloading end 400a can compensate for the static time of the cylindrical cells 900 during the inspection at the inspection station 200a, so that the loading unit 100 and the unloading unit 400 can continuously load and unload without stopping, effectively improving the assembly efficiency of the cylindrical cells 900.

[0085] In some possible embodiments, see Figures 1 to 12 As shown, the rotating unit 200 includes at least two rotatable rotating components 210. The loading end 100a of the loading unit 100 outputs the cylindrical battery cells 900 along the second direction Z. Each rotating component 210 is configured to be able to rotate unidirectionally from the loading end 100a to the lower feeding end 400a to transfer the cylindrical battery cells 900 from the loading unit 100 to the lower feeding unit 400 in batches; the first direction X and the second direction Z are arranged to intersect.

[0086] The rotating assembly 210 can rotate cyclically from the loading end 100a of the loading unit 100, through the inspection station 200a, to the unloading end 400a of the unloading unit 400, and finally back to the loading end 100a. The continuous rotation of the rotating unit 200 at the loading end 100a and the unloading end 400a can compensate for the static time of the cylindrical battery cell 900 during the inspection at the inspection station 200a, so that the loading unit 100 and the unloading unit 400 can continuously load and unload without stopping, effectively improving the assembly efficiency of the cylindrical battery cell 900.

[0087] The first direction X is arranged to intersect with the second direction Z. In the embodiment of the present application, the first direction X is a horizontal direction, and the second direction Z is a vertical direction.

[0088] The rotating components 210 rotate independently around the first direction X, so that the loading process, the unloading process and the detection process can be completed respectively.

[0089] In some possible embodiments, see Figures 1 to 12 As shown, when one of the rotating components 210 remains stationary at the detection station 200a, the other rotating component 210 can rotate around the first direction X and is adjacent to the loading end 100a and the unloading end 400a respectively.

[0090] When one of the rotating components 210 drives a batch of cylindrical cells 900 to rotate to the inspection station 200a, the batch of cylindrical cells 900 are inspected by the inspection unit 300 in a stationary state. For example, the inspection unit 300 can perform open circuit voltage test and current test on the cylindrical cells 900. Another rotating component 210 can contact the loading end 100a and the unloading end 400a at the same time; that is, it receives the cylindrical cells 900 from the loading end 100a while transferring the cylindrical cells 900 to the unloading end 400a; in this way, the first rotating component 210 drives a batch of cylindrical cells 900 to be inspected, the second loading unit 100 can still load the rotating unit 200, and the unloading unit 400 can still unload the rotating unit 200, which effectively improves the assembly efficiency of the cylindrical cells 900.

[0091] In some possible embodiments, see Figures 1 to 4 As shown, when the rotating component 210 is adjacent to the loading end 100a, the rotating component 210 rotates around the first direction X at a first speed V1; when the rotating component 210 rotates from the loading end 100a to the detection station 200a, the rotating component 210 rotates around the first direction X at a second speed V2; when the rotating component 210 rotates from the detection station 200a to the feeding end 400a, the rotating component 210 rotates around the first direction X at a third speed V3.

[0092] The second speed V2 is equal to the third speed V3 and both are greater than the first speed V1 .

[0093] The rotating assembly 210 will sequentially undergo a loading process, a first transfer process, a detection process, a second transfer process and a unloading process during the rotation process.

[0094] See also Figure 3 and Figure 4 During the loading process: the rotating component 210 loads at the loading end 100a, the rotating component 210 can slowly rotate around the first direction X at a first speed V1, and the loading unit 100 can transmit the cylindrical battery cell 900 at a speed matching therewith, and the first limiting groove 215 on the rotating component 210 can accommodate the cylindrical battery 900 from the loading end 100a one by one, so that the rotating component 210 can continuously receive the cylindrical battery cell 900 input from the loading end 100a during the rotation process.

[0095] During the first transfer process: after the multiple cylindrical cells 900 are loaded at the loading end 100a, the rotating assembly 210 needs to transport the multiple cylindrical cells 900 as a batch to the inspection station 200a and keep it still. The rotating assembly 210 rotates from the loading end 100a to the inspection station 200a. During the rotation process, the rotating assembly 210 rotates around the first direction X at a second speed V2; the second speed V2 is greater than the first speed V1, and the rotating assembly 210 transfers the cylindrical cells 900 on the loading unit 100 to the inspection station 200a in batches at a faster speed.

[0096] During the inspection process: the cylindrical battery cell 900 on the rotating assembly 210 remains stationary at the inspection station 200a and is inspected by the inspection unit 300. The inspection unit 300 can perform open circuit voltage test, current test, etc. on the cylindrical battery cell 900.

[0097] In the second transfer process: after the cylindrical battery cell 900 on the rotating assembly 210 has been inspected at the inspection station 200a, the rotating assembly 210 needs to transport the cylindrical battery cell 900 to the unloading end 400a of the unloading unit 400. In the process of the rotating assembly 210 rotating from the inspection station 200a to the unloading end 400a, the rotating assembly 210 rotates rapidly around the first direction X at a third speed V3. The third speed V3 is greater than the first speed V1, and the rotating assembly 210 transfers the cylindrical battery cell 900 on the rotating assembly 210 from the inspection station 200a to the unloading end 400a at a faster speed.

[0098] During the unloading process: the rotating assembly 210 is adjacent to the unloading end 400a. When the rotating assembly 210 is unloading at the unloading end 400a, the rotating assembly 210 can rotate around the first direction X at the same first speed V1 as when loading, and the unloading unit 400 can receive the cylindrical battery cell 900 at a speed matching the speed, so that the rotating assembly 210 transfers the cylindrical battery cell 900 that has been inspected to the unloading end 400a. The loading speed is consistent with the unloading speed, so that the entire installation equipment can continuously load and unload without waiting, effectively improving the assembly efficiency of the cylindrical battery cell 900.

[0099] The rotating assembly 210 rotates at a relatively slow speed (i.e., the first speed V1) during the loading process at the loading end 100a and during the unloading process at the unloading end 400a to realize the loading and unloading of the cylindrical battery cell 900. Since the cylindrical battery cell 900 needs to remain stationary at the detection station 200a during the detection process, the rotating assembly 210 transfers the cylindrical battery cell 900 from the loading end 100a to the detection station 200a at a relatively fast speed (i.e., the second speed V2) during the first transfer process; and the rotating assembly 210 transfers the cylindrical battery cell 900 from the detection station 200a to the unloading end 400a at a relatively fast speed (i.e., the third speed V3) during the second transfer process.

[0100] By setting the speed difference between the first speed V1 and the second speed V2 and the third speed V3, the time that the cylindrical battery cell 900 is stationary at the inspection station 200a can be compensated; that is, the speed difference of the rotating assembly 210 at different stages can compensate for the time that the cylindrical battery cell 900 is stationary at the inspection station 200a. In this way, the loading unit 100 and the unloading unit 400 do not need to be stopped, and continuous loading and unloading can be achieved, which can improve the assembly efficiency of the cylindrical battery cell 900.

[0101] It is understandable that the loading process, the first transfer process, the detection process, the second transfer process, and the unloading process can be completed by two, three, four, or more rotating components 210. The number of rotating components 210 can be adjusted according to actual use requirements. For ease of understanding, the following description is based on an example in which the rotating unit 200 includes two rotating components 210.

[0102] In some possible embodiments, see Figures 1 to 4 ,as well as Figures 9 to 12 As shown, each rotating assembly 210 includes a driving member 211 , a rotating shaft 212 and two coplanarly arranged sector disks 214 ; the rotating shaft 212 is connected at the intersection of the two sector disks 214 and extends along the first direction X, and the driving member 211 is drivingly connected to the rotating shaft 212 .

[0103] A plurality of first limiting grooves 215 are correspondingly formed on each sector disk 214 to accommodate the cylindrical battery cells 900 one by one. Each sector disk 214 is configured to be able to rotate around the first direction X, and circulate through the loading end 100a, the inspection station 200a and the unloading end 400a in sequence to transfer the cylindrical battery cells 900 from the loading unit 100 to the unloading unit 400 in batches.

[0104] Specifically, the driving member 211 may be a driving motor or a stepping motor, the rotating shaft 212 is connected to the intersection of the two sector disks 214 and extends along the first direction X, and the rotating shaft 212 is drivingly connected to the output shaft of the driving member 211. When the driving motor is started, the rotating shaft 212 and the sector disk 214 are driven to rotate.

[0105] In a rotating assembly 210, two sector disks 214 are arranged in the same plane, which means that the two sector disks 214 are in the same plane and the center ends are connected as one. The two sector disks 214 are usually arranged symmetrically about the origin of the intersection of the two. Fig.12 As shown, along the projection in the first direction X, the inspection station 200 a is located directly above the rotating shaft 212 , and the loading end 100 a and the unloading end 400 a are located at two side areas of the rotating shaft 212 , respectively.

[0106] A plurality of first limiting grooves 215 are correspondingly formed on each sector disk 214 to accommodate the cylindrical battery cells 900 in a one-to-one correspondence.

[0107] It should be noted that the fan-shaped disk 214 has a certain angle range, and the cylindrical battery cell 900 is transferred from the feeding end 100a to the first first limiting groove 215 of the fan-shaped disk 214, until the feeding end 100a transfers the cylindrical battery cell 900 to the last first limiting groove 215 of the fan-shaped disk 214. In this whole process, the fan-shaped disk 214 is considered to be adjacent to the feeding end 100a. The fan-shaped disk 214 and the unloading end 400a are also the same, and will not be repeated here.

[0108] During the loading process, when the fan-shaped disk 214 of one of the rotating components 210 drives the cylindrical battery cell 900 to be transferred to the inspection station 200a, the fan-shaped disk 214 of the other rotating component 210 is immediately adjacent to the loading end 100a of the loading unit 100 to facilitate the uninterrupted transfer of the cylindrical battery cell 900 from the loading unit 100 to the rotating unit 200.

[0109] Similarly, during the unloading process, when all the cylindrical cells 900 on the fan-shaped disk 214 of one rotating assembly 210 are transferred to the unloading unit 400, the fan-shaped disk 214 of another rotating assembly 210 is immediately adjacent to the unloading end of the unloading unit 400, so as to uninterruptedly transfer the cylindrical cells 900 to the unloading unit 400. The fan-shaped disk 214 of each rotating assembly 210 is configured to be unidirectionally rotatable around the first direction X, so as to prevent interference between the rotating assemblies 210 during the transfer process.

[0110] During the inspection process, the cylindrical cells 900 on the sector disk 214 of one rotating assembly 210 remain stationary at the inspection station 200a, and the inspection unit 300 inspects them. For example, the inspection unit 300 can perform an open circuit voltage test, a current test, etc. on the cylindrical cells 900. After the inspection is completed, the rotating assembly 210 continues to rotate to transfer the inspected cylindrical cells 900 to the lower feed end 400a; the sector disk 214 of the other rotating assembly 210 drives the uninspected cylindrical cells 900 to the inspection station 200a, and the next batch of inspections can be performed.

[0111] Through the above-mentioned structural arrangement, each fan-shaped disk 214 circulates through the loading end 100a, the inspection station 200a and the unloading end 400a in turn to transfer the cylindrical battery cells 900 from the loading unit 100 to the unloading unit 400 in batches; thereby, the loading process, the unloading process and the inspection process can be completed respectively; and the loading unit 100 and the unloading unit 400 can continuously load and unload without stopping, thereby effectively improving the assembly efficiency of the cylindrical battery cells 900.

[0112] In some possible embodiments, see Figures 1 to 12 As shown, one of the rotating components 210 can remain stationary, and the sector disk 214 of the rotating component 210 is located at the detection station 200a. The other rotating component 210 can rotate around the first direction X, and one of the sector disks 214 is adjacent to the feeding end 100a, and the other sector disk 214 is adjacent to the feeding end 100a.

[0113] For the convenience of description, the first rotating component 210 is defined as the first rotating component 210a, and the two fan-shaped disks 214 included therein are respectively the first fan-shaped disk 2141 and the second fan-shaped disk 2142; the second rotating component 210 is defined as the second rotating component 210b, and the two fan-shaped disks 214 included therein are respectively the third fan-shaped disk 2143 and the fourth fan-shaped disk 2144.

[0114] See also Figures 1 to 11 , and specifically combined Fig.12 As shown; the first sector disk 2141 of the first rotating assembly 210a drives a batch of cylindrical cells 900 to rotate to the detection station 200a, and the batch of cylindrical cells 900 are detected by the detection unit 300 in a stationary state. For example, the detection unit 300 can perform an open circuit voltage test, a current test, etc. on the cylindrical cells 900. The second sector disk 2142 of the first rotating assembly 210a is in an unloaded state without cylindrical cells 900, and is located below the rotating shaft 212, waiting to be rotated back to the loading end 100a after the detection is completed. In some embodiments, a corresponding cleaning device can be provided below the rotating shaft 212 for cleaning and maintaining the unloaded sector disk 214.

[0115] The third sector disk 2143 of the second rotating assembly 210b can be adjacent to the loading end 100a to receive the cylindrical battery cells 900 continuously conveyed by the loading unit 100; the fourth sector disk 2144 of the second rotating assembly 210b can be adjacent to the unloading end 400a to transfer the cylindrical battery cells 900 to the unloading end 400a. In this way, a second rotating assembly 210b can contact the loading end 100a and the unloading end 400a at the same time; that is, it receives the cylindrical battery cells 900 from the loading end 100a while transferring the cylindrical battery cells 900 to the unloading end 400a; in this way, a batch of cylindrical battery cells 900 are driven by the first first rotating assembly 210a for inspection, and the loading unit 100 can still load the second rotating assembly 210b, and the unloading unit 400 can still unload the second rotating assembly 210b, effectively improving the assembly efficiency of the cylindrical battery cells 900.

[0116] The cooperation between the first rotating assembly 210a and the second rotating assembly 210b can realize the installation process of the equipment without stopping.

[0117] The loading process, unloading process and testing process are carried out simultaneously.

[0118] The third sector disk 2143 of the second rotating assembly 210b is used for loading at the loading end 100a, and the fourth sector disk 2144 of the second rotating assembly 210b is used for unloading at the unloading end 400a. The second rotating assembly 210b as a whole can be rotated slowly clockwise around the first direction X at a first speed V1, the loading unit 100 can transmit the cylindrical battery cell 900 at a speed matching the third sector disk 2143, and the unloading unit 400 can receive the cylindrical battery cell 900 at a speed matching the fourth sector disk 2144.

[0119] At the same time, the first sector disk 2141 on the first rotating assembly 210a is stationary at the inspection station 200a and is inspected by the inspection unit 300. The inspection unit 300 can perform open circuit voltage test, current test, etc. on the cylindrical battery cell 900. The second sector disk 2142 of the first rotating assembly 210a is in an unloaded state without the cylindrical battery cell 900, and is located below the rotating shaft 212, waiting to be rotated back to the loading end 100a.

[0120] A second transfer process is performed.

[0121] When a batch of cylindrical cells on the first sector disk 2141 are inspected at the inspection station 200a, the first rotating assembly 210a enters the second transfer process, and the first rotating assembly 210a as a whole can rotate clockwise around the first direction X at a third speed V3 until the first sector disk 2141 is adjacent to the unloading end 400a, and the second sector disk 2142 is adjacent to the loading end 400a;

[0122] A first transfer process is performed.

[0123] When the third sector disk 2143 has finished loading at the loading end 100a, and the fourth sector disk 2144 has finished unloading at the unloading end 400a, the second rotating assembly 210b rotates clockwise around the first direction X at the second speed V2. That is, the third fan-shaped disk 2143 of the second rotating component 210b drives the cylindrical battery cell 900 to leave the loading end 400a and rotate toward the inspection station 200a (at this time, the second fan-shaped disk 2142 of another first rotating component 210a is immediately adjacent to the loading end 100a of the loading unit 100 to restart a new round of loading process), and the fourth fan-shaped disk 2144 of the second rotating component 210b is unloaded. The fourth fan-shaped disk 2144 is in an unloaded state without the cylindrical battery cell 900 loaded, and rotates toward the bottom of the rotating shaft 212 (at this time, the first fan-shaped disk 2141 of another first rotating component 210a is immediately adjacent to the unloading end 400a of the unloading unit 400 to restart a new round of unloading process). The third sector disk 2143 rotates to the detection station 200a, and the second rotating assembly 210b stops, and the cylindrical battery core 900 on the third sector disk 2143 remains stationary to cooperate with the detection unit 300 to perform a new round of detection process).

[0124] The subsequent working process of the first rotating assembly 210a and the second rotating assembly 210b can be continuously cycled as described above. By setting the speed difference between the first speed V1 and the second speed V2 and the third speed V3, the time that the cylindrical battery cell 900 is stationary at the detection station 200a can be compensated. Finally, the loading unit 100 and the unloading unit 400 do not need to be stopped, and continuous loading and unloading can be achieved, which can improve the assembly efficiency of the cylindrical battery cell 900.

[0125] In some possible embodiments, see Figures 1 to 12 As shown, the rotating shafts 212 of all the rotating components 210 extend along the first direction X and are coaxially arranged; projected along the first direction X, the sector disks 214 of all the rotating components 210 are staggered with each other.

[0126] Through the above-mentioned structural setting, the rotating components 210 can rotate independently around the first direction X; thereby, the loading process, the unloading process and the detection process can be completed separately, so that the loading unit 100 and the unloading unit 400 do not need to be stopped, and continuous loading and unloading can be achieved, which can improve the assembly efficiency of the cylindrical battery cell 900.

[0127] It is understandable that, in the present application, the axial direction of the rotating shaft 212 is the first direction X; the first direction X can be set as a horizontal direction in a horizontal plane. The disk surface of the sector disk 214 rotates in a vertical plane.

[0128] In some possible embodiments, see Fig.11 As shown, the sector disk 214 has an arc edge 214a matching its own rotation path, and each first limiting groove 215 is opened on the arc edge 214a.

[0129] In various embodiments of the present application, the sector disk 214 is configured as a sector structure, and the sector disk 214 can be configured as a disc structure smaller than a quarter as required. That is, the center angle of the sector disk 214 should generally be smaller than 90°; in the embodiment of the present application, the center angle of the sector disk 214 can be 30°, 45°, 50°, 60°, or 75°, depending on the design.

[0130] Thus, an arc edge 214 a is formed on the sector disk 214 , and each sector disk 214 rotates around the center of the circle (that is, the center of the rotating shaft 212 ), and the arc edge 214 a coincides with the rotation path of each sector disk 214 .

[0131] A plurality of first limiting grooves 215 are provided on the arc edge 214a of each sector disk 214. During the rotation process, the sector disk 214 of each rotating assembly 210 can receive the cylindrical battery cells 900 continuously conveyed by the loading unit 100, or transfer the cylindrical battery cells 900 in the first limiting grooves 215 to the unloading unit 400.

[0132] The installation device is used to arrange multiple cylindrical cells in a box and assemble them into a battery. When the cylindrical cells are arranged in the box, they are usually placed in a vertical direction. That is, the axial direction of the cylindrical cells is arranged along the vertical direction. Usually, multiple cylindrical cells 900 are placed on the bottom plate of the box and can be arranged in the box in a rectangular array.

[0133] In the related art, cylindrical cells usually need to be loaded by grabbing. If the grabbing process is not well controlled, it is easy to cause damage to the structure of the cylindrical cells. For another example, the shape of the cylindrical cells is not convenient for transportation. Therefore, in order to make the cylindrical cells more stable during transportation, it is usually necessary to equip them with pallets, that is, fix the cylindrical cells on pallets for transportation. However, fixing the cylindrical cells on pallets is not only complicated to operate, but also involves the collection and caching of pallets, which makes the assembly process complicated and affects the overall assembly efficiency of the cylindrical cells.

[0134] In some possible embodiments, see Figures 1 to 4 As shown, the loading unit 100 is used to output the horizontally placed cylindrical battery cells 900 ; the rotating assembly 210 includes a plurality of fixing members 216 ; the fixing members 216 are used to fix the cylindrical battery cells 900 in the corresponding first limiting grooves 215 .

[0135] The loading unit 100 is used to output the horizontally placed cylindrical battery cells 900, so that there is no need to use a tray to fix the cylindrical battery cells 900 during the loading unit 100, the rotating unit 200, and the detection process; this makes the operation simple and reduces the collection and caching processes of the tray, making the assembly process simple, thereby improving the overall assembly efficiency of the cylindrical battery cells.

[0136] Combination Fig.11 As shown, the first limiting groove 215 can be a semi-closed groove with openings at both ends and the top side, and the groove wall of the first limiting groove 215 can support the circumference of the corresponding cylindrical battery core 900 .

[0137] The sector disk 214 of the rotating assembly 210 rotates in a vertical plane around the first direction X, and the fixing member 216 can be used to fix the cylindrical battery cell 900 in the corresponding first limiting groove 215 to prevent the sector disk 214 from loosening when rotating to the lower side.

[0138] In some possible embodiments, the fixing member 216 may be a movable baffle, and the movable baffle cover is disposed on the opening of the corresponding first limiting groove 215 , so as to limit the cylindrical battery cell 900 together.

[0139] In some possible embodiments, the fixing member 216 may be a clamping block, which is disposed in the corresponding first limiting groove 215 , so as to clamp and fix the cylindrical battery cell 900 .

[0140] In some possible embodiments, see Figures 1 to 11 As shown, the fixing member 216 is a negative pressure suction tube.

[0141] Specifically, the rotating assembly 210 includes an air slip ring (not marked) and a negative pressure pump (not marked); the air slip ring is arranged in the center area of ​​the fan-shaped disk 214, one end of the fixing member 216 is located in the corresponding first limiting groove 215, and the other end of the fixing member 216 extends along the radial direction of the fan-shaped disk 214 to the air slip ring and is connected to the negative pressure pump.

[0142] The negative pressure generated by the fixing member 216 adsorbs and fixes the cylindrical battery cell 900 in the corresponding first limiting groove 215, effectively preventing the cylindrical battery cell 900 from being separated from the fan-shaped disk 214; in this way, the cylindrical battery cell 900 can be transferred from the loading unit 100 to the first limiting groove 215 and remain fixed, and the cylindrical battery cell 900 can be inspected by the detection unit 300 in the first limiting groove 215 without relative displacement; when needed, by canceling the negative pressure generated by the fixing member 216, the cylindrical battery cell 900 can be transferred from the first limiting groove 215 to the unloading unit 400.

[0143] In some possible embodiments, see Figures 1 to 5 ,as well as Figure 8As shown, the loading unit 100 includes a loading turntable 110, and the loading turntable 110 includes a bottom plate 111 and a side plate 112. The bottom plate 111 and the side plate 112 together enclose a receiving cavity 113 and an extrusion channel 114 that are interconnected. The cylindrical battery cell 900 is placed vertically on the bottom plate 111. The bottom plate 111 is rotatably arranged around a second direction Z, and the cylindrical battery cell 900 in the receiving cavity 113 is transferred to the extrusion channel 114 by rotation.

[0144] Specifically, the loading unit 100 is located upstream of the rotating unit 200, and the loading turntable 110 can realize the storage and transfer of the cylindrical battery cells 900. Specifically, the bottom plate 111 of the loading turntable 110 is set as a circular structure, and the side plate 112 is surrounded by the outer periphery of the bottom plate 111, and the two are together enclosed to form a circular accommodating cavity 113 and an extrusion channel 114 connected to the accommodating cavity 113.

[0145] The width of the extrusion channel 114 matches the diameter of the cylindrical battery cell 900 ; that is, the width of the extrusion channel 114 should be exactly equal to or slightly larger than the diameter of the cylindrical battery cell 900 ; in this way, the cylindrical battery cells 900 can be arranged in sequence in the extrusion channel 114 .

[0146] Combination Figure 1 , Figure 4 and Figure 8 As shown, a plurality of cylindrical cells 900 are placed in the accommodating cavity 113 and are placed in a vertical state, that is, the bottom surface of the cylindrical cell 900 is supported on the bottom plate 111. The bottom plate 111 rotates in a horizontal plane, thereby driving the cylindrical cells 900 placed thereon to move synchronously. In this process, the cylindrical cells 900 can be transferred to the extrusion channel 114 in sequence, so that the cylindrical cells 900 move in the extrusion channel 114 toward the feeding end 100a.

[0147] Combination Figure 8 and Fig.12 As shown, the cylindrical battery cell 900 on the first sector disk 2141 of the first rotating assembly 210a needs to remain stationary when it is in the detection station 200a for testing the open circuit voltage and other contents. At this time, the second rotating assembly 210b and the loading turntable 110 still maintain the loading action, so that repeated shutdown and restart can be avoided, and continuous loading can be achieved, reducing the time for the cylindrical battery cell 900 to be smoothly transferred to the extrusion channel 114, which improves the assembly efficiency on the one hand, and reduces the wear between the bottom surface of the cylindrical battery cell 900 and the bottom plate 111 on the other hand.

[0148] Therefore, the loading process and the detection process are staggered by different rotating components 210; and the different speeds of the rotating components 210 in the entire production process and the speed difference between the first speed V1 and the second speed V2 are utilized to compensate for the time that the cylindrical battery cell 900 is stationary at the detection station 200a; in this way, the loading unit 100 does not need to be shut down, and continuous loading and unloading can be achieved, which can improve the assembly efficiency of the cylindrical battery cell 900 and protect the structure of the cylindrical battery cell 900.

[0149] Through the above structure, the cylindrical battery cells 900 can be transferred while maintaining a vertical state, and are arranged in sequence in the extrusion channel 114 and move toward the feeding end 100 a, and are finally transferred one by one to the first limiting grooves 215 of the sector disk 114 .

[0150] In some possible embodiments, see Figures 1 to 5 ,as well as Figure 8 As shown, the loading turntable 110 also includes a lever 115 , one end of which is rotatably connected to the center of the bottom plate 111 to drive the cylindrical battery cell 900 in the middle of the accommodating cavity 113 to move toward the side plate 112 .

[0151] Specifically, one end of the lever 115 is rotatably disposed at the center of the bottom plate 111 , and the other end can move the cylindrical battery cell 900 to the edge close to the side plate 112 , so that the cylindrical battery cell 900 can be better transferred to the extrusion channel 114 during the rotation process.

[0152] By setting the lever 115, the cylindrical battery cell 900 can be more concentratedly arranged at the edge of the accommodating cavity 113 close to the side plate 112, so that the cylindrical battery cell 900 can be more smoothly transferred from the accommodating cavity 113 to the extrusion channel 114, and finally under the action of the extrusion force, the cylindrical battery cell 900 moves toward the feeding end 100a.

[0153] In some possible embodiments, see Figures 1 to 5 ,as well as Figure 8 As shown, the loading unit 100 includes a first conveying member 116 and a first conveying baffle 117. The first conveying member 116 and the first conveying baffle 117 are spaced to form a first conveying channel 118. One end of the first conveying channel 118 is connected to the extrusion channel 114, and the other end is connected to the loading end 100a; wherein the first conveying member 116 is used to separate each two adjacent cylindrical battery cells 900 and convey them to the upper feeding end 100a; the first conveying baffle 117 is used to guide the cylindrical battery cells 900 from a vertical state to a horizontal state one by one.

[0154] Specifically, the first conveying member 116 can drive the cylindrical battery cells 900 to move from the extrusion channel 114 to the conveying channel 118, and in the process of the cylindrical battery cells 900 moving to the conveying channel 118, each two adjacent cylindrical battery cells 900 are separated so that each cylindrical battery cell 900 is separated by a certain distance, so as to facilitate the one-to-one transfer of the cylindrical battery cells 900 to each first limiting groove 215.

[0155] The first conveying baffle 117 can be an arc-shaped plate spirally wrapped around the circumference of the first conveying member 116; the first conveying baffle 117 cooperates with the first conveying member 116, so that when the cylindrical battery cells 900 move to the conveying channel 118, the cylindrical battery cells 900 lean on the first conveying baffle 117, thereby guiding the cylindrical battery cells 900 from a vertical state to a horizontal state one by one.

[0156] In this way, through the above structure, the cylindrical battery cell 900 can be smoothly transferred in the extrusion channel 114, and finally each cylindrical battery cell 900 can be accommodated in the first limiting groove 215 in a horizontal state; thus, there is no need to use a tray to fix the cylindrical battery cell 900 during the rotation unit 200 and the detection process; and it makes it easier to grab the cylindrical battery cell 900, and reduces the collection and caching process of the tray, so that the assembly process is simple, thereby improving the overall assembly efficiency of the cylindrical battery cell.

[0157] In some possible embodiments, see Figures 1 to 5 ,as well as Figure 8 As shown, the first conveying member 116 is a screw member. The first conveying member 116 includes a first screw 119 and a first spiral ridge 120. The first screw 119 is rotatably arranged. The first spiral ridge 120 spirals along the axial direction of the first screw 119 and protrudes from the outer periphery of the first screw 119 to form a plurality of first spiral grooves 125 for accommodating the cylindrical battery cells 900 in a one-to-one correspondence.

[0158] Specifically, the first screw 119 extends along the third direction Y and can rotate around its own axis. The first spiral ridge 120 spirals along the axial direction of the first screw 119 and protrudes from the outer periphery of the first screw 119 , thereby defining a plurality of first spiral grooves 125 arranged in sequence along the axial direction of the first screw 119 .

[0159] When the first screw 119 rotates around its own axis, the first spiral ridge 120 rotates synchronously with the first screw 119, so that a certain distance is maintained between each two adjacent cylindrical battery cells 900, and under the guidance of the first conveying baffle 117, the cylindrical battery cells 900 are guided one by one from a vertical state to a horizontal state. In this way, the horizontal cylindrical battery cells 900 can be better transferred from the first conveying channel 118 to the loading end 100a and provided to the rotating unit 100, so that each cylindrical battery cell 900 can be accommodated one by one in each first limiting groove 215.

[0160] In some possible embodiments, see Figures 1 to 5 ,as well as Figure 8 As shown, the loading unit 100 includes a first conveyor belt 121 , a first conveying gear 122 and a first arc-shaped baffle 123 .

[0161] One end of the first conveyor belt 121 is connected to the first conveying channel 118, and the other end extends along the third direction Y until it is connected to one end of the first arc-shaped baffle 123. The first conveying gear 122 is rotatably mounted above the first arc-shaped baffle 123 around the first direction X. A plurality of second limiting grooves 124 are provided on the peripheral side surface of the first conveying gear 122. The curvature of the first arc-shaped baffle 123 is consistent with the curvature of the peripheral side surface of the first conveying gear 122, and is used to limit each cylindrical battery cell 900 in the corresponding second limiting groove 124. The feeding end 100a is the other end of the first arc-shaped baffle 123 away from the first conveyor belt 121. The feeding end 100a extends along the second direction Z and is tangent to the rotating unit 200. The first direction X, the second direction Z and the third direction Y are arranged to intersect each other.

[0162] The first conveyor belt 121 is arranged upstream of the first arc-shaped baffle 123, and can transfer the horizontally placed cylindrical battery cells 900 to the first arc-shaped baffle 123 along the third direction Y. The first conveyor belt 121 has a plurality of fourth limiting grooves (not marked) for accommodating the horizontally placed cylindrical battery cells 900. The first conveyor belt 121 can transfer the horizontal cylindrical battery cells 900 from the first conveying channel 118 to the first arc-shaped baffle 123. Under the limitation of the first arc-shaped baffle 123, the horizontal cylindrical battery cells 900 are embedded in the second limiting grooves 124 on the first conveying gear 122, and move along the third direction Y and the second direction Z as the first conveying gear 122 rotates, so as to reach a suitable position for convenient loading with the rotating unit 200.

[0163] The curvature of the first arc-shaped baffle plate 123 is consistent with the curvature of the peripheral side surface of the first conveying tooth 122, so that the first arc-shaped baffle plate 123 can be bent and extended along the arc edge of the first conveying tooth 122; furthermore, the first arc-shaped baffle plate 123 can limit the cylindrical battery cells 900 in the second limiting groove 124, so that the cylindrical battery cells 900 in the second limiting groove 124 can be smoothly transferred from the first conveyor belt 121 to the loading end 100a of the first arc-shaped baffle plate 123 away from the first conveyor belt 121; the first arc-shaped baffle plate 123 no longer limits the cylindrical battery cells 900 in the second limiting groove 124 at this point, so that the cylindrical battery cells 900 are transferred from the second limiting groove 124 to the first limiting groove 215 of the rotating unit 200 to complete the loading.

[0164] Through the above structure, it is possible to change the vertically placed cylindrical battery cell 900 to a horizontal position and successfully complete the loading, so as to facilitate moving the cylindrical battery cell 900 to a subsequent process.

[0165] In the embodiment of the present application, the second limiting groove 124 may be a semi-closed groove with openings at both ends and the top side, and the groove wall of the second limiting groove 124 can support the circumference of the corresponding cylindrical battery cell 900 .

[0166] In various embodiments of the present application, the first direction X, the second direction Z, and the third direction Y are arranged to intersect each other. Specifically, the first direction X can be set as a horizontal direction in a horizontal plane; the third direction Y can be set as another horizontal direction in the horizontal plane; and the second direction Z can be set as a vertical direction.

[0167] In some possible embodiments, see Figures 1 to 4 , Fig. 9 as well as Fig.10 As shown, the detection unit 300 includes a fixed probe 310 and a pressing probe 320 respectively arranged on opposite sides of the detection station 200a along the first direction X. The pressing probe 320 is movably arranged along the first direction X and is used to press the cylindrical battery cell 900 against the corresponding fixed probe 310 to detect the state of the cylindrical battery cell 900.

[0168] Specifically, combined Fig.10In the orientation shown, the fixed probe 310 and the pressing probe 320 are respectively arranged on the right side and the left side of the detection station 200a. When the cylindrical battery cells 900 are transferred to the detection station 200a, the cylindrical battery cells 900 are placed horizontally in the first limiting groove 215 one by one. At this time, the pressing probe 320 is moved to the right to press against the top of the cylindrical battery cell 900, and the fixed probe 310 is then pressed against the bottom of the cylindrical battery cell 900, and the fixed probe 310 and the pressing probe 320 are respectively connected to the positive and negative poles of the external detection instrument to detect the open circuit voltage of the cylindrical battery cell 900, that is, the OCV detection of the cylindrical battery cell 900 is realized.

[0169] It is understandable that since the cylindrical battery cell 900 is placed horizontally, there is no need to set up a pallet when conducting inspection at this workstation. On the one hand, this avoids the wear of the pallet on the bottom of the cylindrical battery cell 900, and on the other hand, it makes the inspection operation simpler and reduces the collection and caching process of the pallet, does not affect the subsequent transportation of the cylindrical battery cell 900, changes the subsequent overall production rhythm, and thus improves the overall assembly efficiency of the cylindrical battery cell.

[0170] In some possible embodiments, see Figures 1 to 4 , Fig. 9 as well as Fig.10 As shown, the detection unit 300 includes a cleaning nozzle 330 , which is disposed above the detection station 200 a and radially aligned with the area between the fixed probe 310 and the pressing probe 320 .

[0171] The cleaning nozzle 330 may be a structure capable of plasma cleaning the outer surface of the cylindrical battery cell 900. The cleaning nozzle 330 is radially aligned with the area between the fixed probe 310 and the pressing probe 320; when the rotating assembly 210 rotates to the detection station 200a and remains stationary, the fixed probe 310 and the pressing probe 320 can approach to detect the cylindrical battery cell 900, and after the detection is completed, the cleaning nozzle 330 can clean the outer surface of the cylindrical battery cell 900 exposed on the first limiting groove 215; keep the outer surface of the cylindrical battery cell 900 clean, so as to facilitate the subsequent assembly of the cylindrical battery cell 900 into the box.

[0172] It should be noted that the fixed probe 310 and the pressure probe 320 perform a detection step, and the cleaning nozzle 330 performs a cleaning step. Usually, the detection step can be performed first and then the cleaning step, or the cleaning step can be performed first and then the detection step, or both can be performed at the same time, and the embodiments of the present application are not limited to this.

[0173] In some possible embodiments, see Figures 3 to 7 As shown, the unloading unit 400 includes a second conveyor belt 410 , a second conveying gear 420 and a second arc-shaped baffle 430 .

[0174] One end of the second conveyor belt 410 extends along the third direction Y until it is connected to one end of the second arc-shaped baffle 430; the second conveyor gear 420 is rotatably mounted above the second arc-shaped baffle 430 around the first direction X, and a plurality of third limiting grooves 421 are provided on the peripheral side surface of the second conveyor gear 420. The curvature of the second arc-shaped baffle 430 is consistent with the curvature of the peripheral side surface of the second conveyor gear 420, and is used to limit each cylindrical battery cell 900 in the corresponding third limiting groove 421. The unloading end 400a is the other end of the second arc-shaped baffle 430 away from the second conveyor belt 410. The unloading end 400a extends along the second direction Z and is tangent to the rotating unit 200. The first direction X, the second direction Z and the third direction Y are arranged to intersect each other.

[0175] One end of the second arc-shaped baffle plate 430 is connected to the second conveyor belt 410, and the end of the second conveyor belt 410 away from the second conveyor belt 410 is a material discharge end 400a. The material discharge end 400a can receive the cylindrical battery cell 900 transferred from the first limiting groove 215 of the rotating unit 200, and then, the horizontal cylindrical battery cell 900 is embedded in the third limiting groove 421 on the second conveying tooth 420 under the guidance of the second arc-shaped baffle plate 430, and the cylindrical battery cell 900 rotates with the second conveying tooth 420 to complete the material discharge.

[0176] The curvature of the second arc-shaped baffle plate 430 is consistent with the curvature of the peripheral side surface of the second conveying tooth 420 , so that the second arc-shaped baffle plate 430 can be bent and extended along the arc edge of the second conveying tooth 420 , and each cylindrical battery cell 900 in the third limiting groove 421 can be limited by the second arc-shaped baffle plate 430 .

[0177] The horizontal cylindrical battery cell 900 moves along the third direction Y and the second direction Z as the first conveying gear 122 rotates, thereby reaching an end of the second arc baffle 430 close to the second conveyor belt 410 .

[0178] The second conveyor belt 410 is disposed downstream of the second arc-shaped baffle plate 430 and can receive the horizontally placed cylindrical battery cells 900 transmitted by the second arc-shaped baffle plate 430 along the third direction Y. The second conveyor belt 410 has a plurality of fifth limiting grooves (not shown) for accommodating the horizontally placed cylindrical battery cells 900. The second conveyor belt 410 can transfer the horizontal cylindrical battery cells 900 from the second arc-shaped baffle plate 430 to a subsequent assembly process.

[0179] Through the above structure, it is possible to receive the horizontally placed cylindrical battery cell 900 and successfully complete the unloading, so as to facilitate moving the cylindrical battery cell 900 to the subsequent process.

[0180] In some possible embodiments, see Figures 3 to 7As shown, the installation device includes a transfer unit 500 , which is configured to transfer the cylindrical battery cells 900 from the second conveyor belt 410 .

[0181] One end of the second conveyor belt 410 away from the second arc-shaped baffle 430 is adjacent to the transfer unit 500; thus, the transfer unit 500 can be used to transfer the cylindrical battery cells 900 from the second conveyor belt 410 for subsequent other assembly processes.

[0182] In some possible embodiments, see Figures 3 to 7 As shown, the transfer unit 500 includes a first robot 510, a flip mechanism 520, a second conveying member 530 and a second conveying baffle 540;

[0183] A second conveying channel 550 is formed between the second conveying member 530 and the second conveying baffle 540; a plurality of fourth limiting grooves 521 are respectively provided on both sides of the flipping mechanism 520 to accommodate the cylindrical battery cells 900 in a one-to-one manner; the flipping mechanism 520 is flipably mounted beside the second conveying member 530 and connected to the second conveying channel 550; the first manipulator 510 is arranged above the second conveyor belt 410 to transfer the cylindrical battery cells 900 to the fourth limiting grooves 521 of the flipping mechanism 520 away from the second conveying channel 550.

[0184] Specifically, the flip mechanism 520 is an oblong flip frame as a whole, and a plurality of fourth limiting grooves 521 can be arranged at intervals on one side of the flip frame close to the second conveying channel 550 and the other side away from the second conveying channel 550. The first manipulator 510 transfers the horizontally placed cylindrical battery cells 900 from the second conveyor belt 410 to the fourth limiting grooves 521 on the side of the flip mechanism 520 away from the second conveying channel 550.

[0185] The flipping mechanism 520 can flip around the third direction Y, and the flipping angle can be 70°-180°, so that the fourth limiting groove 521 on the side originally far away from the second conveying channel 550 changes to be close to the second conveying channel 550. At the same time, due to the flipping angle of the flipping mechanism 520, the cylindrical battery cell 900 originally placed horizontally can change its angle and can be placed vertically again; furthermore, the cylindrical battery cell 900 placed vertically can be conveniently loaded into the second conveying channel 550, and used to complete subsequent battery packing and other processes.

[0186] Optionally, the first manipulator 510 is a spider arm or a six-axis manipulator to facilitate grasping the cylindrical battery cell 900 .

[0187] Optionally, the fourth limiting groove 521 is a groove body with pneumatic clamps, which is convenient for fixing the cylindrical battery cell 900 so that it can be turned over together.

[0188] Optionally, the fourth limiting groove 521 is a groove body with a magnetic suspension base, so that the flip mechanism 520 flips around the third direction Y, and the fourth limiting groove 521 can limit the cylindrical battery cell 900, and adjust its own angle relative to the flip frame of the flip mechanism 520, ensuring that the horizontally placed cylindrical battery cell 900 can change its own angle and can be placed vertically again. In addition, due to the use of magnetic suspension, the fourth limiting groove 521 has less wear and tear and a longer service life.

[0189] In some possible embodiments, see Figures 3 to 7 As shown, the second conveying member 530 includes a second screw 531 and a second spiral ridge 532. The second screw 531 is rotatably arranged, and the second spiral ridge 532 is spiraled along the axial direction of the second screw 531 and protrudes from the outer periphery of the second screw 531 to form a plurality of second spiral grooves 533 for accommodating the cylindrical battery cells 900 one by one.

[0190] Specifically, the second conveying member 530 is a screw member; the second screw 531 extends along the third direction Y and can rotate around its own axis. The second spiral ridge 532 spirals along the axial direction of the second screw 531 and protrudes from the outer periphery of the first screw 119, thereby defining a plurality of second spiral grooves 533 arranged in sequence along the axial direction of the second screw 531.

[0191] When the second screw 531 rotates around its own axis, the second spiral ridge 532 rotates synchronously with the second screw 531, so that a certain distance is maintained between each two adjacent cylindrical battery cells 900, and the cylindrical battery cells 900 remain in a vertical state and spaced from each other. In this way, the cylindrical battery cells 900 can be better transferred from the second conveying channel 550 to the guide rail 560 (mentioned below), facilitating the completion of subsequent battery packaging and other processes.

[0192] In some possible embodiments, see Figures 3 to 7 As shown, the transfer unit 500 includes a guide rail 560 and a plurality of trays 570 . The guide rail 560 is connected to the second conveying channel 550 . All trays 570 are arranged in the guide rail 560 to accommodate the cylindrical battery cells 900 in the fourth limiting grooves 521 in a one-to-one correspondence.

[0193] By providing a second screw 531 and a second spiral ridge 532, the cylindrical battery cells 900 are transferred from the second conveying channel 550 to the guide rail 560, and each cylindrical battery cell 900 is correspondingly loaded into a tray 570 to avoid wear on the bottom of the cylindrical battery cell 900 and facilitate subsequent battery packaging and other processes.

[0194] In some possible embodiments, see Figures 3 to 7As shown, the installation equipment includes an assembly unit 600 and a support platform 700 for placing a box. The assembly unit 600 is movably arranged between the transfer unit 500 and the support platform 700. The assembly unit 600 is configured to transfer the cylindrical battery cells 900 from the guide rail 560 in batches and place them into the box.

[0195] The assembly unit 600 refers to a structure that can transfer the cylindrical battery cells 900 on the guide rail 560 in batches and assemble them into a box. Specifically, the box is placed on the support platform 700. The assembly unit 600 can grab the cylindrical battery cells 900 from the guide rail 560, and then drive the cylindrical battery cells 900 to move to the top of the box and place the cylindrical battery cells 900 in the box.

[0196] By providing the assembly unit 600 and the carrier 700 , the cylindrical battery cell 900 can be smoothly transferred between the transfer unit 500 and the box body, and the cylindrical battery cell 900 can be assembled into the box body to realize the assembly of the battery.

[0197] In some embodiments, see Figure 3 and Figure 4 As shown, the assembly unit 600 includes a frame 610 and a second manipulator 620; the second manipulator 620 is movably disposed on the frame 610, and the second manipulator 620 is used to grab the cylindrical battery cells 900 on the guide rail 560 in batches and put them into the box.

[0198] The second robot arm 620 can be movably mounted on the frame 610 along the first direction X, the second direction Z and the third direction Y respectively.

[0199] Specifically, the frame 610 may include a first beam 611 extending along the third direction Y and a second beam 612 extending along the first direction X. Two second beams 612 may be provided and spaced apart along the third direction Y. The first beam 611 may be movably provided on the two second beams 612 along the first direction X.

[0200] Furthermore, a telescopic shaft 613 movable along the second direction Z is disposed on the first beam 611, and the telescopic shaft 613 is movably disposed on the first beam 611 along the third direction Y, and the second manipulator 620 is connected to the telescopic shaft 613. In this way, the first beam 611 can drive the second manipulator 620 thereon to move along the first direction X relative to the second beam 612, the telescopic shaft 613 can move along the third direction Y on the first beam 611, and the telescopic shaft 613 can drive the second manipulator 620 to move along the second direction Z by telescoping in the second direction Z.

[0201] Thus, through the above structure, the second manipulator 620 can be moved in three dimensions, so as to grab the cylindrical battery cell 900 from the guide rail 560 and put it into the box.

[0202] Furthermore, the second manipulator 620 may include a plurality of suction cups arranged along the third direction Y; the number of the suction cups may generally be 5-20; the specific number may be subject to design.

[0203] First, each suction cup is controlled to move to the top of the guide rail 560, and the telescopic shaft 613 drives each suction cup to descend to contact with the cylindrical battery cell 900 one by one. The suction cup absorbs the cylindrical battery cell 900, and then moves upward through the telescopic shaft 613. Move on the first beam 611 and the second beam 612 to move the cylindrical battery cell 900 to the top of the box, and then the telescopic shaft 613 drives each cylindrical battery cell 900 to descend to the inside of the box, and the suction cup is released, so that the cylindrical battery cell 900 is arranged in the box.

[0204] By repeating the above process, multiple groups of cylindrical battery cells 900 can be arranged in the box, and the cylindrical battery cells 900 and the box can be assembled.

[0205] Through the above structure, the cylindrical battery cell 900 can be grasped and driven to move, and finally placed inside the box to achieve assembly between the cylindrical battery cell 900 and the box.

[0206] The second aspect of the present application provides a battery production line, comprising the above-mentioned installation equipment. The installation equipment is used to assemble the cylindrical battery cell 900 into a box.

[0207] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0208] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
