It should be understood that the thickness, length and width of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length and width of the integrated device, are only exemplary and should not constitute any limitation on the present application.

[0051] In this application, "multiple" means two or more (including two).

[0052] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery device applications, market demand is also constantly increasing.

[0053] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0054] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0055] In the production process of battery cells within a battery assembly, multiple battery cells are typically placed on a pallet to increase transfer efficiency as they complete upstream processes and are transferred to downstream processes. Upon arrival at the downstream process's inlet, the battery cells need to be removed from the pallet and placed on a transport unit. This transport unit then carries the battery cells to the processing equipment for further processing. Typically, each transport unit carries one battery cell. This results in the time required for transporting the battery cells to and from the processing equipment, as well as for positioning them, representing a significant portion of the overall processing time. This limits the processing cycle time and reduces the overall production efficiency of the battery cells.

[0056] To address the aforementioned technical issues, this application provides a battery production equipment. A transfer conveyor can transport a transfer support to different workstations. At each workstation, corresponding processing devices enable the battery cells on the transfer support to complete different processing steps. The transfer support includes multiple rows of support racks, and each row includes multiple support positions. The transfer conveyor can complete the workstation switching for multiple battery cells in a single transfer. The pre-transfer stage (transfer and positioning) can transfer multiple battery cells at once, reducing the proportion of pre-transfer time in the overall processing time. The processing device at each workstation can simultaneously process multiple battery cells, increasing the processing volume per cycle, improving the processing cycle time, increasing the utilization rate of effective working time, and improving the production efficiency of battery cells.

[0058] Please refer to Figure 1 and Figure 2 According to some embodiments of the present application, a battery production equipment is provided, which comprises a plurality of workstations 10, a transfer support 20, a transfer conveyor 30, and a plurality of processing devices 40. The transfer support 20 comprises a plurality of support rows 20a arranged along a first direction X, each support row 20a comprising a plurality of support positions 21 arranged along a second direction Y, each support position 21 being configured to accommodate one battery cell 100, and the first direction X and the second direction Y intersecting. The transfer conveyor 30 is configured to transfer the transfer support 20 supporting the battery cells 100 between the plurality of workstations 10. Each workstation 10 is provided with a processing device 40 configured to perform a processing operation on the battery cell 100 located on the transfer support 20 of the corresponding workstation 10.

[0059] The battery production equipment can be used to seal the battery cells 100. For example, after the battery cells 100 complete the formation process, the battery cells 100 need to be subjected to secondary liquid injection, and the battery production equipment is used to seal the injection holes of the battery cells 100 after the secondary liquid injection. Optionally, the battery cells 100 can include square batteries and cylindrical batteries.

[0060] The battery cell 100 refers to a battery cell in the preparation process. Exemplarily, the battery cell comprises a shell, the shell comprising a shell body and an end cover, the end cover being covered on the shell body to form an accommodation space. An injection hole is provided on the shell, and the injection hole can communicate the accommodation space with the outside. Before the injection process of the battery cell, the electrode assembly and other components of the battery cell need to be placed in the shell body, and the end cover is covered on the shell body (in the embodiments of the present application, the battery cell which has not been subjected to injection is referred to as the battery cell 100).

[0061] Exemplarily, the workstation 10 refers to an independent station for the processing device 40 to complete a specific processing procedure, and each workstation 10 corresponds to one link in the battery production process (such as a code scanning station, a laser cleaning station, an aluminum nail mounting station, a laser welding station, and a post-welding detection station).

[0062] Optionally, the transfer conveyor 30 can be a conveyor belt, and the plurality of workstations 10 are arranged on at least one side of the conveyor belt, and the plurality of workstations 10 are arranged in sequence along the length direction of the conveyor belt. Optionally, the shape of the transfer conveyor can be linear, curved, or other shapes.

[0063] The transfer support 20 comprises a plurality of support rows 20a arranged along the first direction X, each support row 20a comprising a plurality of support positions 21, in other words, the plurality of support positions 21 are arranged in columns along the first direction X and in rows along the second direction Y. Each support position 21 accommodates one battery cell 100, so that the transfer support 20 can accommodate a plurality of battery cells 100 arranged in columns along the first direction X and in rows along the second direction Y. Optionally, the number of support positions can include at least 24, and exemplarily, the number of support rows is 3, and the number of support positions in each support row is 8.

[0064] The transfer conveyor 30 can carry the transfer support 20 supporting a plurality of battery cells 100 to move between the workstations 10, and the processing device 40 can process a plurality of battery cells 100 on the transfer support 20 synchronously or in batches, and the processing range can cover all the support positions 21 on the support.

[0065] In the embodiment of the present application, the battery production equipment can include a plurality of stages, such as a feeding stage, a transfer stage, a processing stage, and a discharging stage. In the feeding stage, at the starting end of the equipment (such as a feeding workstation), a plurality of battery cells 100 to be processed are placed one by one into the support positions 21 of the transfer support 20, until all the support positions 21 of the transfer support 20 accommodate battery cells 100. In the transfer stage, the transfer conveyor 30 is started to carry the transfer support 20 loaded with battery cells 100 to move along a predetermined path until it is delivered to the first workstation 10 and transported to a specific position of the workstation 10. In the processing stage, the processing device 40 of the first workstation 10 is started to synchronously or in batches complete the positioning and other pre-processes of all the battery cells 100 on the transfer support 20, and then process at least one or all the battery cells 100 (such as welding the battery cells 100), after the processing is completed, the transfer conveyor 30 is started again to deliver the transfer support 20 to the next workstation 10, and repeat the positioning and processing process until the transfer support 20 passes through all the workstations 10 in sequence to complete all the processing procedures of the battery cells 100. In the discharging stage, the transfer support 20 that has completed all the processing procedures is delivered by the transfer conveyor 30 to the end of the equipment (such as a discharging workstation), and the processed battery cells 100 are taken out of the support positions 21, and the empty transfer support 20 can flow back to the starting end for repeated use.

[0066] Optionally, the processing device 40 can process a plurality of battery cells 100 at the same time; or the processing device 40 processes a plurality of battery cells 100 in sequence.

[0067] In battery production equipment, the transfer conveyor 30 can transfer the transfer support 20 to different workstations 10.

The transfer support 20 includes multiple rows of support rows 20a, and each row of support rows 20a includes multiple support positions 21. The transfer conveyor 30 can complete the workstation switching of multiple battery cells 100 in one transfer. The pre-transfer link (transfer and positioning) can transfer multiple battery cells 100 at one time, reducing the proportion of pre-transfer time in the overall processing time. At the same time, the processing device 40 of each workstation 10 can process multiple battery cells 100 simultaneously, increasing the processing volume per batch, improving the processing cycle, increasing the utilization rate of effective working time, and improving the production efficiency of battery cells 100.

[0068] Figure 3 This is a schematic diagram of the structure of a cleaning station in a battery production equipment provided in some embodiments of this application. The arrangement of processing devices and workstations in the sealing assembly station, the welding station, and the post-weld inspection station can all refer to the arrangement of processing devices and workstations in the cleaning station.

[0069] In some alternative embodiments, please refer to Figure 3 The processing device 40 includes at least two processing parts 41, and each work station 10 is provided with at least two processing parts 41. The at least two processing parts 41 are configured to operate simultaneously to process at least two battery cells 100.

[0070] The processing part 41 is a processing unit that can be processed independently, such as a laser welding head or a vision component. Multiple processing parts 41 in each work station 10 can be the same, so that the processing device 40 in each work station 10 can process multiple battery cells 100 simultaneously.

[0071] For example, at least two processing components 41 include a first processing component and a second processing component. The first processing component processes the battery cells 100 of the first row of support rows, and the second processing component processes the battery cells 100 of the second row of support rows. Optionally, the first processing component and the second processing component can process the battery cells 100 of two adjacent rows of support rows simultaneously; or, the first processing component processes the battery cells 100 of the odd-numbered rows of support rows, and the second processing component processes the battery cells 100 of the even-numbered rows of support rows; or, the first processing component processes the battery cells 100 of the first to Nth rows of support rows, and the second processing component processes the battery cells 100 of the Mth to N+1th rows of support rows, where M > N.

[0072] In these alternative embodiments, the above-described configuration helps to improve the processing efficiency of the battery cell 100, increase the proportion of effective processing time in the total processing time, and improve production efficiency.

[0073] In some alternative embodiments, please continue to refer to Figure 3 At least two processing parts 41 are spaced apart along the first direction X to process the battery cells 100 of different rows of support rows 20a.

[0074] For example, there are two processing components 41, which are spaced apart along the first direction X. The two processing components 41 can operate simultaneously to process the battery cells 100 supported by the two rows of support rows 20a. Of course, the number of processing components can also include more than two, such as three, four or even more. Multiple processing components 41 process the battery cells 100 of different rows of support rows 20a.

[0075] In the embodiments of this application, the above-mentioned settings are beneficial to improving processing efficiency, reducing the possibility of interference between multiple processed parts during the preparation process, and expanding the applicability of battery production equipment.

The processing part 41 on the first work station 11 can process a portion of the battery cells 100 housed in the support row 20a of the transfer support 21, and the processing part 41 on the second work station 12 can process another portion of the battery cells 100 housed in the support row 20a of the transfer support 21.

The lifting assembly 44 is used to at least drive the battery cell 100 to move toward the first positioning member 43 so that the battery cell 100 abuts against the positioning part 431.

[0088] Optionally, the first positioning member 43 has a plurality of positioning parts 431, and the number of positioning parts 431 may be the same as the number of battery cells 100 (or support positions 21).

[0089] Optionally, the lifting assembly 44 can drive multiple battery cells 100 to move synchronously toward the positioning element.

[0090] In this embodiment, after the transfer conveyor 30 transfers the transfer support 20 to the work position 10, the lifting assembly 44 is activated, driving at least the battery cell 100 to move towards the positioning part, so that the battery cell 100 abuts against the positioning part 431, thereby performing upper reference positioning on the battery cell, eliminating fixture deviation, reducing the possibility of electrolyte contamination and excessive assembly gap, and improving the positioning accuracy and processing accuracy of the battery cell 100.

[0091] In some alternative embodiments, please refer to Figure 3 and Figure 4 The positioning part 431 is provided with a machining hole 432, and the machining part is positioned above the first positioning part and is configured to process the battery cell through the machining hole 432.

[0092] For example, the machining hole 432 can be used to expose the liquid injection hole of the battery cell 100 so that the aluminum nailing mechanism, welding mechanism, etc. can pass through the positioning part 431 to perform aluminum nailing, welding and other processes on the liquid injection hole, thereby reducing the possibility of deviation between the battery cell and the machining mechanism after the battery cell is positioned on the upper reference, so as to maintain the positioning accuracy of the battery cell.

[0093] Optionally, the positioning part 431 may include two sub-parts, with a machining hole 432 disposed between the two sub-parts, and the two sub-parts abutting against the same battery cell 100. Of course, the machining hole 432 may also be a through hole that penetrates the positioning part 431.

[0094] In some alternative embodiments, please refer to Figure 4 Each support position 21 includes a support portion 211 and an opening portion 212. The lifting assembly 44 includes a plurality of lifting units 441. The lifting units 441 are configured to lift the battery cell 100 through the opening portion 212 and move it toward the first positioning member 43 so that the battery cell 100 abuts against the positioning portion 431.

[0095] For example, in the support position 21, the support portion supports a part of the battery cell 100, and another part of the battery cell 100 is exposed to the opening 212. When it is necessary to lift the battery cell 100, the lifting unit 441 passes through the opening 212 to contact the battery cell 100 and lift the battery cell 100 so that the battery cell 100 is separated from the support position 21 and the battery cell 100 is lifted to contact the positioning portion 431.

[0096] Optionally, multiple lifting units 441 can be controlled independently or synchronously.

[0097] Multiple lifting units 441 are configured in a one-to-one correspondence with multiple openings 212.

[0098] Optionally, the opening 212 and the positioning part 431 are positioned opposite each other, so that the lifting position of the lifting unit 441 is positioned opposite to the processing area of ​​the battery cell 100, so that the lifting force and the force during processing cancel each other out, thereby reducing the possibility of deformation of the battery cell 100.

[0099] In these alternative embodiments, the opening 212 provides lifting space for the lifting unit 441, which directly lifts the battery cell 100. This helps to improve the control accuracy of the lifting height, while reducing the lifting force of the lifting assembly 44, reducing the energy consumption of the lifting assembly 44, and reducing the production cost of the battery cell 100.

[0100] In some alternative embodiments, please refer to Figure 3 and Figure 5 The transfer support 20 includes a support plate 23 with multiple rows of support rows. The lifting assembly 44 is configured to lift the support plate 23 to move towards the first positioning member 43 so that the battery cell 100 abuts against the positioning part 431.

[0101] Optionally, the transfer support 20 may include a support frame 45, which encloses a support space 22. The bottom wall of the support frame 45 may have a hollow structure, and the support plate 23 is placed on the hollow structure.

[0102] In this embodiment of the application, by setting the support plate 23, the lifting assembly 44 can move the battery cells 100 in the multiple rows of support rows 20a synchronously as a whole, thereby simplifying the overall structure of the lifting assembly 44, reducing the total lifting time of the lifting assembly 44, and further improving the production cycle.

[0103] In some alternative embodiments, please refer to Figure 6 The support plate 23 includes multiple support sub-plates 231, which are arranged along the first direction X. Each support sub-plate 231 is provided with a support row 20a. The lifting assembly 44 includes multiple lifting members, which lift different support sub-plates 231 respectively.

[0104] For example, each support subplate 231 is provided with a row of support rows 20a. The lifting member can sequentially lift different support subplates 231 according to the processing sequence to facilitate the processing of different rows of battery cells 100. Optionally, the first lifting member can lift the first support subplate 231 first, so that the first row of battery cells 100 abuts against the positioning part 431. After the processing of the first row of battery cells 100 is completed, the second lifting member lifts the second support subplate 231, so that the second row of battery cells 100 abuts against the positioning part 431, thereby processing the second row of battery cells 100. At the same time, the impact of vibration or internal load generated during the processing of the second row of battery cells 100 on the first row of battery cells 100 is reduced, and the processing accuracy is improved. Of course, multiple lifting members can also lift multiple support subplates simultaneously.

[0105] In this embodiment, each support subplate 231 can be raised and lowered independently, which helps to improve the consistency of the lifting height of each row of support subplates 20a and the uniformity of the contact force between the battery cells 100 in the same row and the positioning part. By setting multiple lifting components, it is beneficial to reduce the possibility that the lifting position of different support subplates 231 will be inconsistent due to movement error caused by the lifting assembly 44 moving to the bottom of different support subplates 231, thereby improving the uniformity of the contact force between the battery cells 100 in different support subplates 231 and the positioning part, and reducing the production differences of battery cells 100 in different rows.

[0106] In some alternative embodiments, please continue to refer to Figure 3 The processing device 40 also includes a frame 45 and a second positioning member. The first positioning member 43 and the second positioning member are both disposed on the frame 45. The second positioning member is used to position the transfer support member 20 so that the positioning part 431 and the support position 21 are disposed opposite to each other along the gravity direction Z.

[0107] Optionally, the frame 45 can provide installation space and positioning reference for the first positioning member 43 and the second positioning member.

[0108] Optionally, the second positioning member can be located between the first positioning member 43 and the transfer support member 20; or, the second positioning member can be located on the side of the transfer support member 20 facing away from the first positioning member 43; or, the second positioning member can also be located on the side of the first positioning member 43 facing away from the transfer support member 20, and the first positioning member 43 can be provided with a clearance structure to facilitate the second positioning member to position the transfer support member 20.

[0109] Optionally, the second positioning element can be a positioning sensor, an elastic positioning block, or other similar device.

[0110] For example, after the transfer conveyor 30 transfers the transfer support 20 to the work station 10 (such as a laser cleaning station, an aluminum nail installation station, or a welding station), the second positioning member can position the transfer support 20 so that the positioning part 431 is positioned opposite to the support position 21. Then, the lifting assembly 44 lifts the battery cell 100 and moves it towards the first positioning member 43 so that the battery cell 100 abuts against the positioning part 431 to complete the positioning of the battery cell 100. Subsequently, the position information of the liquid injection hole of the battery cell 100 can be obtained by a vision component (such as a camera). Based on the obtained position information, the liquid injection hole of the battery cell 100 can be processed (such as laser cleaning, assembly of aluminum nails and liquid injection holes, welding).

[0111] For example, after the transfer conveyor 30 transfers the transfer support 20 to the work station 10 (such as the post-weld inspection station), the second positioning member can position the transfer support 20 so that the positioning part 431 is positioned opposite to the support position 21. Then, the lifting assembly 44 lifts the battery cell 100 and moves it towards the first positioning member 43 so that the battery cell 100 abuts against the positioning part 431 to complete the positioning of the battery cell 100. Subsequently, the filling hole of the battery cell 100 can be inspected by a vision component (such as a camera) to determine whether there are any defects.

[0112] In this embodiment of the application, by setting a second positioning member, it is beneficial to improve the alignment accuracy between the battery cell 100 and the positioning part 431, reduce the possibility of misalignment when the battery cell 100 and the positioning part 431 come into contact, and improve the accuracy of subsequent processing.

[0113] In some alternative embodiments, please continue to refer to Figure 1The work station 10 includes a cleaning station 13, a sealing assembly station 14, and a welding station 15. Each of the cleaning station 13, the sealing assembly station 14, and the welding station 15 is equipped with at least one processing device 40. The transfer conveyor 30 is used to sequentially pass the transfer support 20 supporting the battery cell 100 through the cleaning station 13, the sealing assembly station 14, and the welding station 15.

[0114] Cleaning station 13 is used to clean the electrolyte injection holes of the battery cell 100, removing residual electrolyte and improving the yield of subsequent welding. Optionally, the electrolyte injection holes of the battery cell can be cleaned by laser cleaning. Optionally, the processing device 40 may include a laser cleaning device, which is disposed at cleaning station 13.

[0115] The sealing assembly station 14 is used to remove the sealing element (such as an aluminum nail) of the sealing injection hole from the storage tray, transport it to the injection hole of the battery cell, and assemble the sealing element into the injection hole. Optionally, the processing device 40 may include an aluminum nail mounting device, which is disposed at the sealing assembly station 14.

[0116] The welding station 15 is used to weld the seal to the housing of the battery cell 100 to seal the injection hole. Optionally, the processing device 40 may include a laser welding device, which is disposed at the welding station 15.

[0117] Optionally, the work station 10 may further include a post-weld inspection station 16, which is used to inspect the weld between the seal and the casing in the battery cell.
