[0002] During the production of battery modules and / or battery packs, abnormalities in the cell assembly or module processing may occur. In this case, the line usually needs to be stopped and the cells need to be manually reassembled for replenishment and replacement, which leads to low production efficiency and affects the output of the entire line. Summary of the invention

[0003] In view of this, the embodiments of the present disclosure at least provide a battery production control method and system, which can automatically replenish battery cells without stopping the production line when failed battery products are produced during the battery production process, thereby reducing manual intervention and improving production efficiency.

[0004] The technical solution of the embodiment of the present disclosure is implemented as follows:

[0005] The present disclosure provides a battery production control method, including:

[0006] The controller of any section in the battery production line determines the number of cells corresponding to the failed battery product in response to detecting that a failed battery product is produced in the process flow of the section;

[0007] The controller sends the number of battery cells to the upper computer of the section;

[0008] In response to receiving the number of battery cells, the host computer controls the battery cell loading mechanism in the first section of the battery production line to supplement the number of battery cells.

[0009] In the disclosed embodiment, the controller of any section in the battery production line determines the number of cells corresponding to the failed battery product in response to detecting that a failed battery product is generated in the process flow of the section, and sends the number of cells to the host computer of the section. In response to receiving the number of cells, the host computer controls the cell feeding mechanism in the first section of the battery production line to replenish the number of cells. In this way, when a failed battery product is generated during the battery production process, the cell feeding can be automatically performed from the beginning of the battery production line without stopping the line, reducing manual intervention and improving production efficiency.

[0010] In some embodiments, the battery production line includes a battery module section, and the first section is the battery module section; the controller of any section in the battery production line determines the number of battery cells corresponding to the failed battery product in response to detecting that a failed battery product is generated in the process flow of the section, including: the first controller of the battery module section determines the first number of battery cells corresponding to the failed battery product in response to detecting that a failed battery product is generated in the process flow of the battery module section; the failed battery product includes failed battery cells and / or failed modules; the host computer controls the battery cell loading mechanism in the first section of the battery production line to supplement the loading of the battery cell number in response to receiving the battery cell number, including: the first host computer of the battery module section controls the battery cell loading mechanism in the battery module section to supplement the loading of the first number of battery cells in response to receiving the first battery cell number.

[0011] In this way, when failed cells and / or failed modules are generated during the battery production process, the cells can be automatically replenished without stopping the production line, thereby reducing manual intervention and improving production efficiency.

[0012] In some embodiments, the failed battery product includes a failed battery cell, and the battery module section includes a side gluing station; the first controller of the battery module section determines a first number of battery cells corresponding to the failed battery product in response to detecting that a failed battery product is generated in the process flow of the battery module section, including: the first controller controls a side gluing detection mechanism to perform a gluing detection on the battery cell after side gluing in the side gluing station to obtain a first gluing detection result; the first controller characterizes that the side gluing of the battery cell is abnormal in response to the first gluing detection result, determines the battery cell as a failed battery cell, and determines the number of the failed battery cells as the first number of battery cells.

[0013] In this way, when abnormal glue sticking on the side of the battery cell is detected, the battery cell can be regarded as a failed battery cell, and new battery cells equal to the number of failed batteries can be automatically replenished at the battery cell feeding mechanism, thereby reducing the impact of the abnormal glue sticking on the side of the battery cell on the battery production process.

[0014] In some embodiments, the failed battery product includes failed battery cells, and the battery module section includes a large-surface gluing station; the first controller of the battery module section determines the first number of battery cells corresponding to the failed battery product in response to detecting that the failed battery product is generated in the process flow of the battery module section, including: the first controller controls the large-surface gluing detection mechanism to perform gluing detection on the battery cell pairs after large-surface gluing in the large-surface gluing station to obtain a second gluing detection result; the first controller characterizes that the large-surface gluing of the battery cell pair is abnormal in response to the second gluing detection result, determines each battery cell in the battery cell pair as a failed battery cell, and determines the number of the failed batteries as the first number of batteries.

[0015] In this way, when an abnormality in the adhesive bonding of the large surface of a battery cell pair is detected, the corresponding battery cell pair can be regarded as failed batteries, and new batteries equal to the number of failed batteries can be automatically replenished at the battery cell feeding mechanism, thereby reducing the impact of the abnormality in the adhesive bonding of the large surface of the battery cell on the battery production process.

[0016] In some embodiments, the failed battery product includes a failed module; the controller sends the number of battery cells to the host computer of the section, including: the first controller sends the first number of battery cells and the module type of the failed module to the first host computer; the method also includes: the first host computer inserts a new module into the current queue of modules to be assembled in the battery module section based on the module type of the failed module, and the module type of the new module is the same as the module type of the failed module.

[0017] In this way, when a failed module is generated during the battery production process, on the one hand, it can automatically replenish materials from the battery cell feeding mechanism for supplementing and assembling new modules, and on the other hand, the first host computer inserts a new module of the same module type as the failed module into the current queue of modules to be assembled in the battery module section based on the module type of the failed module. Therefore, by replenishing materials from the battery cell feeding mechanism for supplementing and assembling new modules and adjusting the current queue of modules to be assembled in the battery module section, it is possible to achieve automatic replenishment and assembly of modules without stopping the line, reduce manual intervention, and improve production efficiency.

[0018] In some embodiments, the first host computer inserts a new module into the current queue of modules to be assembled in the battery module section based on the module type of the failed module, including: the first host computer inserts the new module into the head of the queue of modules to be assembled.

[0019] In this way, after the currently assembled module is completed, a new module of the same type as the failed module can be added to the queue for supplementary assembly, thereby reducing the impact of module failure on the battery production process.

[0020] In some embodiments, the battery module section includes a module pressurizing station; the first controller of the battery module section determines the first number of battery cells corresponding to the failed battery product in response to detecting that a failed battery product is generated in the process flow of the battery module section, including: the first controller controls the pressurizing detection mechanism to detect the status information corresponding to the pressurized module in the module pressurizing station to obtain a pressurizing detection result; the status information includes pressurizing pressure and / or module size; the first controller determines the module as a failed module in response to the pressurizing detection result characterizing that the status information of the module is abnormal, and determines the first number of battery cells based on the module type of the failed module.

[0021] In this way, when it is detected that the status information corresponding to the pressurized module is abnormal, the module can be treated as a failed module, and the battery cell feeding mechanism can automatically replenish the battery cells of the first number corresponding to the module type of the failed module, thereby reducing the impact of the abnormality of the pressurized module on the battery production process.

[0022] In some embodiments, the battery module section includes a module scanning station; the first controller of the battery module section determines the first number of battery cells corresponding to the failed battery product in response to detecting that a failed battery product is generated in the process flow of the battery module section, including: the first controller controls the module scanning detection mechanism to scan each battery cell in the module in the module scanning station to obtain a first battery cell code of each battery cell in the module; the first controller obtains a set of second battery cell codes corresponding to the module recorded during the assembly process of the module; the first controller uses the second battery cell code set to verify the first battery cell code of each battery cell in the module to obtain a scanning verification result; the first controller determines the module as a failed module in response to the scanning verification result indicating that the battery cell code of at least one battery cell in the module is abnormal, and determines the first number of battery cells based on the module type of the failed module.

[0023] In this way, when it is detected that the cell code of at least one cell in the module is abnormal, the module can be treated as a failed module, and the cell feeding mechanism can automatically replenish the first number of cells corresponding to the module type of the failed module, thereby reducing the impact of the abnormal cell code of at least one cell in the module on the battery production process.

[0024] In some embodiments, the battery module section includes an insulation and voltage resistance testing station; the first controller of the battery module section determines the first number of battery cells corresponding to the failed battery product in response to detecting that a failed battery product is produced in the process flow of the battery module section, including: the first controller controls the insulation and voltage resistance testing mechanism to perform insulation and voltage resistance testing on the module in the insulation and voltage resistance testing station to obtain an insulation test result of the module; the first controller determines the module as a failed module in response to the insulation test result characterizing poor insulation between battery cells in the module and / or poor insulation between battery cells and module casing, and determines the first number of battery cells based on the module type of the failed module.

[0025] In this way, when poor insulation between battery cells in the module and / or poor insulation between battery cells and the module casing is detected, the module can be treated as a failed module, and the battery cell feeding mechanism can automatically replenish the battery cells of the first number corresponding to the module type of the failed module, thereby reducing the impact of poor insulation between battery cells in the module and / or poor insulation between battery cells and the module casing on the battery production process.

[0026] In some embodiments, the battery production line includes a battery pack section, the first section is the battery module section, and the failed battery product includes a failed battery pack; the controller of any section in the battery production line determines the number of battery cells corresponding to the failed battery product in response to detecting that a failed battery product is generated in the process flow of the section, including: the second controller of the battery pack section determines the second number of battery cells corresponding to the failed battery pack in response to detecting that a failed battery pack is generated in the process flow of the battery pack section; the host computer controls the battery cell loading mechanism in the first section of the battery production line to supplement the loading of the battery cell number in response to receiving the battery cell number, including: the second host computer of the battery pack section controls the battery cell loading mechanism in the battery module section to supplement the loading of the second number of battery cells in response to receiving the second number of battery cells.

[0027] In this way, when a failed battery pack is generated in the process flow of the battery pack section, the battery cell feeding mechanism can be automatically replenished without stopping the line to re-produce a new battery pack corresponding to the failed battery pack, thereby reducing manual intervention and improving production efficiency.

[0028] In some embodiments, the second host computer of the battery pack section controls the cell loading mechanism in the battery module section to supplement the loading of the second number of cells in response to receiving the second number of cells, including: the second host computer reports the second number of cells to the production execution system in response to receiving the second number of cells; the production execution system adds a module assembly work order based on the second number of cells, and sends the newly added module assembly work order to the first host computer of the battery module section; the first host computer controls the cell loading mechanism to supplement the loading of the second number of cells based on the module assembly work order, so that the production equipment in the cell production line supplements the production of new battery packs corresponding to the failed battery packs based on the second number of cells.

[0029] In this way, when a failed battery pack is generated in the process flow of the battery pack section, the second controller of the battery pack section reports the second number of cells corresponding to the failed battery pack to the production execution system through the second host computer of the battery pack section. The production execution system can add a module assembly work order based on the package information of the failed battery pack, and send the newly added module assembly work order to the first host computer, so that the first host computer controls the cell feeding mechanism to replenish the cells of the second number of cells based on the module assembly work order. In this way, it is possible to automatically start replenishing materials from the cell feeding mechanism without stopping the line to re-produce a new battery pack corresponding to the failed battery pack, reduce manual intervention, and improve production efficiency.

[0030] In some embodiments, the second controller of the battery pack section determines the second number of battery cells corresponding to the failed battery pack in response to detecting that a failed battery pack is generated in the process flow of the battery pack section, including: the second controller controls the transportation equipment carrying the battery pack to transport the battery pack from the current workstation to the maintenance cache area in response to detecting that a failed battery pack is generated in the process flow of the battery pack section, and adds the package information of the battery pack to the preset list of battery packs to be repaired; the second controller controls the transportation equipment to transport the battery pack from the maintenance cache area to the current workstation in response to a confirmation operation on the completion of maintenance of the battery pack, and clears the package information of the battery pack from the list of battery packs to be repaired; the second controller determines the battery pack as a failed battery pack in response to a confirmation operation on the failure of maintenance of the battery pack, and determines the number of battery cells required to assemble the failed battery pack as the second number of battery cells corresponding to the failed battery pack.

[0031] In this way, by setting up a maintenance cache area, after the battery pack detected to have an abnormality is transported to the maintenance cache area, on the one hand, when the maintenance is completed, a maintenance completion confirmation operation can be performed to trigger the second controller to control the transportation equipment to transport the battery pack from the maintenance cache area back to the production line, and the package information of the battery pack can be cleared from the list of battery packs to be repaired, so that the battery pack after the maintenance is completed can continue to return to the production line, thereby reducing the waste of material costs and process costs; on the other hand, when the maintenance fails, a maintenance failure confirmation operation can be performed to trigger the second controller to determine the battery pack as a failed battery pack, and report the second battery cell number corresponding to the failed battery pack to the second host computer, so that it is possible to automatically start replenishing materials from the battery cell loading mechanism without stopping the line, so as to re-produce a new battery pack corresponding to the failed battery pack.

[0080] Step S103 , in response to receiving the number of battery cells, the host computer controls the battery cell feeding mechanism in the first section of the battery production line to supplement the number of battery cells.

[0081] Here, the controller of a section in a battery production line can be used to control the mechanisms in each station in the section to implement the process flow corresponding to the section. In implementation, the controller can be, for example, an industrial computer, a programmable logic controller (PLC), etc.

[0082] The host computer may be used to control the process flow in the section. In implementation, the first host computer may be at least one of a server, a notebook computer, a tablet computer, a desktop computer, a smart phone, etc.

[0083] Failed battery products may be unqualified battery products produced in a section of a battery production line, and may include but are not limited to at least one of failed battery cells, failed modules, failed battery packs, etc. It is understandable that failed battery products produced in the process flow of each section may be semi-finished battery products or finished battery products, and the embodiments of the present disclosure are not limited to this.

[0084] In some embodiments, the first section of the battery production line may be a battery module section.

[0085] In the disclosed embodiment, the controller of any section in the battery production line determines the number of cells corresponding to the failed battery product in response to detecting that a failed battery product is generated in the process flow of the section, and sends the number of cells to the host computer of the section. In response to receiving the number of cells, the host computer controls the cell feeding mechanism in the first section of the battery production line to replenish the number of cells. In this way, when a failed battery product is generated during the battery production process, the cell feeding can be automatically performed from the beginning of the battery production line without stopping the line, reducing manual intervention and improving production efficiency.

[0086] In some embodiments, the battery production line includes a battery module section, and the first section is the battery module section.

[0087] The above-mentioned step S101 may include: step S111, the first controller of the battery module section determines the first number of battery cells corresponding to the failed battery products in response to detecting that failed battery products are generated in the process flow of the battery module section; the failed battery products include failed battery cells and / or failed modules.

[0088] The above-mentioned step S103 may include: step S112, in response to receiving the first number of battery cells, the first host computer of the battery module section controls the battery cell feeding mechanism in the battery module section to supplement the battery cells of the first number of battery cells.

[0089] Here, the battery module section refers to the section used to produce modules in the battery production process. The battery module section may include multiple workstations, and multiple battery cells can be assembled into modules after being processed by each workstation in the battery module section.

[0090] During implementation, the workstations included in the battery module section may be determined based on actual production requirements, and the embodiments of the present disclosure are not limited to this.

[0091] In some embodiments, the battery module section may include but is not limited to at least one of a cell loading station, a side gluing station, a small unit grouping station, a large surface gluing station, a cell stacking station, a module pressurizing station, a module code scanning station, and an insulation withstand voltage testing station. The cell loading station includes a cell loading mechanism, which can be used to load the cells required for the assembly module. The side gluing station includes a side gluing mechanism and a side gluing detection mechanism, which can be used to glue the sides of the loaded cells, and the side gluing detection mechanism can be used to perform glue detection on the cells after side gluing. The small unit grouping station includes a small unit grouping mechanism, which can be used to group the sides of the cells relative to each other. The large-surface gluing station includes a large-surface gluing mechanism and a large-surface gluing detection mechanism, which can be used to glue the large surfaces of the grouped battery cell pairs, and the large-surface gluing detection mechanism can be used to perform glue detection on the battery cell pairs after large-surface gluing. The battery cell stacking station may include a battery cell stacking mechanism, which can be used to stack multiple battery cell pairs after large-surface gluing into modules. The module pressurizing station includes a module pressurizing mechanism and a pressurizing detection mechanism, which is used to pressurize the modules after the battery cells are stacked according to the preset pressure and module size, and the pressurizing detection mechanism is used to detect the pressurization pressure and / or module size and other status information corresponding to the pressurized module. The module code scanning station may include a module code scanning detection mechanism, which can be used to verify each battery cell in the module. The insulation withstand voltage detection station may include an insulation withstand voltage detection mechanism, which can be used to perform insulation withstand voltage detection on the module.

[0092] The first controller of the battery module section can be used to control the mechanisms in each workstation in the battery module section so that the mechanisms in each workstation cooperate to realize the assembly of the module. In addition, the first controller can also use the mechanism in the workstation to detect whether a failed battery product is generated in the process flow of the battery module section. Among them, the failed battery product may include but is not limited to at least one of failed battery cells, failed modules, etc. It can be understood that the modules included in the process flow of the battery module section can be semi-finished modules (for example, modules that have not been pressurized after the battery cells are stacked) or finished modules (for example, modules that have been pressurized by a module pressurizing mechanism), and the embodiments of the present disclosure are not limited to this.

[0093] In some embodiments, the first controller may refer to a lower computer in the battery module section, such as an industrial computer, a PLC, etc. It should be noted that the first controller may be a separate controller, which may control the mechanisms in each station in the battery module section as a whole; the first controller may also include a plurality of first sub-controllers, each of which may control a mechanism in the battery module section respectively, and the embodiments of the present disclosure are not limited to this.

[0094] The first number of cells corresponding to the failed battery product refers to the number of cells in the failed battery product. After determining the first number of cells, the first controller can send the first number of cells to the first host computer of the battery module section. After receiving the first number of cells, the first host computer can control the cell feeding mechanism in the battery module section to supplement the cells of the first number of cells. In this way, the cells required for the currently assembled module can be supplemented.

[0095] It is understandable that the first host computer can be a host computer for controlling the process flow of the modules in the battery module section. In implementation, the first host computer can be at least one of a server, a laptop, a tablet computer, a desktop computer, a smart phone, etc.

[0096] In some embodiments, when the failed battery product is a failed cell, the first cell number corresponding to the failed cell is the number of the failed cells. For example, when the failed cell is a single cell, the first cell number corresponding to the failed cell is 1, and the first host computer can control the cell feeding mechanism in the battery module section to feed one cell; when the failed cell is a cell pair, the first cell number corresponding to the failed cell is 2, and the first host computer can control the cell feeding mechanism in the battery module section to feed two cells.

[0097] In some embodiments, when the failed battery product is a failed module, the first number of cells corresponding to the failed module is the number of cells contained in the failed module. For example, when the failed module contains 16 cells, the first number of cells corresponding to the failed module is 16, and the first host computer can control the cell feeding mechanism in the battery module section to feed 16 cells for supplementing and assembling a new module of the same type as the failed module.

[0098] It should be noted that the communication between the first controller and the first host computer, and between the first controller and the mechanisms in each workstation in the battery module section, can be achieved through a wired network or a wireless network, and the embodiments of the present disclosure are not limited to this. In some embodiments, the first controller and the first host computer, and between the first controller and the mechanisms in each workstation in the battery module section can communicate through industrial Ethernet. For example, industrial Ethernet may include an automation bus standard network (PROFINET) and the like.

[0099] In the above embodiment, in response to detecting that a failed battery product is generated in the process flow of the battery module section, the first controller of the battery module section determines and sends the first number of battery cells corresponding to the failed battery product to the first host computer of the battery module section. Based on the first number of battery cells, the first host computer controls the battery cell feeding mechanism in the battery module section to replenish the battery cells of the first number of battery cells, wherein the failed battery product includes failed battery cells and / or failed modules. In this way, when failed battery cells and / or failed modules are generated during the battery production process, the battery cells can be automatically replenished without stopping the production line, reducing manual intervention and improving production efficiency.

[0100] In some embodiments, the failed battery product includes a failed battery cell, and the battery module section includes a side glue sticking station. The above step S111 may include the following steps S121 to S122:

[0101] Step S121, the first controller controls the side glue detection mechanism to perform glue detection on the battery cells after side glue is applied in the side glue station to obtain a first glue detection result.

[0102] Step S122: In response to the first adhesive detection result indicating that the adhesive on the side of the battery cell is abnormal, the first controller determines the battery cell as a failed battery cell, and determines the number of the failed battery cells as the first number of battery cells.

[0103] In the process flow of the battery module section, there are certain process requirements for the side glue of the battery cell. The first controller can control the side glue detection mechanism to perform glue detection on the battery cell after the side glue is applied, and obtain a first glue detection result, which can indicate whether the side glue of the battery cell meets the process requirements, that is, whether the side glue of the battery cell is abnormal.

[0104] In some embodiments, the process requirements that need to be met by the glue on the side of the battery cell may include but are not limited to at least one of the following: the glue position meets the preset first position requirement, the film release paper is completely peeled off, etc. During implementation, the side glue detection mechanism can be used to detect the position of the glue on the side of the battery cell and / or the peeling state of the release paper to obtain the first glue detection result. Among them, when it is detected that the position of the glue on the side of the battery cell does not meet the preset first position requirement, or the release paper of the glue on the side of the battery cell is not completely peeled off, it can be determined that the first glue detection result of the battery cell is that the side glue does not meet the process requirements, that is, the side glue of the battery cell is abnormal.

[0105] The first position requirement may be predetermined by those skilled in the art according to the actual production process, and the embodiments of the present disclosure are not limited thereto.

[0106] In some embodiments, Figure 2 As shown, the first position requirement that needs to be met by the cell side glue may include that the distance d1 between the upper edge of the first film 120 pasted on the cell side 110 and the cell top patch is within a preset first distance range, the lower edge of the first film 120 does not exceed the bottom of the cell side 110, and the side of the first film 120 does not exceed the side of the cell side 110. Among them, the first distance threshold can be a suitable value set by those skilled in the art according to actual conditions, and the embodiments of the present disclosure are not limited to this. For example, the first distance range can be 0 to 2 millimeters (mm).

[0107] The side glue detection mechanism can use any suitable method to perform glue detection on the battery cell after the side glue is applied, and the embodiments of the present disclosure are not limited to this. For example, the side glue detection mechanism can include a charge coupled device (CCD) camera, and the CCD camera is used to take a picture of the side of the battery cell to obtain an image of the side of the battery cell. By identifying the position of the film and / or the peeling state of the release paper in the image, the first glue detection result can be obtained.

[0108] In some embodiments, when the first gluing detection result indicates that the side gluing of the battery cell is abnormal, the first controller can control the battery cell conveying mechanism of the side gluing station to flow the battery cell tray carrying the failed battery cell out of the production line from the abnormal discharge port of the side gluing station. After the failed battery cell is manually removed, the battery cell conveying mechanism can return the empty battery cell tray to the production line.

[0109] In the above embodiment, when abnormal glue sticking on the side of the battery cell is detected, the battery cell can be regarded as a failed battery cell, and new battery cells equal to the number of failed batteries can be automatically replenished at the battery cell feeding mechanism, thereby reducing the impact of the abnormal glue sticking on the side of the battery cell on the battery production process.

[0110] In some embodiments, the failed battery product includes a failed battery cell, and the battery module section includes a large-surface glue sticking station. The above step S111 may include the following steps S131 to S132:

[0111] Step S131, the first controller controls the large-surface glue-laminating detection mechanism to perform glue-laminating detection on the battery cell pairs after large-surface glue-laminating in the large-surface glue-laminating station to obtain a second glue-laminating detection result.

[0112] Step S132, in response to the second adhesive detection result indicating that the adhesive on the large surface of the battery cell pair is abnormal, the first controller determines each battery cell in the battery cell pair as a failed battery cell, and determines the number of the failed batteries as the first number of batteries.

[0113] In the process flow of the battery module section, there are certain process requirements for the large-surface gluing of the battery cells. The first controller can control the large-surface gluing detection mechanism to perform a gluing detection on the battery cell pair after large-surface gluing to obtain a second gluing detection result, which can indicate whether the large-surface gluing of the battery cell in the battery cell pair meets the process requirements, that is, whether the large-surface gluing of the battery cell pair is abnormal.

[0114] In some embodiments, the process requirements that need to be met by gluing the large surface of the battery cell may include, but are not limited to, at least one of the following: the gluing position meets the preset second position requirement, the film release paper is completely peeled off, etc. During implementation, the large surface gluing detection mechanism can be used to detect the position of the film pasted on the large surface of the battery cell and / or the peeling state of the release paper to obtain the second gluing detection result. Among them, when it is detected that the position of the film pasted on the large surface of at least one battery cell in the battery cell pair does not meet the preset second position requirement, or the release paper of the film pasted on the large surface of at least one battery cell in the battery cell pair is not completely peeled off, it can be determined that the second gluing detection result of the battery cell pair is that the large surface gluing does not meet the process requirements, that is, the large surface gluing of the battery cell pair is abnormal.

[0115] The second position requirement may be predetermined by those skilled in the art according to the actual production process, and the embodiments of the present disclosure are not limited thereto.

[0116] In some embodiments, Figure 3 As shown, the second position requirement that needs to be met by the adhesive on the large surface of the battery cell may include that the distance d2 between the upper edge of the second film 140 pasted on the large surface 130 of the battery cell and the top patch of the battery cell is within the preset second distance range, the distance d3 between the lower edge of the second film 140 and the bottom of the battery cell is within the second distance range, and the distance d4 between the side edge of the second film 140 and the side edge of the large surface 130 of the battery cell is within the preset third distance range. Among them, the second distance range and the third distance range can be appropriate values ​​set by those skilled in the art according to actual conditions, and the embodiments of the present disclosure are not limited to this. For example, the second distance range can be 0 to 3 millimeters (mm), and the third distance range can be R-1 to R+3mm, where R is the size of the fillet on both sides of the large surface of the battery cell, and R is not less than 1mm.

[0117] The large-surface glue detection mechanism can use any suitable method to perform glue detection on the cell pair after large-surface glue is applied, and the embodiments of the present disclosure are not limited to this. For example, the large-surface glue detection mechanism can include a CCD camera, and the CCD camera is used to take a picture of the large surface of at least one cell in the cell pair to obtain an image of the large surface of at least one cell in the cell pair, and the position of the film and / or the peeling state of the release paper in the image can be identified to obtain the second glue detection result.

[0118] In some embodiments, when the second glue testing result indicates that the large-surface glueing of the battery cell pair is abnormal, the first controller may determine the battery cell pair as a failed battery cell, and control the battery cell conveying mechanism of the large-surface glueing station to flow the battery cell tray carrying the failed battery cell out of the production line from the abnormal discharge port of the large-surface glueing station; after the failed battery cell is manually removed, the battery cell conveying mechanism may return the empty battery cell tray to the production line.

[0119] In some embodiments, a preset cache position in the large-surface gluing station caches a pair of cells with normal large-surface gluing for replacement. After detecting that the large-surface gluing of a cell pair is abnormal, the first controller can control the grabbing mechanism in the large-surface gluing station to grab the cell pair with abnormal large-surface gluing from the cell pair tray to the first placement table for placing abnormal cell pairs, and grab the cell pair with normal large-surface gluing cached in the preset cache position to the cell pair tray, and update the cell data (such as cell code, etc.) in the radio frequency identification (RFID) tag of the cell pair tray. In addition, after the cell pair that subsequently flows into the large-surface gluing station is detected as having normal large-surface gluing, the first controller can control the grabbing mechanism to grab the cell pair with normal large-surface gluing to the preset cache position to supplement the cached cell pair for replacement.

[0120] In the above embodiment, when abnormal adhesive bonding on the large surface of a battery cell pair is detected, the corresponding battery cell pair can be regarded as failed batteries, and new batteries equal to the number of failed batteries can be automatically replenished at the battery cell feeding mechanism, thereby reducing the impact of the abnormal adhesive bonding on the large surface of the battery cell on the battery production process.

[0121] In some embodiments, the failed battery product includes a failed module; the above step S102 may include the following step S141:

[0122] Step S141: The first controller sends the first battery cell quantity and the module type of the failed module to the first host computer.

[0123] The method may further include the following step S142:

[0124] Step S142: the first host computer inserts a new module into the current queue of modules to be assembled in the battery module section based on the module type of the failed module, wherein the module type of the new module is the same as the module type of the failed module.

[0125] It is understandable that in the battery module section, the first host computer can determine the order of assembling modules of different module types according to the work order, and arrange to assemble modules of at least one module type in this order starting from the small unit grouping station, so as to determine the current queue of modules to be assembled. In the case where the first controller detects a failed module, the first host computer can insert a new module of the same module type as the failed module into the current queue of modules to be assembled according to the module type of the failed module, that is, insert a new module to be assembled as a supplement to the failed module.

[0126] In some embodiments, the module type may include a single-row module or a double-row module. Figure 4 As shown, the single-row module 310 includes a plurality of cells 311 arranged opposite to each other with their large surfaces (not shown in the figure), and the side surface 311a of each cell 311 is exposed. Figure 5 As shown, the double-row module 320 includes two parallel rows of battery cells 311, and the multiple battery cells 311 in each row of battery cells 311 are adjacent to each other on large surfaces (not shown in the figure), and the two rows of battery cells 311 are aligned one by one in a side-to-side manner, and every two aligned battery cells 311 are bonded together by a film attached to the side.

[0127] In the above embodiment, when a failed module is generated during the battery production process, on the one hand, it is possible to automatically replenish materials from the battery cell feeding mechanism for supplementing and assembling new modules, and on the other hand, the first host computer inserts a new module of the same module type as the failed module into the current queue of modules to be assembled in the battery module section based on the module type of the failed module. In this way, by replenishing materials from the battery cell feeding mechanism for supplementing and assembling new modules and adjusting the current queue of modules to be assembled in the battery module section, it is possible to achieve automatic replenishment and assembly of modules without stopping the line, reduce manual intervention, and improve production efficiency.

[0128] In some embodiments, the above step S142 may include: the first host computer inserts the newly added module into the head of the queue of modules to be assembled.

[0129] In the above embodiment, after the currently assembled module is completed, a new module of the same type as the failed module can be preferentially inserted into the queue for supplementary assembly, thereby reducing the impact of module failure on the battery production process.

[0130] In some embodiments, the battery module section includes a module pressurizing station. The above step S111 may include the following steps S151 to S152:

[0131] Step S151, the first controller controls the pressurization detection mechanism to detect the status information corresponding to the pressurized module in the module pressurization station to obtain a pressurization detection result; the status information includes the pressurization pressure and / or the module size.

[0132] In step S152 , the first controller determines the module as a failed module in response to the pressurization detection result indicating that the status information of the module is abnormal, and determines the first number of battery cells based on the module type of the failed module.

[0133] The module pressurizing mechanism in the module pressurizing station can pressurize the module formed by stacking battery cells according to the preset pressure and module size, so that the size of the module after pressurization meets the process requirements.

[0134] The pressurization detection mechanism can be used to detect the pressurization pressure and / or module size and other status information corresponding to the pressurized module, so as to determine whether there is any abnormality in the pressurization process of the module. For example, when it is detected that the pressurization pressure of the module is insufficient or exceeds the limit, it can be determined that the pressurization detection result is that the status information of the module is abnormal. For another example, when it is detected that the size of the module after pressurization exceeds the limit, it can be determined that the pressurization detection result is that the status information of the module is abnormal.

[0135] In some embodiments, when the first controller determines that the pressurization detection result indicates that the status information of the module is abnormal, the first controller can write the pressurization detection result into the RFID tag of the module pallet used to carry the module, and control the module conveying mechanism of the module pressurization station to flow the module pallet carrying the module out of the production line from the abnormal discharge port of the module pressurization station; after the failed module is manually removed, the module conveying mechanism can return the empty module pallet to the production line.

[0136] In the above embodiment, when it is detected that the status information corresponding to the pressurized module is abnormal, the module can be regarded as a failed module, and the battery cell feeding mechanism can automatically replenish the battery cells of the first number corresponding to the module type of the failed module, thereby reducing the impact of the abnormality of the pressurized module on the battery production process.

[0137] In some embodiments, the battery module section includes a module code scanning station. The above step S111 may include the following steps S161 to S164:

[0138] Step S161: the first controller controls the module code scanning detection mechanism to scan each battery cell in the module in the module code scanning station to obtain a first battery cell code of each battery cell in the module.

[0139] Step S162: the first controller obtains a second cell code set corresponding to the module recorded during the assembly process of the module.

[0140] In some embodiments, the first controller may record the cell code of each cell stacked into the module in an RFID tag of a module tray for carrying the module, or in a preset register or memory of the first controller before stacking the cells into the module.

[0141] Step S163: the first controller uses the second battery cell code set to verify the first battery cell code of each battery cell in the module to obtain a scan verification result.

[0142] In some embodiments, when the first cell code of each cell in the module matches each second cell code in the second cell code set one by one, it can be determined that the scanning verification result indicates that the cell code of each cell in the module is normal; when the first cell code of each cell in the module does not match each second cell code in the second cell code set one by one, it can be determined that the scanning verification result indicates that the cell code indicating one cell in the module is abnormal.

[0143] In step S164, the first controller determines the module as a failed module in response to the code scanning verification result indicating that the cell code of at least one cell in the module is abnormal, and determines the first cell quantity based on the module type of the failed module.

[0144] It is understandable that the number of cells required to assemble modules of different module types may be different, that is, the number of first cells corresponding to modules of different module types may be different. During implementation, the number of first cells corresponding to at least one module type may be predetermined, so that based on the module type of the failed module, the number of first cells corresponding to the failed module may be determined.

[0145] In some embodiments, when the first controller determines that the scan code verification result indicates that the cell code of at least one cell in the module is abnormal, the scan code verification result can be written into the RFID tag of the module tray carrying the module, and the module conveying mechanism of the module scanning station can be controlled to flow the module tray carrying the module out of the production line from the abnormal discharge port of the module scanning station; after the failed module is manually removed, the module conveying mechanism can return the empty module tray to the production line.

[0146] In the above embodiment, when it is detected that the cell code of at least one cell in the module is abnormal, the module can be treated as a failed module, and the cell feeding mechanism can automatically replenish the first number of cells corresponding to the module type of the failed module, thereby reducing the impact of the abnormal cell code of at least one cell in the module on the battery production process.

[0147] In some embodiments, the battery module section includes an insulation withstand voltage testing station. The above step S111 may include the following steps S171 to S172:

[0148] Step S171: the first controller controls the insulation and voltage withstand testing mechanism to perform insulation and voltage withstand testing on the module in the insulation and voltage withstand testing station to obtain the insulation testing result of the module.

[0149] Step S172: In response to the insulation detection result indicating poor insulation between battery cells in the module and / or poor insulation between the battery cells and the module housing, the first controller determines the module as a failed module, and determines the first number of battery cells based on the module type of the failed module.

[0150] In some embodiments, when the first controller determines that the insulation test result of the module indicates poor insulation between the battery cells in the module and / or poor insulation between the battery cells and the module housing, the first controller can write the insulation test result into the RFID tag of the module tray carrying the module, and control the module conveying mechanism of the insulation and voltage resistance testing station to flow the module tray carrying the module out of the production line from the abnormal discharge port of the insulation and voltage resistance testing station; after the failed module is manually removed, the module conveying mechanism can return the empty module tray to the production line.

[0151] In the above embodiments, when poor insulation between battery cells in the module and / or poor insulation between battery cells and the module casing is detected, the module can be treated as a failed module, and a first number of battery cells corresponding to the module type of the failed module can be automatically replenished at the battery feeding mechanism, thereby reducing the impact of poor insulation between battery cells in the module and / or poor insulation between battery cells and the module casing on the battery production process.

[0152] In some embodiments, the battery production line includes a battery pack section, the first section is the battery module section, and the failed battery product includes a failed battery pack. The above step S101 may include the following step S181:

[0153] Step S181: In response to detecting that a failed battery pack is generated in the process flow of the battery pack section, the second controller of the battery pack section determines the number of second battery cells corresponding to the failed battery pack.

[0154] The above step S103 may include the following step S182:

[0155] Step S182: In response to receiving the second number of battery cells, the second host computer of the battery pack section controls the battery cell feeding mechanism in the battery module section to supplement the feeding of the second number of battery cells.

[0156] The battery pack section refers to the section in the battery production process used to produce battery packs. The battery pack section may include multiple workstations, and multiple modules can be assembled into a battery pack after being processed by each workstation in the battery pack section.

[0157] During implementation, the workstations included in the battery pack section may be determined based on actual production requirements, which is not limited in the embodiments of the present disclosure.

[0158] In some embodiments, the battery pack section may include but is not limited to at least one of a lower box body gluing station, a module box entry station, a module tightening station, a pole addressing station, a welding station, and a post-weld inspection station. The lower box body gluing station can be used to apply glue to the lower box of the battery pack to be assembled. The module box entry station can be used to stack the modules into the lower box after gluing. The module tightening station can be used to tighten the connection structure between each module stacked in the lower box and the lower box to fix each module in the lower box in the lower box. The pole addressing station is used to address the poles of each module fixed in the lower box to determine the addressing coordinates of each pole in the module. The welding station can be used to weld the poles in the module according to the addressing coordinates of each pole in the module to electrically connect at least two battery cells in the module through a busbar. The post-weld inspection station can be used to inspect the welded module to determine whether the welded module meets the process requirements. It is understandable that a failed battery pack may be produced in any station in the battery pack section.

[0159] Figure 6 A schematic diagram of the structure of a lower box after glue coating in a battery production process provided by an embodiment of the present disclosure, such as Figure 6 As shown, glue 411 for adhering the module can be applied to the lower box 410 of the battery pack to be assembled.

[0160] Figure 7 A schematic diagram of stacking modules into a lower box during a battery production process provided by an embodiment of the present disclosure, such as Figure 7 As shown, the modules 420 can be stacked and loaded into the lower box 410 in the module box loading station.

[0161] Figure 8 A schematic diagram of the structure of a welded module provided in an embodiment of the present disclosure is shown in FIG. Figure 8 As shown, a busbar 430 may be installed on the module in the lower box 410 , and the cell poles 421 in the module may be welded to the busbar 430 , so that at least two cells in the module may be electrically connected through the busbar 430 .

[0162] The second controller of the battery pack section can be used to control the mechanisms in each workstation in the battery pack section so that the mechanisms in each workstation cooperate to realize the assembly of the battery pack. In addition, the second controller can also use the mechanisms in the workstation to detect whether a failed battery pack is generated in the process flow of the battery pack section. It is understandable that the battery pack included in the process flow of the battery pack section can be a semi-finished battery pack or a finished battery pack, and the embodiments of the present disclosure are not limited to this.

[0163] In some embodiments, the second controller may refer to a lower computer in the battery pack section, such as an industrial computer, a PLC, etc. It should be noted that the second controller may be a separate controller that can perform overall control of the mechanisms in each station in the battery pack section; the second controller may also include multiple second sub-controllers, each of which can control a mechanism in the battery pack section, and the embodiments of the present disclosure are not limited to this.

[0164] The second number of battery cells corresponding to the failed battery pack refers to the number of battery cells required to assemble the failed battery pack. After determining the second number of battery cells, the second controller can send the second number of battery cells to the second host computer of the battery module section. After receiving the second number of battery cells, the second host computer can control the battery cell feeding mechanism in the battery module section to supplement the feeding of the second number of battery cells. In this way, the production equipment in the battery production line can supplement the production of new battery packs corresponding to the failed battery pack.

[0165] In some embodiments, the number of second battery cells corresponding to the failed battery pack can be determined by scanning the number of poles in the modules installed in the lower box of the failed battery pack.

[0166] In some embodiments, the number of second battery cells corresponding to the failed battery pack may be determined according to the pack information of the failed battery pack.

[0167] The package information of the battery pack may include, but is not limited to, the package number of the battery pack, the number of modules in the battery pack, the module type of each module, and / or the number of cells contained in each module.

[0168] In some embodiments, the package information of the failed battery pack may carry the second number of battery cells corresponding to the failed battery pack. The second controller may send the package information of the failed battery pack to the second host computer. The second host computer may control the battery cell loading mechanism in the battery module section to supplement the loading of the second number of battery cells based on the package information.

[0169] It is understandable that the second host computer can be a host computer for controlling the process flow of assembling the battery pack in the battery pack section. In implementation, the second host computer can be at least one of a server, a laptop, a tablet computer, a desktop computer, a smart phone, etc.

[0170] In this way, when a failed battery pack is generated in the process flow of the battery pack section, the battery cell feeding mechanism can be automatically replenished without stopping the line to re-produce a new battery pack corresponding to the failed battery pack, thereby reducing manual intervention and improving production efficiency.

[0171] In some embodiments, the above step S182 may include the following steps S191 to S193:

[0172] Step S191, in response to receiving the second battery cell quantity, the second host computer reports the second battery cell quantity to the production execution system;

[0173] Step S192, the production execution system adds a module assembly work order based on the second battery cell quantity, and sends the newly added module assembly work order to the first host computer of the battery module section;

[0174] Step S193, the first host computer controls the battery cell loading mechanism to supplement the loading of the second number of battery cells based on the module assembly work order, so that the production equipment in the battery cell production line supplements the production of new battery packs corresponding to the failed battery pack based on the second number of battery cells supplemented.

[0175] The Manufacturing Execution System (MES) can be used to manage and control module assembly work orders in the battery module section.

[0176] In some embodiments, the package information of the failed battery pack may carry the number of second battery cells corresponding to the failed battery pack. The second controller may send the package information of the failed battery pack to the production execution system through the second host computer. The production execution system may add a module assembly work order based on the package information of the failed battery pack.

[0177] In some embodiments, the production execution system can determine the second battery cell number, the number of modules required to produce a qualified battery pack corresponding to the failed battery pack, and the module type of each module based on the package information of the failed battery pack reported by the second host computer, and add at least one module assembly work order according to the determined second battery cell number, the number of modules, and the module type of each module. The production execution system can issue the at least one newly added module assembly work order to the first host computer of the battery module section, so that the first host computer controls the various mechanisms in the battery module section through the first controller to produce at least one module for supplementing and assembling a new battery pack in the battery pack section to replace the failed battery pack.

[0178] In the disclosed embodiment, when a failed battery pack is generated in the process flow of the battery pack section, the second controller of the battery pack section reports the second number of cells corresponding to the failed battery pack to the production execution system through the second host computer of the battery pack section. The production execution system can add a module assembly work order based on the package information of the failed battery pack, and send the newly added module assembly work order to the first host computer of the battery module section, so that the first host computer controls the cell feeding mechanism to replenish the cells of the second number of cells based on the module assembly work order. Thus, it is possible to automatically start feeding from the cell feeding mechanism without stopping the line to re-produce a new battery pack corresponding to the failed battery pack, reduce manual intervention, and improve production efficiency.

[0179] In some embodiments, the above step S181 may include the following steps S1011 to S1013:

[0180] In step S1011, in response to detecting an abnormality in a battery pack in the process flow of the battery pack section, the second controller controls the transportation equipment carrying the battery pack to transport the battery pack from the current workstation to a maintenance buffer area, and adds the package information of the battery pack to a preset list of battery packs to be repaired.

[0181] Step S1012, in response to the maintenance completion confirmation operation for the battery pack, the second controller controls the transportation equipment to transport the battery pack from the maintenance buffer area to the current workstation, and clears the package information of the battery pack in the list of battery packs to be repaired.

[0182] Step S1013: In response to the maintenance failure confirmation operation for the battery pack, the second controller determines the battery pack as a failed battery pack, and determines the number of battery cells required to assemble the failed battery pack as a second number of battery cells corresponding to the failed battery pack.

[0183] It is understandable that since there are many manual operation stations in the battery pack section, there may be many abnormalities that require manual inspection, so the abnormal battery packs can be transported to the maintenance buffer area for manual repair.

[0184] In some embodiments, an automated guided vehicle (AGV) may be used as a transport device in a battery pack section to transport a single battery pack, thereby increasing the production flexibility of the battery pack.

[0185] For example, after the second controller detects that the battery pack is abnormal, it can control the AGV used to transport the battery pack to pull the battery pack out of the production line separately. The user can use a handheld barcode scanner to read the package information of the battery pack (such as the package number). After the second controller obtains the package information of the battery pack, it can add the package information to the preset list of battery packs to be repaired. If the manual repair is completed, the AGV can carry the repaired battery pack back to the production line to continue production; the user can use a handheld barcode scanner to read the package information of the repaired battery pack again as a confirmation operation for the completion of the repair of the battery pack. If the manual repair fails, the user can confirm the failure of the repair and determine the battery pack as a failed battery pack.

[0186] In the above embodiment, a maintenance cache area is set up, and after the battery pack detected to have an abnormality is transported to the maintenance cache area, on the one hand, when the maintenance is completed, a maintenance completion confirmation operation can be performed to trigger the second controller to control the transportation equipment to transport the battery pack from the maintenance cache area back to the production line, and the package information of the battery pack can be cleared from the list of battery packs to be repaired, so that the battery pack after the maintenance is completed can continue to return to the production line, thereby reducing the waste of material costs and process costs; on the other hand, when the maintenance fails, a maintenance failure confirmation operation can be performed to trigger the second controller to determine the battery pack as a failed battery pack, and report the second battery cell number corresponding to the failed battery pack to the second host computer, so that it is possible to automatically start replenishing materials from the battery cell loading mechanism without stopping the line, so as to re-produce a new battery pack corresponding to the failed battery pack.

[0187] The present disclosure provides a battery production control system. Fig. 9 As shown, the battery generation control system 500 includes: a controller 510 and a host computer 520; wherein:

[0188] The controller 510 is applied to any section in the battery production line, and is used to: in response to detecting that a failed battery product is generated in the process flow of the section, determine the number of battery cells corresponding to the failed battery product; and send the number of battery cells to the host computer 520;

[0189] The upper computer 520 is applied to the work section and is used to: in response to receiving the number of battery cells, control the battery cell feeding mechanism in the first work section of the battery production line to supplement the battery cells of the number of battery cells.

[0190] In the disclosed embodiment, the controller of any section in the battery production line determines the number of cells corresponding to the failed battery product in response to detecting that a failed battery product is generated in the process flow of the section, and sends the number of cells to the host computer of the section. In response to receiving the number of cells, the host computer controls the cell feeding mechanism in the first section of the battery production line to replenish the number of cells. In this way, when a failed battery product is generated during the battery production process, the cell feeding can be automatically performed from the beginning of the battery production line without stopping the line, reducing manual intervention and improving production efficiency.

[0191] In some embodiments, the battery production line includes a battery module section, and the first section is the battery module section. Fig.10 As shown, the controller 510 includes a first controller 511 of the battery module section, and the host computer 520 includes a first host computer 521 of the battery module section; wherein:

[0192] The first controller 511 is used to: in response to detecting that a failed battery product is generated in the process flow of the battery module section, determine the first number of battery cells corresponding to the failed battery product; the failed battery product includes a failed battery cell and / or a failed module; and send the first number of battery cells to the first host computer 521;

[0193] The first host computer 521 is used for: in response to receiving the first number of battery cells, controlling the battery cell feeding mechanism in the battery module section to supplement the battery cells of the first number of battery cells.

[0194] In this way, when failed cells and / or failed modules are generated during the battery production process, the cells can be automatically replenished without stopping the production line, thereby reducing manual intervention and improving production efficiency.

[0195] In some embodiments, the failed battery product includes a failed battery cell, and the battery module section includes a side gluing station; the first controller 511 is also used to: control the side gluing detection mechanism to perform a gluing detection on the battery cell after side gluing in the side gluing station to obtain a first gluing detection result; in response to the first gluing detection result indicating that the side gluing of the battery cell is abnormal, determine the battery cell as a failed battery cell, and determine the number of the failed batteries as the first number of batteries.

[0196] In this way, when abnormal glue sticking on the side of the battery cell is detected, the battery cell can be regarded as a failed battery cell, and new battery cells equal to the number of failed batteries can be automatically replenished at the battery cell feeding mechanism, thereby reducing the impact of the abnormal glue sticking on the side of the battery cell on the battery production process.

[0197] In some embodiments, the failed battery product includes failed battery cells, and the battery module section includes a large-surface gluing station; the first controller 511 is also used to: control the large-surface gluing detection mechanism to perform gluing detection on the battery cell pairs after large-surface gluing in the large-surface gluing station to obtain a second gluing detection result; in response to the second gluing detection result characterizing that the large-surface gluing of the battery cell pair is abnormal, each battery cell in the battery cell pair is determined to be a failed battery cell, and the number of the failed battery cells is determined to be the first number of battery cells.

[0198] In this way, when an abnormality in the adhesive bonding of the large surface of a battery cell pair is detected, the corresponding battery cell pair can be regarded as failed batteries, and new batteries equal to the number of failed batteries can be automatically replenished at the battery cell feeding mechanism, thereby reducing the impact of the abnormality in the adhesive bonding of the large surface of the battery cell on the battery production process.

[0199] In some embodiments, the failed battery product includes a failed module.

[0200] The first controller 511 is further used to: send the first battery cell quantity and the module type of the failed module to the first host computer 520;

[0201] The first host computer 521 is further used to: based on the module type of the failed module, insert a new module into the current queue of modules to be assembled in the battery module section, wherein the module type of the new module is the same as the module type of the failed module.

[0202] In this way, when a failed module is generated during the battery production process, on the one hand, it can automatically replenish materials from the battery cell feeding mechanism for supplementing and assembling new modules, and on the other hand, the first host computer inserts a new module of the same module type as the failed module into the current queue of modules to be assembled in the battery module section based on the module type of the failed module. Therefore, by replenishing materials from the battery cell feeding mechanism for supplementing and assembling new modules and adjusting the current queue of modules to be assembled in the battery module section, it is possible to achieve automatic replenishment and assembly of modules without stopping the line, reduce manual intervention, and improve production efficiency.

[0203] In some embodiments, the first host computer 521 is further used to: insert a new module into the head of the queue of modules to be assembled.

[0204] In this way, after the currently assembled module is completed, a new module of the same type as the failed module can be added to the queue for supplementary assembly, thereby reducing the impact of module failure on the battery production process.

[0205] In some embodiments, the battery module section includes a module pressurizing station; the first controller 511 is also used to: control the pressurizing detection mechanism to detect the status information corresponding to the module after pressurization in the module pressurizing station to obtain the pressurizing detection result; the status information includes the pressurizing pressure and / or the module size; in response to the pressurizing detection result indicating that the status information of the module is abnormal, the module is determined to be a failed module, and the first battery cell quantity is determined based on the module type of the failed module.

[0206] In this way, when it is detected that the status information corresponding to the pressurized module is abnormal, the module can be treated as a failed module, and the battery cell feeding mechanism can automatically replenish the battery cells of the first number corresponding to the module type of the failed module, thereby reducing the impact of the abnormality of the pressurized module on the battery production process.

[0207] In some embodiments, the battery module section includes a module scanning station; the first controller 511 is also used to: control the module scanning detection mechanism to scan each battery cell in the module in the module scanning station to obtain a first battery cell code of each battery cell in the module; obtain a second battery cell code set corresponding to the module recorded during the assembly process of the module; use the second battery cell code set to verify the first battery cell code of each battery cell in the module to obtain a scanning verification result; in response to the scanning verification result indicating that the battery cell code of at least one battery cell in the module is abnormal, determine the module as a failed module, and determine the first battery cell quantity based on the module type of the failed module.

[0208] In this way, when it is detected that the cell code of at least one cell in the module is abnormal, the module can be treated as a failed module, and the cell feeding mechanism can automatically replenish the first number of cells corresponding to the module type of the failed module, thereby reducing the impact of the abnormal cell code of at least one cell in the module on the battery production process.

[0209] In some embodiments, the battery module section includes an insulation and voltage withstand testing station; the first controller 511 is also used to: control the insulation and voltage withstand testing mechanism to perform insulation and voltage withstand testing on the module in the insulation and voltage withstand testing station to obtain the insulation testing result of the module; in response to the insulation testing result characterizing poor insulation between battery cells in the module and / or poor insulation between the battery cells and the module casing, determine the module as a failed module, and determine the first battery cell quantity based on the module type of the failed module.

[0210] In this way, when poor insulation between battery cells in the module and / or poor insulation between battery cells and the module casing is detected, the module can be treated as a failed module, and the battery cell feeding mechanism can automatically replenish the battery cells of the first number corresponding to the module type of the failed module, thereby reducing the impact of poor insulation between battery cells in the module and / or poor insulation between battery cells and the module casing on the battery production process.

[0211] In some embodiments, the battery production line includes a battery pack section, the first section is a battery module section, and the failed battery products include failed battery packs, such as Fig.11 As shown, the controller 510 includes a second controller 512 of the battery pack section, and the host computer 520 includes a second host computer 522 of the battery pack section;

[0212] The second controller 512 is used to: in response to detecting that a failed battery pack is generated in the process flow of the battery pack section, determine the second number of battery cells corresponding to the failed battery pack; and send the second number of battery cells to the second host computer 522;

[0213] The second host computer 522 is used for: in response to receiving the second number of battery cells, controlling the battery cell feeding mechanism in the battery module section to supplement the feeding of the second number of battery cells.

[0214] In this way, when a failed battery pack is generated in the process flow of the battery pack section, the battery cell feeding mechanism can be automatically replenished without stopping the line to re-produce a new battery pack corresponding to the failed battery pack, thereby reducing manual intervention and improving production efficiency.

[0215] In some embodiments, Fig.12 As shown, the production control system 500 further includes: a production execution system 530, and the host computer 520 further includes a first host computer 521 in the battery module section;

[0216] The second host computer 522 is further configured to: in response to receiving the second battery cell quantity, report the second battery cell quantity to the production execution system 530;

[0219] In this way, when a failed battery pack is generated in the process flow of the battery pack section, the second controller of the battery pack section reports the second number of cells corresponding to the failed battery pack to the production execution system through the second host computer of the battery pack section. The production execution system can add a module assembly work order based on the package information of the failed battery pack, and send the newly added module assembly work order to the first host computer, so that the first host computer controls the cell feeding mechanism to replenish the cells of the second number of cells based on the module assembly work order. In this way, it is possible to automatically start replenishing materials from the cell feeding mechanism without stopping the line to re-produce a new battery pack corresponding to the failed battery pack, reduce manual intervention, and improve production efficiency.
