Description

Technical Field

[0001] The present application relates to the field of industrial manufacturing technology, and in particular to a battery appearance inspection system and method. Background Art

[0002] During the battery production process, a testing machine is required to perform appearance inspection on the batteries. Due to the limitations of the testing machine's detection algorithm and technical capabilities, some batteries with no appearance problems may be mistakenly judged as having appearance problems, resulting in over-killing of the batteries. Alternatively, some batteries with appearance problems may be mistakenly judged as having no appearance problems, resulting in missed killing of the batteries.

[0003] Therefore, visual inspection is introduced to re-evaluate the appearance of over-killed materials or missed materials. However, the efficiency and accuracy of visual inspection are low. Summary of the Invention

[0004] This application at least provides a battery appearance detection system and method.

[0005] In a first aspect, the present application provides a battery appearance inspection system, which includes a sorting system, a visual inspection system, a re-judgment cloud system and a re-judgment edge system; the visual inspection system is used to perform appearance inspection on batteries passing through a logistics line, and obtain a first inspection result of each battery based on the marking information of each battery, wherein the visual inspection system is located upstream of the logistics line; the re-judgment cloud system, in response to the first inspection result of the battery meeting the re-judgment condition, instructs the re-judgment edge system to perform appearance re-judgment on the battery based on the battery appearance information provided by the visual inspection system, and obtain a second inspection result of the battery; the sorting system is used to transport the battery to a sorting point in response to the logistics line, and obtain the latest appearance inspection result of the battery, wherein the sorting point is located downstream of the logistics line, and when the second inspection result of the battery does not currently exist, the latest appearance inspection result of the battery is the first inspection result, and when the second inspection result of the battery currently exists, the latest appearance inspection result of the battery is the second inspection result, and the battery is sorted based on the latest appearance inspection result of the battery. The situation where the second inspection result of the battery does not currently exist includes that the first inspection result of the battery meets the re-judgment condition and the second inspection result of the battery is not generated when the logistics line transports the battery to the sorting point.

[0006] Therefore, during the transportation of batteries along the logistics line, they first pass through a visual inspection system located upstream of the logistics line. This visual inspection system performs a visual inspection on the batteries and obtains a first inspection result. After passing the visual inspection system upstream of the logistics line, the logistics line continues to transport the batteries to a sorting point located downstream of the logistics line. Meanwhile, the re-evaluation cloud system is responsible for instructing the re-evaluation edge system to conduct a visual re-evaluation of the batteries if the first inspection result meets the re-evaluation conditions. Therefore, during the process of transporting batteries on the logistics line, the appearance of the batteries whose first test results meet the re-judgment conditions is re-judged, and the appearance re-judgment and transportation actions of the batteries whose first test results meet the re-judgment conditions are carried out in parallel, that is, the logistics line continuously transports the batteries whose first test results meet the re-judgment conditions, and the appearance re-judgment of the batteries whose first test results meet the re-judgment conditions will not affect the rhythm of their transportation by the logistics line; therefore, the appearance re-judgment of the batteries can be achieved without affecting the battery transportation rhythm, meeting the high-rhythm production requirements of the production line, that is, the accuracy of battery appearance inspection can be improved to a certain extent without affecting the battery transportation rhythm, and the occurrence of misjudgment of battery appearance inspection can be reduced.

[0007] Among them, the battery appearance inspection system also includes a production execution system, which is communicated with the visual inspection system, the re-judgment cloud system and the sorting system. The production execution system is used to record the latest appearance inspection results of the battery based on the inspection results sent by the visual inspection system or the re-judgment cloud system, and to feedback the latest appearance inspection results of the battery to the sorting system.

[0008] Therefore, the latest appearance inspection results of the battery can be recorded and fed back through the production execution system.

[0009] Among them, the production execution system is used to receive the first detection information sent by the visual inspection system, the first detection information includes the marking information of the battery and the first detection result of the battery, and save the first detection result as the latest appearance detection result of the battery corresponding to the marking information; receive the second detection information sent by the re-judgment cloud system, the second detection information includes the marking information of the battery and the second detection result of the battery, and use the second detection information to update the latest appearance detection result of the battery; and receive the marking information sent by the sorting system as the mark to be queried, and feedback the latest appearance detection result of the battery corresponding to the mark to be queried to the sorting system.

[0010] Therefore, the latest appearance inspection results of the battery can be recorded, updated and fed back through the production execution system.

[0011] Among them, the re-judgment cloud system is also used to send second detection information when it is determined that the preset conditions are currently met, wherein the preset conditions include at least one of the following: the sorting system is not currently sorting the battery, and the second detection result of the battery is inconsistent with the first detection result of the battery; and / or the re-judgment condition is: the first detection result is that the battery is in the target appearance state; the production execution system executes to save the first detection result as the latest appearance detection result of the battery corresponding to the marking information, including: recording the marking information of the battery, and setting the target appearance state mark for the marking information of the battery; the production execution system executes to update the latest appearance detection result of the battery using the second detection information, including: in response to the second detection result of the battery being that the battery is not in the target appearance state, releasing the target appearance state mark of the marking information of the battery; the sorting system is also used to query the production execution system whether the target appearance state mark is currently set for the mark to be queried, so as to determine the latest appearance detection result of the battery corresponding to the mark to be queried.

[0012] Therefore, the second test result of the battery is inconsistent with the first test result of the battery, indicating that the first test result of the battery is incorrect. Then, the latest appearance test result of the battery currently saved by the production execution system - the first test result of the battery is incorrect. The latest appearance test result of the battery currently saved by the production execution system - the first test result of the battery cannot truly reflect the appearance of the battery. Since the sorting system sorts the batteries based on the latest appearance test result of the battery saved by the production execution system, whether the latest appearance test result of the battery currently saved by the production execution system is updated or not will affect the sorting of the batteries by the sorting system. If the sorting system is not currently sorting the batteries, whether the latest appearance test result of the battery currently saved by the production execution system is updated or not will affect the sorting of the batteries by the sorting system. At this time, the latest appearance inspection result of the battery saved in the production execution system will be updated, and the latest appearance inspection result of the battery will be updated to the second inspection result of the battery, so that the latest appearance inspection result of the battery saved in the production execution system can accurately reflect the actual appearance of the battery. Then, when the sorting system sorts the battery, the production execution system can feedback the latest appearance inspection result reflecting the actual appearance of the battery to the sorting system, so that the sorting system can accurately sort the battery based on the latest appearance inspection result of the battery.

[0013] A target appearance state flag is set for the tag information to assign a classification identifier that reflects the battery's appearance. This reduces memory consumption compared to recording the first test result of the battery corresponding to the tag information. Furthermore, if the battery is re-determined not to be in the target appearance state, the target appearance state flag set in the tag information is simply removed. Furthermore, when the sorting system sorts batteries, it can determine the battery's latest appearance test result by determining whether the target appearance state flag is currently set in the battery's tag information. This enables faster response times for the sorting system and improves battery sorting efficiency.

[0014] Among them, the production execution system is also used to respond to the sorting system to perform sorting of the batteries, and record the sorting status of the batteries as sorted; and / or, the production execution system is also used to detect that the batteries in the battery container are taken out, record the container identification of the battery container, and remind the sorting system, wherein the battery container is used to accommodate the batteries sorted by the sorting system; and / or, the visual inspection system corresponds to the inspection station provided on the logistics line, the visual inspection system includes a first battery identification device, the first battery identification device is located at the feed position of the inspection station, and is used to identify the marking information of the batteries transported by the logistics line, and the visual inspection system is also used to respond to the first battery identification device identifying the marking information of the battery, and send the marking information identified by the first battery identification device to the production execution system; and / or, the visual inspection system corresponds to the inspection station provided on the logistics line, the visual inspection system includes a second battery identification device, the second battery identification device is located at the discharge position of the inspection station, and is used to identify the marking information of the batteries transported by the logistics line, and the visual inspection system is also used to respond to the second battery identification device identifying the marking information of the battery, and send the marking information of the battery identified by the second battery identification device and the first inspection result of the battery to the production execution system.

[0015] Therefore, the production execution system can also record the sorting status of the batteries.

[0016] After the battery is transported to the feed position of the inspection station by the logistics line, the appearance inspection of the battery begins. That is, after the battery is transported to the feed position of the inspection station by the logistics line, the state of the battery changes (enters the appearance inspection state). Since the first battery identification device is located at the feed position of the inspection station, the battery state change can be fed back to the production execution system as soon as the battery state changes.

[0017] After the battery is transported to the discharge position of the inspection station by the logistics line, the status of the battery changes (the appearance inspection status is completed). Since the second battery identification device is located at the discharge position of the inspection station, it can feedback the battery status change to the production execution system as soon as the battery status changes.

[0018] Among them, the visual inspection system includes an image acquisition device and at least one battery recognition device. The battery recognition device is used to identify the marking information of batteries transported on the logistics line, and the image acquisition device is used to collect battery images of batteries transported on the logistics line; the visual inspection system is specifically used to use the battery image to perform appearance inspection on the battery to obtain a first inspection result of the battery, and associate the first inspection result of the battery with the corresponding marking information.

[0019] Therefore, since the visual inspection system completes battery image acquisition, battery mark recognition, battery appearance inspection, and association of battery marks with the first inspection result during the process of transporting batteries on the logistics line, a series of battery appearance inspection actions and battery transportation actions are carried out in parallel, that is, the logistics line transports batteries continuously, and a series of battery appearance inspection actions will not affect the rhythm of battery transportation on the logistics line; therefore, the appearance inspection of batteries can be achieved without affecting the battery transportation rhythm, meeting the high-rhythm production requirements of the production line.

[0020] Among them, the visual inspection system corresponds to the inspection station arranged in the logistics line, and the at least one battery identification device includes a first battery identification device and a second battery identification device, and the first battery identification device and the second battery identification device are respectively located at the feeding position and the discharging position of the inspection station; and / or, the image acquisition device and at least one battery identification device are located before the sorting point; and / or, the visual inspection system is specifically used to use the battery image to perform defect detection on the battery, obtain a defect detection result, and obtain a first inspection result of the battery based on the defect detection result, and the first inspection result represents whether the battery is qualified.

[0021] Therefore, the visual inspection system inspects the appearance of the battery before the sorting system sorts the battery, so that the sorting system can sort out the batteries with defects and those without defects, thereby ensuring the consistency of the batteries.

[0022] The defect detection result of the battery image of the battery is used to determine whether there are defects in the appearance of the battery.

[0023] Among them, the visual inspection system is also used to send re-inspection request information about the battery to the re-inspection cloud system when the first inspection result of the battery meets the re-inspection conditions, wherein the re-inspection request information includes the battery marking information, the battery appearance information and the first inspection result, and the battery appearance information includes at least one of the battery image and the location information of the candidate defect area of ​​the battery; the re-inspection cloud system is used to receive the re-inspection request information about the battery sent by the visual inspection system, and generate a re-inspection task for the battery and assign the re-inspection task to the re-inspection edge system, receive the second inspection result of the battery fed back by the re-inspection edge system after executing the re-inspection task, and update the second inspection result of the battery as the latest appearance inspection result of the battery.

[0024] Therefore, the retrial request information and the preset conditions can be flexibly set.

[0025] Among them, the re-judgment cloud system is also used to execute the step of updating the second inspection result of the battery as the latest appearance inspection result of the battery when it is determined that the preset conditions are currently met, wherein the preset conditions include at least one of the following: the sorting system is not currently sorting the battery, and the second inspection result of the battery is inconsistent with the first inspection result of the battery.

[0026] Therefore, the preset condition includes an inconsistency between the second test result of the battery and the first test result of the battery; that is, when the second test result of the battery is inconsistent with the first test result of the battery, the second test result of the battery is updated as the latest appearance test result of the battery. The inconsistency between the second test result of the battery and the first test result of the battery indicates that the first test result of the battery is incorrect. Therefore, the latest appearance test result of the battery, which is the first test result of the battery, is incorrect and cannot truly reflect the appearance of the battery. In this case, the second test result of the battery is updated as the latest appearance test result of the battery, and the latest appearance test result of the battery is updated to the second test result of the battery, so that the latest appearance test result of the battery can accurately reflect the appearance of the battery. If the second test result of the battery is updated as the latest appearance test result of the battery before the logistics line transports the battery to the sorting point, then when the sorting system sorts the battery, it can accurately sort the battery based on the latest appearance test result that reflects the actual appearance of the battery. If the second test result of the battery is updated as the latest appearance test result of the battery after the logistics line transports the battery to the sorting point, the updated appearance test result of the battery facilitates subsequent inquiries by users to determine the actual appearance of the battery, facilitating traceability.

[0027] The preset conditions include that the sorting system is not currently sorting the batteries, that is, when the sorting system is not currently sorting the batteries, the second inspection result of the batteries is updated as the latest appearance inspection result of the batteries. Since the sorting system sorts the batteries based on the latest appearance inspection result of the batteries, whether the latest appearance inspection result of the batteries is updated or not affects the sorting of the batteries by the sorting system. If the sorting system has already sorted the batteries, then whether the latest appearance inspection result of the batteries is updated or not will no longer affect the sorting of the batteries by the sorting system, and there is no need to update the latest appearance inspection result of the batteries. If the sorting system is not currently sorting the batteries, then whether the latest appearance inspection result of the batteries is updated or not will still affect the sorting of the batteries by the sorting system, and the latest appearance inspection result of the batteries will need to be updated.

[0028] Among them, the preset conditions include: the sorting system is not currently sorting the batteries; the battery appearance inspection system also includes a production execution system, which is used to record the sorting status of batteries transported on the logistics line; the re-judgment cloud system is also used to query the production execution system about the current sorting status of the batteries to determine whether the sorting system is currently sorting the batteries.

[0029] Therefore, the sorting status of batteries transported in the flow line can be recorded by the production execution system.

[0030] The current sorting status of the battery can be queried through the production execution system.

[0031] Among them, the battery appearance information includes the battery image of the battery and the location information of the candidate defect area of ​​the battery in the battery image; the re-evaluation cloud system is also used to mark the candidate defect area of ​​the battery image based on the location information of the candidate defect area, and when assigning the re-evaluation task to the re-evaluation edge system, the re-evaluation edge system sends the marked battery image to the re-evaluation edge system; and / or, the re-evaluation edge system includes several re-evaluation edge devices, and the re-evaluation cloud system is also used to assign the battery re-evaluation task to one of the re-evaluation edge devices based on the scheduling algorithm; and / or, the re-evaluation edge system is used to display the battery image of the battery to the re-evaluation personnel, and generate a second detection result of the battery in response to the re-evaluation operation of the re-evaluation personnel.

[0032] Therefore, by marking the candidate defect areas of the battery image, the candidate defect areas in the marked battery image are highlighted, so that when the re-judgment edge system performs appearance re-judgment based on the marked battery image, it can focus on the candidate defect areas in the battery image more quickly and accurately for appearance re-judgment, thereby achieving efficient and accurate appearance re-judgment of the battery.

[0033] The scheduling algorithm is used to allocate the battery re-inspection tasks to the re-inspection edge devices that are idle or have fewer re-inspection tasks, so that the appearance of the battery can be re-inspected in a timely manner.

[0034] Battery image display and interactive operation response enable efficient and accurate appearance review of batteries.

[0035] The battery appearance inspection system further comprises a third battery identification device provided at the sorting point, the third battery identification device being used to identify marking information of batteries passing through the sorting point; the sorting system further comprises a production execution system, the sorting system further comprising a production execution system, the sorting system further comprising a production execution system, the sorting system further comprising a production execution system, the production execution ...

[0036] Therefore, before the sorting system sorts the batteries, it will query the latest appearance inspection results of the batteries currently located at the sorting point based on the battery marking information identified by the third battery identification device located at the sorting point.

[0037] After the sorting system sorts the batteries based on the latest appearance inspection results of the batteries, it sends a battery sorting notification including the battery marking information to the production execution system, and promptly feeds back the battery sorting status to the production execution system.

[0038] The appearance inspection result of the battery is qualified or unqualified; the sorting system performs sorting on the battery based on the latest appearance inspection result of the battery, including: in response to the latest appearance inspection result of the battery being qualified, controlling the logistics line to transport the battery to the qualified battery processing area; in response to the latest appearance inspection result of the battery being unqualified, controlling the logistics line to transport the battery to the unqualified battery processing area.

[0039] Therefore, a qualified battery processing area and an unqualified battery processing area are set up respectively to process qualified batteries and unqualified batteries respectively.

[0040] The appearance inspection result of the battery is qualified or unqualified; the battery appearance inspection system also includes a qualified battery processing area and an unqualified battery processing area, and the logistics line includes a first logistics branch line and a second logistics branch line located after the sorting point. The first logistics branch line is used to transport the qualified batteries with the latest appearance inspection result at the sorting point to the qualified battery processing area, and the qualified battery processing area is used to provide them to qualified battery processing equipment for processing. The second logistics branch line is used to transport the unqualified batteries with the latest appearance inspection result at the sorting point to the unqualified battery processing area, and the unqualified battery processing area is used to provide them to visual inspection personnel for re-judgment or processing of the unqualified batteries.

[0041] Therefore, different material branches will be set up to flow qualified batteries and unqualified batteries separately.

[0042] Among them, the length of the logistics line segment between the visual inspection system and the sorting point is greater than the preset length.

[0043] Therefore, a longer logistics line segment can be set between the visual inspection system and the sorting point. The longer the logistics line segment between the visual inspection system and the sorting point, the longer the time required for the battery to be transported to the sorting point by the logistics line, which can provide more time for appearance re-judgment. Before the battery whose first inspection result meets the re-judgment conditions is transported to the sorting point, there is enough time to complete the appearance re-judgment of the battery, so as to use the second inspection result of the battery to update the latest appearance inspection result of the battery, so that the sorting system can accurately sort the battery based on the latest appearance inspection result of the battery - the second inspection result of the battery; in addition, since there is more time for appearance re-judgment, the accuracy of re-judgment can be improved and misjudgment can be reduced.

[0044] A second aspect of the present application provides a battery appearance inspection method, the method comprising: performing appearance inspection on batteries passing through a logistics line, and obtaining a first inspection result for each battery based on the marking information of each battery; in response to the first inspection result of the battery meeting the re-judgment condition, performing an appearance re-judgment on the battery based on the battery appearance information of the battery to obtain a second inspection result of the battery; and, in response to the logistics line transporting the battery to a sorting point, obtaining the latest appearance inspection result of the battery, wherein, in a case where the second inspection result of the battery does not currently exist, the latest appearance inspection result of the battery is the first inspection result, and in a case where the second inspection result of the battery currently exists, the latest appearance inspection result of the battery is the second inspection result, and the case where the second inspection result of the battery does not currently exist includes that the first inspection result of the battery meets the re-judgment condition and the second inspection result of the battery is not generated when the logistics line transports the battery to the sorting point; and sorting the battery based on the latest appearance inspection result of the battery.

[0045] During the transportation of batteries by the logistics line, the visual inspection system will perform an appearance inspection on the batteries and obtain the first inspection result of the batteries. After the batteries pass through the visual inspection system, the logistics line continues to transport the batteries to the sorting point. At the same time, the re-judgment cloud system is responsible for instructing the re-judgment edge system to re-judgment the appearance of the batteries if the first inspection result of the batteries meets the re-judgment conditions. Therefore, during the transportation of batteries by the logistics line, the appearance of the batteries whose first inspection results meet the re-judgment conditions is re-judged. The appearance re-judgment action and the transportation action of the batteries whose first inspection results meet the re-judgment conditions are carried out in parallel. That is, the transportation of batteries whose first inspection results meet the re-judgment conditions by the logistics line is continuous. The appearance re-judgment of batteries whose first inspection results meet the re-judgment conditions will not affect the rhythm of the logistics line's transportation. Therefore, the appearance re-judgment of batteries can be achieved without affecting the battery transportation rhythm, meeting the high-rhythm production requirements of the production line. That is, the accuracy of battery appearance inspection can be improved to a certain extent without affecting the battery transportation rhythm, reducing the occurrence of misjudgment of battery appearance inspection.

[0046] Among them, after obtaining the first detection result of each battery according to the marking information of each battery, the battery appearance detection method further includes: recording the marking information of the battery, and setting a target appearance state mark for the marking information of the battery when the first detection result of the battery is that the battery is in a target appearance state; after re-judging the appearance of the battery based on the battery appearance information of the battery and obtaining a second detection result of the battery, the battery appearance detection method further includes: in response to the second detection result of the battery being that the battery is not in the target appearance state, removing the target appearance state mark of the marking information of the battery; obtaining the latest appearance detection result of the battery, including: using the marking information of the battery at the sorting point as the mark to be queried, and querying whether the target appearance state mark is currently set for the mark to be queried, so as to determine the latest appearance detection result of the battery corresponding to the mark to be queried.

[0047] Therefore, the latest appearance inspection results of the battery can be recorded, updated and fed back through the production execution system.

[0048] In this technical solution, during the transportation of batteries along the logistics line, the batteries first pass through a visual inspection system located upstream of the logistics line. This visual inspection system then performs a visual inspection of the batteries and obtains a first inspection result. After passing through the visual inspection system upstream of the logistics line, the logistics line continues to transport the batteries to a sorting point located downstream of the logistics line. Simultaneously, the re-evaluation cloud system is responsible for instructing the re-evaluation edge system to conduct a visual re-evaluation of the batteries if the first inspection result meets the re-evaluation conditions. Therefore, during the process of transporting batteries on the logistics line, the appearance of the batteries whose first test results meet the re-judgment conditions is re-judged, and the appearance re-judgment and transportation actions of the batteries whose first test results meet the re-judgment conditions are carried out in parallel, that is, the logistics line continuously transports the batteries whose first test results meet the re-judgment conditions, and the appearance re-judgment of the batteries whose first test results meet the re-judgment conditions will not affect the rhythm of their transportation by the logistics line; therefore, the appearance re-judgment of the batteries can be achieved without affecting the battery transportation rhythm, meeting the high-rhythm production requirements of the production line, that is, the accuracy of battery appearance inspection can be improved to a certain extent without affecting the battery transportation rhythm, and the occurrence of misjudgment of battery appearance inspection can be reduced.

If the specific posture changes, the directional indication will also change accordingly.

[0053] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0054] In order to better understand the present application, the battery appearance inspection system and battery appearance inspection method provided by the present application are described in more detail below with reference to the accompanying drawings and specific embodiments.

[0055] Please see Figure 1 , Figure 1 1 is a schematic diagram of an embodiment of a battery appearance inspection system provided by the present application. The present application provides a battery appearance inspection system 100, which includes a sorting system 10, a visual inspection system 20, a re-judgment cloud system 30, and a re-judgment edge system 50.

[0056] The visual inspection system 20 is used to perform appearance inspection on batteries passing through the logistics line 11, and obtain a first inspection result for each battery based on the marking information of each battery, wherein the visual inspection system 20 is arranged upstream of the logistics line 11. The visual inspection system 20 can determine whether there are defects in the appearance of the battery by performing appearance inspection on the battery passing through the logistics line 11. In addition, since the visual inspection system 20 performs appearance inspection on the battery passing through the logistics line 11, the visual inspection system 20 performs appearance inspection on the battery during the transportation of the battery by the logistics line 11. Therefore, the transportation action and the appearance inspection action of the battery are performed in parallel, that is, the transportation of the battery by the logistics line 11 is continuous, and the appearance inspection of the battery passing through the logistics line 11 by the visual inspection system 20 will not affect the rhythm of the transportation of the battery by the logistics line 11; therefore, the appearance inspection of the battery can be achieved without affecting the rhythm of the battery transportation, meeting the high-rhythm production requirements of the production line, that is, it can determine whether there are defects in the appearance of the battery without affecting the rhythm of the battery transportation.

[0057] In response to the first inspection result of the battery meeting the re-inspection conditions, the re-inspection cloud system 30 instructs the re-inspection edge system 50 to re-inspect the battery's appearance based on the battery appearance information provided by the visual inspection system 20, thereby obtaining a second inspection result of the battery. Since the visual inspection system 20 has limited appearance inspection capabilities, it may misjudge the appearance of the battery. Therefore, if the first inspection result of the battery meets the re-inspection conditions, the appearance of the battery whose first inspection result meets the re-inspection conditions is re-inspected based on the battery appearance information provided by the visual inspection system 20, so as to further review the appearance of the battery whose first inspection result meets the re-inspection conditions. This improves the accuracy of the battery appearance inspection to a certain extent and reduces the occurrence of misjudgments in the battery appearance inspection. In addition, the re-evaluation cloud system 30 is responsible for instructing the re-evaluation edge system 50 to re-evaluate the battery's appearance when the first inspection result of the battery meets the re-evaluation conditions, that is, it is responsible for issuing the battery re-evaluation task to the re-evaluation edge system 50, and the re-evaluation edge system 50 is responsible for the specific execution of the battery appearance re-evaluation. The re-evaluation cloud system 30 and the re-evaluation edge system 50 cooperate with each other and have a clear division of labor to achieve accurate and efficient re-evaluation of the battery's appearance.

[0058] The sorting system 10 is used to respond to the logistics line 11 transporting the battery to the sorting point 12, and obtain the latest appearance inspection result of the battery, wherein the sorting point 12 is located downstream of the logistics line 11. When the second inspection result of the battery does not currently exist, the latest appearance inspection result of the battery is the first inspection result. When the second inspection result of the battery currently exists, the latest appearance inspection result of the battery is the second inspection result, and the battery is sorted based on the latest appearance inspection result of the battery. The situation where the second inspection result of the battery does not currently exist includes that the first inspection result of the battery meets the re-judgment condition and the second inspection result of the battery is not generated when the logistics line 11 transports the battery to the sorting point 12.

[0059] In one embodiment, the case where the second test result for the battery does not currently exist also includes the case where the first test result for the battery does not meet the re-testing condition. Since the first test result for the battery does not meet the re-testing condition, there is no need to re-test the appearance of the battery, and thus there is no second test result obtained by re-testing the appearance of the battery.

[0060] During the transportation of batteries along logistics line 11, they first pass through visual inspection system 20, located upstream of logistics line 11. Visual inspection system 20 performs a visual inspection on the batteries, generating a first inspection result. After passing visual inspection system 20, logistics line 11 continues to transport the batteries to sorting point 12. Meanwhile, re-evaluation cloud system 30 instructs re-evaluation edge system 50 to conduct a visual re-evaluation of the batteries if the first inspection result meets the re-evaluation criteria. Therefore, during the process of transporting batteries on the logistics line 11, the appearance of the batteries whose first test results meet the re-judgment conditions is re-judged. Therefore, the appearance re-judgment and transportation actions of the batteries whose first test results meet the re-judgment conditions are carried out in parallel, that is, the transportation of the batteries whose first test results meet the re-judgment conditions by the logistics line 11 is continuous, and the appearance re-judgment of the batteries whose first test results meet the re-judgment conditions will not affect the rhythm of their transportation by the logistics line 11; therefore, the appearance re-judgment of the batteries can be achieved without affecting the battery transportation rhythm, meeting the high-rhythm production requirements of the production line, that is, the accuracy of the battery appearance inspection can be improved to a certain extent without affecting the battery transportation rhythm, and the occurrence of misjudgment of the battery appearance inspection can be reduced.

[0061] Because the visual inspection system 20 performs a visual inspection of the batteries and obtains the first inspection result while the sorting system 10 controls the logistics line 11 for transporting the batteries, and because the re-evaluation cloud system 30 determines that the first inspection result meets the re-evaluation conditions while the sorting system 10 controls the logistics line 11 for transporting the batteries, it instructs the re-evaluation edge system 50 to perform a re-evaluation of the battery's appearance based on the battery appearance information provided by the visual inspection system 20. Therefore, the sorting system 10, the visual inspection system 20, the re-evaluation cloud system 30, and the re-evaluation edge system 50 operate in parallel.

[0062] The visual inspection system 20 can determine whether there are any defects in the appearance of the batteries by performing appearance inspections on the batteries passing through the logistics line 11. In addition, because the visual inspection system 20 and the sorting system 10 operate in parallel, the visual inspection system 20's appearance inspection of the batteries passing through the logistics line 11 will not affect the sorting system 10's control of the logistics line 11 to transport the batteries to the sorting point 12, nor will it affect the sorting system 10's response to the logistics line 11 transporting the batteries to the sorting point 12 and sorting the batteries based on the latest appearance inspection results. In other words, the appearance inspection of the batteries can be achieved without affecting the transportation and sorting rhythm of the batteries, meeting the high-beat production requirements of the production line.

[0063] When the re-judgment cloud system 30 determines that the first inspection result of the battery meets the re-judgment conditions, it instructs the re-judgment edge system 50 to re-judgment the appearance of the battery based on the battery appearance information provided by the visual inspection system 20, so as to further review the appearance of the battery whose first inspection result meets the re-judgment conditions, thereby improving the accuracy of the battery appearance inspection to a certain extent and reducing the occurrence of misjudgment of the battery appearance inspection. In addition, since the re-judgment cloud system 30, the re-judgment edge system 50 and the sorting system 10 work in parallel, when the re-judgment cloud system 30 determines that the first inspection result of the battery meets the re-judgment conditions, it instructs the re-judgment edge system 50 to re-judgment the appearance of the battery, and the re-judgment edge system 50 re-judgments the appearance of the battery. This will not affect the rhythm of the sorting system 10 controlling the logistics line 11 to transport the battery to the sorting point 12 and the sorting system 10 responding to the logistics line 11 to transport the battery to the sorting point 12 and sorting the battery based on the latest appearance inspection result of the battery; therefore, the appearance of the battery can be re-judged without affecting the rhythm of battery transportation and sorting, meeting the high-rhythm production requirements of the production line, that is, the accuracy of the battery appearance inspection can be improved to a certain extent without affecting the rhythm of battery transportation and sorting, and the occurrence of misjudgment of the battery appearance inspection can be reduced.

[0064] If a battery's first inspection result meets the re-judgment conditions, the re-judgment cloud system 30 will, upon determining that the battery's first inspection result meets the re-judgment conditions, instruct the re-judgment edge system 50 to conduct an appearance re-judgment of the battery based on the battery appearance information provided by the visual inspection system 20. At the same time, the sorting system 10 will control the logistics line 11 to continue transporting the battery to the sorting point 12. If, when the sorting system 10 controls the logistics line 11 to transport the battery to the sorting point 12, a second inspection result for the battery currently exists, the battery's latest appearance inspection result will be the battery's second inspection result. Then, when the sorting system 10 controls the logistics line 11 to transport the battery to the sorting point 12, the battery's latest appearance inspection result—the battery's second inspection result—will be obtained, and the battery will be sorted based on the battery's latest appearance inspection result—the battery's second inspection result. If, when the sorting system 10 controls the logistics line 11 to transport the battery to the sorting point 12, the second inspection result of the battery does not currently exist and the second inspection result of the battery cannot be obtained, then the latest appearance inspection result of the battery is the first inspection result of the battery; in this case, when the sorting system 10 controls the logistics line 11 to transport the battery to the sorting point 12, the latest appearance inspection result of the battery - the first inspection result of the battery - will be obtained, and the battery will be sorted according to the latest appearance inspection result of the battery - the first inspection result of the battery, without waiting for the re-inspection edge system 50 to complete the re-inspection of the battery's appearance before sorting it.

[0065] That is, the sorting system 10 and the re-testing edge system 50 operate in parallel. When a battery whose first test result meets the re-testing conditions is transported to the sorting point 12, the sorting system 10 will sort the battery regardless of whether a second test result of the battery currently exists. If a second test result of the battery does not currently exist, the sorting system 10 will not wait until a second test result of the battery exists before sorting the battery.

[0066] If a battery's first inspection result fails to meet the re-inspection criteria, the battery does not undergo appearance re-inspection. The sorting system 10 controls the logistics line 11 to continue transporting the battery to the sorting point 12. When the sorting system 10 controls the logistics line 11 to transport the battery to the sorting point 12, it obtains the battery's latest appearance inspection result—the battery's first inspection result—and sorts the battery based on this latest appearance inspection result.

[0067] For example, if Figure 1 As shown, the sorting system 10 controls the logistics line 11 to transport battery A. During the process of the sorting system 10 controlling the logistics line 11 to transport battery A, the visual inspection system 20 will first perform an appearance inspection on the battery A passing through the logistics line 11 to determine whether there are any defects in the appearance of battery A. Since the visual inspection system 20 and the sorting system 10 work in parallel, the appearance inspection of battery A passing through the logistics line 11 by the visual inspection system 20 will not affect the rhythm of the sorting system 10 controlling the logistics line 11 to transport battery A to the sorting point 12 and the sorting system 10 responding to the logistics line 11 to transport battery A to the sorting point 12 and sorting battery A based on the latest appearance inspection result of battery A. Therefore, the appearance inspection of battery A can be achieved without affecting the rhythm of transporting and sorting battery A, thereby meeting the high-rhythm production requirements of the production line.

[0068] After battery A undergoes appearance inspection by the visual inspection system 20, if the first inspection result of battery A meets the re-judgment conditions, then the re-judgment cloud system 30 will, upon determining that the first inspection result of the battery meets the re-judgment conditions, instruct the re-judgment edge system 50 to conduct an appearance re-judgment of battery A based on the battery appearance information provided by the visual inspection system 20; at the same time, the sorting system 10 controls the logistics line 11 to continue transporting battery A to the sorting point 12. If, when the sorting system 10 controls the logistics line 11 to transport battery A to the sorting point 12, a second inspection result of battery A currently exists, then the latest appearance inspection result of battery A is the second inspection result of battery A; then, when the sorting system 10 controls the logistics line 11 to transport battery A to the sorting point 12, the latest appearance inspection result of battery A—the second inspection result of the battery—will be obtained, and battery A will be sorted based on the latest appearance inspection result of battery A—the second inspection result of the battery. If, when the sorting system 10 controls the logistics line 11 to transport battery A to the sorting point 12, the second inspection result of battery A does not currently exist, the second inspection result of battery A cannot be obtained. At this time, the latest appearance inspection result of battery A is the first inspection result of battery A. In this case, when the sorting system 10 controls the logistics line 11 to transport battery A to the sorting point 12, the latest appearance inspection result of battery A - the first inspection result of battery A - will be obtained, and battery A will be sorted based on the latest appearance inspection result of battery A - the first inspection result of battery A, without waiting until the second inspection result of battery A exists before sorting it.

[0069] That is to say, if the first test result of battery A meets the re-judgment conditions, when battery A is transported to the sorting point 12 by the logistics line 11, the sorting system 10 will sort battery A regardless of whether there is a second test result for battery A. The sorting system 10 and the re-judgment edge system 50 work in parallel. The re-judgment of the appearance of battery A by the re-judgment edge system 50 will not affect the rhythm of the sorting system 10 controlling the logistics line 11 to transport battery A to the sorting point 12 and the sorting of the battery based on the latest appearance test result of battery A in response to the logistics line 11. Therefore, the appearance re-judgment of battery A can be achieved without affecting the transportation and sorting rhythm of battery A, meeting the high-beat production requirements of the production line.

[0070] In one embodiment, the length of the logistics line 11 between the visual inspection system 20 and the sorting point 12 is greater than a preset length. In other words, a longer logistics line segment can be provided between the visual inspection system 20 and the sorting point 12. A longer logistics line segment between the visual inspection system 20 and the sorting point 12 increases the time required for batteries to be transported from the logistics line 11 to the sorting point 12, providing more time for appearance re-inspection. Batteries whose first inspection results meet the re-inspection criteria have sufficient time to complete appearance re-inspection before being transported to the sorting point 12. This allows the battery's second inspection result to be used to update the battery's latest appearance inspection result, thereby enabling the sorting system 10 to accurately sort the battery based on the battery's latest appearance inspection result—the second inspection result. Furthermore, since more time is available for appearance re-inspection, re-inspection accuracy is improved and misjudgments are reduced.

[0071] There is no limitation on the size of the preset length, and it can be set according to actual needs.

[0072] In one embodiment, the first inspection result of the battery is either qualified or unqualified, and the re-judgment condition is that the first inspection result is that the battery is in the target appearance state, and the target appearance state is unqualified. Due to the limited appearance inspection capability of the visual inspection system 20, some qualified batteries may be mistakenly judged as unqualified batteries, resulting in over-killing. The re-judgment condition is that the first inspection result is that the battery is in an unqualified state, so the batteries that meet the re-judgment condition are unqualified batteries whose first inspection result is unqualified. By re-judging the appearance of unqualified batteries whose first inspection result is unqualified, the accuracy of battery appearance inspection is improved to a certain extent, and the over-kill rate is reduced.

[0073] In other embodiments, the first test result of the battery is either qualified or unqualified, and the re-judgment condition is that the first test result is that the battery is in the target appearance state, and the target appearance state is a qualified state. Due to the limited appearance inspection capability of the visual inspection system 20, some unqualified batteries may be mistakenly judged as qualified batteries, resulting in missed kills. The re-judgment condition is that the first test result is that the battery is in a qualified state, so the battery that meets the re-judgment condition is a qualified battery with a qualified first test result. By re-judging the appearance of qualified batteries with a qualified first test result, the accuracy of the battery appearance inspection is improved to a certain extent, and the missed kill rate is reduced.

[0074] In one embodiment, the battery appearance inspection system 100 further includes a production execution system 40, which is communicatively connected to the visual inspection system 20, the re-judgment cloud system 30, and the sorting system 10. The production execution system 40 is used to record the latest appearance inspection results of the battery based on the inspection results sent by the visual inspection system 20 or the re-judgment cloud system 30, and to feed back the latest appearance inspection results of the battery to the sorting system 10.

[0075] That is, the production execution system 40 will communicate and interact with the visual inspection system 20. After the visual inspection system 20 performs an appearance inspection on the battery passing through the logistics line 11 and obtains the first inspection result of the battery, it will send the inspection result to the production execution system 40. After receiving the inspection result sent by the visual inspection system 20, the production execution system 40 obtains the latest appearance inspection result of the battery based on it. In addition, the production execution system 40 will also communicate and interact with the re-judgment cloud system 30. After the re-judgment edge system 50 performs an appearance re-judgment on the battery, it will send the second inspection result of the battery to the re-judgment cloud system 30. The re-judgment cloud system 30 will send the inspection result to the production execution system 40. After receiving the inspection result sent by the re-judgment cloud system 30, the production execution system 40 obtains the latest appearance inspection result of the battery based on it. In addition, the production execution system 40 will also communicate and interact with the sorting system 10. Before the sorting system 10 sorts the battery, it will determine the latest appearance inspection result of the battery through the production execution system 40 and sort the battery based on it.

[0076] That is, the latest appearance inspection results of the battery are recorded and fed back through the production execution system 40 .

[0077] It should be noted that if the first inspection result of a battery meets the re-judgment conditions, but the second inspection result of the battery is not generated when the battery is transported to the sorting point 12 on the logistics line 11, it includes the following situations: The first situation is that the re-judgment edge system 50 has not completed the re-judgment of the appearance of the battery. Since the re-judgment edge system 50 has not completed the re-judgment of the appearance of the battery, the re-judgment cloud system 30 cannot obtain the second inspection result of the battery, and the production execution system 40 cannot obtain the second inspection result of the battery; therefore, when the re-judgment edge system 50 has not completed the re-judgment of the appearance of the battery, the second inspection result of the battery is not generated, resulting in the current non-existence of the second inspection result of the battery. The latest appearance inspection result of the battery is the first inspection result of the battery, and the latest appearance inspection result of the battery recorded by the production execution system 40 is the first inspection result of the battery. The second situation is that the re-evaluation edge system 50 completes the re-evaluation of the appearance of the battery, but the re-evaluation edge system 50 has not yet sent the second inspection result of the battery to the re-evaluation cloud system 30, so the re-evaluation cloud system 30 cannot obtain the second inspection result of the battery, and the production execution system 40 cannot obtain the second inspection result of the battery; therefore, when the re-evaluation edge system 50 completes the re-evaluation of the appearance of the battery, but the re-evaluation edge system 50 has not yet sent the second inspection result of the battery to the re-evaluation cloud system 30, the second inspection result of the battery is not generated, resulting in the current non-existence of the second inspection result of the battery. The latest appearance inspection result of the battery is the first inspection result of the battery, and the latest appearance inspection result of the battery recorded by the production execution system 40 is the first inspection result of the battery. The third situation is that the re-evaluation edge system 50 completes the re-evaluation of the appearance of the battery and the re-evaluation edge system 50 sends the second inspection result of the battery to the re-evaluation cloud system 30, but the re-evaluation cloud system 30 has not yet sent the second inspection result of the battery to the production execution system 40, and the latest appearance inspection result of the battery recorded by the production execution system 40 is the first inspection result of the battery; therefore, when the re-evaluation edge system 50 completes the re-evaluation of the appearance of the battery and the re-evaluation edge system 50 sends the second inspection result of the battery to the re-evaluation cloud system 30, but the re-evaluation cloud system 30 has not yet sent the second inspection result of the battery to the production execution system 40, the second inspection result of the battery is not generated, resulting in the current non-existence of the second inspection result of the battery, and the latest appearance inspection result of the battery is the first inspection result of the battery.

[0078] It should be noted that the production execution system described in this article consists of a comprehensive dynamic software system developed by IT.

[0079] In a specific embodiment, the production execution system 40 is used to receive the first detection information sent by the visual inspection system 20, the first detection information includes the marking information of the battery and the first detection result of the battery, and save the first detection result as the latest appearance inspection result of the battery corresponding to the marking information.

[0080] Specifically, the production execution system 40 will communicate and interact with the visual inspection system 20. After the visual inspection system 20 performs an appearance inspection on the battery passing through the logistics line 11 and obtains a first inspection result of the battery, it will send first inspection information including the marking information of the battery and the first inspection result of the battery to the production execution system 40; after the production execution system 40 receives the first inspection information including the marking information of the battery and the first inspection result of the battery sent by the visual inspection system 20, it saves the first inspection result of the battery and the marking information of the battery, and uses the first inspection result as the latest appearance inspection result of the battery corresponding to the marking information.

[0081] The battery marking information serves as the battery's unique "digital ID card". Through the battery marking information, the latest appearance inspection results of different batteries can be distinguished. On the one hand, the latest appearance inspection results of the battery can be accurately fed back to the sorting system 10 later; on the other hand, the appearance inspection results of the battery that needs to be updated can be accurately updated.

[0082] The production execution system 40 is used to receive the second detection information sent by the re-evaluation cloud system 30, the second detection information including the battery marking information and the second detection result of the battery, and use the second detection information to update the latest appearance detection result of the battery.

[0083] Specifically, the re-judgment edge system 50 performs an appearance re-judgment on the battery whose first inspection result meets the re-judgment conditions, and after obtaining the second inspection result of the battery, the second inspection result of the battery will be fed back to the re-judgment cloud system 30; the production execution system 40 will communicate and interact with the re-judgment cloud system 30, and the re-judgment cloud system 30 will send the second inspection information including the battery marking information and the second inspection result of the battery to the production execution system 40; after the production execution system 40 receives the second inspection information including the battery marking information and the second inspection result of the battery sent by the re-judgment cloud system 30, it uses it to update the latest appearance inspection result of the battery.

[0084] The production execution system 40 is used to receive the mark information sent by the sorting system 10 as the mark to be queried, and feed back the latest appearance inspection result of the battery corresponding to the mark to be queried to the sorting system 10.

[0085] Specifically, the production execution system 40 will communicate and interact with the sorting system 10. Before the sorting system 10 sorts the batteries, it will send a mark to be queried to the production execution system 40, where the mark to be queried is the marking information of the battery. The production execution system 40 can query the latest appearance inspection results of the battery based on the marking information of the battery, and feedback to the sorting system 10, so that the sorting system 10 can accurately sort the batteries based on the latest appearance inspection results of the battery.

[0086] That is, the latest appearance inspection results of the battery are recorded, updated, and fed back through the production execution system 40 .

[0087] The marking information of the battery may be the ID code of the battery.

[0088] In a specific embodiment, the re-judgment cloud system 30 is further used to send second detection information when it is determined that a preset condition is currently met, wherein the preset condition includes at least one of the following: the sorting system 10 is not currently sorting the battery, and the second detection result of the battery is inconsistent with the first detection result of the battery.

[0089] The preset conditions include that the second inspection result of the battery is inconsistent with the first inspection result of the battery; that is, when the second inspection result of the battery is inconsistent with the first inspection result of the battery, the re-judgment cloud system 30 sends a second inspection information to the production execution system 40, so that the production execution system 40 uses the second inspection information to update the latest appearance inspection result of the battery. The second inspection result of the battery is inconsistent with the first inspection result of the battery, which means that the first inspection result detected by the visual inspection system 20 for the battery is incorrect. Then, the latest appearance inspection result of the battery currently saved by the production execution system 30 - the first inspection result of the battery - is incorrect, and the latest appearance inspection result of the battery currently saved by the production execution system 40 - the first inspection result of the battery cannot truly reflect the appearance of the battery. At this time, the latest appearance inspection result of the battery saved by the production execution system 40 will be updated, and the latest appearance inspection result of the battery will be updated to the second inspection result of the battery, so that the latest appearance inspection result of the battery saved by the production execution system 40 can accurately reflect the appearance of the battery. If the latest appearance inspection results of the batteries stored in the production execution system 40 are updated before the logistics line 11 transports the batteries to the sorting point 12, then when the sorting system 10 sorts the batteries, the production execution system 40 can provide feedback to the sorting system 10 on the latest appearance inspection results reflecting the actual appearance of the batteries, allowing the sorting system 10 to accurately sort the batteries based on the latest appearance inspection results. If the latest appearance inspection results of the batteries stored in the production execution system 40 are updated after the logistics line 11 transports the batteries to the sorting point 12, the updated appearance inspection results facilitate subsequent inquiries by users to determine the actual appearance of the batteries, facilitating traceability.

[0090] The preset condition includes the fact that the sorting system 10 is not currently sorting batteries. That is, when the sorting system 10 is not currently sorting batteries, the second inspection information is sent to the production execution system 40 so that the production execution system 40 can use the second inspection information to update the latest appearance inspection results of the batteries. Because the sorting system 10 sorts batteries based on the latest appearance inspection results of the batteries stored by the production execution system 40, whether the latest appearance inspection results currently stored by the production execution system 40 are updated or not affects the sorting of batteries by the sorting system 10. If the sorting system 10 is currently sorting batteries, then whether the latest appearance inspection results currently stored by the production execution system 40 are updated or not no longer affects the sorting of batteries by the sorting system 10, and there is no need to update the latest appearance inspection results currently stored by the production execution system 40. If the sorting system 10 is not currently sorting the batteries, then whether the latest appearance inspection results of the batteries currently saved in the production execution system 40 are updated or not will affect the sorting of the batteries by the sorting system 10. In other words, the latest appearance inspection results of the batteries currently saved in the production execution system 40 need to be updated so that the subsequent sorting system 10 can accurately sort the batteries.

[0091] The preset conditions include that the sorting system 10 is not currently sorting the battery and the second test result of the battery is inconsistent with the first test result of the battery; that is, when the sorting system 10 is not currently sorting the battery and the second test result of the battery is inconsistent with the first test result of the battery, the second test information is sent to the production execution system 40 so that the production execution system 40 uses it to update the latest appearance test result of the battery. The second inspection result of the battery is inconsistent with the first inspection result of the battery, which means that the first inspection result of the battery is incorrect. Therefore, the latest appearance inspection result of the battery currently saved by the production execution system 40 - the first inspection result of the battery is incorrect. The latest appearance inspection result of the battery currently saved by the production execution system 40 - the first inspection result of the battery cannot truly reflect the appearance of the battery. Since the sorting system 10 sorts the batteries based on the latest appearance inspection result of the battery saved by the production execution system 40, whether the latest appearance inspection result of the battery currently saved by the production execution system 40 is updated or not will affect the battery sorting by the sorting system 10. If the sorting system 10 is not currently sorting the batteries, whether the latest appearance inspection result of the battery currently saved by the production execution system 40 is updated or not will affect the battery sorting by the sorting system 10. At this time, the latest appearance inspection result of the battery saved in the production execution system 40 will be updated, and the latest appearance inspection result of the battery will be updated to the second inspection result of the battery, so that the latest appearance inspection result of the battery saved in the production execution system 40 can accurately reflect the actual appearance of the battery. Then, when the sorting system 10 sorts the battery, the production execution system 40 can feed back the latest appearance inspection result reflecting the actual appearance of the battery to the sorting system 10, so that the sorting system 10 can accurately sort the battery based on the latest appearance inspection result of the battery.

[0092] Specifically, the re-judgment edge system 50 performs an appearance re-judgment on the battery whose first inspection result meets the re-judgment conditions, and after obtaining the second inspection result of the battery, the second inspection result of the battery will be fed back to the re-judgment cloud system 30; the production execution system 40 will communicate and interact with the re-judgment cloud system 30, and the re-judgment cloud system 30 determines whether the second inspection result of the battery is consistent with the first inspection result of the battery, and when it is determined that the second inspection result of the battery is inconsistent with the first inspection result of the battery, a query instruction including the marking information of the battery is sent to the production execution system 40 to determine whether the battery has been sorted by the sorting system 10; then, the production execution system 40 feeds back the query result to the re-judgment cloud system 30; then, the re-judgment cloud system 30 determines whether the battery has been sorted based on the query result fed back by the production execution system 40, and when it is determined that the battery has not been sorted by the sorting system 10, the second inspection information including the marking information of the battery and the second inspection result of the battery is sent to the production execution system 40; after the production execution system 40 receives the second inspection information including the marking information of the battery and the second inspection result of the battery sent by the re-judgment cloud system 30, it uses it to update the latest appearance inspection result of the battery.

[0093] In a specific embodiment, the re-judgment condition is: the first detection result is that the battery is in the target appearance state; the production execution system 40 executes and saves the first detection result as the latest appearance detection result of the battery corresponding to the marking information, including: recording the marking information of the battery, and setting the target appearance state mark for the marking information of the battery.

[0094] Specifically, the production execution system 40 will communicate and interact with the visual inspection system 20. After the visual inspection system 20 performs an appearance inspection on the battery passing through the logistics line 11 and obtains the first inspection result of the battery, it will send the first inspection information including the marking information of the battery and the first inspection result of the battery to the production execution system 40. After the production execution system 40 receives the first inspection information including the marking information of the battery and the first inspection result of the battery sent by the visual inspection system 20, it determines whether the battery is in the target appearance state based on the first inspection result of the battery. When it is determined that the battery is in the target appearance state, the marking information of the battery is recorded and the target appearance state mark is set for the marking information of the battery. In addition, when the production execution system 40 determines that the battery is not in the target appearance state based on the first inspection result of the battery, it only records the marking information of the battery.

[0095] For example, the first inspection result of battery A is that the battery is unqualified, and the re-judgment condition is that the first inspection result is that the battery is in the target appearance state, and the target appearance state is unqualified. After the visual inspection system 20 performs an appearance inspection on battery A passing through the logistics line 11 and obtains the first inspection result of battery A as unqualified, it will send first inspection information including the marking information of battery A and the first inspection result of battery A to the production execution system 40; after the production execution system 40 receives the first inspection information including the marking information of battery A and the first inspection result of battery A sent by the visual inspection system 20, it determines that battery A is unqualified based on the first inspection result of battery A, records the marking information of battery A, and sets the target appearance state mark for the marking information.

[0096] The production execution system 40 updates the latest appearance inspection result of the battery using the second inspection information, including: in response to the second inspection result of the battery being that the battery is not in the target appearance state, removing the target appearance state mark of the battery marking information.

[0097] Specifically, after the production execution system 40 receives the second detection information including the battery marking information and the second detection result of the battery sent by the re-judgment cloud system 30, it determines whether the re-judgmented battery is not in the target appearance state based on the second detection result of the battery, and when it is determined that the re-judgmented battery is not in the target appearance state, the target appearance state mark of the battery marking information is removed.

[0098] For example, the first test result for battery A is unqualified, and the re-judgment condition is that the first test result shows that the battery is in the target appearance state, and the target appearance state is unqualified. After receiving the second test information including the marking information of battery A and the second test result of battery A from the re-judgment cloud system 30, the production execution system 40 determines that battery A is not unqualified based on the second test result of battery A and removes the target appearance state flag from the marking information of battery A.

[0099] For another example, the first test result of battery A is that the battery is unqualified, and the re-evaluation condition is that the first test result is that the battery is in the target appearance state, and the target appearance state is unqualified. After the appearance of battery A is re-evaluated and the second test result of battery A is obtained as the battery is unqualified, the second test information including the marking information of battery A and the second test result of battery A will not be sent to the production execution system 40, and the production execution system 40 will not remove the target appearance state mark of the marking information of battery A. Alternatively, after the appearance of battery A is re-evaluated and the second test result of battery A is obtained as the battery is unqualified, the second test information including the marking information of battery A and the second test result of battery A will be sent to the production execution system 40; after the production execution system 40 receives the second test information including the marking information of battery A and the second test result of battery A sent by the re-evaluation cloud system 30, based on the second test result of battery A, it is determined that the re-evaluated battery A is still in the unqualified state, and the target appearance state mark of the marking information of battery A will not be removed.

[0100] The sorting system 10 is further configured to query the production execution system 40 whether the target appearance status flag is currently set for the mark to be queried, so as to determine the latest appearance inspection result of the battery corresponding to the mark to be queried.

[0101] Specifically, the production execution system 40 communicates and interacts with the sorting system 10. Before the sorting system 10 sorts the batteries, it sends a mark to be queried to the production execution system 40, where the mark to be queried is the marking information of the battery. The production execution system 40 can query whether the marking information of the battery is set with the target appearance status mark based on the marking information of the battery, and feedback to the sorting system 10. The sorting system 10 sorts the batteries based on whether the marking information of the battery is set with the target appearance status mark.

[0102] For example, the first test result of battery A is that the battery is unqualified, and the re-judgment condition is that the first test result is that the battery is in the target appearance state, and the target appearance state is unqualified. After the appearance of battery A is re-judged and the second test result of battery A is obtained, the second test information including the marking information of battery A and the second test result of battery A is sent to the production execution system 40; after the production execution system 40 receives the second test information including the marking information of battery A and the second test result of battery A sent by the re-judgment cloud system 30, the target appearance state mark of the marking information of battery A is removed based on the second test result of battery A. When the sorting system 10 needs to sort battery A, it will send a pending query mark to the production execution system 40, and the pending query mark is the marking information of battery A; based on the received pending query mark, the production execution system 40 finds that the marking information of battery A is not set with the target appearance state mark and feedback is given to the sorting system 10, and the sorting system 10 sorts battery A based on the result fed back by the production execution system 40.

[0103] For another example, the first test result of battery A is that the battery is unqualified, and the re-judgment condition is that the first test result is that the battery is in the target appearance state, and the target appearance state is an unqualified state. After the appearance of battery A is re-judged and the second test result of battery A is obtained as the battery is unqualified, the second test information including the marking information of battery A and the second test result of battery A will not be sent to the production execution system 40, and the production execution system 40 will not remove the target appearance state mark of the marking information of battery A. When the sorting system 10 needs to sort battery A, it will send a pending query mark to the production execution system 40, and the pending query mark is the marking information of battery A; based on the received pending query mark, the production execution system 40 finds that the marking information of battery A is set with the target appearance state mark and feeds back to the sorting system 10, and the sorting system 10 sorts battery A based on the result fed back by the production execution system 40.

[0104] Setting a target appearance state flag for the tag information assigns a classification identifier reflecting the battery's appearance to the battery corresponding to the tag information. This reduces memory consumption compared to recording the appearance test results corresponding to the tag information. Furthermore, if the battery is re-determined not to be in the target appearance state, the target appearance state flag for the tag information can simply be removed. Furthermore, when sorting batteries, the sorting system 10 can determine the latest appearance test results based on whether the battery's tag information currently has the target appearance state flag set. This allows for faster response times for the sorting system 10 and improves battery sorting efficiency.

[0105] In other specific embodiments, the re-judgment cloud system 30 may also send a mark release instruction including the battery's marking information to the production execution system 40 when the second test result of the battery is inconsistent with the first test result of the battery, so that the production execution system 40 removes the target appearance status mark of the marking information after receiving the mark release instruction.

[0106] In one embodiment, the production execution system 40 is further configured to record the battery's sorting status as sorted in response to the sorting system 10 sorting the batteries. Specifically, after the sorting system 10 sorts the batteries based on the latest appearance inspection results, it sends a battery sorting notification including the battery's tag information to the production execution system 40. Upon receiving the battery sorting notification, the production execution system 40 marks the tag information as sorted, thereby recording the battery's sorting status as sorted.

[0107] In a specific embodiment, the production execution system 40 is further used to detect that the batteries in the battery container are taken out, record the container identification of the battery container, and alert the sorting system 10, wherein the battery container is used to accommodate the batteries sorted by the sorting system 10.

[0108] In a specific embodiment, the visual inspection system 20 is corresponding to the inspection station (not shown in the figure) provided at the logistics line 11. The visual inspection system 20 includes a first battery identification device 21. The first battery identification device 21 is located at the feeding position of the inspection station (not shown in the figure) and is used to identify the marking information of the batteries transported by the logistics line 11. The visual inspection system 20 is also used to respond to the first battery identification device 21 identifying the marking information of the battery and send the marking information identified by the first battery identification device 21 to the production execution system 40. In other words, the first battery identification device 21 is provided at the feeding position of the inspection station of the logistics line 11. When the battery is transported by the logistics line 11 to the feeding position of the inspection station, the first battery identification device 21 will identify the marking of the battery to obtain the marking information of the battery; then, the visual inspection system 20 sends the marking information of the battery identified by the first battery identification device 21 to the production execution system 40; then, the production execution system 40 receives and records the marking information of the battery. Since the first battery identification device 21 is located at the feed position of the inspection station, and the appearance inspection of the battery begins after the battery is transported to the feed position of the inspection station by the logistics line 11, after the production execution system 40 receives the marking information of the battery identified by the first battery identification device 21, it will also mark the marking information with a third identifier indicating that it has entered the appearance inspection state, so that the user can understand the current state of the battery. In addition, the appearance inspection of the battery begins after the battery is transported to the feed position of the inspection station by the logistics line 11, that is, after the battery is transported to the feed position of the inspection station by the logistics line 11, the state of the battery changes (enters the appearance inspection state), and since the first battery identification device 21 is located at the feed position of the inspection station, the change in the state of the battery can be fed back to the production execution system 40 as soon as the battery state changes.

[0109] In a specific embodiment, the marking information of the battery is an ID code, and the first battery identification device 21 is an ID code identification device.

[0110] In a specific embodiment, the visual inspection system 20 corresponds to an inspection station provided on the logistics line 11. The visual inspection system 20 includes a second battery identification device 22. The second battery identification device 22 is located at the discharge position of the inspection station (not shown in the figure) and is used to identify the marking information of the batteries transported by the logistics line 11. The visual inspection system 20 is also used to respond to the second battery identification device 22 identifying the marking information of the battery, and send the marking information of the battery identified by the second battery identification device 22 and the first inspection result of the battery to the production execution system 40.

[0111] That is to say, a second battery identification device 22 is provided at the discharge position of the inspection station of the logistics line 11. When the battery is transported to the discharge position of the inspection station by the logistics line 11, the second battery identification device 22 will mark and identify the battery to obtain the marking information of the battery; then, the visual inspection system 20 sends the marking information of the battery identified by the second battery identification device 22 to the production execution system 40; then, the production execution system 40 receives and saves the first inspection result as the latest appearance inspection result of the battery corresponding to the marking information.

[0112] The battery marking information serves as the battery's unique "digital ID card." Through the battery marking information, the latest appearance inspection results of different batteries can be distinguished. On the one hand, the latest appearance inspection results of the battery can be quickly located and accurately fed back to the sorting system 10. On the other hand, the appearance inspection results of batteries that need to be updated can be accurately updated. In addition, since the second battery identification device 22 is located at the discharge position of the inspection station, and the battery appearance inspection is completed after the battery is transported to the discharge position of the inspection station by the logistics line 11, after the production execution system 40 receives the battery marking information identified by the second battery identification device 22, it will also mark the marking information with a fourth identifier indicating the completion of the appearance inspection status, so that the user can understand the current status of the battery. Furthermore, the appearance inspection of the battery is completed after the battery is transported to the discharge position of the inspection station by the logistics line 11, that is, the state of the battery changes (the appearance inspection state is completed) after the battery is transported to the discharge position of the inspection station by the logistics line 11. Since the second battery identification device 22 is located at the discharge position of the inspection station, the battery state change can be fed back to the production execution system 40 as soon as the battery state changes.

[0113] In a specific embodiment, the marking information of the battery is an ID code, and the second battery identification device 22 is an ID code identification device.

[0114] In one embodiment, the visual inspection system 20 includes an image acquisition device (not shown in the figure) and at least one battery recognition device, the battery recognition device is used to identify the marking information of the batteries transported on the logistics line 11, and the image acquisition device is used to collect battery images of the batteries transported on the logistics line 11; the visual inspection system 20 is specifically used to use the battery image to perform an appearance inspection on the battery to obtain a first inspection result of the battery, and associate the first inspection result of the battery with the corresponding marking information.

[0115] That is, during the process of transporting batteries on the logistics line 11, the image acquisition device of the visual inspection system 20 acquires battery images of the batteries, and the battery recognition device of the visual inspection system 20 recognizes the marking information of the batteries. Based on the battery images of the batteries acquired by the image acquisition device, the visual inspection system 20 performs an appearance inspection on the batteries and obtains a first inspection result of the batteries, so as to determine whether there are any defects in the appearance of the batteries. In addition, the visual inspection system 20 establishes an association between the first inspection result of the batteries and the marking information of the batteries, and can subsequently quickly locate the first inspection result of the batteries through the marking information of the batteries. Since the visual inspection system 20 completes battery image acquisition, battery marking recognition, battery appearance inspection, and association of the battery marking with the first inspection result during the process of transporting batteries on the logistics line 11, the series of appearance inspection actions on the batteries and the transportation actions of the batteries are performed in parallel. That is, the transportation of batteries on the logistics line 11 is continuous, and the series of appearance inspection actions on the batteries will not affect the rhythm of the transportation of batteries on the logistics line 11. Therefore, the appearance inspection of the batteries can be achieved without affecting the rhythm of the battery transportation, meeting the high-rhythm production requirements of the production line.

[0116] In one specific embodiment, the visual inspection system 20 is located at an inspection station on the logistics line 11. The at least one battery identification device includes a first battery identification device 21 and a second battery identification device 22. The first battery identification device 21 and the second battery identification device 22 are located at the infeed and outfeed positions of the inspection station, respectively. It should be noted that the visual inspection system 20 can select the marking information of the battery identified by one of the first battery identification device 21 and the second battery identification device 22 and associate it with the first inspection result of the battery.

[0117] Of course, in other specific implementations, the battery identification device may be provided only at the feeding position or the discharging position of the detection station, which is not limited here.

[0118] In one specific embodiment, the image acquisition device and at least one battery identification device are located before the sorting point 12. Therefore, the visual inspection system 20 performs appearance inspection of the batteries before the sorting system 10 sorts the batteries. This allows the sorting system 10 to separate batteries with and without appearance defects, ensuring battery consistency.

[0119] In one embodiment, the visual inspection system 20 is specifically configured to perform defect detection on a battery using a battery image, obtain a defect detection result, and obtain a first inspection result of the battery based on the defect detection result. The first inspection result indicates whether the battery is qualified. In other words, the battery is determined to be qualified based on the defect detection result of the battery image.

[0120] In a specific embodiment, the first inspection result of the battery indicates that the battery is qualified or unqualified. When the defect inspection result of the battery indicates that there are candidate defects on the surface of the battery, the first inspection result of the battery is that the battery is unqualified. When the defect inspection result of the battery indicates that there are no candidate defects on the surface of the battery, the first inspection result of the battery is that the battery is qualified.

[0121] In one specific embodiment, the battery image includes sub-images of each surface to be inspected, the defect detection result includes a sub-detection result corresponding to each surface to be inspected, and the first detection result of the battery is either a qualified battery or a failed battery. When the sub-detection result of any surface to be inspected indicates the presence of a candidate defect on the surface to be inspected, the first detection result of the battery is a failed battery. When the sub-detection results of all surfaces to be inspected indicate the absence of a candidate defect on the surface to be inspected, the first detection result of the battery is a qualified battery.

[0122] In one embodiment, the visual inspection system 20 is further configured to send a re-inspection request message regarding the battery to the re-inspection cloud system 30 when the first inspection result of the battery meets the re-inspection conditions, wherein the re-inspection request message includes the battery's marking information, the battery's appearance information, and the first inspection result, and the battery's appearance information includes at least one of a battery image and location information of a candidate defective area of ​​the battery. The re-inspection cloud system 30 is configured to receive the re-inspection request message regarding the battery sent by the visual inspection system 20, generate a re-inspection task for the battery, and assign the re-inspection task to the re-inspection edge system 50. The re-inspection edge system 50 receives a second inspection result of the battery fed back after executing the re-inspection task, and updates the second inspection result of the battery as the latest appearance inspection result of the battery.

[0123] That is to say, when the first detection result of the battery detected by the visual inspection system 20 meets the re-judgment conditions, the visual inspection system 20 sends a re-judgment request information about the battery to the re-judgment cloud system 30, so that after receiving the re-judgment request information about the battery sent by the visual inspection system 20, the re-judgment cloud system 30 assigns a re-judgment task to the re-judgment edge system 50, so that the re-judgment edge system 50 performs a re-judgment of the appearance of the battery.

[0124] It should be noted that the first test result of a battery is either qualified or unqualified. The re-test condition is that the first test result shows that the battery is in the target appearance state, and the target appearance state is qualified. Therefore, batteries that meet the re-test condition are batteries with a qualified first test result. When performing an appearance re-test on a qualified battery with a qualified first test result, the re-test request information does not include the location information of the candidate defect areas of the battery.

[0125] The battery image may include sub-images of each surface to be inspected of the battery. When the re-inspection request information about the battery including the battery image is sent to the re-inspection cloud system 30 , sub-images of all surfaces to be inspected of the battery may be sent to the re-inspection cloud system 30 .

[0126] In addition, it should be noted that the first test result of the battery is either qualified or unqualified, and the re-judgment condition is that the first test result is that the battery is in the target appearance state, and the target appearance state is unqualified. Therefore, the battery that meets the re-judgment condition is the battery with an unqualified first test result. When performing an appearance re-judgment on an unqualified battery with an unqualified first test result, and the re-judgment request information includes a battery image, and the battery image includes sub-images of each surface to be inspected of the battery, the sub-images of the surface to be inspected where the candidate defect is present can be sent to the re-judgment cloud system 30.

[0127] In one embodiment, the re-judgment cloud system 30 is further configured to, upon determining that a preset condition is currently satisfied, execute a step of updating the second inspection result of the battery as the latest appearance inspection result of the battery, wherein the preset condition includes at least one of the following: the sorting system 10 is not currently sorting the battery, and the second inspection result of the battery is inconsistent with the first inspection result of the battery.

[0128] The preset conditions include that the second test result of the battery is inconsistent with the first test result of the battery; that is, when the second test result of the battery is inconsistent with the first test result of the battery, the second test result of the battery is updated as the latest appearance test result of the battery. The inconsistency between the second test result of the battery and the first test result of the battery indicates that the first test result of the battery is incorrect, so the latest appearance test result of the battery - the first test result of the battery is incorrect, and the latest appearance test result of the battery - the first test result of the battery cannot truly reflect the appearance of the battery. At this time, the second test result of the battery is updated as the latest appearance test result of the battery, and the latest appearance test result of the battery is updated to the second test result of the battery, so that the latest appearance test result of the battery can accurately reflect the appearance of the battery. If the second test result of the battery is updated as the latest appearance test result of the battery before the logistics line 11 transports the battery to the sorting point 12, then when the sorting system 10 sorts the battery, it can accurately sort the battery based on the latest appearance test result of the battery that reflects the true appearance of the battery. If the second inspection result of the battery is updated as the latest appearance inspection result of the battery, it is after the logistics line 11 transports the battery to the sorting point 12. Since the latest appearance inspection result of the battery is updated, it is convenient for users to make subsequent inquiries to determine the true appearance of the battery and facilitate traceability.

[0129] The preset condition includes that the sorting system 10 is not currently sorting the batteries, that is, when the sorting system 10 is not currently sorting the batteries, the second inspection result of the batteries is updated as the latest appearance inspection result of the batteries. Since the sorting system 10 sorts the batteries based on the latest appearance inspection result of the batteries, whether the latest appearance inspection result of the batteries is updated or not affects the battery sorting by the sorting system 10. If the sorting system 10 is currently sorting the batteries, then whether the latest appearance inspection result of the batteries is updated or not will no longer affect the battery sorting by the sorting system 10, and there is no need to update the latest appearance inspection result of the batteries. If the sorting system 10 is not currently sorting the batteries, then whether the latest appearance inspection result of the batteries is updated or not will still affect the battery sorting by the sorting system 10, and it is necessary to update the latest appearance inspection result of the batteries.

[0130] The preset conditions include that the sorting system 10 is not currently sorting the battery and that the second inspection result of the battery is inconsistent with the first inspection result of the battery; that is, when the sorting system 10 is not currently sorting the battery and the second inspection result of the battery is inconsistent with the first inspection result of the battery, the second inspection result of the battery is updated as the latest appearance inspection result of the battery. The inconsistency between the second inspection result of the battery and the first inspection result of the battery indicates that the first inspection result of the battery is incorrect. Therefore, the latest appearance inspection result of the battery - the first inspection result of the battery is incorrect, and the latest appearance inspection result of the battery - the first inspection result of the battery cannot truly reflect the appearance of the battery. Since the sorting system 10 sorts the battery based on the latest appearance inspection result of the battery, whether the latest appearance inspection result of the battery is updated or not affects the sorting of the battery by the sorting system 10. If the sorting system 10 is not currently sorting the battery, whether the latest appearance inspection result of the battery is updated or not affects the sorting of the battery by the sorting system 10. At this time, the latest appearance inspection result of the battery will be updated so that the latest appearance inspection result of the battery can accurately reflect the appearance of the battery. Then, when the sorting system 10 sorts the batteries, it can accurately sort the batteries based on the latest appearance inspection result that reflects the actual appearance of the battery.

[0131] In a specific embodiment, the preset conditions include that the sorting system 10 is not currently sorting the batteries; the battery appearance inspection system 100 also includes a production execution system 40, which is used to record the sorting status of the batteries transported by the logistics line 11; the re-judgment cloud system 30 is also used to query the production execution system 40 about the current sorting status of the batteries to determine whether the sorting system 10 is currently sorting the batteries.

[0132] After the sorting system 10 sorts the batteries based on the latest appearance inspection results, it feeds back the battery sorting status to the production execution system 40, allowing the production execution system 40 to immediately learn and record the battery sorting status, thereby enabling a quick and accurate response to subsequent battery sorting status inquiries from the re-evaluation cloud system 30. Because the re-evaluation cloud system 30 updates the second inspection result of the battery as the latest appearance inspection result of the battery after determining that the sorting system 10 is not currently sorting the battery, the re-evaluation cloud system 30 also determines through the production execution system 40 whether the sorting system 10 is currently sorting the battery to determine whether the second inspection result of the battery needs to be used to update the latest appearance inspection result of the battery.

[0133] In one embodiment, the re-judgment cloud system 30 is composed of a server, image scheduling software, algorithms, etc.

[0134] In a specific embodiment, the re-judgment edge system 50 is composed of re-judgment software, an industrial computer, a display screen, etc.

[0135] In a specific embodiment, the re-inspection request information includes battery appearance information, and the battery appearance information includes a battery image of the battery and location information of the candidate defect area of ​​the battery in the battery image; the re-inspection cloud system 30 is also used to mark the candidate defect area of ​​the battery image based on the location information of the candidate defect area, and when assigning a re-inspection task to the re-inspection edge system 50, send the marked battery image to the re-inspection edge system 50.

[0136] By marking the candidate defect areas of the battery image, the candidate defect areas in the marked battery image are highlighted, so that when the re-inspection edge system 50 performs appearance re-inspection based on the marked battery image, it can focus on the candidate defect areas in the battery image more quickly and accurately for appearance re-inspection, thereby achieving efficient and accurate appearance re-inspection of the battery.

[0137] In one embodiment, the retesting edge system 50 includes several retesting edge devices. The retesting cloud system 30 is further configured to assign a battery retesting task to one of the retesting edge devices based on a scheduling algorithm. The scheduling algorithm is used to allocate battery retesting tasks to retesting edge devices that are idle or have fewer retesting tasks, enabling timely appearance retesting of batteries.

[0138] In other specific implementations, the re-testing cloud system 30 may also randomly send the battery re-testing task to a re-testing edge device, which is not limited here.

[0139] In one specific embodiment, the edge re-testing system 50 is configured to display a battery image to a re-testing operator and, in response to the re-testing operator's re-testing operations, generate a second test result for the battery. The edge re-testing system 50 intuitively displays the battery image to the user in real time, and the second test result is obtained based on the re-testing operator's re-testing operations. In other words, the edge re-testing system 50 achieves efficient and accurate appearance re-testing of batteries through the battery image display and interactive operation responses.

[0140] In one embodiment, the battery appearance inspection system 100 further includes a third battery identification device 13 provided at the sorting point 12. The third battery identification device 13 is configured to identify marking information of batteries passing through the sorting point 12. The sorting system 10 is further configured to use the marking information identified by the third battery identification device 13 to query the latest appearance inspection results of the batteries currently located at the sorting point 12.

[0141] When the batteries are transported to the sorting point 12 by the logistics line 11, the third battery identification device 13 located at the sorting point 12 will mark and identify the batteries to obtain the battery marking information. Before the sorting system 10 sorts the batteries, it will query the latest appearance inspection results of the batteries currently at the sorting point 12 based on the battery marking information identified by the third battery identification device 13 located at the sorting point 12.

[0142] In a specific embodiment, when the battery is transported to the sorting point 12 by the logistics line 11, the third battery identification device 13 provided at the sorting point 12 will mark and identify the battery to obtain the marking information of the battery; before the sorting system 10 sorts the battery, it will generate a mark to be queried based on the marking information of the battery identified by the third battery identification device 13 provided at the sorting point 12, and send it to the production execution system 40; the production execution system 40 can query the latest appearance inspection result of the battery according to the marking information of the battery, and feedback to the sorting system 10, so that the sorting system 10 can accurately sort the battery based on the latest appearance inspection result of the battery.

[0143] In one embodiment, the battery appearance inspection system 100 further includes a third battery identification device 13 disposed at the sorting point 12. The third battery identification device 13 is configured to identify the marking information of batteries passing through the sorting point 12. The battery appearance inspection system 100 further includes a production execution system 40. In response to identifying the marking information of batteries passing through the sorting point 12 by the third battery identification device 13, the sorting system 10 is further configured to sort the batteries passing through the sorting point 12 and provide a battery sorting notification to the production execution system 40. The battery sorting notification includes the marking information identified by the third battery identification device 13 and is configured to notify the production execution system 40 that the sorting status of the batteries corresponding to the marking information has been sorted. In other words, after the sorting system 10 sorts the batteries based on the latest appearance inspection results, it sends a battery sorting notification including the battery marking information to the production execution system 40. Upon receiving the battery sorting notification, the production execution system 40 marks the marking information as sorted, thereby recording the sorting status of the batteries corresponding to the marking information as sorted.

[0144] In a specific embodiment, the marking information of the battery is an ID code, and the third battery identification device 13 is an ID code identification device.

[0145] In one embodiment, the appearance inspection result of the battery is qualified or unqualified; the sorting system 10 performs sorting on the battery based on the latest appearance inspection result of the battery, specifically: in response to the latest appearance inspection result of the battery being qualified, the logistics line 11 is controlled to transport the battery to the qualified battery processing area 14; in response to the latest appearance inspection result of the battery being unqualified, the logistics line 11 is controlled to transport the battery to the unqualified battery processing area 15.

[0146] That is to say, when the latest appearance inspection result of the battery is qualified, the sorting system 10 will control the logistics line 11 to transport the battery to the qualified battery processing area 14, so that the qualified battery can be processed accordingly in the qualified battery processing area 14; when the latest appearance inspection result of the battery is unqualified, the sorting system 10 will control the logistics line 11 to transport the battery to the unqualified battery processing area 15, so that the unqualified battery can be processed accordingly in the unqualified battery processing area 15.

[0147] In one embodiment, the qualified battery processing area 14 is equipped with qualified battery processing equipment, and qualified batteries are processed using the qualified battery processing equipment in the qualified battery processing area 14. For example, the qualified battery processing equipment is a packaging machine, and qualified batteries are packaged using the packaging machine in the qualified battery processing area 14.

[0148] In a specific embodiment, there are several visual inspectors in the unqualified battery processing area 15. In the unqualified battery processing area 15, the several visual inspectors will re-evaluate or process the unqualified batteries.

[0149] In one embodiment, the appearance inspection result of the battery is qualified or unqualified; wherein, the battery appearance inspection system 100 further includes a qualified battery processing area 14 and an unqualified battery processing area 15, and the logistics line 11 includes a first logistics branch line 111 and a second logistics branch line 112 located after the sorting point 12. The first logistics branch line 111 is used to transport the qualified batteries with the latest qualified appearance inspection results at the sorting point 12 to the qualified battery processing area 14, and the qualified battery processing area 14 is used to provide the qualified batteries to qualified battery processing equipment for processing. The second logistics branch line 112 is used to transport the unqualified batteries with the latest unqualified appearance inspection results at the sorting point 12 to the unqualified battery processing area 15, and the unqualified battery processing area 15 is used to provide the unqualified batteries to visual inspection personnel for re-judgment or processing.
