Description

Technical Field

[0001] This application relates to the field of industrial manufacturing technologies, and particularly to a battery appearance detection system and method. Background Art

[0002] During the production process of batteries, an inspection machine is required to perform appearance inspection on the batteries. Due to the limitations of the inspection algorithm technical capabilities of the inspection machine, some batteries without appearance problems will be misjudged as having appearance problems, resulting in overkill of the batteries. Or, some batteries with appearance problems will be misjudged as having no appearance problems, resulting in missed killing of the batteries.

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

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

[0005] In a first aspect of this application, a battery appearance detection system is provided. The battery appearance detection system includes a sorting system, a vision detection system, a re-inspection cloud system, and a re-inspection edge system. The vision detection system is used to perform appearance inspection on the batteries passing through the logistics line, and obtain a first detection result for each battery according to the marking information of each battery. Among them, the vision detection system is arranged upstream of the logistics line. The re-inspection cloud system, in response to the first detection result of the battery meeting the re-inspection condition, instructs the re-inspection edge system to perform appearance re-inspection on the battery based on the battery appearance information provided by the vision detection system, and obtain a second detection result of the battery. The sorting system is used to, in response to the logistics line transporting the battery to the sorting point, obtain the latest appearance detection result of the battery. Among them, the sorting point is located downstream of the logistics line. In the case where there is currently no second detection result of the battery, the latest appearance detection result of the battery is the first detection result. In the case where there is currently a second detection result of the battery, the latest appearance detection result of the battery is the second detection result, and based on the latest appearance detection result of the battery, the battery is sorted. The case where there is currently no second detection result of the battery includes that the first detection result of the battery meets the re-inspection condition and when the logistics line transports the battery to the sorting point, no second detection result of the battery is generated.

[0006] Therefore, during the transportation of the battery on the logistics line, the battery will first pass through the visual inspection system installed upstream of the logistics line. The visual inspection system will perform an appearance inspection on the battery to obtain the first inspection result of the battery. After the battery passes through the visual inspection system installed upstream of the logistics line, the logistics line continues to transport the battery to the sorting point located downstream of the logistics line. At the same time, the rejudgment cloud system is responsible for instructing the rejudgment edge system to perform an appearance rejudgment on the battery when the first inspection result of the battery meets the rejudgment conditions. Therefore, during the transportation of the battery on the logistics line, an appearance rejudgment is performed on the battery whose first inspection result meets the rejudgment conditions. The appearance rejudgment action and the transportation action of the battery whose first inspection result meets the rejudgment conditions are carried out in parallel. That is, the transportation of the battery whose first inspection result meets the rejudgment conditions by the logistics line is continuous, and the appearance rejudgment of the battery whose first inspection result meets the rejudgment conditions will not affect the transportation rhythm of the logistics line for it. Therefore, it is possible to achieve an appearance rejudgment of the battery without affecting the transportation rhythm of the battery, meeting the high-rhythm production requirements of the production line. That is, it is possible to improve the accuracy of the appearance inspection of the battery to a certain extent without affecting the transportation rhythm of the battery and reduce the occurrence of misjudgment in the appearance inspection of the battery.

[0007] Among them, the battery appearance inspection system further includes a production execution system. The production execution system is communicatively connected to the visual inspection system, the rejudgment cloud system, and the sorting system. The production execution system is used to record the latest appearance inspection result of the battery based on the inspection result sent by the visual inspection system or the rejudgment cloud system, and feedback the latest appearance inspection result of the battery to the sorting system.

[0008] Therefore, the production execution system is used to record and feedback the latest appearance inspection result of the battery.

[0009] Among them, the production execution system is used to receive the first inspection information sent by the visual inspection system. The first inspection information includes the marking information of the battery and the first inspection result of the battery, and save the first inspection result as the latest appearance inspection result of the battery corresponding to the marking information. Receive the second inspection information sent by the rejudgment cloud system. The second inspection information includes the marking information of the battery and the second inspection result of the battery, and update the latest appearance inspection result of the battery using the second inspection information. And receive the marking information sent by the sorting system as the marking to be queried, and feedback the latest appearance inspection result of the battery corresponding to the marking to be queried to the sorting system.

[0010] Therefore, the production execution system is used to record, update, and feedback the latest appearance inspection result of the battery.

[0011] Among them, the re-judgment cloud system is also used to send second detection information when it is determined that the current preset conditions are met. The preset conditions include at least one of the following: the sorting system has not sorted the battery currently, 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 a 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 by 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, removing 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 marking information to be queried, so as to determine the latest appearance detection result of the battery corresponding to the marking information to be queried.

[0012] Therefore, if the second detection result of the battery is inconsistent with the first detection result of the battery, it indicates that the first detection result of the battery is incorrect. Then, the latest appearance detection result of the battery currently saved by the production execution system - the first detection result of the battery is incorrect, and the latest appearance detection result of the battery currently saved by the production execution system - the first detection result of the battery cannot truly reflect the appearance of the battery; since the sorting system sorts the battery based on the latest appearance detection result of the battery saved by the production execution system, therefore, whether to update the latest appearance detection result of the battery currently saved by the production execution system affects the sorting of the battery by the sorting system. And if the sorting system has not sorted the battery currently, then whether to update the latest appearance detection result of the battery currently saved by the production execution system will affect the sorting of the battery by the sorting system. At this time, the latest appearance detection result of the battery saved by the production execution system will be updated, and the latest appearance detection result of the battery will be updated to the second detection result of the battery, so that the latest appearance detection result of the battery saved by the production execution system can accurately reflect the true appearance of the battery. Then, when the sorting system sorts the battery, the production execution system can feedback the latest appearance detection result reflecting the true appearance of the battery to the sorting system, so that the sorting system can accurately sort the battery based on the latest appearance detection result of the battery.

[0013] Set a target appearance status flag for the marked information, so as to assign a classification identifier that can reflect the appearance of the battery corresponding to the marked information. Compared with the method of reflecting the appearance of the battery by recording the first detection result of the battery corresponding to the marked information, the memory consumption is reduced. In addition, when it is rejudged that the battery is not in the target appearance status, only the target appearance status flag set for the marked information needs to be removed. In addition, when the sorting system sorts the batteries, it can determine the latest appearance detection result of the battery by whether the target appearance status flag is currently set for the marked information of the battery, so as to be able to respond to the sorting system faster and improve the sorting efficiency of the batteries.

[0014] Among them, the production execution system is also used to record the sorting status of the battery as sorted in response to the sorting system executing the sorting of the battery; and / or, the production execution system is also used to detect that the battery in the battery container is taken out, record the container identifier of the battery container, and remind the sorting system, where the battery container is used to accommodate the batteries sorted by the sorting system; and / or, the visual inspection system is correspondingly arranged at the inspection station of the logistics line. The visual inspection system includes a first battery identification device. The first battery identification device is located at the feeding position of the inspection station and is used to identify the marked information of the battery transported on the logistics line. The visual inspection system is also used to send the marked information identified by the first battery identification device to the production execution system in response to the first battery identification device identifying the marked information of the battery; and / or, the visual inspection system is correspondingly arranged at the inspection station of the logistics line. The visual inspection system includes a second battery identification device. The second battery identification device is located at the discharging position of the inspection station and is used to identify the marked information of the battery transported on the logistics line. The visual inspection system is also used to send the marked information of the battery and the first detection result of the battery identified by the second battery identification device to the production execution system in response to the second battery identification device identifying the marked information of the battery.

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

[0016] After the battery is transported by the logistics line to the feeding position of the inspection station, the appearance inspection of the battery starts. That is, after the battery is transported by the logistics line to the feeding position of the inspection station, the state of the battery changes (enters the appearance inspection state). Since the first battery identification device is located at the feeding position of the inspection station, it can feedback the state change of the battery to the production execution system at the first time when the state of the battery changes.

[0017] After the battery is transported by the logistics line to the discharging position of the inspection station, the state of the battery changes (completes the appearance inspection state). Since the second battery identification device is located at the discharging position of the inspection station, it can feedback the state change of the battery to the production execution system at the first time when the state of the battery changes.

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

[0019] Therefore, since the visual inspection system completes the acquisition of battery images, the identification of battery markings, the appearance inspection of batteries, and the association of battery markings with the first inspection result during the transportation of batteries on the logistics line, a series of appearance inspection actions on the batteries and the transportation actions of the batteries are carried out in parallel. That is, the transportation of batteries on the logistics line is continuous, and a series of appearance inspection actions on the batteries will not affect the rhythm of the logistics line for transporting batteries; therefore, it is possible to perform an appearance inspection on the batteries without affecting the battery transportation rhythm, meeting the high-rhythm production requirements of the production line.

[0020] Among them, the visual inspection system is correspondingly arranged at the inspection station of the logistics line. The at least one battery identification device includes a first battery identification device and a second battery identification device. 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 the at least one battery identification device are located before the sorting point; and / or, specifically, the visual inspection system is used to perform a defect inspection on the batteries using the battery images to obtain a defect inspection result, and obtain a first inspection result of the batteries based on the defect inspection result. The first inspection result indicates whether the batteries are qualified.

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

[0022] Determine whether there are defects in the appearance of the batteries based on the defect inspection results of the battery images of the batteries.

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

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

[0025] Among them, the rejudgment cloud system is also used to perform the step of updating the second detection result of the battery as the latest appearance detection result of the battery when it is determined that the current preset conditions are met. 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.

[0026] Therefore, the preset conditions include that the second detection result of the battery is inconsistent with the first detection result of the battery; that is, when the second detection result of the battery is inconsistent with the first detection result of the battery, the second detection result of the battery is updated as the latest appearance detection result of the battery. The inconsistency between the second detection result of the battery and the first detection result of the battery indicates that the first detection result of the battery is incorrect. Then, the latest appearance detection result of the battery - the first detection result of the battery is incorrect, and the latest appearance detection result of the battery - the first detection result of the battery cannot truly reflect the appearance of the battery. At this time, updating the second detection result of the battery as the latest appearance detection result of the battery and updating the latest appearance detection result of the battery to the second detection result of the battery enable the latest appearance detection result of the battery to accurately reflect the appearance of the battery. If the second detection result of the battery is updated as the latest appearance detection result of the battery before the battery is transported to the sorting point on the logistics line, then when the sorting system sorts the battery, it can accurately sort the battery based on the latest appearance detection result of the battery that reflects the true appearance of the battery. If the second detection result of the battery is updated as the latest appearance detection result of the battery after the battery is transported to the sorting point on the logistics line, since the latest appearance detection result of the battery is updated, it is convenient for users to query and determine the true appearance of the battery later and is convenient for tracing.

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

[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 by 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 the 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 a battery image of the battery and the location information of the candidate defect areas of the battery in the battery image; the re-inspection cloud system is also used to mark the candidate defect areas of the battery image based on the location information of the candidate defect areas, and when assigning a re-inspection task to the re-inspection edge system, send the marked battery image to the re-inspection edge system; and / or, the re-inspection edge system includes several re-inspection edge devices, and the re-inspection cloud system is also used to assign the re-inspection task of the battery to one of the re-inspection edge devices based on a scheduling algorithm; and / or, the re-inspection edge system is used to display the battery image of the battery to the re-inspection personnel, and generate a second detection result of the battery in response to the re-inspection personnel's re-inspection operation.

[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-inspection edge system 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.

[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 time.

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

[0035] Among them, the battery appearance detection system further includes a third battery identification device disposed at the sorting point, and the third battery identification device is used to identify the marking information of the battery passing through the sorting point; among them, the sorting system is further used to query the latest appearance detection result of the battery currently located at the sorting point by using the marking information identified by the third battery identification device; and / or, the battery appearance detection system further includes a production execution system, and the sorting system is further used to respond to the marking information of the battery passing through the sorting point identified by using the third battery identification device, sort the battery passing through the sorting point, and feed back a battery sorted notification to the production execution system. The battery sorted notification includes the marking information identified by the third battery identification device, and is used to notify the production execution system to record the sorting status of the battery corresponding to the marking information as sorted.

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

[0037] After the sorting system sorts the battery based on the latest appearance detection result of the battery, it sends a battery sorted notification including the marking information of the battery to the production execution system to timely feed back the sorting status of the battery to the production execution system.

[0038] Among them, the appearance detection result of the battery is that the battery is qualified or unqualified; the sorting system executes sorting the battery based on the latest appearance detection result of the battery, including: in response to the latest appearance detection 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 detection 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 respectively set up to process qualified batteries and unqualified batteries respectively.

[0040] Among them, the appearance detection result of the battery is that the battery is qualified or unqualified; among them, the battery appearance detection system further includes a qualified battery processing area and an unqualified battery processing area. The logistics line includes a first logistics branch line and a second logistics branch line after the sorting point. The first logistics branch line is used to transport the qualified battery with the latest appearance detection result of being qualified at the sorting point to the qualified battery processing area, and the qualified battery processing area is used to provide the qualified battery processing equipment to process the qualified battery. The second logistics branch line is used to transport the unqualified battery with the latest appearance detection result of being unqualified at the sorting point to the unqualified battery processing area, and the unqualified battery processing area is used to provide the visual inspection personnel to rejudge or process the unqualified battery.

[0041] Therefore, different material branch lines will be set up to flow materials for qualified batteries and unqualified batteries respectively.

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

[0043] Therefore, a relatively long logistics line segment can be set between the vision detection system and the sorting point. If the logistics line segment between the vision detection system and the sorting point is long, then the time required for the battery to be transported to the sorting point by the logistics line is long, which can provide more time for the appearance rejudgment. Before the battery with the first detection result meeting the rejudgment condition is transported to the sorting point, there is enough time to complete the appearance rejudgment of the battery, so as to update the latest appearance detection result of the battery with the second detection result of the battery. As a result, the sorting system can accurately sort the battery based on the latest appearance detection result of the battery - the second detection result of the battery; in addition, due to more time for appearance rejudgment, the rejudgment accuracy can be improved and the misjudgment can be reduced.

[0044] The second aspect of the present application provides a method for battery appearance detection, which includes: performing appearance detection on the battery passing through the logistics line, and obtaining the first detection result of each battery according to the marking information of each battery; in response to the first detection result of the battery meeting the rejudgment condition, performing appearance rejudgment on the battery based on the battery appearance information of the battery to obtain the second detection result of the battery; and in response to the logistics line transporting the battery to the sorting point, obtaining the latest appearance detection result of the battery, where in the case that there is no second detection result of the battery currently, the latest appearance detection result of the battery is the first detection result, and in the case that there is a second detection result of the battery currently, the latest appearance detection result of the battery is the second detection result. The case where there is no second detection result of the battery currently includes that the first detection result of the battery meets the rejudgment condition and when the logistics line transports the battery to the sorting point, no second detection result of the battery is generated; sorting the battery based on the latest appearance detection result of the battery.

[0045] During the transportation of batteries on the logistics line, the visual inspection system will conduct an appearance inspection on the batteries to 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; meanwhile, the rejudgment cloud system is responsible for instructing the rejudgment edge system to conduct an appearance rejudgment on the batteries when the first inspection result of the batteries meets the rejudgment conditions. Therefore, during the transportation of batteries on the logistics line, the appearance rejudgment is carried out on the batteries whose first inspection results meet the rejudgment conditions, and the appearance rejudgment action and the transportation action on the batteries whose first inspection results meet the rejudgment conditions are carried out in parallel. That is, the transportation of the batteries whose first inspection results meet the rejudgment conditions by the logistics line continues, and the appearance rejudgment of the batteries whose first inspection results meet the rejudgment conditions will not affect the transportation rhythm of the logistics line for them; therefore, it is possible to achieve the appearance rejudgment of the batteries without affecting the battery transportation rhythm, meeting the high-rhythm production requirements of the production line. That is, without affecting the battery transportation rhythm, it is possible to improve the accuracy of the appearance inspection of the batteries to a certain extent and reduce the occurrence of misjudgment in the appearance inspection of the batteries.

[0046] Among them, after obtaining the first inspection result of each battery according to the marking information of each battery, the battery appearance inspection 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 inspection result of the battery is that the battery is in the target appearance state; after conducting an appearance rejudgment on the battery based on the battery appearance information of the battery to obtain the second inspection result of the battery, the battery appearance inspection method further includes: 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 marking information of the battery; obtaining the latest appearance inspection result of the battery, including: using the marking information of the battery located at the sorting point as the mark to be queried, and querying whether the mark to be queried currently has a target appearance state mark to determine the latest appearance inspection result of the battery corresponding to the mark to be queried.

[0047] Therefore, it is possible to record, update, and feedback the latest appearance inspection result of the battery through the production execution system.

[0048] In the above technical solution, during the transportation of the battery on the logistics line, the battery will first pass through the visual inspection system provided upstream of the logistics line. The visual inspection system will perform an appearance inspection on the battery to obtain the first inspection result of the battery. After the battery passes through the visual inspection system provided upstream of the logistics line, the logistics line continues to transport the battery to the sorting point located downstream of the logistics line. At the same time, the rejudgment cloud system is responsible for instructing the rejudgment edge system to perform an appearance rejudgment on the battery when the first inspection result of the battery meets the rejudgment conditions. Therefore, during the transportation of the battery on the logistics line, an appearance rejudgment is performed on the battery whose first inspection result meets the rejudgment conditions. The appearance rejudgment action and the transportation action for the battery whose first inspection result meets the rejudgment conditions are carried out in parallel. That is, the transportation of the battery whose first inspection result meets the rejudgment conditions by the logistics line continues, and the appearance rejudgment of the battery whose first inspection result meets the rejudgment conditions does not affect the transportation rhythm of the logistics line for it. Therefore, it is possible to achieve the appearance rejudgment of the battery without affecting the transportation rhythm of the battery, meeting the high-rhythm production requirements of the production line. That is, without affecting the transportation rhythm of the battery, the accuracy of the appearance inspection of the battery can be improved to a certain extent, and the occurrence of misjudgment in the appearance inspection of the battery can be reduced.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0051] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present application, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0052] In addition, if descriptions such as "first" and "second" are involved in the embodiments of the present application, the descriptions of "first", "second", etc. are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0053] To better understand the present application, the battery appearance detection system and the battery appearance detection method provided by the present application will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0054] Please refer to Figure 1 , Figure 1 FIG. is a schematic structural diagram of an embodiment of the battery appearance detection system provided by the present application. The present application provides a battery appearance detection system 100, and the battery appearance detection system 100 includes a sorting system 10, a vision detection system 20, a rejudgment cloud system 30, and a rejudgment edge system 50.

[0055] The vision detection system 20 is configured to perform appearance detection on the batteries passing through the logistics line 11, and obtain a first detection result for each battery according to the marking information of each battery. Among them, the vision detection system 20 is arranged upstream of the logistics line 11. By performing appearance detection on the batteries passing through the logistics line 11, the vision detection system 20 can determine whether there are defects in the appearance of the batteries. In addition, since the vision detection system 20 performs appearance detection on the batteries passing through the logistics line 11, the vision detection system 20 performs appearance detection on the batteries during the transportation process of the logistics line 11. Therefore, the transportation action and the appearance detection action of the batteries are carried out in parallel, that is, the transportation of the batteries by the logistics line 11 is continuous, and the appearance detection of the batteries passing through the logistics line 11 by the vision detection system 20 will not affect the rhythm of the battery transportation by the logistics line 11; therefore, it is possible to perform appearance detection on the batteries without affecting the battery transportation rhythm and meet the high-rhythm production requirements of the production line, that is, it is possible to determine whether there are defects in the appearance of the batteries without affecting the battery transportation rhythm.

[0056] When the first detection result of the battery meets the retest condition, the retest cloud system 30 instructs the retest edge system 50 to perform an appearance retest on the battery based on the battery appearance information provided by the vision detection system 20, and obtains the second detection result of the battery. Since the appearance detection ability of the vision detection system 20 is limited, there may be misjudgments in the appearance detection of the battery. Therefore, when the first detection result of the battery meets the retest condition, an appearance retest is performed on the battery whose first detection result meets the retest condition based on the battery appearance information provided by the vision detection system 20, so as to further review the appearance of the battery whose first detection result meets the retest condition, which improves the accuracy of the battery appearance detection to a certain extent and reduces the occurrence of misjudgments in the battery appearance detection. In addition, the retest cloud system 30 is responsible for instructing the retest edge system 50 to perform an appearance retest on the battery when the first detection result of the battery meets the retest condition, that is, responsible for sending the retest task of the battery to the retest edge system 50. The retest edge system 50 is responsible for the specific execution of the battery appearance retest. The retest cloud system 30 and the retest edge system 50 cooperate with each other and have clear division of labor, realizing accurate and efficient retest of the battery appearance.

[0057] The sorting system 10 is used to obtain the latest appearance detection result of the battery in response to the logistics line 11 transporting the battery to the sorting point 12, where the sorting point 12 is located downstream of the logistics line 11. In the case where there is no second detection result of the battery currently, the latest appearance detection result of the battery is the first detection result. In the case where there is a second detection result of the battery currently, the latest appearance detection result of the battery is the second detection result, and the battery is sorted based on the latest appearance detection result of the battery. The case where there is no second detection result of the battery currently includes that the first detection result of the battery meets the retest condition and when the logistics line 11 transports the battery to the sorting point 12, no second detection result of the battery is generated.

[0058] In one embodiment, the case where there is no second detection result of the battery currently also includes that the first detection result of the battery does not meet the retest condition. Since the first detection result of the battery does not meet the retest condition, there is no need to perform an appearance retest on this battery, and thus there is no second detection result obtained from the appearance retest on it.

[0059] During the transportation of the battery on the logistics line 11, the battery will first pass through the vision inspection system 20 provided upstream of the logistics line 11. The vision inspection system 20 will perform an appearance inspection on the battery to obtain the first inspection result of the battery. After the battery passes through the vision inspection system 20 provided upstream of the logistics line 11, the logistics line 11 continues to transport the battery to transport it to the sorting point 12; at the same time, the rejudgment cloud system 30 is responsible for instructing the rejudgment edge system 50 to perform an appearance rejudgment on the battery when the first inspection result of the battery meets the rejudgment conditions. Therefore, during the transportation of the battery by the logistics line 11, an appearance rejudgment is performed on the battery whose first inspection result meets the rejudgment conditions. Therefore, the appearance rejudgment action and the transportation action on the battery whose first inspection result meets the rejudgment conditions are carried out in parallel. That is, the transportation of the battery whose first inspection result meets the rejudgment conditions by the logistics line 11 is continuous, and the appearance rejudgment of the battery whose first inspection result meets the rejudgment conditions will not affect the rhythm of the logistics line 11 in transporting it; therefore, it is possible to perform an appearance rejudgment on the battery without affecting the battery transportation rhythm, meeting the high-rhythm production requirements of the production line. That is, it is possible to improve the accuracy of the appearance inspection of the battery to a certain extent and reduce the occurrence of misjudgment in the appearance inspection of the battery without affecting the battery transportation rhythm.

[0060] Since it is during the process of the sorting system 10 controlling the transportation of the battery on the logistics line 11 that the vision inspection system 20 performs an appearance inspection on the battery to obtain the first inspection result of the battery; and since it is during the process of the sorting system 10 controlling the transportation of the battery on the logistics line 11 that the rejudgment cloud system 30, when determining that the first inspection result of the battery meets the rejudgment conditions, instructs the rejudgment edge system 50 to perform an appearance rejudgment on the battery based on the battery appearance information provided by the vision inspection system 20. Therefore, the sorting system 10 works in parallel with the vision inspection system 20, the rejudgment cloud system 30, and the rejudgment edge system 50.

[0061] By performing an appearance inspection on the battery passing through the logistics line 11, the vision inspection system 20 can determine whether there are defects in the appearance of the battery. In addition, since the vision inspection system 20 and the sorting system 10 work in parallel, the appearance inspection of the battery passing through the logistics line 11 by the vision inspection system 20 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 transportation of the battery to the sorting point 12 by the logistics line 11 and performing battery sorting based on the latest appearance inspection result of the battery; that is, it is possible to perform an appearance inspection on the battery without affecting the transportation and sorting rhythms of the battery, meeting the high-rhythm production requirements of the production line.

[0062] When the rejudgment cloud system 30 determines that the first detection result of the battery meets the rejudgment condition, it instructs the rejudgment edge system 50 to perform an appearance rejudgment on the battery based on the battery appearance information provided by the vision detection system 20, so as to further review the appearance of the battery whose first detection result meets the rejudgment condition, which improves the accuracy of the battery appearance detection to a certain extent and reduces the occurrence of misjudgment in the battery appearance detection. In addition, since the rejudgment cloud system 30, the rejudgment edge system 50, and the sorting system 10 work in parallel, when the rejudgment cloud system 30 determines that the first detection result of the battery meets the rejudgment condition and instructs the rejudgment edge system 50 to perform an appearance rejudgment on the battery, and the rejudgment edge system 50 performs an appearance rejudgment on the battery, it will not affect the sorting system 10 from controlling the logistics line 11 to transport the battery to the sorting point 12 and the sorting system 10 from responding to the logistics line 11 transporting the battery to the sorting point 12 and sorting the battery based on the latest appearance detection result of the battery; therefore, it is possible to perform an appearance rejudgment on the battery without affecting the transportation and sorting rhythm of the battery, meeting the high-rhythm production requirements of the production line, that is, it is possible to improve the accuracy of the battery appearance detection to a certain extent without affecting the transportation and sorting rhythm of the battery and reduce the occurrence of misjudgment in the battery appearance detection.

[0063] If the first detection result of a battery meets the rejudgment condition, then when the rejudgment cloud system 30 determines that the first detection result of the battery meets the rejudgment condition, it instructs the rejudgment edge system 50 to perform an appearance rejudgment on the battery based on the battery appearance information provided by the vision detection 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, there is a second detection result of the battery at this time, then the latest appearance detection result of the battery is the second detection result of the battery; then, when the sorting system 10 controls the logistics line 11 to transport the battery to the sorting point 12, it will obtain the latest appearance detection result of the battery - the second detection result of the battery, and sort the battery according to the latest appearance detection result of the battery - the second detection result of the battery. If, when the sorting system 10 controls the logistics line 11 to transport the battery to the sorting point 12, there is no second detection result of the battery at this time and the second detection result of the battery cannot be obtained, then the latest appearance detection result of the battery is the first detection result of the battery; and in this case, when the sorting system 10 controls the logistics line 11 to transport the battery to the sorting point 12, it will obtain the latest appearance detection result of the battery - the first detection result of the battery, and sort the battery according to the latest appearance detection result of the battery - the first detection result of the battery, instead of waiting for the rejudgment edge system 50 to complete the appearance rejudgment of the battery before sorting it.

[0064] That is to say, the sorting system 10 and the recheck edge system 50 work in parallel. When the battery with the first detection result meeting the recheck condition is transported to the sorting point 12, regardless of whether there is a second detection result of the battery at present, the sorting system 10 will sort the battery and will not wait until there is a second detection result of the battery to sort it when there is no second detection result of the battery at present.

[0065] In addition, if the first detection result of a battery does not meet the recheck condition and the appearance recheck of the battery does not need to be performed, the sorting system 10 will control 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, the latest appearance detection result of the battery, that is, the first detection result of the battery, will be obtained, and the battery will be sorted according to the latest appearance detection result of the battery, that is, the first detection result of the battery.

[0066] For example, as Figure 1 shown, the sorting system 10 controls the logistics line 11 to transport the battery A. During the process of the sorting system 10 controlling the logistics line 11 to transport the battery A, the vision detection system 20 will first perform an appearance detection on the battery A passing through the logistics line 11 to determine whether there are defects in the appearance of the battery A; since the vision detection system 20 and the sorting system 10 work in parallel, the appearance detection of the battery A passing through the logistics line 11 by the vision detection system 20 will not affect the rhythm of the sorting system 10 controlling the logistics line 11 to transport the battery A to the sorting point 12 and the sorting system 10 responding to the transportation of the battery A to the sorting point 12 by the logistics line 11 and sorting the battery A based on the latest appearance detection result of the battery A; therefore, it is possible to realize the appearance detection of the battery A without affecting the transportation and sorting rhythm of the battery A, meeting the high-rhythm production requirements of the production line.

[0067] After the appearance of Battery A is inspected by the visual inspection system 20, if the first inspection result of Battery A meets the reinspection condition, then the reinspection cloud system 30 will, when determining that the first inspection result of the battery meets the reinspection condition, instruct the reinspection edge system 50 to conduct an appearance reinspection on Battery A based on the battery appearance information provided by the visual inspection system 20; meanwhile, 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, there is a second inspection result of Battery A at this time, 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 according to 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, there is no second inspection result of Battery A at this time, then the second inspection result of Battery A cannot be obtained, and the latest appearance inspection result of Battery A at this time is the first inspection result of Battery A; and 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 according to the latest appearance inspection result of Battery A - the first inspection result of Battery A, instead of waiting until there is a second inspection result of Battery A before sorting it.

[0068] That is to say, if the first inspection result of Battery A meets the reinspection condition, when Battery A is transported to the sorting point 12 by the logistics line 11, regardless of whether there is a second inspection result of Battery A, the sorting system 10 will sort Battery A. The sorting system 10 and the reinspection edge system 50 work in parallel. The appearance reinspection of Battery A by the reinspection 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 system 10 responding to the logistics line 11 transporting Battery A to the sorting point 12 and sorting the battery based on the latest appearance inspection result of Battery A; therefore, it is possible to conduct an appearance reinspection on Battery A without affecting the transportation and sorting rhythm of Battery A, meeting the high-rhythm production requirements of the production line.

[0069] In one embodiment, the length of the logistics line segment between the logistics line 11 and the sorting point 12 in the visual inspection system 20 is greater than a preset length. That is to say, a relatively long logistics line segment can be set between the visual inspection system 20 and the sorting point 12. Since the logistics line segment between the visual inspection system 20 and the sorting point 12 is long, the time required for the battery to be transported by the logistics line 11 to the sorting point 12 is long, which can provide more time for the re-inspection of the appearance. Before the battery with the first inspection result meeting the re-inspection conditions is transported to the sorting point 12, there is enough time to complete the re-inspection of the appearance of the battery, so as to update the latest appearance inspection result of the battery by using the second inspection result of the battery, so that the sorting system 10 can accurately sort the battery based on the latest appearance inspection result of the battery, that is, the second inspection result of the battery. In addition, since there is more time for the re-inspection of the appearance, the accuracy of the re-inspection can be improved and the misjudgment can be reduced.

[0070] Among them, the size of the preset length is not limited and can be specifically set according to actual usage needs.

[0071] In one embodiment, the first inspection result of the battery is that the battery is qualified or unqualified, and the re-inspection condition is that the first inspection result is that the battery is in the target appearance state, and the target appearance state is the unqualified state. Due to the limited appearance inspection ability of the visual inspection system 20, some qualified batteries may be misjudged as unqualified batteries, resulting in overkill. The re-inspection condition is that the first inspection result is that the battery is in the unqualified state, so the batteries meeting the re-inspection conditions are unqualified batteries with the first inspection result being unqualified. By re-inspecting the appearance of the unqualified batteries with the first inspection result being unqualified, the accuracy of the appearance inspection of the battery can be improved to a certain extent and the overkill rate can be reduced.

[0072] In other embodiments, the first inspection result of the battery is that the battery is qualified or unqualified, and the re-inspection condition is that the first inspection result is that the battery is in the target appearance state, and the target appearance state is the qualified state. Due to the limited appearance inspection ability of the visual inspection system 20, some unqualified batteries may be misjudged as qualified batteries, resulting in missed killing. The re-inspection condition is that the first inspection result is that the battery is in the qualified state, so the batteries meeting the re-inspection conditions are qualified batteries with the first inspection result being qualified. By re-inspecting the appearance of the qualified batteries with the first inspection result being qualified, the accuracy of the appearance inspection of the battery can be improved to a certain extent and the missed killing rate can be reduced.

[0073] In one embodiment, the battery appearance inspection system 100 further includes a production execution system 40. The production execution system 40 is communicatively connected to the visual inspection system 20, the re-inspection cloud system 30, and the sorting system 10. The production execution system 40 is configured to record the latest appearance inspection result of the battery based on the inspection result sent by the visual inspection system 20 or the re-inspection cloud system 30, and feedback the latest appearance inspection result of the battery to the sorting system 10.

[0074] That is to say, the production execution system 40 communicates and interacts with the vision inspection system 20. After the vision 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 vision 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 also communicates and interacts with the rejudgment cloud system 30. After the rejudgment edge system 50 performs an appearance rejudgment on the battery, it will send the second inspection result of the battery to the rejudgment cloud system 30, and the rejudgment cloud system 30 will send the inspection result to the production execution system 40; after receiving the inspection result sent by the rejudgment 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 also communicates and interacts 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.

[0075] That is, the production execution system 40 realizes the recording and feedback of the latest appearance inspection result of the battery.

[0076] It should be noted that if the first test result of a battery meets the retest conditions, but when the battery is transported to the sorting point 12 on the logistics line 11, the second test result of the battery is not generated, including the following situations: The first situation is that the retest edge system 50 has not completed the appearance retest of the battery. Since the retest edge system 50 has not completed the appearance retest of the battery, the retest cloud system 30 cannot obtain the second test result of the battery, and thus the production execution system 40 cannot obtain the second test result of the battery. Therefore, when the retest edge system 50 has not completed the appearance retest of the battery, the second test result of the battery is not generated, resulting in the current non-existence of the second test result of the battery. The latest appearance test result of the battery is the first test result of the battery, and the latest appearance test result of the battery recorded by the production execution system 40 is the first test result of the battery. The second situation is that the retest edge system 50 has completed the appearance retest of the battery, but the retest edge system 50 has not yet sent the second test result of the battery to the retest cloud system 30. Therefore, the retest cloud system 30 cannot obtain the second test result of the battery, and the production execution system 40 cannot obtain the second test result of the battery. Therefore, when the retest edge system 50 has completed the appearance retest of the battery, but the retest edge system 50 has not yet sent the second test result of the battery to the retest cloud system 30, the second test result of the battery is not generated, resulting in the current non-existence of the second test result of the battery. The latest appearance test result of the battery is the first test result of the battery, and the latest appearance test result of the battery recorded by the production execution system 40 is the first test result of the battery. The third situation is that the retest edge system 50 has completed the appearance retest of the battery and the retest edge system 50 has sent the second test result of the battery to the retest cloud system 30, but the retest cloud system 30 has not yet sent the second test result of the battery to the production execution system 40. The latest appearance test result of the battery recorded by the production execution system 40 is the first test result of the battery. Therefore, when the retest edge system 50 has completed the appearance retest of the battery and the retest edge system 50 has sent the second test result of the battery to the retest cloud system 30, but the retest cloud system 30 has not yet sent the second test result of the battery to the production execution system 40, the second test result of the battery is not generated, resulting in the current non-existence of the second test result of the battery. The latest appearance test result of the battery is the first test result of the battery.

[0077] It should be noted that the production execution system described in this article consists of a comprehensive dynamic software system developed by IT.

[0078] In a specific embodiment, the production execution system 40 is used to receive the first detection information sent by the vision detection system 20. The first detection information includes the marking information of the battery and the first detection result of the battery, and saves the first detection result as the latest appearance detection result of the battery corresponding to the marking information.

[0079] Specifically, the production execution system 40 communicates with the vision detection system 20. After the vision detection system 20 performs an appearance detection on the battery passing through the logistics line 11 and obtains the first detection result of the battery, it sends the first detection information including the marking information of the battery and the first detection result of the battery to the production execution system 40. After the production execution system 40 receives the first detection information including the marking information of the battery and the first detection result of the battery sent by the vision detection system 20, it saves the first detection result of the battery and the marking information of the battery, and uses the first detection result as the latest appearance detection result of the battery corresponding to the marking information.

[0080] The marking information of the battery serves as the unique "digital ID card" of the battery. Through the marking information of the battery, the latest appearance detection results of different batteries can be distinguished. On the one hand, the latest appearance detection results of the battery can be accurately fed back to the sorting system 10 subsequently; on the other hand, the appearance detection results of the batteries whose appearance detection results need to be updated can be accurately updated.

[0081] The production execution system 40 is used to receive the second detection information sent by the rejudgment cloud system 30. The second detection information includes the marking information of the battery and the second detection result of the battery, and uses the second detection information to update the latest appearance detection result of the battery.

[0082] Specifically, after the rejudgment edge system 50 performs an appearance rejudgment on the battery whose first detection result meets the rejudgment condition and obtains the second detection result of the battery, it feeds back the second detection result of the battery to the rejudgment cloud system 30. The production execution system 40 communicates with the rejudgment cloud system 30, and the rejudgment cloud system 30 sends the second detection information including the marking information of the battery and the second detection result of the battery to the production execution system 40. After the production execution system 40 receives the second detection information including the marking information of the battery and the second detection result of the battery sent by the rejudgment cloud system 30, it uses it to update the latest appearance detection result of the battery.

[0083] The production execution system 40 is used to receive the marking information sent by the sorting system 10 as the marking to be queried, and feeds back the latest appearance detection result of the battery corresponding to the marking to be queried to the sorting system 10.

[0084] Specifically, the production execution system 40 communicates with the sorting system 10. Before the sorting system 10 sorts the batteries, it sends a query mark to be queried to the production execution system 40, and the query mark to be queried is the marking information of the battery. The production execution system 40 can query the latest appearance inspection result of the battery based on the marking information of the battery and feedback it 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.

[0085] That is, the production execution system 40 is used to record, update, and feedback the latest appearance inspection result of the battery.

[0086] Among them, the marking information of the battery can be the ID code of the battery.

[0087] In a specific embodiment, the rejudgment cloud system 30 is further configured to send second detection information when it is determined that the current preset conditions are met. The preset conditions include 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.

[0088] The preset conditions include that the second detection result of the battery is inconsistent with the first detection result of the battery; that is, when the second detection result of the battery is inconsistent with the first detection result of the battery, the rejudgment cloud system 30 sends the second detection information to the production execution system 40, so that the production execution system 40 uses the second detection information to update the latest appearance detection result of the battery. The inconsistency between the second detection result of the battery and the first detection result of the battery indicates that the first detection result detected by the vision detection system 20 for the battery is incorrect. Then, the latest appearance detection result of the battery currently saved by the production execution system 30 - the first detection result of the battery is incorrect, and the latest appearance detection result of the battery currently saved by the production execution system 40 - the first detection result of the battery cannot truly reflect the appearance of the battery. At this time, the latest appearance detection result of the battery saved by the production execution system 40 will be updated, and the latest appearance detection result of the battery will be updated to the second detection result of the battery, so that the latest appearance detection result of the battery saved by the production execution system 40 can accurately reflect the appearance of the battery. If the update of the latest appearance detection result of the battery saved by the production execution system 40 is before the logistics line 11 transports the battery to the sorting point 12, then when the sorting system 10 sorts the battery, the production execution system 40 can feedback the latest appearance detection result reflecting the true 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 detection result of the battery. If the update of the latest appearance detection result of the battery saved by the production execution system 40 is after the logistics line 11 transports the battery to the sorting point 12, due to the update of the latest appearance detection result of the battery, it is convenient for users to query and determine the true appearance of the battery later and is convenient for tracing.

[0089] The preset conditions include that the sorting system 10 is not currently sorting the battery. That is, when the sorting system 10 is not currently sorting the battery, the second detection information is sent to the production execution system 40 so that the production execution system 40 can use it to update the latest appearance detection result of the battery. Since the sorting system 10 sorts the battery based on the latest appearance detection result of the battery saved by the production execution system 40, whether to update the latest appearance detection result of the battery currently saved by the production execution system 40 affects the sorting of the battery by the sorting system 10. If the sorting system 10 has currently sorted the battery, then whether to update the latest appearance detection result of the battery currently saved by the production execution system 40 no longer affects the sorting of the battery by the sorting system 10, and there is no need to update the latest appearance detection result of the battery currently saved by the production execution system 40. If the sorting system 10 is not currently sorting the battery, then whether to update the latest appearance detection result of the battery currently saved by the production execution system 40 will affect the sorting of the battery by the sorting system 10, and it is necessary to update the latest appearance detection result of the battery currently saved by the production execution system 40, so that the subsequent sorting system 10 can accurately sort the battery.

[0090] The preset conditions include that 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; that is, when 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, the second detection information is sent to the production execution system 40 so that the production execution system 40 can use it to update the latest appearance detection result of the battery. The inconsistency between the second detection result of the battery and the first detection result of the battery indicates that the first detection result of the battery is incorrect. Then, the latest appearance detection result of the battery currently saved by the production execution system 40 - the first detection result of the battery is incorrect, and the latest appearance detection result of the battery currently saved by the production execution system 40 - the first detection 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 detection result of the battery saved by the production execution system 40, whether to update the latest appearance detection result of the battery currently saved by the production execution system 40 affects the sorting of the battery by the sorting system 10. If the sorting system 10 is not currently sorting the battery, then whether to update the latest appearance detection result of the battery currently saved by the production execution system 40 will affect the sorting of the battery by the sorting system 10. At this time, the latest appearance detection result of the battery saved by the production execution system 40 will be updated, and the latest appearance detection result of the battery is updated to the second detection result of the battery, so that the latest appearance detection result of the battery saved by the production execution system 40 can accurately reflect the true appearance of the battery. Then, when the sorting system 10 sorts the battery, the production execution system 40 can feedback the latest appearance detection result reflecting the true 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 detection result of the battery.

[0091] Specifically, after the rejudgment edge system 50 performs an appearance rejudgment on the battery whose first detection result meets the rejudgment condition and obtains the second detection result of the battery, it will feedback the second detection result of the battery to the rejudgment cloud system 30; the production execution system 40 will communicate with the rejudgment cloud system 30. The rejudgment cloud system 30 determines whether the second detection result of the battery is consistent with the first detection result of the battery, and when it determines that the second detection result of the battery is inconsistent with the first detection result of the battery, it sends a query instruction including the marking information of the battery 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 feedbacks the query result to the rejudgment cloud system 30; then, the rejudgment cloud system 30 determines whether the battery has been sorted according to the query result feedback by the production execution system 40, and when it determines that the battery has not been sorted by the sorting system 10 currently, it sends second detection information including the marking information of the battery and the second detection result of the battery to the production execution system 40; after the production execution system 40 receives the second detection information including the marking information of the battery and the second detection result of the battery sent by the rejudgment cloud system 30, it updates the latest appearance detection result of the battery by using the same.

[0092] In a specific embodiment, the rejudgment condition is: the first detection result is that the battery is in the target appearance state; the production execution system 40 executes to save the first detection result as the latest appearance detection result corresponding to the marking information, including: recording the marking information of the battery and setting a target appearance state mark for the marking information of the battery.

[0093] Specifically, the production execution system 40 will communicate with the vision detection system 20. After the vision detection system 20 performs an appearance detection on the battery passing through the logistics line 11 and obtains the first detection result of the battery, it will send the first detection information including the marking information of the battery and the first detection result of the battery to the production execution system 40; after the production execution system 40 receives the first detection information including the marking information of the battery and the first detection result of the battery sent by the vision detection system 20, based on the first detection result of the battery, it determines whether the battery is in the target appearance state, and when it determines that the battery is in the target appearance state, it records the marking information of the battery and sets a target appearance state mark for the marking information of the battery. In addition, when the production execution system 40 determines based on the first detection result of the battery that the battery is not in the target appearance state, it only records the marking information of the battery.

[0094] 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 an unqualified state. After the visual inspection system 20 performs an appearance inspection on battery A passing through the logistics line 11 and obtains that the first inspection result of battery A is an unqualified battery, the first inspection information including the marking information of battery A and the first inspection result of battery A will be sent 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 in an unqualified state based on the first inspection result of battery A, records the marking information of battery A, and sets a target appearance state mark for the marking information.

[0095] The production execution system 40 uses the second detection information to update the latest appearance detection result of the battery, including: 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 battery marking information.

[0096] 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-judged 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-judged battery is not in the target appearance state, the target appearance state mark of the battery marking information is removed.

[0097] 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 an unqualified state. 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, based on the second test result of battery A, it is determined that the re-judged battery A is not in an unqualified state, and the target appearance state mark of the marking information of battery A is removed.

[0098] For another example, the first detection result of battery A is that the battery is unqualified, and the rejudgment condition is that the first detection result is that the battery is in the target appearance state, and the target appearance state is the unqualified state. After the appearance rejudgment of battery A is performed and the second detection result of battery A is that the battery is unqualified, the second detection information including the marking information of battery A and the second detection result of battery A will not be sent to the production execution system 40, and the production execution system 40 will not cancel the target appearance state marking of the marking information of battery A. Or, after the appearance rejudgment of battery A is performed and the second detection result of battery A is that the battery is unqualified, the second detection information including the marking information of battery A and the second detection result of battery A will be sent to the production execution system 40; after the production execution system 40 receives the second detection information including the marking information of battery A and the second detection result of battery A sent by the rejudgment cloud system 30, based on the second detection result of battery A, it is determined that the rejudgment of battery A is still in the unqualified state, and the target appearance state marking of the marking information of battery A is not cancelled.

[0099] The sorting system 10 is further configured to query the production execution system 40 to determine whether the target appearance state marking 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.

[0100] Specifically, the production execution system 40 will communicate with the sorting system 10. Before the sorting system 10 sorts the battery, it will send the mark to be queried to the production execution system 40, and 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 state marking according to the marking information of the battery and feedback it to the sorting system 10; the sorting system 10 sorts it based on whether the marking information of the battery is set with the target appearance state marking.

[0101] For example, the first detection result of battery A is that the battery is unqualified, and the rejudgment condition is that the first detection result is that the battery is in the target appearance state, and the target appearance state is the unqualified state. After performing an appearance rejudgment on battery A and obtaining the second detection result of battery A as qualified, the second detection information including the marking information of battery A and the second detection result of battery A will be sent to the production execution system 40; after the production execution system 40 receives the second detection information including the marking information of battery A and the second detection result of battery A sent by the rejudgment cloud system 30, based on the second detection result of battery A, the target appearance state marking of the marking information of battery A will be removed. When the sorting system 10 needs to sort battery A, a query mark to be queried will be sent to the production execution system 40, and the query mark to be queried is the marking information of battery A; the production execution system 40 queries the marking information of battery A based on the received query mark to be queried and finds that it is not set with a target appearance state marking 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.

[0102] For another example, the first detection result of battery A is that the battery is unqualified, and the rejudgment condition is that the first detection result is that the battery is in the target appearance state, and the target appearance state is the unqualified state. After performing an appearance rejudgment on battery A and obtaining the second detection result of battery A as unqualified, the second detection information including the marking information of battery A and the second detection 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 marking of the marking information of battery A. When the sorting system 10 needs to sort battery A, a query mark to be queried will be sent to the production execution system 40, and the query mark to be queried is the marking information of battery A; the production execution system 40 queries the marking information of battery A based on the received query mark to be queried and finds that it is set with a target appearance state marking 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.

[0103] Setting a target appearance state marking for the marking information to assign a classification identifier that can reflect its appearance to the battery corresponding to the marking information reduces memory consumption compared to the method of recording the appearance detection results of the battery corresponding to the marking information to reflect its appearance. In addition, when rejudging that the battery is not in the target appearance state, only the target appearance state marking of the marking information needs to be removed. In addition, when the sorting system 10 sorts the battery, it can determine the latest appearance detection result of the battery based on whether the marking information of the battery is currently set with a target appearance state marking, so as to be able to respond to the sorting system 10 faster and improve the sorting efficiency of the battery.

[0104] In other specific embodiments, when the rejudgment cloud system 30 determines that the second detection result of the battery is inconsistent with the first detection result of the battery, it may also send a marking cancellation instruction including the marking information of the battery to the production execution system 40, so that after receiving the marking cancellation instruction, the production execution system 40 cancels the target appearance status marking of the marking information.

[0105] In one specific embodiment, the production execution system 40 is further configured to record the sorting status of the battery as sorted in response to the sorting system 10 performing sorting on the battery. Specifically, after the sorting system 10 sorts the battery based on the latest appearance detection result of the battery, it sends a battery sorted notification including the marking information of the battery to the production execution system 40; after the production execution system 40 receives the battery sorted notification, it marks the marking information as sorted to record the sorting status of the battery corresponding to the marking information as sorted.

[0106] In one specific embodiment, the production execution system 40 is further configured to detect that the battery in the battery container is taken out, record the container identifier of the battery container, and remind the sorting system 10, where the battery container is used to accommodate the battery sorted by the sorting system 10.

[0107] In a specific embodiment, the vision detection system 20 is correspondingly arranged at the detection station (not shown in the figure) of the logistics line 11. The vision detection system 20 includes a first battery identification device 21. The first battery identification device 21 is located at the feeding position of the detection station (not shown in the figure) and is used to identify the marking information of the battery transported by the logistics line 11. The vision detection system 20 is further configured to send the marking information identified by the first battery identification device 21 to the production execution system 40 in response to the first battery identification device 21 identifying the marking information of the battery. That is to say, the first battery identification device 21 is arranged at the feeding position of the detection station of the logistics line 11. When the battery is transported by the logistics line 11 to the feeding position of the detection station, the first battery identification device 21 will perform marking identification on the battery to obtain the marking information of the battery. Then, the vision detection 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 feeding position of the detection station and the appearance inspection of the battery starts after the battery is transported by the logistics line 11 to the feeding position of the detection station, 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 a third identifier for the marking information to indicate the entry into the appearance inspection state, so as to facilitate the user to understand the current state of the battery. In addition, the appearance inspection of the battery starts after the battery is transported by the logistics line 11 to the feeding position of the detection station. That is, after the battery is transported by the logistics line 11 to the feeding position of the detection station, the state of the battery changes (entering the appearance inspection state). Since the first battery identification device 21 is located at the feeding position of the detection station, it can feedback the state change of the battery to the production execution system 40 at the first moment when the state of the battery changes.

[0108] 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.

[0109] In a specific embodiment, the vision detection system 20 is correspondingly arranged at the detection station of the logistics line 11. The vision detection system 20 includes a second battery identification device 22. The second battery identification device 22 is located at the discharging position of the detection station (not shown in the figure) and is used to identify the marking information of the battery transported by the logistics line 11. The vision detection system 20 is further configured to send the marking information of the battery identified by the second battery identification device 22 and the first detection result of the battery to the production execution system 40 in response to the second battery identification device 22 identifying the marking information of the battery.

[0110] That is to say, a second battery identification device 22 is provided at the discharging position of the inspection station on the logistics line 11. When the battery is transported by the logistics line 11 to the discharging position of the inspection station, the second battery identification device 22 will perform marking identification on the battery to obtain the marking information of the battery. Then, the vision 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.

[0111] The marking information of the battery serves as the unique "digital ID card" of the battery. Through the marking information of the battery, the latest appearance inspection results of different batteries can be distinguished. On the one hand, the latest appearance inspection result of the battery can be quickly located subsequently, and the latest appearance inspection result of the battery can be accurately fed back to the sorting system 10. On the other hand, the appearance inspection result of the battery that needs to be updated can be accurately updated. In addition, since the second battery identification device 22 is located at the discharging position of the inspection station, and the appearance inspection of the battery is completed after the battery is transported by the logistics line 11 to the discharging position of the inspection station, therefore, after the production execution system 40 receives the marking information of the battery identified by the second battery identification device 22, a fourth identifier indicating the completion of the appearance inspection status will also be marked for the marking information, so as to facilitate the user to understand the current status of the battery. Moreover, the appearance inspection of the battery is completed after the battery is transported by the logistics line 11 to the discharging position of the inspection station, that is, after the battery is transported by the logistics line 11 to the discharging position of the inspection station, the status of the battery changes (completion of the appearance inspection status). Since the second battery identification device 22 is located at the discharging position of the inspection station, the change in the status of the battery can be fed back to the production execution system 40 at the first time when the status of the battery changes.

[0112] 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.

[0113] In an embodiment, the vision inspection system 20 includes an image acquisition device (not shown in the figure) and at least one battery identification device. The battery identification device is used to identify the marking information of the battery transported by the logistics line 11, and the image acquisition device is used to acquire the battery image of the battery transported on the logistics line 11. The vision inspection system 20 is specifically configured to perform appearance inspection on the battery using the battery image to obtain the first inspection result of the battery, and associate the first inspection result of the battery with the corresponding marking information.

[0114] That is to say, during the transportation of the battery by the logistics line 11, the image acquisition device of the vision detection system 20 acquires the battery image of the battery, and the battery identification device of the vision detection system 20 identifies the marking information of the battery. The vision detection system 20 performs an appearance inspection on the battery based on the battery image acquired by the image acquisition device to obtain the first inspection result of the battery, so as to determine whether there are defects in the appearance of the battery; in addition, the vision detection system 20 establishes an association relationship between the first inspection result of the battery and the marking information of the battery, and subsequent the first inspection result of the battery can be quickly located through the marking information of the battery. Since the vision detection system 20 completes the battery image acquisition, battery marking identification, battery appearance inspection, and association of battery marking and the first inspection result during the transportation of the battery by the logistics line 11, a series of appearance inspection actions on the battery and the transportation action of the battery are carried out in parallel, that is, the transportation of the battery by the logistics line 11 is continuous, and a series of appearance inspection actions on the battery 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 realized without affecting the battery transportation rhythm, meeting the high-rhythm production requirements of the production line.

[0115] In a specific embodiment, the vision detection system 20 is correspondingly arranged at the detection station of the logistics line 11. 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 respectively located at the feeding position and the discharging position of the detection station. It should be noted that the vision detection 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 to associate with the first inspection result of the battery.

[0116] Of course, in other specific embodiments, a battery identification device can also be provided only at the feeding position or the discharging position of the detection station, which is not limited here.

[0117] In a specific embodiment, the image acquisition device and at least one battery identification device are located before the sorting point 12. Since the image acquisition device and at least one battery identification device are located before the sorting point 12, the appearance inspection of the battery by the vision detection system 20 is before the sorting of the battery by the sorting system 10, so that the sorting system 10 can sort out the batteries with appearance defects and those without appearance defects, ensuring the consistency of the batteries.

[0118] In a specific embodiment, the vision detection system 20 is specifically used to perform defect detection on the battery using the battery image to obtain a defect detection result, and obtain the first inspection result of the battery based on the defect detection result. The first inspection result indicates whether the battery is qualified. That is to say, it is determined whether the battery is qualified through the defect detection result of the battery image of the battery.

[0119] In a specific embodiment, the first detection result of the battery indicates that the battery is qualified or unqualified. When the defect detection result of the battery indicates that there are candidate defects on the battery surface, the first detection result of the battery is that the battery is unqualified; while when the defect detection result of the battery indicates that there are no candidate defects on the battery surface, the first detection result of the battery is that the battery is qualified.

[0120] In a specific embodiment, the battery image includes sub-images of each surface of the battery to be detected, the defect detection result includes sub-detection results corresponding to each surface to be detected, and the first detection result of the battery is that the battery is qualified or unqualified. When the sub-detection result of any surface of the battery to be detected indicates that there are candidate defects on the surface to be detected, the first detection result of the battery is that the battery is unqualified; while when the sub-detection results of all surfaces of the battery to be detected indicate that there are no candidate defects on the surface to be detected, the first detection result of the battery is that the battery is qualified.

[0121] In an embodiment, the vision detection system 20 is further configured to send a recheck request message about the battery to the recheck cloud system 30 when the first detection result of the battery meets the recheck condition. The recheck request message includes the marking information of the battery, the battery appearance information, and the first detection result. The battery appearance information includes at least one of the battery image and the position information of the candidate defect area of the battery. The recheck cloud system 30 is configured to receive the recheck request message about the battery sent by the vision detection system 20, generate a recheck task for the battery and assign the recheck task to the recheck edge system 50, and receive the second detection result of the battery fed back after the recheck edge system 50 executes the recheck task, and update the second detection result of the battery as the latest appearance detection result of the battery.

[0122] That is to say, when the first detection result of the battery detected by the vision detection system 20 meets the recheck condition, the vision detection system 20 sends a recheck request message about the battery to the recheck cloud system 30, so that after the recheck cloud system 30 receives the recheck request message about the battery sent by the vision detection system 20, it assigns a recheck task to the recheck edge system 50, so that the recheck edge system 50 performs an appearance recheck on the battery.

[0123] It should be noted that the first detection result of the battery is that the battery is qualified or unqualified, the recheck condition is that the first detection result is that the battery is in the target appearance state, and the target appearance state is the qualified state. Therefore, the battery that meets the recheck condition is the battery with the first detection result being qualified. When performing an appearance recheck on a qualified battery with the first detection result being qualified, the recheck request message does not include the position information of the candidate defect area of the battery.

[0124] Among them, the battery image may include sub-images of each surface of the battery to be detected. When sending a re-judgment request message about the battery including the battery image to the re-judgment cloud system 30, it may be to send sub-images of all surfaces of the battery to be detected to the re-judgment cloud system 30.

[0125] In addition, it should be noted that the first detection result of the battery is that the battery is qualified or unqualified, and the re-judgment condition is that the first detection result is that the battery is in the target appearance state, and the target appearance state is the unqualified state. Therefore, the battery that meets the re-judgment condition is the battery with an unqualified first detection result. When performing an appearance re-judgment on the unqualified battery with an unqualified first detection result, the re-judgment request message includes the battery image, and the battery image includes sub-images of each surface of the battery to be detected, it may be to send sub-images of the surface to be detected with candidate defects of the battery to the re-judgment cloud system 30.

[0126] In an embodiment, the re-judgment cloud system 30 is further configured to perform the step of updating the second detection result of the battery as the latest appearance detection result of the battery when it is determined that the current preset conditions are met, where the preset conditions include 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.

[0127] The preset condition includes that the second detection result of the battery is inconsistent with the first detection result of the battery; that is, when the second detection result of the battery is inconsistent with the first detection result of the battery, the second detection result of the battery is updated as the latest appearance detection result of the battery. The inconsistency between the second detection result of the battery and the first detection result of the battery indicates that the first detection result of the battery is incorrect. Then, the latest appearance detection result of the battery - the first detection result of the battery is incorrect, and the latest appearance detection result of the battery - the first detection result of the battery cannot truly reflect the appearance of the battery. At this time, updating the second detection result of the battery as the latest appearance detection result of the battery and updating the latest appearance detection result of the battery to the second detection result of the battery can make the latest appearance detection result of the battery accurately reflect the appearance of the battery. If the second detection result of the battery is updated as the latest appearance detection 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 detection result of the battery that reflects the true appearance of the battery. If the second detection result of the battery is updated as the latest appearance detection result of the battery after the logistics line 11 transports the battery to the sorting point 12, since the latest appearance detection result of the battery is updated, it is convenient for the user to query and determine the true appearance of the battery later and is convenient for traceability.

[0128] The preset conditions include that the sorting system 10 is not currently sorting the battery. That is, when the sorting system 10 is not currently sorting the battery, the second detection result of the battery is updated as the latest appearance detection result of the battery. Since the sorting system 10 sorts the battery based on the latest appearance detection result of the battery, whether to update the latest appearance detection result of the battery affects the sorting of the battery by the sorting system 10. If the sorting system 10 has currently sorted the battery, then whether to update the latest appearance detection result of the battery no longer affects the sorting of the battery by the sorting system 10, and there is no need to update the latest appearance detection result of the battery. If the sorting system 10 is not currently sorting the battery, then whether to update the latest appearance detection result of the battery still affects the sorting of the battery by the sorting system 10, and it is necessary to update the latest appearance detection result of the battery.

[0129] The preset conditions include that 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. That is, when 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, the second detection result of the battery is updated as the latest appearance detection result of the battery. The inconsistency between the second detection result of the battery and the first detection result of the battery indicates that the first detection result of the battery is incorrect. Then, the latest appearance detection result of the battery - the first detection result of the battery is incorrect, and the latest appearance detection result of the battery - the first detection 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 detection result of the battery, whether to update the latest appearance detection result of the battery affects the sorting of the battery by the sorting system 10. And if the sorting system 10 is not currently sorting the battery, then whether to update the latest appearance detection result of the battery will affect the sorting of the battery by the sorting system 10. At this time, the latest appearance detection result of the battery will be updated so that the latest appearance detection result of the battery can accurately reflect the appearance of the battery. Then, when the sorting system 10 sorts the battery, it can sort the battery accurately based on the latest appearance detection result that reflects the true appearance of the battery.

[0130] In a specific embodiment, the preset conditions include that the sorting system 10 is not currently sorting the battery. The battery appearance detection system 100 further includes a production execution system 40, and the production execution system 40 is used to record the sorting status of the battery transported on the logistics line 11. The rejudgment cloud system 30 is further used to query the production execution system 40 about the current sorting status of the battery to determine whether the sorting system 10 is currently sorting the battery.

[0131] After the sorting system 10 sorts the batteries based on the latest appearance detection results of the batteries, it feeds back the sorting status of the batteries to the production execution system 40, so that the production execution system 40 can learn and record the sorting status of the batteries in a timely manner, enabling the subsequent rejudgment cloud system 30 to quickly and accurately respond to the query of the sorting status of the batteries. Since the rejudgment cloud system 30 updates the second detection result of the battery as the latest appearance detection result of the battery after determining that the sorting system 10 is not currently sorting the battery, the rejudgment cloud system 30 will also determine whether the sorting system 10 is currently sorting the battery through the production execution system 40 to determine whether it is necessary to update the latest appearance detection result of the battery with the second detection result of the battery.

[0132] In a specific embodiment, the rejudgment cloud system 30 consists of a server, picture scheduling software, algorithms, etc.

[0133] In a specific embodiment, the rejudgment edge system 50 consists of rejudgment software, an industrial computer, a display screen, etc.

[0134] In a specific embodiment, the rejudgment request information includes battery appearance information, and the battery appearance information includes the battery image of the battery and the position information of the candidate defect area of the battery in the battery image; the rejudgment cloud system 30 is also used to mark the candidate defect area of the battery image based on the position information of the candidate defect area, and when allocating the rejudgment task to the rejudgment edge system 50, send the marked battery image to the rejudgment edge system 50.

[0135] By marking the candidate defect area of the battery image, the candidate defect area in the marked battery image is highlighted, so that when the rejudgment edge system 50 performs appearance rejudgment based on the marked battery image, it can focus on the candidate defect area in the battery image faster and more accurately for appearance rejudgment, realizing efficient and accurate appearance rejudgment of the battery.

[0136] In a specific embodiment, the rejudgment edge system 50 includes a number of rejudgment edge devices, and the rejudgment cloud system 30 is also used to allocate the rejudgment task of the battery to one of the rejudgment edge devices based on a scheduling algorithm. The scheduling algorithm is used to allocate the rejudgment task of the battery to allocate the rejudgment task of the battery to an idle or less rejudgment task rejudgment edge device, so as to be able to perform appearance rejudgment on the battery in a timely manner.

[0137] In other specific embodiments, the rejudgment cloud system 30 can also randomly send the rejudgment task of the battery to a rejudgment edge device, which is not limited here.

[0138] In a specific embodiment, the rejudgment edge system 50 is used to display the battery image of the battery to the rejudgment personnel and generate a second detection result of the battery in response to the rejudgment operation of the rejudgment personnel. The battery image of the battery is visually presented to the user in real time through the rejudgment edge system 50, and the second detection result of the battery is obtained through the rejudgment operation of the rejudgment personnel; that is, the rejudgment edge system 50 realizes efficient and accurate appearance rejudgment of the battery through battery image display and interactive operation response.

[0139] In one embodiment, the battery appearance detection system 100 further includes a third battery identification device 13 disposed at the sorting point 12, and the third battery identification device 13 is used to identify the marking information of the battery passing through the sorting point 12; wherein, the sorting system 10 is further used to query the latest appearance detection result of the battery currently located at the sorting point 12 by using the marking information identified by the third battery identification device 13.

[0140] When the battery is transported to the sorting point 12 by the logistics line 11, the third battery identification device 13 disposed at the sorting point 12 will perform marking identification on the battery to identify the marking information of the battery; before the sorting system 10 sorts the battery, it will query the latest appearance detection result of the battery currently located at the sorting point 12 based on the marking information of the battery identified by the third battery identification device 13 disposed at the sorting point 12.

[0141] 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 disposed at the sorting point 12 will perform marking identification on the battery to identify the marking information of the battery; before the sorting system 10 sorts the battery, it will generate a query mark based on the marking information of the battery identified by the third battery identification device 13 disposed at the sorting point 12 and send it to the production execution system 40; the production execution system 40 can query the latest appearance detection result of the battery according to the marking information of the battery and feedback it to the sorting system 10, so that the sorting system 10 can accurately sort the battery based on the latest appearance detection result of the battery.

[0142] In one embodiment, the battery appearance detection system 100 further includes a third battery identification device 13 disposed at the sorting point 12. The third battery identification device 13 is used to identify the marking information of the battery passing through the sorting point 12. Among them, the battery appearance detection system 100 further includes a production execution system 40. The sorting system 10 is further configured to, in response to identifying the marking information of the battery passing through the sorting point 12 by using the third battery identification device 13, sort the battery passing through the sorting point 12 and feed back a battery sorted notification to the production execution system 40. The battery sorted notification includes the marking information identified by the third battery identification device 13 and is used to notify the production execution system 40 to record the sorting status of the battery corresponding to the marking information as sorted. That is to say, after the sorting system 10 sorts the battery based on the latest appearance detection result of the battery, it sends a battery sorted notification including the marking information of the battery to the production execution system 40. After the production execution system 40 receives the battery sorted notification, it marks the marking information as sorted to record the sorting status of the battery corresponding to the marking information as sorted.

[0143] 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.

[0144] In one embodiment, the appearance detection result of the battery is that the battery is qualified or unqualified. The sorting system 10 executes sorting the battery based on the latest appearance detection result of the battery, specifically: in response to the latest appearance detection result of the battery being that the battery is qualified, controlling the logistics line 11 to transport the battery to the qualified battery processing area 14; in response to the latest appearance detection result of the battery being that the battery is unqualified, controlling the logistics line 11 to transport the battery to the unqualified battery processing area 15.

[0145] That is to say, when the latest appearance detection result of the battery is that 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 to perform corresponding processing on the qualified battery in the qualified battery processing area 14; when the latest appearance detection result of the battery is that 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 to perform corresponding processing on the unqualified battery in the unqualified battery processing area 15.

[0146] In a specific embodiment, the qualified battery processing area 14 is provided with qualified battery processing equipment. In the qualified battery processing area 14, the qualified battery processing equipment will be used to process the qualified battery. For example, the qualified battery processing equipment is a packing machine. In the qualified battery processing area 14, the packing machine will be used to pack the qualified battery.

[0147] In a specific embodiment, there are several visual inspection personnel in the unqualified battery processing area 15. In the unqualified battery processing area 15, the several visual inspection personnel will re-judge or process the unqualified battery.

[0148] In one embodiment, the appearance inspection result of the battery is that 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. The logistics line 11 includes a first logistics branch line 111 and a second logistics branch line 112 located after the sorting point 12.
