[0002] At present, some electronic devices and other items need to be tested for insulation and withstand voltage during the manufacturing process to improve the safety of the items. Take the battery cover as an example. Before the battery cover is processed into a package, it is equivalent to a capacitor. If there are metal chips, dust, welding convexity, burrs, etc. between the conductive column core and the inner or outer surface of the cover, the insulation distance will be reduced.

[0003] Therefore, it is necessary to undergo a high potential test (High Potential (or Voltage) Test, Hi-Pot) during the processing of the battery cover, that is, to use a circuit to connect the measuring instrument to the battery cover to be tested for testing, and then obtain the electrical performance test results of the battery cover.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or relative positional relationships shown in the drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on this application. Unless otherwise specified, the above-mentioned directional description can be flexibly set in the process of actual application under the condition of satisfying the relative positional relationship shown in the drawings.

[0052] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0053] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0054] In the present application, the terms "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, article or device including the element.

[0055] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0056] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0057] At present, some electronic devices and other items need to undergo insulation and withstand voltage electrical performance testing during the processing and manufacturing process to improve the safety of the items.

[0058] It should be understood that for ease of description, the present embodiment takes the battery cover as an example of the object to be tested, but this description does not constitute a limitation. In practical applications, the type of object to be tested can be determined according to needs. For example, the method provided in the present embodiment can be applied to battery covers, power battery supporting trays, and other consumer electronic structural parts.

[0059] The battery cover needs to be tested for electrical performance during its processing. Before the battery cover is processed into a package, it is equivalent to a capacitor. Metal scraps, dust, welding convexity, burrs, etc. between the conductive column core and the inner or outer surface of the cover will cause the insulation distance to become lower. Therefore, it is necessary to perform a high potential test (Hi-Pot) during the processing of the battery cover, that is, to connect the measuring instrument to the tested battery cover using a line for testing, and then obtain the electrical performance test results of the battery cover.

[0060] In related technologies, such as Figure 1 and Figure 2 As shown, when performing a high potential test, a detection circuit is required to connect the high voltage test device 10 with the battery cover 20 to detect the electrical performance of the battery cover under test. The test principle can be as follows Figure 3 As shown, Figure 3 The Inside part represents the high-voltage detection equipment and detection circuit, and the Outside part represents the battery cover under test.

[0061] like Figure 3 As shown, the test process is divided into three stages. By continuously monitoring the voltage changes in the three processes, it is determined whether the battery cover is normal: Charging stage (Step 1): Pulse charging is performed on the battery cover under test, and the charging voltage changes are detected after each pulse. Holding stage (Step 2): There is no abnormality in the charging stage, and the voltage is maintained for a certain period of time after reaching the test voltage. Discharging stage (Step 3): Check whether the discharge process is smooth.

[0062] The voltage changes are obtained in real time during the detection process. It can be seen that the voltage waveform example with an OK detection result can reach the set voltage in Step 1, and the voltage is maintained for a long time in Step 2, and it drops to 0 after a period of time in Step 1. However, the voltage waveform example #1 with an NG detection result did not reach the set voltage in Step 1, and the voltage waveform example #2 with an NG detection result had a very short voltage maintenance time in Step 2.

[0063] At present, when testing the electrical performance of battery cover, the control program is generally set to carry out assembly line operation, such as Figure 4 As shown, the procedure for inspecting a battery cover includes the following steps: the materials are prepared in place, and a high-voltage test is performed. If the high-voltage test fails, the materials are discarded. If the high-voltage test passes, a code is scanned and a station is used to compare the information of the results returned by the high-voltage test device. If the code is scanned and the station fails, the materials are discarded. If the code is scanned and the station passes, the materials flow into the next process.

[0064] However, if the circuit has poor contact with the battery cover under test or the measuring instrument fails, in this case, the electrical performance of the battery cover under test is qualified, but the obtained electrical performance test results indicate that the electrical performance of the battery cover under test is indeed unqualified, that is, the measuring instrument misjudged the electrical performance of the battery cover under test.

[0065] Based on this, the present application proposes a high-voltage detection method for an object, including: testing a high-voltage detection device to determine the high-voltage detection result of the high-voltage detection device; when the high-voltage detection result is qualified, using the high-voltage detection device to perform high-voltage detection on the object to be tested to obtain a performance detection result of the object to be tested, and the performance detection result is used to indicate whether the electrical performance of the object to be tested is qualified. Therefore, before using the high-voltage detection device to detect the electrical performance of the object to be tested, the high-voltage detection result of the high-voltage detection device is first determined. When the high-voltage detection result of the high-voltage detection device is qualified, the electrical performance of the object to be tested is detected by the high-voltage detection device again, thereby avoiding misjudgment of the electrical performance of the object to be tested due to the high-voltage detection device, and improving the accuracy of the electrical performance detection of the object to be tested.

[0066] The high-voltage detection method for an object provided in the embodiment of the present application can be applied to Figure 5 High voltage detection system for the items shown. Figure 5 As shown, the high-voltage detection system for an article includes: a control device (not shown in the figure), a high-voltage testing device 10 and an article carrying device 30 .

[0067] The high-voltage detection device 10 is used to detect the electrical properties of the object to be detected, and the object carrying device 30 is used to carry the object to be detected (such as the battery cover plate 20 to be detected). When the electrical properties of the battery cover plate 20 to be detected are detected by the high-voltage detection device 10, the control device controls the object carrying device 30 to be lifted to the set position, and then controls the probe to be lowered to contact the battery cover plate 20 to be detected. When the probe contacts the battery cover plate 20 to be detected, it indicates that the positive and negative electrodes of the high-voltage detection device are connected to the battery cover plate to be detected. The control device can be a programmable logic controller (PLC).

[0068] Figure 6 It shows the signal principle diagram of the high voltage tester during testing. The first terminal of the high voltage tester is used to output the high voltage result OK, and the second terminal of the high voltage tester is used to output the high voltage result NG. Among them, the high voltage result OK means that the electrical performance of the tested battery cover is qualified, and the high voltage result NG means that the electrical performance of the tested battery cover is unqualified.

[0069] The third terminal of the high-voltage tester is used to connect to the trigger detection interface of the control device, and the fourth terminal of the high-voltage tester is used to connect to the reset signal interface of the control device. In the actual detection process, the control device sends a detection trigger signal to the high-voltage tester. After the third terminal of the high-voltage tester receives the detection trigger signal, it controls the high-voltage tester to start working. After the high-voltage detection of the battery cover under test is completed, the control device sends a reset signal to the high-voltage tester. After the fourth terminal of the high-voltage tester receives the reset signal, it resets.

[0070] In some embodiments, the high voltage detection device includes: a conduction test module and a short circuit detection module, the conduction test module is used to determine the electrical connection detection result of the high voltage test device, and the short circuit detection module is used to determine the equipment self-test result.

[0071] like Figure 7 and Figure 8 As shown, this application Figure 5 and Figure 6 The structural schematic diagram of the electrical connection between the high-voltage tester and the battery cover under test and the signal schematic diagram of the high-voltage tester are optimized, and a relay module 40 is added. Figure 7 A schematic diagram showing the electrical connection between the high-voltage test device and the battery cover under test. The high-voltage test device, the battery under test and the relay module are connected through a detection circuit. The figure includes two battery covers. Taking one battery cover as an example, there are 4 contact points on one battery cover, and each contact point is connected to the detection circuit through a probe. When conducting a continuity test, every two probes correspond to one relay.

[0072] Figure 8 The circuit schematic diagram of the high-voltage test device for testing the battery cover includes: a first power source E1, a first cover 1, a second cover 2, a high-voltage tester, a first relay K1, a second relay K2, a third relay K3, a fourth relay K4, a fifth relay K5, a sixth relay K6, a first diode D1, a second diode D2, a third diode D3, a fourth diode D4, a fifth diode D5, and a sixth diode D6.

[0073] The first diode D1 is connected to the third end of the first relay K1, the second diode D2 is connected to the third end of the second relay K2, the third diode D3 is connected to the third end of the second relay K2, and the fourth diode D4 is connected to the third end of the second relay K2, for controlling the direction of the current during the conduction test. The fifth diode D5 and the sixth diode D6 are connected to the positive and negative electrodes of the second power supply (not shown in the figure), and play a role in insulating the second power supply from the first power supply E1.

[0074] Among them, the first relay K1, the second relay K2, the third relay K3 and the fourth relay K4 are used to determine the electrical connection detection result, and the fifth relay K5 and the sixth relay K6 are used to determine the equipment self-test result. Taking the first cover plate 1 as an example, the first cover plate 1 has four probes. When determining the electrical connection detection result, the first cover plate 1 corresponds to two relays, namely the first relay K1 and the fourth relay K4. When determining the equipment self-test result, the first cover plate 1 corresponds to the fifth relay K5.

[0075] In some embodiments, when the first relay K1 corresponds to the first probe and the second probe, when determining the electrical connection detection result between the high-voltage test device and the battery cover, the current starts from the positive pole of the first power source E1, passes through the first diode D1, flows into the third end of the first relay K1, and flows out from the fourth end of the first relay K1. When the current flows through the first relay K1, the coil in the first relay K1 forms a magnetic field to control the switch in the first relay K1 to close. The first end of the first relay K1 is connected to the first power source E1, and the second end of the first relay K1 is connected to the PLC. After controlling the switch in the first relay K1 to close, the PLC can detect the voltage signal corresponding to the first power source E1, indicating that the electrical connection detection result is qualified. If there is no current in the first relay K1 due to problems such as a broken circuit or poor contact in the detection line, the PLC detects a 0V voltage signal, indicating that the electrical connection detection result is unqualified.

[0076] When determining the electrical connection detection result between the high-voltage test device and the battery cover, the second relay K2, the third relay K3 and the fourth relay K4 can refer to the description of the first relay K1, which will not be repeated here.

[0077] In some embodiments, the fifth relay K5 corresponds to the first probe and the second probe. When determining the equipment self-test result of the high-voltage testing device, the current starts from the positive pole of the second power supply (not shown in the figure), flows into the first end of the fifth relay K5, and flows out from the second end of the fifth relay K5. The third end of the fifth relay K5 is connected to the first power supply E1, and the fourth end of the fifth relay K5 is connected to the PLC. The PLC controls the switch in the fifth relay K5 to close, and the fifth relay K5 is turned on. At this time, the high-voltage detector is short-circuited, and it is determined whether the high-voltage detector can detect the first cover plate 1. If the first cover plate 1 can be detected, it means that the equipment self-test result is unqualified. If the first cover plate 1 cannot be detected, it means that the equipment self-test result is qualified.

[0078] When determining the self-test result of the high-voltage test device, the sixth relay K6 can refer to the description of the fifth relay K5, which will not be repeated here. Figure 6 The description in will not be repeated here.

[0079] It should be noted that the high-voltage detection method of the article of the present application is applicable to the control device of the high-voltage detection system of the above-mentioned article. Among them, the control device can be a personal computer (PC), a laptop computer, a mobile device, a tablet computer, a laptop computer and other electronic devices, and the embodiments of the present application do not limit the specific form of the electronic device. Alternatively, the control device can also be a separate server, or a server cluster composed of multiple servers. In some implementations, the server cluster can be a distributed cluster server. The embodiments of the present application do not impose any restrictions on this.

[0080] like Fig. 9 As shown, the high-voltage detection method of an article provided in an embodiment of the present application includes:

[0081] S901. Detect the high-voltage detection device to determine the high-voltage detection result of the high-voltage detection device.

[0082] It should be noted that the accuracy of high-voltage detection devices, as key tools for detecting the electrical performance of electrical equipment or electronic equipment, is of vital importance. By testing high-voltage detection devices, the accuracy and reliability of their measurement results can be ensured, thereby avoiding misjudgment and improving the accuracy of the test results.

[0083] In some embodiments, the high voltage detection device may be tested from aspects such as the reliability of the high voltage detection device and the accuracy of the test results obtained by using the high voltage detection device. The specific process may be to repeatedly test the high voltage detection device multiple times, and determine whether the high voltage detection device of the high voltage detection device is qualified through the multiple test results. It is also possible to increase the process of testing the standardized high voltage detection device on the basis of the above-mentioned multiple repeated tests, and compare the multiple test results to determine whether the high voltage detection device of the high voltage detection device is qualified.

[0084] S902: When the high-voltage test result is qualified, a high-voltage test is performed on the object to be tested by using a high-voltage test device to obtain a performance test result of the object to be tested.

[0085] The performance test result is used to indicate whether the electrical performance of the item to be tested is qualified. The item to be tested is any of the following: battery cover, electronic equipment, power equipment, battery equipment, or energy storage equipment.

[0086] Optionally, high-voltage detection of the object to be tested using a high-voltage detection device is mainly a conventional high-voltage performance test. The high-voltage detection device continuously outputs a set constant voltage current to the battery cover under test within a set time. At this time, when the current reaches the battery cover under test (non-abnormal cover) through the detection circuit, the current is disconnected, and the positive and negative charges converge on the cover under test to form an electric potential difference. At this time, the cover is similar to a capacitor.

[0087] Exemplarily, within a set time (millisecond level), the potential difference on the battery cover under test reaches the set voltage (charging) issued by the high-voltage detection device. At this time, there is a high potential difference on the battery cover under test. After maintaining for a period of time, the reverse reflux is gradually performed to reduce the voltage (maintain and discharge). During the charging, maintaining and discharging processes of the battery cover under test, the duration of each process is detected. If the voltage reaches the set value within the target time, the high-voltage performance of the battery cover under test is determined to be qualified. On the contrary, if the voltage does not reach the set value during the charging process, the time to reach the set value exceeds the specified time, the voltage duration during the maintaining process does not reach the set time, and the voltage reduction rate during the discharging process exceeds the specified value, the high-voltage performance of the battery cover under test is determined to be unqualified.

[0088] It should be noted that electrical performance refers to performance indicators such as rated voltage, current, active power, reactive power, resistance, capacitance, inductance, and conductivity of electrical components. Usually, the voltage resistance and insulation performance of electrical components are tested using insulation strength testing equipment. This application uses a high-voltage testing device to detect the electrical properties of the battery cover under test, which is actually to detect the high-voltage performance of the battery cover under test, that is, the insulation performance of the battery cover.

[0089] Furthermore, when the performance test results indicate that the electrical performance of the item to be tested is unqualified, the item is determined to be a scrap item; when the performance test results indicate that the electrical performance of the item to be tested is qualified, the item is determined to be a normal item. Since the detection of the electrical performance of the item to be tested is an assembly line operation, when the electrical performance of the item to be tested is qualified, the item to be tested enters the code scanning station, and mainly verifies the information based on the results returned by the high-voltage testing device. For the items to be tested that fail to pass the code scanning station, material waste is executed, and for the items to be tested that pass the code scanning station, they flow into the program for the next process.

[0090] Based on S901-S902, it can be seen that the high-voltage detection method for an object provided in the embodiment of the present application first determines the high-voltage detection result of the high-voltage detection device before using the high-voltage detection device to detect the electrical properties of the object to be detected. If the high-voltage detection result of the high-voltage detection device is qualified, the electrical properties of the object to be detected are detected by the high-voltage detection device, thereby avoiding misjudgment of the electrical properties of the object to be detected due to the high-voltage detection device, and improving the accuracy of the electrical properties detection of the object to be detected.

[0091] In some embodiments, when a high-voltage detection device is actually used to perform high-voltage detection on an object to be tested, the high-voltage detection device is used very frequently, and the circuit and the high-voltage detection equipment are under heavy load, which may lead to failure. Therefore, before using the high-voltage detection device to perform high-voltage detection on the object to be tested, the circuit and the high-voltage detection equipment may be tested to test whether the high-voltage detection device is reliable, so that the electrical performance test of the object to be tested can be performed when the high-voltage detection device is qualified, so as to achieve the purpose of improving the accuracy of the electrical performance test results of the object to be tested.

[0092] Therefore, as a feasible implementation method, the above-mentioned high-voltage detection result includes an electrical connection detection result and / or a device self-test result. That is, the high-voltage detection result includes an electrical connection detection result, or a device self-test result, or an electrical connection detection result and a device self-test result.

[0093] Among them, the electrical connection detection result is used to indicate whether there is an abnormality in the electrical connection between the high-voltage detection device and the object to be tested, and the equipment self-test result is used to indicate whether there is an abnormality in the high-voltage detection device.

[0094] In some embodiments, when the test result includes an electrical connection test result, determining the high voltage test result of the high voltage test device includes: when the electrical connection test result is that there is no abnormality in the electrical connection between the high voltage test device and the object to be tested, determining that the high voltage test result is qualified. When the electrical connection test result is that there is an abnormality in the electrical connection between the high voltage test device and the object to be tested, determining that the high voltage test result is unqualified.

[0095] In other embodiments, when the detection result includes a device self-test result, determining the high voltage detection result of the high voltage detection device includes: when the device self-test result is that there is no abnormality in the high voltage detection device, determining that the high voltage detection result is qualified. When the device self-test result is that there is an abnormality in the high voltage detection device, determining that the high voltage detection result is unqualified.

[0096] In other embodiments, when the test results include an electrical connection test result and a device self-test result, determining the high voltage test result of the high voltage test device includes: when the electrical connection test result is that there is no abnormality in the electrical connection between the high voltage test device and the object to be tested, and the device self-test result is that there is no abnormality in the high voltage test device, determining that the high voltage test result is qualified. When the electrical connection test result is that there is an abnormality in the electrical connection between the high voltage test device and the object to be tested, or the device self-test result is that there is an abnormality in the high voltage test device, determining that both high voltage test results are unqualified.

[0097] It should be noted that when the high-voltage detection device performs self-test, it is also necessary to use the test line. If the self-test result of the high-voltage detection device fails, it may be due to a fault in the test line. Therefore, when the test results include the electrical connection test results and the equipment self-test results, the electrical connection test results are usually determined first, and the equipment self-test results are determined when the electrical connection test results are qualified. If the electrical connection test results are unqualified, then there is no need to perform self-test of the high-voltage detection device, thereby speeding up the efficiency of determining the high-voltage test results.

[0098] Furthermore, when the high voltage detection result is unqualified, the high voltage detection device issues an alarm message. After receiving the alarm message, the user checks the reason why the high voltage detection device issues an alarm and replaces or repairs the components in the high voltage detection device that may have a fault.

[0099] In some embodiments, since the high voltage detection device is connected to the battery cover plate under test through a detection circuit, the quality of the detection circuit and the contact between the probe and the object under test directly affect the electrical connection between the high voltage detection device and the object under test. Fig. 9 ,like Fig.10 As shown, the above S901 includes the following steps:

[0100] S1001, controlling the probe to move toward the object to be tested.

[0101] Wherein, the probe is electrically connected to the high voltage detection device.

[0102] The probe moves toward the object to be tested, and when the probe moves a certain distance, the probe and the object to be tested will come into contact. Since the probe is electrically connected to the high-voltage detection device, when the circuit is normal, there will also be an electrical connection between the high-voltage detection device and the battery cover.

[0103] As a feasible implementation method, after the control device controls the article carrying device to move to a set position, the control device controls the probe to descend to a set height.

[0104] For example, Figure 7 Taking a battery cover as an example, the control probe is pressed down to contact the battery cover under test. In this way, when the circuit is normal, the high-voltage detection device and the battery cover form a detection loop.

[0105] In some embodiments, the high voltage detection device provides a 24V low voltage power supply, the first probe and the second probe contact the battery cover, the current flows from the first probe into the battery cover, and flows out from the second probe after passing through the battery cover.

[0106] In other embodiments, the high-voltage detection device provides a 24V low-voltage power supply, and the third probe and the fourth probe descend to contact the pole on the battery cover, and the current flows from the third probe into the pole on the battery cover, and flows out from the fourth probe after passing through the battery cover.

[0107] S1002: Determine the signal detection result between the object to be tested and the high voltage detection device.

[0108] The signal detection result is used to indicate whether there is a signal corresponding to the first power supply between the object to be tested and the high-voltage detection device.

[0109] In some embodiments, when the battery cover and the high-voltage detection device form a detection loop, the PLC is used to detect whether there is a signal corresponding to the first power supply on the detection loop between the battery cover and the high-voltage detection device to determine the on / off status of the detection loop.

[0110] Taking the first power supply as a 24V low-voltage power supply as an example, the signal corresponding to the first power supply is a 24V voltage signal, such as Fig.11 As shown in the figure, if there is no abnormality in the detection circuit, the PLC will detect a 24V voltage signal. Fig.11 As shown, there is an abnormality in the probe, resulting in no connection between the probe and the battery cover, that is, there is an abnormality in the detection circuit, and the PLC will detect a 0V voltage signal.

[0111] Therefore, the on-off status of the detection circuit can be determined by detecting whether a signal corresponding to the first power supply exists in the detection circuit between the battery cover and the high-voltage detection device.

[0112] S1003. Determine an electrical connection detection result based on the signal detection result.

[0113] It can be understood that, when the test result is that there is a signal corresponding to the first power supply between the object to be tested and the high-voltage testing device, it indicates that there is current flowing between the object to be tested and the high-voltage testing device, and therefore it can be determined that the electrical connection test result of the high-voltage testing device is qualified. When the test result is that there is no signal corresponding to the first power supply between the object to be tested and the high-voltage testing device, it indicates that there is no current flowing between the object to be tested and the high-voltage testing device, and therefore it can be determined that the electrical connection test result of the high-voltage testing device is unqualified.

[0114] Furthermore, since the detection circuit is blocked, it means that there is a circuit break or the probe is not in contact with the battery cover, there will be no current in the detection circuit, and the PLC will not detect the signal corresponding to the first power supply. Therefore, if the electrical connection test result is unqualified, the equipment shutdown alarm can be triggered, so that the user can detect the cause of the fault after receiving the alarm information to eliminate the abnormal problem of the electrical connection between the object to be tested and the high-voltage detection device.

[0115] Based on S1001-S1003, it can be seen that the electrical connection detection result between the high-voltage detection device and the object to be tested is determined according to the signal detection result between the object to be tested and the high-voltage detection device. When the electrical connection detection result is qualified, the electrical properties of the object to be tested are detected by the high-voltage detection device. In this way, the electrical properties of the object to be tested are detected when the high-voltage detection device and the object to be tested are effectively connected, thereby avoiding misjudgment of the electrical properties of the object to be tested and improving the accuracy of electrical property detection of the object to be tested.

[0116] In some embodiments, since the performance of the high-voltage detection device itself will also affect the electrical performance test results of the battery cover under test, the high-voltage detection device itself can also be checked after the electrical connection test between the high-voltage detection device and the battery cover under test. Fig. 9 and Fig.10 ,like Fig.12 As shown, the above step S901 also includes the following steps:

[0117] S1201, controlling the object to be tested to be connected to the high-voltage detection device, and controlling the first circuit to be turned on.

[0118] Wherein, the first circuit is used to connect the positive and negative electrodes of the high voltage detection device.

[0119] For example, Figure 7 Taking a battery cover as an example, the control probe is pressed down to contact the battery cover to be tested, so that the high-voltage detection device and the battery cover form a detection circuit. Among them, the first probe and the second probe contact the battery cover, and the third probe and the fourth probe are lowered to contact the pole on the battery cover. The first circuit contacts these four probes, and two of the four probes are randomly selected to be connected with the first circuit, so that the positive and negative poles of the high-voltage detection device are short-circuited, and the current flowing out of the positive pole of the high-voltage detection device directly returns to the negative pole of the high-voltage detection device through the first circuit without passing through the battery cover.

[0120] S1202: Determine whether the high-voltage detection device can detect the object to be detected, and obtain a recognition result of the high-voltage detection device.

[0121] Optionally, the high-voltage detection device continuously outputs a set constant voltage current within a set time. The high-voltage detection device detects the current in the loop formed by the object to be tested and the high-voltage detection device, and determines whether the object to be tested is detected based on the magnitude of the current in the loop. When the current is relatively small, it indicates that the object to be tested is detected. When the current is very large and exceeds the set value, it indicates that the object to be tested cannot be detected.

[0122] Exemplarily, the high-voltage detection device continuously outputs a constant voltage current of 1200V within 250 milliseconds, and the high-voltage detection device determines whether the battery cover under test can be detected.

[0123] S1203. Determine the equipment self-test result according to the identification result of the high-voltage detection device.

[0124] In some embodiments, when the identification result indicates that the object to be tested can be detected, it indicates that the high-voltage detection device is invalid, and therefore the equipment self-test result of the high-voltage detection device can be determined to be unqualified. When the identification result indicates that the object to be tested cannot be detected, it indicates that the high-voltage detection device is valid, and therefore the equipment self-test result of the high-voltage detection device can be determined to be qualified.

[0125] It should be noted that if the equipment self-test result is unqualified, it means that the high-voltage detection device has failed, but there is still a possibility that the first line is abnormal and the high-voltage detection device is not short-circuited. Therefore, if the equipment self-test result is unqualified, it is necessary to further determine the cause of the failure of the high-voltage detection device.

[0126] Based on S1201-S1203, it can be seen that if the high-voltage detection device is effective, after the high-voltage detection device is short-circuited, the current flowing out of the positive electrode of the high-voltage detection device directly returns to the negative electrode of the high-voltage detection device through the first line without passing through the battery cover. There is a very large current in the loop, and the high-voltage detection device cannot identify the battery cover under test. By determining the recognition result of the high-voltage detection device and performing a self-test on the high-voltage detection device according to the recognition result of the high-voltage detection device, the high-voltage detection device is effective when detecting the electrical properties of the item to be tested, avoiding misjudgment of the electrical properties of the item to be tested, and improving the accuracy of the electrical property detection of the item to be tested.

[0127] The following example illustrates the pipeline process of testing the performance of the battery cover under test. Fig.13 As shown, the following steps are included:

[0128] S1301. Materials are ready.

[0129] The material is a battery cover to be tested, and the material is ready to be moved to a set position.

[0130] S1302, conduction test to determine the electrical connection detection result, if the electrical connection detection result is unqualified, execute S1306, if the electrical connection detection result is qualified, execute S1303.

[0131] S1303, switch short circuit test.

[0132] S1304, the high-voltage detection device performs a self-test test to determine the equipment self-test result. If the equipment self-test result fails, execute S1306; if the equipment self-test result passes, execute S1305.

[0133] S1305, short circuit test closed.

[0134] S1306: Issue an alarm message.

[0135] S1307, test the battery cover under test, if the performance test result fails, execute S1310, if the device self-test result passes, execute S1308.

[0136] S1308, scan the code to pass the station. If the code is scanned to pass the station, execute S1310. If the code is scanned to pass the station, execute S1309.

[0137] S1309, proceed to the next step.

[0138] S1310, material waste discharge.
