[0002] The detection accuracy of the detector is extremely important to ensure the quality and safety of the parts to be tested. In related technologies, the accuracy problem of the detector is usually discovered when the test results of the parts to be tested are incorrect during the detection process. The detection work of the detector is then completed by manually stopping the instrument, placing standard blocks, and operating the detector.

[0003] However, the above-mentioned detection of the detector is relatively passive. Once the detection result of the detected part is wrong, the manpower and material costs required to recover the incorrect part are high, and there is a great safety hazard if the incorrect part is not intercepted in time.

[0037] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0038] In the related art, a detector, such as a high-voltage impact tester, usually discovers the detection accuracy problem of the high-voltage impact tester only when the test result of the test piece is incorrect during the test process. The test work of the high-voltage impact tester is then completed by manually stopping the instrument, placing standard blocks, and operating the high-voltage impact tester.

[0039] For example, if the part to be tested is a lithium battery, a high-voltage impact tester is used to perform quality inspection on the lithium battery to detect whether the lithium battery has quality failures caused by poor insulation or defects of the isolation membrane caused by contamination, perforation and damage. However, due to the influence of working conditions such as damage to the detection probe of the high-voltage impact tester, poor contact between the probe and the test workpiece, and dirt on the probe and the connection surface, the detection accuracy of the high-voltage impact tester will be reduced. Once the above working conditions occur during the detection process of the high-voltage impact tester, unqualified lithium batteries will flow into subsequent processes. When the staff finds that the detection accuracy of the high-voltage impact tester has been reduced, they need to manually stop the instrument, place standard blocks, and operate the high-voltage impact tester to complete the detection of the high-voltage impact tester.

[0040] However, in the work of testing lithium batteries with the above-mentioned high-voltage impact tester, the high-voltage impact tester was not tested until it was found that the detection accuracy was reduced, resulting in a relatively passive detection of the high-voltage impact tester. The recovery of unqualified lithium batteries that flow into subsequent processes requires high manpower and material costs, and unqualified lithium batteries pose great safety hazards such as fire and explosion. At the same time, the detection of the high-voltage impact tester requires manual intervention and the detection mechanism is single, the cost is high, and the detection accuracy is low.

[0041] Therefore, by adopting the detection method of the production mechanism of the embodiment of the present invention, when the production mechanism works normally and the detector has a detection demand, the transport mechanism moves the standard block to the detector, controls the detector to perform a high-voltage impact test, and outputs the detection result of the part to be detected according to the voltage detection curve of the part to be detected, and determines the detection result of the detector according to the detection result of the part to be detected, so as to realize automatic execution of the detection work of the detector according to the detection result of the part to be detected, and adds a detection mechanism for determining the detection result of the detector according to the detection result of the part to be detected, without human intervention, ensuring the detection accuracy of the detector entering the working state, saving costs, and improving the accuracy of detection.

[0042] The above-mentioned production mechanism detection method is implemented based on the production mechanism detection framework. The production mechanism detection framework is illustrated below with examples.

[0043] First, if Figure 1, which is a detection framework diagram of a production mechanism according to an embodiment of the present invention. The detection framework of the production mechanism includes: a software control system 20, a programmable controller 21, a human-machine interface 22, a production mechanism 1 23, a production mechanism 2 26, a production mechanism 3 27, a production mechanism 3 ... 28, a standard block 29, a battery 30, a detector 24 and a transport mechanism 25.

[0044] Among them, the software control system 20, for example, is composed of a computer host computer equipped with relevant control software, which reads data from a PLC (Programmable Logic Controller) control system or a detector in a network communication manner, such as a high-voltage impact tester, and then runs a program to perform internal data processing to complete the judgment of the accuracy of the high-voltage impact tester, and outputs the measurement results to the PLC for processing.

[0045] The programmable controller 21 is equipped with a specific program in the on-site production, and outputs corresponding control signals according to the logic operation control, so as to complete the action control of grabbing and putting down of the handling mechanism, the action execution of the high-voltage impact testing mechanism, the data collection and processing of the relevant sensor signals, and the data interaction with the software control system.

[0046] The transport mechanism 25 is composed of various cylinders, servo motors, inverter motors, industrial robots and various sensors. It mainly completes the picking, placing and transferring of on-site products through the coordination of various motor transmission mechanisms and cylinder transmission mechanisms and the detection feedback of various sensors.

[0047] The human-machine interaction interface 22, the parameter settings of the equipment and the display device can manually control the actions of various mechanisms. For example, it can be used to set the timing of the test, or manually start the test process, or set the test to be performed after a certain number of parts to be tested are produced.

[0048] The detector 24, such as a high-voltage impact instrument, also known as a high-voltage impact tester, a high-voltage impact detector, an insulation pulse detector, an insulation pulse tester, etc., can detect poor insulation or defects of the isolation membrane caused by contamination, perforation, damage, etc. for lithium batteries. The working principle of the high-voltage impact instrument is that for a blade battery with good insulation of the diaphragm, its capacitance is equivalent to a parallel circuit composed of a capacitor and a resistor. At this time, the power of the blade battery depends on the capacitance and the resistance value of the high resistor. In this case, the high-voltage impact instrument applies a pulse voltage to both ends of the blade battery before injection, and judges the qualified and unqualified status of the battery by monitoring the boost curve, the voltage detection curve within the test time, and the discharge voltage detection curve, and sends the result to the software in a communication manner and transmits it to the PLC through IO (input / output, Input / Output) testing.

[0049] The standard block 29 is a high voltage impact test block similar to a blade battery having a standard voltage rise curve, a voltage detection curve for test time and a discharge voltage detection curve when a test pulse is applied at both ends thereof, and is a tool for judging the detection accuracy of a high voltage impact tester.

[0050] Production mechanism one 23, production mechanism two 26, production mechanism three 27 and production mechanism three...28 all belong to production mechanism 100. Production mechanism one 23 includes a detector 24 and a transport mechanism 25. Production mechanism two 26, production mechanism three 27 and production mechanism three...28 include other mechanisms for inspecting the parts to be inspected, for example, mechanisms for performing code scanning, weighing and multi-point laser inspection.

[0051] Based on the detection framework of the above production organization, the following is combined with Figure 1-Figure 3 The detection method of the production mechanism according to the embodiment of the present invention is described.

[0052] like Figure 2 FIG. 1 is a flow chart of a method for detecting a production mechanism according to an embodiment of the present invention. The method for detecting a production mechanism according to an embodiment of the present invention at least includes steps S1 to S3.

[0053] Step S1, when the production mechanism works normally and the detector has a detection requirement, the transport mechanism moves the standard block to the detector.

[0054] In an embodiment, Figure 1 As shown, the production mechanism can work normally, and the PLC determines whether the production mechanism needs to test the detector. The judgment conditions are various judgment bases set in the PLC program, such as preset time, preset time interval, production of a certain number of parts to be tested, and manual start through the human-computer interaction interface. To enable the PLC to judge whether the detector has a detection demand, the judgment basis is not fixed, and can be set in the human-computer interaction interface by the maintenance personnel of the detector according to the actual process requirements, etc., to avoid the time period when the detector performs detection work, such as performing detection work on the detector when the instrument is waiting for materials, so as to realize flexible and active detection of the detector and ensure the detection work of the detector.

[0055] When the programmable controller determines that the detector has a detection requirement based on the multiple judgment criteria set in the PLC program, it controls the transport mechanism to move the standard block to the detector to start testing the detector, ensuring the accuracy of the detector entering the working state. The above process does not require human intervention, saving costs and improving detection efficiency.

[0056] For example, for detectors such as high-voltage detection and impact testers, based on the premise that the production mechanism can work normally, the maintenance personnel of the high-voltage detection and impact tester can set the various judgment criteria set in the PLC program in the human-computer interaction interface as needed. The setting actions include adding, modifying, and deleting. The setting items include preset time, preset time interval, producing a certain number of parts to be tested, and manually starting through the human-computer interaction interface. When the PLC determines that the above settings are met, it will consider that the high-voltage detection and impact tester has a detection requirement, and will control the transport mechanism to move the standard block to the high-voltage detection and impact tester to start testing the high-voltage detection and impact tester.

[0057] Step S2, after controlling the detector to perform a high voltage impact test, output the detection result of the component to be detected according to the voltage detection curve of the component to be detected.

[0058] In an embodiment, Figure 1 As shown, the part to be tested is a device waiting for quality inspection by the detector. After the PLC determines that the detector has a detection demand, it will control the detector to perform a high-voltage impact test. During the test, the PLC will control the detector to apply a pulse voltage to both ends of the standard block. After applying the pulse voltage, the detector will generate a voltage detection curve of the part to be tested. The detector determines the preliminary detection result of the part to be tested based on the voltage detection curve, and sends the preliminary detection result to the PLC. The software control system will also obtain the preliminary detection result. The software control system will process the preliminary detection result accordingly and send it to the PLC. The PLC outputs the detection result of the part to be tested based on the preliminary detection result and the preliminary detection result processed by the software control system, which serves as a basis for judging the detection result of the detector, and obtains the detection result of the part to be tested through the preliminary detection result and the preliminary detection result processed by the software control system. This is an added detection mechanism, which improves the accuracy of the detection.

[0059] For example, the detector is a high-voltage detection impact tester, and the part to be detected is a lithium battery. After the PLC determines that the high-voltage detection impact tester has a detection requirement, it will control the high-voltage detection impact tester to perform a high-voltage impact test. During the test, the PLC will control the high-voltage detection impact tester to apply a pulse voltage to both ends of the standard block. After applying the pulse voltage, the high-voltage detection impact tester will generate a voltage detection curve for the lithium battery. The voltage detection curve includes: a battery boost curve, a voltage detection curve within the test time, and a discharge voltage detection curve. The high-voltage detection impact tester determines the preliminary detection results of the part to be detected based on the voltage detection curve. The preliminary detection results include: the battery is qualified and the battery is unqualified, and the preliminary detection results are sent to the PLC. The software control system will also obtain the preliminary detection results. The software control system will process the preliminary detection results accordingly and send them to the PLC. The PLC outputs the battery detection results based on the preliminary detection results and the preliminary detection results processed by the software control system.

[0060] Step S3, determining the detection result of the detector according to the detection result of the part to be detected.

[0061] In an embodiment, Figure 1 As shown, the PLC comprehensively judges the accuracy of the test results of the parts to be tested based on the test results of the parts to be tested. If the test results of the parts to be tested are accurate, the test result of the detector is determined to be that the test accuracy of the detector is up to standard and the parts can be put into operation. If the test results of the parts to be tested are inaccurate, the test result of the detector is determined to be that the test accuracy of the detector is not up to standard and the parts cannot be put into operation, so as to ensure the accuracy of the detector entering the working state and guarantee the test quality of the parts to be tested.

[0062] According to the detection method of the production mechanism of the embodiment of the present invention, when the production mechanism works normally and the detector has a detection demand, the transport mechanism moves the standard block to the detector, controls the detector to perform a high-voltage impact test, and outputs the detection result of the part to be detected according to the voltage detection curve of the part to be detected, and determines the detection result of the detector according to the detection result of the part to be detected, so as to realize automatic execution of the detection work of the detector on demand without human intervention, thereby ensuring the detection accuracy of the detector entering the working state, saving costs, and adding a detection mechanism for determining the detection result of the detector according to the detection result of the part to be detected, thereby improving the detection accuracy.

[0063] In some embodiments, outputting the detection result of the component to be detected according to the voltage detection curve of the component to be detected includes: obtaining the voltage detection curve of the component to be detected; obtaining the first detection result and the second detection result according to the voltage detection curve; and outputting the detection result of the component to be detected according to the first detection result and the second detection result.

[0064] In an embodiment, Figure 1 As shown, the voltage detection curve is the voltage detection curve generated by the detector after the PLC controls the detector to apply a pulse voltage to both ends of the standard block. The voltage detection curve includes: a battery boost curve, a voltage detection curve within the test time, and a discharge voltage detection curve. When the PLC receives the signal from the relevant sensor, it starts to comprehensively judge the status of the standard block in place and controls the production mechanism to perform corresponding actions, including: completing the fixation of the standard block, connecting the high-voltage impact probe on the detector to the positive pole, negative pole and shell of the battery, and controlling the detector to start applying a pulse voltage to both ends of the standard block to generate a voltage detection curve of the part to be detected. The detector obtains the voltage detection curve of the part to be detected to achieve a preliminary judgment of the detection result of the part to be detected.

[0065] The detector determines the preliminary inspection result of the part to be detected according to the voltage detection curve of the part to be detected, and outputs the first detection result and the second detection result. The PLC obtains the first detection result and the second detection result to determine the detection result of the part to be detected according to the first detection result and the second detection result.

[0066] The PLC obtains the first detection result output by the detector, and notifies the software control system to obtain the second detection result. The software control system processes the second detection result accordingly and outputs the processed second detection result, and transmits the processed second detection result to the PLC, so that the PLC can judge the detection result of the part to be detected based on the first detection result and the processed second detection result.

[0067] The PLC outputs the detection result of the to-be-detected part according to the first detection result and the processed second detection result, so as to judge the detection accuracy of the detector.

[0068] In some embodiments, obtaining the first detection result and the second detection result according to the voltage detection curve includes: determining the first detection result and the second detection result according to the voltage detection curve; and obtaining the first detection result and the second detection result according to the communication method.

[0069] In an embodiment, Figure 1 As shown, when the first test result and the second test result are obtained according to the voltage detection curve, the detector determines the preliminary inspection result of the part to be tested according to the voltage detection curve of the part to be tested, and the preliminary test results include: the part to be tested is qualified and the part to be tested is unqualified. The preliminary test result is divided into two parts, corresponding to the first test result and the second test result, so as to achieve corresponding processing of the second test result.

[0070] The first detection result and the second detection result are obtained according to the communication mode, and the communication mode includes the IO direct connection communication mode and the TCP communication mode. After the detection of the detector is completed, the PLC obtains the first detection result through the IO direct connection communication mode, and notifies the software control system to obtain the second detection result. The software control system performs corresponding processing on the second detection result to output the processed second detection result, and transmits the processed second detection result to the PLC. The corresponding processing includes: the software control system makes a comprehensive judgment on the second detection result through the transmitted detection message of the to-be-detected part and the relevant information of the to-be-detected part in the database, etc. If the result of the comprehensive judgment is the same as the received second detection result, the second detection result is output to the PLC. If the result of the comprehensive judgment is different from the received second detection result, the processed second detection result is output to the PLC. For example, the second detection result is that the to-be-detected part is qualified. After the software control system comprehensively judges that the to-be-detected part is unqualified, which is different from the received second detection result, the detection result of the unqualified part to be detected will be output as the processed second detection result to the PLC, so that the PLC judges the detection result of the to-be-detected part according to the first detection result and the processed second detection result, thereby improving the judgment accuracy of the detection result of the to-be-detected part.

[0071] In some embodiments, outputting the detection result of the part to be detected according to the first detection result and the second detection result includes: when the first detection result and the second detection result meet preset conditions, outputting the detection result of the part to be detected.

[0072] In an embodiment, Figure 1 As shown, when the test result of the part to be tested is output according to the first test result and the second test result, the PLC determines whether the preset conditions are met according to the first test result and the processed second test result. The preset conditions are conditions for judging whether the test results meet the standards, for example, whether the data formats of the two test results meet the standards and are the same, whether the two test results can pass the consistency comparison, etc. If the preset conditions are met, the test result of the part to be tested is output, and the test result of the test part includes: the part to be tested is qualified and the part to be tested is unqualified; if the preset conditions are not met, corresponding processing is performed, and the corresponding processing includes: re-acquiring the test results and analyzing the reasons for not meeting the consistency and solving them, etc. By judging whether the test results meet the preset conditions, the standardization and accuracy of the test results are ensured.

[0073] For example, if the first test result received by the PLC is that the part to be tested is qualified, and the second test result after processing is that the part to be tested is qualified, the PLC performs a data format comparison and consistency check, and obtains that the data formats of the above two test results are the same and meet the standards, and the two test results are consistent and both show that the part to be tested is qualified, then the output test result of the part to be tested is that the part to be tested is qualified; if the first test result received by the PLC is that the part to be tested is qualified, and the second test result after processing is that the part to be tested is unqualified, the PLC performs a data format comparison and consistency check, and obtains that the data formats of the above two test results are the same and meet the standards, but the two test results are inconsistent, then the cause of the inconsistency is analyzed and processed, and the output test result of the part to be tested is that the part to be tested is qualified or the part to be tested is unqualified.

[0074] In some embodiments, the detection result of the detector is determined according to the detection result of the detected piece, including: if the detection result of the detected piece is in the first detection state, it is determined that the detector has passed the quality inspection; if the detection result of the detected piece is in the second detection state, it is determined that the detector has failed the quality inspection.

[0075] In an embodiment, Figure 1 As shown, when determining the detection result of the detector according to the detection result of the part to be detected, the PLC determines that the detection result of the part to be detected is in the first detection state. The first detection state is to determine that the detection result of the part to be detected reaches the detection accuracy, determine that the detector has passed the quality inspection, and can be put into operation. The judgment condition is that the PLC comprehensively judges whether the detection result of the part to be detected is the correct quality state of the part to be detected based on the first detection result and the detection result of the part to be detected output after the processing of the second detection, combined with other information of the part to be detected. If it is the correct quality state of the part to be detected, it means that the detection result of the detector is accurate and meets the accuracy standard of the detection, and the detection result of the part to be detected is the first detection state. If it is not the correct quality state of the part to be detected, it means that the detection result of the detector is not accurate and does not meet the accuracy standard of the detection. The detection result of the part to be detected is the second detection state, and it is determined that the detector has failed the quality inspection. The state judgment of the detection result of the part to be detected can realize the judgment of the detection accuracy of the detector.

[0076] For example, the PLC determines that the inspection result of the piece to be inspected is unqualified based on the first inspection result and the processed second inspection output, and the inspection result of the piece to be inspected is unqualified based on other information of the piece to be inspected. If it is the correct quality status of the piece to be inspected, it means that the inspection result of the detector is accurate and meets the accuracy standard of the inspection, and the inspection result of the piece to be inspected is the first inspection status, and it is determined that the detector has passed the quality inspection and can be put into operation; the PLC determines that the inspection result of the piece to be inspected is unqualified based on the first inspection result and the processed second inspection output, and the inspection result of the piece to be inspected is qualified based on other information of the piece to be inspected. If it is an incorrect quality status of the piece to be inspected, it means that the inspection result of the detector is not accurate and does not meet the accuracy standard of the inspection, and the inspection result of the piece to be inspected is the second inspection status, and it is determined that the detector has failed the quality inspection and cannot be put into operation.

[0077] In some embodiments, controlling the detector to perform a high-voltage impact test includes: determining that the standard block moves to a detection position of the detector, and controlling the detector to apply test parameters to the standard block.

[0078] In an embodiment, Figure 1 As shown, when the detector is controlled to perform a high-voltage impact test, the PLC determines that the standard block moves to the detection position of the detector. The detection position is the position for placing the standard block set according to the needs, and judges the in-place status of the standard block. The in-place status is divided into in-place and out-of-place. If it is not in-place, the standard block will continue to be controlled to move to the detection position. If it is in-place, the detector is controlled to apply test parameters to the standard block. The test parameters include: applying a pulse voltage to both ends of the standard block to achieve the generation of a voltage detection curve.

[0079] In some embodiments, after determining that the detector has passed the quality inspection, the method further includes: after controlling the detector to move to an initial position, the transport mechanism controls the standard block to move to a preset storage position.

[0080] In an embodiment, Figure 1 As shown, the PLC determines that the test result of the test piece is in the first test state. After determining that the test instrument has passed the quality inspection, it controls the test instrument to move to the initial position, and controls the transport mechanism to move the standard block from the test position of the test instrument to the preset storage position. The preset storage position is the original storage position of the standard block. At the same time, the corresponding flag bits in the used software program are reset, etc., to restore the normal production state, so as to realize the reset of the used devices and software, and facilitate the management of the devices and the next use.

[0081] In some embodiments, after determining that the detector fails the quality inspection, the method further includes: issuing an alarm message indicating that the detection fails.

[0082] In an embodiment, Figure 1As shown, the PLC judges that the test result of the test piece is in the second test state, and after determining that the quality inspection of the detector is unqualified, an alarm message of unqualified detection is issued. For example, the PLC controls the buzzer to output an alarm sound effect, and the touch screen on the on-site software control system displays an alarm description. At this time, the inspection of the test piece is stopped, and on-site professionals check the fault of the detector to achieve timely discovery and processing of unqualified detectors.

[0083] In some embodiments, after issuing an alarm message indicating a failed test, the method further includes: obtaining a piece to be tested that outputs a first test result in the last test and outputs a second test result in the current test, and marking the piece to be tested.

[0084] In an embodiment, Figure 1 As shown, after an alarm message of unqualified detection is issued, the software control system is used to obtain the parts to be detected between the first detection result outputted last time and the second detection result outputted currently, that is, the parts to be detected between the parts to be detected that passed the last detection and the parts to be detected that failed the current detection, and the parts to be detected are marked, and the marked parts to be detected are processed accordingly, such as retrieving the parts to be detected for retesting, etc., so as to achieve efficient processing of the parts to be detected that do not meet the detection accuracy standards.

[0085] In some embodiments, the detector has a detection requirement including: the detection time reaches a preset time and / or the production quantity of the parts to be detected reaches a preset quantity and / or a detection instruction is received.

[0086] In an embodiment, Figure 1 As shown, when the detection time reaches the preset time, the maintenance personnel of the detector sets it in the human-computer interaction interface according to the actual process requirements, and avoids the time period in which the detector performs detection work, such as performing detection work on the detector when the instrument is waiting for material; when the production quantity of the parts to be detected reaches the preset quantity, the maintenance personnel of the detector sets it in the human-computer interaction interface according to the actual process requirements, and performs detection on the detector after the number of parts to be detected by the detector reaches; when the detection instruction is received, it is a command to manually start the detection of the detector sent by the software control system, so as to realize flexible and active detection of the detector and ensure the detection work of the detector.

[0094] Step S55, obtaining a voltage detection curve of the component to be detected.

[0095] Step S56, obtaining a first detection result and a second detection result according to the voltage detection curve.

[0096] Step S57, whether the first detection result and the second detection result meet the preset condition. If yes, execute step S59; otherwise, execute step S58.

[0097] Step S58, perform corresponding processing.

[0098] Step S59, outputting the test results of the test piece.

[0099] Step S60, whether the detection result of the detection component is the first detection result. If so, execute step S61; otherwise, execute step S63.

[0100] Step S61: the detector passes the quality inspection.

[0101] Step S62, controlling the detector to move to the initial position, and the transport mechanism to control the standard block to move to the preset storage position.

[0102] Step S63: the detection result of the component to be detected is the second detection result.

[0103] Step S64: the detector fails the quality inspection.
