Description

Technical Field

[0001] The present application relates to the technical field of automobile parts testing, and in particular to a torque testing method, system, terminal and storage medium for an air outlet assembly. Background Art

[0002] The air outlet assembly is an important component in the automobile air conditioning system, which is mainly responsible for delivering cold or hot air into the car. The air outlet assembly is equipped with dampers and blades, which need to be controlled by corresponding knobs. Therefore, in order to ensure the normal use of dampers and blades, it is necessary to perform a torque test on the knob before the air outlet assembly leaves the factory to ensure that the torque required to rotate the knob is not too large.

[0003] Related technology When performing a torque test on an air outlet assembly, the air outlet assembly needs to be fixed in position first, and then a special torque tester is used to measure the torque required to rotate the knob on the air outlet assembly, and determine whether the torque is within a preset range.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are a variety of different types of knobs provided on the air outlet assembly, and each knob needs to be tested using a special torque tester, which results in too many steps in testing the air outlet assembly and low testing efficiency. Summary of the invention

[0005] In order to improve the testing efficiency of an air outlet assembly, the present application provides a torque testing method, system, terminal and storage medium for an air outlet assembly.

[0006] In a first aspect, the present application provides a method for testing the torque of an air outlet assembly, which adopts the following technical solution:

[0007] A method for testing the torque of an air outlet assembly, comprising:

[0008] According to the physical image of the air outlet assembly, detect the physical position of the knob to be tested;

[0009] When the actual position matches the first preset position, the manipulator is controlled to rotate the knob to be measured so that the knob to be measured rotates through a preset angle at a preset rate, and the torque value applied by the manipulator to the knob to be measured is continuously detected;

[0010] Obtain the torque peak value in the torque value;

[0011] If the torque peak is within the preset range, it is confirmed that the air outlet assembly has passed the torque test;

[0012] If the torque peak value is not within the preset range, it is confirmed that the air outlet assembly has failed the torque test.

[0013] By adopting the above technical solution, the manipulator tests the torque peak value of each knob to be tested on the air outlet assembly during the rotation process, and compares the torque peak value with the preset range to determine whether the air outlet assembly meets the requirements. The entire torque test process is completed by the manipulator, and there is no need to change the test instrument. The operation steps are few and the test efficiency is high.

[0014] Optionally, control the manipulator to lift the calibration object;

[0015] Obtain the calibration torque value applied by the manipulator on the calibration object;

[0016] Calculate the target torque value required to lift the calibration object according to the mass of the calibration object;

[0017] When the difference between the calibrated torque value and the target torque value is less than the preset difference, the step of detecting the physical position of the knob to be tested according to the physical image of the air outlet assembly is performed;

[0018] When the difference between the calibrated torque value and the target torque value is greater than the preset difference, an error signal is sent to the responsible terminal.

[0019] By adopting the above technical solution, before starting the torque test, the torque applied by the manipulator is calibrated to ensure that the manipulator can output accurate torque, which is conducive to accurately obtaining the torque value output by the manipulator.

[0020] Optionally, the knob to be measured is a knob in the air outlet assembly for controlling the direction of the blades, and the first preset position is the position of the knob to be measured when the blades are turned to the first end;

[0021] Controlling the manipulator to rotate the knob to be measured from a first preset position to a second preset position at a preset rate, wherein the second preset position is the position of the knob to be measured when the blade is turned to a second end, and the second end is opposite to the first end;

[0022] The manipulator is controlled to rotate the knob to be tested from the second preset position to the first preset position at a preset rate.

[0023] By adopting the above technical solution, the knob to be tested is rotated from the first end to the second end by a manipulator, so that the torque test process can detect various positions of the knob to be tested and obtain a more comprehensive torque value.

[0024] Optionally, a first torque value corresponding to the first timestamp and a second torque value corresponding to the second timestamp are obtained, a time difference between the first timestamp and the second timestamp matches a preset time difference, and the first torque value and the second torque value are within the preset interval;

[0025] Determining whether a torque difference between the first torque value and the second torque value is greater than a preset torque difference;

[0026] If not, return to the step of obtaining the first torque value and the second torque value;

[0027] If so, determining the position of the knob to be tested according to the first timestamp and the second timestamp;

[0028] Determine whether the position to be tested is the feedback position of the knob to be tested;

[0029] If yes, return to the step of obtaining the first torque value and the second torque value;

[0030] If not, a first abnormal signal is generated according to the position to be tested, and the first abnormal signal is used to indicate that the knob to be tested has a defect at the position to be tested.

[0031] By adopting the above technical solution, the torque difference between the first torque value and the second torque value within a short time difference is calculated to determine whether there is a defect inside the knob to be tested, which is beneficial to detecting abnormal conditions of the air outlet assembly.

[0032] Optionally, when the position of the real object does not match the first preset position, a first angle from the position of the real object to the first preset position and a second angle from the position of the real object to the second preset position are measured according to the image of the real object;

[0033] Determine the shape and structure of the knob to be tested through the real-object image;

[0034] According to the shape and structure of the knob to be tested, the manipulator is controlled to hold the knob to be tested;

[0035] When the first angle is smaller than the second angle, the manipulator is controlled to rotate the knob to be measured so that the knob to be measured rotates from the actual position to the first preset position;

[0036] When the first angle is greater than the second angle, the manipulator is controlled to rotate the knob to be measured so that the knob to be measured is rotated from the actual position to the second preset position.

[0037] By adopting the above technical solution, the knob to be tested is first rotated to the first preset position or the second preset position according to the physical image of the air outlet assembly to ensure that the air outlet assembly will not collide with the side wall of the knob to be tested during the process of rotating through the preset angle.

[0038] Optionally, detecting whether the first angle is greater than the third angle and less than the fourth angle;

[0039] If yes, the manipulator is controlled to rotate the knob to be tested toward the first preset position;

[0040] During the process of the knob to be tested rotating toward the first preset position, detecting whether the mean value of the torque value is less than the preset mean value;

[0041] If yes, generating a second abnormal signal according to the mean value of the torque values;

[0042] If not, the manipulator is controlled to rotate the knob to be tested toward the second preset position; during the process of rotating the knob to be tested toward the second preset position, it is detected whether the difference between the torque value when the knob to be tested is rotated and the average value of the torque value is greater than the preset torque error;

[0043] If yes, the manipulator is controlled to continue to rotate the knob to be tested, so that the knob to be tested is rotated to a second preset position;

[0044] If not, a third abnormal signal is generated according to the torque value when the rotation occurs.

[0045] By adopting the above technical solution, it is possible to detect whether the knob to be tested has a part with too little resistance, so as to ensure that the product quality of the air outlet assembly is qualified.

[0046] Optionally, the statistical torque value is less than the angle interval corresponding to the preset mean value;

[0047] In the historical test records of the air outlet assembly, find the historical torque value corresponding to the angle range;

[0048] Compare the historical torque value with the preset average value to generate the historical air outlet assembly detection result.

[0049] By adopting the above technical solution, the test records of the historical air outlet assembly are screened by angle range to find out whether there are defective parts in the historical air outlet assembly, thereby ensuring that the product quality of the historical air outlet assembly meets the requirements.

[0054] The program in the processor and the memory can be loaded and executed by the processor to implement any of the above-mentioned torque testing methods for the air outlet assembly.

[0055] By adopting the above technical solution, the manipulator tests the torque peak value of each knob to be tested on the air outlet assembly during the rotation process, and compares the torque peak value with the preset range to determine whether the air outlet assembly meets the requirements. The entire torque test process is completed by the manipulator, and there is no need to change the test instrument. The operation steps are few and the test efficiency is high.

[0074] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figures 1 to 8 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0075] The present application embodiment discloses a schematic diagram of an implementation scenario of a method for testing the torque of an air outlet assembly. Figure 1 , the implementation scenario includes: an air outlet assembly 1, a base, a camera 2, a manipulator 3 and a control terminal.

[0076] The air outlet assembly 1 includes a blade knob 11, a damper knob 12 and an air outlet 13. The air outlet 13 is an opening on the air outlet assembly 1 for outputting cold or hot air. Blades are arranged inside the air outlet 13, and the blades can adjust the flow direction of the air output by the air outlet assembly 1. The blade knob 11 is used to control the direction of the blades. A damper is arranged inside the air outlet assembly 1, and the damper is used to control the air flow entering the air outlet assembly 1. The damper knob 12 is used to control the opening degree of the damper.

[0077] The air outlet assembly 1 is mounted on the base, and the base is used to fix the air outlet assembly 1. A positioning hole is provided on the air outlet assembly 1, and bolts can be installed on the positioning hole to fix the air outlet assembly 1. Furthermore, the base can also rotate and move horizontally.

[0078] The camera 2 is used to capture the physical image of the air outlet assembly 1 .

[0079] The manipulator 3 is used to rotate the knob to be tested on the air outlet assembly 1. Optionally, a sensor is provided inside the manipulator 3, and the sensor includes a force sensor, a speed sensor, and an angle sensor. The manipulator 3 can control the knob to be tested to rotate at a preset speed through a preset angle. At this time, the torque applied by the manipulator 3 during the entire rotation process can be measured, and it can be determined whether the torque peak is within a preset range to obtain the torque test result of the air outlet assembly 1.

[0080] The control terminal is used to control other devices in the implementation scenario.

[0081] Exemplarily, after the air outlet assembly 1 is fixed on the base, the base will move in front of the camera 2 so that the camera 2 is aimed at the blade knob 11 on the air outlet assembly 1. The camera 2 photographs the air outlet assembly 1 to obtain a physical image, and determines whether the blade knob 11 is located at the first preset position through the physical image. If the blade knob 11 is located at the first preset position, the manipulator 3 is controlled to perform torque tests on the blade knob 11 and the damper knob 12 on the air outlet assembly 1 in sequence, and the torque value applied by the manipulator 3 during each torque test is recorded. The torque peak value in the torque value is obtained. If the torque peak value is within the preset interval, it is confirmed that the air outlet assembly 1 has passed the torque test; if the torque peak value is not within the preset interval, it is confirmed that the air outlet assembly 1 has not passed the torque test.

[0082] The present application embodiment discloses a flow chart of a method for testing the torque of an air outlet assembly. Figure 2 , the method comprising:

[0083] Step S201: Detecting the physical position of the knob to be tested according to the physical image of the air outlet assembly.

[0084] The actual image refers to the image of the knob to be tested on the air outlet assembly.

[0085] The physical position indicates the rotation position of the knob to be measured on the wind assembly. The two end points of the rotation range of the knob to be measured are the first preset position and the second preset position.

[0086] Step S202: when the actual position matches the first preset position, the manipulator is controlled to rotate the knob to be tested so that the knob to be tested rotates through a preset angle at a preset rate, and the torque value applied by the manipulator to the knob to be tested is continuously detected.

[0087] The preset angle is related to the rotatable range of the knob to be measured, and the preset angle is equal to the included angle between the first preset position and the second preset position.

[0088] The preset rate is a preset fixed value. The preset rate refers to the angular velocity of the knob to be measured.

[0089] Exemplarily, this step requires controlling the manipulator to rotate the knob to be measured through a preset angle. Since the preset angle is a fixed value, when the knob to be measured is not located at the first preset position, rotating the knob to be measured through the preset angle will cause the knob to be measured to exceed its rotatable range. Therefore, it is necessary to rotate the knob to be measured only when it is determined that the knob to be measured is in the first preset position. On the other hand, the knob to be measured includes a blade knob and a damper knob. Among them, a return spring is arranged inside the damper knob, and the return spring is used to maintain the damper knob in the first preset position. Therefore, when the knob to be measured is a damper knob, it is not necessary to detect whether the damper knob is located at the first preset position.

[0090] In an optional implementation, the manipulator is controlled to rotate the knob to be tested so that the knob to be tested rotates at a constant speed according to a preset rate. During the constant speed rotation of the knob to be tested, the torque applied to the knob to be tested by the manipulator is the same as the resistance inside the knob to be tested, so that the internal resistance of the knob to be tested can be obtained by measuring the torque value on the manipulator, and then it can be determined whether the internal resistance of the knob to be tested will affect the normal use of the knob to be tested.

[0091] Optionally, the knob to be measured is a knob in the air outlet assembly for controlling the direction of the blade, and the first preset position is the position of the knob to be measured when the blade is turned to the first end. Exemplarily, the manipulator is controlled to rotate the knob to be measured from the first preset position to the second preset position at a preset rate, the second preset position is the position of the knob to be measured when the blade is turned to the second end, and the second end is opposite to the first end; the manipulator is controlled to rotate the knob to be measured from the second preset position to the first preset position at a preset rate.

[0092] Step S203: obtaining the torque peak value in the torque value.

[0093] Optionally, while the manipulator is rotating the knob to be tested, the torque value applied by the manipulator and the timestamp corresponding to the torque value are recorded; a torque curve graph is drawn based on the torque value and the timestamp, and the torque curve graph is used to represent the relationship between the torque value and time; and the torque peak value is obtained from the torque curve graph.

[0094] Step S204: If the torque peak value is within the preset range, it is confirmed that the air outlet assembly has passed the torque test.

[0095] Optionally, the preset interval is related to the knob to be tested, and the knob to be tested includes a blade knob and a damper knob. For example, when the knob to be tested is a blade knob, the preset interval is [0.5N, 3N]; when the knob to be tested is a damper knob, the preset interval is [0.5N, 8N].

[0096] Step S205: If the torque peak value is not within the preset range, it is confirmed that the air outlet assembly has failed the torque test.

[0097] Furthermore, if the torque peak value is not within the preset range, an error detection signal is sent to the person in charge, and the error detection signal is used to indicate that the air outlet assembly has failed the torque test.

[0098] In summary, the manipulator tests the torque peak of each knob to be tested on the air outlet assembly during rotation, and compares the torque peak with the preset range to determine whether the air outlet assembly meets the requirements. The entire torque test process is completed by the manipulator, and there is no need to change the test instrument. The operation steps are relatively few and the test efficiency is high.

[0099] In the following embodiments, before the manipulator is put into torque testing, it is necessary to ensure that the torque value actually output by the manipulator is the same as the torque value measured. Therefore, the present application embodiment discloses a flow chart of a calibration method for a manipulator. Figure 3 , the method comprising:

[0100] Step S301: Control the robot to lift the calibration object.

[0101] Exemplarily, the calibration object is fixed to one end of a pulley by a rope, and the manipulator applies a torque to the pulley to rotate the pulley and lift the calibration object through the rope.

[0102] Exemplarily, the calibration object is a weight of fixed mass.

[0103] Step S302: Obtain the calibration torque value applied by the manipulator on the calibration object.

[0104] Optionally, the calibration torque value is the torque value applied by the manipulator to the calibration object when the calibration object is just lifted, or the calibration torque value is the torque value applied by the manipulator to the calibration object when the calibration object rises at a uniform speed.

[0105] Step S303: Calculate the target torque value required to lift the calibration object according to the mass of the calibration object.

[0106] Exemplarily, the gravity value of the calibration object is converted according to the mass of the calibration object; the torque distance from the calibration object to the center of the roller skates is obtained; the target torque is obtained by multiplying the gravity value of the calibration object by the torque distance; the target torque value required to lift the calibration object is obtained according to the ratio of the target torque to the distance from the position where the manipulator applies the torque to the center of the roller skates.

[0107] Step S304: when the difference between the calibrated torque value and the target torque value is less than the preset difference, executing the step of detecting the position of the knob to be detected according to the image of the air outlet assembly.

[0108] The preset difference is a preset fixed value, for example, the preset difference is 0.01N.

[0109] When the difference between the calibrated torque value and the target torque value is less than the preset difference, it means that the actual torque output by the manipulator is the same as the measured torque, and the manipulator passes the test.

[0110] Step S305: When the difference between the calibrated torque value and the target torque value is greater than the preset difference, an error signal is sent to the responsible terminal.

[0111] The error signal indicates that the actual torque output by the robot is different from the measured torque.

[0112] In some other implementation methods, the calibrated torque value of the manipulator is recalibrated according to the difference between the calibrated torque value and the target torque value.

[0113] Exemplarily, the responsible terminal is a computer terminal held by a technician closest to the robot.

[0114] In summary, before starting the torque test, the torque applied by the manipulator is calibrated to ensure that the manipulator can output accurate torque, which is conducive to accurately obtaining the torque value output by the manipulator.

[0115] In the following embodiments, the knob to be tested may produce a clicking sensation during rotation, which is due to the uneven resistance inside the knob to be tested. In severe cases, it may even affect the normal use of the knob to be tested. However, the peak torque applied by the manipulator is still within the preset range, which may result in the inability to detect the problem of the air outlet assembly. Therefore, the embodiment of the present application discloses a flow chart of a method for testing the torque of the air outlet assembly. Figure 4 , the method comprising:

[0116] Step S401: obtaining a first torque value corresponding to a first timestamp and a second torque value corresponding to a second timestamp, wherein a time difference between the first timestamp and the second timestamp matches a preset time difference, and the first torque value and the second torque value are within a preset interval.

[0117] The preset time difference is a preset value. Exemplarily, the preset time difference is 0.05s or 0.1s.

[0118] Exemplarily, the current time is taken as the first timestamp, and the first torque value corresponding to the first timestamp is obtained; after the current time passes a preset time difference, a second timestamp is obtained, that is, the sum of the first timestamp and the preset time difference is the second timestamp; and the second torque value corresponding to the second timestamp is obtained.

[0119] The timestamp in this application is used to record the specific time when the knob to be tested reaches a certain position after the manipulator starts to rotate the knob to be tested. The reference time of the timestamp is the time when the manipulator starts to rotate the knob to be tested, that is, the time when the manipulator starts to rotate the knob to be tested is recorded as 0.

[0120] Step S402: Determine whether the torque difference between the first torque value and the second torque value is greater than a preset torque difference.

[0121] If the torque difference between the first torque value and the second torque value is greater than the preset torque difference, executing steps S404 to S407;

[0122] If the torque difference between the first torque value and the second torque value is not greater than the preset torque difference, step S403 is executed.

[0123] The preset torque difference is a preset empirical value. For example, when the knob to be tested is a blade knob, the preset torque difference is 7N; when the knob to be tested is a throttle knob, the preset torque difference is 2.6N.

[0124] Step S403: If not, return to the step of obtaining the first torque value and the second torque value.

[0125] When the torque difference between the first torque value and the second torque value is not greater than the preset torque difference, it indicates that the knob to be tested does not have the phenomenon described above, and the process returns to step S401 to re-acquire the first torque value and the second torque value.

[0126] Step S404: If yes, the position of the knob to be tested is determined according to the first timestamp and the second timestamp.

[0127] When the torque difference between the first torque value and the second torque value is greater than the preset torque difference, it means that the knob to be tested does not have the phenomenon described above, and subsequent processing is required.

[0128] Exemplarily, a first angle is obtained according to the product of the first timestamp and the preset rate, and the first angle represents the angle between the position of the knob to be tested and the first preset position after the time length of the first timestamp has passed; a second angle is obtained according to the product of the second timestamp and the preset rate, and the second angle represents the angle between the position of the knob to be tested and the first preset position after the time length of the second timestamp has passed. The position to be tested of the knob to be tested refers to the range between the first angle and the second angle.

[0129] Step S405: determining whether the position to be tested is the feedback position of the knob to be tested.

[0130] If the position to be tested is the feedback position of the knob to be tested, step S406 is executed;

[0131] If the position to be tested is not the feedback position of the knob to be tested, step S407 is executed.

[0132] When the knob is in the feedback position, the knob will generate feedback to help the user confirm the position of the knob. For example, in actual products, when some knobs are turned to the feedback position, they will generate a "click" sound to remind the user. Therefore, it is necessary to first determine whether the position to be tested is the feedback position of the knob to be tested to exclude the possibility that the "click" sound is caused by the feedback position.

[0133] Step S406: If yes, return to the step of obtaining the first torque value and the second torque value.

[0134] If the position to be tested is the feedback position of the knob to be tested, it means that the torque difference in the above step is obtained based on, and the process returns to step S401 to re-acquire the first torque value and the second torque value.

[0135] Step S407: If not, a first abnormal signal is generated according to the position to be tested, and the abnormal signal is used to indicate that the knob to be tested has a defect at the position to be tested.

[0136] If the position to be tested is not the feedback position of the knob to be tested, it means that the torque difference in the above step is caused by an abnormality inside the knob to be tested.

[0137] Optionally, the first abnormal signal is sent to a terminal of a responsible person.

[0138] In summary, calculating the torque difference between the first torque value and the second torque value within a relatively short time difference to determine whether there is a defect inside the knob to be tested is helpful for detecting abnormal conditions of the air outlet assembly.

[0139] In the following embodiment, since the knob to be tested on the air outlet assembly needs to be rotated to a preset angle, but when the knob to be tested is not located at the first preset position, rotating the knob to be tested will cause it to exceed the original rotation range. Therefore, the embodiment of the present application discloses a flow chart of a method for testing the torque of the air outlet assembly. Figure 5 , the method comprising:

[0140] Step S501: when the position of the real object does not match the first preset position, measuring a first angle from the position of the real object to the first preset position and a second angle from the position of the real object to the second preset position according to the image of the real object.

[0141] Exemplarily, when the actual position does not match the first preset position, the knob to be tested needs to be rotated to the first preset position or the second preset position to prevent the knob to be tested from exceeding the rotatable range during subsequent rotation of the knob to be tested.

[0142] Step S502: determining the appearance structure of the knob to be tested through the physical image.

[0143] Exemplarily, the outer shape of the knob to be tested matches the shape of the manipulator, so that the manipulator can hold the knob to be tested. For example, the knob to be tested is provided with a pattern, and the manipulator is provided with a groove corresponding to the pattern, and when the manipulator holds the knob to be tested, the pattern fits into the knob to be tested.

[0144] Step S503: controlling the manipulator to hold the knob to be tested according to the appearance structure of the knob to be tested.

[0145] Exemplarily, according to the outer shape structure of the knob to be tested, the manipulator is controlled to match the shape structure of the knob to be tested, so that the manipulator can hold the knob to be tested.

[0146] Step S504: when the first angle is smaller than the second angle, the manipulator is controlled to rotate the knob to be measured, so that the knob to be measured is rotated from the actual position to the first preset position.

[0147] After the knob to be tested is rotated to the second preset position, when performing a torque test on the air outlet assembly, the knob to be tested can be rotated from the first preset position to the second preset position, and then rotated from the second preset position back to the first preset position.

[0148] Step S505: when the first angle is greater than the second angle, control the manipulator to rotate the knob to be measured, so that the knob to be measured rotates from the actual position to the second preset position.

[0149] It should be noted that after the knob to be tested is rotated to the second preset position, when performing a torque test on the air outlet assembly, the knob to be tested can be rotated from the second preset position to the first preset position, and then rotated from the first preset position back to the second preset position.

[0150] In summary, the knob to be tested is first rotated to the first preset position or the second preset position according to the physical image of the air outlet assembly to ensure that the air outlet assembly does not collide with the side wall of the knob to be tested when rotating through the preset angle.

[0151] In the following embodiments, the resistance of the knob on the air outlet assembly is too small, causing the knob to slide from the first preset position, resulting in the knob to be tested not being in the first preset position. Therefore, this factor also needs to be considered when performing a torque test. Therefore, the present application embodiment discloses a flow chart of a method for testing the torque of an air outlet assembly. Figure 6 , the method comprising:

[0152] Step S601: Detect whether the first angle is greater than the third angle and less than the fourth angle.

[0153] If the first angle is greater than the third angle and less than the fourth angle, step S602 is executed.

[0154] If the first angle is smaller than the third angle or larger than the fourth angle, it indicates that the resistance of the tested knob of the air outlet assembly is not too small.

[0155] The third angle and the fourth angle are preset angles. Exemplarily, the third angle is within the measurement error range. For example, the third angle is 1.5 degrees and the fourth angle is 7.0 degrees.

[0156] Step S602: If yes, control the robot arm to rotate the knob to be tested toward the first preset position.

[0157] The process of the manipulator rotating the knob to be tested toward the first preset position can be referred to Figure 1 The embodiments shown will not be described in detail here.

[0158] Step S603: When the knob to be tested rotates toward the first preset position, detecting whether the mean value of the torque value is less than a preset mean value.

[0159] If the mean value of the torque values ​​is less than the preset mean value, executing step S604;

[0160] If the mean value of the torque values ​​is not less than the preset mean value, step S605 to step S608 are executed.

[0161] The preset mean is a preset fixed value. In this step, it is necessary to determine the relationship between the mean value of the torque value and the preset mean value during the process of the tested knob rotating toward the first preset position, so as to determine whether the resistance between the physical position of the tested knob and the first preset position is too small. If the resistance in this range is too small, the tested knob may rotate unexpectedly, affecting the normal operation of the air outlet assembly.

[0162] Step S604: If yes, generate a second abnormal signal according to the mean value of the torque value.

[0163] The second abnormal signal is used to indicate that the resistance of the knob to be measured on the air outlet assembly is too small. Optionally, the second abnormal signal includes at least one of the number of the air outlet assembly, the position of the knob to be measured, the average value of the torque value, and the first angle.

[0164] Furthermore, a second abnormal signal is sent to the terminal of the person in charge.

[0165] Step S605: If not, control the robot arm to rotate the knob to be tested toward the second preset position.

[0166] The process of the manipulator rotating the knob to be tested toward the second preset position can be referred to Figure 1 The embodiments shown will not be described in detail here.

[0167] Step S606: When the knob to be tested rotates toward the second preset position, detecting whether the difference between the torque value when the knob to be tested rotates and the average value of the torque value is greater than a preset torque error.

[0168] If the difference between the torque value when the knob to be tested is rotated and the average value of the torque value is greater than the preset torque error, step S607 is executed;

[0169] If the difference between the torque value when the knob to be tested is rotated and the average value of the torque value is not greater than the preset torque error, step S608 is executed.

[0170] In the actual production process, the reason for the above-mentioned torque value being too small is usually that the air outlet assembly is injected unevenly during the manufacturing process, resulting in uneven contact between the knob to be tested and the body of the air outlet assembly. There is a high probability that the resistance of the knob to be tested is too small in a certain range, and too large in the next range. Therefore, this step will determine whether the small resistance between the physical position and the first preset position is caused by uneven injection molding by detecting whether the torque value when the knob to be tested is rotated is within the preset range.

[0171] Step S607: If yes, control the manipulator to continue rotating the knob to be tested, so that the knob to be tested rotates to a second preset position.

[0172] If the difference between the torque value when the knob to be tested rotates and the average torque value is greater than the preset torque error, it means that the resistance between the actual position and the first preset position is too small and is not caused by uneven injection molding. Further, similar processing can be performed on the remaining positions of the knob to be tested.

[0173] Step S608: If not, generating a third abnormal signal according to the torque value when the rotation occurs.

[0174] The third abnormal signal is used to indicate that the resistance of the knob to be tested on the air outlet assembly is too small. Optionally, the third abnormal signal includes at least one of the torque value when the knob to be tested rotates, the number of the air outlet assembly, the position of the knob to be tested, the average value of the torque value, and the first angle.

[0175] Furthermore, a third abnormal signal is sent to the terminal of the person in charge.

[0176] In summary, it is possible to detect whether the knob to be tested has a portion with too little resistance, so as to ensure that the product quality of the air outlet assembly is qualified.

[0177] In the following embodiments, since the problem of the above-mentioned knob to be tested is not easy to be detected, some air outlet assemblies may not be easy to be detected, so it is necessary to detect the torque value of the air outlet assembly that has completed the torque test. Therefore, the embodiment of the present application discloses a flow chart of a method for testing the torque of the air outlet assembly. Figure 7 , the method comprising:

[0178] Step S701: Count the angle intervals where the torque value is less than the preset mean value.

[0179] Optional, in Figure 6 After step S608 of the illustrated embodiment, the torque test may be continued for the rotatable range of the tested knob to obtain torque values ​​at various positions within the rotatable range, and obtain angle intervals corresponding to torque values ​​less than a preset mean value.

[0180] Step S702: searching for historical torque values ​​corresponding to the angle interval in historical test records of the air outlet assembly.

[0181] The historical air outlet assembly refers to an air outlet assembly that has completed the torque test. Optionally, the historical air outlet assembly is an air outlet assembly that has completed the torque test a before the current air outlet assembly, where a is a positive integer and the value of a can be adjusted according to actual needs.

[0182] Step S703: Compare the historical torque value with the preset average value to generate the historical air outlet assembly detection result.

[0183] Exemplarily, the number of torque values ​​in historical torque values ​​that are less than a preset average and the total number of historical torque values ​​are obtained; the ratio of the number of torque values ​​to the total number is calculated to obtain the torque value ratio; if the torque value ratio is less than the preset ratio, the historical air outlet assembly is regarded as a normal air outlet assembly; if the torque value ratio is greater than the preset ratio, the historical air outlet assembly is regarded as a problematic air outlet assembly.

[0184] In summary, the test records of historical air outlet assemblies are screened by angle range to find out whether there are any problematic parts in the historical air outlet assemblies, thereby ensuring that the product quality of the historical air outlet assemblies meets the requirements.

[0188] Processor 803, the program in the memory can be loaded and executed by the processor to implement any of the above-mentioned torque testing methods for the air outlet assembly.
