Description

Technical Field

[0001] This invention relates to the field of automotive parts, and more particularly to a steering knuckle alignment method and system. Background Technology

[0002] Steering knuckle alignment typically refers to ensuring the accurate installation position of the steering knuckle during automotive repair or assembly to guarantee the proper functioning of the steering system and vehicle driving safety.

[0003] In existing technology, after the steering knuckle is manufactured, the alignment of the holes in the steering knuckle needs to be checked before installation. During the alignment process, relevant testing devices are usually used to check the alignment of the holes.

[0004] Regarding the aforementioned technologies, when using a testing device to align and test the holes in the steering knuckle, due to the different structures of different steering knuckles, workers need to manually place the steering knuckle into the testing device to test the holes. In each step of placing the steering knuckle, workers' participation is required, which reduces work efficiency and needs to be improved. Summary of the Invention

[0005] To improve work efficiency, this invention provides a steering knuckle alignment method and system.

[0006] In a first aspect, the present invention provides a steering knuckle alignment method, which adopts the following technical solution:

[0007] A steering knuckle alignment method, comprising:

[0008] Acquire the detection signal within the preset detection area;

[0009] The determination of whether to continue acquiring detection signals or acquire detection image information is based on the consistency between the detection signal and the preset placement signal;

[0010] The steering knuckle placement status is identified from a pre-set model database based on the detected image information;

[0011] Determine whether the steering knuckle placement is consistent with the preset reference placement.

[0012] If the steering knuckle placement is inconsistent with the reference placement, the placement anomaly type will be matched from the preset anomaly database based on the steering knuckle placement.

[0013] Based on the type of placement anomaly, a correction method is matched from the preset correction database, and the steering knuckle is corrected using the correction method.

[0014] If the steering knuckle placement is consistent with the reference placement, the preset clamping device will clamp and place the steering knuckle into the preset alignment device and output an alignment signal.

[0015] The alignment device is controlled to perform alignment detection on the steering knuckle with a preset alignment force and a preset alignment angle based on the alignment signal, and the detection pressure value of the alignment device is obtained.

[0016] The determination of whether to complete the test or report a prompt is based on the relationship between the detected pressure value and the preset benchmark pressure value.

[0017] By employing the above technical solution, the placement status of the steering knuckle can be determined by understanding the consistency between the detection signal and the placement signal after the steering knuckle is placed in the detection area. By acquiring detection image information, the consistency between the steering knuckle placement state and the reference placement state can be determined. If there is a discrepancy, the type of placement anomaly is identified to match a correction method, and the steering knuckle is then corrected. If there is a consistency, the steering knuckle is clamped and placed into the alignment device using a clamping device, and the steering knuckle is aligned. Finally, the detection status is determined by understanding the relationship between the detection pressure value and the reference pressure value. This reduces the need for manual intervention and improves work efficiency.

[0018] Optionally, placement anomaly types include rotational placement anomalies, and methods for correcting rotational placement anomalies include:

[0019] Determine if the placement anomaly type matches the preset rotation placement anomaly;

[0020] If the placement anomaly type is inconsistent with the rotation placement anomaly, a notification will be sent.

[0021] If the placement anomaly type is consistent with the rotation placement anomaly, then the location is identified and defined as the identification feature position from the detection image information based on the preset reference features.

[0022] The rotation vector is determined based on the identified feature position and the reference position corresponding to the reference feature;

[0023] The rotation vector is used to control the turntable on the correction device to perform rotational correction.

[0024] By employing the above technical solution, the anomaly type is corrected by understanding the consistency between placement anomalies and rotational placement anomalies. When they are consistent, the anomaly location is identified and defined as a recognition feature position in the detection image information. Then, by identifying the feature position and the reference position corresponding to the reference feature, the rotation vector is determined, thereby controlling the turntable on the correction device to rotate and correct the steering knuckle with rotational placement anomalies. This reduces the correction time and improves work efficiency.

[0025] Optionally, placement anomaly types also include location placement anomalies, and the correction methods for location placement anomalies include:

[0026] When the placement anomaly type is consistent with the preset placement anomaly, the tilt direction is determined based on the steering knuckle placement state and the reference placement state.

[0027] Obtain the steering knuckle weight value;

[0028] The tilt angle is determined based on the steering knuckle placement, the reference placement, and the steering knuckle weight.

[0029] The tilting and raising of the turntable on the corrective device is controlled according to the tilting direction and tilting angle.

[0030] Based on the tilting and lifting, the top height position of the steering knuckle and the water level information are obtained;

[0031] The inflation volume is determined by matching the water level height information with the height position of the apex from a preset inflation database.

[0032] Based on the inflation volume, the preset inflation airbag is inflated to raise the water level in the detection area, so that the liquid submerges the steering knuckle;

[0033] After inflation, the flushing force value is matched from the preset flushing database based on the tilt angle and the weight of the steering knuckle.

[0034] The location of the flushing force is determined based on the tilt direction and the weight of the steering knuckle.

[0035] The preset flushing device is controlled to flush the position of the object with water force to complete the movement correction.

[0036] By employing the above technical solution, the tilt direction is determined by comparing the steering knuckle's placement state with its reference placement state. The tilt angle is then calculated using the steering knuckle's placement state, reference placement state, and weight. The steering knuckle is then tilted and raised based on the tilt direction and angle. After raising, the airbag is inflated according to its volume, raising the water level to submerge the steering knuckle. This makes the steering knuckle more easily actuated, and the movement is corrected by matching the water pressure and the location of the water flow. This reduces the difficulty of correcting abnormal steering knuckle placement and further improves work efficiency.

[0037] Optional, also includes:

[0038] When the detection signal and the placement signal are consistent, the area of ​​the weight force within the detection region is obtained;

[0039] The determination of whether to complete the detection or output an abnormal force signal is based on the consistency between the weight-bearing area and the preset reference force-bearing area.

[0040] Based on the abnormal force signal, the water output force value is matched from the preset water output database according to the weight value of the steering knuckle;

[0041] The water outlet distance is determined based on the water pressure value;

[0042] Update the vertex height position based on the water outlet distance;

[0043] The inflation volume is updated based on the updated vertex height position;

[0044] Based on the updated inflation volume, the inflation of the airbag is controlled to raise the water level in the detection area to the updated apex height position;

[0045] The weight distribution of the steering knuckle is determined based on the area of ​​force application and the weight value of the steering knuckle.

[0046] The current center of gravity and the area of ​​force applied by water jetting are determined based on the weight distribution of the steering knuckle.

[0047] The adjustment parameters are determined based on the current center of gravity of the steering knuckle and the preset reference center of gravity of the steering knuckle.

[0048] Adjusting parameters and water pressure values ​​controls the preset flushing device to flush water through the outlet on the turntable into the area subject to the flushing force, thereby correcting the current center of gravity of the steering knuckle.

[0049] By employing the above technical solution, the placement posture of the steering knuckle is determined by understanding the consistency between the weight-bearing area and the reference weight-bearing area. When an abnormal placement posture occurs, the apex height position is updated by knowing the water outlet distance to prevent water from spraying out of the liquid surface during flushing. The updated apex height position is used to update the inflation volume, and the inflation bladder is controlled to raise the water level in the detection area to the updated apex height position. After the steering knuckle is submerged, the current center of gravity and the water-bearing stress area of ​​the steering knuckle are determined by understanding the weight distribution, thus allowing for parameter adjustments to correct the steering knuckle's center of gravity. This reduces abnormal steering knuckle postures and improves work efficiency.

[0050] Optional, also includes:

[0051] The flushing force value is determined based on the weight of the steering knuckle.

[0052] The flushing force value is used to control the preset flushing equipment to flush the steering knuckle and update the water level information, and the turntable is controlled to rotate one revolution at a preset rotation speed.

[0053] Based on the fact that the placement anomaly type is consistent with the rotation placement anomaly and after one rotation, the control flushing equipment stops flushing and stops updating the water level information;

[0054] Based on the discrepancy between the placement anomaly type and the rotation placement anomaly, and after one rotation, the flushing equipment is controlled to continue flushing, and the apex height position is lowered according to the updated water level information.

[0055] The inflation volume is updated based on the height of the apex after descent, and the flushing equipment is controlled to stop flushing.

[0056] By employing the above technical solution, the flushing force during steering knuckle flushing is determined by understanding the steering knuckle's weight. This flushing force is then used to control the flushing equipment. Furthermore, after flushing, the water level information is updated based on the type of steering knuckle placement anomaly, thereby updating the apex height position. This prevents excessive water level from causing liquid overflow into the detection area.

[0057] Optional, also includes:

[0058] Determine whether the water level information falls within the preset reference height range;

[0059] If the water level information exceeds the maximum value of the reference height range, the difference between the water level information and the maximum value of the reference height range is calculated, and the difference is defined as the drainage volume value.

[0060] The preset drainage device is activated based on the drainage volume value to discharge the liquid exceeding the water level into a preset storage tank.

[0061] If the water level information does not reach the minimum value of the reference height range, the difference between the water level information and the minimum value of the reference height range is calculated, and the difference is defined as the water replenishment volume.

[0062] The flushing equipment is controlled to replenish water to the detection area based on the water replenishment volume, so as to raise the water level to within the reference height range.

[0063] By employing the above technical solution, and understanding the relationship between the water level information and the reference height range, the method for adjusting the water level within the detection area can be determined. When the water level information exceeds the maximum value of the reference height range, the calculated drainage volume is used to control the drainage device to discharge the excess liquid into a storage tank for storage. When the water level information is below the minimum value of the reference height range, the calculated replenishment volume is used to control the flushing equipment to discharge liquid from the storage tank into the detection area. This improves the water utilization rate within the detection area.

[0064] Optional methods for transporting the rinsed item include:

[0065] After rinsing is completed, the clamping device is controlled to clamp and transport the steering knuckle at a preset clamping position and the position of the clamping device is obtained.

[0066] Determine whether the position of the clamping device falls within the preset drying area;

[0067] If the position of the clamping device does not fall into the drying area, continue to obtain the position of the clamping device;

[0068] If the clamping device falls into the drying area, the preset blowing device in the drying area will be activated, and the steering knuckle parameters will be obtained.

[0069] The position of the steering hole is determined based on the steering knuckle parameters and the reference placement.

[0070] The blowing device is controlled to blow dry the turning hole position at a preset blowing temperature according to the turning hole position.

[0071] After the air drying process, the control clamping device clamps the steering knuckle into the alignment device and then turns off the air blowing device.

[0072] By adopting the above technical solution, after the steering knuckle is washed, the position of the clamping device and its placement in the drying area determine whether the blower is activated. Once in place, the blower is activated, and by monitoring the position of the steering hole, the blower is controlled to dry the area. After drying, the blower is deactivated. This reduces energy consumption.

[0073] Optionally, after confirming that the detected pressure value does not exceed the reference pressure value, further testing methods include:

[0074] When the detected pressure value exceeds the reference pressure value, the location of the abnormal hole is determined according to the detection pin number of the preset detection pin on the alignment device.

[0075] Based on the location of the abnormal hole, output the abnormal hole location signal to the preset signal transceiver terminal;

[0076] When the detected pressure value does not exceed the reference pressure value, the preset telescopic device on the detection pin is controlled to extend in all directions with a preset extension force value to obtain the gap distance value.

[0077] Determine whether the gap distance value is consistent with the preset reference distance value;

[0078] If the gap distance value is consistent with the reference distance value, the detection completion signal of the steering hole corresponding to the current detection pin number is output to the signal transceiver terminal.

[0079] If the gap distance value is inconsistent with the reference distance value, then the signal indicating that the steering hole is too large or too small will be output to the signal transceiver terminal according to the relationship between the gap distance value and the reference distance value.

[0080] By adopting the above technical solution, when the detected pressure value exceeds the reference pressure value, the location of the abnormal hole can be determined by understanding the detection pin number. When the detected pressure value does not exceed the reference pressure value, the pass / fail status of the steering hole can be determined by understanding the consistency between the clearance distance value and the reference distance value. When it fails, the specific reason for the steering hole's failure can be determined by understanding the relationship between the clearance distance value and the reference distance value. This improves the accuracy of steering hole detection.

[0081] Optionally, the inspection method before the steering knuckle is placed into the inspection area includes:

[0082] Obtain image information of the steering knuckle before detection;

[0083] The consistency between the pre-detection image information and the preset reference image information determines whether to complete the detection or identify and mark surface defect features;

[0084] Based on surface defect characteristics, the defect type is identified from a pre-defined defect category library. The defect types include dent defects and boss defects.

[0085] Based on the boss defect, the control clamping device clamps the steering knuckle to the preset rework area for rework, and after the rework is completed, the control clamping device clamps the steering knuckle back to the detection area.

[0086] Based on the dent defect, the control clamping device clamps the steering knuckle to the preset recovery area and reports a prompt.

[0087] By employing the above technical solution, the surface defects of the steering knuckle can be determined by understanding the consistency between the pre-inspection image information and the reference image information. When surface defect characteristics are present, the method for handling the defect is determined by understanding the defect type. For boss defects, the steering knuckle is clamped to the rework area for repair, and after repair, the clamping device is controlled to clamp the steering knuckle back to the inspection area. For dent defects, the steering knuckle is clamped to the recycling area and a notification is reported. This improves the yield rate of steering knuckles.

[0088] Secondly, this application provides a steering knuckle alignment system, which adopts the following technical solution:

[0089] A steering knuckle alignment system, comprising:

[0090] The acquisition module is used to acquire detection signals, detection image information, detection pressure values, steering knuckle weight values, apex height position, water level height information, weight force area, clamping device position, steering knuckle parameters, and image information before detection.

[0091] A memory for storing the program for any of the above-mentioned steering knuckle alignment methods;

[0092] The processor and the program in the memory can be loaded and executed by the processor to implement any of the above-mentioned steering knuckle alignment methods.

[0093] By employing the above technical solution, the placement status of the steering knuckle can be determined by understanding the consistency between the detection signal and the placement signal after the steering knuckle is placed in the detection area. By acquiring detection image information, the consistency between the steering knuckle placement state and the reference placement state can be determined. If there is a discrepancy, the type of placement anomaly is identified to match a correction method, and the steering knuckle is then corrected. If there is a consistency, the steering knuckle is clamped and placed into the alignment device using a clamping device, and the steering knuckle is aligned. Finally, the detection status is determined by understanding the relationship between the detection pressure value and the reference pressure value. This reduces the need for manual intervention and improves work efficiency.

[0094] In summary, this application includes at least one of the following beneficial technical effects:

[0095] 1. By understanding the placement of the steering knuckle, the steering knuckle can be adjusted accordingly, and after adjustment, the alignment of the steering knuckle can be checked to improve work efficiency;

[0096] 2. By using an inflatable airbag and flushing equipment, the steering knuckle is submerged in liquid, thereby reducing the difficulty of steering knuckle alignment and improving work efficiency;

[0097] 3. By understanding the clearance distance value, we can determine the quality of the steering hole, thereby improving the accuracy of steering hole inspection. Attached Figure Description

[0102] Figure 5 This is a structural diagram of the correction device in an embodiment of the present invention. Detailed Implementation

[0103] The following is in conjunction with the appendix Figures 1-5 The invention will be further described in detail with reference to the embodiments.

[0104] This application discloses a steering knuckle alignment method. By understanding the steering knuckle's placement state, it corrects any abnormalities in the steering knuckle's placement. After correction, an alignment device is controlled to perform alignment detection on the steering knuckle. When the placement abnormality is a rotational placement abnormality, rotational correction is performed using a turntable 5 on the correction device 1. When the placement abnormality is a positional placement abnormality, an airbag 2 is inflated to raise the water level, and then the steering knuckle is flushed using a flushing device to complete the movement correction. When the steering knuckle's center of gravity is abnormal, the flushing device 9 is controlled to flush the force-bearing area to correct the steering knuckle's current center of gravity. Furthermore, when the steering knuckle is placed in the detection area, it is flushed using a rinsing device 6. When the water level in the detection area is abnormal, adjustments are made based on the type of abnormality. After flushing, the steering knuckle is clamped in a drying area for drying. After drying, the steering knuckle is aligned, and the detection results are output.

[0105] Reference Figure 1 and Figure 5 A steering knuckle alignment method includes the following steps:

[0106] Step 100: Obtain the detection signal within the preset detection area.

[0107] The detection area refers to the area used to detect the placement of the steering knuckle. The detection area is predetermined by those skilled in the art and will not be elaborated upon here. The detection signal is the signal indicating whether the steering knuckle is placed within the detection area. The detection signal is acquired through a signal transmitter.

[0108] Step 101: Determine whether to continue acquiring the detection signal or acquire the detection image information based on the consistency between the detection signal and the preset placement signal.

[0109] The placement signal refers to the signal indicating that the steering knuckle is placed within the detection area. The placement signal is pre-set by those skilled in the art and will not be elaborated upon here. The presence of a steering knuckle within the detection area is determined by judging the consistency between the detection signal and the placement signal.

[0110] If the detection signal is inconsistent with the placement signal, it means that there is no steering knuckle in the detection area, and you can continue to acquire the detection signal.

[0111] If the detection signal matches the placement signal, it indicates the presence of a steering knuckle within the detection area, and detection image information needs to be acquired. Detection image information refers to an image containing the steering knuckle within the detection area. Detection image information is acquired by taking pictures with a camera.

[0112] Step 102: Identify the steering knuckle placement status from the preset model database based on the detected image information.

[0113] The steering knuckle placement state refers to the posture of the steering knuckle within the detection area. This placement state can be identified from the detection image information using a model database. This model database is obtained through deep learning based on a neural network model and contains steering knuckle placement states. The model database is a manually configured database and will not be elaborated upon here.

[0114] Step 103: Determine whether the steering knuckle placement is consistent with the preset reference placement.

[0115] The reference placement state refers to the reference posture of the steering knuckle placed within the detection area. By determining whether the steering knuckle placement state is consistent with the reference placement state, it can be determined whether the steering knuckle is placed correctly.

[0116] Step 1031: If the steering knuckle placement state is inconsistent with the reference placement state, the placement anomaly type is matched from the preset anomaly database according to the steering knuckle placement state.

[0117] If the steering knuckle's placement is inconsistent with the reference placement, it indicates that the steering knuckle is not properly positioned and its placement needs to be corrected. Placement anomaly types refer to abnormal placement conditions of the steering knuckle. An anomaly database can be used to match the steering knuckle's placement state with the corresponding anomaly type. This anomaly database is obtained based on deep learning using a neural network model and contains placement anomaly types. The anomaly database is manually configured and will not be elaborated upon here.

[0118] Step 10311: Match the correction method from the preset correction database according to the placement anomaly type, and correct the steering knuckle according to the correction method.

[0119] The correction method refers to the method used to correct a misaligned steering knuckle. A correction database can be used to match the type of misalignment with the corresponding correction method. The correction database contains the correspondence between misalignment types and correction methods. This database is manually configured and will not be elaborated upon here. The matched correction method controls a preset correction device 1 to correct the steering knuckle. Correction device 1 is a device used to correct abnormal steering knuckle posture.

[0120] Step 1032: If the steering knuckle placement state is consistent with the reference placement state, control the preset clamping device to clamp and place the steering knuckle into the preset alignment device and output an alignment signal.

[0121] If the steering knuckle's placement matches the reference placement, it indicates that the steering knuckle is properly positioned. The clamping device can then be directly controlled to clamp the steering knuckle into the alignment device and output an alignment signal. The clamping device refers to the robotic arm used to move the steering knuckle. The alignment device is the device used to check the alignment of the steering knuckle. The alignment signal is the signal received after the steering knuckle is placed in the alignment device. The alignment signal is output through a transceiver installed on the alignment device.

[0122] Step 10321: Based on the alignment signal, control the alignment device to perform alignment detection on the steering knuckle with a preset alignment force and a preset alignment angle, and obtain the detection pressure value of the alignment device.

[0123] After the alignment signal is output, the alignment device is controlled to perform alignment detection on the steering knuckle using alignment force and alignment angle, and the detection pressure value of the alignment device is obtained. The alignment force refers to the force with which the detection pin on the alignment device enters the steering hole on the steering knuckle. The alignment angle refers to the angle at which the detection pin enters the steering hole. Both the alignment force and alignment angle are preset by those skilled in the art and will not be elaborated here. The detection pressure value refers to the pressure exerted by the detection pin on the steering knuckle during the detection process, and the detection pressure value is obtained by a pressure sensor on the alignment device.

[0124] Step 10322: Determine whether to complete the test or report a prompt based on the relationship between the detected pressure value and the preset reference pressure value.

[0125] The reference pressure value refers to the maximum pressure value that the detection pin on the alignment device can have. By judging the relationship between the detection pressure value and the reference pressure value, we can know whether the steering hole on the steering knuckle is qualified.

[0126] If the tested pressure value does not exceed the reference pressure value, it means that the current steering hole is qualified and the test can be completed.

[0127] If the detected pressure value exceeds the reference pressure value, it indicates that the current steering hole is unqualified and a report should be submitted.

[0128] Reference Figure 2 and Figure 5 The types of placement anomalies include rotational placement anomalies, and the correction methods for rotational placement anomalies include the following steps:

[0129] Step 200: Determine whether the placement anomaly type is consistent with the preset rotation placement anomaly.

[0130] Rotary placement anomaly refers to an abnormality where the steering knuckle is misaligned within the detection area. By comparing the placement anomaly type with that of a rotary placement anomaly, it can be determined whether the steering knuckle's placement anomaly is indeed a rotary placement anomaly.

[0131] Step 201: If the placement anomaly type is inconsistent with the rotation placement anomaly, report a prompt.

[0132] If the placement anomaly type is inconsistent with the rotational placement anomaly type, it means that the steering knuckle placement anomaly type is not a rotational placement anomaly, and a report should be submitted.

[0133] Step 202: If the placement anomaly type is consistent with the rotation placement anomaly, then identify and define the identification feature position from the detection image information according to the preset reference features.

[0134] If the placement anomaly type is consistent with the rotational placement anomaly, it indicates that the steering knuckle placement anomaly type is a rotational placement anomaly. It is necessary to identify the reference features through the detection image information, and define the reference features of the current steering knuckle in the detection image information as the identification feature position. Reference features refer to features used to assist in determining the position of various features of the steering knuckle. Reference features are preset by those skilled in the art and will not be elaborated upon here. The identification feature position refers to the position of the reference features of the current steering knuckle.

[0135] Step 2021: Determine the rotation vector based on the identified feature position and the reference position corresponding to the reference feature.

[0136] The rotation vector refers to the direction and angle when the steering knuckle is rotated for correction. The reference position refers to the position of the reference feature. By identifying the feature position and the reference position corresponding to the reference feature, the angle difference between the identified feature position and the reference position can be determined, and thus the rotation vector can be determined.

[0137] Step 2022: Rotate and correct the turntable 5 on the correction device 1 according to the rotation vector.

[0138] The steering knuckle is rotated and corrected by controlling the turntable 5 on the correction device 1 with a matched rotation vector. A rotating shaft 3 is provided under the turntable 5, and the rotation of the turntable 5 is controlled by controlling the rotation of the rotating shaft 3.

[0139] Reference Figure 3 and Figure 5 The types of placement abnormalities also include location placement abnormalities, and the methods for correcting location placement abnormalities include the following steps:

[0140] Step 300: When the placement anomaly type is consistent with the preset position placement anomaly, determine the tilt direction based on the steering knuckle placement state and the reference placement state.

[0141] An abnormal positioning refers to the steering knuckle not being placed in the center of the detection area. When the type of abnormal positioning is consistent with the abnormal positioning, the tilt direction can be determined by the steering knuckle positioning status and the reference positioning status. The tilt direction refers to the direction in which turntable 5 tilts when the steering knuckle needs to be tilted.

[0142] Step 301: Obtain the steering knuckle weight value.

[0143] The steering knuckle weight value refers to the weight of the steering knuckle. The steering knuckle weight value is obtained through a weight sensor located in the detection area.

[0144] Step 302: Determine the tilt angle based on the steering knuckle placement, the reference placement, and the steering knuckle weight.

[0145] The tilt angle refers to the angle at which turntable 5 is tilted. By observing the steering knuckle's placement and reference placement, the distance the steering knuckle needs to move to the center of the detection area can be determined. Then, by using the steering knuckle's weight and this distance, the tilt angle can be determined to ensure that the steering knuckle does not tip over and that the flushing equipment can actuate the steering knuckle.

[0146] Step 303: Adjust the turntable 5 on the correction device 1 to tilt and raise it according to the tilt direction and tilt angle.

[0147] The steering knuckle is tilted and raised by controlling the turntable 5 on the correction device 1 in a tilting direction and tilting angle. Multiple telescopic rods 4 are provided under the turntable 5. The tilting of the turntable 5 is controlled by controlling the extension and retraction of the telescopic rods 4. When rotation and tilting are required, the turntable 5 must be rotated first, and then tilted.

[0148] Step 304: Based on the tilt and elevation, obtain the top height position of the steering knuckle and the water level information.

[0149] When the steering knuckle tilts and rises, the system acquires the apex height position of the steering knuckle and the water level information. The apex height position refers to the position of the highest point of the steering knuckle. The water level information refers to the height of the water within the detection area. The apex height position is acquired by scanning the steering knuckle using a preset scanning device. The water level information is acquired by a water level sensor within the detection area.

[0150] Step 305: Match the inflation volume from the preset inflation database based on the water level information and the position of the apex height.

[0151] The inflation volume refers to the volume of airbag 2 when inflated. The inflation database can be used to match the water level information with the inflation volume corresponding to the apex height position. The inflation database contains the correspondence between water level information, apex height position, and inflation volume. This database is manually configured and will not be elaborated upon here.

[0152] Step 306: Based on the inflation volume, control the preset inflation airbag 2 to inflate to raise the water level in the detection area, so that the liquid 7 submerges the steering knuckle.

[0153] In this embodiment, the liquid 7 can be a cooling grease or water, preferably water. The inflatable airbag 2 is an airbag used to raise the water level in the detection area. When the airbag 2 is inflated, it raises the water level in the detection area. The inflation of the airbag 2 is controlled based on its inflation volume, thereby raising the water level in the detection area so that the water can submerge the steering knuckle.

[0154] Step 307: After inflation is complete, the flushing force value is matched from the preset flushing database based on the tilt angle and steering knuckle weight value.

[0155] Once inflation is complete, water can then submerge the steering knuckle. The flushing force value is matched from a flushing database based on the tilt angle and steering knuckle weight. The flushing force value refers to the force applied to the steering knuckle. The flushing database contains the correspondence between tilt angle, steering knuckle weight, and flushing force values. This database is manually configured and will not be elaborated upon further.

[0156] Step 308: Determine the location of the flushing force based on the tilt direction and the weight of the steering knuckle.

[0157] The stress point of the flushing device refers to the position of the steering knuckle that is flushed by water when the device flushes it. By analyzing the weight and tilt direction of the steering knuckle, we can determine the tilted and raised position of the steering knuckle, and thus the stress point of the flushing device.

[0158] Step 309: Control the preset flushing device to flush the position of the flushing force value to complete the movement correction.

[0159] A water-flushing device refers to a high-pressure water gun used to flush and correct steering knuckles. By controlling the water-flushing device to apply water pressure to the affected area, the steering knuckle is moved and corrected.

[0160] Reference Figure 4 and Figure 5 The method for detecting the center of gravity of a steering knuckle includes the following steps:

[0161] Step 400: When the detection signal and the placement signal are consistent, obtain the area of ​​the weight force within the detection area.

[0162] When the detection signal matches the placement signal, the weight-bearing area within the detection region is obtained. The weight-bearing area refers to the area where the steering knuckle rests on the detection region and contacts it. Multiple pressure sensors of the same size are installed on the surface of the detection region that contacts the steering knuckle. By knowing the trigger signals of the pressure sensors, the weight-bearing area can be determined.

[0163] Step 401: Determine whether to complete the detection or output an abnormal force signal based on the consistency between the weight-bearing area and the preset reference force-bearing area.

[0164] The reference bearing area refers to the bearing area that the steering knuckle should have when placed flat within the testing area. By judging the consistency between the weight bearing area and the reference bearing area, it can be determined whether the steering knuckle is placed flat within the testing area.

[0165] If the area of ​​the weight-bearing area is the same as the reference area, it means that the steering knuckle is placed flat in the test area, and the test is complete.

[0166] If the area of ​​force application differs from the reference area, it indicates that the steering knuckle is not placed flat within the detection area, and an abnormal force signal must be output. The abnormal force signal indicates that the steering knuckle is not placed flat within the detection area, and it is emitted through a signal transmitter within the detection area.

[0167] Step 402: Based on the abnormal force signal, match the water output force value from the preset water output database according to the weight value of the steering knuckle.

[0168] When an abnormal force signal is issued, it indicates that the steering knuckle needs adjustment. The water pressure value refers to the force of the water discharged when the flushing device 9 adjusts the steering knuckle. The water pressure value corresponding to the steering knuckle weight can be matched through the water pressure database. The water pressure database contains the correspondence between the steering knuckle weight value and the water pressure value. The water pressure database is a manually set database and will not be described in detail here.

[0169] Step 403: Determine the water outlet distance based on the water outlet force value.

[0170] The water outlet distance refers to the height of the water sprayed from the flushing device 9. The corresponding water outlet distance can be matched with a preset distance database based on the water outlet force value. The distance database contains the correspondence between water outlet force values ​​and water outlet distances. This distance database is manually set and will not be elaborated upon here.

[0171] Step 404: Update the vertex height position based on the water outlet distance.

[0172] To prevent water from splashing onto the horizontal surface when the flushing device 9 flushes the steering knuckle, the water level needs to be raised, and the apex height position is updated by adjusting the water discharge distance. A cover is also provided at the top of the detection area to block the water sprayed by the flushing device 9 during flushing.

[0173] Step 405: Update the inflation volume based on the updated vertex height position.

[0174] Because the vertex height position is updated, the inflation volume needs to be updated accordingly.

[0175] Step 406: Based on the updated inflation volume, control the inflation of the airbag 2 to raise the water level in the detection area to the updated apex height position.

[0176] The updated inflation volume is used to control the inflation of airbag 2 to raise the water level in the detection area to the updated peak height position.

[0177] Step 407: Determine the weight distribution of the steering knuckle based on the weight-bearing area and the weight value of the steering knuckle.

[0178] Steering knuckle weight distribution refers to the distribution of weight within the steering knuckle itself. It can be determined by the area of ​​weight distribution and the weight of the steering knuckle.

[0179] Step 408: Determine the current center of gravity and the area of ​​water pressure on the steering knuckle based on the weight distribution of the steering knuckle.

[0180] The current center of gravity of the steering knuckle refers to the center of gravity of the steering knuckle in its current posture. The water-flushing stress area refers to the area where water is flushed by the flushing device 9. The current center of gravity of the steering knuckle and the water-flushing stress area when the steering knuckle is adjusted by flushing can be determined by the weight distribution of the steering knuckle.

[0181] Step 409: Determine the adjustment parameters based on the current center of gravity of the steering knuckle and the preset reference center of gravity of the steering knuckle.

[0182] The reference center of gravity of the steering knuckle refers to its center of gravity when it is in its reference position. Adjustment parameters refer to the direction and distance of adjustment. By comparing the current center of gravity of the steering knuckle with the reference center of gravity, the positional difference of the center of gravity can be determined, and thus the adjustment parameters can be determined.

[0183] Step 410: Based on the adjustment parameters and water pressure value, control the preset flushing device 9 to flush water through the water outlet 8 on the turntable 5 to the flushing force area to correct the current center of gravity of the steering knuckle.

[0184] The flushing device 9 refers to a high-pressure water gun used to flush and adjust the steering knuckle when its center of gravity is abnormal. The flushing device 9 is controlled by adjusting parameters and water pressure values ​​to flush water into the area under stress through the flushing nozzle on the turntable 5 to correct the current center of gravity of the steering knuckle.

[0185] Reference Figure 5 The steering knuckle flushing method also includes the following steps:

[0186] Step 500: Determine the flushing force value based on the steering knuckle weight value.

[0187] The flushing force value refers to the force applied by the flushing equipment 6 when flushing the steering knuckle. A preset flushing database can be used to match the flushing force value to the steering knuckle weight. This database contains the correspondence between steering knuckle weight and flushing force values; it is a manually configured database and will not be elaborated upon here.

[0188] Step 501: Based on the flushing force value, control the preset flushing device 6 to flush the steering knuckle and update the water level information, and control the turntable 5 to rotate one revolution at a preset rotation speed.

[0189] The flushing device 6 refers to a high-pressure water gun used to flush the steering knuckle. The flushing device 6 is controlled to flush the steering knuckle at a specified flushing force, and the water level rises accordingly during flushing, requiring updates to the water level information. During flushing, the turntable 5 is controlled to rotate one revolution at a specified speed to thoroughly flush the steering knuckle. The rotation speed is preset by those skilled in the art and will not be described in detail here.

[0190] Step 5011: Based on the fact that the placement anomaly type is consistent with the rotation placement anomaly and after one rotation, control the flushing device 6 to stop flushing and stop updating the water level information.

[0191] When the placement anomaly type is consistent with the rotation placement anomaly, after one rotation, control the flushing device 6 to stop flushing and stop updating the water level information, and then implement steps 200 to 2022.

[0192] Step 5012: Based on the inconsistency between the placement anomaly type and the rotation placement anomaly, and after one rotation, control the flushing device 6 to continue flushing, and lower the peak height position according to the updated water level information.

[0193] When the placement anomaly type is inconsistent with the rotation placement anomaly, after one rotation, the flushing device 6 is controlled to continue flushing. Since the flushing device 6 is continuously flushing, the water level height information will rise in real time, and the peak height position needs to be lowered.

[0194] Step 50121: Update the inflation volume based on the height position of the descending peak and control the flushing device 6 to stop flushing.

[0195] The inflation volume is updated by controlling the height of the descending peak, and the rinsing device 6 is stopped from rinsing. This prevents water from overflowing into the detection area.

[0196] Reference Figure 5 The method for detecting water level information includes the following steps:

[0197] Step 600: Determine whether the water level information falls within the preset reference height range.

[0198] The reference height range refers to the height range within which the water level should fall within the detection area. By determining whether the water level falls within the reference height range, it is possible to determine whether the current water level needs to be adjusted.

[0199] Step 601: If the water level information exceeds the maximum value of the reference height range, calculate the difference between the water level information and the maximum value of the reference height range, and define the difference as the drainage volume value.

[0200] If the water level exceeds the maximum value of the reference height range, it indicates that the water level needs to be lowered. The difference between the current water level and the maximum value of the reference height range needs to be calculated to determine the drainage volume. The drainage volume refers to the amount of water that needs to be discharged.

[0201] Step 6011: Control the preset drainage device to start according to the drainage volume value, so as to discharge the liquid 7 exceeding the water level into the preset water storage tank.

[0202] A drainage device refers to a water pump used to lower the water level within the detection area. A water storage tank refers to a tank used to store excess liquid 7 within the detection area. The drainage device is controlled to discharge a corresponding amount of water into the water storage tank.

[0203] Step 602: If the water level information does not reach the minimum value of the reference height range, calculate the difference between the water level information and the minimum value of the reference height range, and define the difference as the water replenishment volume value.

[0204] If the water level information does not reach the minimum value of the reference height range, it indicates that the water level in the detection area needs to be raised. The amount of water to be replenished is determined by calculating the difference between the water level information and the minimum value of the reference height range. The amount of water to be replenished refers to the volume of water that needs to be added.

[0205] Step 6021: Based on the water replenishment volume, control the flushing equipment 6 to replenish water to the detection area to raise the water level to within the reference height range.

[0206] By controlling the flushing device 6, water of the corresponding amount is discharged from the water storage tank into the detection area to replenish the water level and raise it to the reference height range.

[0207] The transportation methods after rinsing include:

[0208] Step 700: After rinsing is completed, control the clamping device to clamp and transport the steering knuckle at the preset clamping position and obtain the position of the clamping device.

[0209] The clamping position refers to the clamping location on the steering knuckle. This clamping position is preset by those skilled in the art and will not be elaborated upon here. After the steering knuckle has been flushed, the clamping device is controlled to clamp and transport the steering knuckle at the clamping position and to acquire the clamping device position. The clamping device position refers to the location of the clamping device, which is acquired through a GPS positioning chip located within the clamping device.

[0210] Step 701: Determine whether the position of the clamping device falls within the preset drying area.

[0211] The drying zone refers to the area used for drying the steering knuckle after washing. The drying zone is predetermined by those skilled in the art and will not be elaborated upon here. Whether the blowing device needs to be activated is determined by checking whether the clamping device falls within the drying zone.

[0212] Step 7011: If the position of the clamping device does not fall into the drying area, continue to obtain the position of the clamping device.

[0213] If the clamping device does not fall into the drying area, it means that the clamping device has not yet reached the drying area. There is no need to start the blowing device; just continue to obtain the position of the clamping device.

[0214] Step 7012: If the clamping device falls into the drying area, start the preset blowing device in the drying area and obtain the steering knuckle parameters.

[0215] If the clamping device falls into the drying area, it indicates that the clamping device has reached the drying area. The blowing device within the drying area is then activated, and the steering knuckle parameters are acquired. The blowing device refers to a hot air blower used to dry the steering knuckle. The steering knuckle parameters refer to the dimensions, model, and shape of the steering knuckle. These parameters are obtained by scanning a QR code on the steering knuckle using a pre-set scanner; the content obtained after scanning the QR code corresponds to the steering knuckle parameters.

[0216] Step 70121: Determine the position of the steering hole based on the steering knuckle parameters and the reference placement.

[0217] The position of the steering hole refers to the location of the steering hole on the steering knuckle within the drying area. The position of the steering hole on the steering knuckle can be determined through the steering knuckle parameters, and the placement state of the steering knuckle can be determined through the reference placement state, thus revealing the position of the steering hole.

[0218] Step 70122: Based on the position of the turning hole, control the blowing device to blow dry the turning hole position at a preset blowing temperature.

[0219] The blowing temperature refers to the temperature of the air blown out by the blowing device. The blowing temperature is preset by those skilled in the art and will not be elaborated here. The blowing device is controlled to blow and dry the turning hole position at the preset blowing temperature.

[0220] Step 70123: After drying by blowing air, control the clamping device to clamp the steering knuckle into the alignment device and turn off the blowing device.

[0221] After the air dryer is finished, the control clamping device clamps the steering knuckle into the alignment device and turns off the air blower.

[0222] If the detected pressure value does not exceed the reference pressure value, further testing methods include:

[0223] Step 800: When the detected pressure value exceeds the reference pressure value, determine the location of the abnormal hole according to the detection pin number of the preset detection pin on the alignment device.

[0224] When the detected pressure value exceeds the reference pressure value, it indicates that the detection pin cannot enter the corresponding steering hole. The detection pin refers to the electric push rod on the alignment device used to enter and detect the steering hole. The detection pin has a corresponding detection pin number. When the detection pin cannot enter the steering hole, the location of the abnormal hole can be determined by the detection pin number. The abnormal hole location refers to the location of the steering hole that the detection pin cannot enter.

[0225] Step 801: Output the abnormal hole position signal to the preset signal transceiver terminal according to the abnormal hole position.

[0226] A signal transceiver terminal is a terminal used for transmitting and receiving signals. Signal transceivers are manually configured terminals and will not be elaborated upon here. The abnormal hole position signal is output to the signal transceiver terminal for subsequent verification.

[0227] Step 802: When the detected pressure value does not exceed the reference pressure value, control the preset telescopic device on the detection pin to extend in all directions with a preset extension force value to obtain the gap distance value.

[0228] When the test pressure value does not exceed the reference pressure value, it indicates that the test pin can enter the corresponding steering hole. The telescopic device on the test pin is controlled to extend outwards with a specified extension force to obtain the clearance distance value. The telescopic device refers to the telescopic support rod used to check whether the size of the steering hole is qualified. The extension force value refers to the force exerted by the telescopic device in all directions. The clearance distance value refers to the distance the telescopic device extends outwards.

[0229] Step 803: Determine whether the gap distance value is consistent with the preset reference distance value.

[0230] The reference distance value refers to the distance that the telescopic device should extend. By judging whether the gap distance value is consistent with the reference distance value, we can determine whether the size of the steering hole is up to standard.

[0231] Step 8031: If the gap distance value is consistent with the reference distance value, output the detection completion signal of the steering hole corresponding to the current detection pin number to the signal transceiver terminal.

[0232] If the clearance distance value matches the reference distance value, it indicates that the size of the steering hole is qualified. Then, output the detection completion signal for the steering hole corresponding to the currently detected pin number to the signal transceiver terminal. The detection completion signal indicates that the steering hole of the current steering knuckle is qualified.

[0233] Step 8032: If the gap distance value is inconsistent with the reference distance value, then output a signal indicating that the steering hole is too large to the signal transceiver terminal or output a signal indicating that the steering hole is too small to the signal transceiver terminal according to the relationship between the gap distance value and the reference distance value.

[0234] If the clearance distance value is inconsistent with the reference distance value, the size relationship between the clearance distance value and the reference distance value can be used to determine whether the steering hole is too large or too small.

[0235] When the gap distance value is greater than the reference distance value, it indicates that the steering hole is too large, and a steering hole too large signal needs to be output to the signal transceiver terminal.

[0236] When the gap distance value is less than the reference distance value, it indicates that the steering hole is too small, and a steering hole too small signal needs to be output to the signal transceiver terminal.

[0237] The inspection methods before the steering knuckle is placed into the inspection area include:

[0238] Step 900: Obtain image information of the steering knuckle before detection.

[0239] Pre-inspection image information refers to the image before the steering knuckle is placed in the inspection area. This pre-inspection image information is acquired by taking pictures with a camera.

[0240] Step 901: Determine whether to complete the detection or identify and mark surface defect features based on the consistency between the pre-detection image information and the preset reference image information.

[0241] The reference image information refers to a pre-captured image of the complete steering knuckle. This reference image information is captured in advance by those skilled in the art and will not be elaborated upon here. By assessing the consistency between the pre-inspection image information and the reference image information, it is possible to determine whether the current steering knuckle has any defects.

[0242] If the image information before detection is consistent with the reference image information, it means that there is no defect in the current steering knuckle, and the detection can be completed.

[0243] If the image information before detection is inconsistent with the reference image information, it indicates that there is a defect in the current steering knuckle. The surface defect features are identified and marked by comparing the different features in the image information before detection and the reference image information. Surface defect features refer to the characteristics of defects on the steering knuckle.

[0244] Step 902: Identify the defect type from the preset defect category library based on the surface defect characteristics. The defect types include dent defects and boss defects.

[0245] Defect type refers to the type of surface defect feature. The defect type corresponding to a surface defect feature can be identified through a defect category library. This defect category library is obtained based on deep learning using a neural network model and contains defect types. The defect category library is a manually defined database and will not be elaborated upon here. Defect types include dent defects and boss defects. A dent defect refers to a dent on the surface of the steering knuckle. A boss defect refers to a foreign object on the surface of the steering knuckle.

[0246] Step 903: Based on the boss defect, control the clamping device to clamp the steering knuckle to the preset rework area for rework, and after the rework is completed, control the clamping device to clamp the steering knuckle back to the detection area.

[0247] When a boss defect is detected, the control clamping device clamps the steering knuckle to the repair area for repair. After repair, the control clamping device returns the steering knuckle to the inspection area for further work. The repair area refers to the area used for repairing steering knuckles with boss defects. The repair area is predetermined by those skilled in the art and will not be described in detail here.

[0248] Step 904: Based on the dent defect, control the clamping device to clamp the steering knuckle to the preset recovery area and report a prompt.

[0249] When the defect is a dent, it cannot be repaired. Therefore, the clamping device must be controlled to clamp the steering knuckle to the recovery area and a notification must be sent. The recovery area is the area used to recover steering knuckles that cannot be repaired. The recovery area is predetermined by those skilled in the art and will not be described in detail here.
