[0002] An actuator refers to a device on an all-terrain vehicle that receives an execution instruction and emits a corresponding gear function.

[0003] In the prior art, after the manufacturer completes the production of the actuator, it is necessary to detect the function of the actuator. Generally, the actuator is powered on manually for testing and the current value of the ammeter is observed to compare whether it is normal, and the actuator button is manually pressed to judge the smoothness of the button pressing according to the subjective perception. There are also multiple lights for light-emitting prompts on the actuator. When different buttons are pressed, different lights will emit different colors of light. The accuracy of the lights is judged by manually observing the change of the light color.

[0027] A method, system and terminal for detecting an actuator. The present invention determines whether the actuator is qualified by integrally detecting the product information, emergency stop button and the change of the light color of the actuator, thereby improving the detection efficiency of the actuator.

[0028] Referring to Figure 1 , an embodiment of the present application discloses a method for detecting an actuator, including the following steps: Step 100: Obtain a product image and detection information.

[0029] The product image refers to the image of the actuator, which can be obtained through a camera. The method for obtaining the product image is selected by the staff according to the actual situation and will not be elaborated here. The detection information refers to various information of the actuator, including: software and hardware versions, DTC codes, serial numbers, part numbers, etc. The detection information can be determined by the staff's pre-input.

[0030] Step 101: Determine the product information based on the product image.

[0031] The product information refers to the software and hardware versions, DTC codes, serial numbers, part numbers, etc. when the actuator leaves the factory. The product information can be obtained through image recognition technology. The method for determining the product information is selected by the staff according to the actual situation and will not be elaborated here.

[0032] Step 102: Determine whether the information is qualified based on the product information and the detection information.

[0033] It is determined whether the information of the detected actuator is qualified by comparing whether the content of the detection information and the product information is consistent. The determination method is selected by the staff according to the actual situation and will not be elaborated here.

[0034] Step 103: When the information is qualified, determine the key position based on the product image.

[0036] Step 104: Control the preset pressing device to press according to the key position, and determine the color change based on the product information and the pressing position.

[0037] The pressing device is a device that presses the emergency stop button. The pressing device is selected by the staff according to the actual situation and will not be elaborated here.

The determination method of the working color is common knowledge for those skilled in the art and will not be elaborated here.

[0040] Step 106: Determine whether the actuator is qualified according to the changed color and the working color.

When the working color is inconsistent with the changed color, the actuator is unqualified and the actuator is scrapped.

[0042] Step 107: When the actuator is unqualified, scrap the actuator.

[0043] Unqualified means that the actuator does not meet the factory conditions, and the actuator is scrapped. When it is qualified, it means that the actuator is qualified for the next test.

[0044] When the detected information of the actuator is consistent with the product information, the actuator is positioned and the pressing device is controlled to press, and the color at the button position is observed. If the product information and the color are different, the actuator is scrapped, thereby improving the detection efficiency of the actuator.

[0046] The seal ring feature refers to the position feature of the seal ring in the actuator, which can be obtained by image recognition technology. The determination method of the seal ring feature is selected by the staff according to the actual situation and will not be elaborated here.

[0047] Step 201: Determine the humidification path according to the seal ring feature.

[0048] The humidifying device is used to humidify the seal ring. The humidifying device is selected by the staff according to the actual situation and will not be elaborated here. The humidification path refers to the route along which the humidifying device always sprays water towards the seal ring and circulates along the extension direction of the seal ring when working.

[0052] The working humidity refers to the humidity of the sealing ring when the humidifying device is working. The working humidity is obtained by using a humidity sensor. The method for obtaining the working humidity is selected by the staff according to the actual situation and will not be elaborated here.

[0053] Step 204: Determine the humidity time difference based on the working humidity and the environmental humidity.

[0054] The humidity time difference refers to the time value required for the working humidity to reach the environmental humidity through the humidifying device. The humidity time difference can be obtained by calculating the time difference between the working humidity and the environmental humidity from the time difference data table, which is a data table recording the working humidity at every moment.

[0055] Step 205: Determine the detection current according to the product information, and control the preset detection device to obtain the working current.

[0056] The detection current refers to the rated current that the actuator can withstand. The detection current can be obtained from the current measurement data table, which is a data table recording the detection current corresponding to different product information obtained through experiments in advance. The detection device is a device used to detect the current of the actuator. The detection device is selected by the staff according to the actual situation and will not be elaborated here. The working current is the current of the actuator obtained through the detection device. The working current can be obtained by using the detection device. The method for determining the working current is selected by the staff according to the actual situation and will not be elaborated here.

[0057] Step 206: Determine the difference current based on the working current, the detection current, and the humidity time difference.

[0058] The difference current refers to the maximum value of the difference between the working current and the detection current per unit time. The difference current can be calculated from the difference record table by calculating the current difference between the working current and the detection current at every moment and determining the maximum value from the current differences. The difference record table is a data table recording the working current at every moment and its time.

[0059] Step 207: When the difference current is greater than the preset qualified threshold, scrap the actuator.

[0060] The qualified threshold refers to the maximum safe current value of the actuator during operation. The method for determining the operating current is selected by the staff according to the actual situation and will not be elaborated here. A differential current greater than the qualified threshold indicates that the current value of the operating current during the operation of the actuator is not greater than the detected value.

[0061] When the seal ring feature is recognized, the humidifying device is controlled to humidify the seal ring, thereby changing the humidity of the seal ring and recording the operating current of the actuator in a humid environment, and comparing and calculating the difference with the required maximum current value, so as to scrap the actuator with poor sealing performance.

[0062] Refer to Figure 3 , the seal detection method further includes: Step 208: Obtain the device humidity of the preset absorption device.

[0063] The absorption device refers to a device for secondary sealing. The absorption device can adopt a high molecular water-absorbing resin embedded around the seal ring inside the actuator. The absorption device is selected by the staff according to the actual situation and will not be elaborated here. The device humidity refers to the device humidity of the absorption device. The device humidity can be obtained by using a humidity sensor. The method for obtaining the device humidity is selected by the staff according to the actual situation and will not be elaborated here.

[0064] Step 209: Determine the sealing position of the preset absorption device according to the device humidity.

[0065] The sealing position refers to the position where the seal ring is damaged. The sealing position can be queried for the humidity change value from the seal data table and obtained by comparing the humidity change value with the humidity threshold. The humidity threshold refers to the maximum safe humidity value of the actuator during operation. The seal data table refers to a data table recording the sealing positions corresponding to different device humidities obtained through experiments in advance.

[0066] Step 210: Determine the working distance of the preset inflation device according to the sealing position.

[0067] The inflation device refers to a device for detecting the sealing performance. The inflation device can adopt a circular seal cover connected to the joint of the robotic arm, and the air outlet of the air pump is connected to the circular seal cover. The diameter of the cover opening of the seal cover can be adjusted. After the inflation device completes inflation, it will return to the initial position. The initial position refers to the position where the robotic arm is initially placed. The inflation device is selected by the staff according to the actual situation and will not be elaborated here. The working distance refers to the distance that the inflation device reaches the sealing position, and the working distance can be determined by calculating the distance from the initial position to the sealing position.

[0068] Step 211: Determine the inflation pressure according to the sealing position.

[0069] The inflation pressure refers to the maximum pressure that the sealed position can withstand. The inflation pressure can be obtained by querying the pressure charging data table, which is a data table recording the inflation pressures corresponding to different sealed positions obtained through experiments in advance.

[0070] Step 212: Control the preset inflation device to reach the sealed position according to the working distance, control the inflation device to inflate according to the inflation pressure, and obtain the working pressure.

[0071] The working pressure refers to the pressure generated by the inflation device on the sealed position. The working pressure can be obtained by using a pressure sensor for detection. The method for obtaining the working pressure is selected by the staff according to the actual situation and will not be elaborated here.

[0072] Step 213: Determine the pressure difference according to the inflation pressure and the working pressure.

[0073] The pressure difference refers to the difference between the inflation pressure and the working pressure, which can be obtained by calculating the difference between the working pressure and the inflation pressure. The method for determining the pressure difference is common knowledge in the field and will not be elaborated here.

[0074] Step 214: Determine the damaged position according to the pressure value difference.

[0075] The damaged position refers to the position where the absorption device on the actuator leaks air. The damaged position can be determined by first looking at the inflation pressure in the calculation of the pressure difference and then looking at the position number of the absorption device corresponding to the inflation pressure according to the pressure charging data table.

[0076] Step 215: Control the preset alarm device to give an alarm according to the damaged position.

[0077] The alarm device refers to a device that gives an alarm and produces a red light. The alarm device is selected by the staff according to the actual situation and will not be elaborated here.

[0078] When the humidity of the device is detected, control the inflation device to inflate at the sealed position and compare the working pressure and the inflation pressure. If they are not equal, make the alarm device give an alarm, so that the position where the sealing ring on the actuator is damaged can be located and an alarm can be given.

[0079] Refer to Figure 4 For the seal detection method, it further includes: Step 216: Determine the external shape angle according to the product image.

[0080] The external shape angle refers to each angle of the external shape of the actuator. The external shape angle can be obtained by using angle detection technology. The method for determining the external shape angle is selected by the staff according to the actual situation and will not be elaborated here.

[0081] Step 217: Determine the changing position according to the external shape angle.

[0082] The change position refers to the position where the shape angle changes. The change position can be determined by analyzing the shape angle. The method for determining the change position is common knowledge among those skilled in the art and will not be elaborated here.

[0083] Step 218: Determine the change area according to the sealing position and the change position.

[0084] The changing area refers to the area where the sealing cover does not leave the sealing position and reaches the maximum cover stability. The continuous part of the changing position can be used as a surface frame to select all the surfaces on the actuator surface, and then the surface range including the sealing position is used as the surface contour according to the positional relationship between the sealing position and all the surfaces, and the closest point of the surface contour to the sealing position is determined, and then the circle with the sealing position as the closest point to the center and the sealing position as the radius is used as the changing area. The method for determining the changing area is common knowledge among people in this field and will not be elaborated here.

[0085] Step 219: Determine the changed diameter of the inflatable device according to the changed area.

[0086] The change diameter refers to the diameter of the inflatable device that needs to be changed according to the change area, and the change diameter is further determined by calculating the change area of ​​the maximum diameter of the change area.

[0087] Step 220: Control the inflatable device to change its diameter according to the changed diameter, and control the inflatable device to cover the changed area.

[0088] The diameter of the inflatable device is changed by changing the diameter control, so that the diameter of the inflatable device changes so that the changed area can be covered.

[0089] Step 221: Control the inflation device to inflate according to the inflation pressure and obtain the working pressure.

[0090] When the diameter of the inflator is too large, it is easy for the sealing cover to cover both the curved and flat parts on the actuator surface when the sealing cover is in the sealing position, thereby causing the cover opening of the sealing cover to separate from the actuator surface. The diameter of the cover opening of the sealing cover can be adjusted to prevent the inflator from separating from the changing area and causing air leakage. When the diameter of the inflator is too small, it is easy for the cover opening of the sealing cover to have too small a contact area with the actuator surface, thereby causing the friction between the cover opening of the sealing cover and the actuator surface to be small, thereby causing the sealing cover to slip when it is in the sealing position. The slippage of the inflator can be reduced by adjusting the diameter of the cover opening of the sealing cover so that the diameter of the cover opening of the sealing cover reaches the nearest point of the outer contour of the area.

[0091] Change the diameter of the inflation device according to the detected change area, so that the inflation device can cover the change area and inflate, obtain the inflation pressure, thereby detecting the complex change angle of the product image, so that the inflation device can reach the complex position more conveniently, and then improve the detection efficiency of the actuator.

[0092] Refer to Figure 5 , the seal detection method further includes: Step 222: Determine the covering position according to the seal position and the product image.

[0093] The buffer device refers to a rotatable buffer pad with good sealing performance on the seal cover that contacts the actuator.

The covering position refers to the position of the buffer device on the surface of the actuator when the seal cover covers the seal position, which can be obtained through image recognition technology. The method for determining the covering position is selected by the staff according to the actual situation and will not be elaborated here.

[0094] Step 223: Determine the buffer angle according to the covering position and the product image.

[0095] The buffer angle refers to the angle that the buffer device needs to change to fit the covering position on the actuator. The method for determining the buffer angle can be determined through image recognition technology. The method for determining the buffer angle is well-known common sense to those skilled in the art and will not be elaborated here.

[0096] Step 224: Control the angle of the buffer device to change according to the buffer angle, and control the preset inflation device to cover the seal position.

[0097] Control the angle change of the buffer device on the inflation device through the determined buffer angle so that the inflation device can seamlessly cover the seal position when reaching the seal position.

[0098] Step 225: Determine the suction pressure of the inflation device according to the seal position.

[0099] The suction pressure refers to the maximum negative pressure that the seal position can withstand. The suction pressure can be obtained by querying the suction pressure data table. The suction pressure data table refers to the table that records the suction pressures determined in advance through experiments for different seal positions.

[0100] Step 226: Control the inflation device to suck air according to the suction pressure and obtain the working air pressure.

[0101] The working air pressure refers to the air pressure value generated when the inflation device sucks air at the seal position. The working air pressure can be detected by using a pressure sensor. The method for obtaining the working air pressure is selected by the staff according to the actual situation and will not be elaborated here.

[0102] Step 227: Determine the air pressure difference according to the working air pressure and the suction pressure.

[0103] The pressure difference refers to the difference between the suction pressure and the working air pressure, which can be obtained by calculating the difference between the working air pressure and the suction pressure. The method for determining the air pressure difference is common knowledge to those skilled in the art and will not be elaborated here.

[0104] Step 228: Determine the damaged position according to the air pressure difference.

[0105] When it is detected that the covering device cannot reach the sealing position, change the buffer angle according to the image so that the inflating device can reach the sealing position and perform suction to obtain the working air pressure, preventing air leakage caused by the non - fitting of the inflating device to the plane, which may lead to incorrect detection results.

[0106] Refer to Figure 6 , the repair method further includes: Step 300: Determine the heating distance according to the sealing position.

[0107] The heating device refers to the device used to heat the damaged position of the sealing ring.

The heating position refers to the position of the heating device when it is not working. The method for obtaining the heating distance is selected by the staff according to the actual situation and will not be elaborated here.

[0108] Step 301: Control the preset heating device to reach the sealing position and heat according to the heating distance, and determine the force direction according to the sealing position.

The force direction refers to the direction of pressing the actuator. The force directions generally appear in pairs, and the side with the upward direction is taken as the upper force direction, and the side with the downward direction is taken as the lower force direction. The force direction can be obtained by querying from the direction data table, and the direction data table refers to the data table recording the force directions corresponding to different sealing positions obtained through experiments in advance.

[0110] Step 302: Determine the upper analysis area and the lower analysis area according to the product image.

[0111] The upper analysis area and the lower analysis area refer to the areas used for force analysis. The area above the sealing ring in the product image is taken as the upper analysis area, and the area below the sealing ring in the product image is taken as the lower analysis area.

[0112] Step 303: Determine the force range according to the force direction and the sealing position.

[0113] The force-bearing range refers to the angular range on the surface of the actuator where pressure can be exerted in the force-bearing direction. The force-bearing range is determined according to the force-bearing direction. When the force-bearing direction is A, the force-bearing range is from (A + 90) degrees to (A + 270) degrees. The force-bearing range corresponds one-to-one with the force-bearing direction, that is, the upper force-bearing direction corresponds to the upper force-bearing range, and the lower force-bearing direction corresponds to the lower force-bearing range.

[0114] Step 304: Determine the upper force-bearing point and the lower force-bearing point according to the force-bearing range, the sealing position, the upper analysis area, and the lower analysis area.

[0115] The force-bearing range, the force-bearing direction, and the analysis area correspond one-to-one. The upper force-bearing point and the lower force-bearing point refer to the positions where the pressing device presses on the upper analysis area and the lower analysis area respectively. The upper force-bearing point can be found in the upper analysis area to find the upper force-bearing area with a surface angle within the lower force-bearing range, and the point closest to the sealing position within the upper force-bearing area is taken as the upper force-bearing point. The lower force-bearing point can be found in the lower analysis area to find the lower force-bearing area with a surface angle within the upper force-bearing range, and the point closest to the sealing position within the lower force-bearing area is taken as the upper force-bearing point.

[0116] Step 305: Determine the regional pressure according to the upper force-bearing point, the lower force-bearing point, and the product information.

[0117] The regional pressure refers to the maximum pressure that the upper force-bearing point and the lower force-bearing point on the actuator can accept for pressing. The regional pressure can be obtained by querying from the pressure data table. The pressure data table refers to the data table that records the regional pressures corresponding to different upper force-bearing points, lower force-bearing points, and product information obtained through experiments in advance.

[0118] Step 306: Control the preset pressing device to press the upper force-bearing point and the lower force-bearing point according to the regional pressure, and obtain the sealing temperature at the sealing position.

[0119] The sealing temperature refers to the temperature at the sealing position after the heating device heats the sealing device. The sealing temperature can be obtained through a temperature sensor. The method for obtaining the sealing temperature is selected by the staff according to the actual situation and will not be elaborated here.

[0120] Step 307: When the sealing temperature is less than the preset sealing threshold, control the preset pressing device to disengage from the upper force-bearing point and the lower force-bearing point.

[0121] The sealing threshold refers to the highest temperature at which the sealing ring solidifies. The sealing threshold is selected by the staff according to the actual situation and will not be elaborated here.

[0122] When the sealing position is detected, control the heating device to heat, and perform a force analysis on the upper and lower areas of the sealing position, control the pressing device to press, so as to close the sealing ring, restore the sealing performance of the sealing ring, and thus meet the factory standards.

[0123] Refer to Figure 7, the repair method further includes: Step 308: Determine the lost force point based on the upper force point and the lower force point.

[0124] The lost force point refers to the force point that cannot be found in the allowable analysis area. When there is no upper force point, the upper force point is the lost force point. When there is no lower force point, the lower force point is the lost force point.

[0125] Step 309: Determine the lost force direction based on the lost force point and the force direction.

[0126] The lost force direction refers to the force direction corresponding to the lost force point. When the lost force point is the upper force point, the lost force direction is the lower force direction. When the lost force point is the lower force point, the lost force direction is the upper force direction.

[0127] Step 310: Determine the pressing position based on the lost force direction and the product image.

[0128] The pressing position refers to the position where the entire pressing device presses on the product image after the lost force point exists. The pressing position can adopt the highest point of the actuator in the lost force direction. The method for determining the pressing position is selected by the staff according to the actual situation and will not be elaborated here.

[0129] Step 311: Control the pressing device to press according to the regional pressure based on the pressing position.

[0130] When the upper and lower force points cannot be detected through force analysis, determine the lost force direction and control the pressing device to press on the overall pressing position determined by the product image, so that when there is no paired force, the entire pressing actuator can be used to assist in the repair of the sealing ring.

[0131] Refer to Figure 8 , the repair method further includes: Step 312: Determine the working orientation of the preset blowing device based on the sealing position.

[0132] The blowing device is a device that accelerates the cooling of the sealing position. The blowing device is selected by the staff according to the actual situation and will not be elaborated here. The working orientation refers to the angle that the blowing device needs to rotate to blow air towards the sealing position. The method for determining the working orientation is common knowledge for those skilled in the art and will not be elaborated here.

[0133] Step 313: Determine the blowing distance of the preset blowing device based on the sealing position.

[0134] The blowing distance refers to the distance between the blowing device and the sealing position. The blowing distance can be obtained by querying the wind distance data table. The wind distance data table is a data table that records the blowing distances corresponding to different sealing positions through prior experiments.

[0135] Step 314: Determine the working wind speed according to the sealing temperature and the blowing distance.

[0136] The working wind speed refers to the minimum wind speed at which, under the blowing distance, the blowing device blows air to reduce the sealing temperature. The working wind speed can be obtained by querying the wind speed data table, which refers to the table recording the working wind speeds corresponding to different sealing temperatures and blowing distances determined in advance through experiments.

[0137] Step 315: Control the rotation of the preset blowing device according to the working orientation, and control the preset blowing device to blow air according to the working wind speed.

[0138] The blowing device refers to the device used to reduce the temperature of the sealing ring. The reading device is selected by the staff according to the actual situation and will not be elaborated here.

[0139] Determine the orientation of the blowing device towards the sealing position according to the sealing position, and control the blowing device to reach above the sealing position to blow air, so as to cool down the sealing position, and further accelerate the solidification speed of the sealing ring at the sealing position.
