Technical Field

[0001] The present invention relates to the field of automotive parts, and particularly to a detection method based on an automotive actuator and an intelligent terminal. Background Art

[0002] An automotive actuator is an important part of an automotive electronic control system. It receives instructions sent by an electronic control unit and converts them into specific mechanical actions or physical quantity changes, thereby realizing the control of various functions of the vehicle.

[0003] Currently, when manufacturing an actuator, it is usually manufactured by injection molding. Molten plastic is injected into the mold cavity, and after cooling and solidifying, the actuator housing and other components are demolded. Since the actuator may be damaged by external factors, multiple reinforcing ribs are provided inside the actuator to reduce damage to the actuator.

[0004] However, the actuator has multiple usage positions in the vehicle, so the positions where the actuator is likely to be damaged are also different. In actual production, if the reinforcing ribs are set with a unified specification, it is difficult to provide precise and effective protection for the vulnerable parts of the actuator in different usage scenarios, and there is room for improvement.

[0020] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0021] Refer to Figure 1 and Figure 2 An embodiment of the present application discloses a detection method based on an automotive actuator, including the following steps: Step 100: Obtain the usage location information of the actuator 1.

[0022] The usage location information refers to the specific usage location on the vehicle where the actuator 1 is installed. The usage location information is obtained by pre-input by the staff and will not be elaborated here.

[0023] Step 101: Determine the actuator model according to the usage location information.

[0024] The actuator model is the specific identification code of the actuator 1, which is used to distinguish different types, specifications, functions, and characteristics of the actuator 1. Through a preset model database, the actuator model corresponding to the usage location information can be matched, which contains the corresponding relationship between the usage location information and the actuator model. The model database is a manually set database and will not be elaborated here.

[0025] Step 102: Match the daily damage location and the reference rib position from a preset damage database according to the actuator model.

[0026] The daily damage location refers to the part of the actuator 1 corresponding to the actuator model that is most likely to be damaged when a damage occurs. The reference rib position refers to the position of the rib on the actuator 1 of this model.

The damage database is a manually set database and will not be elaborated here.

[0027] Step 103: Determine the additional position and the additional quantity according to the daily damage location and the reference rib position.

[0028] The additional position refers to the position where the rib needs to be added to the actuator 1 of this model. The additional quantity refers to the number of ribs that need to be added to the actuator 1 of this model. Through a preset rib database, the additional position and the additional quantity corresponding to the daily damage location and the reference rib position can be matched, which contains the corresponding relationship between the daily damage location, the reference rib position, the additional position, and the additional quantity. The rib database is a manually set database and will not be elaborated here.

[0029] Step 104: Determine the placement structure based on the additional position, the number of additional ribs, and the position of the reference reinforcing rib.

[0030] The placement structure refers to the structural form with a specific contour formed after the operation of adding reinforcing ribs. Through the reinforcing rib database, the placement structure corresponding to the additional position, the number of additional ribs, and the position of the reference reinforcing rib can be matched, which includes the corresponding relationship between the additional position, the number of additional ribs, the position of the reference reinforcing rib, and the placement structure.

[0031] Step 105: Based on the placement structure, control the preset 3D printing device to perform printing adjustment. After the adjustment is completed, control the 3D printing device to produce the actuator 1 corresponding to the actuator model. After the printing production is completed, send the actuator 1 to the preset final assembly area for assembly, and perform steering detection using the preset steering detection method.

[0032] The 3D printing device refers to the device used for printing and producing the housing of the actuator 1. The final assembly area refers to the area used for assembling the internal components of the printed actuator. The final assembly area is set in advance by those skilled in the art and will not be elaborated here. The steering detection method refers to the method used for detecting the forward and reverse rotation of the actuator. The specific steering detection method will be described in detail in subsequent steps 200 to 204 and will not be elaborated here.

[0033] Before controlling the 3D printing device to produce the actuator 1 corresponding to the actuator model, first input the placement structure into the 3D printing device for printing adjustment. After the adjustment is completed, control the 3D printing device to produce the actuator 1 corresponding to the actuator model, thereby completing the production of the actuator 1. After the printing production is completed, send the actuator 1 to the final assembly area for assembly. After the assembly is completed, perform steering detection using the steering detection method.

[0034] The steering detection method includes: Step 200: After the actuator 1 is finally assembled, control the preset steering detection device to perform forward rotation wiring in the preset forward rotation detection mode, and control the actuator 1 to rotate to obtain forward rotation detection information.

[0035] The steering detection device refers to the device used for detecting the forward and reverse rotation of the actuator 1. A motor is installed on the actuator 1, and the motor includes a positive electrode and a negative electrode. The steering detection device also has a positive electrode and a negative electrode for connecting the positive and negative electrodes of the actuator.

[0036] The forward rotation detection method refers to the method used to detect the forward rotation of the actuator 1. In this embodiment, the forward rotation detection method is: connecting the positive pole of the steering detection device to the positive pole of the actuator, and connecting the negative pole of the steering detection device to the negative pole of the actuator. The forward rotation detection information refers to the detection result after detecting the forward rotation of the actuator 1. The forward rotation detection information is obtained by retrieving a preset detection terminal. After the steering detection device detects the forward rotation of the actuator 1, the forward rotation detection information will be input into the detection terminal for subsequent retrieval. The detection terminal refers to the terminal used to record and save various detection information of the actuator 1. The detection terminal is preset by those skilled in the art and will not be elaborated here.

[0037] After the actuator 1 is finally assembled, control the steering detection device to perform forward rotation wiring on the actuator 1 in the forward rotation detection method, so as to control the actuator 1 to rotate and finally obtain the forward rotation detection information.

[0038] Step 201: When the forward rotation detection information is not the preset forward rotation, report a forward rotation abnormality prompt.

[0039] The forward rotation refers to the operating state when the actuator 1 rotates forward. The forward rotation is preset by those skilled in the art and will not be elaborated here.

[0040] When the forward rotation detection information is not the forward rotation, it indicates that there is an abnormality in the forward rotation of the actuator 1, and a forward rotation abnormality prompt needs to be reported.

[0041] Step 202: When the forward rotation detection information is the preset forward rotation, control the preset steering detection device to perform reverse rotation wiring in the preset reverse rotation detection method, and control the actuator 1 to rotate to obtain the reverse rotation detection information.

[0042] The reverse rotation detection method refers to the method used to detect the reverse rotation of the actuator 1. In this embodiment, the reverse rotation detection method is: connecting the positive pole of the steering detection device to the negative pole of the actuator, and connecting the negative pole of the steering detection device to the positive pole of the actuator. The reverse rotation detection information refers to the detection result after detecting the reverse rotation of the actuator 1. The reverse rotation detection information is obtained by retrieving the detection terminal. After the steering detection device detects the reverse rotation of the actuator 1, the reverse rotation detection information will be input into the detection terminal for subsequent retrieval.

[0043] When the forward rotation detection information is the forward rotation, it indicates that there is no abnormality in the forward rotation of the actuator 1. It is necessary to control the steering detection device to perform reverse rotation wiring on the actuator 1 in the reverse rotation detection method, so as to control the actuator 1 to rotate and finally obtain the reverse rotation detection information.

[0044] Step 203: When the reverse rotation detection information is not the preset reverse rotation, report a reverse rotation abnormality prompt.

[0045] Reverse rotation refers to the operating state when the actuator 1 rotates in reverse. The reverse rotation is preset by those skilled in the art and will not be elaborated here.

[0046] When the reverse detection information is not the reverse rotation, it indicates that there is an abnormality in the reverse rotation of the actuator 1, and a reverse abnormality prompt needs to be reported.

[0047] Step 204: Based on the reverse detection information being the preset reverse rotation, complete the steering detection.

[0048] When the reverse detection information is the reverse rotation, it indicates that there is no abnormality in the forward and reverse rotations of the actuator 1, and the steering detection can be completed.

[0049] When there is no steering abnormality in the actuator 1, it will control the actuator 1 to complete a 360° steering operation to check whether there is a jamming phenomenon when the actuator 1 makes a 360° turnover.

[0050] When a jamming phenomenon occurs, by knowing the angle value that has been rotated when the jam occurs, and combining the structure of the actuator 1 and the rotation direction, the cause of the jam can be known, and then reported so that the staff can conduct specific inspections.

[0051] Refer to Figure 1 and Figure 3 , the attitude detection method includes the following steps: Step 300: After production is completed, control the preset closing device to perform extrusion pre-closing on the actuator 1 and obtain the closing image information.

[0052] The closing device refers to the robotic arm used to perform extrusion pre-closing on the produced actuator 1. The closing image information refers to the image of the actuator 1 after pre-closing. The closing image information is obtained by taking a photo with a camera.

[0053] In this embodiment, after the actuator 1 is produced by printing, it presents a state where the left half and the right half are separated. At this time, the two separated parts need to be closed and assembled to form a complete and usable actuator 1. And there are holes on one of the halves of the components of the actuator 1, and the half with holes is defined as the part with holes, and the other half of the components is defined as the part without holes. The reinforcing ribs mentioned in the previous steps are located on the part without holes. And what is produced in this embodiment is the housing of the actuator 1.

[0054] After the printing production of the actuator 1 is completed, it is necessary to first control the closing device to perform extrusion pre-closing on the actuator 1, and then obtain the closing image information for subsequent steps.

[0055] Step 301: Determine the hole position according to the closing image information and the preset hole characteristics.

[0056] The hole feature refers to the appearance contour feature of the holes existing on the actuator 1. The hole feature is preset by those skilled in the art and will not be elaborated here. The hole position refers to the exact position of a specific half part (left half part or right half part) where the hole is located on the actuator 1.

[0057] Step 302: Determine the reference placement posture according to the hole position.

[0058] The reference placement posture refers to the specific posture that the actuator 1 must be placed in before carrying out subsequent detection work on the actuator 1. The reference placement posture corresponding to the hole position can be matched through a preset posture database, which contains the corresponding relationship between the hole position and the reference placement posture. The posture database is a database set by humans and will not be elaborated here.

[0059] Step 303: Determine the current placement posture according to the closed image information and the preset actuator features.

[0060] The actuator features refer to the appearance contour features of the actuator 1. The actuator features are preset by those skilled in the art and will not be elaborated here. The current placement posture refers to the posture that the actuator 1 is currently placed in. The current placement posture corresponding to the closed image information and the actuator features can be matched through the posture database, which contains the corresponding relationship between the closed image information, the actuator features, and the current placement posture.

[0061] Step 304: When the current placement posture is inconsistent with the reference placement posture, determine the posture adjustment parameters according to the current placement posture and the reference placement posture.

[0062] The posture adjustment parameters refer to the angles and directions when adjusting the posture of the actuator 1. The posture adjustment parameters corresponding to the current placement posture and the reference placement posture can be matched through the posture database, which contains the corresponding relationship between the current placement posture, the reference placement posture, and the posture adjustment parameters.

[0063] When the current placement posture is inconsistent with the reference placement posture, it indicates that when carrying out subsequent detections, the posture of the actuator 1 needs to be adjusted. It is necessary to first match the posture adjustment parameters for subsequent steps.

[0064] Step 305: Control the closing device to adjust the posture of the actuator 1 according to the posture adjustment parameters, and after completing the posture adjustment, detect the reinforcing ribs by a preset internal detection method.

[0065] The internal detection method refers to the method used to detect the reinforcing ribs inside the actuator 1. The specific internal detection method will be described in detail in subsequent steps 400 to 408 and will not be elaborated here.

[0066] Control the closing device to adjust the attitude of actuator 1 according to the attitude adjustment parameters. After the attitude adjustment is completed, detect the reinforcing ribs by the internal detection method.

[0067] The internal detection method includes the following steps: Step 400: Determine the housing material information, reference wall thickness value, and reference water injection volume of actuator 1 according to the actuator model.

[0068] The housing material information refers to the material used for the housing of the two halves of actuator 1 currently formed by printing. The reference wall thickness value refers to the thickness value of the housing of actuator 1. The reference water injection volume refers to the water volume value required to be injected when performing the water injection detection on this actuator 1. The housing material information, reference wall thickness value, and reference water injection volume corresponding to the actuator model can be retrieved through the preset actuator database, which contains the correspondence between the actuator model, housing material information, reference wall thickness value, and reference water injection volume. The actuator database is a manually set database and will not be elaborated here.

[0069] Step 401: Determine the current hole position according to the reference placement attitude and the actuator model.

[0070] The current hole position refers to the position where the hole on actuator 1 is currently located. The current hole position corresponding to the reference placement attitude and the actuator model can be matched through the actuator database, which contains the correspondence between the reference placement attitude, actuator model, and current hole position.

[0071] Step 402: Control the preset water injection detection device to align with the current hole position, and inject water with corresponding parameters into actuator 1 according to the reference water injection volume and the preset detection temperature value.

[0072] The water injection detection device refers to the device used to perform the water injection detection on actuator 1. The detection temperature value refers to the temperature value of the water injected when performing the water injection detection on actuator 1. The detection temperature value is set in advance by those skilled in the art and will not be elaborated here.

[0073] Control the water injection detection device to align with the current hole position, and inject water with corresponding parameters into actuator 1 according to the reference water injection volume and the detection temperature value for subsequent detection.

[0074] For example, when the water injection detection device injects water at the hole position, it will block the hole position to prevent the injected water from flowing out. After the injection is completed, the water in the part with holes needs to be transferred to the part without holes through subsequent steps.

[0075] Step 403: Determine the required flipping speed according to the reference water injection volume.

[0076] The demand flipping speed refers to the speed that the actuator 1 needs to reach when performing a 180° flip. When the actuator 1 performs a 180° flip, since the flipping speed is very fast, the injected water will temporarily stay at the perforated part under the action of centrifugal force. After the flip is completed, the injected water will fall simultaneously, so that all the water can quickly contact each part of the inner wall of the non-perforated part.

[0077] The demand flipping speed corresponding to the reference water injection volume can be matched through a preset flipping database, which contains the corresponding relationship between the reference water injection volume and the demand flipping speed. The flipping database is a database set by humans and will not be elaborated here.

[0078] Step 404: Determine the reference temperature value according to the housing material information, the reference wall thickness value, the detected temperature value, and the preset waiting duration.

[0079] The waiting duration refers to the duration that the actuator 1 needs to wait after flipping. The waiting duration is set in advance by those skilled in the art and will not be elaborated here. The reference temperature value refers to the temperature value that the non-perforated part of the actuator 1 should reach. The reference temperature value corresponding to the housing material information, the reference wall thickness value, the detected temperature value, and the waiting duration can be matched through a preset temperature database, which contains the corresponding relationship between the housing material information, the reference wall thickness value, the detected temperature value, the waiting duration, and the reference temperature value. The temperature database is a database set by humans and will not be elaborated here.

[0080] Step 405: When the demand flipping speed does not exceed the preset reference flipping speed, control the closing device to flip at the demand flipping speed, and after the waiting duration, obtain the thermal energy image information and the surface temperature value of the actuator 1.

[0081] The reference flipping speed refers to the maximum flipping speed that the closing device can support. The reference flipping speed is set in advance by those skilled in the art and will not be elaborated here. The thermal energy image information refers to the thermal energy image on the surface of the actuator 1. The thermal energy image information is obtained by taking a photo with a preset thermal energy camera. The surface temperature value refers to the temperature value on the surface of the non-perforated part of the actuator 1. The surface temperature value is obtained by measuring with a temperature sensor.

[0082] When the demand flipping speed does not exceed the reference flipping speed, it means that the closing device can flip the actuator 1. It is necessary to control the closing device to flip the actuator 1 at the demand flipping speed, and after the waiting duration, obtain the thermal energy image information and the surface temperature value of the actuator 1 for subsequent steps.
