[0001] The present invention relates to the field of automobile parts, and in particular to a production method, system and terminal of an actuator. Background Art

[0002] Actuator is a device in the automobile system that receives control signals and converts them into mechanical actions to control various functions of the automobile.

[0003] In the production process of actuators, since actuators are generally plastic parts, they are usually produced by injection molding. After the injection molding is completed, the staff will conduct a final appearance inspection on them. When abnormalities are detected, the staff will make corresponding repairs.

[0004] However, the method of self-detection and repair by staff may lead to failure to detect or incomplete repair if the staff is negligent, thereby reducing the yield rate of the actuator, which needs to be improved. Summary of the invention

[0005] In order to improve the yield rate of an actuator, the present invention provides a production method, system and terminal of an actuator.

[0006] In a first aspect, the present invention provides a method for producing an actuator, which adopts the following technical solution: A method for producing an actuator, comprising: Obtaining a trigger signal of a preset injection molding device; When the trigger signal is consistent with the preset completion signal, the injection molding image information is obtained; Determining current actuator features according to injection molding image information and preset actuator features; When the current actuator feature is inconsistent with the preset reference actuator feature, determining the feature difference position according to the current actuator feature and the reference actuator feature; When the characteristic difference position is consistent with the preset fixing part position, the preset repair device is controlled to repair the characteristic difference position with a preset repair method.

[0007] By adopting the above technical solution, in the injection molding process, the trigger signal of the injection molding device is first obtained. When the signal matches the preset completion signal, the injection molding image information is obtained. It is compared with the actuator characteristics to determine whether the current actuator characteristics meet the standards. If not, the feature difference position is accurately located. Once the difference position is consistent with the position of the fixing part, the repair device is started and processed according to the repair method, thereby improving the yield rate of the actuator.

[0008] Optional repair methods include: Determine the area of ​​the abnormal region based on the injection molding image information, the current actuator characteristics and the preset reference objects; When the area of ​​the abnormal area is lower than the preset reference abnormal area, the amount of repair material is determined according to the area of ​​the abnormal area; Determine feature differences based on current actuator features and benchmark actuator features; Determine the repair path based on the characteristic differences and the amount of repair material used; According to the amount of the repair material used, a preset repair device is controlled to repair the characteristic difference position along the repair path with the preset repair material.

[0009] By adopting the above technical solution, when repairing the actuator, the area of ​​the abnormal region is first determined based on the injection molding image information, the current actuator characteristics and the reference object. If the area is lower than the reference abnormal area, the amount of repair material will be determined based on it. Next, the feature difference is determined based on the current actuator characteristics and the reference actuator characteristics, and the repair path is determined based on the amount of repair material. Finally, the repair device is controlled according to the amount of repair material to repair the feature difference position along the repair path with the repair material, thereby improving the repair efficiency.

[0010] Optionally, the repair method also includes: When the area of ​​the abnormal region is not less than a preset reference abnormal area, the actuator model information of the actuator is obtained; Determine the fixture number based on the actuator model information and feature difference location; Determine the size of the fixture and the surrounding thickness information based on the fixture number; Determine the cutting route based on the surrounding thickness information and the preset cutting temperature value; When the cutting route is consistent with the preset straight cutting route, the cutting speed is determined according to the cutting route, the surrounding thickness information and the cutting temperature value; Control the preset cutting device to heat to the cutting temperature value, and cut along the cutting route at the cutting speed. After cutting, determine the pressing position according to the cutting route and the preset reference incision size; Controlling a preset pressing device to press down and cut the pressing position with a preset pressing force value; When the cutting route is inconsistent with the preset straight line cutting route, the cutting condition is determined according to the cutting route; Determine the selected incision shape according to the incision conditions and the reference incision size; Determine the cutting trimming situation according to the cutting situation and the selected cutting shape; According to the incision trimming situation, the preset cutting device is controlled to perform incision trimming.

[0011] By adopting the above technical solution, when the area of ​​the abnormal region is not less than the reference abnormal area, different processing strategies are adopted for different fixing parts problems. First, obtain the actuator model information, determine the fixing part number, and then clarify its size and surrounding thickness information. If the cutting route is a straight line, determine the cutting speed according to the thickness and temperature, control the cutting device to cut, and then determine the downward pressure position, and the downward pressure device performs downward cutting; if the cutting route is not a straight line, determine the selected incision shape according to the incision situation, and after clarifying the trimming situation, control the cutting equipment to trim, so as to improve the yield rate of the actuator.

[0013] By adopting the above technical solution, after the cutting device completes the cutting operation, the cutting image information will be obtained. When the information contains the preset notch feature, the notch size and position will be determined based on the cutting image information, notch feature and reference. If the notch size is not less than the reference incision size, the incision size will be determined according to the notch size, and the incision position and number of incisions will be further determined in combination with the notch position and cutting feature, and then the incision path will be determined. Finally, the cutting device is controlled to cut along the incision path with the cutting force value. After the cutting is completed, the actuator is repaired by welding using a welding device to improve the overall quality of the product.

[0015] By adopting the above technical solution, when the notch size is lower than the reference incision size, the required expansion size is first calculated based on the notch size and the reference incision size, and then the current notch contour is identified from the contour recognition library based on the cutting image information. Then, the notch cutting step is determined in combination with the current notch contour, the required expansion size and the reference incision contour, and the shearing device is controlled to shear and expand the notch feature according to this step. After the shearing and expansion is completed, the remaining cutting quantity and the remaining cutting position are determined based on the size of the fixing part and the reference incision size, and then the remaining incision path is determined based on the remaining cutting quantity, the remaining cutting position and the reference cutting step.

With the help of this information, combined with the characteristics of the remaining part of the cutting and the reference object, the size of the remaining part is accurately determined. At the same time, the incision size, the notch size and the fixing size are comprehensively considered to calculate the benchmark remaining size. When the remaining part size is higher than the benchmark remaining size, the grinding position is determined based on the incision image information, the remaining part size, the benchmark remaining size and the incision position. Then, according to the grinding position, the remaining part size and the benchmark remaining size, the grinding feed amount is determined, and then the grinding path is obtained. Finally, the preset grinding device is controlled to grind the grinding position along the grinding path with the grinding feed amount to improve the grinding effect.

[0018] Optional welding methods include: After the cutting device cuts along the incision path, the filling size is determined according to the incision path and the preset reserved welding distance; Determine the filling cutting parameters according to the filling size, incision location and number of incisions; Controlling the cutting device to cut the preset replacement supplementary material according to the supplementary material cutting parameters; After cutting, the joint position is determined according to the material-filling cutting parameters and the incision path; Controlling a preset clamping device to clamp the replacement material to the joint position and obtaining joint image information; Determine the welding position according to the joint image information and the preset welding reserved features; The preset welding device is controlled to place preset welding particles into the welding position, and the welding position is welded with preset welding parameters.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The embodiment of the present application discloses a method for producing an actuator.

[0029] Reference Figure 1 and Figure 2 , a method for producing an actuator comprises the following steps: Step 100: Obtain a preset trigger signal of the injection molding device.

[0030] The injection molding device refers to a device used to produce the actuator 1 by injection molding. The trigger signal refers to a signal used to know whether the injection molding device has completed the current injection molding operation. The trigger signal includes a completion signal and a working signal. The completion signal refers to a signal when the injection molding device has completed the current injection molding operation. The working signal refers to a signal when the injection molding device is still performing an injection molding operation. The trigger signal is obtained through a preset signal transceiver on the injection molding device. The completion signal and the working signal are both set in advance by a person skilled in the art and will not be described in detail here.

[0031] Step 101: When a trigger signal is consistent with a preset completion signal, injection molding image information is acquired.

[0032] The injection molding image information refers to the image after the injection molding device completes the injection molding. The injection molding image information is obtained by taking a photo with a camera. When the trigger signal is consistent with the completion signal, it means that the injection molding device has completed the injection molding, and the injection molding image information needs to be obtained for subsequent steps.

[0033] Step 102: Determine current actuator features according to the injection molding image information and preset actuator features.

[0034] The actuator feature refers to the feature of the appearance contour of the actuator 1. The actuator feature is set in advance by a person skilled in the art and will not be described in detail here. The current actuator feature refers to the appearance contour of the actuator 1 currently being injection molded. The actuator features in the injection molding image information can be identified through the feature recognition library, so that the current actuator features can be obtained. The feature recognition library contains the corresponding relationship between the injection molding image information and the actuator features as well as the current actuator features. The feature recognition library is an artificially set database and will not be described in detail here.

[0035] Step 103: When the current actuator feature is inconsistent with the preset reference actuator feature, determine the feature difference position according to the current actuator feature and the reference actuator feature.

[0036] The reference actuator feature refers to the feature that the appearance profile of the actuator 1 should have after it is produced. The reference actuator feature is obtained in advance by a person skilled in the art and will not be described in detail here. The feature difference position refers to the position where there is a difference between the appearance profile of the currently produced actuator 1 and the appearance profile of the reference. By comparing the current actuator feature with the reference actuator feature, the position where the features are different between the two can be obtained, and then the feature difference position can be obtained.

[0037] When the current actuator features are inconsistent with the reference actuator features, the feature difference position needs to be determined for subsequent steps.

[0040] When the characteristic difference position is consistent with the fixing part position, it indicates that the part with the characteristic difference is the fixing part 2 on the actuator 1, and the repair device needs to be controlled to repair the characteristic difference position using a repair method.

[0041] Reference Figure 1 and Figure 3 , the repair method includes the following steps: Step 200: Determine the area of ​​the abnormal region according to the injection molding image information, the current actuator characteristics and the preset reference object.

[0042] A reference object refers to an object used to assist in measuring the area of ​​a difference region at a feature difference position. The position and size of the reference object are set in advance by a person skilled in the art and will not be elaborated here, and the reference object is included in the injection molding image information. The area of ​​an abnormal region refers to the area of ​​a position where a feature difference exists. The injection molding image information, the current actuator feature, and the area of ​​an abnormal region corresponding to the reference object can be matched through a preset area database, which includes the corresponding relationship between the injection molding image information, the current actuator feature, the reference object, and the area of ​​an abnormal region. The area database is an artificially set database and will not be elaborated here.

[0043] Step 201: When the area of ​​the abnormal region is lower than a preset reference abnormal area, determine the amount of repair material according to the area of ​​the abnormal region.

[0044] The reference abnormal area refers to the reference area that can directly repair the characteristic difference position. The reference abnormal area is set in advance by a person skilled in the art and will not be described in detail here. The amount of repair material refers to the amount of material used to repair the characteristic difference position. The amount of repair material corresponding to the area of ​​the abnormal area can be matched through a preset repair database, which contains the corresponding relationship between the area of ​​the abnormal area and the amount of repair material.

[0051] The repair material refers to the material used to repair the characteristic difference position. The specific repair material is set in advance by a person skilled in the art and will not be described in detail here. The control repair device applies the repair material to the characteristic difference position along the repair path according to the corresponding amount of the repair material.

[0052] Reference Figure 1 and Figure 4 , the repair method also includes the following steps: Step 300: When the area of ​​the abnormal region is not less than a preset reference abnormal area, the actuator model information of the actuator 1 is obtained.

[0053] The actuator model information refers to the specification parameters of the actuator 1, which includes the manufacturing structure of the actuator 1. The actuator model information is obtained by scanning the flow barcode on the injection molding device with a preset scanner. The flow barcode is affixed to the injection molding device in advance by a technician in this field and will not be described here. The content obtained by scanning the flow barcode with the scanner corresponds to the actuator model information. When the area of ​​the abnormal area is not lower than the baseline abnormal area, it means that the repair device cannot be directly controlled to repair it, and the actuator model information of actuator 1 must be obtained first for subsequent steps.

[0054] Step 301: Determine the fixture number according to the actuator model information and the characteristic difference position.

[0055] The fixture number refers to the number of the fixture 2 on the actuator 1. In this embodiment, the actuator 1 is provided with three fixtures 2, and each fixture 2 is provided with a corresponding number. By understanding the actuator model information, the manufacturing structure of the actuator 1 can be known, and then by comparing with the characteristic difference position, it can be known which specific fixture 2 on the actuator 1 has an abnormality, and then the fixture number can be obtained.

[0056] Step 302: Determine the size of the fixing part and the surrounding thickness information according to the fixing part number.

[0057] The fixture size refers to the size of the fixture 2 corresponding to the fixture number. The surrounding thickness information refers to the thickness value of the actuator 1 part connected to the fixture 2. The fixture size and surrounding thickness information corresponding to the fixture number can be matched through the preset actuator database, which contains the corresponding relationship between the fixture number, the fixture size and the surrounding thickness information. The actuator database is a manually set database and will not be described here.

[0058] Step 303: Determine a cutting route according to the surrounding thickness information and a preset cutting temperature value.

The cutting device refers to a device used to directly cut the fixing part 2 from the actuator 1. The cutting route refers to the route taken when the cutting device cuts off the fixing part 2. The cutting route corresponding to the surrounding thickness information and the cutting temperature value can be matched through the preset cutting database, which includes the corresponding relationship between the surrounding thickness information, the cutting temperature value and the cutting route. The cutting database is an artificially set database and will not be described in detail here.

[0060] Step 304: When the cutting route is consistent with the preset straight cutting route, the cutting speed is determined according to the cutting route, the surrounding thickness information and the cutting temperature value.

[0061] The straight cutting route refers to the route when the cutting device cuts the fixing member 2 in a straight line. The straight cutting route is set in advance by those skilled in the art and will not be described in detail here. When the cutting route is a straight cutting route, the cutting speed needs to be calculated for subsequent steps. The cutting speed refers to the speed at which the cutting device cuts the fixing member 2. By the algorithm formula v={C e -αT (1 / k m k w k c ) 1 / 3} / h β The cutting speed can be calculated, where v is the cutting speed, h is the surrounding thickness information, T is the cutting temperature value, and k m is the hardness of the material, k w is the degree of wear of the cutting device, k c is the cutting route, C is the comprehensive constant, α is the constant used to measure the influence of cutting temperature on cutting speed, and β is the constant reflecting the influence of material thickness on cutting speed. m , k w , C, α and β are all obtained by prior testing by those skilled in the art and will not be elaborated here.

[0062] Step 305: Control the preset cutting device to heat to the cutting temperature value, and perform cutting along the cutting route at the cutting speed. After cutting, determine the pressing position according to the cutting route and the preset reference incision size.

[0063] The reference incision size refers to the reference size of the incision when the incision is made on the actuator 1. The reference incision size is set in advance by a person skilled in the art and will not be described in detail here. The pressing position refers to the position used to press down and cut the actuator 1. The pressing position corresponding to the cutting route and the reference incision size can be matched through the preset pressing database, which contains the corresponding relationship between the cutting route and the reference incision size and the pressing position. The pressing database is an artificially set database and will not be described in detail here. The cutting device is controlled to heat to the cutting temperature value, and cuts along the cutting route at the cutting speed. After cutting, the pressing position is matched for subsequent steps.

[0064] Step 306: Control the preset pressing device to press down and cut the pressing position with a preset pressing force value.

[0065] The pressing device refers to a device used to press down and cut the actuator 1. By using the pressing device to press down and cut the actuator 1, a cut can be made on the actuator 1, which is convenient for subsequent welding and repair of the actuator 1. The pressing force value refers to the force value used to press down and cut the actuator 1. The pressing force value is set in advance by a person skilled in the art and will not be described here. The pressing device is controlled to press down and cut the pressing position according to the pressing force value.

[0066] Step 307: When the cutting route is inconsistent with the preset straight line cutting route, determine the cutting condition according to the cutting route.

[0067] The incision condition refers to the shape and size of the incision. The incision condition corresponding to the cutting route can be matched through the preset cutting database, which contains the corresponding relationship between the cutting route and the incision condition. The cutting database is a manually set database and will not be described here. When the cutting route is inconsistent with the straight cutting route, it means that the cutting route is an irregular curve and the incision condition needs to be matched for subsequent steps.

[0068] Step 308: Determine the selected incision shape according to the incision condition and the reference incision size.

[0069] Selecting an incision shape means selecting one from a number of incision conditions as the reference shape for subsequent other incisions. The selected incision shape corresponding to the incision condition and the reference incision size can be matched through the preset incision database, which includes the corresponding relationship between the incision condition and the reference incision size and the selected incision shape. The incision database is a manually set database and will not be described in detail here.

[0070] Step 309: Determine the cutting trimming conditions according to the cutting conditions and the selected cutting shape.

[0071] The cut trimming condition refers to the operation of trimming the cuts of other shapes and the uncut parts on the actuator 1 to be consistent with the selected cut shape. The cut condition and the cut trimming condition corresponding to the selected cut shape can be matched through the cut database, which includes the corresponding relationship between the cut condition and the selected cut shape and the cut trimming condition.

[0072] Step 310: Controlling a preset cutting device to perform incision trimming according to the incision trimming situation.

[0073] The cutting device is a device used to directly cut the required cut on the actuator 1. The cutting device is controlled to perform the cut trimming according to the cut trimming condition so as to facilitate subsequent welding repair.

[0074] Reference Figure 1 and Figure 5 , the incision method comprises the following steps: Step 400: After the cutting device performs cutting along the cutting route, cutting image information is obtained.

[0075] The cutting image information refers to the image after the fixing part 2 on the actuator 1 is cut. The cutting image information is obtained by taking a picture with a camera. When the cutting device cuts along the cutting route, the cutting image information needs to be obtained for subsequent steps.

[0076] Step 401: when the cutting image information contains preset notch features, determine the notch size and notch position according to the cutting image information, the notch features and a preset reference object.

[0077] The notch feature refers to the feature presented when a notch appears on the cutting route after the fixing 2 is cut off. The reference object refers to an object used to assist in measuring the size of the notch feature. The position and size of the reference object and the notch feature are all set in advance by those skilled in the art, which will not be elaborated here, and the reference object is included in the cutting image information. The notch size refers to the values ​​of the length, width and height of the notch feature. The notch position refers to the position of the notch feature on the actuator 1. The notch size and notch position corresponding to the cutting image information, notch features and reference objects can be matched through a preset notch database, which includes the corresponding relationship between the cutting image information, notch features, reference objects, notch sizes and notch positions. The notch database is an artificially set database, which will not be elaborated here.

[0078] When the cutting image information contains a notch feature, it means that there is a ready-made notch on the cutting route, which can reduce the number of subsequent cuts accordingly. The notch size and notch position must be determined first for subsequent steps.

[0079] When the cutting image information does not contain a notch feature, it means that there is no notch on the cutting route and the number of subsequent cuts cannot be reduced accordingly. The pressing device can be directly controlled to perform pressing cutting.

[0080] Step 402: When the notch size is not less than a preset reference incision size, determine the incision size according to the notch size.

[0081] The incision size refers to the size of the incision formed when the actuator 1 is subsequently cut. The incision size corresponding to the notch size can be matched through a preset cutting database, which includes the corresponding relationship between the notch size and the incision size. The cutting database is a manually set database and will not be described in detail here.

[0082] When the notch size is not less than the reference incision size, it means that there is no need to make further cuts to the existing notch. The incision size for subsequent cutting can be directly matched with the current notch size for subsequent steps.

[0083] Step 403: Determine the incision position and the number of incisions according to the incision size, the notch position and the preset cutting features.

[0084] Cutting features refer to the features formed after the cutting device cuts along the cutting route. The cutting features are set in advance by those skilled in the art and will not be elaborated here. The incision position refers to the position where the incision appears on the actuator 1 when the cutting device makes an incision. The number of incisions refers to the number of incisions that appear on the actuator 1 when the cutting device makes an incision. The cutting device refers to a device used to directly cut the required incisions on the actuator 1. The incision size, notch position, and the incision position and number of incisions corresponding to the cutting features can be matched through the cutting database, which includes the correspondence between the incision size, notch position, cutting features, incision position, and number of incisions.

[0085] Step 404: Determine the incision path according to the incision size, incision position and incision quantity.

[0086] The incision path refers to the route taken by the cutting device to form an incision on the actuator 1 when the incision device cuts the actuator 1. The incision path corresponding to the incision size, incision position and incision quantity can be matched through the cutting database, which includes the corresponding relationship between the incision size, incision position, incision quantity and incision path.

[0087] Step 405: Control the preset cutting device to perform cutting along the incision path with a preset cutting force value, and after cutting, control the preset welding device to perform welding repair on the actuator 1 with a preset welding method.

[0088] The cutting force value refers to the force value when the cutting device cuts the required incision on the actuator 1. The cutting force value is set in advance by a person skilled in the art and will not be described in detail here. The welding device refers to a device used to weld a new fixing part 2 to the actuator 1 to perform welding repair on the actuator 1. The welding method refers to a method used to weld a new fixing part 2 to the actuator 1 to perform welding repair on the actuator 1.

[0089] The cutting device is controlled to cut the actuator 1 along the incision path with a cutting force value so that a required incision is formed on the actuator 1, and after cutting, the welding device is controlled to perform welding repair on the actuator 1 with a welding method.

[0090] Reference Figure 1 and Figure 6 The incision method further comprises the following steps: Step 500: When the gap size is lower than a preset reference incision size, determine the required expansion size according to the gap size and the reference incision size.

[0091] The required expansion size refers to the size that is required to expand the gap size to make it the same as the reference cut size. The required expansion size can be obtained by calculating the difference between the gap size and the reference cut size. When the gap size is lower than the reference cut size, it means that the existing gap needs to be further cut, and the required expansion size needs to be calculated for subsequent steps.

[0092] Step 501: Identify the current gap contour from a preset contour recognition library according to the cutting image information.

[0093] The current notch contour refers to the outline of the currently existing notch. The current notch contour of the notch feature can be identified in the cutting image information through the contour recognition library. The contour recognition library contains the corresponding relationship between the cutting image information and the current notch contour. The contour recognition library is a manually set database and will not be described in detail here.

[0094] Step 502: Determine the notch cutting step according to the current notch contour, the required expansion size and the preset reference cut contour.

[0095] The reference incision contour refers to the outer contour of the incision when the size of the incision is the reference incision size. The reference incision contour is set in advance by a person skilled in the art and will not be described in detail here. The notch cutting step refers to the operation step of shearing the current notch contour according to the reference incision contour to make it consistent. The current notch contour, the required expansion size and the notch cutting step corresponding to the reference incision contour can be matched through the preset shearing database, which contains the corresponding relationship between the current notch contour, the required expansion size, the reference incision contour and the notch cutting step. The shearing database is a manually set database and will not be described in detail here.

[0096] Step 503: Control the preset shearing device to shear and expand the notch feature in a notch cutting step.

[0097] The shearing device is a device for shearing the notch step by step. The shearing device is controlled to shear and expand the notch feature in the notch cutting step so that the notch size is consistent with the reference notch size.

[0098] Step 504: After the notch feature is sheared and expanded, the remaining cutting quantity and remaining cutting position are determined according to the size of the fixture and the reference cut size.

[0099] The remaining number of cuts refers to the number of remaining cuts required on the actuator 1. The remaining cutting position refers to the position of the remaining cut required on the actuator 1. The remaining number of cuts and the remaining cutting position corresponding to the fixture size and the reference cut size can be matched through the preset cut database, which includes the corresponding relationship between the fixture size, the reference cut size, the remaining number of cuts and the remaining cutting position. The cut database is a manually set database and will not be described in detail here.

[0100] After the notch feature is sheared and expanded, the remaining cutting quantity and remaining cutting position need to be matched for subsequent steps.

[0101] Step 505: Determine the remaining cutting path according to the remaining cutting quantity, the remaining cutting positions and the preset reference cutting steps.

[0102] The reference cutting step refers to the step when the shearing device shears a single remaining cutting position. The reference cutting step is set in advance by a person skilled in the art and will not be described in detail here. The remaining incision path refers to the route when the shearing device shears the number of incisions corresponding to the remaining cutting number. The remaining cutting number, the remaining cutting position and the remaining incision path corresponding to the reference cutting step can be matched through the incision database, which includes the corresponding relationship between the remaining cutting number, the remaining cutting position, the reference cutting step and the remaining incision path.

[0103] Step 506: Control the shearing device to shear the remaining cutting positions along the remaining incision path.

[0104] The shearing device is controlled to shear the remaining cutting positions along the remaining incision path so as to complete the shearing of the incisions corresponding to the remaining number of cuts, thereby facilitating subsequent welding repair.

[0105] Reference Figure 1 and Figure 7 , the grinding method comprises the following steps: Step 600: After the cutting device performs cutting along the cutting path, incision image information is obtained.

[0106] The incision image information refers to the image of the incision after the cutting device cuts the actuator 1 along the incision path so that the required incision is formed on the actuator 1. The incision image information is obtained by taking a photo with a camera. After the cutting device cuts along the incision path, the incision image information needs to be obtained for subsequent steps.

[0107] The feature of the remaining part after cutting refers to the appearance feature of the remaining part of the actuator 1 after the incision is completed. The feature of the remaining part after cutting is set in advance by a person skilled in the art and will not be described in detail here. The size of the remaining part refers to the size of the feature of the remaining part after cutting. The incision image information contains a reference object. The incision image information, the feature of the remaining part after cutting and the size of the remaining part corresponding to the reference object can be matched through a preset size database, which contains the correspondence between the incision image information, the feature of the remaining part after cutting, the reference object and the size of the remaining part. The size database is an artificially set database and will not be described in detail here.

[0108] Step 602: Determine a reference remaining size based on the cut size, the gap size, and the fixing piece size.

[0109] The size of the fixture refers to the size of the fixture 2. The size of the fixture is set in advance by a person skilled in the art and will not be described in detail here. The reference residual size refers to the size that the remaining part size should reach. The reference residual size corresponding to the incision size, the gap size and the fixture size can be matched through the size database, which includes the corresponding relationship between the incision size, the gap size, the fixture size and the reference residual size.

[0110] Step 603: When the remaining portion size is higher than the reference remaining size, the grinding position is determined according to the incision image information, the remaining portion size, the reference remaining size and the incision position.

[0111] The grinding position refers to the position on the incision path of the actuator 1 that needs to be ground after the incision cutting operation is completed. The incision image information, the remaining part size, the reference remaining size and the grinding position corresponding to the incision position can be matched through the preset grinding database, which contains the corresponding relationship between the incision image information, the remaining part size, the reference remaining size, the incision position and the grinding position. The grinding database is a manually set database and will not be described in detail here.

[0112] When the size of the remaining part is higher than the reference remaining size, it means that the size of the cut remaining part feature is too large, which will make it difficult to weld the new fixing part 2 to the actuator 1, and the grinding position needs to be matched for subsequent steps.

[0113] Step 604: Determine the grinding feed amount according to the grinding position, the remaining part size and the reference remaining size.

[0114] The grinding feed refers to the depth of the grinding device when grinding the grinding position. The grinding feed corresponding to different grinding positions can be obtained by calculating the difference between the remaining part size at different grinding positions and the reference remaining size. For example, if there are 2 grinding positions, namely point A and point B, the remaining part size of point A is a, the remaining part size of point B is b, and the reference remaining size is c, then the grinding feed of point A is the difference between a and c, and the grinding feed of point B is the difference between b and c.

[0115] Step 605: Determine a grinding path according to the grinding position and the grinding feed amount.

[0116] The grinding path refers to the route taken by the grinding device when grinding each grinding position. The grinding path corresponding to the grinding position and the grinding feed amount can be matched through the grinding database, which includes the corresponding relationship between the grinding position, the grinding feed amount and the grinding path.

[0117] Step 606: Control the preset grinding device to grind the grinding position along the grinding path with a grinding feed amount.

[0118] The grinding device is controlled to grind the grinding position along the grinding path at a grinding feed rate so as to facilitate subsequent welding of a new fixing member 2 .

[0119] The welding method includes the following steps: Step 700: After the cutting device performs cutting along the incision path, the filling size is determined according to the incision path and the preset reserved welding distance.

[0120] The reserved welding distance refers to the distance reserved between the new fixture 2 before it is welded to the actuator 1. The reserved welding distance is set in advance by a person skilled in the art and will not be elaborated on here. The filling size refers to the size of the protrusion on the new fixture 2 used to insert into the incision on the actuator 1. The filling size corresponding to the incision path and the reserved welding distance can be matched through a preset filling database, which includes the correspondence between the incision path, the reserved welding distance and the filling size. The filling database is an artificially set database and will not be elaborated on here. After the cutting device cuts the fixture 2, the filling size of the new fixture 2 must be matched first for subsequent welding.

[0121] Step 701: Determine the filling cutting parameters according to the filling size, the incision position and the incision quantity.

[0122] The patch cutting parameters refer to the adaptive cutting route planned for the new fixture 2 according to the incision position and number of the actuator 1. The patch cutting parameters corresponding to the patch size, incision position and incision number can be matched through the cutting database, which includes the corresponding relationship between the patch size, incision position, incision number and patch cutting parameters.

[0123] Step 702: Controlling the cutting device to cut the preset replacement supplementary material according to the supplementary material cutting parameters.

[0124] The replacement patch material refers to a new fixture 2 used to replace the cut fixture 2. The cutting device is controlled to cut the replacement patch material with the patch material cutting parameters so that the new fixture 2 can be adapted to the actuator 1.

[0125] Step 703: After cutting, determine the joint position according to the material-filling cutting parameters and the incision path.

[0126] The joining position refers to the position where the replacement patch needs to reach in order to ensure the quality and effect of welding when the replacement patch is welded to the actuator 1. The joining position corresponding to the patch cutting parameters and the incision path can be matched through the preset welding database, which contains the corresponding relationship between the patch cutting parameters and the incision path and the joining position. The welding database is a manually set database and will not be described here. After the replacement patch is cut, the joining position must be determined first for subsequent steps.

[0127] Step 704: Control a preset clamping device to clamp the replacement material to the joining position, and obtain joining image information.

[0128] The clamping device refers to a device used to clamp the replacement material to the joint position. The joint image information refers to the image after the replacement material reaches the joint position. The joint image information is obtained by taking a picture with a camera. The clamping device is controlled to clamp the replacement material to the joint position, and after the replacement material reaches the joint position, the joint image information is obtained for subsequent steps.

[0129] Step 705: Determine the welding position according to the joint image information and the preset welding reserved features.

[0130] The welding reserved feature refers to the feature of the distance formed between the replacement filler and the actuator 1 when the welding distance is reserved in advance. The welding reserved feature is set in advance by a person skilled in the art and will not be described in detail here. The welding position refers to the position of the welding device when welding the replacement filler and the actuator 1. By identifying the welding reserved feature in the joint image information, the position of the welding reserved feature can be known, and the position of the welding reserved feature is the welding position.

[0131] Step 706: Control a preset welding device to place preset welding particles into the welding position, and weld the welding position with preset welding parameters.

[0132] Welding particles refer to particles used to assist in welding the replacement filler and the actuator 1. Welding parameters refer to the power and speed of the welding device during welding. The welding particles and welding parameters are set in advance by those skilled in the art and are not described here. The welding device is controlled to place the welding particles at the welding position and melt the welding particles at the welding position with the welding parameters, so as to weld the replacement filler and the actuator 1.
