[0002] The car USB interface is a universal serial bus (USB) interface installed inside the car and is mainly used to connect various external devices to the car's electronic system.

[0014] By adopting the above technical solution, the abnormality of the automobile USB interface can be known by understanding the consistency between the detection weight value and the reference weight value. When an abnormality occurs, the cause of the abnormality can be known by understanding the inclusion of the detection image information and the burr feature. And when burrs are included, the removal method can be known by understanding the burr position and burr range, and then the burrs can be removed, thereby improving the yield rate of the automobile USB interface.

And when the cut-out lighting image contains light transmission characteristics, the path thickness change can be known by understanding the path light transmission intensity value, and then the excess material cutting method can be known. In this way, the interface is opened to improve the yield rate of the automotive USB interface.

[0042] Optional methods of removing excess material include:

[0043] When the path thickness change is consistent with the preset reference thickness change, the remaining thickness value is matched from the material database according to the path light transmittance value, the lighting intensity value and the interface material information;

[0057] By adopting the above technical scheme, when the heating device heats the burr feature or the heating range, the smoke direction is known through the current wind direction information and the interface material information, and then the suction position and the suction direction can be known. Then, by understanding the relationship between the heating temperature value and the removal temperature value, the suction temperature value is known, and then the suction force value is known.

[0065] By adopting the above technical solution, when the heating device heats the burr feature or the heating range, the collection device is controlled to collect the waste by understanding the heating position. Then, by understanding the inclusion between the heating image information and the foreign matter feature, the adhesion of the foreign matter on the material outside the interface is known. When adhesion exists, by understanding the position of the foreign matter, the clamping device is controlled to crush the foreign matter feature for subsequent grinding, thereby improving the waste collection efficiency and the convenience of grinding.

[0089] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0090] Reference Figure 1 and Figure 2 , a method for detecting a car USB interface, comprising the following steps:

[0091] Step 100: Obtain a detection weight value of a preset detection area.

[0092] The detection area refers to the area used to detect the finished automotive USB interface 1. The automotive USB interface 1 consists of an interface body and a wrapping piece used to wrap and protect the interface. The detection area is set in advance by a person skilled in the art and will not be described in detail here. The detection weight value refers to the weight value of the automotive USB interface 1. The detection weight value is measured and obtained by a weight sensor on the detection area.

[0093] Step 101: Based on the situation that the detected weight value is inconsistent with the preset reference weight value, the detected image information is obtained.

[0094] The reference weight value refers to the weight value when the weight of the automobile USB interface 1 is qualified. The reference weight value is set in advance by those skilled in the art and will not be described in detail here. The detection image information refers to the image of the automobile USB interface 1 in the detection area. The detection image information is obtained by taking a photo with a camera.

[0095] When the detected weight value is inconsistent with the reference weight value, it indicates that the weight of the vehicle USB interface 1 is abnormal, and the detected image information needs to be obtained for subsequent steps.

[0096] Step 102: Based on the fact that the detected image information does not contain the preset burr feature, an interface abnormality prompt is reported.

[0097] The burr feature refers to the feature when there is burr on the package. The interface abnormality prompt refers to the prompt issued when the weight abnormality of the car USB interface 1 occurs, and the weight abnormality is not caused by the burr. The burr feature and the interface abnormality prompt are set in advance by those skilled in the art and will not be described in detail here.

[0098] When the detected image information does not contain burr features, it means that there is no burr on the package, and the interface abnormality prompt needs to be reported for subsequent steps.

[0099] Step 103: Based on the fact that the detected image information contains burr features, determine the burr position and burr range according to the detected image information and the burr features.

[0100] The burr position refers to the position of the burr on the package. The burr range refers to the range of the burr extending outward from the side wall of the package. The burr features can be identified and marked from the detection image information through the preset image recognition library, so as to obtain the burr position and burr range. The image recognition library contains the corresponding relationship between the detection image information, burr features, burr position and burr range. The image recognition library is a manually set database and will not be described in detail here.

[0101] When the detected image information contains burr features, it means that there are burrs on the package. The burr position and burr range must be identified and marked first for subsequent steps.

[0102] Step 104: Match a removal method from a preset processing database according to the burr position and burr range.

[0103] The removal method refers to a method for removing burrs. The specific removal method is described in detail in the subsequent steps 200 to 206, and will not be described in detail here. The removal method corresponding to the burr position and burr range can be matched by processing the database, which includes the corresponding relationship between the burr position and burr range and the removal method. The processing database is a manually set database, and will not be described in detail here.

[0104] Step 105: Control a preset processing device to remove the burr feature using a removal method.

[0105] The processing device refers to a device for removing burrs on a package. The processing device is controlled to remove burrs by a removal method.

[0106] Reference Figure 1 and Figure 3 , the removal method comprises the following steps:

[0107] Step 200: Based on the fact that the burr position is consistent with the preset edge position, edge grinding parameters are matched from a preset grinding database according to the burr position and the burr range.

[0108] The edge position refers to the position of the outer wall portion that is not in contact with the interface body on the package of the car USB interface 1. The edge position is set in advance by a person skilled in the art and will not be described in detail here. The edge grinding parameter refers to the grinding force and grinding depth used to grind and remove the burrs located at the edge position. The edge grinding parameters corresponding to the burr position and burr range can be matched through the grinding database, which includes the correspondence between the burr position and burr range and the edge grinding parameters. The grinding database is an artificially set database and will not be described here.

[0109] When the burr position is consistent with the edge position, it means that the burr is located at the outermost edge of the package. The edge grinding parameters need to be matched for subsequent steps.

[0110] Step 201: Control a preset grinding device to grind and remove burr features according to edge grinding parameters.

[0111] The grinding device refers to a device for grinding and removing burrs. The grinding device is controlled to grind and remove burrs according to edge grinding parameters.

[0112] Step 202: Based on the inconsistency between the burr position and the edge position, determine the interface range according to the detected image information and the preset interface features.

[0113] The interface characteristics refer to the characteristics of the interface of the automobile USB interface 1. The interface range refers to the range size of the interface. The interface characteristics are set in advance by those skilled in the art and will not be described in detail here.

[0114] When the burr position is inconsistent with the edge position, it means that the burr is located on the package close to the interface. The image recognition library is required to identify the interface features in the detection image information, so as to identify the interface range for subsequent steps. The image recognition library contains the correspondence between the detection image information, interface features and interface range.

[0115] Step 203: Match the burr margin from a preset interface database according to the interface range and the preset reference range.

[0116] The reference range refers to the range that should be reached at the interface. The reference range is set in advance by a person skilled in the art and will not be described in detail here. The burr margin refers to the length of the burr extending outward. The burr margin corresponding to the interface range and the reference range can be matched through the interface database, which includes the corresponding relationship between the interface range and the reference range and the burr margin. The interface database is a manually set database and will not be described in detail here.

[0117] Step 204: Based on the situation that the burr margin exceeds the preset reference margin, the difference between the burr margin and the reference margin is calculated as the burr difference value.

[0118] The reference margin refers to the longest margin that can be directly polished to remove the burrs. The reference margin is set in advance by a person skilled in the art and will not be described in detail here. The burr difference value refers to the length difference between the burr margin and the reference margin. The burr difference value can be obtained by calculating the difference between the burr margin and the reference margin.

[0119] When the burr margin exceeds the reference margin, it means that it is too time-consuming to directly use a grinding device to grind and remove the burrs, and the burr difference value must be calculated first for subsequent steps.

[0120] Step 205: Match the heating temperature value from the processing database according to the burr difference value and the preset interface material information.

[0121] The heating temperature value refers to the temperature value used to heat and remove the burrs. The interface material information refers to the material of the wrapping piece used to wrap and protect the automotive USB interface 1. The interface material information is set in advance by those skilled in the art and will not be described in detail here.

[0122] The heating temperature value corresponding to the burr difference value and the interface material information can be matched by processing the database, which includes the corresponding relationship between the burr difference value, the interface material information and the heating temperature value.

[0123] Step 206: Control a preset heating device to heat the burr feature according to the heating temperature value, and control a grinding device to grind and remove the burr feature according to preset reference grinding parameters after heating.

[0124] The heating device refers to a device for heating the burrs to remove the burrs. The reference grinding parameters refer to the reference strength and depth of the grinding device when grinding. The reference grinding parameters are set in advance by those skilled in the art and will not be described in detail here.

[0125] The heating device is controlled to heat the burr feature at a heating temperature value to remove excess burr, and after heating, the grinding device is controlled to grind and remove the remaining burr feature at a reference grinding parameter.

[0126] Reference Figure 1 and Figure 4 , the removal method further comprises the following steps:

[0127] Step 300: Based on the fact that the detected image information does not contain burr features, determine whether the detected image information contains interface features.

[0128] When the detection image information does not contain burr features, it means that there are no burrs on the package. It is necessary to determine whether the detection image information contains interface features to know the opening conditions of the interface on the package, and then know the specific reasons for the abnormal weight of the car USB port 1.

[0129] Step 301: Based on the fact that the detected image information does not contain interface features, a preset lighting device is controlled to perform lighting with a preset lighting intensity value, and lighting image information is obtained.

[0130] The lighting device refers to a device used to light a package without openings at the interface. The lighting intensity value refers to the brightness value of the package without openings at the interface. The lighting image information refers to the image of the package after lighting. The lighting intensity value is set in advance by a person skilled in the art and will not be described in detail here. The lighting image information is obtained by taking a photo with a camera.

[0131] When the detected image information does not contain the interface feature, it means that there is no opening at the interface on the package, so the material that should be removed from the package is retained, which leads to the abnormal weight of the car USB interface 1. It is necessary to control the lighting equipment to light the package with the lighting intensity value and obtain the lighting image information for subsequent steps.

[0132] Step 302: Based on the fact that the lighting image information contains a preset light transmission characteristic, determine the light transmission range and the light transmission intensity value according to the lighting image information and the light transmission characteristic.

[0133] The light transmittance characteristic refers to the characteristic of light passing through the package when the lighting equipment illuminates the package. The light transmittance characteristic is set in advance by those skilled in the art and will not be elaborated here. The light transmittance range refers to the range where the light transmittance characteristic is located on the entire package. The light transmittance intensity value refers to the intensity of light after the light passes through the package. The light transmittance range and light transmittance intensity value corresponding to the lighting image information and the light transmittance characteristic can be matched through the preset lighting database, which includes the corresponding relationship between the lighting image information, the light transmittance characteristic, the light transmittance range and the light transmittance intensity value. The lighting database is an artificially set database and will not be elaborated here.

[0134] When the lighting image information contains light transmission features, it means that the package on the interface is not thick and can be removed by heating. The light transmission range and light transmission intensity value must be matched first for subsequent steps.

[0135] Step 303: Match the removal thickness value from a preset material database according to the lighting intensity value, the light transmittance intensity value and the interface material information.

[0136] The removal thickness value refers to the thickness value that needs to be removed from the package at the interface. The material database can match the lighting intensity value, light transmittance value and the thickness value corresponding to the interface material information, which contains the corresponding relationship between the lighting intensity value, light transmittance value, interface material information and the thickness value. The material database is a manually set database and will not be described here.

[0137] Step 304: Determine the heating range according to the light transmission range.

[0138] The heating range refers to the range of heating the package to remove the package at its interface. The heating range corresponding to the light transmittance range can be matched through a preset heating database, which includes the corresponding relationship between the light transmittance range and the heating range. The heating database is a manually set database and will not be described here.

[0139] Step 305: Determine the removal temperature value according to the removal thickness value, the interface material information, and the heating range.

[0140] The removal temperature value refers to the temperature value when the package is heated to remove the package at its interface. The removal thickness value and the interface material information and the removal temperature value corresponding to the heating range can be matched through the heating database, which contains the algorithm formula for calculating the removal temperature value: T = (Pt) / (ρShc) + T0, where T is the removal temperature value, P is the heating power, t is the heating time, ρ is the material density corresponding to the interface material information, S is the heating range, h is the removal thickness value, c is the specific heat capacity, and T0 is the initial temperature. P, t, c, T0 and ρ are obtained by prior testing by technicians in this field and will not be repeated here.

[0141] Step 306: Controlling the heating device to heat the heating range according to the removal temperature value.

[0142] The heating device is controlled to heat the heating range at a removal temperature value, so as to remove the wrapping at the interface and thereby reveal the interface.

[0143] Reference Figure 1 and Figure 5 , the interface removal method comprises the following steps:

[0144] Step 400: Based on the fact that the lighting image information does not contain a light-transmitting feature, the current interface posture is determined according to the lighting image information and a preset interface reference posture.

[0145] The interface reference posture refers to the appearance posture of the standard automobile USB interface 1 in a normal state. The interface reference posture is set in advance by those skilled in the art and will not be described in detail here. The current interface posture refers to the appearance posture of the current automobile USB interface 1.

[0146] When the lighting image information does not contain light-transmitting features, it means that the package that blocks the interface is too far back, so that light cannot pass through the package. It is necessary to match the lighting image information and the current interface posture corresponding to the interface reference posture through a preset posture database for subsequent steps. The posture database contains the corresponding relationship between the lighting image information and the interface reference posture and the current interface posture. The posture database is a manually set database and will not be described in detail here.

[0147] Step 401: Determine the interface position according to the current interface posture and preset surrounding material features.

[0148] Peripheral material features refer to the appearance features of the material around the interface. The peripheral material features are set in advance by those skilled in the art and will not be described in detail here. The interface position refers to the position of the interface on the package. The interface position corresponding to the current interface posture and the peripheral material features can be matched through a preset interface database, which contains the corresponding relationship between the current interface posture and the peripheral material features and the interface position. The interface database is a manually set database and will not be described in detail here.

[0149] Step 402: Determine the cutting path according to the interface position and the preset interface size.

[0150] The interface size refers to the size of the interface. The interface size is set in advance by a technician in this field and will not be described in detail here. The resection path refers to the route for resecting the package that blocks the interface. The resection path corresponding to the interface position and interface size can be matched through the preset resection database, which contains the correspondence between the interface position and interface size and the resection path. The resection database is a manually set database and will not be described in detail here.

[0151] Step 403: Control a preset cutting device to cut the interface position at a preset reference cutting depth according to the cutting path, and after cutting, control a lighting device to light at a lighting intensity value.

[0152] The cutting device refers to a device for cutting the package that blocks the interface. The reference cutting depth refers to the depth for cutting the package that blocks the interface. The reference cutting depth is set in advance by a person skilled in the art and will not be described in detail here.

[0153] The cutting device is controlled to cut the interface position along the cutting path at a reference cutting depth, and after cutting, the lighting device is controlled to light the interface position at a lighting intensity value for subsequent steps.

[0154] Step 404: Acquire a cut-out lighting image.

[0155] The excision lighting image refers to the image when the excision device excises the interface position at the reference excision depth and the lighting device illuminates the interface position at the lighting intensity value. The excision lighting image is obtained by taking a photo with a camera.

[0156] Step 405: Based on the fact that the cut-out lighting image contains a light transmission feature, determine the path light transmission intensity value according to the cut-out lighting image and the light transmission feature.

[0157] The path light transmittance value refers to the light transmittance value on the path after the excision device cuts along the excision path. The path light transmittance value corresponding to the excision lighting image and the light transmittance feature can be matched through the lighting database, which includes the correspondence between the excision lighting image and the light transmittance feature and the path light transmittance value.

[0158] When the cut-out illuminated image contains light-transmitting features, the path light-transmitting intensity value needs to be matched for subsequent steps.

[0159] When the cut-out lighting image does not contain the light-transmitting feature, it means that the package is still too thick and the interface position needs to be cut again, and steps 403 to 405 can be repeated.

[0160] Step 406: Match the path thickness change from the material database according to the path light transmittance value, the lighting intensity value and the interface material information.

[0161] The path thickness change refers to the change in the remaining thickness of the package on the cut path after the package at the interface position is cut. The path light transmittance value, lighting intensity value and interface material information corresponding path thickness change can be matched through the material database, which includes the corresponding relationship between the path light transmittance value, lighting intensity value, interface material information and path thickness change.

[0163] The excess material removal method refers to a method for removing the excess packaging parts remaining at the interface position. The specific excess material removal method is described in detail in the subsequent steps 500 to 504, and will not be repeated here.

[0164] Reference Figure 6 The excess material removal method comprises the following steps:

[0165] Step 500: When the path thickness change is consistent with the preset reference thickness change, the remaining thickness value is matched from the material database according to the path light transmittance value, the lighting intensity value and the interface material information.

[0167] Step 501: Controlling a cutting device to cut the interface position along a cutting path according to the remaining thickness value.

[0168] The cutting device is controlled to cut the interface position along the cutting path according to the remaining thickness value, so as to open the interface.

[0169] Step 502: When the path thickness variation is consistent with the preset path thickness abnormality, a segmentation area is matched from a preset excision database according to the path thickness variation.

[0170] The path thickness abnormality refers to the situation when the remaining thickness values ​​on the resection path are inconsistent. The path thickness abnormality is set in advance by technical personnel in this field and will not be elaborated here. The cutting area refers to dividing the excess packages that need to be cut off at the interface into multiple small areas. The area divided in this way is the cutting area. The cutting area corresponding to the path thickness change can be matched through the cutting database, which contains the correspondence between the path thickness change and the cutting area. The cutting database is an artificially set database and will not be elaborated here.

[0171] When the path thickness change is consistent with the path thickness anomaly, it means that the remaining thickness value on the resection path is inconsistent, and the segmentation area needs to be matched for subsequent steps.

[0172] Step 503: Matching a segmentation path from a segmentation database according to the segmentation area and the segmentation path.

[0173] The segmentation path refers to the path for cutting the segmentation area. The segmentation path corresponding to the segmentation area and the segmentation path can be matched through the cutting database, which includes the corresponding relationship between the segmentation area and the cutting path and the segmentation path.

[0174] Step 504: Controlling the cutting device to cut the cutting area according to the cutting path.

[0175] The cutting device is controlled to cut the cutting area along the cutting path, thereby gradually opening the interface.

[0176] Reference Figure 7 , the smoke collection method comprises the following steps:

[0180] The smoke direction refers to the drifting direction of the smoke generated when the heating device heats and removes the package and the burrs. The combustion database can match the smoke direction corresponding to the current wind direction information and the interface material information.

[0183] Step 603: Determine the magnitude relationship between the heating temperature value and the removal temperature value, and define the larger temperature value as the suction temperature value.

[0184] The suction temperature value refers to the larger temperature value between the heating temperature value and the removal temperature value as the suction temperature value. The suction temperature value is known by comparing the size relationship between the heating temperature value and the removal temperature value. When the heating temperature value is greater than the removal temperature value, the heating temperature value is used as the suction temperature value. When the removal temperature value is greater than the heating temperature value, the removal temperature value is used as the suction temperature value. And when the heating temperature value is the same as the removal temperature value, the heating temperature value is used as the suction temperature value by default.

[0185] By comparing the size relationship between the heating temperature value and the removal temperature value, the suction temperature value can be known for subsequent steps.

[0186] Step 604: Determine the suction force value according to the suction temperature value.

[0187] The suction force value refers to the suction force value used to remove the smoke generated when the heating device heats and removes the package and the burrs. The suction force value corresponding to the suction temperature value can be matched through the preset suction database, which contains the corresponding relationship between the suction temperature value and the suction force value. The suction database is a manually set database and will not be described in detail here.

[0188] Step 605: Control the preset suction device to move to the suction position, and at the suction position, control the suction device to suck air in the suction direction with the suction force value.

[0189] The suction device is controlled to move to the suction position, and at the suction position, the suction device is controlled to suction in the suction direction with a suction force value to remove the smoke generated when the heating device heats and removes the package and burrs, so as to facilitate subsequent steps.

[0193] Reference Figure 8 , the foreign matter collection method comprises the following steps:

[0194] Step 700: When heating the burr feature and the heating range based on the heating device, the heating position is obtained.

[0195] The heating position refers to the position on the burr or package where the heating device acts when the heating device heats the burr or package. First, by understanding the position of the heating device and the device size of the heating device, the heating position corresponding to the device position and device size can be matched through the preset position database. It contains the correspondence between the device position and device size and the heating position. The position database is a manually set database and will not be described here. The position of the heating device is obtained through the GPS positioning chip on the heating device. The device size refers to the size of the heating device. The device size is set in advance by a technician in this field and will not be described here.

[0197] The collecting device is a device used to collect waste generated when the heating device heats the burr feature or the heating range. The collecting device is controlled to move to the right below the heating position to collect the waste dropped by heating.

[0198] Step 702: Acquire heating image information.

[0199] The heating image information refers to an image when the heating device heats the burr feature or the heating range. The heating image information is obtained by taking a picture with a camera.

[0200] Step 703: Based on the fact that the heated image information contains preset foreign object features, the location of the foreign object is marked according to the heated image information and the foreign object features.

[0201] Foreign body features refer to waste materials that adhere to the package and do not fall off after heating. Foreign body features are set in advance by those skilled in the art and will not be described in detail here. Foreign body location refers to the location of the foreign body on the package. Foreign body features can be identified from the heated image information through a preset feature recognition library, and the foreign body features are marked to obtain the foreign body location. The feature recognition library is obtained based on deep learning of a neural network model, which includes foreign body features and foreign body locations.

[0202] When the heated image information contains foreign body features, it means that the waste is adhered to the package. The foreign body features need to be marked to obtain the location of the foreign body for subsequent steps.

[0205] Step 705: When the clamping device clamps and grasps the foreign object features at the foreign object position, the collecting device is controlled to move to the foreign object position to collect the crushed and fallen foreign objects.

[0206] When the clamping device clamps and grasps the foreign object features at the foreign object position, the collecting device is controlled to move to just below the foreign object position to collect the crushed and fallen foreign objects.
