[0003] When manufacturing a car's USB interface, usually the various components required for the USB interface are produced first, then the components are assembled, and after assembly, the USB interface is finally tested before production is completed.

[0004] When assembling various parts, in order to facilitate assembly, workers are usually required to manually observe the position of the parts. If there is an abnormal position, the position of the parts needs to be manually adjusted, which reduces work efficiency and needs to be improved. Summary of the invention

[0007] By adopting the above technical solution, the image information of the assembly area is first obtained and compared with the reference placement feature of the object to determine the current placement feature. If the two are inconsistent, the posture adjustment parameters are calculated, and the posture adjustment device is used to adjust the posture of the light-guiding object according to the parameters. After the posture adjustment is completed, the clamping device is controlled to clamp the light-guiding object to the pre-installation area for pre-installation, thereby improving work efficiency.

After the installation is completed, control the preset detection device to detect the circuit board assembly and obtain the detection signal; When the detection signal is consistent with the preset qualified signal, the preset pressing device is controlled to press the circuit board assembly; After the pressing is completed, the clamping device is controlled to clamp the circuit board assembly and insert it into a preset housing, and the surface image information is obtained; Determine the installation posture of the base according to the surface image information and the preset installation features; The clamping device is controlled to pre-install the preset base on the shell in the base installation posture, and the preset pressing device is controlled to press the shell and the base to complete the installation.

[0009] By adopting the above technical solution, after the light-guiding object is pre-installed, the interface image information of the circuit board assembly is first obtained to determine the installation position, and then the clamping device is controlled to accurately install the light-guiding object to the corresponding position. After the installation is completed, the detection device is used to detect the circuit board assembly and obtain the detection signal. When the detection signal is consistent with the qualified signal, the pressing device is started to press the circuit board assembly. After the pressing is completed, the circuit board assembly is inserted into the shell through the clamping device, and the installation posture of the base is determined according to the obtained surface image information, and then the clamping device is controlled to pre-install the base on the shell according to this posture. Finally, the shell and the base are pressed with the help of a press device, thereby completing the installation process of the entire automotive USB interface, thereby further improving work efficiency.

[0010] Optionally, also include the test method: After the installation is completed, the preset test device is controlled to connect the power of the USB interface and obtain the detection image information of the USB interface; When the detected image information contains a preset light leakage feature, the clamping device is controlled to clamp the USB interface to perform light leakage detection using a preset light leakage detection method, and the light leakage detection situation is output; According to the light leakage detection situation, a light leakage processing method is matched from a preset processing database; Controlling a preset repair device to repair the USB interface according to the light leakage processing method; When the detected image information does not contain a preset light leakage feature, controlling a preset interface detection device to perform a plug-in detection on the USB interface in a preset plug-in detection sequence and a preset plug-in force value, and obtaining a plug-in detection signal after the detection is completed; When the plug-in detection signal is inconsistent with the preset qualified detection signal, a plug-in abnormal prompt is reported.

[0011] By adopting the above technical solution, after the installation of the car USB interface, first turn on the power to obtain the detection image. If there is a light leakage feature, the clamping device detects it according to a specific method, matches the repair method according to the result, and controls the repair device for processing; if there is no light leakage feature, the interface detection device detects according to the preset plug-in sequence and force, and obtains the plug-in detection signal after the completion. If this signal does not match the qualified signal, the plug-in abnormal prompt is immediately reported to improve the product yield.

[0012] Optionally, the light leakage detection method includes: When the detected image information contains the light leakage feature, determining whether the detected image information contains the preset foreign body feature; When the detected image information contains features of foreign matter, the location of the foreign matter is determined based on the detected image information, the features of the foreign matter and a preset reference object; Determine the clamping position and cutting position according to the position of the foreign body and the preset USB interface parameters; Controlling the clamping device to clamp the clamping position of the foreign body feature, and controlling the preset cutting device to cut the cutting position to remove the foreign body; When the detected image information does not contain foreign body features, the clamping device is controlled to shake the USB interface with a preset shaking amplitude value, and shaking image information is obtained; Determine the light leakage variation value according to the shaking image information and the light leakage characteristics; When the light leakage variation value exceeds the preset reference variation value, a light leakage abnormality prompt is reported; When the light leakage variation amplitude value does not exceed the preset reference variation amplitude value, the repair device is controlled to repair the USB interface according to the light leakage processing method.

[0013] By adopting the above technical solution, when it is detected that the detection image information of the USB interface contains light leakage characteristics, it will first determine whether there are foreign body characteristics. If so, the position of the foreign body is immediately locked, and the USB interface is accurately clamped by a clamping device to cut and remove the foreign body, directly hitting the source of the light leakage; if no foreign body characteristics are found, the USB interface is shaken to obtain the shaking image, and the light leakage change amplitude is calculated by comparing the light leakage characteristics. Once the amplitude value exceeds the benchmark, an abnormal prompt is immediately reported to facilitate subsequent investigation; if it does not exceed the benchmark, the repair device is directed to repair the interface according to the light leakage processing method, thereby improving the product quality of the USB interface.

[0014] Optionally, light leakage processing methods include: Controlling a preset disassembling device to disassemble the USB interface, and after disassembly, controlling a clamping device to clamp the circuit board assembly out of the housing, and obtaining circuit board image information; Determine the interface angle value based on the circuit board image information, interface features and reference objects; When the interface angle value is inconsistent with the preset reference angle value, the adjustment angle value is determined according to the interface angle value and the reference angle value; According to the adjustment angle value, the clamping device is controlled to clamp the USB interface to adjust the angle; When the interface angle value is consistent with the preset reference angle value, obtaining the interface model information of the USB interface; Determine the shaking of the interface based on the interface model information and the light leakage variation value; Determine the repair position and the material usage value corresponding to the repair position according to the shaking condition of the interface; The control repair device repairs the repair position according to the material dosage value. After the repair, the control clamping device clamps the circuit board assembly into the shell, and the assembly of the USB interface is completed.

[0015] By adopting the above technical solution, when encountering a USB interface light leakage problem that needs to be dealt with, first start the disassembly device to disassemble the USB interface, remove the circuit board assembly and obtain the circuit board image information. With the image information, interface characteristics and reference objects, calculate the interface angle value, compare it with the reference angle value, and if it is inconsistent, determine the adjustment angle value according to the difference, and operate the clamping device to calibrate the angle; if it is consistent, obtain the interface model information, combine the light leakage change amplitude value to determine the interface shaking situation, and then clarify the repair position and material usage value, and let the repair device perform the repair. After the repair is completed, install the circuit board assembly back into the shell to complete the assembly, so as to efficiently solve the light leakage risk and ensure the quality of the USB interface.

[0016] Optionally, also include shake detection method: After the installation is completed, the clamping device is controlled to clamp the shell and shake it in a preset shaking sequence and a preset shaking amplitude value, and shaking sound information is obtained; When the shaking sound information is consistent with the preset object falling sound information, the sound source position is determined according to the shaking sound information, and the shaking duration is obtained; Determine the location of the fallen object based on the shaking sequence, shaking amplitude, sound location, and shaking duration; Determine the fallen object according to the position of the fallen object and the preset circuit board arrangement information; According to the fallen object, a preset signal transceiver terminal is controlled to report an object abnormality prompt corresponding to the fallen object, and the shaking sequence is updated based on the position of the fallen object.

[0017] By adopting the above technical solution, after the installation of the car USB interface is completed, in order to ensure the stability of the internal components, the clamping device is controlled to shake the shell according to the preset shaking order and amplitude value to collect shaking sound information. Once the information matches the preset sound of the object falling off, the location of the sound source is immediately determined based on it, and the shaking duration is recorded at the same time. The position of the fallen object is accurately located by combining various shaking parameters, and the circuit board arrangement information is combined to clarify what the fallen object is. Subsequently, the corresponding abnormal prompt is reported with the help of the signal transceiver terminal, so that the staff can know the problem in time, and can also optimize the shaking order based on the feedback of the position of the fallen object, providing more accurate guidance for subsequent detection and improving detection efficiency.

[0018] Optionally, the shaking detection method further includes: When the shaking sound information is consistent with the preset abnormal sound information of the shell, the shell image information is obtained; When the shell image information does not contain a preset shell crack feature, determining the shell difference feature according to the shell image information and the preset reference image information; When the shell difference feature is consistent with the preset position offset feature, determining the shell offset value according to the shell difference feature; Determine a corrected snap-in position according to the shell offset value and a preset reference snap-in position; Controlling the preset disassembly device to disassemble the USB interface, and after the disassembly is completed, controlling the clamping device to correct the position of the housing according to the correction clamping position; After the position is corrected, the press equipment is controlled to re-press the housing and the base to complete the installation.

[0019] By adopting the above technical solution, when the shaking sound information is consistent with the preset abnormal sound information of the shell, the shell image information is first obtained. If the preset shell crack characteristics are not presented in the image information, the shell image information and the preset reference image information are compared to determine the shell difference characteristics. If the shell difference characteristics are consistent with the preset position offset characteristics, the shell offset value is determined based on the difference characteristics, and then the clamping position is clearly corrected in combination with the preset reference clamping position. Subsequently, the USB interface is disassembled using a disassembly device, and the clamping device is controlled to correct the position of the shell according to the corrected clamping position, and finally the shell and the base are re-pressed by a press device to complete the installation. In this way, the shell position offset problem can be effectively checked and solved, and the installation quality of the USB interface can be guaranteed.

[0020] Optionally, post-compression detection methods are also included: After re-compression, obtaining compressed image information; When the post-compression image information includes shell crack features, the shell crack position and shell crack size are determined according to the post-compression image information, the shell crack features and a preset reference object; When the shell crack position is consistent with the preset clamping position, the clamping image information is obtained; When the snap-fit ​​image information contains a preset snap-fit ​​feature, the amount of repair material is determined according to the shell crack size; According to the amount of repair material used, the preset repair equipment is controlled to repair the shell crack position; When the preset snap-on features are not included in the snap-on image information, an interface abnormality prompt is reported.

[0021] By adopting the above technical solution, after the shell and the base are re-pressed, the post-pressing image information is immediately obtained to monitor the status of the shell. Once it is found that the post-pressing image information contains the shell crack characteristics, the shell crack position is accurately located based on the information, the shell crack characteristics and the preset reference object, and the shell crack size is measured. When the shell crack position coincides with the preset snap-on position, the snap-on image information is obtained to check whether it contains the preset snap-on feature: if it does, the amount of repair material can be determined according to the shell crack size, and then the repair equipment can be controlled to accurately repair the crack position; if it does not, the interface abnormality prompt is reported in time to let the staff know the problem quickly so that further measures can be taken to fully guarantee the quality and stability of the assembled automotive USB interface.

If there is a light leakage feature, the clamping device will detect it according to a specific method, match the repair method according to the result, and operate the repair device to handle it; if there is no light leakage feature, the interface detection equipment will detect it according to the preset plug-in sequence and force, and obtain the plug-in detection signal after completion. If this signal does not match the qualified signal, the plug-in abnormal prompt will be reported immediately to improve the product yield; 3.

[0068] When the plug-in detection signal is inconsistent with the qualified detection signal, it means that the plug-in detection of the USB interface is unqualified and a plug-in abnormal prompt needs to be reported.

[0069] When the plug-in detection signal is consistent with the qualified detection signal, it means that the plug-in detection of the USB interface is qualified and the detection is completed.

[0070] Reference Figure 1 and Figure 3 , the light leakage detection method comprises the following steps: Step 400: When the detected image information contains a light leakage feature, determine whether the detected image information contains a preset foreign matter feature.

[0071] Foreign body features refer to features of foreign bodies at the interface. When foreign bodies are present at the interface, the position of the interface will be offset, which will lead to light leakage features. Foreign body features are set in advance by those skilled in the art and will not be described here. When the detected image information contains light leakage features, it is necessary to determine whether the detected image information contains foreign body features in order to know whether the USB interface light leakage is caused by foreign bodies.

[0072] Step 401: When the detected image information contains features of foreign matter, the location of the foreign matter is determined according to the detected image information, the features of the foreign matter and a preset reference object.

[0073] A reference object refers to an object used to assist in measuring the position of a foreign body feature at the interface. The size and position of the reference object are set in advance by a person skilled in the art and will not be described in detail here. The detection image information contains a reference object. The foreign body position refers to the specific position of the foreign body feature at the interface. By knowing the position and size of the foreign body feature in the detection image information, and then comparing the position and size of the reference object in the detection image information, the actual foreign body position can be known. When the detection image information contains foreign body features, it means that the light leakage of the USB interface is caused by the influence of foreign matter, and the position of the foreign matter needs to be determined for subsequent steps.

[0074] Step 402: Determine the clamping position and the cutting position according to the position of the foreign object and the preset USB interface parameters.

[0075] The USB interface parameters refer to the size and material of the USB interface. The clamping position refers to the position where the foreign body feature is clamped when the foreign body feature is cut off. The cutting position refers to the position where the cutting device cuts when cutting off the foreign body feature. The clamping position and cutting position corresponding to the foreign body position and the USB interface parameters can be matched through the preset removal database, which contains the correspondence between the foreign body position, USB interface parameters, clamping position and cutting position. The removal database is a manually set database and will not be described here.

[0076] Step 403: Control the clamping device to clamp the clamping position of the foreign body feature, and control the preset cutting device to cut the cutting position to remove the foreign body.

[0077] The cutting device is a device used to cut off the foreign body features. The clamping device is controlled to clamp the clamping position of the foreign body features, and after clamping, the cutting device is controlled to cut the cutting position. After cutting, the clamping device is controlled to clamp and remove the foreign body features.

[0078] Step 404: When the detected image information does not contain foreign body features, the clamping device is controlled to shake the USB interface with a preset shaking amplitude value, and shaking image information is obtained.

[0079] The shaking amplitude value refers to the amplitude value used to shake the USB interface to check the change in light leakage. The shaking amplitude value is set in advance by a person skilled in the art and will not be described in detail here. The shaking image information refers to the image when the USB interface is shaken. The shaking image information is obtained by taking a photo with a camera. When the detected image information does not contain foreign matter features, it means that the cause of the light leakage of the USB interface is not foreign matter, and the clamping device needs to be controlled to shake the USB interface with the shaking amplitude value, and obtain the shaking image information for subsequent steps.

[0080] Step 405: Determine the light leakage variation amplitude value according to the shaking image information and the light leakage characteristics.

[0081] The light leakage variation amplitude value refers to the amplitude value of the light leakage feature changing in size when the USB interface is shaken. The light leakage variation amplitude value corresponding to the shaking image information and the light leakage feature can be matched through the preset light leakage database, which contains the correspondence between the shaking image information and the light leakage feature and the light leakage variation amplitude value. The light leakage database is a manually set database and will not be elaborated here.

[0082] Step 406: When the light leakage variation amplitude value exceeds a preset reference variation amplitude value, a light leakage abnormality prompt is reported.

[0083] The reference variation amplitude value refers to the maximum value that the light leakage variation amplitude value can reach. The light leakage abnormality prompt refers to the prompt when the light leakage of the USB interface cannot be repaired. The reference variation amplitude value and the light leakage abnormality prompt are both set in advance by those skilled in the art and will not be described in detail here.

[0084] When the light leakage variation value exceeds the reference variation value, it indicates that the light leakage of the current USB interface cannot be repaired and a light leakage abnormality prompt needs to be reported.

[0085] Step 407: When the light leakage variation amplitude value does not exceed the preset reference variation amplitude value, control the repair device to repair the USB interface according to the light leakage processing method.

[0086] When the light leakage variation amplitude value does not exceed the reference variation amplitude value, it indicates that the current light leakage situation of the USB interface can be repaired, and the repairing device needs to be controlled to repair the USB interface using a light leakage processing method.

[0087] Reference Figure 1 and Figure 4 , the light leakage processing method includes the following steps: Step 500: Control the preset disassembly device to disassemble the USB interface. After the disassembly, control the clamping device to clamp the circuit board assembly 3 out of the housing 1 and obtain the circuit board image information.

[0088] The disassembly device refers to a device for separating and disassembling the housing 1 and the base 2 of the USB interface. The circuit board image information refers to the image of the circuit board assembly 3. The circuit board image information is obtained by taking a photo with a camera. The disassembly device is controlled to disassemble the USB interface, and after the disassembly, the clamping device is controlled to clamp the circuit board assembly 3 out of the housing 1, and then the circuit board image information is obtained for subsequent steps.

[0089] Step 501: Determine the interface angle value according to the circuit board image information, interface characteristics and reference objects.

[0090] The interface angle value refers to the angle value formed by the interface of the USB interface relative to the horizontal direction. The interface angle value corresponding to the circuit board image information, interface features and reference objects can be matched through the preset angle database, which contains the corresponding relationship between the circuit board image information, interface features, reference objects and interface angle values. The angle database is a manually set database and will not be described here.

[0091] Step 502: When the interface angle value is inconsistent with the preset reference angle value, an adjustment angle value is determined according to the interface angle value and the reference angle value.

[0092] The reference angle value refers to the angle value at which the interface angle value should be. The reference angle value is set in advance by a person skilled in the art and will not be described in detail here. The angle adjustment value refers to the value for adjusting the angle at the interface of the USB interface. The adjustment angle value can be obtained by calculating the difference between the interface angle value and the reference angle value. When the interface angle value is inconsistent with the reference angle value, it means that the factor causing the light leakage of the USB interface is due to the tilt at the interface, and the adjustment angle value needs to be determined for subsequent steps.

[0093] Step 503: Control the clamping device to clamp the USB interface to adjust the angle according to the adjustment angle value.

[0094] The clamping device is controlled to adjust the angle of the interface of the USB interface by adjusting the angle value.

[0095] Step 504: When the interface angle value is consistent with a preset reference angle value, the interface model information of the USB interface is obtained.

[0096] The interface model information refers to the model of the USB interface. By understanding the model of the USB interface, you can know the specific structure of the USB interface and the installation position of the internal components. The interface model information is obtained by scanning the QR code on the shell 1 with a preset scanner. The content obtained by scanning the QR code corresponds to the interface model information. When the interface angle value is consistent with the reference angle value, it means that the factor causing the light leakage of the USB interface is not due to the tilt of the interface, and the interface model information of the USB interface needs to be obtained for subsequent steps.

[0097] Step 505: Determine the shaking condition of the interface according to the interface model information and the light leakage variation amplitude value.

[0098] The interface shaking condition refers to the amplitude and direction of shaking of the USB interface as the USB interface shakes. The interface shaking condition corresponding to the interface model information and the light leakage variation amplitude value can be matched through the preset shaking database, which contains the corresponding relationship between the interface model information, the light leakage variation amplitude value and the interface shaking condition. The shaking database is a manually set database and will not be described here.

[0099] Step 506: Determine the repair position and the material usage value corresponding to the repair position according to the shaking condition of the interface.

[0100] The repair position refers to the position where the interface is repaired to prevent further light leakage at the interface. The material usage value refers to the amount of repair material required to repair the repair position. Since the interface is shaking, it means that there are positions around the interface that need to be repaired. Therefore, it is necessary to know the material usage value corresponding to the repair position.

[0101] The patching database can be used to match the patching position and material usage value corresponding to the interface shaking condition, which includes the corresponding relationship between the interface shaking condition, the patching position and the material usage value. The patching database is a manually set database and will not be described in detail here.

[0102] Step 507: Control the repair device to repair the repair position with the material usage value. After the repair, control the clamping device to clamp the circuit board assembly 3 into the housing 1, and complete the assembly of the USB interface.

[0103] The repairing device is controlled to repair the repairing position according to the material dosage value. After the repairing is completed, the clamping device is controlled to clamp the circuit board assembly 3 again and insert it into the housing 1, thereby completing the assembly of the USB interface.

[0104] The shaking detection method includes the following steps: Step 600: After the installation is completed, the clamping device is controlled to clamp the housing 1 and shake it in a preset shaking sequence and a preset shaking amplitude value, and shaking sound information is obtained.

[0105] The shaking order refers to the order in which the shell 1 is shaken after the clamping device clamps it. An example is used to illustrate the shaking order. When the shell 1 is a hexahedron, and there are six faces, namely, face A, face B, face C, face D, face E and face F. At this time, the shaking order is to first shake face A in the order of up and down, left and right, and front and back. After the shaking of face A is completed, face B is shaken immediately, and so on, until all faces are shaken. The shaking amplitude value refers to the amplitude value when the clamping device shakes the shell 1. The shaking order and the shaking amplitude value are both set in advance by those skilled in the art, and will not be elaborated here. The shaking sound information refers to the information of the sound generated inside the shell 1 when the clamping device clamps the shell 1 and shakes it. The shaking sound information is measured and obtained by a sound sensor.

[0106] After the installation of the USB interface is completed, the clamping device needs to be controlled to clamp the housing 1 and shake it in a shaking sequence and with a shaking amplitude value, and then the shaking sound information is obtained for subsequent steps.

[0107] Step 601: When the shaking sound information is consistent with the preset object falling sound information, the sound source position is determined according to the shaking sound information, and the shaking duration is obtained.

[0108] The object falling sound information refers to the sound information when the components on the circuit board assembly 3 in the shell 1 fall off. The object falling sound information is set in advance by a person skilled in the art and will not be elaborated here. The sound emission position refers to the position where the object collides with the shell 1 and makes a sound when it falls off. The sound emission position corresponding to the shaking sound information can be matched through a preset position database, which contains the correspondence between the shaking sound information and the sound emission position. The position database is an artificially set database and will not be elaborated here. The shaking duration refers to the duration of the clamping device shaking the shell 1. The shaking duration is obtained by a preset electronic timer. When the clamping device starts to shake, the electronic timer starts timing.

[0109] When the shaking sound information is consistent with the object falling sound information, it means that the components on the circuit board assembly 3 in the shell 1 have fallen off. It is necessary to first determine the location where the sound is emitted, and then obtain the shaking duration for subsequent steps.

[0110] Step 602: Determine the location of the dropped object according to the shaking sequence, shaking amplitude, sound emission location, and shaking duration.

[0111] The position of the fallen object refers to the position of the fallen object originally located on the circuit board. The preset falling database can match the falling object position corresponding to the shaking sequence, shaking amplitude value, sound emission position and shaking duration, which includes the corresponding relationship between the shaking sequence, shaking amplitude value, sound emission position, shaking duration and the falling object position. The falling database is a manually set database and will not be described here.

[0112] Step 603: Determine the fallen object according to the position of the fallen object and the preset circuit board arrangement information.

[0113] The circuit board arrangement information refers to the information on the placement of each component on the circuit board. The circuit board arrangement information is set in advance by a person skilled in the art and will not be described in detail here. The fallen object refers to the specific component that falls off the circuit board. The fallen object position and the fallen object corresponding to the circuit board arrangement information can be matched through a preset arrangement database, which contains the corresponding relationship between the circuit board arrangement information and the fallen object. The arrangement database is a manually set database and will not be described in detail here.

[0114] Step 604: According to the fallen object, a preset signal transceiver terminal is controlled to report an object abnormality prompt corresponding to the fallen object, and the shaking sequence is updated based on the position of the fallen object.

[0115] The signal transceiver terminal refers to a terminal for receiving and sending signals. In this step, the signal transceiver terminal can report the fallen object to remind the staff. The object abnormality prompt refers to the prompt when the components on the circuit board fall off. The object abnormality prompt and the signal transceiver terminal are pre-set by the technicians in this field and will not be described here.

[0116] The control signal transceiver terminal reports an abnormal object prompt corresponding to the fallen object, and updates the shaking order based on the position of the fallen object. An example of updating the shaking order is that if the sound of the fallen object occurs and the shaking surface is surface C, the shaking order is updated to surface C first.

[0117] The shaking detection method also includes the following steps: Step 700: When the shaking sound information is consistent with the preset abnormal sound information of the shell, the shell image information is obtained.

[0118] The abnormal sound information of the shell refers to the sound information when the sound emitted by the shaking is caused by the shell 1. The abnormal sound information of the shell is set in advance by a person skilled in the art and will not be described here. The shell image information refers to the image of the outer surface of the shell 1. The shell image information is obtained by taking a photo with a camera. When the shaking sound information is consistent with the abnormal sound information of the shell, it means that the sound emitted during the shaking is caused by the abnormality of the shell 1, and the shell image information needs to be obtained for subsequent steps.

[0119] Step 701: when the shell image information does not contain a preset shell crack feature, determine the shell difference feature according to the shell image information and the preset reference image information.

[0120] The shell crack feature refers to the feature when cracks appear on the outer surface of the shell 1. The shell crack feature is set in advance by a person skilled in the art and will not be described in detail here.

The reference image information is taken in advance by a person skilled in the art and will not be described in detail here. The shell difference feature refers to the difference feature between the shell 1 of the current USB interface and the shell 1 of the intact USB interface.

[0121] The shell difference features corresponding to the shell image information and the reference image information can be identified through the preset difference database, which includes the correspondence between the shell image information and the reference image information and the shell difference features. The difference database is an artificially set database and will not be described here.

[0122] When the shell image information does not contain shell crack features, it means that the cause of the abnormal sound of the shell 1 is not the crack of the shell 1, and the shell difference features need to be identified for subsequent steps.

[0123] Step 702: When the shell difference feature is consistent with the preset position offset feature, determine the shell offset value according to the shell difference feature.

[0124] The position offset feature refers to the feature when the mutual engagement between the shell 1 and the base 2 is not well matched, resulting in a position offset of the shell 1. The position offset feature is set in advance by a person skilled in the art and will not be described in detail here. The shell offset value refers to the offset size when the shell 1 is offset. The shell offset value corresponding to the shell difference feature can be matched through a preset offset database, which includes the corresponding relationship between the shell difference feature and the shell offset value. The offset database is an artificially set database and will not be described in detail here.

[0125] When the shell difference feature is consistent with the position offset feature, it means that the shell 1 has a position offset, which causes abnormal sound when the shell 1 is shaken. The shell offset value needs to be determined for subsequent steps.

[0126] When the shell difference feature is inconsistent with the position offset feature, it means that the shell 1 has not been offset and a report prompt is required.

[0127] Step 703: Determine a corrected snap-in position according to the shell offset value and a preset reference snap-in position.

[0128] The reference snap-in position refers to the position where the housing 1 should be when the housing 1 and the base 2 are snap-fitted. The reference snap-in position is set in advance by a person skilled in the art and will not be described in detail here. The corrected snap-in position refers to the reference snap-in position that needs to be corrected because the housing 1 is snap-fitted with the base 2 at the reference snap-in position, which causes the housing 1 to deviate.

[0129] The preset snap-in database can be used to match the shell offset value and the corrected snap-in position corresponding to the reference snap-in position, which includes the correspondence between the shell offset value and the reference snap-in position and the corrected snap-in position. The snap-in database is a human-set database and will not be elaborated here.

[0130] Step 704: Control the preset disassembly device to disassemble the USB interface, and after the disassembly is completed, control the clamping device to correct the position of the housing 1 according to the corrected clamping position.

[0131] The disassembly device is a device for separating and disassembling the USB interface housing 1 and the base 2. The disassembly device is controlled to separate and disassemble the USB interface housing 1 and the base 2, and after the disassembly is completed, the clamping device is controlled to correct the position of the housing 1 to correct the clamping position for subsequent steps.

[0132] Step 705: After the position is corrected, the press equipment is controlled to re-press the housing 1 and the base 2 to complete the installation.

[0133] After the position of the housing 1 is corrected, the press equipment is controlled to re-press the housing 1 and the base 2 to complete the installation.

[0135] The post-pressing image information refers to the image of the USB interface after the housing 1 and the base 2 are re-pressed. The post-pressing image information is obtained by taking a photo with a camera. When the housing 1 and the base 2 are re-pressed, the post-pressing image information needs to be obtained for subsequent steps.

[0136] Step 801: When the post-compression image information contains shell crack features, the shell crack position and shell crack size are determined according to the post-compression image information, the shell crack features and a preset reference object.

[0137] The reference object refers to an object used to assist in comparing the position and size of the shell crack.

The crack database is a manually set database and will not be described in detail here.

[0139] When the post-pressing image information contains shell crack features, it means that when the shell 1 and the base 2 are re-pressed, cracks appear in the shell 1, and the shell crack position and shell crack size need to be matched for subsequent steps.

[0141] The snap-in position refers to the position after the snap-in slot 5 on the housing 1 and the snap-in buckle 6 on the base 2 snap into each other. The snap-in position is set in advance by a person skilled in the art and will not be described in detail here. The snap-in image information refers to the image at the snap-in position. The snap-in image information is obtained by taking a photo with a camera. When the position of the housing crack is consistent with the snap-in position, it means that the crack is located at the snap-in position and the snap-in image information needs to be obtained for subsequent steps.

[0142] Step 803: When the snap-fit ​​image information contains a preset snap feature, determine the amount of repair material according to the shell crack size.

[0143] The buckle feature refers to the feature of the buckle 6 on the base 2. The buckle feature 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 crack on the shell 1.

[0146] The repair device is a device used to repair a cracked shell 1. The repair device is controlled to repair the crack position of the shell with the amount of repair material.

[0147] Step 805: When the snap-on image information does not contain a preset snap-on feature, an interface abnormality prompt is reported.

[0148] The interface abnormality prompt refers to a prompt issued when the buckle 6 on the base 2 falls off. The interface abnormality prompt is set in advance by a person skilled in the art and will not be described in detail here. When the buckle feature is not included in the snap connection image information, it means that the buckle 6 on the base 2 has fallen off and the interface abnormality prompt needs to be reported.
