Description

Technical Field

[0001] The invention relates to the field of automobile parts, and in particular to a quality detection method, system and terminal for a USB interface. Background Art

[0002] The USB interface is mainly used in cars and has charging and data transmission functions.

[0003] Most users rely heavily on the car's USB port while driving. The USB port is used to charge mobile devices and connect data. If the battery of the mobile phone is low in the car, the mobile phone can be charged by plugging the data cable into the USB port. The USB port includes a circuit PCB in the middle, a base for mounting the PCB board, and an outer cover, wherein the outer cover has a buckle that is engaged with a block on the base.

[0004] If the USB interface on the car fails, it will cause great inconvenience to the user. In order for the USB interface on the car to work stably and reliably, the components need to be inspected to determine whether the snap-on connection is complete. Judging whether it is complete with the naked eye is prone to inspection errors and consumes manpower and time. Summary of the invention

[0005] In order to automatically detect a USB interface, improve efficiency and reduce errors, the present invention provides a quality detection method, system and terminal for a USB interface.

[0006] In a first aspect, the present invention provides a method for detecting the quality of a USB interface, which adopts the following technical solution: A quality detection method for a USB interface, comprising: Acquire outer cover detection information of the outer cover and base detection information of the base in a preset detection area, and define the base detection information or the outer cover detection information as shell detection information; Determine the model information from a preset model database according to the shell detection information; Determine the lighting position and lighting brightness value according to the model information; According to the lighting position, the preset lighting device is controlled to light up with the light brightness value to obtain lighting detection information; Determine the reference transmittance based on the model information; Obtaining light transmittance from a preset light transmittance database according to light detection information; Determine whether the light transmittance is consistent with the reference transmittance; If the light transmittance is consistent with the reference transmittance, the light transmittance test is completed; If the light transmittance is inconsistent with the reference transmittance, the abnormal position is marked from the shell detection information; Determine the missing material shape information based on the shell detection information corresponding to the abnormal position; According to the shape information of the missing material, the preset material replenishing device is controlled to produce the corresponding material replenishing block; According to the abnormal position and the filling block, the filling block is repaired to the corresponding outer cover or base by a preset filling method.

[0007] By adopting the above technical scheme, the model information is determined by the shell detection information to clarify the reference transmittance, and the light transmittance is obtained according to the light detection information. When the two are inconsistent, it is determined that there are bubbles, and a patch block is made based on this to repair them, so as to effectively check the problems with the outer cover and the base and carry out targeted repairs, ultimately ensuring the integrity of the outer cover and the base, automatically detecting the USB interface, improving efficiency and reducing errors.

[0008] Optional methods for verifying missing material shape information include: Determine whether the shell detection information includes a preset external opening feature; If the shell detection information includes an outer opening feature, determine whether the cross-sectional area corresponding to the outer opening feature is smaller than the cross-sectional area corresponding to the missing material shape information; If the cross-sectional area corresponding to the external opening feature is not less than the cross-sectional area corresponding to the missing material shape information, the verification is completed; If the cross-sectional area corresponding to the outer opening feature is smaller than the cross-sectional area corresponding to the missing material shape information or the shell detection information does not include the outer opening feature, the opening shape information is determined according to the missing material shape information, and the missing material shape information is updated according to the opening shape information; According to the opening shape information, a preset cutting device is controlled to perform cutting and removal.

[0009] By adopting the above technical solution, when the shell detection information contains the outer opening feature, the shape and cross-sectional area of ​​the filling block are determined, so as to perform the repair. When the shell detection information does not contain the outer opening feature, the opening shape information is determined and updated according to the missing material shape information, and then the cutting device is controlled to perform cutting and removal accordingly, so as to perform quality inspection and verification on the relevant features of the outer cover, and the non-compliant parts are cut to ensure that the whole meets the quality standards.

[0010] Optionally, after the patch block is repaired to the corresponding outer cover, it is tested using a preset flexibility test method, and the flexibility test method includes: Determine the fixed point, the bending point, and the bending distance according to the model information; The outer cover is fixed according to the fixed point, the outer cover is bent according to the bending point and the bending distance value, and a bending detection image of the outer cover is obtained; Determine a reference bending image based on the model information; Determining whether the bend detection image is consistent with the reference bend image; If the bending detection image is consistent with the reference bending image, the flexibility detection is completed; If the bending detection image is inconsistent with the reference bending image, determining whether there are abnormal features in the bending detection image; If there are abnormal features in the bending detection image, the outer cover will be rejected; If there is no abnormal feature in the bending detection image, determine the warping distance value of the abnormal position according to the bending detection image; Determine whether the lift distance value is less than 0; If the warping distance value is less than 0, the preset material replenishing device is controlled according to the missing material shape information to manufacture the corresponding material replenishing block, and the material replenishing block is repaired to the outer cover according to the abnormal position and the material replenishing block by the preset material replenishing method; If the warping distance value is not less than 0, the filling block is pulled out according to the abnormal position, and the filling block is repaired to the outer cover according to the abnormal position and the filling block by a preset filling method.

[0011] By adopting the above technical solution, the outer cover is fixed at a fixed point according to the model information, and the outer cover is bent according to the bending point and the bending distance value, so as to detect whether the flexibility is normal. If there are abnormal characteristics, it means that there is still a problem after the repair, and the outer shell is removed. If the repaired block falls off, the patch block is repaired. If the repaired block is loose and warped, it is pulled out and repaired again, so as to complete the quality inspection of the flexibility and appearance of the outer cover.

[0012] Optionally, also include: Obtaining PCB image recognition information of the PCB board in a preset recognition area; Select component images from the PCB image recognition information box according to preset component features; Determine the reference component position, reference component height and driving distance according to the model information; Obtain component positions according to component images; Determine whether the component position is consistent with the reference component position; If the component position is inconsistent with the reference component position, the PCB board is clamped to the preset modification area; If the component position is consistent with the reference component position, the component height is determined based on the component image; Determine whether the component height is consistent with the reference component height; If the component height is inconsistent with the reference component height, clamp the PCB board to the preset modification area; If the component height is consistent with the reference component height, push the PCB into the base with the pushing distance.

[0013] By adopting the above technical solution, the component position is compared with the reference component position, and the component height is compared with the reference component height. If there is inconsistency after comparison, it means that the installation position or height is incorrect. The PCB boards that do not meet the requirements will be screened out and sent for repair. Those that meet the requirements will be pushed according to the specified distance for the next step, thereby improving the accuracy of installation and improving the installation quality of the USB interface.

[0014] Optionally, after the PCB board is pushed into the base with a pushing distance, the following steps are also included: Determine the snap-in distance and reference push force value based on the model information; Determine the pre-clamping distance according to the clamping distance; According to the pre-clamping distance, the housing is controlled to be pushed into the base and the pushing force value is obtained; Determine whether the push force value is consistent with the reference push force value; If the push force value is consistent with the reference push force value, the housing is further pushed toward the base according to the clamping distance control to complete the clamping; If the push force value is greater than the reference push force value, the grinding position is determined according to the base detection information and the preset reference mark position, the force difference between the push force value and the reference push force value is calculated, the bevel cut value is determined according to the force difference, and the bevel cut value is cut according to the grinding position to complete the adjustment; If the push force value is less than the reference push force value, the force difference between the push force value and the reference push force value is calculated, and the bevel increase value is determined according to the force difference, and the bevel increase value is increased according to the grinding position to complete the adjustment; After the adjustment is completed, the housing is controlled to be pushed toward the base according to the pre-clamping distance and the pushing force value is re-obtained.

[0015] By adopting the above technical solution, if the push-in force value is consistent with the reference push-in force value, it means that the force during pushing meets the requirements and can be successfully pushed in. If it is inconsistent, it means that the clamping part of the base is too high or too low. In order to enable smooth clamping, grinding or bevel thickening is performed according to actual conditions, which effectively reduces the quality problems of loose connection and unqualified assembly during clamping.

[0016] Optionally, after the card connection is completed, the following steps may also be included: Determine the suction force, suction position and pulling force according to the model information; The outer cover and the base are fixed according to the inhalation position, the inhalation force is used to fix the outer cover and the base, and the outer cover and the base are controlled to move away from each other according to the pulling force and the pulling image information is obtained; Determine whether the pulled apart image information contains a preset cracking feature; If the pulled-apart image information does not contain crack features, the crack detection is completed; If the pulled-open image information contains cracking features, the outer cover is separated from the base by a preset dismantling method, and the outer cover and the base are clamped to a preset waste area, and the PCB board is clamped to a preset placement area.

[0017] By adopting the above technical solution, after fixing the outer cover and the base respectively according to the suction position and the suction force, the outer cover and the base are moved away from each other by pulling apart. If cracks occur, it means that the quality is not up to standard. In this case, the outer cover and the base are separated and removed and placed in the waste area. The removed PCB board is placed in the placement area for subsequent use to improve product quality.

[0018] Optionally, after the crack detection is completed, it also includes: Determine the baseline looseness value based on the model information; identifying loose values ​​from the pulled apart image information; Determine whether the looseness value is less than the reference looseness value; If the looseness value is less than the reference looseness value, the initial inspection is completed; If the looseness value is not less than the reference looseness value, the repair value is determined according to the looseness value; Matching the corresponding first material patching data according to the repair value, and manufacturing a first material patching sheet according to the first material patching data; The outer cover is separated from the base by a preset dismantling method, and the first patch piece is repaired to a preset repair area on the outer cover until the looseness value is less than the reference looseness value to complete the repair.

[0019] By adopting the above technical solution, the looseness value of the clamping part is obtained by identification. If the looseness value is less than the reference looseness value, it means there is no looseness. If it is not less than the reference looseness value, it means there is looseness. The first filling material data is obtained according to the actual situation, and the first filling material piece is manufactured. After the outer cover is separated from the base, the first filling material piece is repaired to the preset repair area of ​​the outer cover to prevent malfunctions or safety hazards caused by loose defects, thereby improving the overall reliability and stability of the product.

[0020] Optionally, the looseness value is less than the reference looseness value and further includes: Determine the blowing force, blowing angle, blowing position and reference sound information according to the model information; The preset blowing device is controlled to adjust according to the blowing position and blowing angle, and the blowing device is controlled to blow according to the blowing intensity; When blowing, obtain sound detection information; Determine the gap location based on the sound detection information; determining whether the sound detection information is consistent with the reference sound information; If the sound detection information is consistent with the reference sound information, the detection is completed; If the sound detection information is inconsistent with the reference sound information, determining the second feeding data according to the sound detection information; A corresponding second patch piece is manufactured according to the second patch data, and the second patch piece is repaired to the gap position until the sound detection information is consistent with the reference sound information.

[0021] By adopting the above technical solution, when the blowing device is controlled to blow air, sound detection information is obtained. When the sound detection information is inconsistent with the reference sound information, it means that there is still a gap. According to the second filling material data obtained according to the actual situation, a second filling material piece is produced, and the second filling material piece is repaired to the gap position, so as to achieve the effect of detecting and repairing the sealing of the product structure to ensure the quality, ensure that the product meets the corresponding quality standards, and avoid sealing problems caused by gaps.

[0022] In a second aspect, the present application provides a USB interface quality detection system, which adopts the following technical solution: A quality detection system for a USB interface, comprising: An acquisition module is used to acquire cover detection information, base detection information, illumination detection information, missing material shape information, opening shape information, PCB image recognition information, sound detection information, opening image information, and model information; A memory, used to store a program of the above-mentioned USB interface quality detection method; The processor is used to load the program stored in the memory.

[0023] By adopting the above technical solution, data is acquired through the acquisition module, model information is determined through shell detection information to clarify the benchmark transmittance, and light transmittance is obtained according to light detection information. When the two are inconsistent, it is determined that there are bubbles, and a patch block is made based on this to repair them, thereby effectively troubleshooting problems with the outer cover and the base and performing targeted repairs, ultimately ensuring the integrity of the outer cover and the base, automatically detecting the USB interface, improving efficiency, and reducing errors.

[0024] In a third aspect, the present application provides an intelligent terminal, including a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute the above-mentioned USB interface quality detection method.

[0025] By adopting the above technical solution, a computer program that can be loaded by a processor and execute the quality inspection of the above-mentioned USB interface is stored in the memory to obtain model information, thereby determining the reference light transmittance.

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] A quality inspection method for a USB interface, which uses light to understand the light transmittance of the product, and then determines whether it needs to be cut according to the bubble situation after light transmission, and finally repairs it with a patch block. After the repair, the flexibility is tested by bending to further understand the situation of the patch block. The height of the components on the PCB board 3 is tested to understand the installation situation of the PCB board 3. The outer cover 1 and the base 2 are clamped together to understand the overall matching situation; then the outer cover 1 and the base 2 are pulled apart to understand the looseness.

[0033] Reference Figure 1The USB interface of the present application comprises an outer cover 1, a base 2 and a PCB board 3. The outer cover 1 is provided with a buckle 4, and the base 2 is provided with a block 5. The buckle 4 and the block 5 are fixed to each other. The PCB board 3 is installed in the base 2 and fixed by the outer cover 1.

[0034] Reference Figure 2 The present application embodiment discloses a USB interface quality detection method, comprising the following steps: Step 100: Acquire outer cover detection information of the outer cover 1 and base detection information of the base 2 in a preset detection area, and define the base detection information or the outer cover detection information as shell detection information.

[0035] The inspection area is the area where the components of the USB interface are inspected. The outer cover inspection information is an image photo of the outer cover 1. The base inspection information is an image photo of the base 2. The shell inspection information is an image photo of the outer cover 1 and the base 2.

[0036] The outer cover detection information of the outer cover 1 and the base detection information of the base 2 are acquired through a preset camera, and the base detection information or the outer cover detection information is defined as the shell detection information.

[0037] Step 101: Determine model information from a preset model database according to shell detection information.

[0038] The model database stores model information of different USB interfaces and features corresponding to the model information. The features are obtained from image photos. Therefore, after the shell detection information is input into the model database, the model information corresponding to the shell detection information can be obtained from the model database.

[0039] Step 102: Determine the lighting position and the light brightness value according to the model information.

[0040] The illumination position is the position where the light is irradiated to the outer cover 1 or the base 2. In this application, it is the inside of the outer cover 1 and the base 2. The image is obtained by irradiating from the inside to the outside. The light brightness value is the intensity of the light. Different model information has different structures and thicknesses, so it corresponds to different illumination positions and light brightness values, which are pre-set by the staff and will not be repeated here.

[0041] The illumination device is a lamp capable of adjusting light. By inputting known model information, the illumination position and light brightness value corresponding to the model information are obtained.

[0042] Step 103: Control a preset lighting device to light up according to the lighting position and the light brightness value to obtain lighting detection information.

[0043] The light detection information is the photos of different light transmittances collected during the lighting process. The lighting device is controlled to light up according to the light brightness value according to the lighting position, and the light detection information is obtained through the camera.

[0044] Step 104: Determine a reference light transmittance according to the model information.

[0045] The reference transmittance is determined based on the model information. Different model information corresponds to different reference transmittances, which are pre-set by the staff and will not be elaborated here.

[0046] Step 105: Obtaining light transmittance from a preset light transmittance database according to the light detection information.

[0047] The light transmittance is the light transmittance index of the base 2 or the outer cover 1 in the photo. The light transmittance index at the same position in the present application is the same. Once a defect occurs, the light transmittance index will change and be captured by the camera.

[0048] The light transmittance database has the ability to identify the light transmittance indicators in the photos corresponding to the light detection information. The light transmittance database is trained through a convolutional neural network model, and the preset sample set is input for learning. The test set is then tested and identified to select a model with a screening rate greater than 99%. The staff will adjust it according to the actual situation, which will not be elaborated here.

[0049] By inputting the light detection information into the light transmittance database, the corresponding light transmittance is obtained from the light transmittance database.

[0050] Step 106: Determine whether the illumination transmittance is consistent with the reference transmittance.

[0051] Determine whether the light transmittance is consistent with the reference transmittance, so as to determine whether the thickness of the USB interface is defective.

[0052] Step 1060: If the illumination transmittance is consistent with the reference transmittance, the transmittance detection is completed.

[0053] If the light transmittance is consistent with the reference transmittance, it means that the thickness of the USB interface is normal, and the light transmittance test is completed.

[0054] Step 1061: If the illumination transmittance is inconsistent with the reference transmittance, the abnormal position is marked from the shell detection information.

[0055] If the light transmittance is inconsistent with the reference transmittance, it means that the thickness is abnormal, and the abnormal position is marked from the photo corresponding to the shell detection information. The abnormal position is the position where the light transmittance is different from the reference transmittance.

[0056] Step 107: Determine the missing material shape information according to the shell detection information corresponding to the abnormal position.

[0057] The missing material shape information is the three-dimensional data of the missing material part at the abnormal position. The three-dimensional data corresponding to the abnormal position is obtained from different angles through the preset camera to obtain the missing material shape information. The acquisition method is set by the staff according to the actual situation and will not be described here. That is, the missing images obtained from different angles are different, and the missing material shape information is obtained by integration.

[0058] Step 108: Control the preset material replenishing device according to the missing material shape information to produce the corresponding material replenishing block.

[0059] The material-replenishing device is a 3D printer, which is used to manufacture a material-replenishing block. The material-replenishing block is a material-replenishing block manufactured to repair an abnormal position. The material-replenishing device is controlled according to the material-deficient shape information to manufacture the corresponding material-replenishing block.

[0060] Step 109: repairing the filling block to the corresponding outer cover 1 or base 2 by a preset filling method according to the abnormal position and the filling block.

[0061] The patching block is repaired according to the abnormal position by a patching method. The patching method is to use hot melt repairing to heat the abnormal position of the outer cover 1 or the base 2 and the corresponding part of the patching block to melt the surface, and then fit the patching block to the abnormal position, and finally grind the excess part to make it smooth.

[0062] According to the abnormal position and the filling block, the filling block is repaired to the corresponding outer cover 1 or base 2 by a filling method, thereby completing the repair.

[0063] Reference Figure 3 The verification method of the missing material shape information includes the following steps: Step 200: Determine whether the outer cover detection information contains a preset outer opening feature.

[0064] The outer opening feature is a feature of a notch exposed on the surface of the outer cover 1 or the base 2. It is determined whether the outer cover detection information includes a preset outer opening feature, thereby determining whether the surface of the outer cover 1 or the base 2 has a notch.

[0065] The distance sensor is used to measure the distance of the surface, so as to understand whether the abnormal position in the outer cover detection information is on the surface. It is also possible to use the image recognition method to determine whether the gap is on the outside and determine whether the abnormal position is on the surface through image comparison.

[0066] Step 2000: If the outer cover detection information includes an outer opening feature, determine whether the cross-sectional area corresponding to the outer opening feature is smaller than the cross-sectional area corresponding to the missing material shape information.

[0067] The cross-sectional area corresponding to the external opening feature is the diameter area of ​​the surface. The cross-sectional area corresponding to the missing material shape information is the diameter area inside the notch.

[0068] If the outer cover detection information includes an outer opening feature, it means that there is a gap on the surface of the outer cover 1 or the base 2. Then, it is determined whether the cross-sectional area corresponding to the outer opening feature is smaller than the cross-sectional area corresponding to the missing material shape information, so as to determine whether cutting is required.

[0069] Step 20000: If the cross-sectional area corresponding to the outer opening feature is not less than the cross-sectional area corresponding to the missing material shape information, the verification is completed.

[0070] If the cross-sectional area corresponding to the outer opening feature is not less than the cross-sectional area corresponding to the missing material shape information, it means that the filling block can be put in, and the verification is completed.

[0071] Step 20001: If the cross-sectional area corresponding to the outer opening feature is smaller than the cross-sectional area corresponding to the missing material shape information or the outer cover detection information does not include the outer opening feature, the opening shape information is determined according to the missing material shape information, and the missing material shape information is updated according to the opening shape information.

[0072] The feature of the outer opening is not included, indicating that there are bubbles inside and it is hollow. The opening shape information is the three-dimensional data that needs to be cut, and the filling block is placed in after cutting.

[0073] If the cross-sectional area corresponding to the outer opening feature is smaller than the cross-sectional area corresponding to the missing material shape information or the outer cover detection information does not contain the outer opening feature, it means that the filling block cannot be placed in. Then, the maximum cross-sectional area is obtained according to the missing material shape information, thereby obtaining the opening shape information, and updating the missing material shape information according to the opening shape information.

[0074] Step 201: Controlling a preset cutting device to perform cutting and removal according to the opening shape information.

[0075] The cutting device is a tool controlled by a manipulator, and the cutting device is controlled to cut and remove abnormal positions according to the opening shape information.

[0076] Reference Figure 4 , the flexibility detection method comprises the following steps: Step 300: Determine the fixing point, the bending point and the bending distance value according to the model information.

[0077] Different USB interfaces have different model information, and different model information has different fixed points, bending points, and bending distance values. The fixed point is a position selected on the outer cover 1 that can stably fix the outer cover 1. The bending point is a bending position where a bending force is subsequently applied. The bending distance value is the distance range moved during the bending process.

[0078] Determine the fixed point, bend point, and bend distance values ​​based on the model information.

[0079] Step 301: fix the outer cover 1 according to the fixed points, bend the outer cover 1 according to the bending points and the bending distance values, and obtain a bending detection image of the outer cover 1.

[0080] The bending detection image is a picture detected by the camera when bending. The outer cover 1 is fixed according to the fixed point, the outer cover 1 is bent according to the bending point and the bending distance value, and the bending detection image of the outer cover 1 is obtained. The image records the morphological changes of the surface of the outer cover 1 to know whether cracks or deformations occur.

[0081] Step 302: Determine a reference bending image according to the model information.

[0082] Different USB interfaces have different model information, and different model information has different reference bending images after being bent. The data is stored for subsequent use.

[0083] By understanding the model information, the corresponding reference bending image can be obtained.

[0084] Step 303: Determine whether the bend detection image is consistent with the reference bend image.

[0085] It is determined whether the bending detection image is consistent with the reference bending image, so as to determine whether the repaired part is abnormal during bending. The repaired part is the outer cover 1 or the base 2 with an abnormal position.

[0086] Step 3030: If the bending detection image is consistent with the reference bending image, the flexibility detection is completed.

[0087] If the bending test image is consistent with the reference bending image, it means that the repaired parts are normal when bending, and the flexibility test is completed.

[0088] Step 3031: If the bending detection image is inconsistent with the reference bending image, determine whether there are abnormal features in the bending detection image.

[0089] The abnormal feature is a crack or deformation feature. If the bending test image is inconsistent with the reference bending image, it means that the repaired part is abnormal during bending, and then it is determined whether there is an abnormal feature in the bending test image.

[0090] Step 30310: If there are abnormal features in the bending detection image, the outer cover 1 is discarded.

[0091] If there are abnormal features in the bending detection image, it means that the repaired part is cracked or deformed, then the repaired part will be clamped and removed by a preset robot.

[0092] Step 30311: If there is no abnormal feature in the bending detection image, determine the lift distance value of the abnormal position based on the bending detection image.

[0093] The warping distance value is the distance that the repair block warps out. If there is no abnormal feature in the bending detection image, it means that there is no cracking or deformation. The abnormal position in the bending detection image is detected by the distance sensor to output the warping distance value.

[0094] Step 304: Determine whether the lift distance value is less than 0.

[0095] Determine whether the lift distance value is less than 0 to determine whether the filling block has fallen.

[0096] Step 3040: If the lift distance value is less than 0, the preset material replenishing device is controlled according to the missing material shape information to produce the corresponding material replenishing block, and the material replenishing block is repaired to the outer cover 1 according to the abnormal position and the material replenishing block by the preset material replenishing method.

[0097] If the lift distance value is less than 0, it means that the filling block has fallen, and the preset filling device is controlled again according to the missing material shape information to produce the corresponding filling block, and the filling block is repaired to the outer cover 1 according to the abnormal position and the filling block using the preset filling method.

[0098] Step 3041: If the warping distance value is not less than 0, the filling block is pulled out according to the abnormal position, and the filling block is repaired to the outer cover 1 according to the abnormal position and the filling block by a preset filling method.

[0099] If the lifting distance value is not less than 0, it means that the filling block is lifted, then the preset manipulator is controlled to pull out the filling block according to the abnormal position, and repair the filling block to the outer cover 1 according to the abnormal position and the filling block by the preset filling method. The manipulator is a preset device, which is preset by the operator.

[0100] If the lift distance value is equal to 0, it means that the bending detection image is consistent with the reference bending image, so no judgment is needed.

[0101] Reference Figure 5 , the component detection method includes the following steps: Step 400: Acquire PCB image recognition information of the PCB board 3 in a preset recognition area.

[0102] The identification area is the area to be identified by the PCB board 3. The PCB image identification information is the image information obtained by identifying the identification area through the camera.

[0103] Step 401: Select a component image from a PCB image recognition information frame according to preset component features.

[0104] The component features are preset data, and the component features are appearance features of the components. The component features in the PCB image recognition information are framed and selected according to the component features, thereby obtaining a component image.

[0105] Step 402: Determine the reference component position, reference component height, and driving distance according to the model information.

[0106] Different types of USB interfaces correspond to different PCB boards 3 , and different PCB boards 3 have different components, so the corresponding reference component positions, reference component heights, and pushing distances of the PCB boards 3 are also different.

[0107] Therefore, different model information is used to determine the corresponding reference component position, reference component height and pushing distance.

[0108] The reference component position is the accurate installation position of the component on the PCB board 3. The reference component height is the vertical height value of the component in a normal installation state. The push distance is the distance parameter required to move the PCB board 3 to be accurately installed in the base 2.

[0109] The reference component position, reference component height and pushing distance are collected in advance and set by those skilled in the art, and will not be elaborated here.

[0110] Step 403: Obtain component locations according to the component images.

[0111] The component position is the real-time position of the component on the PCB board 3.

[0112] Since the shape of the PCB board 3 is fixed and uniform and at least three known positions can be pre-marked, the positions of the components installed on the PCB board 3 are also known.

[0113] Step 404: Determine whether the component position is consistent with the reference component position.

[0114] Determine whether the component position is consistent with the reference component position, so as to determine whether the component position is accurate.

[0115] Step 4040: If the component position is inconsistent with the reference component position, clamp the PCB board 3 to a preset modification area.

[0116] The modification area is the area where the USB parts are adjusted and modified. The staff re-fixes the components on the PCB board 3 by welding.

[0117] If the component position is inconsistent with the reference component position, it means that the component position is inaccurate, which in this embodiment refers to incorrect installation position, and the PCB board 3 is clamped to the modification area by a preset manipulator. The manipulator is a preset device, which is preset by the operator.

[0118] Step 4041: If the component position is consistent with the reference component position, the component height is determined based on the component image.

[0119] If the component position is consistent with the reference component position, it means that the component position is accurate. Then, the component height is determined based on the component image and component position.

[0120] Step 405: Determine whether the component height is consistent with the reference component height.

[0121] Determine whether the component height is consistent with the reference component height, thereby determining whether the component height is accurate.

[0122] Step 4050: If the component height is inconsistent with the reference component height, clamp the PCB board 3 to a preset modification area.

[0123] If the height of the component is inconsistent with the height of the reference component, it means that the height of the component is abnormal, then the PCB board 3 is clamped to the modification area, and the staff re-fixes the components on the PCB board 3 by welding.

[0124] Step 4051: If the component height is consistent with the reference component height, the PCB board 3 is pushed into the base 2 at a pushing distance.

[0125] If the component height is consistent with the reference component height, it means that the component height is normal, and then the PCB board 3 is pushed into the base 2 by the pushing distance.

[0126] After the PCB board 3 is pushed into the base 2 by a pushing distance, the clamping method includes the following steps: Step 500: Determine the engagement distance and the reference push force value according to the model information.

[0127] Different types of USB interfaces correspond to different card connection distances and reference push force values, which are set in advance by those skilled in the art and will not be described in detail here.

[0128] The clamping distance is the displacement distance of the housing pushed into the base 2. The reference push force value is the reasonable force that should be applied during the clamping process.

[0129] Step 501: Determine a pre-clamping distance according to the clamping distance.

[0130] The pre-engagement distance is the distance before the final engagement position is reached. At this time, the buckle 4 and the clamping block 5 are not in a completely engaged state, and the buckle 4 is in a state of being about to engage above the clamping block 5.

[0131] Different model information corresponds to different clamping distances and pre-clamping distances, and the clamping distances correspond to the pre-clamping distances one by one.

[0132] Step 502: Control the housing to be pushed toward the base 2 according to the pre-clamping distance and obtain the pushing force value.

[0133] The push force value is the force value of pushing the housing, and the push force value is obtained by a force sensor in a preset cylinder. The cylinder controls the housing to be pushed toward the base 2.

[0134] The cylinder is controlled to push the housing toward the base 2 according to the pre-clamping distance, and the pushing force value is obtained through the force sensor in the cylinder.

[0135] Step 503: Determine whether the pushing force value is consistent with the reference pushing force value.

[0136] It is determined whether the pushing force value is consistent with the reference pushing force value, so as to determine whether there is a problem between the buckle 4 and the clamping block 5 .

[0137] Step 5030: If the pushing force value is consistent with the reference pushing force value, the housing is controlled to continue to be pushed toward the base 2 according to the locking distance to complete the locking.

[0138] If the pushing force value is consistent with the reference pushing force value, it means that there is no problem between the buckle 4 and the clamping block 5, and the clamping can be successfully connected by pushing with the reference pushing force value.

[0139] Step 5031: If the pushing force value is greater than the reference pushing force value, the grinding position is determined according to the base detection information and the preset reference mark position, the force difference between the pushing force value and the reference pushing force value is calculated, the bevel cutting value is determined according to the force difference, and the bevel cutting value is cut according to the grinding position to complete the adjustment.

[0140] The grinding position is the clamping point when the clamping block 5 is clamped. The force difference is the difference between the push force value and the reference push force value. The bevel cut value is the amount of cutting and grinding of the bevel at the clamping point when the clamping block 5 is clamped, and different force differences correspond to different bevel cut values.

[0141] If the pushing force value is greater than the reference pushing force value, it means that the clamping point of the clamping block 5 is too steep. The force difference between the pushing force value and the reference pushing force value is calculated, and the corresponding bevel resection value is obtained according to the force difference. The bevel resection value is used according to the grinding position and the preset grinding wheel machine to perform grinding and resection to complete the adjustment. The grinding wheel machine is preset by the operator.

[0142] Step 5032: If the pushing force value is less than the reference pushing force value, calculate the force difference between the pushing force value and the reference pushing force value, determine the bevel increase value based on the force difference, and increase the bevel increase value based on the grinding position to complete the adjustment.

[0143] The increased value of the bevel is the amount of increase in the bevel cut at the clamping position when the base 2 is clamped.

[0144] If the pushing force value is less than the reference pushing force value, it means that the clamping point of the clamping block 5 is too slow. By calculating the force difference between the pushing force value and the reference pushing force value, the corresponding slope increase value is obtained according to the force difference. According to the grinding position, the material is repaired with the slope increase value through a preset repairer, thereby increasing the slope to complete the adjustment. The repairer is preset by the operator.

[0145] Step 504: After the adjustment is completed, the housing is controlled to be pushed toward the base 2 according to the pre-clamping distance and the pushing force value is re-obtained.

[0146] After the adjustment operation is completed, it is necessary to perform the pushing operation again and obtain the pushing force value to verify whether the adjustment measure is effective so that the cooperation between the housing and the base 2 reaches a state that meets the standard requirements.

[0147] The USB interface card connection quality detection method includes the following steps: Step 600: Determine the suction force, suction position and pulling force according to the model information.

[0148] The suction force is the force of suction applied to the outer cover 1 and the base 2 by the preset suction cup when the outer cover 1 and the base 2 are fixed. The suction position is the part selected on the surface of the outer cover 1 and the base 2 and used to connect the suction device and apply the suction effect. The pulling force is the external force applied to the outer cover 1 and the base 2 to make them move away from each other when the outer cover 1 and the base 2 are separated.

[0149] Different types of USB interfaces correspond to different suction forces, suction positions and pulling forces.

[0150] Step 601: fix the outer cover 1 and the base 2 according to the inhalation position, fix them according to the inhalation strength, control the outer cover 1 and the base 2 to move away from each other according to the pulling strength and obtain pulling image information.

[0151] The pulling apart image information is obtained by shooting the outer cover 1 and the base 2 from multiple angles through a camera, recording the visual information of the appearance and connection parts of the two. The suction device is used to fix the outer cover 1 and the base 2 according to the suction position, and the suction is fixed according to the suction force. According to the pulling apart force, the preset cylinder is controlled to move the outer cover 1 and the base 2 away from each other and obtain the pulling apart image information. The cylinder drives the suction device to move. In this application, the suction device is a matching component of a suction cup and an air pump, which is set by the staff according to the actual situation and will not be elaborated here.

[0152] Step 602: Determine whether the pulled-open image information contains a preset cracking feature.

[0153] The cracking feature is a feature of cracks or damages in the connection between the buckle 4 and the block 5. It is determined whether the pulled-apart image information contains a preset cracking feature, thereby determining whether there is a cracking problem between the buckle 4 and the block 5.

[0154] Step 6020: If the pulled-open image information does not contain crack features, crack detection is completed.

[0155] If the pulled-apart image information does not contain crack features, it means that no cracks have occurred, and the crack detection is completed.

[0156] Step 6021: If the pulled-open image information contains crack features, the outer cover 1 and the base 2 are separated by a preset dismantling method, and the outer cover and the base 2 are clamped to a preset waste area, and the PCB board 3 is clamped to a preset placement area.

[0157] The removal method is to control the robot to insert the preset removal piece into the removal opening 6, so as to lift up and complete the removal of the housing and the base 2. If the pull-open image information contains cracking features, it means that there is a problem with the connection between the housing and the base 2, then the outer cover 1 and the base 2 are separated by the removal method, and the preset robot is controlled to clamp the PCB board 3 to the preset placement area.

[0158] The USB interface card connection quality detection method includes the following steps: Step 700: Determine a reference looseness value according to model information.

[0159] The reference looseness value is the maximum looseness value allowed under ideal conditions between the outer cover 1 and the base 2. The reference looseness value is determined according to the model information, and different models of USB interfaces correspond to different reference looseness values.

[0160] Step 701: Identify the looseness value from the pulled-apart image information.

[0161] The looseness value is the actual looseness value of the outer cover 1 and the base 2. The looseness value, that is, the distance between the two in the pulled apart state, is identified from the pulled apart image information by a preset camera, and the looseness value is obtained by synchronous calculation through a preset reference coordinate.

[0162] Step 702: Determine whether the looseness value is less than a reference looseness value.

[0163] It is determined whether the looseness value is less than the reference looseness value, thereby determining whether the looseness between the outer cover 1 and the base 2 meets the requirements.

[0164] Step 7020: If the looseness value is less than the reference looseness value, the initial inspection is completed.

[0165] If the looseness value is less than the reference looseness value, it means that the looseness between the outer cover 1 and the base 2 meets the quality standard, and the initial inspection is completed.

[0166] Step 7021: If the loose value is not less than the reference loose value, determine the repair value according to the loose value.

[0167] The repair value is the amount of repair for the loose part. If the loose value is not less than the reference loose value, it means that there is a problem with the looseness of the outer cover 1 and the base 2, and repair is required. The repair value is determined according to the size of the loose value, and different loose values ​​correspond to different repair values.

[0168] Step 703: Match the corresponding first material patching data according to the repair value, and manufacture a first material patching sheet according to the first material patching data.

[0169] The location of the filling material is the preset location of the buckle 4, so the three-dimensional data of the contact surface when the buckle 4 and the block 5 are pulled is known, and only the thickness needs to be obtained to repair. Therefore, the first filling material data, that is, the thickness value, is determined by the repair value.

[0170] The patching piece is a patching piece at the clamping position when the manufactured base 2 is clamped. The patching device is controlled according to the first patching data to manufacture the corresponding patching piece, which is the first patching piece.

[0171] Step 704: Separate the outer cover 1 from the base 2 by a preset disassembly method, and repair the first patch piece to the preset repair area on the outer cover 1 until the looseness value is less than the reference looseness value to complete the repair.

[0172] The repair area is determined according to the specific location and stability of the looseness of the outer cover 1 and the base 2, and is near the connection part or a location that can effectively enhance the tightness of the connection. The outer cover 1 and the base 2 are separated by a dismantling method, and the first patch piece is repaired to the repair area on the outer cover 1 by a repairer. After the repair is completed, the loose value is updated until the loose value is less than the reference loose value to complete the repair. During the repair, the first patch piece is fixed to the buckle 4 by ultrasonic welding.

[0173] The USB interface card connection quality detection method includes the following steps: Step 800: Determine the blowing force, blowing angle, blowing position and reference sound information according to the model information.

[0174] The blowing force is the blowing force of the preset blowing device when performing the blowing operation. The blowing angle is the angle of the blowing device when performing the blowing operation. The blowing position is the clamping point between the outer cover 1 and the base 2. The reference sound information is the sound information generated when the USB interface is in the preset state and the blowing operation is performed according to the standard blowing force, blowing angle and blowing position. Different models of USB interfaces correspond to different blowing forces, blowing angles, blowing positions and reference sound information.

[0175] The blowing device is a combination of an air pump, a connecting pipe and a mouthpiece that can adjust the angle and stably output airflows of different intensities. It is set by the staff according to the actual situation and will not be described in detail here. The preset state is set by the staff according to the actual situation and will not be described in detail here.

[0176] Step 801: Control a preset blowing device to adjust according to the blowing position and blowing angle, and control the blowing device to blow according to the blowing intensity.

[0177] The preset blowing device is controlled to adjust according to the blowing position and blowing angle, and the blowing device is controlled to blow according to the blowing intensity.

[0178] Step 802: Acquire sound detection information during blowing.

[0179] The sound detection information is the friction sound of the airflow when blowing or the sound generated when the airflow passes through the gap. While the blowing device is blowing according to the set parameters, the sound detection information is obtained using an acoustic imager.

[0180] Step 803: Determine whether the sound detection information is consistent with the reference sound information.

[0181] It is determined whether the sound detection information is consistent with the reference sound information to determine whether there is an abnormal gap.

[0182] Step 8030: If the sound detection information is consistent with the reference sound information, the detection is completed.

[0183] If the sound detection information is consistent with the reference sound information, it means there is no gap or the gap is within a reasonable range, and the detection is completed.

[0184] Step 8031: If the sound detection information is inconsistent with the reference sound information, the blowing position is defined as the gap position and the second material replenishment data is determined according to the sound detection information.

[0185] If the sound detection information is inconsistent with the reference sound information, it means that the gap is too large, the blowing position is defined as the gap position, and the corresponding second material replenishment data is matched from the material replenishment database according to the sound detection information.

[0186] The gap conditions of the sounds generated at different angles are pre-stored in the filling material database, and the three-dimensional parameters that need to be thickened are obtained through the gap conditions and the known edges, that is, the second filling material data.

[0187] Step 804: manufacturing a corresponding second patch piece according to the second patch data, and patching the second patch piece to the gap position until the sound detection information is consistent with the reference sound information.

[0188] The material replenishing device is controlled according to the second material replenishing data to manufacture the corresponding second material replenishing piece. The second material replenishing piece is ultrasonically welded to the gap position, and the sound detection information is updated until the sound detection information is consistent with the reference sound information.
