Description

Technical Field

[0001] The present invention relates to the field of automobile shock absorbers, and in particular to a spraying control method, system and intelligent terminal for shock absorbers. Background Art

[0002] Automobile shock absorbers are important parts in the automobile suspension system and are usually installed between the frame and the axle.

[0003] At present, automobile shock absorber technology has become relatively mature, and shock absorbers have been widely used in various models. During the production process of shock absorbers, the shock absorbers are manually inspected by naked eyes to check whether there are any defects. After checking, they are loaded. After loading, the shock absorbers are sprayed with color in a shower-like manner through spraying equipment.

[0004] However, at present, shock absorbers are inspected manually with the naked eye, and it is impossible to check whether the thickness is standard by visual inspection. If the thickness is abnormal during coloring, it will affect the coloring and cause quality problems, which may shorten the life of the shock absorber and even cause safety accidents. There is still room for improvement in product quality inspection. Summary of the invention

[0005] In order to improve the production quality of shock absorbers, the present invention provides a spraying control method, system and intelligent terminal for shock absorbers.

[0006] In a first aspect, the present invention provides a spraying control method for a shock absorber, which adopts the following technical solution:

[0007] A spraying control method for a shock absorber, comprising:

[0008] Obtaining image detection information and ultrasonic detection information in a preset detection area;

[0009] Determine the model information from a preset model database according to the image detection information;

[0010] Determine the thickness reference range according to the model information;

[0011] Obtaining a thickness detection value from a preset thickness neural network model according to ultrasonic detection information;

[0012] Determine whether the thickness detection value falls within the thickness reference range;

[0013] If the thickness detection value falls within the thickness reference range, the detection is completed, and the preset clamping device is controlled to clamp the shock absorber to the preset coloring area for coloring;

[0014] If the thickness detection value does not fall within the thickness reference interval, the abnormal thickness position is marked based on the ultrasonic detection information and repaired using a preset thickness abnormality repair method.

[0015] By adopting the above technical solution, the image detection information and ultrasonic detection information are analyzed to determine the model information, thickness reference range and thickness detection value. Then, whether the thickness is qualified is determined based on whether the thickness detection value is within the thickness reference range. The qualified shock absorbers are automatically tested and transferred to the coloring area for coloring. The abnormal positions of the unqualified shock absorbers are marked and repaired. The automation and precision of the spraying process are realized, which effectively improves the production quality of the shock absorbers.

[0016] Optional thickness abnormality repair methods include:

[0017] Determine abnormal status based on ultrasonic detection information;

[0018] Determine whether the abnormal state is consistent with the preset crack state;

[0019] If the abnormal state is consistent with the crack state, the preset clamping device is controlled to clamp the shock absorber to the preset crack repairing area, and repair it with the preset crack repairing method;

[0020] If the abnormal state is inconsistent with the crack state, determine whether the thickness detection value is less than the minimum value of the thickness reference interval;

[0021] If the thickness detection value is less than the minimum value of the thickness reference interval, the thickness difference is determined based on the thickness detection value and the minimum value of the thickness reference interval;

[0022] Determine whether the thickness difference is within a preset reference repair interval;

[0023] If the thickness difference is within the reference repair interval, the repair value is determined based on the thickness difference;

[0024] Determine cooling value based on repair value;

[0025] Control a preset manufacturing device to manufacture a patch block with a repair value, then control a preset repair device to weld the patch block, and control a preset cooling device to cool it with a cooling value. After the repair is completed, control the clamping device to clamp the shock absorber to a preset quality inspection area to perform inspection with a preset repair quality inspection method;

[0026] If the thickness difference is not within the reference repair interval, a preset clamping device is controlled to clamp the shock absorber to a preset waste area.

[0027] By adopting the above technical solution, the abnormal state is determined based on the ultrasonic detection information, and the abnormal state is analyzed. When the abnormal state is a crack state, it is repaired using a preset crack repair method. When the abnormal state is not a crack state, and the thickness detection value is less than the minimum value of the thickness reference range, the thickness detection value is analyzed with the reference thickness value to determine whether to repair or clamp to the preset waste area, thereby effectively improving the production quality of the shock absorber.

[0028] Optionally, the abnormal thickness repair method also includes:

[0029] If the thickness detection value is not less than the minimum value of the thickness reference interval, the excess height value is determined according to the thickness detection value and the maximum value of the thickness reference interval;

[0040] By adopting the above technical scheme, when the thickness detection value is not less than the minimum value of the thickness reference interval, it is determined whether the abnormal height position falls into the arc state interval, and the straight cutting position and the straight cutting path that do not fall into the interval are cut, and the arc cutting position and the arc cutting path that fall into the interval are cut. After each cutting, the thickness detection value is updated according to the ultrasonic detection information until the updated thickness detection value falls into the thickness reference interval, and then the shock absorber is transferred to the coloring area, thereby realizing accurate processing of different cutting requirements and effectively improving product quality and production efficiency.

[0041] Optional crack repair methods include:

[0049] By adopting the above technical solution, the crack detection information is analyzed to determine the crack value, and the crack value analysis is improved to obtain the crack depth and area, so as to determine the repair parameters, cooling temperature and grinding value. Subsequently, the abnormal thickness position is repaired, cooled and polished in turn, and finally the shock absorber is transferred to the quality inspection area for inspection to ensure the accuracy and standardization of the crack repair and effectively improve the production quality of the shock absorber.

[0050] Optional repair quality testing methods include:

[0051] Determine the impact reference information and the impact detection value according to the model information;

[0052] Controlling a preset impact device to detect the abnormal thickness position with an impact detection value, and simultaneously obtaining quality detection image information in the quality detection area;

[0053] Determine whether the quality inspection image information is consistent with the impact reference information;

[0055] If the quality inspection image information is consistent with the impact reference information, determining whether the quality inspection image information contains a preset crack feature;

[0056] If the quality inspection image information contains a preset crack feature, the crack position and crack value are determined according to the quality inspection image information;

[0058] If the crack value is within the crack repair interval, a repair value is determined according to the crack value, and a preset crack repair device is controlled to repair the crack position with the repair value;

[0059] If the crack value is not within the crack repairing interval, the preset clamping device is controlled to clamp the shock absorber to the preset waste area;

[0060] If the image detection information does not contain the preset crack features, the preset clamping device is controlled to clamp the shock absorber to the preset coloring area for coloring.

[0061] By adopting the above technical scheme, the abnormal thickness position is detected by controlling the impact device and obtaining quality inspection image information, and the quality inspection image information is compared with the impact reference information. When the quality inspection image information is consistent with the impact reference information, it is determined whether it contains preset crack features. For those with crack features, they are repaired or sent to the waste area for processing based on whether the crack value is in the repair range. For those without cracks, they are clamped to the coloring area for coloring, so as to ensure that the quality of the shock absorber after repair meets the standards and effectively improve the production quality of the shock absorber.

[0062] Optionally, controlling a preset clamping device to clamp the shock absorber to a preset coloring area for coloring includes:

[0063] Get the coloring detection information in the coloring area;

[0064] Determine whether the coloring detection information contains preset foreign matter features;

[0065] If the coloring detection information contains foreign matter features, determine the foreign matter value and foreign matter position according to the coloring detection information;

[0066] Determine whether the foreign matter value is within the preset blowing range;

[0067] If the foreign matter value is within the blowing range, the blowing force is determined according to the foreign matter value, and the preset blowing device is controlled to blow air at the foreign matter position with the blowing force until the coloring detection information does not contain foreign matter features;

[0068] If the foreign matter value is not within the blowing range, the foreign matter area is determined based on the coloring detection information;

[0069] Determine the cleaning amount based on the foreign matter value;

[0070] The cleaning force and cleaning time are determined according to the area of ​​the foreign matter and the cleaning amount, and the preset cleaning device is controlled to spray the foreign matter position with the cleaning amount, and the foreign matter position is brushed with the cleaning force and cleaning time until the coloring detection information does not contain the foreign matter characteristics.

[0071] By adopting the above technical solution, by obtaining the coloring detection information of the colored area, it is determined whether there are foreign matter features. When foreign matter features exist, it is determined based on the foreign matter value, and the foreign matter is removed by blowing or cleaning to ensure that the colored area meets the foreign matter-free standard, thereby effectively improving the production quality of the shock absorber.

[0072] Optionally, when controlling a preset clamping device to clamp the shock absorber to a preset coloring area for coloring, the method further includes:

[0073] If the coloring detection information does not contain foreign matter features, the preset spraying device is controlled to spray the shock absorber, and the coloring completion position and the reference coloring value are determined according to the model information;

[0074] Determine the coloring completion value according to the coloring detection information and the rotation completion position;

[0075] Determine whether the reference coloring value is consistent with the coloring completion value;

[0076] If the reference coloring value is consistent with the coloring completion value, the coloring is completed;

[0077] If the reference coloring value is inconsistent with the coloring completion value, the abnormal coloring position is determined according to the coloring detection information;

[0078] Determine whether the abnormal coloring position is within the preset area spraying interval;

[0079] If the abnormal coloring position is not within the preset area spraying interval, the preset coloring method is used for coloring.

[0080] If the coloring abnormal position is within the preset area spraying interval, the coloring abnormal area is determined according to the coloring abnormal position and the coloring detection information;

[0081] Determine the individual spraying direction and amount according to the abnormal coloring position and area;

[0082] Control the preset separate spraying device to spray the abnormal coloring position with a separate spraying direction and a separate spraying amount, and re-acquire the coloring detection information until the reference coloring value is consistent with the coloring completion value, and then the detection is completed.

[0083] By adopting the above technical solution, when the coloring area is detected to have no foreign matter features, the reference coloring value is compared with the coloring completion value. If inconsistency is found, it is determined by the abnormal coloring position whether to directly supplement the color or use the above coloring method to supplement the color, thereby ensuring that the coloring is complete and improving the coloring quality and product qualification rate.

[0084] Optional coloring methods include:

[0085] Controlling a preset clamping device to clamp the shock absorber corresponding to the abnormal coloring position to a preset color-complementing area;

[0086] Get the scan information in the complementary color area;

[0087] Determine the color-complementing area based on the abnormal coloring position and scanning information;

[0088] Determine the amount of complementary color based on the complementary color area;

[0089] Determine the direction of color complementation based on the abnormal coloring position and scanning information;

[0090] Determine the coloring path according to the complementary color direction, complementary color area and scanning information;

[0091] The preset color-complementing device is controlled to perform color-complementing on the abnormally colored position according to the color path and the color-complementing amount.

[0092] By adopting the above technical solution, when the shock absorber reaches the color correction area, scanning information is obtained, and the color correction area, color correction amount, color correction direction and color correction path are determined in combination with the abnormal coloring position, and then the color correction device is controlled to perform color correction to solve the abnormal coloring problem of the shock absorber and improve the production quality of the shock absorber.

[0098] An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and execute the spraying control method of a shock absorber.

[0099] In summary, the present application includes at least one of the following beneficial technical effects:

[0100] 1. By analyzing the thickness of the shock absorber, if the thickness is too thin, a patch block is made for repair. If the thickness is too thick, the abnormal height position is analyzed and a straight cutting path or an arc cutting path is used for cutting, thereby improving the coloring quality and product qualification rate;

[0101] 2. After the shock absorber is repaired, in order to determine whether the quality of the repaired shock absorber meets the standard, the impact device is controlled to perform testing. Those that pass the test are colored, and those that fail the test are clamped to the waste area, thereby improving the coloring quality and product qualification rate;

[0102] 3. After the shock absorber is colored, the base coloring value and the coloring completion value that are inconsistent will be supplemented with color. By analyzing the base coloring value and the coloring completion value, it is determined whether to supplement the color directly in the area or use the above coloring method, thereby improving the coloring quality and product qualification rate.

[0107] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0108] A spraying control method for a shock absorber determines whether the thickness is qualified by determining whether a thickness detection value is within a thickness reference interval, automatically completes detection of qualified shock absorbers and transfers them to a coloring area for coloring, marks abnormal positions of unqualified ones and repairs them with a repair method; the repair method determines whether to continue cutting or repairing according to an abnormal state, and after crack repair, detects according to a repair quality detection method, and enters the coloring stage only after the detection is qualified. When coloring, first detect whether there are foreign objects, and if there are foreign objects, choose to blow or clean to remove them according to the foreign object value, and spray after there are no foreign objects, and compare the reference with the completed coloring value to determine whether the coloring is consistent. If it is inconsistent, determine the coloring strategy according to the abnormal position and area, etc., and complete the coloring after the coloring is completed until the coloring is qualified, thereby improving the coloring quality and product qualification rate.

[0109] Reference Figure 1 , the embodiment of the present application discloses a spraying control method for a shock absorber, which comprises:

[0110] Step 100: Obtain image detection information and ultrasonic detection information in a preset detection area.

[0111] The detection area refers to the area where the thickness of the shock absorber is detected, which is pre-set by the staff. The image detection information refers to the photo of the shock absorber in the detection area, which is obtained through a preset camera. The ultrasonic detection information refers to the information obtained by ultrasonic testing of the shock absorber in the detection area, which is obtained by an ultrasonic detector.

[0112] Step 101: Determine model information from a preset model database according to image detection information.

[0113] The model database stores model information corresponding to different shock absorber photos, which is pre-set by the staff and will not be described here. Model information refers to the thickness, appearance, shape and other parameter information of the shock absorber. The model information includes thickness reference range, arc state range, impact reference information, impact detection value, rotation completion position and reference coloring value. The image detection information is input into the model database to obtain the model information.

[0114] Step 102: Determine a thickness reference range according to the model information.

[0115] The thickness reference range refers to the standard thickness range of the shock absorber. The thickness reference range is included in the model information, so the thickness reference range can be determined by the model information.

[0116] Step 103: Obtain a thickness detection value from a preset thickness neural network model according to the ultrasonic detection information.

[0117] The thickness detection value refers to the thickness value obtained by detecting the shock absorber. The thickness neural network model is obtained by pre-inputting different ultrasonic detection information and training. The ultrasonic detection information is input into the preset thickness neural network model for analysis to obtain the thickness detection value.

[0118] Step 104: Determine whether the thickness detection value falls within the thickness reference interval.

[0119] By judging whether the thickness detection value falls within the thickness reference range, it is determined whether the thickness of the shock absorber is normal.

[0120] Step 1040: If the thickness detection value falls within the thickness reference range, the detection is completed, and the preset clamping device is controlled to clamp the shock absorber to the preset coloring area for coloring.

[0121] The clamping device is a preset manipulator used to grasp, fix and transfer the shock absorber, which is preset by the staff. The coloring area refers to the working area for coloring the shock absorber, which is preset by the staff.

[0122] If the thickness detection value falls within the thickness reference range, it means that there is no problem with the thickness, and the detection is completed, and the robot is controlled to clamp the shock absorber to the coloring area for coloring.

[0123] Step 1041: If the thickness detection value does not fall within the thickness reference interval, the thickness abnormality position is marked based on the ultrasonic detection information, and repaired using a preset thickness abnormality repair method.

[0124] The abnormal thickness position refers to the position of the shock absorber with abnormal thickness. If the thickness detection value does not fall into the thickness reference interval, it means that the thickness is abnormal. Then, the abnormal thickness position is marked in the ultrasonic detection information and repaired by a preset abnormal thickness repair method. The abnormal thickness repair method refers to a method for repairing a shock absorber with abnormal thickness. The abnormal thickness repair method includes steps 200 to 308.

[0125] Reference Figure 2 , abnormal thickness repair methods include:

[0126] Step 200: Determine an abnormal state based on ultrasonic detection information.

[0127] The abnormal state refers to the abnormal state of the shock absorber with abnormal thickness. The abnormal thickness may be caused by the thickness being too thin or by cracks, resulting in abnormal thickness. The ultrasonic detection information is input into the preset state neural network model for analysis to obtain the abnormal state. The state neural network model is obtained by the staff inputting different ultrasonic detection information in advance and training. The state neural network is pre-set by the staff and will not be elaborated here.

[0128] Step 201: Determine whether the abnormal state is consistent with a preset crack state.

[0129] The crack state refers to the state of abnormal cracks in the shock absorber. The repair method is determined by judging whether the abnormal state is consistent with the preset crack state.

[0130] Step 2010: If the abnormal state is consistent with the crack state, control the preset clamping device to clamp the shock absorber to the preset crack repair area, and repair it with the preset crack repair method.

[0131] The crack repair area refers to the range where the shock absorber can be repaired when cracks appear.

[0132] If the abnormal state is consistent with the crack state, it means that the abnormal thickness position of the shock absorber is a crack, then the robot is controlled to clamp the shock absorber to the crack repair area and repair it with a preset crack repair method. The crack repair method refers to a method for repairing the crack of the shock absorber. The crack repair method is steps 400 to 406.

[0133] Step 2011: If the abnormal state is inconsistent with the crack state, determine whether the thickness detection value is less than the minimum value of the thickness reference interval.

[0134] The minimum value of the thickness reference interval refers to the minimum value of the thickness of the shock absorber that can be used normally. If the abnormal state is inconsistent with the crack state, it means that the abnormal thickness position of the shock absorber is not a crack. Then, by judging whether the thickness detection value is less than the minimum value of the thickness reference interval, it is determined whether to cut or repair.

[0135] Step 202: If the thickness detection value is less than the minimum value of the thickness reference interval, determine the thickness difference value according to the thickness detection value and the minimum value of the thickness reference interval.

[0136] The thickness difference refers to the difference between the actual thickness of the shock absorber and the standard thickness. If the thickness test value is less than the minimum value of the thickness reference interval, it means that the thickness of the shock absorber at the abnormal thickness position is too thin. Then the difference between the thickness test value and the minimum value of the thickness reference interval is analyzed and calculated to obtain the thickness difference.

[0137] Step 203: Determine whether the thickness difference is within a preset reference repair interval.

[0138] The reference repair interval refers to the thickness interval that can be repaired, which is pre-set by the staff. Whether the repair can be performed is determined by judging whether the thickness difference is within the preset reference repair interval.

[0139] Step 2030: If the thickness difference is within the reference repair interval, a repair value is determined based on the thickness difference.

[0140] The repair value refers to the amount of repair when the shock absorber is too thin. If the thickness difference is within the benchmark repair range, it means that repair can be performed, and the thickness difference is input into the preset repair database to obtain the repair value. The repair database stores repair values ​​corresponding to different thickness differences. The repair database is pre-set by the staff and will not be described here.

[0141] Step 204: Determine a cooling value according to the repair value.

[0142] The cooling value refers to the parameter for cooling the repaired shock absorber. The repair value is input into a preset cooling database to obtain the cooling value. The cooling database stores cooling values ​​corresponding to different repair values. The cooling database is pre-set by the staff and will not be described in detail here.

[0143] Step 205: Control the preset manufacturing device to manufacture a patch block with the repair value, then control the preset repair device to weld the patch block, and control the preset cooling device to cool it with the cooling value. After the repair is completed, control the clamping device to clamp the shock absorber to the preset quality inspection area to inspect it with the preset repair quality inspection method.

[0144] The patch block is used to repair the thin part of the shock absorber. The manufacturing device is a preset 3D printing device, which is used to manufacture the patch block missing from the shock absorber. The repair device is a preset welder and manipulator, the manipulator is used to clamp the patch block, and the welder is used to weld the patch block. The cooling device is a preset movable blowing duct, which is composed of a manipulator and a blowing duct. The manipulator controls the blowing duct to move and blow air. The quality inspection area refers to the area where the repaired automobile shock absorber is quality inspected, which is pre-set by the staff. The repair quality inspection method refers to a method for quality inspection of the repaired automobile shock absorber. The repair quality inspection method is steps 500 to 5031.

[0145] Control the 3D printing equipment to manufacture a patch block with a patch value, then control the patch device to clamp the patch block to the abnormal thickness position and weld it, after welding, control the cooling device to cool the abnormal thickness position with a cooling value, after completing the patch, control the clamping device to clamp the shock absorber to a preset quality inspection area for inspection using a preset repair quality inspection method.

[0146] Step 2031: If the thickness difference is not within the reference repair interval, a preset clamping device is controlled to clamp the shock absorber to a preset waste area.

[0147] The waste area is an area for placing discarded shock absorbers, which is pre-set by the staff. If the thickness difference is not within the reference repair interval, it means that it cannot be repaired, and the robot is controlled to clamp the shock absorber to the preset waste area.

[0148] Reference Figure 3 , the abnormal thickness repair method also includes:

[0149] Step 300: If the thickness detection value is not less than the minimum value of the thickness reference interval, then determine the excess height value according to the thickness detection value and the maximum value of the thickness reference interval.

[0150] The excess height value refers to the value of the shock absorber thickness exceeding the standard thickness. If the thickness test value is not less than the minimum value of the thickness reference interval, it means that the thickness of the shock absorber at the abnormal thickness position exceeds the standard thickness. Then, the excess height value is determined by further analyzing and calculating the thickness test value and the maximum value of the thickness reference interval.

[0151] Step 301: Determine the excess volume according to the ultrasonic detection information and the excess height value, and define the abnormal thickness position as the abnormal height position.

[0152] The abnormal height position refers to the position where the shock absorber thickness is too high. The excess volume refers to the excess volume when the shock absorber thickness is too high. The area covered by the abnormal position in the ultrasonic detection information is analyzed and used as the excess area. The excess volume is determined by analyzing and calculating the excess area and the excess height value, and the thickness abnormal position is defined as the abnormal height position.

[0153] Step 302: Determine the arc state interval according to the model information.

[0154] The arc state interval refers to the position range interval of the arc state corresponding to the shock absorber. There are arc state positions and straight state positions on the shock absorber. The model information includes the arc state interval, so the arc state interval is determined by the model information.

[0155] Step 303: Analyze the ultrasonic detection information and the abnormal height position to determine whether the abnormal height position falls into the arc state interval.

[0156] By analyzing the ultrasonic detection information and the abnormal height position, it is determined whether the abnormal height position falls into the arc state interval, so as to determine the cutting method. The cutting methods include straight line cutting and arc cutting. When the abnormal height position does not fall into the arc state interval, it means that straight line cutting is performed. When the abnormal height position falls into the arc state interval, it means that straight line cutting is performed.

[0157] Step 3030: If the abnormal height position does not fall within the arc state interval, the straight line cutting position is determined according to the abnormal height position and the excess volume.

[0158] The straight-line cutting position refers to the position where the abnormal height position does not fall into the arc state interval and the shock absorber is cut in a straight line. If the abnormal height position does not fall into the arc state interval, it means that it can be cut in a straight line. Then, the abnormal height position and the excess volume are input into the preset linear neural network model for analysis to determine the straight-line cutting position. The linear neural network model is obtained by the staff inputting different abnormal height positions and excess volumes in advance and training.

[0159] Step 304: Determine the straight line cutting path according to the straight line cutting position.

[0160] The straight cutting path refers to the route corresponding to the straight cutting of the shock absorber. The route is formed by connecting adjacent positions through the straight cutting positions, and this route is the straight cutting path.

[0161] Step 305: Control the preset cutting device to cut the abnormal height position with a straight cutting path, and update the thickness detection value according to the ultrasonic detection information until the updated thickness detection value falls into the thickness reference range, and control the preset clamping device to clamp the shock absorber to the preset coloring area for coloring.

[0162] The cutting device is a preset cutting machine used to cut the shock absorber. The cutting machine is controlled to cut the abnormal height position in a straight cutting path, and the thickness detection value is updated through ultrasonic detection information until the updated thickness detection value falls into the thickness reference range, and then the manipulator is controlled to clamp the shock absorber to the preset coloring area for coloring.

[0163] Step 3031: If the abnormal height position falls into the arc state interval, the arc cutting position is determined according to the abnormal height position and the excess volume.

[0164] The arc cutting position refers to the position where the shock absorber is cut when the abnormal height position falls into the arc state interval. If the abnormal height position falls into the arc state interval, it means that a straight line cannot be cut during cutting. The abnormal height position and the excess volume are input into the preset arc neural network model for analysis to determine the arc cutting position. The arc neural network model is obtained by pre-inputting different abnormal height positions and excess volumes and training.

[0165] Step 306: Determine height information according to the model information and a preset thickness database.

[0166] The height information refers to the height information corresponding to the arc bending position of the shock absorber. The thickness database stores the height information corresponding to different model information. The thickness database is pre-set by the staff and will not be described here. The height information is obtained by inputting the model information into the thickness database.

[0167] Step 307: Determine the arc cutting path according to the height information and the arc cutting position.

[0168] The arc cutting path refers to the arc route for cutting the shock absorber. The height value corresponding to the arc cutting position is retrieved through the height information and compared with the reference height in the height information, and the path is determined based on the comparison result. If there is a height difference between adjacent positions on this path, the cutting route is adjusted according to the height of the adjacent positions on the path, and the cutting is performed in accordance with the height. The arc cutting position of this path is used to connect the adjacent positions to form an arc route, which is the arc cutting path.

[0169] Step 308: Control the preset cutting device to cut the abnormal height position with an arc cutting path, and update the thickness detection value according to the ultrasonic detection information until the updated thickness detection value falls into the thickness reference range, and control the preset clamping device to clamp the shock absorber to the preset coloring area for coloring.

[0170] The cutting machine is controlled to cut the abnormal height position with an arc cutting path, and the thickness detection value is updated through ultrasonic detection information until the updated thickness detection value falls into the thickness reference range, and the robot is controlled to clamp the shock absorber to the preset coloring area for coloring.

[0171] Reference Figure 4 , crack repair methods include:

[0172] Step 400: Acquire crack detection information in the crack repair area.

[0173] The crack repair area refers to the area where the cracks of the shock absorber are repaired, which is preset by the staff. The crack detection information refers to the information obtained by ultrasonic detection of the cracks of the shock absorber, which is obtained by a preset ultrasonic detector.

[0174] Step 401: Determine the crack value according to the crack detection information and the thickness abnormality position.

[0175] The crack value is an ultrasonic abnormality value used to indicate the abnormality of the crack area and depth. The crack value is determined by analyzing the thickness abnormality position in the crack detection information.

[0176] Step 402: Determine the crack depth and crack area according to the crack value.

[0177] The crack depth refers to the vertical distance from the shock absorber surface to the deepest part of the crack along the crack extension direction. The crack area refers to the area of ​​the shock absorber crack. The crack value is input into the preset crack database to obtain the crack depth and crack area. The crack database stores the crack depth and crack area corresponding to different crack values. The crack database is pre-set by the staff and will not be described here.

[0178] Step 403: Determine repair parameters according to the crack depth and crack area.

[0179] The repair parameter refers to the volume value of the repair fluid used to repair the cracks in the shock absorber. The crack depth and crack area are input into a preset parameter database to obtain the repair parameter. The parameter database stores repair parameters corresponding to different crack depths and crack areas. The parameter database is pre-set by the staff and will not be described in detail here.

[0180] Step 404: Determine the cooling temperature according to the repair parameters.

[0181] The cooling temperature refers to the temperature at which the crack is cooled after being repaired. The repair parameters are input into the preset temperature database to obtain the cooling temperature. The temperature database stores the cooling temperatures corresponding to different repair parameters. The temperature database is pre-set by the staff and will not be described in detail here.

[0182] Step 405: Determine the grinding value according to the crack area.

[0183] The grinding value refers to the value of the surface grinding after the crack of the shock absorber is repaired. The crack area is input into the preset grinding database to obtain the grinding value. The grinding database stores the grinding values ​​corresponding to different crack areas. The grinding database is pre-set by the staff and will not be described here.

[0184] Step 406: Control the preset crack repair device to repair the abnormal thickness position with the repair parameters, control the preset cooling device to cool with the cooling temperature, control the preset grinding device to grind with the grinding value, and then control the clamping device to clamp the shock absorber to the preset quality inspection area to inspect with the preset repair quality inspection method.

[0185] The crack repair device is a preset welder, which is used to repair and weld the cracks of the shock absorber. The cooling device is a preset fan, which is used to cool the shock absorber. The grinding device is an angle grinder, which is used to grind the crack position after repair. The repair quality detection method refers to a method for quality detection of the repaired shock absorber. The repair quality detection method is steps 500 to 5031.

[0186] Repair quality testing methods include:

[0187] Step 500: Determine shock reference information and shock detection value according to model information.

[0188] The impact reference information refers to the image information corresponding to the standard form after the shock absorber is quality tested. The impact test value refers to the parameter value of the shock absorber. The model information includes the impact reference information and the impact test value, so that the impact reference information and the impact test value are determined by the model information.

[0189] Step 501: Control a preset impact device to detect the abnormal thickness position with an impact detection value, and simultaneously obtain quality detection image information in the quality detection area.

[0190] The impact device is a preset pressure testing machine used to test the bearing capacity of the shock absorber after repair. The quality inspection image information refers to the photos of the shock absorber after quality inspection, which are obtained through the camera preset in the quality inspection area. The impact device is controlled to detect the abnormal thickness position with the impact detection value, and the quality inspection image information in the quality inspection area is obtained through the camera.

[0191] Step 502: Determine whether the quality inspection image information is consistent with the impact reference information.

[0192] By judging whether the quality inspection image information is consistent with the impact reference information, it can be determined whether the quality of the repaired shock absorber is up to standard.

[0193] Step 5020: If the quality inspection image information is inconsistent with the impact reference information, clamp it to the waste area.

[0194] If the quality inspection image information is inconsistent with the impact reference information, it means that the repaired shock absorber has quality problems and deformation, and the shock absorber is clamped to the scrap area.

[0195] Step 5021: If the quality inspection image information is consistent with the impact reference information, determine whether the quality inspection image information contains a preset crack feature.

[0196] The crack feature refers to the shape feature of the crack on the shock absorber, which is preset by the staff. If the quality inspection image information is consistent with the impact reference information, it means that the repaired shock absorber is of good quality and has not been deformed. Then, by judging whether the quality inspection image information contains the preset crack feature, it is determined whether the repair needs to be continued.

[0197] Step 50210: If the quality inspection image information contains preset crack features, determine the crack position and crack value based on the quality inspection image information.

[0198] The crack value refers to the degree of cracks on the shock absorber, including the size and depth of the cracks. The crack location refers to the location of the cracks on the shock absorber after the shock absorber is quality tested.

[0199] If the quality inspection image information contains a preset crack feature, it means that the shock absorber has cracks after the quality inspection. Then, a coordinate system is established in the quality inspection image information, and the crack position is determined by the position covered by the obstruction feature in the coordinate system. The quality inspection image information is input into the preset crack neural network model for analysis to determine the crack value. The crack neural network model is obtained by pre-inputting different quality inspection image information by the staff and training.

[0200] Step 503: Determine whether the crack value is within a preset crack repairing range.

[0201] The crack repair interval refers to the interval in which cracks can be repaired after the shock absorber is inspected for quality. The crack repair interval is preset by the staff and will not be described in detail here. Whether the crack value is within the preset crack repair interval is determined to determine whether it can be repaired.

[0202] Step 5030: If the crack value is within the crack repair interval, a repair value is determined according to the crack value, and a preset crack repair device is controlled to repair the crack position with the repair value.

[0203] If the crack value is within the crack repair interval, it means that the crack is very small and can be repaired, and the crack repair device is controlled to repair the crack position of the shock absorber with the repair value.

[0204] Step 5031: If the crack value is not within the crack repairing range, control a preset clamping device to clamp the shock absorber to a preset waste area.

[0205] If the crack value is not within the crack repair range, indicating that the crack cannot be repaired, the robot arm is controlled to clamp the shock absorber to a preset waste area.

[0206] Step 50211: If the image detection information does not contain the preset crack features, control the preset clamping device to clamp the shock absorber to the preset coloring area for coloring.

[0207] If the image detection information does not contain the preset crack features, it means that the quality of the shock absorber after the quality inspection meets the standards, and the robot arm is controlled to clamp the shock absorber to the preset coloring area for coloring.

[0208] Controlling a preset clamping device to clamp the shock absorber to a preset coloring area for coloring includes:

[0209] Step 600: Obtain coloring detection information in the coloring area.

[0210] The coloring detection information refers to a photo of the shock absorber when it is colored, which is obtained through a camera preset in the coloring area.

[0211] Step 601: Determine whether the coloring detection information contains preset foreign matter features.

[0212] The foreign matter feature refers to the feature of dust or stains on the shock absorber. By judging whether the coloring detection information contains the preset foreign matter feature, it is determined whether the foreign matter needs to be processed before coloring the shock absorber.

[0213] Step 602: If the coloring detection information contains foreign matter features, determine the foreign matter value and the foreign matter position according to the coloring detection information.

[0214] The foreign matter value refers to the parameter value of dust or stains on the shock absorber. The foreign matter position refers to the position of dust or stains on the shock absorber. If the coloring detection information contains foreign matter features, it means that there is foreign matter on the shock absorber. Then, a coordinate system is established in the coloring detection information, and the position of the foreign matter is determined by the position covered by the foreign matter features in the coordinate system. The coloring detection information is analyzed to determine the size and type of the foreign matter, and the foreign matter value is determined by the size and type of the foreign matter.

[0215] Step 603: Determine whether the foreign matter value is within a preset blowing range.

[0216] The blowing range refers to the range in which the foreign matter corresponding to the foreign matter value can be blown away. The blowing range is preset by the staff. By judging whether the foreign matter value is within the preset blowing range, the treatment method for the foreign matter is determined.

[0217] Step 6030: If the foreign matter value is within the blowing range, the blowing force is determined according to the foreign matter value, and the preset blowing device is controlled to blow air at the foreign matter position with the blowing force until the coloring detection information does not contain foreign matter features.

[0218] Blowing force refers to the force used to control the blowing device to blow air. The blowing device is a movable nozzle for blowing air at foreign objects. The blowing force corresponding to different foreign object values ​​is stored in the blowing database. The blowing database is pre-set by the staff and will not be described here. If the foreign object value is in the blowing range, it means that the foreign object can be blown. The foreign object value is input into the preset blowing database to obtain the blowing force, and the blowing device is controlled to blow air at the foreign object position with the blowing force, and the coloring detection information is updated until the coloring detection information does not contain foreign object features, and the blowing is completed.

[0219] Step 6031: If the foreign matter value is not within the blowing range, the foreign matter area is determined based on the coloring detection information.

[0220] The foreign body area refers to the area occupied by dust or stains on the shock absorber. If the foreign body value is not in the blowing range, it means that the foreign body cannot be blown away. The foreign body area is determined by the area covered by the foreign body value in the coordinate system of the color detection information.

[0221] Step 604: Determine the cleaning amount according to the foreign matter value.

[0222] The cleaning volume refers to the volume value of the cleaning fluid used to clean the shock absorber. The foreign matter value is input into the preset cleaning database to obtain the cleaning volume. The cleaning database stores the cleaning volumes corresponding to different foreign matter values. The cleaning database is pre-set by the staff and will not be described here.

[0223] Step 605: Determine the cleaning force and cleaning time according to the area of ​​the foreign matter and the cleaning amount, control the preset cleaning device to spray the foreign matter position with the cleaning amount, and brush the foreign matter position with the cleaning force and cleaning time until the color detection information does not contain foreign matter features.

[0224] The cleaning force refers to the force of cleaning the shock absorber. The cleaning time refers to the time of cleaning the shock absorber. The cleaning device is a spray cleaning machine, which includes a rotating brush and a nozzle. The rotating brush is used for brushing, and the nozzle is used for spraying the cleaning liquid. The spray cleaning machine is controlled to spray the foreign body position with the cleaning amount, and brush the foreign body position with the cleaning force and cleaning time, and the coloring detection information is updated until the coloring detection information does not contain the foreign body characteristics, and the brushing is completed.

[0225] When controlling the preset clamping device to clamp the shock absorber to the preset coloring area for coloring, it also includes:

[0226] Step 700: If the coloring detection information does not contain foreign matter features, control the preset spraying device to spray the shock absorber, and determine the coloring completion position and the reference coloring value according to the model information.

[0227] The spraying device is a spraying machine preset in the coloring area, which is used to spray and color multiple shock absorbers. The coloring completion position refers to the position where the shock absorber is completed. The reference coloring value refers to the standard coloring degree after the shock absorber is colored. The coloring detection information does not contain foreign matter features, indicating that coloring can be performed, then the spraying device is controlled to spray the shock absorber, and the model information contains the rotation completion position and the reference coloring value, and the rotation completion position and the reference coloring value are determined by the model information.

[0228] Step 701: Determine the coloring completion value according to the coloring detection information and the rotation completion position.

[0229] The coloring completion value refers to the degree of coloring completion of the shock absorber. The rotation completion position is photographed and identified through the coloring detection information, and the coloring degree of this position is obtained through analysis, and the coloring completion value is determined by the coloring degree.

[0230] Step 702: Determine whether the reference coloring value is consistent with the coloring completion value.

[0231] By judging whether the reference coloring value is consistent with the coloring completion value, it is determined whether the coloring is complete.

[0232] Step 7020: If the reference coloring value is consistent with the coloring completion value, coloring is completed.

[0233] If the reference coloring value is consistent with the coloring completion value, it means that the coloring is complete and the coloring is completed.

[0234] Step 7021: If the reference coloring value is inconsistent with the coloring completion value, determine the abnormal coloring position based on the coloring detection information.

[0235] The abnormal coloring position refers to the position where the shock absorber is not successfully colored after coloring. If the reference coloring value is inconsistent with the coloring completion value, it means that some part has not been successfully colored. Then, the abnormal coloring position is determined by analyzing the coloring situation in the coloring detection information.

[0236] Step 703: Determine whether the abnormal coloring position is within the preset regional spraying interval.

[0237] The regional spraying interval refers to the location area where the shock absorber can be recolored in the coloring area. The regional spraying interval is pre-set and stored by the staff. The coloring method is determined by judging whether the abnormal coloring position is within the preset regional spraying interval.

[0238] Step 7030: If the abnormal coloring position is not within the preset regional spraying interval, the preset coloring method is used for coloring.

[0239] If the coloring abnormal position is not within the preset area spraying interval, it means that the coloring area cannot be successfully supplemented with color, and the coloring is supplemented with the preset coloring method. The coloring method refers to the coloring method when the coloring area cannot be supplemented with color. The coloring method is steps 800 to 806.

[0240] Step 7031: If the abnormal coloring position is within the preset regional spraying interval, the abnormal coloring area is determined based on the abnormal coloring position and the coloring detection information.

[0241] The coloring abnormal area refers to the area of ​​the shock absorber to be supplemented with color. If the coloring abnormal position is within the preset regional spraying interval, the coloring abnormal area is determined by the area covered by the coloring abnormal position in the coordinate system of the coloring detection information.

[0242] Step 704: Determine the separate spraying direction and separate spraying amount according to the abnormal coloring position and the abnormal coloring area.

[0243] The individual spraying direction refers to the angle and orientation of the shock absorber for color correction, so that the paint can be accurately sprayed in the direction of the specific position that needs to be repaired or supplemented with color. The individual spraying amount refers to the amount of spraying for the shock absorber for color correction. By analyzing the abnormal coloring position, the individual spraying direction is determined, and the abnormal coloring area and the abnormal coloring area are input into the preset individual spraying database to obtain the individual spraying amount. The individual spraying database stores the individual spraying amounts corresponding to different abnormal coloring positions and abnormal coloring areas. The individual spraying database is pre-set by the staff and will not be repeated here.

[0244] Step 705: Control the preset separate spraying device to spray the abnormal coloring position with a separate spraying direction and a separate spraying amount, and reacquire the coloring detection information until the reference coloring value is consistent with the coloring completion value, and then the detection is completed.

[0245] The separate spraying device includes a spray gun and a manipulator, and the manipulator moves the spray gun to perform color correction. The separate spraying device is controlled to spray the abnormal coloring position of the shock absorber in a separate spraying direction and a separate spraying amount, and the coloring detection information is re-acquired until the reference coloring value is consistent with the coloring completion value, indicating that the color correction is completed, and the detection is completed.

[0246] Coloring methods include:

[0247] Step 800: Control a preset clamping device to clamp the shock absorber corresponding to the abnormal coloring position to a preset color-complementing area.

[0248] The color-complementing area refers to an area for color-complementing the incompletely colored shock absorber. The manipulator is controlled to clamp the shock absorber corresponding to the abnormally colored position to the preset color-complementing area.

[0249] Step 801: Obtain scanning information in the complementary color area.

[0250] The scanning information refers to the coloring information of the shock absorber, which is obtained through a preset coating thickness gauge. The scanning information in the complementary color area is obtained through the coating thickness gauge.

[0251] Step 802: Determine the color-complementing area according to the abnormal coloring position and the scanning information.

[0252] The color-complementing area refers to the area on the shock absorber that needs to be color-complemented. The color-complementing area is determined by analyzing the position corresponding to the abnormal coloring position in the scanning information.

[0253] Step 803: Determine the complementary color amount according to the complementary color area.

[0254] The complementary color amount refers to the amount of complementary color for the shock absorber. The complementary color area is input into a preset complementary color database to obtain the complementary color amount. The complementary color database stores complementary color amounts corresponding to different complementary color areas. The complementary color database is preset by the staff and will not be described in detail here.

[0255] Step 804: Determine the color complement direction according to the abnormal coloring position and the scanning information.

[0256] The color complement direction refers to the color complement direction of the color complement device when performing color complement. The color complement device is a spray gun and a robot preset in the color complement area, and the robot controls the spray gun to move. The coloring situation of the abnormal coloring position is retrieved through scanning information, and the coloring situation is analyzed to determine the color complement direction.

[0257] Step 805: Determine the coloring path according to the complementary color direction, complementary color area and scanning information.

[0258] The coloring path refers to the moving path when the shock absorber is color-complemented in the color-complementing area. The concave-convexity of the position where the coloring needs to be complemented is determined by scanning information and the color-complementing area. If the coloring path is concave-convex, it means that it may be necessary to turn for coloring. If the coloring path is not concave-convex, it means that it can be colored in a straight line. The coloring path is determined by analyzing the concave-convexity of the position where the coloring needs to be complemented and the complementary color direction.

[0259] Step 806: Control the preset color-correcting device to perform color correction on the abnormally colored position using the color path and the color correction amount.

[0260] The color-complementing device is controlled to move along the coloring path, and color-complements the abnormal coloring position with the color-complementing amount.
