[0037] like Figures 1 to 8 As shown, the present invention provides a motor housing surface cleaning system, comprising:

[0038] S1. Acquire cleaning requirement information through industrial camera 3, the cleaning requirement information including: location information of pollutants on the motor housing, information on the area covered by pollutants, and information on the type of pollutants;

[0039] S2. Generate a cleaning plan based on the cleaning requirement information using a preset plan matching model. The cleaning plan includes at least one of cleaning agent supply amount information, a cleaning nozzle posture parameter range, equipment control parameters, and cleaning process information. The plan matching model is a machine learning model trained using historical data.

[0040] S3, obtaining the posture of the cleaning nozzle in the cleaning chamber 1, the posture of the cleaning nozzle including: the height of the cleaning nozzle, the rotation angle of the cleaning nozzle, and the spray pressure;

[0041] S4. Configure and call the cleaning agent according to the cleaning plan, select and determine the appropriate cleaning nozzle, clean the motor housing with the most appropriate spray pressure, and send the equipment control parameters to the solenoid valve of the corresponding cleaning nozzle for parameter setting;

[0042] Generate a normal control instruction based on the cleaning process information, and send the normal control instruction to the corresponding cleaning nozzle, so that the cleaning nozzle cleans the contaminants on the motor housing according to the cleaning process information and the cleaning nozzle posture;

[0043] S4.1. Selecting a cleaning nozzle based on the cleaning plan specifically includes the following steps: Based on the location and coverage area of ​​the pollutants in the cleaning plan, matching the cleaning nozzle posture parameters, and selecting a cleaning nozzle that meets the following conditions: the cleaning nozzle height covers the vertical distribution range of the pollutants; the cleaning nozzle rotation angle matches the horizontal position of the pollutants; and the spray pressure is adapted to the pollutant type and coverage area;

[0044] S4.2. If there are cleaning nozzles that meet the requirements, the cleaning cost coefficient of each cleaning nozzle is calculated using a pre-set cost calculation formula. The cleaning nozzle with the lowest cost is selected and cleaned at the most appropriate spray pressure. The cost coefficient calculation formula is as follows:

[0045]

[0046] Wherein, Y is the cleaning cost coefficient of the cleaning nozzle (unit: yuan), Q is the cleaning agent cost (unit: yuan), wi is the spray power of the i-th operating period (unit: J / s), Ti is the spray duration of the i-th operating period (unit: s), C is the unit price of energy consumption (unit: yuan / J), Si is the ratio of the effective coverage area of ​​the cleaning nozzle to the pollutant area, Si is dimensionless and Si is greater than 0; wherein, the cleaning cost includes the total cost of tap water consumed by the cleaning nozzle during the cleaning process, and the cleaning agent cost includes the total cost of chemical cleaning agents consumed during the cleaning process;

[0047] S4.3. If there is no cleaning nozzle that meets the requirements, the suboptimal solution is calculated using the dynamic scoring formula:

[0048] Z=Y+α·ΔH+β·Δθ

[0049] Among them, Z is the comprehensive score, ΔH is the deviation between the cleaning nozzle height and the target height (unit: mm), Δθ is the deviation between the cleaning nozzle angle and the target angle (unit: degree), and ΔH and Δθ are not 0, α (unit: yuan / height) and β (unit: yuan / angle) are the weight coefficients of experimental calibration.

[0050] S5. Capture a video of the pollutant cleaning process based on the cleaning process information, analyze the captured image information using a video-assisted model pre-set in the system, and generate a cleaning nozzle parameter adjustment instruction to adjust the cleaning nozzle;

[0051] Among them, the video-assisted model is a lightweight convolutional neural network model, which is trained through the following data: template image data of the motor housing surface, multi-angle image samples before and after cleaning of motor housing pollutants, cleaning effect annotation data under different cleaning nozzle postures (height, rotation angle, injection pressure), and correlation data between cleaning agent type and pollutant removal efficiency.

[0052] In step S5, based on the cleaning process information, a video of the pollutant cleaning process is captured, and the specific steps of generating a cleaning nozzle parameter adjustment instruction through video-assisted model analysis include:

[0053] Real-time acquisition of image information on the motor housing surface based on cleaning process information;

[0054] Image information is preprocessed to enhance the contrast of the polluted area. Image preprocessing includes: Gaussian filtering to reduce noise on the collected image; perspective correction of the denoised image to eliminate image distortion caused by the motor housing curve; adaptive histogram equalization to enhance the contrast between the polluted area and the background; and regional segmentation of the image to extract pixel coordinates and contour information of the pollutant coverage area.

[0055] The pre-processed image is input into the video-assisted model, which generates adjustment instructions for the cleaning nozzle height, rotation angle and injection pressure by identifying the coverage area and location of residual pollutants.

[0056] Preferably, it also includes a preprocessing step for the motor housing to be cleaned: collecting the initial image of the motor housing based on the cleaning requirement information; reconstructing the three-dimensional point cloud of the initial image to extract the vertical projection area and spatial position of the pollutant area; generating the initial posture parameters (height, angle) of the cleaning nozzle according to the projection area and position, and using them as input conditions for the cleaning plan.

[0057] Preferably, after cleaning is completed, the surface of the motor housing is subjected to a secondary inspection through the final inspection module. If there are residual stains, a local rewash instruction is triggered; the generation of the local rewash instruction of the final inspection module includes the following steps: collecting a high-resolution image of the motor housing after cleaning through an offline visual inspection station; coordinate locating the residual stain area; calling a low-pressure fine cleaning nozzle to perform fixed-point rewashing on the located area.

[0058] Preferably, after cleaning is completed, the actual cleaning nozzle posture parameters (height, angle, pressure) and the corresponding cleaning effect data are collected; the data collected by the offline visual inspection station are compared with the predicted results, and the cleaning coverage deviation and energy consumption deviation are calculated; the training set of the scheme matching model is updated according to the deviation data, and the cleaning nozzle posture parameter matching logic is optimized.

[0059] When cleaning the motor housing, the secondary splash of high-pressure water may cause water film / water droplets to adhere to the shield of the industrial camera 3, causing the following problems: image blur (MTF decreases ≥40%), optical distortion (refractive index changes resulting in ±5% dimensional measurement error), and corrosion risk (residual droplets containing detergent); in order to ensure the accuracy of visual inspection and reduce the impact of water mist generated during the cleaning process on the industrial camera 3, a protective plate 2013 is set under the shooting end of the industrial camera 3 to prevent water mist from directly affecting the lens; and a replacement mechanism 2 for replacing the protective plate 2013 is provided to replace the protective plate 2013.

The shooting end of the industrial camera 3 is aligned so as not to hinder the normal shooting of the industrial camera 3; or the main body of the replacement disk 2012 is opposite to the shooting end of the industrial camera 3, so as to close the industrial camera 3 when it is stopped; when the protective sheet 2013 in front of the industrial camera 3 is covered with water mist or stains, the motor 2014 drives the rotation to quickly switch to a new protective sheet 2013, and the contaminated protective sheet 2013 can also be cleaned by the cleaning mechanism to achieve fast replacement and recycling; the clarity is monitored in real time through the modulation transfer function of the industrial camera 3, and replacement is automatically triggered when it drops by more than 15%.

At the same time, the introduced high-pressure gas can increase the pressure inside the premixing box 204, making it easier for the liquid in the premixing box 204 to be sprayed from the nozzle 206 onto the protective sheet 2013, thereby continuously cleaning the protective sheet 2013.
