Description

TECHNICAL FIELD

[0001] The present application relates to the field of die casting process, in particular to a die casting demolding method and device for an engine shock absorber aluminum bracket. BACKGROUND

[0002] At present, with the development of manufacturing industry, die casting technology is widely used in aluminum alloy and other light metal materials due to its fast production speed and suitability for mass production, which helps to realize the lightweight of products.

[0003] In the current die casting production process, the castings after die casting include castings and waste, and the castings and waste are separated by demolding agent. The spraying of the demolding agent is operated by manual experience or fixed preset program. Manual spraying depends on experience to determine the spraying position and spraying amount of the demolding agent, and the fixed preset program determines the spraying position and spraying amount of the demolding agent according to the set instructions.

[0004] For the related technology in the above, in die casting production, each demolded casting may be different due to slight differences in metal liquid temperature, mold temperature, demolding force and other parameters, and manual experience and fixed preset program often fail to judge when facing different casting models. SUMMARY

[0005] In order to realize the accurate spraying of the demolding agent for different casting models, the present application provides a die casting demolding method and device for an engine shock absorber aluminum bracket.

[0006] In the first aspect, the present application provides a die casting demolding method for an engine shock absorber aluminum bracket, which adopts the following technical scheme: A die casting demolding method for an engine shock absorber aluminum bracket, comprising: S1: acquiring a casting surface image and a casting model; S2: determining a corresponding spraying position according to the casting model; S3: judging a die casting degree based on the casting surface image and the spraying position; S4: querying a spraying amount corresponding to the die casting degree according to a preset casting model library, and performing a spraying operation according to the spraying position and the spraying amount, and generating a spraying completion signal after completing the spraying operation; S5: collecting a spraying surface image in response to the spraying completion signal; S6: extracting a key spraying area corresponding to the casting model from the casting model library; S7: identifying an over-spraying area based on the spraying surface image; S80: if the key spraying area has an over-spraying area, determining a demolding agent residual amount according to the over-spraying area; S81: If the release agent residual amount exceeds the preset standard release agent residual amount, control the blowing assembly (3) to perform blowing operation on the oversprayed area with preset normal blowing parameters; S9: According to the sprayed surface image and the key spraying area, identify whether there is an undersprayed area; if there is the undersprayed area, repeat the spraying operation.

[0007] By adopting the above technical solutions, accurate spraying of release agent for different casting models is realized, after spraying is completed, the spraying quality can be automatically detected, and corresponding adjustment is made according to the detection result. If there is an undersprayed area, the system will re-execute the spraying operation to ensure that the casting surface is uniformly and completely sprayed. At the same time, for the oversprayed area, the system will detect the residual amount of release agent, and when the residual amount exceeds the standard, blowing operation will be performed by the blowing assembly with preset normal blowing parameters to remove excess release agent. This automatic detection and adjustment mechanism not only improves the accuracy and efficiency of spraying, but also effectively avoids errors and waste that may be caused by manual operation.

[0008] Optionally, if the undersprayed area exists, the method of repeatedly performing the spraying operation comprises: S90: When the oversprayed area exists, determine the first casting clamping state based on the oversprayed area and the undersprayed area; S91: Control the casting to make clamping adjustment according to the first casting clamping state, so that the release agent in the oversprayed area flows along the casting to the undersprayed area; S92: When the oversprayed area does not exist, determine the current release agent residual amount based on the sprayed surface image; S93: When the current release agent residual amount exceeds the preset minimum adjustment amount, determine the release agent residual area; S94: Determine the second casting clamping state according to the release agent residual area and the undersprayed area; S95: Control the casting to make clamping adjustment according to the second casting clamping state, so that the release agent in the release agent residual area flows along the casting to the undersprayed area; S96: When there is no oversprayed area and release agent residual area, repeat the spraying operation.

[0009] By adopting the technical scheme, fine adjustment strategies are further provided for processing of the insufficient spraying area and the excessive spraying area. When the system detects the insufficient spraying area, instead of simply repeating the spraying operation, the relative positional relationship between the excessive spraying area and the insufficient spraying area is determined through intelligent analysis, and then the clamping state of the casting is adjusted, and the excessive release agent in the excessive spraying area is ingeniously used to supplement the insufficient spraying area. This strategy not only improves the utilization rate of the release agent, but also effectively avoids the material waste and efficiency reduction caused by repeated spraying.

[0010] Optionally, the method further comprises updating the casting model library, and the method comprises: The method further comprises updating the casting model library, and the method comprises: S960: accumulating the number of continuous excessive spraying times when the excessive spraying area exists; S961: accumulating the number of continuous insufficient spraying times when the insufficient spraying area exists; S962: determining the casting feature based on the casting surface image when the number of continuous excessive spraying times falls within a preset abnormal excessive spraying time threshold value or when the number of continuous insufficient spraying times falls within a preset abnormal insufficient spraying time threshold value; S963: searching the casting model library based on the casting feature to obtain a similar casting model; S964: performing S3 to S9 according to the spraying position corresponding to the similar casting model to obtain a similar insufficient spraying area and a similar excessive spraying area; S965: performing the spraying operation based on the similar casting model when the similar insufficient spraying area and the similar excessive spraying area do not exist.

[0011] By adopting the technical scheme, when the system detects the continuous excessive spraying or insufficient spraying, it is determined whether an error is generated in the process of identifying the casting model. It is possible that a casting model with similar casting features exists, and the system erroneously judges it as the current casting model due to the similar casting model, thereby causing inaccurate spraying amount. In order to correct the error, the system accumulates the number of continuous excessive spraying or insufficient spraying, and when the number reaches a preset abnormal value, the casting feature is determined again based on the casting surface image, the similar casting model is searched through the casting model library, and the release operation is performed based on the similar casting model. If the similar casting model does not have the excessive spraying and insufficient spraying, it is indicated that the similar casting model is the model of the current casting.

[0012] Optionally, the method further comprises updating the casting model library if the similar insufficient spraying area and the similar excessive spraying area still exist, and the method comprises: S9650: determining surplus release agent residue when the continuous over-spraying times fall into the abnormal over-spraying times threshold value; S96501: determining average release agent residue according to the surplus release agent residue; S96502: adjusting the spraying operation corresponding to the casting model based on the average release agent residue and the release agent residue area, and defining as the corrected spraying operation; S9651: adjusting the spraying operation corresponding to the casting model based on the preset spraying amount increasing method when the continuous under-spraying times fall into the abnormal under-spraying times threshold value, and defining as the corrected spraying operation; S96511: updating the casting model library based on the corrected spraying operation and the casting model.

[0013] By adopting the above technical solutions, when the system detects continuous over-spraying or under-spraying, and after performing the release operation based on the similar casting model, there are still similar over-spraying areas and similar under-spraying areas, the system can determine that it is not an identification error of the casting model, and adjust the spraying operation for the image of the current casting model and the over-spraying and under-spraying conditions to form a corrected spraying operation. Finally, the system will update the casting model library based on these corrected spraying operations and the casting model to improve the accuracy and efficiency of subsequent release operations.

[0014] Optionally, the method for controlling the casting to perform clamping adjustment comprises: S970: determining a guide direction and a guide distance based on the over-spraying area and the under-spraying area when the first casting clamping state exists; S971: determining the guide direction and the guide distance based on the release agent residue area and the over-spraying area when the second casting clamping state exists; S972: determining a guide angle based on the guide direction, the guide distance, the release agent residue, and a preset release agent flow speed; S9720: controlling the casting to perform clamping adjustment based on the guide angle; S9721: acquiring a real-time release agent flow video during the clamping adjustment process; S9722: analyzing the real-time release agent flow video to obtain a release agent guide speed and a release agent acceleration; S9723: adjusting the guide angle in real time based on the release agent acceleration, and defining the guide angle as a dynamic guide angle; S9724: acquiring a current release agent residue distance when the dynamic guide angle is a preset horizontal angle and the release agent does not enter the under-spraying area; S9725: forming a blowing parameter based on the release agent residual distance and the oversprayed area; S9726: controlling the blowing assembly (3) to perform the blowing operation based on the blowing parameter; S9727: determining the horizontal angle based on the oversprayed area in the absence of the guide angle, and controlling the casting clamping state to adjust the clamping angle according to the horizontal angle; S9728: reacquiring the casting surface image to determine the current guide direction and guide distance; S9729: forming a blowing parameter based on the current guide direction and the current guide distance, and performing S9726.

[0015] By adopting the above technical solution, in the process of controlling the clamping adjustment of the casting, the system determines the guide direction and guide distance according to the relative position relationship between the oversprayed area and the undersprayed area, or the release agent residual area and the oversprayed area. The system comprehensively considers the guide direction, guide distance, release agent residual amount, and preset release agent flow speed, and calculates the optimal guide angle through an intelligent algorithm. After the guide angle is determined, the system controls the casting to perform corresponding clamping adjustment, so as to ensure that the release agent can smoothly and accurately flow to the undersprayed area, thereby realizing efficient use of the release agent.

[0016] Optionally, the method further comprises re-determining the guide direction and the guide distance, and the method comprises: S9730: determining an adjustable area in the presence of the oversprayed area or the release agent residual area, and accumulating the number of adjustable areas; S9731: determining a corrected guide direction and a corrected guide distance based on the adjustable area in the presence of the number of adjustable areas being not 1; S9732: determining a corrected guide angle based on the corrected guide direction and the corrected guide distance; S9733: adjusting the clamping angle based on the corrected guide angle, and performing S9730 to S9733; S9734: performing S90 to S9729 in the presence of the number of adjustable areas being 1; S9735: controlling the blowing assembly (3) to perform the blowing operation on the adjustable area with the conventional blowing parameter in the absence of the corrected guide angle.

[0017] By adopting the above technical solutions, in the process of re-determining the guiding direction and the guiding distance, when the system detects that there are multiple adjustable areas, the number of these adjustable areas is accumulated, and the correction guiding angle is determined according to the positions and characteristics of these areas, and the clamping angle of the casting is adjusted based on the correction guiding angle, until the number of adjustable areas is reduced to one. When the number of adjustable areas is reduced to one, the system re-executes the adjustment of the spraying operation and the blowing operation according to the previous steps to ensure that the release agent can uniformly and accurately cover the surface of the casting. If the system cannot determine the correction guiding angle, that is, all possible adjustment directions have been tried, but the ideal spraying effect has not been achieved, at this time, the system controls the blowing assembly to perform the blowing operation on the adjustable area with the conventional blowing parameters to remove the excess release agent or supplement the area with insufficient spraying. This flexible and refined adjustment mechanism enables the present application to adapt to different casting models and complex and variable spraying requirements, improving the flexibility and efficiency of die casting production.

[0018] Optionally, the method further comprises a blowing operation when the release agent flow direction cannot be adjusted by the guiding angle, the method comprising: S97230: determining a predicted release agent flow direction according to the real-time release agent flow video; S97231: accumulating the number of times of continuous release agent flow direction path deviation when the predicted release agent flow direction is not the guiding direction; S97232: adjusting the guiding angle to the horizontal angle and performing the blowing operation based on the guiding direction and the guiding distance when the number of times of continuous release agent flow direction path deviation exceeds a preset maximum number of times of release agent flow direction path deviation.

[0019] By adopting the above technical solutions, in the case that the guiding angle cannot effectively adjust the release agent flow direction, the system will predict the flow direction of the release agent based on the real-time release agent flow video. If the direction is not consistent with the preset guiding direction, the system will start accumulating the number of times of release agent flow direction path deviation. When this number exceeds the preset maximum value, the system will judge that the current guiding adjustment may not achieve the expected effect, and therefore will adjust the guiding angle to the horizontal angle and perform the blowing operation based on the current guiding direction and guiding distance. This strategy ensures that even in complex and variable spraying environments, the system can respond flexibly, achieve efficient use of release agent through intelligent adjustment and optimization, and further improve the efficiency of die casting production and the quality of castings.

[0020] Optionally, the method further comprises a preset manual verification operation when the casting model does not exist, the method comprising: S10: determining a similar casting model according to the casting surface image; S11: performing a spraying operation based on the spraying position and spraying amount corresponding to the similar casting model when the similar casting model exists; S12: outputting the manual check signal when the similar casting model does not exist.

[0021] By adopting the above technical solution, when the system cannot find a model that completely matches the casting to be sprayed in the current casting model library, it will look for a similar casting model instead. The system will intelligently analyze the features of the casting surface image to determine the most likely similar casting model. If a similar casting model is found, the system will perform a spraying operation according to the spraying position and spraying amount corresponding to the model. However, if there is no similar casting model in the system, it means that the current casting may be a completely new model or its features are significantly different from known models. In this case, the system will automatically output a manual check signal. After receiving this signal, the operator needs to manually intervene to check and confirm the casting model to ensure that subsequent spraying and demolding operations can be carried out accurately. This design enhances the flexibility and adaptability of the system, enabling it to handle a wider variety of castings. At the same time, it provides an effective monitoring and checking mechanism for the operator, ensuring the stability and reliability of the entire die casting production process.

[0022] In a second aspect, the present application provides a device, which adopts the following technical solution: A device includes a workbench, the workbench is provided with a clamping assembly for clamping a finished casting in a mold, a spraying assembly for spraying release agent to the surface of the casting clamped on the clamping assembly, a blowing assembly for removing the release agent on the surface of the casting clamped on the clamping assembly, and an image capturing assembly for capturing the surface image of the casting clamped on the clamping assembly.

[0023] By adopting the above technical solution, the clamping assembly, the spraying assembly, the blowing assembly, and the image capturing assembly work together to realize the automation and intelligentization of the die casting demolding process. The clamping assembly precisely clamps the casting to ensure its stability during the spraying process; the spraying assembly accurately determines the spraying position and spraying amount based on the casting surface image obtained by the image capturing assembly and the casting model, achieving uniform spraying of the release agent; and the blowing assembly timely removes excess release agent after spraying to avoid interference with subsequent processes.

[0024] In summary, the present application has the following at least one beneficial technical effect: By combining image analysis, the casting model is accurately identified, and the key spraying area is determined through the casting model. Through means such as dynamic adjustment of blowing parameters and real-time correction of guide angles, the release agent coverage of the key spraying area is ensured to meet the standards, avoiding problems such as casting adhesion and surface damage caused by uneven coverage, and stably improving the die casting product pass rate; By identifying over-sprayed and under-sprayed areas, the excess release agent flow is guided to the under-sprayed areas by adjusting the clamping angle, achieving internal release agent distribution, reducing material waste caused by repeated spraying, and optimizing spraying parameters for continuous abnormal conditions to further reduce release agent consumption; Relying on the dynamic updating mechanism of the casting model library, combining machine learning and real-time image analysis, the spraying needs of different casting models are automatically adapted, and parameters are quickly optimized for abnormal conditions to reduce manual intervention, shorten debugging time, and improve the automation level and stability of the production line.

[0027] The present application will be further described in detail below in conjunction with the drawings and embodiments.

[0028] An embodiment of the present application discloses a device.

[0029] Based on the same inventive concept, the embodiment of the present application provides a die casting demolding method for an engine shock absorber aluminum bracket.

[0030] With reference to Figure 3 A die casting demolding method for an engine shock absorber aluminum bracket, comprising: Step S1: Obtain the surface image of the casting and the casting model.

[0031] The casting surface image refers to the image information of the surface of the casting, which is obtained by a high-resolution camera in the image capturing assembly 4 installed above the casting to obtain two-dimensional plane information, the clamping assembly 1 is responsible for clamping the casting after die casting from the mold, the spraying assembly 2 is responsible for spraying release agent to the surface of the casting, and the blowing assembly 3 is responsible for removing excess release agent on the surface of the casting. The casting model refers to identification information used to uniquely identify the specifications of the casting, which is used to associate the structural features of the casting and the key spraying area, the key spraying area refers to the area on the surface of the casting that needs to be sprayed with release agent, specifically the connection between the casting and the waste material, as well as the high-stress contact area, the complex cavity corner, and the thin-walled easy-to-stick parts of the casting surface. The structural features of the casting and the key spraying area are stored together in the casting model library through the casting model, which will be introduced in the subsequent content and will not be described here.

[0032] Step S2: Determine the corresponding spraying position according to the casting model.

[0033] The spraying position refers to a specific area on the surface of the casting that needs to be sprayed with the release agent. The system will look up the corresponding structural features and key spraying areas in the casting model library according to the casting model, so as to determine the spraying position.

[0034] Step S3: Determine the degree of die casting based on the casting surface image and the spraying position.

[0035] The degree of die casting refers to the comprehensive influence of process parameters such as pressure and temperature on different casting models during the die casting process. The way to determine the degree of die casting is actually to artificially pre-allocate the corresponding spraying amount for different casting models.

[0036] Step S4: According to the preset casting model library, query the spraying amount corresponding to the degree of die casting, and perform the spraying operation according to the spraying position and the spraying amount. After completing the spraying operation, a spraying completion signal is generated.

[0037] The casting model library refers to a mapping table that stores the casting model, key spraying area, and the mapping relationship between different degrees of die casting and spraying amount. The spraying completion signal refers to a signal indicating that the spraying operation has been successfully completed. This signal is automatically generated by the system after the spraying assembly 2 completes the spraying operation, and is used to identify that the spraying operation of the current casting has been completed.

[0038] The system will look up the corresponding spraying amount in the casting model library according to the degree of die casting of the current casting to perform the spraying operation, which refers to spraying the release agent on the key spraying area on the surface of the casting. When the spraying position and the spraying amount are determined, it means that the system has completed the analysis of the casting surface image. At this time, the system will control the spraying device to spray the release agent on the spraying position according to the spraying trajectory and speed corresponding to the spraying amount.

[0039] Step S5: In response to the spraying completion signal, acquire the spraying surface image.

[0040] The spraying surface image refers to the image information of the casting surface after the spraying operation is completed. Specifically, the system re-acquires the casting surface image in response to the spraying completion signal, and is used for subsequent analysis and evaluation of the spraying effect.

[0041] Step S6: Extract the key spraying area corresponding to the casting model from the casting model library.

[0042] Step S7: Identify the over-sprayed area based on the spraying surface image.

[0043] The over-spraying area refers to an area where the release agent is excessively covered in the spraying process. The system accurately analyzes the sprayed surface image to identify the over-spraying area. The collected sprayed surface image is denoised by Gaussian filtering, contrast enhanced and geometrically corrected to ensure that the outline of the key spraying area in the image is clear and identifiable. Then, a semantic segmentation model based on deep learning is used to separate all the areas covered with release agent from the denoised preprocessed image. The feature parameters such as the gray value, texture distribution density (the over-spraying area usually presents a more uniform high-reflective texture) and area ratio of these areas are extracted. Since the excessive coverage of the release agent forms a thicker coating, its reflection intensity of light is significantly higher than that of the normal coverage area, which appears as a continuous area with a high gray value in the image. Then, the standard spraying feature threshold corresponding to the current casting model in the casting model library is called. If the gray value of a certain area exceeds the upper limit and the continuous range exceeds the preset area, it is determined as an over-spraying area.

[0044] S80: If there is an over-spraying area in the key spraying area, determine the release agent residue amount according to the over-spraying area.

[0045] The release agent residue amount refers to the amount of release agent attached to the surface of the casting. Specifically, the gray value of the casting surface image is extracted, and the threshold segmentation method is used to accurately frame the area where the release agent is attached on the casting surface from the image. The average gray value of the area is calculated, and the extracted average gray value is substituted into the preset deep learning model to directly convert the corresponding release agent thickness. The actual area of the over-spraying area is obtained by converting the image pixel size and the actual size, and the total volume of the release agent is calculated by combining the actual area of the over-spraying area, volume = thickness x area. The total volume of the release agent is the release agent residue amount. When the key spraying area is an over-spraying area, it means that the spraying amount of the release agent in this area has exceeded the actual demand, so the release agent residue amount needs to be obtained for subsequent operations.

[0046] S81: If the release agent residue amount exceeds the preset standard release agent residue amount, control the air blowing assembly 3 to perform air blowing operation on the over-spraying area with the preset conventional air blowing parameters.

[0047] The standard release agent residual amount refers to the maximum allowable release agent residual amount that the current casting model corresponding area can accept. Specifically, it refers to the maximum allowable release agent residual amount determined in long-term production practice and process optimization for different casting models and key spraying areas, which can ensure the subsequent processing of the casting and will not cause adverse effects due to excessive residual. The conventional blowing parameters refer to the blowing operation parameters preset by the blowing assembly 3 for most conventional situations when dealing with the release agent residual in the oversprayed area, which are used to standardize the blowing process to effectively remove excess release agent. Specifically, it includes blowing pressure, blowing time, blowing distance, and blowing angle. The blowing pressure refers to the pressure of the gas output by the blowing assembly 3, the blowing time refers to the duration of the blowing assembly 3 continuously blowing the oversprayed area, the blowing distance refers to the distance between the blowing port of the blowing assembly 3 and the surface of the oversprayed area, and the blowing angle refers to the angle between the blowing direction and the surface of the casting, specifically the angle that can maximize the effect of the airflow on the residual release agent. These parameters are preset based on a large number of experiments and production experience, and are suitable for most common casting models and oversprayed situations.

[0048] Step S9: According to the spraying surface image and the key spraying area, it is determined whether there is an undersprayed area. If there is an undersprayed area, the spraying operation is repeated.

[0049] The undersprayed area refers to the area where the release agent is not sufficiently covered during the spraying process. Only the key spraying area can be classified as an undersprayed area, and the non-key spraying area, such as the waste part, does not need to be treated, and both the non-key spraying area and the key spraying area can be classified as an oversprayed area. When there is an undersprayed area, it means that the release agent coverage of the key spraying area does not meet the spraying standard, which may cause the casting to stick during the subsequent demolding process due to insufficient release agent, thereby causing damage, deformation, or difficulty in demolding. Therefore, the release agent needs to be supplemented to the undersprayed area through repeated spraying operations to ensure that the release agent coverage of the key part meets the spraying requirements of the casting model corresponding to the key spraying area, and to avoid affecting the quality and production efficiency of the die-casting product due to spraying defects.

[0050] Reference Figure 4 If there is an undersprayed area, the method of repeating the spraying operation includes: Step S90: When there is an oversprayed area, the first casting clamping state is determined based on the oversprayed area and the undersprayed area.

[0051] The first casting clamping state refers to the state of the clamping assembly 1 used to clamp the casting, specifically the clamping angle of the casting set to achieve the flow of the release agent in the oversprayed area to the undersprayed area when both the oversprayed area and the undersprayed area exist.

[0052] Step S91: Control the casting to be clamped according to the first casting clamping state for clamping adjustment, so that the release agent in the oversprayed area flows along the casting to the undersprayed area.

[0053] When there are oversprayed areas and undersprayed areas, it indicates that the spraying operation is unbalanced, while the release agent in the oversprayed area can flow to the undersprayed area to realize the reuse of the release agent and reduce the use cost of the release agent.

[0054] Step S92: Determine the current release agent residual amount based on the sprayed surface image when there is no oversprayed area.

[0055] The current release agent residual amount refers to the amount of release agent attached to the surface of the casting, specifically the amount of release agent attached to the surface of the casting when there is a critical area that is an undersprayed area and there is no oversprayed area. The system extracts the gray value by analyzing the sprayed surface image and calculates it in combination with the deep learning model. When there is a critical area that is an undersprayed area and there is no oversprayed area, it indicates that the release agent in the oversprayed area cannot be reused, at which time it is necessary to detect the release agent residual amount.

[0056] Step S93: Determine the release agent residual area when the current release agent residual amount exceeds the preset minimum adjustment amount.

[0057] The minimum adjustment amount is the minimum critical value of the release agent amount that can be adjusted, specifically the critical value for determining whether the existing release agent on the surface of the casting can be adjusted to flow to the undersprayed area for replenishment when there is no oversprayed area but there is an undersprayed area. The release agent residual area refers to the area on the surface of the casting where release agent is attached. In order not to affect the effect of spraying, the critical spraying area cannot be the release agent residual area, and the critical spraying area can be the oversprayed area.

[0058] Step S94: Determine the second casting clamping state according to the release agent residual area and the undersprayed area.

[0059] The second casting clamping state refers to the state of the clamping assembly 1 used to clamp the casting, specifically the clamping angle of the casting set to realize the flow of release agent from the release agent residual area to the undersprayed area when there is no oversprayed area but there is an undersprayed area.

[0060] Step S95: Control the casting to be clamped according to the second casting clamping state for clamping adjustment, so that the release agent in the release agent residual area flows along the casting to the undersprayed area.

[0061] When there are release agent residual areas and undersprayed areas, it indicates that the clamping state of the casting can be adjusted to allow the release agent to flow naturally from the residual area to the undersprayed area, and the casting is controlled to be clamped according to the second casting clamping state for clamping adjustment.

[0062] Step S96: repeat the spraying operation in the absence of over-sprayed areas and release agent residual areas.

[0063] When there are over-sprayed areas and release agent residual areas, it indicates that the system cannot achieve the redistribution of the release agent by adjusting the clamping state, at which time the spraying operation needs to be re-executed to supplement the release agent coverage of the under-sprayed areas.

[0064] The method also includes updating the casting model library, which includes: Step S960: accumulate the number of consecutive over-spraying when there are over-sprayed areas.

[0065] The number of consecutive over-spraying refers to the number of consecutive over-spraying for the same casting model.

[0066] Step S961: accumulate the number of consecutive under-spraying when there are under-sprayed areas.

[0067] The number of consecutive under-spraying refers to the number of consecutive under-spraying for the same casting model.

[0068] Step S962: determine the casting features based on the casting surface image when the number of consecutive over-spraying falls within a preset threshold of abnormal over-spraying or when the number of consecutive under-spraying falls within a preset threshold of abnormal under-spraying.

[0069] The threshold of abnormal over-spraying refers to the critical value of the number of consecutive over-spraying that the system determines to be abnormal, and the threshold of abnormal under-spraying refers to the critical value of the number of consecutive under-spraying that the system determines to be abnormal, which is used to identify whether the casting model or process parameters need to be adjusted. The casting features refer to a set of key information that can uniquely identify the physical properties and structural characteristics of the casting, specifically including the overall profile size (such as length, width, height, and key cross-sectional dimensions) and surface structure details (such as the number and location of holes), which are obtained through edge detection and contour recognition of the casting surface image. When the number of consecutive over-spraying reaches the corresponding threshold, it indicates that the current casting model may be incorrectly identified.

[0070] Step S963: search the casting model library based on the casting features to obtain a similar casting model.

[0071] The similar casting model refers to a casting model in the casting model library that is similar to the current casting features. Specifically, by comparing the feature parameters of the current casting with the pre-stored casting model features in the model library, a casting model queue is formed based on the similarity, and the first casting model in the casting signal queue is selected as the similar casting model.

[0072] Step S964: Perform steps S3 to S9 according to the spraying position corresponding to the similar casting model to obtain the similar under-spraying area and the similar over-spraying area.

[0073] The similar under-spraying area refers to the under-spraying area determined after spraying operation based on the spraying position and spraying amount corresponding to the similar casting model.

[0074] The similar over-spraying area refers to the over-spraying area determined after spraying operation based on the spraying position and spraying amount corresponding to the similar casting model.

[0075] Step S965: Perform spraying operation based on the similar casting model when there is no similar under-spraying area and similar over-spraying area.

[0076] When there is no similar under-spraying area and similar over-spraying area, it means that the spraying parameters corresponding to the similar casting model are highly matched with the actual needs of the current casting, which may be a casting model identification error, resulting in that the similar casting model should actually be the current casting model, and the spraying operation is performed based on the spraying parameters corresponding to the similar casting model.

[0077] In addition, if the similar under-spraying area and the similar over-spraying area still exist, an updating method of the casting model library is executed, which comprises the following steps: Step S9650: Determine the surplus release agent residual amount when the number of continuous over-spraying falls within the threshold of abnormal over-spraying.

[0078] The surplus release agent residual amount refers to the part of the release agent residual amount in the over-spraying area that exceeds the standard release agent residual amount, which is used to quantify the excessive release agent amount in the over-spraying area. The system extracts the gray value by analyzing the spraying surface image, and calculates the release agent thickness and coverage area of the region by combining the deep learning model, and then converts it into the release agent residual amount, and obtains the surplus release agent residual amount.

[0079] When the similar under-spraying area and the similar over-spraying area still exist, it means that it is not an identification error of the casting model, but a new casting model may appear, and the current parameters do not match the new casting model.

[0080] Step S96501: Determine the average release agent residual amount according to the surplus release agent residual amount.

[0081] The average release agent residual amount refers to the arithmetic mean of the surplus release agent residual amounts of all over-spraying areas in the same batch or the same model of castings where over-spraying occurs continuously. The surplus release agent residual amount of all over-spraying areas in each casting is calculated, and then the sum of these surplus amounts is divided by the total number of castings involved in the calculation to obtain the average surplus value, which is the average release agent residual amount.

[0082] Step S96502: Adjust the spraying operation corresponding to the casting model based on the average release agent residual amount and the release agent residual area, and define it as a corrected spraying operation.

[0083] The corrected spraying operation refers to the optimized spraying operation for solving the problems of continuous over-spraying and continuous under-spraying. Here, it refers to the deviation range of the spraying amount obtained by the average release agent residual amount. According to the deviation range of the spraying amount, the spraying amount adjustment value corresponding to the spraying amount mapping table in the casting model library is searched to obtain the corrected spraying operation. The spraying amount mapping table refers to a table that stores different spraying amount deviation ranges and corresponding spraying parameter adjustment values. The system automatically calculates the spraying amount parameter that needs to be adjusted by analyzing the average release agent residual amount combined with the preset rules in the spraying amount mapping table, and generates the corrected spraying operation.

[0084] Step S9651: When the number of continuous under-spraying falls within the threshold of abnormal under-spraying, adjust the spraying operation corresponding to the casting model based on the preset spraying amount rising method, and define it as a corrected spraying operation.

[0085] The spraying amount rising method refers to a method of gradually increasing the spraying amount in the case of continuous under-spraying. The system adjusts the spraying parameter according to the preset incremental gradient, for example, increasing the spraying amount by 5% each time.

[0086] Step S96511: Update the casting model library based on the corrected spraying operation and the casting model.

[0087] Replace the spraying operation corresponding to the casting model with the corrected spraying operation and store it in the casting model library.

[0088] The method for controlling the clamping adjustment of the casting includes: Step S970: When there is a first casting clamping state, determine the guide direction and guide distance based on the over-spraying area and the under-spraying area.

[0089] The guide direction refers to the direction of the release agent flow path set to guide the release agent flow to the under-spraying area. Here, it refers to the direction of the release agent flow path that guides the release agent flow from the over-spraying area to the under-spraying area. The guide distance refers to the straight-line distance between the release agent and the under-spraying area along the guide direction. When there is a first casting clamping state, it means that the current casting has both an over-spraying area and an under-spraying area, and it is possible to guide the release agent flow from the over-spraying area to the under-spraying area.

[0090] Step S971: When there is a second casting clamping state, determine the guide direction and guide distance based on the release agent residual area and the over-spraying area.

[0091] The guiding direction here specifically refers to the main flow direction of the release agent from the release agent residual area to the insufficient spraying area. When the second casting clamping state exists, it means that the current casting has both a release agent residual area and an insufficient spraying area. The system calculates the optimal guiding direction and guiding distance by analyzing the positional relationship between the release agent residual area and the insufficient spraying area, combined with the geometric characteristics of the casting surface, to ensure that the release agent can be efficiently transferred to the insufficient spraying area.

[0092] Step S972: Determine the guiding angle based on the guiding direction, guiding distance, release agent residual amount, and preset release agent flow speed.

[0093] The release agent flow speed refers to the rate at which the release agent flows on the surface of the casting. Because the release agent flow speed is different under different casting clamping states, here specifically refers to the actual moving speed of the release agent flowing from the over-sprayed area or the residual area to the insufficient spraying area under the current clamping state and the guiding direction. The release agent flow speed here is dynamically changing, with acceleration and deceleration. Here, only a reference value is used to calculate the guiding angle, and the dynamic guiding angle will be introduced in the subsequent content, which will not be traced back here. The guiding angle refers to the angle between the surface of the casting and the flow path of the release agent, which is used to ensure that the release agent can flow to the target area with the best path and efficiency. The system calculates the optimal guiding angle by analyzing the guiding direction, guiding distance, current release agent residual amount, and release agent flow speed.

[0094] Step S9720: Control the clamping adjustment of the casting based on the guiding angle.

[0095] Step S9721: Obtain real-time release agent flow video during the clamping adjustment process.

[0096] The release agent flow video refers to the real-time capture of the flow state of the release agent flowing to the insufficient spraying area during the clamping adjustment process by the high-resolution camera, and the generation of continuous video streams. These video data will be transmitted to the image processing module for analyzing the deviation between the actual flow path and the expected path of the release agent.

[0097] Step S9722: Analyze the release agent guiding speed and release agent acceleration based on the real-time release agent flow video.

[0098] The release agent guiding speed refers to the flow rate of the release agent, specifically the actual flow rate of the release agent used to flow to the insufficient spraying area in the guiding direction. The flow distance of the release agent within the interval time is obtained by collecting the position of the release agent at the preset interval time, and then the release agent guiding speed is obtained by dividing the flow distance of the release agent by the interval time. The interval time refers to the artificially preset time interval, for example, one second or two seconds. The release agent acceleration refers to the change value of the speed of the release agent in the flow process, which is used to describe the increase or decrease of the flow speed of the release agent. The release agent acceleration is obtained by differencing the speed changes of the release agent within different interval times.

[0099] Step S9723: Real-time adjustment of the guiding angle based on the release agent acceleration, and the guiding angle is defined as the dynamic guiding angle.

[0100] The dynamic guiding angle refers to the adjustment of the clamping angle of the casting in real time according to the change of the acceleration during the flow process of the release agent used to flow to the insufficient spraying area, so as to ensure that the release agent can continuously flow to the insufficient spraying area along the optimal path. The system monitors the acceleration of the release agent, and when the acceleration changes significantly, it means that the flow state of the release agent may be hindered or the guiding effect is poor. At this time, the system automatically calculates the guiding angle that needs to be adjusted according to the direction and size of the acceleration change, and controls the casting to make corresponding clamping adjustment to realize dynamic guiding.

[0101] Step S9724: Collect the current release agent residual distance when the dynamic guiding angle is the preset horizontal angle and the release agent has not entered the insufficient spraying area.

[0102] The horizontal angle refers to the guiding angle when the angle between the surface of the casting and the horizontal plane is zero.

[0103] The current release agent residual distance refers to the straight-line distance from the release agent used to flow to the insufficient spraying area to the edge of the insufficient spraying area. When the dynamic guiding angle is adjusted to the horizontal angle and the release agent still has not flowed into the insufficient spraying area, the system will accurately measure the distance between the release agent residual area and the insufficient spraying area, i.e. the current release agent residual distance, through image recognition technology. This distance value will be an important reference for subsequent adjustment of the spraying parameters or clamping state. When the dynamic guiding angle reaches the preset horizontal angle, but the release agent still has not completely flowed into the insufficient spraying area, it means that continuing to adjust the guiding angle at this time will cause deviation in the process of the release agent falling into the insufficient spraying area, and the system may not be able to make the release agent fall into the insufficient spraying area by adjusting the angle. Therefore, the current release agent residual distance is collected at this time for subsequent operation.

[0104] Step S9725: Forming the blowing parameters based on the release agent residual distance and the insufficient spraying area.

[0105] The blowing parameter refers to specific parameters for controlling the blowing assembly 3 to generate airflow to assist the flow of the release agent to the insufficiently sprayed area, including but not limited to blowing intensity, blowing angle, and blowing duration. The system calculates the corresponding blowing parameter by analyzing the relative positional relationship between the release agent residue distance and the insufficiently sprayed area. The blowing intensity is directly proportional to the release agent residue distance. To facilitate the determination of the blowing duration, the blowing intensity is a fixed blowing intensity reference value. The blowing angle is determined by the guide direction. The blowing duration is calculated based on the distance divided by the preset flow rate. The flow rate is determined by the blowing intensity reference value.

[0106] Step S9726: Control the blowing assembly 3 to perform the blowing operation based on the blowing parameter.

[0107] Step S9727: When there is no guide angle, determine the horizontal angle based on the oversprayed area, and control the casting clamping state to adjust the clamping angle according to the horizontal angle.

[0108] When there is no guide angle, it means that under the current casting clamping state, the flow of the release agent may not be effectively guided by gravity or the geometric characteristics of the casting surface, so that the release agent cannot naturally flow to the insufficiently sprayed area. By adjusting the clamping state of the casting to the horizontal angle, the release agent can be promoted to be stationary on the casting surface.

[0109] Step S9728: Reacquire the casting surface image to determine the current guide direction and the guide distance.

[0110] The current guide direction refers to the direction of the release agent after it is stationary on the casting surface to the insufficiently sprayed area.

[0111] Step S9729: Form the blowing parameter based on the current guide direction and the current guide distance, and perform step S9726.

[0112] Because the release agent cannot naturally flow to the insufficiently sprayed area at the horizontal angle, blowing operation is required.

[0113] The method further includes a method for re-determining the guide direction and the guide distance, which includes: Step S9730: When there is an oversprayed area or a release agent residue area, determine the adjustable area and accumulate the number of adjustable areas.

[0114] The adjustable area refers to the area on the casting surface where the release agent is oversprayed or excessively residual. The number of adjustable areas refers to the total number of areas on the casting surface that are identified as being adjustable. The system detects and marks all adjustable areas through image recognition technology, and accumulates the number of these areas.

[0115] Step S9731: When the number of adjustable areas is not 1, determine the corrected guide direction and the corrected guide distance based on the adjustable area.

[0116] The correction guiding direction refers to that for multiple adjustable areas, the system determines an optimal release agent flow path direction by comprehensively analyzing the positions, sizes and relative relationships with the insufficient spraying area of each area, to ensure that the release agent can flow from the adjustable area to the insufficient spraying area efficiently. The correction guiding distance refers to the actual distance of the release agent from the adjustable area to the insufficient spraying area along the correction guiding direction. When there are multiple adjustable areas, it means that the release agent of multiple adjustable areas can be combined and guided to the insufficient spraying area.

[0117] Step S9732: Determine the correction guiding angle based on the correction guiding direction and the correction guiding distance.

[0118] The correction guiding angle refers to the casting clamping angle set for multiple adjustable areas to achieve efficient flow of the release agent from these areas to the insufficient spraying area along the correction guiding direction.

[0119] Step S9733: Adjust the clamping angle based on the correction guiding angle, and execute steps S9730 to S9733.

[0120] Step S9734: When the number of adjustable areas is 1, execute steps S90 to S9729.

[0121] When the number of adjustable areas is 1, it means that there is only one adjustable area, i.e. the oversprayed area or the release agent residual area, and there is no need for complex correction guiding angle calculation. Therefore, the operation can be directly performed according to the process of steps S90 to S9729 described earlier, Step S9735: When there is no correction guiding angle, control the blowing assembly 3 to perform blowing operation on the adjustable area with normal blowing parameters.

[0122] When there is no correction guiding angle, it means that the flow of the release agent may be limited by the geometric characteristics of the casting surface, making it impossible to effectively guide the release agent to flow to the insufficient spraying area by adjusting the clamping angle. Therefore, the system controls the blowing assembly 3 to perform blowing operation on the adjustable area with normal blowing parameters to assist the release agent to flow to the insufficient spraying area.

[0123] The method also includes a method of performing blowing operation when the release agent flow cannot be guided by adjusting the guiding angle, which comprises: Step S97230: Determine the predicted release agent flow direction by referring to the real-time release agent flow video.

[0124] The predicted release agent flow direction refers to the predicted flow direction of the release agent, specifically referring to predicting the natural flow direction of the release agent under no external interference by analyzing the dynamic flow path of the release agent in the real-time release agent flow video.

[0125] Step S97231: Accumulate the number of times the continuous release agent flow path deviates when the expected release agent flow direction is not the guide direction.

[0126] The number of times the continuous release agent flow path deviates refers to the accumulation of the number of times the actual flow direction of the release agent deviates from the preset guide direction during the flow process. When the expected release agent flow direction deviates from the preset guide direction, it means that the release agent may be affected by the surface geometry of the casting, residues or other external factors, resulting in insufficient spraying to the area to be sprayed.

[0127] Step S97232: Adjust the guide angle to a horizontal angle when the number of times the continuous release agent flow path deviates exceeds the preset maximum number of times the release agent flow path deviates, and perform the blowing operation based on the guide direction and the guide distance.

[0128] The maximum number of times the release agent flow path deviates refers to a threshold value for evaluating the severity of the release agent deviating from the preset guide direction during the flow process. When the number of times the continuous release agent flow path deviates exceeds the maximum number of times the release agent flow path deviates, the system considers that adjusting the guide angle cannot effectively guide the release agent to the area to be sprayed, so the guide angle is adjusted to a horizontal angle, and the blowing parameters are calculated according to the guide direction and the guide distance at this time, and the blowing assembly 3 is controlled to perform the blowing operation to forcibly guide the release agent to the area to be sprayed.

[0129] Further comprising a method for performing a preset manual verification operation when there is no casting model, the method comprising: Step S10: Determine a similar casting model based on the casting surface image.

[0130] When there is no casting model, it means that the system cannot automatically identify the model of the current casting, which may be a known model but not identified, so it is necessary to determine a similar casting model based on the casting surface image for subsequent judgment.

[0131] Step S11: Perform the spraying operation based on the spraying position and the spraying amount corresponding to the similar casting model when there is a similar casting model.

[0132] When there is no casting model but there is a similar casting model, it means that the system can perform the spraying operation on the current casting based on the spraying position and the spraying amount information of the known similar casting model.

[0133] Step S12: Output a manual verification signal when there is no similar casting model.

[0134] The artificial check signal is a signal used to prompt artificial check the casting model. When there is no similar casting signal, it indicates that the system cannot effectively perform the spraying operation on the current casting based on the known information, therefore, the artificial check signal is output to prompt the operator to manually confirm the casting model, and adjust the spraying parameters or perform other necessary operations according to the actual situation.

Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
