Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and more specifically, to a processing control method and system for S-shaped metal diaphragms. Background Technology

[0002] S-shaped metal film boxes are a special type of packaging box, usually made of metal, with a curved shape, which differs from the traditional rectangular or square box shape.

[0003] However, due to its unique shape and hard material, low dimensional accuracy during processing can easily lead to unusable applications. Furthermore, the cutting and preparation stage in the manufacturing process of metal film boxes presents several problems. Currently, cutting relies heavily on manual control. Even with automated cutting equipment, manual verification of cut quality is still necessary. The varying experience levels of different workers result in inconsistent product quality and waste of human and material resources. More troubling is the lack of an effective feedback mechanism for the cutting process, making it difficult to detect potential problems in a timely manner and causing inconvenience to production.

[0004] Therefore, it is necessary to design a processing control method and system for S-type metal film boxes to solve the problems existing in the current technology. Summary of the Invention

[0005] In view of this, the present invention proposes a processing control method and system for S-shaped metal diaphragm boxes, aiming to solve the problems of low processing size and lack of feedback adjustment mechanism in the current processing of S-shaped metal diaphragm boxes.

[0006] In one aspect, the present invention proposes a processing control method for S-shaped metal film boxes, comprising:

[0007] A fixed blank to be processed is provided, wherein the cross-section of the blank to be processed is a U-shaped structure.

[0008] Acquire images of the cutting area, obtain cutting state parameters of the workpiece to be processed based on the images of the cutting area, and determine the cutting state of the workpiece to be processed based on the cutting state parameters;

[0009] When the workpiece is in the first cutting state, the cutting level of the current cutting area is determined according to the size data of the workpiece in the cutting area image, and the corresponding cutting edge is controlled to cut the cutting area based on the cutting level. During the cutting process, the first working unit is controlled to move away from the workpiece at preset time intervals, and the grinding unit is controlled to blow the current cutting area to acquire a clear cutting area image.

[0010] When the blank to be processed is in the second cutting state, it is determined whether to grind the cutting area based on the cutting completion degree of the cutting area image. When it is determined that the cutting area should be ground, the grinding unit is controlled to grind the cutting area.

[0011] The degree of completion of the polished metal film box is collected, and the quality of the metal film box preparation is judged based on the degree of completion.

[0012] Furthermore, when obtaining the cutting state parameters of the workpiece to be processed based on the cutting area image, the process includes:

[0013] The cutting parameters are obtained by parsing the image of the cutting area, and the cutting state parameters are calculated based on the cutting parameters.

[0014] The cutting parameters include the maximum thickness H to be cut and the area M of the region to be cut, and the cutting state parameter T1 is calculated according to the following formula:

[0015]

[0016] Wherein, H0 represents the comparison parameter of the maximum thickness to be cut according to the preset standard; M0 represents the comparison parameter of the area to be cut according to the preset standard.

[0017] Furthermore, obtaining the cutting state parameters of the workpiece to be processed based on the cutting area image also includes:

[0018] The cutting state parameter T1 is compared with the preset standard state parameter T0, and the cutting state is obtained based on the comparison result.

[0019] Based on the first comparison result, the cutting state of the cutting area is determined to be the first cutting state;

[0020] Based on the second comparison result, the cutting state of the cutting area is determined to be the second cutting state;

[0021] The first comparison result is T1 > T0, and the second comparison result is T1 ≤ T0.

[0022] Furthermore, when determining the cutting level of the current cutting area based on the dimensional data of the workpiece to be processed in the cutting area image, the following steps are included:

[0023] Obtain the average spacing width K and cutting depth S of the two cutting surfaces in the workpiece to be processed, and calculate the characteristic parameter Q1 of the workpiece to be processed according to the following formula:

[0024]

[0025] Wherein, K0 represents the preset standard interval width, and S0 represents the preset standard cutting depth;

[0026] The feature parameter Q1 of the blank to be processed is compared with the first preset feature parameter Q11 and the second preset feature parameter Q12 respectively. Q11 < Q12. Based on the comparison result, the cutting level of the current cutting area is determined, and the corresponding cutting edge is controlled to cut the cutting area based on the cutting level.

[0027] Based on the comparison result of the first feature parameter, the cutting area is determined to be of the first cutting level, and the cutting edge of the first size C1 is controlled to cut.

[0028] Based on the comparison results of the second feature parameters, the cutting area is determined to be of the second cutting level, and the cutting edge of the second size C2 is controlled to cut.

[0029] Based on the comparison results of the third feature parameter, the cutting area is determined to be of the third cutting level, and the cutting edge of the third size C3 is controlled to cut.

[0030] Wherein, the first feature parameter comparison result is Q1≥Q12, the second feature parameter comparison result is Q11≤Q1<Q12, the third feature parameter comparison result is Q1<Q11, and C1>C2>C3.

[0031] Furthermore, when determining whether to grind the cutting area based on the cutting completion degree of the cutting area image, the process includes:

[0032] Obtain the minimum interval width Kmin and minimum cutting depth Smin of the two cutting surfaces in the cutting area. Compare the minimum interval width Kmin with the preset standard interval width K0 and the minimum cutting depth Smin with the preset standard cutting depth S0. Determine whether to grind the cutting area based on the comparison results.

[0033] Under the first judgment condition, it is determined that the cutting area should be polished;

[0034] Under the second judgment condition, it is determined that the cutting area should be subjected to secondary cutting;

[0035] The first judgment condition is K0≤Kmin and S0≤Smin, and the second judgment condition is Kmin>K0 or Smin>S0.

[0036] Furthermore, when it is determined that the cutting area needs to be polished, the polishing unit polishes the cutting area, including:

[0037] The width difference ΔK is obtained based on the minimum interval width Kmin and the preset standard interval width K0, where ΔK = Kmin - K0. The depth difference ΔS is obtained based on the minimum cutting depth Smin and the preset standard cutting depth S0, where ΔS = Smin - S0. The grinding time is determined based on the width difference ΔK or the depth difference ΔS.

[0038] The polishing time is directly proportional to the width difference ΔK, and the polishing time is directly proportional to the depth difference ΔS.

[0039] Furthermore, after grinding the cutting area, when determining whether the metal film box preparation is qualified based on the degree of completion of the processing, the following steps are included:

[0040] The degree of completion includes the degree of S-shaped trajectory matching (D) and the surface finish (G). The degree of completion (W1) of the metal film box after polishing is calculated according to the following formula:

[0041]

[0042] Where D0 represents the preset standard matching degree comparison parameter; G0 represents the preset standard surface finish comparison parameter.

[0043] Furthermore, when determining whether the metal film box preparation is qualified based on the aforementioned processing completion degree, the method also includes:

[0044] The processing completion degree W1 of the metal film box is compared with the standard processing completion degree W0 to obtain the processing completion degree difference ΔW = W1 - W0. The processing completion degree difference ΔW is used to determine whether the metal film box is qualified.

[0045] Under the first determined condition, the metal film box is deemed to be of qualified preparation.

[0046] Under the second determined condition, the metal film box is determined to be unqualified in preparation;

[0047] The first determining condition is △W≥0, and the second determining condition is △W<0.

[0048] Compared with existing technologies, the advantages of this invention are as follows: By acquiring images of the cutting area in real time and analyzing cutting state parameters based on image data, high-precision control of the cutting process is ensured, reducing unusable situations caused by machining dimensional errors. Intelligent control based on cutting state and cutting grade dynamically adjusts the operation of the cutting edge, effectively improving cutting quality. Cleaning is performed at preset intervals to ensure the clarity of the cutting area image, further improving machining accuracy. Compared with traditional methods relying on human experience, utilizing automated equipment and image analysis technology reduces quality inconsistencies caused by differences in operator experience, ensuring product consistency and reliability, reducing reliance on manual inspection and operation, lowering labor costs, and avoiding resource waste due to human error. Real-time monitoring of the cutting area and grinding process allows for timely detection and adjustment of potential problems, avoiding the difficulty in timely problem detection in traditional methods, and improving production efficiency and product qualification rate.

[0049] On the other hand, this application also provides a processing control system for S-type metal diaphragm boxes, for applying the above-described processing control method for S-type metal diaphragm boxes, including:

[0050] The operating tool assembly includes a first working unit and a second working unit disposed on one side of a fixture for holding a workpiece to be processed. The first working unit is provided with a cutting assembly for cutting the workpiece to be processed to obtain a metal film. The cutting assembly is provided with a cutting disc, and the cutting disc is provided with multiple cutting edges, each of which has a different size. The second working unit is provided with a grinding unit for grinding the metal film.

[0051] The image acquisition unit includes a first image acquisition device disposed on the first working unit for acquiring images of the cutting area, and a second image acquisition device disposed on the second working unit for acquiring images of the cutting area.

[0052] The management module includes an image analysis unit, a first controller, a second controller, and a third controller that are interconnected. The image analysis unit is electrically connected to the image acquisition unit. The image analysis unit is used to acquire the cutting parameters of the cutting area image and to analyze and acquire the cutting state. The image analysis unit is also used to acquire the processing completion degree of the polished metal film box.

[0053] The first controller is connected to the first working unit and is used to determine the cutting level of the current cutting area based on the size data of the workpiece to be processed in the cutting area image when the cutting area image is in the first cutting state, and control the corresponding cutting edge to cut the cutting area based on the cutting level. During the cutting process, the first working unit is controlled to move away from the workpiece to be processed every preset time, and the grinding unit is controlled to blow the current cutting area to acquire a clear cutting area image.

[0054] The second controller is connected to the second working unit and is used to determine whether to grind the cutting area based on the cutting completion degree of the cutting area image when the cutting area image is in the second cutting state. When it is determined that the cutting area should be ground, the controller controls the grinding unit to grind the cutting area.

[0055] The third controller is used to determine whether the metal film box preparation is qualified based on the processing completion degree obtained by the image analysis unit after the cutting area is polished.

[0056] It is understandable that the above-mentioned processing control methods and systems for S-type metal film boxes have the same beneficial effects, and will not be elaborated further here. Attached Figure Description

[0059] Figure 2 This is a structural block diagram of a processing control system for an S-shaped metal film box provided in an embodiment of the present invention. Detailed Implementation

[0060] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] S-shaped metal diaphragm boxes, with their unique curved shape and metallic construction, differ significantly from traditional square or rectangular packaging boxes. However, due to their special shape and rigid material, high dimensional accuracy is required during processing; low-precision processing can easily render the product unusable. Currently, the manufacturing of S-shaped metal diaphragm boxes involves welding and casting / grinding. However, when the S-shaped metal diaphragm box is large, welding can easily cause deformation, compromising processing accuracy and resulting in a high failure rate. Casting / grinding also presents numerous problems in the cutting preparation stage. Current cutting methods rely heavily on manual control; even with automated cutting equipment, manual judgment of cutting quality is still necessary. The varying experience levels of different workers lead to inconsistent product quality and consume significant human resources. More problematic is the lack of an effective feedback mechanism for the cutting process, preventing the timely detection of potential problems and causing production inconvenience. Therefore, there is an urgent need to design a control method and system for processing S-shaped metal diaphragm boxes to address the various problems existing in current technologies.

[0062] In some embodiments of this application, see Figure 1 As shown, a processing control method for an S-type metal diaphragm box includes:

[0063] S100: Fix the blank to be processed, the cross-section of the blank to be processed is a U-shaped structure;

[0064] S200: Acquire images of the cutting area, obtain cutting state parameters of the workpiece to be processed based on the images of the cutting area, and determine the cutting state of the workpiece to be processed based on the cutting state parameters;

[0065] S300: When the workpiece is in the first cutting state, the cutting level of the current cutting area is determined according to the size data of the workpiece in the cutting area image, and the corresponding cutting edge is controlled to cut the cutting area based on the cutting level. During the cutting process, the first working unit is controlled to move away from the workpiece every preset time, and the grinding unit is controlled to blow the current cutting area to acquire a clear cutting area image.

[0066] When the blank to be processed is in the second cutting state, the cutting completion degree of the cutting area image is used to determine whether the cutting area should be polished. When it is determined that the cutting area should be polished, the polishing unit is controlled to polish the cutting area.

[0067] S400: Collect the processing completion rate of the polished metal film box, and judge whether the metal film box preparation is qualified based on the processing completion rate.

[0068] Specifically, the blank to be processed is a casting part with a roughly defined outline. The blank has a U-shaped cross-section. After cutting and grinding, the end is sealed to obtain a finished S-shaped metal film box. A fixture is used to fix the blank to the machining table, ensuring it does not move during processing. The fixture takes into account the special shape of the U-shape and holds the non-machined surfaces of the part. A high-resolution industrial camera and light source system monitor the cutting area in real time. Image processing software analyzes the acquired images, extracting image parameters to determine the cutting state of the blank. Image recognition algorithms, such as edge detection algorithms, are used to analyze the dimensional data of the cutting area in real time. Based on different cutting grades, a cutting edge is selected and the cutting area is machined. A timed control scheme is set up to pause the cutting operation at preset intervals (e.g., every 30 seconds) and control the working unit to retract. Compressed air nozzles are used to blow away cutting chips and dust, ensuring image clarity. By periodically moving the working unit away from the blank, interference between the working unit and the blank is avoided, providing a more stable and clear environment for image acquisition. The grinding unit blows away chips and debris from the cutting area, effectively improving the quality and accuracy of image acquisition. Ensuring clear images of the cutting area provides crucial reference for subsequent processing control and adjustments, enhancing the precision and stability of the machining process. Analyzing the surface finish of the cutting area determines whether the part is completely cut, and grinding is performed after cutting. After grinding, laser measurement is used to inspect the dimensions and shape of the ground metal mold box, ensuring it meets design specifications.

[0069] Understandably, the image acquisition and intelligent control scheme enables real-time monitoring and automated adjustment of the S-shaped metal film box processing, improving processing accuracy and cutting quality, reducing the impact of human factors on product consistency, optimizing the problem feedback mechanism, and effectively saving manpower and resources.

[0070] In some embodiments of this application, obtaining the cutting state parameters of the workpiece to be processed based on the cutting area image includes: parsing the cutting area image to obtain cutting parameters, and calculating the cutting state parameters based on the cutting parameters. The cutting parameters include the maximum thickness H to be cut and the area M of the area to be cut, and the cutting state parameter T1 is calculated according to the following formula:

[0071]

[0072] Where H0 represents the comparison parameter of the maximum thickness to be cut according to the preset standard. M0 represents the comparison parameter of the area to be cut according to the preset standard.

[0073] Specifically, by acquiring cutting parameters from the image of the cutting area, including the maximum thickness H to be cut and the area M to be cut, and calculating the cutting state parameter T1 according to the preset standard parameters H0 and M0, the thickness of each side of the blank to be processed can be identified through the acquired image data of the blank to be processed. By comparing the thickness data of each side with the finished product standard data, the maximum thickness to be cut can be obtained. Similarly, the area M to be cut can be obtained. The calculated state parameter T1 reflects the degree of difference between the thickness and area of ​​the area to be cut during the cutting process and the preset standard, thereby determining the actual state of the blank to be processed. At the same time, this step can also be used to monitor and analyze the blank state in real time after one or more cuts are completed.

[0074] Understandably, by monitoring cutting and status parameters in real time, precise control and full-process monitoring of the cutting process are achieved, improving machining efficiency and quality. Comparison with preset standard parameters allows for timely detection of anomalies during the cutting process, preventing product quality issues. Through calculation and analysis by the image analysis unit, the machining process is optimized, improving production efficiency and product quality stability.

[0075] In some embodiments of this application, obtaining the cutting state parameters of the workpiece to be processed based on the cutting area image further includes: comparing the cutting state parameter T1 with the preset standard state parameter T0, and obtaining the cutting state based on the comparison result.

[0076] Specifically, based on the first comparison result, the cutting state of the cutting area is determined as the first cutting state. Based on the second comparison result, the cutting state of the cutting area is determined as the second cutting state. The first comparison result is T1 > T0, and the second comparison result is T1 ≤ T0.

[0077] Understandably, by comparing cutting state parameters in real time, the actual state of the cutting area can be determined promptly and accurately, avoiding machining quality problems caused by deviations in cutting parameters. Dividing the cutting state into two categories helps in the categorized management and control of the cutting process, improving machining efficiency and product quality stability. Comparison with preset standard state parameters reduces subjectivity and error in judgment, improving the accuracy and reliability of the machining process.

[0078] In some embodiments of this application, when determining the cutting level of the current cutting area based on the size data of the workpiece to be processed in the cutting area image, the method includes: obtaining the average interval width K and cutting depth S of the two cutting surfaces in the workpiece to be processed, and calculating the feature parameter Q1 of the workpiece to be processed according to the following formula:

[0079]

[0080] Where K0 represents the preset standard interval width and S0 represents the preset standard cutting depth.

[0081] Specifically, the feature parameter Q1 of the workpiece to be processed is compared with the pre-set first preset feature parameter Q11 and the second preset feature parameter Q12, respectively. Q11 < Q12. Based on the comparison result, the cutting level of the current cutting area is determined, and the corresponding cutting edge is controlled to cut the cutting area based on the cutting level. Under the first feature parameter comparison result, the cutting area is determined to be of the first cutting level, and the cutting edge of the first size C1 is controlled to cut. Under the second feature parameter comparison result, the cutting area is determined to be of the second cutting level, and the cutting edge of the second size C2 is controlled to cut. Under the third feature parameter comparison result, the cutting area is determined to be of the third cutting level, and the cutting edge of the third size C3 is controlled to cut. Wherein, the first feature parameter comparison result is Q1 ≥ Q12, the second feature parameter comparison result is Q11 ≤ Q1 < Q12, the third feature parameter comparison result is Q1 < Q11, and C1 > C2 > C3.

[0082] Specifically, the characteristic parameter Q1 of the workpiece to be processed is calculated and compared with the first and second preset characteristic parameters. The cutting level is determined based on the comparison result, and the corresponding cutting edge is controlled to perform cutting based on the different cutting levels. During cutting, the cutting edge cuts the workpiece to be processed along a preset path to form an S-shaped groove.

[0083] It is understandable that the cutting width and depth of cut are two important parameters in the cutting process, directly affecting the contact between the cutting tool and the workpiece and the cutting effect. By analyzing and evaluating these two parameters, the cutting condition of the current cutting area can be determined, such as a large cutting depth or a small cutting width, thus judging the cutting grade of the cutting area. Different cutting strategies and cutting tools are required for different cutting grades. For example, for areas with a large cutting depth, more wear-resistant cutting tools or a reduced cutting speed are needed to ensure machining quality. For areas with a small cutting width, finer cutting tools are needed to ensure machining accuracy. Therefore, selecting appropriate cutting strategies and cutting tools according to the cutting grade can maximize machining efficiency and product quality. By calculating characteristic parameters and comparing preset parameters with the dimensional data of the workpiece to be machined, intelligent determination of the cutting grade of the cutting area is achieved, improving machining accuracy and stability. Dividing the cutting grade into multiple cases and using different sized cutting edges for different grades facilitates the classification management and control of the cutting process, improving machining efficiency and product quality stability.

[0084] In some embodiments of this application, when determining whether to grind the cutting area based on the cutting completion degree of the cutting area image, the method includes: obtaining the minimum interval width Kmin and the minimum cutting depth Smin of the two cutting surfaces in the cutting area, comparing the minimum interval width Kmin with the preset standard interval width K0, and comparing the minimum cutting depth Smin with the preset standard cutting depth S0, and determining whether to grind the cutting area based on the comparison result.

[0085] Specifically, under the first judgment condition, it is determined that the cutting area should be ground. Under the second judgment condition, it is determined that the cutting area should be subjected to secondary cutting. The first judgment condition is K0≤Kmin and S0≤Smin, and the second judgment condition is Kmin>K0 or Smin>S0.

[0086] Specifically, when the first judgment condition is met, i.e., the preset standard interval width K0 is less than or equal to the minimum interval width Kmin and the preset standard cutting depth S0 is less than or equal to the minimum cutting depth Smin, it is determined that the cutting area will be ground. When the second judgment condition is met, i.e., the minimum interval width Kmin is greater than the preset standard interval width K0 or the minimum cutting depth Smin is greater than the preset standard cutting depth S0, it is determined that the cutting area will be subjected to secondary cutting.

[0087] Understandably, by comparing the minimum interval width and minimum cutting depth of the cutting area, intelligent judgment of the cutting completion degree is achieved, avoiding product quality problems caused by insufficient or excessive cutting. Depending on different judgment conditions, flexibly choosing to grind or perform secondary cutting on the cutting area is beneficial for optimizing the machining process and improving product surface quality and machining accuracy. By comparing with preset standard parameters, the subjectivity and error of the judgment are reduced, improving the accuracy and reliability of the machining process.

[0088] In some embodiments of this application, when it is determined that the cutting area needs to be polished, the polishing unit is controlled to polish the cutting area, including: obtaining a width difference ΔK based on the minimum interval width Kmin and the preset standard interval width K0, where ΔK = Kmin - K0; obtaining a depth difference ΔS based on the minimum cutting depth Smin and the preset standard cutting depth S0, where ΔS = Smin - S0; and determining the polishing time based on the width difference ΔK or the depth difference ΔS.

[0089] Specifically, the grinding time is directly proportional to the width difference ΔK, and the grinding time is directly proportional to the depth difference ΔS.

[0090] Specifically, the width difference ΔK is compared with a pre-set first preset width difference ΔK1 and a pre-set second preset width difference ΔK2, where ΔK1 < ΔK2. Similarly, the depth difference ΔS is compared with a pre-set first preset depth difference ΔS1 and a pre-set second preset depth difference ΔS2, where ΔS1 < ΔS2. The polishing time is determined based on these comparisons. When ΔK ≤ ΔK1 or ΔS ≤ ΔS1, the polishing time is set to t1; when ΔK1 < ΔK ≤ ΔK2 or ΔS1 < ΔS ≤ ΔS2, the polishing time is set to t2; and when ΔK > ΔK2 or ΔS > ΔS2, the polishing time is set to t3, where t1 < t2 < t3. When the width difference or depth difference falls within different ranges, the longer polishing time is used.

[0091] Understandably, by comparing the polishing time with preset width and depth differences, intelligent control is achieved, allowing the polishing process to be adjusted according to actual conditions, thus improving polishing efficiency and precision. Determining different polishing times based on varying width and depth differences facilitates the implementation of appropriate polishing strategies for different situations, improving the consistency of the product surface. This method of determining polishing time avoids product quality issues caused by insufficient or excessive polishing time, ensuring the stability and reliability of the polishing effect.

[0092] In some embodiments of this application, when determining whether the metal film box preparation is qualified based on the degree of completion after grinding the cutting area, the degree of completion includes: the degree of completion includes the S-shaped trajectory matching degree D and the surface finish G, and the degree of completion W1 of the metal film box after grinding is calculated according to the following formula:

[0093]

[0094] Where D0 represents the preset standard matching degree comparison parameter. G0 represents the preset standard surface finish comparison parameter.

[0095] In some embodiments of this application, when determining whether the metal film box preparation is qualified based on the degree of completion, the method further includes: comparing the degree of completion W1 of the metal film box with the standard degree of completion W0, obtaining the degree of completion difference ΔW = W1 - W0, and determining whether the metal film box preparation is qualified based on the degree of completion difference ΔW.

[0096] Specifically, under the first determining condition, the metal diaphragm box is deemed to be of acceptable quality. Under the second determining condition, the metal diaphragm box is deemed to be of unacceptable quality. The first determining condition is ΔW≥0, and the second determining condition is ΔW<0.

[0097] Understandably, the finished product quality W1 of the metal film box is compared with the preset standard finished product quality W0 to obtain the difference ΔW, and the quality of the metal film box is determined based on ΔW. By accurately evaluating the finished product quality of the polished metal film box, comprehensive monitoring and control of product quality is achieved. Based on the preset standard finished product quality, the quality of the metal film box can be quickly determined to meet the requirements, saving human resources and time costs. Through defined judgment criteria, qualified and unqualified products can be accurately distinguished.

[0098] In the above embodiments, by acquiring images of the cutting area in real time and analyzing the cutting state parameters based on the image data, high-precision control of the cutting process is ensured, reducing unusable situations caused by machining dimensional errors. Intelligent control based on cutting state and cutting grade dynamically adjusts the operation of the cutting edge, effectively improving cutting quality. Cleaning is performed at preset intervals to ensure the clarity of the cutting area image, further improving machining accuracy. Compared to traditional methods relying on human experience, utilizing automated equipment and image analysis technology reduces quality inconsistencies caused by differences in operator experience, ensuring product consistency and reliability, reducing reliance on manual inspection and operation, lowering labor costs, and avoiding resource waste due to human error. Real-time monitoring of the cutting area and grinding process allows for timely detection and adjustment of potential problems, avoiding the difficulty in timely problem detection in traditional methods, and improving production efficiency and product qualification rate.

[0099] In another preferred embodiment based on the above embodiments, see [reference] Figure 2 As shown, this embodiment provides a processing control system for S-shaped metal diaphragms, used to apply the above-described processing control method for S-shaped metal diaphragms, including:

The first working unit is provided with a cutting assembly for cutting the workpiece to be processed to obtain a metal diaphragm.
