Description

Technical Field

[0001] This invention relates to the field of copper substrate edge polishing technology, and more particularly to an edge polishing apparatus for processing copper substrates. Background Technology

[0002] During the manufacturing process of copper substrates, due to the limitations of preliminary processing techniques such as cutting and stamping, the edges of copper substrates often have problems such as burrs, sharp edges, and unevenness. These defects not only affect the appearance quality of the copper substrate, but may also scratch other components during subsequent assembly, or even cause electrical faults such as short circuits, seriously threatening the stability and lifespan of electronic products. Therefore, it is crucial to use edge grinding equipment to perform fine processing on copper substrates. It can effectively remove edge defects, ensure the dimensional accuracy of copper substrates, and improve surface finish, thereby meeting the production requirements of high-quality electronic products. Currently, most edge grinding equipment uses universal roller brushes as the main deburring tool. Universal roller brushes, with their flexible steering performance and wide contact area, can adapt to the edges of copper substrates of different shapes and angles, achieving efficient deburring, and are therefore widely used in the industry.

[0003] The copper shavings generated during copper substrate processing are extremely fine and easily get embedded in the gaps of the universal roller brush during polishing. Over time, the accumulation of a large amount of copper shavings will change the contact surface morphology of the roller brush and reduce the polishing effect. At the same time, the oil residue left during substrate processing will adhere to the brush fibers and mix with the copper shavings to form a sticky dirt. This attached copper shavings and oil are not only difficult to clean, but will also re-contaminate the surface of the copper substrate during continuous polishing, causing secondary processing problems. This seriously affects the processing quality and production efficiency of copper substrates and has become a key bottleneck restricting the efficient production of copper substrates.

[0004] Therefore, improvements are needed to address the aforementioned issues. Summary of the Invention

[0007] The control box of the grinding device is equipped with an intelligent control component, which includes an analysis module;

[0008] The analysis module analyzes the image data transmitted from the acquisition module, determines the area of ​​copper shavings attached to the universal roller brush, and if it exceeds the threshold, generates an air jet signal and transmits the air jet signal to the execution module; it also determines the area of ​​dirt on the copper substrate surface, and if it exceeds the threshold, generates a cleaning signal and transmits the cleaning signal to the execution module; and it compares the grayscale block numbers of the attached copper shavings and the grayscale block numbers of the dirt, and presets a threshold for the number of abnormalities.

[0009] Preferably, the intelligent control component further includes a data acquisition module and an execution module;

[0010] The acquisition module acquires image data of the universal roller brush and the surface of the copper substrate, as well as data on the transmission speed of the vacuum adsorption conveyor belt and the rotation speed of the universal roller brush, and transmits the acquired data to the analysis module.

[0011] The execution module receives the jet signal and then generates high-pressure jets to clean the copper shavings attached to the universal roller brush when the abnormal marker gray block reaches the high-pressure nozzle position, based on the rotation speed of the universal roller brush.

[0012] The system receives cleaning signals, then sprays a corresponding proportion of cleaning solution based on the size of the continuous oil stains, and estimates the time when the corresponding oil stains will arrive at the sprayed cleaning solution based on the transmission speed, so that the cleaning solution can accurately clean the oil stains.

Retrieve image data when the focus-affected position is at the center of each of the two regions. Perform grayscale processing and segmentation on the image data. The maximum grayscale value in the region without focus-affected position is taken as the preset substrate grayscale value HD. jb ;

[0019] K2: The grayscale value HD of the corresponding grayscale block in the unfocused area will be used. cs With HD jb Comparison, for HD cs HD jb The grayscale blocks are marked with oil stains. The number W1 of the marked grayscale blocks is counted. The number of the marked grayscale blocks is retrieved and the number of rows and columns of the number is compared. If the number of adjacent rows or adjacent columns of the marked grayscale block is also a marked grayscale block, then the two marked grayscale blocks are determined to be continuous. The size of the continuous oil stain is equal to the number of continuous marked grayscale blocks multiplied by the area of ​​the grayscale block. The column number of the grayscale block of oil stain in the transmission direction of the vacuum adsorption conveyor belt is obtained and compared with the column number of the abnormal marked grayscale block.

[0020] K3: If two columns have the same column number, then the preset abnormal quantity threshold Y will be applied.max Set as Y md The system generates an oil stain cleaning signal and transmits it to the execution module. If no two columns have the same number, the preset abnormal quantity threshold Y is set. max Set as Y mD And generate a cleanup signal, and pass the cleanup signal to the execution module, Y md and Y mD These represent the minimum and maximum number of abnormal grayscale blocks in historical data, respectively.

[0021] Preferably, the collection assembly includes a first inclined plate fixed to the lower end of the inner wall of the cabinet, and two second inclined plates symmetrically arranged on both sides of the lower end of the first inclined plate, which are inclined towards the center. A collection box is movably provided on the bottom surface of the cabinet, and the collection box is located at the lower end of the second inclined plate and the first inclined plate.

[0022] Preferably, a driven gear located on the bottom surface of the equipment frame is coaxially fixed to the top of the first rotating shaft. A driving gear is meshed on one side of the driven gear. A second motor installed on the top surface of the cabinet is coaxially fixed to one end of the driving gear. Multiple connecting columns are arranged in a rectangular pattern around the first rotating shaft on the bottom surface of the equipment frame. A stabilizing plate is fixed to the bottom end of each connecting column. A through hole for the first rotating shaft to pass through is opened on the stabilizing plate. A bearing ring is installed on the inner wall of the through hole.

[0023] Preferably, a hot air blower is installed on the bottom surface of the equipment frame on one side of the second motor, and a hot air pipe is connected to the output end of the hot air blower. A rectangular frame is installed on the inner wall of one side of the cabinet, and an air guide plate is fixedly connected to the bottom end of the rectangular frame. The top surface of the rectangular frame is connected to one end of the hot air pipe.

[0024] Preferably, the cleaning assembly includes two fixed seats mounted on the two side frames of the vacuum adsorption conveyor belt, a rotating drum is rotatably mounted on the opposite surface of the two fixed seats, a plurality of rubber scrapers are fixedly connected at equal intervals on the outer circumference of the rotating drum, and a plurality of atomizing nozzles are equidistantly mounted on the outer wall of the rotating drum between the gaps of the rubber scrapers.

[0025] Preferably, a third motor coaxially fixed to the rotating drum is installed on one of the two fixed seats, and a rotary joint communicating with the inside of the rotating drum is installed on the other fixed seat.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. By combining the first and second inclined plates with the collection box in the collection component, copper shavings generated during polishing are easily guided and collected, improving the efficiency of copper shavings collection and enabling timely cleaning of processing waste. By combining the rubber scraper, atomizing nozzle, and rotating drum in the cleaning component, residual copper shavings and oil stains on the copper substrate surface are easily removed, improving the cleaning effect and ensuring the cleanliness of the copper substrate surface. By combining the hot air blower, hot air pipe, rectangular frame, and air guide inclined plate, hot air drying of the polished copper substrate is facilitated, improving drying efficiency and preventing moisture residue and oxidation on the copper substrate surface.

[0028] 2. The intelligent control component automatically identifies anomalies through image analysis and triggers high-pressure air nozzles to remove copper shavings embedded in the gaps of the universal roller brush, avoiding the lag of manual inspection and ensuring that the roller brush is always in good polishing condition. Grayscale processing and anomaly marking algorithms eliminate interference from light focusing, ensuring the accuracy of image analysis and providing a reliable basis for precise control. The threshold is dynamically adjusted based on the correlation of column numbering, making the cleaning action more in line with actual working conditions: when the correlation is high, early intervention is carried out to avoid secondary pollution; when the correlation is low, the cleaning frequency is reduced to reduce energy consumption and equipment wear.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1: Solving the problem of copper shavings accumulating and contaminating equipment or causing secondary adhesion to the substrate, thus affecting the continuous polishing effect;

[0039] See Figure 1-4 The present invention discloses an edge grinding device for processing copper substrates, comprising a cabinet 1, a vacuum adsorption conveyor belt 2 installed in the middle of the cabinet 1, the two ends of the vacuum adsorption conveyor belt 2 extending out of the outer walls of the cabinet 1 on both sides, a first motor for driving the vacuum adsorption conveyor belt 2 installed on one side of the outer wall of the cabinet 1, two cabinet doors symmetrically arranged on one end face of the cabinet 1, a collection component located at the lower end of the vacuum adsorption conveyor belt 2 in the cabinet 1, multiple vacuum tubes located on one side of the vacuum adsorption conveyor belt 2, the multiple vacuum tubes penetrating one side of the outer wall of the cabinet 1, a vacuum machine located at one side of the cabinet 1, the vacuum machine being connected to the vacuum tubes, an equipment frame 4 fixedly connected to the top surface of the cabinet 1, a first rotating shaft 5 rotatably mounted at one end of the bottom surface of the equipment frame 4, a connecting plate fixedly connected to the bottom end of the first rotating shaft 5, multiple electric push rods 6 arranged in a rectangular pattern on the periphery of the top surface of the connecting plate, a universal roller brush 7 fixedly connected to the telescopic end of the electric push rod 6, and a cleaning component installed on one side of the universal roller brush 7 on the vacuum adsorption conveyor belt 2.

[0040] The first motor is a SEW-MDX61B0075-5A3-4-00, which is powerful and has a stable speed; the vacuum pump is an Edwards E2M1.5, which has high pumping efficiency; the cabinet 1 is made of Q235B steel, which is strong and cost-effective; the vacuum adsorption conveyor belt 2 is made of polyester fiber, which has a smooth surface and is wear-resistant; this structure, in conjunction with the vacuum pump, can stably adsorb copper substrates; the first motor drives the vacuum adsorption conveyor belt 2, which enables continuous and efficient processing and improves production efficiency;

[0041] The collection assembly includes a first inclined plate 8 fixed to the lower end of the inner wall of the cabinet 1. Two second inclined plates are symmetrically arranged on both sides of the lower end of the first inclined plate 8, tilting towards the center. A collection box 9 is movably installed on the bottom surface of the cabinet 1, located at the lower end of the second inclined plates and the first inclined plate 8. The collection box 9 is made of PP plastic, which is highly corrosion-resistant and easy to clean. The first inclined plate 8 and the second inclined plate are made of stainless steel, with a smooth surface that does not easily retain copper shavings. This collection assembly utilizes the tilt angle of the inclined plates to allow copper shavings to automatically slide down to the collection box 9 under the action of gravity, which facilitates the collection of copper shavings and keeps the processing environment clean.

[0042] A driven gear located on the bottom surface of the equipment frame 4 is coaxially fixed to the top of the first rotating shaft 5. A driving gear is meshed on one side of the driven gear. A second motor 3 installed on the top surface of the cabinet 1 is coaxially fixed to one end of the driving gear. Multiple connecting columns are arranged in a rectangular pattern around the first rotating shaft 5 on the bottom surface of the equipment frame 4. A stabilizing plate is fixed to the bottom of the connecting columns. A through hole for the first rotating shaft 5 to pass through is opened on the stabilizing plate. A bearing ring 10 is installed on the inner wall of the through hole. The second motor 3 is a Panasonic MINASA6 series servo motor, which is highly accurate and has a fast response. The bearing ring 10 uses a 6205 deep groove ball bearing, which rotates flexibly and has low friction. This structure drives the driving gear, the driven gear, and the first rotating shaft 5 to rotate through the second motor 3, so that the universal roller brush 7 can rotate and polish. With the help of the electric push rod 6 to adjust the height and angle, it can adapt to the polishing of the edges of copper substrates of different sizes and shapes.

[0043] Example 2: Unlike Example 1, Example 2 solves the problems of residual oil on the substrate surface and moisture oxidation after cleaning;

[0044] See Figure 3-5 A hot air blower 11 is installed on the bottom surface of the equipment frame 4, located on one side of the second motor 3. The output end of the hot air blower 11 is connected to a hot air pipe. A rectangular frame is installed on the inner wall of one side of the cabinet 1. A guide plate is fixed to the bottom of the rectangular frame. The top surface of the rectangular frame is connected to one end of the hot air pipe. The hot air blower 11 can be a Siemens SR255I hot air generator, which heats up quickly and has stable airflow. This structure generates hot air through the hot air blower 11, which is blown onto the surface of the copper substrate through the hot air pipe, the rectangular frame and the guide plate. This facilitates rapid drying of the copper substrate, prevents surface moisture residue from causing oxidation, and improves the finished product quality of the copper substrate.

[0045] The cleaning assembly includes two fixed seats mounted on the two side frames of the vacuum adsorption conveyor belt 2. A rotating drum 12 is rotatably mounted on the opposite surface of the two fixed seats. Multiple rubber scrapers are equidistantly fixed to the outer circumference of the rotating drum 12. Multiple atomizing nozzles 13 are equidistantly mounted on the outer wall of the rotating drum 12 between the gaps of the rubber scrapers. The rubber scrapers are made of nitrile rubber, which is wear-resistant and has a good cleaning effect. The atomizing nozzles 13 are of the Xingcheng Spray XCPW-BB model, which atomizes evenly and is not easy to clog. The cleaning assembly uses the rotation of the rotating drum 12 to drive the rubber scrapers to scrape off copper shavings. At the same time, the atomizing nozzles 13 spray out cleaning solution to clean oil stains, which facilitates the removal of residual impurities on the surface of the copper substrate and improves the cleaning effect and the surface quality of the copper substrate. A third motor is mounted on one of the two fixed seats and is coaxially fixed to the rotating drum 12. A rotating joint 14 is mounted on the other fixed seat and communicates with the inside of the rotating drum 12. A solution pipe is connected to the rotating joint 14. One end of the solution pipe is connected to a solution tank installed on the outer wall of one end of the cabinet 1. A pump is connected between the solution tank and the solution pipe.

[0046] The third motor is a Delta ECMA-C10604RS motor, which is stable and highly reliable. The rotary joint 14 adopts an H-type rotary joint, which has good sealing performance and flexible rotation. This structure drives the drum 12 to rotate through the third motor, and the pump delivers the cleaning solution to the atomizing nozzle 13 through the solution pipe and the rotary joint 14, realizing automated cleaning, improving cleaning efficiency, and further ensuring the cleaning effect and processing quality of the copper substrate.

[0047] Example 3: Unlike Examples 1 and 2, the impact of copper shavings removal and oil stain cleaning is further reduced;

[0048] See Figure 6 A high-pressure air nozzle is added to one side of the two universal roller brushes 7 in the horizontal direction. The air jet from the high-pressure air nozzle separates the copper shavings attached to the universal roller brushes 7 from the universal roller brushes 7, reducing the impact on the polishing effect of the universal roller brushes 7. Under the action of the air jet, the copper shavings fall freely downwards, making it easy to collect them.

[0049] The control box of the grinding device is equipped with intelligent control components, which include a data acquisition module, an analysis module, and an execution module.

[0050] The acquisition module acquires image data of the universal roller brush 7 and the surface of the copper substrate, as well as data on the transmission speed of the vacuum adsorption conveyor belt 2 and the rotation speed of the universal roller brush 7, and transmits the acquired data to the analysis module.

[0051] The analysis module analyzes the image data transmitted from the acquisition module, determines the area of ​​copper shavings attached to the universal roller brush 7, and if it exceeds the threshold, generates an air jet signal and transmits the air jet signal to the execution module; it also determines the area of ​​dirt on the copper substrate surface, and if it exceeds the threshold, generates a cleaning signal and transmits the cleaning signal to the execution module; it compares the grayscale block numbers of the attached copper shavings and the grayscale block numbers of the dirt, and presets the threshold for the number of abnormalities.

[0052] A camera is installed inside the cabinet 1 to collect image data of the universal roller brush 7 and the surface of the copper substrate. The collected image data is arranged in the order of collection time and grayscale processing is performed on the collected image data. The grayscale image is divided into multiple grayscale blocks of the same size according to the size of the pixel block. The grayscale blocks are then labeled according to the row and column number of the segmented image.

[0053] On the grayscale image of the universal roller brush 7, based on the larger grayscale difference between the universal roller brush 7 and the ambient grayscale block, the range of the universal roller brush 7 on the grayscale image is marked. For each row of the range markings on the grayscale image of the universal roller brush 7 acquired at the same time, a grayscale block is randomly selected, and the grayscale value HD of the selected grayscale block is... xq Compared with the preset roller brush grayscale value HD ks Compare, if HD xq Not in HD ks Within the range of (1±k1), the grayscale value of the grayscale block is determined to be abnormal, where k1 is a scaling factor; grayscale blocks with abnormal grayscale values ​​are marked as abnormal, and the number of abnormal markings Y1 is recorded. If Y1≥Y max Then, a jet signal is generated based on the position number of the abnormal grayscale block on the grayscale image, and the jet signal is transmitted to the execution module. max Set a preset threshold for the number of anomalies;

[0054] After receiving the jet signal, the execution module generates high-pressure jet to clean the copper shavings attached to the universal roller brush 7 when the abnormal marker gray block reaches the high-pressure nozzle position, based on the rotation speed of the universal roller brush 7.

[0055] Preset roller brush grayscale value HD ks This was achieved through analysis of historical image data of the universal roller brush 7. After the new universal roller brush 7 was installed, image data acquisition was restarted. After each copper substrate was polished, the image data of the universal roller brush 7 within that time period was analyzed, and the grayscale value changes of corresponding grayscale blocks on the grayscale images of the universal roller brush 7 before and after polishing were compared to obtain the grayscale change value ΔHD. dm Calculate the mean value of the grayscale change for each grayscale block in a grayscale image. After polishing, the average grayscale value of all grayscale blocks on the 7-grayscale image of the universal roller brush is A.ha 'a' represents the number of polishing cycles. The average grayscale change values ​​of the same batch of copper substrates before and after polishing are sorted according to time sequence, and the average of the average grayscale change values ​​A1 is calculated again. Then, for the (a+1)th polishing cycle, the preset roller brush grayscale value HD... ks =A ha +A1; Record the fluctuation of the difference in the mean grayscale value of all grayscale blocks on the grayscale image of the universal roller brush before and after each grinding, calculate the mean A2 of the difference fluctuation, and compare the mean A2 with HD. ks The ratio is used as the fluctuation ratio k1;

[0056] The image data of the copper substrate is analyzed. Due to the influence of light, brightness focusing will be affected on the copper substrate. The position of focusing effect is marked. When comparing the gray values ​​of gray blocks, the gray blocks corresponding to the focusing effect position are removed. During the movement of the copper substrate, the position of focusing effect changes continuously. The moving speed of the focusing effect position is consistent with the transmission speed of the vacuum adsorption conveyor belt 2.

[0057] A line is drawn connecting the midpoints of both sides of the copper substrate to segment the region. Image data of the focal point at the center of each of the two regions are retrieved. The image data is then processed for grayscale and segmented. The maximum grayscale value in the region without focal point influence is used as the preset substrate grayscale value HD. jb ; will use the grayscale value HD of the corresponding grayscale block in the unfocused area. cs With HD jb Comparison, for HD cs HD jb The grayscale blocks are marked with oil stains. The number W1 of the marked grayscale blocks is counted, and the numbers of the marked grayscale blocks are retrieved. The number of rows and columns of the numbered grayscale blocks are compared. If the number of adjacent rows or adjacent columns of the marked grayscale block is also a marked grayscale block, then the two marked grayscale blocks are determined to be continuous. The size of the continuous oil stain is equal to the number of continuous marked grayscale blocks multiplied by the area of ​​the grayscale block. The column number of the grayscale blocks of oil stain in the transmission direction of vacuum adsorption conveyor belt 2 is obtained and compared with the column number of abnormal marked grayscale blocks. If the two column number are the same, then the preset abnormal quantity threshold Y is set. max Set as Y md The system generates an oil stain cleaning signal and transmits it to the execution module. If no two columns have the same number, the preset abnormal quantity threshold Y is set. max Set as Y mD And generate a cleanup signal, and pass the cleanup signal to the execution module, Y md and Y mD These represent the minimum and maximum values ​​of the number of abnormal grayscale blocks appearing in historical data, respectively.

[0058] Y md and Y mD These data are derived from historical data collected during long-term equipment operation, representing the minimum and maximum number of abnormal grayscale blocks encountered in the past. For example, in the past 1000 polishing cycles, the minimum number of abnormalities was 2 and the maximum was 15. Therefore, Y... md =2, Y mD =15. They are Y max The dynamic adjustment provides a quantitative basis to ensure that the threshold setting conforms to the actual production conditions—the minimum value is used when associated to quickly respond to potential pollution risks, and the maximum value is used when not associated to reduce unnecessary cleaning actions and reduce equipment wear and energy consumption;

[0059] After receiving the cleaning signal, the execution module sprays a corresponding proportion of cleaning solution according to the size of the continuous oil stains, and estimates the time point when the corresponding oil stains will arrive at the sprayed cleaning solution based on the transmission speed, so that the cleaning solution can accurately clean the oil stains.

[0060] Working Principle: When using this invention, after starting the device, the first motor drives the vacuum adsorption conveyor belt 2 to operate. The copper substrate is placed on the vacuum adsorption conveyor belt 2. The vacuum machine creates negative pressure by evacuating the vacuum adsorption conveyor belt 2 through the vacuum tube, firmly adsorbing and fixing the copper substrate. The copper substrate enters the cabinet 1 along with the vacuum adsorption conveyor belt 2. The second motor 3 drives the drive gear to rotate, which in turn drives the first rotating shaft 5 to rotate through meshing with the driven gear. This, in turn, drives the universal roller brush 7 to rotate. The electric push rod 6 adjusts the height and angle of the universal roller brush 7 according to the thickness of the copper substrate and the polishing requirements, so that it closely fits the edge of the copper substrate for polishing and deburring. The copper shavings generated during polishing are... Under the influence of gravity, the copper substrate falls and is guided by the first inclined plate 8 and the second inclined plate into the collection box 9. The polished copper substrate continues to be transported to the cleaning component. The third motor drives the rotating drum 12 to rotate, and the rubber scraper on the rotating drum 12 scrapes off the copper shavings on the surface. At the same time, the pump delivers the cleaning solution in the solution tank to the atomizing nozzle 13 through the solution pipe and the rotating joint 14. After atomization and spraying, the residual oil stains on the surface are cleaned. The cleaned copper substrate continues to move forward, and the hot air blower 11 blows hot air onto its surface through the hot air pipe, the rectangular frame and the air guide inclined plate for rapid drying. Finally, the polished, cleaned and dried copper substrate is sent out of the cabinet 1 by the vacuum adsorption conveyor belt 2, completing the entire processing process.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The system receives cleaning signals, then sprays a corresponding proportion of cleaning solution based on the size of the continuous oil stains, and estimates the time when the corresponding oil stains will arrive at the sprayed cleaning solution based on the transmission speed, so that the cleaning solution can accurately clean the oil stains.

3. The edge grinding device for processing copper substrates according to claim 1, characterized in that: The steps for the analysis module to perform anomaly analysis on the universal roller brush are as follows: S1: Arrange the acquired image data in the order of acquisition time, and perform grayscale processing on the acquired image data. After grayscale processing, the image is divided according to the size of the pixel block. The grayscale image is divided into multiple grayscale blocks of the same size, and the grayscale blocks are labeled according to the row and column number after division. S2: Based on the large grayscale difference between the universal roller brush (7) and the environmental grayscale block, the range of the universal roller brush (7) on the grayscale image is marked. For each row of the range markings on the grayscale image of the universal roller brush (7) at the same acquisition time, a grayscale block is randomly selected, and the grayscale value HD of the selected grayscale block is... xq Compared with the preset roller brush grayscale value HD ks Compare; S3: If HD xq Not in HD ks Within the range of (1±k1), the grayscale value of the grayscale block is determined to be abnormal, where k1 is a scaling factor; grayscale blocks with abnormal grayscale values ​​are marked as abnormal, and the number of abnormal markings Y1 is recorded. If Y1≥Y max Then, a jet signal is generated based on the position number of the abnormal grayscale block on the grayscale image, and the jet signal is transmitted to the execution module. max This is a preset threshold for the number of abnormalities.

4. The edge grinding device for processing copper substrates according to claim 1, characterized in that: The analysis module performs the following steps for copper substrate anomaly analysis: K1: Draw a line connecting the midpoints of the two sides of the copper substrate to segment the region. Retrieve image data when the focus-affected position is at the center of each of the two regions. Perform grayscale processing and segmentation on the image data. The maximum grayscale value in the region without focus-affected position is taken as the preset substrate grayscale value HD. jb ; K2: The grayscale value HD of the corresponding grayscale block in the unfocused area will be used. cs With HD jb Comparison, for HD cs HD jb The gray blocks are marked with oil stains. The number of gray blocks marked with oil stains, W1, is counted. The number of the gray blocks marked with oil stains is retrieved. The number of rows and columns of the number are compared. If the number of adjacent rows or columns of the gray block marked with oil stains is also a gray block marked with oil stains, then the two gray blocks marked with oil stains are determined to be continuous. The size of the continuous oil stains is equal to the number of continuous gray blocks marked with oil stains multiplied by the area of ​​the gray blocks. The number of columns of the gray blocks marked with oil stains in the transmission direction of the vacuum adsorption conveyor belt (2) is obtained and compared with the number of columns of the abnormal marked gray blocks. K3: If two columns have the same column number, then the preset abnormal quantity threshold Y will be applied. max Set as Y md The system generates an oil stain cleaning signal and transmits it to the execution module. If no two columns have the same number, the preset abnormal quantity threshold Y is set. max Set as Y mD And generate a cleanup signal, and pass the cleanup signal to the execution module, Y md and Y mD These represent the minimum and maximum number of abnormal grayscale blocks in historical data, respectively.
