Description

Technical Field

[0001] The present application relates to the technical field of building material cutting, and in particular to a method and system for cutting ceramsite concrete bricks. Background Art

[0002] Ceramic aggregate concrete bricks are ideal building materials. Usually, the bricks need to be pre-heat-formed and then cut to obtain bricks of the required specifications.

[0003] In the related art, when cutting expanded clay concrete, personnel are required to place the thermoformed and cooled expanded clay concrete blocks on a conveying roller so that the expanded clay concrete blocks and the feed port of the cutting machine are aligned before transportation. After the expanded clay concrete blocks are cut by the cutting machine, multiple expanded clay concrete bricks of smaller sizes are obtained.

[0004] With regard to the above-mentioned related technologies, the expanded clay concrete blocks before cutting are relatively large in volume and heavy in weight. It is difficult for personnel to accurately calibrate the position before moving the expanded clay concrete blocks to the expanded clay concrete cutting machine for cutting, which makes the cutting accuracy of the expanded clay concrete bricks low and cannot effectively reduce the waste expectations. Summary of the invention

[0005] In order to reduce waste and improve cutting accuracy when cutting expanded clay concrete bricks, the present application provides a method and system for cutting expanded clay concrete bricks.

[0006] In the first aspect, the present application provides a method for cutting ceramsite concrete bricks, which adopts the following technical solution:

[0007] A method for cutting ceramsite concrete bricks, comprising:

[0008] Instructing the preset conveying roller to convey each brick to be cut to the cutting device in turn according to the preset conveying parameters, and instructing the preset flat-laying adjustment mechanism to adjust the flat-laying posture of the brick;

[0009] Collect brick placement images and perform feature analysis to determine the brick placement posture. When the brick placement posture meets the preset standard placement posture, generate a brick cutting trajectory with the least residual material.

[0010] The cutting device is instructed to cut the bricks to be cut according to the brick cutting trajectory.

[0011] By adopting the above technical solution, the conveying rollers convey the bricks to be cut to the cutting device in turn and make corresponding posture adjustments so that the bricks maintain a consistent posture and are cut along the brick cutting trajectory with the least residual material, thereby reducing the slow efficiency caused by the process of personnel carrying and adjusting bricks, improving the cutting efficiency of bricks, and helping to reduce the generation of residual materials.

[0012] Optionally, when the bricks to be cut are conveyed to the cutting device, the method includes:

[0013] Performing temperature imaging analysis on the cutting surface of the brick to be cut to determine the temperature distribution image of the cutting surface;

[0014] Performing analysis based on the temperature distribution image to determine distribution areas of different distribution temperatures;

[0015] When the distribution temperature of the distribution area is higher than the preset good cutting temperature range, the minimum cooling amount corresponding to the distribution temperature in the preset temperature difference preprocessing database is matched;

[0016] The preset cooling device is instructed to spray liquid cooling on the distribution area of ​​the surface of the brick to be cut according to the minimum cooling amount, and to perform surface blowing treatment.

[0017] By adopting the above technical solution, the temperature of the cut surface of the brick is detected and analyzed when it is cut, so that the cooling device can cool with the minimum cooling amount of liquid as needed, so that the temperature of the inner and outer surfaces of the brick can be consistent, reducing the probability of local unevenness of the cut surface caused by large temperature differences during the cutting process, which helps to improve the quality of brick cutting.

[0018] Optionally, when the cutting device cuts the brick to be cut according to the brick cutting trajectory, it also includes:

[0019] Instructing a preset coolant nozzle to spray coolant on the cutting blade, and continuously collecting thermal images of the cutting blade and the brick cutting surface for analysis to determine the inner wall temperature of the brick cutting surface and the blade cutting temperature;

[0020] Calculate based on the blade cutting temperature to determine the blade temperature rise rate, and match the basic coolant adjustment parameters corresponding to the blade temperature rise rate in the preset coolant adjustment database;

[0021] Instruct the preset coolant spray device to cool the cutting blade according to the basic coolant adjustment parameters, and compare the inner wall temperature with the good cutting temperature range. When the inner wall temperature is higher than the preset good cutting temperature range, perform cooling adjustment according to the preset cooling adjustment strategy.

[0022] By adopting the above technical solution, during the cutting process of the cutting device, the corresponding basic coolant parameters are adjusted according to the temperature rise rate of the blade cutting temperature, and the blade is cooled. This can reduce the probability of the blade overheating and causing excessive wear during continuous cutting, and help extend the service life of the cutting blade.

[0023] Optionally, the cooling adjustment strategy includes:

[0024] Perform a difference calculation based on the inner wall temperature and the good cutting temperature range to determine the minimum temperature difference;

[0025] Searching for a priority cooling treatment type corresponding to the minimum temperature difference in a preset cooling treatment type table, wherein the priority cooling treatment type includes a liquid cooling treatment type and an air cooling treatment type;

[0026] The cutting surface is cooled by air blowing and cleaning device preset based on the air cooling treatment type indication, or the cutting surface is cooled by cooling liquid spraying device preset based on the liquid cooling treatment type indication, and the cutting surface temperature feedback signal is collected;

[0027] The amount of coolant is adjusted based on the cutting surface temperature feedback signal.

[0028] By adopting the above technical solution, when the temperature of the cutting surface is still high after cooling, by calculating the minimum temperature difference above the good cutting temperature range and selecting a cooling method sufficient to cool the cutting surface, such as liquid cooling or air cooling, the temperature of the cutting surface is kept balanced to facilitate obtaining a smooth cutting surface. At the same time, the cooling source required for cooling can be reduced, which helps to extend the cutting amount of bricks.

[0029] Optionally, the feedback adjustment of the coolant usage also includes:

[0030] Analyze the blade cutting temperature and spray coolant flow rate to determine the coolant dosage function;

[0031] Calculating based on the coolant usage function and a preset adjustment weight value to determine a cooling adjustment value;

[0032] When the cooling adjustment value is greater than the preset negative gain adjustment value, the cutting feed amount corresponding to the cooling adjustment value in the pre-cutting feed database is matched;

[0033] The amount of coolant is calculated using the following formula:

[0034] m.c a ·(T-T0)=Q·c·(TT a )+h·A(TT a );

[0035] The cooling adjustment value is calculated using the following formula:

[0036] P=Q·δ c ;

[0037] Where m represents the blade mass, c a represents the specific heat capacity of the blade material, T represents the current cutting blade temperature, T0 represents the initial temperature of the cutting blade, Q represents the coolant flow rate supplied, c represents the specific heat capacity of the coolant, Ta represents the temperature of the environment where the blade is located in the cutting device, h represents the convection heat transfer coefficient, A represents the surface area of ​​the blade, and δ c It represents the coolant consumption weight value, and P represents the coolant adjustment value.

[0038] By adopting the above technical solution, the specific heat capacity of the heat exchange between the cutting blade and the coolant during the cutting process is calculated and analyzed, so as to know the required amount of coolant, which helps to accurately perform feedback adjustment of the coolant dosage and reduce the occurrence of excessive consumption of coolant.

[0039] Optionally, also include:

[0040] Collect brick images after brick cutting to analyze the fracture characteristics of the cut surface to determine the fracture ratio of the cut surface;

[0041] Adjust the coolant consumption weight value in the preset negative feedback adjustment database based on the cutting surface fragmentation ratio matching;

[0042] The brick cutting track corresponding to the cutting surface is marked, and the coolant consumption weight value is negatively feedback adjusted according to the coolant consumption weight value adjustment ratio.

[0043] By adopting the above technical solution, the coolant consumption weight value is negatively feedback adjusted, so that the coolant adjustment value can be adjusted accordingly, so that the coolant usage can have a better gain effect, reducing the probability of cutting surface fragmentation caused by excessive or insufficient coolant during the cutting process.

[0044] Optionally, the brick cutting trajectory also includes:

[0045] Analyze the defect features in the brick placement image to determine the defect parameters of the cutting surface, including the defect position and defect area;

[0046] When the defect position and the cutting trajectory coincide, the corresponding flat cutting influence weight value in the preset influence weight database is matched according to the defect area;

[0047] When the flat cutting influence weight value is greater than the upper limit influence weight value, the minimum offset adjustment is performed according to the defect position and the overlapping cutting trajectory to determine the optimized cutting trajectory;

[0048] Updated optimized cutting trajectory replacement to brick cutting trajectory.

[0049] By adopting the above technical solution, the cutting trajectory is adjusted according to the defect parameters on the cutting surface of the brick, so that when the cutting device cuts the brick according to the optimized cutting trajectory, it is not easy to cause cutting cracks or damage at the defective position, thereby reducing the waste material and further improving the cutting quality of the brick.

[0050] Optionally, when determining the optimized cutting trajectory, the following is also included:

[0051] Analyze the number of cutting tracks of the optimized cutting track, and compare and analyze whether the number of optimized cutting tracks is greater than the preset upper limit of simultaneous cutting;

[0052] If not, the cutting device is instructed to adjust the cutting blades corresponding to the upper limit number of simultaneous cutting to optimize the cutting trajectory alignment, and collect cutting torque parameters during cutting;

[0053] Determine the torque reduction ratio of simultaneous cutting based on the cutting torque parameter, and match the cutting efficiency interference weight value corresponding to the torque reduction ratio in the preset efficiency interference database;

[0054] If the cutting efficiency interference weight value is greater than the preset slight interference weight value, simultaneous cutting adjustment is performed according to the preset cutting rate adjustment strategy.

[0055] By adopting the above technical solution, when the cutting device performs simultaneous cutting according to the cutting quantity corresponding to the optimized cutting trajectory, the detected cutting torque parameters are analyzed and adjusted so that the cutting device can adjust the cutting parameters, thereby improving the cutting efficiency of bricks.

[0056] Optionally, the cutting rate adjustment strategy includes:

[0057] Matching the number of efficient cutting trajectories in a preset optimal cutting database according to the number of cutting trajectories;

[0058] Calculating according to the number of cutting tracks and the preset number of efficient cutting tracks to determine the number of standby blades of the standby cutting blade;

[0059] Adjusting the state of the cutting blades based on the number of efficient cutting tracks and the number of standby blades to determine the cutting blades in the cutting state and the standby state;

[0060] When the cutting blade is in a standby state, it is adjusted to be aligned with the optimized cutting track; when the cutting blade is in a cutting state, it cuts according to the optimized cutting track, and collects an alternating signal when the cutting blade completes one optimized cutting track;

[0061] The standby state of the cutting blade is switched to the cutting state based on the alternating signal.

[0062] By adopting the above technical solution, during the cutting process, adjustments are made according to the number of cutting tracks, and blades in the cutting state and the standby state are distinguished, so that the cutting blade in the cutting state can be equipped with a larger torque for cutting, thereby improving the cutting efficiency.

[0063] In the second aspect, the present application provides a ceramsite concrete brick cutting system, which adopts the following technical solution:

[0064] A ceramsite concrete brick cutting system, comprising:

[0065] The conveying and adjusting module instructs the preset conveying rollers to convey the bricks to be cut to the cutting device in sequence according to the preset conveying parameters, and instructs the preset flat-laying adjusting mechanism to adjust the flat-laying posture of the bricks;

[0066] An image acquisition module collects brick placement images and performs feature analysis to determine the brick placement posture. When the brick placement posture meets the preset standard placement posture, a trajectory generation module generates a brick cutting trajectory with the least residual material according to the preset brick cutting specifications;

[0067] The cutting control module instructs the cutting device to cut the bricks to be cut according to the brick cutting trajectory.

[0068] By adopting the above technical solution, the bricks to be cut are transported in sequence and adjusted in position so that the bricks can be cut in a standard position and cut according to the least expected brick cutting trajectory to reduce waste generation.

[0069] In summary, the present application includes at least one of the following beneficial technical effects:

[0070] 1. The conveyor rollers convey the bricks to be cut to the cutting device in turn, and make corresponding posture adjustments so that the bricks maintain a consistent posture and are cut along the brick cutting trajectory with the least amount of residual material, thereby reducing the slow efficiency caused by the process of personnel carrying and adjusting bricks, improving the efficiency of brick cutting and helping to reduce the generation of residual material;

[0071] 2. Temperature detection and analysis is performed on the cutting surface of the brick during cutting, so that the cooling device can cool the brick with the minimum amount of liquid as needed, so that the temperature of the inner and outer surfaces of the brick can be consistent, reducing the probability of local unevenness of the cutting surface caused by large temperature differences during the cutting process, which helps to improve the quality of brick cutting;

[0072] 3. During the cutting process of the cutting device, the corresponding basic coolant parameters are adjusted according to the temperature rise rate of the blade cutting temperature, and the blade is cooled. This can reduce the probability of the blade overheating and causing excessive wear during continuous cutting, and help extend the service life of the cutting blade.

[0085] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 11 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0086] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0087] The embodiment of the present application discloses a method for cutting expanded clay concrete bricks, in which bricks to be cut are automatically transferred to a cutting device in sequence, and their corresponding postures are adjusted so that the bricks maintain a standard posture for cutting. At the same time, the least expected cutting trajectory is planned to reduce the generation of waste after the bricks are cut.

[0088] Reference Figure 1 The method flow of the ceramsite concrete brick cutting method includes the following steps:

[0089] Step S100: instruct the preset conveying roller to convey each brick to be cut to the cutting device in turn according to the preset conveying parameters, and instruct the preset flat adjustment mechanism to adjust the flat posture of the bricks; the conveying parameters include conveying time and conveying distance. When the bricks to be cut are conveyed according to the preset conveying time and conveying distance, it can make it difficult for the bricks to be cut to interfere with and contact each other when they are conveyed to the cutting device in turn, which is conducive to subsequent stable cutting.

[0090] The cutting device is a ceramsite concrete brick cutting machine equipped with a cutting blade, having a feed port and a discharge port. When the conveying roller rotates under the drive of the motor, the bricks to be cut can be conveyed to the feed port of the cutting device according to the conveying parameters, and multiple cutting blades are provided, which can be adjusted laterally at intervals so that the cutting blades can be moved to the required position for cutting. The conveying roller is rotatably connected to the conveying rail, and when the cutting is completed, the bricks in the cutting device are conveyed from the discharge port. A guide roller is provided on the adjacent side of the conveying roller to limit and guide the side walls of the bricks to be cut placed on the conveying rail so that the bricks to be cut are aligned with the feed port.

[0091] Step S101: Collecting brick placement images and performing feature analysis to determine the brick placement posture, and when the brick placement posture meets the preset standard placement posture, generating a brick cutting trajectory with the least residual material;

[0092] By setting a corresponding image acquisition camera on the outer surface of the cutting device and capturing images, the captured images are defined as brick placement images for subsequent retrieval.

[0093] Step S102: instructing the cutting device to cut the bricks to be cut according to the brick cutting trajectory.

[0094] By comparing the pre-stored brick image features with the brick placement image, the placement posture of the express outline can be obtained, and this posture is defined as the brick placement posture. The standard placement posture represents a posture that is parallel and aligned with the feed port of the cutting device. When the brick placement posture is consistent with the standard posture, the cutting trajectory is planned. Among them, the cutting target parameters are the required brick specification parameters, including the length, width, height, etc. of each brick after cutting. When planning the cutting trajectory, the maximum number of bricks that can be separated and the cutting position are calculated by calculating the width of the cutting target parameters, and the cutting position is extended in the length direction to form a brick cutting trajectory.

[0095] Reference Figure 2 , when the bricks to be cut are conveyed to the cutting device, it includes:

[0096] Step S200: performing temperature imaging analysis on the cutting surface of the brick to be cut to determine a temperature distribution image of the cutting surface;

[0097] Temperature imaging analysis is obtained by installing a corresponding temperature imaging probe on the cutting device for detection. The detected temperature imaging is defined as a temperature distribution image, which can reflect the different temperature distribution conditions on the surface of the brick to be cut. The reason for temperature imaging detection and analysis is that the brick to be cut is obtained after hot forming processing, and then the brick to be cut is transported to the cutting device for cutting in a short time, which is easy to form uneven surface temperature. The temperature difference during cutting will cause excessive friction between the blade and the brick, which is not conducive to improving the service life of the cutting blade.

[0098] Step S201: Analyze based on the temperature distribution image to determine the distribution areas of different distribution temperatures;

[0099] By dividing the areas with different temperatures, different distribution areas and distribution temperatures can be obtained for further use in subsequent analysis.

[0100] Step S202: When the distribution temperature of the distribution area is higher than the preset good cutting temperature range, the minimum cooling amount corresponding to the distribution temperature in the preset temperature difference preprocessing database is matched;

[0101] The good cutting temperature range refers to the temperature range in which the cutting stability is not easily affected by high or low temperature when the cutting blade and the brick are cutting. The staff records and stores the results after cutting experiments on bricks of different materials. Different minimum cooling amounts and corresponding distribution temperatures are stored in the temperature difference preprocessing database. When the distribution temperature is input, the corresponding minimum cooling amount can be matched and output. The minimum cooling amount is the cooling water flow required to cool the distribution temperature so that the distribution temperature is within the good cutting temperature range. In this embodiment, liquid water cooling is used to cool the surface.

[0102] Step S203: instructing the preset cooling device to spray liquid cooling on the distribution area on the surface of the brick to be cut according to the minimum cooling amount, and perform surface blowing treatment.

[0103] After finding the corresponding minimum cooling amount, the cooling nozzle sprays the surface according to the minimum cooling amount to make the surface evenly cooled. After the cooling is completed, the surface is cleaned by blowing air to reduce the impact of residual liquid on the surface. At the same time, the liquid can be guided along the direction of the airflow, which can make the brick surface get more even contact and help improve the uniformity of heat dissipation.

[0104] Reference Figure 3 When the cutting device cuts the brick to be cut according to the brick cutting trajectory, it also includes:

[0105] Step S300: instructing a preset coolant nozzle to spray coolant on the cutting blade, and continuously collecting thermal images of the cutting blade and the brick cutting surface for analysis to determine the inner wall temperature of the brick cutting surface and the blade cutting temperature;

[0106] During the cutting process, the cooling device sprays coolant on the cutting blade to reduce the temperature of the cutting blade and prevent it from generating excessive temperature when rubbing against the bricks. Thermal imaging detection and analysis is continuously performed on the cutting surface formed by the cutting blade on the brick to obtain the inner wall temperature of the cutting surface and the blade cutting temperature.

[0107] Step S301: performing calculation based on the blade cutting temperature to determine the blade temperature increase rate, and matching the basic coolant adjustment parameters corresponding to the blade temperature increase rate in a preset coolant adjustment database;

[0108] By calculating the blade cutting temperature within the calculated unit time, the blade temperature rise rate can be obtained. Different blade rise rates require the use of corresponding amounts of coolant and spraying speeds to process, so that the coolant can quickly and densely contact the cutting blade and can quickly and effectively take away the heat emitted by the cutting blade. By pre-establishing a coolant adjustment database, different blade temperature rise rates and basic coolant adjustment parameters are stored in the database. When the blade temperature rise rate is input, the corresponding basic coolant adjustment parameters are automatically matched and found. The basic coolant adjustment parameters include coolant dosage and spraying rate.

[0109] Step S302: instruct the preset coolant spraying device to cool the cutting blade according to the basic coolant adjustment parameters, and compare the inner wall temperature with the good cutting temperature range. When the inner wall temperature is higher than the preset good cutting temperature range, cooling adjustment is performed according to the preset cooling adjustment strategy.

[0110] When the cutting blade is cooled according to the basic cooling parameters, the temperature of the blade can be quickly reduced and adjusted. During the cutting process, the coolant will quickly leave the cutting blade as the cutting blade rotates, which will cause the cooling effect to decrease. The blade is further cooled and adjusted through the pre-set cooling adjustment strategy to further compensate for the reduction in cooling effect. The specific cooling adjustment strategy is further explained in the subsequent steps.

[0111] Reference Figure 4 , cooling regulation strategies include:

[0112] Step S400: performing a difference calculation based on the inner wall temperature and the good cutting temperature range to determine a minimum temperature difference;

[0113] By calculating the difference between the inner wall temperature and the good cutting temperature range, the difference between the inner wall temperature and the good cutting temperature range is obtained and defined as the minimum temperature difference.

[0114] Step S401: searching for a priority cooling treatment type corresponding to the minimum temperature difference in a preset cooling treatment type table, wherein the priority cooling treatment type includes a liquid cooling treatment type and an air cooling treatment type;

[0115] By establishing a processing type table, different minimum temperature difference ranges and corresponding priority cooling processing types are stored, including liquid cooling processing type and air cooling processing type. When cooling is performed with different priority processing types, the consumption of cooling sources can be reduced. For example, when the minimum temperature difference is small, the cooling process is performed by air cooling type. Based on the fact that the air blowing cleaning device in the cutting device needs to clean the surface of the brick when working, when air cooling is required, the air blowing cleaning device can be adjusted for cooling without the need to supplement cooling water flow.

[0116] Step S402: using an air blowing cleaning device preset based on the air cooling treatment type indication to blow air to cool the cut surface, or using a cooling liquid spraying device preset based on the liquid cooling treatment type indication to cool the cut surface, and collecting a temperature feedback signal of the cut surface;

[0117] When the air cooling treatment type is found, the preset air blowing cleaning device is instructed to blow air to cool the cutting surface. When the liquid cooling treatment type is found, the preset cooling liquid spraying device is instructed to cool the cutting surface. At the same time, the cutting surface temperature feedback signal is collected for further analysis. The temperature feedback signal indicates that the coolant is cooling the cutting surface temperature.

[0118] Step S403: performing feedback adjustment on the amount of coolant based on the cutting surface temperature feedback signal.

[0119] The amount of coolant is adjusted according to the cutting surface temperature feedback signal to keep the cutting surface temperature uniform and within a good cutting temperature range, thereby reducing the probability of uneven cutting surface caused by temperature differences.

[0120] Reference Figure 5 , the feedback adjustment of coolant usage also includes:

[0121] Step S500: Analyze according to the blade cutting temperature and the spraying coolant flow rate to determine the coolant usage function;

[0122] The cutting blade temperature can be obtained by analyzing the thermal imaging image of the cutting blade. The cutting blade temperature and the spray coolant flow rate can be obtained by establishing a change function. The specific calculation formula of the change function will be further explained in the subsequent steps.

[0123] Step S501: performing calculation based on the coolant usage function and a preset adjustment weight value to determine the cooling adjustment value;

[0124] Calculating the cooling adjustment value represents the coolant usage gain effect when the coolant is calculated according to the function. By calculating the gain effect, it can be known whether the value of the feedback adjustment is a gain or a loss, so that corresponding adjustments can be made to make the cooling effect more ideal.

[0125] Step S502: When the cooling adjustment value is greater than the preset negative gain adjustment value, the cutting feed amount corresponding to the cooling adjustment value in the pre-cutting feed database is matched;

[0126] The auxiliary gain adjustment value indicates that the cooling value brought by the coolant during the feedback adjustment of the amount is low, which may cause local fragmentation of the cutting surface due to the amount not meeting the actual needs.

[0127] The amount of coolant is calculated using the following formula:

[0128] m.c a ·(T-T0)=Q·c·(TT a )+h·A(TT a );

[0129] The cooling adjustment value is calculated using the following formula:

[0130] P=Q·δ c ;

[0131] Where m represents the blade mass, c a represents the specific heat capacity of the blade material, T represents the current cutting blade temperature, T0 represents the initial temperature of the cutting blade, Q represents the coolant flow rate supplied, c represents the specific heat capacity of the coolant, T a represents the temperature of the environment where the blade is located in the cutting device, h represents the convection heat transfer coefficient, A represents the surface area of ​​the blade, and δ c It represents the coolant consumption weight value, and P represents the coolant adjustment value.

[0132] Step S500: collecting the cutting blade temperature, and performing calculation based on the cutting blade temperature and the spraying coolant flow rate to determine a function of the blade changing with the amount of coolant used;

[0133] Step S501: Analyze based on the variation function to determine the coolant supply amount;

[0134] The change function of coolant consumption is calculated using the following formula:

[0135] m.c a ·(T-T0)=Q·c·(TT a )+h·A(TT a );

[0136] Where m represents the blade mass, c a represents the specific heat capacity of the blade material, T represents the current cutting blade temperature, T0 represents the initial temperature of the cutting blade, Q represents the coolant flow rate supplied, c represents the specific heat capacity of the coolant, T a It represents the temperature of the environment where the blade is located in the cutting device, h represents the convection heat transfer coefficient, and A represents the surface area of ​​the blade.

[0137] Reference Figure 6 , also includes:

[0138] Step S600: collecting brick images after brick cutting to perform cut surface fragmentation feature analysis to determine the cut surface fragmentation ratio;

[0139] The cut surface fragmentation feature represents the image feature of the brick fragmentation on the cut surface. By comparing and analyzing the fragmentation feature and the brick image, we can know the proportion of the area corresponding to the fragmentation feature to the cut surface. This proportion value is defined as the cut surface fragmentation ratio.

[0140] Step S601: adjusting the ratio of coolant consumption weight value in a preset negative feedback adjustment database based on the cutting surface fragmentation ratio;

[0141] The coolant consumption weight value ratio represents the influence of coolant consumption on the fragmentation of the cutting surface when the coolant is used to cool the cutting surface. By pre-establishing a feedback adjustment database, different coolant consumption weight value adjustment ratios and mutually mapped cutting surface fragmentation ratios are stored in the database. When the cutting surface fragmentation ratio is input, the corresponding coolant consumption weight value adjustment ratio is automatically found and output.

[0142] Step S602: Mark the brick cutting trajectory corresponding to the cutting surface, and perform negative feedback adjustment on the coolant consumption weight value according to the coolant consumption weight value adjustment ratio.

[0143] When different cutting surfaces are cut, they are obtained by cutting through corresponding cutting tracks. By marking the cutting tracks, the cutting parameters and coolant usage parameters of the cutting tracks can be traced back to facilitate corresponding adjustments. By replacing the coolant consumption weight value and the coolant consumption weight value adjustment ratio to form a negative feedback adjustment, the cooling adjustment value associated with the coolant usage is adjusted accordingly, so that the coolant usage is closer to reality and the probability of cracking of the cutting surface is reduced.

[0144] Reference Figure 6 , the brick cutting trajectory is also determined by:

[0145] Step S700: Analyze defect features in the brick placement image to determine defect parameters of the cut surface, where the defect parameters include defect position and defect area;

[0146] By comparing and analyzing the pre-stored defect features with the brick placement image, the defect parameters of the brick surface can be obtained, including the defect position and defect area.

[0147] Step S701: when the defect position and the cutting trajectory coincide, the corresponding leveling cutting influence weight value in the preset influence weight database is matched according to the defect area;

[0148] By comparing the defect position and the cutting trajectory, we can know whether the defect position overlaps with the cutting trajectory. If so, it means that the defect is likely to affect the cutting surface formed by the cutting trajectory. At this time, it is necessary to further analyze whether the cutting trajectory needs to be adjusted, and then analyze it by matching the flat cutting influence weight value. The flat cutting influence weight value indicates the size of the influencing factor for flat cutting of the cutting surface under the influence of the corresponding defect area. By pre-establishing an influence weight database and storing the flat cutting influence weight value and the corresponding defect area in the database, when the defect area is input, the corresponding flat cutting influence weight value is matched and output.

[0149] Step S702: when the smooth cutting influence weight value is greater than the upper limit influence weight value, a minimum offset adjustment is performed according to the defect position and the overlapping cutting trajectory to determine the optimized cutting trajectory;

[0150] The upper limit influence weight value indicates the maximum weight value when the defect area does not affect the smooth cutting. If the smooth cutting influence weight value is greater than the upper limit influence weight value, it means that the brick edge is easily damaged when cutting according to the cutting trajectory. The minimum offset indicates the distance value when the brick cutting trajectory is translated in the width direction. Under the premise that there is enough brick residue, by adjusting each cutting trajectory, the cutting trajectory and defects are avoided, a new cutting trajectory can be obtained and defined as the optimized cutting trajectory.

[0151] Step S703: Replace and update the optimized cutting trajectory with the brick cutting trajectory.

[0152] Replacing the optimized cutting trajectory with a new brick cutting trajectory can maintain a smooth cutting surface during subsequent brick cutting, which helps to improve the quality of the cut bricks.

[0153] Reference Figure 8 , when determining the optimized cutting trajectory, it also includes:

[0154] Step S800: analyzing the number of cutting tracks of the optimized cutting track, and comparing and analyzing whether the number of optimized cutting tracks is greater than a preset upper limit number of simultaneous cutting;

[0155] The cutting device is provided with a plurality of cutting blades for cutting bricks at the same time, so as to improve the cutting efficiency and make adjacent bricks less susceptible to the influence of the cutting track. The number of cutting blades is defined as the upper limit of simultaneous cutting. By comparing the upper limit of simultaneous cutting with the number of cutting tracks, it can be known whether multiple bricks can be cut at the same time.

[0156] Step S801: if not, instruct the cutting device to adjust the cutting blades corresponding to the upper limit of the number of simultaneous cutting to optimize the cutting trajectory alignment, and collect cutting torque parameters during cutting;

[0157] If the number of optimized cutting trajectories is not greater than the preset upper limit of simultaneous cutting, it means that multiple bricks can be cut at the same time. Then adjust the positions of multiple cutting blades so that the cutting blades and the optimized cutting trajectories are aligned and cutting is performed. At the same time, the torque parameters during the cutting process are collected. The torque parameters represent the value of the transmission torque of the cutting device at different times.

[0158] Step S802: determining the torque reduction ratio of simultaneous cutting based on the cutting torque parameter, and matching the cutting efficiency interference weight value corresponding to the torque reduction ratio in the preset efficiency interference database;

[0159] By analyzing the corresponding torque change value in the cutting torque parameter, the difference between the torque and the rated torque can be obtained, and the torque reduction ratio can be calculated. The torque reduction ratio can feedback the cutting efficiency of bricks. By pre-establishing an efficiency interference database and storing different torque reduction ratios, when the torque reduction ratio is input, the corresponding cutting efficiency interference weight value is automatically found and output.

[0160] Step S803: If the cutting efficiency interference weight value is greater than the preset slight interference weight value, simultaneous cutting adjustment is performed according to the preset cutting rate adjustment strategy.

[0161] The slight interference weight value represents the weight value that has less interference on the cutting efficiency. When the cutting efficiency interference weight value is greater than the preset slight interference weight value, it means that the cutting efficiency is low at this time. Then it is adjusted according to the pre-set cutting rate adjustment strategy. The specific adjustment steps will be further elaborated in the following.

[0162] Reference Figure 8 , cutting rate adjustment strategies include:

[0163] Step S900: matching the number of efficient cutting trajectories in a preset optimal cutting database according to the number of cutting trajectories;

[0164] The number of efficient cutting tracks indicates the number of blades that can quickly cut bricks. When cutting with different track cutting numbers, the number of simultaneous cutting can be reduced when cutting according to the corresponding number of efficient cutting tracks. For example, when the number of tracks to be cut is 8 and the number of efficient cutting tracks is two, less torque is used compared to three efficient cutting tracks, and a stable torque supply can be maintained during fast cutting. By pre-establishing the optimal cutting database and storing different numbers of cutting tracks and corresponding numbers of efficient cutting tracks in the database, when the number of cutting tracks is input, the corresponding number of efficient cutting tracks is automatically matched and output for call.

[0165] Step S901: Calculating according to the number of cutting tracks and the preset number of efficient cutting tracks to determine the number of standby blades of the standby cutting blades;

[0166] The difference between the number of cutting tracks and the number of efficient cutting tracks is calculated, and the calculated value is defined as the number of standby blades.

[0167] Step S902: adjusting the state of the cutting blades based on the number of efficient cutting tracks and the number of standby blades to determine the cutting blades in the cutting state and the standby state;

[0168] The cutting state blade is a blade that performs cutting work, and the standby state blade is a cutting blade that is in standby state. The blades in the standby state are marked to distinguish between blades in two different states.

[0169] Step S903: when the cutting blade is in the standby state, the cutting blade is adjusted to be aligned with the optimized cutting track; when the cutting blade is in the cutting state, the cutting is performed according to the optimized cutting track, and an alternating signal when the cutting blade completes one optimized cutting track is collected;

[0170] Since the blade in the standby state does not cut, and the blade in the cutting state will generate corresponding heat and wear after cutting for a certain period of time, the blades in the two states are replaced and cut after being aligned according to the optimized cutting trajectory, so that different blades can maintain a good utilization rate and reduce the probability of a single blade being quickly worn out due to long-term operation and needing to be replaced. Among them, the alternating signal is a prompt signal sent when the blade in the cutting state completes the operation of the current optimized cutting trajectory.

[0171] Step S904: Switching the cutting blade from the standby state to the cutting state based on the alternating signal.

[0172] After the alternating signal is collected, the corresponding cutting blade is instructed to switch states, so that the cutting blade in the standby state performs the cutting operation.

[0173] Based on the same inventive concept, an embodiment of the present invention provides a ceramsite concrete brick cutting system, comprising:

[0174] The conveying and adjusting module instructs the preset conveying rollers to convey the bricks to be cut to the cutting device in sequence according to the preset conveying parameters, and instructs the preset flat-laying adjusting mechanism to adjust the flat-laying posture of the bricks;

[0175] An image acquisition module collects brick placement images and performs feature analysis to determine the brick placement posture. When the brick placement posture meets the preset standard placement posture, a trajectory generation module generates a brick cutting trajectory with the least residual material according to the preset brick cutting specifications;

[0176] The cutting control module instructs the cutting device to cut the bricks to be cut according to the brick cutting trajectory.

[0177] Reference Fig.10 and Fig.11 In this embodiment, when cutting ceramsite concrete bricks, the cutting system includes a conveying rail 1 and a cutting device 2. A plurality of conveying rollers 11 are provided on the conveying rail 1. The conveying rollers 11 are connected to a servo motor to obtain a transmission torque, thereby transmitting the bricks to be cut toward one side of the cutting device 2. The servo motor receives a PLC control signal to move, thereby being able to transport the bricks to be cut in intervals according to a certain order and time. The cutting device 2 is a concrete cutting machine, which is provided with a feed port 21 and a discharge port 22, and forms a cutting chamber 23. The bricks to be cut enter the cutting chamber 23 from the feed port 21, and a plurality of small bricks are obtained under the cutting of the cutting blade, and then are transmitted from the discharge port 22. The cutting chamber 23 is also provided with a corresponding coolant nozzle 24 and an airflow cleaning module, which can cool the brick surface and the cutting blade according to the received signal.

[0178] In this embodiment, when performing thermal imaging detection and image detection, the thermal imaging detection probe 25 and the image acquisition camera 26 are arranged in the cutting chamber 23, and a certain distance is maintained between the thermal imaging detection probe 25 and the cutting blade, so that the detection of the thermal imaging detection probe 25 is not affected by the splashing of waste chips generated during the cutting process, thereby improving the detection accuracy and stability. It can be arranged at the desired position.

[0179] In addition, the conveyor rail 1 is provided with a guide roller 12 in the loading area of ​​the bricks to be cut, so that the side wall of the bricks can be limited and guided. In order to allow the bricks to lie flat on the conveyor roller 11, a buffer adjustment rod 13 is also provided on the side of the conveyor rail 1 close to the feed port 21. The buffer adjustment rod 13 is hinged to the conveyor rail 1 and is kept upright by the torsion of the elastic spring. When the bricks to be cut contact the buffer adjustment rod 13, they fall toward the feed port 21. At this time, the bricks to be cut continue to move toward the front side and flatten the buffer adjustment rod 13, so that the buffer adjustment rod 13 does not hinder the movement of the bricks to be cut. When the bricks to be cut enter the cutting chamber 23, the buffer adjustment rod resumes its upright state.
