Abstract
Description
Technical Field
[0001] The present application relates to the field of glass processing technology, and in particular to a glass cutting control method, device and equipment. Background Art
[0002] In the traditional glass production method, a fixed size of cuts is usually made on a large piece of glass to be cut according to the glass order, so as to obtain cut glass of a single size. That is, on the traditional glass production line, the cut glass that is continuously flowing out is usually cut in a fixed size.
[0003] However, this fixed cutting method for glass has some problems. For example, due to the fixed cutting method, the utilization rate of the high-quality areas in the glass to be cut is limited, and the bad areas cannot be eliminated, resulting in a lot of high-quality areas being wasted and bad products being mixed into qualified products, resulting in resource loss and low product yield. Secondly, due to the fixed cutting method, only one size of glass can be produced in the same time period. If the glass order includes glass of different sizes, it is necessary to wait until the production of the previous batch of glass of the same size is completed before the production of the next size of glass can be carried out. The flexibility is poor and affects the efficiency of the supply chain. Summary of the invention

[0067] Optionally, the devices involved in the application scenario also include cameras, etc. The electronic device can be communicatively connected with the camera, the camera obtains a surface image of the glass to be cut, and sends the surface image to the electronic device, and the electronic device performs quality inspection on the glass to be cut based on the surface image to obtain a quality inspection result.
[0068] And the cutting tools in this application scenario may include longitudinal cutting knives, cross cutting knives, and may also include a robot for stacking the cut glass, etc.
[0069] Combine the following Figure 1 For application scenarios, refer to Figure 2 To describe the glass cutting control method provided according to an exemplary embodiment of the present application.
[0070] Figure 2 FIG. 1 is a flow chart of a glass cutting control method provided by an embodiment of the present application. Figure 2 As shown, the method in the embodiment of the present application may include:
[0071] Step 201 : Perform quality inspection on the glass to be cut to obtain a quality inspection result of the glass to be cut.
[0072] In this embodiment, the glass to be cut is a whole large piece of glass. Cutting is performed on the glass to be cut to obtain a plurality of cut glasses that meet the order requirements. The quality inspection results include high-quality areas and poor areas on the glass to be cut, wherein the poor areas are areas on the glass to be cut that include defects such as cracks, bubbles, impurities, surface scratches, and uneven colors, and the high-quality areas are areas on the glass to be cut that do not include defects, that is, areas on the glass to be cut other than the poor areas. The high-quality areas can be effectively used to produce qualified glass products.
[0073] In some embodiments, when the quality inspection results of the glass to be cut are obtained, a surface image of the glass to be cut can be obtained, and the glass to be cut can be divided into multiple regions based on the surface image. For each region, it is detected whether there are defects in the region. If there are defects in the region, the region is determined to be a poor region. If there are no defects in the region, the region is determined to be a high-quality region.
[0074] Optionally, in this embodiment, a laser sensor such as a laser rangefinder can be used to obtain the size of the glass to be cut, such as thickness, width and length. In addition, a camera can be used to obtain a surface image of the glass to be cut, and the glass to be cut can be divided into multiple areas based on the surface image, such as multiple areas of the same size, and image recognition can be performed on each area based on image recognition technology such as edge detection and template matching to detect whether there are defects in the area, and then determine the quality status of the area, and determine the area as a high-quality area or a poor area. A coordinate system can be constructed based on the glass to be cut, and the specific position of each high-quality area or poor area in the glass to be cut can be represented by coordinates.
[0075] Step 202: Obtain a glass order, determine the priority of each glass in the glass order, and determine the target glass according to the priority of each glass.
[0076] Exemplarily, a glass order may provide multiple orders to a customer, and each glass order includes information data of the required glass, such as the size and quality requirements of each glass, as well as the quantity. Among them, glass of different sizes may have different uses, and therefore correspond to different quality requirements. For example, a certain size of glass used for automotive glass has higher quality requirements than another size of glass used for architectural glass. Quality requirements may include high, medium, low or more levels, which are marked for each glass in the glass order. The same glass order may also include glass of different sizes and quality requirements. For example, a certain glass order includes 10 pieces of glass with high quality requirements and a size of 100×200mm, 5 pieces of glass with medium quality requirements and a size of 100×200mm, and 10 pieces of glass with high quality requirements and a size of 150×300mm.
[0077] In some embodiments, when determining the priority of each glass in a glass order, the quality grade of each glass can be determined according to the quality requirements of each glass in the glass order, and the priority of each glass can be determined based on the size, quality grade, size coefficient and quality coefficient of each glass.
[0078] After research, it is found that glass with large size and high quality grade is usually considered to be more important. Therefore, in this embodiment, the priority of each glass is determined based on the size and quality grade of each glass in the glass order, and the glass with high priority is cut first. The quality grade can be expressed as a numerical value and is proportional to the quality requirement. That is, the higher the quality requirement of the glass, the higher the corresponding quality grade value. The expression of glass priority is:
[0079] P i =w s S i +wq Q i
[0080] Where P i is the priority of the i-th glass, S i and Q i are the size and quality grade of the i-th glass, w s and w q are the size coefficient and quality coefficient respectively. Here, the i-th type of glass is the glass with the same size and the same quality requirements in the same glass order. In this way, the glass of the same size may have different corresponding priorities due to different quality grades.
[0081] Exemplarily, when determining the target glass according to the priority of each glass, each glass can be sorted according to the priority of each glass to obtain a sorting result, and a preset number of glasses with the highest priority in the sorting result are used as the target glass, and the sorting result is updated, and the updated sorting result is used as the sorting result.
[0082] In this embodiment, the glasses are sorted according to the priority, such as sorting the glasses in descending order of priority, to obtain the sorting result. Then, the preset number of glasses with the highest priority is used as the target glass, and the glasses to be cut are subsequently cut based on the target glass to obtain the cut glass corresponding to the target glass, that is, the target glass is cut preferentially. Here, the preset number is an integer greater than 1, and can be set as needed, such as 1, 2, or 3.
[0083] In this way, the priority is determined according to the size and quality level of each glass, so that the glass with large size and high quality level is cut first, which improves the flexibility of glass production and improves the efficiency of the supply chain. In addition to considering the size and quality level of the glass, the priority of each glass can also be determined by considering the delivery time of the glass, the special requirements marked in the glass order, etc., which will not be repeated here.
[0084] Step 203: Determine a cutting plan and a cutting path corresponding to the target glass according to the quality inspection result, the target glass and the glass to be cut.
[0085] In this embodiment, the cutting scheme corresponding to the target glass is the overall cutting plan for the target glass, including the specific cutting position of the target glass on the glass to be cut. As mentioned above, a coordinate system can be constructed based on the glass to be cut, and the specific cutting position included in the cutting scheme can be expressed by coordinates. If there is one target glass, the cutting scheme is the cutting scheme for this one target glass. If there are multiple target glasses, the cutting scheme is the cutting scheme for the multiple target glasses. In order to improve the utilization rate of the high-quality area and improve production flexibility, the number of target glasses is usually not too large, that is, the preset number will not be too large.
[0086] The cutting path corresponding to the target glass is the actual movement trajectory of the tool when cutting the glass to be cut, including the cutting order and direction, etc. It is the specific execution details during the implementation of the cutting plan. Its focus is on how to complete the cutting based on the cutting plan efficiently and accurately.
[0087] As can be seen from the foregoing, the quality inspection results include high-quality areas and poor areas on the glass to be cut. In some possible implementations, when determining the cutting scheme and cutting path corresponding to the target glass, this embodiment can determine the cutting scheme corresponding to the target glass based on the high-quality area, the target glass and the glass to be cut, and determine the cutting path of the target glass based on the cutting scheme and the poor area.
[0088] In this embodiment, when determining the cutting scheme corresponding to the target glass, the utilization rate of the high-quality area is mainly considered, with the goal of including as many high-quality areas and fewer bad areas as possible in the cutting scheme, effectively utilizing the high-quality areas and reducing the waste of the high-quality areas. When determining the cutting path corresponding to the target glass, the cutting path is mainly considered to avoid the bad areas as much as possible, and the cutting cost is considered to prevent the tool from passing through the bad areas during cutting, which may cause adverse effects on the quality of the glass to be cut due to defects in the bad areas.
[0089] In some embodiments, when determining a cutting plan corresponding to the target glass, the following steps A1 to A4 may be performed.
[0090] A1. Generate multiple initial cutting plans based on the target glass and the glass to be cut.
[0091] A2. Calculate the first fitness corresponding to each initial cutting scheme respectively, and determine a plurality of candidate cutting schemes based on the first fitness corresponding to each initial cutting scheme.
[0092] A3. Perform crossover and mutation on each candidate cutting scheme, and use the cutting scheme after crossover and mutation as the initial cutting scheme.
[0093] A4. Repeat the steps of calculating the first fitness corresponding to each initial cutting scheme until the first stop condition is reached, and use the cutting scheme with the best first fitness among the initial cutting schemes as the cutting scheme corresponding to the target glass.
[0094] The first fitness includes the utilization rate of the high-quality areas, which is determined based on the ratio of the number of high-quality areas remaining on the glass to be cut to all high-quality areas after the glass to be cut is cut according to the corresponding initial cutting scheme.
[0095] In this embodiment, firstly, according to the size of the target glass and the size of the glass to be cut, starting from one side of the glass to be cut, a plurality of initial cutting schemes are randomly generated. Considering that the cutting scheme should include as many high-quality areas as possible, this embodiment uses the utilization rate of the high-quality areas as the first fitness of the cutting scheme.
[0096] Among them, the expression of the utilization rate of the high-quality area is:
[0097] Y=1-X s / X z
[0098] In the formula, Y is the utilization rate of high-quality areas, X is s X is the number of high-quality areas remaining on the glass to be cut after the glass to be cut is cut according to the corresponding initial cutting plan. z It is the number of all high-quality areas on the glass to be cut before any cutting is performed (ie, the original glass to be cut).
[0099] In this way, after calculating the first fitness of each initial cutting scheme, the first number of initial cutting schemes with the largest first fitness are taken as candidate cutting schemes, that is, multiple excellent individuals are selected based on the first fitness, and the above multiple excellent individuals are crossover and mutation to generate multiple new individuals, that is, the crossover and mutation cutting schemes are obtained. After that, the crossover and mutation cutting schemes are used as the initial cutting schemes, and the steps of calculating the first fitness corresponding to each initial cutting scheme are re-executed, that is, iteration is performed until the first stop condition is reached.
[0100] Optionally, the first stop condition may be that the number of iterations reaches a first number threshold, or the first fitness is greater than a first fitness threshold. Afterwards, the cutting scheme with the largest first fitness among the initial cutting schemes in the last iteration is used as the cutting scheme corresponding to the target glass, that is, the cutting scheme with the largest utilization rate of the high-quality area is used as the cutting scheme corresponding to the target glass. As mentioned above, a coordinate system can be constructed based on the glass to be cut, and the specific cutting position included in the cutting scheme corresponding to the target glass can be expressed by coordinates.
[0101] In this embodiment, a genetic algorithm (GA) is used to determine the cutting scheme corresponding to the target glass with the utilization rate of the high-quality area as the first fitness, and the specific steps are not repeated here. Of course, this embodiment can also use other algorithms such as simulated annealing algorithm (SA), particle swarm optimization (PSO) and other algorithms to determine the cutting scheme corresponding to the target glass, which is not specifically limited here.
[0102] In this embodiment, the utilization rate of high-quality areas is used as the adaptability, which can ensure that the cutting plan corresponding to the target glass finally determined includes as many high-quality areas and fewer defective areas as possible, thereby effectively utilizing the high-quality areas, reducing the waste of high-quality areas and the mixing of defective products into qualified products, and improving product yield.
[0103] In some embodiments, when determining the cutting path of the target glass, the following steps B1 to B4 may be performed.
[0104] B1. Generate multiple initial cutting paths based on the current position of the tool and the cutting plan.
[0105] B2. Calculate the second fitness corresponding to each initial cutting path respectively, and determine a plurality of candidate cutting paths based on the second fitness corresponding to each initial cutting path.
[0106] B3. Cross and mutate each candidate cutting path, and use the cross and mutated cutting path as the initial cutting path.
[0107] B4. Repeat the steps of calculating the second fitness corresponding to each initial cutting path until the second stop condition is reached, and use the cutting path with the best second fitness among the initial cutting paths as the cutting path corresponding to the target glass.
[0108] The second fitness includes a path cost. The path cost is determined based on the cutting distance cost, cutting time cost and quality cost generated when cutting according to the corresponding initial cutting path; the quality cost is determined according to the penalty value of the cutting path passing through the bad area.
[0109] In this embodiment, when the glass to be cut is cut for the first time, the current position of the tool can be determined based on the initial position of the tool. When the glass to be cut is cut subsequently, the current position of the tool is the position where the tool stops after cutting the previous target glass. According to the current position of the tool and the cutting plan, multiple initial cutting paths are randomly generated, and the initial cutting path must pass through the specific cutting position included in the cutting plan. Considering that the cutting path should avoid bad areas as much as possible and the cutting cost should be reduced as much as possible, this embodiment uses the path cost as the second fitness of the cutting path. Among them, the expression of the path cost is:
[0110] C=C l +C t +C q
[0111] In the formula, C is the path cost, C l is the cutting distance cost, C t is the cutting time cost, C q For quality cost.
[0112] Optionally, the cutting distance cost is the product of the total distance the tool moves and the unit distance cost when cutting according to the corresponding initial cutting path, and the total distance the tool moves should be minimized. The cutting time cost is the product of the cutting time and the unit time cost when cutting according to the corresponding initial cutting path, wherein the cutting time is determined by the total distance the tool moves, the tool moving speed, and the cutting preparation time, for example, the cutting time is equal to the sum of the ratio of the total distance the tool moves to the tool moving speed and the cutting preparation time. Here, the tool moving speed and the cutting preparation time can be fixed values or can be determined based on the target glass. The quality cost is related to the bad area. In this embodiment, a penalty value is assigned to each bad area. The quality cost is the sum of the penalty values corresponding to each bad area passed by the initial cutting path. The cutting path passing through the bad area should be minimized.
[0113] In this way, after calculating the second fitness of each initial cutting path, the second number of initial cutting paths with the smallest second fitness are taken as candidate cutting paths, that is, multiple excellent individuals are selected based on the second fitness, and the above multiple excellent individuals are cross-crossed and mutated to generate multiple new individuals, that is, the cross-crossed and mutated cutting paths are obtained. After that, the cross-crossed and mutated cutting paths are used as the initial cutting paths, and the steps of calculating the second fitness corresponding to each initial cutting path are re-executed, that is, iteration is performed until the second stop condition is reached.
[0114] Optionally, the second stop condition may be that the number of iterations reaches a second number threshold, or the second fitness is less than a second fitness threshold. Afterwards, the cutting path with the smallest second fitness among the initial cutting paths in the last iteration is used as the cutting path corresponding to the target glass, that is, the cutting path with the smallest path cost is used as the cutting path corresponding to the target glass.
[0115] In this embodiment, a genetic algorithm is used to determine the cutting path corresponding to the target glass with the path cost as the second fitness, and the specific steps are not repeated here. Of course, this embodiment can also use other algorithms such as simulated annealing algorithm, particle swarm algorithm, etc. to determine the cutting path corresponding to the target glass, or use A* algorithm to determine the cutting path corresponding to the target glass, which is not specifically limited here.
[0116] In this embodiment, the path cost is used as the fitness, wherein the path cost includes the quality cost determined according to the penalty value of the cutting path passing through the bad area, which can ensure that the cutting path corresponding to the target glass finally determined avoids passing through the bad area as much as possible and reduces the cutting cost as much as possible, thereby preventing the tool from passing through the bad area during cutting, which may cause adverse effects on the quality of the glass to be cut due to defects in the bad area, thereby improving the product yield.
[0117] Step 204, cutting the glass to be cut according to the cutting scheme and the cutting path, and taking the remaining glass to be cut after cutting as the glass to be cut; repeating the step of determining the target glass according to the priority of each glass until the cutting stop condition is met.
[0118] In this embodiment, after the cutting scheme and cutting path of the target glass are determined, the glass to be cut is cut based on the cutting scheme and cutting path to obtain the cut glass corresponding to the target glass. After that, the steps of determining the target glass according to the priority of each glass, determining the cutting scheme and cutting path corresponding to the target glass according to the quality inspection result, the target glass and the glass to be cut, and cutting the glass to be cut according to the cutting scheme and cutting path are re-executed until the cutting stop condition is met.
[0119] Optionally, the cutting stop condition may include that the glass to be cut can no longer be effectively cut, or that the glass in all glass orders has been cut. The glass to be cut can no longer be effectively cut, which means that the size of the glass to be cut can no longer meet the size of the target glass, and the target glass cannot be obtained no matter how the glass to be cut is cut. At this time, the glass to be cut can be reselected, and based on the reselected glass to be cut and the unfinished glass in the glass order, the glass cutting control method provided in the embodiment of the present application is executed.
[0120] In some embodiments, before cutting the glass to be cut according to the cutting plan and the cutting path, the quality of the glass to be cut can be re-inspected to obtain a new quality inspection result of the glass to be cut, and it is determined whether the new quality inspection result is consistent with the quality inspection result. If the new quality inspection result is consistent with the quality inspection result, the step of cutting the glass to be cut according to the cutting plan and the cutting path is executed. If the new quality inspection result is inconsistent with the quality inspection result, the new quality inspection result is used as the quality inspection result, and the step of determining the cutting plan and cutting path corresponding to the target glass is executed according to the quality inspection result, the target glass and the glass to be cut.
[0121] In the process of cutting the glass to be cut, new defective areas may be generated in the glass to be cut due to unexpected circumstances. Therefore, in order to ensure the quality of the final glass product and avoid waste of high-quality areas, the quality of the glass to be cut can be re-inspected according to the cutting plan and cutting path before cutting each time, and based on the consistency between the new quality inspection result and the previous quality inspection result, it is determined whether to update the quality inspection result and whether to re-execute the steps of determining the cutting plan and cutting path corresponding to the target glass based on the quality inspection result, the target glass and the glass to be cut.
[0122] Thus, when the new quality inspection result is inconsistent with the quality inspection result, it indicates that a new bad area is generated when the glass to be cut is cut. At this time, the new quality inspection result is used as the quality inspection result, and the steps of determining the cutting scheme and cutting path corresponding to the target glass are performed according to the quality inspection result, the target glass and the glass to be cut, so as to ensure the quality of the final glass product and avoid the waste of the high-quality area. When the new quality inspection result is consistent with the quality inspection result, it indicates that no new bad area is generated during the cutting process. At this time, the step of cutting the glass to be cut according to the cutting scheme and cutting path can be performed.
[0123] The glass cutting control method provided in the embodiment of the present application performs quality inspection on the glass to be cut, obtains the quality inspection result of the glass to be cut, and determines the target glass according to the priority of each glass in the acquired glass order. Then, based on the quality inspection result, the target glass and the glass to be cut, the cutting scheme and cutting path of the target glass are determined, the glass to be cut is cut, and the above steps of determining the target glass according to the priority of each glass are repeated until the cutting stop condition is met. In this way, the cutting scheme and cutting path of the target glass are determined according to the quality inspection result, which can improve the utilization rate of the high-quality area, reduce the situation of defective products being mixed into qualified products, improve product yield, give priority to cutting the target glass with high priority, and improve production flexibility.
[0124] In some embodiments, this embodiment can display the quality inspection results of the glass to be cut, the glass order, the target glass, the cutting plan and cutting path corresponding to the target glass, and the current status of the glass to be cut, so that relevant personnel can quickly and intuitively understand the glass production process.
