Description

Technical Field

[0001] This application relates to the field of equipment control technology, and in particular to a control method and system for an adhesive coating machine. Background Technology

[0002] An adhesive coating machine is a device used to evenly coat adhesive onto the surface of a specific material. Based on different working mechanisms, it can be divided into hot melt adhesive coating machines, blade coating machines, roller coating machines, spray coating machines, dip coating machines, transfer coating machines, etc.

[0003] In the roller coating machine, the adhesive to be coated is first supplied to the coating roller through the adhesive supply system. Then, the unwinding and rewinding equipment are controlled to work simultaneously to move the material to be coated. At this time, the material can pass through the gap between the coating roller and the metering roller. The adhesive can be evenly applied to the surface of the material through the coating roller. Controlling the gap between the metering roller and the coating roller can effectively control the thickness of the adhesive coating.

[0004] In the aforementioned technologies, the coating roller will experience wear during use. When the coating roller is severely worn, the gap between the coating roller and the metering roller will increase compared to the set distance, resulting in a thicker layer of adhesive on the material surface. This not only increases the amount of adhesive wasted but also leads to poor quality of the resulting adhesive coating material, resulting in a poor overall coating effect and room for improvement. Summary of the Invention

[0005] In order to improve the overall working effect of glue coating operation, this application provides a glue coating machine control method and system.

[0006] In a first aspect, this application provides a control method for an adhesive coating machine, which adopts the following technical solution: A method for controlling an adhesive coating machine includes: Obtain the required coating thickness, the material surface image of the preset coating exit area, and the corresponding rotation angle range of the coating roller; The pixel height of each pixel in the material surface image is determined, and the difference between the pixel height and the preset reference height is calculated to determine the actual coating thickness. The difference between the required coating thickness and the actual coating thickness is calculated to determine the differential coating thickness. The permissible adjustment distance range is determined based on the differential coating thickness and the preset permissible difference range, and the standard adjustment distance range is determined by intersecting all permissible adjustment distance ranges. Select a unique actual adjustment distance from the standard adjustment distance range, match the actual adjustment distance with the rotation angle range, and control the movement of the metering roller according to the actual adjustment distance when the coating roller rotates to the rotation angle range.

[0007] Optionally, after the standard adjustment distance range is determined, the glue applicator control method may also include: The criterion for determining whether the distance range is empty is: If the standard adjustment distance range is not empty, then the actual adjustment distance is determined. If the standard adjustment distance range is empty, an abnormal prompt signal will be output, and any number of permissible adjustment distance ranges will be selected from all permissible adjustment distance ranges to construct a distance range set. The set of distance ranges in the distance range set that have an intersection and are not empty will be defined as the valid range set. The number of internal ranges is determined by counting the permitted adjustment distance ranges in each valid range set; The number of internal ranges with the largest value is determined according to the preset sorting rules, and the set of distance ranges corresponding to the number of internal ranges with the largest value is defined as the set of usage ranges. The standard adjustment distance range is determined according to the permitted adjustment distance range in the set of usage ranges.

[0008] Optionally, after the internal range quantity is determined, the glue applicator control method may further include: Determine if there exist at least two sets of distance ranges that have the same number of internal ranges and are the largest possible sets. If there are no at least two sets of distance ranges with the same number of internal ranges and the largest value, then the set of distance ranges corresponding to the largest number of internal ranges is defined as the set of ranges to be used. If there are at least two sets of distance ranges with the same number of internal ranges and the largest number of internal ranges, then the set of distance ranges corresponding to the largest number of internal ranges is defined as the candidate range set, the standard adjustment distance range determined by the candidate range set is defined as the reasonable distance range, and the permissible adjustment distance range outside the candidate range set is defined as the external distance range. A simulated adjustment distance is randomly generated within a reasonable distance range, and the numerical distance is determined based on the simulated adjustment distance and the external distance range. The reasonable parameters for simulation are determined by calculating the distance between all the values, and the reasonable parameter for simulation with the largest value is determined according to the sorting rules. The reasonable parameter for simulation with the largest value is defined as the binding reasonable parameter of the candidate range set. Based on the sorting rules, determine the reasonable binding parameter with the largest value, and determine the set of candidate ranges corresponding to the reasonable binding parameter as the set of usage ranges. Then, define the simulated adjustment distance corresponding to the reasonable binding parameter as the actual adjustment distance.

[0009] Optionally, after an abnormality warning signal is output and the actual adjustment distance is determined, the control method for the glue applicator further includes: The number of external ranges is determined by counting the external distance ranges. The proportion of internal quantity is determined by calculating the number of internal and external quantities. Determine whether the internal quantity ratio is greater than the preset demand quantity ratio; If the internal quantity ratio is greater than the demand quantity ratio, the glue coating machine will continue to operate; If the internal quantity ratio is not greater than the required quantity ratio, the glue coating machine will stop operating and output a wear warning signal.

[0010] Optionally, it also includes the step of selecting a unique actual adjustment distance within the standard adjustment distance range, which includes: According to the preset circumference rules, the standard adjustment distance range corresponding to each rotation angle range is combined to construct the circumference range combination; Within the perimeter range combination, a virtual adjustment distance is randomly selected from the corresponding standard adjustment distance ranges in sequence according to the order of priority. Each virtual adjustment distance is enclosed to form a data circle according to the rotation angle range. Within the data circle, the adjacent virtual adjustment distances are determined according to the preset direction of change. The difference between each adjacent virtual adjustment distance is calculated to determine the adjacent adjustment difference. The mean of adjacent adjustments is determined by averaging all adjacent adjustment differences. The minimum adjacent adjustment mean is determined according to the sorting rules, and the virtual adjustment distances corresponding to the minimum adjacent adjustment mean are determined as the actual adjustment distances corresponding to each rotation angle range.

[0011] Optionally, after the adjacent adjustment average is determined, the glue coating machine control method further includes: Determine if there exist at least two adjacent data loops with the same minimum adjusted mean; If there are no at least two adjacent adjustment mean values ​​that are the same and the smallest, then the actual adjustment distance corresponding to each rotation angle range is determined based on the data circle corresponding to the smallest adjacent adjustment mean value. If there are at least two adjacent data circles with the same and smallest adjustment mean, the adjustment difficulty coefficient corresponding to the adjacent adjustment difference is determined according to the preset difficulty matching relationship. The difficulty coefficient of the entire lap is determined by summing up all the adjustment difficulty coefficients. The sorting rules determine the minimum difficulty coefficient for the entire rotation operation, and the actual adjustment distance for each rotation angle range is determined based on the data circle corresponding to the minimum difficulty coefficient.

[0012] Secondly, this application provides a control system for an adhesive coating machine, which adopts the following technical solution: A control system for an adhesive coating machine includes: The acquisition module is used to acquire the required coating thickness, the material surface image of the preset coating exit area, and the corresponding rotation angle range of the coating roller. The processing module, connected to the acquisition module, is used for information storage and processing; The processing module determines the pixel height of each pixel in the material surface image, and calculates the difference between the pixel height and the preset reference height to determine the actual coating thickness. The processing module calculates the difference between the required coating thickness and the actual coating thickness to determine the difference coating thickness. The processing module determines the permissible adjustment distance range based on the difference coating thickness and the preset permissible difference range, and performs intersection processing on all permissible adjustment distance ranges to determine the standard adjustment distance range; The processing module selects a unique actual adjustment distance within the standard adjustment distance range and matches the actual adjustment distance with the rotation angle range. When the coating roller rotates to the rotation angle range, it controls the movement of the metering roller based on the actual adjustment distance.

[0013] Thirdly, this application provides a computer storage medium capable of storing corresponding programs, which improves the overall work effect of adhesive coating operations, and adopts the following technical solution: A computer-readable storage medium storing a computer program that can be loaded by a processor and executed any of the above-described glue coating machine control methods.

[0014] In summary, this application includes at least one of the following beneficial technical effects: When the glue coating machine is first used, the glue coating material obtained under the action of the coating roller can be tested to determine the actual glue coating situation. This allows us to know the wear of the coating roller and adjust the position between the coating roller and the metering roller so that the processed material meets the quality requirements and improves the overall operation effect of glue coating. When adjusting the distance between the coating roller and the metering roller, the distance to be adjusted in one revolution can be analyzed to make the metering roller easier to move. Attached Figure Description

[0015] Figure 1 This is a flowchart of the control method for an adhesive coating machine.

[0016] Figure 2 This is a flowchart of the control method for an adhesive coating machine. Detailed Implementation

[0017] To make the purpose, technical solution, and advantages of this application clearer, the following is combined with Figures 1-2 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0018] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0019] This application discloses a control method for an adhesive coating machine, referring to... Figure 1 The method and process for controlling an adhesive coating machine includes the following steps: Step S100: Obtain the required coating thickness, the material surface image of the preset coating exit area, and the corresponding rotation angle range of the coating roller.

[0020] The required coating thickness is the thickness of the adhesive needed for the material being coated. This thickness is manually entered by the operator. The coating exit area is the area where the material will move after being coated by the coating roller. The material surface image is the image of the coating exit area obtained by a camera installed directly above the coating exit area and facing downwards. The rotation angle range is the range of angles to which the coating roller will rotate when processing the material in the material surface image. This can be determined by installing an angle sensor on the rotation axis of the coating roller.

[0021] Step S101: Determine the pixel height of each pixel in the material surface image, and calculate the difference between the pixel height and the preset reference height to determine the actual coating thickness.

[0022] Pixel height is the distance between each pixel and the shooting device. Reference height is the height between the shooting device and the material surface when no glue is applied. Actual coating thickness is the actual thickness of the glue applied to the material surface, which is determined by subtracting the pixel height from the reference height.

[0023] Step S102: Calculate the difference between the required coating thickness and the actual coating thickness to determine the difference coating thickness.

[0024] The difference coating thickness is the value obtained by subtracting the required coating thickness from the actual coating thickness; this difference is a relative value.

[0025] Step S103: Determine the permissible adjustment distance range based on the difference coating thickness and the preset permissible difference range, and perform intersection processing on all permissible adjustment distance ranges to determine the standard adjustment distance range.

[0026] The permissible difference range is the range of glue thickness deviations allowed by the operator. The permissible adjustment distance range is the distance adjustment range within which the glue thickness still meets the requirements when the distance between the metering roller and the coating roller is adjusted. The lower endpoint of the permissible adjustment distance range can be determined by calculating the difference between the differential coating thickness and the lower endpoint of the permissible difference range. The upper endpoint of the permissible adjustment distance range can be determined by calculating the difference between the differential coating thickness and the upper endpoint of the permissible difference range. The standard adjustment distance range is the intersection range of all permissible adjustment distance ranges, which is the distance range that can satisfy the glue thickness adjustment of the corresponding position points under all pixels.

[0027] Step S104: Select a unique actual adjustment distance from the standard adjustment distance range, match the actual adjustment distance with the rotation angle range, and control the movement of the metering roller according to the actual adjustment distance when the coating roller rotates to the rotation angle range.

[0028] The actual adjustment distance is a value within the standard adjustment distance range. This value can be selected randomly or obtained through the methods in steps S500-S504. By determining the actual adjustment distance, it can be known that when the coating roller performs coating operations within the rotation angle range, the distance between the coating roller and the metering roller needs to be adjusted so that the glue thickness at each position point meets the requirements and the overall working effect of the glue coating operation is improved.

[0029] After the standard adjustment distance range is determined, the control method for the glue applicator also includes: Step S200: Determine whether the standard adjustment distance range is empty.

[0030] The purpose of this judgment is to determine whether the actual adjustment distance can be selected.

[0031] Step S2001: If the standard adjustment distance range is not empty, then determine the actual adjustment distance.

[0032] When the standard adjustment distance range is not empty, it means that the actual adjustment distance can be determined directly, and normal analysis and processing can be performed at this time.

[0033] Step S2002: If the standard adjustment distance range is empty, output an abnormal prompt signal, and select any number of permissible adjustment distance ranges from all permissible adjustment distance ranges to construct a distance range set, and define the set of distance ranges in the distance range set that have an intersection of permissible adjustment distance ranges and are not empty as the valid range set.

[0034] When the standard adjustment distance range is empty, it means that the actual adjustment distance cannot be directly determined. At this time, no distance value can meet the glue thickness requirements of each location point. Therefore, an abnormality prompt signal is output to identify the situation so that the staff can discover and deal with it in time. At the same time, the glue coating machine can continue to operate before the staff deals with it, so as to reduce the impact on material production efficiency. The distance range set is the set of randomly selected permissible adjustment distance ranges. The effective range set is defined to determine the cases where there is a common intersection, so as to distinguish different distance range sets and facilitate subsequent analysis.

[0035] Step S201: Count the permitted adjustment distance ranges in each valid range set to determine the number of internal ranges.

[0036] The number of internal ranges is the number of permissible adjustment distance ranges within a single defined set of valid ranges.

[0037] Step S202: Determine the number of internal ranges with the largest value according to the preset sorting rules, define the set of distance ranges corresponding to the number of internal ranges with the largest value as the set of usage ranges, and determine the standard adjustment distance range according to the permitted adjustment distance ranges in the set of usage ranges.

[0038] The sorting rules are methods set by the staff to sort numerical values, such as the bubble sort method. The sorting rules can determine the number of internal ranges with the largest values, that is, the number of positions that can meet the glue thickness requirements under the current situation. At this time, it is defined as the range set to distinguish different distance range sets. This allows the standard adjustment distance range to be determined by using the permissible adjustment distance range in the range set. This ensures that when the actual adjustment distance is determined and the glue coating machine is operated, there are more positions on the material surface that can meet the glue thickness requirements.

[0039] Once the internal range quantity is determined, the glue coating machine control method also includes: Step S300: Determine whether there exist at least two sets of distance ranges with the same number of internal ranges and the largest distance range.

[0040] The purpose of this judgment is to determine whether there are multiple sets of distance ranges that meet the requirement of the number of internal ranges, so as to determine the set of ranges to be used.

[0041] Step S3001: If there are no at least two sets of distance ranges with the same number of internal ranges and the largest number of internal ranges, then the set of distance ranges corresponding to the largest number of internal ranges is defined as the set of ranges to be used.

[0042] If there are no at least two sets of distance ranges with the same number of internal ranges and the largest possible range, it means that there is only one set of distance ranges that meets the requirements. In this case, it can be determined as the set of ranges to be used.

[0043] Step S3002: If there are at least two sets of distance ranges with the same number of internal ranges and the largest number of internal ranges, then the set of distance ranges corresponding to the largest number of internal ranges is defined as the candidate range set, the standard adjustment distance range determined by the candidate range set is defined as the reasonable distance range, and the permissible adjustment distance range outside the candidate range set is defined as the external distance range.

[0044] When there are at least two sets of distance ranges with the same number of internal ranges and the largest number of internal ranges, it indicates that there are multiple sets of distance ranges that can be used as sets of ranges. In this case, they are defined as candidate sets of ranges to distinguish between different sets of distance ranges. At the same time, reasonable distance ranges and external distance ranges are defined to identify different data, which facilitates subsequent analysis steps.

[0045] Step S301: Randomly generate a simulated adjustment distance within a reasonable distance range, and determine the numerical distance interval based on the simulated adjustment distance and the external distance range.

[0046] The simulated adjustment distance is a random number within a reasonable distance range. The numerical interval is the distance between the value corresponding to the simulated adjustment distance and the external distance range, which is the smallest distance among all the values ​​between the simulated adjustment distance and the external distance range.

[0047] Step S302: Calculate the reasonable parameters for simulation based on the distance between all the values, and determine the reasonable parameter for simulation with the largest value according to the sorting rules, and define the reasonable parameter for simulation with the largest value as the binding reasonable parameter of the candidate range set.

[0048] The simulated reasonable parameter is the parameter value that makes the overall glue thickness at the corresponding position points within each external distance range reasonable, based on the determined simulated adjustment distance. It is determined by averaging all the values ​​at intervals and taking the reciprocal of the average. The simulated reasonable parameter with the largest value can be determined by sorting rules. That is, the simulated adjustment distance corresponding to this value is the best in the reasonable distance range. At this time, the bound reasonable parameter is defined to identify the largest simulated reasonable parameter in different candidate range sets, which is convenient for subsequent analysis.

[0049] Step S303: Determine the reasonable binding parameter with the largest value according to the sorting rules, and determine the set of candidate ranges corresponding to the reasonable binding parameter as the set of usage ranges, and define the simulated adjustment distance corresponding to the reasonable binding parameter as the actual adjustment distance.

[0050] The sorting rules determine the optimal binding parameter with the largest value. This set of candidate ranges will have the best effect when used, and it can be selected as the set of ranges to be used. At the same time, the corresponding simulated adjustment distance is defined as the actual adjustment distance so that the distance between the coating roller and the metering roller after adjustment can enable better glue coating on the material surface.

[0051] After an abnormality warning signal is output and the actual adjustment distance is determined, the control method for the glue coating machine also includes: Step S400: Count the external distance range to determine the number of external ranges.

[0052] The number of external ranges, i.e. the number of locations that cannot meet the thickness requirements, can be determined by counting each of the defined external distance ranges.

[0053] Step S401: Calculate the proportion of internal quantity based on the quantity of internal scope and the quantity of external scope.

[0054] The internal quantity ratio is the percentage of locations that can meet the thickness requirements, and it is determined by the sum of the internal range quantity and the external range quantity.

[0055] Step S402: Determine whether the internal quantity ratio is greater than the preset demand quantity ratio.

[0056] The required quantity ratio is the minimum internal quantity ratio that the overall material must meet to ensure that it will not fail to meet the inspection standard due to substandard quality. The purpose of this judgment is to determine whether the material being processed can meet the quality inspection requirements.

[0057] Step S4021: If the internal quantity ratio is greater than the demand quantity ratio, then continue the operation of the glue coating machine.

[0058] When the internal quantity ratio is greater than the demand ratio, it means that although the materials currently being produced have defects, the quality can still pass inspection. In this case, the glue coating machine can be kept running normally while waiting for the staff to intervene and handle the situation.

[0059] Step S4022: If the internal quantity ratio is not greater than the required quantity ratio, control the glue coating machine to stop operating and output a wear warning signal.

[0060] When the internal quantity ratio is not greater than the demand ratio, it means that the material production requirements cannot be met at present. At this time, the glue coating machine is stopped to reduce the ineffective loss of materials. At the same time, a wear warning signal is output so that the staff can know the situation and intervene in time.

[0061] It also includes the step of selecting a unique actual adjustment distance within the standard adjustment distance range, which includes: Step S500: Based on the preset circumference rules, combine the standard adjustment distance ranges corresponding to each rotation angle range to construct a circumference range combination.

[0062] The circumference rule refers to the range of rotation angles that the coating roller can correspond to in one revolution. For example, if we analyze a rotation angle range of 30°, we can obtain 12 sets of standard adjustment distance range data. Combining these data can then yield the circumference range combination.

[0063] Step S501: In the combination of perimeter ranges, randomly select a virtual adjustment distance from the corresponding standard adjustment distance ranges in sequence.

[0064] The sequence refers to the order in which the coating rollers operate at each angle. A virtual adjustment distance is selected from each standard adjustment distance range to simulate the metering roller data that needs to be adjusted at each angle, which facilitates subsequent analysis.

[0065] Step S502: Form a data circle by enclosing each virtual adjustment distance according to the rotation angle range, and determine the adjacent virtual adjustment distances within the data circle according to the preset change direction, and calculate the difference between adjacent virtual adjustment distances to determine the adjacent adjustment difference.

[0066] The data circle is a circle containing numerical values ​​formed by enclosing each virtual adjustment distance according to the order of rotation angle range. The direction of change is the rotation and coating direction of the coating roller. By changing the direction of change and the data circle, the distance value that the metering roller needs to adjust in adjacent angle ranges can be known. That is, the value is obtained by calculating the difference between adjacent virtual adjustment distances in the direction of change. This value is the adjacent adjustment difference.

[0067] Step S503: Calculate the mean of adjacent adjustments based on all adjacent adjustment differences to determine the adjacent adjustment mean.

[0068] The average of adjacent adjustments is the average distance that the metering roller needs to be adjusted continuously when the coating roller completes one revolution. It is determined by averaging all adjacent adjustment differences.

[0069] Step S504: Determine the smallest adjacent adjustment mean according to the sorting rules, and determine the virtual adjustment distances corresponding to the smallest adjacent adjustment mean as the actual adjustment distances corresponding to each rotation angle range.

[0070] The sorting rules can be used to determine the average adjustment value of adjacent values ​​with the smallest value. At this point, the adjustment of the metering roller is most convenient under each virtual adjustment distance. Then, the determined virtual adjustment distances are set as the actual adjustment distances corresponding to each rotation angle range for the movement control of the metering roller.

[0071] After the average value of adjacent adjustments is determined, the control method for the glue coating machine also includes: Step S600: Determine whether there exist at least two adjacent data cycles with the same and smallest adjusted mean.

[0072] The purpose of the judgment is to determine whether there are multiple data circles that meet the requirements, so as to determine the actual adjustment distance under each unique range that meets the requirements.

[0073] Step S6001: If there are no at least two adjacent adjustment averages that are the same and the smallest, then determine the actual adjustment distance corresponding to each rotation angle range based on the data circle corresponding to the smallest adjacent adjustment average.

[0074] When there are no at least two adjacent data circles with the same and smallest adjustment mean, it indicates that there is a unique actual adjustment distance that facilitates the movement of the metering roller. In this case, the actual adjustment distance can be determined based on the data circles.

[0075] Step S6002: If there are at least two adjacent data circles with the same and smallest adjustment mean, then determine the adjustment difficulty coefficient corresponding to the adjacent adjustment difference according to the preset difficulty matching relationship.

[0076] When there are at least two adjacent data circles with the same and smallest average adjustment value, it indicates that there are multiple data circles that meet the requirements and further analysis is needed. The adjustment difficulty coefficient is the overall movement difficulty value of the metering roller from the position point required to move from one rotation angle range to the position point required to move to the adjacent rotation angle range. The larger the difference between adjacent adjustments, the greater the distance to be adjusted and the greater the difficulty of adjusting in a short period of time. The difficulty matching relationship between the two is determined in advance by the staff, and it is only necessary to ensure that the matching relationship is a positive proportional relationship.

[0077] Step S601: Sum all the adjustment difficulty coefficients to determine the overall operation difficulty coefficient.

[0078] The difficulty coefficient of the entire operation is the sum of the difficulty coefficients of all adjustments.

[0079] Step S602: Determine the minimum full-circle operation difficulty coefficient according to the sorting rules, and determine the actual adjustment distance corresponding to each rotation angle range based on the data circle corresponding to the minimum full-circle operation difficulty coefficient.

[0080] The sorting rules can be used to determine the difficulty coefficient of the entire operation with the smallest value. At this point, the overall operation of the metering roller under the corresponding data circle is the simplest. The actual adjustment distance can then be determined using this data circle.
