Description

Technical Field

[0001] The present invention relates to the technical field of glue coating control, and in particular to a glue coating control method, device, storage medium and two-component glue supply coating equipment. Background Art

[0002] In traditional industrial manufacturing processes, two-component adhesive coating equipment is widely used to accurately mix and apply polyurethane hot melt adhesives. Polyurethane hot melt adhesives are usually composed of two main components: isocyanate component and hydroxyl component. When these two components are mixed in the correct proportion, they can form a high-strength, high-durability bond.

[0003] In actual operation, such equipment needs to ensure the precise ratio of the two chemical components, because the accuracy of their ratio directly affects the curing performance and bonding quality of the glue. Traditional equipment usually uses a fixed ratio to mix the two components, but this method often ignores the impact of environmental factors (such as temperature and humidity) and material properties (such as changes in the activity of components) on the performance of the glue. Therefore, when these external or internal conditions change, the setting of a fixed ratio may not guarantee the best bonding performance and quality.

[0004] In addition, another disadvantage of traditional equipment is the lack of automatic adjustment function. When the ratio of isocyanate to hydroxyl needs to be adjusted according to different application requirements, the operator must adjust it manually, which is not only time-consuming but may also lead to inconsistent mixing ratios and affect the stability of product quality. The automatic adjustment function can adjust the ratio of chemical components according to the real-time monitored glue quality and environmental parameters, thereby ensuring that the adhesive is always used in the best condition and improving product quality and production efficiency.

[0065] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0068] Those skilled in the art will understand that Figure 1The structure shown in the figure does not constitute a limitation on the vehicle, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0071] Based on the above hardware structure, an embodiment of the gluing control method of the present invention is proposed.

[0072] Reference Figure 2 , Figure 2 The figure is a flow chart of the first embodiment of the gluing control method of the present invention, and the first embodiment of the gluing control method of the present invention is proposed.

[0073] In a first embodiment, the gluing control method comprises the following steps:

[0074] S10: Obtaining actual glue weights and preset glue dispensing parameters of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive in the two-component glue supply coating device.

[0075] It should be noted that the execution body of this embodiment may be a glue coating controller located in a two-component glue coating device, or other electronic devices that can achieve the above functions, and this embodiment does not limit this.

[0076] It should be noted that the two-component glue coating equipment is a device specially designed for mixing and applying two chemical components, which will react chemically after mixing to form the final adhesive or coating. Among them, the actual glue weight of the isocyanate component and the hydroxyl component refers to the weight of the isocyanate component or hydroxyl component actually used in the preparation process, which can affect the performance and quality of the polyurethane hot melt adhesive. The preset glue mixing parameters are the ideal ratio or parameters of the isocyanate component or hydroxyl component in the mixing, which are usually set according to the performance requirements and production process of the product.

[0077] Specifically, by using a weighing device or other precise measuring tool, the actual weight of the isocyanate component and the hydroxyl component in the polyurethane hot melt adhesive is obtained in real time. This weight refers to the amount of these two components actually used in the production process at a specific moment, usually expressed in weight units (such as grams or kilograms). The preset adhesive mixing parameters are set in advance to guide the ideal ratio or parameters of the two components during the mixing process. The preset adhesive mixing parameters can include information such as the ideal isocyanate to hydroxyl ratio, mixing rate, pressure, etc.

[0078] S20: Determine correction coefficients of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive based on the actual glue weight and preset glue preparation parameters.

[0079] It should be noted that the correction factor refers to the correction value calculated based on the difference between the actual measured weight of the isocyanate component and the hydroxyl component and the preset glue mixing parameters during the glue mixing process. This correction factor can be used to adjust the flow rate of each component in the mixing head to ensure that the final mixture ratio meets the design requirements. By calculating and adjusting the correction factor in real time, the ratio of the polyurethane hot melt adhesive can be kept stable and consistent during the production process, thereby ensuring the stability of product quality and performance. The accuracy and timeliness of the correction factor are crucial to ensure the accuracy of the glue ratio and the coating effect.

[0080] S30: When the correction coefficient is not within the preset allowable correction coefficient range, adjusting the actual glue weight of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive.

[0081] It should be noted that the preset allowable correction coefficient range refers to the allowable deviation range between the actual input amounts of the isocyanate component and the hydroxyl component set in the production process and the preset rubber formulation parameters.

[0082] Specifically, the actual weight of the isocyanate component and the hydroxyl component is continuously monitored and compared with the preset dispensing parameters to detect whether the correction factor deviates from the expected range. If the correction factor deviates from the preset range, the cause of the deviation needs to be identified. The reasons may include material supply problems, mixing equipment failure, changes in the production environment, etc. Take appropriate adjustment measures according to the cause of the deviation. For example, if the deviation is caused by material supply problems, the flow control parameters in the supply system can be adjusted; if the mixing equipment fails, the equipment needs to be repaired or parts replaced. After adjustment, recalibrate the mixing system to ensure that the input amounts of the isocyanate component and the hydroxyl component are as expected and the correction factor is restored to the preset range. Continue to monitor the actual input amounts and correction factors of the isocyanate component and the hydroxyl component to ensure that they remain stable during the production process, and take timely adjustment measures to deal with any deviations.

[0083] S40: Controlling the glue coating of the two-component glue supply coating device based on the actual glue weights of the adjusted isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive.

[0084] In the specific implementation, first, ensure that the coating equipment is in normal working condition, and calibrate the equipment to ensure that it can accurately control the amount of glue applied. According to the actual glue weight of the isocyanate component and the hydroxyl component of the adjusted polyurethane hot melt adhesive, adjust the parameters of the coating equipment, such as coating speed, pressure, etc., to ensure that the correct amount of glue is applied to the surface of the workpiece. After adjusting the coating parameters, monitor the coating effect in real time. This can include using sensors or visual systems to detect coating thickness, uniformity, and any poor coating conditions. Feedback control is performed based on the results of real-time monitoring. If it is found that the coating amount is insufficient or excessive, the coating parameters can be adjusted to correct the coating deviation in time to ensure that the quality and performance of the product meet the requirements. Continuously monitor the coating effect during the coating process and make adjustments as needed to keep the glue coating amount within the required range and ensure the consistency and stable quality of the product.

[0085] The present embodiment provides a method for controlling glue coating, the method comprising: obtaining the actual glue weight of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive in the two-component glue supply coating device and the preset glue dispensing parameters; determining the correction coefficient of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive based on the actual glue weight and the preset glue dispensing parameters; when the correction coefficient is not within the preset allowable correction coefficient range, adjusting the actual glue weight of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive; and controlling the glue coating of the two-component glue supply coating device based on the adjusted actual glue weight of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive, thereby automatically adjusting the actual feed amount of isocyanate and hydroxyl to correct the proportion deviation. The adjustment process is fully automated, reducing manual intervention and improving the accuracy and efficiency of the operation.

[0086] Reference Figure 3 , Figure 3 The figure is a flow chart of the second embodiment of the glue coating control method of the present invention. In the second embodiment, the glue coating control of the two-component glue supply coating device is performed based on the actual glue weight of the adjusted isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive, including:

[0087] S401: re-determining the correction coefficients of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive based on the actual glue weights of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive after adjustment.

[0088] S402: When the correction coefficient is within the preset allowable correction coefficient range, the two-component glue supply coating device is controlled to apply glue.

[0089] It should be noted that by recalculating the correction coefficient, it is possible to ensure that the ratio of the isocyanate component and the hydroxyl component remains stable during the production process. This helps to ensure that the performance and quality of the product remain consistent in batch production. The determination of the correction coefficient directly affects the parameter setting of the glue coating control. When the correction coefficient is within the preset range, it can ensure that the glue mixing parameters used in the coating process are accurate, thereby effectively controlling the amount of glue applied. And by accurately determining the correction coefficient, it is possible to avoid frequent parameter adjustments or other adjustment measures during the coating process. This helps to improve production efficiency and reduce problems such as production stagnation or increased scrap rate caused by adjustments. A stable correction coefficient can reduce variability in production, reduce scrap rate, and reduce unnecessary adjustments and reprocessing during production, thereby reducing production costs.

[0090] Further, in this embodiment, when the correction coefficient is within the preset allowable correction coefficient range, after the two-component glue supply coating device is controlled to apply glue, the method further includes:

[0091] S50: When the correction coefficient is not within the preset allowable correction coefficient range, the control status indicator light is displayed in a first status color;

[0092] S60: When the correction coefficient is within the preset allowable correction coefficient range, controlling the status indicator light to be displayed in a second status color.

[0093] It should be noted that the first status color can be a striking color, such as red or orange. This color usually indicates a warning or abnormal state, and is used to remind operators that there is a problem that needs to be solved. The second status color can be a color that indicates a normal state or a good state, such as green or blue. This color usually indicates that the system is in a normal operating state and there is no abnormality or problem that needs to be solved.

[0094] Specifically, when the correction coefficient is not within the preset allowable correction coefficient range, the function of controlling the status indicator to display in the first state color is to remind the operator that there is a problem and warn him that he needs to take action to adjust the correction coefficient so that it is within the preset range. When the correction coefficient is within the preset allowable correction coefficient range, the function of controlling the status indicator to display in the second state color is to indicate that the production process is in a normal state.

[0095] Further, in this embodiment, the preset glue dispensing parameters include the theoretical glue output of the isocyanate component, the theoretical glue output of the hydroxyl component, the preset glue supply speed, the preset glue dispensing measurement time, the preset value of the isocyanate component distribution ratio and the preset value of the hydroxyl component distribution ratio;

[0096] Accordingly, the correction coefficients of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive are determined based on the actual glue weight and the preset glue mixing parameters, including:

[0097] Determining the theoretical glue weight of the isocyanate component based on the preset glue preparation parameters by using a preset theoretical glue weight calculation formula of the isocyanate component;

[0098] Determining the correction factor of the isocyanate component by a preset isocyanate component correction factor calculation formula based on the theoretical glue weight of the isocyanate component and the actual glue weight;

[0099] Wherein, the preset isocyanate component theoretical glue weight calculation formula is:

[0100]

[0101] Where W -NCO理 is the theoretical glue output of the isocyanate component, S is the preset glue supply speed, t is the preset glue preparation measurement time, B -NCO Preset value for isocyanate component ratio, B -OH Preset values ​​for the hydroxyl group ratio;

[0102] Wherein, the preset isocyanate component correction coefficient calculation formula is:

[0103]

[0104] Where, X -NCO修 is the correction factor of the isocyanate component, W -NCO实 is the actual glue weight of the isocyanate component, W -NCO理 is the theoretical glue weight of the isocyanate component;

[0105] Similarly, the theoretical glue weight of the hydroxyl component is determined based on the preset glue preparation parameters by using a preset hydroxyl component theoretical glue weight calculation formula;

[0106] Determining a correction factor of the hydroxyl component by a preset hydroxyl component correction factor calculation formula based on the theoretical glue weight of the hydroxyl component and the actual glue weight;

[0107] Wherein, the preset hydroxyl component theoretical glue weight calculation formula is:

[0108]

[0109] Where W -OH理 is the theoretical glue output of the hydroxyl component, S is the preset glue supply speed, t is the preset glue preparation measurement time, B -NCO Preset value for isocyanate component ratio, B -OH Preset values ​​for the hydroxyl group ratio;

[0110] Wherein, the preset hydroxyl component correction coefficient calculation formula is:

[0111]

[0112] Where, X -OH修 is the correction factor of the hydroxyl component, W -OH实 is the actual glue weight of the hydroxyl component, W -OH理 is the theoretical glue weight of the hydroxyl component.

[0113] It should be noted that the theoretical glue output of the isocyanate component or the hydroxyl component refers to the theoretical glue output calculated according to the formula of the isocyanate component or the hydroxyl component; the preset glue supply speed refers to the glue supply speed of the isocyanate component and the hydroxyl component set during the coating process; the preset glue preparation measurement time refers to the time set during the glue preparation process to ensure that the isocyanate component and the hydroxyl component are mixed in time according to the preset ratio; the preset value of the isocyanate component ratio refers to the ratio of the isocyanate component to the hydroxyl component determined in the formula; the preset value of the hydroxyl component ratio refers to the ratio of the hydroxyl component to the isocyanate component determined in the formula. The correction coefficient of the isocyanate component or the hydroxyl component is a coefficient used to adjust the density parameter of the isocyanate component or the hydroxyl component to correct the deviation between the actual glue density and the theoretical value; the actual glue weight of the isocyanate component or the hydroxyl component refers to the weight of the isocyanate component or the hydroxyl component used in the actual coating process; and the theoretical glue weight of the isocyanate component or the hydroxyl component is the theoretical glue weight calculated according to the formula of the isocyanate component or the hydroxyl component, which is determined based on the glue component ratio.

[0114] It should be understood that by calculating the correction coefficient of the isocyanate component or the hydroxyl component, it can be ensured that the amount of each component used in the actual rubber mixing process is consistent with the preset rubber mixing parameters, thereby ensuring accurate mixing ratios and avoiding product quality problems caused by ratio deviations.

[0115] Reference Figure 4 , Figure 4 The flowchart of the third embodiment of the glue coating control method of the present invention is shown in the figure. In the third embodiment, the glue coating control of the two-component glue supply coating device is performed based on the actual glue weight of the adjusted isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive, including:

[0116] S401': determining a first release time of the isocyanate component and a second release time of the hydroxyl component based on the actual glue weights of the isocyanate component and the hydroxyl component of the adjusted polyurethane hot melt adhesive, wherein the first release time is less than the second release time;

[0117] S402': Controlling the two-component glue supply coating device based on the first release time and the second release time.

[0118] It should be noted that when the isocyanate component pump and the hydroxyl component pump in the two-component glue coating equipment are started at the same time, the static mixing tube will be filled with the hydroxyl component first, resulting in a lack of isocyanate component in the initial glue discharge portion. Such uneven ratios will result in partial inability to fully cure the composite film after coating, posing a serious hidden danger.

[0119] In order to solve the above problems, the release time of the isocyanate component and the hydroxyl component can be determined according to the actual glue weight of the isocyanate component and the hydroxyl component of the adjusted polyurethane hot melt adhesive. Generally, it is necessary to ensure that the release time of the isocyanate component is earlier than the release time of the hydroxyl component so as to ensure the full reaction of the isocyanate component and the hydroxyl component during the mixing process.

[0120] Specifically, the first release time of the isocyanate component and the second release time of the hydroxyl component can be determined by experiments or simulations. Once the two release times are determined, the glue coating control can be performed on the two-component glue supply coating equipment. Such control can ensure the uniform mixing of the isocyanate component and the hydroxyl component in the mixture, thereby avoiding the curing problem caused by uneven ratio and ensuring the quality and performance of the film after coating.

[0121] The first release time refers to the time when the isocyanate component starts to be supplied from the pump to the mixer, and the second release time refers to the time when the hydroxyl component starts to be supplied from the pump to the mixer.

[0122] Furthermore, in this embodiment, after the first release time is less than the second release time, the method further includes:

[0123] Obtaining a preset glue supply speed of the two-component glue coating device;

[0124] Determine the difference between the first release time and the second release time by a delay time calculation formula based on the preset glue supply speed, the actual glue weight of the isocyanate component and the hydroxyl component;

[0125] Correspondingly, the controlling of the two-component glue supply coating device based on the first release time and the second release time includes:

[0126] Controlling the glue coating of the two-component glue supply coating device based on the difference between the first release time and the second release time;

[0127] Wherein, the delay time calculation formula is:

[0128]

[0129] Where, t is the delay time, S is the preset glue supply speed, W -OH实 is the actual glue weight of the hydroxyl component, W -NCO实 It is the actual glue weight of the isocyanate component.

[0130] It should be noted that in order to ensure that the release time difference between the adjusted isocyanate component and the hydroxyl component can be accurately controlled during the glue supply process to achieve uniform mixing and timely reaction of the mixture. By presetting the glue supply speed and delay time calculation formula, the difference between the first release time and the second release time can be determined so that timely control and adjustment can be made during the coating process. This can effectively avoid the curing problem caused by uneven ratio and improve the quality and performance of the coated film.

[0131] Among them, the delay time refers to the difference between the first release time and the second release time, the actual glue weight of the isocyanate component or the hydroxyl component refers to the weight of the isocyanate component or the hydroxyl component used in the actual coating process, and the preset glue supply speed refers to the glue supply speed pre-set in the two-component glue supply coating equipment, that is, the glue supply speed of the isocyanate component and the hydroxyl component in the mixer.

[0132] Further, in this embodiment, after determining the correction coefficients of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive based on the actual glue weight and the preset glue preparation parameters, it also includes:

[0133] Obtaining original density parameters of the isocyanate component and the hydroxyl component of the polyurethane hot melt adhesive;

[0134] Determining a new density parameter based on the original density parameter and the correction coefficient;

[0135] The new density parameter is sent to the display screen of the two-component glue supply and coating device for display.

[0136] It should be noted that the original density parameter refers to the density parameter determined by the composition ratio of the isocyanate component and the hydroxyl component of the glue without considering the correction coefficient. The new density parameter refers to the density parameter adjusted by the correction coefficient. The correction coefficient is determined based on the actual glue weight and the preset glue mixing parameters, and is used to correct the deviation of the original density parameter to make it more in line with the actual situation. The new density parameter is displayed by sending the corrected parameter to the display screen of the two-component glue coating equipment, providing real-time information feedback to the operator. Such density parameters can more accurately reflect the actual density of the glue, help operators adjust the operating parameters of the equipment, and ensure that the quality and effect of the coated glue meet the expected level.
