Description

Technical Field

[0001] This invention proposes a method and system for controlling the production of adhesive products, belonging to the field of intelligent control of adhesive tape production. Background Technology

[0002] Traditional continuous production lines for adhesive products mostly employ uniform temperature zone parameters and constant conveyor speeds. Process control relies on pre-defined standard procedures, making it impossible to provide precise and dynamic compensation for the actual curing state of each material segment in different temperature zones. If the curing effect of a preceding temperature zone is abnormal, subsequent temperature zones cannot automatically identify and remedy this, easily leading to insufficient or excessive curing, affecting product consistency and yield. Most lines use uniform process parameter settings (such as constant speed and temperature), with macro-adjustments only made at the initial stage of production or during batch changes. For problems such as insufficient curing or temperature fluctuations in individual material segments during actual production, there is a lack of precise segmented data traceability and personalized compensation mechanisms. If a segment of material fails to meet curing requirements, targeted remedies are often impossible, resulting in a lower overall yield. Existing control methods rely heavily on fixed sensors and limited sampling, making it difficult to capture key information such as the actual curing degree and temperature history of each material segment in a timely and comprehensive manner. Even when anomalies are detected, there is a lack of real-time, automated feedback and adjustment capabilities, preventing dynamic optimization of process parameters (such as speed and residence time). This makes the production process sensitive to environmental interference and batch differences, easily affecting product consistency. Summary of the Invention

[0003] Therefore, the purpose of this invention is to overcome the problem in the prior art that once the curing effect of the preceding temperature zone is abnormal, the subsequent temperature zone cannot be automatically identified and remedied, which easily leads to insufficient curing degree of the material and affects the consistency and pass rate of the product. The invention provides a production control method for adhesive products. By implementing a segmented data traceability and personalized data compensation mechanism for adhesive product materials, targeted remediation can be achieved for adhesive product materials that have not met the curing requirements, thereby improving the pass rate of adhesive product products.

[0004] To solve the above-mentioned technical problems, the present invention provides a method for controlling the production of adhesive products, the method comprising: The unit segment code of the adhesive product material, the time of entering the first temperature zone, the time of leaving the first temperature zone and its temperature distribution data in the first temperature zone are correlated in real time to form a first correlation data group, and a spatiotemporal mapping table is established based on multiple correlation data groups. Based on the spatiotemporal mapping table, obtain the correlation data of the first unit segment of the adhesive product material in the first temperature zone, and adjust the curing time of the first unit segment of the adhesive product material in the second temperature zone according to the correlation data of the first unit segment in the first temperature zone. The moving speed of the adhesive product material in the curing oven is adjusted based on the curing time of the first unit segment of the adhesive product material in the second temperature zone; wherein, the moving speed is adjusted when there is a preset deceleration distance from the second temperature zone, and the production of the adhesive product is controlled according to the adjusted moving speed of the adhesive product; along the moving direction of the adhesive product, the second temperature zone is the next temperature zone after the first temperature zone.

[0005] Furthermore, the unit segment codes of the adhesive product material, the time of entering the first temperature zone, the time of leaving the first temperature zone, and their temperature distribution data within the first temperature zone are correlated in real time to form a first correlated data group. A spatiotemporal mapping table is then established based on multiple correlated data groups, including: Along the direction of movement of the adhesive product material in the curing oven, the adhesive product material is divided into multiple unit segments, and each unit segment is coded to form the unit segment code; The time when the starting end of the first unit segment of the adhesive product material enters the first temperature zone is recorded as the time of entering the first temperature zone, and the time when its ending end leaves the first temperature zone is recorded as the time of leaving the first temperature zone; the temperature distribution data of the first unit segment of the adhesive product material in the first temperature zone is monitored by sensors installed inside the curing oven; The coding of the first unit segment of the adhesive product material, the time when the first unit segment enters the first temperature zone, the time when the first unit segment leaves the first temperature zone, and its temperature distribution data within the first temperature zone are correlated in real time to form the first correlated data group; The spatiotemporal mapping table is established based on the associated data set of all unit segments of the adhesive product material.

[0006] Further, based on the spatiotemporal mapping table, the association data of the first unit segment of the adhesive product material in the first temperature zone is obtained, and the curing time of the first unit segment of the adhesive product material in the second temperature zone is adjusted according to the association data of the first unit segment in the first temperature zone, including: Before the first unit segment of the adhesive product material enters the second temperature zone, the associated data group of the first unit segment of the adhesive product material in the first temperature zone is extracted from the spatiotemporal mapping table according to the unit segment code of the adhesive product material. The actual degree of curing of the first unit segment of the adhesive product material when it leaves the first temperature zone is obtained based on the temperature distribution data in the associated data group of the first temperature zone. The curing degree difference of the first unit segment of the adhesive product material in the first temperature zone is obtained based on the actual curing degree and the target curing degree; if the curing degree difference of the first unit segment of the adhesive product material in the first temperature zone is less than or equal to 0, then the first unit segment of the adhesive product material meets the standard and passes through the reference speed when entering the second temperature zone; If the curing degree difference of the first unit segment of the adhesive product material in the first temperature zone is greater than 0, then the curing compensation of the first unit segment of the adhesive product material in the second temperature zone is performed based on the curing degree difference in the first temperature zone.

[0007] Further, if the degree of curing difference of the first unit segment of the adhesive product material within the first temperature zone is greater than 0, then based on the degree of curing difference within the first temperature zone, the first unit segment of the adhesive product material is cured in the second temperature zone, including: S1. Obtain the curing efficiency of the first unit segment of the adhesive product material in the second temperature zone; S2. Calculate the compensation time of the first unit segment of the adhesive product material in the second temperature zone based on the curing degree difference of the first unit segment in the first temperature zone. ,in, This indicates the compensation time for a single unit segment of the adhesive product material in the second temperature zone.

This indicates the reference curing time of the adhesive product material unit segment in the second temperature zone. ,in, Indicates the length of the second temperature zone. This indicates the speed of the first unit segment of the adhesive material after adjustment in the second temperature zone; S4. When the first unit segment of the adhesive product material leaves the second temperature zone, the actual degree of curing of the adhesive product material unit segment is obtained. If the actual degree of curing of the adhesive product material unit segment in the second temperature zone is greater than or equal to the target degree of curing of the adhesive product material unit segment in the second temperature zone, it indicates that the standard has been met and the compensation is completed. S5. If the actual degree of curing of the first unit segment of the adhesive product material in the second temperature zone is less than the target degree of curing of the first unit segment of the adhesive product material in the second temperature zone, then calculate the second difference and transfer it to the third temperature zone, repeating steps S1-S4. S6. If the number of compensations for the first unit segment of the adhesive product material exceeds the preset number, it will be marked as an abnormal segment, and subsequent temperature zones will no longer be compensated, and a manual inspection will be triggered.

[0008] Further, the moving speed of the adhesive product material in the curing oven is adjusted based on the curing time of the first unit segment of the adhesive product material in the second temperature zone; wherein, the moving speed is adjusted starting when there is a preset deceleration distance from the second temperature zone, and the production of the adhesive product is controlled according to the adjusted moving speed of the adhesive product, including: Before the first unit segment of the adhesive product material enters the second temperature zone, deceleration is triggered, and the deceleration time is determined by the deceleration time model. Based on the deceleration time, the deceleration distance is determined using a deceleration distance model; The deceleration time model is as follows: ,in, This indicates the reference speed of the first unit segment of the adhesive material as it passes through the second temperature zone.

[0009] This invention proposes a production control system for adhesive products, the system comprising: The association module is used to associate the unit segment code, entry time into the first temperature zone, and exit time of the first temperature zone of the adhesive product material with its temperature distribution data in the first temperature zone in real time to form a first association data group, and to establish a spatiotemporal mapping table based on multiple association data groups. The curing time acquisition module acquires the correlation data of the first unit segment of the adhesive product material in the first temperature zone based on the spatiotemporal mapping table, and adjusts the curing time of the first unit segment of the adhesive product material in the second temperature zone according to the correlation data of the first unit segment in the first temperature zone. The speed adjustment module is used to adjust the moving speed of the adhesive product material in the curing oven based on the curing time of the first unit segment of the adhesive product material in the second temperature zone; wherein, the moving speed is adjusted when there is a preset deceleration distance from the second temperature zone, and the production of the adhesive product is controlled according to the adjusted moving speed of the adhesive product; along the moving direction of the adhesive product, the second temperature zone is the next temperature zone after the first temperature zone.

The compliance determination unit is used to obtain the degree of curing difference of the first unit segment of the adhesive product material in the first temperature zone based on the actual degree of curing and the target degree of curing; if the degree of curing difference of the first unit segment of the adhesive product material in the first temperature zone is less than or equal to 0, then the first unit segment of the adhesive product material meets the standard and passes through the second temperature zone at the reference speed. A curing compensation unit is used to perform curing compensation on the first unit segment of the adhesive product material in a second temperature zone based on the curing degree difference in the first temperature zone if the curing degree difference in the first temperature zone is greater than 0.

[0014] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial effects: The adhesive product production control method and system of the present invention, through the segmented data traceability and data compensation mechanism of adhesive product materials, realizes targeted remediation of adhesive product materials that have not met the curing requirements, thereby improving the product qualification rate of adhesive products.

[0015] Firstly, by installing an encoder at the entrance of the curing oven and linking it with the material conveyor belt, the absolute position of each unit segment of the adhesive product material is accurately tracked, forming a complete "spatiotemporal mapping table". This ensures that the process experience of each segment of material (temperature curve, curing progress, etc.) has a complete data link, which facilitates subsequent process compensation and quality traceability, and improves intelligent control capabilities. Based on the correlation data of the first unit segment in the first temperature zone, the curing time in the second temperature zone is adjusted. If abnormal situations such as unsatisfactory heating effect occur in the first temperature zone, compensation can be made by extending the curing time in the second temperature zone, which can effectively eliminate or reduce internal quality fluctuations of the product and improve the consistency and pass rate of the final product. Adjusting the speed in advance according to the curing time is to prevent sudden speed changes from causing tension impact, wrinkling, or deviation of the adhesive products, and to ensure smooth speed changes and stable material operation.

[0016] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings, wherein... Figure 1 This is a flowchart of the adhesive product production control method in a preferred embodiment of the present invention; Figure 2 This is a flowchart illustrating the process of determining whether to perform curing compensation in a preferred embodiment of the present invention; Figure 3 This is a structural block diagram of the adhesive product production control system in a preferred embodiment of the present invention. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0018] Example 1: Refer to Figure 1 As shown in the embodiment of the present invention, a method for controlling the production of adhesive products is disclosed. The adhesive products are cured in a curing oven, which is provided with multiple temperature zones. The method includes: The unit segment code of the adhesive product material, the time of entering the first temperature zone, the time of leaving the first temperature zone and its temperature distribution data in the first temperature zone are correlated in real time to form a first correlation data group, and a spatiotemporal mapping table is established based on multiple correlation data groups. Based on the spatiotemporal mapping table, obtain the correlation data of the first unit segment of the adhesive product material in the first temperature zone, and adjust the curing time of the first unit segment of the adhesive product material in the second temperature zone according to the correlation data of the first unit segment in the first temperature zone. The moving speed of the adhesive product material in the curing oven is adjusted based on the curing time of the first unit segment of the adhesive product material in the second temperature zone; wherein, the moving speed is adjusted when there is a preset deceleration distance from the second temperature zone, and the production of the adhesive product is controlled according to the adjusted moving speed of the adhesive product; along the moving direction of the adhesive product, the second temperature zone is the next temperature zone after the first temperature zone.

[0019] In specific application scenarios, on large-scale continuous production lines for adhesive products, the curing performance of the adhesive products is affected by curing process parameters. The continuously moving adhesive product material is divided into several unit segments, each assigned a unique unit segment code. The time when the first unit segment enters and leaves the first temperature zone is collected in real time. Simultaneously, as the first unit segment passes through the first temperature zone, temperature sensors capture its temperature distribution data. This temperature distribution data, after automatic collection, is correlated in real time with the unit segment code and time tag to form a first correlated data group. Multiple correlated data groups are continuously accumulated to dynamically establish a spatiotemporal mapping table for the adhesive product, comprehensively reflecting the real-time process status characteristics of each unit segment in each temperature zone of the curing oven. Based on the constructed spatiotemporal mapping table, the temperature distribution data in the correlated data of the first unit segment of the adhesive product material is extracted to analyze its curing effect. If the first unit segment of the adhesive product material... If the curing degree in the first temperature zone does not reach the expected target, the curing time of the first unit segment of the adhesive product material in the second temperature zone is automatically adjusted. The curing time in the second temperature zone is appropriately extended to compensate for the process fluctuations in the previous zone, ensuring that the curing reaction is sufficient and uniform. Based on the adjustment result of the curing time of the first unit segment of the adhesive product material in the second temperature zone, the moving speed of the adhesive product material in the curing oven that needs to be adjusted is calculated. To avoid wrinkling of the adhesive product material caused by sudden changes in moving speed, a preset deceleration distance is designed: that is, before the adhesive product material approaches the entrance of the second temperature zone, the moving speed of the strip is gradually adjusted as needed at a certain distance in advance, so that the adhesive product material smoothly transitions to the new process cycle. Here, the first temperature zone is only a name for convenient description of the process sequence and is not limited to a specific physical area. It can be understood that the naming of the first unit segment of the adhesive product material and the first temperature zone in this invention is only for convenient expression. This technical solution can be applied to each unit segment of the adhesive product material when passing through each temperature zone.

[0020] In one embodiment of the present invention, the unit segment code, entry time into the first temperature zone, and exit time of the first temperature zone of the adhesive product material are correlated in real time with its temperature distribution data within the first temperature zone to form a first correlation data group. A spatiotemporal mapping table is then established based on multiple correlation data groups, including: Along the direction of movement of the adhesive product material in the curing oven, the adhesive product material is divided into multiple unit segments, and each unit segment is coded to form the unit segment code; The time when the starting end of the first unit segment of the adhesive product material enters the first temperature zone is recorded as the time of entering the first temperature zone, and the time when its ending end leaves the first temperature zone is recorded as the time of leaving the first temperature zone; the temperature distribution data of the first unit segment of the adhesive product material in the first temperature zone is monitored by sensors installed inside the curing oven; The coding of the first unit segment of the adhesive product material, the time when the first unit segment enters the first temperature zone, the time when the first unit segment leaves the first temperature zone, and its temperature distribution data within the first temperature zone are correlated in real time to form the first correlated data group; The spatiotemporal mapping table is established based on the associated data set of all unit segments of the adhesive product material.

[0021] In specific application scenarios, a length counter is set at the position before the adhesive product material enters the curing oven, and a starting reference point is set. Once the starting end of the first unit segment of the adhesive product material passes this point, the starting point of the code for the first unit segment of the adhesive product material is initialized. The length counter tracks the position of the adhesive product material in real time, so that each segment of the adhesive product material corresponds synchronously with its unique unit segment code. Along the direction of movement of the adhesive product material in the curing oven, the continuously moving adhesive product strip is divided into multiple unit segments at equal intervals, and a unique code is assigned to each unit segment. The code of each unit segment can contain information such as batch and production time period. Through the spatiotemporal mapping table, the process history of each unit segment of the adhesive product material can be accurately traced and dynamically analyzed in real time, providing solid data support for subsequent intelligent manufacturing links such as curing time optimization, movement speed adjustment, and quality traceability.

[0022] One embodiment of the present invention, referred to Figure 2 As shown, the process involves obtaining the correlation data of the first unit segment of the adhesive product material in the first temperature zone based on the spatiotemporal mapping table, and adjusting the curing time of the first unit segment of the adhesive product material in the second temperature zone according to the correlation data of the first unit segment in the first temperature zone, including: Before the first unit segment of the adhesive product material enters the second temperature zone, the associated data group of the first unit segment of the adhesive product material in the first temperature zone is extracted from the spatiotemporal mapping table according to the unit segment code of the adhesive product material. The actual degree of curing of the first unit segment of the adhesive product material when it leaves the first temperature zone is obtained based on the temperature distribution data in the associated data group of the first temperature zone. The curing degree difference of the first unit segment of the adhesive product material in the first temperature zone is obtained based on the actual curing degree and the target curing degree; if the curing degree difference of the first unit segment of the adhesive product material in the first temperature zone is less than or equal to 0, then the first unit segment of the adhesive product material meets the standard and passes through the reference speed when entering the second temperature zone; If the curing degree difference of the first unit segment of the adhesive product material in the first temperature zone is greater than 0, then the curing compensation of the first unit segment of the adhesive product material in the second temperature zone is performed based on the curing degree difference in the first temperature zone.

[0023] In one embodiment of the present invention, if the degree of curing difference of the first unit segment of the adhesive product material in a first temperature zone is greater than 0, then the first unit segment of the adhesive product material is cured in a second temperature zone based on the degree of curing difference in the first temperature zone, including: S1. Obtain the curing efficiency of the first unit segment of the adhesive product material in the second temperature zone; S2. Calculate the compensation time of the first unit segment of the adhesive product material in the second temperature zone based on the curing degree difference of the first unit segment in the first temperature zone. ,in, This indicates the compensation time for a single unit segment of the adhesive product material in the second temperature zone. This indicates the degree of curing difference of a single segment of adhesive material in the first temperature zone. This indicates the curing efficiency in the second temperature zone; S3. Obtain the curing time and adjusted speed of the first unit segment of the adhesive product material in the second temperature zone based on the compensation time of the first unit segment in the second temperature zone: ,in, This indicates the curing time of the adhesive product material unit segment in the second temperature zone. This indicates the reference curing time of the adhesive product material unit segment in the second temperature zone. ,in, Indicates the length of the second temperature zone. This indicates the speed of the first unit segment of the adhesive material after adjustment in the second temperature zone; S4. When the first unit segment of the adhesive product material leaves the second temperature zone, the actual degree of curing of the adhesive product material unit segment is obtained. If the actual degree of curing of the adhesive product material unit segment in the second temperature zone is greater than or equal to the target degree of curing of the adhesive product material unit segment in the second temperature zone, it indicates that the standard has been met and the compensation is completed. S5. If the actual degree of curing of the first unit segment of the adhesive product material in the second temperature zone is less than the target degree of curing of the first unit segment of the adhesive product material in the second temperature zone, then calculate the second difference and transfer it to the third temperature zone, repeating steps S1-S4. S6. If the number of compensations for the first unit segment of the adhesive product material exceeds the preset number, it will be marked as an abnormal segment, and subsequent temperature zones will no longer be compensated, and a manual inspection will be triggered.

[0024] In specific application scenarios, the curing efficiency of the second temperature zone is monitored online. Defined as "the increase in curing degree per unit time", select the nearest normal adhesive product material unit segment (meeting the standard in the second temperature zone and passing through the third temperature zone at the reference speed), and record its curing degree at the entrance of the second temperature zone. Export curing degree The real-time curing efficiency of the second temperature zone is: , This indicates the basic curing time of the adhesive product material unit segment in the second temperature zone. Next, based on the curing degree difference in the first temperature zone, the additional compensation time required for the first unit segment in the second temperature zone is calculated to ensure the curing degree catches up with the preset target. Then, the baseline curing time and compensation time of the first unit segment in the second temperature zone are superimposed to obtain its total curing time in the second temperature zone. Combined with the actual physical length of the second temperature zone, the passage speed of the unit segment is automatically adjusted so that its residence time in the second temperature zone exactly meets the curing compensation requirements. After the first unit segment leaves the second temperature zone, its actual curing degree is collected again. If... If the actual curing degree has reached or exceeded the target setting, it indicates that the curing compensation has been successful and normal production continues. If it still does not meet the target, the curing difference of the unit segment is automatically transferred to the next temperature zone, and the compensation steps are repeated in subsequent temperature zones. The curing degree is progressively improved through multiple temperature zones, gradually approaching the process target. To prevent excessive compensation under extreme conditions (such as abnormal raw materials, equipment failure, etc.), there is an upper limit to the number of compensations. If a unit segment still fails to meet the target after multiple temperature zone compensations and the number of compensations exceeds the preset threshold, it is automatically marked as an "abnormal segment" and will no longer participate in subsequent compensations. Manual intervention and quality inspection are triggered to ensure the controllability and traceability of the overall product quality.

[0025] In one embodiment of the present invention, the moving speed of the adhesive product material in the curing oven is adjusted based on the curing time of the first unit segment of the adhesive product material in the second temperature zone; wherein the moving speed is adjusted starting when there is a preset deceleration distance from the second temperature zone, and the production of the adhesive product is controlled according to the adjusted moving speed of the adhesive product, including: Before the first unit segment of the adhesive product material enters the second temperature zone, deceleration is triggered, and the deceleration time is determined by the deceleration time model. Based on the deceleration time, the deceleration distance is determined using a deceleration distance model; The deceleration time model is as follows: ,in, This indicates the reference speed of the first unit segment of the adhesive material as it passes through the second temperature zone. Indicates the deceleration time. This indicates the speed of the first unit segment of the adhesive material after adjustment in the second temperature zone. This indicates the maximum allowable acceleration of a single segment of the adhesive material. The deceleration distance model is as follows: ,in, Indicates the deceleration distance.

[0026] In specific application scenarios, when adhesive materials accelerate, according to Newton's second law F=ma, acceleration generates additional tension (force). For flexible materials like adhesives, the maximum allowable acceleration is essentially the maximum acceleration corresponding to the maximum tension the adhesive material can withstand, i.e., avoiding tension exceeding the material's limits and causing breakage or permanent deformation. When the first unit segment of the adhesive material is about to enter the second temperature zone, and it is detected that the curing time of this unit segment needs to be extended within the second temperature zone, the deceleration control process is automatically triggered. Based on the current process status and target curing parameters of this segment, combined with the set reference speed and the adjusted moving speed of the adhesive, the deceleration time model is used to calculate in real time the deceleration time required for the first unit segment of the adhesive material to decelerate from the reference speed to the target speed. Then, based on the calculated deceleration... The system calculates the required deceleration distance before entering the second temperature zone by using a deceleration distance model. This model ensures a smooth and precise deceleration process, preventing mechanical stress damage and wrinkling of the adhesive material. It effectively reduces the risk of surface defects, misalignment, and breakage caused by sudden speed changes, while providing sufficient dwell time for subsequent curing compensation in the temperature zone. The system automatically completes speed adjustment, distance monitoring, and acceleration / deceleration without manual intervention, significantly improving the automation and intelligence of the production process. The pre-set deceleration distance ensures that each material segment enters the critical temperature zone with the optimal trajectory, achieving "timely and accurate" compensation, greatly improving process consistency and finished product qualification rate.

[0027] Example 2: An embodiment of the present invention, a production control system for adhesive products, referring to... Figure 3 As shown, the system includes: The association module is used to associate the unit segment code, entry time into the first temperature zone, and exit time of the first temperature zone of the adhesive product material with its temperature distribution data in the first temperature zone in real time to form a first association data group, and to establish a spatiotemporal mapping table based on multiple association data groups. The curing time acquisition module acquires the correlation data of the first unit segment of the adhesive product material in the first temperature zone based on the spatiotemporal mapping table, and adjusts the curing time of the first unit segment of the adhesive product material in the second temperature zone according to the correlation data of the first unit segment in the first temperature zone. The speed adjustment module is used to adjust the moving speed of the adhesive product material in the curing oven based on the curing time of the first unit segment of the adhesive product material in the second temperature zone; wherein, the moving speed is adjusted when there is a preset deceleration distance from the second temperature zone, and the production of the adhesive product is controlled according to the adjusted moving speed of the adhesive product; along the moving direction of the adhesive product, the second temperature zone is the next temperature zone after the first temperature zone.
