Description

Technical Field

[0001] This invention relates to the field of hot melt processing technology, and in particular to a method and system for dynamically adjusting the continuous hot melt parameters of an inflatable elastomer. Background Technology

[0002] In the production and manufacturing of various inflatable elastomer products such as inflatable paddleboards, inflatable boats, and inflatable airbags, the hot-melt pressing of the side panels and the main substrate is the core process that determines the airtightness, bonding strength, and service life of the product, and is directly related to the stability of product quality and the improvement of production efficiency.

[0003] Currently, the hot-melt pressing of inflatable elastomer belts is generally completed using gantry-type wire-feeding hot-melt machines. These machines mostly adopt an open-loop control mode with fixed temperature and fixed wire-feeding speed. Faced with differences in cold and hot machine conditions, speed reduction at large curvature corners, and other working conditions, it is difficult to maintain a balanced heat input per unit area, which can easily lead to defects such as incomplete welding, air leakage, fabric burn-through, or wrinkling at corners. At the same time, traditional production methods lack online quality monitoring mechanisms, and the pressing quality can only be passively detected by placing the finished product inflated.

[0004] Regarding the aforementioned technologies, in the actual hot-melt compaction process of inflatable elastomers, most existing technologies involve hot-melt operations with fixed machine tool temperature and processing speed. This results in incomplete melting (false welding, cold welding) or burn-through when the machine is first started or when the ambient temperature changes. Therefore, there is still room for improvement in the reliability of hot-melt compaction. Summary of the Invention

[0005] To improve the reliability of hot-melt compaction, this invention provides a method and system for dynamic adjustment of continuous hot-melt parameters of inflatable elastomers.

[0006] In a first aspect, the present invention provides a method for dynamically adjusting the continuous hot-melt parameters of an inflatable elastomer, employing the following technical solution: A method for dynamically adjusting the continuous hot-melt parameters of an inflatable elastomer includes: Step S1: In response to the preset hot melt signal, the temperature of the processing site and the initial temperature of the material are collected by the front sensor; Step S2: Use the processing site temperature and the initial material temperature as compensation information to determine the initial processing information; Step S3: Obtain the processing material number and perform hot melt processing operation on the processing material corresponding to the number according to the initial processing information; Step S4: During the hot melt processing operation, the temperature of the pressure roller weld is collected in real time; Step S5: Re-collect the processing site temperature and the initial material temperature, and adjust the initial processing information in conjunction with the pressure roller weld temperature to obtain updated processing information; Step S6: Continue the hot melt processing operation according to the updated processing information; Step S7: Repeat steps S4 to S6 to update the processing information until the preset processing completion signal is received, and then the finished product is obtained and output.

[0007] By adopting the above technical solution, processing is performed based on initial processing information. Then, the temperature of the pressure roller weld is collected during the processing to adjust the processing information in real time. The processing information is continuously adjusted and hot-melt processing is performed, so that the power of hot-melt compaction can be adjusted in real time according to the temperature, avoiding overheating or underheating of hot-melt welding due to temperature changes, thus improving the reliability of hot-melt compaction.

[0008] Optionally, it also includes a method for determining whether to adjust the updated processing information, the method comprising: Step S70: Obtain the standard temperature range and compare it with the temperature of the pressure roller weld to obtain the abnormal temperature; Step S71: Obtain temperature influence information, which includes stable change information and unknown change information; Step S720: If the temperature influence information is stable change information, re-collect the processing site temperature and the initial material temperature, and adjust the updated processing information in combination with the abnormal temperature to obtain updated processing information; Step S721: If the temperature influence information is unknown change information, do not adjust the updated processing information and record the abnormal location of the abnormal temperature until the abnormal temperature no longer exists; Step S722: Arrange all abnormal locations in chronological order to form abnormal welding segments; Step S723: Collect the temperature of the abnormal welded section to be repaired to determine the repair welding process information; Step S724: Perform hot melt processing on the abnormal welded section according to the repair welding information.

[0009] By adopting the above technical solution, the abnormal temperature is identified by comparing the real-time collected temperature of the pressure roller weld with the standard temperature range. Then, the parameter control strategy is selected differently based on the temperature influence information, avoiding welding defects caused by blindly adjusting parameters under irregular temperature disturbances, and improving the flexibility and reliability of parameter adjustment for hot melt compaction.

[0010] Optionally, methods for performing hot-melt processing on abnormal weld sections include: Step S7240: Upon receiving a preset welding repair signal, obtain the pressure roller number to determine the pressure roller pressing point and combine it with the welding start point in the abnormal welding section to determine the pressure roller pressing section; Step S7241: Obtain the actual pressing segment and determine the pressure roller contraction segment in combination with the pressing segment of the pressure roller; Step S7242: Control the pressure roller corresponding to the pressure roller number to perform a moving operation according to the welding start point and a pressure roller shrinking operation according to the pressure roller shrinking section; Step S7243: After the moving operation and the pressure roller retraction operation are completed, perform hot melt processing operation on the abnormal welding section according to the welding repair processing information; Step S7244: During the hot melt processing operation, the current position of the pressure roller is acquired in real time to analyze the contact with the normal section; Step S7245: If the normal segment is not touched, control the pressure roller corresponding to the pressure roller number to cancel the pressure roller retraction operation; Step S7246: Repeat steps S7244 to S7245 until the normal segment is touched again, obtain the welding end point of the abnormal welding segment and combine it with the current position of the pressure roller to obtain the shrinkage update segment; Step S7247: Control the pressure roller corresponding to the pressure roller number to perform the pressure roller shrinkage operation according to the shrinkage update section until the hot melt processing operation is completed at the welding endpoint.

[0011] By adopting the above technical solution, the pressing area of ​​the pressure roller is accurately located according to the pressure roller number, and the shrinkage section of the pressure roller is dynamically determined in combination with the start and end positions of the abnormal welding section. During the repair welding process, the position of the pressure roller is monitored in real time to determine whether it has contacted the normal welding area. The shrinkage control strategy of the pressure roller is adaptively adjusted to avoid the pressure roller accidentally squeezing the formed normal weld and causing damage, thereby improving the accuracy and reliability of hot melt repair welding.

[0012] Optionally, methods for performing the pressure roller retraction operation include: Step S72420: Obtain the starting point of the pressure roller contraction in the pressure roller contraction section; Step S72421: Compare the starting point of the pressure roller shrinkage with the starting point of the welding to analyze the offset distance of the pressure roller; Step S72422: Control the pressure roller corresponding to the pressure roller number to perform a rotation operation according to the pressure roller offset distance; Step S72423: During the rotation operation, control the pressure roller corresponding to the pressure roller number to perform a movement operation according to the welding start point and perform a pressure roller shrinkage operation according to the pressure roller shrinkage section.

[0013] By adopting the above technical solution, the offset distance of the pressure roller is calculated by comparing the starting point of the pressure roller's contraction with the starting point of the welding. Based on the offset distance, the pressure roller is controlled to rotate and correct its deviation, which is synchronized with the movement and contraction of the pressure roller. This prevents problems such as uneven pressure and compaction during the welding process, and improves the pressing and positioning accuracy of the pressure roller and the processing stability and reliability of hot melt welding.

[0014] Optionally, methods for obtaining the pressure roller number include: Step S72400: Use the abnormal welding segment as a search term to find the corresponding pressure roller candidate number and extract the corresponding pressure roller circumference; Step S72401: Determine the abnormal length based on the abnormal welding segment and divide it by the circumference of the pressure roller to obtain the length ratio, wherein the length ratio includes an integer ratio and a decimal ratio; Step S72402: If the length ratio is an integer ratio, the candidate number of the pressure roller is defined as the pressure roller number and output after receiving the welding signal; Step S72403: If the length ratio is a decimal ratio, obtain the number of retractable segments of the candidate pressure roller corresponding to the candidate pressure roller number and calculate the single segment ratio in combination with the pressure roller circumference; Step S72404: Use the single segment ratio and decimal ratio as search terms to determine the pressure roller number from the pressure roller candidate numbers.

[0015] By adopting the above technical solution, the corresponding candidate pressure roller number and pressure roller circumference are matched according to the length of the abnormal welded section. Different selection logics are distinguished by the length ratio, so as to realize intelligent selection of pressure roller based on the length of the welded section and improve the reliability of hot melt compaction.

[0016] Optionally, it also includes a method for adjusting the updated processing information even when the temperature influence information is unknown, the method comprising: Step S7210: Real-time acquisition of changing temperatures to obtain the lowest ambient temperature and record the time point of the lowest temperature; Step S7211: Obtain the starting time point of temperature influence information; Step S7212: Calculate the temperature change time by combining the lowest temperature time point and the starting time point; Step S7213: Analyze the temperature change based on the temperature change time, including instantaneous changes and delayed changes; Step S7214: If the temperature change is a delayed change, re-collect the processing site temperature and the initial material temperature, and adjust the updated processing information in combination with the abnormal temperature to obtain updated processing information; Step S7215: If the temperature change is instantaneous, do not adjust the updated processing information.

[0017] By adopting the above technical solution, the minimum ambient temperature and its corresponding time point are collected, and the duration of temperature change is calculated by combining the starting time point of temperature influence. This allows for differentiated adjustment of process parameters between instantaneous and delayed temperature change conditions, avoiding the drawbacks of blindly adjusting or not adjusting parameters at all under unknown temperature disturbances, and improving the comprehensiveness and reliability of parameter control for hot melt processing of inflatable elastomers.

[0018] Optionally, if the temperature change is a delayed change, the methods for adjusting the updated processing information include: Step S72140: Obtain humidity information; Step S72141: Analyze the degree of temperature influence based on humidity information; Step S72142: Generate and output an active intervention signal based on the degree of temperature influence; Step S72143: Upon receiving a preset confirmation signal, re-collect environmental information and adjust and update processing information.

[0019] By adopting the above technical solution, environmental humidity data is introduced to comprehensively determine the impact of temperature and humidity on hot melt processing under slow temperature changes, and an active intervention prompt signal is issued. After the operator confirms that the environmental control is completed, the environmental parameters are collected again to optimize the processing technology, avoiding the deviation of parameter adjustment in a single temperature dimension, and improving the accuracy of hot melt parameter adjustment and processing stability of inflatable elastomers.

[0020] Optional, also includes: Step S72144: If no confirmation signal is received, adjust the updated processing information based on the changing temperature and humidity information; Step S72145: Repeat steps S7210 to S7213 to update the temperature change; Step S72146: Perform steps S7214 to S7215 according to the updated temperature change.

[0021] By adopting the above technical solution, the processing parameters are automatically optimized based on real-time temperature and humidity data without receiving confirmation signals from the operator. At the same time, the temperature change conditions are updated cyclically and the corresponding parameter control strategies are rematched, realizing flexible switching between manual intervention and automatic parameter adjustment modes, and improving the adaptability and reliability of dynamic adjustment of continuous hot melt parameters of inflatable elastomers.

[0022] Optionally, methods for adjusting updated processing information also include: Step S770: Obtain historical temperatures; Step S771: When the changed temperature is less than the historical temperature, proceed from step S720 to step S721; Step S772: When the changed temperature is not less than the historical temperature, adjust the updated processing information by combining the changed temperature, the initial temperature of the material and the temperature of the pressure roller weld.

[0023] By adopting the above technical solution, the current temperature change is compared with the historical temperature to distinguish the temperature rise and fall conditions, thereby realizing differentiated process control under different temperature change trends and improving the comprehensiveness and reliability of the adjustment of the hot melt parameters of the gas-filled elastomer.

[0024] Secondly, the present invention provides a dynamic adjustment system for continuous hot-melt parameters of an inflatable elastomer, which adopts the following technical solution: A dynamic adjustment system for continuous hot-melt parameters of an inflatable elastomer includes: The acquisition module is used to acquire information such as processing site temperature, initial material temperature, pressure roller weld temperature, standard temperature range, temperature influence information, and humidity information. The memory is used to store the program for a method of dynamically adjusting the continuous hot-melt parameters of an inflatable elastomer as described above; The processor loads and executes programs from memory.

[0025] By adopting the above technical solution, the module collects parameters such as the temperature of the processing site in real time, the memory stores the complete dynamic adjustment program of the hot melt parameters, and the processor runs the program to realize the real-time adaptive adjustment of the process parameters, avoiding welding defects caused by temperature fluctuations and improving the intelligence and reliability of continuous hot melt processing of gas-filled elastomers.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: 1. Processing is performed based on initial processing information. During the processing, the temperature of the pressure roller weld is collected to adjust the processing information in real time. The processing information is continuously adjusted and hot melt processing is performed, so that the power of hot melt compaction can be adjusted in real time according to the temperature. This avoids overheating or underheating of hot melt welding due to temperature changes, thus improving the reliability of hot melt compaction. 2. By controlling the shrinkage of the pressure roller, the material that has already been properly welded is not affected during the repair welding process, thus improving the reliability of hot melt compaction; 3. By differentiating temperature changes, it can determine whether parameter adjustments are needed, avoiding irreversible damage caused by blindly adjusting parameters due to sudden temperature changes, which could lead to overheating during subsequent welding. This improves the reliability and flexibility of hot melt compaction. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] This invention discloses a method for dynamically adjusting the continuous hot-melt parameters of an inflatable elastomer. (Refer to...) Figure 1 A method for dynamically adjusting the continuous hot-melt parameters of an inflatable elastomer includes: Step S1: In response to the preset hot melt signal, the temperature of the processing site and the initial temperature of the material are collected by the front sensor.

[0031] The heat melt signal refers to the signal that triggers the continuous heat melt processing of the inflatable elastomer 2. The response to the heat melt signal is either via an electrical signal button on the heat melt device of the entire inflatable elastomer 2, which is pressed by the user, or via the system receiving signals from the operator through a human-machine interface touchscreen.

[0032] The processing area temperature refers to the ambient air temperature of the workshop or workstation where the hot-melt processing takes place. This temperature is collected in real-time by an infrared temperature sensor installed in front of the hot air or high-frequency emission port of the hot-melt machine head by a person skilled in the art. The initial material temperature refers to the actual surface temperature of the seam between the sheath and the outer membrane of the inflatable elastomer 2 before it is heated by the hot air, prior to the start of the hot-melt processing. This initial material temperature is also collected in real-time by an infrared temperature sensor installed in front of the hot air or high-frequency emission port of the hot-melt machine head by a person skilled in the art.

[0033] Step S2: Use the processing site temperature and the initial material temperature as compensation information to determine the initial processing information.

[0034] Compensation information refers to a set of reference data used to correct and compensate for the initial parameters of hot melt processing. Initial processing information refers to the initial settings for hot melt processing calculated based on the compensation information, such as core operating parameters like initial heating power, initial wire feed speed, and initial pressure. The initial processing information is determined by the system defining the collected processing site temperature and initial material temperature as compensation information, and then substituting them into a temperature-power mapping model to calculate parameters such as initial heating power, initial wire feed speed, and initial pressure adapted to the current environment and material state.

[0035] Step S3: Obtain the processing material number and perform hot melt processing operation on the processing material corresponding to the number according to the initial processing information.

[0036] The processing material number refers to the unique number of the processing material for the inflatable elastomer 2. This processing material number can be obtained by the user selecting it from the material list via a human-machine interface touchscreen or manually entering the number, or by automatically identifying the material number by scanning the code on the material roll with a barcode scanner.

[0037] The hot-melt processing operation refers to the continuous process of heating the polymer coating at the joint between the sheath and the outer membrane of the inflatable elastomer 2 to a molten state, and then applying pressure through the pressure roller 1 to make the molten interface penetrate and bond together, ultimately forming an airtight seal weld. The hot-melt processing operation is performed as follows: the system sets the hot air heating power and wire feed speed according to the initial processing information, starts the hot air generator to spray high-temperature hot air at the joint between the sheath and the outer membrane to melt the surface coating, and simultaneously, the pressure roller 1 follows closely behind the hot air with a set pressure to roll and bond the molten interface. The driving mechanism moves the machine head along the contour of the inflatable elastomer 2 at a uniform speed, heating and pressing simultaneously, continuously completing the hot-melt seal welding of the sheath and the outer membrane.

[0038] Step S4: During the hot melt processing operation, the temperature of the pressure roller weld is collected in real time.

[0039] The weld temperature of the pressure roller refers to the actual surface temperature of the weld that has just been pressed by pressure roller 1. The weld temperature of the pressure roller is collected by installing a rear infrared temperature sensor on the discharge side of the pressure roller 1 of the hot melt machine head along the direction of travel. The temperature probe of the sensor is aimed at the surface of the weld that has just been pressed by pressure roller 1, and the surface temperature of the weld is collected in real time and continuously in a non-contact manner according to the sampling frequency.

[0040] When the hot melt processing operation is performed, it indicates that the entire device has performed hot melt welding on the shroud and the inflatable elastomer 2 according to the initial processing information. At this time, the temperature of the pressure roller weld is collected in real time.

[0041] Step S5: Re-collect the processing site temperature and the initial material temperature, and adjust the initial processing information in conjunction with the pressure roller weld temperature to obtain updated processing information.

[0042] Updating processing information refers to obtaining the latest process parameters after dynamically correcting the initial processing information. This updated processing information is obtained through the system's CNC central control unit (PLC or host computer). On one hand, it calculates the deviation between the real-time collected pressure roller weld temperature and the target melting temperature, and combines this with the newly collected processing site temperature and the initial material temperature to calculate the temperature closed-loop parameter adjustment. On the other hand, it reads the real-time feedback of the die head's movement speed. When encountering a corner and slowing down, it adjusts the heat-melting power proportionally in milliseconds according to the constant enthalpy mathematical model to ensure that the total heat received per unit area remains constant. Finally, it fuses the temperature closed-loop adjustment and the speed feedforward adjustment to dynamically correct the initial processing information, obtaining updated processing information including parameters such as heating power, wire feed speed, and pressure. Here, the constant enthalpy mathematical model can be Q=P / v, where Q is the heat input per unit welding area, P is the heat-melting power, and v is the die head movement speed.

[0043] Step S6: Continue the hot melt processing operation according to the updated processing information.

[0044] The hot melt processing operation here continues by the system seamlessly sending the updated heating power, wire feed speed, pressure and other processing parameters to the hot air generator drive module, drive walking mechanism and pressing pneumatic adjustment module through the real-time communication bus. Without interrupting the hot melt processing process, the operating parameters of each execution unit are dynamically adjusted to keep the weld temperature stable in the optimal fusion range, while keeping the machine head moving continuously along the contour of the inflatable elastomer 2.

[0045] Step S7: Repeat steps S4 to S6 to update the processing information until the preset processing completion signal is received, and then the finished product is obtained and output.

[0046] The update method for processing information here involves the system repeatedly collecting the temperature of the pressure roller weld, updating the processing site temperature and the initial material temperature, performing real-time temperature deviation calculations and speed feedforward calculations, and correcting processing parameters until the entire circumference of the webbing is hot-melted and pressed together, and the finished product is output. The processing completion signal is a control signal indicating the end of the entire circumference hot-melt pressing process. The processing completion signal is received automatically by the system when the position encoder or vision positioning module detects that the machine head has reached the processing endpoint and completed the entire circumference hot-melt pressing.

[0047] The finished product refers to the semi-finished product of the inflatable elastomer 2, in which the outer membrane of the sheath and the inflatable elastomer 2 have been heat-fused to form a complete airtight sealed cavity. The finished product is obtained by the system receiving a processing completion signal, controlling the hot air generator to stop heating, the traveling mechanism to stop moving, the pressure roller 1 to lift, and the tooling fixture to loosen. At this point, the outer membrane of the sheath and the inflatable elastomer 2 has been continuously heat-fused to form a complete airtight sealed cavity, thus obtaining the finished product. The finished product is output by the system automatically lifting the pressure roller 1 and loosening the tooling fixture after completing the heat-fusion process, notifying the operator to remove the finished product via audible and visual prompts, or transferring the finished product to the next valve installation or airtightness testing process via an automatic conveyor mechanism. Simultaneously, the system outputs complete process data for this processing, such as weld temperature curves, traveling speed records, and abnormal weld section location markers.

[0048] Reference Figure 2 It also includes a method for determining whether to adjust the updated processing information, the method comprising: Step S70: Obtain the standard temperature range and compare it with the temperature of the pressure roller weld to obtain the abnormal temperature.

[0049] The standard temperature range refers to the weld temperature interval that ensures the qualified quality of the heat fusion between the outer membrane and the outer cladding. The standard temperature range is obtained by having different standard temperature ranges for different processing materials. This range is determined experimentally by those skilled in the art, then bound to the processing material number and input into the system. When the system receives the processing material number, it automatically retrieves the corresponding standard temperature range.

[0050] Abnormal temperature refers to the temperature of the pressure roller weld that exceeds the standard temperature range. The abnormal temperature is obtained by the system comparing the real-time collected pressure roller weld temperature value with the upper and lower thresholds of the standard temperature range one by one. When the pressure roller weld temperature is lower than the lower limit, it is determined to be an underheating abnormal temperature; when the pressure roller weld temperature is higher than the upper limit, it is determined to be an overheating abnormal temperature. Simultaneously, the specific value of the abnormal temperature, the time of occurrence, and other information are recorded.

[0051] Step S71: Obtain information on the effects of temperature.

[0052] Temperature impact information refers to the classification and judgment information that distinguishes the types of interference factors causing abnormal changes in the temperature of the pressure roller weld. Temperature impact information includes stable change information and unknown change information. The system obtains this information through multiple channels to comprehensively judge its type. Firstly, it obtains current weather information (such as whether it's raining or sunny with strong sunlight) through a network weather interface, or detects sunlight intensity through a workshop light sensor, or detects the trend of environmental temperature and humidity changes through a temperature and humidity sensor. These predictable and stable environmental factors are classified as stable change information. Secondly, it detects sudden changes in workshop wind speed through a wind speed sensor, or calculates the rate of change of the pressure roller weld temperature, classifying sudden, rapidly changing, and uncertain-duration gusts as unknown change information. Stable change information refers to the classification information of temperature interference factors that are continuously stable, have a slow rate of change, and are predictable, such as: slow changes in environmental temperature and humidity, continuous sunlight in the workshop, and continuous rain. Unknown change information refers to the classification information of temperature interference factors that are sudden, have a fast rate of change, and have uncertain duration, such as: sudden gusts of wind, or airflow brought in by the sudden opening of the workshop door.

[0053] Step S720: If the temperature influence information is stable change information, re-collect the processing site temperature and the initial material temperature, and adjust the updated processing information in combination with the abnormal temperature to obtain updated processing information.

[0054] If the temperature effect information is stable, it means that the temperature change is slow and sufficient to make a change response. There is no need to worry about overheating caused by sudden temperature changes. Therefore, the processing site temperature and the initial material temperature are collected again and combined with the abnormal temperature to adjust the updated processing information to obtain updated processing information.

[0055] Step S721: If the temperature influence information is unknown change information, do not adjust the updated processing information and record the abnormal position of the abnormal temperature until the abnormal temperature no longer exists.

[0056] An abnormal location refers to a specific weld section where underheating or overheating is observed. This abnormal location is recorded by the system using a position encoder to collect the machine head's travel position coordinates in real time. When the temperature of the pressure roller weld exceeds the standard temperature range, the corresponding position of the machine head is immediately recorded as the abnormal location.

[0057] If the temperature impact information is unknown, it means that the temperature is changing rapidly and it is impossible to know whether it will change suddenly again. In order to avoid blindly adjusting the power and causing irreversible overheating, the processing information will not be updated and the abnormal temperature will be recorded until the abnormal temperature no longer exists.

[0058] Step S722: Arrange all abnormal locations in chronological order to form abnormal welding segments.

[0059] An abnormal welding segment refers to an abnormal weld section formed by arranging and merging all recorded abnormal locations according to the machine head's movement sequence. The abnormal welding segment is formed by the system sorting all recorded abnormal locations according to the machine head's movement sequence or the sequence of position coordinates, merging adjacent abnormal points into continuous abnormal welding segments. Each abnormal welding segment includes attribute information such as start point position, end point position, segment length, abnormality type, and minimum or maximum temperature.

[0060] Step S723: Collect the temperature of the abnormal welded section to be repaired to determine the repair welding process information.

[0061] The temperature to be repaired refers to the actual surface temperature of the material in the abnormal welding section before the repair welding operation begins. The method for collecting the temperature to be repaired is as follows: before the repair welding operation begins, the system controls the machine head to move to the starting position of the abnormal welding section, and uses a front-mounted infrared temperature sensor to measure the surface temperature of the weld in the area to be repaired at multiple points, and takes the average value as the temperature to be repaired; or the temperature is collected along the entire temperature measurement path along the abnormal welding section.

[0062] Repair welding information refers to the set of specialized process parameters used when repairing abnormal weld sections, including repair welding heating power, repair welding wire feed speed, and repair welding pressure. The repair welding information is determined by the system using information such as the temperature to be repaired, the type of abnormality in the abnormal weld section, the process parameters corresponding to the processing material number, and the temperature record of the first weld, combined with a dedicated temperature-power mapping model for repair welding. This model calculates the appropriate repair welding heating power, repair welding wire feed speed, and repair welding pressure. The temperature-power mapping model can be Pb = P0 + k(T0 − Tb), where Pb is the repair welding heating power, P0 is the baseline standard heating power, k is the material temperature compensation coefficient, T0 is the standard process temperature, and Tb is the temperature to be repaired.

[0063] Step S724: Perform hot melt processing on the abnormal welded section according to the repair welding information.

[0064] The hot melt processing operation here is performed as follows: the system controls the machine head to move to the starting position of the abnormal welding section, sets the welding heating power, welding wire feed speed and welding pressure according to the welding repair information, and controls the retractable pressure roller 1 to retract the part of the pressure roller 1 corresponding to the normal weld area to avoid pressing on the already welded normal area. Then, the hot air fan is started to heat the abnormal welding section, and the machine head is controlled to move at a constant speed along the abnormal welding section. The pressure roller 1 follows the hot air and rolls and adheres to the weld. During the movement, the welding temperature of the welding pressure roller is collected in real time and the power is finely adjusted until the end position of the abnormal welding section is reached, then the heating is stopped and the pressure roller 1 is lifted to complete the single-segment welding operation.

[0065] Reference Figure 3 Methods for performing hot-melt processing on abnormal welded sections include: Step S7240: Upon receiving a preset welding repair signal, obtain the pressure roller number to determine the pressure roller pressing point and combine it with the welding start point in the abnormal welding section to determine the pressure roller pressing section.

[0066] The repair welding signal is the signal that triggers the start of repair welding operations for abnormal welding sections. The repair welding signal is received by the system automatically detecting the presence of abnormal welding section records after completing a full cycle of normal hot melt processing. If an abnormal welding section record is found, a repair welding signal is automatically generated. Alternatively, the user can manually trigger the repair welding signal by pressing the repair welding button after viewing the abnormal welding section record and quality assessment through the human-machine interface.

[0067] The pressure roller number refers to the unique number of the pressure roller 1 used for repairing abnormal welded sections. The method for obtaining this pressure roller number is as follows: each pressure roller 1 has a unique number, which is set and entered into the system by those skilled in the art. Then, the system searches for matching pressure roller 1s and automatically obtains the corresponding pressure roller number based on parameters such as the length, position, and curvature of the abnormal welded section.

[0068] The pressure roller pressing point refers to the point on the surface of pressure roller 1 where it applies pressure to the weld. This pressure roller pressing point is determined by the system based on the real-time movement position of the machine head, identifying the point where pressure roller 1 will currently contact the material. The welding start point refers to the initial coordinates of the location where repair welding is required in the abnormal welding section; it is also the starting point for the machine head to perform the repair welding hot-melt process. This welding start point is determined by the system retrieving previously stored abnormal welding section location data.

[0069] The pressing section of the pressure roller refers to the area on the surface of the pressure roller 1 that is in contact with and pressed against the material to be welded. The pressing section of the pressure roller is determined by the system using the pressing point of the pressure roller as the initial alignment reference of the pressure roller 1 to delineate a continuous range in which the pressure roller 1 can stably contact the material after pressing down.

[0070] When a repair welding signal is received, it indicates that repair welding is about to begin. At this time, the pressure roller number is obtained to determine the pressure roller pressing point, and the pressure roller pressing section is determined by combining the welding starting point in the abnormal welding section.

[0071] Step S7241: Obtain the actual pressing section and determine the pressure roller contraction section in combination with the pressing section of the pressure roller.

[0072] The actual pressing segment refers to the actual contact area between the material and the surface of the workpiece to be welded after the pressure roller 1 presses down. The actual pressing segment is obtained by aligning the pressure roller pressing point with the welding start point, and then using the pressure roller pressing segment as a comparison to obtain the actual material pressing segment.

[0073] The pressure roller contraction section refers to the pressure roller area where a contraction action is required to prevent pressure roller 1 from pressing against the already welded normal weld area. The pressure roller contraction section is determined by the system comparing the real-time acquired actual pressing section with the pressure roller pressing section, and identifying the contact area falling within the normal weld area as the pressure roller contraction section.

[0074] Step S7242: Control the pressure roller 1 corresponding to the pressure roller number to perform a moving operation according to the welding start point and a pressure roller shrinking operation according to the pressure roller shrinking section.

[0075] The movement operation refers to the process of controlling the machine head equipped with pressure roller 1 to move to the welding start point. This movement operation is executed by the system first using a position encoder to locate the current coordinates of the machine head in real time, calculating the displacement deviation between the current position and the welding start point of the abnormal welding section, and then driving the traveling mechanism to precisely move the machine head to the welding start point position to complete alignment. The pressure roller retraction operation refers to retracting the pressure roller retraction section, retaining only the control action of pressing the pressure roller area of ​​the abnormal welding section. This retraction operation is executed by the system issuing a retraction drive command based on the determined pressure roller retraction section to retract it, avoiding contact with the material surface.

[0076] Step S7243: After the moving operation and the pressure roller retraction operation are completed, perform hot melt processing operation on the abnormal welding section according to the welding repair processing information.

[0077] Once the moving operation and the pressure roller retraction operation are completed, it means that the abnormal welded section can be directly compacted without worrying about compacting the normal area. Therefore, the hot melt processing operation is performed on the abnormal welded section according to the repair welding processing information.

[0078] Step S7244: During the hot melt processing operation, the current position of the pressure roller is acquired in real time to analyze the situation of contact with the normal section.

[0079] The current position of the pressure roller refers to the current coordinate point of the weld seam where pressure roller 1 is located. The current position of the pressure roller is obtained by the system continuously collecting the travel displacement data by the position encoder mounted on the machine head, and combining it with the initial welding starting point coordinates to calculate the real-time position coordinates of pressure roller 1 to obtain the current position of the pressure roller.

[0080] "Touching the normal section" refers to a situation where the current position of pressure roller 1 poses a risk of crushing the normal area. The analysis method for this situation involves the system continuously comparing the real-time collected current position of the pressure roller with the start and end coordinates of the abnormal welding section. As the machine head rolls along the weld seam, it continuously determines whether the actual pressing area covered by pressure roller 1 touches the normal weld seam area to determine the "touching the normal section" situation.

[0081] When the hot melt processing operation is executed, it indicates that the abnormal welding section has begun to be repaired. Therefore, the current position of the pressure roller is obtained in real time to analyze the situation of touching the normal section.

[0082] Step S7245: If the normal segment is not touched, control the pressure roller 1 corresponding to the pressure roller number to cancel the pressure roller retraction operation.

[0083] If the normal section is not touched, it means that the normal area at the starting point will no longer be compacted. Therefore, the pressure roller 1 corresponding to the control pressure roller number is canceled from performing the pressure roller shrinkage operation.

[0084] Step S7246: Repeat steps S7244 to S7245 until the normal segment is touched again, obtain the welding endpoint of the abnormal welding segment and combine it with the current position of the pressure roller to obtain the shrinkage update segment.

[0085] The welding endpoint refers to the coordinates of the final position of the abnormal welding section requiring re-welding. The welding endpoint is determined by the system retrieving previously stored abnormal welding section position data to obtain the welding endpoint for this re-welding operation. The shrinkage update section refers to the contact area where pressure roller 1 needs to re-perform shrinkage when it reaches the vicinity of the welding endpoint of the abnormal welding section. The shrinkage update section is obtained by the system comparing the current position of the pressure roller with the welding endpoint of the abnormal welding section, defining the pressing area within the normal weld seam range after the welding endpoint as the shrinkage update section.

[0086] Step S7247: Control the pressure roller 1 corresponding to the pressure roller number to perform the pressure roller shrinkage operation according to the shrinkage update section until the hot melt processing operation is completed at the welding endpoint.

[0087] The pressure roller retraction operation here is performed as follows: the system locks the portion of pressure roller 1 within the determined retraction update segment that needs to be retracted, drives the corresponding portion to retract, and only retains the portion within the abnormal welding segment to extend and press, until the welding endpoint is repaired and the roller is lifted, at which point the retraction is canceled. The above steps can be referred to as... Figure 4 The pressure roller 1 is placed above the pneumatic elastomer 2. At this point, assume A and C are normal welded sections without abnormalities, B is a welded section with abnormalities, X is the rolling direction of the pressure roller 1, a is the starting point of the abnormal section of the pneumatic elastomer 2 relative to the rolling direction, and b is the ending point of the abnormal section of the pneumatic elastomer 2 relative to the rolling direction. When the pressure roller 1 moves along the rolling direction, it performs a contraction operation on the sections whose compaction range extends to the normal welded area, only keeping the portion corresponding to the abnormal welded section extended and compacted. When the pressure roller 1 moves to a point where it no longer presses on the normal welded area, the contraction of that portion is released, and it extends again. When it moves to near the end point and re-enters the normal area, the corresponding portion contracts again.

[0088] The methods for performing the pressure roller retraction operation include: Step S72420: Obtain the starting point of the pressure roller contraction in the pressure roller contraction section.

[0089] The starting point of the pressure roller contraction refers to the pressing point within the contraction section of the pressure roller that is closest to the welding start point and requires the contraction action to be performed. The starting point of the pressure roller contraction is obtained by the system calling the structural parameters of the current pressure roller 1, parsing the number of independently controllable contraction segments of pressure roller 1, and combining this with the current rotation position of pressure roller 1 to filter out the point corresponding to the segment to be contracted closest to the welding start point.

[0090] Step S72421: Compare the starting point of the pressure roller shrinkage with the starting point of the welding to analyze the offset distance of the pressure roller.

[0091] The offset distance of the pressure roller refers to the rolling arc length that the pressure roller 1 travels along the weld when it rotates from the starting point of the pressure roller's contraction to the starting point of the welding. The offset distance of the pressure roller is determined by the system calculating the rotational central angle required for the starting point of the pressure roller's contraction to align with the starting point of the welding, and then converting the corresponding rolling arc length into the radius of the pressure roller 1 to obtain the offset distance of the pressure roller.

[0092] Step S72422: Control the pressure roller 1 corresponding to the pressure roller number to perform a rotation operation according to the pressure roller offset distance.

[0093] The rotation operation refers to the action of driving pressure roller 1 to rotate according to the offset distance of the pressure roller. The rotation operation is executed by the system calculating the target rotation angle of pressure roller 1 based on the offset distance of the pressure roller, and sending a rotation control command to the driving mechanism of pressure roller 1 to drive pressure roller 1 to rotate to the corresponding position.

[0094] Step S72423: During the rotation operation, control the pressure roller 1 corresponding to the pressure roller number to perform a movement operation according to the welding start point and perform a pressure roller shrinkage operation according to the pressure roller shrinkage section.

[0095] When the rotation operation is performed, it indicates that the pressure roller 1 is about to retract and repair the abnormal welding section. At this time, the pressure roller 1 corresponding to the control pressure roller number performs a movement operation according to the welding start point and a pressure roller retraction operation according to the pressure roller retraction section.

[0096] The methods for obtaining the pressure roller number include: Step S72400: Use the abnormal welding segment as a search term to find the corresponding pressure roller candidate number and extract the corresponding pressure roller circumference.

[0097] The candidate pressure roller number refers to the pressure roller number suitable for this repair welding operation. The method for extracting the candidate pressure roller number here is that the system uses the characteristic parameters of the abnormal welding section as search conditions and filters out pressure roller numbers with matching parameters as candidate pressure roller numbers. The pressure roller circumference refers to the total length of the outer circumference of pressure roller 1. The method for extracting the pressure roller circumference here is that different pressure rollers 1 correspond to different parameters, which are determined by those skilled in the art based on the rated parameters of pressure roller 1 at the factory and input into the system. Then, the system directly retrieves the corresponding outer diameter parameters based on the number to obtain the pressure roller circumference.

[0098] Step S72401: Determine the abnormal length based on the abnormal welded section and divide it by the circumference of the pressure roller to obtain the length ratio.

[0099] The abnormal length refers to the length of the segment where welding anomalies occur. This abnormal length is obtained by the system accumulating its own traveled length while recording the abnormal welding segment, and then using that length as the abnormal length. The length ratio is the value obtained by dividing the total length of the abnormal welding segments by the circumference of the current candidate pressure roller. This length ratio includes both integer and decimal ratios. The length ratio is calculated by the system reading the stored values ​​of the abnormal welding segment length and the pressure roller circumference, and then performing a division operation.

[0100] Step S72402: If the length ratio is an integer ratio, the candidate number of the pressure roller is defined as the pressure roller number and output after receiving the welding signal.

[0101] The output method for the pressure roller number here is that the system determines the pressure roller candidate number that only contains an integer part and has no decimal part as the final pressure roller number used in this repair welding operation. After the system receives the repair welding trigger signal, the number is transmitted to the pressure roller 1 drive control module to complete the output.

[0102] If the length ratio is an integer ratio, it means that the abnormal welding segment can be repaired by one roller. Therefore, the candidate number of the pressure roller is defined as the pressure roller number and output after receiving the repair welding signal.

[0103] Step S72403: If the length ratio is a decimal ratio, obtain the number of retractable segments of the candidate pressure roller corresponding to the candidate pressure roller number and calculate the single segment ratio in combination with the pressure roller circumference.

[0104] The number of retractable segments refers to the number of segments of pressure roller 1 that can be independently controlled to extend or retract in the circumferential direction. The number of retractable segments is obtained by the system retrieving the segmentation parameters of pressure roller 1 based on the current candidate pressure roller number to obtain the corresponding number of retractable segments.

[0105] The single-segment ratio refers to the proportion of the arc length of a single retractable segment on pressure roller 1 to the total circumference of pressure roller 1. The single-segment ratio is calculated by dividing 1 by the number of retractable segments to obtain the arc length ratio of a single segment.

[0106] If the length ratio is a decimal ratio, it indicates that there may be pressure roller 1 that cannot meet the abnormal welding length. In order to remove it and obtain pressure roller 1 that meets the abnormal welding segment, the number of retractable segments of the candidate pressure roller corresponding to the candidate number of the pressure roller is obtained and the single segment ratio is calculated in combination with the circumference of the pressure roller.

[0107] Step S72404: Use the single segment ratio and decimal ratio as search terms to determine the pressure roller number from the pressure roller candidate numbers.

[0108] The method for determining the pressure roller number here is as follows: the system uses the decimal part of the calculated single-segment ratio and length ratio as the decimal ratio for matching and verification, and filters out the pressure roller candidate numbers whose decimal ratio is a multiple of the single-segment ratio to obtain the pressure roller number. For example: if the decimal ratio is 8.8, then the single-segment ratio of the first candidate pressure roller is 0.2, so the four segments of the first candidate pressure roller are 0.8, and thus the first candidate pressure roller is the pressure roller number.

[0109] This includes a method for adjusting the updated processing information even when the temperature influence information is unknown. This method includes: Step S7210: Real-time acquisition of changing temperatures to obtain the lowest ambient temperature and record the time point of the lowest temperature.

[0110] Varying temperature refers to the real-time dynamic fluctuation of temperature in the processing environment. The method for acquiring this varying temperature is to continuously collect ambient temperature data using temperature sensors placed at the workstation; the changing temperature is obtained when a change occurs.

[0111] The lowest ambient temperature refers to the minimum temperature value among all real-time temperature data collected by the temperature sensor within a continuous acquisition period. This lowest ambient temperature is obtained by the system iterating through and comparing multiple sets of continuously collected temperature data, selecting the temperature with the smallest value. The lowest temperature time point refers to the system timestamp corresponding to the moment the temperature sensor collected the lowest ambient temperature. This lowest temperature time point is recorded by the system simultaneously capturing and storing the current time information upon identifying the lowest ambient temperature.

[0112] Step S7211: Obtain the starting time point of temperature influence information.

[0113] The start time point refers to the initial system timestamp when the ambient temperature begins to affect the hot-melt welding process. The start time point is obtained by reading the initial time when the temperature effect takes effect, thus obtaining the start time point of the temperature effect information.

[0114] Step S7212: Calculate the temperature change time by combining the lowest temperature time point and the starting time point.

[0115] Temperature change time refers to the time interval between the start time of the temperature influence information and the time point corresponding to the lowest ambient temperature. The temperature change time is calculated by subtracting the timestamp of the start time from the timestamp corresponding to the lowest temperature, thus obtaining the temperature change time between the two time points.

[0116] Step S7213: Analyze the temperature change based on the time of temperature change.

[0117] Temperature change refers to the overall state of ambient temperature, including its fluctuation trend, temperature difference amplitude, and duration. Temperature change includes instantaneous and delayed changes. The analysis of temperature change here involves the system combining the initial ambient temperature at the start time, the lowest ambient temperature, and the calculated temperature change time to calculate the overall temperature difference and average temperature change rate within that time period, thus determining the temperature change during the processing. Instantaneous change refers to a rapid decrease in ambient temperature over a short period. Instantaneous change is determined by comparing the calculated average temperature change rate with a pre-set rate threshold set by the operator; instantaneous changes exceeding this threshold are considered to be true. Delayed change refers to a slow decrease in ambient temperature over a longer period. Delayed change is determined by comparing the calculated average temperature change rate with a pre-set rate threshold set by the operator; delayed changes are considered to be true.

[0118] Step S7214: If the temperature change is a delayed change, re-collect the processing site temperature and the initial material temperature, and adjust the updated processing information in conjunction with the abnormal temperature to obtain updated processing information.

[0119] If the temperature change is a delayed change, it means that the temperature is changing slowly, and the materials on the processing table are also slowly affected by the temperature. Therefore, the processing site temperature and the initial material temperature should be collected again and combined with the abnormal temperature to adjust the updated processing information to obtain updated processing information.

[0120] Step S7215: If the temperature change is instantaneous, do not adjust the updated processing information.

[0121] If the temperature change is instantaneous, it means that the ambient temperature of the entire workshop has changed abruptly. In order to avoid overheating caused by the instantaneous temperature change, the processing information will not be updated.

[0122] When the temperature change is a delayed change, the methods for adjusting the updated processing information include: Step S72140: Obtain humidity information.

[0123] Humidity information refers to the real-time relative humidity value of the air in the processing environment at the hot melt welding site. This humidity information is obtained by the system collecting real-time air humidity data in the work area through humidity sensors installed at the processing station.

[0124] Step S72141: Analyze the degree of temperature influence based on humidity information.

[0125] The degree of temperature influence refers to the strength of the interference caused by changes in ambient humidity coupled with temperature during the hot-melt welding process, affecting the material melting rate, weld cooling rate, and weld formation quality. The analysis of this degree of temperature influence involves the system inputting real-time humidity information, the current ambient temperature difference, and the rate of temperature change into a temperature-humidity coupled influence model. The model then classifies the influence into three levels: mild, moderate, and severe. The temperature-humidity coupled influence model can be represented as S = a*ΔT + b*RH + c*dT / dt, where S is the temperature-humidity coupled influence index, ΔT is the current ambient temperature difference, RH is the real-time humidity information, dT / dt is the rate of temperature change, a is the temperature difference weighting coefficient, b is the humidity weighting coefficient, and c is the rate of temperature change weighting coefficient.

[0126] Step S72142: Generate and output an active intervention signal based on the degree of temperature influence.

[0127] Active intervention signals refer to control command signals generated by the system based on the degree of temperature impact, reminding users to actively adjust temperature and humidity. The formation of these active intervention signals involves the system retrieving and integrating warning messages, audible and visual trigger parameters, and other information linked to mild, moderate, and severe temperature impact levels. This information is then packaged and used to remind operators to adjust the on-site temperature and humidity. The output of these active intervention signals involves the system transmitting the packaged signals to the equipment's human-machine interface display, the audible and visual alarm module, and the main control module of the hot-melt welding equipment, simultaneously providing text pop-up reminders, audible and visual warnings, and process parameter control commands.

[0128] Step S72143: Upon receiving a preset confirmation signal, re-collect environmental information and adjust and update processing information.

[0129] A confirmation signal is a feedback signal sent by the user to the system after receiving an intervention alert for abnormal temperature and humidity, indicating that they have acknowledged the alert and have completed the on-site temperature and humidity adjustment operation. This confirmation signal is obtained by the system in real-time monitoring of button trigger commands or interface confirmation click commands on the device's interactive interface.

[0130] Upon receiving a pre-set confirmation signal, it indicates that the staff has artificially interfered with the environment, such as by turning on a fan or air conditioner. Therefore, the environmental information is re-collected and the processing information is adjusted and updated.

[0131] This also includes: Step S72144: If no confirmation signal is received, adjust the updated processing information based on the changing temperature and humidity information.

[0132] If no confirmation signal is received, it indicates that the staff has not interfered with the environment. Therefore, the processing information is adjusted based on the changes in temperature and humidity.

[0133] Step S72145: Repeat steps S7210 to S7213 to update the temperature change.

[0134] The temperature change update method here is to repeatedly execute the entire process of real-time temperature change acquisition, determining the lowest ambient temperature and its corresponding time point, obtaining the starting time point of temperature influence, calculating the temperature change time, and determining the instantaneous or delayed temperature change based on the temperature change rate. The system then recalculates using the latest round of collected temperature and humidity data to obtain the updated temperature change and completes data overwrite storage.

[0135] Step S72146: Perform steps S7214 to S7215 according to the updated temperature change.

[0136] The method of execution based on temperature changes is as follows: the system re-determines whether the current temperature change is delayed or instantaneous based on the updated temperature change. If it is determined to be a delayed change, the process of acquiring humidity information, analyzing the degree of temperature influence, generating and outputting an active intervention signal, listening for confirmation signals, and adjusting and updating the processing information accordingly is executed in sequence. If it is determined to be an instantaneous change, the original processing parameters are kept unchanged, and no adjustment operation to update the processing information is performed.

[0137] The methods for adjusting updated processing information also include: Step S770: Obtain historical temperatures.

[0138] Historical temperature refers to the ambient temperature value that was last collected and stored by the temperature sensor. The historical temperature is obtained by the system directly reading the temperature data stored in the cache after the previous round of temperature collection.

[0139] Step S771: When the changed temperature is less than the historical temperature, proceed with steps S720 to S721.

[0140] When the temperature change is less than the historical temperature, it indicates that the temperature is decreasing. At this time, it is necessary to judge the temperature change, so steps S720 to S721 are executed.

[0141] Step S772: When the changed temperature is not less than the historical temperature, adjust the updated processing information by combining the changed temperature, the initial temperature of the material and the temperature of the pressure roller weld.

[0142] The method for updating processing information here is as follows: the system inputs the real-time collected current temperature changes, the initial temperature of the workpiece material, and the real-time temperature of the weld at pressure roller 1 into the hot melt process parameter correction model. Through multi-dimensional temperature data coupling calculation, the original heating power, equipment travel speed, pressure, and other processing parameters are corrected and replaced to generate a new parameter set adapted to the current temperature conditions to adjust the updated processing information. Here, the hot melt process parameter correction model can be P=P1+m*ΔT1+n*ΔT2+q*ΔT3, where P is the corrected hot melt heating power, P1 is the current baseline processing power, ΔT1 is the ambient temperature deviation, ΔT2 is the initial material temperature deviation, ΔT3 is the pressure roller weld temperature deviation, and m, n, and q are the corresponding temperature correction weight coefficients.

[0143] When the changing temperature is not less than the historical temperature, it indicates that the temperature is rising. In order to avoid overheating, the updated processing information is adjusted by combining the changing temperature, the initial temperature of the material, and the temperature of the pressure roller weld.
