Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic device manufacturing, and particularly to an optimization method for the production process of a safety interface of an electronic device based on fuzzy logic. Background Art
[0002] With the continuous development of electronic device manufacturing technology, the functional complexity and integration degree of electronic devices are also increasing continuously. Especially in the production process involving safety interfaces, the requirements for process control are becoming more and more strict. These safety interfaces not only need to ensure the stable operation of electronic devices under various environmental conditions, but also need to meet the requirements of high reliability, high performance and low energy consumption. To achieve these goals, the optimization of the production process is particularly important. However, in the prior art, there are still many deficiencies in the optimization methods for the production process of electronic device safety interfaces, and they cannot fully meet the needs of modern electronic manufacturing for efficient and high-precision production control.
[0003] In traditional production processes, fixed rules or simple experience-based adjustment methods are usually used to control production parameters. Although these methods can play a role in some cases, since the process parameters in the production process involve many variables, such as temperature, pressure, material flow rate, equipment load, etc., and the relationships between these variables are complex and uncertain, it is difficult for traditional methods to maintain the best process control state in a dynamically changing production environment. In addition, when dealing with changes in production requirements, fluctuations in equipment status or external environmental disturbances, traditional methods often lack flexibility and adaptability, which easily lead to problems such as low production efficiency, unstable product quality and excessive energy consumption.
[0004] To make up for these deficiencies, in recent years, some intelligent process control methods have been gradually applied to the field of electronic device manufacturing, such as intelligent optimization algorithms like fuzzy logic control, genetic algorithm optimization, particle swarm optimization and ant colony optimization. However, these methods usually only optimize at a single level or within a local range, lacking a global consideration of the entire production process. For example, although fuzzy logic can handle uncertainty and ambiguity, the design and optimization of its rule base often rely on expert experience and it is difficult to adapt to a complex and changeable production environment. Although intelligent algorithms such as genetic algorithms, particle swarm optimization and ant colony optimization have strong global search capabilities, in the production process, due to the lack of comprehensive consideration of multiple levels and multiple objectives, it is difficult to achieve comprehensive optimization from the global to the details. In addition, the data processing methods in the prior art are mostly static processing and cannot dynamically adapt to the volatility and real-time nature of data in the production process, resulting in limited response speed and control accuracy of the system.
[0005] In the prior art, there are also some limitations in data acquisition and monitoring technologies. Although the development of industrial Internet of Things and sensor technologies has made real-time data acquisition possible, this data is usually not optimized before being directly applied to the production control system, which may lead to information overload or data noise affecting system decision-making. In addition, most data standardization processes adopt fixed standardization formulas and cannot adapt to the dynamic characteristics of data changing over time. When the production environment changes rapidly, this is likely to result in inadaptability of control parameters, thus affecting production efficiency and product quality.
[0006] Based on the above analysis, the prior art mainly has the following defects in the production process optimization of electronic device safety interfaces. First, there is a lack of a multi-level optimization strategy that combines the global and local aspects, making it difficult to achieve global optimization in a complex production environment. Second, the application of existing intelligent optimization algorithms is mostly limited to single-objective optimization, lacking the ability of multi-objective comprehensive optimization and unable to balance production speed, product quality, and energy consumption. Third, data processing technologies are insufficient in dealing with the volatility and dynamic characteristics of real-time data, and traditional static data processing methods are difficult to provide real-time and accurate production control support. Finally, existing production control systems lack personalized optimization strategies when dealing with equipment differences and production task diversity and cannot be flexibly adjusted according to the status of specific equipment or the requirements of production tasks.
[0007] Therefore, how to provide a production process optimization method for electronic device safety interfaces based on fuzzy logic is an urgent problem to be solved by those skilled in the art. Summary of the Invention
[0008] An object of the present invention is to propose a production process optimization method for electronic device safety interfaces based on fuzzy logic. By introducing intelligent optimization technologies such as a multi-level fuzzy rule base, genetic algorithm, particle swarm optimization algorithm, and ant colony algorithm, the present invention realizes the global and local optimization of the production process of electronic device safety interfaces. The system can dynamically adapt to changes in the production environment and accurately control key parameters in the production process. At the same time, the present invention adopts an adaptive dynamic data processing technology and the construction of a personalized rule base to ensure the efficient operation of the production process under multi-objective optimization conditions, and has the advantages of strong self-adaptability, high precision, low energy consumption, and high production efficiency.
[0009] According to an embodiment of the present invention, a production process optimization method for electronic device safety interfaces based on fuzzy logic includes the following steps:
[0010] S1. Design and construct a multi-level fuzzy rule base, where the multi-level fuzzy rule base includes a first level, a second level, and a third level;

The input variables include the temperature, pressure, material flow rate, and production line load of each production line. The output variables include the production line speed adjustment, temperature setting, and pressure regulation, which are used to optimize the operating parameters of a single production line and ensure that each production line operates in the best state.
[0013] S4. The third layer uses an ant colony algorithm to optimize the specific process parameters in the fuzzy rule base. The input variables include the batching ratio, the fine-tuning parameters of the equipment, and the process error. The output variables include the ratio optimization, the equipment fine-tuning instruction, and the process parameter correction, which are used to precisely control the production process parameters and ensure further improvement of product quality and production efficiency.
[0014] S5. Through data acquisition and monitoring technology, data in the production process is obtained in real time, a multi-dimensional data set is constructed, and the multi-dimensional data set is transmitted to the central processing unit.
[0015] S6. Use the multi-dimensional data set to construct a personalized fuzzy rule base, automatically generate and optimize an exclusive rule base according to the individual differences of the equipment and task classification, and perform adaptive adjustment according to real-time data during the production process.

Through multiple iterations, the particle swarm gradually converges until the fitness function f 1 (X i ) converges to the set threshold or reaches the maximum number of iterations, and finally finds the particle position X 1 (X i ) that minimizes the fitness function f i , which is used as the optimized production line operation parameters, including the optimal production line speed adjustment, temperature setting, and pressure regulation.

[0051] S44. Each ant selects a path according to the selection probability P ij (t), determines a process parameter combination X j , and evaluates the effect through the multi-objective fitness function f 2 (X j ), and records the best process parameter combination found by each ant;
[0052] S45. Update the pheromone concentration, and adopt an adaptive pheromone evaporation mechanism and dynamic incremental update to update the pheromone concentration τ ij (t + 1) on each path:

[0080] The beneficial effects of the present invention are as follows:
[0081] First of all, by designing and constructing a multi-level fuzzy rule base, we have achieved comprehensive optimization control from the global to the local, from the macroscopic to the microscopic. The multi-level structure enables the system to separately handle the global production speed setting, the optimization of single production line parameters, and the refined control of specific process parameters, thus ensuring optimal control at different levels. This hierarchical optimization method can not only maintain the overall coordination of the system in a complex production environment but also accurately regulate the key nodes in production, effectively coping with the challenges of dynamic changes and uncertainties.

By combining the advantages of these algorithms, the efficient generation and dynamic optimization of the rule base are achieved. The genetic algorithm is responsible for the global optimization of the initial rule base to ensure that the system has strong adaptability and evolutionary ability in the initial stage; the particle swarm optimization algorithm is used to adjust the production line parameters in real time to ensure that each production line operates in the best state; the ant colony algorithm further optimizes the specific process parameters to ensure that the microscopic control in the production process reaches the best level. Through the organic combination of these intelligent optimization algorithms, the present invention not only improves the global search ability and convergence speed of the system but also enhances the adaptability and flexibility of the rule base, enabling the system to operate efficiently under multi-objective optimization.
[0083] In addition, the present invention overcomes the limitations of traditional static data processing methods by introducing adaptive dynamic data processing technology. The adaptive dynamic standardization technology can dynamically adjust according to the volatility of real-time data and the characteristics of time changes, ensuring the accuracy and timeliness of the data processing results. This data processing method not only improves the response speed of the system to real-time changes but also enhances the accuracy of control decisions, thereby effectively improving the stability and consistency of the production process.
[0084] More importantly, the present invention proposes a method for constructing a personalized fuzzy rule base, which can automatically generate and optimize an exclusive rule base according to the individual differences of each device and the requirements of specific production tasks. Through this innovative design, the system can customize the optimal control strategy for different devices and tasks, ensuring the best production effect under various conditions. This personalized optimization method greatly enhances the adaptability and flexibility of the system, enabling the production process to better cope with the complex and changeable production environment and meet diverse product requirements at the same time.
[0085] Finally, through visualization technology, the present invention presents the key data and optimization results in the production process in a graphical interface, supporting rapid decision-making and problem troubleshooting. This real-time visualization function not only improves the operability and user experience of the system, but also provides production managers with a more intuitive and convenient means of production monitoring and adjustment, further ensuring the efficiency and controllability of the production process.

[0163] Example 1:
[0164] To verify the feasibility of the present invention in implementation, the present invention is applied to an electronic equipment manufacturing factory, which mainly produces high-performance safety interfaces for smartphones and industrial control equipment. Due to the volatility of market demand and the diversity of product models, the production line needs to have a high degree of flexibility and adaptability to cope with the production of products in different batches and specifications. The problem faced by this manufacturer is how to improve production efficiency, reduce energy consumption, and address the challenges brought by equipment aging and production environment changes while ensuring product quality.
[0165] In practical applications, the manufacturer first designed and constructed a multi-level fuzzy rule base, and optimized the production process from global to local through this rule base. The generation and optimization of the first-level rule base mainly rely on genetic algorithms. Based on input variables such as total production demand, overall equipment health status, energy consumption rate, and production duration, global production speed setting, equipment utilization rate allocation, and energy consumption optimization strategies are output. After optimization, the global production speed setting has increased by an average of 12%, the equipment utilization rate has increased by 15%, and the energy consumption has decreased by about 8%.
[0166] In the second-level optimization, the manufacturer used the particle swarm optimization algorithm to dynamically optimize key parameters such as temperature, pressure, material flow rate, and production line load of each production line. Through this optimization, the operating parameters of each production line can be dynamically adjusted according to real-time data to ensure that the production line operates in the best state. Specifically, within a one-month production cycle, the product qualification rate has increased from the original 95% to 97.5%, and at the same time, the failure rate of the production line has decreased by about 20%, further reducing uncontrollable factors in the production process.
[0167] The optimization at the third level applies the ant colony algorithm for fine control of specific process parameters such as ingredient ratios, equipment fine-tuning parameters, and process errors. Through these optimizations, the micro-quality indicators of the product, such as the connection strength, wear resistance, and oxidation resistance of the interface, have been significantly improved. After comparing the production data for two months, the average connection strength of the optimized interface has increased by 10%, the wear resistance has increased by 8%, and the oxidation resistance has been improved by approximately 7%. The improvement of these indicators has greatly enhanced the competitiveness of the product in the market.
[0168] In terms of data collection and monitoring, the manufacturer obtains multi-dimensional data during the production process in real time through temperature, pressure, speed, flow, and vibration sensors arranged throughout the production line. Through the adaptive dynamic standardization technology proposed in the present invention, the accuracy and timeliness of data collection are ensured. Specifically, the manufacturer's data analysis team compared the data processing efficiency before and after implementing the present invention and found that the data transmission delay has been reduced by approximately 15%, and the impact of data noise has been reduced by more than 20%, thus significantly improving the response speed and decision-making accuracy of the production control system.
[0169] In addition, the manufacturer attaches great importance to the construction of a personalized fuzzy rule base. Due to the different service lives and states of production equipment, the personalized rule base proposed in the present invention can automatically generate fuzzy rules adapted to its specific needs based on the historical data and real-time status of each piece of equipment. Taking two pieces of equipment with different states in the factory as an example, Equipment A is a new equipment with good operating conditions; Equipment B has been used for five years and has certain aging phenomena. In actual production, the personalized rule base can set a more aggressive production speed and lower energy consumption strategy for Equipment A, while setting a more conservative production speed and more stable operating parameters for Equipment B. After three months of production practice, the production efficiency of Equipment A has increased by 18%, and the energy consumption has been reduced by approximately 10%; while for Equipment B, the product quality remains stable when the production speed is reduced by 5%, and the failure rate of the equipment has been reduced by approximately 25%.
