Description

Technical Field

[0001] The present invention relates to the technical field of production quality management, and specifically to an intelligent production quality management method based on AI training. Background Art

[0002] In modern manufacturing, production quality management is the key to ensuring product compliance, improving customer satisfaction and reducing production costs. With the rapid development of artificial intelligence technology, AI models have advantages in data processing and analysis. By learning from historical data, they can predict quality problems that may occur in the production process.

[0003] With the rapid development of the manufacturing industry, production quality management has become increasingly important. Traditional production quality management methods mainly rely on manual inspection and statistics, which have problems such as low efficiency, poor accuracy, and slow response speed; key parameters in the production process are monitored through statistical methods (such as control charts) to ensure that they are within a controllable range; through sampling inspection, some products are randomly selected from the production batch for inspection to infer the quality of the entire batch of products.

[0004] However, traditional production quality management methods have many limitations in practical applications. For example, manual experience is not only inefficient, but also easily affected by subjective factors of inspectors, resulting in deviations in test results. Statistical methods cannot monitor the entire production process in real time and comprehensively, and there is a lag. Through sampling inspection, the sampling results may not fully represent the quality of the entire batch of products, which may lead to unqualified products entering the market. Moreover, the ability to analyze the large amount of data accumulated by enterprises in the production process is limited. Therefore, traditional production quality control methods can no longer meet the requirements of modern manufacturing for high-quality and high-efficiency production. There is an urgent need for an intelligent production quality management method based on AI training to improve the accuracy, real-time and intelligence level of production quality control.

If it is greater than or equal to the threshold, it means that the production quality intelligent management is good, otherwise it means that the production quality intelligent management is abnormal, reminding the production management personnel to pay attention and take corresponding measures. For example, if it is found that the model predicts inaccurately in some cases or there are other problems, timely feedback can be given to the model developers; if it is found that it is a problem with the production management data, feedback will be given to the production management personnel to adjust the process parameters, replace equipment parts, etc.

The method for intelligent production quality management based on AI training according to claim 1, characterized in that: The AI ​​model verified in S4 includes the following steps: S4.1: Construct sample data set: Match the third target data set of production quality management of each product with the corresponding quality label to obtain each sample data, each sample data includes the third target data set of production quality management of each product and the corresponding quality label; then construct a sample data set from each sample data, and divide the constructed sample data set into a training data set n_tra and a test data set n_tes; finally, obtain the sample data construction quality index SDI through big data analysis technology, , ba represents the balance of quality labels, that is, the ratio of qualified labels to unqualified labels. If SDI is less than the threshold, repeat step S4.1, otherwise go to S4.2; S4.2: Input the training data set in the sample data set constructed in S4.1 into the AI ​​model for training, calculate the output of the model through forward propagation, and compare it with the real quality label; then use the mean square error loss function to calculate the error L(θ), , M represents the number of training samples, f(Np)I represents the output result, f(Np) 0I Represents the true result; then adjust the θ value through the gradient descent algorithm to solve the minimum value of the loss function, and then monitor the convergence of the model. Its convergence model is: , where K represents the number of model iterations, α is the model learning rate, and when the value of the loss function remains unchanged, the training is completed; finally, the trained AI model is output, and the parameters of the AI ​​model are recorded, including the network structure, the number of model iterations, and the model learning rate; S4.3: Verify the trained AI model output by S4.2 through the test set, obtain the verification accuracy PRE and recall REC of the test set, and obtain the F1 score of the test set. ,If the F1 score is greater than the threshold, it means that the AI ​​model verification has passed, otherwise repeat S4.

8. The method for intelligent production quality management based on AI training according to claim 1, characterized in that: The results evaluated as abnormal in S6 are obtained by first obtaining the number of products n_s, the total number Tn_s, the number of correct warnings n_al, and the total number of warnings Tn_al whose AI model prediction results are consistent with the actual quality labels, and obtaining the production quality intelligent management index PQMI, , a1 and a2 represent the corresponding weight coefficients; then the production quality intelligent management index PQMI is compared with the threshold. If it is greater than or equal to the threshold, it means that the production quality intelligent management is good, otherwise it means that the production quality intelligent management is abnormal.
