Problems solved by technology

[0004] In short, product quality is determined by various parameters in the production process. For the situation where a certain parameter exceeds the threshold, early warning and screening can be easily performed. However, it often happens that the final product is unqualified for all production parameters. In response to this situation, the current detection and control methods cannot be solved, resulting in problems in actual production that can only be solved by trial and error, wasting a lot of manpower and material resources

Abstract

The invention discloses an intelligent quality control method and system. The method comprises the following steps: collecting production parameter data related to parts of a production line; inputting the production parameter data into a deep learning model, predicting whether products produced on site are qualified or not and outputting the result, giving qualified scores for the qualified products, refining the product quality further, giving correction suggestions for the unqualified products and transmitted to an execution unit for execution, conducting actual detection on the corrected products by the execution unit, and transmitting the result to the server so as to strengthen or improve the adjustment strategy of the server, wherein the deep learning model is obtained through training by taking a set loss function as a target, and each training sample represents a corresponding relation between the production parameter data and whether the related product is qualified or not. The method can be applied to actual production, predicts and guides a production result, enables a quality control system to be integrated and intelligent, and solves problems which cannot be solved by manpower.

Description

technical field [0001] The present invention relates to the technical field of intelligent manufacturing, and more specifically, to an intelligent quality control method and system. Background technique [0002] Quality control is an important link in the production process, which is directly related to the survival of the manufacturer. For spare parts or simple products, whether it is qualified or not depends on on-site inspection, but for assembled parts or complex products, the situation will be much more complicated. Every part is qualified, and the assembly parameters meet the requirements, but the final measured product function is not qualified from time to time. For example, for the production of air compressors, it is processed and assembled by many parts and hundreds of processes. Since it adopts standardized production, each part has quality inspection. If a certain parameter exceeds the threshold, the machine can automatically alarm and screen . However, since...
