MES-based production management system

Abstract

The invention relates to the technical field of automation control, and particularly discloses an MES-based production management system. The system comprises a loading mechanism, a carrier, a first acquisition module, a second acquisition module, a third acquisition module and an identification module; the loading mechanism is used for loading the camera module onto the carrier; the first acquisition module is used for acquiring a two-dimensional code on the camera module, identifying and extracting a product serial number; the second acquisition module is used for acquiring the two-dimensional code on the carrier after the camera module is loaded on the carrier, and identifying and extracting the number of the carrier; the identification module is used for establishing association between the product serial number and the carrier number; the third acquisition module is used for acquiring the two-dimensional code on the carrier in the processing procedure and the detection procedure, identifying and extracting the number of the carrier; and the identification module is further configured to retrieve an associated product serial number based on the carrier number. By adopting the technical scheme of the invention, the probability of two-dimensional code scanning identification errors can be reduced.

Description

technical field [0001] The invention relates to the technical field of automation control, in particular to an MES-based production management system. Background technique [0002] Manufacturing Execution System (MES) is a workshop-oriented management information system, including order data release, production scheduling and production instruction data release, production process execution monitoring, on-site production data collection, data statistical processing and reporting, etc. Through the above management The system can make the whole production process more orderly, standardized and visualized. [0003] In order to realize functions such as production process execution monitoring and on-site production data collection, it is necessary to track each device in production. For example, in the manufacture of camera modules, a series of processing and inspection procedures are required, such as black spot detection, auto-focus, glue dispensing, and burning. Usually, a ...

Problems solved by technology

[0004] However, the camera module is usually used on small devices such as mobile phones, and its size is small, so the area of ​​the QR code printed on the casing must also be small, which undoubtedly increases the difficulty of scanning the QR code and leads to the probability of scanning and recognition Moreover, the number of camera modules processed by the factory can reach 100,000 or even millions per month, and each camera module will go through multiple processes during processing; the scanning base is large, and the probability of scanning and recognition is high. It will lead to a high total number of scan failures, affecting production efficiency
