Process control and manufacturing execution systems in industrial production lines

Abstract

The invention discloses a process control and manufacturing execution system in an industrial production line, and the system comprises a central server which comprises a TPOK central database server and a main application server; a client service platform connected to the main application server; a base data and report query platform connected to the main application server; a test file server connected to the main application server; an information collection terminal connected to the main application server; and an ERP central database server connected to the TPOK central database server. The mutual transmission between the information of the main application server and the test file server and the information of the TPOK central database server is carried out. The system combines an internal coding method, a client coding method and a method of internal coding and client coding integration, completely meets the customization requirements of a client for a bar code, avoids the repeating of bar code information to the greatest extent, improves the production precision and information query speed, and achieves the traceability of raw materials and products.

Description

technical field [0001] The invention relates to a process control and manufacturing execution system in an industrial production line, which is used for system control in the production process of electronic integrated manufacturing. Background technique [0002] In the electronic foundry industry, especially the SMT manufacturing industry, the requirements for cost and accuracy are increasing, especially for small-batch and multi-variety manufacturing enterprises, the requirements for fine production are particularly prominent. To achieve the production of small-batch and multi-variety products, it is necessary to strictly control product types, production scheduling, material input and tracking, manufacturing process, testing process, quality and human input. For different customer needs and different design requirements, the machine It is difficult to achieve refined production if only relying on manual records and handwritten process cards, especially for a small-batch a...

Problems solved by technology

[0003] Production management: A complete production process includes feeding points, surface mounters, several inspection points and several test points (AOI / FCT / ICT). When multiple products are produced at the same time, each model selection The workstations may be the same or different. If you manage and trace the station information completely manually, the possibility of errors is very high. For the type of double-sided PCB or double-sided PCB, the complexity cannot be accurately recorded by hand. To control production and traceability;

[0004] Material management: For SMT machines, once the material is loaded incorrectly, the product repair rate and raw material throwing rate will be greatly increased, and a lot of manpower will be spent on testing and maintenance. When SMT is manually loaded, it is difficult to ensure completeness by manual inspection. accuracy;

[0005] In addition, for aviation and medical products, material information needs to be strictly traced, and this information is difficult to record manually;
