The computer network is used to accurately control the production management, mainly for the data flow control of the entire tantalum wire production process, the temperature control of the equipment, the accurate extraction of the weight of the electronic scale, and the measurement data is imported into the computer production management system as the technical quality analysis data source, etc. .

Data control and management of technological process

The program code of the tantalum wire production management system is customized by the company's computer technicians in accordance with the production process requirements. The database uses Sqlserve, and the front-end development tool uses Mierosoft Accsso. The production process data and process flow of the entire tantalum wire process are managed and controlled by the computer.

Production process control of sintering furnace

The sintering furnace is mainly composed of a furnace body, a vacuum system, and an electric control system. In the furnace body, there are fixtures, electrodes, and heat insulation systems for installing tantalum bars. Sintering is one of the processes in the production of tantalum wire. There are dozens of sintering furnaces. Every 6 sintering furnaces form a furnace group, which is monitored by an industrial computer and communicates through the RS485 port. The industrial computer communicates with the sintering machine through the MOXAUport1650-8 serial server. The vacuum gauge, conductive instrument, etc. in the furnace are connected and communicated to collect real-time data of the power of the sintering furnace, vacuum level, alarm reminder output, etc., the industrial computer saves the real-time data on the industrial control server through the network, which is convenient for remote monitoring and query, etc. , The application software is written by MCGS configuration software, which mainly completes the functions of data storage, temperature and power curve drawing, and alarm processing.

Weight extraction of electronic scales

In each process of the tantalum wire production process, an electronic scale is used. For the accuracy of the weight, the weighing and fine winding process of the tantalum rod in the intermediate storage are all directly extracted by the electronic scale by the computer production system. The data source provided by the production system is more accurate. The daily production volume of the fine winding process is large. Each batch of silk produced must be weighed. When the batch of silk is finished and weighed, the production system directly transfers the weight of the batch of silk from the electronic The scale is extracted and stored in the wire row table, so that the next process product library does not need to re-scale, which reduces the labor intensity of employees

Data import of measuring instruments

In the drawing process, only the diameter data measured by the diameter gauge is saved in the computer connected to the diameter gauge in the form of an Excel table. The diameter import program is developed to connect the computer connected to the diameter gauge to the production of tantalum wire In the bureau city network, in the computer production management system, the diameter data of the production number is queried through the program code, and the found diameter data is extracted into the computer production management database, which reduces the number of diameter data recorded manually by the operator and then entered by the computer Cumbersome steps and avoid errors caused by manual entry.
