Smart Steel Mill

Rebar online automatic counting & separation system:

“Online automatic counting system” is an automatic bar counting device that uses machine vision for target recognition, target tracking, and automatic positioning technology. The system collects the image of the bar moving on the chain bed and transmits it to the host computer. After image recognition and target tracking, the real-time counting function of the bar production process is realized; when the count value of each bundle reaches the set value, the chain bed is controlled to stop, indicate the position of automatic steel splitting, guide or control the start and stop of the steel moving machine, and can be used to display the steel splitting position in real time to guide the steel splitting. The system enters the next working cycle.

Bundle rebar online welding tag system:

Label welding robot is bar production line for steel enterprise specialized research and development of automatic weighing, automatic positioning, automatic input data, automatic printing product brands, automatic welding plate of multi-functional intelligent automation system, the product USES the integration integration design, 3 d image recognition, parts modular design, standardized production, product covers an area of small, fast;  Products replace the traditional production process using manual printing labels, manual data entry, manual welding signs and other tedious operations, to avoid the safety risks of workers on the site, to eliminate man-made printing signs, data entry, welding signs and other errors;  Reduce labor and labor intensity of operators to meet the needs of high-tempo and high-intensity production.  

Bundle wire hanging tag robot

robot hanging (welding) card system,The system is based on the industrial robot platform and image recognition technology, which realizes the automatic transmission, automatic printing and cutting, and automatic sorting of the signage data. and other functions. After the robot automatically takes the card, use the sign hook to hang the sign on the baling line used for bundling the coil. On the steel bar to ensure the reliability of the logo.

The robot can complete the requirements of printing, removing and welding 2 sign within 45s.

Laser marking machine :

The automatic billet marking machine produces traces by melting metal at high temperatures and high speeds with the laser to form the required characters. Customers can choose to use high-temperature paint, aluminum wire, or laser coding.

The system is equipped with an HMI human-machine interface server, which is mainly responsible for communication with the upper computer and automatic engraving;

Responsible for the selection of engraving fonts and fonts and the adjustment of on-site process parameters. The engraving equipment can correctly receive the engraving content transmitted by MES, and the end information will be fed back to the computer in time and the relevant operators will be notified by alarm;
