RFID intelligent production process management for photovoltaic crystal pulling plants

1. Project Background

With the increasing challenges of global energy shortage and climate warming, clean energy has become one of the main goals of domestic energy development. As an important part of clean energy, the photovoltaic industry has made great progress in the past few decades and has become one of my country's strategic emerging industries. In the context of intelligent manufacturing, the photovoltaic industry needs to integrate new technologies, control the production process, improve efficiency, and reduce costs to maintain industry competitiveness.

The production process of the photovoltaic industry is relatively complex, and it needs to face challenges such as discrete manufacturing and harsh working environment. The traditional manual paper recording method is prone to errors, and the production data and quality data in the manufacturing process cannot be tracked in real time. In addition, the data collection of each process is difficult to integrate, and it is impossible to provide sufficient data support for the MES information construction.

2. Industry Pain Points

Discrete manufacturing and complex process flow: The manufacturing process of the photovoltaic industry is discrete, and the process flow involved is relatively complex, and it is also necessary to deal with harsh working environments.

Difficulty in manual paper recording and data tracking: The traditional manual paper recording method is prone to errors, and the production data and quality data in the manufacturing process cannot be tracked in real time.

Difficulty in process data integration: The data collection of each process is difficult to integrate, and it is impossible to provide sufficient data support for the MES information construction.

3. Solution

In order to solve the above problems, the photovoltaic crystal pulling plant needs to adopt a reliable and intelligent RFID solution to achieve efficient operation of the production process. At each Library-borrowing-machine-touch-query-intelligent-terminal-all-in-one-machine.html target='_blank'>workstation, it is necessary to accurately identify and read the monocrystalline silicon information on the tray, and connect with the MES system to realize the collection and transmission of production information data, as well as abnormal processing and other functions, so as to realize equipment data analysis and data informatization construction.

On the production automation line of the photovoltaic crystal pulling plant, the modbus-connected-PLC-UHF-RFID-915M-all-in-one-production-line-management.html target='_blank'>rfid industrial reader starts data collection from the cutter. After the cutter cuts the silicon rod, the robot arm places the silicon rod on the tray and writes the first data to bind the silicon rod information with the tray information. In the subsequent automated production line, each process is equipped with an RFID Reader for data collection, and the last process is untied after completion.

IV. Project Benefits

Real-time tracking and data integration of production information: RFID products provide real-time statistical data of pallet information for the customer's MES system, and realize the tracking and control of monocrystalline silicon wafers in the entire process. Through RFID technology, the information of monocrystalline silicon on the pallet can be accurately identified and read, and connected with the MES system to realize the collection and transmission of production information data. Real-time tracking and data integration make the process of the production workshop intelligent, visual and transparent.

Improvement of production efficiency and reduction of costs: The identification of pallets by RFID high-frequency industrial readers optimizes the production process. The application of RFID technology makes the production process more efficient, reduces the time and error rate of manual operation, thereby improving production efficiency. Through intelligent analysis and processing of data, intelligent management is realized, which promotes cost reduction and efficiency improvement.

Reduce labor intensity and improve product yield: The successful implementation of RFID technology reduces the labor intensity of front-line workers, makes the production process more intelligent and automated, not only improves production efficiency, but also reduces the human error rate, thereby improving the product yield. The accuracy of automated production detection helps to reduce the human error rate and provides a model for the standardization and standardization of the entire industry.
