Intelligent crystal pulling system for single crystal furnace

Intelligent crystal pulling system for single crystal furnace

The intelligent one click crystal pulling system designed by one of the top three system suppliers in the single crystal furnace self-control industry is a new generation of intelligent crystal growing system for silicon single crystal growth furnaces. It is based on the high intelligence visual inspection algorithm developed by the intelligent machine SP7020H of Zhongke Era, which integrates calculation and control. It can achieve one click crystal pulling function through AI models, deep learning algorithms, etc. Recognizing and detecting images of the monocrystalline silicon production process, and combining with the monocrystalline furnace control system to perform special process algorithms based on the process scenario, automatic judgment and processing of key technical links in the growth process are achieved. Compared with traditional systems, it has the advantages of more intelligence, automation, efficiency, high precision, high stability, and high safety protection.

Difficulties in the Control System of Intelligent Crystal Pulling System for Single Crystal Furnace:

1. Complex control process

2. High requirements for measurement and control linkage speed

3. The visual detection algorithm is complex

 
Control system architecture:

Characteristics of SINSEGYE's solution:

1.Integrated Control and Computation

-A SP70 iComputer replaces the original upper level industrial control computer+PLC, reducing hardware equipment and lowering costs by about 30%.

-The data communication between the upper software and the soft PLC is effectively improved through shared memory or ACP, which enhances the speed of data exchange.

-Using virtualization technology, Windows blue screen or restart does not affect the running of real-time tasks.

2.Easy-to-use & Strong scalability

-The upper software communicates with the real-time side through shared memory, effectively improving the speed of data exchange.

-The diameter deviation has been increased from ± 0.7% to ± 0.5%, and some batches can reach ± 0.3%, greatly improving product quality
