1Productivity
If silicon materials of different shapes and sizes are added uniformly by weight, then the feeding speed is uniform, but the melting speed of silicon materials fluctuates causing structural loss during crystal growing
Solution Approach 1:
The system performs preliminary scanning of silicon materials to obtain shape and size information before loading. Based on this advance information, the controller pre-calculates the optimal loading sequence and positions, ensuring that materials with different melting characteristics are strategically arranged to maintain stable melting speed throughout the feeding process.
Solution Approach 2:
The loading strategy is dynamically adjusted based on the scanned characteristics of each silicon material. The system adapts the loading sequence and positions in real-time according to the actual shape and size data, transforming a static uniform feeding approach into a dynamic optimized process that compensates for varying melting rates.
2Manufacturing precision
If a scanning assembly is added to collect silicon material information, then the loading strategy can be optimized, but the device complexity increases
Solution Approach 1:
The scanning assembly is integrated into the existing loading device structure, serving multiple functions: identifying material characteristics, determining loading positions, and optimizing feeding sequences. This multi-functional integration avoids adding separate independent systems, thereby reducing overall structural complexity while achieving precise loading control.
Solution Approach 2:
The system replaces complex mechanical sorting and positioning mechanisms with an intelligent control system that uses scanning data to digitally determine loading strategies. The controller algorithmically optimizes the loading sequence based on scanned information, substituting physical complexity with computational intelligence.
