At present, the market generally relies on the manual proportioning method, and the mechanism of matching the powder throughout the process by relying on the vibration source, resulting in low efficiency and large labor cost, thereby developing a high power. The automation device of LED phosphor blending ratio is of great help to change the current industry status, and also has important application value for the LED packaging industry.
