[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] 1. In this invention, the sequential feeding of LED beads is achieved through the cooperation of the vibrating feeding tray and the feeding track. The vibration causes the beads to enter the rack in a specific posture, providing a correct placement basis for subsequent processing and ensuring the smooth progress of the production process. The limiting components inside the rack can limit and organize the beads to a certain extent, making the beads more orderly during the racking process. The rotating feeding assembly inside the feeding frame continuously picks up materials from the discharge rack and feeds them into the pre-processing rack, achieving efficient feeding operations and improving production efficiency.
