Abstract

L'invention concerne une aiguille de distribution et un distributeur. L'aiguille de distribution comprend : un tube et une tête en communication l'un avec l'autre. La tête d'aiguille est en communication avec une partie d'ouverture en forme de cor. La partie d'ouverture présente un diamètre intérieur augmentant progressivement dans le sens de distribution, et est aplatie dans un sens perpendiculaire au sens de distribution au niveau de l'extrémité arrière du sens de distribution. La partie d'ouverture est constituée d'un matériau flexible, incompatible avec un adhésif distribué. Pendant la distribution, lorsque la partie d'ouverture flexible est en contact avec une puce à DEL, l'extrémité arrière de la partie d'ouverture peut être aplatie pour recouvrir la puce à DEL, et l'adhésif distribué peut être injecté par le tube d'aiguille dans la puce à DEL le long de la tête de l'aiguille et de la partie d'ouverture, ce qui évite le débordement de l'adhésif et garantit l'efficacité de distribution; du fait d'une meilleure correspondance entre la partie d'ouverture et la puce à DEL, des zones aveugles d'injection dans la cavité de LED peuvent être réduites, la régularité de distribution améliorée, et la performance et la qualité des produits finis à DEL garanties.
