Problems solved by technology

[0003] Anti-sedimentation powder is an important process material in the process of LED packaging. The quality of this powder is prone to static electricity and forms large lumps, which causes powder to accumulate in the powder hopper during the powder feeding process of the powder feeder. Phenomena such as powder voids in the powder mouth, it is difficult to meet the requirements of powder feeding accuracy

Abstract

The invention discloses a powder hopper and a powder feeder device thereof. The powder hopper comprises a powder hopper body; the rotating shaft is arranged in the powder hopper body, and a stirring rod is arranged on the rotating shaft; the first connecting block and the second connecting block are arranged at the two ends of the rotating shaft, hinged to the rotating shaft and rotationally connected with the two sides of the powder hopper body respectively; the eccentric rotating wheel is rotationally connected with the powder hopper body, one end of the eccentric rotating wheel is in sliding connection with the first connecting piece, and the end, away from the first connecting piece, of the eccentric rotating wheel is connected with a driving piece. Compared with the prior art, according to the powder hopper and the powder feeder device thereof, powder in the powder hopper can be effectively stirred, powder accumulation in the powder hopper and powder cavities in the powder discharging opening are avoided, and the powder feeding precision is higher.

Description

technical field [0001] The present application relates to the technical field of LED packaging, and more specifically, relates to a powder hopper and a powder feeder device thereof. Background technique [0002] Light Emitting Diode, referred to as LED, is a solid-state semiconductor device that can convert electrical energy into visible light. Semiconductor lighting has significant advantages such as long life, energy saving, environmental protection, and safety. It is widely used in lighting, display, and signal indicators. and other technical fields. [0003] Anti-sedimentation powder is an important process material in the process of LED packaging. The quality of this powder is prone to static electricity and forms large lumps, which causes powder to accumulate in the powder hopper during the powder feeding process of the powder feeder. Phenomena such as powder voids in the powder mouth are difficult to meet the requirements of powder feeding accuracy. [0004] Therefo...
