Abstract

The invention relates to the technical field of LED production, in particular to LED diffusion powder and a preparation method and device thereof.The LED diffusion powder comprises a screening box, a hopper, a mounting frame, a filter sieve, a spring, a pushing module, a vibration assembly, a crushing box, a crushing roller, a driving assembly, a first storage frame and a second storage frame, the hopper communicates with the screening box, and the mounting frame is arranged in the screening box; the filter sieve is fixedly connected with the mounting frame, one end of each spring is fixedly connected with the mounting frame, the other end of each spring is fixedly connected with the sieving box, the pushing module is fixedly connected with the sieving box, the vibration assembly is fixedly connected with the sieving box, the crushing box is communicated with the sieving box, and each driving assembly is arranged in the crushing box. The first storage frame is detachably connected with the crushing box, the second storage frame is detachably connected with the screening box, particles formed by adhesion of raw materials are treated through the structure, and the production quality of LED diffusion powder is improved.

Description

technical field [0001] The invention relates to the technical field of LED production, in particular to LED diffusion powder and a preparation method and device thereof. Background technique [0002] The LED powder is very important, and the powder is prepared with phosphor powder and glue. Since the phosphor is small particles, it will precipitate or be unevenly distributed in the glue, which will affect the light spot of the LED after it is clicked. Diffusion powder is to add a certain proportion to the glue, which can play the effect of anti-precipitation and optical diffusion. [0003] At present, in the production process of LED diffusion powder, the raw materials are easy to stick to form particles, resulting in poor production quality of LED diffusion powder. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide an LED diffuser powder and a preparation method and device thereof, which aims to solve the technical problem that the raw ...
