Trace-amount and balanced light-emitting diode (LED) fluorescent powder feeding device and operation method thereof

Abstract

The invention discloses a trace-amount and balanced light-emitting diode (LED) fluorescent powder feeding device and an operation method thereof. The trace-amount and balanced LED fluorescent powder feeding device can evenly feed fluorescent powder into a container through vibration of a vibrator fixed on a platform and comprises a material feeding funnel, a hopper, the vibrator and funnel supports. The vibrator is fixed on the platform, the hopper is integrally formed, a material carrying cavity is formed in one end of the hopper, a material feeding part is arranged at the other end of the hopper, the hopper is fixed on the vibrator, a small material feeding pipe is arranged in the hopper and communicated with the material carrying cavity, the other end of the small material feeding pipe is communicated with a large material feeding pipe, the other end of the large material feeding pipe is connected with a material discharging bend, a fine screen is arranged on the connection portion of the large material feeding pipe and the material discharging bend, the four funnel supports are arranged on two sides of the vibrator and horizontally fixed, and the other ends of the funnel supports are fixed on the material feeding funnel which is fixed right above the material carrying cavity of the hopper through the funnel supports.

Description

technical field [0001] The invention relates to the field of precision instruments, in particular to a micro-balanced feeding device for LED fluorescent powder and an operating method thereof. Background technique [0002] In the fields of test analysis, trace element addition, fine chemical industry, etc., the accuracy of ingredients is required to be very high. Generally, it needs to reach ±10mg, and the requirement for higher occasions needs to reach ±0.1mg. [0003] At present, in the occasions where precise proportioning and high-precision ingredients are required, the manual proportioning method is basically adopted, and the accuracy and repeatability are determined manually by the operator. In terms of accuracy, it is difficult to guarantee the accuracy in the range of ±0.1mg due to the heavy repetitive labor intensity of operators. In terms of repeatability, due to the inconsistent operation level of each operator and the characteristics of various raw materials, th...
