A high-precision powder dispensing device and method

Abstract

The invention discloses a high-precision powder distributing device, which solves the disadvantages that the existing automatic powder distributing device is difficult to achieve high precision, large range, fast speed and low device cost at the same time. The weighing balance also includes a powder cup, a rotary head, an installation box installed at the connection between the powder cup and the rotary head, and a motor assembly installed in the installation box to control the rotation of the rotary head; it also includes There are steering gear, mounting bracket and rotating bracket; the steering gear is placed horizontally, the mounting bracket is fixedly connected to the steering gear, and the two arms of the rotating bracket are installed on both sides of the steering gear and are controlled by the steering gear to rotate up and down in the vertical space; The installation box is fixedly installed on the side of the rotating bracket away from the steering gear, and the central axis of the rotating head is set in a direction away from the steering gear. The high-precision powder dispensing device of the present invention can efficiently and accurately carry out powder weighing, The cost is low and the universal practicability is high.

Description

technical field [0001] The invention relates to a powder distribution device, in particular to a high-precision powder distribution device and method. Background technique [0002] Materials discovery plays a central role in technological revolutions. Using the traditional trial-and-error approach, the typical time span from material discovery to commercialization averages 18 years. In today's rapidly evolving society, the pace of material discovery and commercialization has lagged significantly. A technology that could greatly accelerate materials discovery could have a transformative impact in our society. It is the demand and trend of development to realize the automation of new material research and development experiments. In the research and development of new solid inorganic materials, different solid powders are often mixed in a fixed ratio with a certain precision. In this way, new inorganic materials with better properties may be realized after high-temperature...

AI Technical Summary

Problems solved by technology

The small-sized device has high precision, but it is time-consuming and inefficient to dispense a large amount of powder

Large format devices can dispense large volumes of powder but with low precision

[0005] 2) At present, the powder dispensing device often needs a higher production process to achieve higher precision, and its cost is often high

[0006] 3) The current powder dispensing devices require high environmental requirements. For example, these powder dispensing devices often need to be equipped with static electricity removal devices to solve problems such as powder agglomeration and sticking to the wall
