A kind of LED glue and powder precision automatic batching equipment and batching method thereof

Abstract

The present invention relates to the field of precise instruments, particularly to precise and automatic LED glue and powder material preparing equipment and a precise and automatic LED glue and powder material preparing method. According to the present invention, the equipment adopts a myriabit precise weighing instrument, the precise weighing instrument does not move, automatic material feeding is performed by moving the LED glue and powder material equipment, and the same covering plate is used in the gap time of the glue or powder exchange so as to avoid the falling of the glue or powder into the material preparing cup; the precision of the LED glue is lower than the precision of the LED powder, such that the actual powder discharge amount is defined by the calculated requirement amount, ie., according to the actual glue discharge amount, the actual requirement amount of the LED powder is calculated through the proportions of the required amounts of the glue and the powder, wherein the proportion of the final powder discharge amount of the LED powder to the actual glue discharge amount is infinitely close to the actual proportion of the requirement amounts; and the color of the LED lamp has the high requirement on the proportion of the LDE glue and the powder, such that the LED lamp color effect can achieve the optimal requirement by discharge the glue and the powder according to the high accuracy proportion.

Description

technical field [0001] The invention relates to the field of precision instruments, in particular to a precision automatic batching device for LED glue and powder and a batching method thereof, which can achieve high-precision ratios for various powders and colloids. 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, manual proportioning is basically used, and the accuracy and repeatability are determined 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 ...

Problems solved by technology

In terms of accuracy, it is difficult to guarantee the accuracy in the range of ±0.1mg due to the heavy labor intensity of the operator

In terms of repeatability, due to the inconsistent operation level of each operator and the characteristics of various raw materials, it will lead to poor reliability and repeatability

[0004] In addition, some raw materials have special hygroscopicity. In an open environment, they are very easy to absorb moisture and deteriorate, which has a certain impact on the quality of the finished ingredients.

And because the environment of manual operation cannot be sealed, when using hygroscopic raw materials, the quality of ingredients cannot be well guaranteed

[0005] In the existing batching method, the ratio of LED glue and powder adopts the error control method, that is, the actual amount of glue and powder added is controlled within an error range, such as ±0.0003mg; in this way, when the actual amount of glue added is biased When the upper and lower limits are reached, the proportion of fans will fluctuate within a certain range, usually greater than 0.003%
