A LED production process optimization method based on big data technology

Abstract

The invention relates to an LED production process optimization method based on a big data technology, comprising the following steps: S1, establishing a dispensing data model, wherein, the dispensingdata model is used for representing the corresponding relationship between the original material parameters and the original dispensing amount; S2, obtaining the current dispensing amount through thedispensing data model; S3, obtaining the LED product by the current dispensing amount. The influence of fluorescent powder settling on LED products can be effectively reduced by the dispensing data model, and the luminous characteristics of the LED products can be kept consistent. The method can effectively improve the concentration degree of LED color coordinates and the falling Bin rate of themain color area in the mass production stage, improve the input-output ratio and productivity, increase the delivery rate and reduce the production cost. Through real-time monitoring the glue contentconcentration in the dispensing process, if the glue content concentration exceeds the threshold range or the on-line time exceeds the threshold range, timely detection and alarm increase the yield ofproducts and reduce abnormal losses.

Description

technical field [0001] The invention belongs to the technical field of artificial intelligence, and in particular relates to an LED production process optimization method based on big data technology. Background technique [0002] Any light can be made by mixing red, green, and blue colors in different proportions, which is the principle of the three primary colors. The principle of the three primary colors can be explained as follows: any light color in nature can be formed by mixing three light colors in different proportions; the three primary colors are independent of each other, and any light color cannot be composed of the other two light colors Composition; the saturation of the mixed color is determined by the ratio of the three light colors; the brightness of the mixed color is the sum of the brightness of the three light colors. For example, if the three kinds of light are mixed in the same proportion and reach a certain brightness, it will appear white (white lig...

Problems solved by technology

[0004] However, in the dispensing process of manufacturing white light LED products, the phosphor particles in the glue are affected by gravity and will settle during the dispensing process over time. Therefore, for the same tube of glue, the concentration of phosphor powder at the bottom is often greater than top

As a result, in the continuous dispensing process, although the amount of glue on different chips is the same, the phosphor concentration will decay over time, resulting in changes in the number of phosphor particles in the same volume of phosphor glue.

Phosphor particles are the light sources of red and green light, which makes it difficult to maintain consistent luminous levels of different chips in the same batch.
