Problems solved by technology

[0003] At present, most of them detect bubble defects by collecting images and performing texture analysis on the images to determine the quality of injection molded parts. However, when bubbles exist inside the injection molded part, bubble defects cannot be accurately detected only based on surface texture.

Abstract

The invention relates to the technical field of data processing, in particular to an injection molding part bubble defect detection and cause analysis method and an artificial intelligence system. And constructing a first change curve of a first gray value sum of each row of gray values and a second change curve of a second gray value sum of each column of gray values in the inverted gray-scale map, and calculating an influence degree corresponding to each wave crest according to wave crest distribution of the first change curve and the second change curve so as to obtain a detection parameter of the injection molding part, the quality of the injection-molded part is accurately confirmed according to detection parameters, meanwhile, the process automation is improved, the screening precision is improved, and time and loss consumed by manual detection are reduced.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and an artificial intelligence system for bubble defect detection and cause analysis of injection molded parts. Background technique [0002] Plastic products are widely used in life, and during the production process of plastic products, air bubbles may be generated on the surface or inside. There are basically two types of air bubbles. One is air bubbles. The main reason is that the injection speed is too fast, and the plastic flow cannot force all the air in the mold cavity to be discharged from the exhaust groove. The air is mixed into the plastic to form bubbles. , commonly found on the surface or inside of injection molded parts; the other is vacuum bubble, as the name suggests, vacuum bubble is due to the thick outer wall of the product, the center is cooled slowly and the surface cools quickly, and the surface shrinkage tends to pull the material over, U...
