Abstract

The invention relates to the field of injection molding part defect identification, in particular to an injection molding part wave flow mark identification method based on image processing. The method comprises the steps of obtaining an initial reference point according to a stripe direction, and obtaining a segmentation region according to a gray difference and a distance between each pixel point and each initial reference point; obtaining each vertical reference point pair and each horizontal reference point pair; obtaining each vertical segmentation boundary and each horizontal segmentation boundary according to the gray difference and the distance between each pixel point and each reference point pair; judging whether the wave flow marks exist in the injection molding part or not according to the vertical segmentation boundaries and the horizontal segmentation boundaries, achieving automatic identification of the wave flow marks so that the detection efficiency of the wave flow marks is improved.

Description

technical field [0001] The invention relates to the field of defect identification of injection molded parts, in particular to an image processing-based identification method for wave flow marks of injection molded parts. Background technique [0002] In the production process of injection molded parts, due to reasons such as excessive plastic moisture, inconsistent resin temperature, and low melt temperature in the cavity, there may be wave marks on the surface of injection molded parts. Flow marks of injection molded parts are a common defect of injection molded parts. Due to the unpredictability of the position of the wave flow mark area, most of the detection of wave flow marks on injection molded parts is done manually by those skilled in the art. Many injection molded parts undoubtedly increase a lot of workload, and the detection efficiency is low. Contents of the invention [0003] In order to solve the problem of low efficiency in detecting wave flow marks of inj...
