Abstract

The invention provides a plastic product quality detection method, which comprises the following steps: carrying out integrity scanning on a first plastic product through an omnibearing infrared scanner to obtain a first 3D infrared scanning model, the first 3D infrared scanning model being obtained by passing the first plastic product through the omnibearing infrared scanner according to a first posture; obtaining drawing parameter information of the first plastic product; performing 3D modeling according to the drawing parameter information to obtain a standard 3D model of the first plastic product; performing feature comparison on the first 3D infrared scanning model and a standard 3D model to obtain a first similarity value and a first distinguishing feature; obtaining position information of the first distinguishing feature and attribute information of the first distinguishing feature; and inputting the first similarity, the position information and the attribute information into a plastic product quality detection model to obtain a first quality detection result.

Description

technical field [0001] The invention relates to the related technical field of new generation information technology, in particular to a quality detection method of plastic products. Background technique [0002] Plastic products are widely used and widely distributed in various fields of human activities. Plastic products are synthetic polymer materials with good plasticity formed by injection molding or blister molding with natural or synthetic resin as the main component. Plastic has a certain strength, can be formed, and has good toughness, so that it can be used in a wide range of applications. [0003] In the production process of plastic products, because of its excellent plasticity and fluidity, the molding process is very important for the quality of plastic products. During the molding process, attention should be paid to the process parameters of extrusion, blow molding, and calendering, as well as the processing temperature. For the finished plastic preparation...
