Abstract
The invention relates to the technical field of automobile part detection, in particular to a plastic thermal riveted assembly monitoring method and device. The method comprises the steps that a to-be-detected workpiece is conveyed to a uniform optical detection view field position by using an auxiliary conveying and positioning module; a powerful alignment light source module shines obliquely togenerate a shadow region, and image collection is conducted by using a camera module; it is judged whether the to-be-detected workpiece is qualified or not through image analysis, and quality evaluation is conducted on the welding conditions through an SVM classifier. By means of the plastic thermal riveted assembly monitoring method, it can be achieved that missing installation, defect identification and quality evaluation of finished products and semi-finished products of automobile doors and other parts can be quickly monitored at a high precision on line, and the production efficiency andquality of an automatic assembly line are improved.
