Problems solved by technology

Welding quality will affect the safety performance of doors and windows, because improper operation during the welding process or improper selection of machine parameters will lead to insufficient weld strength of plastic doors and windows, and there is a risk of cracking in the subsequent use process, which poses a safety hazard to users
Therefore, it is necessary to carry out qualified inspections for the welds of plastic doors and windows, and adjust machine parameters in time to avoid potential safety hazards in plastic doors and windows.
[0003] In the existing technology, the temperature information at each position of the weld can be obtained by infrared detection method, and the strength of the weld can be represented by the temperature information, but the infrared detection will be affected by irrelevant temperature sources, and the quality of the weld cannot be accurately judged, and errors are prone to occur. check

Abstract

The invention relates to the technical field of image processing, in particular to a door and window welding control method and system based on artificial intelligence. According to the method, a shadow spliced image with a plurality of shadow areas is obtained by arranging three cameras which are different in view angle and provided with light sources. A plurality of section shadow distribution diagrams according to the distribution of the cameras and the distribution of the material shadow areas, curvature triangles representing the morphological characteristics of the weld edge are obtained according to the distribution information of the shadow segmentation points, and the roughness of the weld edge is obtained according to the difference of the curvature triangles of all the section shadow distribution diagrams. The depth of the welding seam through the area proportion of the shadow region of the welding seam with the deepest color. The welding seam quality is judged according to the edge roughness of the welding seam and the depth of the welding seam, the adjusting direction when the quality requirement is not met is obtained, and the welding pressure is controlled and adjusted. The morphological characteristics of the welding seam are obtained through the shadow information of the welding seam, the welding seam quality is rapidly and accurately judged, and reference is provided for welding control.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an artificial intelligence-based door and window welding control method and system. Background technique [0002] Hot plate welding is one of the common processes in the production process of UPVC plastic doors and windows. During the hot plate welding process, the welding material can be accurately positioned in the machine through the positioning plate, and the pressure is applied to the plastic door and window material through the pressure clamp. Under the action of the pressure, the end faces of the two sections of material close to the welding plate are melted. The welding plate is withdrawn and the materials are butted together until cooling to complete the welding. Therefore, the welding pressure is the main parameter affecting the welding quality. Welding quality will affect the safety performance of doors and windows, because factors such as improper operation...
