A door and window welding control method and system based on artificial intelligence

Abstract

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. This method obtains a shadow stitching image with multiple shadow areas by setting three cameras with different viewing angles and their own light sources. According to the distribution of the camera and the distribution of the material shadow area, multiple cross-sectional shadow distribution maps are obtained, and the curvature triangle representing the morphological characteristics of the weld edge is obtained through the distribution information of the shadow segmentation points, and obtained by the difference of the curvature triangles of all cross-sectional shadow distribution maps Weld edge roughness. The depth of the weld is obtained by the proportion of the area of ​​the shaded area of ​​the darkest weld itself. The quality of the weld is judged according to the roughness of the edge of the weld and the depth of the weld, and the adjustment direction is obtained when the quality requirements are not met, and the welding pressure is controlled and adjusted. The invention obtains the morphological characteristics of the weld through the shadow information of the weld, quickly and accurately judges the quality of the weld and provides reference 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 The welding plate is withdrawn and the materials are butted together until cooling to complete the welding.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...

AI Technical Summary

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
